A building seismic resistant base structure and use method thereof

Abstract

The present invention relates to the field of building base structures. The present invention discloses an earthquake-resistant base structure for a building and a method for using the same. The problem to be solved by the present invention is that when a building is impacted by a natural disaster such as an earthquake or a mudslide and tilts to one side, the base at the bottom thereof will inevitably tilt synchronously with the tilt of the building and gradually sink into the foundation of the building. Due to its own heavy weight, the traditional base cannot suppress the sinking trend once it sinks into the foundation of the building, and eventually sinks deeper and deeper, resulting in poor earthquake resistance. The present structure utilizes the impact force of the tilt and sinking of the base, and uses the impact force to feed back to the base in real time to quickly adjust it back to a horizontal state, thereby avoiding the effect of the building tilting at a large angle.

[0009] Preferably, the area of ​​the bottom surface of the base is slightly larger than the area of ​​the top surface of the earthquake-resistant box body, a portion of the base longer than the earthquake-resistant box body is provided with a plurality of bolt holes at intervals, and the base is fixed to the building foundation by bolts passing through the bolt holes.

[0010] Preferably, the top edge of the shock-resistant box body is made of rubber material.

[0011] Preferably, the method for using the earthquake-resistant building base structure comprises the following steps:

[0012] S1: An installation groove that is consistent with the size of the earthquake-resistant box body and is used to accommodate the earthquake-resistant box body is provided on the building foundation. When installing the base, the earthquake-resistant box body and the device inside it are first installed in the installation groove, and then the base is installed on the top surface of the earthquake-resistant box body and located on the building foundation. The bottom of the base is hinged to the upper end of the supporting leg, and the part of the base that is longer than the earthquake-resistant box body is provided with multiple bolt holes. Bolts are passed through the bolt holes to fix the base to the building foundation, thereby realizing the installation of this earthquake-resistant structure.

[0013] S2: When one side of the building is impacted and the impact force is too great, causing the building to tilt toward the other side, the base at the bottom will also tilt downward synchronously, and drive the inclination angles of the two supporting legs on the tilted side to gradually increase, while the inclination angles of the two supporting legs on the other side to gradually decrease. During the tilting process, the anti-seismic feedback bracket on the side of the bottom tilting downward is driven to gradually descend. When the base tilts downward toward the first connecting rod and the second connecting rod, the anti-seismic feedback bracket close to the first connecting rod and the second connecting rod gradually descends, and the two ends of its bottom gradually contact the side ends of the first connecting rod and the second connecting rod. During the contact process, as the anti-seismic feedback bracket descends, the hypotenuse at the bottom of the anti-seismic feedback bracket cooperates with the hypotenuse at the side ends of the first connecting rod and the second connecting rod, thereby synchronously moving the first connecting rod and the second connecting rod away from the opposite side with the hinge as the axis. The second hinge frame simultaneously slides in the second slot to raise the top height of the supporting leg, thereby raising the height of the downwardly tilted end of the base, so that the base is lifted up and restored to a horizontal state at the moment it is tilted by force, and according to the characteristics of the parallelogram, the first connecting rod and the second connecting rod can drive the third connecting rod and the fourth connecting rod on the other side to move synchronously while moving, so as to realize the synchronous rotation of the two supporting legs on the other side, and then pull down the other end of the base that is tilted, further helping the base to restore to a horizontal state, and at the same time, with the cooperation of the first spring and the second spring, the four supporting legs also return to their initial tilt angle to facilitate subsequent earthquake-resistant operations.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In the present invention, when the device is in use, when one side of the building is impacted and the impact force is too large, causing the building to tilt toward the other side, the base at the bottom will also tilt downward synchronously, and drive the inclination angle of the four force feedback anti-seismic support leg assemblies connected to the bottom to gradually increase. During the tilting process, the anti-seismic feedback bracket on one side of the bottom tilting downward is driven to gradually descend, and the anti-seismic components are symmetrically adjusted to be a parallelogram that can produce symmetrical deformation. During the descent of the anti-seismic feedback bracket, the two ends of its bottom respectively squeeze the two sides of the parallelogram to make it expand outward, thereby driving the four sides of the parallelogram to expand outward synchronously. The four force feedback anti-seismic leg assemblies at the side ends are respectively contacted and pushed in the opposite direction of their tilting direction, thereby raising the top height of the force feedback anti-seismic leg assembly, thereby raising the height of the downward tilted end of the base, and pulling the upward tilted end of the base downward, so that the base uses the force generated by its tilt to drive itself to gradually restore to a horizontal state. At the same time, the four force feedback anti-seismic leg assemblies also restore to their initial tilt angles to facilitate subsequent anti-seismic operations. This structure utilizes the impact force of the tilt and sinking of the base, and uses the impact force to feed back to the base to quickly adjust it back to a horizontal state, so as to avoid the effect of the building tilting at a large angle.

