Hydraulic lifting method for steel structure building

Abstract

The invention discloses a hydraulic lifting method for a steel structure building. The hydraulic lifting method comprises the following steps that hydraulic lifting equipment is assembled; a first building module and a plurality of second building modules are assembled, wherein the first building module at least comprises two planes of a roof and a top layer, and the second building modules and the multiple building modules at least comprise one two-floor-layer face lower than the first building module; the first building module is lifted through the hydraulic lifting equipment; the second building modules are lifted to the bottom of the first building module through the hydraulic lifting equipment; the second building modules are fixedly connected to the bottom of the first building module; and the second building modules and the first building module are repeatedly combined and lifted through the hydraulic lifting equipment, and the next second building module is fixedly connected to the bottom of the last second building module till the steel structure building is assembled. In the abovementioned way, the assembling process of the steel structure building is simpler, the safety risk is low, the mounting speed is high, and efficiency is high.

Description

technical field [0001] The invention relates to the technical field of steel structure building assembly, in particular to a hydraulic lifting and hoisting method for steel structure buildings. Background technique [0002] In the prior art, the installation of the prefabricated steel structure construction project adopts the overall lifting technology of the portal tower multi-anchor cluster hydraulic through-hole jack for hoisting. The column and beam nodes are used as lifting points (for example, when the column network is relatively dense, the beam combination lifting point is set), which will greatly reduce the difficulty of installation and construction. It is beneficial to quality, safety and construction period. The overall lifting system of the hydraulic through-hole jack is a new type of construction mechanical device with large output and flexible use. It is composed of three parts: the actuator, the control system and the power device. [0003] Among them, when...
