Bridge expansion joint installed structure repair quickly with high polymer material

Polymer structure of rapid repairing materials polymer structure of rapid repair materials manufacturer polymer structure of rapid repair materials price of bridge expansion joint device specification, performance, should comply with the design requirements, and shall comply with current industry standards ( Highway Bridges and BJT/T327) The provisions of the. Telescopic device installed reserved slot size should comply with the regulations of design, the location of the fault of solid steel should be accurate. Stretching device before installation should be reserved slot mouth clean. Bridge expansion joint device should be in after the completion of the bridge deck pavement, take the way of the slot for installation; When the first installation of bridge deck again ways, effective measures should be taken to properly protect installed telescopic device. Bridge expansion joint device before the installation, should be in accordance with the actual temperature to adjust its orientation of the field values. After installing fixed, on both sides of the transition section of high polymer rapid architecture repair material ( The bridge expansion joint mortar) Appropriate under the joint telescopic open casting, build the measures should be taken to prevent have fixed component shift, and should be timely maintenance after pouring, curing time should be not less than 7 d. Comb plate telescopic device installation, measures should be taken to prevent comb uneven, the phenomenon such as distortion and deformation, and to cope with the comb tooth clearance error control, when the highest temperature, comb the lateral clearance shall be not less than 5 mm, tooth plate clearance shall be not less than 15 mmo rubber expansion device installation shall meet the following requirements 1 bridge expansion joint before installation should check reserved slot size and reinforcement of bridge deck ends, confirmed that can be flawless before the installation. Using embedded rubber expansion after the body, should be rapidly architecture in the bridge deck polymer repair materials ( The bridge expansion joint mortar) Complete drying shrinkage and creep are most again after installation. 2 bridge expansion joint before installation should be reserved slot slot concrete surface is clean, and the waterproof glue stick wood materials. Should be based on the temperature and the seam width, make the necessary adjustments, then telescopic device installed in place, and after installation should make its in the compression state. 3 shall be computed according to the installation environment temperature setting expansion device and the width of the template and bolt spacing, will strengthen reinforced with bolt welding in place, then pouring polymer in the transitional period of rapid architecture repair material ( The bridge expansion joint mortar) And beverage curing. Bolt hole perfusion to the bridge expansion joint device corrosion after the seam an agent, should cover blocks in a timely manner.
