Problems solved by technology

[0002] At present, most of the building structures are built with reinforced concrete or welded steel. On-site construction operations are noisy, dusty, water pollution is serious, and construction waste is common, which has a great impact on the surrounding environment; in addition, it takes up a lot of labor resources. , low efficiency, and long construction period directly increase the overall cost; the new type of fabricated steel structure can reduce environmental pollution, save building materials, shorten the construction period, and save labor costs, thereby greatly reducing the cost of the enterprise

Abstract

The invention discloses a fabricated steel-frame structure joint which comprises a joint core. The joint core comprises an upper end plate, a lower end plate, an upper end connector, a lower end connector, a circumferential connector and a core column; the upper end plate is fixedly arranged on the upper end face of the core column, and the lower end plate is fixedly arranged on the lower end faceof the core column; the upper end connector is fixedly arranged on the upper surface of the upper end plate, and the lower end connector is fixedly arranged on the lower surface of the lower end plate; a box column comprises an upper box column and a lower box column, and the box column sleeves the upper end connector and the lower end connector and is connected with the upper end connector and the lower end connector through bolts; one end of the circumferential connector is fixedly connected with the side wall of the core column, and the other end of the circumferential connector is connected with one end of a truss frame beam through bolts. By arranging the joint core, rigid connection between a steel-frame beam structure and a column structure is realized, the structure is simple andreasonable, the force transmission is clear, the fabrication speed is high, and the construction quality is high.

Description

technical field [0001] The invention belongs to the technical field of steel structures, in particular to an assembled steel frame structure node. Background technique [0002] At present, most of the building structures are built with reinforced concrete or welded steel. On-site construction operations are noisy, dusty, water pollution is serious, and construction waste is common, which has a great impact on the surrounding environment; in addition, it takes up a lot of labor resources. , low efficiency, and long construction period directly increase the overall cost; the new fabricated steel structure can reduce environmental pollution, save building materials, shorten the construction period, and save labor costs, thereby greatly reducing the cost of the enterprise. Therefore, it is of great significance to develop prefabricated structures in terms of saving resources, protecting the environment, and reducing enterprise costs. [0003] Compared with the overall design of...
