【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 show a fixing structure of a step plate and a riser plate in a staircase. As shown in these drawings, in the fixing structure 1 of the step plate and the riser plate of the present embodiment, the recess 20B is continuous with the groove 30A formed in the step plate 30 of the conventional stairs 3. Is only different. Therefore, the same members as those of the related art will be designated by the same reference numerals, and the description thereof will be omitted or simplified.

The staircase 2 of this embodiment is configured to include a plurality of step plates 20, a plurality of riser plates 31, and a plurality of side plates (not shown). Structure 1 is a structure in which a riser plate 31 is fitted on the lower surface of such a step plate 20 and nails 32 are further driven to fix them.

That is, a groove portion 20A is formed on the back surface of the step plate 20 along the longitudinal direction of the step plate 20 and extends to the vicinity of both ends in the longitudinal direction. The groove portion 20A has an upper end of the riser plate 31. The part 31A is adapted to be fitted. Further, a recess 20B continuous with the groove 20A is formed at the rear of the groove 20A (on the right side in FIGS. 1 and 2), and the recess 20B is formed at both ends of the groove 20A as shown in FIG. It is provided in two places. As shown in FIG. 1, the concave portion 20B is formed with an inclined surface 20C which spreads downward from the top thereof.

The lower end portion 31 B of the riser plate 31 contacts the front face of the riser plate 31 with the rear end face of the step plate 20, and then drives the nail 33 from the rear face of the riser plate 31 to fix them. There is.

In order to fix the step plate 20 and the riser plate 31 as described above, the upper end portion 31A of the riser plate 31 is inserted into the groove portion 20A of the step plate 20, and the upper end surface thereof is brought into close contact with the groove surface of the groove portion 20A. This is confirmed by looking at the recess 20B, and then the nail 32 is driven from the recess 20B so as to reach the step plate 20 by diagonally penetrating the fitting plate 31. The lower end portion 31B of the striking plate 31 makes the front surface of the riser plate 31 contact the rear end surface of the step plate 20, and then drives the nail 33 from the rear surface of the riser plate 31 toward the step plate 20 to remove both. Fix it.

According to this embodiment as described above, there are the following effects. That is, since the recess 20B formed on the lower surface of the step plate 20 is formed to have the same depth as the groove 20A, when the upper end 31A of the riser plate 31 is inserted into the groove 20A, they are in close contact with each other. Can be confirmed. Therefore, if the nail 32 is driven in that state, the riser plate 31 will not slide in the groove 20A, and no squeak noise will be generated when a person rides on the step plate 20.

Further, although the nail 32 is driven obliquely, the step plate 20 has a recess 20B formed therein, and the recess 20B has an inclined surface 20C. The bottom surface of the plate 20 is not obstructed, and the nail 32 can be firmly hit, thus improving workability.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but includes the following modifications. That is, although the recesses 20B are provided at two locations on both ends of the groove 20A in the above-described embodiment, the number of the recesses 20B is not limited, and may be more than three, for example, three locations evenly arranged, or the trenches. It may be continuous along 20A. The point is that it can be confirmed that the upper end 31A of the riser plate 31 is in close contact with the groove 20A, and that the nail 32 can be easily driven.

Further, the recessed portion 20B in the above-mentioned embodiment is left as a space after the nail 32 is driven from there, but the adhesive is not applied after the nail 32 is driven into the recessed portion 20B. It may be embedded. By doing so, the strength of the recess 20B after the adhesive is hardened is increased, and as a result, the riser plate 31 is more firmly fixed. In particular, when the recess 20B is continuous along the groove 20A, the strength of the recess 20B can be increased by the adhesive.

In addition, the specific structure, shape, and the like when implementing the present invention may be other structures and the like as long as the object of the present invention can be achieved.
