Description
Technical Field
The utility model relates to an elastic single-slip seismic isolation support for a building.
Background
At present, the building shock insulation elastic sliding plate support applied to engineering practice in China belongs to an unconstrained elastic sliding support, the vertical bearing capacity of the support is large, the friction force of a friction pair formed by a stainless steel plate and a polytetrafluoroethylene plate plays a damping role when an earthquake occurs, the earthquake energy is consumed, and the shock insulation effect is realized. However, the adopted unconstrained elastic sliding support has no limit structure for the bearing elastic sliding main body, so that the shock insulation support has large yielding sliding displacement and small initial rigidity, has low wind load resistance when no earthquake occurs, and cannot be matched with a natural rubber support to form a building shock insulation system independently.
Disclosure of Invention
The utility model aims to provide an elastic single-slip shock isolation support which has small slip yield displacement and large initial rigidity, can be matched with a natural rubber support to form a building shock isolation system, and has strong wind load resistance when no earthquake occurs.
The utility model also aims to provide the elastic single-slip seismic isolation support which does not need a separate sealing element, is reliable in sealing and easy to control the vertical rigidity.
The utility model is realized by the following steps:
the elastic single-sliding shock insulation support comprises an upper seat plate 1, a lower seat plate 5 and a support bearing main body 2 positioned between the upper seat plate and the lower seat plate, wherein the upper seat plate 1 is basin-shaped, a groove 1-3 formed by annular walls 1-2 is formed below the upper seat plate, the support bearing main body 2 is positioned in the groove 1-3, a middle pressing plate 3 is arranged below the support bearing main body, a low-friction-coefficient wear-resisting plate 4 is arranged in a 1 st caulking groove 3-1 below the middle pressing plate 3, the lower part of the low-friction-coefficient wear-resisting plate 4 is higher than the annular walls 1-2, a stainless steel plate 6 is welded on the lower seat plate 5 relative to the low-friction-coefficient wear-resisting plate 4, and the peripheries of the upper seat plate 1 and the lower seat plate 5 are respectively provided with a connecting hole to be connected with an upper buttress and a lower buttress.
The horizontal section of the support bearing body 2 is round, rectangular or square, and at least two layers of thin steel plates are embedded in the support bearing body. The two thin steel plates 2-2 divide the bearing body of the support into at least three laminated rubber layers 2-1.
The utility model has the following advantages:
because the bearing main body of the support is formed by alternately superposing and vulcanizing a plurality of rubber layers and at least two layers of thin steel plates, the structural bearing main body of the support has mature vertical rigidity design and calculation theory and easy control of vertical rigidity.
The bearing main body and the middle pressure plate of the support are restrained by the annular wall of the upper seat plate, so that the support has small sliding yield displacement, large initial rigidity and strong wind load resistance in the absence of earthquakes, and can be matched with a natural rubber support to form a building shock insulation system.
