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.

Abstract

The invention relates to a construction method of a basement exterior wall composite single-side formwork supporting system. The construction method comprises the steps including 1) construction preparation; 2) cross-brace wale arrangement; 3) prefabricated base form support construction; 4) basement exterior wall bottom form supporting; 5) basement exterior wall concrete pouring construction; and6) basement exterior wall sliding form supporting construction. The construction method provided by the invention has the beneficial effects that pile side hoop plates are connected with a support pile through a connecting anchor bolt and hoop plate anchor bars, a cross-brace wale is connected with the pile side hoop plates through a wale hoop, the component connecting difficulty is reduced, andthe structure integrity is improved; and meanwhile, a first connecting hoop and a second connecting hoop are arranged in longitudinal connecting positions of the cross-brace wale correspondingly, auxiliary tie bars are arranged between tie bar supporting plates on the outer side walls of the first connecting hoop and the second connecting hoop correspondingly, the connecting strength of the cross-brace wale can be effectively improved, and the connecting positioning difficulty can be effectively lowered.

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...
