Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of prefabricated building materials, and in particular to a prefabricated roof waterproof and thermal insulation integrated panel. Background Technology
[0002] Waterproofing and thermal insulation are common construction techniques for building roofs. In traditional processes, the entire roof base surface is first laid and sprayed with one or two waterproof layers, then the thermal insulation layer is laid, and finally the surface layer is laid after the thermal insulation layer has completely solidified.
[0003] With the development of construction technology, prefabricated roof waterproofing and thermal insulation integrated panels are gradually replacing traditional manual on-site construction. Based on the actual building roof structure, the factory mass-produces the integrated insulation panels according to the design dimensions. On-site installation is only required to follow the roof waterproofing layer laying and spraying, and then the integrated panels are installed on-site, which is convenient.
[0004] Patent CN214461845U discloses a prefabricated roof waterproof and thermal insulation integrated panel, which includes a panel body and connectors fixedly connected to the panel body. The panel body includes a waterproof layer, a thermal insulation layer, and a protective layer, which are fixedly connected sequentially from bottom to top. The panel body is provided with a fixing groove, and the inner wall of the fixing groove is provided with a sealing gasket that matches the shape and size of the inner wall of the fixing groove. The connectors are adapted to the shape and size of the fixing grooves and are fixedly connected to the fixing grooves by weather-resistant adhesive. The connectors and the fixing grooves are respectively fixedly connected to both sides of the panel body. When the panel body is assembled on the roof, the gaps between the panels are sealed with weather-resistant adhesive.
[0005] Therefore, it is evident that it provides a design that enables the integrated panels to interlock, thereby achieving a seal and stability between the integrated panels.
[0006] However, after the installation of this type of integrated waterproof and thermal insulation panel, although it improves the sealing between adjacent panels, the overall drainage on the roof is poor. Rainwater tends to accumulate on the roof and is not easily discharged from the drainpipes on the outside of the roof. Utility Model Content
[0007] In order to overcome the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a prefabricated roof waterproof and heat insulation integrated panel, which has drainage channels between adjacent integrated panels, and can effectively drain rainwater from the integrated panel to the gutter, with good drainage performance.
[0008] To achieve the above objectives, this utility model provides a prefabricated roof waterproof and thermal insulation integrated panel, including a first waterproof layer disposed on the base surface of the building top and a second waterproof layer disposed on the first waterproof layer, wherein multiple integrated panels are installed on the second waterproof layer in a matrix arrangement; the integrated panel is composed of an insulation layer and a surface layer interlocked together, and a relay drainage mechanism is provided between the integrated panels; a gutter is provided on the outer edge of the base surface of the building top, and the relay drainage mechanism is connected to the inner edge of the gutter, through which rainwater is discharged into the gutter.
[0009] Furthermore, the relay drainage mechanism includes side strips disposed between adjacent integrated plates in the left-right direction and intermediate strips disposed between adjacent integrated plates in the front-back direction. The intermediate strips have first flow ports on both sides corresponding to the port positions of the side strips, and the first flow ports are fitted with the ports of the side strips.
[0010] Furthermore, the relay drainage mechanism also includes side strips surrounding all integrated panels, the side strips abutting against the sides of the integrated panels; one side of the side strip is provided with a second flow port that communicates with the port of the side strip and the port of the middle strip at even intervals, and the other side of the side strip is provided with a third flow port that communicates with the pre-set drain outlet of the gutter.
[0011] Furthermore, the cross-sections of the side strips, the middle strips, and the side strips are U-shaped.
[0012] Furthermore, the inner walls of the side strips, middle strips, and side strips are uniformly coated with a waterproof coating.
[0013] Preferably, the insulation layer is pre-embedded with connecting embedded parts at uniform intervals, and the top of the connecting embedded parts is embedded in the surface layer; the connecting embedded parts are welded from U-shaped steel bars and square plates, wherein the U-shaped steel bars at the top of the connecting embedded parts are embedded in the surface layer.
[0014] Furthermore, the gap between adjacent integrated panels is 1-2 cm.
[0015] Preferably, the first waterproof layer is a waterproof mortar layer, and the second waterproof layer is a combination of an asphalt felt waterproof layer and an asphalt layer.
[0016] Furthermore, the thickness of the insulation layer is 7-8 cm, and the thickness of the surface layer is 5-10 cm.

