Description

Technical Field

[0001] The present application relates to the fields of bridge engineering and earthquake engineering, and in particular to a bridge plate rubber bearing anti-seismic system that is adaptable to support rotation. Background Art

[0002] The low-cost and reliable plate rubber bearing is one of the most widely used bearing types in small and medium span bridge projects. The main function of this type of bearing is to transfer the load of the upper structure such as the main beam to the lower structure of the bridge, and rely on the shear deformation of the rubber layer to adapt to the deformation of the main beam caused by factors such as temperature. Under the action of an earthquake, the flexible shear deformation of the plate rubber bearing can also effectively disperse the seismic inertia force and play a certain role in seismic isolation. In order to give full play to the horizontal shear deformation of the plate rubber bearing, the upper and lower sides of the bearing generally need to be anchored to the main beam and the bridge pier respectively.

[0003] However, the plate rubber bearings of bridges constrained on both sides are prone to more complex stress states. In addition to the compressive stress and shear stress caused by vertical and horizontal loads, the bridge piers will be vibrated during an earthquake and the rubber bearings will be deformed. The bridge will tilt under the action of inertia. At this time, the rubber bearings will also produce large pure bending stresses due to the relative rotation between the piers and the main beams. The superposition of these stresses will significantly increase the risk of bearing failure under strong earthquakes. In addition, the premature failure of the plate rubber bearings also interrupts the transmission path of the earthquake inertial force, resulting in the bearings losing their protection of the bridge before the earthquake ends, resulting in beam fall.

[0004] There is currently no effective solution to the problem that rubber bearings in existing seismic resistance systems are prone to pure bending stress under strong earthquakes, leading to bearing failure. Summary of the invention

[0005] The present invention provides a bridge plate rubber bearing anti-seismic system adaptable to support rotation, so as to solve the problem that the rubber bearing in the existing anti-seismic system is prone to pure bending stress under strong earthquake action, resulting in bearing failure.

[0006] The present invention provides a bridge plate rubber bearing anti-seismic system that is adaptable to support rotation, including a plate rubber bearing, an upper top plate, an arc-shaped slider, a bridge pier and a polytetrafluoroethylene slider. The top of the plate rubber bearing is fixedly connected to the upper top plate, and the upper top plate is used to be connected to the main beam of the bridge. The bottom of the arc-shaped slider is convex downward so that the bottom surface forms a first arc-shaped surface, and the top of the arc-shaped slider is fixedly connected to the bottom of the plate rubber bearing. An arc-shaped slide groove is arranged on the top of the bridge pier, and the groove surface of the arc-shaped slide groove is a second arc-shaped surface. The first arc-shaped surface and the second arc-shaped surface have the same curvature radius and form a surface contact. The arc-shaped surface length of the second arc-shaped surface is greater than the arc-shaped surface length of the first arc-shaped surface. A polytetrafluoroethylene slider is arranged between the first arc-shaped surface and the second arc-shaped surface for the arc-shaped slider to rotate on the arc-shaped slide groove, and the arc-shaped slider can rotate around its own arc center line in the arc-shaped slide groove.

[0007] Furthermore, the shape of the plate rubber bearing is rectangular or circular.

[0008] Furthermore, the arc-shaped slider is a polygonal bottom cylinder, and the polygon is obtained by connecting and combining straight sides of an arc and a trapezoid.

[0009] Furthermore, the arc-shaped slider is a polygonal bottom cylinder, and the polygon is obtained by connecting and combining the straight sides of an arc and a rectangle.

[0010] Furthermore, the two bottom surfaces of the arc-shaped slider are respectively the first side and the second side, the first side and the second side of the arc-shaped slider are symmetrically provided with arc-shaped plate flanges, the first side and the second side of the arc-shaped slider are symmetrically provided with pull-out limit steel plates, the pull-out limit steel plates are vertically covered on the arc-shaped plate flanges and the two ends of the pull-out limit steel plates are fixed to the top of the pier.

[0011] Furthermore, the pull-out limiting steel plate is an arc-shaped curved plate, and the pull-out limiting steel plate and the arc-shaped slide groove have the same curvature radius.

[0012] Furthermore, the arc-shaped plate flange is integrally formed on the arc-shaped slider.

[0013] Furthermore, a plurality of rotation limit blocks are symmetrically arranged on the top of the pier, the rotation limit blocks are symmetrically arranged around the arc-shaped slide groove, and a certain gap is set between the rotation limit blocks and the arc-shaped slide block.

[0014] Furthermore, a polytetrafluoroethylene slide plate is provided between the first arc surface and the second arc surface for the arc slide block to rotate on the arc slide groove.

