Basement bottom plate rear pouring tape construction method

Abstract

A late poured band construction method of basement soleplate belongs to the technical field of building construction, and is characterized in that a plain concrete cushion is poured and extended below a late poured band, a reinforced cushion as well as corresponding drainage ditches and dilatation joints are poured and installed above the plain concrete cushion; after the reinforcing steel bars of basement soleplate are finished to be bundled, one side of the late poured band is supported and poured with concrete, and the other side of the same basement soleplate is poured with concrete; the late poured band is cleaned and is poured with concrete so as to finally be sealed. The late poured band construction method of basement soleplate greatly reduces the operation capacity of chiseling off loosened concrete at both sides of the late poured band, thereby favourably guaranteeing the reliable connection between the basement soleplate and the reinforcing bar cushion, avoiding gaps between the basement soleplate and the reinforcing bar cushion due to shrinkage, effectively preventing groundwater from entering before the late poured band is sealed, and keeping dryness inside the basement; otherwise, the reinforcing steel bars under the basement soleplate are avoided to be buried by cement paste or sundries, thereby reducing the labor cleaning strength, and greatly improving the construction quality of late poured band.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a construction method for post-pouring belts of basement bottom plates. Background technique [0002] Since the reform and opening up, especially in the past ten years, my country's social economy has developed rapidly, the construction scale has become increasingly grand, and the structural forms have become more complex and diverse, especially the ultra-long and ultra-deep basement structures and the connection of high-rise main buildings with low-rise or multi-storey podium buildings There are many structural forms. In order to ensure the integrity of the structure and the impermeability of the basement structure, the design usually adopts the form of post-cast strips as temporary deformation joints left in the cast-in-place overall reinforced concrete structure. After the main structure is completed within a certain period of time, after the settleme...

AI Technical Summary

Problems solved by technology

However, the current post-cast construction method of the basement floor cannot avoid the problem that the steel bars under the basement floor are buried by cement slurry or sundries. It is time-consuming and laborious to clean up, and the effect is not good, which affects the construction quality.
