Description

Basement outer wall unilateral formwork structure

Technical Field

The utility model relates to the technical field of underground building construction, in particular to a unilateral formwork structure of an outer wall of a basement.

Background

At present, in the development of basement construction outer wall construction, because the distance between an outer wall structure and a support pile is smaller, double-sided formwork opposite-pull bolt construction of a foundation is difficult, and a single-sided formwork construction method can be adopted.

There are two types of single-sided formwork methods commonly used at present: the method comprises the following steps: a method of welding split bolts on the enclosure walls of the enclosure piles is adopted to carry out single-side formwork supporting. In the method, a diagonal brace is added on the back of a template to be used as a guarantee measure for preventing the die from expanding. The split bolts can damage the waterproof integrity of the basement outer wall, and later repair is time-consuming and labor-consuming. The second method is as follows: and adopting the section steel to manufacture a triangular truss to carry out single-side formwork supporting. In the method, because the profile steel truss is large in size, only the external wall concrete can be poured first, the beam slab bent frame and subsequent construction can be erected after the bracket is removed, the construction progress of the structure is affected, and the detached shaped profile steel truss is difficult to recycle for the second time.

The specific meaning of the above terms in the utility model will be understood by those skilled in the art according to the specific circumstances.

As shown in fig. 1 and 2, the present utility model provides a basement exterior wall single-side formwork structure, comprising: the support members 1 are vertically arranged, the support members 1 are arranged along the extending direction of the outer wall of the underground building, a connecting piece 2 is fixedly arranged between every two adjacent support members 1, a plurality of template fixing bolts 3 are fixedly welded on the connecting piece 2, and the plurality of template fixing bolts 3 are arranged from top to bottom and used for fixing templates. When the hydraulic grouting device is used, after the top plate of the basement is finished, H-shaped steel (the supporting piece 1) is pulled out by adopting a hydraulic device, and the gap of the steel is filled by grouting.

The unilateral formwork supporting structure of the basement outer wall can carry out unilateral formwork supporting in a narrow space of the outer wall and a construction method pile, solves the problem that a supporting body of formwork supporting drawknot is difficult to recover under the condition of general unilateral formwork supporting, and can recover and recycle the supporting body material H-shaped steel, save materials and reduce budget; the utility model has the characteristics of reasonable structure, safety and reliability and can be repeatedly used.

In a further improvement, the connecting piece 2 is clamped on the supporting piece 1. So that the support 1 can be smoothly withdrawn when being withdrawn.
