Description

Technical Field

[0001] The utility model relates to the technical field of roof construction, in particular to a heat preservation node at a roof drainage ditch position. Background Art

[0002] In conventional roof projects (except green roofs), in order to ensure the depth of the drainage ditch, the existing construction method is to cancel the insulation structure at the drainage ditch position, or to thin the insulation structure at the drainage ditch position. The existing construction method will weaken the integrity of the roof insulation, causing the drainage ditch position to become a weak point of roof insulation.

[0003] If the bottom of the gutter is constructed according to the conventional large-surface insulation thickness, the large-surface area outside the gutter needs to be backfilled to ensure the depth of the gutter, but this will greatly increase the thickness of the entire roof surface, which is less economical and has lower construction efficiency. Therefore, it is necessary to provide an insulation node at the roof gutter position, which can solve the problem of poor insulation performance at the roof gutter position in the prior art. Summary of the invention

[0004] The utility model aims to provide a thermal insulation node at the position of a roof drain ditch, which can solve the problem of poor thermal insulation performance at the position of the roof drain ditch in the prior art.

[0005] The utility model is achieved in this way:

[0006] A thermal insulation node at a roof gutter position comprises a roof panel, a leveling layer, a slope layer, a large-surface thermal insulation layer, a protective layer, a finishing layer, a gutter structure and a board bottom thermal insulation layer; the leveling layer is constructed on the top surface of the roof panel, the slope layer is constructed on the top surface of the leveling layer and is located on both sides of the gutter structure, and the slope layer slopes in the direction of the gutter structure; the large-surface thermal insulation layer is constructed on the top surface of the slope layer, and the large-surface thermal insulation layer is disconnected at the construction area of ​​the gutter; the protective layer is constructed on the top surface of the large-surface thermal insulation layer and the top surface of the leveling layer located at the construction area of ​​the gutter, the protective layer forms a concave structure at the construction area of ​​the gutter, and the gutter structure is constructed within the concave structure; the finishing layer is constructed on the top surface of the protective layer, and the finishing layer is disconnected at the construction area of ​​the gutter; the board bottom thermal insulation layer is constructed on the bottom surface of the roof panel, the board bottom thermal insulation layer is located directly below the gutter structure, the width of the board bottom thermal insulation layer is greater than the width of the gutter construction area, so that both ends of the board bottom thermal insulation layer extend to below the large-surface thermal insulation layer on both sides of the gutter structure.

[0007] The width of the overlapping area between the end of the bottom insulation layer and the end of the large surface insulation layer projected on the horizontal plane is not less than 300 mm.

[0008] A waterproof structure is constructed below the drainage ditch structure. The waterproof structure is located between the protective layer and the leveling layer, and both ends of the waterproof structure extend to between the slope layer and the large-surface thermal insulation layer.

[0009] The waterproof structure includes a vapor barrier layer and a waterproof membrane. The vapor barrier layer is laid on the top surface of the leveling layer and extends to the top surface of the slope layer. Two layers of waterproof membranes are laid on the vapor barrier layer in sequence. The protective layer and the large-surface insulation layer are respectively constructed on the two layers of waterproof membranes.

[0010] A first isolation layer is constructed between the large-surface insulation layer and the protective layer. The horizontal section of the first isolation layer is constructed between the top surface of the large-surface insulation layer and the bottom surface of the protective layer. The vertical section of the first isolation layer extends between the disconnected surface of the large-surface insulation layer and the side surface of the protective layer.

[0011] The concave structure of the protective layer is sloped toward the rainwater outlet of the drainage ditch structure, and a bidirectional steel mesh is arranged in the protective layer.

[0012] The lower end of the vertical section of the first isolation layer extends to the connection node of the slope layer, the protective layer and the leveling layer.

[0013] A second isolation layer is constructed between the top surface of the protective layer and the bottom surface of the finishing layer, and the second isolation layer is disconnected at the construction area of ​​the drainage ditch.

[0014] A cover plate is arranged on the top of the drainage ditch structure.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. The utility model is provided with a large-surface insulation layer and a bottom insulation layer. The large-surface insulation layer forms a large-surface insulation effect on the roof structure, and the bottom insulation layer forms an insulation effect at the bottom of the gutter structure. When the large-surface insulation layer is disconnected in the gutter construction area, the gutter position can be prevented from becoming a weak point of roof insulation. The bottom insulation layer and the large-surface insulation layer form a staggered overlap effect in space, thereby ensuring the insulation performance and overall insulation effect of the entire roof structure, without increasing the thickness of the roof surface layer and almost without incurring additional costs.

