[0002] Using the top area of ​​the building to build a solar thermal collection project, the sunlight is not blocked and does not occupy construction land, which has both economic and social benefits. However, for the construction of solar collectors on tiled sloping roofs, the traditional process is to reserve reinforced concrete piers as the installation foundation of solar collectors during the construction of the sloping roof structure. However, this reserved reinforced concrete pier makes the roof structure complicated, the number of detailed nodes in the roof waterproofing layer increases, the processing is difficult, and there is a risk of leakage. At the same time, the subsequent tile construction becomes more difficult. This drawback seriously restricts the development of the industry. Summary of the invention

[0003] The purpose of the present invention is to provide a sloping roof tile hanging structure with solar panel support and a construction method thereof; a steel frame structure is used to replace the reserved reinforced concrete pier, so that the solar collector on the sloping roof with tiles can be installed more firmly and waterproof more simply.

[0004] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is: a sloping roof tile hanging structure with solar panel support, including a building roof concrete structure sloping panel, on which a waterproof layer, a thermal insulation layer, a corrugated waterproof board and roof tiles are laid in sequence, and a tile hanging grid formed by transverse tile hanging steel bars of equal height is arranged on the corrugated waterproof board, and the roof tiles are arranged horizontally and vertically and overlapped and hung on the transverse tile hanging steel bars of the grid, and the solar panel is fixed on the roof tile through a supporting mounting frame, wherein upright upright steel bars are arranged on the sloping panel, and the upright steel bars are implanted and fixed on the sloping panel by drilling holes on the sloping panel, and the upright steel bars are inserted from the waterproof layer, the thermal insulation layer, the corrugated waterproof board and the roof tiles. The shaped waterproof board is passed through, and the transverse tile hanging steel bars of the tile hanging grid are welded and fixed on the vertical steel bars that pass through. The support and mounting frame includes multiple longitudinal beams for fixing the solar panels. The longitudinal beams are supported and fixed on the transverse tile hanging steel bars through connecting pieces. The connecting pieces include two angle steels arranged transversely and vertically. The two angle steels are connected by a strip-shaped connecting plate. The transverse angle steel of the connecting piece is connected and fixed to the transverse tile hanging steel bars. The connecting plate is placed under the roof tiles from the side of the rear end transverse angle steel, and the front end of the connecting plate extends out from the overlapping ends of the two roof tiles overlapped front and back. The vertical angle steel is arranged at the extending end of the front end of the connecting plate, and the longitudinal beams of the solar panel support and mounting frame are fixed on the vertical angle steels.

[0005] A further solution is that the penetration points of the upright steel bars through the waterproof layer, the thermal insulation layer and the corrugated waterproof board are sealed with asphalt paste for waterproofing.

[0006] A further solution is that the upright steel bars are threaded steel bars with a diameter not less than 12 mm.

[0007] A further solution is that the transverse tile hanging steel bars are angle steels, channel steels or square steel tubes, and the transverse angle steels of the connecting pieces are connected and fixed to the angle steels, channel steels or square steel tubes by screws.

[0008] A further solution is that oblique scissor-type supports are arranged between the longitudinal beams of the support mounting frame to reinforce and prevent deformation.

