Construction method of continuous beam 0 # block in hanging basket cantilever construction
The invention belongs to the technical field of bridge construction, and discloses a construction method of a continuous beam 0 # block in hanging basket cantilever construction. The method comprises the following steps that S1, steel pipe stand columns are arranged on a bearing platform, and distribution beams are installed on the steel pipe stand columns; and S2, laying a bottom template of a 0 # block on the distributive girder. And S3, the pre-embedded plate provided with the climbing cone is welded to the top end of the steel pipe stand column, so that the pre-embedded plate blocks the preformed hole in the bottom formwork. And S4, connecting pieces are arranged in the steel pipe stand columns, and concrete is poured into the steel pipe stand columns. And S5, side formworks and a top formwork are laid, and concrete is poured to form 0 # blocks. And S6, before the mid-span closure section is poured, the steel pipe stand columns are cut, stress bolts of the climbing cones are screwed out so that the steel pipe stand columns and the embedded plates can be dismantled, and meanwhile cement mortar is used for blocking holes left in the 0 # block after the climbing cones are dismantled. According to the method, concrete does not need to be poured again when the steel pipe stand column is dismantled, cost is saved on the basis of guaranteeing the appearance of the continuous beam, and construction efficiency is high.
本发明属于桥梁施工技术领域，公开了一种挂篮悬臂施工中连续梁0#块的施工方法。该方法包括以下步骤：S1、在承台上布置钢管立柱，并在钢管立柱上安装分配梁；S2、在分配梁上铺设0#块的底模板。S3、将安装有爬锥的预埋板焊接于钢管立柱的顶端，以使预埋板封堵底模板上的预留孔。S4、在钢管立柱内布置连接件，并向钢管立柱内浇筑混凝土。S5、铺设侧模板和顶模板，并浇筑混凝土以形成0#块。S6、中跨合拢段浇筑前，切割钢管立柱，并拧出爬锥的受力螺栓，以拆除钢管立柱和预埋板，同时使用水泥砂浆封堵拆除爬锥后在0#块上留下的孔洞。该方法在拆除钢管立柱时无需重新浇筑混凝土，在保证连续梁外观的基础上节省成本，施工效率高。
