Problems solved by technology

[0002] Our country generally adopts the method of double-side support formwork of the pull screw rod for the construction of building walls. In the construction of basement walls, due to the development of the enclosure structure, the distance between the basement exterior wall and the support structure is very limited. In some cases, the distance is usually 5cm-20cm, which makes it impossible to support the formwork outside the basement exterior wall. In addition, the complexity of the underground environment brings great difficulties to the formwork support of the basement exterior wall.
[0003] At present, the common method of supporting formwork in engineering is to plant reinforcement on the support pile, and then anchor it on the back of the formwork after lengthening it. The inner side of the outer wall is full of brackets. The process is more complicated, takes up a lot of spa

Abstract

The invention relates to a construction method of a self-supporting single-side formwork erecting system of an ultrahigh exterior wall of a basement. The construction method mainly includes the steps of preparation before construction, anchor rod lengthening, cushion wood laying, standard combined steel formwork construction, double-channel-steel cross brace construction, profile-steel triangular support construction, screw fixing, upper portion fixing, concrete pouring, formwork demounting and repairing. The construction method is suitable for a high formwork of the exterior wall of the basement, especially high formwork construction with single-side formwork erecting of the basement. The self-supporting single-side formwork erecting system is high in waterproofness and stability, many holes generated in conventional formwork erecting methods are reduced, construction efficiency is improved, and the construction method has high technical and economic benefit.

Description

technical field [0001] The invention relates to a construction method of a self-supporting single-side formwork system for a super-high outer wall of a basement. It is suitable for the high formwork construction of the basement exterior wall, especially the high formwork construction of the basement with one-side support formwork. The self-supporting single-side formwork system of the super-high outer wall of the basement of the present invention has good waterproofness and stability, reduces many holes produced by traditional formwork methods, improves construction efficiency, and has better technical and economic benefits. Background technique [0002] Our country generally adopts the method of double-side support formwork of the pull screw rod for the construction of building walls. In the construction of basement walls, due to the development of the enclosure structure, the distance between the basement exterior wall and the support structure is very limited. In some ca...
