Temporary facility for structure dismantling and rebuilding and construction method thereof

Abstract

The invention relates to a temporary facility for structure dismantling and rebuilding and a construction method thereof. The temporary facility comprises an indoor steel frame supporting system, an outer wall steel hoop and angle steel which are mounted on an existing wall. The indoor steel frame supporting system comprises steel frame supporting columns, steel frame supporting beams, truss typevertical diagonal bracings and truss type horizontal diagonal bracings; the steel frame supporting columns are vertically mounted on strip-shaped foundation beams; the steel frame supporting beams arehorizontally erected among the steel frame supporting columns; and the truss type vertical diagonal bracings and the truss type horizontal diagonal bracings are fixed to the steel frame supporting columns or the steel frame supporting beams in a crossed mode correspondingly. The angle steel connects the indoor steel frame supporting system with the outer wall steel hoop. The existing wall is reinforced temporarily by adopting the indoor steel frame supporting system and the outer wall steel hoop, so that the stability and safety of the existing wall are well ensured in the dismantling and rebuilding transformation process of a brick-concrete structure.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a temporary facility for structure demolition and reconstruction and a construction method thereof. Background technique [0002] During the demolition and reconstruction of brick-concrete structures, in order to ensure the safety and stability of the structural system, support systems such as wooden structures, steel pipe scaffolding, and pre-stressed steel structures are usually used to construct temporary supports layer by layer from bottom to top. With the reconstruction of the structure, the temporary supports are removed layer by layer from bottom to top. Temporary supports for wooden structures have the advantages of convenient material acquisition, low cost, and flexible layout, but their bearing capacity is low and they are prone to instability. It is difficult to form a stable anti-lateral system in the reconstruction of super-long and super-high structures, and its...

AI Technical Summary

Problems solved by technology

Temporary supports for wooden structures have the advantages of convenient material acquisition, low cost, and flexible layout, but their bearing capacity is low and they are prone to instability. It is difficult to form a stable anti-lateral system in the reconstruction of super-long and super-high structures, and its application is limited. ; The steel pipe scaffolding support system has a large bearing capacity, convenient assembly and disassembly, and flexible erection, but the erection distance is relatively dense, and it is difficult to provide sufficient operating surfaces for subsequent corresponding processes; the rigid steel structure supports have excellent mechanical properties and are installed in a small number. The actual installation and disassembly is convenient, but the installation and disassembly process requires a large operating surface, and it is not suitable for use in the dismantling and reconstruction of small space structures
