Construction method of large-area floor of basement
The invention discloses a construction method of a large-area floor of a basement. The method comprises the steps that firstly, the construction floor is measured and paid off, and the floor elevationand the formwork position are determined and positioned; a floor foundation base layer is cleaned, a slope making ash cake is placed, the surface of the foundation base layer is coated with neat cement paste, then a slope making layer is poured according to the slope making ash cake, a drainage plate is laid, a floor formwork is erected and reinforced, a combined formwork of a wood plate and angle steel is adopted as the formwork, and fixed connection is conducted through a full-thread screw; a prefabricated ash cake is arranged on the drainage plate according to the elevation, pouring construction is conducted according to bin dividing and bin jumping, and vibrating and compacting are conducted; a steel bar mesh is placed on the surface of concrete, and the steel bar mesh is settled in the leveling process; and a trowelling machine is adopted for large-area floor smoothing construction, after concrete curing, expansion joints and construction joints are cut, joint filling materials are filled, and curing is conducted after concrete final setting. According to the method, floor cracks are effectively avoided, surface layer water accumulation caused by water seepage is eradicated,the surface of a concrete surface layer is flat and smooth, and the construction quality of the floor is improved.
本发明公开了一种地下室大面积地坪的施工方法，本方法首先对施工地坪进行测量放线，确定地坪标高及模板位置定位；清理地坪地基基层，放置找坡灰饼，地基基层表面涂刷素水泥浆后根据找坡灰饼浇筑找坡层，铺设疏水板，地坪模板支设及加固，模板采用木板与角钢的组合模板，并采用全丝螺杆进行固定连接，在疏水板上根据标高设置预制灰饼，根据分仓跳仓进行浇筑施工并振捣密实，混凝土表面摆放钢筋网片，并在整平过程钢筋网片沉降，采用抹光机进行大面积地坪收光施工，混凝土养护后切割伸缩缝和施工缝并填充填缝材料，混凝土终凝后养护。本方法有效避免地坪裂缝的产生，杜绝渗水导致的面层积水，且确保混凝土面层表面平整光滑，提高地坪的施工质量。
