Description

Technical Field

[0002] Photovoltaic modules are installed on the enclosure structure of the existing color steel tile building roof, referred to as the "constructive photovoltaic building system (BAPV installation method)", which consists of photovoltaic modules + purlin support system + inverter electrical system, etc., and is connected to the distribution AC side of the building and connected to the grid, with a single power generation function.

[0003] At present, BAPV installation of photovoltaic modules generally uses metal clamps to fix them on the crest of the roof color steel tiles through bolts. The roofs of existing steel structures are generally constructed with metal corrugated tiles with anti-corrosion and anti-rust materials sprayed on the surface. The main shapes of metal corrugated tiles are trapezoidal, angular, upright lock-edge, and 360-degree bite. The metal purlins are fixed on the metal clamps, and then the photovoltaic modules are fixed and locked with metal blocks and bolts.

[0004] However, the distance between the peaks is greater than 15cm. When formed by roller rolling equipment, the clamp installation method can easily cause deformation or even tearing of the existing trapezoidal, angular, upright lock-edge, and 360-degree bite-type metal profiled tiles under the pulling, traction, and suction of wind. In rainy and snowy weather, it can cause roof leaks, affecting the use of building space and causing property losses, affecting the settlement and collection of photovoltaic electricity bills for self-use.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one skilled in the art to which this invention pertains. The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] See also Figures 1-4, which is a schematic structural diagram of a metal roof BIPV support mechanism provided in one embodiment of the present invention, wherein the metal roof BIPV support mechanism is provided on the end surface of a metal corrugated tile 100, which is provided on a roof purlin 200. The metal roof BIPV support mechanism includes a first bracket 500 and a second bracket 600 arranged along a first direction of the metal corrugated tile 100, and a third bracket 700 arranged along a second direction. The first direction and the second direction are arranged perpendicular to each other, wherein:

[0037] See also Figure 6 To connect the metal corrugated tile 100 and the roof purlin 200, a first bracket 500 is installed on the end surface of the metal corrugated tile 100. Fasteners 560 are used at both ends of the first bracket 500 to connect the metal corrugated tile 100 and the roof purlin 200. The first bracket 500 spans the corrugated tile 100's peak 110. The first bracket 500 includes a first spanning portion 510 and first abutting portions 520 symmetrically located on either side of the first spanning portion 510. The first spanning portion 510 abuts against the corrugated tile 100's peak 110.

[0038] In this embodiment, the first cross-section 510 can be set to a trapezoidal shape, and the first supporting portion 520 can be set to a square shape. The first supporting portion 520 is provided with a mounting pin 540 at one end away from the first cross-section 510. The mounting pin 540 is provided with a mounting through hole 550. Waterproof and anti-tightening bolts can be used to pass through the mounting through hole 550, the metal corrugated tile 100, and the roof purlin 200 in sequence to connect the first bracket 500, the metal corrugated tile 100, and the roof purlin 200 into a whole, thereby enhancing the overall stress capacity and strengthening the end face strength of the metal corrugated tile 100.

[0039] like Figure 5 As shown, in this embodiment, a plurality of metal corrugated tiles 100 form a color steel tile, and adjacent metal corrugated tiles 100 are interlocked together through the crests 110 to form a whole. When the first bracket 500 is fixed to the metal corrugated tile 100, the first cross-section 510 is pressed against the crests 110 at the interlocking position, further improving the interlocking strength of the crests 110. At the same time, the upper end of the first cross-section 510 can also be used to support the photovoltaic module 300, providing a support surface for placing the photovoltaic module 300.

[0040] Furthermore, the first supporting portion 520 is disposed at the end surface between the wave crests 110 of adjacent metal corrugated tiles 100. Since the first supporting portion 520 is square and its height is smaller than the first cross-section 510, a cooling bracket 400 can be placed between the first cross-section 510 and the photovoltaic module 300 to cool the photovoltaic module 300 and enhance the heat dissipation efficiency of the photovoltaic module 300. To increase the connection strength between the first bracket 500 and the metal corrugated tile 100, a first connecting portion 530 is provided between the first cross-section 510 and the first supporting portion 520. The first connecting portion 530 is bent toward the photovoltaic module 300, leaving a bonding gap between the first connecting portion 530 and the end surface of the metal corrugated tile 100. Structural adhesive is then placed in the bonding gap to bond the first connecting portion 530 to the metal corrugated tile 100.

