Sliding installation method for large span section steel beam

Abstract

The invention provides a sliding installation method for a large span section steel beam. The sliding installation method comprises the steps that two sliding rails are installed on the two sides of the section steel beam to be installed and positioned respectively; rail ribs are arranged on the sliding rails; base plates arranged on the rail ribs and used for bearing the section steel beam are arranged in the sliding rails; the section steel beam arranged on the base plates is arranged on the two sliding rails in a span mode; turning supports and pulleys arranged on the turning seats are installed at the ends of one sides of the sliding rails; winches used for driving the section steel beam to slide are arranged, and steel wire ropes of the winches penetrate through the pulleys and then are tensioned to the base plates along the sliding rails; according to the installing and positioning points of the section steel beam, the section steel beam is slide in place through the winches. By means of the design of the turning supports and the pulleys, the steel wire ropes of the winches can be turned, the transverse and longitudinal space is fully used, and the difficulty that construction cannot be carried out due to the insufficient longitudinal sliding length of a roof is overcome.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a sliding installation method for large-span steel beams. Background technique [0002] At present, my country's theaters, cultural centers, and stadiums and other buildings all adopt long-span space structures with different shapes. In order to achieve sufficient weight for the floor structure, the required horizontal main girders need to use large-section steel girders to improve their overall performance. The spanning ability and carrying level. The traditional sliding method mostly adopts cluster jacks to be applied to both ends of the beam body, and multi-point synchronous pushing and sliding has defects such as difficulty, large amount of synchronization control input, short single-step sliding stroke, and low efficiency. Construction needs to be carried out in a larger site, and there is a higher requirement for the width of the site. Contents of the invent...
