Abstract

PROBLEM TO BE SOLVED: To simplify execution and protect a decorative surface from being damaged by providing tread bed material, decorative material attached to the tread bed material, a groove formed to be extended on the upper face of the tread bed material in the width direction, and a rib formed to be extended on the lower face of decorative material in the width direction and fitted to the groove. SOLUTION: When a staircase 10 is to be assembled, two open strings 16 are set to attach a riser 14 to the vertical part 16a of the open string 16. The upper end of the riser 14 is fitted to the groove 24 of bed material 18 to fix the bed material 18 on the horizontal part 16b of the open string 16 by nails. Decorative material 20 is attached to the bed material 18 in the final stage of construction work. At this time, an adhesive is applied on the decorative material 20 and the bed material 18, a locking part 20b is locked to the front end of the bed material 18 to fit each rib 26 to corresponding grooves 22, and the bed material 18 and the decorative material 20 are adhered to each other. Accordingly, execution is improved, curing labor is saved, and the decorative face can be protected from being damaged.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a staircase, and more particularly to a staircase assembled in a building, for example.

[0002]

2. Description of the Related Art In a conventional staircase, a tread having a decorative material previously bonded to a base material has been used.

[0003]

In the prior art, a tread having a decorative material adhered to a base material in advance is used.
When fixing the footboard to the slab, it is necessary to go under the stairs and nail upwards from the back side of the footboard in order to prevent the surface (decorative surface) of the decorative material from being damaged. There was a problem that was bad. Also, using the stairs after attaching the treads, or working around the stairs, may damage the makeup surface, so the treads must be cured, which is troublesome. .

[0004] Therefore, a main object of the present invention is to provide a staircase which can be easily constructed and can prevent the decorative surface from being damaged.

[0005]

SUMMARY OF THE INVENTION The present invention relates to a footboard base material, a decorative material mounted on the footboard base material, a groove formed in the upper surface of the footboard base material to extend in the width direction, and a bottom face of the decorative material. 9 is a staircase having a rib formed to extend in the width direction and fitted in the groove.

[0006]

[Function] Since the decorative material can be reliably positioned on the tread base material by fitting the groove and the rib, only the tread base material is nailed to the slab girder first, and the tread plate is provided at the final stage of the construction work. A decorative material can be mounted on the base material. Therefore, when nailing the tread base material to the sasara girder, a nail can be driven from the upper surface side of the tread plate base material.

[0007]

According to the present invention, it is possible to easily position the decorative material and to nail the tread base material from the upper surface side thereof, so that the workability can be improved. In addition, since the decorative material is attached to the base material at the final stage of the construction work, it is possible to save time for curing and prevent the decorative surface from being damaged.

The above objects, other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT The staircase 10 of this embodiment shown in FIG. The step board 12 includes a step board base material 18 made of wood or the like and a decorative material 20 made of aluminum or resin (extrusion molding) or the like. The base material 18 is formed in a plate shape having substantially the same width as the width of the stairs 10, and two grooves 22 for positioning the decorative material 20 on the base material 18 are formed on the upper surface of the base material 18 in the width direction. It is formed to extend. Also, on the lower surface of the base material 18,
A groove 24 having a width slightly larger than the thickness of the embedding plate 14 is formed to extend in the width direction (longitudinal direction). On the other hand, the decorative material 20 includes a plate-shaped main body 20a having substantially the same width as the width of the base material 18, and a rib 26 fitted in the groove 22 of the base material 18 is provided on the lower surface of the main body 20a in the width direction. It is formed to extend. Further, a substantially L-shaped locking portion 20b extends downward from one end (front end) in a direction (front-back direction) orthogonal to the width direction of the main body 20a. The vertical length of the locking portion 20b is set to be substantially the same as the thickness of the base material 18.

[0010] The embedding plate 14 includes a plate-like base material 14a made of wood or the like and having substantially the same width as the width of the stairs 10. Aluminum or resin (extrusion molding) is provided on the front main surface of the base material 14a. The decorative material 14b made of, for example, is adhered. The base material 14a and the decorative material 14b are integrally formed in a factory in advance. Sasara girder 16 is made of wood or the like, and is formed in a substantially saw blade shape by repeating vertical portions 16a and horizontal portions 16b. The height of the vertical portion 16a is slightly lower than the height of the recessed plate 14, and the length of the horizontal portion 16b in the front-rear direction is slightly shorter than the length of the stepping plate 12 in the front-rear direction.

When assembling the stairs 10, first, two slabs 16 are installed at predetermined positions in the building at the same interval as the width of the stairs 10. Subsequently, the embedding plate 14 is attached to the vertical portion 16a of the slab 16 with the decorative material 14b facing the front side. Then, as shown in FIG. 2, the base material 18 is fixed to the horizontal portion 16 b of the slab girder 16 from the upper surface side of the base material 18 with a nail 28 while the upper end of the sinking plate 14 is fitted in the groove 24 of the base material 18. I do. At the stage where the base material 18 is nailed, the assembling work of the stairs 10 is temporarily stopped. Then, the decorative material 20 is attached on the base material 18 at the final stage of the construction work.

When attaching the decorative material 20, first, an adhesive is applied to at least one of the lower surface of the decorative material 20 and the upper surface of the base material 18. Then, the locking portion 20b is locked to the front end of the base material 18, and each rib 26 is fitted into the corresponding groove 22, and the base material 18 and the decorative material 20 are bonded. According to this embodiment, the nail 28
Is applied to fix the base material 18 to the slab girder 16, so that the work can be easily performed. In addition, the cosmetic material 20
Since there is no need to cure, the labor for curing can be saved. Further, since the rib 26 is fitted into the groove 22, the decorative material 20 can be easily positioned on the base material 18.

Further, even if the adhesion between the base material 18 and the decorative material 20 is released, the decorative material 20 does not slip off from the base material 18 because the groove 22 and the rib 26 are fitted. The numbers and shapes of the grooves 22 and the ribs 26 are not limited to the examples. That is, at least one groove 22 and at least one rib 26 may be formed, and their cross-sectional shapes may be triangular or semicircular.
