Abstract

The invention discloses a grid damping support which comprises a grid damper, an elastic supporting body, a top plate and a bottom plate. The grid damper is a shell with the two ends open and the interior hollow, and the shell is made of steel. A plurality of weakening holes are formed in the shell; the elastic supporting body is embedded in a shell of the grating damper. A lower port of the shellis formed in the bottom plate and fixedly connected with the bottom plate, and the lower end face of the elastic supporting body makes contact with the upper surface of the bottom plate; an upper port of the shell is fixedly connected with the top plate, and the upper end face of the elastic supporting body makes contact with a lower panel of the top plate. The grid damping support has the beneficial effects that the steel grating damper is manufactured by forming a certain number of weakening holes with certain shapes in low-yield steel through the high ductility and weakening holes of the low-yield steel, and the novel shock absorption and isolation support is manufactured by combining the damper with the elastic supporting body; the support is high in energy dissipation capacity and has the damping effect in the horizontal direction and the bidirectional direction.

Description

technical field

[0001] The invention relates to the field of bridge engineering and construction engineering shock absorption, in particular to a grid damping support. Background technique

[0002] Buildings and bridges, as important public building structures, play an important role in national production and life. In order to protect them from earthquake damage, in actual engineering, the method of adding shock-absorbing and isolating devices is generally used to improve the structure's earthquake resistance. ability.

[0003] At present, shock-absorbing and isolating bearings are often used in bridges and building structures for shock absorption. Traditional shock-absorbing and isolating bearings include lead rubber bearings, friction pendulum bearings, and high-damping rubber bearings. However, lead-core rubber bearings and high-damping rubber bearings have problems such as heavy metal pollution, low horizontal stiffness, and performance degradation during service; fric...
