Background
The steel structure building has the advantages of light weight, good anti-seismic performance, quick construction and suitability for assembly type buildings, and occupies more and more share in the building market. The steel structure is mainly connected by two modes of welding connection and high-strength bolt connection. Compared with welding connection, the high-strength bolt connection has relatively low technical skill requirements for constructors, does not need the requirements of a welding machine, a power supply and the like, does not need special detection of welding seams, and does not wait for short-time construction pause generated by welding seam detection results. The high-strength bolt is simple in construction operation, suitable for assembly type buildings and wide in application in building markets.
The beam-column connecting joint of the steel structure main body mainly comprises an I shape and a box shape, the flanges of I-shaped steel beams on two sides of the joint are required to be communicated through inner partition plates of the joint according to stress requirements of the beam-column connecting joint, however, the inner partition plates of the beam-column connecting joint of the box-shaped column structure are a difficult point for manufacturing components, when a fourth steel plate of the box-shaped column is welded to form the box shape, the fourth side of the inner partition plates is welded with the column steel plate, the welding position is arranged in a cavity of the box-shaped column, no welding station is arranged, only relatively complex melting nozzle electroslag welding can be adopted, the melting nozzle electroslag welding process is complex, the technical content is high, the welding seam is arranged in the box-shaped column, the radiographic inspection is required, the work efficiency is low, the working hours, the materials and the labor consumption are large, and the use of the bolting joint of the steel structure beam column is limited. Although the special high-strength bolt which can be installed on one side exists at present, the high-strength bolt is high in price and has performance which is inferior to that of a common high-strength bolt, and cannot be popularized and applied.
Patent CN216428564U discloses a steel structure node connection structure comprising beam-column connection members, open square columns and Kong Gongzi steel; the opening square column comprises an upper opening square column and a lower opening square column; the beam column connecting member comprises an outer sleeve and a cross plate, wherein the outer sleeve is sleeved into the square column with the upper and lower openings, and the cross plate is inserted into the square column with the upper and lower openings to connect the square columns with the upper and lower openings. However, when the structure is used for manufacturing the beam column connecting member, the inner partition plate needs to be welded, and the problem that the welding in the box-type steel column is difficult still exists.
Therefore, the technology for installing the common high-strength bolt in the rectangular steel pipe column cavity can thoroughly solve the problem, greatly facilitates the construction of the steel structure main body, improves the construction speed, reduces the engineering cost, and can lead the full bolt joint of the steel structure rectangular steel pipe column and the steel beam to be widely applied.
