Description

seismic isolation support for a building

technical field

The utility model relates to a shock-isolation device, in particular to a building shock-isolation support.

Background technique

In the building anti-seismic technology, the traditional technology mainly relies on the deformation of the engineering structure to reduce the damage caused by the earthquake. However, in the case of a large earthquake or an extremely large earthquake, only relying on the structure and its components can play a limited role, and often still cause serious casualties. Therefore, the anti-seismic technology has been developed from many aspects, and the anti-seismic technology is one of the branches. The anti-seismic technology does not require external energy, and has been applied in structures such as buildings and bridges. From the point of view of the currently widely used seismic isolation devices, due to the limitation of their use conditions, they cannot isolate or reduce vertical earthquakes, but can only isolate horizontal earthquakes, and the structure is complex and the cost is relatively high. High, it is difficult to popularize and apply.

Therefore, it is necessary to improve the existing seismic isolation bearing so that it can not only isolate or reduce vertical earthquakes, but also isolate horizontal earthquakes, and has a simple structure and is easy to popularize and apply.

Utility model content

In view of this, the purpose of the utility model is to provide a building isolation bearing, which can not only play the role of isolating or reducing vertical earthquakes, but also can play the role of isolating horizontal earthquakes.

The building shock-isolation support of the utility model includes a mounting seat and a connecting plate used to connect with the building, and also includes a shock-isolation assembly arranged in the mounting seat and used for the connecting plate to bear pressure and isolate the building; The shock assembly includes a rolling layer arranged at the bottom of the mounting seat to reduce the horizontal friction between the shock-isolating assembly and the mounting seat, a bearing plate arranged on the rolling layer, and a bearing plate arranged between the bearing plate and the connecting plate. Between the supporting column and the elastic connecting column.

Further, the supporting columns and the elastic connecting columns are radially arranged, and springs are provided between the supporting columns and the elastic connecting columns and between the elastic connecting columns.

Further, the rolling layer includes rollers arranged in the horizontal direction and a groove for preventing the rollers from splashing.

Further, the support column is a lead column.

Further, hollow pads are provided between the support column and the bearing plate and between the connecting plate and the mounting seat.

Beneficial effects of the utility model: the structure of the building isolation bearing of the utility model is simple, the cost is low, and the construction is convenient. It can not only isolate or reduce vertical earthquakes, but also isolate horizontal earthquakes. The structure is simple and suitable for application and promotion.

detailed description

Fig. 1 is a schematic structural view of the utility model, and Fig. 2 is a top view of the seismic isolation assembly, as shown in the figure: the building seismic isolation support of the utility model includes a mounting base 16 and a connecting plate 13 for connecting with a building , the connecting plate 13 is provided with screw holes 1 and 14 for fixedly connecting with the building, and also includes a shock-isolation assembly arranged in the mounting seat 16 and used for the connection plate to withstand the shock of the building; the shock-isolation assembly includes The rolling layer arranged at the bottom of the mounting seat to reduce the horizontal friction force between the shock-isolation assembly and the mounting seat, the bearing plate 17 arranged on the rolling layer and the bearing plate 17 arranged between the bearing plate and the connecting plate The supporting columns 2, 12 and the elastic connecting columns 5, 7, 9, the elastic supporting columns can be made of a plurality of steel plate layers and a plurality of rubber layers vulcanized together at high temperature and high pressure, or can be made of other elastic materials; The inside of the mounting base 16 is provided with a groove matching the bearing plate 17 to ensure that the bearing plate 17 can displace horizontally to absorb the seismic energy in the horizontal direction, and the elastic support column can be used to absorb the seismic energy in the horizontal direction.

In this embodiment, the supporting columns and the elastic connecting columns are radially arranged, a spring 4 is provided between the supporting columns 2 and the elastic connecting columns 5, and the supporting columns 12 are connected to the elastic connecting columns. Springs 10 are provided between the columns 9, and springs 6 and 8 are provided between the elastic connecting columns 5, 7, and 9; these springs can keep the horizontal positions of the supporting columns and the elastic connecting columns relatively fixed, and can further absorb the horizontal direction. vibration energy.

In this embodiment, the rolling layer includes rollers 19 arranged in the horizontal direction and grooves 18 for preventing the rollers from splashing. The rollers 501 can be made of hard alloy steel; the grooves 502 can stabilize rolling The relative distance between the pieces prevents them from splashing when suddenly subjected to violent vibrations.

In this embodiment, the support columns 2 and 12 are lead columns, so as to ensure that the building will not swing violently when there is moderate damping to resist the slight vibration of the foundation.

In this embodiment, hollow pads 3, 11 are provided between the supporting columns 2, 12 and the bearing plate 17, and hollow pads 15, 11 are provided between the connecting plate 13 and the mounting seat 16. 21. When the force in the vertical direction is small, the connecting plate is supported by the support columns 2 and 12. When the force in the vertical direction is too large, the hollow pad is crushed, and the elastic support columns 5, 7, 9 Support the connecting plate and buffer the impact received in the vertical direction at the same time.

Finally, it is noted that the above embodiments are only used to illustrate the technical solutions of the present utility model without limitation. Although the utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the utility model can be Modifications or equivalent replacements of the technical solutions without departing from the purpose and scope of the technical solutions of the utility model shall be covered by the claims of the utility model.
