Description

Technical Field

[0001] This invention relates to the field of building structure technology, and more particularly to a multifunctional roofing system. Background Technology

[0002] In modern residential buildings, there are generally two types: multi-story residential buildings and detached residential buildings. Multi-story residential buildings are a common structure built by real estate companies. These buildings typically only meet the daily living needs of an average family. They are characterized by cramped layouts, limited functionality, roofs that cannot be reopened after construction, and high energy consumption. Of course, some detached residential buildings also exist in suburban areas or towns. These buildings are often designed and built by the residents themselves, who are able to construct their own foundations, walls, and roofs. However, they still suffer from the problem of limited functionality. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, one of the objectives of this invention is to provide a multifunctional roofing system to solve the technical problem of the single function of existing buildings.

[0004] One of the objectives of this invention is achieved through the following technical solution:

[0006] A plurality of roof supports are arranged at intervals, and inclined mounting beams are provided on both sides of the roof supports;

[0007] A plurality of spaced carrier supports are arranged side by side along the length of the mounting beam between two mounting beams. The carrier supports are connected to the mounting beams and can be rotated from 0° to 180°. The carrier supports are provided with a first surface and a second surface. The first surface is provided with a first functional plate and the second surface is provided with a second functional plate.

[0008] A rain shield bracket is disposed in the gap between adjacent carrier brackets. The rain shield bracket is provided with a rain shield plate that can be raised and lowered. The rain shield plate is located above the gap between adjacent carrier brackets to block rainwater and guide the rainwater to the first functional plate.

[0009] When each of the first functional panels faces upward, the first functional panels are spliced ​​together to form a plane, and the rain shield descends to press against the first functional panel.

[0010] Optionally, the rain shield bracket includes a rain shield plate and a lifting mechanism, the lifting mechanism includes a lifting power element and a transmission assembly, and the rain shield plate is disposed on the transmission assembly.

[0011] Optionally, the transmission assembly includes a first transmission rod, a first lead screw, and a lifting member with internal threads. The first transmission rod is connected to the lifting power element, and the first transmission rod is also connected to the first lead screw to drive the first lead screw to rotate. The lifting member is sleeved on the first lead screw.

[0012] The rain shield is mounted on the lifting member.

[0013] Optionally, the rain shield bracket further includes at least three limiting rings. At least two of the limiting rings are sleeved on the first lead screw to position the first lead screw, and at least one of the limiting rings is sleeved on the lifting member to limit the displacement of the lifting member and prevent the lifting member from disengaging from the first lead screw when it moves up and down.

[0014] Optionally, the rain shield bracket is provided with an inclined rain shield plate, and the lifting mechanism is connected to the rain shield plate to drive the rain shield plate to move up and down; or

[0015] The rain shield bracket is provided with two inclined and oppositely arranged rain shields, and a support member is provided between the two rain shields to support their tilt angle and force. The lifting mechanism is connected to the two rain shields to drive the two rain shields to perform lifting and lowering movements.

[0016] Optionally, the first side edge of the first surface of the carrier support is provided with a first connecting groove, and the first side edge and the second edge of the second surface of the carrier support are respectively provided with a second connecting groove and a third connecting groove;

[0017] When the carrier support is laid on the roof support, the first side edge of the carrier support is embedded in the third connecting groove of the adjacent carrier support.

[0018] Optionally, the first connecting groove, the second connecting groove, and the third connecting groove are all provided with waterproof grooves, and waterproof strips are provided in the waterproof grooves.

[0019] Optionally, the carrier support includes a carrier frame and a rotating shaft, one end of which is fixedly connected to the carrier frame, and the other end of which is rotatably connected to the mounting beam from 0° to 180°.

[0023] In this invention, the surface facing upwards can be changed by flipping the carrier support, allowing either the first or second functional panel to be laid on the roof support, thus expanding the functionality of the multi-functional roof system. For example, when the second functional panel is a solar panel (solar power generation) or a light reflector (concentrated solar power generation), the multi-functional roof system can utilize solar energy to generate electricity, exhibiting excellent environmental protection and energy-saving effects. Similarly, when the first functional panel is a waterproof panel (as described below), it improves waterproof performance. When the carrier supports are positioned at other angles, such as vertically, the interior and exterior are connected, facilitating the penetration of outdoor air and light into the interior, providing good environmental permeability. Furthermore, the rain shield can be raised and lowered, bringing it closer to or tightly against the carrier support, preventing rainwater from entering the house through the gap between the rain shield and the carrier support. This raising and lowering motion of the rain shield enhances the waterproofing effect. Attached Figure Description

[0044] Below, in conjunction with the appendix Figure 1 To be continued Figure 14 The present invention will be further described in detail below with specific implementation methods. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0045] like Figures 1 to 8 As shown, a multifunctional roofing system includes several roof supports 1, several carrier supports 2, and rainproof supports 3. The roof supports 1 are arranged at intervals, and inclined installation beams 11 are provided on both sides of the roof supports 1. The roof supports 1 are the support structure of the multifunctional roofing system and have a supporting function.

