Embodiment 1

[0028] Embodiment one, combined with the attached Figure 1-4 , a CSIPs-steel composite structure energy dissipation type seismic node, comprising a vertically arranged beam column 1, characterized in that a connecting plate 2 is fixedly connected horizontally on the beam column 1, and the bottom of the connecting plate 2 is connected by bolts A horizontally arranged beam 3, a first action plate 4 is arranged between the beam 3 and the beam column 1 to absorb the energy generated by the vibration of the beam column 1, and the first action plate 4 is made of alumina ceramics by default material, which has high hardness and can resist compression to a large extent, so it can be placed between the beam 3 and the beam column 1 as a connecting piece to play a certain connection role, but the tensile strength of this board is not enough at the same time, and it is prone to brittleness Fracture, when an earthquake occurs, the beam and column 1 will shake. At this time, the first acti...

Embodiment 2

[0029] Embodiment two, on the basis of embodiment one, in conjunction with the attached Figure 1-9A protection device is also fixedly connected to the connection plate 2, the protection device includes a strut 11 fixedly connected to the connection plate 2 in the transverse direction, and a fixed cylinder 12 is vertically fixedly connected to the strut 11, the The fixed cylinder 12 has a built-in fixed rod 13 fixedly connected to the beam 3. The diameter of the inner hole of the fixed cylinder 12 is larger than the diameter of the fixed rod 13. The upper end of the fixed rod 13 is fixedly connected with a fixed column 14. The fixed column The diameter of 14 is greater than the diameter of the inner circular hole of the fixed cylinder 12, satisfying that under the action of other external forces, the crossbeam 3 will be suspended on the strut 11 through the cooperation relationship between the fixed rod 13 and the fixed column 14 and the fixed cylinder 12. The cylinder 12 is s...

Embodiment 3

[0030] Embodiment three, on the basis of embodiment one, in conjunction with the attached Figure 1-11 , the force component device includes a pair of partitions 22 vertically fixedly connected in the groove of the beam 3, there is a gap between the partitions 22 close to the second action plate 5 and the second action plate 5, two Two elastic plates 23 arranged at vertical intervals are fixedly connected horizontally between the partitions 22, and the elastic plates 23 and the side plates 10 are fixedly connected by a transmission rod 24. Preset, the partitions 22 adopt The lower end is fixedly connected to the beam 3 with bolts, and the upper end is not fixed. The elastic plate 23 fixedly connected between the two partitions 22 can convert the force of the side plate 10 on the longitudinal direction of the cross beam 3 into the force of the elastic plate 23 on the partition. The force in the transverse direction of the plate 22, and the transverse force generated by the part...

Abstract

The invention relates to a CSIPs-steel composite structure energy consumption type anti-seismic joint. The joint comprises a beam column and a cross beam fixedly connected through a connecting plate, the cross beam is connected with the connecting plate through a bolt, a first acting plate is arranged between the beam column and the cross beam, and the first acting plate is crushed to absorb energy after being extruded; and one part of energy of the earthquake on the beam column is consumed to improve the anti-seismic capacity of the joint. A third acting plate arranged between the connecting plate and the cross beam and a damping device connected to the beam column, arranged below the cross beam and used for buffering energy consumption are further included, the third acting plate will be broken and separated out in the earthquake, the cross beam and the connecting plate are in flexible connection, longitudinal force borne by the cross beam is converted into transverse force through a force dividing device to protect the bolt, and in addition, a protection device is further provided to protect the cross beam from falling off when it cannot be guaranteed that the bolt cannot be broken. Compared with a traditional welding joint, the joint has better convenience, shock resistance and practicability.

Description

technical field [0001] The invention belongs to the technical field of steel structure nodes, and in particular relates to a CSIPs-steel composite structure energy dissipation type anti-seismic node. Background technique [0002] Steel structure is one of the most widely used building structures at present. It is widely used in high-rise building construction due to its advantages of light weight, high strength, convenient construction and installation, and short construction period. As people have higher and higher requirements for buildings, Since the seismic resistance of steel structures is much higher than that of traditional building structures, most steel structure buildings now use assembly to greatly improve construction efficiency. However, most of the traditional assembly nodes are fixed by welding. The seismic performance is not good, and it is easy to break when an earthquake occurs and cause the building to collapse. Contents of the invention [0003] In vie...
