Assembly type large-span cold-bending solid-web arch structure

Abstract

The invention discloses an assembly type large-span cold-bending solid-web arch structure. The structure comprises rigid arch units, densely-distributed tie bar connecting units and non-densely-distributed tie bar connecting units, wherein the rigid arch units, the densely-distributed tie bar connecting units and the non-densely-distributed tie bar connecting units are all made of steel, the densely-distributed tie bar connecting units and the non-densely-distributed tie bar connecting units connect the rigid arch units into an integral structure through specific connecting joints, and bolt connection is adopted during field installation. The structure is a fabricated structure, no welding exists on a construction site, the construction period is short, and the construction quality is easyto control; the structure is an arch structure, force transmission is clear, the number of used components is small, the structure self-weight is small, the spanning capacity is large, steel is saved, and the space utilization rate is high; and the number of dead angles of components are few, the secondary rust removal and corrosion prevention workload is small, the rust removal quality is easy to control, and the practical significance and the good application prospect are achieved.

Description

technical field [0001] The invention relates to the technical field of building frames, in particular to a prefabricated large-span cold-formed solid abdominal arch structure. Background technique [0002] The existing closed warehouse generally adopts portal rigid frame structure and grid structure. These two structures have the characteristics of simple force bearing, clear force transmission path, and easy factory processing, so they are widely used in industrial and civil buildings. However, the spanning capacity of the portal rigid frame structure is limited, and it is not suitable for the structure with large span; the grid structure usually adopts the welded hollow ball node grid and the bolted ball node grid, and the welded hollow ball node grid has a large amount of on-site welding work. , The welding quality is not easy to control, the required labor cost is large, the construction period is long, the single weight of the bolt ball in the bolt ball joint grid is re...
