GQF-L型桥梁伸缩缝
GQF-L型桥梁伸缩装置是采用热轧整体成型的异型钢材设计的桥梁伸缩装置。该装置适用于伸缩量80mm以下的桥梁接缝。
The GQF-L type bridge expansion device is a bridge expansion device designed with the special-shaped steel formed by hot rolling. The device is suitable for bridge joints under the expansion of 80mm.
对于C、F、E、Z、L型桥梁伸缩缝都是公路桥梁专用的伸缩装置的一种，它由一组钢质边梁及锚固件组成加一条整长的橡胶密封条组成。在伸缩装置的钢质边梁外侧的锚固件，与梁端预埋钢筋相焊接，浇筑高强度混凝土过渡段后，同梁体连结。
GQF-L型伸缩缝具有连结可靠，与桥面接合平顺，密封止水、伸缩灵活，行车平稳，使用寿命长的特点。在接缝处的桥面防水层仍应妥善铺设，防止雨水侵蚀承重结构。如采用敞口式的桥梁伸缩缝，还应考虑便于清除污物，并在缝下设置截水和引水装置，使积水排出桥外。适用于伸缩量为40mm、60mm 和 80mm 的桥梁。
For C， F， E， Z and L bridge expansion joints， they are all kinds of special expansion devices for highway bridges. They consist of a group of steel side beams and anchors， and a whole long rubber sealing strip. The anchorage of the steel side of the steel side beam of the telescopic device is welded with the preburied steel bar at the end of the beam， and is connected to the same beam after the high strength concrete transition section is poured. The GQF-L type expansion joint has the characteristics of reliable connection， smooth connecting with the bridge surface， sealing and sealing water， flexible and flexible， smooth running and long service life. The waterproof layer of the bridge surface at the joint should still be properly laid to prevent rainwater from eroding the load-bearing structure. If an open bridge expansion joint is used， the removal of dirt should also be considered， and the water and water diversion devices are set up under the seams so that the water can be discharged out of the bridge. It is suitable for bridges with 40mm， 60mm and 80mm.
