Description

A snap-in full-bolt connection of beam-column joints in steel structures

technical field

The utility model relates to a beam-column joint of a steel structure, in particular to a beam-column joint of a snap-in full bolt connection of a steel structure.

Background technique

In the connection of cold-formed square steel pipe columns and H-section beams, the current method of connecting columns and beams is mainly on-site welding, but the reliability of weld quality is affected by the technical proficiency of the welder and the welding environment. The lack of experience may lead to unreliable welding quality, and the welding environment during welding will also have a certain impact on the quality of the weld. In addition, the on-site welding process is complex and takes a long time, which restricts the whole process. Construction speed of the structure.

At present, the prefabricated construction method has been advocated by the state, and the technical difficulties of prefabricated steel structure buildings are mainly concentrated on the beam-column connection nodes. In steel structure buildings, there are traditionally three connection forms for beam-column connection nodes: (1) the upper and lower flanges are connected by full penetration welds, and the webs are connected by high-strength bolts, that is, a hybrid connection of bolted welding; (2) both flanges and webs are connected. It is a welded seam connection, that is, a full-welded connection; ③ The upper and lower flanges and the web are connected with high-strength bolts, that is, a full-bolt connection. For the first two connection methods, the upper and lower flanges of the beam are fully penetrated connections, which need to be installed and then welded during construction. However, the use of welding methods may lead to quality accidents and fires, and the construction speed will also be greatly affected.

Utility model content

The purpose of the present utility model is to provide a snap-in full-bolt connection steel structure beam-column joint to solve the above-mentioned technical problems.

To achieve the above object, the utility model adopts the following technical solutions:

A snap-in full-bolt-connected steel structure beam-column joint, comprising a square steel pipe column and steel beam components respectively fixed on the surrounding surfaces of the square steel pipe column, each surface around the square steel pipe column is provided with a clamping groove, so the The steel beam assembly includes a beam end plate adapted to the size of the clamping groove and an I-section beam vertically arranged with the beam end plate.

As a further improvement of the above technical solution:

The square steel pipe column is provided with bolts, the beam end plate is provided with mounting holes adapted to the bolts, and the beam end plate is fixedly connected to the square steel pipe column through bolts.

The clamping slot is composed of two L-shaped connecting plates arranged opposite each other and both of which are L-shaped in cross-section, and the two L-shaped connecting plates are respectively vertically fixed on both sides of the side surface of the square steel pipe column.

It also includes a support strip arranged in a horizontal direction, the support strip is fixed on the lower ends of the two L-shaped connecting plates, and the support strip can prevent the beam end plate installed in the card slot from falling off.

It can be seen from the above technical solutions that the snap-in full-bolt connection of steel structure beam-column joints of the present invention has a simple structure and convenient installation, which can effectively improve the construction speed, and greatly improve the safety and reliability. Each H-beam component can be quickly snapped into the slot from top to bottom by hoisting on site, without temporary support and fixation, thus effectively improving the construction speed and greatly improving the safety.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in FIGS. 1-5 , the snap-in full-bolt connection of steel beam-column joints in this embodiment includes square steel pipe columns 2 and steel beam assemblies respectively fixed on the surrounding surfaces of the square steel pipe columns 2 . Each of the surrounding surfaces is provided with a clamping slot 3, and the clamping slot 3 and the side surface of the square steel pipe column 2 together form a U-shaped clamping slot that can be clamped into the clamping plate. The steel beam assembly includes a beam end plate 4 adapted to the size of the clamping slot 3 and an I-shaped section beam 1 arranged perpendicular to the beam end plate 4 .

Bolts 5 are provided on the square steel pipe column 2 , and mounting holes 41 matching the bolts 5 are provided on the beam end plate 4 .

The clamping slot 3 in this embodiment is composed of two L-shaped connecting plates arranged opposite each other and both L-shaped connecting plates are vertically fixed on both sides of the side surface of the square steel pipe column 2 . The lower ends of the two L-shaped connecting plates also include horizontally arranged support bars 6, the support bars 6 are fixed on the lower ends of the two L-shaped connecting plates, and the beam ends installed in the card slots 3 can be blocked by the support bars 6 Plate 4 falls off.

During installation, firstly weld the L-shaped slot 3 and the lower beam support bar 6 to the cold-formed thin-walled square steel pipe column 2, and weld the beam end plate 4 to the beam end of the zigzag section beam 1 to form an H-shaped steel beam assembly. Then, the H-beam assembly is clamped into the groove of the cold-formed thin-walled square steel pipe column from top to bottom by on-site hoisting.
