Description

Technical Field

[0001] The present invention relates to the technical field of seismic isolation of civil engineering structures and vertical vibration isolation of rail transit, specifically a disc spring rubber three-dimensional vibration dual-control bearing and an installation process. The bearing is particularly suitable for scenarios where it is necessary to simultaneously isolate the horizontal force of an earthquake and reduce the vertical vibration of the structure, such as the integrated vibration-seismic control of rail transit on subway covers or buildings along the line, vibration reduction and isolation of the base of precision instruments and equipment, and earthquake-vehicle vibration coupling protection of bridge structures. Background Art

[0002] In the fields of construction, bridge engineering, and large-scale storage tank engineering, structures face threats not only from earthquakes but also from environmental vibrations (such as traffic and equipment vibrations). Vibration can cause structural fatigue damage, impacting the service life of the structure, the normal operation of internal equipment, and affecting comfort. Seismic action can directly threaten structural safety, resulting in serious casualties and property damage.

[0003] At present, commonly used seismic isolation bearings, such as rubber bearings, mainly focus on controlling horizontal earthquake effects, dissipating earthquake energy through the flexible deformation of rubber, but have poor control effects on vertical vibrations. Common vibration reduction devices, such as spring dampers, although they have certain effects in vibration reduction, are difficult to effectively cope with the huge horizontal forces generated by earthquakes. In actual engineering, there are relatively few devices that consider both vibration control and earthquake effect control. The core components of existing similar products for vertical vibration control have low vertical stiffness, weak horizontal shear resistance and tensile and compressive resistance caused by additional bending moments, and require additional shear, tensile and compressive components. Existing products either use thick round steel sleeves or thick steel plates. The disadvantages are that the products are difficult to process, time-consuming, costly, heavy, and bulky in appearance, making them difficult to popularize. Therefore, there is an urgent need to develop a device that can effectively reduce earthquake effects and vibrations at the same time based on actual force characteristics, with ingenious design, simple processing, low cost, light weight, and lightweight appearance, so as to improve the safety, economy and other comprehensive performance of the structure. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems of comprehensive performance such as safety and economy of the supports in the prior art, thereby proposing a disc spring rubber three-dimensional vibration dual-control support and its installation process.

[0005] In order to achieve the above-mentioned objectives, the present invention adopts the following technical solutions: a disc spring rubber three-dimensional vibration dual-control bearing, comprising an upper disc spring bearing and a lower rubber bearing, the upper disc spring bearing comprising an upper flange plate, connecting bolts, a force transmission member, a tensile plate, a force transmission plate, an outer guide tube, a disc spring group, a stiffening rib, a pull rod, an upper nut and a lower nut, the lower rubber bearing comprising a middle flange plate, a lower flange plate, a skeleton plate, rubber, and a process hole, the upper disc spring bearing is connected to the lower rubber bearing by a pull rod and welding, the disc spring bearing is formed by overlapping or matching multiple groups of disc spring groups, its vertical stiffness is small, and it effectively absorbs and dissipates the vertical vibration energy of the structure through elastic deformation; the rubber bearing is formed by vulcanizing and bonding rubber and steel plates, its horizontal stiffness is small, and it isolates the horizontal seismic force through shear deformation, and the two are coupled through a rigid connecting plate to form a two-way decoupling control mechanism of vertical vibration reduction and horizontal seismic isolation.

[0006] Further preferably, the outer guide tube adopts a group of round tubes or square tubes connected in series with the lower rubber support, and can also adopt more than one group of round tubes or square tubes connected in parallel with the lower rubber support.

[0007] Further preferably, the disc spring support is formed by overlapping or matching multiple groups of disc springs, and its vertical stiffness is small. It effectively absorbs and dissipates the vertical vibration energy of the structure through elastic deformation. The outer guide tube can ensure that the disc spring group is under axial pressure and is easy to install. The outer guide tube can be a round tube or a square tube, etc., and a certain gap is left between it and the disc spring group, but the single-side gap is generally not more than 0.8mm to ensure the vertical stability of the disc spring group. The force transmission member, the force transmission plate and the upper flange plate are formed as a whole through the connecting bolts to ensure that the vertical force of the upper structure can be evenly transmitted to the disc spring group. The tensile plate leaves a certain gap with the outer guide tube, and the tensile plate is placed under the force transmission member. The stiffening ribs are evenly arranged around the outer guide tube and are connected to the outer guide tube and the middle flange plate by welding. The upper flange plate is connected to the middle flange plate through a pull rod.

[0008] Further preferably, the lower rubber support is formed by vulcanizing and bonding the rubber to the skeleton plate, the upper flange plate, and the middle flange plate, and has a small horizontal stiffness, and isolates the horizontal force of earthquakes through shear deformation.

