Description

Technical Field

[0001] This invention belongs to the field of bridge engineering technology, and relates to bridge bearings, specifically to a noise reduction and vibration damping multi-directional sliding tension-compression bearing and its assembly method. Background Technology

[0002] Tension-compression bearings can withstand both compressive and tensile forces simultaneously, and are commonly used for end bearings of suspension bridges, continuous beam bridges with small side spans, and steel beam bridges with light self-weight, as well as transition pier bearings of cable-stayed bridges. Currently, commonly used tension-compression bearings for bridges in general areas mainly include those with separate bearing and tension rod installations, those with vertical locking plates between the top and bottom plates, and those with vertical locking plates and bolts between the top plate, intermediate spherical shell, and bottom plate. In seismic zones, commonly used damping tension-compression bearings are those that incorporate shear pins into general area tension-compression bearings. Under seismic action, the shear pins break, allowing for multi-directional movement, or they utilize the shear deformation of high-damping bodies, such as high-damping rubber materials, to adapt to multi-directional deformation. However, they have the following shortcomings:

[0003] 1) As vehicles travel on the bridge deck, the tension and compression bearings undergo vertical pressure and tension conversion. The vertical assembly gaps between the bearing components generate significant noise during the opening and closing process, which cannot meet the low-noise environmental protection requirements of environmentally sensitive areas.

[0004] 2) Cannot simultaneously meet the requirements of vibration reduction and multi-directional movement of bridge tension-compression bearings in seismic zones, such as tension-compression bearings with shear pins; or although the bearing can move slightly in the horizontal direction by utilizing the lateral deformation of the bearing, the amount of movement is very small due to the control of the bearing's compressive stability, and it is not a true multi-directional movement, such as high-damping rubber bearings.

[0005] 3) The support structure is complex, which is not conducive to manufacturing and maintenance. Summary of the Invention

[0029] Compared with the prior art, the present invention has the following advantages:

[0030] (1) The tension and compression bearing provided by the present invention adopts a suitable pre-force structure such as an intermediate spherical shell and vertical locking. By applying pre-force, it ensures that each component of the bearing is always in a compressed state under the action of alternating tension and compression forces, and no separation gaps appear among the components of the bearing. This eliminates the noise generated by the opening and closing of the separation gaps of the bearing components during vehicle operation.

[0031] (2) The tension and compression bearing provided by the present invention is connected by mutual pre-force between the bearing top plate, the intermediate spherical shell and the bearing bottom plate, which effectively ensures that the bearing can withstand alternating tension and compression forces. The bearing rotates through the arc surface between the intermediate spherical shell and the bearing bottom plate and the anchor spherical crown plate. The horizontal distance between the bearing top plate and the intermediate spherical shell effectively ensures horizontal multi-directional movement, which is safe and reliable.

[0032] (3) The frame-shaped damping body, external damping body and column-shaped damping body of the tension and compression bearing provided by the present invention not only meet the needs of vibration reduction and energy consumption, but also meet the needs of applying pre-force to press the bearing components.

[0057] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0058] A noise reduction and vibration damping multi-directional sliding tension-compression support, such as Figures 1-6 As shown, the support includes a base plate 1, a top plate 2, a vertical locking plate 3, a central spherical shell 4, and an anchored spherical crown plate 5. A base plate anchor rod 111 is centrally located on the base plate 1. The central spherical shell 4 is fitted onto the base plate anchor rod 111 and slidably connected to the base plate 1.

A columnar damping body 7 is provided between the base plate anchor rod 111 and the top plate 2. An external damping body 666 is installed between the base plate 1 and the vertical locking plate 3.

[0059] In some preferred embodiments of the present invention, the base plate anchor rod 111 is cylindrical with an external thread at its top; the support base plate 1 is stepped downwards from the base plate anchor rod 111 as the center; the uppermost stepped surface of the support base plate 1 facing the base plate anchor rod 111 is recessed downwards to form a first concave arc surface, and a base plate slide plate 102 is adhered to the first concave arc surface. The intermediate spherical shell 4 has a centrally located central spherical shell core hole 403, which is fitted onto the base plate anchor rod 111. The intermediate spherical shell 4 has a second concave arc surface that matches the first concave arc surface of the support base plate 1. The second concave arc surface is slidably connected to the base plate slide plate 102 adhered to the first concave arc surface of the support base plate 1, thereby allowing the intermediate spherical shell 4 to be slidably connected to the support base plate 1. This connection shape makes the structure compact and facilitates manufacturing and installation.

[0060] In some preferred embodiments of the present invention, the anchored spherical crown plate 5 has an anchored spherical crown plate core hole 511 inside, and the inner side of the anchored spherical crown plate core hole 511 is provided with an internal thread that matches the external thread at the top of the bottom plate anchor rod 111, so that the anchored spherical crown plate 5 is threadedly connected to the bottom plate anchor rod 111; the anchored spherical crown plate 5 has an arc-shaped surface that gradually decreases outward on the side facing the middle spherical shell 4, and the middle spherical shell 4 has a third concave arc-shaped surface that matches the arc-shaped surface of the anchored spherical crown plate 5, and a middle spherical shell core slide plate 401 is attached to the third concave arc-shaped surface, and the middle spherical shell 4 is slidably connected to the anchored spherical crown plate 5 through the middle spherical shell core slide plate 401.

[0061] In some preferred embodiments of the present invention, the bottom of the cylindrical damping body 7 is provided with a circular groove that matches the top of the bottom plate anchor rod 111. The cylindrical damping body 7 is sleeved on the upper part of the bottom plate anchor rod 111 and the end of the circular groove is in close contact with the anchor spherical crown plate 5. The cylindrical damping body 7 is adhered to the anchor spherical crown plate 5 and the bottom plate anchor rod 111. The upper end of the cylindrical damping body 7 is inserted into a groove provided on the lower surface of the support top plate 2 and the position and upper surface size of the cylindrical damping body 7 match the groove, which is a snap-fit ​​connection.

