In the welding stage of the waterproof coiled material, the number of welds is large and the labor requirements are high. At the same time, due to the high roof temperature in summer, the thermal expansion and contraction of the waterproof coiled material is obvious, and its joints are very prone to cracking. In addition, due to the aging of the material caused by high temperature, the joints are very prone to leakage. Therefore, it is necessary to provide a TPO asbestos mesh waterproof and thermal insulation integrated composite roof panel, which can solve the problems of many construction processes of metal roof panels and easy cracking and leakage at the joints of waterproof coiled materials in the prior art.

[0006] The throw-out length of the asbestos mesh reinforcement layer is greater than the throw-out length of the TPO waterproofing membrane, so that the asbestos mesh reinforcement layer can cover the joint between the TPO waterproofing membrane and the next integrated composite roofing panel.

[0007] The roof panel bottom plate is a corrugated steel plate, and the roof panel bottom plate is fixedly installed on the roof purlin.

[0008] An extension portion is formed at the end of the bottom plate of the roof panel located at the edge of the roof structure, and the extension portion extends upward to the top surface of the TPO asbestos mesh layer to form a locking edge structure.

[0009] The end of the roof panel bottom plate forms a tongue-and-groove structure, so that two adjacent integrated composite roof panels are spliced ​​through the tongue-and-groove structure on the roof panel bottom plate.

DETAILED DESCRIPTION

[0017] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Please see attached Figure 1 and attached Figure 2 A TPO asbestos mesh waterproof and heat-insulating integrated composite roof panel, comprising a TPO asbestos mesh layer 1, a heat-insulating layer 2 and a roof panel bottom plate 3; the TPO asbestos mesh layer 1 is compositely formed by a TPO waterproof coil 11 and an asbestos mesh reinforcement layer 12, the heat-insulating layer 2 is fixed on the top surface of the roof panel bottom plate 3, and the TPO asbestos mesh layer 1 is fixed on the top surface of the heat-insulating layer 2 to form an integrated composite roof panel; the TPO asbestos mesh layer 1, the heat-insulating layer 2 and one end of the roof panel bottom plate 3 are flush, and the TPO asbestos mesh layer 1 is The other end is thrown out of the other end of the insulation layer 2 and the roof panel bottom plate 3, so that when the two integrated composite roof panels are spliced, the TPO waterproof membrane 11 of the front integrated composite roof panel is overlapped and fixed on the TPO asbestos mesh layer 1 of the rear integrated composite roof panel through the connecting piece, and the asbestos mesh reinforcement layer 12 of the front integrated composite roof panel is overlapped for the second time on the TPO waterproof membrane 11 of the front integrated composite roof panel, the connecting piece and the asbestos mesh reinforcement layer 12 of the rear integrated composite roof panel.

[0019] During factory processing, the thermal insulation layer 2, the TPO waterproofing membrane 11 and the asbestos mesh reinforcement layer 12 are integrally formed from bottom to top through an integral molding technology, and then fixed to the roof panel bottom plate 3 to form an integral composite roof panel. During on-site construction, it is only necessary to splice and install the integral composite roof panel on the roof support structure. The integrated installation method greatly simplifies the construction process of the roof structure and is conducive to improving construction efficiency.

[0020] When splicing the integrated composite roof panels, the TPO waterproofing membrane 11 thrown out from the previous integrated composite roof panel is overlapped on the TPO asbestos mesh layer 1 of the next integrated composite roof panel, and then the asbestos mesh reinforcement layer 12 is overlapped for a second time on the TPO waterproofing membrane 11 and the TPO asbestos mesh layer 1 of the next integrated composite roof panel, thereby improving the connection reliability of the joint positions of adjacent integrated composite roof panels through multiple repeated overlaps, and preventing cracking, damage and leakage due to thermal expansion and contraction.

[0021] Please see attached Figure 1 The throw-out length of the asbestos mesh reinforcement layer 12 is greater than the throw-out length of the TPO waterproofing membrane 11, so that the asbestos mesh reinforcement layer 12 can cover the joint between the TPO waterproofing membrane 11 and the next integrated composite roofing panel.

[0022] The asbestos mesh reinforcement layer 12 thrown out of the previous integrated composite roof panel can cover the TPO waterproof membrane 11 thrown out of the integrated composite roof panel, and can cover the overlapping part between the TPO waterproof membrane 11 and the asbestos mesh reinforcement layer 12 of the next integrated composite roof panel. The two overlapping parts of the asbestos mesh reinforcement layer 12 and the TPO waterproof membrane 11 are staggered, thereby achieving a double waterproof and anti-seepage effect.

[0023] The secondary overlap protection of the TPO waterproof membrane 11 through the asbestos mesh reinforcement layer 12 can prevent the TPO waterproof membrane 11 from being lifted up due to wind pressure and causing fatigue damage at the joints, so that the splicing stability of the integrated composite roof panel is good, and leakage at the joints of the roof structure is further avoided.

