Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic brackets, and particularly relates to a photovoltaic bracket structure and an installation method thereof. Background Art

[0002] When installing a photovoltaic system on a tile roof, it is generally necessary to adopt an under-tile anchoring method, that is, to use a hook-shaped part with a continuous Z-shaped bend to form a rooting structure in the space below the tiles, and to extend through the overlapping gaps of the tiles by continuous Z-shaped bends to form a connection point for continued upward installation.

[0003] For this installation method, it is necessary to uncover or cut the tiles to expose the building structure layer below the tiles for anchoring. When uncovering the tiles, since the tiles overlap each other, it is often necessary to disassemble four or more adjacent tiles to achieve the above-mentioned effect of exposing the building structure under the tiles. This process of removing the tiles is very difficult, easily causing tile breakage, and because the tiles are often fixed with hanging tile screws, which are hidden in the overlapping gaps of the tiles, it is very difficult to disassemble. If the tiles are cut, the waterproof structure of the tiles will be damaged. After anchoring, it is necessary to re-bond or repair the cut part, but the repaired structure cannot achieve the original waterproof structure characteristics of the tiles, and it is very easy to leak water during subsequent operation.

[0004] In view of the above situation, in order to overcome the above technical problems, the present invention designs a photovoltaic bracket structure and an installation method thereof. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: by improving the anchoring bottom plate form of the hook part of the original Z-shaped bending plate and improving the design of the key installation required structural surface and angle to adapt to the installation method and characteristics of the nail gun, so that it can achieve effective anchoring without removing the tiles but only prying open at a small angle, greatly improving the efficiency of the anchoring process in the installation of photovoltaic on the roof, and further can significantly reduce the labor cost and effectively prevent damage to the structure during the construction process.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: A photovoltaic bracket structure and an installation method thereof provided by the present invention include a Z-shaped bending plate and a continuous bending part. The continuous bending part is installed on the Z-shaped bending plate. The Z-shaped bending plate makes the nail perpendicular to the installation surface and shoot into the roof plane through the positioning scale line. The nail head of the nail penetrates into the roof plane. The nails shot into from two installation surfaces are staggered and non-intersecting in space, and the nails can be locked with each other; in addition, structural materials are injected into the cavity below the triangular pyramid through the glue injection hole on the Z-shaped bending plate, which can not only further strengthen the overall fastening but also further lock the nails staggered in space with each other.

[0007] The Z-shaped bending plate includes a first bottom plate plane, a protruding piece, a first triangular pyramid mounting surface, a second triangular pyramid mounting surface, a second bottom plate plane, and a third bottom plate plane.

[0013] An installation method for a photovoltaic support includes: S1: First, according to the photovoltaic module layout diagram, determine the positions of the anchor points, uncover the tiles at a certain angle at the installation position and temporarily support and fix them. Considering that the tiles are hard materials, when uncovering the required tiles to the required angle, it is often necessary to also open the surrounding tiles at a small angle and temporarily support and fix them, but generally it is not necessary to uncover all the tiles. S2: Before installing the hook piece of the Z-shaped bending plate, blow the dust on the roof plane at its installation position. S3: Extend the hook of the Z-shaped bent plate under the tile gap at the required position. Considering the undulation of the tiles, find a suitable position, place the first bottom plate plane, the second bottom plate plane, and the third bottom plate plane on the roof plane under the tiles, and make the protruding pieces on the bottom plate plane insert under the lath for hanging tiles. Load the nail gun with nails, obliquely insert it into the opened gap of the tile, vertically press against the first triangular pyramid installation surface and the second triangular pyramid installation surface, and align the reserved installation holes through the positioning score lines.

S4: After all the nails are installed, inject structural materials through the glue injection holes to strengthen the overall fastening structure and also lock the nails staggered in space. S5: According to the characteristics of the tiles and the need for waterproofing, install the water guide plate through the water guide plate installation holes on the flat folding surface of the continuous folding piece, and make it clamped between the upper and lower tiles.

[0015] 2. It can be anchored using a nail gun, which has a significant improvement in efficacy compared to using expansion screws or chemical anchor bolts.

[0016] 3. The triangular pyramid installation surface formed by the second triangular pyramid installation surface, the second triangular pyramid installation surface, and the triangular pyramid weld surface can utilize the gap when the tile is lifted at a small angle to insert and fire the nail gun, avoiding the processes of removing and restoring the tile, and further improving the installation efficiency.

