Background technology
Bridge refers to and is erected in rivers,lakes and seas, the building for making traffic etc. that can smoothly pass through, referred to as bridge.Bridge one
As be made of superstructure, substructure, bearing and attached structure, superstructure is also known as bridge span structure, is across obstacle
Primary structure；Substructure includes abutment, bridge pier and basis；Bearing is that bridge span structure is arranged with the bearing place of bridge pier or abutment
Load transfer device；Attached structure then refers to transition slab at bridge head, truncated cone banking, shore protection, training works etc..
Bridge expanssion joint：It refers to meet the requirement of bridge floor deformation, usually between two beam-ends, between beam-ends and abutment
Or expansion joint is set in the articulated position of bridge.It is required that expansion joint is in both directions parallel, perpendicular to bridge axes, equal energy is certainly
It is solid and reliable by stretching, it should be smoothed out when vehicle is run over, without kick and noise；It wants to prevent rainwater and rubbish soil from penetrating into resistance
Plug；Installation, check, maintenance, eliminate dirt will simple and convenient.At setting expansion joint, railing will be disconnected with deck paving.
The effect of bridge expanssion joint:Be to adjust by between the superstructure caused by vehicular load and bridge construction material displacement and
It is coupled.The telescopic device of skew bridge is once destroyed, and will seriously affect speed, comfort and the safety of driving, or even cause to go
Vehicle safety accident.
Application No. is CN204875563U to disclose a kind of bridge based on polyurethane cement and prestress rope such as one
Bracing means, is related to a kind of bridge strengthening device, and the present invention is that there are bonds between fresh and hardened concretes for solution existing highway bridge bracing means
Surface intensity is insufficient, dead weight increases the problems such as larger, tensile capacity improves unobvious.The present invention includes prestress rope and poly- ammonia
Ester cement stabilization layer, prestress rope is mounted on bridge strengthening apparatus surface, using being fixed on after stretching end anchorage tensioning
It is coated on the anchorage of fixed end, on prestress rope and is fixed with polyurethane cement reinforcing layer；It further includes plane formula pressure sensing
