Description
Technical Field
The utility model relates to a landscape bridge field especially relates to a prefabricated double arch bridge middle part connected node structure.
Background
Along with the improvement of living standard of people, gardens are the excellent place that people had a rest and play, also develop fast, and the arch bridge is one of the common facility in landscape, and traditional arch bridge adopts cast-in-place construction, but need build the template, tie up the reinforcing bar and maintain, and this makes the engineering time longer undoubtedly, therefore prefabricated arch bridge begins to implement, but the arch bridge node is still undefined, leads to having no reliable technical reference during the construction, consequently easily causes a series of problems, such as the steadiness of structure.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to prior art's defect with not enough, provide a prefabricated two arch bridge middle part connected node structure, this prefabricated two arch bridge middle part connected node structural design is reasonable, and the structure is firm, and the deformation that adaptable arch bridge takes place.
In order to achieve the above object, the utility model adopts the following technical scheme: a prefabricated double-arch bridge middle connecting node structure comprises a first arch bridge, a second arch bridge, bridge piers, seams, U-shaped connecting steel plates, chemical anchor bolts, a V-shaped structure and a caulking paste layer; the first arch bridge and the second arch bridge are both prefabricated by reinforced concrete, and the end parts of the first arch bridge and the second arch bridge are arranged on the top surface of the bridge pier; a seam is reserved between the first arch bridge and the second arch bridge on the bridge pier; a U-shaped connecting steel plate is arranged between the bottom surfaces of the end parts of the first arch bridge and the second arch bridge and the top surface of the pier, and the notch of the U-shaped connecting steel plate is upward; the middle edge of the U-shaped connecting steel plate is fixed on the top surface of the bridge pier through two chemical anchor bolts, and two side edges of the U-shaped connecting steel plate are respectively fixed on the outer side surfaces of the end parts of the first arch bridge and the second arch bridge through the chemical anchor bolts; a V-shaped structure is arranged at the joint of the U-shaped connecting steel plate; and the joints are filled with caulking paste layers.
Preferably, the width of the seam is 30-50 mm.
The utility model has the advantages that: this prefabricated two arch bridge middle part connected node structural design is reasonable, and the structure is firm, has water-proof effects, and the deformation that adaptable arch bridge takes place.
