Description

Technical Field

[0001] The utility model relates to the technical field of precast walls, in particular to a precast wall for assisting the waterproof construction of the basement external wall. Background Technique

[0002] A precast wall panel is a reinforced concrete slab-type component processed in a precast factory (yard) or construction site for building assembly, abbreviated as a wall panel or a panel. Using precast concrete wall panels to build precast large-panel buildings can improve the degree of factory and mechanized construction, reduce on-site wet operations, save on-site labor, overcome seasonal influences, and shorten the building construction period.

[0003] For example, a precast wall for assisting the waterproof construction of the basement external wall disclosed in the authorized announcement number CN205742518U. The precast wall for assisting the waterproof construction of the basement external wall includes a structural beam slab, a strip board, a steel clip, and a plaster layer. One end of the steel clip clamps the strip board, and the other end is fixed in the structural beam slab. The strip board is perpendicular to the structural beam slab, and a plaster layer is provided between the two. Compared with the related technology, the precast wall for assisting the waterproof construction of the basement external wall provided by the utility model uses a bonding layer to seal at the splicing joint of the strip board and the structural beam slab, and the strip board is sealed with a sealing layer, with double sealing, having a good waterproof effect and improving the project image. The assembly structure is simple, the appearance is neat and beautiful after splicing, the strip board is light in weight and easy to assemble, saving a large amount of labor and accelerating the construction progress. However, this precast wall lacks more firm connection measures with the load-bearing wall and effective connection measures between precast walls, which is not convenient to ensure the overall bearing effect of this precast wall. Therefore, we propose a precast wall for assisting the waterproof construction of the basement external wall, which solves the structural connection problem of this precast wall, improves the integrity and use stability of the precast wall, and thus improves the building quality. Content of the Utility Model

The load-bearing wall is provided with a first reserved hole, the first reserved hole can insert a first embedded steel bar, one end of the first embedded steel bar is fixedly installed inside the precast wall, and DEA bonding mortar is filled between the precast wall and the load-bearing wall.

[0007] Preferably, the slow-expansion rubber waterstop is arranged at the water-facing end of the gap between the precast wall and the load-bearing wall.

[0008] Preferably, a waterproof layer is arranged on the water-facing side of the precast wall, and the waterproof layer is constructed by closely pasting asphalt waterproof coiled material.

[0009] Preferably, the crack-sealing tape is arranged outside the connecting seams between the load-bearing wall and the precast wall and between the precast walls.

[0010] Preferably, the vertical embedded steel bars are fixedly arranged inside the precast wall, and both ends thereof extend to the outside of the precast wall.

[0011] Preferably, the second reserved hole is arranged on one side of the precast wall, the second embedded steel bar is fixedly arranged inside the precast wall, and one end thereof can be inserted into the second reserved hole.

[0012] Preferably, the crack-sealing tape is made of alkali-resistant fiberglass mesh cloth, the width of the crack-sealing tape covers the structural joint, and both sides extend 100-150 mm beyond the edge of the structural joint.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. For the precast wall for assisting the waterproof construction of the basement exterior wall, through the arrangement of the first reserved hole and the first embedded steel bar, the precast wall and the load-bearing wall can be connected into a whole. Compared with the conventional spliced precast wall, this connection method has better overall compressive and seismic performance, improves the firmness of the building structure, reduces the settlement difference, prevents wall cracking or deformation, and improves the building quality. Through the arrangement of the second reserved hole and the second embedded steel bar, the integrity between the precast walls is strengthened, the weakness and looseness at the connection are avoided, and the overall stability is improved.

[0015] 2. For the precast wall for assisting the waterproof construction of the basement exterior wall, through the arrangement of the slow-expansion rubber waterstop, the waterproof layer and the crack-sealing tape, the connection gaps between the structures can be effectively sealed. The crack-sealing tape can block the water vapor from infiltrating into the connection seam and play the first waterproof role. The waterproof layer can prevent the water seepage and dampness on the water-facing side of the precast wall, and the slow-expansion rubber waterstop can expand when encountering water and play the second waterproof role for the connection seam. This double waterproof method effectively resists the external water vapor from entering the connection seam inside, avoids the corrosion and damage of the wall and the internal embedded steel bars, and improves the building durability.
