Construction method] [bridge expansion joints] [bridge expansion joints in the bridge structure design, usually between the two ends of the bridge girder, 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 coupling cd60-type bridge expansion joint displacement and physical properties of the upper structure of the upper structure of the vehicle load and environmental characteristics of building materials caused by the bridge and between the 50-year warranty, guaranteed by free expansion bridge and pavement, Good convergence between the deck and the deck. [] Is the weak position of bridge expansion joints of the bridge structure, is to withstand the maximum power load of accessories, deck small irregularities will make it withstand great impact, so the joints of construction is the construction of a highway bridge extremely important project items, its construction quality is good or bad, whether scientific, timely maintenance, will directly affect the future quality of service and traffic smooth service life, comfort, security, and bridges. 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, easy maintenance. 5, the construction and ease of installation and maintenance. [Bridge] combination shear joints (plate) rubber expansion means the device is the use of a variety of different cross-sectional shape of the rubber band as a caulking material telescopic device. Because manufacturers of rubber bridge expansion joints flexible range, easy to paste, but also to meet the requirements of the deformation and have waterproof function. Thus, in the domestic and foreign bridge engineering has been widely used. [Bridge expansion joints] modulus telescopic device supporting plate rubber products in this category telescopic device, it is difficult to meet the requirements of a large amount of displacement; steel type of telescopic device, it is difficult to achieve watertight seal, and likely to cause the vehicle impact, the impact driving of the vehicle. Therefore, there has been the use of shock-absorbing cushioning performance is good and easy to do the sealing rubber material, and the strength of the combination of high performance and reliable good shaped steel bridge expansion joints quality Guangdong, in the case of a large displacement of the number of vehicles can withstand all kinds of mold load Bearing (Modular) bridge expansion series. [Bridge expansion joints] telescopic device elastomer elastomer telescopic device into zinc metal joints and elastic joints TST gravel, elastomer telescopic device is a simple expansion joint device for small and medium span bridges, while stretching the amount at the 20mm-40mm can be used within the elastic expansion joint device gravel TST bridge expansion joints, elastic-plastic material is specially TST after heating and melting, heating of gravel poured cleaned, that the formation of elastic joints TST gravel gravel to support the vehicle load, TST elastic-plastic body at a 25 ℃ ~ 60 ℃ conditions to meet the requirements of the amount of stretch.
