A double-pipe composite column with energy-dissipating and shock-absorbing functions and its construction method

Abstract

The invention discloses a double-pipe combined column having energy dissipation and shock absorption effects. The column comprises two steel pipe column branches, multiple groups of inter-column beams and column side bracket beams, wherein the inter-column beams are arranged between the column branches and are in welded connection with the column branches; the same groups of column side bracket beams and inter-column beams are located on the same plane; and bolt mounting holes are formed in the column side bracket beams. The double-pipe combined column having the energy dissipation and shock absorption effects has the small section size and can be hidden in a wall body, and column edges are not exposed; simple and convenient joint connection is realized, and the onsite construction speed is high; the column is high in applicability and can be applied to center columns, side columns and corner columns; the column is high in cross-section efficiency and flexible to arrange, the distance between the column branches of the double-pipe combined column is adjustable, and the column can be adapted to change of door and window holes; and the column has multiple advantages that the cross-section is closed, anti-corrosion and fireproof costs are saved and the like, can be applied to structures such as steel structure houses, multi-story and high-rise buildings and the like, and has the better popularization and application prospect.

Description

technical field [0001] The invention relates to the field of building structures, in particular to a double-pipe composite column with energy dissipation and shock absorption functions and a construction method. Background technique [0002] Traditional residential structures in my country are dominated by masonry structures and concrete structures, with extensive construction methods and on-site wet operations. This not only leads to weak technological innovation and integrated innovation capabilities, but also reduces the efficiency of resource and energy utilization. quality and longevity. Steel structure housing has the advantages of high degree of assembly, high processing precision, good seismic performance, green and recyclable materials, and is currently a hot spot in the research of industrialized housing. [0003] Since the unit cost of steel is much higher than that of concrete, the cost of steel structure housing is relatively high, which has become an important ...

Problems solved by technology

However, when it is applied to multi-story residential buildings, due to the large axial pressure and the large cross-sectional size of the columns, it is difficult to completely hide them in the inner and outer walls, and the resulting column edges protruding from the interior will have a great impact on the use of the house. , affecting the promotion and application of steel structure housing

In addition, the beam-column connection usually adopts a bolt-welding hybrid connection method of web bolting and flange welding. Due to the high-altitude welding required on site, the welding quality is often difficult to guarantee due to the influence of on-site operating conditions and environment.
