Method for adjusting axis deviation of industrial factory building edge foundation heavy column

Abstract

The invention relates to a method for adjusting the axis deviation of an industrial factory building edge foundation heavy column, which comprises the following steps of: (1) hoisting a heavy column into an edge foundation; (2) measuring the verticality and the axis deviation of the heavy column by using a theodolite; and (3) adjusting the axis deviation of the heavy column. The axis deviation adjustment of the heavy column comprises the following steps of: firstly, vertically and fixedly installing vertical steel plates on both ends of the heterotopic surfaces of a horizontal rectangular steel plate respectively for forming a base; reclining the vertical steel plate at one end of the base and the horizontal steel plate to the inner wall and the top surface of the convex part of the edge foundation; reclining a jack base on the vertical steel plate at the other end of the base and attaching the end part of a push rod of a jack to the outer wall of the heavy column; controlling the jack to finish the axis deviation adjustment of the heavy column; and fixing by using a steel wedge with corresponding size. The adjusting method has the advantages of simple and easy operation, high operating safety, attractive edge foundation appearance, higher precision, effective improvement on the construction quality, shortening of the construction time and improvement on the construction efficiency.

Description

technical field [0001] The invention belongs to the field of construction, in particular to a method for adjusting the axis deviation of a heavy-duty column at the cup base of an industrial factory building. Background technique [0002] In the installation and construction of industrial plant structures, large-scale steel pipe lattice columns or reinforced concrete solid web columns are generally heavy-duty columns. When installing on a rectangular or square cup-shaped foundation, the axis deviation adjustment of the heavy-duty columns is usually done by hammering Make adjustments with steel wedges, that is, hoist the heavy-duty columns into the cup-mouth foundation with a square cross-section. After the steel wire rope is loose, measure the verticality of the heavy-duty columns with theodolite, and then put the steel wedges into the heavy-duty columns and the four walls of the cup-mouth foundation. Hit the steel wedge with a sledgehammer to adjust the axis deviation of the...

[0002] In the installation and construction of industrial plant structures, large-scale steel pipe lattice columns or reinforced concrete solid web columns are generally heavy-duty columns. When installing on a rectangular or square cup-shaped foundation, the axis deviation adjustment of the heavy-duty columns is usually done by hammering Make adjustments with steel wedges, that is, hoist the heavy-duty columns into the cup-mouth foundation with a square cross-section. After the steel wire rope is loose, measure the verticality of the heavy-duty columns with theodolite, and then put the steel wedges into the heavy-duty columns and the four walls of the cup-mouth foundation. Hit the steel wedge with a sledgehammer to adjust the axis deviation of the heavy-duty column. Hitting the steel wedge will easily cause damage to the foundation concrete of the cup mouth, making the foundation unstable and affecting the quality of the entire project; 2. It is difficult to control the accuracy of the axis deviation adjustment of the entire heavy-duty column, and the construction time is long and the efficiency is low; 3. Large The safety of hammering the steel wedge operation is poor; 4. The appearance of the base of the cup mouth is poor, which affects the aesthetics
