BACKGROUND OF THE PRESENT INVENTION
Field of Invention

The present invention relates to a roof structure, and more particularly to a functional roof construction method and arrangement, wherein a plurality of functional roof modules are assembled to form a rigid roof structure for selectively providing multiple functions of solar energy collection, thermal insulation, sound insulation, wireless network system, and the like.

Description of Related Arts

Architects have many roof designs in the building industry over the last few decades since the roof serves as a building envelop to effectively protect the interior of the building. A conventional roof structure comprises a plurality of roof beams supported on a supporting frame of the building to define a roof surface thereon, and a plurality of roof layers overlaid on the roof surface to provide heat insulation and waterproof feature for protecting the building. Accordingly, the roof layers can be a waterproof roofing membrane and a plurality of roof materials, such as roof shingles or tiles, stacked on the roofing membrane. Accordingly, extra heat insulation material, such as fiberglass insulation or foam insulation, must be added under the roof surface within the attic of the building to control the interior temperature of the building effectively. In other words, the conventional roof structure provides poor heat insulation. In addition, the conventional roof structure has several drawbacks.

The conventional roof structure is hard to repair especially when a portion thereof is damaged. For example, when there is a water leakage, the constructers must remove the roof materials and replace the waterproof roofing membrane. It is time consuming and is a waste of material since the roof materials cannot be re-used. The repairing cost of the damaged roof structure is relatively high to include the labor cost of the constructers. In addition, the conventional roof structure has a limited service lifespan depending on the material thereof In other words, the life expectancy of the roof varies between different roof materials. For example, the life expectancy of the asphalt roof shingles is about 15 to 20 years. Therefore, the house owner should replace the entire roof structure before the lifespan of the roof structure is end.

Even though many roof designs are found to improve the roof materials and/or the efficiency of the roof, the basic frame structure of the roof has not be changed. In other words, the foundation of the roof structure is still constructed by the waterproof roofing membrane and the roof materials. The improved roof materials can only prolong the lifespan of the roof structure and can enhance the efficiency of thereof. However, the above existing problems cannot be solved.

A significant improvement of the conventional roof structure is the solar roofs. Accordingly, the solar roof, which is a rooftop solar system, comprises a plurality of solar panels mounted on top of the roof surface via a panel supporting frame. However, the solar panels are costly and required licensed roof contractors to install. Because of the weight of the solar panels, the licensed roof contractors must calculate the stress and the loading requirements of the roof structure before the installation of the solar panels. Therefore, the rooftop solar system may not be able to install on the old roof structure. In addition, the installation of the rooftop solar system requires drilling on the roof structure, such that the existing roof structure will be damaged.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The following description is disclosed to enable any person skilled in the art to make and use the present invention. Preferred embodiments are provided in the following description only as examples and modifications will be apparent to those skilled in the art. The general principles defined in the following description would be applied to other embodiments, alternatives, modifications, equivalents, and applications without departing from the spirit and scope of the present invention.

Referring to FIGS. 1 to 5 of the drawings, a functional roof construction arrangement according to a preferred embodiment of the present invention is illustrated, wherein the functional roof construction arrangement of the present invention is arranged for mounting on a roof frame of a building to replace the existing roof structure, as shown in FIG. 6. In particular, the roof frame of the building has a predetermined pitch to define a slope that the roof frame is constructed to have an inclined configuration at a sloping direction.

According to the preferred embodiment, the functional roof construction arrangement comprises a plurality of functional roof modules 100 being assembled together to form a rigid roof structure for the roof frame of the building. Depending the size of the roof frame, various numbers of functional roof modules 100 are selectively assembled to form the roof structure having size and shape corresponding to the roof frame of the building. Accordingly, each of the functional roof modules 100 comprises a module housing 101 and a roof functional unit 102.

The module housing 101 comprises two supporting frames 10. Each of the supporting frames 10 comprises a supporting wall 11 extended vertically, and a supporting arm 12 perpendicularly extended from the supporting wall 11 to define an upper portion of the module housing 101 above the supporting arm 12 and a lower portion of the module housing 101 below the supporting arm 12 for attaching to the roof frame. Accordingly, the supporting wall 11 has a base platform 111 formed at a bottom edge for attaching to the roof frame. FIGS. 18A and 18B illustrates the supporting frame 10 coupled at different roof frames. In FIG. 18A, the supporting frame 10 is coupled at a roof beam via screws. FIG. 18B, the supporting frame 10 is coupled at a I-shaped roof reinforcing bar via screws.

