Description

Technical Field

[0001] This utility model relates to the field of waterproofing technology for post-pouring strips, specifically a waterproofing structure for post-pouring strips in basements. Background Technology

[0002] Basements are a widely used underground building structure, typically used to provide construction space for functional areas such as parking lots or underground shopping malls. The structure and foundation of high-rise buildings and podiums are designed as a whole, but during construction, a post-construction joint is used to temporarily separate the two parts. After the main structure is completed and most of the settlement has been accounted for, the concrete connecting the two parts is poured, linking the high and low floors into a unified structure. The foundation design should consider the different stress states of the two stages and perform strength checks separately. Backfilling is required within the construction joint; this backfilled area is also known as the post-construction joint area. Currently, traditional basement post-construction joints are generally waterproofed using waterproof membranes and coatings. Since the waterproof membrane is usually poured into the concrete, long-term use can lead to gaps between the membrane and the concrete, thus reducing the waterproofing performance of the post-construction joint. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a waterproof structure for post-cast strips in basements, which solves the problem that existing waterproof structures for post-cast strips are prone to corrosion and cracks when poured into concrete, thus improving the waterproof effect of post-cast strips in basements.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a waterproof structure for a basement post-cast strip, comprising a lower concrete layer, the upper surface of which is coated with a waterproof coating, the lower surface of which is provided with a waterproof layer, an external waterstop fixedly installed in the middle of the upper surface of the lower concrete layer, a waterstop caulking plate on the upper surface of the external waterstop, concrete retaining strips on both sides of the upper end of the waterstop caulking plate, fish scale mesh installed on the outer side of the concrete retaining strips, a waterstop steel plate fixedly installed at the upper end, and a rubber plate fixedly connected to the upper surface of the waterstop steel plate.

[0005] Preferably, the interior of the water-stop steel plate has a groove, and a PVC water-stop plate is installed inside the groove.

[0006] Preferably, both sides of the water-stop caulking plate are equipped with reinforcing ribs, one end of which is inserted into the interior of the lower concrete layer, and an intermediate concrete layer is poured on both sides of the water-stop caulking plate.

[0007] Preferably, an upper concrete layer is poured on both sides of the upper surface of the middle concrete layer, and the upper concrete layer is embedded with transverse reinforcing ribs and longitudinal reinforcing ribs, which are arranged perpendicular to each other.

[0008] Preferably, the waterproof layer includes a waterproof membrane and a waterproof roll, with the waterproof roll located below the waterproof membrane.

[0009] Preferably, a base layer is provided below the waterproof layer, and a through hole is provided inside the base layer. A drain pipe is fixedly connected to the lower surface of the base layer, and one end of the drain pipe extends and connects to the sewer pipe.

[0010] This utility model provides a waterproof structure for post-cast strips in basements. Compared with the prior art, it has the following advantages:

[0011] 1. By combining the waterproof mortar layer applied to the upper surface of the lower concrete layer and the external waterstop installed on the upper surface of the lower concrete layer with the intermediate concrete layer poured inside the lower concrete layer and the upper concrete layer poured on the upper surface of the intermediate concrete layer, as well as the waterstop steel plate and rubber plate inside the upper concrete layer, the problem of corrosion and cracks easily occurring in the existing post-cast strip waterproof structure is solved, thus improving the waterproof effect of the post-cast strip in the basement.

A water-stop caulking plate 11 is installed in the middle of the reinforcing rib layer 9, and an external water-stop strip 10 is laid below the water-stop caulking plate 11 to further prevent moisture from seeping into the gaps. Meanwhile, in the lower concrete layer... The upper surface of the lower concrete layer 3 is coated with waterproof mortar. Then, a middle concrete layer 8 is poured on the upper surface of the lower concrete layer 3. Then, symmetrical concrete retaining strips 15 are poured on the upper surface of the middle concrete layer 8.
