Description
Technical Field
The invention relates to the technical field of building earthquake resistance, in particular to a multi-dimensional earthquake-resistant buffer base mechanism for a building house and an implementation method thereof.
Background
Seismic waves are vibrations that propagate around a seismic source, and refer to elastic waves that radiate from the source to the surroundings. Seismic waves are mainly classified into two types, one is surface waves and the other is solid waves. Surface waves are transmitted only at the surface and the physical wave energy traverses the earth's interior.
The solid wave is divided into two types, P-wave and S-wave. P wave: p represents main or compression, and is a longitudinal wave, the vibration direction of the particles is parallel to the advancing direction of the wave front, and the advancing speed is the fastest and the earliest arriving in all seismic waves. P-wave energy is transferred in solids, liquids or gases.
S wave: s means secondary or shear, the forward velocity is second only to the P wave, and the particle vibration direction is perpendicular to the forward direction of the wave, which is a transverse wave. The S-wave can only be transmitted in a solid, but not through the liquid outer core.
The surface wave is also called L wave, and is a mixed wave generated by excitation after the longitudinal wave and the transverse wave meet each other on the earth's surface. Its wavelength is large, amplitude is strong, it can only be propagated along ground surface, so that it is the main factor for making building strongly damaged. The surface wave has the characteristics of low frequency, high amplitude and dispersion, is transmitted only near the surface and is the most powerful seismic wave.
China is located between two earthquake zones in the world, namely the Pacific earthquake zone and the Eurasian earthquake zone, and earthquake fracture zones are very active under the extrusion of Pacific plates, Indian plates and Philippine sea plates. China's earthquakes are mainly distributed in Taiwan areas, southwest areas, northwest areas, southeast coastal areas and 23 seismic bands. High-rise buildings on seismic belts are greatly affected by earthquakes. Under the action of an earthquake, a high-rise building can be impacted by transverse waves and longitudinal waves from the earthquake, the impact of the longitudinal waves is reduced by using a spherical support in the conventional earthquake-proof base, and the resonance effect generated by most earthquake waves can be avoided by sliding friction shock insulation of a spherical core on a spherical tetrafluoro plate. In addition, the friction force of the seismic isolation layer works, so that the vibration energy of the structure can be consumed, the structural damping is increased, and the structural seismic response is reduced. However, the existing spherical support only uses a stop rod or a stop ring to prevent the spherical core from being punched out of the spherical tetrafluoro plate, and the structure is too simple, so that the shock absorption of the spherical support is influenced, and the spherical support is not firm.
Chinese patent CN201821932926.4 discloses a housing construction antidetonation support, including the bottom suspension fagging, the bottom suspension fagging upside is equipped with a supporting bench, the supporting bench upper surface is equipped with the sphere recess, fixedly connected with sphere tetrafluoro plate in the sphere recess, sphere tetrafluoro plate upside is equipped with the ball core, ball core upside is equipped with plane tetrafluoro plate, plane tetrafluoro plate upside is equipped with the backup pad, it is equipped with four fan-shaped recesses to go up the backup pad lower surface, go up backup pad bolted connection have with fan-shaped recess assorted dog, be equipped with the bumper shock absorber between bottom suspension fagging and the last backup pad, the bumper shock absorber is located between two adjacent dogs, be equipped with first ball hinge between bumper shock absorber and the bottom suspension fagging. This structure has made certain improvement to current spherical base, promotes in the aspect of structural stability to some extent, has increased vertical direction's buffering in addition. But the earthquake-resistant dimension still needs to be increased when the building is applied to large buildings.

The supporting column 2 provides a supporting force in the vertical direction for the longitudinal buffer component 3, the spherical buffer component 4 and the top plate 7, so that the house on the top plate 7 is prevented from sinking. Provide the buffering for spherical surface buffering subassembly 4, roof 7 encounter the longitudinal wave in the time through setting up vertical buffering subassembly 3, reduce the influence of longitudinal wave to house superstructure. The spherical buffer component 4 can enable the top plate 7 above the spherical buffer component and the house to generate good restoring force when encountering various seismic waves such as body wave surface waves and the like through the internal spherical motion, and the vibration amplitude of the house is reduced. The floating hinge assembly 5 mainly functions to restrain the top plate 7 and the house main body on the spherical buffering assembly 4 on a horizontal plane, but still has a certain degree of freedom in a vertical direction, and avoids being damaged by radial force under the influence of longitudinal waves. Buffering rope group 8 is as the replenishment of unsteady articulated subassembly 5, draws roof 7 and house main part downwards through elasticity and makes it recover, avoids roof 7 and house to break away from sphere buffering subassembly 4, and unsteady articulated subassembly 5 plays the effect that prevents sphere buffering subassembly 4 upper and lower separation equally, makes structural stability stronger.

The longitudinal buffer assembly 3 comprises a fixed plate 3a, a guide rod 3b and a damping spring 3 c; fixed plate 3a fixed mounting is in 2 upper ends of support column and with 2 axis collineations of support column, a plurality of guide bars 3b around fixed plate 3a axis and fixed plate 3a clearance fit, 4 axes and the spherical surface of spherical surface buffering subassembly are cushioned 4 bottom fixed connection around the spherical surface at the guide bar 3b top, the guide bar 3b bottom is equipped with the stopper that prevents guide bar 3b and break away from on fixed plate 3a, damping spring 3c cover is established on guide bar 3b and is between fixed plate 3a and spherical surface buffering subassembly 4.
When the vibration occurs, the external cylinder 1 is influenced by longitudinal waves and is subjected to vertical acting force along with the ground, the supporting column 2 moves along with the external cylinder 1, so that the fixing plate 3a is jacked to the spherical buffering component 4 along the axis direction of the guide rod 3b, the damping spring 3c is compressed in the process, the energy of the longitudinal waves is absorbed, and the spherical buffering component 4 on the upper portion of the longitudinal buffering component 3, the top plate 7 and a house are buffered in the vertical direction. In order to deal with the corrosion of the ground bottom environment, the guide rod 3b and the damping spring 3c are subjected to rust prevention treatment.

When the lower cambered plate 4a vibrates with the ground along with the longitudinal buffer component 3, the support column 2 and the outer cylinder 1, the lower cambered plate 4a still has a tendency of keeping a vertical direction due to the gravity action of the top plate 7 above the lower cambered plate and the house, and the house can continuously keep the tendency through the sliding action between the interfaces of the lower cambered plate 4a and the upper cambered plate 4b without vibrating with the ground at the same frequency. Sliding friction between the lower cambered plate 4a and the upper cambered plate 4b is converted into rolling friction through the structure of the ball 4c and the spherical groove at the bottom of the lower cambered plate 4a, the degree of freedom of the lower cambered plate 4a relative to the upper cambered plate 4b is higher, the trend that the top plate 7 and the house keep vertically downward is effectively kept, and the house vibration is smaller.

The small-diameter ring 6a mainly reduces the relative displacement in the lateral direction of the outer cylinder 1 and the top plate 7, and absorbs the energy of the transverse wave. The large-diameter ring 6b mainly reduces the vertical relative displacement between the outer cylinder 1 and the top plate 7, and absorbs the energy of longitudinal waves.

The buffer rope 8c is a rope structure with good toughness and strength, and the upper part of the spherical buffer component 4 and the top plate 7 above the spherical buffer component provide earthquake resisting force through the fixing action of the third hinge lug 8a and the fourth hinge lug 8 b.