Each of the supporting frames 10 further comprises a supporting ridge 13 extended from the supporting wall 11 at a position parallel to and below the supporting arm 12 to define a ridge slot 131 between the supporting ridge 13 and the supporting arm 12. In particular, a length of the supporting arm 12 is longer than a length of the supporting ridge 13. The supporting wall 11 has an outer side and an inner side, wherein the supporting arm 12 and the supporting ridge 13 are spacedly extended from the inner side of the supporting wall 11. In addition, the supporting wall 11 of each of the supporting frames 10 has a hollow structure to form a double-wall structure for enhancing the rigidity of the supporting frame 10 and to define an air chamber therewithin for providing thermal and/or sound insulation of the module housing 101. Therefore, the outer side of the supporting wall 11 is defined at a side surface of one of the double-wall structure while the inner side of the supporting wall is defined at a side surface of another double-wall structure.

Each of the supporting frames 10 further has a sliding slot 14 longitudinally formed at a top edge of the supporting wall 11, wherein an elongated opening of the sliding slot 14 is configured to face at a direction with respect to an extension direction of the supporting arm 12. As shown in FIG. 7, when the supporting frames 10 are spacedly aligned with each other, the supporting walls 11 of the supporting frames 10 are extended in parallel. The supporting arms 12 of the supporting frames 10 are spacedly aligned with each other end-to-end and the supporting ridges 13 of the supporting frames 10 are spacedly aligned with each other end-to-end. In addition, the sliding slots 14 of the supporting frames 10 are spacedly aligned and facing with each other.

The roof functional unit 102 comprises different functional panel units supported by the module housing 101 at different levels. In particular, the roof functional unit 102 comprises a first roof functional panel unit 20 slidably supported by the supporting ridges 13 of the supporting frames 10, a second roof functional panel unit 30 slidably supported by the supporting arms 12 of the supporting frames 10 at a position below the first roof functional panel unit 20, and a third roof functional panel unit 40 slidably engaged with the sliding slots 14 of the supporting frames 10 at a position spacedly above the first roof functional panel unit 20. Accordingly, the first through third roof functional panel units 20, 30, 40 provide different functions for the building.

As shown in FIGS. 2 to 5, the first roof functional panel unit 20 comprises a plurality of thermal insulation panels 21 and a plurality of panel dividers 22. Two edge portions of each of the thermal insulation panels 21 are supported by the supporting ridges 13 of the supporting frames 10 respectively. In particular, the two edge portions of each of the thermal insulation panels 21 are slid at the ridge slots 131 of the supporting frames 10 respectively. It is worth mentioning that each of the thermal insulation panels 21 is made of thermal insulation material to form a radiant barrier for reflecting radiant heat when the sun heats the functional roof construction arrangement of the present invention. Preferably, each of the thermal insulation panels 21 is also made of sound insulation material to form a soundproof roof structure.

Each of the panel dividers 22 is located and sealed between every two of the thermal insulation panels 21 to retain the thermal insulation panels 21 in position. Accordingly, each of the panel dividers 22 is made of rigid material, such as metal, and has a hollow structure to define an air cavity therein to serve as a thermal and/or sound insulation chamber. In addition, each of the panel dividers 22 has two side surfaces wherein two adjacent thermal insulation panels 21 are biased against the side surfaces of the panel dividers 22, such that the panel divider 22 is sandwiched between two thermal insulation panels 21. It is worth mentioning that a gap between the panel divider 22 and the thermal insulation panel 21 is sealed by sealing material such as silicone.

As shown in FIGS. 2 and 3, two ends of each of the panel dividers 22 are attached between the supporting frames 10 to enhance the rigidity of the module housing 101. Accordingly, each of the supporting ridges 13 has a retention rim 132 extended upwardly at the ridge slot 131. Each of the panel dividers 22 has two bottom slits 221, wherein the retention rims 132 of the supporting ridges 13 are engaged with the bottom slits 221 of the panel divider 22 to support and retain the panel divider 22 in position. It is worth mentioning that the panel dividers 22 provide multiple functions of reinforcing the structure of the module housing 101, retaining the thermal insulation panels 21 in position, and supporting the second roof functional panel unit 30 above the thermal insulation panels 21. It is appreciated that two ends of each of the panel dividers 22 can be attached between the supporting frames 10 by attaching the ends of the panel divider 22 at the supporting ridges 13 of the supporting frames 10 via screws respectively.

According to the preferred embodiment, the first roof functional panel unit 20 comprises a sound insulation layer 23 mounted in the module housing 101 at the lower portion thereof at a position below the thermal insulation panels 21.

