FD-60型伸縮縫安裝
1、如要在先攤鋪路面后裝伸縮縫,為保證路面良好的平整度,應(yīng)該先攤鋪路面,然后開槽安裝伸縮縫。攤鋪路面之前,必須首先清理預(yù)留間隙并嵌填泡沫板,再用砂袋或級配砂石袋填實槽口?;靥顦烁咭钥刂茷r青不會污染預(yù)埋鋼筋為宜,目的在于防止攤鋪設(shè)備壓壞預(yù)埋鋼筋,便于路面連續(xù)攤鋪。
1, if it is necessary to spread the road before installing expansion joints, in order to ensure a good level of pavement, it should be paved pavement, and then slotted installation expansion joints. Before paving the road, must first b the reserved space and filled with sand filled foam board, or graded sand gravel bag slot. In order to control the elevation of backfill will not pollute the asphalt and pre buried steel should be designed to prevent spreading equipment for crushing and pre buried steel, continuous pavement paving.3、在安裝伸縮縫時,下縫前應(yīng)認真檢查槽內(nèi)預(yù)埋鋼筋,若發(fā)現(xiàn)裂縫或折斷,位置不當或間隙過大,必須采取補救措施。要保證沿縫方向每米范圍內(nèi)至少有1根預(yù)埋鋼筋與毛勒伸縮縫的錨環(huán)牢固焊接。應(yīng)該認真檢查XF型橋梁伸縮縫質(zhì)量,若發(fā)現(xiàn)變形或兩鋼梁間距不一致時,應(yīng)進行修整。必要時,還應(yīng)根據(jù)安裝時的環(huán)境溫度調(diào)整毛勒伸縮縫的鋼梁間距。應(yīng)將XF型橋梁伸縮裝置緩緩放入槽內(nèi),使縫中心線與實際預(yù)留縫中心線相重合,偏差不得超過10mm,同時使鋼邊梁內(nèi)邊保持垂直。XF型橋梁伸縮縫就位后,應(yīng)根據(jù)縱、橫坡和標高調(diào)整其鋼梁頂面比相鄰瀝青混凝土路面低1~2mm,不得超出路面標高。

1. The expansion joint of the bridge is made of extruded Q345 (ASTM, A709Grade50) steel with high strength. The section steel is a tooth type structure, which increases the expansion amount and improves the running stability. The utility model is suitable for the expansion joint of the highway and the urban road, and can well adapt to the longitudinal displacement of the bridge.