[0009] Further preferably, the upper flange plate is connected to the middle flange plate through a pull rod, and the disc spring group can be pre-stressed and then the lower nut is tightened to reduce the deformation difference of the disc spring rubber three-dimensional vibration dual-control support before and after construction. After the upper structure construction is completed, the upper nut is screwed to a position about 5 mm above the middle flange plate. This can not only ensure the free up and down vibration of the disc spring rubber three-dimensional vibration dual-control support, but also greatly improve the force of the large deformation lower pull rod and flange plate. The corners of the upper flange plate are provided with bolt holes for connecting bolts, sleeves and anchoring steel bars to form a whole with the structural column. A plurality of groups of countersunk holes are symmetrically arranged around the upper flange plate. The pull rod passes through the countersunk holes of the upper flange plate and the bolt holes of the middle flange plate, and is connected together through the lower nut and the upper nut. A plurality of groups of countersunk holes are symmetrically arranged in the middle of the upper flange plate, and the connecting bolts pass through the countersunk holes to be connected to the force transmission member.

[0010] Further preferably, a plurality of groups of screw holes are symmetrically arranged in the middle of the force transmission member, which is connected to the upper flange plate and the force transmission plate by bolts. The height of the force transmission member is not less than the sum of the total pressure and displacement of the disc spring group and the thickness of the tensile plate.

[0011] Further preferably, a hole is dug in the middle of the tensile plate with a gap of 1mm from the outer dimension of the force transmission member. The outer dimension of the tensile plate is 5mm larger on one side than the outer guide tube, which facilitates welding the tensile plate and the outer guide tube. The force transmission plate is located below the tensile plate and can withstand tension, transmit bending moment and shear force.

[0012] Further preferably, the inner diameter of the outer guide tube is slightly larger than the outer diameter of the disc spring group, but the single-side gap is generally not greater than 0.8 mm to ensure the vertical stability of the disc spring group. The stiffening ribs are evenly arranged around the outer guide tube and are connected to the outer guide tube and the middle flange plate by welding to ensure that the outer guide tube can withstand shear force, tension and bending moment. The stiffening ribs can be in the form of triangles or the like.

[0013] Further preferably, multiple groups of bolt holes are symmetrically arranged around the middle flange plate, the pull rod passes through the countersunk holes of the upper flange plate and the bolt holes of the middle flange plate, and is connected together by the lower nut and the upper nut. There is a process hole in the middle of the middle flange plate, which can be used to position the skeleton plate or fill the lead core during the production process of the lower rubber bearing to enhance the horizontal bearing capacity such as wind resistance of the disc spring rubber three-dimensional vibration dual-control bearing.

[0014] Further preferably, the rubber of the lower rubber support is formed by vulcanization bonding with the skeleton plate, the middle flange plate and the lower flange plate, and has low horizontal stiffness, and isolates the horizontal force of earthquakes through shear deformation.

[0015] Further preferably, the upper disc spring support also includes a torsion-resistant baffle and a guide hole, and the lower rubber support also includes a lower flange plate. The upper part of the torsion-resistant baffle is fixedly connected to the upper flange plate by bolts or welding, and the lower part of the torsion-resistant baffle is connected to the middle flange plate through the guide hole and bolts. The width of the guide hole is smaller than the bolt head diameter and larger than the effective diameter of the bolt. The length of the guide hole is greater than the total pressure and displacement of the disc spring group, ensuring that the upper disc spring support can move freely up and down under the action of vertical earthquakes and vertical vibrations. The torsion-resistant baffle can provide torsional and shear bearing capacity for the support.

[0016] A process for installing a disc spring rubber three-dimensional vibration dual-control bearing includes the following steps:

[0017] Step 1: Combining the middle flange plate, the lower flange plate, the frame plate, and the rubber into a rubber bearing through a vulcanization process;

[0018] Step 2: Weld the outer guide tube to the middle flange plate in the center, and then symmetrically weld the stiffening ribs to the outer guide tube and the middle flange plate;

[0019] Step 3: Place the disc spring assembly into the outer guide tube;

[0020] Step 4: Connect the force transmission plate and the force transmission member with bolts, and place the force transmission plate above the disc spring assembly;

[0021] Step 5: Place the tensile plate through the force transmission member;

[0022] Step 6: Connect the upper flange plate to the force transmission member through bolts;

[0023] Step 7: Pass the tie rod through the countersunk holes around the upper flange plate, pass the upper nut sleeve through the tie rod, and pass the tie rod through the bolt holes around the middle flange plate;

[0024] Step 8: Using a pre-compression process, first compress the upper flange plate and the disc spring assembly downward by a certain displacement, then tighten the lower nut against the bottom of the middle flange plate, and finally weld the outer guide steel pipe to the tensile plate;

[0025] Step 9: The upper portion of the anti-torsion baffle is fixed to the upper flange plate by bolts or welding, and the lower portion of the anti-torsion baffle is connected to the middle flange plate through the guide holes and bolts, thereby completing the assembly of the integral disc spring rubber three-dimensional vibration dual-control support;

[0026] Step 10: After the construction of the upper structure is completed, tighten the upper nut to a position 5 mm above the middle flange plate, and further tighten the lower nut against the bottom of the middle flange plate. This completes the installation of the disc spring rubber three-dimensional vibration dual-control support.

