Basement exterior wall single-face formwork supporting system and construction method thereof

Abstract

The invention discloses a basement exterior wall single-face formwork supporting system. The basement exterior wall single-face formwork supporting system comprises multiple split screws and steel pipe inclined struts. An embedded steel bar is welded to one end of each split screw, and the other ends of the embedded steel bars are connected with the inner side of an underground supporting pile. One ends of the steel pipe inclined struts are fixedly connected with the side of a basement exterior wall, and the other ends of the steel pipe inclined struts are connected with the top ends of steelbar ground anchors pre-buried on the inner sides of a basement bottom plate. Hanging net grout spraying is arranged on the outer side of the underground supporting pile, and a full rack is arranged atthe top of the basement bottom plate. In the basement exterior wall single-face formwork supporting system, during basement exterior wall single-face formwork construction, inclined steel pipes withgood rigidity are used for transmitting transmitted horizontal lateral pressure to the ground anchors, horizontal force is converted into pressure to the building ground and shear force to the groundanchors, embedded bars on the supporting piles and the split screws planed on the concrete side face of the exterior wall are used for connecting and butt welding, an exterior wall formwork is reinforced, operation is overall safe and firm, stability is good, and the phenomenon that formwork exploding and formwork expanding happen during concrete pouring is avoided.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a single-sided formwork support system for a basement exterior wall and a construction method thereof. Background technique [0002] With the construction and development of cities and the renovation of old houses, the available urban land space for construction is decreasing. In order to save land, most of the new buildings are built close to the planning red line, which makes the basement walls and foundations of high-rise buildings The distance between the enclosures of the pit is getting smaller and smaller, or even no spacing. The enclosure wall acts as the outer formwork of the basement outer wall, and only the inner formwork of the outer wall can be supported. [0003] Due to the different design functions and excavation depths of the basements of high-rise buildings, the heights of the basements of high-rise buildings are also different, and the thickness of the walls...

AI Technical Summary

Problems solved by technology

[0003] Due to the different design functions and excavation depths of the basements of high-rise buildings, the heights of the basements of high-rise buildings are also different, and the thickness of the walls is also different. The height and thickness of these walls are beyond the basement of conventional construction. The side pressure of the wall and formwork is relatively large. The conventional construction method only uses steel pipe frames for support, which is prone to mold explosion and expansion during concrete pouring. The traditional shaped triangular steel frame is used for support. The tripod is supported before the project starts. Initially, according to various factors such as the floor height and wall thickness of the basement, custom processing is often carried out, and the production cost is often high, and the turnover rate is not high, resulting in a waste of resources
