A method for overall shifting of a building by using an assembled trailer

Abstract

The invention relates to a method for overall displacement of a building by using an assembled trailer. When the building is completely placed on the trailer chassis, the vertical load and the vertical load applied to each jack of the trailer chassis by the building and the underpinning structure are calculated. For the difference in lifting force of the corresponding jack to the building, a counterweight is placed on the chassis of the trailer near the corresponding jack to balance the difference. Since the jacking force of the trailer on the building is a force evenly distributed along the trailer chassis, the supporting force on the building is uniform, and the structure of the building is different, so the force applied to different positions of the trailer chassis is different, so the building The direction of the resultant force received by different parts is different, so it is easy to generate shear stress inside the building. In the present invention, the counterweight is added to the position where the load of the building is applied to the chassis of the trailer, so that the chassis of the trailer is subjected to a uniform downward pressure. Furthermore, the shear stress inside the building is eliminated, the damage of the shear stress to the building is avoided, and the purpose of safe displacement is realized.

Description

technical field [0001] The invention relates to the field of civil construction, in particular to a method for overall shifting of a building by using an assembled trailer. Background technique [0002] At present, building relocation technology is to relocate the existing buildings to new sites as a whole, which solves the contradiction between demolition and preservation in urban development, and protects historical buildings with cultural relics value. For tall shifting buildings, before the building shifts, it is necessary to cut off the superstructure and the foundation through structural underpinning, so that the load of the superstructure is transferred to the underpinning structure, and the running device (roller shaft) is placed between the underpinning structure and the track. , slider or pulley) to form a movable building, and then moved to the position by the traction device. This method needs to lay the foundation and track from the original site to the new sit...

AI Technical Summary

Problems solved by technology

Due to the lack of special trailer equipment for the existing trailer shifting, and the trailers loaded with industrial equipment are mostly used, there are problems such as matching between buildings and trailers.

Especially when the building bottom area is large and several trailers are needed for assembly and transportation, the vertical load of different parts of the building will be inconsistent with the jacking force of the corresponding parts of the trailer, which will cause additional shear stress in the load-bearing components of the building, seriously cause cracking of the component
