Description

An assembled square steel pipe column channel steel connection beam-column joint

technical field

The utility model relates to a beam column connection node in a building structure, in particular to an assembled square steel pipe column channel steel connection node.

Background technique

Beams and columns are part of the building structure and play an important role, so beams and columns have also become the core part of the project. The traditional beam and column construction adopts the method of on-site welding, and the upper and lower flanges and webs of the beam are welded to the column on site. This welding method forms a whole beam and column. Although it is a rigid connection, it leads to poor ductility. After welding, the residual stress is relatively large, brittle fracture is prone to occur, and the on-site welding workload is large, and the construction quality is difficult to control, which will greatly reduce construction efficiency and increase more labor and material costs. At the same time, it will also affect the environment. create pollution.

Contents of the invention

In order to overcome the shortcomings of the above-mentioned prior art, the purpose of this utility model is to provide an assembled square steel pipe column channel steel connection node, which has the advantages of simple and convenient installation, improved ductility, greatly reduced brittle failure, and improved construction efficiency. At the same time, its strength and rigidity are guaranteed.

In order to achieve the above object, the technical scheme that the present invention takes is:

An assembled square steel pipe column channel steel connection node, including a square steel pipe column 1 and an I-shaped steel 3, Y-shaped corner connectors 4 are respectively welded to the four water chestnuts of the square steel pipe column 1; the ends of the I-shaped steel 3 are welded There is an outer channel steel connecting piece 2, and the outer channel steel connecting piece 2 and the Y-shaped corner connecting piece 4 are connected by bolts.

Further, the Y-shaped corner connector 4 includes a right-angle channel steel 41, the water chestnut of the square steel pipe column 1 is welded inside the right-angle channel steel 41, and the right-angle end of the right-angle channel steel 41 is welded with a steel plate 42 with bolt holes.

Further, the outer channel steel connector 2 includes upper and lower concave channel steel 21 with bolt holes on both sides, the webs of the upper and lower concave channel steel 21 are welded by connecting plates 22, and the upper and lower concave channel steel 21 The web of the web is welded with the flange plate of the I-shaped steel 3, and the connecting plate 22 is welded with the web of the I-shaped steel 3.

The beneficial effects of the utility model:

There is no internal partition in the node area of the utility model, and the columns are long, so there is no need to cut off during processing, and the concrete can be poured freely and the quality can be guaranteed, which can effectively improve the rigidity and bearing capacity of the columns;

Components are prefabricated in the factory, which avoids welding operations on the construction site, reduces quality accidents caused by welding defects and fires caused by welding sparks, and at the same time, there is no overhead welding and side welding at the connection site of this node, which is convenient for construction;

The structure is simple, the processing technology is easy, the force mechanism is relatively clear, it is convenient for industrialized manufacturing and on-site assembly, greatly improves the construction efficiency, and can be used for mass production.
