Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a deformation joint of unequal-height floors of a basement. Background Art

[0002] Expansion joints are gaps between buildings, which require that the entire building be disconnected from the foundation to the main structure and then to the roof. By setting up effective expansion joints, it is possible to resist uneven settlement of the building or expansion and contraction caused by factors such as temperature and humidity.

[0003] Expansion joints also need to be set up in the basement, but in actual construction projects, basement leakage is often encountered. After research, it is found that basement leakage is mostly concentrated in the expansion joints, so waterproof construction is required when constructing the expansion joints.

[0004] When setting expansion joints in basements, it is common to encounter situations where the floor elevations on both sides of the expansion joints are different. In this case, the method of setting the expansion joints needs to be carefully considered. The traditional method of simply using waterproof materials to make a waterproof layer at the expansion joints is prone to a decrease in waterproof effect due to material deterioration. How to solve the leakage problem at the expansion joints of traditional basements and improve the waterproof effect and durability of the expansion joints is a technical problem that needs to be solved urgently. Summary of the invention

[0009] A waterproofing assembly is arranged between the high side section of the basement structure and the low side section of the basement structure. The waterproofing assembly includes a waterproofing membrane assembly, a shale protection brick, and a fine stone concrete protective layer. The waterproofing membrane assembly covers the outer side of the upper wall of the high side section, the outer side of the cantilever of the high side section, the second gap, the outer side of the upper wall of the low side section, and the upper part of the low side section floor. Shale protection bricks are arranged in the vertical direction of the waterproofing membrane assembly, and a fine stone concrete protective layer is laid in the horizontal direction of the waterproofing membrane assembly.

[0010] In particular, the deformation joint sealing component includes polyurethane sealant and polystyrene strips, multiple layers of polystyrene strips are stacked up and down and arranged in the second gap, and the polyurethane sealant is applied on the outside of the polystyrene strips to seal the second gap.

[0013] In particular, the rubber asphalt waterproof coating covers the outer side of the upper wall of the high side segment, the upper part of the high side segment cantilever, the outer side of the SBS asphalt waterproof membrane and the upper part of the low side segment floor.

[0014] Specifically, the SBS asphalt chemical root-penetration resistant waterproofing membrane covers the outer side of the rubber asphalt waterproofing membrane.

[0016] In particular, earth is backfilled on the upper part of the low-side segmented floor, the outer side of the low-side segmented upper wall, the outer side of the high-side segmented cantilever slab, and the outer side of the high-side segmented upper wall.