[0009] A construction method based on the sloping roof tile hanging structure with solar panel support, comprising laying a waterproof layer, a thermal insulation layer, a corrugated waterproof board and roof tiles in sequence on the sloping panel of the concrete structure of the building roof, the roof tiles are arranged horizontally and vertically and overlapped and hung on the transverse tile hanging steel bars of the tile hanging grid, the solar panels are fixed on the roof tiles through a support mounting frame, the support mounting frame comprises a plurality of longitudinal beams for fixing the solar panels, wherein the longitudinal beams are supported and fixed on the transverse tile hanging steel bars through connectors, after the waterproof layer is laid, the reinforcement for supporting the transverse tile hanging steel strips is firstly planted, the vertical reinforcement is implanted into the concrete structure sloping panel, and after the reinforcement is planted, the waterproof layer, thermal insulation layer, corrugated waterproof board and roof tiles are laid. A temperature layer and a corrugated waterproof sheet are provided. After the corrugated waterproof sheet is laid, transverse tile-hanging steel bars are welded on the protruding upright steel bars to form a tile-hanging grid. The connecting pieces of the solar panel support and mounting frame are positioned and fixed on the transverse tile-hanging steel bars of the tile-hanging grid. Then the roof tiles are laid. The connecting pieces include two angle steels arranged transversely and vertically. The two angle steels are connected by a strip connecting plate. The transverse angle steel of the connecting piece is connected and fixed to the transverse tile-hanging steel bars. The laid roof tiles cover the connecting plate from the side of the rear end transverse angle steel. The front end of the connecting plate extends from the overlapping ends of the two roof tiles overlapped front and back. The vertical angle steel is arranged at the protruding end of the front end of the connecting plate. The longitudinal beam is fixed on the vertical angle steel to form a solar panel support and mounting frame.

[0010] The plan is further as follows: determine the location of the rebar in the direction perpendicular to the ridge on the surface of the waterproof layer according to the model of the roof tiles, use a drill bit with the same diameter as the vertical steel bars to drill holes for the rebar according to the location of the rebar, the holes for the rebar extend into the concrete structure slope panel with a depth greater than 80mm, clean the dust in the hole with an air pump after drilling, inject asphalt paste and immediately insert the vertical steel bars painted with anti-rust paint. The vertical steel bars are threaded steel bars with a diameter of not less than 12mm. During the rebar planting process, rotate and insert in a single direction until the specified depth is reached, and use asphalt paste to perform node waterproofing on the points where the vertical steel bars pass through the waterproof layer.

[0011] The plan is to clean the surface of the sloping roof structure layer before laying the waterproof layer, then use at least 20mm thick DS mortar to level it, make the angular structure on the sloping roof into an arc, and then apply the waterproof layer primer. After the primer solvent evaporates, make an additional waterproof layer on the weak waterproof parts of the flue and exhaust pipe on the sloping roof. The edge width of the additional waterproof layer shall not be less than 250mm, and it shall be returned by not less than 450mm along the protrusions on the roof of the flue and exhaust pipe.

[0012] The plan is further as follows: the overlap of the corrugated waterproof board in the downstream direction is ≥100mm, and the transverse overlap shall not be less than a complete wave crest; the upper and lower rows of longitudinal overlap seams of the corrugated waterproof board are staggered by 1 / 3-1 / 2 of the width, and the vertical steel bars pass through the damage points of the corrugated waterproof board to carry out node waterproofing treatment with asphalt paste.

[0013] The solution is further as follows: the insulation layer is paved with insulation boards, adjacent boards are spliced ​​with staggered seams, and the gaps between the boards are densely filled with similar materials.

[0014] The beneficial effects of the present invention are: using embedded steel bars to fix galvanized steel transverse tile-hanging steel bars, and then using connecting parts to connect the solar mounting frame and the transverse tile-hanging steel bars, eliminating the reinforced concrete foundation pier in the traditional process, making the installation more firm and waterproofing simpler.

[0015] The use of this construction method avoids the situation in which the traditional installation process, when constructing the slope roof structure board, requires the reservation of reinforced concrete foundation piers, the cumbersome construction process, the difficulty of positioning, and the inability to effectively close the waterproofing.

[0016] This construction method gives priority to waterproofing node treatment, and will not cause leakage risks in the roof waterproofing layer due to the waterproofing nodes of the concrete foundation pier. The solar steel frame is easy and quick to install, while reducing the workload of the concrete foundation pier, waterproof additional layer and waterproofing node, speeding up the construction progress. After the rainy season test, the anti-leakage effect is significant compared with the traditional process, and it can be promoted on a large scale.

