Claims

[Scope of Claim for Utility Model Registration] (1) In a precast concrete gutter that has engaging surfaces at both ends of a horizontal member that connects two side panels in parallel at the top or a floor board that connects at the bottom, one of the engaging surfaces is provided with a horizontal step in the center and horizontal steps with different horizontal heights on the left and right sides, a tapered hole is formed in each of the three horizontal step surfaces, and the other engaging surface is provided with the above-mentioned step. 1. A precast concrete gutter, characterized in that a step is recessed to horizontally rotate and engage with the step, and a taper hole corresponding to the taper hole is bored. (2) The precast concrete gutter according to claim 1, characterized in that the horizontally rotatable steps between the steps are such that the side steps connecting the center step and the left and right steps form a tapered surface toward the center. (3) The plate according to claim 1 or 2, characterized in that the horizontal rotation between the steps is such that the centers of the tapered holes bored in the center step and the left and right steps are shifted in a direction perpendicular to the engagement surface. Cast concrete gutters.