[0017] 2. The utility model is provided with a first isolation layer and a protective layer. The first isolation layer can wrap and protect the large-surface insulation layer. The protective layer and the bidirectional steel mesh inside it can ensure the forming effect of the drainage ditch construction area. In addition, by setting the slope of the rainwater outlet of the drainage ditch structure, the efficient drainage effect of the drainage ditch structure is ensured. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Please see attached Figure 1 , an insulation node at the position of a roof gutter, comprising a roof panel 1, a leveling layer 2, a slope layer 3, a large-surface insulation layer 5, a protective layer 7, a finishing layer 8, a gutter structure 9 and a bottom insulation layer 10; the leveling layer 2 is constructed on the top surface of the roof panel 1, the slope layer 3 is constructed on the top surface of the leveling layer 2 and is located on both sides of the gutter structure 9, and the slope layer 3 is sloped toward the gutter structure 9; the large-surface insulation layer 5 is constructed on the top surface of the slope layer 3, and the large-surface insulation layer 5 is disconnected at the construction area of ​​the gutter; the protective layer 7 is constructed on the top surface of the large-surface insulation layer 5 and the leveling layer 2 is located on the top surface of the drainage ditch construction area, the protective layer 7 forms a concave structure in the drainage ditch construction area, and the drainage ditch structure 9 is constructed in the concave structure; the finishing layer 8 is constructed on the top surface of the protective layer 7, and the finishing layer 8 is disconnected in the drainage ditch construction area; the bottom insulation layer 10 is constructed on the bottom surface of the roof panel 1, and the bottom insulation layer 10 is located directly below the drainage ditch structure 9. The width of the bottom insulation layer 10 is greater than the width of the drainage ditch construction area, so that the two ends of the bottom insulation layer 10 extend to the bottom of the large surface insulation layer 5 on both sides of the drainage ditch structure 9.

[0022] After the roof panel 1 is constructed according to conventional technology, it is leveled by the leveling layer 2, and the slope is leveled on both sides of the drainage ditch structure 9 by the slope layer 3 to facilitate drainage of the roof. The roof is insulated by the large surface insulation layer 5, and the drainage ditch structure 9 is constructed by the concave structure formed by the protective layer 7, so that the depth of the drainage ditch structure 9 meets the design requirements, and finally the roof is decorated by the finishing layer 8.

[0023] The roof insulation layer 5 is disconnected at the gutter structure 9 to ensure the depth of the gutter structure 9 and avoid increasing the thickness of the roof structure. In order to ensure the insulation effect of the gutter structure 9, a bottom insulation layer 10 is constructed on the bottom surface of the roof panel 1, and the bottom insulation layer 10 covers the entire gutter construction area, ensuring the overall insulation effect of the roof and avoiding weakening the insulation performance at the gutter construction area.

[0024] The width of the overlapping area between the end of the bottom insulation layer 10 of the board and the end of the large surface insulation layer 5 projected on the horizontal plane is not less than 300 mm, that is, the overlap width between the bottom insulation layer 10 of the board and the large surface of the bottom of the large surface insulation layer 5 is not less than 300 mm, thereby ensuring the overall insulation performance of the entire roof structure and also ensuring the insulation performance in the drainage ditch construction area.

[0025] A waterproof structure 4 is constructed below the drainage ditch structure 9 . The waterproof structure 4 is located between the protective layer 7 and the leveling layer 2 , and both ends of the waterproof structure 4 extend between the slope layer 3 and the large-surface thermal insulation layer 5 .

[0026] Through the construction of the waterproof structure 4, the waterproof and anti-seepage performance of the roof structure is guaranteed, especially the waterproof and anti-seepage performance in the drainage ditch construction area.

[0027] The waterproof structure 4 includes a vapor barrier layer and a waterproof membrane. The vapor barrier layer is laid on the top surface of the leveling layer 2 and extends to the top surface of the slope layer 3. Two layers of waterproof membranes are laid on the vapor barrier layer in sequence. The protective layer 7 and the large-surface insulation layer 5 are respectively constructed on the two layers of waterproof membranes.

[0028] The vapor barrier can prevent indoor water vapor from penetrating into the large surface insulation layer 5 through the roof panel 1, thereby affecting the insulation effect of the large surface insulation layer 5 and preventing the waterproofing membrane from bulging. The two waterproof membranes can effectively ensure the anti-seepage and waterproof performance of the roof and the gutter structure 9.

[0029] A first isolation layer 6 is constructed between the large-surface insulation layer 5 and the protective layer 7. The horizontal section of the first isolation layer 6 is constructed between the top surface of the large-surface insulation layer 5 and the bottom surface of the protective layer 7. The vertical section of the first isolation layer 6 extends between the broken surface of the large-surface insulation layer 5 and the side surface of the protective layer 7.

[0030] By constructing the first isolation layer 6 having horizontal sections and vertical sections, the large-surface thermal insulation layer 5 can be wrapped and protected, thereby avoiding damage to the large-surface thermal insulation layer 5 when constructing the protective layer 7.

[0031] The concave structure of the protective layer 7 is sloped toward the rainwater outlet of the drainage ditch structure 9, and a bidirectional steel mesh (not shown in the figure) is arranged in the protective layer 7 to improve the structural strength of the protective layer 7.

[0032] The lower end of the vertical section of the first isolation layer 6 extends to the connection node of the slope layer 3, the protective layer 7 and the leveling layer 2.

[0033] When the waterproof structure 4 is laid, the waterproof structure 4 is passed around the lower end of the vertical section of the first isolation layer 6, and extended from the inner side of the lower end of the vertical section of the first isolation layer 6 to the slope layer 3, thereby ensuring the structural strength and waterproof performance of the connection nodes of the lower end of the vertical section of the first isolation layer 6, the slope layer 3, the protective layer 7 and the leveling layer 2.

[0034] A second isolation layer 11 is constructed between the top surface of the protection layer 7 and the bottom surface of the finishing layer 8, and the second isolation layer 11 is disconnected at the construction area of ​​the drainage ditch.

[0035] The second isolation layer 11 can play the role of isolation and protection, and at the same time can ensure that the surface of the finishing layer 8 is smooth and beautiful after construction.

[0036] A cover plate 12 is provided on the top of the drainage ditch structure 9 .
