Abstract

The invention belongs to the field of steel structure buildings, and in particular relates to a hydraulic jacking system with bottom joints and a construction method. The jacking system is composed of a jacking reaction frame, an anti-overturning stable frame, a standard joint of the jacking frame and a top platform. During the jacking process, as the jacking height continues to increase, the anti-overturning stability of the entire jacking system will decrease. By setting the anti-overturning stabilizer, the jacking system will always maintain the release of the vertical translational freedom during the jacking process. The directional translation and rotation degree of freedom constraints improve the anti-overturning stability of the entire jacking system, and the jacking beam is connected to the standard joint of the jacking frame through a pin connection, which improves the efficiency of jacking construction.

Description

technical field

[0001] The invention belongs to the field of steel structure buildings, and in particular relates to a hydraulic jacking system with bottom joints and a construction method. Background technique

[0002] At present, the construction of large-scale space steel structure roof mainly includes component installation method, block hoisting method, cumulative slip method, integral / block cumulative lifting method and jacking method, among which jacking method is a fast and efficient construction method. The method is often used in the construction of large space steel structure roofs with a small construction height (15m-20m).

[0003] However, the existing conventional jacking methods are divided into two categories: one is the combination of temporarily assembled jacking frames and jacks, and the joint method is bottom joints; the other is the use of strip pads and square pads and jacks. Combination, the purpose of jacking is achieved by continuously increasing t...

Embodiment Construction

[0024] The following will be combined with Figure 4 , 5 And embodiment, the present invention is described in further detail.

[0025] In the embodiment of the present invention, the jacking system consists of jacking reaction frames (1, 2, 5), anti-overturning stabilizers (3), jacking frame standard sections (4, 6) and top supporting well-tac-toe platforms (9, 10, 11) composition. The jacking reaction frame is composed of the bottom well-shaped beam 1, the hydraulic jack 2 and the jacking beam 5; the anti-overturning stable frame 3 is composed of a vertical rod A and two horizontal connecting rods B in the height direction, and the rods are all made of circular tube sections; The standard section (4, 6) of the jacking frame adopts a rectangular section form, and is formed by connecting several standard sections with flanges 8 . The standard section is composed of two finished plane trusses 6 and the connecting angle steel 4 between the trusses. The angle steel and the fin...
