Description of the Related Art In general, a building foundation is constructed by placing a concrete base on the upper layer of crushed stone laid in a root cut of the ground, setting up a vertical portion of a reinforcing bar above the concrete base, and sandwiching the vertical portion. Usually, a pair of molds are raised and held in parallel with each other, and concrete is filled in the space between the molds and air-dried. As means for holding the rebar and formwork,
It is also practiced to embed the lower end of the reinforcing bar in the concrete base and place the formwork on the upper surface of the concrete base, but in this case, finish the upper surface of the concrete base flat before placing the formwork, Further, since it must be dried and cured, it takes time and effort, and the construction period is prolonged. Therefore, with the aim of saving time and labor by simultaneously placing the concrete base and the concrete in the formwork, a base is placed on the crushed stone, and a reinforcing bar and multiple formwork are placed on the upper side of the base. A support base is provided, and a pair of formwork is raised and held above a support base with a reinforcing bar therebetween. In this building foundation, in order to arrange the formwork at a predetermined position, it is necessary to position each support base and align them with each other.

従来、その型枠用支持台の位置決めは水準器や寸法測

い。Problems to be Solved by the Invention However, when positioning is performed using a level and a dimension measuring device, the height and the lateral position must be measured while maintaining the level of the support table, and further, the deviation from the reference position must be adjusted. I have to save time and effort. In addition, when positioning the reference portion of the support base with the yarn stretched at the reference position and positioning, it is necessary to stretch a plurality of yarns in order to align all the horizontal, height, and lateral positions. In addition, these yarns not only hinder the positioning operation, but it is inevitable that it is difficult and troublesome to stretch all the yarns at the reference position.
