赵恒树(山东亿辰混凝土有限公司,高级工程师)结构混凝土构件分为两部分,其一是竖向构件,其二是水平构件。竖向构件(包括水平构件的侧模)在拆模时只要考虑混凝土具有一定的强度(1.2MPa以上),在拆模时不掉角,不去楞为原则。可是有些施工单位为了赶工期,在混凝土终凝后即行拆模,造成构件出现缺角掉棱现象。更有甚者,有的木工师傅凭着以往的施工经验,到时候就拆模,结果造成了部分墙柱坍塌,也有的墙柱在箍筋下出现水平裂 Zhao Hengshu (Shandong billion Chen Concrete Co., Ltd., Senior Engineer) Structural concrete components are divided into two parts, one is the vertical component, the second is the horizontal component. Vertical members (including horizontal members of the side mold) in the demolition of mold as long as the concrete has to consider a certain strength (1.2MPa above), the demolition of the mold is not lost, not to Leng principle. However, some construction units in order to catch the construction period, the final setting of concrete after the line disassembly, resulting in the phenomenon of missing pieces off edge phenomenon. What is more, some carpenters with past construction experience, the demolition of the mold at the time, resulting in the collapse of some columns, and some columns appear horizontal stirrup
