In recent years, most of the building structures are composite low-load concrete structures using a combination of concrete, which is a compressive material, and low-current, which is a tension material. When the curing is completed by injecting concrete is made through the demolition work to remove the formwork, there was a problem that the air is long.

As a result, most of the current concrete slab structures currently constructed are constructed by laying deck panels for formwork between beams and beams, and by disposing concrete on top of them so that the construction and dismantling of formwork is unnecessary. The construction and finishing work of the structure is to be done quickly at the same time.

However, the above-mentioned conventional formwork deck panel is not only necessary to install and dismantle the formwork, but additional reinforcement is required for strong settlement between the surface of the deck panel and the concrete, and additional labor is required as well.
