] [Bridge expansion joints installed rubber and quality control of steel fiber reinforced concrete pouring: beam positioning and laying pavement after anchoring steel, secondary tank cleaning up garbage, with high pressure water rinse and plugging the gap, after acceptance by the Commissioner, steel fiber reinforced concrete before pouring, pouring process should always check slump concrete mix meets the requirements to ensure the quality of concrete just fiber, concrete must be poured dense, smooth, no cellular flatness within 0-2mm range and a pouring, ensure the integrity, concrete vibrators vibrators should be used on both sides of the synchronization method to pan syrup, until no more air bubbles and ensure vibration compacting, for some corners of the place, with particular attention to vibration compacting concrete sex, after scraping rod vibration compacting concrete highway bridge expansion joints surface evenness Hebei large favorably, the general flatness should be controlled below the surface elevation of 2mm. Health: The initial setting of concrete watering regimen should be covered with a sack on the surface of the concrete to keep moist. Curing time is not less than 15d, [during] the bridge expansion joints should be someone to traffic control and health, good protection or closures, set up instructions from both sides of the bridge, warning signs, prohibited vehicles and pedestrians, bridge expansion joints to ensure [] After the device on both sides of the concrete strength to meet the design requirements in order to open traffic. Install rubber: After After health, concrete design strength of 50% before installing rubber. [QC] bridge expansion joints bridge expansion joints [] the construction process, the construction of the slit, slot, steel installation, pouring concrete and other procedures shall be carefully self-test and sampling, before entering the post-acceptance under a process 160 factory direct bridge expansion joints, while the steel installation, pouring concrete and other important processes are to control the entire process. [Bridge] telescopic steel expansion joints used in the device, the quality requirements in line with GB012, GB374 regulations, and shaped steel used (ie 16MN or Q345) comply with JT / T1591's. GQF-C-type bridge expansion joints [bridge ] 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 of bridge expansion joints, 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 a national initiative, will become the transportation industry standard recommended products. [bridge expansion joints] GQF intermediate -C type bridge expansion rubber seal its technical requirements: chloroprene rubber (CR) rubber seal with telescopic device suitable temperature is -25 ℃ - + 60 ℃ areas with natural rubber (NR) sealing rubber band. device is suitable for a temperature of -40 ℃ -. + 60 ℃ area [] to install expansion joints bridge expansion joint device is adapted to the river and the route is not perpendicular to the direction of the bridge steel bridge expansion joint products are exported to the need, you can anchor bars and displacement control box diagonal layout, anchor bars and the horizontal displacement of the control box is about stretching the amount of 0 ~ 80mm telescopic device and various MZL160 ~ 1200mm modulus telescopic device is tilted beam welding in the profiled edge, its anchor bars with edge Beam angle of inclination of the bridge with the direction change.
