Problems solved by technology

[0002] The cross-shaped steel concrete column is a commonly used form in steel concrete (SRC) structures. Due to the advantages of high bearing capacity, high rigidity and good seismic performance of this structural form, it has been more and more used in long-span structures and High-rise buildings and super high-rise buildings in earthquake areas, but the installation process of cross-shaped steel columns is relatively complicated, which increases the workload, resulting in slow construction progress and increased construction costs, which is not conducive to effective construction

Embodiment Construction

[0031] Construction technology of the present invention is as follows:

[0032] The first step is to measure and mark the cross axis of the steel column to be installed. The cross axis is used as the basis for the installation and positioning of the steel column and the control of installation parameters;

[0033] The second step is to check and check the shape and size of the steel column to be installed, the model of the steel column, and whether it is deformed during transportation;

[0034] The third step is to vertically lift the verified upper and lower section steel columns to the installation site with a lifting machine, and place a circle of steel bars with a diameter of 6mm at the joint of the upper and lower section steel columns to reserve adjustment space;

[0035] Step 4: After hoisting the upper and lower section steel columns in place, install ear plates outside the flange plates of the upper and lower section steel columns, clamp the ear plates with connecting...

Abstract

The invention belongs to the field of building construction, in particular to a construction technology of a cross-shaped profile steel column, comprising the following steps: firstly laying off and identifying the cross-shaped axes of a profile steel column to be installed, and using the cross-shaped axes as a reference for installing and positioning the profile steel column and controlling the installation parameters; checking and verifying the dimension and model of the profile steel column to be installed and whether the profile steel column is deformed or not in the transport process; and vertically hoisting the verified profile steel column with an upper section and a lower section to an installation position by utilizing a hoisting machinery, placing a ring of steel bar with the diameter of 6mm at the butt part of the upper section and the lower section of the profile steel column, and reserving a space for regulation. The construction technology in the invention has simple construction procedures and is favor of safe management.

Description

Technical field: [0001] The invention belongs to the field of building construction, and in particular relates to a construction technology of a cross-shaped steel column. Background technique: [0002] The cross-shaped steel concrete column is a commonly used form in steel concrete (SRC) structures. Due to the advantages of high bearing capacity, high rigidity and good seismic performance of this structural form, it has been more and more used in long-span structures and For high-rise buildings and super high-rise buildings in earthquake areas, the installation process of cross-shaped steel columns is relatively complicated at present, which increases the workload, resulting in slow construction progress and increased construction costs, which is not conducive to effective construction. Invention content: [0003] The object of the present invention is to overcome the deficiencies in the prior art and provide a cross-shaped steel column construction process with simple pr...
