The integrated design of the two organically combines photovoltaic panels with metal roofing to maintain the integrity and aesthetics of the building's appearance, but this photovoltaic system has a high investment cost and is relatively limited in application. Therefore, a construction method for photovoltaic tiles composite colored stone metal tiles on sloping roofs that can both ensure the use function of the roofing project and meet the visual requirements is needed. Summary of the invention

[0003] The purpose of the present invention is to provide a construction method of photovoltaic tiles composite colored stone metal tiles on sloping roofs that can ensure the use function of roofing engineering and meet the requirements of appearance. This construction method utilizes the characteristics of colored stone metal tiles, such as strong durability, good aesthetics, light weight and high strength, easy installation, green environmental protection and good economy, to combine colored stone metal tiles and photovoltaic tiles into one, replacing traditional aluminum-magnesium-manganese plate metal roofs or metal tile roofs, forming a new roof system and construction technology of photovoltaic tiles composite colored stone metal tiles on sloping roofs, achieving the construction purpose of reducing costs and increasing efficiency.

[0004] To achieve the above object, the present invention adopts the following technical solution: A construction method of a photovoltaic tile composite colored stone metal tile for a sloping roof comprises the following steps: (1) Construction of waterproof layer and thermal insulation layer on the sloping roof, embedding of embedded parts and pouring of thermal insulation protective layer; (2) Install the tile keel components of the sloping roof; (3) After the installation of the sloping roof tile keel components is completed, the colored stone metal tiles and photovoltaic tiles are installed; (4) Perform roof lightning protection treatment on the photovoltaic tile area and the colored stone metal tile area, and complete the installation of the photovoltaic tile composite colored stone metal tile sloping roof system.

[0005] Before proceeding to step (1), the roof tiles are arranged to determine the layout and positioning of the keel. The standard photovoltaic tile is a rectangular plate with a size of 1508mm long * 420mm wide. According to the size of the photovoltaic tile, a square-shaped colored stone metal tile with the same width is selected. The standard size of the colored stone metal tile is 1340mm * 420mm. The thickness of the photovoltaic tile and the colored stone metal tile is ≥ 0.5mm. The staggered edge pressing method is adopted between photovoltaic tiles, between colored stone metal tiles, and between photovoltaic tiles and colored stone metal tiles. Along the drainage direction, the edge of each layer of roof tiles is pressed by 50mm. After pressing, each tile is exposed 370mm wide. Then the layout design is carried out with a module of 370mm spacing between tile hanging strips. The water-following strips are located at the bottom of the tile hanging strips, and the spacing between the water-following strips is 600mm.

[0006] After the roof tile layout design is completed, the embedded parts of the roof tiles are made before step (1). The embedded parts of the roof tiles are in the form of steel plate + anchor bar. A 150mm*150mm*8mm galvanized steel plate is used as the welding surface for fixing the keel. Four 12mm diameter and 165mm long steel bars are used as anchor bars and plug-welded with steel plate holes. A 50mm long short steel bar is welded to the end of the steel bar to increase the tensile strength of the embedded parts.

[0007] The specific operation process of step (1) is as follows: first, lay the extruded board insulation layer, and after the extruded board insulation layer is laid, locate and lay out the embedded parts, then insert the anchor bar end of the embedded parts into the extruded board insulation layer and adjust the positioning and elevation to reserve the thickness of the concrete insulation layer, so that the surface elevation of the embedded parts and the surface elevation of the concrete protective layer are consistent, then lay the steel mesh in the concrete protective layer, adjust the thickness of the protective layer of the steel mesh, and temporarily tie and fix the embedded parts anchor bar and the steel mesh to avoid the embedded parts from being offset during concrete pouring, and finally pour the concrete protective layer.

[0008] The control standards for the longitudinal and transverse spacing of embedded parts are: the longitudinal spacing is the same as the spacing of the downstream strips, the transverse spacing is 600mm, the longitudinal spacing is ≤2500mm, the concrete protection layer is 70mmC25 fine stone concrete, with a single-layer bidirectional steel mesh ∅6@150 inside, the seam is set at ≤6m, the seam width is 10mm, and the seam is filled with polyurethane sealant with a depth of 10mm.

