Description

Technical Field

[0001] The utility model belongs to the field of bridge construction engineering, and particularly relates to a pot-type support with an intermediate guide structure. Background Art

[0002] The pot-type bearing is an important component connecting the superstructure and substructure of the bridge. It can reliably transmit the reaction force and deformation of the superstructure of the bridge to the substructure of the bridge. The pot-type bearing is widely used due to its advantages such as uniform reaction force, small rotational torque, and adaptability to large rotation angles.

[0003] One-way movable basin-type bearings are usually implemented using the following two structures. The first is to set limit blocks on both sides of the top plate, forming a structure with one direction limit and the other direction sliding with the two sides of the bottom basin. The defect of this structure is that when the vertical rotation angle of the bearing becomes larger, the limit blocks on both sides of the top plate will interfere with the bottom basin structure, affecting the rotation performance of the bearing. In addition, when the longitudinal temperature displacement direction of the bridge is inconsistent with the displacement center of the bearing, the sliding direction of the limit blocks on both sides of the top plate will have an angle with the bottom basin, resulting in the inability to realize the sliding function and getting stuck.

[0004] The second method is to cut grooves on the top surface of the middle steel liner and set up a separate sliding guide strip. This structure also has certain defects. First, due to the limited external dimensions of the middle steel liner (not exceeding the outer diameter of the pressure-bearing rubber plate in the bottom basin), the length of the guide strip is limited. Secondly, the guide strip and the middle steel liner adopt a split structure and are fixed with bolts. In the above cases, the horizontal bearing capacity of the guide strip is limited, and it is not suitable for use in supports that bear large horizontal forces. In addition, due to the thickness limitation of the middle steel liner, when the guide strip is bolted, it needs to be fixed downward from the middle steel liner groove, which often drills through the middle steel liner and affects the force on the lower rubber pressure plate. Utility Model Content

[0005] The main technical problem solved by the utility model is to provide a pot-type support with an intermediate guide structure, which can solve the problems of the existing two unidirectional movable pot-type supports.

[0006] In order to solve the above technical problems, the present invention adopts a technical solution: a pot-type support with an intermediate guide structure, comprising a top plate and a bottom pot, wherein the top plate is mounted on the bottom pot, and the top plate and the bottom pot are connected via the intermediate guide structure;

[0007] The intermediate guide structure includes a horizontal displacement structure for realizing intermediate guide displacement of the support top plate, an intermediate steel lining plate installed in the bottom basin cavity, and a vertical corner structure for realizing the vertical corner function of the support.

The guide bar is arranged in the middle of the bottom surface of the top plate and is formed by integral processing along the main sliding direction. The guide groove is opened in the middle of the middle steel lining plate to cooperate with the guide bar.

[0009] In a preferred embodiment of the present invention, a groove is provided on the upper surface of the middle steel liner, a flat wear-resistant plate is installed in the groove, and a lateral sliding bar is installed on the inner side wall of the guide groove.

[0010] In a preferred embodiment of the present invention, an L-shaped stainless steel plate is further installed on the bottom surface of the top plate, and the horizontal surface and vertical surface of the L-shaped stainless steel plate are respectively matched with the flat wear-resistant plate and the lateral sliding strip.

[0011] In a preferred embodiment of the present invention, the vertical corner structure is a rubber pressure-bearing plate, and the rubber pressure-bearing plate is installed between the middle steel liner and the pelvic cavity.

[0012] In a preferred embodiment of the present invention, a concave platform is provided on the rubber pressure plate, and the concave platform, the bottom of the middle steel liner and the inner wall of the pelvic cavity form an installation groove, and a brass sealing ring is installed in the installation groove.

[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0021] See also Figures 1 to 5 , an embodiment of the utility model includes: a pot-type support with an intermediate guide structure, including a top plate 1 and a bottom basin 2, the top plate 1 is installed on the bottom basin 2, the top plate 1 is in contact with the bottom of the bridge beam, and transmits the upper structure load.

[0022] The bottom basin 2 is the product base, which is provided with the basin cavity 3, which confines the middle steel liner 6, the rubber pressure plate 7 and the brass sealing ring 8 therein, and the lower part contacts the pad stone on the top of the pier to transfer the upper structure load to the pier.

[0023] The top plate 1 and the bottom basin 2 are connected by an intermediate guide structure. The intermediate guide structure can solve the problems of the two existing one-way movable basin supports. The basin support is provided with the guide bar 10 at the midline position of the lower plane of the top plate 1. It is integrally processed with the top plate 1 and does not require bolt fixation and has high force strength. It solves the problems of rotational interference and jamming during displacement that may occur when the guide bar 10 is provided on both sides of the top plate 1.

