Abstract
The utility model relates to the technical field of the building, and in particular to a single-layer ball-bearing-type earthquake-proof foundation, which consists of a foundation main body, a cover plate, a foundation soleplate, a ball-bearing layer, a foundation ditch soleplate and a retaining wall, wherein the foundation main body is arranged inside a foundation ditch, and the shoulder part of the foundation main body and the upper surface of the edge of the foundation ditch are covered by the cover plate. The bottom part of the foundation main body is provided with the foundation soleplate which is integrated with the reinforcing steel bars in the foundation main body into a whole body in a welding way, and the foundation soleplate is a horizontal hardened steel plate. The foundation ditch soleplate is anchored on the bottom part of the foundation ditch and is also a horizontal hardened steel plate. The ball-bearing layer is arranged between the foundation soleplate and the foundation ditch soleplate. The ball-bearing layer is of a single-layer array which is formed by tiling a plurality of hardened steel balls. The retaining wall is arranged on four walls of the foundation ditch. By adopting the single-layer ball-bearing-type earthquake-proof foundation, the horizontal force which is applied by the earthquake to the building is only the rolling friction force between the hardened steel balls, thereby greatly weakening the horizontal damage force of the earthquake to the building.
Description
Technical field
The utility model relates to technical field of buildings, particularly relates to a kind of individual layer ball-type earthquake proof foundation.
Background technology
Horizontal seismic force is main to the harm of building, one because of the earthquake centre point horizontal amplitude of vibration in vast earthquake district in addition much larger than vertical amplitude of vibration; Two have enough knowledge to vertical gravity because of people, so bigger surplus capacity opposing vertical seismic force is generally arranged, and horizontal shearing resistance is the weak link of building, this is that the own shear strengths of member such as brick, concrete are far smaller than compressive strength, adding level more generally is straight joint, mortar and with the adhesive strength of masonries such as brick often less than due to the reasons such as masonry.
The patent No. is that 00112457.9 " the anti-macroseism of slippage building foundation " utilizes two shiny surfaces that are in contact with one another to slide mutually when earthquake and reach and weaken the effect of earthquake to the horizontal destructive power of building.This scheme has following defective:
1. the friction factor of shiny surface is low inadequately.Mention in this application and adopt concrete waxing or plastic sheeting, plastic plate to serve as shiny surface, even and concrete adopts waxing or apply oil, its friction factor is reduced significantly, and the most smooth polytetrafluoroethylene (PTFE) in the plastics, its friction factor is also between 0.04-0.1.
2. the relative motion mode of two shiny surfaces has adopted sliding type.The coefficient of sliding friction is much larger than coefficient of rolling friction.
3. the intensity on shiny surface surface is low, because what bear between two shiny surfaces is the pressure of whole building, the plastic sheeting on two shiny surface surfaces, plastic plate or the smooth surface layer that forms with the concrete waxing are under huge pressure, when motion, can produce huge frictional force and destroyed, such result is that the friction factor of two shiny surfaces increases greatly, reduces anti seismic efficiency.
The patent No. is 02110560.X's " a kind of Antiseismic building foundation " ball layer of utilizing material such as quenching steel ball to form, utilized the less advantage of coefficient of rolling friction, but its ball layer is not an individual layer, but the accumulation body of many pearls, promptly the centre of sphere connecting line of adjacent ball might not be a horizon.This just makes steel ball is not the horizontal movement that layering takes place under the effect of earthquake horizontal force, but mutual collision that takes place and disorderly motion.Form relative horizontal movement relation between the steel plate on ball layer and upper strata substantially, but under horizontal force action, be in the ball of ball layer upper surface, its bottom rubs with a plurality of balls that contact with it, inhibition has been played in its rolling, also reduced anti seismic efficiency.
The utility model content
The utility model is for solving the deficiencies in the prior art, provides between a kind of ground and the foundation ditch bottom surface frictional force minimum, when earthquake, the individual layer ball-type earthquake proof foundation of free horizontal movement can take place between ground and the foundation ditch bottom surface.
The scheme that solves the utility model technical problem is: individual layer ball-type earthquake proof foundation by foundation body, cover plate, substrate plate, ball layer, base plate of foundation pit and retaining wall constitute.Wherein, foundation body is in the foundation ditch, and the edge upper surface of the shoulder of foundation body and foundation ditch is stamped cover plate.The bottom of foundation body be with foundation body in the ground substrate plate that is welded as a whole of reinforcing bar, the ground substrate plate is horizontal quenched nickelclad.Base plate of foundation pit is anchored in the foundation ditch bottom, also is horizontal quenched nickelclad.Between ground substrate plate and the base plate of foundation pit is the ball layer.The ball layer is the array that is formed by the tiling of a plurality of quenching steel balls of individual layer.Retaining wall is positioned at the wall of foundation ditch, and retaining wall and ground, leave the space between the edge of substrate plate and ball layer.
Adopt such scheme, can reach following effect:
1. during earthquake, because building its own inertial, add between ground basal surface and the pit foundation bottom surface because the rolling action of ball layer, the horizontal force that horizontal jitter produced that the face of land takes place is difficult to be sent on the building body, earthquake only becomes force of rolling friction between the hardened steel to the horizontal force of building, so earthquake is weakened greatly to the horizontal destructive power of building.
2. because in the utility model, the resistance that overcomes because of earthquake horizontal force generation displacement between at the bottom of ground basal part and the foundation ditch is the friction between the quenching metal covering, and be rolling friction, its friction factor only is 0.001, therefore, the most of horizontal destructive power of the horizontal movement of the earth is difficult to pass to building by ground during earthquake.
3. because the utility model has adopted the quenching steel ball layer of individual layer, guaranteed between pit foundation bottom and the ground basal part free relative displacement to take place in any direction.
In sum, the utility model has played good anti seismic efficiency.
