It is detached from floor beam when dynamic.
Preferably, on the upside of the supporting block antifriction piece is provided between groove upper side wall.
By using above-mentioned technical proposal, friction when supporting block level is slided between terraced body is reduced by antifriction piece
Power, to reduce horizontal stress of the supporting block to terraced body.
Preferably, the terraced body longitudinal sliding motion is connected to hanging beam, and the cunning slided for hanging beam is provided on the ladder body
Slot.
By using above-mentioned technical proposal, terraced body can horizontal longitudinal sliding motion, agent structure is to the water of terraced body when reducing earthquake
Horizontal stress.
Preferably, the supporting block and floor beam one-piece casting.
By using above-mentioned technical proposal, the bonding strength of supporting block and floor beam is improved, to improve supporting block to ladder
The support strength of body.
Preferably, the fixture block is integrally formed with hanger bar.
By using above-mentioned technical proposal, the bonding strength of fixture block and hanger bar is improved, to promote hanger bar to terraced body
Support strength.
Preferably, the snubber elastomeric part is rubber pad.
By using above-mentioned technical proposal, when earthquake, cushioning effect is played by rubber pad.
In conclusion the utility model has the advantages that：
1, terraced body upper end is supported by supporting block, terraced body is horizontally slidable, simultaneously support block have move up and down
Space, floor beam prevents terraced body from caving in the active force of terraced body vertical direction when to reduce earthquake；
2, while being supported to terraced body upper end by hanger bar, hanger bar will not be completely fixed terraced body, and terraced body can be
Horizontal sliding in a certain range, stress of the agent structure to terraced body when reducing earthquake.
