Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane technology, specifically a grid-type polymer waterproof membrane with zoned waterproofing function. Background Technology

[0002] Traditional pre-laid polymer waterproof membranes consist of a polymer sheet coated with a polymer adhesive layer, and a layer of fine sand sprinkled on top of the adhesive layer, creating a slightly textured structure. The membrane adheres to the subsequently poured concrete through the adhesive layer and the fine sand.

[0003] However, during the on-site construction of traditional pre-laid polymer waterproof membranes, the adhesive layer on the surface of the membrane is particularly susceptible to environmental factors (such as ultraviolet radiation, rainwater immersion, and construction in low-temperature weather), which reduces the adhesiveness of the adhesive layer. This leads to water seepage channels between the membrane and the subsequently poured concrete structure. Because the surface of the membrane is flat, once leakage occurs between it and the subsequent pouring, it is an unobstructed, non-directional leakage, and the leakage point cannot be located. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a grid-type polymer waterproof membrane with zoned waterproofing function, which can solve the existing problems.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A grid-type polymer waterproof membrane with zoned waterproofing function, comprising a substrate;

[0007] The grid unit is tightly connected to the substrate to form several independent waterproof zones on top of the substrate; during the waterproof membrane laying stage, the waterproof zones are used to increase the contact surface between the waterproof membrane and the grout; during the waterproof membrane application stage, the waterproof zones are used to lock infiltrated liquids within the area they enclose.

[0008] The overlapping part is located on the side surface of the base, and no grid units are provided at the overlapping part.

[0009] Furthermore, the overlaps between adjacent waterproof membranes are fixed by welding.

[0010] Furthermore, the surface of the overlapping portion is coated with an adhesive layer, and a film is adhered to the surface of the adhesive layer.

[0011] Furthermore, the grid unit is thermally fused and fixed to the substrate as a single unit.

[0012] Furthermore, the grid unit includes a first rib and a second rib, which are arranged in a grid pattern.

[0013] Furthermore, the first and second reinforcing bars are arranged in a plane and intersecting each other; the thickness of the first reinforcing bar is the same as the thickness of the second reinforcing bar or the thickness of the first reinforcing bar is greater than the thickness of the second reinforcing bar.

[0014] Furthermore, the first rib is fixed to the surface of the base, and the second rib is cross-fixed to the top of the first rib; the thickness of the first rib is the same as the thickness of the second rib or the thickness of the first rib is greater than the thickness of the second rib.

[0015] Furthermore, the first rib is arranged parallel to the length of the base, the second rib is arranged parallel to the width of the base, and the first rib and the second rib intersect perpendicularly.

[0016] Furthermore, both the first and second reinforcing bars are arranged at an angle.

[0018] Compared with the prior art, the beneficial effects of this utility model include:

[0019] 1. A waterproof partition can be formed on the top of the base through grid units. The waterproof partition confines the leakage liquid to an independent area to avoid spread. Compared with traditional pre-laid rolls, the leakage point is controllable. Once leakage occurs, it can be repaired at a fixed point without affecting adjacent partitions or the overall waterproof safety. There is no possibility of large-scale water seepage.

[0020] 2. When laying waterproof membrane, the grid unit can increase the connection surface between the base and the concrete. The grid unit and the concrete are physically interlocked and bonded, which is not affected by the environmental factors of the construction site. On-site pouring is simple and the bonding strength is high. Attached Figure Description
