Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to an assembly structure for stairs provided at a stepped portion of a floor surface.

(Prior art) As a conventional staircase assembly structure, for example,
The one shown in the figure is known.

In this conventional staircase assembly structure, there is a horizontal crosspiece in the center of the step vertical surface 03 between the upper floor surface 01 and the lower floor surface 02.
4, and a longitudinal frame member 05 is erected on the lower floor surface 02 facing the stepped vertical surface 03,
A step board 06 was installed on the upper surface of the horizontal beam 04 and the frame material 05.

In addition, between the upper floor surface 01 and the tread plate 06, the tread plate 0
There are risers 0 between 6 and the lower floor surface 02, respectively.
7 and 08 are provided, and frames 09 and 010 are provided above the risers 07 and 08, respectively.

(Problems to be Solved by the Invention) However, in such a conventional staircase assembly structure, the width of the staircase 011 is formed to be approximately the length of the frame material 05, so that the width of the staircase 011 is approximately the same as the length of the frame material 05. stairs 011
There was a problem in that only one width of the frame material 05 could be formed, and frame members 05 of different lengths had to be formed to correspond to the respective staircase widths.

Furthermore, since the tread plate 06 is supported by two surfaces, the horizontal beam 04 and the upper surface of the frame material 05, with the tread plate 06 of a constant thickness, the strength of the stair 011 decreases as the width of the stair 011 increases. .

Therefore, in order to maintain strength, it was necessary to consider the thickness of the tread 06 in accordance with the width of the stairs 011.

(Means for Solving the Problems) The present invention has been made for the purpose of solving the above-mentioned problems. In a stair assembly structure in which a tread is provided on the upper surface of the frame material, a plurality of the frame materials are arranged in a direction perpendicular to the vertical surface of the step and at predetermined intervals along the vertical surface of the step. I placed them.

(Function) Therefore, in the staircase assembly structure of the present invention,
By arranging a plurality of frame materials at predetermined intervals in a direction perpendicular to the vertical plane of the step on the floor surface of the frame material and along the vertical surface of the step, the length of the frame material can be easily adjusted without changing the length of the frame material. Depending on the number of stairs, various widths can be formed, and the strength of the stairs can be maintained without changing the thickness of the treads.

(Example) Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

First, the configuration of the first embodiment shown in FIGS. 1 and 2 will be explained.

1 is an upper floor surface, 2 is a lower floor surface, and a staircase 3 is provided at a step portion.

This staircase 3 includes a plurality of frame members 4 erected on a lower floor surface 1, and treads 5 provided on the upper surface of the frame members 4.
, a riser board 6 provided at the riser part of the stepboard 5 and the lower floor surface 1, and a stair stile 7 provided at the upper end of the riser board 6.

The frame material 4 is composed of a vertical bar 8 and a horizontal bar 9 made of wood, and a reinforcing bar 10 provided on the side surface of the horizontal bar 9, and the tread plate 5 is arranged approximately at the center of the step vertical surface 11. formed in height.

In addition, this frame material 4 has the horizontal bar 9 provided with the reinforcing bar 10 located below, and is perpendicular to the stepped vertical surface 11 between the upper floor surface 1 and the lower floor surface 2, and They are arranged at a predetermined interval t along the stepped vertical surface 11 and are fixed to a substrate 12 on the lower floor surface 1 and a wooden frame 13 provided on the stepped vertical surface 11.

14 is an upper riser board, 15 is an upward stile,
The upper riser board 14 is fixed to a wooden frame 13 provided on the step vertical surface 11.

The step board 5 is made of particle board, the riser board 6 and the upper riser board 14 are made of plywood, and a carpet 16 is pasted on the surfaces of these boards.

Note that 17 is an upper floor plate and 18 is a lower floor plate, which are fixed to the upper floor surface 1 and the lower floor surface 2, respectively.

Next, the operation of the embodiment will be explained.

When assembling the stairs 3 to the step part between the upper floor surface 1 and the lower floor surface 2, first place the frame material 4 on the step vertical surface 1.
The wooden frame 13 and the board 12 are arranged in a direction orthogonal to 1 and at a predetermined interval t along the vertical plane 11 of the step, and the number of wooden frames 13 and the board 12 are arranged in accordance with the width of the stairs using screws or the like.
Fixed to.

Although the distance t depends on the strength of the frame material 4, it is appropriate to set it to around 30 cm.

Next, the step board 5 is fixed to the upper surface of the frame member 4. After fixing the riser board 6 to the frame material 4 and the upper riser board 14 to the wooden frame 13, the stair stile 7 is fixed to the frame material 4 and the ascending stile 15 to the wooden frame 13.

Finally, step board 5, riser board 6, upper riser board 1
A carpet 16 is attached to the surface of the stairs 3, and the assembly of the stairs 3 is completed.

Therefore, in the staircase assembly structure of the embodiment of the present invention, the width of the stairs can be accommodated by the number of frame members 4 without changing the length of the frame members 4, and the width of the stairs can be adjusted by changing the number of frame members 4.
The strength of the stairs 3 can be maintained without changing the thickness of the stairs.

Next, a second embodiment shown in FIG. 3 will be described.

In this embodiment, the stair stile is integrally formed with the tread 19, and the surface of the stair 3 is finished with wood.

Note that other configurations and operations are the same as those of the first embodiment shown in FIGS. 1 and 2, so the same reference numerals are given to the drawings and omitted.

Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to these embodiments, and the present invention may be modified without departing from the gist of the present invention. included.

For example, the material of the frame material is not limited to wood, but may also be made of metal.

(Effects of the Invention) As explained above, in the staircase assembly structure of the present invention, the frame material is installed in a direction perpendicular to the vertical plane of the step on the floor and along the vertical plane of the step. By arranging multiple pieces at predetermined intervals, it is possible to create various widths of stairs by changing the number of frame materials without changing the length of the frame materials, and it is also possible to create various widths of stairs without changing the thickness of the treads. The effect is that strength can be maintained.
