Abstract

The invention discloses a hangar steel truss structure lifting system and a modeling analysis method. The hangar steel truss structure lifting system comprises two door head supporting frames and a hall supporting frame. The door head supporting frames are located on the left side and the right side of the hangar door, the distance between the door head supporting frames and the longitudinal sideface of the corresponding side of the hangar ranges from 8 m to 12 m, and the distance between the door head supporting frames and the front side face of the hangar ranges from 4 m to 5 m. A first lifting device is arranged at the top of the door head supporting frame; one group of hall support frames are arranged along the left side line, the rear side line and the right side line of the hangar at intervals; hall supporting frames located on the left side and the right side of the hangar are longitudinally aligned with the two door head supporting frames correspondingly, and the hall supporting frames on the left side and the right side are arranged in a one-to-one correspondence mode; the hall supporting frames arranged along the rear side line of the hangar are arranged in an arc shape.And a second lifting device is arranged at the top of the door head supporting frame. The technical problems that in the lifting process of a hangar steel net rack structure, rod pieces are bent anddeformed, a net rack is prone to overturning, and engineering accidents are caused are solved.

Description

technical field [0001] The invention belongs to the field of building engineering construction, and in particular relates to a hoisting system and a modeling analysis method for a hangar steel grid structure. Background technique [0002] The hangar and annex building in the north area of ​​the first phase of the maintenance and special vehicle maintenance area of ​​a project adopt a steel structure grid roof, which adopts the construction method of ground assembly and one-time overall lifting. Due to the large span of the hangar steel grid and uneven structural stress, during the construction and unloading of the entire steel grid, local components may generate large stress and strain, and the compression bars are overstressed, resulting in insufficient stability. The overstress of the rods generally occurs at the lifting point or adjacent to it. Once the steel structure grid has overstress, the rods will be bent and deformed, and the grid will overturn in the severe case, ...