[0017] 4. The setting of the glue injection holes can further strengthen the fastening structure and protect the mutually locked structure by injecting structural glue or concrete on the mutually locked structure realized by the nails.

[0018] 5. The setting of the elastic piece structure can utilize the elastic stress and always apply it in a direction at a certain angle to the nail insertion direction to further strengthen the aforementioned mutually locked structure. And the opposite opening direction enables the elastic piece to strengthen the grasping force and anti-slip effect on the building contact surface, which is also a further strengthening of the aforementioned mutually locked structure.

[0019] 6. Near the near edge of the long strip hole, there is a protruding piece extending outward from the near edge, which is used to be inserted under the lath on the building, and can strengthen the structure.

[0020] 7. The bottom plate is formed by bending and welding a flat unfolded plane to form a three-dimensional structure of a triangular pyramid. The processing technology is simple and it is convenient to make small adjustments according to needs. The third surface except for the two installation surfaces is formed by splicing two parts in the unfolded plane, which can greatly reduce the blanking area of the unfolded plane.

[0021] 8. On the contact surface sandwiched between the upper and lower tiles in the Z-shaped connection bend, there are reserved threaded holes for fixing the water guide piece. The setting of the water guide piece can effectively fill the gap caused when the Z-shaped continuous bend extends out of the overlapping joint of the tiles, realize the guiding of water flow, and reduce the risk of roof leakage.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] like Figure 1 , 2 As shown in , 3, 4, 5 and 6, the present invention provides a photovoltaic support structure and installation method, including a Z-shaped bending plate 1 and a continuous bending part 2, the continuous bending part 2 is installed on the Z-shaped bending plate 1, the Z-shaped bending plate 1 allows nails 3 to be shot in perpendicular to the installation surface through the positioning mark 19, the nail heads of the nails 3 are inserted into the roof plane, and the self-tightening nails 3 shot from the two installation surfaces are staggered and non-intersecting in space, and the nails 3 can be locked with each other; in addition, the structural material is injected into the cavity below the triangular pyramid through the glue injection holes 131 on the Z-shaped bending plate 1, which can not only further strengthen the overall fastening, but also further lock the nails 3 staggered in space with each other.

[0027] Extend the hook of the Z-bend plate 1 to the gap of the tile 6 at the desired position, find a suitable position in combination with the ups and downs of the tile 6, place the bottom plate flat on the roof plane under the tile, and insert the protruding piece 12 on the bottom plate plane under the tile hanging strip 7. Install the nail gun with the nail 3, insert it obliquely into the gap opened by the tile 6, and press it against the first triangular pyramid mounting surface 13 and the second triangular pyramid mounting surface 14 vertically, and align the reserved mounting hole through the positioning score line 19, fire the gunpowder, so that the nail 3 is shot perpendicular to the mounting surface, the nail head is inserted into the roof plane, and the nails 3 shot from the two mounting surfaces are staggered in space without intersecting, so that the nails 3 can be locked with each other while they are tightened separately.

[0028] like Figure 1 , 4As shown in FIGS. 3 and 5, the Z-shaped bending plate 1 includes a first bottom plate plane 11, a protruding piece 12, a first triangular pyramid mounting surface 13, a second triangular pyramid mounting surface 14, a second bottom plate plane 16, and a third bottom plate plane 17. The first bottom plate plane 11 is mounted on the continuous bending piece 2, the protruding piece 12 is mounted on the first bottom plate plane 11, and a triangular pyramid composed of a first triangular pyramid mounting surface 13, a second triangular pyramid mounting surface 14, and a triangular pyramid weld surface 15 is fixedly mounted on both sides of the first bottom plate. A second bottom plate plane 16 and a third bottom plate plane 17 are fixedly mounted on the outer side of the triangular pyramid composed of the first triangular pyramid mounting surface 13, the second triangular pyramid mounting surface 14, and the triangular pyramid weld surface 15.

[0029] The bottom plate is formed by bending and welding an unfolded plane to form a three-dimensional structure of a triangular pyramid. The processing technology is simple and it is convenient to make small adjustments according to needs. Among them, the third surface except for the two mounting surfaces is formed by splicing two parts in the unfolded plane, which can greatly reduce the blanking area of the unfolded plane. And after all the nail guns 3 are installed, structural adhesive or thin concrete is injected into the cavity below the triangular pyramid through the glue injection hole 131 to strengthen the overall fastening structure, and it can also protect the nail guns 3 with staggered spaces and further lock them with each other to improve the reliability of the entire anchoring structure. In the case of adopting this glue injection process, the roof plane at the installation position should be cleaned of dust before installing the hook piece of the Z-shaped bending plate 1.