After the waterproof layer is laid, the reinforcement for supporting the transverse tile steel strips is firstly planted, and the vertical steel bars are implanted into the sloping panel of the concrete structure. After the reinforcement is planted, a waterproof layer, an insulation layer and a corrugated waterproof board are laid. After the corrugated waterproof board is laid, transverse tile-hanging steel bars are welded on the protruding upright steel bars to form a tile-hanging grid. The connecting pieces of the solar panel support and mounting frame are positioned and fixed on the transverse tile-hanging steel bars of the tile-hanging grid, and then the roof tiles are laid. The connecting pieces include two angle steels arranged transversely and vertically. The two angle steels are connected by a strip connecting plate. The transverse angle steel of the connecting piece is connected and fixed to the transverse tile-hanging steel bars. The laid roof tiles cover the connecting plate from the rear end transverse angle steel side. The front end of the connecting plate extends from the overlapping ends of the two roof tiles overlapped front and back. The vertical angle steel is arranged at the protruding end of the front end of the connecting plate. The longitudinal beam is fixed on the vertical angle steel to form a solar panel support and mounting frame.

[0029] Determine the location of the rebar in the direction perpendicular to the ridge on the surface of the waterproof layer according to the model of the roof tiles, use a drill bit with the same diameter as the vertical steel bars to drill holes for the rebar at the location, the holes extend into the concrete structure slope panel with a depth greater than 80mm, clean the dust in the hole with an air pump after drilling, inject asphalt paste and immediately insert the vertical steel bars painted with anti-rust paint. The vertical steel bars are threaded steel bars with a diameter of not less than 12mm. During the rebar planting process, rotate and insert in a single direction until the specified depth is reached. Use asphalt paste to perform node waterproofing on the point where the vertical steel bars pass through the waterproof layer.

[0030] Before laying the waterproof layer, first clean the surface of the sloping roof structure layer, then use at least 20mm thick DS mortar to level it, and make the angular structure on the sloping roof into an arc, and then apply the waterproof layer primer. After the primer solvent evaporates, make an additional waterproof layer on the weak waterproof parts of the flue and exhaust pipe on the sloping roof. The side width of the additional waterproof layer shall not be less than 250mm, and it shall be returned not less than 450mm along the protrusions on the roof of the flue and exhaust pipe.

[0031] The overlap of the corrugated waterproof board in the direction of water flow shall be ≥100mm, and the transverse overlap shall not be less than a complete wave crest; the upper and lower rows of longitudinal overlap seams of the corrugated waterproof board are staggered by 1 / 3-1 / 2 of the width, and the vertical steel bars pass through the damage points of the corrugated waterproof board to carry out node waterproofing treatment with asphalt paste.

[0032] The thermal insulation layer is paved with thermal insulation boards, adjacent boards are spliced ​​with staggered seams, and the gaps between the boards are densely filled with the same material.

[0033] The specific construction method steps are:

[0034] The first step is foundation construction: first clean the surface of the sloping roof structure layer, then use 20mm thick DS mortar to level it, and make the corner structure on the sloping roof into an arc;

[0035] The second step is waterproof layer construction: first apply the waterproof layer primer, wait for the primer solvent to evaporate, and then make a waterproof additional layer on the slope roof flue, exhaust pipe and other weak waterproof places. The side width of each waterproof additional layer should not be less than 250mm, and the return along the flue, exhaust pipe and other roof protrusions should not be less than 450mm; finally, lay a 4mm thick self-adhesive waterproof membrane;

The distance between two adjacent rebar locations parallel to the ridge should not exceed 800mm.

[0037] The fourth step is anchoring: use a drill bit with the same diameter as the anchoring bar to drill anchoring holes according to the layout position. The anchoring bar holes extend into the structural layer concrete with a depth greater than 80mm. After drilling, use an air pump to clean the dust in the hole. After injecting the anchoring glue, immediately insert the anchoring bar painted with anti-rust paint. During the anchoring process, rotate and insert in a single direction until the specified depth is reached. Use asphalt paste to treat the node at the damage point where the anchoring bar passes through the waterproof layer.

