[Species] bridge expansion joints: Current, for bridge expansion joints generally have docking, steel bearing type, the combination of shear (plate), and the elastic modulus-bearing device. [1] bridge expansion joints, butt joints butt joints means more different structural forms and its mechanical characteristics can be divided into packing and embedded solid butt butt-type two. Butt telescopic device is packed asphalt, wood, oakum, rubber and other materials filling the gap, stretching the body in any case a state of compression. Such telescopic device for stretching the amount of general on 40mm or less conventional engineering, but is now rare. Docking embedded solid expansion joint device using different forms of steel members of different shapes rubber strip (band) embedded firmly fixed, and the rubber strip (band) to absorb the deformation of tension and compression deformation of the beam, which can be in the body by stretching overpressure condition. Also in tension. [] Steel bridge expansion joints supporting telescopic device when the stretching deformation of the bridge over 50mm, often with steel telescopic device. The telescopic device when the vehicle travels often due to the end of the beam generated by the rotation or deflection slap effect, noise, and easy to make structural damage. Therefore, with a bolt requires the use of spring means to fix the slide plate to reduce the rattling and noise, D40 bridge expansion joints, the joints of the structure is relatively complicated. [Bridge expansion joints bridge expansion joints] we often referred to as the joints, or bridge expansion. Bridge expansion joints need to structure, shape, length, etc. different bridge design, D40 bridge expansion joints portfolio, so every seat highway bridge expansion joints must choose different products to eliminate temperature, load on the bridge component damage. Materials and uses can be divided by expansion joints used: Modular bridge expansion joints and KS TST thermoplastic elastomer joints and expansion joints. [] Bridge expansion joints fill material and maintenance Filling material: According to the construction requirements, prior to construction, the upper joints should be first with stickers pasted, pouring material can be carried out, according to previously when pouring concrete pouring Methods for controlling the flatness (schematic after packing) below. [Bridge expansion joints] conservation: the use of soft, quick-curing epoxy resin (E2410 configuration mortar), setting speed, high early strength. After two hours the filled nature conservation can open traffic. [Bridge expansion joints] Note: [] Bump at Bridge Expansion, modulus D40 bridge expansion joints, which is the installation elevation and expansion joint on both sides of the road caused by elevation differences, should be strict process control, control joints flatness place to ensure that the expansion joint on both sides of the road surface elevation consistent with or slightly below the level on both sides of the road. [] Bridge expansion joint device is a part of the highway bridge construction, D40 bridge expansion joints width, the most commonly used types are MAURER joints, teeth mouth steel joints, rubber joints plate, U-type zinc metal, TST crushed stone projectile abbreviated form , its role is to regulate the displacement and the upper structure coupling the upper structure due to external temperature changes, concrete creep and drying shrinkage of concrete caused among other factors between. It also directly bear the repeated impact load wheels, a bridge structure most likely the site of the destruction. [] After the destruction of the bridge expansion joints seams sink, convergence at road damage, which appears high and low level, causing the vehicle generated by jumping, so board staff discomfort and even lead to accidents, the impact of the highway bridge normal operations. Plate D40 bridge expansion joints, D40 bridge expansion joints, produced by Guangrun-Engineering Rubber Co., Ltd. Hengshui. Hengshui-Engineering Rubber Co., Ltd.
