 [Bridge expansion joints bridge expansion joints] [] construction methods in the design of the bridge structure highway bridge expansion joints quality sales, usually between two beams side of the bridge, set between the end of the beam joints and abutments. Its role is to regulate the displacement is connected to the upper structure and physical properties of the vehicle load and environmental characteristics of building materials caused by the bridge between. In this paper, the method of construction of bridge expansion joints in detail. ] [Bridge expansion joints in the bridge structure design, bridge expansion joints are usually between two beams side of the bridge abutment and a telescopic device with 5 holes for each i set atop Union Pier, which is part of the bridge structure, Its role is to regulate the displacement and the upper structure linking the physical properties of the upper structure of the vehicle load and environmental characteristics of building materials caused by the bridge and between the deck and the road, bridge and bridge stretching between freedom guaranteed by Good convergence. [] Is the weak position of bridge expansion joints of the bridge structure, is to withstand the maximum power load of accessories products offer highway bridge expansion joints, bridge minor irregularities will make it withstand great impact, so the joints of construction is highway bridge construction an extremely important project, its construction quality is good or bad, whether scientific, timely maintenance, will directly affect the future quality of driving stability, comfort, security, and service and bridges life. Bridge expansion joints [1] construction characteristics, flexibility, and scalability can be good. 2, good wear resistance, corrosion resistance, anti-slide, waterproof, anti-aging properties. 3, vibration, no noise. 4, long life Guangrun production concession highway bridge expansion joints, easy maintenance. 5, the construction and ease of installation and maintenance. [Bridge] telescopic joints earthquake displacement changes make structures earthquake occurred on the bridge expansion joints [affect] the displacement device is more complex, it is hard to grasp, in the design of scalable apparatus generally not be considered; however, if reliable Data can calculate the earthquake on the bridge pier sinking, rotation, horizontal movement and tilt amount, given consideration in the design of course better. [Bridge] longitudinal joints affect longitudinal displacement of a large bridge, usually bearing construction activity made the level of highway bridge expansion joints, so when the displacement of the bearing surface creates a vertical difference (Δd) its value is multiplied by the longitudinal horizontal displacement (tgθ), in the case of smaller displacement can not be considered, but in a combination of steel bridge for large and longitudinal displacement is also large, the design of the bridge expansion joints [device] The form should be taken seriously. [Bridge expansion joints]. Displacement curve of the bridge and the bridge of the bridge of the bridge and curve support in the event of displacement △ L direction of movement when there change in displacement △ S and the vertical direction of the bridge end line to end line direction of the bridge Bit △ d: △ d = △ L sinθ △ S = △ L cosθ where: θ- tilt angle; △ L- amount of stretching. The direction of movement along the bearing displacement △ L called joints, the bridge perpendicular to the displacement △ d-line is called the beam end joints. Because the bridge parallel to the displacement of the leaving end line △ S] [bridge expansion joints. Device in the plane torsion, shear stress, must be taken in the design. Meanwhile, attention should be paid the effects of different forms of constraints and pier bearing produced.