[0038] The fifth step is to install the insulation board: the roof insulation board should be laid with the point-frame method, the insulation layer should be laid flat, the adjacent boards should be staggered, and the gaps between the boards should be filled tightly with the same material.

[0039] Step 6: Install corrugated waterproof boards: The corrugated waterproof boards are laid from the eaves to the ridge. The bottom row of corrugated waterproof boards are stretched through the line and extended into the eaves 40~50mm. The ridge, gutter and other parts are closed with self-adhesive waterproof membranes with a width of 600mm and 300mm on each side. The pipes, smoke and air ducts, and the roots of the walls are 250mm above the finished surface of the building. The flat laying width is 250mm. The waterproof position is damaged to make waterproof detail node processing;

[0040] Step 7: Install the transverse tile-hanging steel bars: The transverse tile-hanging steel bars are installed parallel to the ridge direction and fully welded to the pre-buried reinforcement bars. The welds are polished and painted with anti-rust paint. After the installation is completed, scissor-type supports are made between the transverse tile-hanging steel bars of the parallel installation steel frame foundation:

[0041] Step 8, upper connector: The spacing of the connector parallel to the ridge and perpendicular to the ridge is determined according to the specifications of the solar system unit. The transverse angle steel of the connector is placed on the galvanized steel transverse tile-hanging steel bar. A rubber pad is added to the gap between the angle steel and the transverse tile-hanging steel bar, and then fixed with self-tapping screws and the transverse tile-hanging steel bar.

[0044] Part 11: Set scissor braces between the mounting frames. The scissor braces are made of 4mm thick galvanized flat steel. The width of the scissor braces is 2-3m, and one is set every 6-8m in the longitudinal distance. The connection between the scissor braces and the mounting frames is fully welded.

[0045] Step 12: Install the solar collector and its pipes.

[0046] in:

[0047] Steps 1 to 5 are the construction of the slope roof base.

[0048] In step 2, the thickness of DS mortar is not more than 20mm, and the internal and external corners of the flue and exhaust pipe on the roof are rounded; the additional waterproof layer in step 4 is set at the edge of the slope roof, the ridge, the connection between the slope roof and the flue and exhaust pipe, and the outer edge of the flue, and the width of the additional waterproof layer is not less than 250mm; in step 5, the thickness of SBS modified asphalt waterproof membrane is not less than 4mm. The structural layer, leveling layer, and waterproof layer must be constructed according to the specifications and accepted before the next process can be carried out.

[0049] Precise positioning, laying out and planting of reinforcement in step 6: When hanging tiles, it is necessary to construct from a low elevation upwards. The spacing of the horizontal tile hanging reinforcement in the vertical ridge direction is determined by the specifications of the roof tiles. The planting reinforcement must pass through the crest of the corrugated waterproof board, and the spacing parallel to the ridge direction is not more than 800mm; according to the above construction principles, the specifications and dimensions of the roof tiles and corrugated waterproof boards, the specific location of the planting reinforcement is determined, so as to perform precise positioning and laying out; the steps of planting reinforcement include:

[0050] 1. The drilling depth of the rebar planting hole should be ≥8cm. After drilling, the dust in the hole must be cleaned with an air pump, and the next construction process can only be carried out after ensuring the hole diameter, hole depth and dust-free inside the hole.

[0051] 2. After the embedded reinforcement is processed, it must be painted with anti-rust paint for rust prevention.

[0052] 3. After injecting the rebar glue, insert the rebar immediately, rotating and inserting in a single direction until it reaches the specified depth.

[0053] 4. A pull-out test shall be carried out 72 hours after the rebar is planted. The next construction process can only be carried out after the test result is qualified.

[0054] 5. When the rebar passes through the waterproof layer, the roots of the rebar should be treated with asphalt paste. The surface of the asphalt paste should be full, smooth and free of cracks.

[0055] 6. Water spray test: After the waterproof joints are treated, conduct a continuous water spray test for two hours, then observe the indoor ceiling, and only proceed to the next step if there is no leakage.

