Embodiment 1

[0021] Embodiment one, see figure 1 , figure 2 and image 3 , a method for connecting bridge slabs and piers of a prefabricated bridge,

[0022] The first step is to set an upper assembly hole 11 on the lower end surface of the bridge plate 1, and an upper assembly hole annular cover 13 is integrally formed on the opening of the upper assembly hole, and a steel bar for the upper assembly hole side wall is provided in the hole wall of the upper assembly hole The frame 14 and the upper assembling hole annular cover are provided with an upper hole cover part reinforcement frame 15 to improve the structural strength of the upper assembling hole wall and the upper assembling 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. A lower assembly hole 21 is...

Embodiment 2

[0029] Embodiment two, the difference with embodiment one is:

[0030] see Figure 4 , the lower assembly hole annular cover is provided with permanent magnet 35. In the fifth step, the lower hooking rod is rotated under the adsorption of the ring-shaped permanent magnet so as to overlap the ring-shaped cover of the lower assembly hole. There is no need for artificial magnets to attract and turn over, which improves the convenience of construction.

Abstract

The invention relates to a plate and pier connecting method for a precast bridge. The plate and pier connecting method for the precast bridge comprises, firstly, forming an upper mounting hole in a bridge plate, forming a lower mounting hole in a pier, and manufacturing a rubber support rod; secondly, inserting the lower end of the rubber support rod into the lower mounting hole; thirdly, fixing the bridge plate above the pier in a liftable mode; fourthly, inserting the upper end of the rubber support rod into the upper mounting hole; fifthly, lapping a lower hooking rod onto the ring-shaped cover of the lower mounting hole and an upper hooking rod onto the ring-shaped cover of the upper mounting hole; sixthly, casting concrete into the upper mounting hole and the lower mounting hole; seventhly, after the concrete inside the upper mounting hole and the lower mounting hole is solidified, removing support structures. The plate and pier connecting method for the precast bridge solves theproblem of poor interlayer vibration isolating effects of existing prefabricated concrete structures.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a method for connecting bridge slabs and piers 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) u...
