First spring 33 removes to structural slab 31 along vertical direction and plays the cushioning effect for structural slab 31 and superstructure are difficult for taking place great vertical rocking, and then have reduced the inside damage that causes because of rocking of building, have improved the shock resistance of building.
In order to further improve the structural stability of the earthquake-resistant building under the action of an earthquake, as shown in fig. 2, one end of the splicing column 32, which is positioned at the lower side of the foundation plate 41, is fixedly connected with a tensile pull head 322, and the splicing hole 413 plays a limiting role in limiting the tensile pull head 322. Tensile pullout 322 can't pass spliced eye 413, consequently to having played limiting displacement for the vertical displacement of spliced pole 32, takes place to damage and can't play the pulling force effect to structural slab 31 when chain 13, and tensile pullout 322 plays limiting displacement to structural slab 31's vertical displacement for structural slab 31 can't separate with foundatin plate 41, consequently strengthens the stability of being connected between structural slab 31 and the foundatin plate 41.
In order to further reduce the vibration of the structural plate 31, as shown in fig. 2, a second spring 323 is fixedly connected between the tensile pulling head 322 and the base plate 41, and the second spring 323 is arranged in a direction perpendicular to the base plate 41. When structural slab 31 rocked along with the water flow in the earthquake process, vertical displacement takes place for foundatin plate 41 for plug column 32, and second spring 323 takes place deformation this moment, and the spring action of second spring 323 has played the cushioning effect to structural slab 31's removal, consequently makes structural slab 31 and superstructure 2 be difficult for taking place great vertical displacement, has consequently further improved shock insulation structure's vertical shock insulation ability.
In order to further buffer the impact of water flow on the structural plate 31 when the structural plate 31 moves along with the water storage tank 51, as shown in fig. 2, a plurality of buffer springs 35 with a buffering effect are arranged between the structural plate 31 and the base plate 41, in order to facilitate the installation of the buffer springs 35, a support table 34 is fixedly arranged on one side of the base plate 41 close to the structural plate 31, the support table 34 comprises a support plate 341 and a support frame 342, the buffer springs 35 are fixedly connected to one side of the support plate 341 close to the structural plate 31, and the buffer springs 35 are arranged along a direction perpendicular to the structural plate 31 and fixedly connected between the structural plate 31 and the support plate 341, so that the impact of water flow on the structural plate 31 can be further buffered. Set up brace table 34 and make things convenient for the staff to fix a plurality of buffer spring 35 and set up between brace table 34 and structural slab 31, when structural slab 31 takes place to rock along with the flow of rivers during the earthquake, buffer spring 35's elasticity effect plays the cushioning effect to structural slab 31's vertical migration, consequently makes the superstructure 2 of structural slab 31 top difficult emergence acutely rock and then be difficult for collapsing, has further improved the anti-seismic performance of building promptly.
The structural plate 31 can be positioned in the foundation pit 1 or above the foundation pit 1, and in order to prevent the structural plate 31 from rigidly colliding with the foundation pit 1 in the earthquake process, as shown in fig. 2, the structural plate 31 is arranged above the open side of the foundation pit 1, and the structural plate 31 can shield the water storage tank 51. Through the height of 52 positions of water in the control aqua storage tank 51, can be so that the structural slab 31 is located foundation ditch 1 top, structural slab 31 shelters from aqua storage tank 51, consequently makes aqua storage tank 51 be difficult for interfering the building of its top building, and foundation ditch 1 is difficult for interfering the horizontal displacement of structural slab 31 simultaneously.
When the lateral wave of an earthquake acts, the structural plate 31 may shake in the horizontal direction, and in order to buffer the horizontal vibration of the structural plate 31 relative to the ground 6, as shown in fig. 2, the communication groove 61 is formed in the ground 6, the communication groove 61 is communicated with the outer side edge of the foundation pit 1, the structural plate 31 is positioned in the communication groove 61 and above the communication groove 61, the horizontal spring 62 is fixedly connected between the side wall of the communication groove 61 and the side wall of the structural plate 31, the horizontal spring 62 is arranged on the outer side edge of the structural plate 31 in the horizontal 52 direction, and the horizontal spring 62 is in a compressed state. The horizontal spring 62 has a buffering effect on the shaking of the structural plate 31 relative to the ground 6, so that the structural plate 31 is prevented from rigidly colliding with the ground 6, the damage of earthquake transverse waves to the building is reduced, and the earthquake resistance of the building is improved.
The working principle of the invention is as follows:
when no earthquake occurs, the bearing pile 311 and the structural plate 31 float in the water storage tank 51 under the action of buoyancy of water 52 and self gravity of the superstructure 2 and keep a balanced state, and the inserting column 32 is inserted and matched with the foundation plate 41, so that the structural plate 31 is limited in the horizontal direction, and the superstructure 2 can be kept immovable relative to the ground 6; when an earthquake occurs, when the foundation pit 1 vibrates under the vibration of transverse waves and longitudinal waves of the earthquake, the water 52 in the water storage tank 51 shakes, the inserting column 32 can vertically displace relative to the foundation plate 41, so that the bearing pile 311 can float along with the flow of the water 52, the conduction effect of the vibration waves during the earthquake is greatly weakened through the buffering effect of the water 52, the collapse of the upper building 2 caused by the fracture due to the collision between the bearing pile 311 and the foundation is avoided, when the structural plate 31 vibrates horizontally relative to the lower buttress 412 through the inserting column 32, the vibration isolation support 42 deforms to attenuate the energy of the transverse waves of the earthquake, and the elasticity of the horizontal spring 62 plays roles of buffering and resetting on the horizontal displacement of the structural plate 31; meanwhile, when the structural plate 31 vibrates vertically relative to the foundation plate 41, the first spring 33, the second spring 323, the buffer spring 35 and the shaking of the structural plate 31 and the superstructure 2 in the water 52 play a role in further buffering, so that the energy of transverse waves and longitudinal waves of an earthquake is attenuated, and the earthquake resistance of the building is further improved.
