Contact Mr.Tang 24-hour hotline telephone 15333180470 0318-5821892 GQF-C type, GQF-Z type, GQF-L-type matters GQF-F-type storage and installation should pay attention to pay attention to the steps as follows: 1, as will be installed prior Pavement joints, in order to ensure good pavement smoothness, paving the road should be, then slotted the installation of expansion joints. Prior to paving the road, you must first clean up the gap and filling them aside foam board, then sand bags or bags graded gravel infill notch. Backfill elevation to control the pitch will not pollute the embedded steel is appropriate, the purpose is to prevent the spreading device embedded steel crushed to facilitate continuous road paving. 2, deck slit, slot by slot clear width reserved by cutting and sewing machine oil on the road surface is slit. Kerf cut should keep the road in good condition, no bite side of the phenomenon. After the timely removal of asphalt concrete slit slot and filler, chisel concrete surface of the inner hair notch. This series of process is very important, it will affect the quality of concrete pouring. 3, the installation of expansion joints, should be carefully checked before the next slot embedded steel joints, cracks or broken if found improper position or the gap is too large, must take remedial measures. To ensure the seam along at least one direction and Maurer embedded steel anchor ring is firmly welded joints per meter range. Should carefully check the XF-type bridge expansion joints quality, if found deformed or two girder spacing is inconsistent and should be trimmed. When necessary, they should adjust Expansion Joints girder spacing according to the ambient temperature of the installation. XF-type bridge expansion should slowly into the tank, so that the actual reservation center line and sewing the seam centerline coincides deviation of not more than 10mm, while the steel side sill inner side vertical. After the XF-type bridge expansion joints in place, the top surface of the steel beam should be adjusted according to its longitudinal and transverse slope and elevation lower than the adjacent asphalt concrete pavement 1 ~ 2mm, shall not exceed the pavement elevation. 4, in the first spot-welding and anchor ring portion embedded steel reinforcement, temporary fix its position. The inspection meet quality requirements only after the anchor ring reinforcement and embedded steel weld, then, can be removed XF-type bridge expansion joint assembly jig. 5, for the formwork, pouring concrete formwork should note template sealed grout should not leak into the support box, affecting the normal operation of the support member and the control system. Before pouring the concrete in the anchor ring should be inserted into a number of longitudinal bars; on the steel side beam horizontal limb add a layer of steel mesh; bottom plate is provided in support double shock stencil. Use a low-shrinkage, fast hard, early strength concrete, the label can not be lower than the upper structure of concrete grade. Special attention anchor plate, anchor ring and beamed compacting concrete box below. In concrete curing period, the ban on all vehicular traffic.
