A slat for use in a roll-out sheet of construction material is provided. The slat has an elongated body extending longitudinally. A projection is disposed at a first lateral end of the body. A socket is disposed at a second lateral end of the body, opposite to the first lateral end. The projection and the socket are structurally complementary to each other. A wedge is formed with the projection as a self-tightening mechanism. A roll-out structure is also provided. The roll-out structure has at least two adjacent slats which are structurally the same. The projection of one of the slats is insertable into the socket of the other slat to connect them, and the projection is rotatable in the socket. The rotation of the projection in the socket allows the wedge to engage the socket, to lock the slats with each other. |