[0024] At the same time, the guide groove 11 is opened in the plane of the middle steel lining plate 6, which matches the guide bar 10. When there is an angle between the displacement direction of the bridge and the center line of the support along the bridge, the middle steel lining plate 6 can rotate freely in the plane within the basin 3 to adapt to the actual displacement direction, thereby ensuring that the support can withstand the actual needs of horizontal loads and displacements.

[0025] The intermediate guide structure includes a horizontal displacement structure for realizing intermediate guide displacement of the support top plate 1, an intermediate steel lining plate 6 installed in the basin cavity 3 of the bottom basin 2, and a vertical corner structure for realizing the vertical corner function of the support.

[0026] While transmitting the upper vertical load, the middle steel lining plate 6 can adapt to the disturbance of the upper bridge structure due to various reasons such as load by following the rotation of the rubber pressure plate 7 below, and can also rotate in plane within the bottom basin 2.

[0027] The horizontal displacement structure includes a guide bar 10 and a guide groove 11. The guide bar 10 is arranged in the middle of the bottom surface of the top plate 1 and is integrally processed along the main sliding direction. The guide groove 11 is opened in the middle of the middle steel liner 6 to cooperate with the guide bar 10.

[0028] A groove is formed on the upper surface of the middle steel liner 6, and a flat wear-resistant plate 5 is installed in the groove. The flat wear-resistant plate 5 is made of polymer material and coated with grease on the surface, which can provide a lower friction coefficient.

[0029] A lateral sliding bar 9 is installed on the inner side wall of the guide groove 11, and the lateral sliding bar 9 is fixed to the bottom basin 2 by countersunk copper screws.

[0030] An L-shaped stainless steel plate 4 is also installed on the bottom surface of the top plate 1 , and the horizontal surface and vertical surface of the L-shaped stainless steel plate 4 are matched with the flat wear-resistant plate 5 and the lateral sliding bar 9 respectively.

[0031] The stainless steel plate 4 is mirror-finished and has a low friction coefficient. After bending, it is welded to the top plate 1 and contacts with the flat wear-resistant plate 5 and the lateral sliding bar 9 to form a friction pair, adapting to the displacement changes of the beam body caused by temperature and braking force.

[0032] The vertical corner structure is a rubber pressure plate 7, which is installed between the middle steel lining plate 6 and the basin cavity 3. The rubber pressure plate 7 is used to transfer vertical loads and can also realize the vertical corner function of the support through its own deformability.

[0033] A recessed platform is provided on the rubber pressure plate 7, and the recessed platform, the bottom of the middle steel lining plate 6 and the inner wall of the pelvic cavity 3 form an installation groove. A brass sealing ring 8 is installed in the installation groove. The brass sealing ring 8 exerts a restraining effect on the rubber pressure plate 7 to prevent the rubber pressure plate 7 from being squeezed out during the rotation of the middle steel lining plate 6.

[0034] The guide bar 10 is arranged below the top plate 1, is integrally processed with the top plate 1 and is longer than the plane size of the middle steel lining plate 6. It is safe and reliable in force and can meet the displacement requirements. At the same time, the guide groove 11 is opened in the middle position above the middle steel lining plate 6 and the lateral sliding bar 9 is installed. After being assembled with the guide bar 10 at the bottom of the top plate 1, the middle guide displacement can be realized. Since the middle guide bar 10 can drive the middle steel lining plate 6 to rotate in the plane of the bottom basin 2, it can adapt to the need of lateral bending of the beam body due to installation axis error or sunlight influence of long and large continuous beam bridges, and no jamming will occur. Since the guide bar 10 is arranged at the center line position of the middle steel lining plate 6, the interference phenomenon during rotation when the top plate 1 is provided with block blocks 12 on both sides is avoided.

[0035] Compared with the existing technology, the utility model is a pot-type support with an intermediate guide structure. The pot-type support is provided with an intermediate guide structure, which can solve the problems of the existing two unidirectional movable pot-type supports.

[0036] The basin-type support is provided with a guide strip at the midline position of the lower plane of the top plate, which is processed integrally with the top plate. It does not require bolt fixation and has high force strength, solving the problems of rotational interference and jamming during displacement that may occur when the guide strips are provided on both sides of the top plate.

[0037] At the same time, a guide groove is opened on the plane of the middle steel liner to match the top plate guide strip. When there is an angle between the displacement direction of the bridge and the center line of the support along the bridge, the middle steel liner can rotate freely in the plane within the basin to adapt to the actual displacement direction, thereby ensuring that the support can withstand the actual needs of horizontal loads and displacements.
