GQF-L型橋梁伸縮縫

GQF-L型橋梁伸縮縫

GQF-L型橋梁伸縮裝置是采用熱軋整體成型的異型鋼材設(shè)計(jì)的橋梁伸縮裝置。該裝置適用于伸縮量80mm以下的橋梁接縫。

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.

對(duì)于C、F、E、Z、L型橋梁伸縮縫都是公路橋梁專用的伸縮裝置的一種，它由一組鋼質(zhì)邊梁及錨固件組成加一條整長(zhǎng)的橡膠密封條組成。在伸縮裝置的鋼質(zhì)邊梁外側(cè)的錨固件，與梁端預(yù)埋鋼筋相焊接，澆筑高強(qiáng)度混凝土過(guò)渡段后，同梁體連結(jié)。

GQF-L型伸縮縫具有連結(jié)可靠，與橋面接合平順，密封止水、伸縮靈活，行車平穩(wěn)，使用壽命長(zhǎng)的特點(diǎn)。在接縫處的橋面防水層仍應(yīng)妥善鋪設(shè)，防止雨水侵蝕承重結(jié)構(gòu)。如采用敞口式的橋梁伸縮縫，還應(yīng)考慮便于清除污物，并在縫下設(shè)置截水和引水裝置，使積水排出橋外。適用于伸縮量為40mm、60mm 和 80mm 的橋梁。

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.
