Description

Technical Field

[0001] The invention relates to the field of engineering vibration reduction and seismic isolation, and in particular to a highly sensitive and highly durable vibration reduction and seismic isolation support and its application. Background Art

[0002] Seismic isolation (vibration) technology has been applied to a certain extent in engineering fields such as construction, electricity, precision instruments and transportation, and has achieved relatively satisfactory results. With the continuous development of urbanization, the above fields are gradually developing towards scale, density and complexity, which will face more new problems. The current seismic isolation (vibration) technology is mainly aimed at earthquakes, wind vibrations and impact vibrations, which have large responses and may cause damage or destruction to the project. However, with the further development of urbanization, the project is facing more problems caused by micro-seismic (vibration). Micro-seismic (vibration) mainly includes micro-seismic (vibration) such as micro-earthquakes, traffic vibrations and mechanical vibrations. Its characteristics are small response and high frequency of occurrence. Although micro-seismic (vibration) will not cause obvious damage or destruction to the project, it will affect people's daily production and life and the normal use of precision instruments. Current shock (vibration) control technologies, such as rubber shock (vibration) isolation bearings, steel spring shock (vibration) isolation bearings, viscous dampers, friction dampers and inertia vessels, all require a large input shock (vibration) response to produce deformation and thus exert a shock (vibration) control effect. However, they do not produce obvious deformation when faced with micro-seismic (vibration), so the shock (vibration) control effect is not obvious. At the same time, since micro-seismic (vibration) occurs frequently, the durability requirements of shock (vibration) control devices are also high.

[0003] To sum up, the existing seismic (vibration) control technology cannot exert a more obvious seismic (vibration) isolation effect or energy dissipation effect when facing micro-seismic (vibration). Therefore, there is an urgent need to develop a new type of seismic (vibration) isolation (vibration) bearing that can also play a seismic (vibration) control role under small responses and has high durability.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Embodiment 1

[0041] like Figure 1-Figure 8 A highly sensitive and durable vibration-damping and seismic-isolating bearing shown includes: a base 1, a movable seat 2 and a vertical shear energy-absorbing component 3.

[0042] Among them, one end of the vertical shear energy absorbing component 3 is in contact with the base 1, and the other end is in contact with the movable seat 2, and the base 1 and the movable seat 2 are separated by the vertical shear energy absorbing component 3. The vertical shear energy absorbing component 3 includes a plurality of energy absorbing rings stacked vertically. The energy absorbing ring includes a side sliding ring, which has two inclined surfaces symmetrical up and down, and the two inclined surfaces form an arch at the junction; each of the two inclined surfaces is in contact with a sliding ring 32, and the sliding ring 32 has an inclined surface that matches the inclination of the inclined surface of the side sliding ring, and the sliding ring 32 is fitted with the side sliding ring through the inclined surface, and a rubber layer 33 is fixed between the inclined surfaces of the sliding ring 32 and the inclined surfaces of the side sliding ring. The upper and lower sliding rings 32 do not contact each other, and the two sliding rings 32 both protrude from the upper and lower surfaces of the side sliding ring; between two adjacent energy absorbing rings, the sliding rings 32 are in contact with each other.

[0043] In this embodiment, Figure 3 and Figure 4 As shown, there are two side slip rings, which are divided into an outer slip ring 311 and an inner slip ring 312. The outer slip ring 311 and the inner slip ring 312 are provided with inclined surfaces on the opposite sides. The slip ring 32 abuts between the outer slip ring 311 and the inner slip ring 312. The two sides of the slip ring 32 corresponding to the outer slip ring 311 and the inner slip ring 312 are provided with inclined surfaces, so that the cross section of the slip ring 32 is an isosceles trapezoid. The rubber layer 33 is bonded to the side slip ring by vulcanization. Preferably, the side slip ring and the slip ring are both steel rings.

[0044] The base 1 includes a bottom plate 11 and a sleeve fixed together. The bottom plate 11 is fixedly installed on the ground. An active cavity 14 is arranged in the sleeve. The sleeve includes an upper sleeve 12 and a lower sleeve 13. The upper sleeve 12 and the lower sleeve 13 are connected by threads. The shaft of the upper sleeve 12 is provided with a socket 15 connected with the active cavity 14. The bottom shaft of the lower sleeve 13 is provided with a receiving groove 16. The diameters of the socket 15 and the receiving groove 16 are both smaller than the inner diameter of the active cavity 14. The lower sleeve 13 is fixedly connected with the bottom plate 11 by bolts; the bottom of the upper sleeve 12 and the bottom of the active cavity 14 are spaced apart.

[0045] The movable seat 2 includes a top plate 21 and a vertical fixing rod 22 fixed together, and the vertical fixing rod 22 is fixedly connected to the top plate 21 by bolts. The vertical fixing rod 22 is T-shaped, and an upper stopper 23 and a lower stopper 24 with an increased diameter are fixed at the upper and lower ends of the vertical rod of the vertical fixing rod 22. The lower stopper 24 can be a nut, which is installed on the vertical fixing rod 22 by threading. The vertical rod of the vertical fixing rod 22 is inserted into the movable cavity 14 from the socket 15, and the upper stopper 23 is located in the socket 15, and the lower stopper 24 is located in the receiving groove 16. The receiving groove 16 has a depth, and the depth satisfies the distance that the lower stopper 24 moves up and down in the receiving groove 16. A pressure-bearing pad 4 is disposed below the upper stopper 23 and above the lower stopper 24. The inner diameters of the two pressure-bearing pads 4 are the same. The outer diameter of the upper pressure-bearing pad 4 matches the inner diameter of the upper sleeve 12, and the outer diameter of the lower pressure-bearing pad 4 matches the inner diameter of the lower sleeve 13. The thickness of the lower pressure-bearing pad 4 is smaller than the interval between the bottom of the upper sleeve 12 and the bottom of the active cavity 14. Combined with the diameters of the socket 15 and the accommodating groove 16, it can be ensured that the pressure-bearing pad 4 is always limited in the active cavity 14.

