Description
Technical Field
[0001] The utility model relates to the technical field of waterproof coiled materials, and specifically relates to a carcass overlapping structure. Background Art
[0002] The waterproof material product made by impregnating asphalt or polymer waterproof materials on the carcass is provided in the form of a roll, which is called a waterproof roll.
[0003] Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc. It is a flexible building material product that can be rolled into a roll to resist the seepage of external rainwater and groundwater. As a leak-free connection between the project foundation and the building, it is the first barrier to waterproofing the entire project and plays a vital role in the entire project.
[0004] At present, two coils are generally connected by overlapping. However, due to the high temperature in summer construction, the cohesive force of the coil is small after being exposed to high temperature, which can easily lead to warping or detachment at the overlap of the coil. Therefore, a carcass overlapping structure is provided. Utility Model Content
[0005] The utility model aims to provide a carcass overlap structure to solve the problem that the overlap of the coiled material may warp or come apart due to the low cohesive force of the coiled material after being subjected to high temperature during construction in summer.
[0006] To achieve the above purpose, the utility model provides the following technical solution: a carcass overlap structure, comprising:
[0007] The waterproof coiled material body comprises a carcass, an adhesive layer and a waterproof layer, wherein the adhesive layer is located between the carcass and the waterproof layer and is used to connect the carcass and the waterproof layer;
[0008] The upper overlap portion is located on one side of the waterproof coiled material body, and includes a mesh layer embedded between the carcass and the waterproof layer. The waterproof layer is wrapped around the end of the mesh layer to form a bent portion. The mesh layer and the bottom of the bent portion are jointly provided with an upper bonding portion.
[0009] The lower overlapping portion is located on the other side of the waterproof coiled material body and includes a lower bonding portion located on the carcass.
[0010] Preferably, the grid layer comprises a supporting portion and a contact portion;
[0011] One end of the support portion is embedded between the carcass and the waterproof layer to support the upper overlap portion;
[0012] The contact portion is located at the other end of the supporting portion and is used for contacting the bending portion.
[0013] Preferably, the contact end of the contact portion is configured as an arc-shaped surface.
[0014] Preferably, the widths of the upper overlapping portion and the lower overlapping portion are the same, and are not less than 80 mm.
[0015] Preferably, the width of the bent portion covering the bottom surface of the grid layer is 20 mm.
[0016] Compared with the prior art, the utility model has the following beneficial effects: the utility model provides a carcass overlap structure, in which a mesh layer is embedded between the carcass and the waterproof layer at the upper overlap portion, thereby supporting the upper overlap portion and increasing the stability of the upper overlap portion. When the construction temperature is high in summer, the problem of the roll material coming apart at the overlap due to the low cohesion after high temperature is avoided. A bending portion is formed by wrapping the waterproof layer around the end of the mesh layer and bonding the bending portion to the carcass, thereby avoiding the problem of warping at the overlap of the roll material. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.
[0020] See also Figure 1The utility model provides a technical solution: a carcass overlap structure, comprising: a waterproof roll body comprising a carcass 1, an adhesive layer 2 and a waterproof layer 3, the adhesive layer 2 is located between the carcass 1 and the waterproof layer 3, and is used to connect the carcass 1 and the waterproof layer 3; an upper overlap portion is located on one side of the waterproof roll body, comprising a mesh layer 4 embedded between the carcass 1 and the waterproof layer 3, the waterproof layer 3 is wrapped around the end of the mesh layer 4 to form a bending portion 5, and the mesh layer 4 and the bottom of the bending portion 5 are jointly provided with an upper adhesive portion 6; a lower overlap portion is located on the waterproof roll body The other side of the body includes a lower bonding portion 7 located on the carcass 1, and a mesh layer 4 is embedded between the carcass 1 and the waterproof layer 3 through the upper overlapping portion, so as to support the upper overlapping portion and increase the stability of the upper overlapping portion. When the construction temperature is high in summer, the problem of the coiled material being detached at the overlapping portion due to the low cohesive force after high temperature is avoided. The waterproof layer 3 is wrapped around the end of the mesh layer 4 to form a bending portion 5, and the bending portion 5 is bonded to the carcass 1 to avoid the problem of warping at the overlapping portion of the coiled material.
[0021] Specifically, the mesh layer 4 includes a support portion 4-1 and a contact portion 4-2; one end of the support portion 4-1 is embedded between the carcass 1 and the waterproof layer 3, and is used to support the upper overlap portion, thereby increasing the stability of the upper overlap portion and avoiding the low cohesion of the coil after being subjected to high temperature; the contact portion 4-2 is located at the other end of the support portion 4-1, and is used to contact the bending portion 5, thereby supporting the bending portion 5 and avoiding the low cohesion of the coil after being subjected to high temperature.
[0022] Specifically, the contact end of the contact portion 4 - 2 is configured as an arc surface. When two waterproof membrane bodies are overlapped, the arc surface of the contact portion 4 - 2 effectively prevents the end of the mesh layer 4 from damaging the waterproof layer 3 .
[0023] Specifically, the width of the upper overlapping portion and the lower overlapping portion are the same, and the width is not less than 80 mm. The overlapping portion is not less than 80 mm, thereby ensuring the stability of the connection between the upper overlapping portion and the lower overlapping portion.
[0024] Specifically, the width of the bent portion 5 covering the bottom surface of the mesh layer 4 is 20 mm, which effectively wraps the end of the mesh layer 4 and ensures the stability of the bent portion 5 connected to the carcass 1 through the upper bonding portion 6 and the lower bonding portion 7.
[0025] Working principle: When the utility model is in use, the upper overlapping part of one waterproof roll body is overlapped with the lower overlapping part of another waterproof roll body, and the upper bonding part 6 of the upper overlapping part is bonded and connected with the lower bonding part 7 of the lower overlapping part to achieve the overlap of the two waterproof rolls.
