A bolted connection structure between square and rectangular steel pipe column and h-shaped steel beam

Abstract

The invention provides a rectangular steel pipe column-H-shaped steel beam bolted connecting structure. The rectangular steel pipe column-H-shaped steel beam bolted connecting structure comprises a rectangular steel pipe column module, a pitch point module and an H-shaped steel beam. The rectangular steel pipe column module comprises a rectangular steel pipe column and a bottom plate arranged at one end of the rectangular steel pipe column, wherein the area of the bottom plate is greater than the basal area of the rectangular steel pipe column, and the outer edge of the periphery, exceeding the basal area of the rectangular steel pipe column, of the bottom plate is used for being connected with the pitch point module and the H-shaped steel beam. The pitch point module comprises a pitch point, a single shear plate, an upper end plate and a lower end plate, wherein the single shear plate is arranged in a pitch point area, the upper end plate is arranged at the upper end of the pitch point, the lower end plate is arranged at the lower end of the pitch point, the distance between the upper end plate and the lower end plate is greater than the distance between an upper flange and a lower flange of the H-shaped steel beam, the single shear plate is connected with a web of the H-shaped steel beam in a staggered and attached mode, the H-shaped steel beam is embedded in the pitch point module according to the arrangement, bolt holes are formed in the single shear plate and the web of the H-shaped steel beam correspondingly, and bolt holes are formed in the bottom plate, the upper end plate, the lower end plate and the upper flange and the lower flange of the H-shaped steel beam correspondingly. At the time of on-site installation, the modules are directly connected through high-strength bolts, therefore, welding quality is guaranteed, and efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of engineering and relates to a steel pipe column-H-shaped steel beam connection structure in a steel frame structure. Background technique [0002] At present, many countries, such as the United States, Japan, and the United Kingdom, are actively promoting prefabricated steel structure low-rise residences, which are called industrial steel structure residences in Japan. Steel structure housing is widely used in Europe, America, Japan and other countries and regions, and my country's steel structure housing industry has also entered a new stage of development. The national industry standard "Technical Regulations for Light Steel Structure Residences" (JGJ209-2010) has just been implemented, and the Shanghai local standard "Technical Regulations for Light Steel Structures" (DG / TJ08-2089-2012) has also been promulgated and implemented. Compared with traditional brick-concrete structures and reinforced concret...

Problems solved by technology

On-site welding efficiency is low, and welding quality is not easy to guarantee

In addition, the splicing of steel pipe columns requires additional splicing nodes

The structural forms of square rectangular steel pipe and H-shaped steel connection mainly include internal diaphragm joints, diaphragm through joints, outer diaphragm joints, outer channel steel stiffened joints, outer rib ring plate joints, etc., which are more or less used On-site welding, installation is inconvenient, and welding quality is not easy to be guaranteed