[0019] 2. A relay drainage mechanism is installed on the waterproof layer, which can effectively prevent rainwater from directly contacting the waterproof layer and protect the waterproof layer while draining water. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] See below. Figures 1-4 This utility model provides a detailed description of the prefabricated roof waterproof and thermal insulation integrated panel.
[0028] like Figure 1-4As shown, the prefabricated roof waterproof and thermal insulation integrated panel of this utility model includes a first waterproof layer 1 set on the base surface of the building top and a second waterproof layer 2 laid on the first waterproof layer 1. Multiple integrated panels are installed on the second waterproof layer 2 in a matrix arrangement.
[0029] The integrated panel consists of an insulation layer 3 and a surface layer 5 that are interlocked. The gap between adjacent integrated panels is 2 cm, and a relay drainage mechanism is installed between the integrated panels. A gutter 9 is installed on the outer edge of the building's top base surface, and the relay drainage mechanism is connected to the inner edge of the gutter 9. Rainwater is discharged into the gutter 9 through the relay drainage mechanism.
[0030] The total thickness of the overlap between the first waterproof layer 1 and the second waterproof layer 2 is 10 cm. The first waterproof layer 1 is a waterproof mortar layer with a thickness of 8 cm. The second waterproof layer 2 is a combination of an asphalt felt waterproof layer and an asphalt layer. First, the asphalt layer is evenly coated on the first waterproof layer 1. Then, the asphalt felt waterproof layer is laid on the asphalt layer. Then, it is heated by a high-temperature torch and the asphalt layer is coated again.
[0031] The insulation layer 3 has a thickness of 7-8 cm, and the surface layer 5 has a thickness of 5-10 cm. In one specific embodiment, the insulation layer 3 has a thickness of 8 cm and is formed by the solidification of insulation mortar, while the surface layer 5 has a thickness of 10 cm and is a concrete layer.
[0032] like Figure 1 As shown, the insulation layer 3 is pre-embedded with connecting parts 4 at even intervals. The connecting parts 4 are welded together from U-shaped steel bars and square plates. The U-shaped steel bars at the top of the connecting parts 4 are embedded in the surface layer 5. This arrangement not only increases the embedding strength of the insulation layer 3 and the surface layer 5, but also increases the stability strength of the insulation layer 4 and the surface layer 5.
[0033] The relay drainage mechanism of this utility model includes side strips 6 arranged between adjacent integrated plates in the left-right direction and intermediate strips 7 arranged between adjacent integrated plates in the front-back direction. The intermediate strips 7 have first flow ports 71 on both sides corresponding to the port positions of the side strips 6, and the first flow ports 71 are fitted with the ports of the side strips 6.
[0034] The intermediate drainage mechanism also includes side drain strips 8 surrounding all the integrated panels. The side drain strips 8 abut against the sides of the integrated panels. One side of the side drain strips 8 is provided with second flow ports 81 that communicate with the ports of the side drain strips 6 and the middle drain strips 7 at even intervals. The side drain strips 8 arranged in the left-right direction are fitted with the ports of the side drain strips 6, and the side drain strips 8 arranged in the front-back direction are fitted with the ports of the middle drain strips 7.
[0035] In addition, a third flow port 82 is provided on the other side of the drain strip 8, which is connected to the pre-set drain port of the gutter 9.
[0036] The side strips 6, the middle strips 7, and the side strips 8 have U-shaped cross sections, and the inner walls of the side strips 6, the middle strips 7, and the side strips 8 are uniformly coated with a waterproof coating.
[0037] In addition, the side strips 6, the middle strips 7 and the side strips 8 are made of PVC. The three are the same height as the integrated panel and are flush with the side of the gutter 9 when laid on the base surface of the building top. This allows rainwater from the side strips 6, the middle strips 7 and the side strips 8 on the outer periphery of all integrated panels between adjacent panels to drain into the gutter 9, achieving the effect of drainage.
[0038] This utility model, by installing an integrated panel with a relay drainage mechanism on the building roof in a gap-like manner on a double-layer waterproof layer, creates drainage channels between adjacent integrated panels, thereby effectively draining rainwater from the integrated panels into the gutter 9 during rain, resulting in good drainage performance.
[0039] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any transformations or substitutions that can be understood by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of this utility model.
