Formwork combination reinforcing and supporting structure used in short-leg shear wall construction and construction method thereof

Abstract

The invention relates to a formwork combination reinforcing and supporting structure used in short-leg shear wall construction and a construction method thereof. The structure comprises formworks used for pouring a longitudinal short-leg shear wall and a transverse short-leg shear wall and split bolts between the formworks, and back supports of the formworks are composed of secondary edges and primary edges. The structure further comprises a plurality of horizontally arranged wall hoop bolts in the height direction of walls on the peripheries of the longitudinal shear wall formwork and the transverse shear wall formwork, wherein the wall hoop bolts are used for connecting and reinforcing a whole formwork enclosure system and the ends of the wall formworks in a tensioning mode. The lower portion of the formwork enclosure system is fixedly connected with short bolts pre-buried in last process, and tensile-connection bottom sealing is formed. For installation of the formworks of the short-leg shear walls, the structures of the formworks themselves are used in combination with the wall hoop bolts, therefore, the stability of a short-leg shear wall formwork supporting system is enhanced, the accuracy of the formworks in horizontal position and structure size is guaranteed, the effects on formwork supporting and reinforcement are achieved, and the purpose of lowering manufacturing cost is realized.

Description

technical field [0001] The invention relates to a formwork support structure and a construction method thereof in construction engineering, in particular to a formwork combination reinforcement support structure and a construction method used in the construction of a short-limb shear wall structure. Background technique [0002] In construction projects, the stability of short-leg shear wall formwork is more prominent, and the construction is more difficult. At present, the traditional formwork support method adopts construction fasteners to fasten the back of the steel pipe or installs tool-type step-by-step reinforcement methods at the end of the wall, which cannot solve the overall stability of the formwork. In addition, there is also the problem that the upper formwork is not firmly fixed at the position of the outer wall of the building and the stairwell wall. Due to the joint action of the concrete load and the construction load during construction, formwork deformatio...

Problems solved by technology

At present, the traditional formwork support method adopts building fasteners to fasten the back of the steel pipe or installs tool-type step-by-step reinforcement methods at the end of the wall, which cannot solve the overall stability of the formwork.

In addition, there is also the problem that the upper formwork is not firmly fixed at the position of the outer wall of the building and the stairwell wall. Due to the joint action of the concrete load and the construction load during construction, formwork deformation, displacement, and existing joints are prone to occur, resulting in the quality of the concrete structure. bad question
