Integer lifting technique for house

Abstract

The invention discloses a process for integrally elevating the rooms of a low-course building. Wherein, the quantity, interval and locations of the lifting supports are determined depending upon the load pressure of the part to be elevated; an integral gird is formed by solidifying the truss on the surrounding wall along a reference line; holes are dug at certain interval under the integral gird, two lifting supports are arranged in each hole; the wall reserved under the integral gird is cut open by a cutter, meanwhile the lifting supports are elevated synchronously; after elevating to certain height, the lifting supports are removed in an alternative way in each hole, and the wall is re-built; the upper part of the building is matched with the lower part of the building; the wall is re-built at the location where the removed lifting supports are; expansion concrete is filled full and compact into the gaps between the upper and lower walls, now the elevation of the building is completed. The invention is featured by steady elevation of rooms, is capable for correcting the positional shift of upper and lower wall, and not liable to tilting, etc.

Description

Technical field: [0001] The invention belongs to the technical field of overall elevation of low-rise buildings, in particular to an overall elevation process of houses. Background technique: [0002] With the development of urban construction planning, due to the heightening of the street surface, the elevation of the original building ground floor will be lower than the elevation of the road surface or drainage, causing rainwater to flow back and the ground to be wet, and domestic sewage cannot be discharged. If the indoor floor is increased, The height of the indoor roof is obviously reduced, which cannot meet the requirements of use. There are also some old buildings that cannot meet the requirements for space height due to the increasing development of people's life due to their low floor height. Meet the requirements for use. At present, the overall house raising technology is: firstly, the walls around the building are reinforced to form ring beams, holes are dug at...

Problems solved by technology

When the support is pressurized and starts to rise, due to the better bonding performance of the wall in some parts, the pressure on each hydraulic support will be different, and the bottom wall of some supports will be cracked and deformed, which is not stable enough; on the other hand, if The position of the building is shifted after it is raised, and it cannot be adjusted conveniently, resulting in a certain error in the position of the upper and lower walls; Uniform settlement, resulting in slight inclination of the house
