上記架台３上に精度よく位置決めしたとしても例
えばコンクリート打設時においてこのものが変形
したり一方に倒れ込んで位置が狂う場合もある。 In the case of items that need to be installed or fixed on the floor, such as the pillars of large machines, heavy objects, or other structures, the floor surface must be made sufficiently robust to withstand the load of these heavy objects, and the It is necessary to provide protruding anchor bolts to secure objects. As shown in Fig. 1, the structure of the floor surface for this purpose has conventionally been such that a box frame-like structure made of a steel frame assembly is placed inside the reinforced concrete frame 1 constituting the floor, facing the installation surface of the base 2 of the structure. The anchor bolt mount 3 is buried, and the base is joined with anchor bolts 4, 4 on the internal frame 3a of the anchor bolt mount 3, facing the bolt holes formed in the base 2. At the periphery of the projecting end from above the floor surface, a raised concrete portion having at least the same outer periphery as the outer periphery of the base 2, that is, a foundation installation portion 5 is formed in a state one step higher than the floor surface. However, when forming a floor surface on such a structure, all conventional construction methods have been carried out on-site.
That is, in order to make the foundation installation part 5, reinforcement is arranged at the anchor bolt installation position, a formwork is made,
After pouring concrete into the frame and leveling the surface, the formwork materials must be dismantled and transported, and finally the surface must be finished by painting. Since each of these work processes is performed by a different job type, the human and time management of the process is complicated, and when there are many foundation parts to be installed, it is difficult to determine the position of each anchor bolt. Although the installation is carried out at each set position, this requires an extremely large amount of time for installation, and there is a great possibility that dimensional errors will occur if the parts are installed individually. In particular, it is extremely difficult to accurately position and fix the anchor bolt 4, and even if it is accurately positioned on the pedestal 3, the anchor bolt 4 may deform or fall to one side during concrete pouring, causing the position to go out of order. There is also.
