在施工现场,我们经常会看到现浇钢筋混凝土梁板在拆除全部模板之后,仍然在某些部位加设立柱,试图继续支承这些梁板构件。但这些“想当然”的安全措施,在某些场合下,不但起不到安全作用,反而更容易出现质量问题。现浇钢筋混凝土构件在拆除模板系统之后,就开始按其结构形式承受自重及上部荷载。而构件的支座位置及数目直接决定着构件中产生的内力。是单跨还是多跨,是悬臂

At the construction site, we often see in-situ reinforced concrete slabs still adding pillars in certain locations after attempting to dismantle all the stencils in an attempt to continue supporting them. However, these “foreign” security measures, in some cases, not only do not have a security effect, but are more likely to have quality problems. After the cast-in-place reinforced concrete components are removed from the formwork system, they begin to bear their own weight and upper load according to their structural form. The position and number of the bearings of the components directly determine the internal forces generated in the components. Is it a single span or multiple spans that are cantilevered
