Description
Technical Field
The invention mainly relates to the field of dampers, in particular to an assembled beam-column joint fan-shaped damper which can play a good energy-consumption and vibration-reduction role in building structures.
Background
The viscoelastic material is a high molecular polymer, is an energy-consuming material with excellent performance, and has viscosity and elasticity. When the deformation occurs under the action of alternating stress, a part of energy is stored in the form of potential energy, and the other part of energy is converted into heat energy to be dissipated. The viscoelastic damper based on the viscoelastic material is a novel energy dissipation damper used in the wind and vibration (shock) resisting engineering of the structure, and the damper mainly comprises the viscoelastic material and a constraint steel plate, and has the characteristics of economy, practicality, reliable performance, convenience in installation and good damping effect. The existing viscoelastic damper is usually manufactured by adopting a high-temperature high-pressure integral vulcanization mode, so different molds are required to be manufactured for dampers with different specifications, and the cost is higher. Secondly, when a part of the damper is damaged and a steel plate or a viscoelastic material is replaced, the damper needs to be integrally vulcanized again at high temperature and high pressure, so that serious resource waste is caused. Finally, when the damper displacement is too large, the boundary where the viscoelastic material and the restrained steel plate are connected, which is integrally vulcanized even at high temperature and high pressure, is torn first, resulting in failure of the device. If the manufacturing method of high-temperature and high-pressure integral vulcanization is abandoned and adhesive connection is adopted, the adhesive strength of the adhesive connection between the viscoelastic material and the constraint steel plate is generally low, and the strength of the adhesive surface cannot meet the detection and use requirements. On the other hand, the shock absorption of the fabricated building structure usually occupies a larger space, so that how to reduce the volume of the shock absorber and simultaneously improve the connection process of the viscoelastic material and the constraint steel plate become problems to be solved urgently.
Disclosure of Invention

And an adhesive is smeared in the reserved hole on the outer steel plate, and the anti-sliding bolt penetrates through the reserved hole and is embedded into the viscoelastic material plate to a certain depth without penetrating through the viscoelastic material plate.
The two outer steel plates are connected with the limiting pull-joint steel plate through bolts.
The I-shaped pull-joint steel plate is arranged at the bonding boundary of the viscoelastic material plate, the middle steel plate and the outer steel plate and is connected with the middle steel plate and the outer steel plate through bolts, and the I-shaped pull-joint steel plate and the viscoelastic material plate are connected together through bolts and adhesion.

Secondly, when the viscoelastic material in the device is damaged, the viscoelastic material can be quickly replaced by bolts and gluing. Finally, because the damper is not limited by a die, a plurality of dampers can be assembled in batch at the same time, and the production efficiency is greatly improved.
2. According to the assembled beam-column node fan-shaped damper, the bolt is adopted for anchoring the constraint steel plate and the viscoelastic material plate, so that pure adhesive shearing force between the original constraint steel plate and the viscoelastic material plate is changed into anti-sliding force and adhesive shearing force generated by bolt anchoring, the connecting strength of a connecting surface is enhanced, and the ultimate deformation and ultimate load of the damper are increased.
3. The fan-shaped damper of the assembled beam-column joint adopts the I-shaped tension-connection steel plate and the L-shaped tension-connection steel plate, increases the adhesive area at the connecting boundary of the steel plate and the viscoelastic material plate, and the tension-connection steel plate and the viscoelastic material plate are connected in a bolt anchoring and adhesive mode, so that the weakest part of the connection of the steel plate and the viscoelastic material plate, namely the strength at the connecting boundary, is further enhanced.
4. The limiting tension-connection steel plate is arranged between the two outer steel plates in the assembled beam-column joint fan-shaped damper, so that the relative distance between the two outer steel plates is prevented from increasing, namely, the viscoelastic material plate and the adhesive are protected from being pulled when being sheared and deformed, and the connecting strength is further increased.
5. The viscoelastic material plate, the inner steel plate and the outer steel plate in the assembled beam-column node fan-shaped damper do not need high-temperature high-pressure integral vulcanization, when the viscoelastic material plate is replaced and recovered, the device is only required to be disassembled and re-assembled, and the assembled beam-column node fan-shaped damper is convenient and quick.
