混凝土施工中所用的定型组合钢模板是把定型板块和纵横楞条用连接件预先组合成大型模板,具有一定的刚度,可用吊装机械进行整体装拆转运,一次拚装多次周转使用,使模板工程也能进行机械化施工。当然,这种模板也可由人工就地装拆运搬,但其技术经济效果是有所不同的。这种钢模板是六十年代的产物,我国目前使用的钢模板大致采用了日本的工业标准,而日本则是从欧洲引进的。工业发达的 The combined steel template used in concrete construction is pre-assembled into a large template with connecting pieces of the forming plate and vertical and horizontal purlins, with a certain degree of rigidity, and can be assembled, disassembled, and transported by a lifting machine, and assembled and used several times at once to make the template. The project can also be mechanized. Of course, this kind of formwork can also be loaded, unloaded and transported manually on the spot, but its technical and economical effects are different. This kind of steel formwork was the product of the 1960s. The steel formwork currently used in our country is roughly the same as the Japanese industrial standard, while Japan is imported from Europe. Industrially developed
