    FD-60型伸缩缝安装

    1、如要在先摊铺路面后装伸缩缝,为保证路面良好的平整度，应该先摊铺路面，然后开槽安装伸缩缝。摊铺路面之前，必须首先清理预留间隙并嵌填泡沫板，再用砂袋或级配砂石袋填实槽口。回填标高以控制沥青不会污染预埋钢筋为宜，目的在于防止摊铺设备压坏预埋钢筋，便于路面连续摊铺。

    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.
    2、桥面的切缝、清槽按预留的槽口宽度用切缝机对路面的油面层进行切缝。切缝时应注意保持路面切口完好，无啃边现象。切缝后及时清除槽内沥青混凝土及填料，凿毛槽口内混凝土表面。这一系列工序非常重要，它将影响混凝土的浇筑质量。
    2. The cutting seam and the cleaning groove of the bridge are slit with the cutting machine on the b of the reserved notch. Attention should be paid to maintaining good pavement incision and no undercut while cutting. After cutting, clean the asphalt concrete and packing in the slot, and then cut the concrete surface in the notch. This series of processes is very important, it will affect the quality of concrete pouring.

    3、在安装伸缩缝时,下缝前应认真检查槽内预埋钢筋，若发现裂缝或折断，位置不当或间隙过大，必须采取补救措施。要保证沿缝方向每米范围内至少有1根预埋钢筋与毛勒伸缩缝的锚环牢固焊接。应该认真检查XF型桥梁伸缩缝质量，若发现变形或两钢梁间距不一致时，应进行修整。必要时，还应根据安装时的环境温度调整毛勒伸缩缝的钢梁间距。应将XF型桥梁伸缩装置缓缓放入槽内，使缝中心线与实际预留缝中心线相重合，偏差不得超过10mm，同时使钢边梁内边保持垂直。XF型桥梁伸缩缝就位后，应根据纵、横坡和标高调整其钢梁顶面比相邻沥青混凝土路面低1～2mm，不得超出路面标高。

    3, when installing expansion joints, the lower slot should be carefully checked in the pre bded steel bar, if found cracks or broken, improper b or gap is too large, remedial measures must be taken. Make sure that at least 1 bded steel bars and the anchor ring of the expansion joint are firmly welded in the range of the direction of the seam along the seam. The quality of expansion joints of XF bridges should be checked carefully. If the debation or the spacing between the two steel beams is found to be inconsistent, they should be trimmed. When necessary, the spacing between the steel beams of the expansion joint shall be adjusted according to the environmental temperature at the time of installation. The XF type expansion device shall be put into the slot slowly, so that the center line of the joint coincides with the central line of the actual reserved slot, the deviation shall not exceed 10mm, and the inside edge of the steel edge beam shall be kept vertical. After the XF type expansion joint is in place, the top of the steel beam shall be adjusted according to the longitudinal, transverse slope and elevation. The top surface shall be 1 to 2mm lower than that of the adjacent asphalt concrete pavement and shall not exceed the elevation of the road surface.
    4、在焊接先点焊部分预埋钢筋和锚环钢筋，临时固定其位置。经检查符合质量要求后方可将锚环钢筋与预埋钢筋焊牢，之后，即可拆除XF型桥梁伸缩缝的装配夹具。
    4, in welding first spot welding part, pre bded steel bar and anchor ring steel bar, temporary fixed b. After inspection to meet the quality requirements before the anchor ring reinforcement and bded steel, welding, assembly fixture can be demolished XF type bridge expansion joint.
    5、对于立模、浇混凝土立模应注意模板密封，切忌水泥浆漏入支撑箱，影响支承部件和控制系统的正常工作。浇筑混凝土之前，在锚环内应插入一定数量纵向钢筋；在钢边梁水平肢上加铺一层钢筋网；在支撑箱底板上设置双层防震钢网。应采用低收缩、快硬、早强混凝土，其标号不得低于上部结构混凝土标号。特别注意锚板、锚环及横梁支撑箱下面的混凝土密实。在混凝土养护期内，禁止一切车辆通行。
    5, for bwork and concrete pouring bwork should pay attention to the template sealing, avoid cement slurry leak into the support box, affect the supporting parts and control system of normal work. Before pouring concrete, a certain amount of longitudinal reinforcement should be inserted into the anchor ring; a layer of reinforcing steel net is added to the horizontal edge of the steel edge beam; a double-layer shock proof steel net is arranged on the bottom plate of the support box. Low shrinkage, quick hardening and early strength concrete shall be adopted, and their grade shall not be lower than that of upper structure concrete. Pay special attention to the concrete density under the anchor plate, anchor ring and cross beam support box. During the maintenance period of the concrete, all vehicles are forbidden to pass.
    SGF120桥梁伸缩缝的产品特点如下：
    SGF120 bridge expansion joint products are as follows:
    1、该桥梁伸缩缝采用挤出成型的Q345（ASTM A709Grade50）型钢，强度高。型钢为齿型结构，增加了伸缩量，提高了行车平稳，适用于高速公路及城市道路的桥梁伸缩缝，并能较好地适应桥梁的纵向位移。

    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.

    2、此桥梁伸缩缝的伸缩量为0～120mm，介于80mm与160mm的伸缩量之间，避免使用伸缩缝的伸缩量为80mm的伸缩装置而造成行车不平稳，以及采用伸缩量160mm的伸缩缝而增加工程造价的问题。
    2, the expansion of the bridge expansion joint is 0 ~ 120mm, between the expansion amount between 80mm and 160mm, to avoid the use of expansion joint expansion caused by the unstable running as the expansion device of 80mm, and increase the project cost and the amount of expansion joint expansion problem 160mm.
    3、采用的锚固系统与GQF－MZLⅡ80相同，适用于各种梁端结构，其预留槽（包括铺装层）高度≥150mm。
    3, the anchor system and GQF MZL II 80, applicable to all kinds of beam structure, the slot (including pavement) height greater than 150mm.
    4、将W型氯丁橡胶伸缩密封条嵌入型钢内，防水、防尘性能佳。

    4, W type neoprene bescopic sealing strip bded in the steel, waterproof and dustproof perbance is good.
