Problems solved by technology

The above-mentioned traditional viscous damping wall has the following disadvantages: the displacement velocity between layers is limited, which limits the energy dissipation capacity of the damping wall. When loaded, the product bends and deforms, resulting in product failure. Therefore, we propose a velocity-amplified viscous damping wall to solve the above problems

Embodiment Construction

[0020] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] combine figure 1 and image 3 , a velocity amplification type viscous damping wall of the present invention comprises a positioning beam 1 fixed to a building beam, the positioning beam 1 is fixedly connected to the bottom of the upper beam of the building, and the bottom end of the positioning beam 1 is connected with a straight rack through a fixing bolt 2, and the spur rack 2 is flexibly connected to the gear 3 through the gear structure, because when the interlayer displacement is caused by wind load or earthquake, the relative displacement of the lower beam is transmitted to the gear 3 through the positioning beam 1, so that the gear 3 passes through the gear structure Rolling occurs on spur rack 2. The gear 3 is fixed in the box body 5 through the gear pin shaft 4, and several shear plates 6 are arrange...

Abstract

The invention relates to a speed amplification type viscous damping wall. The speed amplification type viscous damping wall comprises a locating beam. A straight rack is fixed to the bottom end of thelocating beam. The straight rack is movably connected with a gear through a gear structure. The gear is fixed to the interior of a box through a gear pin shaft. The box is located below the gear andprovided with a plurality of shear plates. Each shear plate is fixedly connected with the gear. The box is filled with damping fluid. In case of inter-story displacement, the straight rack drives thegear and the shear plates to rotate through the gear structure, and the shear plates shear the damping fluid when moving in the box. If inter-story displacement occurs in the direction perpendicular to the plane, slippage occurs to the straight rack and the gear, the shear plates does not move in the box, and then the damping wall is protected against damage to shear force. If the inter-story displacement occurs at an angle with the plane, the straight rack and the gear decompose motion into motion in plane and motion perpendicular to the plane. Under the condition of not damaging the dampingwall, energy of an earthquake or wind is dissipated to achieve the purpose of protecting a building.

Description

technical field [0001] The invention relates to the field of shock absorption of building engineering structures, in particular to a velocity amplifying viscous damping wall. Background technique [0002] The viscous damping wall is a damper in which the movement of a steel plate in a closed high-viscosity damping fluid causes the damping fluid to shear and deform to generate a viscous damping force. The viscous damping wall is a velocity type damper. As the velocity increases, its damping force increases. It has the technical characteristics of being effective from small displacement to large displacement, good cycle performance, and good reset after earthquake. It can effectively reduce the acceleration response of the upper structure, and it is effective for both wind vibration and earthquake effects, and can meet the wind load comfort and earthquake resistance requirements of high-rise buildings at the same time. This product is not only suitable for the shock absorptio...
