Description

Beam-to-column connection device for partition through-type steel frame

technical field

The invention belongs to the technical field of construction engineering, and in particular relates to a beam-column connecting device of a clapboard-penetrated steel frame.

Background technique

The prefabricated steel frame structure building is different from the traditional building construction method. The biggest feature is the rapid construction, which puts forward higher requirements for the connection of nodes.

At present, in the prefabricated steel frame structure building, the square steel pipe column-H-beam connection joint forms mainly include inner diaphragm joints, outer diaphragm joints, diaphragm through joints and end plate connection nodes, among which only end plate connection The joints are prefabricated joints, and the other three types all need to be welded on site, but the end plate connection joints are semi-rigid joints, their stiffness is relatively small, and it is difficult to form a plastic hinge at the beam end. Among the above-mentioned connection joint forms, the diaphragm penetration joint has the advantages of higher rigidity, better ductility, and stronger energy dissipation capacity. However, at present, there are very few diaphragm penetration steel frame connection joint forms that can be assembled. Patent CN107489278A discloses a construction method of a box-type column-H-beam steel frame joint, which first welds the beam connecting member, column connecting plate, upper partition, lower partition and lower column into a whole, and then connects the horizontal beam through the beam. The plate, beam connection riser and high-strength bolts fix the H-shaped beam to the column-beam connection member, and the upper column and the column connection plate are fixedly connected by high-strength bolts. However, there are still some deficiencies in this connection method, for example: (1) In the connection node, the lower column and the lower partition are connected by welding, the upper column and the upper partition are bolted through the column connecting plate, and the structures of the upper and lower columns are different , the standardized production of column components cannot be realized; (2) the upper column and the upper partition are connected by high-strength bolts and column connecting plates. If the length of the upper column is too long, it cannot be screwed, which limits the length of the upper column; (3) The position of the column connection plate connecting the upper column and the upper partition is not consistent with the vertical position of the box-shaped short column between the upper and lower partitions, and there is a problem of discontinuous vertical force transmission.

Therefore, on the premise of realizing the standardization of component production, how to provide a fast installation, zero welding on site, and at the same time ensure safety and reliability of the beam-to-column connection form of the partition through-type steel frame is an urgent problem to be solved.