[0009] The specific operation process of step (2) is as follows: first, clean the embedded parts, then measure and lay out the lines. When measuring and laying out the lines, lay out the ridge line and the gutter line to ensure that the angles on both sides of the sloping roof are straight, then adjust the embedded plate, then install and weld the square tube columns and check the weld quality and position deviation, then weld the main keel and install it. After the main keel is installed, weld the secondary keel and install it. Finally, check the welding quality of the main keel and the secondary keel and perform anti-rust spraying to complete the installation of the tile keel assembly; The secondary keel uses galvanized steel square tubes with specifications of 30*30*2mm. The standard spacing of the tile strips is consistent with the module of colored stone metal tiles and photovoltaic tiles, and the spacing is 370mm; the tile strips at the eaves are higher than those at other parts and use galvanized steel square tubes with specifications of 50*30*2mm. The spacing of the tile strips at the eaves is smaller than that of the tile strips at other parts; The main keel uses galvanized steel square tube water strips with specifications of 30*30*2mm, with a spacing of 600mm. The water strips are welded and fixed on the embedded plate through square tube columns. The square tube columns are used to adjust the elevation of the main keel. The square tube columns use galvanized square tubes of 30*50*2mm. When welding the main keel and the secondary keel, manual arc welding or carbon dioxide gas shielded welding is used. The welding current of manual arc welding is 130~160A, and the welding voltage is 18~22V; the welding current of carbon dioxide gas shielded welding is 220~280A, and the welding voltage is 24~30V.

[0010] The specific operation process of step (3) is as follows: first install the colored stone metal tiles at the eaves and the ridge of the roof, and set a fascia board at the eaves of the roof as the edge board for the eaves and the first row of colored stone metal tiles. First install the fascia board, and fix it with steel nails on the side. The upper end of the fascia board presses the first tile hanging strip at the bottom, and then install the colored stone metal tiles, and use self-tapping screws to fix the first row of colored stone metal tiles at the bottom together with the upper end of the fascia board on the tile hanging strip; install the gutter board at the closing of the ridge, and the clamp of the gutter board The angle corresponds to the gutter angle. Additional purlins for the gutter and additional purlins for the attached board are set between the first colored stone metal tile extending to both sides at the bottom of the gutter and the gutter board. The gutter board is located below the colored stone metal tile at the yin ridge. First, the additional purlins for the gutter and the additional purlins for the attached board are welded and fixed to the water-following strips. Then, the gutter board is fixed with self-tapping screws. Then, the attached board is set on the additional purlins for the attached board. Finally, the first row of colored stone metal tiles is installed on the attached board. Each row of colored stone metal tiles is installed in sequence from the yin ridge to the yang ridge. The upper row of colored stone metal tiles is connected to the adjacent row of colored stone metal tiles through the connecting hooks. The colored stone metal tiles are installed layer by layer along the sloping roof in the order from right to left and from bottom to top until they are installed at the junction of the photovoltaic tiles and the colored stone metal tiles. The photovoltaic tiles are installed in the upper row of colored stone metal tiles. First, the third fixing piece is fixed to the side wall of the tile hanging strip with self-tapping screws. The U-shaped notch of the third fixing piece is clamped on the end of the colored stone metal tile, and then the photovoltaic tile and the third fixing piece are connected. Then, the photovoltaic tiles are installed upward layer by layer. When installing photovoltaic tiles, first determine the photovoltaic tile installation hanging strip. The position of the hook is determined, and the installation hook is installed on the lower side of the photovoltaic tile. Two hooks and four installation screws are set on each photovoltaic tile. After determining the position of the installation hook, the installation hooks in the lowest row are laid out first. After the installation hooks of the entire row of photovoltaic tiles are laid out, the colored stone metal tiles on the right side of this row are installed. After the colored stone metal tiles on the right side are installed, the photovoltaic tiles are laid from right to left so that the photovoltaic tiles fall into the notches of the installation hooks; the left and right frames of the photovoltaic tiles are overlapped by fixed card slots, the upper frame overlaps the card slots, and the lower frame forms a water guide groove for diversion of roof water; Then, the colored stone metal tiles on the left side of the photovoltaic tiles are laid, and the colored stone metal tiles directly overlapped with the left and right sides of the photovoltaic tiles are fixed with self-tapping screws and tile hanging strips; after the installation of the entire row of photovoltaic tiles is completed, the next row is installed from bottom to top, and the overlap distance of the photovoltaic tiles in adjacent rows is 45-60mm. In this way, the photovoltaic tiles and the surrounding colored stone metal tiles are installed row by row from bottom to top until they are installed to the intersection of the colored stone metal tiles and the upper and lower rows of photovoltaic tiles. At the intersection, the fourth fixing piece is fixed to the side wall of the tile hanging strip with self-tapping screws. The U-shaped notch of the fourth fixing piece clamps the end of the photovoltaic tile to fix the photovoltaic tile. An additional purlin is set on the water strip to support the colored stone metal tiles, and the colored stone metal tiles are fixed to the additional purlin with external hexagonal self-tapping screws; Then continue to install the colored stone metal tiles row by row from bottom to top. When the colored stone metal tiles are installed to the ridge, they are disconnected from the ridge line and a row of ridge tiles are installed on the ridge. A ridge tile purlin is attached on both sides of the ridge tile as the ridge tile hanging strip. The ridge tile purlin is welded and fixed with the water-following strip. The ridge tile is made of the same material as the colored stone metal tiles. Then, when the roof tiles are installed to the junction with the wall, the flashing board and the roof attachment board are installed to facilitate the closing treatment at the wall root. Specifically, when the colored stone metal tiles are paved to the wall root, the roof attachment board is installed, and the colored stone metal tiles are fixed to the tile hanging strips together with the hexagonal self-tapping screws, and then the flashing board is installed. The lower part of the flashing board is inserted into the end of the roof attachment board, and the upper end is fixed to the side wall with cement steel nails, and the interface between the flashing board and the side wall is sealed with waterproof sealant; Then when installing the sloping eaves gable part of the roof tiles, set gable attachment plates on the side of the eaves and the top of the colored stone metal tiles. After all the colored stone metal tiles are installed, the sloping eaves gable plates are edge-sealed. The upper gable attachment plates are fixed to the end tile hanging strips together with the colored stone metal tiles through external hexagonal self-tapping screws, and the side gable attachment plates are fixed to the sloping eaves structure through cement steel nails. The steel nails are sealed with sealant, and finally the gable plates are inserted into the upper and side gable attachment plates to complete the fixation of the gable plates.

