Construction method of single-side formwork support for basement exterior wall based on steel pipe truss

Abstract

The invention discloses a unilateral formwork supporting construction method for a basement exterior wall on the basis of a steel pipe truss. The method includes the steps of 1, carrying out embedment construction of a truss fixing structure and a formwork bottom fixing structure, specifically embedding the truss fixing structure for fixing the steel pipe truss into a supporting foundation and embedding the formwork bottom fixing structure for fixing a formwork into a guide wall; 2, erecting the steel pipe truss on the supporting foundation; 3, binding reinforcement cages of a wall body; 4, hoisting the formwork; 5, fixedly connecting the formwork to the steel pipe truss; 6, fixedly connecting the bottom of the formwork to the guide wall and specifically fixing the bottom of the formwork to the guide wall in a fastened mode through the formwork bottom fixing structure; 7 reinforcing the steel pipe truss; and 8, carrying out concrete pouring. The method has the advantages that the steps are simple, the design is reasonable, the construction is simple and convenient, and the use effect is good; and the steel pipe truss serves as a supporting structure, the truss fixing structure and the formwork bottom fixing structure realize the dual reinforcement effect, and therefore the unilateral formwork supporting effect of the basement exterior wall can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of basement exterior wall construction, and in particular relates to a single-side formwork construction method for basement exterior walls based on steel pipe trusses. Background technique [0002] With the increasing shortage of land for urban construction and the increase of land costs, it often occurs that the basement exterior wall is close to the foundation pit support structure, and the construction operation surface is no longer reserved. Therefore, when constructing the reinforced concrete exterior wall of the basement, only one-side formwork and support system construction can be carried out on the inner side of the exterior wall. During the single-side formwork construction of the basement exterior wall, the wall formwork model is changed from a traditional multi-span continuous beam slab to a cantilever formwork structure. The lateral pressure needs to be transmitted to the lower structure throug...

Problems solved by technology

But nowadays, there is no uniform, standard and standardized construction method to follow when constructing unilateral formwork on the exterior wall of the basement. Deformation, difficulty in guaranteeing construction quality of basement exterior walls, etc.
