The connection groove is formed between the upper and lower sides. Each connection joint has a connection wing, a lower space retainer, and an upper space retainer. The connection wing is coupled to the connection groove of the deck and has a screw coupling hole. The lower space retainer is protruded from the bottom center of the connection wing.