[0011] The specific process of step (4) is as follows: for the photovoltaic tile assembly, before installation, the connecting wires can be uniformly connected to the grounding holes on the photovoltaic tile frame. After installing a row of photovoltaic tiles, the ends of the connecting wires of this row of photovoltaic tiles are pulled out first, and at the same time, the ends of the connecting wires are connected to the right frame of the photovoltaic tiles at the overlapping position. Before installing the next row of photovoltaic tiles, check whether the connecting wires of the grounding holes at the two ends of the current row of photovoltaic tiles are connected. After confirming that they are connected, the next row of photovoltaic tiles can be installed. The upper and lower rows of photovoltaic tiles are connected by connecting wires, so that the frames of all rows of photovoltaic tiles are connected into a conductive path and a bus is led out, which is connected to the grounding flat iron, and the grounding flat iron is led to the ground; For the roof lightning protection treatment in the colored stone metal tile area, the original roof lightning grid or lightning rod is used to allow the colored stone metal tiles to directly contact the lower tile hanging strips, and the tile hanging strips and lightning down conductors are welded and fixed to directly serve as lightning arresters.

[0014] The present invention adopts photovoltaic tiles and colored stone metal tiles to form a roofing system. Compared with the roofing system formed by the traditional photovoltaic tiles and aluminum-magnesium-manganese plate metal roofs or matching metal tiles, in terms of raw material cost, the colored stone metal tiles have a simple production process and low mold opening cost, which can save about half of the raw material cost; in terms of installation difficulty, the construction difficulty is greatly reduced. Since the size of the colored stone metal tiles can be finalized and processed according to demand, and can be cut on site, the material is relatively soft, and the embossed shape increases its own flexibility and rigidity. On the one hand, it is convenient for on-site trimming, and on the other hand, it ensures that people will not deform when stepping on it. Conventional matching metal tiles can only be customized and cannot be cut on site, and the installation precision requirements are also high. Therefore, the application is more widely applicable and more economical.

