<p>According to an embodiment of the present invention, a deck panel includes: a steel plate; a TPO sheet which is installed to be in parallel with the steel plate while being spaced apart from the steel plate by a predetermined distance; and a foamed body which fills the space between the steel plate and the TPO sheet. The TPO sheet includes an extension unit which is extended to the outside further than an end of the foamed body. According to the present invention, the deck panels, which include a thermoplastic polyolefin sheet, can be attached without a gap between without using an additional member. The horizontality rate of the TPO sheet can be maintained in a certain level or greater even when a large amount of an insulation or filler material is injected between the steel sheet and the TPO sheet.</p> |
