我单位在某厂一座200m~3钢筋混凝土圆形贮水池施工中,为节约木材,采用普通钢管脚手杆作模板内支撑,取得了较好的效果。该水池内径9m,内高3.5m,壁厚12cm,底板、顶盖厚10cm。立筋φ6、8、10,间距13～26cm。混凝土200号(B_8),池内抹20mm厚1∶2水泥砂浆。因水池壁较薄,为确保工程质量,采取池壁与底板一次支模、浇灌混凝土的施工方案。施工缝设于顶盖承托下,模板采用木模。先支内模(吊模,用铁脚支撑模板底
In the construction of a 200m~3 reinforced concrete circular storage tank in a certain factory, the unit uses common steel scaffolding as template support to achieve good results. The tank has an inner diameter of 9m, an inner height of 3.5m, a wall thickness of 12cm, and a bottom plate and a top cover having a thickness of 10cm. Ribs φ6, 8, 10, spacing 13 ~ 26cm. Concrete No. 200 (B_8), the tank was wiped with 20mm thick 1:2 cement mortar. Due to the relatively thin wall of the pool, in order to ensure the quality of the project, a construction plan is adopted in which the pool wall and the bottom plate are once supported and the concrete is poured. The construction joints are placed under the roof support and the formwork is made of wood molds. First support internal mold (hanging mold, support the template bottom with iron feet
