Manufacturing method of large-section small-radius hyperbolic box beam

Abstract

The invention relates to a manufacturing method of a large-section small-radius hyperbolic box beam. The manufacturing method is characterized in that the large-section small-radius hyperbolic box beam is designed and disassembled into four blocks of a long flange slab, a short flange slab, a long web plate and a short web plate correspondingly, the long flange slab, the short flange slab, the long web plate and the short web plate are prepared by blanking and bending correspondingly, and then the long flange slab, the short flange slab, the long web plate and the short web plate are assembledand welded to form the large-section small-radius hyperbolic box beam. The manufacturing method has the beneficial effects that by adopting the scheme for manufacturing the large-section small-radiushyperbolic box beam, the error is reduced and the radian of the hyperbola is guaranteed, the appearance of the whole component is ensured, and the processing progress of the component is improved toa greater extent; and the radian of the box beam is guaranteed to be formed at one time, and the phenomenon of folding marks and bumps is further avoided.

Description

technical field [0001] The invention belongs to the technical field of steel structure processing, and in particular relates to a method for manufacturing a hyperbolic box girder with a large cross-section and small radius. Background technique [0002] The development of a city's construction industry also marks its comprehensive strength and social spiritual outlook. People are not only limited to safe and practical buildings, but also require artistic beauty in their shapes. Architects use regular and irregular shapes or shapes to endow buildings with souls. Simple curved structures can no longer meet the needs of architecture, and hyperbolic components are ideal products for architects. In this way, the processing and manufacture of hyperbolic beams has become a very important link in the whole building. There are currently two types of hyperbolic box girders. The first method is to bend the box girder in one direction first, and then raise it to the corresponding si...

Problems solved by technology

The first method is to bend the box girder in one direction first, and then raise it to the corresponding size in the other direction to achieve the hyperbolic effect; this method requires arcs in two directions, so there is no guarantee The overall effect of hyperbolic, the production is not precise; the creases and bulges are obvious, the appearance is not beautiful, and secondary processing is required; multiple bendings are required, the production cycle is long and the efficiency is low; multiple tire frames need to be produced, The process is cumbersome and occupies a large area

The second method is to partially pull out the box girder, and then butt it, and use the straight instead of the curved to achieve the hyperbolic effect; this method has a large amount of welding and low efficiency; the straight instead of the curved, the appearance is not beautiful
