The utility model provides a quakeproof and deformation-proof foundation structure, and fig. 1 is a schematic diagram of the foundation structure provided by the embodiment of the application; fig. 2 is a schematic structural diagram of a shock-absorbing corner provided in an embodiment of the present application.

Referring to fig. 1, the foundation structure includes a lower ground beam 7, an upper ground beam 10, a foundation beam 5, a reinforcing steel bar net frame 3, a concrete layer 6, a shock absorption angle 2 and a protection pier 1.

In this application, go up the floorbar 7 and lay under the earth's surface, set up damping groove 4 at the interval of the top on the floorbar 7 down, have corresponding with the floorbar 7 and have last floorbar 10, go up the floorbar 10 bottom surface and set up the spacing draw-in groove 11 that corresponds with basic roof beam 5 top, basic roof beam 5 is laid in the direction perpendicular with going up floorbar 7, last floorbar 10, and its lower extreme is inserted and is established in damping groove 4, and its upper end is inserted and is established in spacing draw-in groove 11. A steel bar net 3 is fixedly connected to the outside of the foundation beam 5, and the steel bar net 3 is confined between the lower ground beam 7 and the upper ground beam 10, and concrete is poured into the steel bar net 3 to form a concrete layer 6. Protection piers 1 are arranged at the edges of a concrete layer 6 and an underbeam 7, and damping corners 2 are clamped at the corners between the concrete layer 6 and the protection piers 1. The protective pier 1 is formed by mixing, pouring and molding cement and sand stone during manufacturing, and the obtained protective pier 1 has high hardness and good durability. In the foundation structure of this application, the lower ground beam 7 that main body frame includes, go up ground beam 10, foundation beam 5 and shock attenuation angle 2 are reinforced concrete structure, can be so that foundation structure overall structure intensity is high, bearing capacity is strong.

Referring to fig. 2, the shock-absorbing horn 2 includes a first stopper 14, a second stopper 16, a first shock-absorbing plate 13, and a second shock-absorbing plate 17.
