。DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the contents of the present invention will be explained in detail with reference to the drawings. FIG. 2 is a plan view of the plywood for concrete formwork of the present invention,
FIG. 3 is a front view of the same. On one or both sides of the formwork plywood 3, ruled lines 8 are drawn parallel to the vertical and horizontal edges of the formwork plywood 3 at regular intervals and orthogonal to each other in a checkerboard pattern. The interval d between the ruled lines 8 is not particularly limited, but for example, in the case of plywood for concrete formwork of 900 mm x 1800 mm, which is the most commonly used standard size, an interval of 50 mm or 100 mm is preferably used. It is necessary to draw the ruled line 8 so that the position of the ruled line 8 relative to the edge of the formwork plywood 3 is at an accurate and constant position. The intervals between the ruled lines 8 in the vertical and horizontal directions may be the same or different.

。When drilling the through holes 5 at the construction site, in order to make it easier to select an appropriate drilling position from the intersection of the ruled lines 8, etc., holes are usually drilled in the formwork plywood 3 during formwork assembly. It is desirable to mark the perforation mark 9 in advance at the standard perforation position to be used. The position of the drilling mark 9 is, for example, 900 mm x 18
In the case of 00mm standard concrete formwork plywood, holes are drilled in 6 locations, but as shown in Figure 2, the 6 most commonly used locations are A, and the next location a certain distance away on both sides from each location. If you mark the drilling marks 9 at a total of 18 of the 12 drilling positions B that are often used in
By selecting and drilling six of the eight drilling marks 9, it is possible to handle most drilling operations.

may be provided on only one side of the formwork plywood 3, or may be provided on both sides. When providing the ruled lines 8 only on one side, it is desirable to provide the ruled lines 8 on the surface side of the formwork plywood 3 that is in direct contact with the concrete to be poured. In order to cut or perforate the formwork plywood 3 before assembling the formwork, it is sufficient to draw a ruled line 8 on only one side of the formwork plywood 3, but it is sufficient to draw the ruled line 8 on only one side of the formwork plywood 3. It may be necessary to drill holes, and in that case it is convenient to draw ruled lines 8 on both sides of the formwork plywood 3. Furthermore, the ruled lines 8 may be provided on the entire surface of the formwork plywood 3, or may be provided only on necessary portions. Furthermore, it is also possible to provide only the perforation marks 9 without providing the ruled lines 8.

Furthermore, the plywood for concrete formwork of the present invention is not only a normal planar plywood in which the grains of veneers are laminated alternately in the vertical and horizontal directions, but also a curved cylindrical plywood in which most of the grains of the laminated veneers are laminated parallel to each other. The same applies to possible so-called parallel plywood (bent plywood). Furthermore, it is also used for curved plywood that is formed into a cylindrical surface with a constant curvature during the manufacture of plywood. These parallel plywood and curved plywood are used for formwork for parts where concrete is poured in a curved shape.
