Support mechanism single slit type bridge expansion joint device from the direction parallel to the bridge joints, using thick steel plate welded longitudinal steel beams (currently used in the overall shape of profiled steel, referred stringer) and parallel to the bridge axis transverse support steel beams (referred to as beam) formed. The side sill and the side sill and the side is divided into different forms of cross-section of the stringer. For single stitch, located only side rails, no stringers and beams in its construction layout shown in Figure 5-1. Expansion joint support mechanism multi-slit apparatus shown in Figure 5-2. J-75 multi-slotted expansion joint device D160 bridge expansion joints installed on the need to construct, in Figure 5-3 stringer to contact arrangement connected with the crossbar. That is the number of beams in each group and the number of roots equal stringers. Repair damaged telescopic device methods vary according to the size of each form of good roads and bridges flux structure is different, but generally more difficult to repair or replace the GQF-e60 bridge expansion joints, especially the highway, forms of transportation when needed to implement large and bridge structures differ repair traffic control, practice shows that it was reasonable and perfect telescopic device even when the design and construction are convinced that after completion of the project, once open traffic. Early examples of defects that appear damaged, there are many children, therefore, the bridge expansion device, design and the construction is not a little defective. For this bridge expansion joints, causes of defects and damage telescopic device ever constructed a careful and detailed summary, branch type and necessary. As China's highways and urban roads circle D40 bridge expansion joints manufacturers, competing traffic volume and heavy vehicles, early and mid-stage phenomenon. Most damage has rendered the state.
