Description

Technical Field

[0001] This utility model relates to the field of temporary connection device technology, and in particular to a novel temporary connection device for bridge bearings. Background Technology

[0002] Temporary connection devices are used to ensure that bridge bearings do not experience displacement, changes in height at the four corners, or other adverse factors during hoisting, transportation, and installation.

[0003] The inventors discovered the following unresolved problems in the existing technology: 1. Most of the current temporary connection devices are "Z"-shaped and "L"-shaped. Both structures rely on the strength (thickness) of the steel plate and the quality of manual welding and bending, with human factors accounting for the majority.

[0004] 2. The different structural dimensions of each bridge bearing result in different span spacings. However, temporary connection structures with similar dimensions require on-site workers to use rulers to measure during the search process, significantly reducing work efficiency.

[0005] 3. Furthermore, during the installation process, the hole spacing often changes due to the problem of bending verticality, which leads to difficulties in the installation of temporary connection devices and bridge bearings. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a novel temporary connection device for bridge bearings.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a novel temporary connection device for bridge bearings, comprising an upper bearing plate and a lower bearing plate, wherein a connecting plate assembly is provided between the upper bearing plate and the lower bearing plate, and connecting bolts are provided between the connecting plate assembly and the upper bearing plate, and between the connecting plate assembly and the lower bearing plate.

[0008] The effect achieved by the above-mentioned components is as follows: when using the temporary connection device, the bridge bearing is placed between the upper bearing plate and the lower bearing plate of the bridge bearing, and the connecting bolts between the connecting plate assembly and the upper bearing plate, and between the connecting plate assembly and the lower bearing plate are tightened, thereby clamping and fixing the bridge bearing between the upper bearing plate and the lower bearing plate. This minimizes human factors in the manufacturing process, and one model of temporary connection device can be used on many different models of bridge bearings without affecting the hole spacing during installation.

[0009] Preferably, the connecting plate assembly is a parallelogram plate, and a limiting hole is provided on the front side of the connecting plate assembly. A limiting block is provided on the inner wall of the limiting hole, and the limiting block is threadedly connected to the connecting bolt.

[0010] The effect achieved by the above components is as follows: when the limiting block is placed in the limiting hole on the connecting plate assembly, during the process of screwing the connecting bolt into the upper and lower seat plates, the contact surface between the connecting bolt and the connecting plate assembly gradually becomes parallel. During the deformation of the connecting plate assembly, it will gradually come into force contact with the limiting block, thereby restricting the movement of the connecting bolt.

[0011] Preferably, the limiting block is a nut that matches the connecting bolt.

[0012] The effect achieved by the above components is that, by setting the limit block as a nut that matches the connecting bolt, the connecting bolt is inserted into the connecting plate assembly, so that it is threadedly connected with the nut.

[0013] Preferably, the limiting hole is perpendicular to the edge of the connecting plate assembly.

[0014] The effect achieved by the above components is that, since the limiting hole is perpendicular to the edge of the connecting plate assembly, the contact surface between the connecting bolt and the connecting plate assembly gradually becomes parallel as the connecting bolt is screwed into the upper and lower seat plates.

[0015] Preferably, the connecting bolt is slidably inserted into the connecting plate assembly, and the limiting block is perpendicular to the connecting bolt.

[0016] The effect achieved by the above components is as follows: Since the limiting block is perpendicular to the connecting bolt, during the process of screwing the connecting bolt into the upper and lower seat plates, the contact surface between the connecting bolt and the connecting plate assembly gradually becomes parallel. During the deformation of the connecting plate assembly, it will gradually come into contact with the limiting block, thereby restricting the movement of the connecting bolt.

[0017] Preferably, bolt holes are provided on one side of the upper bearing plate and the lower bearing plate of the bridge bearing, and the bolt holes are adapted to the connecting bolts.

[0018] The effect achieved by the above components is that the connecting bolts are connected to the upper and lower base plates by setting bolt holes.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] In this invention, human factors are virtually nonexistent during the manufacturing process, and a single model of temporary connection device can be used on many different models of bridge bearings without being affected by the hole spacing during installation. Attached Figure Description

[0024] Reference Figure 1 As shown, this utility model provides a technical solution: a novel temporary connection device for bridge bearings includes an upper bearing plate 1 and a lower bearing plate 2.

