Army bridge GQF-MZL Modular bridge expansion joints, GQF-MZL Modular bridge expansion joints is a Modular bridge expansion joint device by the side beams, beams, beams and linked institutions, and for stretching the amount 80mm-1200mm of large and medium span bridges. Heavy use of bridge expansion joints. Modular expansion joints, expansion joints 160, 240 joints to adapt to the development trend of China's transportation industry, the product selection, the structure in the original first generation of products based on a major breakthrough and enhanced. 160 240 model is the expansion joints, Modular expansion joints, expansion joints 160, 240 joints using load-bearing structure and the displacement control system apart, when the two forces interfering, clear division of labor, so that not only guarantee the security forces, and to achieve uniformity of displacement, so that all the beams in a displacement control box are supported on the same traditional practices of a vertical beam, so that a large amount of displacement of the telescopic device is very advantageous to reduce the number of beams, so that the displacement volume is reduced to the control box minimum, saving steel. Fourth, expansion joints Installation Notes (1) the length of the telescopic device due to transportation restrictions, can be segmented manufacturing, field splicing. Stored at the site of the telescopic device should be placed in parallel, not cross stacking to prevent deformation. (2) at the factory, only connect fixtures designed for easy transport, the gap is not a given location. When the telescopic device installation, should only be carried out under the supervision of engineers recognized. As specified on the design documents to file under the bridge design is based. (3) Modular expansion joints, expansion joints 160, 240 joints before hoisting concrete tank should be set aside to fight hair, cleaned. When the value of a telescopic device installation width along the bridge to the deal said on gap expansion joints, and its top surface elevation and design elevation anastomosis pad level, and then put through a coupling level value to steel, telescopic device The anchor bars and weld steel beams embedded on both sides (try to increase the weld and weld length, to extend the life telescopic device), relax fixtures to free expansion, this time stretching device has entered the state. (4) After completion of the above steps, installing the necessary template to prevent the inflow of mortar joints, and then carefully washed with water. Reserved slots in the concrete pouring of more than concrete C50. Pouring concrete should take the necessary measures, vibrating compaction.