[0027] The beneficial effects of the present invention are: the advantage is that a pull rod design is adopted between the upper flange plate and the middle flange plate, which cleverly solves the shear and tensile stress problems of the upper rail transit vibration core components (such as coil springs, disc springs, rubber, etc.). At the same time, the design has the characteristics of simple processing, low cost, light weight and light appearance. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0047] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0048] Example 1

[0049] Reference Figure 1-18 , a disc spring rubber three-dimensional vibration dual-control bearing, including an upper disc spring bearing and a lower rubber bearing, the upper disc spring bearing includes an upper flange plate 1, a connecting bolt 3, a force transmission member 2, a tensile plate 4, a force transmission plate 5, an outer guide tube 7, a disc spring group 6, a stiffening rib, a pull rod 8, an anti-torsion baffle 17, a guide hole 18, an upper nut 10 and a lower nut 12, the lower rubber bearing includes a middle flange plate 11, a lower flange plate 15, a skeleton plate 13, a rubber 14, a process hole 16, the upper disc spring support is connected to the lower rubber support by a pull rod 8. The disc spring support is composed of multiple disc spring groups 6 stacked or matched, and has low vertical stiffness. It effectively absorbs and dissipates the vertical vibration energy of the structure through elastic deformation. The rubber support is formed by vulcanizing and bonding rubber 14 and steel plate. It has low horizontal stiffness and isolates the horizontal force of earthquake through shear deformation. The two are coupled by a rigid connecting plate to form a two-way decoupling control mechanism for vertical vibration reduction and horizontal seismic isolation.

[0050] The disc spring support is composed of multiple disc spring groups 6 stacked or matched. Its vertical stiffness is small, and it effectively absorbs and dissipates the vertical vibration energy of the structure through elastic deformation. The outer guide tube 7 can ensure that the disc spring group 6 is under axial pressure and is easy to install. The outer guide tube 7 can be a group of round tubes or a group of square tubes, etc., or multiple groups of round tubes or multiple groups of square tubes, etc. There is a certain gap between the disc spring group 6, but the single-side gap is generally not more than 0.8mm to ensure the vertical stability of the disc spring group 6. The spring group 6 can be connected in series or in parallel. The force transmission member 2, the force transmission plate 5 and the upper flange plate 1 are integrated by connecting bolts 3 to ensure that the vertical force of the upper structure can be evenly transmitted to the disc spring group 6. The tension plate 4 and the outer guide tube 7 are connected as a whole by welding. The force transmission plate 5 is placed below the tension plate 4. The stiffening ribs 9 are evenly arranged around the outer guide tube 7 and are connected to the outer guide tube 7 and the middle flange plate 11 by welding. The upper flange plate 1 is connected to the middle flange plate 11 by a tie rod 8.

[0051] The upper part of the anti-torsion baffle 17 is fixed to the upper flange plate 1 by bolts or welding, and the lower part of the anti-torsion baffle 17 is connected to the middle flange plate 11 through the guide hole 18 and bolts. The width of the guide hole 18 is smaller than the diameter of the bolt head and larger than the effective diameter of the bolt. The length of the guide hole 18 is greater than the total compression and displacement of the disc spring group 6, ensuring that the upper disc spring support can move freely up and down under the action of vertical earthquake and vertical vibration. The anti-torsion baffle 17 can provide the support with torsional and shear bearing capacity.

[0052] The lower rubber bearing is formed by vulcanization bonding of the rubber 14 with the frame plate 13, the upper flange plate 1, and the middle flange plate 11. It has low horizontal stiffness and isolates the horizontal force of earthquakes through shear deformation.