[0015] The present invention also provides a bridge system, including a bridge plate rubber bearing anti-seismic system adapted to support rotation and a bridge main beam. The bridge plate rubber bearing anti-seismic system adapted to support rotation is the above-mentioned bridge plate rubber bearing anti-seismic system adapted to support rotation. The bridge main beam is installed above the upper top plate in the bridge plate rubber bearing anti-seismic system adapted to support rotation.

[0016] Compared with the related art, the bridge plate rubber bearing anti-seismic system adapted to support rotation provided by the present invention has the following beneficial effects:

[0017] 1. The arc-shaped slider rotates and slides in the arc-shaped slide groove to adapt to the relative rotation between the pier and the main beam, avoiding the plate rubber bearing from generating pure bending stress, thereby achieving the effect of protecting the plate rubber bearing under earthquake action, improving the seismic performance of the plate rubber bearing, providing effective protection for construction and rescue, and solving the problem that the rubber bearing in the existing seismic resistance system is prone to pure bending stress under strong earthquake action, resulting in bearing failure.

[0018] 2. The shape of the pull-out limit steel plate fits the curved plate flange better, and the contact area is larger and the force is more evenly distributed, which is conducive to limiting and protecting the curved plate flange. At the same time, the curved plate flange, the curved slide and the pull-out limit steel plate have the same curvature radius, which is conducive to the sliding of the curved plate flange and prevents jamming.

[0019] 3. Several rotation limit blocks are symmetrically fixed on the top of the bridge pier, and the blocking end of the rotation limit block is set at a set height from the top of the bridge pier. The set height here is set according to the maximum inclination angle of the bridge main beam, that is, even if the plate rubber bearing is deformed and fails, the arc slider will resist the rotation limit block to achieve the final support guarantee and improve safety.

[0020] 4. Under the premise of having the bridge plate rubber bearing seismic system that adapts to support rotation, when the bridge system used is subjected to seismic force, the additional force generated by the relative rotation of the main beam and the pier can be effectively released through the above-mentioned bridge plate rubber bearing seismic system that adapts to support rotation, thereby preventing the plate rubber bearing in the bridge system from generating pure bending stress, thereby increasing the service life of the plate rubber bearing and reducing the risk of bridge beam falling.

[0021] 5. The present invention provides a bridge plate rubber bearing seismic resistance system that adapts to support rotation, which can effectively adapt to the rotation deformation between the bridge main beam and the lower bridge pier, significantly reduce the seismic force demand of the plate rubber bearing caused by the support rotation, and thus reduce the failure risk of the bearing under strong earthquake action. It is of great significance for ensuring a stable seismic inertial force transmission path between the upper and lower structures and reducing the earthquake damage caused by the falling beam of the bridge.

[0022] 6. The plate rubber bearing anti-seismic system provided by the present invention is of great significance for realizing the conventional ductile anti-seismic design concept. The plate rubber bearing system adapted to the bearing rotation can avoid the premature failure of the bearing due to unnecessary pure bending stress under strong earthquake, which is conducive to the continuity and stability of the horizontal shear deformation function of the bearing, thereby ensuring that the lower bridge pier can undergo ductile deformation according to the design expectation, thereby helping engineering designers to better grasp the design results.

[0039] In an embodiment of the present invention, a bridge plate rubber bearing anti-seismic system that adapts to support rotation is provided. Figures 1 to 4 The anti-seismic system of the bridge plate rubber bearing adapted for supporting rotation includes a plate rubber bearing 1, an upper top plate 2, an arc-shaped slider 3, a bridge pier 4, an arc-shaped slide 5, an anti-pulling limit steel plate 6, a rotation limit block 7 and a bolt 8.

[0040] The shape of the plate rubber bearing 1 can be rectangular or circular. In addition, the material of the arc slider 3 can be the same as that of the bridge pier 4, or it can be different from that of the bridge pier 4. The bridge pier 4 can adopt a reinforced concrete structure, or other common structures in the prior art. The polytetrafluoroethylene slide plate is a common material in the prior art, which is often used to reduce the contact friction between materials. The polytetrafluoroethylene slide plate can be an arc plate covering the arc surface of the arc slider 3, or it can be a modular arc plate.

[0041] See also Figure 1The installation method of the bridge plate rubber bearing anti-seismic system adapted to support rotation is as follows: the plate rubber bearing 1 is fixedly connected with an upper top plate 2 on the top, and the upper top plate 2 can be fixed by bolts, expansion bolts, or other commonly used fixing means in the prior art. The upper top plate 2 is used to install the bridge main beam. The top of the upper top plate 2 is in contact with the bottom of the bridge main beam and can be fixed by bolts, or other commonly used fixing means in the prior art.

