Temporary back-jacking support construction method

Abstract

The invention discloses a temporary back-jacking support construction method which comprises an upper-layer structure needing back-jacking support and a cured lower-layer structure, a supporting device is unfolded on the surface of the lower-layer structure, and the supporting device is composed of a top plate, a supporting column, a lifting device and a base from top to bottom. The top plate is fixedly connected with the supporting column, the supporting column is fixedly connected with the lifting device, and the lifting device is fixedly connected with the base. The problems that a traditional temporary back-jacking supporting method is difficult to assemble and inconvenient to disassemble are solved, the novel temporary back-jacking supporting construction method which is convenient to assemble and disassemble and adjustable in height is provided, manpower and material resources are greatly saved, and the construction efficiency is improved.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a construction method suitable for temporary backing support. Background technique [0002] Back support is widely used in construction. For example: when the beam slab at the post-casting belt is demolished, the post-casting belt part needs to be backed up in time; the base tower crane needs to be backed up; the construction elevator is arranged on the basement roof, and each floor below the basement needs Carry out roof backing; the discharge port on the basement roof needs to be backed up; the driving route and material equipment storage yard set on the basement roof need to be backed up. In these places, due to the self-weight of the structure, the large span of the structure, and the large load on the structure, if the support is not supported or the top is not returned in time, the structure will deflect and deform and produce tiny cracks, which will affect ...

AI Technical Summary

Problems solved by technology

In these places, due to the self-weight of the structure, the large span of the structure, and the large load on the structure, if the support is not supported or the top is not returned in time, the structure will deflect and deform and produce tiny cracks, which will affect the durability of the structure, and even cause structural damage. Destruction leads to safety production accidents

The traditional backing support methods mainly include the full backing of vertical poles and the backing up of partial steel or concrete columns. The former supports a lot of work, while the latter is complex to calculate and inconvenient to dismantle later.
