Embodiment Construction

[0038] The following is attached Figure 1-6 The application is described in further detail.

[0039] The embodiment of the present application discloses an assembled beam-slab bridge reinforcement structure and a reinforcement method thereof. refer to figure 1 and figure 2 , the prefabricated girder-slab bridge reinforcement structure includes a pier body 1, the pier body 1 is poured and formed on the ground, the top of the pier body 1 is installed with a seismic isolation support 3, and the top of the seismic isolation support 3 is installed with a beam-slab bridge body 2; When the girder-slab bridge body 2 shakes, the shock-isolation bearing 3 can counteract a part of the girder-slab bridge body 2's shaking, thereby increasing the service life of the girder-slab bridge body 2 . The seismic isolation support 3 includes a lower mounting plate 31 and an upper mounting plate 32; the lower mounting plate 31 is placed on the top of the pier body 1, the lower mounting plate 31...

Abstract

The invention relates to the field of beam-slab bridges, in particular to an assembly type beam-slab bridge reinforcing structure and a reinforcing method thereof.The assembly type beam-slab bridge reinforcing structure comprises a pier body, a beam-slab bridge body and a seismic isolation support, and the seismic isolation support comprises a lower mounting plate mounted on the pier body and an upper mounting plate mounted on the beam-slab bridge body; a connecting part is mounted on the lower mounting plate, a damping part is mounted on the upper mounting plate, the damping part comprises a damping cylinder mounted on the upper mounting plate and a damping rod mounted on the connecting part, and a damping spring is fixedly connected to the inner wall of the damping cylinder and fixedly connected with the damping rod. The assembly type beam-slab bridge reinforcing method comprises the following steps that a pier body is poured on the ground; a shock insulation support is mounted at the top of the pier body; the prefabricated type beam slab bridge body is hoisted to the position above the shock insulation support; the driving component is started to adjust the height of the beam slab bridge body. The problem that a shock insulation support is poor in shock absorption effect is solved.

Description

technical field [0001] The present application relates to the field of girder-slab bridges, in particular to an assembled girder-slab bridge reinforcement structure and a reinforcement method thereof. Background technique [0002] At present, the prefabricated superstructure of bridges is the structural form often used in the superstructure of highway bridges. This structural form and construction technology have the characteristics of saving construction equipment, improving construction conditions, speeding up construction progress, facilitating factory production, and reducing construction costs. [0003] In the related art, when the girder-slab bridge is erected on the pier, a seismic isolation bearing will be installed between the beam-slab bridge and the bridge pier. The seismic isolation bearing usually includes a lower connecting plate and an upper connecting plate, and the upper end surface of the lower connecting plate is installed There are several steel plates an...
