Embodiment Construction

[0020] Such as figure 1 As shown, an assembled beam-column joint of steel structure that can dissipate energy in an earthquake includes a column 1, a beam 2, and high-strength bolts 3; the column 1 includes a horizontal sleeve 11, and the beam 2 extends into the horizontal sleeve 11. The sleeve 11 is provided with cross bolt sliding grooves 111; the beam 1 is specifically an I-beam, and the flanges on both sides of the beam 1 are provided with cross bolt sliding grooves 111 corresponding to the cross bolt sliding grooves 111 on the horizontal sleeve 11. Sliding groove: the flanges on both sides of the beam 1 are respectively connected with the two surfaces of the sleeve 11 provided with the cross bolt sliding groove 111 . The high-strength bolts 3 pass through the cross bolt sliding grooves 111 on the flange of the beam 1 to connect and fix the beam 1 and the sleeve 11 .

[0021] A shock absorber 4 is provided at the contact surface between the beam 2 and the vertical column ...

Abstract

The invention discloses a fabricated steel structure beam and column joint capable of consuming energy in an earthquake. The fabricated steel structure beam and column joint comprises a column with asleeve, a steel beam, cross-shaped bolt sliding grooves formed in the connecting face of the sleeve and the steel beam, a high-strength bolt for connecting the steel beam with the column, and rubber damping pads arranged in the sleeve. The column with the sleeve and the beam end are connected together through the high-strength bolt; the rubber damping pads are arranged in the sleeve and located onthe contact surface of the beam end and the column, the beam end impacts the rubber damping pads in the earthquake, and thus damage of impact between components to the structure is reduced; and the column with the sleeve is prefabricated through a factory, the bolt sliding grooves can be formed in the top face, the bottom face, the front face and the rear face of the sleeve according to beam andcolumn connection needs, under the earthquake effects of different directions, the bolt can slide in the different directions of the cross-shaped sliding grooves, and thus the purpose that the joint can consume the energy under the earthquake effects of the different directions is achieved.

Description

technical field [0001] The invention relates to a building structure, in particular to an assembled steel structure beam-column node capable of dissipating energy during an earthquake and a manufacturing method thereof. Background technique [0002] Beam-to-column connections are often made by means of welding, bolting, etc. The welding stiffness is relatively high, but the operation is complicated and the construction quality is difficult to guarantee. Although the bolt connection is less rigid than welding, the bolt connection operation is very convenient and the quality can be guaranteed, so the bolt connection is very suitable for fabricated steel structures. High-strength bolts are widely used due to their advantages such as high strength grade and strong bearing capacity. [0003] In the traditional bolt connection, bolt holes with a diameter close to the diameter of the bolt rod are opened on the connecting part and the connected part. However, opening many bolt hole...
