PROBLEM TO BE SOLVED: To provide a receiving container enabling the horizontality of a foundation to be kept.SOLUTION: A receiving container 10 comprises a bottom surface part 11, two side surface parts 12, a front end face 13, and a rear end face 14. The bottom surface part 11 is rectangular, and has a foundation bottom surface 111 corresponding to the width of the foundation and an extended face 112 which is rearward longer than the width of the foundation. The two side surface parts 12 are raised by being inclined from both side edges of the bottom surface part 11 to an in-rectangle direction and abut with the underside of a bed. The front end face 13 is raised from the front end of the bottom surface part 11 at one end side of the side surface parts 12. The rear end face 14 is raised from the rear end of the bottom surface part 11 at the other end side of the side surface parts 12. After the bottom surface part 11 is inserted between the foundation and the bed, mortar in a fluid state can be poured into the receiving container from above the extended face 112 of the bottom surface part 11. The mortar is filled up to the underside of the bed inside the receiving container 10, and when the mortar is cured, the mortar and the receiving container 10 support the bed. |
