When installing such a staircase unit, the adjusting members 54, 54 are attached to the wall 5 with adhesives 55, 55.
Bonded to 1,51. The gypsum boards 56, 56 stretched inside the walls 51, 51 are dropped on the adjusting members 54, 54.

[0006]

However, when installing a step member having a unit including at least a side girder, if the inner dimension between the walls is small, it is difficult to insert the step unit between them. there were.

That is, when the inner dimension between the walls is small, as shown in FIG.
In the example of the side girder fixed structure shown in FIG.
Since the unitized staircase member is dropped between the walls 51, 51 while rubbing the portions of the adhesive 55, 55 applied to the, the adhesive effect cannot be expected so much.

Therefore, an object of the present invention is to provide a side girder fixing structure for stairs which can absorb the dimensional error between the side girder integrated with the step plate and the wall and can securely fix the side girder to the wall. To do.

[0009]

In order to solve the above-mentioned problems, the invention according to claim 1 is a side girder fixing structure of a stair for fixing a side girder integrated with a step plate to a wall, which is received on the wall. A material is fixed, the side girder is placed on the receiving material, and the side girder is fixed to the receiving material via a connecting member.

The invention according to claim 2 is based on claim 1.
In the invention described above, the connecting member is characterized by a pair of fixed metal parts fixed to the side girder and the receiving member respectively, and a bolt and a nut for connecting the pair of fixed metal parts to each other.

Further, the invention according to claim 3 is based on claim 2.
In the invention described above, the coupling holes of the pair of fixed metal objects are elongated holes.

[0012]

According to the first aspect of the present invention, the side girder integrated with the step plate is placed on the receiving member fixed to the wall, and the side girder is fixed to the receiving member via the connecting member. Therefore, for example, even when the inner dimension between the walls is small, the portion to which the adhesive is applied is not rubbed against the wall, and the dimensional error between the side girder integrated with the step plate and the wall is absorbed, The side girder can be securely fixed to the wall via the receiving member and the connecting member.

According to the second aspect of the present invention, a pair of fixing hardware fixed to the side girder and the receiving member are bolts and
Since the nuts are connected to each other, the side girders can be easily and surely fixed to the receiving member.

Further, according to the third aspect of the present invention, since the pair of fixing holes for the fixed hardware are elongated holes, the bolts and nuts can be connected while absorbing the dimensional error.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a side girder fixing structure for stairs according to the present invention will be described below with reference to FIGS.

First, FIG. 1 shows a side girder fixing structure of a staircase as an example to which the present invention is applied. 1 is a wall, 2 is a step plate, 3 is a side girder (sasara girder), 4 is a nail, 5 Is an adjusting material, 6 is a receiving material, 7 is an adhesive, and 21 is a gypsum board. Side girders (Sasara girders) 3 and 3 are integrally provided on both sides of the step plate 2 by coupling with nails 4 and 4 to form a unit, and adjusting members 5 and 5 are provided on outer side surfaces of the side girders 3 and 3. Are united together.

When installing such a staircase unit, the receiving members 6 and 6 are attached to the walls 1 and 1 in advance by the adhesive 7,
7 and the screw nails 8, 8 ... Are hammered in and fixed as shown in the enlarged view of FIG. In FIG. 2, the wall 1 is composed of a wall panel, and the wall panel 1 has vertical and horizontal core members 1b between the front and back plywoods 1a.

Here, the adhesive 7 is applied to the side surface and the upper surface of the receiving material 6. Further, as shown in FIG. 4, the receiving member 6 has a length and shape corresponding to the length of the staircase unit to be installed.

Then, the staircase unit is dropped between the walls 1 and 1 to which the receiving members 6 and 6 are fixed, and the side girders (Sasara girders) 3 and 3 and the adjusting members 5 and 5 are receiving members 6 and 6. Put each on top of 6. By this, side girder (Sasara girder) 3
The adjusting material 5 is adhered onto the receiving material 6 with the adhesive 7, and the side girders (Sasara girders) 3 are fixed to the receiving material 6 by the connecting member 10, as shown in FIG.

That is, the connecting member 10 is composed of a pair of fixed hardware 1.
1, 11, bolts 17, and nuts 18. The fixed hardware 11 is L-shaped when viewed from the side, and as shown in FIG.
A plurality of L-shaped fixed pieces 12 (four pieces in the figure)
Fixing holes 13, 13, 13, 13 are formed, and a connecting hole 15 is formed in the other L-shaped connecting piece 14 by a long hole extending in the direction perpendicular to the fixing piece 12.

When fixing the fixing hardware 11 to the side girders 3, as shown in FIG. 2, the fixing piece 12 is fixed in the fixing holes 13, 13, 13, 13 as shown in FIG. The nails 16, 16, 16, 16 are attached to the side girder 3 and the adjusting member 5.
It is done by driving up to. Further, when fixing the fixed hardware 11 to the receiving member 6, as shown in FIG.
The fixing piece 12 with the fixing holes 13, 13, 13,
In 13, the nails 16, 16, 16, 16 are driven into the receiving member 6 to carry out.

As shown in FIG. 2, the fixed metal parts 11, 11 fixed to the side girder 3 and the receiving member 6 in this way are connected by the elongated holes of the connecting pieces 14, 14 as shown in FIG. In, the nuts 18 are tightened through the bolts 17 so as to be coupled and fixed to each other. As shown in the drawing, the plaster board 21 stretched inside the wall 1 is dropped on the adjusting material 5, and the decorative step board 22 is stuck on the step board 2, and at the side thereof. Gypsum board 21
A skirting board 23 is attached to the surface.

By using the support member 6 in this manner, the dimensional error between the side girder 3 integrated with the step plate 2 and the wall 1 is absorbed,
The side girder 3 can be securely fixed to the wall 1 via the receiving member 6 and the connecting member 10.

As described above, according to the side girder fixing structure of the stairs according to the present invention, for example, even when the inner dimension between the walls 1 and 1 is small, the adjusting agent adhesive is applied as in the conventional case. Since no part is rubbed against the walls 1 and 1, stairs can be easily constructed even after all the walls have stood up.

In the above embodiment, the side girder 3 is placed on the receiving member 6 and the fixed metal piece 11 is attached later. However, the present invention is not limited to this, and the receiving piece may be received in advance. The fixed hardware 11 may be attached to the material 6 and the side girder 3, respectively. In addition, the structure of stairs and its installation location are arbitrary, and the side girders do not have to be sasara girders, and the fixing of the receiving material does not have to be performed by adhesion. Of course, it can be changed appropriately.

[0026]

As described above, according to the side girder fixing structure for stairs according to the invention described in claim 1, the side girder integrated with the step plate is placed on the receiving member fixed to the wall, By fixing this side girder to the receiving member via the connecting member, for example,
Even if the inner dimension between the walls is small, it is possible to absorb the dimensional error between the side girder integrated with the step plate and the wall, because the portion where the adhesive is applied does not rub against the wall. The side girder can be securely fixed to the wall via the receiving member and the connecting member.

According to the side girder fixing structure for stairs according to the second aspect of the present invention, a pair of fixing hardware fixed to the side girder and the receiving member are fixed to the wall by connecting them with each other with bolts and nuts. The side girder can be easily and surely fixed to the receiving material.

Further, according to the side girder fixing structure for stairs according to the third aspect of the present invention, since the pair of fixing holes of the fixing metal members are elongated holes, the bolts are absorbed while absorbing the dimensional error.
It can be connected by a nut.
