Truss with adjustable curvature for curved structure, and application method of truss

Abstract

The invention relates to a truss with an adjustable curvature for a curved structure. The truss comprises an upper chord steel plate, a lower chord steel plate, and a plurality of V-shaped round steelweb members, wherein a strip-shaped bolt hole is formed in the lower chord steel plate in the length direction; the V-shaped round steel web members are uniformly arranged between the upper chord steel plate and the lower chord steel plate; a triangular structure is formed by the two edges of each V-shaped round steel web member and the upper chord steel plate; a triangular structure is also formed by the adjacent edges of every two adjacent V-shaped round steel web members and the lower chord steel plate; a fastening bolt is welded at the bottom of each V-shaped round steel web member and fixed on the lower chord steel plate through a fastening nut; and n-shaped spring steel plates are uniformly welded on the lower surface of the upper chord steel plate, and the two ends of each n-shapedspring steel plate are respectively fixedly welded with the corresponding edges of the corresponding V-shaped round steel web members. The truss has the advantages that adjustments can be made according to a line form of the curved structure, so that the applicability for curved structures with different curvatures can be achieved; and the truss is reusable.

Description

technical field [0001] The invention belongs to the field of industrial buildings, structures and building construction, and in particular relates to an adjustable curvature truss with a curved surface structure and a method thereof. Background technique [0002] Curved surface structure is a common structure type in construction, mainly to meet the needs of industrial structures and architectural appearance, and can be divided into horizontal curved surface structure, vertical curved surface structure and spatial curved surface structure. At present, in the field of housing construction, ordinary steel pipes, steel bars and formwork are mostly used for bulk assembly and reinforcement. Generally, the formwork is installed first, then the steel pipe or steel support structure is bent and assembled, and finally the formwork support system is reinforced. The support components of different curved surface structures cannot be shared. After the construction is completed, mainly ...

Problems solved by technology

However, this method has certain limitations. The length of each member of the inner and outer trusses needs to be designed, calculated, and customized. It is a one-time formwork system that cannot be reused and is not economical.
