A corrugated steel web bridge asynchronous hanging basket

Abstract

The present invention solves the defects that the existing corrugated steel web bridge uses a tower crane to hoist the corrugated steel web, which takes a long time for the tower crane and limits the use of the tower crane, and provides an asynchronous hanging basket for the corrugated steel web bridge, including mutually fixed The lower layer of mobile support and the corrugated steel web are hoisted to the upper layer. The lower layer of mobile support includes four legs supported in the groove of the corrugated steel web on the wing opening steel plate, the two lower beams connecting the legs horizontally and the two legs connecting the legs vertically. Parallel longitudinal beams on the lower floor; corrugated steel web hoisting The upper floor includes four columns vertically and fixedly connected to the two lower beams, two upper main beams connected horizontally to the top of the columns, and two longitudinal beam guide rails fixed to the upper main beam; longitudinal beam guide rails The lower part is connected with a transverse moving device which can move along the axial direction of the longitudinal beam guide rail. The transverse moving device comprises a transverse beam slide rail and a lifting device which is arranged on the transverse beam slide rail and can move along the axial direction of the transverse beam slide rail.

Description

technical field [0001] The invention belongs to the field of bridge construction, in particular to an asynchronous hanging basket for a corrugated steel web bridge. Background technique [0002] A bridge refers to a structure built for a road to cross natural or artificial obstacles. According to the force characteristics, there are five basic types of beam bridges, arch bridges, rigid frame bridges, suspension bridges, and composite system bridges (cable-stayed bridges). Most of the structural load of concrete girder bridges is used to resist the self-weight of the bridge, while the live load of the second phase is only a small part, so reducing the self-weight of the bridge will help increase the span of the bridge and reduce the construction cost. [0003] The corrugated steel web bridge is a new type of steel-concrete composite structure bridge. The top and bottom plates of the box girder are generally made of concrete, while the web is a corrugated steel web. There is ...

Problems solved by technology

[0005] The invention solves the defects that the existing corrugated steel web bridge adopts the tower crane to hoist the corrugated steel web, which takes a long time for the tower crane and limits the use of the tower crane, and provides an asynchronous hanging basket for the corrugated steel web bridge, through which the Complete the movement, installation and hanging of the corrugated steel web on the bridge, shortening the occupation time of the tower crane

[0006] The present invention solves the defect that the existing corrugated steel web bridge uses a tower crane to hoist the corrugated steel web, which can only be carried out in a manner of one hoisting and one installation, resulting in low installation efficiency of the corrugated steel web, and provides a corrugated steel web The bridge asynchronous hanging basket, the corrugated steel web is hoisted to the bridge deck by the tower crane, and the asynchronous hanging basket is docked to complete the movement and installation of the corrugated steel web on the bridge. The sequence is optimized from sequential flow construction to symmetrical parallel construction, which improves the construction efficiency

[0007] The invention solves the problem that the existing corrugated steel web bridge adopts a tower crane to hoist the corrugated steel web. The length of the boom of the tower crane needs to be longer, which is limited by the terrain of the bridge, and at the same time causes high rental costs. It provides a bridge bridge. A corrugated steel web bridge asynchronous hanging basket, the asynchronous hanging basket completes the movement and installation of the corrugated steel web on the bridge. The length of the boom is less affected by the terrain, which can also reduce the demand for tower crane hoisting energy, thereby reducing the rental cost of tower cranes
