Method for manufacturing reinforced concrete basement external wall

Abstract

The invention discloses a method for manufacturing a reinforced concrete basement external wall. The method is characterized by installing a cork at the two ends of a pull screw with a water stop iron plate respectively when the pull screw is connected with an internal formwork and an external formwork, connecting reinforcing steel pipes to the two ends of the pull screw respectively at the external sides of the internal and external formworks, then pouring a reinforced concrete basement external wall in a conventional way, later, prying out the corks manually so that cork holes can be formed on the surface of the reinforced concrete basement external wall at the moment, cutting off the parts exposed out of the cork holes, of the pull screw, filling and leveling up the cork holes with waterproof mortar and then carrying out waterproof construction on the surface of the reinforced concrete basement external wall by the conventional method. The method has the advantages of construction convenience, high construction efficiency, good waterproof effect, low construction cost and good construction quality, and economic and social benefits can be brought to the enterprises by adopting the method.

Description

Technical field [0001] The invention relates to a method for manufacturing a basement reinforced concrete outer wall, and belongs to the technical field of manufacturing a basement reinforced concrete outer wall. Background technique [0002] At present, reinforced concrete technology has been widely used in construction engineering and municipal engineering. In recent years, cast-in-place reinforced concrete technology has developed more rapidly in high-rise buildings, and is particularly widespread. The existing high-rise buildings are mostly frame-shear and shear wall structures, and box or raft foundations are mostly used. Most of the projects are equipped with basements. At present, in the construction of cast-in-place concrete on the outdoor wall of the basement, in order to maintain the distance between the formwork on both sides and bear the lateral pressure of the concrete and other loads, the whole wall through-wall opposite pull screw with a water stop is generally use...

AI Technical Summary

Problems solved by technology

After the concrete pouring of the basement exterior wall is completed and the formwork is removed, gas cutting is required to cut off the exposed part of the pulling screw on both sides of the wall. After gas cutting, there will often be a section of the screw head protruding from the wall that will affect the construction of the next waterproofing process. It is also necessary to manually chisel out the concrete around the screw head, chisel out a small hole with a depth of 20mm, and then gas-cut off the screw head protruding from the outer wall surface, which increases the construction cost and prolongs the construction period. It is easy to loosen the water-stop pull screw during the process

Due to the high waterproof requirements of the basement wall, if the anti-wall screw is not properly treated, the anti-tie screw will easily form a water seepage channel after corrosion, causing leakage points on the outer wall, leaving hidden dangers for the future waterproofing of the outer wall

And when the earthwork is backfilled, it is very difficult to handle

Therefore, the manufacturing method of existing basement reinforced concrete exterior wall is not ideal enough yet
