Sinking restoration structure for steel structure room and restoration method thereof

Abstract

The invention relates to the technical field of steel structure rooms, and in particular relates to a sinking restoration structure for a steel structure room and a restoration method thereof. The sinking restoration structure for the steel structure room includes a steel column as the support body of the steel structure room, the steel column includes cross columns and a longitudinal column, the steel column is fixed on the column bottom plate which is rectangular in shape, the column bottom plate is arranged on the column base, the column base includes a central area positioned right below the column bottom plate and an extending area positioned at the periphery of the center area, a restoration jacking device is arranged above the extending area, a jacking traction leg is arranged at the upper end of the restoration jacking device, the jacking traction leg is also fixedly connected with the steel column, foundation bolts are arranged on the column bottom plate, plumb bobs are arranged at intervals at the middle parts of the cross and longitudinal columns in vertical direction, and a dial indicator is connected with the jacking reaction leg. According to the sinking restoration structure, the restoration method that the restoration jacking device is used for driving the steel column by the jacking traction leg to move upwards, thus being firm and stable in structure, conductive to restoring after the steel structure room sunk, low in cost, simple in technology and good in restoration effect.

Description

technical field [0001] The invention relates to the technical field of steel structure houses, in particular to a sinking reset structure and a reset method for a steel structure house. Background technique [0002] In the prior art, there are more and more types of steel structure houses, and among them, the utilization rate of steel structure industrial buildings is greatly improved, because of its small steel consumption, small foundation load, large span, high space utilization efficiency, and low comprehensive cost. Flexible plane layout and convenient suspension have been widely used in recent years. However, due to factors such as uneven settlement of the foundation soil or quality problems of foundation treatment, the concrete column foundation at the lower part of the plant makes the steel column and steel structure The factory building sinks as a whole, and if it is serious, it will collapse. If the original demolition and reconstruction are used, it will cost mon...

AI Technical Summary

Problems solved by technology

[0005] In the above technical proposal, the steel structure can be used for the steel column and the slab at the bottom of the column, and the structure body can be cast with concrete for the column base, and the steel structure house can sink and reset When the structure is in normal use in the steel structure house, the reset jacking device, jacking traction leg, wire hammer and dial indicator can be removed, but in the process of using the steel structure house in the reset stage, it is necessary to locate and set up these structures. When the steel structure building sinks and needs to be reset, the entire reset structure will play a very important role. Not only the whole structure is firm and stable, but also the construction process of the reset process of the house body is simple, the equipment is compact, the construction period is short, and the construction cost is low. , The biggest advantage is that the production in the factory does not need to be stopped during the construction process, the original structure is not damaged, and the safety and reliability are strong. It completely solves the problem of high cost of demolition and reconstruction, and wastes money. The reset jacking device is used to drive the jacking leg The jacking method of raising the steel column replaces the original demolition and reconstruction In order to solve this contradiction, the construction efficiency is effectively improved with the smallest investment and the most convenient and practical construction method
