近年来,人们将压型薄钢板作为混凝土楼板的永久模板,与混凝土组合,共同承担工作荷载,这就是混凝土-钢板组合楼板。在建筑工程中使用混凝土-钢板组合楼板可简化施工工序,加快施工速度。一般组合楼板梁板体系按无支承方式设计,当混凝土达到一定的强度后,组合板的压型钢板模板通过一定形式的内锁、锚固及与混凝土的粘结,与混凝土板组合,共同工作,成为楼板的加强筋。常见压型板形状有两种,一种是燕尾形压型板,另一种是翼缘带凸凹槽的梯形压型板。压型板的折起高度一般在38～75mm之间,所用钢板厚度为0.18～1.5mm。这类
In recent years, people have used pressed sheet steel as a permanent form for concrete floors, combined with concrete and working load together. This is the concrete-steel composite floor slab. The use of concrete-steel composite floor slabs in construction projects can simplify the construction process and speed up construction. The general composite slab slab system is designed in an unsupported manner. When the concrete reaches a certain strength, the profiled steel plate formwork of the composite plate is combined with the concrete slab through a certain form of internal locking, anchoring and bonding with the concrete, and works together. Become a floor rib. There are two common pressure plate shapes, one is a dovetail profile plate, and the other is a trapezoidal profile plate with a flange with a convex groove. The folded height of the press plate is generally between 38 and 75 mm, and the thickness of the steel plate used is 0.18-1.5 mm. This type
