<p>PURPOSE: To facilitate wiring work when a cord is bent at a junction, while increasing the wiring capacity, by cutting the corner of a floor plate obliquely at a part facing the junction of wiring trench. CONSTITUTION: The square surface plate 10 of a corner cut floor plate 1 made of a zinc plated steel plate is cut on the opposite sides at one corner thereof along a corner cut side 12 connecting the corner cut points 11 on both sides separated by a predetermined amount from the corner thus obtaining a pentagonal shape. Five sides of the pentagonal surface plate 10 are then bent perpendicularly downward to form a supporting leg 13. One or two arcuate opening 14 is made in the lower edge of the supporting leg 13, respectively, for wide or narrow side. When such corner cut floor plate 1 is employed for corner cut wiring trench, a wide wiring space can be formed and a large bend can be achieved when a hard cord is bent even if the wiring trench itself is relatively narrow.</p> |
