Description

Integral anchoring guide rail type bridge seamless expansion device Technical Field The utility model belongs to the technical field of bridge engineering, and particularly relates to a seamless expansion device of an integrally anchored guide rail type bridge. Background Because the bridge can cause longitudinal expansion deformation under the effect of factors such as temperature change, load effect, in order to avoid bridge structure to produce the destruction because of receiving too big stress, guarantee bridge floor to be convenient for the vehicle pass in succession simultaneously, prevent that rainwater from oozing out and polluting the substructure, can set up telescoping device between the roof beam body or the roof beam body and abutment of bridge parting department generally. The expansion device commonly used in bridge engineering at present mainly comprises a modular type steel expansion joint and a comb plate type expansion joint, and the two expansion joints have certain problems in use. The modular steel expansion joint mainly comprises steel beams arranged at two sides of the joint and a water stop rubber belt connected in the middle, and a middle beam is arranged in the middle of the joint when the expansion amount is large. The expansion joint has the following problems: (1) When the vehicle passes through, the noise is larger, and when the urban bridge is used, the complaints of surrounding residents are more, and the main reason is that gaps which are long along the transverse direction of the bridge exist between the steel beams, the gaps are perpendicular to the driving direction of the road, and when the vehicle passes through, the wheels deform and impact with the steel beams, so that larger noise is formed. (2) The section of the expansion joint steel beam is mostly C-shaped, the steel plate of the beam body is in a cantilever state, the rigidity is low, buckling deformation and even fracture and falling off easily occur under the action of frequent impact of a vehicle, the normal use function and durability of the expansion joint are affected, and the noise when the vehicle passes is aggravated. (3) The water stopping effect of the expansion joint is realized only by the water stopping rubber belt suspended between the steel beams, the rubber belt is thinner, the expansion joint is easy to damage under the direct actions of steel beam deformation, vehicle impact, road surface sundry piercing and the like, the durability is poor, and the condition that bridge decks are polluted by seepage of bridge decks under the rain water often occurs. Comb plate expansion joints are generally composed of comb-type steel plates, stainless steel sliding plates, neoprene plates, anchor bolts and the like. The facing plate is a comb-shaped anti-slip groove steel plate which is meshed with each other at the gap of the bridge extending from left to right, the expansion and contraction are realized by opening and closing the toothed plate back and forth. The stainless steel sliding plate and the rubber sealing strip are arranged below the panel to form a waterproof and dustproof system. The expansion joint has no transverse through-length gap, the toothed plates are mutually overlapped, and compared with the modular steel expansion joint, the running is smoother, but the following problems still exist: (1) Gaps with the same road running direction exist between toothed plates, and the problem of wheel impact noise still exists. And in urban use, the situation that the bicycle is turned over and hurt people is caused by the fact that the bicycle wheels are clamped into the slots for many times exists, so that potential safety hazards exist. (2) The toothed plate lacks vertical limiting measures, and the vehicle can generate upwarp deformation under the long-term impact action, so that the driving comfort is reduced, the impact noise is increased, and potential safety hazards are caused to the passing vehicle. (3) The panel adopts the bolt anchoring to assemble, and the bolt loosens easily and drops under vehicle load vibration, causes the fishback displacement to drop, and influences service function, security and durability. (4) Silt and garbage easily enter the expansion joint through gaps among toothed plates, so that the expansion joint is not smooth or components are damaged, and the expansion joint is not easy to clean. In summary, the conventional modular steel expansion joints and comb plate expansion joints of the bridge have the problems of noise pollution, easy deformation of steel plates, poor water stopping performance, poor durability and the like, which are mainly caused by the basic structural forms of the two expansion joints, the expansion mode surfaces of the expansion joints have obvious cracks, the structural integrity is not strong, the rigidity of the expansion steel plates bearing rolling of vehicles is low, the expansion steel plates are separated from each other, and effectiv
