Extensible connection device for bridge with extensible structure falling water groove

Abstract

The invention discloses an extensible connection device for a bridge with an extensible structure falling water groove. The extensible connection device is arranged between adjacent bridge deck slabs and comprises a pair of upper-portion guide plates, the lower-portion falling water groove, a connecting rope and a connecting support, wherein the pair of upper-portion guide plates is symmetrically arranged between side walls of the adjacent bridge deck slabs, the top ends of the upper-portion guide plates are fixedly arranged inside the adjacent bridge deck slabs, and folding plates extending downward and obliquely are arranged at the bottom ends of the upper-portion guide plates. The connecting support is fixedly arranged on the side walls of the bridge deck slabs and connected with one end of the connecting rope, the other end of the connecting rope is connected with the outside of the lower-portion falling water groove, a water collecting space with an upward opening is arranged inside the lower-portion falling water groove, and the tail ends of the folding plates are arranged in the water collecting space. The extensible connection device is simple in structure, the upper-portion guide plates and the lower-portion falling water groove are of independent double structures, extension of the bridge deck slabs does not cause distortion of the connecting parts, and the service life of members is prolonged.

Description

technical field [0001] The invention belongs to a bridge connection device, in particular to a telescopic connection device for a bridge with a telescopic structure gutter. Background technique [0002] When building a bridge, a plurality of supports must first be erected, on which steel structures are used to form supports, and concrete is poured on these supports to form a bridge deck, which is usually paved with asphalt like roads. The connection between these bridge decks is scalable, and the temperature changes caused by the seasons cause the above bridge decks to expand with heat and contract with cold in the length direction. Considering the expansion and contraction of these bridge decks, there should be telescopic connections between the bridge decks The device can not only protect the bridge from damage caused by thermal expansion and contraction, but also ensure the smooth passage of vehicles. The telescopic auxiliary material of the gutter of the traditional tel...
