Embodiment 1

[0028] like figure 1 As shown, an overlapping structure and construction method of a waterproof coiled material according to a preferred embodiment of the present invention, the overlapping structure of the waterproof coiled material includes two waterproof coiled materials whose ends are overlapped with each other, and one end of the waterproof coiled material It is an asymmetric concave structure 1, and the overlapping end of the other waterproof membrane is a corresponding convex structure 2. The overlapping parts of the two waterproof membranes are connected by an adhesive layer 3, and the surface of the waterproof membrane is The seams are also provided with a waterproof reinforcement coating 4 . Wherein, the waterproof coiled material is a SBS modified asphalt self-adhesive waterproof layer, which has a good waterproof effect, and the concave-shaped structure 1 at the end is side-standing, that is, the shape of the notch facing the side, and the concave-shaped structure ...

Embodiment 2

[0036] like figure 2 As shown, the overlapping structure of a waterproof coiled material in a preferred embodiment of the present invention includes two waterproof coiled materials whose ends are overlapped with each other, wherein the end of one waterproof coiled material has an asymmetric concave structure 1, and the other waterproof The overlapped ends of the coiled materials have corresponding convex structures 2, and the overlapping parts of the two waterproof coiled materials are connected by an adhesive layer 3, and a waterproof reinforcing coating 4 is provided at the seam of the surface of the waterproof coiled materials. Wherein, the waterproof roll material is a SBS modified asphalt self-adhesive waterproof layer, which has good waterproof effect. When the material is used in an environment with a steep slope or when the waterproof membrane is thick, the lap joint in the shape of a vertical notch can effectively increase the bonding force of the lap joint and avoid...

Embodiment 3

[0044] The overlapping structure of the waterproof membrane is the same as that in Example 1, except that the step (3) in the construction method is different, as follows:

[0045](3) Closely combine the two overlapping ends, press for 2 minutes, and then coat a layer of graphene-modified polyurethane on the seam of the upper surface of the waterproof membrane, the coating thickness is 0.3mm, and the width is 10cm. Just dry.

Abstract

The invention discloses an overlapping structure and a construction method of a waterproof coiled material, and belongs to the technical field of waterproof layer construction. The overlapping structure includes two waterproof rolls whose ends are overlapped with each other, wherein one end of the waterproof roll is in an asymmetric concave shape, and the end of the other waterproof roll is in a corresponding convex shape. The overlapping parts of the waterproof membrane are connected by an adhesive layer, and a waterproof strengthening coating is also provided at the seam of the surface of the waterproof membrane. The construction method of the lap joint structure is as follows: clean up the lap joint ends of the two waterproof rolls and remove the protective film; evenly coat the contact surfaces of the two lap joint ends with adhesive epoxy resin / graphene nanocomposite material ;Tightly combine the two overlapping ends, press for 2~5 minutes, and then apply a strong waterproof coating on the seam of the upper surface of the waterproof membrane, and let it dry. The overlapping structure can greatly improve the firmness of the overlapping structure of the waterproof coiled material, avoid water seepage and leakage, and has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of waterproof layer construction, in particular to an overlapping structure and a construction method of waterproof coiled materials. Background technique [0002] Waterproof membrane is a kind of building material commonly used in building construction. In the construction of road bridges, roofs or buildings that need waterproofing, waterproof membranes need to be laid in advance. The building waterproofing project is an important part of the construction project. The leakage of buildings is a more prominent quality problem in waterproofing projects, and this is closely related to the quality of the waterproof membrane. The processing is particularly important. [0003] In the construction of building waterproof layers, we often encounter the problem of overlapping construction of different waterproof membranes. For example, different monomers are designed by their respective construction or design units b...
