Cover beams and tie beams, pad stones and supports

cap beam

Bent cap refers to the horizontal beam set at the top of the bent pile pier to support, distribute, and transmit the load of the upper structure. Also known as hat beam. Install reinforced concrete or low reinforcement concrete beams on bridge piers (abutments) or piles.

tie beam

A tie beam refers to a beam that acts as a tension rod, mainly used to connect two piles or piers into a cohesive force. For example, in a bridge, in order to improve the structure of columns and piles and enhance the overall stiffness of piles or piers, a tie beam is added between the two columns.

Pad stones and supports

Pad stone

Location: Located at the connection between the bridge abutment, pier top, and support, mostly poured on-site with concrete.

Function: The reinforcing bars of the cushion stone are connected by spot welding. When constructing the bridge pier cover beam, attention should be paid to the placement of the embedded bars. The top surface of the cushion stone must be kept flat and clean to ensure a tight fit with the support

support

Bridge bearings are important structural components that connect the upper and lower structures of a bridge. It can reliably transmit the reaction force and deformation (displacement and rotation) of the upper structure of the bridge to the lower structure of the bridge, so that the actual stress situation of the structure is consistent with the theoretical diagram of the calculation.

Its function is to fix the upper structure to the pier, bear various forces acting on the upper structure, and reliably transmit them to the pier; Under the action of load, temperature, concrete shrinkage and creep, the support can adapt to the rotation and displacement of the upper structure, allowing the upper structure to deform freely without generating additional internal forces.
