A new connection node between H-shaped steel column and H-shaped steel beam

technical field

The utility model relates to the technical field of construction engineering, in particular to a connection node between a novel H-shaped steel column and an H-shaped steel beam.

Background technique

With the continuous maturity of steel structure design technology and its excellent performance under complex conditions, steel structure buildings have become more and more popular, especially in multi-storey and high-rise buildings. In the current practical application in our country, the H-shaped steel column of the steel frame is generally connected with the H-shaped steel beam by welding. Although it has a large rigidity and bearing capacity, it has high requirements for the quality of the weld; on-site welding is labor-intensive. The quality of the weld is not easy to be guaranteed, and the joints are prone to brittle failure due to factors such as weld defects. At the same time, due to its low ductility, it may lead to the overall collapse of the structure.

Utility model content

The purpose of this utility model is to overcome the shortcomings of the prior art, to provide a new type of connection node between H steel columns and H-shaped steel beams without weld seam connection and easy to install. The beams and columns are all connected by high-strength bolts, so that Weld defects caused by welding are avoided at the construction site, labor intensity is reduced, construction quality is improved, and mechanical properties of joints are effectively improved.

In order to achieve the above purpose, the technical solution of this utility model is: a new type of connection node between H-shaped steel column and H-shaped steel beam, including H-shaped steel column, H-shaped steel beam, equilateral angle steel, unequal angle steel and friction type high-strength Bolts, the equilateral angle steels are symmetrically arranged on the upper and lower flanges of the H-shaped steel beam; the unequal angle steels are symmetrically arranged on the left and right sides of the web of the H-shaped steel beam; the flanges of the H-shaped steel beam The flange of the H-shaped steel column is connected with the friction type high-strength bolt through the equilateral angle steel; the web of the H-shaped steel beam and the flange of the H-shaped steel column pass through the unequal angle steel Connect with the friction-type high-strength bolts; the H-shaped steel column, H-shaped steel beam, equilateral angle steel and unequal angle steel are all hot-rolled steel; the equilateral angle steel has a total of four, two on each side and uniform It is symmetrically arranged on the upper and lower flanges of the H-shaped steel beam; there are four unequal angle steels in total, two on each side, and they are evenly and symmetrically arranged on the left and right sides of the web of the H-shaped steel beam.

Compared with the prior art, the utility model has the following advantages:

The connection between the H-shaped steel beam and the H-shaped steel column is connected by friction-type high-strength bolts, which realizes on-site assembly, avoids on-site welding, and avoids the adverse effects of welding stress and welding deformation on joint performance; the web of the H-shaped steel beam passes through the friction type The connection between high-strength bolts and unequal angle steel increases the stiffness of the joints and enhances the overall stability of the structure; the installation is simple, the amount of on-site work is small, and the construction efficiency is improved; and the H-shaped steel beams and H-shaped steel columns can be completely prefabricated by the factory. It overcomes the shortcomings of cumbersome procedures on the traditional construction site, high labor intensity, and large errors in on-site construction and installation.
