DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an example of a fixing fitting used for a staircase structure according to the present invention. This fixing bracket A
Is composed of a substantially flat columnar member mounting piece 1, a substantially rectangular parallelepiped cushioning material 2, and a side plate mounting piece 3 having an L-shaped cross section with a side plate mounting surface 3a and a cushioning material mounting surface 3b. Material mounting piece 1
And the side plate mounting surface 3a of the side plate mounting member 3 is orthogonally fixed, and the cushioning material 2 is interposed between the pillar mounting member 1 and the cushioning material mounting surface 3b of the side plate mounting member 3 and fixed by an adhesive or the like to be integrated. It is something that becomes. A plurality of mounting holes 4a and 4b are formed in the side plate mounting surface 3a of the column material mounting piece 1 and the side plate mounting piece 3, respectively.

As shown in FIG. 1, it is preferable to bend one end of the column material mounting piece 1 at a right angle so as to be substantially parallel to the side plate mounting surface 3a to form a bent end portion 1c.
In some cases, the bent end portion 1c may be omitted, and the bent end portion 1c may be used as a simple flat plate-shaped mounting member 1.

In order to fix the side plate 5 of the stairs to the column member 6 by using the fixing bracket A, as shown in FIGS. 2 and 3, a tread plate and a riser plate ( (Not shown) are attached to the side plate 5 and the column member 6 at a predetermined position in the frame so that a gap S is provided between the side plate 5 and the column member 6 when the metal member A is fixed with the fixing bracket A. The side plate mounting surfaces 3a of the column member mounting pieces 1 and the side plate mounting pieces 3 of the fixing bracket A are respectively positioned on the column members 6 and the side plates 5 respectively.
Is fixed with wood screws or the like (not shown) through the mounting holes 4a and 4b.

When the bent end 1c is formed on the column mounting piece 1 of the fixing bracket A, the bent end 1c is aligned with the corner of the column 6 and the side plate 5 is connected to the column 6 And is fixed using a wood screw or the like via the mounting hole 4a, and then the side plate mounting surface 3a of the side plate mounting piece 3 is brought into contact with the side plate 5 so that the wood screw or the like is inserted through the mounting hole 4b. And fix it (see FIG. 3). By adopting such a fixing method, even if the distance between the column member 6 and the side plate 5 is deviated from a plan in a state where the stairs are arranged in the frame, when the stairs are fixed by the fixing bracket A, these are automatically set. A predetermined gap S can be secured between them.

As shown in FIG. 3, when the side plate 5 is fixed to the column member 6 by using the fixing metal A, not only a gap S is provided between them but also the fixing metal A Between the bent end 1c of the column mounting piece 1 and the side plate 5,
Further, it is preferable that a slight gap is secured between the cushioning material 2 and the side plate 5. For this reason, in the fixing bracket A, the bent end 1 c and the tip of the cushioning material 2 are attached to the side plate mounting surface 3.
It is provided so as to be a position slightly retracted from a. Thereby, the shock or vibration of the side plate 5 when going up and down the stairs is not directly transmitted to the column member 6, and the buffer member 2 can receive a sufficient buffering action.

FIG. 4 shows another example of a fixing member used in the staircase structure of the present invention. The fixing member B has a column member mounting piece 1 'and a side plate mounting piece having substantially the same L-shaped cross section. 3 '
And a cushioning material 2 ', and the column material mounting piece 1' and the side plate mounting piece 3 'are attached to the side plate mounting surface 3a' and the cushioning material mounting surface 3b 'with an L-shaped cross section. 3 ', and the cushioning member mounting surfaces 1b', 1b ', and the side plate mounting surface 3a' of the side plate mounting member 3 are orthogonal to each other. Cushioning material 2 between 3b '
Are fixed and integrated with an adhesive or the like. A plurality of mounting holes 4a ', 4b' are provided on the column mounting surface 1a 'of the column mounting piece 1' and the side plate mounting surface 3a 'of the side plate mounting piece 3', respectively.
Is opened.

In order to fix the side plate 5 of the stairs to the column member 6 using the fixing bracket B, as shown in FIGS. 5 and 6, a tread plate and a riser plate (e.g., between a pair of side plates or one side plate 5). When the side plate 5 and the column member 6 are fixed with the fixing bracket B, a gap S 'is provided between the side plate 5 and the column member 6 at a predetermined position in the shaft assembly. And mounting holes 4a 'and 4b' in the column 6 and the side plate 5, respectively, with the column mounting surface 1a 'of the column mounting piece 1' of the fixing bracket B and the side plate mounting surface 3a 'of the side plate mounting piece 3'. And fix it with wood screws or the like (not shown). Gap S '
Is the side plate mounting surface 3 of the side plate mounting piece 3 'in the fixing bracket B.
a ′ is larger than the plate thickness of the side plate 5 in the staircase structure fixed to the pillar 6 by the fixing bracket B.
Without transmitting the shock and vibration of the
The buffering action of the above allows sufficient buffering.

In the fixtures A and B described above, the column mounting pieces 1, 1 'and the side plate mounting pieces 3, 3' can be formed by bending a metal plate.
The column material mounting pieces and the side plate mounting pieces are integrally bonded and fixed with a buffer material therebetween in a state of being bent in advance, thereby forming fixing brackets A and B, or integrally with the buffer material being sandwiched in a flat shape. After bonding and fixing, the two members are bent in a predetermined direction while maintaining the fixed state, thereby obtaining fixing brackets A and B.

As the cushioning materials 2, 2 ', those generally known as anti-vibration rubbers can be used, and the thickness and hardness thereof are determined by the width of the stairs (the distance between the side plates 4, 4 or the width of a tread plate or a riser plate).
It can be appropriately selected according to the length and length (length of the side plate).

In the present invention, any of the fixtures A and B can be used. However, since the load applied from the side plate 5 to the fixture at the time of ascending and descending the stairs is a downward load, the fixture is bent along this load direction. In the fixing bracket A having the mounting pieces 1 and 3, most of the load (impact) received by the fixing bracket is transmitted to the cushioning material 2 and is effectively absorbed by the cushioning material 2. Is obtained. In the case of the fixing bracket B, since a load is applied in a direction perpendicular to the bending line of the mounting pieces 1 'and 3', these mounting pieces are deformed by an impact and the bending angle is changed. 5 cannot be maintained, and the side plate 5 comes into contact with the column member 6, and the cushioning member 2
May not be able to sufficiently exert the buffering effect of the stiffener. For this reason, in the case of the fixing bracket B, it is necessary to make the thickness of the metal plates of the mounting pieces 1 ′ and 3 ′ larger than that of the fixing bracket A.

[0020]

According to the present invention, the side plate of the stairs and the column are fixed by the fixing fitting having a buffer function, and the stair structure can be obtained without the side plate being in direct contact with the column. Sometimes the impact of stepping on the tread is also absorbed by the shock-absorbing material of the fixing bracket, preventing transmission to the pillars, and also preventing vibration from being transmitted to the entire frame, resulting in noise problems due to ascending and descending stairs. Can be eliminated.
