Technical Field

[0001] The invention relates to the field of earthquake-resistant buildings, and in particular to an earthquake-resistant building structure and an earthquake prevention system thereof. Background Art

[0002] Earthquakes are a serious natural disaster that has caused heavy casualties and irreparable property losses. At present, humans cannot accurately predict earthquakes, and the more advanced earthquake prediction methods can only provide early warning of earthquakes a few tens of seconds in advance. It is difficult for people to know in advance that an earthquake will occur and escape from buildings in time. Therefore, it seems that earthquake prevention from the perspective of earthquake prediction is not very effective.

[0003] The existing patent CN106121337B discloses an earthquake-resistant building for shielding and waveguiding earthquake waves, including a building body, a shielding layer for filtering earthquake waves, and a waveguide device, wherein the shielding layer is located at the base layer where the building body is located, and the waveguide device includes a waveguide column, one end of the waveguide column is arranged at the base layer and is located between the shielding layer and the building body, and the other end is arranged outside the base layer.

[0004] It only uses a shielding layer to filter seismic waves, and its actual anti-seismic effect is limited, especially in the direction of the building's own weight. It often shows the characteristics of impact damage during an earthquake. At this time, the bottom foundation of the building is often difficult to achieve a good balance between effective support and active earthquake resistance.

[0005] There is a need for an earthquake-resistant building structure and an earthquake prevention system thereof to solve the above problems. Summary of the invention

At this time, the bottom foundation of the building often finds it difficult to achieve a good balance between effective support and active seismic resistance. A building seismic structure and an earthquake prevention system are provided to solve the above problems.

[0007] The present invention provides an earthquake-resistant building structure and an earthquake prevention system thereof, comprising a temporary support mechanism, a vibration starting mechanism, a constant force support mechanism, a shielding layer, a transverse plate mechanism and an edge limiting mechanism, wherein the shielding layer is a hard rectangular pit, the upper edge of the shielding layer is lower than the ground height, the constant force support mechanism is a vertical rigid body, evenly arranged on the bottom surface of the shielding layer, the transverse plate mechanism is arranged on the top of the constant force support mechanism, and is rigidly connected to the constant force support mechanism, the bottom surface of the edge of the transverse plate mechanism contacts the top surface of the outer periphery of the shielding layer, the outer side surface of the transverse plate mechanism contacts the edge limiting mechanism, and the edge limiting mechanism is The bottom surface is a rigid structure with an inclined surface. The edge limiting mechanism decreases in vertical height from the contact end with the transverse plate mechanism to the outer end. The top surface of the edge limiting mechanism, the ground, and the top surface of the transverse plate mechanism are coplanar. The top surface of the edge limiting mechanism, the ground, and the top surface of the transverse plate mechanism are connected to form an integral structure through concrete. The starting end of the vibration starting mechanism is arranged on the bottom surface of the transverse plate mechanism, and the temporary supporting mechanism is arranged between the transverse plate mechanism and the bottom surface of the shielding layer. The temporary supporting mechanism is a supporting mechanism with adjustable supporting angle, and the adjusting end of the supporting angle of the temporary supporting mechanism is connected to the working end of the vibration starting mechanism.

[0008] The earthquake-resistant building structure and earthquake prevention system thereof described in the present invention are, as a preferred embodiment, a vibration starting mechanism including an air chamber, a connecting rod, and a starting rack. The connecting rod is a rod structure, and the starting rack is a single-sided rack. An air chamber is arranged at the top of the starting rack, and the air chamber opening is arranged at the end of the starting rack. The lower end of the connecting rod is a piston that passes through the air chamber opening and is arranged inside the air chamber. A through hole is arranged on the side of the air chamber, and the other end of the connecting rod is connected to the ball head on the bottom surface of the transverse plate mechanism.

[0009] The earthquake-resistant building structure and earthquake prevention system thereof described in the present invention, as a preferred embodiment, the temporary support mechanism includes a limit block, a gear, a screw, a slide, a pad, a slider, a fluid pressure support rod, a first ball head and a second ball head, the pad is arranged at the bottom of the transverse plate mechanism, the slide is arranged at the lower surface of the pad, the slider is arranged inside the slide, the slider is provided with a screw hole along the direction of the slide, the screw is arranged through the screw hole, one end of the screw is keyed to the gear and rotatably connected to the limit block on the inner side of the gear, the gear is meshed with the starting rack, the limit block limits the meshing relationship between the starting rack and the gear, the first ball head and the second ball head are respectively arranged at the two ends of the fluid pressure support rod, the fluid pressure support rod is a movable lifting rod structure, the lifting of the fluid pressure support rod is fluid compression lifting, the first ball head is arranged on the lower surface of the slider, the second ball head is arranged on the bottom surface of the shielding layer, and when the slider is at the farthest position, the vertical projection of the first ball head and the vertical projection of the second ball head coincide with each other.

[0011] When an earthquake occurs, the angle of the vibration-starting mechanism changes, causing the connecting rod to move toward the inside of the air chamber of the rack. If the shaking is small, the air chamber will be exhausted through the small hole, but the rack may not be. If the shaking is large, the connecting rod will be inserted instantly, and the gas in the rack will be difficult to be quickly discharged through the small hole. The movement of the rack drives the gear to rotate, and the rotation of the gear drives the slider to move toward the far end, causing the fluid pressure support rod to tend to be vertical. At this time, the space in the fluid cavity in the support rod is reduced, the supporting force becomes larger, and the support angle tends to be vertical, providing instantaneous support.

[0012] The beneficial effects of the present invention are as follows:

[0013] The anti-seismic system of the present invention is a two-stage anti-seismic system. The mutual limiting and movable relationship between the constant force support part and the horizontal plate enables the horizontal plate to have a certain degree of freedom of movement, thereby avoiding direct damage to the concrete structure. At the same time, according to the temporary support mechanism, temporary high-strength force support is provided when a large vibration occurs. This device is triggered based on the earthquake intensity, avoiding the problem of deformation failure of long-term support and the problem of large instantaneous impact when triggered.
