Preferably, the three steel bar jackets are provided with expansion springs which are abutted against the two adjacent steel bar connecting sleeves.

By adopting the technical scheme, when an earthquake occurs, the extension spring can effectively absorb horizontal vibration caused by transverse waves of the earthquake by virtue of good deformation capacity, and the destructiveness of the extension spring to a house structure is reduced.

Preferably, a reinforcing steel bar four is fixed at one upper end of the reinforcing steel bar along the length direction of the wall body.

Through taking above-mentioned technical scheme, make originally independent convex steel bar structure interconnect in the wall body, steel bar structure in the wall body forms a whole, and when the earthquake takes place, the reinforcing bar in the wall body is restricted fixedly each other, makes whole house frame construction connectivity stronger, and stability is also stronger.

Preferably, rubber buffer pads are arranged outside the first reinforcing steel bars and the second reinforcing steel bars in the foundation, and the rubber buffer pads are located above the steel bar connecting sleeves. And after the steel bar connecting sleeve is embedded, the rubber cushion pad is also embedded in the foundation.

Through adopting above-mentioned technical scheme, when the earthquake takes place, utilize the elasticity absorption earthquake wave of rubber buffer pad, slow down the propagation velocity of earthquake wave in ground and wall body, simultaneously, the energy of transverse wave vibrations can be absorbed to the rubber buffer pad, reduces the influence of the earthquake transverse wave that the wall body received, reaches antidetonation effect.