[0030] As Figure 1 、 4 As shown in FIGS. 3, 4 and 5, a long hole 111 for fixing the continuous bending piece 2 is provided on the first bottom plate plane 11, and one end of the long hole 111 is close to the protruding piece 12.

[0031] At the near side of the long hole 111, there is a protruding piece 12 extending outward from the near side, and this protruding piece 12 is used to be inserted below the batten 7 on the building, which can strengthen the structure.

[0032] As Figure 1 、 2 As shown in FIGS. 3, 4 and 5, a plurality of elastic pieces 18 are mounted on the first bottom plate plane 11, elastic pieces 18 are mounted on the second bottom plate plane 16 and the third bottom plate plane 17, and the opening directions of the elastic pieces 18 on the first bottom plate plane 11 are opposite to those of the elastic pieces 18 on the second bottom plate plane 16 and the third bottom plate plane 17.

[0033] On the bottom plate, a number of downward elastic pieces 18 are also formed by stamping. One side of each elastic piece 18 structure is connected to the bottom plate, and the opening directions of multiple elastic piece 18 structures are set to be opposite. Moreover, with the arrangement of the elastic piece 18 structure, elastic stress can be utilized to always apply in a direction at a certain angle to the insertion direction of the nail 3, further strengthening the aforementioned mutual locking structure. The opposite opening directions enable the elastic piece 18 to enhance the gripping force and anti-slip effect on the building contact surface, which is also a further strengthening of the aforementioned mutual locking structure.

[0034] As Figure 1 and 5 shown, a glue injection hole 131 is provided on the first triangular pyramid mounting surface 13. The structural material injected into the glue injection hole 131 is structural glue or thin concrete. And positioning scale lines 19 are installed on the first triangular pyramid mounting surface 13 and the second triangular pyramid mounting surface 14. A nail 3 is installed in the positioning scale line 19. The nails 3 are staggered and do not intersect in space, and the nail 3 is installed and fixed through the nail gun barrel 4 above.

[0035] Align the positioning scale line 19 with the reserved installation hole, fire the gunpowder, and through the nail gun barrel 4, make the nail 3 penetrate vertically into the mounting surface. The nail head inserts into the roof plane, and the nails 3 inserted from the two mounting surfaces are staggered and do not intersect in space. While achieving their respective fastening, the nails 3 can be mutually locked. After all the nails 3 are installed, inject structural glue or thin concrete into the cavity below the triangular pyramid through the glue injection hole 131 to strengthen the overall fastening structure, and also protect the nails 3 that are staggered in space and further mutually lock them, improving the reliability of the entire anchoring structure.

[0036] As Figure 1 、 2 、3, 4, 5 and 6 shown, a continuous bending piece 2 is installed in the long slot 111. A water guide plate installation hole 22 is provided on the flat folding surface 21 of the continuous bending piece 2. A water guide plate 5 is installed on the flat folding surface 21, and the water guide plate 5 and the flat folding surface 21 are connected by water guide plate installation screws 23. A photovoltaic bracket connection hole 24 is provided above the continuous bending piece 2.

[0037] The connection position between the long slot 111 on the first bottom plate plane 11 and the continuous bending piece 2 is not at the geometric center of the bottom plate, but is biased towards the upper side after the overlapping of the tiles 6 according to the overlapping method of the tiles 6, so as to cooperate with the other side to insert the nail gun under a smaller tile uncovering angle to achieve the fastening of the nail 3.

[0038] As Figure 1 、 2As shown in Figures 3, 5 and 6, tiles 6 are installed above and below the water guide plate 5, tile hanging strips 7 are installed below the tiles 6, photovoltaic mounting rails 8 are installed at the photovoltaic bracket connecting holes 24 on the continuous bending part 2, and the photovoltaic mounting rails 8 and the continuous bending part 2 are installed and fixed by rail mounting screws 9.

[0039] According to the characteristics of the tile 6 and the need for waterproofing, a water guide plate 5 can be optionally installed, which is fixed through the water guide plate mounting hole 22 on the flat folding surface 21 of the continuous bending part 2 and clamped between the upper and lower tiles 6 to achieve a water guide effect to enhance the waterproof effect.

