伸缩缝按照性能及安装方法可以分为:GQF-C型、GQF-Z型、GQF-L型、GQF-F型、其中GQF-MZL型数模式桥梁伸缩缝装置,是采用热轧整体成型的异型钢材设计的桥梁伸缩缝装置. GQF-C型、GQF-Z型、GQF-L型、GQF-F型伸缩缝装置适用于伸缩量80mm以下的的桥梁接缝, GQF-MZL型伸缩缝装置是由边梁、中梁、横梁和连动机构组成的模数式桥梁伸缩缝装置,适用于伸缩量80mm-1200mm的大中跨度桥梁.
伸缩缝由一条整长的橡胶密封条,一组刚质边梁及锚固件组成。钢质边梁内侧带有能固定橡胶密封条的沟槽。焊固在钢梁外侧的锚固件,与梁端预埋钢筋相焊接,浇筑度混凝土过渡后,同梁体连接可靠,具有与桥面接合平顺,密封止水、伸缩灵活,行车平稳,使用寿命长的特点。使用于伸缩量0~80mm的桥梁。
The expansion joint is made up of a long rubber sealing strip, a set of rigid side beams and anchor. The inner side of the steel edge beam has a groove that can fix the rubber sealing strip. Welded on the outside of the anchor beam, and beam end embedded steel welding, casting of high strength concrete beams after the transition, with reliable connection, with the deck water sealing, smooth engagement, scalable and flexible, stable running, long service life. Bridge used for expansion of 0 ~ 80mm.
单组式伸缩缝主要材料:钢质边梁:采用16Mn的钢轧制,部面呈c形。橡胶密封条:采用氯丁橡胶制造,具有良好的耐老化、耐挠性能。
