Reverse building method steel pipe column accurate installation and adjusting device and using method

Abstract

The invention relates to the field of building construction, and particularly discloses a reverse building method steel pipe column accurate installation and adjusting device. The device comprises a positioning frame which is located at a pile hole and is provided with a cavity. The left side wall and the right side wall of the cavity are both slidably connected with sliding blocks. A first hydraulic cylinder is fixed to the front side wall of the cavity. Cross bars are fixed between the sliding blocks. The cross bars are slidably connected with a positioning block. The first hydraulic cylinder is fixed to the side walls of the sliding blocks. A round hole is formed in the positioning block. A perpendicularity adjusting structure is arranged in the round hole and comprises a first annularblock. The side edge of the first annular block is fixed to a first connecting rod. A groove is formed in the positioning block. A second annular block is arranged in the first annular block. The sideedge of the second annular block is fixed to a second connecting rod. A third annular block is fixed to the second annular block. A fourth annular block is arranged in the pile hole. An annular railis fixed to the fourth annular block, and a third hydraulic cylinder slides on the annular rail. The device aims to solve the problem that reverse building method supporting columns are low in perpendicularity accuracy and high in column top elevation error.

Description

technical field [0001] The invention relates to the technical field of building construction, and specifically discloses a device for precise installation and adjustment of a steel pipe column by a reverse method and a method for using it. Background technique [0002] With the leap-forward development of my country's comprehensive national strength, urban construction is in the ascendant, and limited by the scarcity of land, in urban construction, the development and utilization of underground space is getting more and more attention. Due to its distinct advantages, the reverse construction method is being widely adopted and used in the development and utilization of underground space. As the load-bearing structure in the reverse operation stage, the construction quality of the support column in the reverse operation method is very important. However, for a long time, the control of the verticality, elevation and column position of the supporting column in the reverse meth...
