Rectangular square pyramid space grid and shaped steel stand column combined structure

Abstract

The invention relates to a rectangular square pyramid space grid and shaped steel stand column combined structure, and belongs to the technical field of large-span buildings. The combined structure comprises a circular-arch-shaped grid structure, and one end of the grid structure is supported by H-shaped steel stand columns; the grid structure is a rectangular square pyramid space grid and comprises upper chord members and lower chord members, the upper chord members and the lower chord members are spliced into the grid structure, and nodes of the upper chord members and the lower chord members are connected through web members; and outer end intersection points of upper chord member units close to the end supported by the H-shaped steel stand columns are welded to the upper ends of the side wing edges of the H-shaped steel stand columns through upper hollow hemispheres, lower hollow hemispheres are correspondingly arranged below the upper hollow hemispheres and welded to the H-shaped steel stand columns, one upper chord member unit corresponds to two lower hollow hemispheres, and the two lower hollow hemispheres are respectively connected with nodes of a lower chord member grid structure corresponding to the corresponding upper chord member unit through web members. The problem that a boundary support at one end of an existing rectangular square pyramid space grid is limited by space and the end cannot be supported by a fixed hinged support is solved.

Description

technical field [0001] The invention belongs to the technical field of large-span buildings, and in particular relates to a combined structure of an upright quadrangular pyramid grid frame and a shaped steel column. Background technique [0002] Large-span building structures include grid structure, reticulated shell structure, suspension cable structure, truss structure, membrane structure, thin shell structure and other basic spatial structures and various combined spatial structures. [0003] The upside-down quadrangular pyramid system grid frame is the component unit of the quadrangular pyramid system grid rack. The centroid of the upper chord grid is the intersection point of the lower chord grid. The four intersection points from the upper chord grid to the lower chord intersection are connected by diagonal rods, that is, an inverted square pyramid unit is formed. The connection mode of each independent upright quadrangular pyramid can be that the bases of the uprigh...