The second roof functional panel unit 30 comprises at least a waterproof panel supported by the supporting arms 12 of the supporting frames 10 respectively. In particular, the waterproof panel can be a water guard drainage panel 31, wherein two edge portions of the water guard drainage panel 31 supported by the supporting arms 12 of the supporting frames 10 respectively. The water guard drainage panel 31 is made of waterproof material to prevent water, such as rain, entering under the water guard drainage panel 31. As supporting the water guard drainage panel 31 at the supporting arms 12 of the supporting frames 10, the water guard drainage panel 31 is supported at the upper portion of the module housing 101, such that the water is blocked by the water guard drainage panel 31 to prevent the water entering into the lower portion of the module housing 101. In other words, no water will be entered into the first roof functional panel unit 20. It is worth mentioning that since the length of the supporting arm 12 is larger than the length of the supporting ridge 13, when the second roof functional panel unit 30 is slidably supported by the supporting arms 12 of the supporting frames 10, the two side edge portions of the second roof functional panel unit 20 are covered by the supporting arms 12 respectively to ensure no water to be entered into the lower portion of the module housing 101.

As shown in FIGS. 3 and 4, the water guard drainage panel 31 has a corrugated cross section and defines a plurality of water drainage channels 311 extended longitudinally along the sloping direction of the roof structure so as to guide the water to flow downwardly. In other words, when the module housing 101 is mounted on the roof frame of the building at the slope thereof, an up-slope side of the module housing 101 and a down-slope side thereof are correspondingly defined with respect to the sloping direction of the roof frame. Therefore, the water is collected and is guided to flow along the water drainage channels 311 from the up-slope side of the module housing 101 to the down-slope side thereof at the sloping direction of the roof structure.

As configuring the water guard drainage panel 31 with said corrugated cross section, the water drainage channels 311 are defined on a top side of the water guard drainage panel 31 and a plurality of engaging channels 312 are formed on a bottom side of the water guard drainage panel 31. As shown in FIGS. 2 to 4, each of the supporting arms 12 has a L-shaped coupling free end 121 coupled at the side portion of the water guard drainage panel 31. In particular, the coupling free ends 121 of the supporting arms 12 are selectively engaged with the engaging channels 312 at the side portions of the water guard drainage panel 31 respectively. Therefore, the two side portions of the water guard drainage panel 31 are locked at the supporting arms 12 of the supporting arm 10 to retain the water guard drainage panel 31 in position so as to form a water barrier for preventing the water entering into the lower portion of the module housing 101.

It is worth mentioning that the water guard drainage panel 31 is also coupled to the panel dividers 22 not only for reinforcing the strength of the water guard drainage panel 31 to be secured within the module housing 101 but also for preventing any vibration within the module housing 101 when wind force is applied thereto.

The second roof functional panel unit 30 further comprises a water collecting gutter 33 coupled to the module housing 101 for collecting the water from the water guard drainage panel 31 so as to prevent the water flowing to the lower portion of the module housing 101. Accordingly, the water collecting gutter 33 is coupled at the down-slope side of the module housing 101. Preferably, the water collecting gutter 33 has a U-shaped cross section to have an upper gutter cover 331 coupled at the top edges of the supporting frames 11 of the supporting frames 10 and a bottom gutter tray 332 aligned with the water guard drainage panel 31 to collect the water therefrom. It is worth mentioning that the bottom gutter tray 332 of the water collecting gutter 33 is located above the lower portion of the module housing 101 to prevent the water leaking thereinto. Therefore, the functional roof construction arrangement of the present invention has a built-in gutter, such that no rain gutter is required for mounting at the roof frame of the building. It is appreciated that the water collecting gutter 33 can be formed as a water collecting pipe line connected to the down-slope side of the module housing 101 to collect the water from the water guard drainage panel 31.

As the water is collected, the collected water can be recycling used. Accordingly, the second roof functional panel unit 30 further comprises a water reservoir 34 communicatively connected to the water collecting gutter 33 to store the water from the water guard drainage panel 31. A water purification/filtration system can be incorporated with the water reservoir 34 to purify/filter the water, such that the user is able to drink the water or use the water to water the garden, to flush the toilet and the like.

