High-altitude integral slide device for jacking platform and construction method

Abstract

The invention discloses a high-altitude integral slide device for a jacking platform and a construction method. The method comprises the steps that the slide device is placed in corbel holes of a major structure, and the slide device comprises first slide bodies and second slide bodies slidably arranged above the first slide bodies; box beam corbels of the jacking platform are compacted on the second slide bodies; and ejection devices are installed between the box beam corbels and the major structure and started to eject the jacking platform to move along the slide tracks of the first slide bodies and the second slide bodies. According to the high-altitude integral slide device for the jacking platform and the construction method, the slide device is placed in the corbel holes and horizontally adjusts the displacement of the box beam corbels of the jacking platform placed on the slide device, so that high-altitude major slide of the jacking platform is achieved in the using process under the conditions such as size deviation of the major structure or off-position of the jacking platform, and the phenomenon that the jacking safety of the jacking platform is seriously affected due to friction generated between box beams of the jacking platform and the major structure is avoided.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a high-altitude integral sliding device for a jacking platform and a construction method. Background technique [0002] With the advancement of science and technology and the improvement of construction technology, there are more and more super high-rise large buildings. Super high-rise construction often uses an integral jacking platform for construction. The jacking platform includes a jacking system, a truss system, a hanger system and a formwork system. In the lifting system, the pressure of the oil cylinder is used to provide the jacking force, and the climbing of the entire jacking platform is realized through the alternate lifting of the upper and lower box girders. [0003] The end of the supporting box girder is kept at a certain distance from the structural wall, and the corbels of the box girder extend into the reserved opening of the wall to provide a stress point...

AI Technical Summary

Problems solved by technology

[0004] In the supporting system of supporting box girder + telescopic corbel, the distance between the supporting box girder and the wall is a problem that needs to be paid attention to during the upgrading of the whole system. During the lifting process, such as wall structure deviation and jacking platform offset will cause the box If the distance between the beam and the wall cannot meet the lifting requirements, there may even be friction between the box girder and the wall, causing potential safety hazards