[0025] Reference Figure 1 and Figure 2 As shown in this embodiment: a connecting plate assembly 4 is provided between the upper bearing plate 1 and the lower bearing plate 2 of the bridge bearing. Connecting bolts 3 are provided between the connecting plate assembly 4 and the upper bearing plate 1, and between the connecting plate assembly 4 and the lower bearing plate 2. When using the temporary connection device, the bridge bearing is placed between the upper bearing plate 1 and the lower bearing plate 2, and the connecting bolts 3 between the connecting plate assembly 4 and the upper bearing plate 1, and between the connecting plate assembly 4 and the lower bearing plate 2, are tightened, thereby clamping and fixing the bridge bearing between the upper bearing plate 1 and the lower bearing plate 2. This minimizes human error during the manufacturing process, and one model of temporary connection device can be used on many different models of bridge bearings. When used on the base, the hole spacing will not be affected during installation. The connecting plate assembly 4 is a parallelogram plate with a limit hole on the front. The inner wall of the limit hole is provided with a limit block 5. The limit block 5 is threadedly connected to the connecting bolt 3. When the limit block 5 is placed in the limit hole on the connecting plate assembly 4, the contact surface between the connecting bolt 3 and the connecting plate assembly 4 gradually becomes parallel as the connecting bolt 3 is screwed into the upper and lower base plates. During the deformation of the connecting plate assembly 4, it will gradually come into force contact with the limit block 5, thereby restricting the movement of the connecting bolt 3. The limit block 5 is a nut that matches the connecting bolt 3. By setting the limit block 5 as a nut that matches the connecting bolt 3, the connecting bolt 3 is inserted into the connecting plate assembly 4, so that it is threadedly connected to the nut.

[0026] Reference Figure 1 and Figure 2As shown in this embodiment: the limiting hole is perpendicular to the edge of the connecting plate assembly 4. Because the limiting hole is perpendicular to the edge of the connecting plate assembly 4, the contact surface between the connecting bolt 3 and the connecting plate assembly 4 gradually becomes parallel during the process of screwing the connecting bolt 3 into the upper and lower seat plates. The connecting bolt 3 slides into the connecting plate assembly 4. The limiting block 5 is perpendicular to the connecting bolt 3. Because the limiting block 5 is perpendicular to the connecting bolt 3, the contact surface between the connecting bolt 3 and the connecting plate assembly 4 gradually becomes parallel during the process of screwing the connecting bolt 3 into the upper and lower seat plates. During the deformation of the connecting plate assembly 4, it will gradually come into force contact with the limiting block 5, thereby restricting the movement of the connecting bolt 3. The connecting bolt 3 slides into the connecting plate assembly 4. The limiting block 5 is perpendicular to the connecting bolt 3. By setting the bolt hole, the connecting bolt 3 is connected to the upper and lower seat plates.

[0027] Working principle:

[0028] When using the temporary connection device, the bridge bearing is placed between the upper bearing plate 1 and the lower bearing plate 2. The connecting bolts 3 between the connecting plate assembly 4 and the upper bearing plate 1, and between the connecting plate assembly 4 and the lower bearing plate 2, are tightened to clamp and fix the bridge bearing. This minimizes human error during manufacturing and allows one model of temporary connection device to be used on many different models of bridge bearings without affecting the hole spacing during installation. The limiting block 5 is placed in the limiting hole on the connecting plate assembly 4, with the limiting hole perpendicular to the edge of the connecting plate assembly 4. As the connecting bolts 3 are screwed into the upper and lower bearing plates, the contact surfaces of the connecting bolts 3 and the connecting plate assembly 4 gradually become parallel. The limiting block 5 is perpendicular to the connecting bolts 3. During the deformation of the connecting plate assembly 4, it gradually comes into contact with the limiting block 5, thereby restricting the movement of the connecting bolts 3.
