(57) [Abstract] [Purpose] A tread plate fixture that prevents the noise of the stairs by fixing the tread plate without weakening the strength of the member that supports the tread and without any special processing. To provide. [Structure] An upper end of a standing fixing piece 3 is laterally extended at a right angle to form a tread support portion 4, and an elastic material 5 is attached to an upper surface of the tread support portion 4.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tread fixing tool for fixing a tread of a stair to a support, a girder, or the like.

[0002]

[Prior Art]

 Conventionally, in order to attach a tread, a sasara girder or a pillar was cut, and the end of the tread was fitted into this cut.

However, according to such a stair fixing method, since the cross-sectional area of the sasara girder or the supporting column becomes small at the cut portion, the cross-sectional performance is deteriorated, and both the angle and the depth are sufficient to form the cut. Since precision is required, it takes a lot of work to process, and since the treads are directly fitted into the notches, squeaking is likely to occur.

[0004]

[Problems to be solved by the device]

 An object of the present invention is to provide a tread plate fixing tool which can easily fix the tread plate without any special processing without weakening the strength of the member supporting the tread plate and preventing the stuttering of the stairs. Especially.

[0005]

[Means for achieving the object]

 In order to achieve the above-mentioned object, the tread fixing device of the present invention forms a tread supporting part by protruding the upper end of the standing fixing piece laterally at a right angle, and at the same time, attach an elastic material to the upper surface of the tread supporting part. .

[0006]

[Action]

 The upright fixing piece comes into contact with the side surface of the supporting member such as a girder or column, and is fixed with a screw, etc., and the tread is placed on the upper surface of the tread supporting part and fixed with a screw, etc., and the tread without cutting is performed. Is attached to the support member, and the elastic material absorbs the shock when going up and down the stairs.

【Example】

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

FIG. 1 shows a tread fixture 1 mainly used for fixing a tread 2 of a straight staircase, which is laterally attached to the upper end of a standing fixing piece 3 made of one flat plate made of metal. A tread supporting part 4 projecting at a right angle is integrally formed, and an elastic material 5 such as rubber or foam synthetic resin is attached to the upper surface of the tread supporting part 4 and the outer surface of the standing fixing piece 3.

The upright fixing piece 3 and the tread support part 4 have a width slightly smaller than the width of the tread 2 or a short length, and the upright fixing piece 3 and the tread support part 4 are provided with fixing holes 10 respectively. It is set up.

Further, the elastic member 5 on the outer surface of the upright fixing piece 3 can be omitted.

In order to attach the tread plate 2 using the tread plate fixing tool 1, as shown in FIG. 2, the upright fixing piece 3 is brought into contact with the side surface of the supporting member 6 such as a saw girder, and the screw or the like is passed through the fixing hole 10. The fixing tool 7 is driven and fixed, the tread plate 2 is placed on the upper surface of the tread supporting part 4, and the fixing tool 7 such as a screw is fixed from the rear surface through the fixing hole 10.

When the riser plate 8 is provided, as shown in FIG. 3, since the riser plate 8 is erected on the tip of the lower surface of the tread plate 2, the tread plate fixture 1 is hidden and invisible from the outside.

FIG. 4 shows a tread plate fixture 1 ′ used for fixing the tread plate 2 in the surrounding portion of the staircase, in which the standing fixing piece 3 is made of a metal plate bent at a right angle to have an L-shape in plan view. The tread support portion 4 which is laterally extended from the upper end of the fixing piece 3 is also bent in an L shape in plan view.

Further, it is preferable to prepare two types of the tread support portions 4, that is, one that projects to the outer corner side of the upright fixing piece 3 and one that projects to the inner corner side.

Since other configurations are the same as those of the embodiment shown in FIG. 1, the same parts are denoted by the same reference numerals and the description thereof will be omitted.

Next, a turning staircase constructed using the tread fixture 1 shown in FIG. 1 and the tread fixture 1 ′ shown in FIG. 3 will be described.

As shown in FIG. 5, a tread plate fixture 1 ′ a that a tread support part 4 projects to the outside corner side is used on the narrow side of the tread 2 in the surrounding part where the wall surface bends at a right angle. On the wide side of the stepping plate fixing tool 1'b, the stepping plate supporting portion 4 extends to the inner corner side.

Then, the bent two pieces of the upright fixing piece 3 of the tread fixing tool 1 ′ a are brought into contact with the outer surface of the corner portion of the column 9 and fixed by the fixing tool 7 through the fixing holes 10, and are orthogonal to each other on the wall surface side. The bent two pieces of the upright fixing piece 3 of the tread plate fixing tool 1'b are brought into contact with the side surfaces of the supporting members 6, 6'to be fixed and similarly fixed by the fixing tool 7, and these tread plate fixing tools 1'a, 1 '. Both ends of the tread plate 2 are placed on the upper surface of the tread support part 4 of b, and the fixing tool 7 is screwed and fixed from the back surface through the fixing holes 10.

In the portion where the wall surface is flat, the upright fixing piece 3 of the tread fixing tool 1 shown in FIG. 1 is brought into contact with the outer surface of the column 9 and the side surface of the supporting member 6, respectively, and the same as in the straight staircase shown in FIGS. 2 and 3. Attach tread 2 to.

Even in the surrounding area, two tread fixtures 1 shown in FIG. 1 are used without using the L-shaped tread fixture 1'in plan view, and these tread fixtures 1 are used on the side surfaces of the support members 6 and 6 ', respectively. The tread 2 can be fixed by mounting them so that they are orthogonal to each other.

In addition, even if the length of the tread fixing tool 1 is slightly long, if the remaining part is made to project to the far side of the slope, it will not be visible from the front of the stairs, so there will be many types of tread fixing with different lengths. It is not necessary to prepare the ingredient 1.

[0022]

[Effect of the device]

 As described above, according to the tread fixing device of the present invention, the tread can be fixed without making a cutting process on the supporting member such as a girder girder or a column, so that the cross-sectional performance of the supporting member is deteriorated. There is no need to worry, the work of supporting members can be saved, and work efficiency is greatly improved.

Further, since the support member and the tread are not directly fitted, and the elastic material absorbs the shock when moving up and down, it is possible to prevent squeaking.
