Problems solved by technology

Among the existing seismic isolation technologies, laminated rubber seismic isolation bearings are the most widely used, but due to the existence of internal steel plates, the entire bearing is heavy, the construction is inconvenient, and the overall cost is high, so it is not suitable for seismic isolation of rural houses

Embodiment

[0019] Such as figure 1 and image 3 As shown, a cylindrical fiber-steel plate rubber composite shock-isolation bearing is composed of a fiber cloth layer 3, a rubber layer 2 and a steel plate layer 5, and the three are stacked alternately, and the stacking sequence is as follows: rubber layer 2, The fiber cloth layer 3, the rubber layer 2, the steel plate layer 5, and the rubber layer 2 are superimposed in this way to form a composite body, and an end steel plate 1 is added to the upper and lower end faces of the composite body, and a rubber protective layer 4 is added around the side of the composite body, and finally Bonded by vulcanization.

[0020] The diameter D of the vibration isolation support in this embodiment is 320mm, the height is 110mm, and there are 35 layers laminated together, of which the thickness of the rubber layer is 3.1mm, the thickness of the steel plate layer and the fiber cloth layer are both 2mm, the thickness of the end steel plate is 10mm, and t...

Abstract

The invention relates to a fiber-steel plate rubber combined seismic-insulation support which belongs to the field of seismic insulation of housing construction. The seismic-insulation support comprises a fiber fabric layer, rubber layers and a steel plate layer which are overlapped to form an overlapped body in a staggered manner and in the overlapping sequence of one rubber layer, the fiber fabric layer, one rubber layer, the steel plate layer and one rubber layer. End steel plates additionally arranged on the upper end face and the lower end face of the overlapped body and rubber protective layers arranged on sides of the overlapped body are finally adhered by vulcanizing. The fiber-steel plate-rubber combined seismic-insulation support is light in dead weight and has better damping characteristics on the aspects of seismic-insulation and energy dissipation, and construction and mounting cost can be saved.

Description

technical field [0001] The invention relates to a fiber-steel plate rubber composite shock-isolation bearing, which belongs to the field of house construction shock-isolation. Background technique [0002] Seismic isolation technology emerged in the 1960s. It absorbs most of the seismic energy through the large deformation of the seismic isolation support set on the seismic isolation layer, prolonging the structural period, thereby greatly reducing the seismic response of the upper structure. Seismic isolation technology can effectively improve the seismic safety and reliability of buildings. [0003] At present, the houses in villages and towns in our country basically do not have the ability to resist earthquakes. However, individual houses that use seismic isolation technology show good earthquake resistance in earthquakes, which prompts us to think of applying seismic isolation technology to the earthquake resistance of houses in villages and towns. Among the existing s...
