混凝土施工中的模板,主要是起到定型和支撑的作用,同时兼具保温效果。但何时可以拆模,必须得具体部位具体分析。对于承重的模板(如底模),过早拆模时结构物强度较低,容易引发结构变形甚至垮塌,但是拆模时间过晚又会影响模板及支撑的周转效率。目前,对于承重的模板何时可以拆模,在相关的施工规范GB 50666-2011《混凝土结构工程施工规范》中有明确规定,主要参看的是实体强度,不同跨度以50%、75%或100%
Concrete construction template, the main role is to play a role in stereotypes and support, while both insulation effect. But when you can disassemble, you must have specific parts of the specific analysis. For the load-bearing template (such as the bottom mold), premature demolition of the structure lower strength, easily lead to structural deformation or collapse, but the demolition of the mold too late will affect the template and support turnover efficiency. At present, when the load-bearing template can be removed from the mold, the relevant construction code GB 50666-2011 “Concrete Structure Engineering Construction Code,” clearly defined, the main reference is the physical strength of different span of 50%, 75% or 100 %