[0041] like Figure 7 As shown, because the distance between the crests 110 of the metal corrugated tile 100 is greater than 15 cm, to further enhance the end surface strength of the metal corrugated tile 100, a second bracket 600 is provided between adjacent crests 110 on the metal corrugated tile 100. The second bracket 600 is arranged parallel to the second bracket 600 and is both arranged along the first direction. The second bracket 600 includes a second supporting portion 610 and a fastening portion 620 symmetrically arranged between the second supporting portions 610. The second supporting portion 610 is provided at the end surface between the crests 110 of adjacent metal corrugated tiles 100, and the fastening portion 620 is fastened to the crests 110 on both sides.

[0042] In order to jointly support the cooling bracket 400 with the first support portion 520, the second support portion 610 is aligned with the first support portion 520, and the heights of the first support portion 520 and the second support portion 610 are equal, so as to jointly support the cooling bracket 400, so that the cooling bracket 400 can be attached to the bottom of the photovoltaic component 300.

[0043] Similarly, in order to enhance the connection strength between the second bracket 600 and the metal corrugated tile 100, a second connecting portion 630 is provided between the second supporting portion 610 and the buckling portion 620. The second connecting portion 630 is bent toward the photovoltaic component 300, leaving a bonding gap between the second connecting portion 630 and the end face of the metal corrugated tile 100, and then a structural adhesive is placed in the bonding gap to bond the second connecting portion 630 and the metal corrugated tile 100.

[0044] Furthermore, because the metal corrugated tile 100 in this embodiment is diamond-shaped, when the second bracket 600 is bonded between the crests 110 of the metal corrugated tile 100, the fastening portions 620 on both sides fasten to the side of the crest 110 away from the second supporting portion 610. By staggering the second brackets 600 on both sides of the crest 110, the second brackets 600 are staggered and fastened to the two sides of the crest 110, avoiding the need for a punched connection method, ensuring the structural strength of the metal corrugated tile 100. At the same time, the contoured arrangement of the second bracket 600 and the metal corrugated tile 100 further strengthens the end surface strength of the metal corrugated tile 100. The fastening portions 620 and the second supporting portion 610 also have recessed receiving grooves 640 for receiving structural adhesive, thereby bonding to the bottom of the photovoltaic module 300.

[0045] In addition, the height of the buckling portion 620 is equal to the height of the first supporting portion 520 , so as to provide a plurality of supporting surfaces of equal height on the crest 110 of the metal corrugated tile 100 for connecting the photovoltaic assembly 300 .

[0046] like Figure 9 As shown, it should be emphasized that in order to increase the connection area with the bottom of the photovoltaic module 300, a third bracket 700 is provided along the second direction on the crest 110 of the metal corrugated tile 100. The third bracket 700 includes a support plane 710 and engaging inclined surfaces 720 symmetrically arranged on both sides of the support plane 710. The support plane 710 and the engaging inclined surfaces 720 enclose an engaging space. When the third bracket 700 is installed on the crest 110, the top of the crest 110 abuts against the bottom of the support plane 710, and the engaging inclined surfaces 720 abut against the bottom of the crest 110, so that the third bracket 700 and the crest 110 are tightly fitted, preventing relative movement between the third bracket 700 and the crest 110.

