Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of bridge bearings, and more specifically, it relates to a shock-absorbing and tensile bridge bearing. Background Art
[0002] As a huge building, modern urban bridges are an important part of people's living environment. Urban bridge structures are developing towards rational structural stress, aesthetic bridge forms, and diversified use of materials. Bridge bearings are generally arranged between the upper structure and the piers of the bridge. Their function is to transfer the bearing reaction force of the upper structure, including vertical and horizontal forces caused by dead loads and live loads; to ensure that the structure can deform freely under the action of factors such as live loads, temperature changes, concrete shrinkage, and creep, so that the actual stress conditions of the upper and lower structures conform to the static force diagram of the structure.
[0003] During the construction of existing bridges, the piers and crossbeams are generally connected through bridge bearings. However, the existing bridge bearing structures are relatively simple, divided into two parts: the bearing and the cushion stone. The function of a single rubber bearing is relatively single, and its stability is average. Moreover, the bearing is a whole. When it is damaged and needs to be replaced, only the whole bearing can be replaced, resulting in a high cost. When the existing bridge bearings connect the upper and lower structures of the bridge, they can only play a supporting role and lack a tensile mechanism. In addition, there are stresses inside the bridge, and there is a chance that the bridge will deform and warp under external stimuli. During the construction of the bridge, the cushion stone is directly poured on the pier, and the connection between the cushion stone and the bridge is less, and the connection surface is easily damaged when subjected to shear stress.