[0046] The vertical shear energy absorbing member 3 is installed on the vertical fixing rod 22 between the upper and lower pressure-bearing pads 4 , and the vertical shear energy absorbing member 3 is abutted against the two pressure-bearing pads 4 .

[0047] During assembly, firstly, the vertical fixing rod 22 is matched with the upper sleeve 12, the vertical shear energy absorbing member 3, and the pressure-bearing gasket, and then the lower stopper 24 (nut) is screwed with the vertical fixing rod 22 through threads, and finally the lower sleeve 13 is screwed with the upper sleeve 12 through threads to realize the assembly of the entire support. Thus, the vertical fixing rod 22 and the pressure-bearing gasket work together, so that when the vertical fixing rod 22 moves up and down, the vertical shear energy absorbing member 3 is in a compressed state.

[0048] like Figure 5 and Figure 6As shown, when the support is subjected to vertical pressure during microseismic (vibration) process, the top plate 21 will drive the vertical fixed rod 22 to move downward, and then cooperate with the upper pressure-bearing gasket to put the vertical shear energy-absorbing component 3 in a downward pressure state, wherein the upper sliding ring 32 in the top energy-absorbing ring moves vertically downward, so that the rubber layer 33 in contact on both sides is squeezed and sheared, and then the squeezing force is transmitted to the outer sliding ring 311 and the inner sliding ring 312, and the outer sliding ring 311 and the inner sliding ring 312 continue to transmit the squeezing force downward to make the rubber layer 33 on the lower slope squeezed and sheared, and then continue to transmit it to the lower sliding ring 32, and then transmit it to the upper sliding ring 32 in the next energy-absorbing ring through the lower sliding ring 32, and then repeat the above process. In the above process, the vertical shear energy-absorbing component 3 can produce a significant seismic isolation effect, and the rubber layer 33 will produce an energy-absorbing effect during the squeezing and shearing process. At the same time, the vertical shear energy-absorbing component 3 as a whole will produce a vertical upward reaction force, providing self-resetting ability, and can also provide upward support force.

[0049] like Figure 7 and Figure 8 As shown, when the support is subjected to vertical tension during microseismic (vibration) process, the top plate 21 will drive the vertical fixed rod 22 to move upward, and cooperate with the lower pressure gasket to put the vertical shear energy-absorbing component 3 in an upward pressure state, wherein the lower sliding block in the bottom energy-absorbing ring moves vertically upward, so that the rubber layer 33 in contact on both sides is squeezed and sheared, and then the squeezing force is transmitted to the outer sliding ring 311 and the inner sliding ring 312, and the outer sliding ring 311 and the inner sliding ring 312 continue to transmit the squeezing force upward to make the rubber layer 33 on the upper inclined surface squeezed and sheared, and then continue to transmit it to the upper sliding ring 32, and then transmit it to the lower sliding ring 32 in the upper energy-absorbing ring through the upper sliding ring 32, and then repeat the above process. In the above process, the vertical shear energy-absorbing component 3 can produce a significant seismic isolation effect, and the rubber layer 33 will produce an energy-absorbing effect during the squeezing and shearing process. At the same time, the vertical shear energy-absorbing component 3 as a whole will produce a vertical downward reaction force, providing self-resetting capability.

[0050] This embodiment is preferred because the application engineering objects are characterized by large scale, density and complexity. This form has large bearing capacity, strong microseismic (vibration) isolation ability, strong energy dissipation ability, large recovery force and small deformation, and ordinary technicians in the relevant technical field can flexibly design it according to the actual needs of different building types.

[0051] Embodiment 2

[0052] like Figure 9-10 As shown, the difference from the first embodiment is that there is only one side sliding ring 31, the sliding ring 32 is located inside the side sliding ring, and the outer side surface of the sliding ring 32 is an inclined surface, so that the cross section of the sliding ring 32 is a right-angle trapezoid. In this way, the support as a whole has a lower cost and a greater deformation capacity.

[0053] Embodiment 3

[0054] like Fig.11 and Fig.12 As shown, the difference from the second embodiment is that the rubber layer 33 is bonded to the surface of the sliding ring 32 by vulcanization. This method can also achieve lower costs and greater deformation capacity.

[0055] Embodiment 4:

[0056] like Fig.13 and Fig.14 As shown, the difference from the first embodiment is that the rubber layer 33 is bonded to the surface of the sliding ring 32 by vulcanization, and such a design can only pursue lower costs.

[0057] Embodiment 5

[0058] When the number of the energy dissipation rings is 1-5, the vibration-damping and seismic isolation bearing is used in seismic isolation engineering. When the number of the energy dissipation rings is 6 or more, the vibration-damping and seismic isolation bearing is used as an energy dissipation damper in energy dissipation and vibration reduction engineering, such as Fig.15 shown.

[0059] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
