Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a structure of stairs constructed in an industrial production house, for example.

<Prior art> Wooden stairs in houses are assembled by alternately mounting step plates and riser plates on the sasara girders on the left and right sides. As this step plate, a plate in which a sheet-shaped decorative plate is adhered is often used near the upper side of the substrate, the front end face and the lower face near the front side edge. Furthermore, real public Sho 59-1
As described in Japanese Patent No. 6432, there is one in which a decorative plate of a substrate is continuously hung and formed into a kick.

<Problems to be Solved by the Invention> In the above-mentioned conventional stairs, when the step plate and the riser plate are assembled, the step plate and the riser plate are made of separate members, so that the assembling work becomes complicated. In particular, it is not easy to attach the kicking plate to a predetermined position because the decorative plate that constitutes the step plate is used as it is, and the kicking plate itself is the decorative plate itself, so there is a problem in durability at the above-mentioned mounting position.

The present invention is to provide a stair structure having high practical value such as ease of assembly.

<Means for Solving the Problems> That is, in order to achieve the above object, the staircase structure according to the present invention comprises a sasara girder, a plurality of step plates mounted substantially horizontally to the sasara girder at predetermined intervals, and In a staircase including a riser plate provided substantially vertically on the back side between the step plates, the step plate covers the upper surface, the front end surface, and the lower surface front side of the step board substrate fixed to the sassar girder with a decorative plate. With it, the decorative plate on the lower surface is bent outward at a substantially right angle to hang it down to the lower step plate,
This is formed as a riser plate, and a reinforcing plug is embedded in a space formed by the upper end of the riser plate and the lower surface of the step board, and the lower end is a decorative board that covers the upper surface of the sasara girder and the step board. It is characterized by being held in.

<Operation> In the present invention, each face of the stepped plate substrate is continuously covered with each face portion of the decorative plate made of a continuous body to complete the stepped plate. At the same time, the riser plate is also provided at a predetermined position.

Further, since the reinforcing plug is embedded between the upper end of the riser plate and the lower face of the step plate, and the lower end is sandwiched between the sasara girder and the decorative plate of the lower stage plate, the durability of the insert position of the riser plate is improved.

<Embodiment> An embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the staircase 5 of the present embodiment comprises a step plate 3 placed on the sasara girder 2 and a stair member 1 which covers the step plate 3 and also serves as a riser plate 4. The step plate 3 comprises a step plate substrate 6 and a decorative plate 7 covering the step plate substrate 6, and the step member 1
Is formed as a continuous plate-shaped member that constitutes the decorative plate 7 and the riser plate 4. The width thereof is the length of the step substrate 6, that is, the opening width of the stairs 5 is matched with the length of the step substrate 6, that is, the opening width of the steps 5. The decorative plate 7 covers an upper surface 9 in a range in which the back side edge 8 of the step board 6 is removed by the thickness of the riser plate 4, a front end face 10, and a lower surface 11 in a range from the front end face 10 to the riser plate 4. It is a plate material set for use.

The staircase member 1 uses a laminated plate as the decorative sheet material 12, and is in the form of a multi-layered member which is attached to the surface of the substrate 13. As shown in FIG. 2, the substrate 13 portion of the staircase member 1 is divided into 45 degrees from the vertical plane with respect to the substrate 13 with the thickness of the decorative sheet material 12 remaining, and the inner bent groove-shaped cross section 14, The so-called V-cut groove and the outwardly bent groove-shaped cross section 15, so-called slit, are cut. The points to be cut into the inwardly bent groove-shaped cross section 14 are the upper surface 9, the front end surface 10 and the lower surface 11 of the step board substrate 6.
16a, 16 which corresponds to the intersection of each surface with
b. The portion cut into the outwardly bent groove-shaped cross section 15 is a portion 17 corresponding to the tangent line between the range of the decorative plate 7 and the riser plate 4.

The area of the decorative plate 7 of the continuous plate-shaped stair member 1 cut and processed as described above is sequentially attached and covered on each of the surfaces of the step board 6 with an adhesive. With this, the step plate 3 is completed. When the step plate 3 is made horizontal, the riser plate 4 is vertically lowered on the lower surface 11. When the step plate 3 is placed on the sasara girder 2 in that posture, the lower step as shown in FIG. In the step plate 3 on the side, since the upper surface 9 on the back side edge 8 side is removed by the thickness of the riser plate 4, the lower end portion 18 of the riser plate 4 is sandwiched between the decorative plate 8 and the sasara girder 2. Edge 8 on the back side
It is placed on the upper surface 9 of the stepped substrate 6. That is, the lower end of the riser plate 4 is pinched and fixed to the vertical surface 19 of the sassar girder 2 and the rear end surface 20 of the decorative plate 7 of the lower step plate 3.

On the other hand, at the upper end of the riser plate 4, since it is bent outward by the outwardly bent groove section 15, a small square section space 22 is formed between the upper end surface 21 and the lower surface of the step plate substrate 6. Therefore, a reinforcing plug prepared in advance so as to reinforce the above-mentioned portion 17 of the decorative sheet 12.
23 is embedded in this space 22.

In this way, the upper end of the riser plate 4 is reinforced and the lower end is securely attached.

In this embodiment, since the stair-like member 1 is used as described above, the step plate 3 completed by adhering and covering the decorative plate 7 on the step plate substrate 6 is completed.
When the riser plate 4 is connected to the predetermined position and the step plates 3 are sequentially placed from above the sasara girder 2 as described above,
The riser plate 4 is also arranged at the same time, and the step plate 5 is almost completed.

Further, the cutting process of the dissolution member 1 and the sticking and coating of the decorative plate 7 portion on the stepped substrate 6 can be carried out at the factory, which is extremely convenient. That is, the cutting process of the inner bent groove-shaped cross section 14 and the outer bent groove-shaped three faces 15 can be performed with high accuracy and high speed by a factory processing machine, and the adhesive coating of the decorative plate 7 portion can be efficiently performed. . Further, as shown in FIG. 3, the riser plate 4 connected to the completed step plate 3 can be laid down on the lower surface 11 of the step plate substrate 6 of the step plate 3 to form a single plate. As a result, it is very convenient for storage, transportation, and horizontal holding. At the construction site, since the stairs 5 are almost completed with the above-mentioned work length, workability is good and it can be carried out easily in a short time.

<Effect of the Invention> According to the present invention, a riser plate is formed by connecting the decorative plates constituting the step plate continuously, and the upper and lower ends of the riser plate are reinforced and sandwiched respectively, so that the riser plate made of a decorative plate is inserted. Even a plate will be sufficiently durable.