[0062] In some preferred embodiments of the present invention, the vertical locking plate 3 is connected to the support top plate 2 by clamping bolts 8, and a vertical locking plate slide plate 302 is attached to the side of the vertical locking plate 3 facing the support top plate 2. The intermediate spherical shell 4 is slidably connected to the vertical locking plate 3 through the vertical locking plate slide plate 302. The lower end of the frame-shaped damping body 6 is attached to the intermediate spherical shell 4, and the upper end is inserted into a groove provided on the lower surface of the support top plate 2 and matching the position and upper surface size of the frame-shaped damping body 6, which is a snap-fit ​​connection. A middle spherical shell top slide plate 402 is attached to the top of the intermediate spherical shell 4 facing the support top plate 2, and the intermediate spherical shell 4 is slidably connected to the support top plate 2 through the middle spherical shell top slide plate 402.

[0063] In some preferred embodiments of the present invention, the two ends of the external damping body 666 are respectively glued or snapped to the support base plate 1 and the vertical locking plate 3.

[0064] In this invention, the support base plate 1, support top plate 2, vertical locking plate 3, intermediate spherical shell 4, anchoring spherical crown plate 5, and clamping bolt 8 can be made of steel structural materials; the frame-shaped damping body 6, column-shaped damping body 7, and external damping body 666 can all be made of metal or organic polymer materials; the base plate sliding plate 102, locking plate sliding plate 302, intermediate spherical shell core sliding plate 401, and intermediate spherical shell top sliding plate 402 can be made of organic polymer materials.

[0065] Based on the above, the key structure of the present invention is as follows: (1) Steel components: support base plate 1, support top plate 2, intermediate spherical shell 4, and anchored spherical crown plate 5, vertical locking plate 3, which constitute the main bearing structure of the support and are used for locking preload. The preload can ensure that the components of the support are always pressed together under tension and pressure without separation gaps, thus avoiding noise caused by the opening and closing of separation gaps. (2) Polymer sliding plate components: base plate sliding plate 102, vertical locking plate sliding plate 302, intermediate spherical shell core sliding plate 401, and intermediate spherical shell top sliding plate 402, which avoid direct friction between steel and reduce frictional resistance. (3) Damping body: frame-shaped damping body 6, column-shaped damping body 7, and external damping body 666 are energy-consuming elements. During the preload application stage, the frame-shaped damping body 6 and column-shaped damping body 7 also play the role of locking the preload between the support top plate 2, anchored spherical crown plate 5 and vertical locking plate 3. The frame-shaped damper 6, the column-shaped damper 7, and the external damper 666 absorb and dissipate the impact energy generated by earthquakes and vehicles through their own deformation.

[0066] It should be noted that all components are assembled vertically perpendicular to the horizontal plane to ensure reasonable stress distribution on the support.

[0067] Assuming the maximum of the pressure and tension forces borne by the noise-reducing and vibration-damping multi-directional sliding tension-compression bearing of this invention is P, the heights of the frame-shaped damping body 6 and the cylindrical damping body 7 are Hk and Hz, respectively, and the sum of their areas is A. The values ​​of Hk and Hz are determined based on the displacement value of the bearing's horizontal deformation and the magnitude of the vertical compression of the damping body caused by the pre-force. The vertical compression of the pre-force damping body, with the top surface of the intermediate spherical shell 4 being 0.85 times shorter than Hk, ensures the support of the intermediate spherical shell 4 for the bearing top plate 2 in the compressed state. The cylindrical damping body 7 further compresses the anchor spherical crown plate 5 and the intermediate spherical shell 4. The net distance between the vertical locking plate 3 and the bearing top plate 2 is matched accordingly with Hk and Hz. The value of A is determined based on the energy dissipation requirements of vibration damping. A pre-force of 1.2 times P is applied between the bearing bottom plate 1 with the attached sliding plate and the intermediate spherical shell 4 with the attached sliding plate. After applying a preload of 1.2 times P, the possible tension between the connections during operation does not exceed the preload, ensuring that the connections will not separate or close. The anchor spherical crown plate 5 and the base plate anchor rod 111 are tightened using a torsion manipulator, completing the preload assembly of the support base plate 1 and the intermediate spherical shell 4. The frame-shaped damping body 6, whose height includes the compression calculated according to the preload of 1.2 times P, is attached to the intermediate spherical shell 4. The cylindrical damping body 7 is attached to the top surface of the anchor spherical crown plate 5 and the base plate anchor rod 111, respectively. The support top plate 2 is then covered, a preload of 1.2 times P is applied, and the vertical locking plate 3 with the attached sliding plate is connected with clamping bolts 8 and tightened, completing the preload assembly of the support top plate 2 and the intermediate spherical shell 4. An external damper 666 is installed between the bearing base plate 1 and the vertical locking plate 3. The external damper 666 can restrain the vertical displacement of the vertical locking plate 3 and play an energy dissipation role when the vertical locking plate 3 deforms horizontally, while also providing sealing and dust protection for the bearing. Pre-stressing ensures that all components of the bearing are always in a compressed state under tension and compression, without any separation gaps, thus avoiding noise caused by the opening and closing of separation gaps during vehicle operation. The horizontal distance between the bearing top plate 2 and the intermediate spherical shell 4 accommodates the multi-directional movement of the bearing. The distance between the core hole 403 of the intermediate spherical shell and the outer edge of the anchor rod 111 of the base plate accommodates the rotation of the bearing. The frame-shaped damper 6, the external damper 666, and the cylindrical damper 7 meet the needs of vibration reduction and energy dissipation.
