自从《小砌块模板代替木模板》一文在《中国建材》1985年第1期刊出后,陆续收到安徽、河南等地一些同志的询问信,现综合答复如下: 一、产生砌块模板所用的混凝土标号应≥200号。各种掺合料如砂、石,必须先用水洗净,配比准确,搅拌均匀,碎石或砾石的最大粒径不得超过10毫米。为适应组砌安装、接茬及施工的最不利荷载的需要,在砌块模板内配置一定数量的构造钢筋,以满足所需要的强度、刚度、稳定性。 Since the “Small Block Template Replaces a Wooden Formwork” article published in the first periodical of “China Building Materials” in 1985, successively received letters from some comrades in Anhui, Henan and other places. The comprehensive reply is as follows: 1. The block template used The concrete marking should be ≥200 numbers. All kinds of admixtures, such as sand and stone, must be washed with water first, and the mixing ratio should be accurate, and the mixing should be uniform. The maximum size of gravel or gravel should not exceed 10 mm. In order to meet the needs of the most unfavorable loads of the installation, jointing and construction of the group, a certain number of structural reinforcements are arranged in the block template to meet the required strength, rigidity and stability.
