Formwork supporting structure

Abstract

The invention discloses a formwork supporting structure which is used for being arranged on an outer wall pouring formwork of a basement. The formwork supporting structure comprises a plurality of vertical fixing pieces arranged in the outer wall pouring formwork at intervals in the horizontal direction, a plurality of horizontal fixing pieces and a plurality of first split bolts, wherein one end of each vertical fixing piece is connected with a bottom plate of the basement; the horizontal fixing pieces are arranged in the outer wall pouring formwork at intervals in the vertical direction, and the horizontal fixing pieces are connected with any one of the vertical fixing pieces; one end of each first split bolt is connected with the horizontal fixing piece, and the other end of each first split bolt is connected with one side of the outer wall pouring formwork in a pulling mode. According to the method, fixing is conducted from the side, back to the concrete retaining wall, of the outer wall pouring formwork through the first split bolts, the occupied space is small when fixing is conducted through the method, and meanwhile problems that an embedded steel bar head in the bottom plate needs to be cut off and repaired in the later period are solved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a formwork support structure. Background technique [0002] As more and more underground space resources are developed and utilized, how to rationally develop and utilize deep and large foundation pits is becoming more and more important. During the construction of the basement, there may be situations where the supporting structure is too close to the basement outer wall structure, which makes the construction of the basement outer wall difficult. At present, in view of the situation that the support structure is relatively close to the basement exterior wall, the existing construction methods mostly adopt unilateral formwork support (external support) on the inner side of the basement exterior wall, that is, the inner side of the basement exterior wall adopts throw braces to form a support system. Using this method to support the system takes up a lot of space, a...