[0016] In the present invention, when one side of the building is impacted and the impact force is too great, causing the building to tilt toward the other side, the base at its bottom will also tilt downward synchronously, and drive the inclination angles of the two supporting legs on the inclined side to gradually increase, while the inclination angles of the two supporting legs on the other side to gradually decrease. During the tilting process, the anti-seismic feedback bracket on the downwardly inclined side of its bottom is driven to gradually descend. When the base tilts downward toward the direction of the first connecting rod and the second connecting rod, the anti-seismic feedback bracket close to the first connecting rod and the second connecting rod gradually descends, and the two ends of its bottom gradually contact the side ends of the first connecting rod and the second connecting rod. During the contact process, as the anti-seismic feedback bracket descends, the hypotenuse at the bottom of the anti-seismic feedback bracket cooperates with the hypotenuse at the side ends of the first connecting rod and the second connecting rod, thereby causing the first connecting rod and the second connecting rod to rotate synchronously in a direction away from the opposite side with the hinge as the axis. During the movement of the first connecting rod and the second connecting rod, they respectively push the brackets located there The supporting legs on both sides push it from an inclined state to a nearly straight state, and the second articulated frame slides synchronously in the second slot, thereby raising the top height of the supporting legs, thereby raising the height of the downwardly inclined end of the base, so that the base is lifted up and restored to a horizontal state at the moment it is tilted by force, and according to the characteristics of the parallelogram, the first connecting rod and the second connecting rod move while driving the third connecting rod and the fourth connecting rod on the other side to move synchronously, so as to realize the synchronous rotation of the two supporting legs on the other side, and then pull down the other end of the base that is tilted, further helping the base to restore to a horizontal state, and at the same time, with the cooperation of the first spring and the second spring, the four supporting legs also return to their initial inclination angle to facilitate subsequent earthquake-resistant operations. This structure utilizes the impact force of the tilt and sinking of the base, and uses the impact force to feed back to the base to quickly adjust it back to a horizontal state, so as to avoid the effect of the building tilting at a large angle.

[0017] In the present invention, by setting up a sliding frame, when the first connecting rod and the second connecting rod, the third connecting rod and the fourth connecting rod respectively rotate at the hinges, the hinges of the first connecting rod and the fourth connecting rod, the second connecting rod and the third connecting rod simultaneously slide in the direction away from the opposite side, thereby achieving uniform expansion or contraction of the parallelogram formed by them, thereby ensuring the stability of the synchronous push of the four supporting legs.

[0018] In the present invention, an installation groove which is consistent with the size of the earthquake-resistant box body and is used to accommodate the earthquake-resistant box body is provided on the building foundation. When installing the base, the earthquake-resistant box body and the device inside it are first installed in the installation groove, and then the base is installed on the top surface of the earthquake-resistant box body and located on the building foundation. The bottom of the base is hinged to the upper end of the supporting leg, and the part of the base which is longer than the earthquake-resistant box body is provided with a plurality of bolt holes. Bolts are passed through the bolt holes to fix the base to the building foundation, thereby realizing the installation of the earthquake-resistant structure.

[0019] In the present invention, by setting the edge of the top surface of the earthquake-resistant box body to a rubber material with good ductility, when the building is tilted to one side by the impact force, causing the base to tilt downward and squeeze the top surface of the earthquake-resistant box body, if hard materials are used, it is easy to be damaged. However, by using rubber material, the top surface of the earthquake-resistant box body is squeezed and deformed at the same time, which can effectively extend the service life of the earthquake-resistant box body.
