Prefabricated assembly type large-span steel column connecting structure and construction method thereof

Abstract

The invention discloses a prefabricated assembly type large-span steel column connecting structure and a construction method thereof. The prefabricated assembly type large-span steel column connecting structure comprises a supporting cross beam, a light strip-shaped foundation and a plurality of steel column assemblies. The tops and the bottoms of the steel column assemblies are fixedly connected with the supporting cross beams and the light strip-shaped foundations correspondingly. Each steel column assembly is provided with a diagonal bracing steel pipe assembly and a stay cable assembly, the diagonal bracing steel pipe assemblies are arranged in an inverted triangle structure, the stay cable assemblies are arranged in a regular triangle structure, and the steel column assemblies, the diagonal bracing steel pipe assemblies and the stay cable assemblies are matched with one another, so that the spatial span and the application range of the structure are improved; the structure can be completely assembled, on-site wet operation is avoided, the construction process is conveniently managed in a standardized and informationized mode, the light strip-shaped foundation is combined, the stress of the light strip-shaped foundation is met, meanwhile, the dead weight of the whole structure is reduced, the recycling rate of components and parts after a building (structure) is dismantled is increased, and environment protection is achieved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a prefabricated assembled large-span steel column connection structure and a construction method thereof. Background technique [0002] From the design of the building structure to the actual construction, it is all based on the premise of on-site operation, but the shortcomings of the cast-in-place structure are also obvious, such as high labor intensity, low production efficiency, long construction period, large environmental pollution, slow construction speed, and materials Disadvantages such as excessive loss. Prefabricated buildings have become a brand-new development direction in the construction industry. The standardized and informatized industrialized construction model has become a new orientation. The construction of a building system based on factory prefabrication and on-site mechanized assembly has made up for the traditional construction industry. Th...
