Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method for reforming stairs.
[0002]
OBJECT OF THE INVENTION
An object of the present invention is to provide a method for renovating an existing stairs to a safer one while making the renovation work easier.
[0003]
[Means for Solving the Problems]
In order to achieve the above object, the present invention employs the following means.
The invention according to claim 1 is a staircase having a pair of left and right side girders, a tread board laid between the pair of side girders, and a kick board installed on the front lower side of the vertical rear surface of the protruding nose portion of the tread board. against, as the decorative riser plate rear surface serving as the projecting nosing of the vertical rear surface flush with or substantially flush, is for fixing to the riser plate via a spacer member.
[0004]
【The invention's effect】
The present invention has the following effects by the configuration as described above.
According to the invention of claim 1 , the decorative kick plate is fixed to the kick plate via the spacer material so that the vertical rear surface of the protruding nose portion of the tread plate and the rear surface of the decorative kick plate are flush or substantially flush with each other. Since the inward side surface of the side flange below the protruding nose portion of the tread board is concealed by the makeup kick plate, it is possible to save the trouble of making up the inward side surface of the side cover. In addition, the surface and a rear surface of the vertical rear surface of the projecting nosing of the step board and the decorative riser plate that Do flush or substantially flush, it ranks Personality toe such that dangerous when projecting nosing of step board Absent.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the invention will be described below.
In this description, “front” refers to the right side of FIG. 1, “rear” refers to the left side, “left” refers to the back side of FIG. 1, and “right” refers to the front side.
[0006]
The stairs 1 at the time of completion were formed so as to face each other inwardly facing side surfaces 3a of a pair of left and right side hooks 3 attached to the left and right side walls 2 of the building and the left and right side hooks 3 Downward and rightward or right or left formed so as to face each other inwardly facing side surfaces 3a of the tread plate 6 fitted in the tread plate insertion groove 5 opened to the front and right or left and the left and right side hooks 3. It has a kick plate 8 fitted in a kick plate insertion groove 7 opened to the left.
[0007]
The staircase 1 is reformed as follows.
[0008]
[First step]
The decorative kick plate 10 is cut so that the left-right width is “L” (see FIG. 2) and the vertical length is “M” (see FIG. 1). Thereafter, at least one, and in this embodiment, four spacer members 11 are provided so that the rear face 10a is flush with or substantially flush with the vertical rear face 9a of the protruding nose portion 9 of the tread board 6. It is attached to the kick plate 8 via (for example, made of square bar or the like).
As is apparent from this explanation, the decorative kick board 10 is of a large shape having a cut-out portion so as to correspond to the stairs 1 (the kick board 8) at most construction sites when shipped from the factory. In addition, the member demonstrated below is similarly made into the large or long shape which has a part to cut off.
The pasting is performed by a known fixing means such as an adhesive or a nail.
[0009]
[Second step]
After cutting the decorative tread 13 so that the left-right width is “L” and the front-rear length is “N” (see FIG. 1), the decorative tread 13 is attached to the tread 6 so as not to cover the upper surface of the protruding nose portion 9. The
N = Q−O−P (see FIG. 1)
[0010]
[Third step]
The unit decorative side plate 16 has a shape corresponding to one step of the staircase 1 as shown by the solid line in FIG. 4 and is attached to the inward side surface 3a of the side 3 that touches the human eye. Reference numeral 16 a denotes an inclined upper edge of the unit decorative side plate 16, 16 b denotes a horizontal edge of the unit decorative side plate 16, and 16 c denotes a vertical edge of the unit decorative side plate 16.
Note that when the operator (carpenter) cuts the unit decorative side plate 16, once the unit decorative side plate 16 is cut into small pieces, the cut unit decorative side plate 16 cannot be used. 16 has a tendency to cut slightly larger, and therefore, the inclined edge 16a of the unit decorative side plate 16 after most cutting projects from the inclined upper surface of the side 3.
[0011]
[Fourth step]
The nose decoration material body 22 is cut so that the left and right length is “R” (see FIG. 2), and is pasted on the protruding nose portion 9 of the tread board 6. Thereafter, the anti-slip material 23 is cut so that the left and right lengths are “R” (see FIG. 2), and attached to the recess 24 of the nose decoration material body 22.
[0012]
[Fifth step]
The long decorative material 26 in which the groove 27 into which the inclined upper edge 16a of the unit decorative side plate 16 is fitted is formed on the lower surface so that the inclined upper edge 16a of the unit decorative side plate 16 is fitted into the groove 27. And the unit decorative side plate 16 are attached to the inclined upper surface.
The long decorative material 26 is stretched sequentially from the bottom, and the long decorative material 26 attached to the top is cut into a length corresponding to the remaining side 3.
[0013]
[Modifications]
A description will be given below of modifications and the like.
(1) The shape of the unit decorative side plate 16 is not limited to that of the embodiment.
(2) The shape of the side 3 is arbitrary.
[Brief description of the drawings]
FIG. 1 is a longitudinal sectional view of an essential part of a staircase reformed by a method according to an embodiment of the present invention.
2 is a cross-sectional view of intermediate omission along line II-II in FIG. 1;
FIG. 3 is a cross-sectional view of intermediate omission along line III-III in FIG.
FIG. 4 is a side view showing a unit decorative side plate.

Claims (1)

For a staircase having a pair of left and right side girders, a tread board laid between the pair of side girders, and a kick board installed on the front lower side of the vertical rear surface of the protruding nose of the tread board, a decorative kick board is provided. as subsequent surface becomes the protruding nosing of the vertical rear surface flush with or substantially flush, remodeling method of stairs is fixed to the riser plate via a spacer member.
