を簡便に行うことができる。 On the other hand, both ends of the second upper member in the width direction are made of plastic or metal, and a rubber member is sandwiched between them, and this rubber member has a space inside to prevent the concrete from expanding and contracting. It can be definitely absorbed. Further, if the height is higher than that of the first upper member, after removing the first upper member, a finishing layer of a predetermined thickness can be easily applied from the first concrete pouring surface.
更に第２上部部材は、その上表面は目地材の幅

部材と交換できる。 In addition, since the center part of the second upper member is made of rubber, it has excellent wear resistance, but if the second upper member is damaged, the second upper member is removably engaged with the upper part of the leg. Therefore, it can be easily replaced with a new second upper member.
