Technical Field
The invention relates to the field of fabricated buildings, in particular to a composite floor slab.
Background
With the development of modern industrial technology, building houses can be manufactured in batches like machine production. The prefabricated house components are transported to the construction site and assembled. The assembly type building is fast in construction speed and low in production cost, and therefore the assembly type building is rapidly popularized and developed.
In the production of prefabricated components of the fabricated floor, because the end of a common composite floor slab is provided with an extended steel bar, a through hole for the extended steel bar to penetrate through needs to be formed in the corresponding position of the flange of the forming die. However, the positions of the extending steel bars of the composite floor slabs with different sizes are different, and the flanges of a specific mold need to be manufactured, so that the production efficiency, the processing cost and the turnover cost of the mold are influenced, and the production cost of the composite floor slabs is increased.
