Super-large-span solid-web steel box girder structure

Abstract

The invention discloses a super-large-span solid-web steel box girder structure. The super-large-span solid-web steel box girder structure mainly comprises two stand columns, wherein steel corbels are arranged on one sides of the outer surfaces of the two stand columns, supports are arranged on the top faces of the two steel corbels, a box girder body is arranged between the two stand columns and is located on the top faces of the supports, and supporting steel beams are arranged on the two sides of the outer surface of the box girder body. The structure has the advantages that the whole structure is divided into the steel corbels, the supports, the box girder body and the supporting steel beams, the steel corbels at the two ends are connected with the columns, the bottoms of the supports are welded to the steel corbels, the box girder body is welded to the top faces of the supports, and the supporting steel beams are welded to the box girder body; the steel corbels and steel ribs embedded in the columns are welded into a whole; and the supports serve as connecting media of the box girder body and the steel corbels, and bending moment release and energy consumption effects can be achieved due to the fact the hinge structure of a disc type support has the characteristic of rotational deformation to a certain degree.

Description

technical field [0001] The invention relates to the technical field of box girder structures, in particular to an ultra-large-span solid-web steel box girder structure. Background technique [0002] In recent years, there have been more and more super-long-span public construction projects in China, such as airports, exhibition halls, gymnasiums, etc. For such super-long-span structures, traditional schemes generally use steel trusses or net trusses, and truss schemes often have a larger truss section. High, the restriction on the clear height of the indoor space is relatively large; while the grid frame is often limited to roof structures and only used for light curtain wall roofs, if it is used for large-span concrete roofs or large-span floors that bear heavy loads In the area, the grid frame will not be applicable. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a super-large-span solid-web steel box girde...
