[0001] The utility model relates to the technical field of bridge supports, in particular to a temporary connecting piece used on a bridge support. Background Art

[0002] The bridge bearing is an important structural component connecting the superstructure and substructure of the bridge. It is located between the bridge and the pad stone. It can reliably transfer the load and deformation borne by the superstructure of the bridge to the substructure of the bridge. It is an important force transmission device of the bridge. There are two types of bridge bearings: fixed bearings and movable bearings. The commonly used forms include: oil felt or flat bearings, plate rubber bearings, spherical bearings, steel bearings and special bearings.

[0003] The upper and lower bearing plates of the bridge bearings are kept horizontal and coaxial during transportation and installation.

When disassembling, the bolts need to be removed and then the temporary connectors are removed. Therefore, it is not easy to install and disassemble the temporary connectors. Workers need to spend a lot of time when installing and disassembling the temporary connectors, which seriously reduces work efficiency and wastes manpower and material resources.

DETAILED DESCRIPTION

[0030] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0031] Embodiment 1

[0032] like Figure 1-Figure 6 As shown, a temporary connector for a bridge bearing 1 of this embodiment includes an upper bearing plate 11 and a lower bearing plate 12 that are movably connected to each other, and the temporary connector includes a plurality of connector bodies 2 and a plurality of locking mechanisms 3 that correspond one to one with the plurality of connector bodies 2. The plurality of locking mechanisms 3 are detachably mounted on the upper bearing plate 11 and the lower bearing plate 12, respectively.

[0033] Specifically, the connector body 2 is engaged with the locking mechanisms 3 on the upper bearing plate 11 and the lower bearing plate 12, so that the central axes of the upper bearing plate 11 and the lower bearing plate 12 are always the same. By providing a plurality of connector bodies 2 and a plurality of locking mechanisms 3 corresponding to the plurality of connector bodies 2, it is possible to fix the upper bearing plate 11 and the lower bearing plate 12, prevent slippage and deflection between the upper bearing plate 11 and the lower bearing plate 12 when transporting the bridge bearing 1, and improve the connection between the bridge bearing 1 and the upper and lower structures of the bridge. By clamping the connector body 2 with the locking mechanism 3, and the locking mechanism 3 being detachably connected to the upper support plate 11 and the lower support plate 12, it can make the connector body 2 more convenient to install on the locking mechanism 3, and it will also be more convenient to remove the connector body 2 from the locking mechanism 3. Such a setting can not only realize the installation and disassembly of the connector body 2, but also make it easier to install and disassemble, but also reduce the construction time, improve work efficiency, and reduce the required manpower and material resources.

[0034] Further, the connector body 2 is Z-shaped and includes a first clamping portion 21, a connecting portion 22, and a second clamping portion 23 connected in sequence. It should be noted that the first clamping portion 21, the connecting portion 22, and the second clamping portion 23 are preferably connected vertically. The first clamping portion 21 and the second clamping portion 23 are both provided with a clamping hole 24 for clamping with the locking mechanism 3, which can make it more convenient for the connector body 2 to be installed on the locking mechanism 3, and it is also more convenient when the connector body 2 is disassembled from the locking mechanism 3. That is, when installing the connector body 2, it is only necessary to determine the position of the connector body 2, and the locking mechanism 3 passes through the two clamping holes 24, and the connector body 2 is clamped on the locking mechanism 3 through the two clamping holes 24, and the installation of the connector can be completed. When disassembling, it is only necessary to slightly loosen the locking mechanism 3, so that the connector body 2 and the locking mechanism 3 are relatively movable, and the connector body 2 can be taken out along the clamping hole 24 to realize the disassembly of the connector body 2.

[0035] Furthermore, the connector body 2 further includes a clamping groove 25, which is connected to the clamping hole 24, and the clamping groove 25 is used to clamp the connector body 2 with the locking mechanism 3 along the transverse center line of the connector body 2 and perpendicular to the axial direction of the locking mechanism 3. It should be noted that the transverse center line of the connector body 2 is a horizontal straight line from the first clamping portion 21 to the second clamping portion 23. The clamping hole 24 can guide the connector body 2 to be installed or disassembled from the locking mechanism 3, so that the connector body 2 can be accurately clamped on the locking mechanism 3, and the locking mechanism 3 locks the connector body 2, further realizing the temporary fixation of the upper support plate 11 and the lower support plate 12. Preferably, the clamping hole 24 is a U-shaped hole, and the straight section of the U-shaped hole passes through the same side wall of the first clamping portion 21 and the second clamping portion 23, and the arc section of the U-shaped hole is located on the side wall on the same side away from the first clamping portion 21 and the second clamping portion 23. The clamping groove 25 is arc-shaped and the arc is connected with the arc segment of the U-shaped hole. The center points of the clamping groove 25 and the arc segment of the U-shaped hole are located on the same horizontal line. The vertical center axes of the clamping groove 25 and the arc segment of the U-shaped hole are parallel to each other and located in the same plane. When the connector body 2 is installed, the first clamping portion 21 and the second clamping portion 23 can be further clamped with the locking mechanism 3 through the clamping groove 25; when the connector body 2 is disassembled, it is only necessary to pound or pull the clamping groove 25 of the connector body 2 to be detached from the locking mechanism 3 and detach from the first clamping portion 21 and the second clamping portion 23 along the arc segment and the straight segment of the U-shaped hole in turn. The distance between the center point of the clamping groove 25 and the center point of the arc segment of the clamping hole 24 is H, 2mm≤H≤3mm, which can make it easier to disassemble the connector body 2. The worker only needs to use a tool to knock the connector body 2 to detach the locking mechanism 3 from the locking mechanism 3, and then the connector body can be disassembled, thereby improving work efficiency.

