[Bridge expansion joints and construction process principles] [ready] bridge expansion joint device consists of two side members and embedded in the side of the beam duckbill ribbon rubber seal components. This kind of structure is connected by a rigid, load transfer, reliable power transmission; good mechanical seal, dustproof, waterproof performance; its elastic support can silencer damping; using bird-shaped steel beam between two rubber strips to achieve retractable function. So that when the vehicle through convergence at Bridge, can minimize the impact load, both to ensure the normal operation of the highway, extending the useful life, and make the occupants feel smooth and comfortable. Bridge expansion joints [1] Construction operation points, construction preparation work (1) when the slab and precast bridge abutment back wall construction, design requirements should be embedded anchor bars, reserved slots. (2) when the slab installation, expansion joints in the pier, the stage properly resize the gap to meet the mounting width] [bridge expansion joint device required. (3) In order to ensure the passage before paving asphalt pavement construction vehicles in the notch between the embedded steel filled with sand or sandy soil, the top surface of the exposed parts of their embedded steel should be higher than the top surface of 1-2cm, to protect the steel will not be crushed. (4)] [bridge expansion joints and low pre-construction prices in Guangdong bridge expansion joints required to report detailed construction design scheme requires meticulous organization, co-ordination arrangements, clarify responsibilities, responsibilities clearly and strictly controlled in accordance with the construction specifications. (5) familiar with the drawings, installation procedures, and training procedures for construction of bridge expansion joints [] position number to check the manufacturers full range of bridge expansion joints, expansion joints on straight, flatness and torsional pitch inspection inspection. [Bridge] telescopic steel expansion joints used in the device, the quality requirements in line with GB012, GB374 regulations, and shaped steel bridge expansion joints used (ie 16MN or Q345) comply with JT / T1591's. GQF-C-type bridge expansion [ bridge expansion joints] is to adapt to a new type of highway bridge construction bridge expansion joint device. GQF-C-type bridge expansion with the overall hot-rolled special steel 16Mn overcome uneven extrusion profiled steel straightness and collection size characteristics, GQF-C-type bridge expansion comprehensive technical performance and technical indicators have reached or exceeded the international advanced level, structure type and shaped steel rolling are the first domestic manufacturer of quality cd40-type bridge expansion joints may be, will become the standard recommended by the transportation industry Products] [bridge expansion joints GQF-C-type bridge expansion rubber seal in the middle of its technical requirements: chloroprene rubber (CR) and the temperature of the sealing device is suitable for stretching the rubber band is -25 ℃ - + 60 ℃ areas with natural rubber (NR) device with a rubber seal for temperature of -40 ℃ -. + 60 ℃] area [bridge expansion joints installed expansion joint device is adapted to the river and the route is not perpendicular to the direction of the bridge needs to be reinforced and the anchor displacement control box anchor bars and the horizontal displacement of the control box diagonally arranged for a variety of upcoming expansion volume 0 ~ 80mm telescopic device and MZL160 ~ 1200mm modulus telescopic device is tilted edge welded shaped beam, with its anchor bars angle side of the beam direction and the inclination of the bridge with the change.
