Building displacement turning method

Abstract

The invention discloses a building displacement turning method. The building displacement turning method comprises the following steps: (1) pouring and manufacturing a turning front displacement railway, a turning rear displacement railway and a turning front support exchanging beam before the displacement on a building which needs to turn; (2) cutting off a column or a wall from a foundation so as to transfer to the turning position through a traction or pushing gear; (3) paving steel rolling shafts on the turning rear displacement railway, and supporting a channel steel on a steel rolling shaft to be used as a bottom template to pour and manufacture the turning rear support exchanging beam; (4) cutting the channel steel adjacent to the rolling shaft arranged below the turning front support exchanging beam, taking out the rolling shafts, changing the transmission pipeline of the building load from the displacement front support exchanging beam, the displacement front rolling shafts and the displacement front railway to the displacement rear support exchanging beam, the displacement rear rolling shafts and the displacement rear railway; and (5) installing the traction or pushing gear after displacement, and continuing with the displacement. The building displacement turning method provided by the invention does not need a lifting jack to jack to complete the rolling shafts turning, thereby avoiding additional internal force generated by jack deformation; the rolling shafts are paved on a turning rear railway so as to manufacture a turning rear support exchanging beam, the beam bottom deformation is small, the flatness is high, and the building displacement turning method is beneficial for displacement.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a method for shifting and steering a building. Background technique [0002] At present, during the process of building relocation, sometimes the predetermined location cannot be reached at one time, and it needs to be turned in the middle to be successfully in place. If the weight of the building is relatively light, the sliding block is used as the walking device, and only the direction of the traction device needs to be changed, and the steering can be completed smoothly without handling the sliding block. And adopt roller or tackle as walking device, because roller or tackle can only move to single direction, turn to problem and just become complicated. [0003] For the usual building shifting, shifting tracks are built on both sides of the column (wall), steel rollers are laid on the shifting rails, channel steel is supported on the steel rollers as a bottom formw...

Problems solved by technology

However, if the underpinning beam after the steering is cast at the same time as the underpinning beam before the steering, there will be the following two problems: (1) The bottom formwork of the underpinning beam after the steering cannot be supported on the steel roller

The top support of the bottom formwork of the underpinning beam after turning will be directly supported on the foundation soil. If the foundation deformation is large, the bottom of the underpinning beam after turning will be uneven, which will seriously affect the displacement and movement after turning.

(2) When traveling to the steering position, it is also difficult to place the rollers under the underpinning beam after steering and take out the rollers under the underpinning beam before steering

The disadvantage of this method is that the jacking will generate additional internal force in the underpinning structure and the upper structure, which will cause cracking in severe cases
