Abstract
The utility model relates to an anti-seismic foundation which comprises a group pile, a foundation beam and a foundation body arranged under the foundation beam. The foundation body is arranged on the top of the group pile. An Anti-seismic device is arranged between the foundation beam and the foundation body. The group pile is provided with two or more than two secondary pile columns. A main pile column is arranged in the center of the group pile. The secondary pile columns are symmetrically arranged around the main pile column. The anti-seismic device comprises a foundation mat arranged on the foundation body, and a foundation beam bottom plate arranged under the foundation beam. The foundation mat and the foundation beam bottom plate are horizontal quenching steel plates. A ball layer is arranged between the foundation mat and the foundation beam bottom plate. The ball layer is a single-layer array formed by laying a plurality of quenching steel balls. The group pile enhances the frictional resistance between the integral foundation and the ground, the stress and the bearing force of the foundation are improved, the anti-seismic device can effectively prevent earthquakes and has the buffering effect on damage caused by the earthquakes, disasters caused by the earthquakes can be reduced, and the anti-seismic capacity is high.
Description
Technical field
The utility model relates to a kind of earthquake resistant structure, relates in particular to a kind of earthquake proof 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, during earthquake, the impact of the seismic wave energy that earth's crust fracture or displacement cause is directly being born in the bottom surface of foundation, floor space is larger, the dynamics directly be hit and fracture, the possibility of displacement is just larger, therefore its antidetonation effect is just poor, in the earthwork, process identical, 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, can't realize the purpose 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 earthquake proof foundation.
For achieving the above object, the technical solution adopted in the utility model is: a kind of earthquake proof foundation, comprise a clump of piles, grade beam and be positioned at the basis under grade beam, basis is positioned at clump of piles top, in the middle of grade beam and basis, vibration abatement is set, it is characterized in that: a described clump of piles is provided with secondary pile more than two, also be provided with a king pile post at this clump of piles center, secondary pile is arranged symmetrically in around the king pile post, the intensity of king pile post is greater than the intensity of secondary pile in this clump of piles, in this clump of piles by described king pile post the secondary pile to clump of piles periphery, its intensity weakens gradually, between secondary pile and king pile post, with collar tie beam, be connected, described vibration abatement comprises the sole plate that is arranged on basis and is arranged at the grade beam base plate below grade beam, sole plate and grade beam base plate are horizontal quenched nickelclad, steel bar welding in sole plate and basis is connected together, steel bar welding in grade beam base plate and grade beam is connected together, between sole plate and grade beam base plate, it is the ball layer, the array formed by a plurality of quenching steel ball tilings that the ball layer is individual layer, filling flexible padded coaming around the ball layer.
The utility model is owing to having adopted upper surface to be greater than the Toft foundation structure of bottom surface, and the center of gravity of whole foundation, all the time drop in the bottom surface scope at foundation center, when this not only can be by earthquake, the periphery that the seismic wave that the foundation bottom surface is impacted is guided foundation into weakens, and a kind of round platform of likeness in form inverted steps shape or the structure of terrace with edge have been adopted, can be in the situation that use homogeneity, same amount constructional materials to make ground, strengthen the frictional resistance between whole ground and ground, improve its stress and load force.
The utility model construction is safer, and the duration is shorter, cost is lower, under applicable geological condition, is the better building lot of anti seismic efficiency.In addition, between basis and grade beam due to the rolling action of ball layer, the horizontal force that the horizontal jitter that earth's surface occurs produces is difficult to be sent on building body, earthquake only becomes the force of rolling friction between the quenching steel ball to the horizontal force of building, during earthquake, the horizontal destructive power of the major part of the horizontal movement of the earth is difficult to pass to building by ground, so earthquake is weakened greatly to the horizontal destructive power of building.