[0046] Each carrier bracket 2 is arranged side-by-side between two mounting beams 11 along the length of the mounting beam 11. The carrier bracket 2 is rotatably connected to the mounting beam 11. The carrier bracket 2 has a first surface and a second surface. The first surface has a first functional plate 23, and the second surface has a second functional plate 24. The roof support 1 has an inclined mounting beam 11 for supporting the carrier bracket 2 and the aforementioned two functional plates. At the same time, the carrier bracket 2 is rotatably installed on the mounting beam 11 along the length of the mounting beam 11. Each carrier bracket 2 is laid on the roof support 1, and can simultaneously have its first surface facing upward, that is, each first functional plate 23 facing upward, or its second surface facing upward, that is, each second functional plate 24 facing upward, or each carrier bracket 2 can be in other angles. In this embodiment, by flipping the carrier bracket 2, the upward-facing surface can be changed, so that the first functional plate 23 or the second functional plate 24 is laid on the roof support 1, thus expanding the function of the multifunctional roof system. For example, when the second functional panel 24 is a solar panel (solar power generation) or a light energy reflector (concentrated power generation), the multifunctional roofing system can generate electricity using solar energy, which has a good environmental protection and energy-saving effect. Similarly, when the first functional panel 23 is the waterproof panel mentioned below, it can improve the waterproof performance.

[0047] When each carrier support 2 is at another angle, such as when each carrier support 2 is in a vertical state, the indoor and outdoor spaces are connected, allowing outdoor air and light to penetrate into the indoor space, resulting in good environmental permeability.

[0048] In addition, the rainproof bracket 3 is installed in the gap between adjacent carrier brackets 2. The rainproof bracket 3 is equipped with a rainproof plate 31 that can be raised and lowered. The rainproof plate 31 is located above the gap between adjacent carrier brackets 2 to block rainwater and guide it to the first functional plate 23. By setting up the rainproof bracket 3 and using the rainproof plate 31 to block rainwater, the waterproof performance of the multi-functional roofing system is ensured. Furthermore, the rainproof plate 31 can be raised and lowered. Lowering the rainproof plate 31 allows it to approach or press against the carrier bracket 2, preventing rainwater from entering the house through the gap between the rainproof plate 31 and the carrier bracket 2. The raising and lowering of the rainproof plate 31 improves the waterproof effect. Raising the rainproof plate 31 expands the space below it, providing space for the carrier bracket 2 to flip. After the carrier bracket 2 flips, the rainproof plate 31 lowers again. When each of the first functional plates 23 is facing upwards, the first functional plates 23 are spliced ​​together to form a plane, and the rainproof plate 31 lowers to press against the first functional plate 23.

[0049] Therefore, in this embodiment, a carrier support 2 with a rotatable first functional plate 23 and a second functional plate 24 is provided on the roof support 1, thereby expanding the function of the multi-functional roof system. At the same time, a rain shield support 3 is provided to increase the waterproof effect of the multi-functional roof system. Furthermore, the lifting and lowering of the rain shield 31 facilitates the flipping and function switching of the carrier support 2, further improves the waterproof performance of the multi-roof system, and ensures the stability of the carrier support 2 in wind and snow.

[0050] In some embodiments, the rain shield bracket 3 includes a rain shield 31 and a lifting mechanism 32. The lifting mechanism 32 includes a lifting power element 321 and a transmission assembly, and the rain shield 31 is disposed on the transmission assembly. In this embodiment, the lifting mechanism 32 drives the rain shield 31 to move up and down. Specifically, the lifting power element 321 outputs power, which is transmitted through the transmission assembly. The transmission assembly drives the rain shield 31 to move, thereby causing the rain shield 31 to move up and down.

[0051] Specifically, the transmission assembly includes a first transmission rod 322, a first lead screw 323, and a lifting member 324 with internal threads. The first transmission rod 322 is connected to the lifting power element 321, and is also connected to the first lead screw 323 to drive the lead screw 323 to rotate. The lifting member 324 is sleeved on the first lead screw 323. The rain shield 31 is fixed to the lifting member 324. The lifting power element 321 outputs power, and the first transmission rod 322 transmits power to the first lead screw 323, causing the first lead screw 323 to rotate. The first lead screw 323 is threadedly engaged with the lifting member 324. The rotation of the first lead screw 323 causes the lifting member 324 to move up and down, thereby driving the rain shield 31 to rise or fall.

