Description

a building steel structure

technical field

The utility model relates to the technical field of building steel structures, in particular to a building steel structure.

Background technique

The high strength of steel makes steel structural columns widely used in the construction industry, especially those often used in long-span or super high buildings. Existing steel structure columns are mainly used for beams and columns on buildings, and most of them adopt the "I" structure, that is, two horizontal flat plates are the upper and lower main ribs, and the middle vertical vertical plate is a supporting web.

At present, when installing a conventional steel structure, the column is generally fixed first, and then the beam is fixed on the side of the column. There are also many ways to fix the beam, such as fixing with bolts or welding, but most of them directly connect the beam to the column. Fix it, but only the force on the connection between the beam and the column will cause the force on the beam to be too concentrated, and the connection may crack or loosen, resulting in insufficient stress strength.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

Please refer to Figures 1-3, the utility model provides a technical solution: a building steel structure, including a column 1 and a beam 2, the column 1 is specifically a square tubular structure, the beam 2 is specifically an I-shaped steel structure, and the surface of the column 1 is from The first fixed sleeve 3 and the second fixed sleeve 4 are respectively sleeved from top to bottom. The first fixed sleeve 3 and the second fixed sleeve 4 are welded and fixed on the surface of the column 1. The first fixed sleeve 3 and the second fixed sleeve 4 are Set it on the surface of the column 1 first, and then weld around it, so as to ensure that it is evenly stressed and increase the strength of the force. The side wall of the first fixed sleeve 3 is provided with multiple insertion slots, and the beam 2 is inserted into the insertion slots. , and the beam 2 and the socket groove are strengthened and fixed by welding, the socket groove can extend the force arm of the beam 2, thereby reducing the shear force at the connection between the beam 2 and the column 1, and the surface of the beam 2 is also installed with Diagonal strut 5 , the other end of which is connected to the side wall of the second fixed sleeve 4 .

Both ends of the diagonal strut 5 are connected with a hinge seat through a pin shaft, and the hinge seat, the beam 2 and the second fixed sleeve 4 are all fixed by welding, and two limit plates 6 are welded and fixed in a plurality of insertion slots. There is a gap between the two limiting plates 6, and the limiting plate 6 can just fit the two sides of the I-shaped beam 2, so as to limit the position of the beam 2 and prevent the beam 2 from swinging greatly In the case where the limiting plate 6 is used in conjunction with the beam 2, the side wall of the first fixing sleeve 3 is also provided with a threaded hole, and a fastening bolt is threaded in the threaded hole, and the fastening bolt can connect the limiting plate 6 to the beam. 2 for fixing, which plays the role of auxiliary fixing, and the fastening bolts pass through the two limiting plates 6 and are fixed inside the first fixing sleeve 3 .

The middle part of the diagonal strut 5 is also hinged with an auxiliary rod 7, and the other end of the auxiliary rod 7 is welded and fixed to the surface of the column 1. The auxiliary rod 7 can play a role in dispersing the force of the diagonal strut 5, thereby improving the force of the diagonal strut 5. Stress strength.
