The peaks and valleys 31 and 32 may be arranged so as to extend in the longitudinal direction parallel to the joist 2 in consideration of the arrangement space and the like.

As the corrugated plate 3, a keystone plate can be preferably used. The keystone plate is a galvanized steel sheet whose cross section is corrugated with repeated peaks and valleys in order to increase the strength against load. The keystone plate has been conventionally used for a concrete frame, a floor plate, or the like, but in the present embodiment, it is adopted as a base structure 1 of a deck, and an artificial turf mat 7 is adopted as a member to which it can be attached. Since the keystone plate is composed of continuous peaks and valleys 31, 32, it is possible to increase the strength of the base structure 1 in spite of its light weight.

In FIG. 1, as the shape of the corrugated plate 3, the number of mountain portions 31 is seven, the number of valley portions 32 is six, and the edge portions 33 of the mountain portions 31 at both ends are two when viewed from the top and bottom directions shown in the drawing.

It may be 50 mm. As for other dimensions, those having a working width of 650 mm and a thickness of 0.8 mm from one edge 33 to the other 33 can be used, but in any case, the dimensions of the corrugated plate 3 are , Not limited to these. From the viewpoint of the strength required for the base structure 1, those having different dimensions may be used.

<Bar material 4>
Returning to FIG. 1, the bar material 4 is fitted into at least a part of the valley portion 32 of the corrugated plate 3. Here, an example is shown in which all of the bar members 4 are fitted into the valley portion 32 from the left end portion of the corrugated plate 3 to the right direction by about seven minutes. The section in which the bar member 4 is fitted into the valley portion 32 is generally the entire section of the valley portion 32, but it may be appropriately adjusted according to the shape of the contour of the deck and the like.

The cross section of the bar material 4 is shown in FIG. 2 together with the cross section of the corrugated plate 3. As shown in FIG. 2, the corrugated plate 3 is composed of a gently diverging mountain portion 31 and a correspondingly gentle buttock valley portion 32, and the bar material 4 is a buttock. It is fitted into the valley portion 32 in an inverted trapezoidal shape in a side view so as to correspond to the valley portion 32 of the dent. An artificial turf mat 7 or the like can be placed on the top surface 41 of the bar material 4.

The bar material 4 has a substantially C-shaped cross section in which the lower part is open, and more specifically, the top surface 41 and the left and right side portions 42a, which hang down from both sides of the top surface 41 inward. It is composed of 42b and left and right extending portions 43a and 43b extending inward in the horizontal direction from the left and right side portions 42a and 42b.
