Description

a shock absorber

technical field

The utility model belongs to components used in the field of construction engineering, and particularly designs a novel shock-isolation support with high anti-seismic performance.

Background technique

Earthquakes are composed of horizontal earthquakes and vertical earthquakes. According to current research, the energy of horizontal earthquakes is much greater than that of vertical earthquakes. The damage to many buildings is not necessarily caused by horizontal earthquakes, and On the contrary, damage to buildings is mainly caused by vertical earthquakes.

To resist vertical earthquakes, it is first necessary to solve how to prevent ground vibration from being transmitted to the house, and to ensure that the ground supports the house.

Utility model content

The utility model aims to provide a vibration-isolation support with high anti-seismic efficiency and good support structure, which can enhance the horizontal and vertical balanced anti-pull ability.

The technical solution provided to achieve the above purpose is: a shock-isolation support is provided, which includes a horizontal base, a first platform is provided on the base, a second platform is provided on the first platform, the first platform, The second platform and the base form a ladder-like structure. A bottom steel plate is fixed on the second platform, a top steel plate is arranged above the bottom steel plate, and a plurality of horizontal rubber plates are arranged vertically between the top steel plate and the bottom steel plate. , the bottom steel plate and the top steel plate are connected by multiple vertically extending prestressed steel wires, and multiple vertically extended prestressed steel wires pass through each rubber plate from top to bottom to connect the rubber plates in series, and the horizontal rubber plate and the prestressed steel A plurality of square accommodation chambers are isolated between the stress steel wires, and each accommodation chamber is filled with soft foam boards.

Further, a vertically extending energy-absorbing steel plate is respectively provided on both sides of the bottom steel plate on the second platform, and the energy-absorbing steel plate is at the same height as the top steel plate.

Further, each energy-absorbing steel plate is connected with the upper steel plate through a mild steel.

Further, both the top steel plate and the bottom steel plate are square steel plates.

Further, the base is a hard phenolic foam board.

Compared with the prior art, the utility model has the following beneficial effects:

Multiple soft foam boards are arranged in the interlayer to absorb vertical energy during vibration.

By setting the base of phenolic material to ensure that the ground can be separated from the supporting platform, the vibration energy can be greatly absorbed and the damage of the superstructure can be reduced.

detailed description

Below in conjunction with accompanying drawing, the utility model is described in further detail:

As shown in Figure 1, a kind of shock-isolation bearing is provided, and it comprises horizontal base, is provided with first platform on base, is provided with second platform on first platform, first platform, second platform and base It forms a stepped structure, with a bottom steel plate fixed on the second platform, a top steel plate above the bottom steel plate, a plurality of horizontal rubber plates in the vertical direction between the top steel plate and the bottom steel plate, the bottom steel plate and the top The steel plate is connected with multiple vertically extending prestressed steel wires, and the multiple vertically extended prestressed steel wires pass through each rubber plate from top to bottom to connect the rubber plates in series, and the horizontal rubber plate is isolated from the prestressed steel wire There are a plurality of square accommodation chambers, each of which is filled with soft foam boards. On the second platform, a vertically extending energy-absorbing steel plate is respectively provided on both sides of the bottom steel plate. The energy-absorbing steel plate is equal in height to the top steel plate. Each energy-absorbing steel plate is connected with the upper steel plate through a mild steel.

Both the top steel plate and the bottom steel plate are square steel plates.

The prestressed steel wires are arranged in multiple rows, each row is in a straight line, and most of the prestressed steel wires are distributed in a square shape.

The base is a hard phenolic foam board.

The mechanism of use of the utility model will be further described according to the accompanying drawings:

In the event of an earthquake, the base is made of hard phenolic foam boards that can isolate the vibration of the bottom surface, and the soft steel between the energy-absorbing steel plate and the top steel plate can effectively absorb horizontal vibrations, and the soft foam board between the horizontal foam boards can effectively absorb Vibrate vertically.
