Description

Technical Field

[0001] The utility model relates to the technical field of bridge supports, in particular to a split support. Background Art

[0002] Bridge bearings are key components in bridge structures. They are installed at the ends and mid-span of the bridge and play the important role of supporting the bridge's own weight, bearing train loads, and adapting to the relative displacement between the bridge and the substructure. Bridge bearings can evenly transfer loads to the piers or abutments while ensuring the stability and safety of the bridge during operation. In actual applications, bridge bearings need to have good vertical bearing capacity, sufficient shear resistance, and excellent elastic recovery properties to adapt to different working conditions.

[0003] When existing split-type bridge bearings are used, welded support rods are often used to fix the support top plate and the support bottom plate together. The welded support rods can only be removed after the support installation operation is completed. However, the fixed welded support rods are difficult to remove, and the welded support rods need to be sawed off and removed, and the operation of removing the support rods can only be achieved using devices such as electric saws. This is not only time-consuming and labor-intensive, but also some installation environments are relatively narrow, making it difficult to use electric saws for cutting operations. In addition, after the rubber plate in the existing split bearing is damaged, the bearing may collapse, which will cause serious safety risks to the entire bridge body. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model is provided with a supporting mechanism. By using the supporting mechanism, the fixed connection state between the support top plate and the support bottom plate can be easily released. The user only needs to remove the limit rod and knock the pressure plate to separate the support rod from the limit clamping seat. Then the support rod will naturally fall onto the supporting seat and the slot, avoiding the cumbersome and time-consuming operation of cutting with tools such as electric saws in the traditional welding support rod method, greatly improving the efficiency of installation and maintenance. The traditional welding support rod method has safety hazards during installation and maintenance. For example, cutting with an electric saw may cause sparks, while the supporting rod The mechanism does not need to cut the support rods, which reduces safety risks and ensures the safety and stability of the bridge structure. The design of the supporting mechanism eliminates the need for cutting with tools such as electric saws, saving equipment and labor costs. At the same time, due to the improved convenience of installation and maintenance, the additional economic losses caused by long-term shutdowns are also reduced; when the rubber sheet is damaged, the support rods and the supporting seat can support the bearing top plate and the bearing bottom plate to avoid bearing collapse, providing a lot of time for maintenance, which helps to detect and deal with problems in a timely manner, extend the service life of the bridge, and reduce the frequency of bridge replacement.

[0025] The working principle of the utility model is as follows: the split support is additionally provided with a supporting mechanism 3. When using the split support, it is only necessary to install the split support between the bridge body and the foundation stone. After completing the installation operation of the split support, it is necessary to release the fixed connection state of the support top plate 1 and the support bottom plate 2. The user only needs to remove the first limiting rod 306 so that the first limiting rod 306 no longer limits the position of the first support rod 302, and then knock on the first pressing plate 303 to separate the first support rod 302 and the first limiting clamping seat 304. The displaced first support rod 302 will fall on the first supporting seat 307 and the first slot 308. Similarly, remove the second limiting rod 314 so that the second limiting rod 314 no longer limits the position of the second support rod 310, and then knock on the second pressing plate 311 to separate the second support rod 310 and the second limiting clamping seat 312. The displaced second support rod 310 will fall onto the second supporting seat 315 and the second slot 316, thereby completing the unlocking operation of the support top plate 1 and the support bottom plate 2, which is different from the traditional method of separating the support rods and is faster; in summary, the supporting mechanism 3 replaces the traditional welded support rod to play the role of connecting the support top plate 1 and the support bottom plate 2. However, using the supporting mechanism 3, it is very easy to release the fixed connection state of the support top plate 1 and the support bottom plate 2. It is only necessary to release the support rod limit and knock the displaced support rod to release the connection state of the support top plate 1 and the support bottom plate 2 to achieve the unlocking effect. In addition, the displaced support rod will be supported by the supporting seat. After the rubber plate 5 collapses in the later stage, the support rod and the supporting seat will support the support top plate 1 and the support bottom plate 2 to avoid collapse between the support top plate 1 and the support bottom plate 2, providing a lot of time for maintenance.