[0015] The present invention ensures the overall appearance of the colored stone metal tile and the photovoltaic tile, reduces the exposure of the nail holes, strengthens the integrity of the roof system, effectively improves the anti-leakage function of the roof system, and optimizes the embedded parts connection nodes to ensure the waterproof effect and avoid the leakage risk caused by too many column waterproof closings. In addition, the closing difficulty of the present application is reduced, the complex process is reduced, and the engineering quality is guaranteed.

[0016] The embedded parts of the present invention are embedded in the insulation layer and concrete protective layer of the inclined roof, replacing the traditional embedded parts embedded in the roof structure board. Since it does not pass through the roof waterproof layer, it does not damage the original waterproof system of the roof. At the same time, the anchor bars of the embedded parts are connected and fixed with the steel mesh in the concrete protective layer, which increases the tensile strength of the embedded parts. The embedded parts anchor claws are directly inserted into the extruded insulation board by the method of parallel reinforcement. Through the temporary fixation of the insulation board and the anchor claws, it is convenient to adjust the elevation of the embedded parts, ensuring the accurate positioning of the embedded parts.

[0017] The present invention arranges the keels of the colored stone metal tiles and photovoltaic tiles in advance, arranges the overall layout according to the size of the tiles, and the tile hanging strips and water-following strips refer to the arrangement of the primary and secondary keels of the steel structure. The main keel is welded through the columns and embedded parts, and the secondary keel is arranged according to the tile layout to adjust the spacing.

[0018] This application further arranges colored stone metal tiles around the photovoltaic tiles, which is convenient for closing and has beautiful shape. The joints of photovoltaic tiles and colored stone metal tiles are arranged in the direction of water flow on the sloping roof, and the photovoltaic tiles are designed with flush edges, the surrounding metal tiles are closed, and the joints in the same row are sealed with sealant to ensure the overall visual quality.

[0019] The present application utilizes the same color stone metal tile material to be processed into eaves boards, ridge tiles, gutter boards, flashing boards, gable boards and other edge boards, and uses 0.6mm thick stainless steel plates to be bent to form corresponding attached plates, which are used as waterproof sealing methods for sloping eaves and flashing boards, gutter boards and other edge boards. The attached plate buckles are used to clamp the edge boards, and there is no need to nail tile nails on the top of the edge boards, which solves the hidden danger of roof tile leakage that is prone to occur when nails are used to seal the edges in traditional construction.

[0038] Before proceeding to step (1), layout the roof tiles to determine the layout and positioning of the keels, design the layout of the photovoltaic tiles 9 and the colored stone metal tiles 8 in advance, and layout and position the installation keels. According to the sizes of the standard photovoltaic tiles 9 and the colored stone metal tiles 8, determine the layout method of the two and the module of the keel arrangement. The standard photovoltaic tile 9 is a rectangle with a size of 1508mm long * 420mm wide. According to the size of the photovoltaic tile 9, a square colored stone metal tile 8 of the same width is selected. The standard size of the colored stone metal tile 8 is 1340mm * 420mm. The thickness of the photovoltaic tile 9 and the colored stone metal tile 8 are both ≥ 0.5mm; In order to ensure the drainage requirements of the sloping roof, the staggered edge pressing method is adopted between the photovoltaic tiles 9, between the colored stone metal tiles 8, and between the photovoltaic tiles 9 and the colored stone metal tiles 8. Along the drainage direction, the edge of each layer of roof tiles is pressed by 50mm. After pressing, each tile is exposed 370mm wide. Then, the layout design is carried out with a module of 370mm spacing between the tile hanging strips 6 keels. The water-following strips 5 are located at the lower part of the tile hanging strips 6, and the spacing between the water-following strips 5 is 600mm.

