The floor slabs used in prefabricated buildings are largely factory-produced interlocking prefabricated ribbed slabs, on which a layer of concrete is poured. After the concrete reaches the design strength, a laminated slab with two-way reinforcement can be formed. The production of such slabs enabled the industrialization of construction.
现有的预制带肋底板叠合板存在如下的问题与缺陷：一、底板生产的工业化程度低，制作肋和肋上的孔洞时耗费人工多，花费时间长，成本高，二、肋上孔洞较少、较小，一般情况下，管线不能交叉，只能横平竖直穿过，不但耗费管线，而且有直角，不便于电线穿越。Existing prefabricated ribbed floor laminates have the following problems and defects: 1.

The holes on the ribs are relatively small Fewer and smaller. Under normal circumstances, pipelines cannot cross, but can only pass horizontally and vertically. This not only consumes pipelines, but also has right angles, which is not convenient for wires to pass through.