According to the preferred embodiment, the third roof functional panel unit 40 comprises a plurality of solar collecting panels 41 slidably coupled with the sliding slots 14 of the supporting frames 10 to support at the top edges of the supporting walls 11 in an edge-to-edge manner. The solar collecting panels 41 are electrically connected with each other for collecting solar energy. The third roof functional panel unit 40 further comprises a solar energy convertor 42 electrically linked to the solar collecting panels 41 for converting the solar energy into electrical energy. Accordingly, the solar energy convertor 42 can be directly connected to an electrical meter of the building or to a rechargeable battery 43 for storing the electrical energy. It is worth mentioning that the third roof functional panel unit 40 is supported spacedly apart the second roof functional panel unit 30 to form an air circulation chamber therebetween for ensuring the air circulation within the upper portion of the module housing 101.

According to the preferred embodiment, the third roof functional panel unit 40 further comprises two panel blockers 32 coupled at the top edges of the supporting frames 10 respectively to retain the solar collecting panels 41 for preventing the solar collecting panels 41 being slid downwardly when the module housing 101 is inclinedly supported on the roof. Accordingly, each of the panel blockers 32 has a L-shaped cross section mounted at the supporting wall 11 to bias against a bottom edge corner of the solar collecting panel 41. Preferably, the panel blockers 32 are coupled at the top edges of the supporting frames 10 respectively at the down-slope side only because the solar collecting panels 41 will slide from the up-slope side of the module housing 101 to the down-slope side thereof.

It is worth mentioning that the panel blockers 32 also serve as two blockers to retain the solar collecting panels 41 for preventing the solar collecting panels 41 being slid downwardly when the module housing 101 is inclinedly supported on the roof In addition, the panel blockers 32 are coupled at the top edges of the supporting frames 10 to serve as two water drainage gutters for guiding the water to flow from the sliding slots 14 to the water guard drainage panel 31. In particular, the panel blockers 32 are coupled at the top edges of the supporting frames 10 respectively to align with the sliding slots 14 thereof respectively for guiding the water to flow from the sliding slots 14 to the water guard drainage panel 31. As shown in FIG. 13, each of the L-shaped panel blockers 32 is mounted at the supporting wall 11 defining an upper water entrance communicating with the sliding slot 14 and a bottom water exit for draining the water from the sliding slot 14 to the water guard drainage panel 31. Accordingly, the panel blockers 32 are coupled at the top edges of the supporting frames 10 respectively at the down-slope side only because the water will only flow along the sliding slots 14 from the up-slope side of the module housing 101 to the down-slope side thereof.

As shown in FIGS. 1 and 14, the functional roof construction arrangement further comprises a module connector 50 for connecting two of the functional roof modules 100 with each other side-by-side. Accordingly, each of the supporting frames 10 further comprises a locking ridge 15 extended from the supporting wall 11. In particular, the locking ridge 15, having L-shaped locking rim, is extended from the outer side of the supporting wall 11 at a direction opposite to the supporting arm 12. Preferably, the locking ridge 15 is extended to align with the supporting arm 12.

The module connector 50 has two locking edges 51 and an indented water guiding channel 52 extended between the locking edges 51, wherein when two of the module housings 101 are located side-by-side, the locking edges 51 of the module connector 50 are engaged and water-sealed with the locking ridges 15 of the two module housings 101 respectively so as to lock up the functional roof modules 100 with each other. Preferably, the locking edges 51 of the module connector 50 are interlocked with the locking ridges 15 of the two module housings 101 respectively. It is worth mentioning that the water collecting gutter 33 can be configured that the length of the water collecting gutter 33 is long enough to couple with two or more module housings 101, such that the water collecting gutter 33 can collect the water from different water guard drainage panels 31 at different module housings 101 to the water reservoir 34 at the same time. In addition, the water collecting gutter 33 can also collect the water from the water guiding channel 52 of the module connector 50 as well.

The functional roof construction arrangement further comprises a functional operating module 60 coupled to at least one of the functional roof modules 100, wherein functional operating module 60 is arranged to provide an additional function for the building. Accordingly, the functional operating module 60 has a waterproof housing 61 coupled at the lower portion of the module housing 101 and an operation unit 62 received in the waterproof housing 61 to provide the additional function for the building.

As shown in FIGS. 1 and 15, the waterproof housing 61 is mounted under the bottom gutter tray 332 of the water collecting gutter 33, such that no water will flow to the waterproof housing 61. The waterproof housing 61 provides a double-protection to ensure the protection of the operation unit 62.

