These nails 11 are driven one by one at one end side in the longitudinal direction, in this case, at the right end of the base body 2 for each one piece of the base ring. In other words, one of the connecting portions 3 of the pedestal wheels 1 with ventilation holes connected via the respective connecting portions 3 and 3 is connected to the nail 1
By fixing at 1, the connecting portions 3 and 3 are in a state where they are restrained from moving in the width direction, and the adjacent wheels 1 and 1 with ventilation holes are restrained from moving in the width direction.
When only one connecting portion 3 is fixed, the wheel 1 including the one connecting portion 3 is fixed, and the wheel 1 including the other connecting portion 3 is also fixed. Therefore, unlike the related art, it is not necessary to fix the wheel 1 at both ends for each piece of the wheel, and only one end needs to be fixed. Is being planned.

Is applied to the upper surface of the base 7, the base 1 can be easily and accurately set by matching the marking M portion of the base 1 with ventilation holes to the base. further,
The through-hole 6 for allowing the anchor bolt to pass through the undercarriage body 2 so as to penetrate the undercarriage body 2 in the vertical direction while keeping a predetermined interval along the longitudinal direction of the undercarriage body,
Since the base ring 1 is installed on the foundation of the portion where the anchor bolt 10 protrudes, the through hole 6 at an appropriate position is selected from the plurality of through holes 6 and the anchor bolt 10 is formed. Is inserted, the installation position of the undercarriage 1 can be adjusted. Also, after the trolley 1 is set on the foundation, the marking M of the trolley 1 becomes a position marking when a structure body such as a floor panel (see FIG. 4) to be set on the trolley 1 is set. Thus, the floor panel constituting the structure main body can be accurately installed.

Therefore, a large amount of wind from the width direction of the undercarriage body 2 can be taken in, and the ventilation volume of the ventilation hole 4 can be increased. Therefore, the underfloor ventilation holes generally provided in the foundation portion can be omitted, the labor of the foundation work can be simplified, and the ventilation volume of the space sandwiching the foundation 7 is increased, and The ventilation efficiency can be increased by increasing the ventilation efficiency inside and outside the foundation 7 on which the main body is provided.

Thus, the nail 11 can be inserted through the nail hole 5 and securely fixed to the foundation 7 in a state where the head of the nail 11 is housed in the dugout 51. In addition, even when the base body 2 is installed upside down on the foundation 7, the nail 11 can be inserted into the nail hole 5 and the head of the nail 11 can be stored in the dugout 51. Furthermore, since the ventilation hole 4 and the nail hole 5 do not communicate with each other in the main body 2, the ventilation efficiency is not reduced by the nail hole 5. In addition, since the effective ventilation area of the opening 41 of the ventilation hole 4 is 300 cm 2 or more per 4 m of the length of the pedestal main body, the ventilation hole 4 can secure a necessary and sufficient ventilation volume.