[0039] After the roof tile layout design is completed, the roof tile embedded part 2 is manufactured before step (1). The roof tile embedded part 2 is in the form of steel plate + anchor bar. A 150mm*150mm*8mm galvanized steel plate is used as the welding surface for fixing the keel. Four 12mm diameter and 165mm long steel bars are used as anchor bars and plug-welded with the steel plate. A 50mm long short steel bar is welded to the end of the steel bar to increase the tensile strength of the embedded part 2.

[0040] The specific operation process of step (1) is as follows: the embedded part 2 is temporarily positioned and fixed to the extruded board insulation layer 1 in the sloping roof building structure design. The thickness of the extruded board is selected according to the energy-saving design requirements. The extruded board insulation layer 1 is first laid, and after the extruded board insulation layer 1 is laid, the position of the embedded part 2 is positioned and laid out, and then the anchor end of the embedded part 2 is inserted into the extruded board insulation layer 1 and the positioning and elevation are adjusted to reserve the thickness of the concrete insulation layer 3, so that the surface elevation of the embedded part 2 and the surface elevation of the concrete protective layer are consistent, and then the steel mesh 4 in the concrete protective layer is laid, the thickness of the protective layer of the steel mesh 4 is adjusted, and the anchor bar of the embedded part 2 and the steel mesh 4 are temporarily tied and fixed to avoid the embedded part 2 from being offset during concrete pouring, and finally the concrete protective layer is poured.

[0041] The control standards for the longitudinal and transverse spacing of embedded parts 2 are: the longitudinal spacing is the same as the spacing of downstream strips 5, the transverse spacing is 600mm, the longitudinal spacing is ≤2500mm, the concrete protection layer is made of 70mmC25 fine stone concrete, with a single-layer bidirectional steel mesh ∅6@150 inside, the seam is set at ≤6m, the seam width is 10mm, and the seam is filled with polyurethane sealant with a depth of 10mm.

[0042] The specific operation process of step (2) is as follows: first, the embedded parts 2 are cleaned, and then the measurement and laying out are performed. When measuring and laying out, the ridge line and the gutter line are laid out to ensure that the angles on both sides of the sloping roof are straight, and then the embedded plate is adjusted, and then the square tube column 7 is installed and welded, and the weld quality and position deviation are checked, and then the main keel is welded and installed. After the main keel is installed, the secondary keel is welded and installed, and finally the welding quality of the main keel and the secondary keel is checked and anti-rust paint is performed to complete the installation of the tile keel assembly; The secondary keel uses galvanized steel square tubes with specifications of 30*30*2mm for hanging tile strips 6. The standard spacing of the hanging tile strips 6 is consistent with the module of the colored stone metal tile 8 and the photovoltaic tile 9, and the spacing is 370mm; the height of the hanging tile strips 6 at the eaves is greater than the hanging tile strips 6 at other parts and uses galvanized steel square tubes with specifications of 50*30*2mm. The spacing of the hanging tile strips 6 at the eaves is smaller than that of the hanging tile strips 6 at other parts; The main keel uses galvanized steel square water strips 5 with specifications of 30*30*2mm, with a spacing of 600mm. The water strips 5 are welded and fixed on the embedded plate through square columns 7. The square columns 7 are used to adjust the elevation of the main keel. The square columns 7 use galvanized square tubes of 30*50*2mm. When welding the main keel and the secondary keel, manual arc welding or carbon dioxide gas shielded welding is used. The welding current of manual arc welding is 130~160A, and the welding voltage is 18~22V; the welding current of carbon dioxide gas shielded welding is 220~280A, and the welding voltage is 24~30V.

First install the fascia board 18, and fix it with steel nails on the side. The upper end of the fascia board 18 presses the first tile hanging strip 6 at the bottom, and then install the colored stone metal tiles 8, and use self-tapping screws to fix the first row of colored stone metal tiles 8 at the bottom together with the upper end of the fascia board 18 on the tile hanging strip 6; install the gutter board 10 at the closing of the ridge, and the angle of the gutter board 10 corresponds to The gutter angle is set between the first colored stone metal tile 8 extending to both sides from the bottom of the gutter and the gutter board 10. The gutter board 10 is located below the colored stone metal tile 8 at the ridge. The gutter additional purlin 11 and the attached board additional purlin 12 are first welded and fixed to the water-following strip 5, and then the gutter board 10 is fixed with self-tapping screws. Then, the attached board 13 is set on the attached board additional purlin 12, and finally, the first row of colored stone metal tiles 8 is installed on the attached board 13. Each row of colored stone metal tiles 8 is installed in sequence from the ridge to the ridge. The upper row of colored stone metal tiles 8 is connected to the adjacent row of colored stone metal tiles 8 by connecting hooks, and the colored stone metal tiles 8 are installed layer by layer along the sloping roof in the order from right to left and from bottom to top until they are installed at the junction of the photovoltaic tiles 9 and the colored stone metal tiles 8.

