Embodiment 1

[0022] Embodiment one, see figure 1 , figure 2 with image 3 , a bridge deck pier connection structure of a prefabricated bridge, comprising a bridge deck 1, bridge piers 2 and rubber support rods 3.

[0023] An upper assembly hole 11 is provided on the lower end surface of the bridge plate 1 . The opening of the upper assembly hole is integrally formed with an upper assembly hole annular cover 13 . The hole wall of the upper assembly hole is provided with a reinforcement frame 14 on the side wall of the upper assembly hole. The upper hole cover part reinforcement frame 15 is provided in the upper assembly hole annular cover. The upper assembly hole is provided with a pouring hole 16 for the bridge part and an exhaust hole 17 for the bridge part. Both the pouring holes of the bridge plate and the exhaust holes of the bridge plate pass through the upper surface of the bridge plate.

[0024] The lower end surface of the pier 2 is provided with a lower assembly hole 21 . ...

Embodiment 2

[0028] Embodiment two, the difference with embodiment one is:

[0029] see Figure 4 , the lower assembly hole annular cover is provided with permanent magnet 35. After the rubber support rod stretches in, under the effect of the permanent magnet 35, the lower hook connecting rod is turned over and overlapped on the lower assembly hole annular cover. There is no need for artificial magnets to attract and turn over, which improves the convenience of construction.

Abstract

The invention relates to a bridge plate pier connection structure of a prefabricated bridge, which comprises a bridge plate, bridge piers and rubber support rods, an upper assembly hole is provided on the lower end surface of the bridge plate, a lower assembly hole is provided on the lower end surface, and the opening of the upper assembly hole is There is an annular cover for the upper assembly hole on the top to form an annular cover for the upper assembly hole, and an annular cover for the lower assembly hole is provided on the opening of the assembly hole to form an annular cover for the lower assembly hole. There are several lower hook connecting rods, the upper end of the rubber support rod is pierced in the ring cover of the upper assembly hole and the upper hook connecting rod is hooked on the ring cover of the upper assembly hole, concrete is poured in the upper assembly hole, and the lower end of the rubber support rod is pierced In the annular cover of the lower assembly hole and the lower hook connecting rod is hooked on the annular cover of the lower assembly hole, concrete is poured in the lower assembly hole, and a gap is provided between the bridge plate and the bridge pier. The invention has the advantages of extrusion resistance to lateral displacement and vibration resistance, and solves the problem of poor vibration isolation effect between layers of the existing assembled concrete structure.

Description

technical field [0001] The invention relates to bridges, in particular to a bridge plate and pier connection structure of a prefabricated bridge. Background technique [0002] Bridge construction is important in the construction of highways, high-speed railways and urban viaducts. In bridge construction, there are only two ways to construct bridge slabs: one is prefabricated installation construction, and the other is on-site pouring construction. Prefabricated installation construction is to decompose the bridge slab into units and make them in factories or prefabrication yards, and then transport the units that make up the bridge slab to the location of the bridge and install them on the piers. The advantages of this bridge construction method are: the bridge pier and the bridge slab can be constructed in parallel, and the construction period is relatively short; the bridge construction process has little impact on the traffic (navigation) under the bridge. The existing m...
