Description

Quick and safe installation and positioning component and installation method of a cup mouth column

technical field

The invention relates to the technical field of building construction, and more particularly, to a quick and safe installation and positioning component and an installation method of a cup mouth column.

Background technique

For the installation of the base column of the cup mouth, after the column is inserted into the cup mouth, it is necessary to precisely adjust and control the axis position, elevation, and verticality of the column plane. If there is any deviation in any item, the column cannot be positioned, and the acceptance will fail to pass and enter the next process . In addition, general column hoisting is a highly dangerous operation. After the lifting equipment is hoisted to the mouth of the cup, the position and elevation need to be adjusted continuously to meet the requirements of the column installation required by the code. The entire installation process may last for several hours. It is particularly urgent for faster, more accurate and efficient installation of the cup column, which can save a lot of labor and mechanical shift costs, and also reduce safety risks. Column components are generally the largest and heaviest components in each structure, and it is basically difficult to adjust them only by manpower. Therefore, in conventional installation, on-site operators and management personnel will process and make auxiliary tools such as wedges according to the actual situation to assist in coordination. Manual column installation speeds up the installation process. However, traditional tools have problems such as time-consuming and labor-intensive, and low installation accuracy.

The Chinese utility model patent with the application number CN202020673342.0 discloses a base column installation assembly for the cup mouth, including a first positioning part arranged on the lower end surface of the center column of the cup mouth; a second positioning part arranged on the upper surface of the cup mouth The port; the first positioning part restricts the upright column from moving forward and backward in the cup opening; the second positioning part adjusts the position of the upright column in the cup opening left and right. This solution solves the time-consuming and labor-intensive installation process of the cup foundation column due to the use of wedges to adjust the position of the X-axis and Y-axis when the cup mouth size is slightly larger than the size of the column in the installation of the cup foundation column, and the installation accuracy is low. Technical problem, however, the second positioning part of this scheme has less safety measures, and it is easy to cause the oil cylinder to skew and hurt people when pushing, and this scheme cannot adjust the verticality of the column.

Therefore, it is a technical problem to be solved urgently to develop a fast and safe installation positioning component and installation method of the cup mouth column.
