Introduction angle joints and caulk the [compression] angle joints bridge expansion joints Such joints and the adjacent side of the deck, each in angle strengthen, its main purpose is to prevent the upper corner of the concrete blocks were shaken by road bad shock. Seam or hollow, or pouring asphalt and then to copper skin beneath the seal, to facilitate the water and prevent asphalt whereabouts. This type of expansion joint can be applied with a span longer RC, PC bridge and steel bridge. The maximum amount of stretching up to 5cm. [] Angle joints bridge expansion joints advantages:? Can Free the concrete bridge deck at a corner by the live load of impact damage. ? Construction easy. ? Structure are fairly simple, by improving enhanced wear layer overlying very good results. ? If sutural perfusion asphalt, plus copper under the skin can strengthen the role of waterproof. [] Angle joints bridge expansion joints Disadvantages:? Purports construction and concrete planing angle is not easy, it is easy to cause the vehicle jump bridge expansion joints, welding and shock angle from concrete, resulting in poor durability. However, after improvement, the angle between the post and plate can improve this shortcoming. ? Case takes a long time to repair the closed traffic. ? Easy to rust. The main material] [bridge expansion joints compression compression caulk caulk can withstand an elastic material is compressed by the elastic material may be compressed and pressed into the cracks of the original opening, this open seam edge with a viscosity surface coatings gqf-e40 bridge stretching devices, thus compressing sewn seam can then be compressed into the opening tightly affixed to the original open seam of the deck edge. Such joints using a rubber synthetic chemicals as expansion joints. [Bridge expansion joints] concrete curing concrete pouring is complete, timely geotextile covering health, during the health of not less than seven days. After the concrete strength more than 50% of the design strength, install the rubber seal, must serve as a template of foam board seam prior to installation, fiberboard, concrete lumps all plasma leakage after a clean dig gqf-f60 bridge stretching devices, embedded in rubber Article. [Bridge expansion joints] Construction Notes 1) Notify the construction site before the expansion joints and technical personnel, technical personnel to be post-mortem consent before construction site supervision. 2) slotted slit completed clean up debris inside seam, ensure clean seam to be constructed. 3) Install] [bridge expansion joints embedded parts before checking whether the specification is complete, broken, bent embedded part of the adjustment righting gqf-e80 bridge stretching devices, before construction of the padded embedded parts missing. 4) The gap width and stretching between the ends of the upper structure of the disposal of equipment and installation of a predetermined width are installed with proper temperature, and in accordance with the provisions of the drawings. Expansion joints installed in the fixture control joints manufacturer, to install a temperature in the range of 10 ± 5 ℃. When the expansion joint installation temperature differs with the drawings, according to the comprehensive calculation span, continuous deck length, the installation temperature, etc., and the procedures to be adjusted after the confirmation of the installation parameters. 5)] [bridge expansion joints with high-quality welding electrodes one by one. First welding welding a top surface, and then welded side, and finally welding the bottom surface, and in a timely manner to the hierarchical welding welding slag removal, after the welding portable grinder polished top surface. Weld length not less than specifications.
