Abstract

The utility model relates to a shock insulation pile foundation. The shock insulation pile foundation comprises a pile column, a foundation beam and a foundation located on the lower portion of the foundation beam, wherein the foundation is located at the top of the pile column, and a shock insulation device is arranged between the foundation beam and the foundation. The laminated shock insulation support seat of the shock insulation pile foundation disclosed by the utility model is formed by superposing multilayer steel plates and multilayer rubber layer by layer ay intervals, and the rubber layers are mutually bonded with the steel plate layers, thus the seismic bearing capacity of a building can be effectively improved, the disaster brought by seism can be reduced, and the seismic capacity is high.

Description

A kind of shock insulation pile foundation

Technical field

The utility model relates to a kind of isolation structure, relates in particular to a kind of shock insulation pile foundation.

Background technology

For a long time, traditional building lot shape foundations that adopt the area of going to the bottom more greatly more, improve the load force of ground with this, but this structural seismic capacity is poor, when earthquake, the impact of the seismic wave energy that curstal fault or displacement cause is directly being born in the bottom surface of foundation, floor space is larger, the dynamics being directly hit and fracture, the possibility of displacement is just larger, therefore its antidetonation effect is just poor, process identical in the earthwork, use in the situation of capital construction material similarly, in order to improve the shock resistance of building foundation, also adopt the foundation of the area of going to the bottom more greatly, cannot realize the object of expection, especially in the multiple area of earthquake, its foundation has been proposed to higher shockproof requirements.

Summary of the invention

The utility model provides a kind of shock insulation pile foundation.

For achieving the above object, the technical solution adopted in the utility model is: a kind of shock insulation pile foundation, comprise pile, grade beam and be positioned at the basis of grade beam bottom, pile is helical burr ram, the lower end of helical burr ram is provided with circular shoe, the external surface that spiral lamination protrudes from helical burr ram extend in foundation soil, basis is positioned at helical burr ram top, between grade beam and basis, earthquake isolating equipment is set, earthquake isolating equipment comprises laminated shock isolation support, upper junction plate, lower connecting plate and guide hydraulic post, laminated shock isolation support is to be formed by stacking by multilayer steel plates and multilayer rubber wall layer, together with rubber layer is adhered to one another with steel plate layer, laminated shock isolation support upper, soffit is fixedly connected with the soffit of upper junction plate and the upper surface of lower connecting plate respectively, guide hydraulic post is arranged between upper junction plate and lower connecting plate by spherical linkage, upper junction plate is fixedly connected with basis with grade beam respectively with lower connecting plate.

The utility model is owing to having adopted pile foundation structure, basis is positioned at pile top, make the center of gravity on whole basis, all the time drop within the scope of the bottom surface of base center, when earthquake, the seismic wave that basic bottom surface is impacted is guided basic periphery into and is weakened, and can use homogeneity, make basic in the situation that with amount constructional materials, strengthen the frictional resistance between basis and soil layer, improve Seismic Bearing Capacity.

The utility model has also adopted laminated shock isolation support, laminated shock isolation support is to be formed by stacking by multilayer steel plates and multilayer rubber wall layer, together with rubber layer is adhered to one another with steel plate layer, make laminated shock isolation support there is very large vertical bearing capacity and vertical stiffness, it is less that laminated shock isolation support also has horizontal rigidity, the feature that horizontal limeit distortion is larger, can resist larger shear strain; So when building superstructure is in the time being subject to horizontal thrust, utilize laminated shock isolation support to produce integral level displacement compared with large shear strain, can reduce like this local failure, therefore earthquake is weakened greatly to the horizontal destructive power of building.
