Connected support applicable to mounting precast beam

Abstract

The invention discloses a connected support applicable to mounting a precast beam. The connected support comprises a connected steel plate, a plurality of upper positioning connectors fixedly connected with the precast beam are arranged on the upper side of the connected steel plate, the lower side of the connected steel plate is fixedly connected with a first support body through a first upper steel plate and is fixedly connected with a second support body through a second upper steel plate, the upper positioning connectors are positioned between the first support body and the second support body, a first lower steel plate is further fixedly arranged below the first support body, a second lower steel plate is further fixedly arranged below the second support body, and a plurality of lower positioning connectors fixedly connected with a bridge pier cap beam are arranged on the first lower steel plate and the second lower steel plate respectively. The connected steel plate on the connected support is integrally connected with the precast beam, the connected support has the advantages of better durability, firmness in connection, convenience in construction and the like, and close contact between the connected support and the upper precast beam and between the connected support and the lower bridge pier cap beam can be ensured by means of cast-in-situ cushion block construction.

Description

technical field [0001] The invention relates to the technical field of road and bridge construction, in particular to a conjoined support suitable for the installation of prefabricated beams. Background technique [0002] At present, the bearings installed at the bottom of prefabricated beams usually adopt the types of ordinary plate rubber bearings, basin rubber bearings, spherical steel bearings, and lead core rubber bearings. [0003] Ordinary plate-type rubber bearings have a small bearing tonnage. They are connected with the upper and lower structures by friction, and adapt to the expansion and contraction of the bridge by their own shear deformation, but they cannot resist large horizontal forces and deformation requirements. Due to the aging of materials And other reasons, the service life is shorter and the durability is poor. [0004] Basin rubber bearings, spherical steel bearings, lead rubber bearings and other forms of bearings have a long service life, good dur...

Problems solved by technology

However, this technical solution, on the one hand, is still a four-point support, which is difficult to adapt to the natural law of three points and one surface. The prefabricated beam bottom and the support are not easy to fit closely, and the force is uneven, which will increase the noise when driving.

On the other hand, with the increase in the variety and quantity of pads, it will bring great difficulties to construction cost, management and quality control.