[0047] According to one aspect of the above technical solution, to connect the photovoltaic module 300, the support surface 710 is recessed with a snap-in groove 711 facing away from the photovoltaic module 300. The bottom of the snap-in groove 711 abuts against the crest 110 of the metal corrugated tile 100. The snap-in groove 711 presses against the crest 110 at the interlocking point, further enhancing the snap-in strength of the crest 110. Furthermore, because the support surface 710 is recessed with the snap-in groove 711, structural adhesive can be placed within the snap-in groove 711. When the photovoltaic module 300 is in use, the structural adhesive within the snap-in groove 711 effectively bonds the photovoltaic module 300 to the third bracket 700. Furthermore, because both the first supporting portion 520 and the second supporting portion 610 abut against the cooling bracket 400, structural adhesive can also be placed within the cooling bracket 400 to connect the photovoltaic module 300 and the third bracket 700, thereby enhancing the stability between the photovoltaic module 300 and the support mechanism.

[0048] Please refer to Figure 8In this embodiment, the photovoltaic module 300 uses a frameless substrate. When the photovoltaic module 300 is installed, a water retaining strip 800 is often set below the joints of adjacent photovoltaic modules 300. By using physical barriers, a continuous waterproof barrier is formed at the joints of adjacent photovoltaic modules 300 to prevent rainwater from directly invading the roof structure layer or indoor space from the board seams. Especially in a windy and rainy environment, the wind may cause rainwater to splash back, and the water retaining strip 800 can effectively resist the risk of such "wind-driven rain" infiltration. The water retaining strip 800 is usually fixedly connected to the cooling bracket 400, the second bracket 600, and the third bracket 700 by structural adhesive and self-tapping screws.

[0049] Based on the above structure, the cooling bracket 400, the first bracket 500, the second bracket 600, and the third bracket 700 form a horizontal plane. Structural adhesive is applied to the grooves of the cooling bracket 400, the second bracket 600, and the third bracket 700. The photovoltaic module 300 is then installed on the cooling bracket 400, the second bracket 600, and the third bracket 700. Structural adhesive is applied to the water retaining strip 800 at the joint between two adjacent photovoltaic modules 300 to prevent rainwater from seeping in.

[0050] In some other application scenarios, rock wool 900 can also be set between the supporting mechanism and the roof purlin 200. As a high-efficiency thermal insulation material, rock wool 900 can significantly reduce roof heat conduction. Rock wool 900 can act as an active thermal insulation layer to reduce the thermal bridge effect of the roof, so that the indoor air conditioning system does not need to be overly dependent on regulation, thereby reducing energy consumption costs. At the same time, the setting of rock wool 900 means that the supporting mechanism does not need to rely entirely on the roof purlin 200, and the requirements for structural design are lower. In high wind pressure areas, the amount of steel used can be effectively reduced, which is convenient for cost savings. In addition, the setting of rock wool 900 can also reduce external noise and improve the indoor living environment.

[0051] In summary, according to a metal roof BIPV support mechanism provided by the present invention, a hole is opened on the first supporting part, a first cross-part is arranged on the crest, the metal corrugated tile is connected to the roof purlin by fasteners, and the first bracket and the metal corrugated tile are bonded with structural adhesive, thereby reducing the number of holes and ensuring structural strength. At the same time, the first cross-part can also support the photovoltaic module; a second bracket is used to be set between the crests of adjacent metal corrugated tiles, and the two ends of the second bracket are buckled with the crests on both sides and bonded with structural adhesive. While fixing the second bracket, the strength of the end face of the metal corrugated tile is improved, and the second supporting part and the first supporting part are used to support the cooling bracket, which is then used to connect the photovoltaic module; the third bracket is clamped at the crest to provide a support plane for supporting the photovoltaic module, and forms a waterproof function of the building with the photovoltaic module. The present invention replaces the traditional installation method of using a mounting clamp to clamp on the crest, installing purlins on the clamp, and then fastening the purlins to the photovoltaic modules by arranging the first bracket, the second bracket, and the third bracket at the crest of the metal corrugated tile. This provides multiple support surfaces for installing photovoltaic modules, reduces hidden crack damage to the photovoltaic module cells caused by stepping on them, and improves the hail resistance of the photovoltaic modules; improves the ability of the metal corrugated tile to withstand wind pull, reduces the possibility of irreversible deformation or even tearing of the metal corrugated tile crest caused by the traditional clamp installation method, and avoids roof leaks and property losses.
