Key words:
High damping isolation rubber bearings, also known as HDR bearings, are products designed according to the national standard GB20688 for domestic high resistance isolation rubber bearings. They are made by adding various additives to natural rubber to improve its damping performance (increase hysteresis loss and reduce storage modulus), and then using this damping rubber to make a laminated product of steel plate and rubber that is similar to the structure of ordinary rubber bearings through thermal vulcanization.
Key words:
Pot type rubber bearings are bridge bearings composed of steel and rubber components. It has the characteristics of high bearing capacity, large horizontal displacement, flexible rotation, light weight, and compact structure. It has the advantages of simple structure, low height, convenient processing, steel saving, and cost saving, making it a suitable support for large-span bridges. The basin support reaches a new height. The need for more modern bridges. It is the soul of the entire bridge. The design coefficient of the room temperature type movable support has been lowered from the original 4, which improves the service life of the support. The structural principle of pot type rubber bearing is that the rubber block placed in the sealed steel pot can bear the vertical load of the bridge with the reaction force generated under the three-way stress. At the same time, the elasticity of the rubber can meet the rotation of the beam end, and the horizontal displacement of the bridge superstructure can be completed through the free sliding of the stainless steel plate welded on the upper seat plate and the polytetrafluoroethylene.
