Description

Technical Field

[0001] The invention relates to the technical field of building engineering structures, and in particular to an assembled beam column with an earthquake-resistant structure. Background Art

[0002] Prefabricated beams and columns are an important structural form in modern construction technology. They prefabricate beam and column components in the factory and then transport them to the construction site for assembly to achieve fast, efficient and high-quality construction, which can significantly shorten the construction period and reduce the generation of construction waste.

[0003] The seismic performance of prefabricated beam-column structures depends to a large extent on the design and construction quality of their connection nodes. In early prefabricated structures, connection nodes often use simple welding or bolting methods. These connection methods are prone to fatigue cracks or loosening under high stress, resulting in a decrease in the overall stiffness and strength of the structure. Especially under the action of earthquakes, connection nodes may become weak links, affecting the seismic performance of the structure. The connection nodes of prefabricated beam-column structures generally use friction plates to improve seismic resistance. With long-term use, the friction plates will produce irreversible wear, resulting in reduced seismic performance between beams and columns. Summary of the invention

DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Embodiment 1: A prefabricated beam column with earthquake-resistant structure, such as Figure 1-Figure 6As shown, it includes: a frame column 1, a frame beam 3 is arranged on the right side of the frame column 1, the frame column 1 is clamped with the frame beam 3 through a corbel 2, a clamping groove is arranged on the frame beam 3, the frame beam 3 uses the clamping groove on it to cooperate with the corbel 2, so as to realize the connection between the frame column 1 and the frame beam 3, and the shear resistance of the frame column 1 and the frame beam 3 is improved by arranging the corbel 2; a prestressed steel bar is connected between the frame column 1 and the frame beam 3, and a buffer gasket is installed between the fixing point of the end of the prestressed steel bar and the frame column 1, and the buffer gasket is set as a rubber pad, which is used to increase the connection strength between the frame column 1 and the frame beam 3, and the corbel 2 An isolation pad 4 is installed between the frame column 1 and the frame beam 3, the corbel 2 is set to N shape, the isolation pad 4 is wrapped around the corbel 2 and contacts with the end of the frame beam 3, and is used to isolate the seismic force between the frame column 1 and the frame beam 3. The isolation pad 4 is integrally formed, and the isolation pad 4 isolates the seismic force both horizontally and vertically. At the same time, the isolation pad 4 also plays a role in friction energy dissipation; two steel plates 5 are provided, and the two steel plates 5 are symmetrically fixed to the front and rear sides of the frame column 1.

The buffer gasket and the seismic isolation pad 4 work together to reduce the hard squeezing force of the frame beam 3 on the front and rear corbels 2. The pull rod passes through the corbel 2 and the seismic isolation pad 4. The pull rod is used to ensure the squeezing force between the friction plate 7 and the frame beam 3, which not only improves the connection strength between the steel plate 5 and the frame beam 3, but also limits the position of the friction plate 7. The frame beam 3 is provided with a slide groove, and the pull rod passes through the slide groove of the frame beam 3 When the frame beam 3 undergoes lateral displacement, the pull rod will produce relative displacement with the slide groove of the frame beam 3; there are two groups of extrusion components, and the extrusion components are arranged between the steel plate 5 and the first extrusion plate 6. The extrusion components squeeze the friction plate 7 through the first extrusion plate 6 to consume energy by squeezing the friction plate 7.

At the same time, when the frame beam 3 is displaced to the right, the friction resistance between the friction plate 7 and the frame beam 3 gradually increases. On the basis of the energy dissipation by squeezing the friction plate 7, variable force friction energy dissipation is achieved, and the connection stability between the frame column 1 and the frame beam 3 is improved.

A fixed seat 13, when the deformation of the frame beam 3 is too large, the shearing blade at the lower end of the shear plate 12 is used to shear the shear nail 18, thereby realizing energy dissipation. When the frame beam 3 recovers, the shear plate 12 is reset synchronously with the damping rod 11. Under the elastic force of the elastic member 17, the shear nail 18 slides forward along the lower mounting portion of the damping rod 11, and the front end of the shear nail 18 is pressed against the first fixed seat 13 again; a friction energy dissipation component is arranged on the corbel 2, and the friction energy dissipation component is used to increase the friction between the seismic isolation pad 4 and the frame beam 3.

During the process of contraction and energy dissipation of the damping rod 11, the telescopic end of the first piston rod 19 is squeezed onto the fixing plate 20, and the telescopic end of the first piston rod 19 contracts; two symmetrical second extrusion plates 21 are provided, and the two second extrusion plates 21 are both slidably connected to the corbel 2, and the seismic isolation pad 4 is located on the outside of the two second extrusion plates 21, and the two second extrusion plates 21 are in contact with the seismic isolation pad 4, and the two second extrusion plates 21 move away from each other, which is used for The two sides of the seismic isolation pad 4 are squeezed to increase the squeezing force between the seismic isolation pad 4 and the frame beam 3.

A one-way valve is installed at the connection between the second piston rod 23 and the oil guide pipe. The telescopic end of the second piston rod 23 is fixedly connected with a wedge block 24. The wedge block 24 and the two squeezing blocks 22 squeeze The second piston rod 23 is press-fitted, and the extended end of the second piston rod 23 extends upward. The wedge block 24 squeezes the two squeezing blocks 22 and makes them move away from each other.
