Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a riser board in a wooden staircase, a unitized step board component, and an assembling method thereof.

[0002]

2. Description of the Related Art A wooden stair unit is constructed by fixing a riser plate to the front end side of a single step plate and assembling side plates at the left and right ends of the step plate to form a step of another wooden stair unit adjacent to the riser plate. The technology to assemble the board and the board
It is known from Japanese Utility Model Publication No. 4-24026.

[0003]

As described above, in the wooden staircase unit in which the riser plate and the side plate are assembled to one step plate,
In addition to the connection of the units to each other by actual fastening, the work of connecting the units to the wall panel is required each time, that is, there is room for improvement in terms of assembly work.

Further, since the wooden stair unit has a riser plate connected to the front end side of the step plate, for example, in order to improve workability, the left and right side plates on which a plurality of step plates and riser plates are assembled are assembled. On the other hand, if the nails are individually nailed from the front, the following problems occur. That is, when the step plate is nailed from the upper surface side to the side plate and the riser plate is nailed from the front side to the side plate, the rear end surface of the post-attached step plate overlaps with the lower end of the previously fixed riser plate from the front. Therefore, this portion must be nailed from the rear side and fixed to each other, and the intended workability cannot be improved.

Therefore, an object of the present invention is to fix a unit in which a riser plate is joined to a single step plate to each other only by nailing the side plate from the front and to surely fix each other. In order to improve the workability of assembling, it is possible to provide a step board component of a wooden stair.

[0006]

In order to solve the above problems, the present invention is constructed by assembling a plurality of step plates substantially horizontally between left and right side plates and assembling a plurality of riser plates substantially vertically. A step plate component in a wooden staircase, wherein the lower end of the riser plate is unitized by connecting the rear end surface of one of the step plates, and the front end surface of the step plate is opened to the lower surface, It is characterized in that a concave step portion for connecting the upper end of the riser plate is formed.

And, in the step part for wooden stairs as described above, the present invention nails the step plate to the side plate from its upper surface side, and nails the riser plate to the side plate from its front side. In addition to individually fixing the step plate component, the upper end of the riser plate is nailed to the concave step portion of the step plate from the front side of the riser plate and fixed to each other. To do.

In the above, specifically, the side plates are sasara girders, and the step plate components are sequentially assembled from the upper side.

[0009]

The step plate component of the wooden staircase according to the present invention has the lower end of the step plate in which the lower end of the riser plate is connected to the rear end face of the step plate and the upper end of the riser plate is connected to the front end face of the step plate. Since it has a concave step portion, when assembling from the front side to the side plate sequentially from the front side, the step plate is nailed from the upper surface side, while the riser plate is nailed from the front side, Is fixed individually. Then, the upper end of the rear riser plate is nailed to the concave step portion of the step plate fixed earlier from the front side thereof, so that the step plate parts are securely fixed to each other.
