摘要
常规施工中,钢管脚手架的搭设是随着建筑物的升高而升高的,并依据建筑物外轮廓和施工要求,事先确定内立杆到建筑物的距离,安全度高。而在已完工程的局部改造中,脚手架应按改造后的建筑物外轮廓进行搭设,而附墙须在原有建筑结构上进行。当建筑物外轮廓变化时,或当脚手架附着点的结构拆除后,会造成纵横向附墙距离或附墙杆成倍加大的问题。对此,探讨在局部结构改造中,为保证脚手架安全使用,脚手架的搭设、附墙的设置方法等。
During routine construction, the height of steel tubular scaffold increases when building height increases and the distance from the internal tube to the building and safety height are determined in advance according to the building profile and construction requirements. During local rebuilding of finished project, the scaffold shall be erected according to the profile of rebuilt building, and attaching wall must be constructed on the original building structure. When building profile changes or when the structure on which the scaffold is attached to, the distance of longitudinal and transverse attaching walls or attaching wall tube may be doubled. Therefore, the setting method of scaffold erection and attaching wall are discussed in local structural rebuilding, so as to guarantee the safe application of scaffold.