[0053] The upper flange plate 1 is connected to the middle flange plate 11 through the tie rod 8. The disc spring group 6 can be pre-stressed and then the lower nut 12 can be tightened to reduce the deformation difference of the disc spring rubber three-dimensional vibration dual-control support before and after construction. After the upper structure construction is completed, the upper nut 10 is screwed to a position about 5 mm above the middle flange plate 11. This can not only ensure the free up and down vibration of the disc spring rubber three-dimensional vibration dual-control support, but also greatly improve the force of the large deformation lower tie rod 8 and the flange plate. There are bolt holes at the corners of the upper flange plate 1 for connecting bolts 3, sleeves and anchor steel bars to form a whole with the structural column. Multiple groups of countersunk holes are symmetrically arranged around the upper flange plate 1. The tie rod 8 passes through the countersunk holes of the upper flange plate 1 and the bolt holes of the middle flange plate 11, and is connected together through the lower nut 12 and the upper nut 10. Multiple groups of countersunk holes are symmetrically arranged in the middle of the upper flange plate 1. The connecting bolts 3 pass through the countersunk holes and are connected to the force transmission member 2;

[0054] Multiple groups of screw holes are symmetrically arranged in the middle of the force transmission member 2, which is connected to the upper flange plate 1 and the force transmission plate 5 by bolts. The height of the force transmission member 2 is not less than the sum of the total pressure and displacement of the disc spring group 6 and the thickness of the tensile plate 4;

[0055] A hole is dug in the middle of the tensile plate 4 with a 1mm gap from the outer dimension of the force transmission member 2. The outer dimension of the tensile plate 4 is about 5mm larger on one side than the outer guide tube 7, which is convenient for welding the tensile plate 4 and the outer guide tube 7. The force transmission plate 5 is located below the tensile plate 4 and can withstand tension, transmit bending moment and shear force.

[0056] The inner diameter of the outer guide tube 7 is slightly larger than the outer diameter of the disc spring group 6, but the single-side gap is no more than 0.8 mm to ensure the vertical stability of the disc spring group 6. The stiffening ribs 9 are evenly arranged around the outer guide tube 7 and connected to the outer guide tube 7 and the middle flange plate 11 by welding to ensure that the outer guide tube 7 can withstand shear force, tension and bending moment. The stiffening ribs 9 can be triangular or other forms.

[0057] Multiple groups of bolt holes are symmetrically arranged around the middle flange plate 11. The tie rod 8 passes through the countersunk hole of the upper flange plate 1 and the bolt hole of the middle flange plate 11, and is connected together by the lower nut 12 and the upper nut 10. There is a process hole 16 in the middle of the middle flange plate 11, which can be used to position the skeleton plate 13 during the production process of the lower rubber bearing or to fill the lead core to enhance the horizontal bearing capacity of the disc spring rubber three-dimensional vibration dual-control bearing such as wind resistance;

[0058] The lower rubber support rubber 14 is formed by vulcanization bonding with the skeleton plate 13, the middle flange plate 11 and the lower flange plate 15. Its horizontal stiffness is small and it isolates the horizontal force of earthquake through shear deformation.

[0060] A process for installing a disc spring rubber three-dimensional vibration dual-control bearing includes the following steps:

[0061] Step 1: Combine the middle flange plate 11, the lower flange plate 15, the frame plate 13, and the rubber 14 into a rubber bearing through a vulcanization process;

[0062] Step 2: Weld the outer guide tube 7 to the middle flange plate 11 in the center, and then weld the stiffening ribs 9 symmetrically to the outer guide tube 7 and the middle flange plate 11;

[0063] Step 3: Place the disc spring assembly 6 into the outer guide tube 7;

[0064] Step 4: Connect the force transmission plate 5 and the force transmission member 2 with bolts, and place the force transmission plate 5 on top of the disc spring group 6;

[0065] Step 5: Place the tensile plate 4 through the force transmission member 2;

[0066] Step 6: Connect the upper flange plate 1 to the force transmission member 2 with bolts;

[0067] Step 7: Pass the tie rod 8 through the countersunk holes around the upper flange plate 1, insert the upper nut 10 through the tie rod 8, and pass the tie rod 8 through the bolt holes around the middle flange plate 11;

[0068] Step 8: Using a pre-compression process, first compress the upper flange plate 1 and the disc spring assembly 6 downward by a certain displacement, then tighten the lower nut 12 against the bottom of the middle flange plate 11, and finally weld the outer guide steel pipe to the tensile plate 4;

[0069] Step 9: The upper portion of the anti-torsion baffle 17 is fixed to the upper flange plate 1 by bolts or welding, and the lower portion of the anti-torsion baffle 17 is connected to the middle flange plate 11 through the guide hole 18 and bolts, thereby completing the assembly of the integral disc spring rubber three-dimensional vibration dual-control support;

[0070] Step 10: After the construction of the upper structure is completed, screw the upper nut 10 to a position 5 mm above the middle flange plate 11, and further tighten the lower nut 12 against the bottom of the middle flange plate 11, thereby completing the installation of the disc spring rubber three-dimensional vibration dual-control support.
