<p>PROBLEM TO BE SOLVED: To simply and certainly carry out construction work at a working site and to regulate positions, intervals, etc., by providing a projection extending in the width direction and an engagement protrusion to constitute a groove in which the projection can fit free to slide at relative positions on a lower surface of a base. SOLUTION: A pillow base has a semi circular arc pipe receiving part 11 on an upper surface of a rectangular base, and a dent and a protrusion 12b to be fitted on each other are provided on relative positions on both sides of the upper surface. Additionally, a recessed part 13a and a projecting part 13b to be fitted on each other are provided on both side surfaces of the base, and it is devised so that the recessed part 13a and the projecting part 13b of the adjacent left and right pillow bases are fitting on each other connected to each other. In the meantime, a projection 14b extending in the which direction and an engagement protrusion 14a to constitute a groove in which the projection 14b can fit free to slide are provided on relative positions on a lower surface of the base. Consequently, it is possible to regulate positions, intervals, etc., of conduit pipes, etc., supported on the pillow base by sliding a pair of the upper and lower pillow bases in the width direction.</p> |