[0047] The present invention adopts photovoltaic tiles 9 and colored stone metal tiles 8 to form a roofing system. Compared with the roofing system formed by the traditional photovoltaic tiles 9 and aluminum-magnesium-manganese plate metal roof or matching metal tiles, in terms of raw material cost, the colored stone metal tiles 8 have a simple production process and low mold opening cost, which can save about half of the raw material cost; in terms of installation difficulty, the construction difficulty is greatly reduced, because the size of the colored stone metal tiles 8 can be finalized and processed according to demand, and can also be cut on site. Its material is relatively soft, and its flexibility and rigidity are increased by the embossed shape. On the one hand, it is convenient for on-site trimming, and on the other hand, it ensures that it will not be deformed when stepped on by people. Conventional matching metal tiles can only be customized and cannot be cut on site, and the installation precision requirements are also high. Therefore, the application of this application is more widely applicable and more economical.

[0048] The present invention ensures the overall appearance of the colored stone metal tile 8 and the photovoltaic tile 9, reduces the exposure of the nail holes, strengthens the integrity of the roof system, effectively improves the anti-leakage function of the roof system, and optimizes the connection nodes of the embedded parts 2 to ensure the waterproof effect and avoid the leakage risk caused by too many column waterproof closings. In addition, the closing difficulty of the present application is reduced, the complex process is reduced, and the engineering quality is guaranteed.

[0049] The embedded part 2 of the present invention is embedded in the insulation layer of the inclined roof and the concrete protective layer, replacing the traditional embedded part 2 embedded in the roof structure board. Since it does not pass through the roof waterproof layer, it does not damage the original waterproof system of the roof. At the same time, the anchor bar of the embedded part 2 is connected and fixed with the steel mesh 4 in the concrete protective layer, which increases the tensile strength of the embedded part 2. The embedded part anchor claw adopts the method of parallel reinforcement and is directly inserted into the extruded insulation board. Through the temporary fixation of the insulation board and the anchor claw, it is convenient to adjust the elevation of the embedded part 2, ensuring the accurate positioning of the embedded part 2.

[0050] The present invention arranges the keels of the colored stone metal tiles 8 and the photovoltaic tiles 9 in advance, and arranges the overall layout according to the size of the tiles. The tile hanging strips 6 and the water-following strips 5 refer to the arrangement of the primary and secondary keels of the steel structure. The main keel is welded through the columns and the embedded parts 2, and the secondary keel is arranged according to the tile layout to adjust the spacing.

[0051] The present application further arranges the colored stone metal tiles 8 around the photovoltaic tiles 9, which is convenient for closing and has beautiful shape. The joints of the photovoltaic tiles 9 and the colored stone metal tiles 8 are arranged in a way of overlapping in the direction of water flow on the sloping roof. In addition, the photovoltaic tiles 9 are designed to be flush with the edges, the surrounding metal tiles are closed, and the joints in the same row are sealed with sealant to ensure the overall visual quality.

[0052] The present application utilizes the same colored stone metal tile 8 material to be processed into eaves panels 18, ridge tiles 14, gutter panels 10, flashing panels 17, gable panels 19 and other edge panels, and uses 0.6mm thick stainless steel plates to be bent to form corresponding attached panels, which are used as waterproof sealing methods for inclined eaves and flashing panels 17, gutter panels 10 and other edge panels. The attached panel buckles are used to clamp the edge panels, and there is no need to nail tile nails on the top of the edge panels, which solves the hidden danger of roof tile leakage that is prone to occur when nails are used to seal the edges in traditional construction.