[0036] Furthermore, the two slots 25 on the first clamping portion 21 and the second clamping portion 23 extend in opposite directions, which can make the locking mechanism 3 more stable when fixing the connector body 2. Since the pulling direction of the locking mechanism 3 on the connector body 2 is toward the two ends of the connector body 2 when installing the connector body 2, at this time, the two slots 25 are arranged opposite to each other, which can make the locking mechanism 3 more stable when fixing the connector body 2, and prevent the connector body 2 from shaking or falling. At the same time, it can also ensure that the upper support plate 11 and the lower support plate 12 are fixed. Preferably, the radius of the clamping hole 24 is R 1 , the radius of the slot 25 is R 2 , 12mm≤R 1 +R 2 +H≤30mm, and R 1 , R 2 , H changes with the size of the connector body 2, which can improve the applicability of the connector body 2 so as to be able to temporarily fix bridge bearings 1 of different sizes.

[0037] Furthermore, the connection between the first clamping portion 21 and the second clamping portion 23 and the connecting portion 22 is arc-shaped, which can avoid stress concentration on the upper support plate 11 and the lower support plate 12 on the connector body 2 during transportation or installation, thereby avoiding breakage of the connector body 2 and improving the strength of the connector body 2.

[0038] Furthermore, the locking mechanism 3 includes a first bolt 31 and a second bolt 32 , and the first bolt 31 and the second bolt 32 can lock the connector body 2 and keep the connector body 2 and the bridge bearing 1 relatively fixed.

[0039] Specifically, the first bolt 31 and the second bolt 32 are threadedly inserted into the bottom of the upper support plate 11 and the top of the lower support plate 12 respectively, and the connecting member body 2 is respectively clamped with the first bolt 31 and the second bolt 32 through two clamping holes 24 and the bottom wall of the second clamping portion 23 is fitted with the top wall of the lower support plate 12, the top wall of the end of the first bolt 31 away from the upper support plate 11 is fitted with the bottom wall of the first clamping portion 21, and the bottom wall of the end of the second bolt 32 away from the lower support plate 12 can be fitted with the top wall of the second clamping portion 23 to clamp or loosen the second clamping portion 23. By setting the first bolt 31 and the second bolt 32, it is possible to lock the connector body 2. By screwing the first bolt 31 and the second bolt 32, the connector body 2 can be clamped and fixed, so that the first clamping portion 21 is clamped between the upper support plate 11 and the bottom of the first bolt 31, and the second clamping portion 23 is clamped between the lower support plate 12 and the top of the second bolt 32. When disassembling, it is only necessary to screw the first bolt 31 and the second bolt 32 in the opposite direction, and by hammering or pulling, the first bolt 31 and the second bolt 32 are separated from the clamping groove 25 on the first clamping portion 21 and the second clamping portion 23, and the connector body 2 can be taken out in the direction away from the U-shaped hole. Preferably, the locking mechanism 3 also includes a nut 33. The nut 33 is sleeved on the outer wall of the first bolt 31 and the nut 33 is threadedly connected to the first bolt 31, and the bottom wall of the nut 33 can fit with the top wall of the first clamping portion 21. The nut 33 can cooperate with the first bolt 31 to clamp or loosen the first clamping portion 21, and can fix the first clamping portion 21. Since the heights of the upper support plate 11 and the lower support plate 12 are different, when the connector body 2 of uniform specifications is used for fixing, there is a gap between the first clamping portion 21 and the upper support plate 11. Therefore, the nut 33 is provided to clamp the first clamping portion 21 between the nut 33 and the bottom of the first bolt 31, thereby clamping the first clamping portion 21, and at the same time, the applicability of the locking mechanism 3 is improved, the waste of resources is reduced, and the cost is reduced.

[0040] Furthermore, the temporary connector also includes a reinforcing rib 4 and the reinforcing rib 4 is fixedly connected to a side wall of the connector body 2. It can enhance the strength of the connector body 2 and further prevent the connector body 2 from being broken or damaged. By setting the reinforcing rib 4 as a parallelogram, it can reduce the waste of resources and reduce costs. The reinforcing rib 4 is a parallelogram and the side walls of the two short sides of the parallelogram are flush with the top wall of the first clamping part 21 and the bottom wall of the second clamping part 23 respectively. It can reduce the space occupied by the temporary connector, thereby avoiding interference between the reinforcing rib 4 and the upper support plate 11 and the lower support plate 12, thereby avoiding scratches on the upper support plate 11 and the lower support plate 12 when disassembling the connector body 2, reducing the damage rate of the bridge support 1 and the temporary connector, and reducing costs.

[0041] This embodiment has a simple structure and a simple installation and disassembly method, which greatly avoids the phenomenon of the ruler wheel 2 floating, so as to cause the tape measure to get stuck, reduces the damage rate of the tape measure, and reduces the production cost.
