Embodiment Construction

[0013] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] Please combine Figure 1 ~ Figure 3 As shown, the limit force transmission device for building jacking of the present invention is arranged on the bottom column or pier column 1 of the building or bridge. The limiting force transmission device includes a lattice column, the bottom of which is fixed on the ground or the platform, and forms a rectangular limiting frame fixed on the outside of the bottom column or pier column 1 . The above-mentioned lattice columns can be divided into two types: panel type and strip type. figure 1 Shown is a panel-type lattice column 10a, which includes a split angle steel 11a and a horizontal section steel 12a for connecting the split angle steel, and the four split angle steels 11a are respectively arranged at the four corners of the bottom column or pier column 1 , the inner side of e...

Abstract

The invention discloses a displacement limit force transmission device for jacking up a building. The device comprises lattice columns, wherein the bottoms of the lattice columns are fixed on the ground or a bearing platform and form a displacement limit frame fixedly arranged on the outer part of a bottom layer column of the building or the outer part of a pier column of a bridge. Therefore, the jacked-up building or bridge can only vertically move upwards in the lattice columns; and once the building or bridge has a trend of conducting longitudinal / lateral displacement on the horizontal plane, branch angle steel can limit the displacement trend and transmits the horizontal force to the whole lattice columns until the bearing platform through horizontal section steel or oblique section steel, so that a displacement limit effect can be well achieved.

Description

technical field [0001] The invention relates to a building jacking auxiliary device, in particular to a limit force transmission device for building jacking. Background technique [0002] At present, when a building or bridge is lifted, the building or bridge is prone to horizontal longitudinal and lateral displacement and horizontal deflection, which must be limited, otherwise it will be difficult to correct once the displacement occurs, and there will be safety hazards . The traditional limit method is centralized limit, that is, when the building or bridge is lifted, the overall structure of the building or bridge is limited. Specifically, steel structures or concrete structures are fixed and restricted at the four corners of the overall structure, so as to prevent horizontal longitudinal and lateral displacement of buildings and bridges, and overcome the horizontal force acting on buildings or bridges. However, there are shortcomings such as excessive pressure acting o...