[0024] Please see attached Figure 1 The roof panel bottom plate 3 is a corrugated steel plate, and the roof panel bottom plate 3 is fixed to the roof purlin 4 by a second self-drilling screw 8, which is easy to install and firmly connected.

[0025] Please see attached Figure 1 An extension portion 31 is formed at the end of the roof panel bottom plate 3 located at the edge of the roof structure, and the extension portion 31 extends upward to the top surface of the TPO asbestos mesh layer 1 to form a locking edge structure, thereby ensuring the structural strength and waterproof performance at the edge of the roof structure.

[0026] The TPO waterproofing coiled material 11, the asbestos mesh reinforcement layer 12 and the thermal insulation layer 2 are an integrally formed structure, which can be more convenient for on-site construction after being integrally formed and manufactured in the factory, thereby effectively simplifying the construction process.

[0027] The end of the roof panel bottom plate 3 forms a tongue-and-groove structure (not shown in the figure), so that two adjacent integrated composite roof panels are spliced ​​through the tongue-and-groove structure on the roof panel bottom plate 3 .

[0028] The tongue-and-groove structure makes the splicing of the roof panel bottom plate 3 more convenient and accurate. The structural form, quantity, spacing, etc. of the tongue-and-groove structure can be adaptively set according to actual splicing requirements to facilitate on-site assembly of the integrated composite roof panel.

[0029] A splicing gap is formed between the two adjacent integrated composite roof panels, and the splicing gap is filled with a foaming material (not shown in the figure), and the foaming material is covered by the TPO waterproof membrane 11 of the previous integrated composite roof panel in the splicing gap.

[0030] The foaming material can preferably be a foaming material such as polyurethane with good air tightness and thermal insulation properties to ensure that there are no cold bridges at the overlaps. At the same time, the flexible characteristics of the foaming material can ensure the waterproof and thermal insulation performance of the roof structure joints while avoiding deformation of the roof structure due to thermal expansion and contraction, forming a roof structure that integrates waterproofing and thermal insulation.

[0031] Please see attached Figure 1 and attached Figure 2 , the manufacturing method and construction method of the utility model are:

[0032] In a roofing project, the roof purlin 4 uses Q335BC200×70×20×2.0 cold-bent thin-walled C-shaped purlin; the roof panel bottom plate 3 uses a ≥0.75 thick white coated aluminum-zinc corrugated steel plate bearing plate, the aluminum-zinc coating is 60g / m2, and the surface coating is PE (front 25μm / back 10μm); the insulation layer 2 uses a 100mm thick rock wool board with a density of ≥180kg / m3 and a thermal conductivity of ≤0.040W / m, K; the TPO waterproofing membrane 11 uses a thermoplastic polyolefin (TPO) waterproofing membrane P type with a thickness of ≥1.5mm. The second self-drilling screw 8 uses an internal plum drill screw; the connecting piece uses a polypropylene PP membrane sleeve 6 and a first self-drilling screw 7.

[0033] The rock wool board, the asbestos mesh reinforcement layer 12 and the TPO waterproofing membrane 11 are compounded together by an integrated molding technology during factory processing. The asbestos mesh reinforcement layer 12 and the TPO waterproofing membrane 11 can be compounded by hot pressing bonding, and the TPO waterproofing membrane 11 and the rock wool board can be compounded by full bonding. After the roof panel bottom plate 3 is roll-formed, the composite TPO asbestos mesh layer 1 and the thermal insulation layer 2 are divided into strips and turned 90 degrees, and then hot-pressed and bonded on the roof panel bottom plate 3 through an adhesive through a production line to form an integrated composite roof panel.

[0034] During installation, the roof panel bottom plate 3 is fixed to the roof purlin 4 by the second self-drilling screws 8, and the adjacent two integrated composite roof panels are spliced ​​by the tongue-and-groove structure. The splicing gap between the adjacent two integrated composite roof panels is 20 mm, and the splicing gap is filled with polyurethane foam to ensure the air tightness and thermal insulation of the splicing parts of the integrated composite roof panels, and to ensure that there is no cold bridge at the overlap.

[0035] The TPO waterproofing coil 11 of the first integrated composite roof panel is fixed to the asbestos mesh reinforcement layer 12 of the second integrated composite roof panel through the polypropylene PP coil sleeve 6 and the first self-drilling screw 7, and hot air welding is performed. The asbestos mesh reinforcement layer 12 is then welded to the TPO waterproofing coil 11 of the first integrated composite roof panel and the asbestos mesh reinforcement layer 12 of the second integrated composite roof panel and covered with the polypropylene PP coil sleeve 6, forming multiple repeated overlaps at the joints of the two adjacent integrated composite roof panels, preventing the joints from cracking and leaking under the condition of thermal expansion and contraction, and ensuring the waterproof and heat-insulating effects of the entire roof structure while ensuring the waterproof and anti-seepage effects of the joints.

[0036] The integrated composite roof panels are spliced ​​in sequence and fixed to the roof purlin 4 by second self-drilling screws to form a closed, heat-resistant, aging-resistant and tear-resistant roof structure.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
