What is the bridge?

Bridge bearing is a construction method that allows the bridge to transmit strength from its deck down to its base without damage. These bearings are used in bridges, but similar layers can be found roads, docks, airports and other structures where large and heavy objects must function safely. In principle, the surface of the structure and the establishment of the structure between them has a layer that absorbs energy. When the surface is under pressure or is affected by a large force, transfer energy to a layer carrying a bridge that will then send it to the foundation to disperse. Most bridges will have a solid road surface under it and a number of supportive support. There are bearings between the two sections. These bearings will have a wide range of performances, but are generally disproportionately small - much smaller than a road deck and usually less support on which they sit.

The small bearing size allows forces from the road deck to converge to a very small point. When this energy travels down to the foundation, it travels as very compact ifnie strength. Because only a small part of the foundation moves energy, the rest of the system supports it as energy moves. This reduces the cutting force on the base and causes less likely to fail during transmission.

There are three basic forms of bridge load capacity, but countless variations of each type. Each of these forms works best with a certain type of force, so it is not unusual to find one structure with more than one style. Typically, the type and size of the bearing is determined by the expected load and using the structure.

Elastomeric bearing is essentially a layer of a strong elastic polymer. These layers are great for the absorption of energy -resistant movement. They are the most general bridge deposits and are common in almost every main structure. On the other hand, they do not have very little energy.

sliding bearings are produced using two low friction metal plates between them. These structures do not absorb energyII very well, but almost negates the longitudinal forces that are applied to them. When the energy hits the polymer layer, the plate slips and transfers the energy into motion. This drastically reduces the energy moved to the bottom plate.

cylinder deposits are either round balls or rolled rollers similar to a pin. These layers of the negative force at least two directions and, thanks to their thickness, absorb and transmit the remaining energy well. Yet they absorb less than an elastomeric bearing and do not negatively than a sliding bridge.
