Background technique

Rectangular steel pipe columns have the advantages of equal strength in all directions, high torsional rigidity, no weak axis during bending, and high bearing capacity, and are widely used in steel frames. At present, the beam-to-column connections of rectangular steel pipe columns and steel frames are mainly rigid connections, but the rigid connections require on-site welding, the construction speed is slow, and the construction quality is not easy to guarantee. In addition, brittle fractures occurred in the Kobe earthquake in Japan in 1995. Steel frame beams and columns are connected by high-strength bolts and connectors (angle steel, T-shaped steel, end plates, etc.), so that the welding work can be completed in the factory, and the construction site only needs to be connected by high-strength bolts. The construction is fast and the quality is easy to guarantee. , The processing and installation of components and nodes are easy to realize industrialization and standardization, which is the development direction of beam-column connection. the

The direct bolt connection between the rectangular steel pipe column and the steel beam, when the node is loaded, the flange plate of the column is prone to out-of-plane deformation, the bearing capacity of the node is small, especially the stiffness of the node is small, the hysteretic curve is pinched, the energy dissipation capacity is low, and the earthquake resistance The performance is poor, and it does not meet the seismic requirements of strong nodes and weak members. the

Contents of the invention

The purpose of the present invention is to address the deficiencies in the prior art, especially the poor seismic performance of the existing rectangular steel pipe column and I-beam bolt connection node, to provide a rectangular steel pipe column I-beam bolt connection structure, the construction site of the present invention No welding is required, and out-of-plane deformation of the column flanges is avoided by reinforcing the rectangular steel pipe columns with jacket steel plates. the

In order to realize the above-mentioned purpose of the invention, the present invention adopts the following technical solutions:

The invention includes a rectangular steel pipe column, an I-shaped steel beam, a jacket steel plate and high-strength bolts. The joints of the rectangular steel pipe columns are covered with steel plates, and the outer steel plates and the rectangular steel pipe columns are connected by peripheral fillet welds or electric rivet welding. The jacket steel plate is a rectangular steel pipe, or formed by welding steel plates. The end of the I-beam beam is welded with an end plate or a T-shaped connector. Drill threaded holes at the positions corresponding to the high-strength bolts, tighten the high-strength bolts to connect the rectangular steel pipe column with the end plate or T-shaped connector of the I-beam, or drill bolt holes at the corresponding positions of the high-strength bolts, and the high-strength bolts will pass through Through the jacket steel plate and rectangular steel pipe column, and connected with the end plate or T-shaped connector of the I-beam. Thereby realizing the beam-column connection of the steel frame. the

The beneficial effects of the present invention are:

(1) All the welding of the connecting nodes of the rectangular steel pipe column and the I-beam of the present invention is completed in the factory, and the construction site only needs to be connected by bolts. Due to the realization of industrialization and standardized production, the construction speed is accelerated and the construction quality is easy to control. the

(2) Compared with the existing rectangular steel pipe column and I-beam bolted joints, the joints have higher stiffness and higher bearing capacity, especially the joints have good seismic performance and strong energy dissipation capacity, which meets the seismic requirements of strong joints and weak members . the