[0042] The top of the plate rubber bearing 1 can be fixedly connected to the upper top plate 2 by bolts 8, or the top of the plate rubber bearing 1 can be fixedly connected to the upper top plate 2 by vulcanization treatment. The upper top plate 2 is connected to the bridge main beam by bolts 8, or other commonly used fixing means in the prior art. An arc-shaped slide 5 is arranged on the top of the pier 4, and the groove surface of the arc-shaped slide is a second arc-shaped surface. The first arc-shaped surface and the second arc-shaped surface have the same curvature radius and form a surface contact. The arc length of the second arc-shaped surface is greater than the arc length of the first arc-shaped surface. A polytetrafluoroethylene slide plate is arranged between the first arc-shaped surface and the second arc-shaped surface for the arc-shaped slider 3 to rotate on the arc-shaped slide 5. The arc-shaped slider 3 can rotate around its own arc center line in the arc-shaped slide 5.

[0043] See also Figure 2The arc slider 3 is a polygonal bottom cylinder, and the polygon can be obtained by connecting and combining the straight sides of an arch and a trapezoid. However, such an arc slider 3 may not be stable enough when in use, and the rotation distance may be limited. Furthermore, the polygon can also be obtained by connecting and combining the straight sides of an arch and a rectangle. The combination of the arch and the rectangle is a cylinder with a bottom surface, which can keep the arc slider 3 sufficiently stable while also having a sufficient rotation distance with the arc chute 5. The bottom of the arc slider 3 bulges downward so that the bottom surface forms a first arc surface, and the top of the arc slider 3 is fixedly connected to the bottom of the plate rubber bearing 1. The two bottom surfaces of the arc slider 3 are respectively the first side and the second side, and the first side and the second side of the arc slider 3 are symmetrically provided with arc plate flanges, and the first side and the second side of the arc slider 3 are symmetrically provided with pull-out limit steel plates 6, and the pull-out limit steel plates 6 are vertically covered on the arc plate flanges and the two ends of the pull-out limit steel plates 6 are fixed to the top of the pier 4. The two side surfaces perpendicular to the first curved surface on the curved slider 3 protrude outward to form a curved plate flange, and the curved plate flange can also be integrally formed on the curved slider 3. The lower surface of the curved plate flange is flush with the first curved surface, and part of the structure of the pull-out limit steel plate 6 is located in the curved slide groove 5. There is a sliding gap between the pull-out limit steel plate 6 and the second curved surface. The curved plate flange is located in the sliding gap and can slide along the arc direction of the second curved surface. The pull-out limit steel plate 6 is used to limit the curved plate flange. In order to improve the limiting sliding effect of the curved plate flange, the pull-out limit steel plate 6 is set as a curved plate and the pull-out limit steel plate 6 has the same curvature radius as the curved slide groove 5, so that the shape of the pull-out limit steel plate 6 fits the curved plate flange more closely, and the contact area is larger and the force is more uniform, which is conducive to limiting and protecting the curved plate flange. At the same time, the curvature radii of the arc plate flange, the arc chute 5 and the pull-out limit steel plate 6 match each other, which is conducive to the sliding of the arc plate flange and prevents jamming. The two ends of the two pull-out limit steel plates 6 are respectively fixedly connected to the top of the pier 4 to fix the position of the pull-out limit steel plates 6 in the arc chute 5.

[0044] In addition, the first curved surface and the second curved surface have the same radius of curvature, which facilitates the sliding of the curved slider 3. At the same time, the arc length of the second curved surface is greater than that of the first curved surface, which allows the curved slider 3 to have a larger range of motion. The first curved surface contacts the second curved surface through a polytetrafluoroethylene slide plate. The advantage of this is that the polytetrafluoroethylene slide plate has the effect of reducing friction. When the bridge main beam is unbalanced and tilted, the curved slider 3 tilts. Under the action of gravity, the gravity component in the horizontal direction will allow the curved slider 3 to reset through the polytetrafluoroethylene slide plate, thereby avoiding the bridge main beam from tilting under normal use.