[0056] Detailed explanation of step 7: Insulation layer construction, roof insulation board laying should be pasted using the point frame method, the insulation layer should be laid flat, adjacent boards should be staggered, and the gaps between boards should be filled with the same material;

[0057] Laying of corrugated waterproof sheet and waterproof membrane of waterproof layer:

[0058] 1. Lay the corrugated waterproof board from the eaves gutter toward the ridge, and draw a line through the bottom row of corrugated waterproof boards to ensure that they are straight and extend 40-50mm into the eaves gutter.

[0059] 2. The overlap of the corrugated waterproof board in the direction of water flow shall be ≥100mm, and the horizontal overlap shall not be less than a complete wave crest. The vertical overlap seams of the upper and lower rows shall be staggered by 1 / 3-1 / 2 of the width, and shall not be made into a continuous seam.

[0060] 3. When laying the waterproof board to the gutter, pull the wire along the direction of the gutter and cut it with a cutting machine to ensure the straightness of the cut section.

[0061] 4. When laying the corrugated waterproof board, pre-layout should be carried out to determine the punching position at the crest of the wave, and the holes should be slightly larger than the diameter of the steel bar.

[0062] 5. Self-adhesive waterproof membrane is used to seal the ridge, gutter and other parts, with a width of 600mm and 300mm on each side.

[0064] 7. When the embedded reinforcement passes through the crest of the corrugated waterproof board, if the gap width is ≤3mm, directly seal it with weather-resistant sealant; if the gap width is greater than 3mm, first fill it with foam glue and then seal it with weather-resistant sealant.

[0065] Steps 8 to 12 are described in detail. The transverse tile-hanging steel bars are galvanized steel transverse tile-hanging steel bars. The process of installing the galvanized steel transverse tile-hanging steel bars and the solar mounting frame includes:

[0066] 1. Install galvanized steel transverse tile-hanging steel bars. The transverse tile-hanging steel bars are parallel to the ridge direction. The spacing between the transverse tile-hanging steel bars is the longitudinal length of the roof tile minus the lap length of the upper and lower tiles.

[0067] 2. The exposed ends of the transverse tile-hanging steel bars and the embedded bars are fully welded, the welds are polished and painted with anti-rust paint.

[0068] 3. After the installation is completed, the transverse tile-hanging steel bars are parallel in the longitudinal direction and do not form a lattice system. It is necessary to make scissors struts between the parallel installed transverse tile-hanging steel bars. The scissors struts are made of 4mm thick galvanized flat steel, with a width of 2-3m and a longitudinal spacing of 6-8m. The scissors struts and the transverse tile-hanging steel bars are fully welded and fixed, the welds are full and uniform, and anti-rust paint is applied.

[0069] 4. Upper connector. The connector is welded by 50*30*5mm galvanized angle steel and 50*5mm thick flat steel. The welds must be polished and painted with anti-rust paint. The specifications and dimensions of the connector are determined according to the specifications of the roof tiles. Four bolt holes are opened at the connection between the connector and the transverse tile-hanging steel bar. The hole diameter is 8mm, the hole spacing is 80mm, and the end hole position is 20mm away from the edge. The spacing of the connector parallel to the ridge direction and perpendicular to the ridge direction is determined according to the specifications of the solar system unit. The transverse angle steel of the connector is placed on the galvanized steel transverse tile-hanging steel bar. A rubber pad is added to the gap between the angle steel and the transverse tile-hanging steel bar, and then 4 self-tapping screws (M4.8*40) are used to fix it with the transverse tile-hanging steel bar. The strip connecting plate in the connector passes through the tile seam and is placed on the roof tile, so that the vertical angle steel of the connector protrudes 200mm from the roof tile.

[0070] Instructions for installing roof tiles:

[0071] 1. Install the roof tiles from the eaves gutter toward the ridge. Lay the bottom row of roof tiles straight to ensure they are straight and extend 50-70mm into the eaves gutter to prevent rainwater from flowing back (urinating the eaves).
