Adjustable bridge bearing pads

Abstract

The invention discloses an adjustable bridge support cushion stone, which comprises a bottom plate assembly, a height adjustment assembly and a support block for supporting the bridge support, the height adjustment assembly includes a wedge-shaped slider and an adjustment piece, and the wedge-shaped slider It is connected to the bottom plate assembly through the adjustment piece and can move horizontally under the adjustment of the adjustment piece. The support block is placed on the wedge-shaped surface of the wedge-shaped slider and can move up and down with the horizontal movement of the wedge-shaped slider. On the bottom plate assembly A wedge-shaped sliding block limiting plate is provided, and limiting parts are also arranged around the support block. The invention has the advantages of fast and safe support leveling and replacement, simple construction equipment, low labor intensity, high efficiency, avoiding potential safety hazards of bridges, and the like.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to an adjustable bridge support cushion stone which can conveniently replace and level the bridge support. Background technique [0002] At present, the leveling and replacement of bridge supports are generally carried out using the jacking method, that is, after the bridge is lifted by special jacking equipment, the supports are leveled and replaced, and then the beam is dropped. The whole process requires a lot of special equipment, cumbersome procedures, heavy workload, and precise synchronous monitoring to ensure the safety of the bridge, especially for large and medium-sized bridges, which have higher requirements for equipment and construction, otherwise it will easily cause hinge cracks, Accidents such as local concrete damage; at the same time, when a new bridge is installed with supports or bridge piers settle, it is often easy to cause the support to fall out, ...

The whole process requires a lot of special equipment, cumbersome procedures, heavy workload, and precise synchronous monitoring to ensure the safety of the bridge, especially for large and medium-sized bridges, which have higher requirements for equipment and construction, otherwise it will easily cause hinge cracks, Accidents such as local concrete damage; at the same time, when a new bridge is installed with a support or the bridge pier is subsidence, it is often easy to cause the support to fall out, because the height of the support cannot be adjusted, which seriously threatens the operation safety of the bridge
