Method of Realizing Building Shifting and Steering by Adjusting Roller Diameter

Abstract

The invention discloses a method for realizing displacing and steering a building through adjusting diameters of rolling shafts. The steering is completed through changing the diameters of the rollingshaft before and after displacement; the direction adjustments of the rolling shafts are completed without being jacked by a jack; the additional internal force generated by the deformation caused bythe jacking is avoided; concrete for underpinning beams before and after the steering is simultaneously poured; moreover, the bottom elevations of before-steering and after-steering beams and the topelevations of tracks are consistent; the construction is convenient; the construction period is shortened; the before-steering concrete underpinning beams are mildly destroyed when the rolling shaftsare taken out, but the displacement after the steering is not influenced.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a method for realizing shifting and turning of a building by adjusting the diameter of a roller. Background technique [0002] Generally, in order to reduce the friction force in the displacement, the roller is used as the walking device. Before the building is shifted, shift tracks are built on both sides of the column (wall), steel rollers are laid on the shift rails, and channel steel is supported on the steel rollers as the bottom formwork pouring to make reinforced concrete underpinning beams and underpinning beams The columns (walls) are clamped on both sides, and connected to the columns (walls) by planting bars. Before the displacement, the connection between the column (or wall) and the foundation is cut off, and the load transfer path of the upper part of the building is changed from passing through the column (or wall) and foundation to the foundation before...

Problems solved by technology

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; in addition, in addition to the traction device, a jacking device (jack) is required, which increases the construction cost

In the steering method for building displacement disclosed in Chinese patent ZL201210193925.3, after the building is shifted to the steering position, the shifting track after the steering is poured. Although the use of jacking equipment is avoided, the displacement after the pouring is The track concrete needs to be cured for a long time (usually after 28 days to reach 100% design strength), thus delaying the precious construction period

Chinese patents ZL201610695054.3 and ZL201610685861.7 realize the displacement of the building by climbing up the slope to raise the concrete underpinning beam after turning or lowering the shifting track after turning, but the underpinning beam or track before and after turning is not at the same elevation, which will cause damage to the components. Concrete supporting formwork, etc. cause difficulties
