Construction method of compound single-side formwork system for basement exterior wall

Abstract

The invention relates to a construction method of a composite single-side formwork system for an outdoor wall of a basement, comprising the steps of: 1) construction preparation; 2) layout of a transverse support waist beam; 3) construction of a prefabricated tire formwork support; 4) formwork support at the bottom of an outdoor wall of a basement; 5) Concrete pouring construction of the basement exterior wall; 6) Sliding formwork construction of the basement exterior wall. The beneficial effects of the present invention are: the pile side hoop plate and the support pile are connected through the connecting anchor bolt and the hoop plate anchor bar, and the transverse brace waist beam is connected with the pile side hoop plate through the waist beam hoop, which reduces the difficulty of component connection. The integrity of the structure is improved; at the same time, the present invention arranges the first connecting hoop and the second connecting hoop at the longitudinal junction of the cross support waist beam, and the outer wall of the first connecting hoop and the second connecting hoop Auxiliary tie bars are set between the tie support plates, which can effectively improve the connection strength of the cross brace waist beam and reduce the difficulty of connection positioning.

Description

technical field [0001] The invention relates to a construction method of a composite single-side formwork system for an exterior wall of a basement, belongs to the field of construction engineering, and is suitable for the single-side formwork construction project of an exterior wall of a basement. Background technique [0002] Building basement engineering is an important measure to expand the space of building land. For some construction projects located in prosperous urban areas, due to the influence of buildings and structures in the surrounding area, only one-sided formwork construction can be used in the construction of basement exterior walls. However, this construction technology has certain difficulties in formwork processing and construction installation, and there are often problems such as weak formwork integrity, grout leakage, and difficult positioning. [0003] In the prior art, there is a single-sided formwork structure for the basement exterior wall structur...

AI Technical Summary

Problems solved by technology

The construction structure is simple and the construction efficiency is high. Although it can solve the engineering construction problem that there is no construction work surface outside the underground structure to a certain extent, construction techniques such as strengthening the stability of the construction structure and improving the quality control of concrete pouring still need further research. Moreover, the structure does not involve construction techniques such as formwork support and positioning.
