. [] Types of bridge expansion joints bridge expansion joints [currently] Several types are as follows: 1. open seam along the open seam structure is open, without any closed joint compound. The openings of the bridge deck is usually concrete, but may also have been reinforced steel structure. Advantages strengthen steel structures can block some of the waste in its opening fell into the cracks, also indirect protection of concrete bridge deck joints are opening. The openings on the biggest drawback is its water-blocking function, easy-board deck water along the open seam down the river, so that structures under the bridge deck deterioration has accelerated bundle interference. Another disadvantage is that the open seam usually apply only to vertical expansion, therefore, for the purposes of the new bridge, unless very short span of bridge expansion joints, should not be used otherwise. 2. Blind Stitch] [bridge expansion joints. Such joints] [bridge expansion joints wear layer is disposed on the upper half position, and therefore the adjacent deck (or abutment) intermediate steel without any additional devices or artificial rubber, only the upper part of the wear layer cut into joints for expansion purposes. Such joints are usually only useful in the smaller amount of traffic looking to buy a bridge expansion joints Guangrun! GB, and the amount of stretching in the short span bridges 5mm or less. Blind Stitch] [bridge expansion joints advantages:? Due to continuous wear layer and road laying, driving more comfortable, will not have a severe shock. ? Simple structure, easy construction of bridge expansion joints Guizhou good quality excellent price! Low cost. ? When repairing damaged easily. [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 elastic rubber bridge expansion joints Yunnan direct discount prices!, 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 a good performance and easy to use shock-absorbing cushion rubber sealing material to do with the strength of good performance shaped steel combination, in the case of a large amount of displacement of the vehicle can withstand the load-supporting several types of mold (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 TST gravel can be used within the elastic expansion joint device, a special elastic-plastic material is heated to melt TST, poured through the rubble cleaning heating, namely the formation of elastic joints TST gravel, crushed stone to support the vehicle load, TST elastic-plastic body at a 25 ℃ ~ 60 ℃ conditions to meet the requirements of the amount of stretch.
