PROBLEM TO BE SOLVED: To make it possible to easily install jointing pieces on a flat floor in a short time in any case, to reduce a construction process such as in a foundation work on a floor surface at the time of installation of equipment such as an automatic vending machine and also to significantly reduce both construction expenses and construction time. SOLUTION: As shown in a figure, a groove 1 is formed by bending and working a rectangular metallic plate so that its section looks like a C shape, wherein an interception stick 4 of a groove for connecting both sides 2 and 3 is provided near one end of the groove, and holes 6 and 7 ion which a fix stick 5 can be inserted are provided in a symmetrical position with both walls 2 and 3 near the other end of the groove. Furthermore, jointing pieces for equipment legs and the surface floor have reinforcing metallic plates 8 and 9 welded in a surface in contact with a floor at both end parts of the groove and have double face adhesive mats 10 and 11 on its rear side. |
