Among these, the plurality of Tyco materials or the lumber 11 having a square shape in the base layer 1 have the same thickness and are arranged so as to be adjacent to each other in the width direction. Each lumber 11 is a structural lumber made of coniferous wood, and a Tyco lumber is shown in FIG. 1. However, the timber 11 is not limited to this. It may be lumber. The dimensions of each lumber 11 are not particularly limited, but for example, the length in the longitudinal direction is 4000 mm, the length in the width direction is 200 to 300 mm, and the thickness is 90 mm. The length of each lumber 11 in the width direction may be longer than the thickness. The length in the longitudinal direction of each lumber 11 is not particularly limited as long as it can be bridged from beam to beam, but may be, for example, 2000 mm or more, or 2500 mm or more. , 3000 mm or more, 3500 mm or more, or 4000 mm or more. In addition, in this specification, "horns" means that the short side of the wood mouth is 75 mm or more. Revision: According to the classification of timber according to June 12, 2013 Ministry of Agriculture, Forestry and Fisheries Notification No. 1920).

As a comparative example, when a lumber having a small size is used, it cannot support the span from beam to beam by itself, and therefore it is necessary to support many supporting works to hold the formwork panel. In this case, the supporting work cannot be removed until the strength of the concrete is developed, and other work cannot be performed while the supporting work is standing. On the other hand, in the present embodiment, referring to FIG. 4B, by using the Tyco material or the horned lumber 11 in the base layer 1, it is not necessary to hold the concrete 33 by supporting work until the strength of the concrete 33 is developed.

Boards such as plywood are used as the first wood board 12. The dimensions of the first wood board 12 are not particularly limited, but for example, the length in the longitudinal direction is 4000 mm, the length in the width direction is 1000 mm, and the thickness is 12 mm. The first wood board 12 and the lumber 11 or lumber 11 are fixed, for example, with nails.

The second wood board 13 in the second outer skin layer 3 is arranged so as to cover the second surface 1b (the lower surface in the illustrated example) of the base layer 1 opposite to the first surface 1a. Is fixed to each of the plurality of tyco lumber or horned lumber 11 in FIG. Boards such as plywood are used as the second wood board 13. The dimensions of the second wood board 13 are not particularly limited, but for example, the length in the longitudinal direction is 4000 mm, the length in the width direction is 1000 mm, and the thickness is 12 mm. The second wood board 13 and the lumber 11 or lumber 11 are fixed with nails, for example. Of the plurality of tyco lumber or horned lumber 11, some lumber 11 is fixed only to the first wood board 12, and the remaining tyco or horned lumber 11 is fixed to the second wood board 13. It may have been done.

The second wood board 13 may have flame retardancy or noncombustibility. As shown in FIG. 4B, in the steel building 30, when the second outer skin layer 3 is arranged so as to be exposed to the ceiling, the second wood board 13 is subjected to a flame-retardant or non-combustible treatment. Thereby, it becomes possible to make the lumber form panel 10 conform to the standard regarding flame resistance.
