在建筑加固改造中,对补楼板洞,大量运用的是压型钢板上浇筑混凝土的施工工艺,一般称为压型钢板与混凝土组合楼板,简称为组合楼板。这种楼板用压型钢板代替了模板,施工简单,迅速,缩短了施工周期,因而在加固改造中得以广泛运用。压型钢板分为开口板和闭口板两种(图1)。 In the building reinforcement and transformation, to fill the floor hole, a large number of the use of the pressure on the steel pouring concrete construction technology, commonly known as the pressure plate and concrete composite floor, referred to as the composite floor. This floor instead of the use of steel plate template, the construction is simple and rapid, shortening the construction cycle, which in the reinforcement of the transformation has been widely used. Profiled plate is divided into two kinds of open plate and closed plate (Figure 1).