The operation unit 62 can be an electronic device received in the waterproof housing 61. For example, the operation unit 62 can be a security system, wherein alarm detection equipments, such as security lights and/or surveillance cameras, can be mounted under the waterproof housing 61 while the security wiring system is hidden within the waterproof housing 61. Different sensors, such as light sensors or motion sensors, can also installed under the waterproof housing 61. It is worth mentioning that the operation unit 62 can be configured as an Internet router and/or communication device to be protected by the waterproof housing 61. It is worth mentioning that the rechargeable battery 43 of the third roof functional panel unit 40 can also supported in the waterproof housing 61.

Another application of the operation unit 62 is to configured as a system controller of a water heating system for heating up water for use in the building, a system controller of an energy conversion system for converting energy from natural gas or water into useable energy, such as electrical energy for the building. For example, the collected water can be electrolyzed into hydrogen and oxygen as the fuel. The operation unit 62 can also be an air filtration/purification system for filtering and/or purifying air into the building. The operation unit 62 can also be a climate monitoring system capable of integrating with any external satellite network, providing ground-base data, and forecasting changes in weather and climate.

It is worth mentioning that the functional roof construction arrangement of the present invention provides enough space, such as the lower portion of each of the module housings 101, that the water piping system, the air conditioning piping system, and/or the electrical wiring system of the building can be hidden in the functional roof construction arrangement so as to organize the water/air/electrical wiring configuration and to save the installation space of the building.

According to FIGS. 7 to 15, the configuration of the functional roof module 100 is shown as follows. A width of the functional roof module 100 must be initially determined. Accordingly, depending the size of each of the first, second, and third functional panel units 20, 30, 40, the width of the module housing 101 can be determined. Preferably, the widths of the first, second, and third functional panel units 20, 30, 40 should be the same. Accordingly, the two supporting frames 10 are positioned side-by-side to configure as the width of the module housing 101, as shown in FIG. 7. The module housing 101 further comprises a plurality of reinforcing cross bars 16 spacedly coupled between the supporting frames 10 to retain the width of the module housing 101 and to strengthen the module housing 101, as shown in FIG. 8. Each of the reinforcing cross bars 16 has two ends coupled at the supporting walls 11 of the supporting frames 10 respectively, such as by welding or screws. In particular, the reinforcing cross bars 16 are coupled between the supporting walls 11 at the lower portion of the module housing 101. Preferably, a second set of the reinforcing cross bars 16 can also coupled between the supporting walls 11 at the upper portion of the module housing 101 at a position between the second roof functional panel unit 30 and the third roof functional panel unit 40, as shown in FIG. 11. Preferably, the reinforcing cross bars 16 are H-shaped cross bars or C-shaped cross bars.

Once the distance between the supporting frames 10 are retained by the reinforcing cross bars 16, i.e. the width of the module housing 101, the supporting walls 11 of the supporting frames 10 are extended in parallel. The supporting arms 12 of the supporting frames 10 are spacedly aligned with each other end-to-end and the supporting ridges 13 of the supporting frames 10 are spacedly aligned with each other end-to-end. In addition, the sliding slots 14 of the supporting frames 10 are spacedly aligned and facing with each other, as shown in FIG. 7.

Then, the thermal insulation panels 21 and the panel dividers 22 of the first roof functional panel unit 20 can be slid into the module housing 101 in an alternating manner to support by the supporting ridges 13 of the supporting frames 10, as shown in FIG. 9. The water guard drainage panel 31 of the second roof functional panel unit 30 can be slid into the module housing 101 to support by and lock with the supporting arms 12 of the supporting frames 10, as shown in FIG. 10. The panel blockers 32 can be coupled at the top edges of the supporting frames 10 respectively to align with the sliding slots 14 thereof respectively. Once the first and second roof functional panel units 20, 30 are installed into the module housing 101, the solar collecting panels 41 of the third roof functional panel unit 40 can be slidably coupled with the sliding slots 14 of the supporting frames 10 to support at the top edges of the supporting walls 11, as shown in FIG. 12. The panel blockers 32 can be coupled at the top edges of the supporting frames 10 respectively to align with the sliding slots 14 thereof respectively, as shown in FIG. 13. It is worth mentioning that the solar collecting panels 41 will be blocked by the panel blockers 32 for preventing the solar collecting panels 41 being slid downwardly when the module housing 101 is inclinedly supported on the roof. Therefore, the assembly of the functional roof module 100 will be completed.

In order to install the functional roof construction arrangement to the roof frame of the building, the roof area of the roof frame must be measured to determine the numbers of functional roof modules 100 to be used. Then, the functional roof modules 100 aligned in a desired array corresponding to the shape of the roof frame, and the functional roof modules 100 are coupled with each other via the module connectors 50, as shown in FIG. 14.
