Problems solved by technology

The anti-seismic ability of houses in rural areas in my country is generally poor, and they collapse seriously in earthquakes. At present, the common seismic isolation device is a laminated steel plate rubber bearing. It is heavy and expensive, and it is mainly designed for high-rise heavy-duty building structures. Most of the houses in villages and towns are middle and low-rise buildings. If laminated steel plate rubber bearings are used for seismic isolation of village and town houses, it will inevitably be a waste. It is urgent to develop a seismic isolation device for middle and low-rise buildings.

Embodiment

[0018] Such as figure 1 and figure 2 As shown, a fiber-polytetrafluoroethylene plate rubber composite shock-absorbing support, the support consists of three parts: rubber layer 2, polytetrafluoroethylene plate 3 and fiber layer 4. The stacking sequence is as follows: rubber layer 2, polytetrafluoroethylene plate 3, rubber layer 2, fiber layer 4, rubber layer 2, stacking several layers in this order and finally ending with the rubber layer to form a laminated body, and then in the laminated body The upper and lower end surfaces of the composite body are respectively added with end steel plates 1, and a rubber protective layer 5 is added around the side of the composite body, and finally vulcanized and bonded.

[0019] In this embodiment, 35 layers of seismic isolation bearings are stacked together, including 17 layers of reinforcement layers, including 9 layers of polytetrafluoroethylene board layers and 8 layers of fiber layers. While reducing the self-weight, the energy d...

Abstract

The invention relates to a fiber and polytetrafluoroethylene plate rubber combined shock insulation support, and belongs to the field of shock insulation for room buildings. The support mainly comprises rubber layers, fiber layers and polytetrafluoroethylene plates which are staggered and laminated according to a sequence of a first rubber layer, one of the polytetrafluoroethylene plates, a second rubber layer, one of the fiber layers and a third rubber layer; a plurality of layers are laminated, and the rubber layer is arranged on the top, so that a laminated body is formed; end steel plates are respectively arranged on the upper end face and the lower end face of the laminated body, and a rubber protection layer is arranged around the lateral direction of the laminated body; and the final support is formed by vulcanization and bonding. The support is light in weight and low in assembly cost; and the vertical rigidity and the bearing capacity of the support can be changed by adjusting the number of polytetrafluoroethylene plates in the support.

Description

technical field [0001] The invention relates to a fiber-polytetrafluoroethylene plate rubber composite shock-isolation bearing, which belongs to the field of house construction shock-isolation. Background technique [0002] Seismic isolation technology can effectively improve the seismic capacity of the building. It usually uses a seismic isolation device installed between the superstructure and the foundation to absorb seismic energy, prolong the vibration period, and reduce the seismic response of the superstructure. The anti-seismic ability of houses in rural areas in my country is generally poor, and they collapse seriously in earthquakes. At present, the common seismic isolation device is a laminated steel plate rubber bearing. It is heavy and expensive, and it is mainly designed for high-rise heavy-duty building structures. The houses in villages and towns are mostly middle and low-rise buildings. If laminated steel plate rubber bearings are used for vibration isolation...
