Abstract

The utility model relates to a kind of composite foundation base, described foundation comprises building base plate, basic raft plate and pile tube, rolling steel ball is set between the bottom of groove and shock insulation stake and can effectively absorbs the lateral force that earthquake produces, the hardcore bed between basic raft plate and pile tube can be resisted larger shear strain; So when building superstructure is in the time being subject to horizontal thrust, hardcore bed shear strain produces integral level displacement, can reduce like this local failure, therefore earthquake is weakened greatly to the horizontal destructive power of building.

Description

A kind of composite foundation base
Technical field
The utility model relates to a kind of foundation, relates in particular to a kind of composite foundation base.
Background technology
For a long time, traditional building foundation shape adopts the foundation of larger bottom surface area mostly, 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
In order to overcome the deficiency of foundation anti-seismic performance in prior art, the utility model provides the composite foundation base that a kind of anti-seismic performance is good.
The technical solution of the utility model is: a kind of composite foundation base, described foundation comprises building base plate, basis raft plate and pile tube, it is characterized in that: building backplanes support upper building, building base plate bottom surface arranges shock insulation stake, the bottom of shock insulation stake is inverted bucking ladder shape, basis raft plate is the armored concrete slab of 50 centimetres of thickness, the bucking ladder shape groove that the upper surface setting of basis raft plate and the bottom shape of shock insulation stake match, between the bottom of groove and shock insulation stake, rolling steel balls is set, below the raft plate of basis, pile tube is set, between basis raft plate and pile tube, the hardcore bed of 15 centimetres is set, pile tube upper end arranges pile tube cuff, pile tube cavity is filled steel concrete, the circular steel plate shutoff of 3 millimeters thick for pile tube bottom.
The beneficial effects of the utility model: between groove and the bottom of shock insulation stake, rolling steel ball is set and can effectively absorbs the lateral force that earthquake produces, the hardcore bed between basic raft plate and pile tube can be resisted larger shear strain; So when building superstructure is in the time being subject to horizontal thrust, hardcore bed shear strain produces integral level displacement, can reduce like this local failure, therefore earthquake is weakened greatly to the horizontal destructive power of building.
