PURPOSE: A grated block of a thermal treatment facility is provided to reduce the number of grated blocks by arranging pipes to be symmetrical to the plane symmetrical lengthwise of a grated block. CONSTITUTION: A grated block(1) is composed of: an upper wall(23) while forming a left side wall(29a), a right side wall(29b), a front wall(24) and a rear wall(21); a hook(22) formed on the rear wall; a symmetric face(S) extended in the same direction as lengthwise direction and formed to be orthogonal to the horizontal face; a pipe(16) connected to a water supply connection part(30) to be symmetrical with each other against the symmetric face; a carved part(16a) of the pipe extended lengthwise to the first front wall; a curved carved part(16b) connected to the carved part; and another lengthwise carved parts(16c,16d,16e) connected sequentially. Herein, the pipe(16) is placed to separates from the rear wall to easily approach to the water supply pipes(30,43).
