Portable sheet-shaped flexible jacking device applied to jacking deviation rectification of building

Abstract

The invention discloses a portable sheet-shaped flexible jacking device applied to jacking deviation rectification of a building. The portable sheet-shaped flexible jacking device is characterized inthat a honeycomb-shaped deformation body is composed of honeycomb laminates which are sequentially stacked from top to bottom, honeycomb holes which are uniformly distributed at intervals are correspondingly formed in each honeycomb laminate, the honeycomb holes of two adjacent honeycomb laminates are staggered, all honeycomb holes of the honeycomb deformation body are in communication with one another to form a jacking pressurizing chamber, and all the honeycomb laminates are extruded into an integrated structure; and a deformation body bottom plate is ultrasonically welded to the lower surface of the honeycomb-shaped deformation body, deformation body side plates are ultrasonically welded to the left, right, front and back of the honeycomb-shaped deformation body correspondingly, a deformation body flexible top plate is ultrasonically welded to the upper surface of the honeycomb-shaped deformation body, and a pressurizing valve is arranged on the deformation body flexible top plate.The portable sheet-shaped flexible jacking device has the advantages of being light in weight, low in initial height, low in requirement for a jacking interface, large in jacking height ratio and ideal in jacking effect.

Description

technical field [0001] The invention relates to the technical field of building jacking rectification, in particular to a portable sheet-shaped flexible jacking device applied to building jacking rectification. Background technique [0002] In the current construction projects, buildings such as frame structures, masonry structures, bridge structures, etc., due to the complexity and uncertainty of the soil layer of the building foundation, most buildings are built on uneven soil layers, and are subject to Under the influence of long-term dynamic load, ground motion or self-weight, the building will be inclined to different degrees or unevenly settled, which will lead to the cracking of local components of the building, which will affect the use function of the building, and eventually develop into a Complete loss of function or collapse of the building. Therefore, on the basis of good conditions, the building is corrected by jacking up, so that the building can be straighte...

AI Technical Summary

Problems solved by technology

In the actual jacking and rectification process, the positioning, installation and withdrawal of the jacking equipment is more cumbersome. The reason is that the jacking equipment is usually a jack, which is heavy and needs to be recycled. The ratio is small, the interface strength and flatness of the jacking part are high, and the working stability is poor; this affects the progress and safety of jacking and deviation correction to a certain extent

[0004] It should be further pointed out that due to the large weight and volume of traditional jacking equipment and high requirements on the jacking working surface, the distribution of jacking equipment is relatively discrete. The limitation of the lifting device, and the stress concentration deformation of the jacking part is easy to occur; in addition, the uncoordinated deformation of the jacking equipment may easily lead to cracking of the building structure

Therefore, the use of rigid jacking equipment will cause the problem of unsatisfactory jacking effect of the structure