[0052] In addition, the rain shield bracket 3 also includes at least three limiting rings 33. At least two limiting rings 33 are sleeved on the first lead screw 323 for positioning the first lead screw 323, and at least one limiting ring 33 is sleeved on the lifting member 324 for limiting the position of the lifting member 324 and guiding the lifting member 324 to rise and fall. The lifting member 324 does not detach from the first lead screw 323 when it moves up and down.

[0053] Regarding the specific transmission method of the aforementioned first transmission rod 322 and first lead screw 323, specifically, the first transmission rod 322 and the first lead screw 323 are perpendicular or approximately perpendicular to each other. The first transmission rod 322 and the first lead screw 323 transmit power in the form of a worm gear. Of course, it can also be transmitted by two meshing bevel gears, thereby causing the first lead screw 323 to rotate.

[0054] Specifically, the rain shield 31 includes an inclined rain shield 31, and the lifting mechanism 32 is connected to the rain shield 31 to drive the rain shield 31 to move up and down.

[0055] The rain shield bracket 3 is an umbrella-shaped bracket with an umbrella-shaped cross-section. The rain shield bracket 3 includes two inclined and oppositely arranged rain shield plates 31. A support member is provided between the two rain shield plates 31 to support their inclination angle. The lifting mechanism 32 is connected to the two rain shield plates 31 to drive the two rain shield plates 31 to perform lifting and lowering movements.

[0056] In some embodiments, the rain shield bracket 3 also has a connector, which is used to support the two rain shields 31 to maintain a fixed angle as a whole, and at the same time support the rain shields 31. The connector is also connected to the lifting mechanism 32, specifically to the lifting member 324.

[0057] In some embodiments, such as Figure 8 As shown, the first side edge of the first surface of the carrier support 2 is provided with a first connecting groove 211, and the first side edge and the second edge of the second surface of the carrier support 2 are respectively provided with a second connecting groove 212 and a third connecting groove 213. When the carrier support 2 is laid on the roof support 1, the first side edge of the carrier support 2 is embedded in the third connecting groove 213 of the adjacent carrier support 2.

[0058] like Figure 9 As shown, when the first surface faces upward, the first side edge of the carrier bracket 2 is embedded in the third connecting groove 213 of the adjacent carrier bracket 2, while the second side edge of the carrier bracket 2 is embedded in the first connecting groove 211 of the adjacent carrier bracket 2. When the first surface faces upward, the carrier brackets 2 form a tight overlap, which has a higher sealing and waterproof effect. The first functional plate 23 is laid flat to form a flat surface, which facilitates rainwater sliding off and provides rain protection and waterproofing in rainy weather.

[0059] like Figure 10 As shown, when the second surface faces upward, the second side edge of the carrier bracket 2 is embedded in the second connecting groove 212 of the adjacent carrier bracket 2. At this time, the second functional plate 24 is oriented and subjected to force, so that the trapezoidal roof bracket 1 has other functions that are different from the first functional plate 23.

[0060] In some embodiments, such as Figure 8 As shown, the first connecting groove 211, the second connecting groove 212, and the third connecting groove 213 are all provided with waterproof grooves, and waterproof adhesive strips 25 are provided in the waterproof grooves. The waterproof grooves and waterproof adhesive strips 25 in the first connecting groove 211, the second connecting groove 212, and the third connecting groove 213 can increase the sealing performance when adjacent carrier supports 2 are connected, and improve the overall waterproof effect of the trapezoidal house support.

[0061] Specifically, the aforementioned carrier support 2 includes a carrier frame 21 and two rotating shafts 22. The rotating shafts 22 are located on the side of the carrier frame 21 near the mounting beam 11. One end of the rotating shaft 22 is fixedly connected to the carrier frame 21, and the other end of the rotating shaft 22 is rotatably connected to the mounting beam 11.

[0062] In some embodiments, such as Figure 11 , Figure 13 As shown, to improve the convenience of angular positioning of the carrier support 2, the carrier support 2 also includes a limiting shaft 26, and the mounting beam 11 is provided with a limiting groove 112 for supporting and limiting the limiting shaft 26. By setting the limiting shaft 26 on the carrier support 2 and the limiting groove 112 on the mounting beam 11, the extreme positions of the carrier support 2 are limited, thereby improving the convenience of angular positioning of the carrier support 2.

[0063] Furthermore, such as Figure 11 , Figure 13 As shown, the mounting beam 11 is provided with a mounting hole 111 for mounting the rotating shaft 22. The mounting hole 111 is located between two adjacent limiting grooves 112. The carrier bracket 2 is rotatably connected to the rotating shaft 22 and the mounting hole 111, allowing the carrier bracket 2 to be flipped. In addition, since the mounting hole 111 is located between two adjacent limiting grooves 112, the limiting shaft 26 can be inserted into the limiting groove 112 regardless of whether the first surface of the carrier bracket 2 is facing up or the second surface is facing up, the limiting shaft 26 can be inserted into the limiting groove 112, thereby limiting the carrier bracket 2.

