Plug-and-play steel structure beam and column connector and method

Abstract

The invention discloses a plug-and-play steel structure beam and column connector, which comprises an I-shaped steel column and an I-shaped steel beam, the flange plates of both sides of the column are respectively provided with two round holes which are symmetrically arranged from the top down and used for the insertion of a short bolt and a long bolt, the end surface of the end of the beam is connected with a connecting plate, the connecting plate is provided with holes which correspond to the round holes formed in the column, wherein the shape of each of the lower row of holes is an inverted U of which the lower end is open, and a section of lower flange, the length of which is greater than the length, extending out of the outer surface of the flange of the column, of the long bolt is also cut off from the end of the beam along the length direction. The connection form of the plug-and-play steel structure beam and column connector is simple, and the plug-and-play steel structure beam and column connector is quick and reliable to install on the site, is plug-and-play, greatly increases the speed of construction, and also decreases workload. The invention also discloses an implementation method of the plug-and-play steel structure beam and column connector.

Description

technical field [0001] The invention belongs to the technical field of building structures, and relates to a beam-column connection device, more specifically, to a plug-and-play steel structure beam-column connection device and method. Background technique [0002] Compared with other structures, steel structure has many advantages, which are highlighted in the recyclable steel and environmental protection; the characteristics of steel structure factory production and on-site installation are conducive to the industrialization of construction. Therefore, steel structure is an inevitable development trend of building structure. [0003] The beam-column system is the most widely used in steel structures. At present, the most widely used beam-column connection method is the bolt-weld hybrid connection, such as figure 1 As shown, the lug plate 7 and the connecting plate 6 are pre-welded in the factory on both sides of the flange of the column 1, and the beam 2 is first hoisted ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned installation process has two main defects: welding construction is required on site, so there are special requirements for electricity and equipment, and at the same time, it affects the peripheral environment and construction progress; the crane is always in working condition during installation, so the installation of beams and columns is easily affected by wind

The above two defects ultimately affected the popularization and application of steel structures to a certain extent.