[0045] In the event of a large earthquake, please refer to Figure 3 and Figure 4The bridge pier 4 is first subjected to the vibration force, and then the vibration force is transmitted to the arc-shaped slider 3. Due to the inertia of the bridge main beam, the arc-shaped slider rotates and slides in the arc-shaped slide groove to adapt to the relative rotation between the bridge pier and the main beam, thereby avoiding the plate rubber bearing from generating pure bending stress, thereby achieving the effect of protecting the plate rubber bearing under the action of earthquake, improving the seismic performance of the plate rubber bearing, providing effective protection for construction and rescue, and solving the problem that the rubber bearing in the existing seismic resistance system is prone to pure bending stress under the action of strong earthquakes, resulting in bearing failure. Specifically, there will be a relative rotation between the bridge pier 4 and the bridge main beam. Since the arc-shaped slider 3 is subjected to force and relatively rotates with the arc-shaped slide groove 5, the relative rotation between the bridge pier and the main beam is offset, thereby avoiding the plate rubber bearing 1 from being subjected to pure bending moment, and thus avoiding excessive deformation of the plate rubber bearing 1, achieving the effect of protecting the plate rubber bearing 1, thereby improving the service life of the plate rubber bearing 1, and extending the use time of the plate rubber bearing 1, so that the plate rubber bearing 1 can last longer in an earthquake, providing effective protection for construction and rescue. It should be noted that the friction between the arc-shaped slider 3 and the arc-shaped slide groove 5 is between the friction of rotation during normal use and rotation during an earthquake, thereby ensuring that it is in a stable state during normal use, and can rotate during an earthquake, thereby avoiding excessive deformation of the plate rubber bearing 1.

[0046] In addition, the arc plate flange can also be integrally formed on the arc slider 3 .

[0047] To prevent extreme situations, see Figure 2 and Figure 3 A plurality of rotation limit blocks 7 are symmetrically arranged on the top of the pier 4. The rotation limit blocks 7 are symmetrically arranged around the arc chute 5, and a certain gap is set between the rotation limit blocks 7 and the arc slider 3. The gap here is set according to the maximum inclination angle of the bridge main beam, that is, even if the plate rubber bearing 1 is deformed and fails, the arc slider 3 will resist the rotation limit block 7 to achieve the final support guarantee and improve safety. A polytetrafluoroethylene slide plate is set between the first arc surface and the second arc surface for the arc slider 3 to rotate on the arc chute 5.

[0048] The present invention also provides a bridge system, including a bridge plate rubber bearing anti-seismic system adapted to support rotation and a bridge main beam. The bridge plate rubber bearing anti-seismic system adapted to support rotation is the above-mentioned bridge plate rubber bearing anti-seismic system adapted to support rotation. The bridge main beam is installed above the upper top plate in the bridge plate rubber bearing anti-seismic system adapted to support rotation.

[0049] A torsional force will be generated between the pier 4 and the main beam of the bridge. Since the arc-shaped slider 3 is subjected to force and rotates relative to the arc-shaped slide groove 5, the torsional force generated between the main beams of the bridge is offset, thereby preventing the plate rubber bearing 1 from being subjected to pure bending moment, thereby avoiding excessive deformation of the plate rubber bearing 1, achieving the effect of protecting the plate rubber bearing 1, and thus increasing the service life of the plate rubber bearing 1. On the premise of having the bridge plate rubber bearing seismic system that adapts to support rotation, when the bridge system is subjected to seismic force, the additional force generated by the relative rotation of the main beam and the pier can be effectively released through the above-mentioned bridge plate rubber bearing seismic system that adapts to support rotation, thereby preventing the plate rubber bearing in the bridge system from generating pure bending stress, thereby improving the service life of the plate rubber bearing and reducing the risk of bridge beam falling. Specifically, when the bridge system is subjected to earthquake impact, the pure bending stress generated by the seismic force on the plate rubber bearing 1 can be effectively released through the above-mentioned bridge plate rubber bearing seismic system that adapts to support rotation, thereby preventing the plate rubber bearing 1 in the bridge system from generating pure bending moment, thereby reducing the risk of bridge beam falling in the bridge system and improving the service life of the bridge system.

[0050] A method for installing a bridge plate rubber bearing anti-seismic system adapted to support rotation, comprising the following steps: S1, the plate rubber bearing 1 is connected to the upper top plate 2 and the arc-shaped slider 3 respectively. S2, the plate rubber bearing 1 is placed in the arc-shaped slide 5 set on the top of the pier 4, and the arc-shaped slider 3 is ensured to be in close contact with the arc-shaped slide 5. S3, the pull-out limit steel plate 6 is placed on the arc-shaped plate flanges on both sides of the arc-shaped slider 3, and the pull-out limit steel plate 6 is connected to the pier 1 through bolts 8. S4, the rotation limit block 7 is symmetrically arranged around the arc-shaped slide 5, and fixed on the pier 4 through bolts.

[0051] Under the action of an earthquake, if the top of the bridge pier 4 rotates, the arc-shaped slider 3 can adapt to the rotation by sliding with the arc-shaped slide groove 5, ensuring that the plate-type rubber bearing 1 is in a horizontal rotation state as a whole. If the plate-type rubber bearing 1 is damaged after the earthquake, the bearing can be replaced by disassembling the rotation limit stopper 7 and the pull-out limit steel plate 6 in sequence.

[0052] It should be understood that the specific embodiments described herein are only used to explain the application, rather than to limit it.