[0064] Specifically, the first functional panel 23 is a waterproof panel, and the second functional panel 24 is a solar panel. In rainy weather, the first functional panel 23 faces upwards on the first surface of the carrier support 2, and is laid flat on the carrier support 2, guiding rainwater to slide off. Simultaneously, the first functional panels 23 are connected and laid together through the aforementioned first connecting groove 211, second connecting groove 212, and third connecting groove 213, providing excellent sealing and waterproofing.

[0065] In some embodiments, such as Figure 12 , Figure 13 As shown, the roof support 1 includes a carrier drive device 4, which is connected to each carrier support 2 to drive the carrier support 2 to flip its surface.

[0066] For the aforementioned driving device, the carrier driving device 4 includes a carrier power element 41, a rack 42, and several gears 43. The carrier power element 41 is connected to the rack 42, which is mounted on the roof support 1. Each gear 43 is mounted on the rotating shaft 22 and meshes with the rack 42. The carrier power element 41 drives the rack 42 to reciprocate, and the rack 42 drives the gears 43 to rotate forward or backward. The gears 43 drive the corresponding carrier support 2 to rotate via the rotating shaft 22, thereby switching the orientation of different functional panels.

[0067] In addition, such as Figure 14As shown, the carrier drive device 4 also includes an output gear 44 and a connecting rod 45; the connecting rod 45 is rotatably connected to the output gear 44 via a rotating shaft, the rotating shaft is parallel to the axis of the output gear 44, and the connection position of the rotating shaft and the output gear 44 is offset from the axis of the output gear 44. The connecting rod 45 is connected to the rack 42, and the output gear 44 and the connecting rod 45 form a crankshaft connection structure, so that one end of the connecting rod 45 makes a circular motion, and the other end drives the rack 42 to make a repetitive linear motion.

[0068] For the aforementioned drive device, such as Figure 12 , Figure 13 As shown, the carrier drive device 4 includes a carrier power element 41, a worm gear 46, and a worm wheel 47. The carrier power element 41 is connected to the worm gear 46, which is mounted on one side of the roof support 1. The worm wheel 47 is mounted on the rotating shaft 22 and meshes with the worm gear 46. The carrier power element 41 drives the worm gear 46 to rotate forward or backward, which in turn drives the worm wheel 47 to rotate forward or backward. The worm wheel 47, through the rotating shaft 22, drives the carrier support 2 to rotate, thereby switching the orientation of different functional plates.

[0069] like Figure 1 As shown, in this embodiment, the roof supports 1 can be arranged back-to-back, forming a back gap. That is, the higher side of the two roof supports 1 is close to each other, and the lower side is far away from each other. The rainproof support 3 is arranged in the middle of the two roof supports 1 and above them. The rainproof panel 31 covers the back gap between the two roof supports 1. In this way, the roof supports 1 expand the coverage area of ​​the roof system. The rainproof support 3 covers the gap between the two back-to-back roof supports 1, preventing rainwater from falling into the gap between the two roof supports 1. At the same time, the overall shape is umbrella-like, which can guide rainwater to flow onto the roof supports 1. The two roof supports 1 guide rainwater to flow to both sides of the building, forming a double-sided water-repellent structure.

[0070] Of course, multiple roof supports 1 can be arranged linearly, which can extend the coverage area of ​​the roof supports 1, and there are gaps between adjacent roof supports 1.

[0071] Two roof supports 1 set back to back form a support group, such as Figure 2 As shown, the support groups can also be arranged linearly, with multiple sets of roof supports 1 arranged back-to-back along a linear path. The rain shelter supports 3 cover not only the gaps created by the back-to-back arrangement but also the gaps created by the linear arrangement. Thus, the gaps in the roof supports 1 include ridge gaps and inter-roof gaps, and the rain shelter supports 3 are distributed along these gaps. Specifically, the rain shelter supports 3 include longitudinal supports located on the ridge gaps and transverse supports located on the inter-roof gaps.

[0072] The longitudinal and transverse supports can be connected together and raised and lowered synchronously, or the part of the longitudinal support near the transverse support can cover the transverse support, so that the longitudinal and transverse supports can be raised and lowered independently, reducing interference or disturbance caused by synchronous raising and lowering.

[0073] Of course, nothing is ever truly permanent. Just as rocks are gradually weathered by wind and snow, the multifunctional roofing system of this invention also requires maintenance to ensure its waterproofing performance under the long-term influence of the external environment. Because the carrier support 2 and the first functional plate 23, which enable the waterproofing of this system, are modular, miniaturized, and visualized, maintenance points can be quickly located and targeted, significantly saving manpower, material resources, and financial resources. Since the waterproofing of the multifunctional roofing system is achieved through simple mechanized movement between components, and these components are quite simple, the reliability and durability of the system's waterproofing performance are very high.

[0074] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial modifications made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
