Plastering-free formwork construction method for cast-in-place pipe gallery bottom plate
The invention relates to a plastering-free formwork construction method for a cast-in-place pipe gallery bottom plate. The plastering-free formwork construction method comprises the following steps that S1, an outer side formwork and an inner side formwork are manufactured; s2, waterproof coiled material construction and waterproof protective layer construction are conducted, and plastic nails are pre-buried at the outer end of the waterproof protective layer; s3, steel bar engineering is constructed according to conventional procedures; s4, an outer side formwork and an inner side formwork are pre-spliced, and the upper portion of the outer side formwork and the upper portion of the inner side formwork are fixed through a square steel sheet with a reserved strip-shaped hole; s5, the plastic nails are knocked into the waterproof protection layer again through the nail holes, and binding wires penetrate through reserved wire grooves to bind the cement cushion blocks to the upper reinforcing steel bars on the lower portion of the inner side formwork; s6, concrete is poured; and S7, mold removal is conducted. The outer side of the lower portion of the cast-in-place pipe gallery bottom plate joint outer side formwork is manufactured to be in an arc shape, arc wiping before waterproof construction is merged into structure construction, the procedure is omitted, opposite-pull screws, steel pipe battens and the like do not need to be used, construction is easy, the construction cost is reduced, and the construction speed is high.
本发明涉及一种现浇管廊底板免抹灰模板施工方法，包括以下步骤：S1:制作外侧模板和内侧模板；S2:进行防水卷材施工，防水保护层施工，防水保护层上外端预埋塑料钉；S3:按常规工序施工钢筋工程；S4：预拼外侧模板和内侧模板，外侧模板与内侧模板的上部通过带预留条型孔的方形钢片固定；S5：再次将塑料钉通过钉孔敲入防水保护层中，内侧模板下部采用扎丝穿过预留线槽将水泥垫块绑扎于上部钢筋上；S6：浇筑混凝土；S7：进行拆模。本发明现浇管廊底板节点外侧模板的下部外侧制作成圆弧状，将防水施工前抹圆弧并入结构施工中，省去该道工序，且本发明不需要使用对拉螺杆、钢管木方等，施工简单，降低了施工成本，施工速度快。
