Building pillar removing device and method

Abstract

The invention discloses a building pillar removing device and method. The building pillar removing device and method aim to overcome the defects that after existing house building pillars are removed, the influence on the structural strength of a house is large, the supporting strength at the pillar removing position of the house is lowered, and then the service life of the house is shortened. Before the pillars are removed, surrounding pillars and a cross beam or a floor need to be subjected to prestress concrete reinforcement, prestress steel strands are installed in prestress concrete, and each prestress steel strand penetrates through self-locking sleeves on self-locking plates and then the self-locking sleeves are backwards compressed; then jacking hydraulic cylinders are installed on the self-locking plates, and each prestress steel strand penetrates through locking sleeves on jacking plates and the locking sleeves are backwards compressed, so that the prestress steel strand is tightly clamped in the locking sleeves; and the jacking hydraulic cylinders at the two ends of the steel strands are started synchronously and push jacking pistons to outwards tension the prestress steel strands, and when it is detected that pressure borne by the pillars to be removed is within the safety removing range, the pillars to be removed are cut off and removed.

Description

technical field [0001] The present invention relates to a building maintenance technology, more specifically, it relates to a building column removal device and method. Background technique [0002] There are many pillars in many houses and buildings. The pillars play a good role in supporting the house and ensuring the structural strength and stability of the house. However, sometimes too many pillars will not only block the line of sight, but also reduce the use of the house. Space, especially in some halls of houses, at this time, many householders will choose to remove a few pillars to achieve a better use of the house, but the pillars are the lifeblood of the house, directly remove the structure that affects the house, and reduce the use of the house life. At present, more methods are used to support the floor and beams around the columns to be removed, and then disassemble the columns. After processing the floors and beams at the positions where the columns are remove...

AI Technical Summary

Problems solved by technology

Although removing the pillars in this way increases the space of the house and improves the utilization effect of the house, but the support strength of the position decreases after the pillars are removed, which affects the service life of the house
