Bridge expansion joint devices are divided into single-group bridge expansion joints and modular multi-group bridge expansion joints gravel elastic expansion joints plate type rubber expansion joint combinations Rubber expansion joints. Single-group bridge expansion joints are also called expansion joints, and the product series is divided into five types of special-shaped steel multi-group modular expansion joints, which are suitable for large highway bridges. Expansion joint
Smooth driving, low cost, good waterproof performance, and no tripping.
Set out according to the width of the expansion joint, and pay attention to cutting asymmetrically along the center line of the beam joint. Dig and clear away debris. The excavation depth should be at least . Fixing bolt positioning. Use the bolt hole combination template for setting out and positioning, and the screw position error. When drilling holes, internal structures of the beam, such as prestressed pipe steel bars, etc., must not be touched. The transition bottom steel grid is tied, the formwork is erected, and steel fiber concrete is poured. The elevation and flatness of the top surface must be strictly controlled, consistent with the longitudinal form slope of the bridge deck, and its flatness should be. Distribute steel bars within the binding transition section. Pour over section loaded steel fiber concrete. Install the water-stop neoprene sheet stainless steel plate and toothed plate and tighten them with nuts. In order to prevent the screw and nut from loosening, the threads must be coated with anti-loosening glue, and the screw and nut surfaces must be fixed with a small amount of spot welding. Finally, waterproof and anti-loosening epoxy resin must be poured into the screw holes. Concrete should be watered and maintained, and it should be protected from freezing and moisturizing in winter.
Expansion joints can be divided into types according to their performance and installation methods.
The medium-sized model bridge expansion joint device is a bridge expansion joint device designed using hot-rolled integrally formed special-shaped steel. The type expansion joint device is suitable for bridge joints with less than the expansion amount. The type expansion joint device is a modular bridge expansion joint device composed of side beams, middle beams, cross beams and linkage mechanisms. It is suitable for large and medium-sized expansion joints. span bridge.