[0040] like Figure 7 As shown, a method for installing a photovoltaic bracket includes: S1: First, determine the position of the anchor point according to the photovoltaic module layout diagram, and uncover the tile 6 at a certain angle at the installation position and temporarily support and fix it. Considering that the tile 6 is made of hard material, when uncovering the required tile 6 to the required angle, it is often necessary to open the surrounding tiles 6 at a smaller angle and temporarily support and fix them, but it is generally not necessary to uncover all the tiles 6; S2: Before installing the hook member of the Z-bent plate 1, the roof plane at the installation location is dust-blown; S3: Extend the hook of the Z-shaped bending plate 1 to the gap of the tile 6 at the desired position, find a suitable position in combination with the ups and downs of the tile 6, place the first bottom plate plane 11, the second bottom plate plane 16 and the third bottom plate plane 17 on the roof plane under the tile, and insert the protruding piece 12 on the bottom plate plane under the tile hanging strip 7, install the nail gun with the nail 3, insert it obliquely into the gap opened by the tile 6, vertically press against the first triangular pyramid mounting surface 13 and the second triangular pyramid mounting surface 14, and align the reserved mounting holes through the positioning engraved line 19, fire the gunpowder, so that the nail 3 is shot perpendicular to the mounting surface, the pointed end is inserted into the roof plane, and staggered in space without intersecting; S4: After all the nails 3 are installed, the structural material is injected through the glue injection hole 131 to strengthen the overall fastening structure and also to lock the nails 3 that are staggered in space; S5: According to the characteristics of the tile 6 and the need for waterproofing, the water guide plate 5 is installed through the water guide plate installation hole 22 on the flat folding surface 21 of the continuous bending member 2 so that it is sandwiched between the upper and lower tiles 6; S6: After the hooks of the Z-shaped bending plate 1 are installed, the temporary supports of the tiles 6 that were previously opened are removed to restore the original overlapping relationship and level them; S7: Install the photovoltaic bracket of the previous layer on the photovoltaic bracket connection hole 24 of the hook piece of the Z-shaped bending plate 1, which can be a purlin / guide rail or a leg, and further realize the installation of the photovoltaic system structure through these brackets.

[0041] During the working process of the present invention, the positions of the anchoring points are first determined according to the photovoltaic module layout diagram. At the installation position, the tiles 6 are lifted at a certain angle and temporarily supported and fixed. Considering that the tiles 6 are made of hard materials, when lifting the required tiles 6 to the required angle, it is often necessary to also open the surrounding tiles 6 at a small angle and temporarily support and fix them, but generally it is not necessary to remove all the tiles 6. Before installing the hook part of the Z-shaped bending plate 1, the roof plane at its installation position is purged of dust. The hook part of the Z-shaped bending plate 1 is extended under the gap of the tiles 6 at the required position. Combining with the undulation of the tiles 6, a suitable position is found, the bottom plate is placed flat on the roof plane under the tiles, and the protruding piece 12 on the bottom plate plane is inserted under the hanging tile strip 7. The nail gun is loaded with nails 3, obliquely inserted into the opened gap of the tiles 6, vertically against the first triangular cone installation surface 13 and the first triangular cone installation surface 14, and the reserved installation holes are aligned through the positioning scale line 19. The gunpowder is fired to make the nails 3 penetrate vertically into the installation surface, the pointed ends are inserted into the roof plane, and they are staggered and non-intersecting in space. While achieving their respective fastening, the nails 3 can be locked with each other. After all the nails 3 are installed, structural adhesive or thin concrete is injected through the glue injection hole 131 to strengthen the overall fastening structure, and it can also protect the nails 3 that are staggered in space and further lock them with each other, improving the reliability of the entire anchoring structure. According to the characteristics of the tiles 6 and the need for waterproofing, the water guide pieces are installed through the water guide piece installation holes 22 on the flat folding surface 21 of the continuous bending piece 2, and are clamped between the upper and lower tiles 6. After the hook part of the Z-shaped bending plate 1 is installed, the temporary support of the previously opened tiles 6 is removed, so that they are restored to their original overlapping relationship and arranged flat. On the photovoltaic bracket connection hole 24 of the hook part of the Z-shaped bending plate 1, the upper layer of photovoltaic brackets can be installed, which can be purlins / rails or legs, and through these brackets, the installation of the photovoltaic system structure is further realized.
