Description

Technical Field

[0001] The utility model relates to the field of roof thermal insulation and waterproofing, and more specifically, to a roof thermal insulation and waterproofing composite system. Background Art

[0002] At present, the thermal insulation and waterproofing system of roofs on the market is mainly a method of mechanically fixing TPO waterproofing membranes on rock wool boards on site. This roof system has poor thermal insulation and waterproofing performance. Rainwater easily enters the thermal insulation layer of the rock wool board through the gaps of the TPO waterproofing membrane, causing the rock wool board to lose its thermal insulation function and increase the load on the roof. In addition, the leaking point of the waterproofing membrane is not easy to find. The rock wool board and TPO waterproofing membrane are constructed in two times, which increases the construction cost. Utility Model Content

[0006] A composite board 100, wherein the composite board 100 is composed of an insulation board 110 and a waterproof membrane 120 stacked together; an upper tongue 112 and a lower tongue 113 are respectively provided on opposite sides of a body 111 of the insulation board 110; the waterproof membrane 120 and the insulation board 110 are bonded and connected by an adhesive layer 130, one side of the waterproof membrane 120 is flush with the edge of the upper tongue 112 of the insulation board 110, and the other opposite side of the waterproof membrane 120 extends outward beyond the edge of the body 111 of the insulation board 110;

[0007] The installation component 200 includes screws 210 and gaskets 220; when the two composite panels 100 are spliced, the screws 210 pass through the gaskets 220, the upper tongue and groove 112 of one insulation board 110 and the lower tongue and groove 113 of the other insulation board 110 to connect the two composite panels 100 to the roof; the outer surface of the gasket 220 is coated with a coating of the same material as the waterproof membrane 120.

[0008] Furthermore, the insulation board 110 is made of rock wool board.

[0009] Furthermore, the waterproof membrane 120 is a TPO waterproof membrane.

[0010] Furthermore, a groove 221 for accommodating the screw cap of the screw 210 is formed on the top surface of the gasket 220 .

[0011] Furthermore, the gasket 220 is constructed as a step structure, and the radial dimension of the upper layer is smaller than the radial dimension of the lower layer.

[0012] Furthermore, a portion of the gasket 220 is overlapped at a joint between the upper groove 112 of one insulation board 110 and the body 111 of another insulation board 110 .

When two composite panels are spliced ​​together, the two insulation panels are connected through a tongue-and-groove structure, and screws are used to pass through a gasket and the tongue-and-groove structure to connect the composite panel to the roof. The portion of the waterproof membrane of the composite panel on one side extending outwards covers the connecting gap and the gasket of the tongue-and-groove structure. Since the outer surface of the gasket is coated with a coating of the same material as the waterproof membrane, the portion of the waterproof membrane extending outwards is welded and connected to the gasket by electromagnetic induction welding, and then the portion of the waterproof membrane extending outwards is welded and connected to the overlapping portion of the top surface of the waterproof membrane of the composite panel on the other side by hot air welding, so as to avoid water leakage in the gap at the splicing.

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the utility model is described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, but not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figures 1 to 5 This embodiment provides a roof thermal insulation and waterproof composite system, including: a composite panel 100 and an installation assembly 200.

[0027] The composite board 100 is composed of a thermal insulation board 110 made of rock wool board and a waterproof coiled material 120 made of TPO material, forming a composite board with thermal insulation and waterproof functions. The waterproof coiled material 120 and the thermal insulation board 110 are bonded and connected by an adhesive layer 130 .

[0028] The two opposite sides of the body 111 of the insulation board 110 are respectively provided with an upper tongue and groove 112 and a lower tongue and groove 113 that match each other.

[0029] One side of the waterproof membrane 120 is flush with the edge of the upper groove 112 of the insulation board 110 , and the other side of the waterproof membrane 120 extends outward beyond the edge of the body 111 of the insulation board 110 , and the excess portion forms a covering portion 121 .

[0030] The installation assembly 200 includes a screw 210 and a gasket 220 ; the screw 210 has a nail head, the gasket 220 is made of galvanized aluminum steel plate, and the outer surface of the gasket 220 is coated with a TPO coating that is the same material as the waterproof membrane 120 .

[0031] When the two composite panels 100 are spliced, the upper tongue and groove 112 of one insulation board 110 and the lower tongue and groove 113 of the other insulation board 110 cooperate to form a tongue and groove structure, and the screws 210 pass through the gasket 220, the upper tongue and groove 112 of one insulation board 110 and the lower tongue and groove 113 of the other insulation board 110 to fix the two composite panels 100 to the purlin 300 of the roof. After the connection, the covering part 121 extending outward from the waterproof membrane 120 on one side covers the joint of the tongue and groove structure and the gasket 220, and then the covering part 121 is welded to the gasket 220 and the overlapping part of the waterproof membrane 120 on the other side by electromagnetic induction welding and hot air welding respectively, so as to reduce various splicing gaps.

[0032] Since the outer surface of the gasket 220 is coated with a TPO coating of the same material as the waterproof membrane 120, electromagnetic induction welding is used, based on the principle that electromagnetic induction can generate heat in a conductor, and the heat is used to weld the waterproof membrane 120 made of TPO material and the gasket 220 with a coating of the same material and then fuse them together. After welding, the heat of the gasket 220 is dissipated through a cooler, and the strong magnetism of the cooler is used to strengthen the adhesion between the gasket 220 and the covering portion 121 of the waterproof membrane 120, and the covering portion 121 of the waterproof membrane 120 extending outward is welded to the gasket 220.

[0033] In this embodiment, the gasket 220 is constructed as a step structure, and the radial dimension of its upper layer is smaller than the radial dimension of its lower layer. When the covering portion 121 of the waterproof membrane 120 on one side covers the gasket 220, the covering portion 121 extending outward from the waterproof membrane 120 can be more closely fitted with the overlapping edge of the gasket 220.

[0034] A groove 221 for accommodating the nut of the screw 210 is formed on the top surface of the upper layer of the gasket 220. After the screw 210 passes through the gasket 220, the nut of the screw 210 can be hidden in the groove 221 to avoid protrusion.

The insulation layer and the waterproof membrane are constructed at the same time, which saves construction time and construction procedures, realizes the functions of insulation and waterproofing, and reduces construction costs.

[0037] When two composite panels 100 are spliced, the upper tongue 112 of the insulation board 110 on one side and the lower tongue 113 of the insulation board 110 on the other side are spliced ​​to form a tongue structure, and the interface of the tongue structure is overlapped on the purlin 300 of the roof, and the screws 210 are used to pass through the gasket 220, the upper tongue 112 of the insulation board 110 on one side, and the lower tongue 113 of the insulation board 110 on the other side are fixedly connected to the purlin 300, and the gasket 220 is partially overlapped. At the joint between the upper groove 112 of one insulation board 110 and the main body 111 of the other insulation board 110; then the covering portion 121 extending outward from the waterproof membrane 120 on one side covers the upper groove 112 of the insulation board 110 on the other side and the gasket 220; finally, the covering portion 121 is welded to the gasket 220 and the overlapping portion of the waterproof membrane 120 on the other side by electromagnetic induction welding and hot air welding respectively.
