Description

[Detailed explanation of the idea] 【Technical field】

The present invention relates to a structure for attaching a spar adapter, which is a decorative material, to the upper end of a stringer of a staircase.

[Background technology]

Conventionally, a stringer adapter having the same thickness as the stringer was glued to the upper end surface of the stringer, and the stringer adapter was fixed by driving nails from the stringer adapter to the stringer. Therefore, when gluing the girder adapter onto the stringer, it is difficult to position the girder adapter, making installation difficult, and there is also a risk that the girder adapter may shift during nailing or curing of the adhesive. It was hot.

[Purpose of the invention] The present invention was made in view of the above-mentioned technical background, and its purpose is to facilitate the work of attaching a girder adapter to a stringer.

[Disclosure of invention]

The structure for attaching the inventive girder adapter to the stringer is such that adapter side plates 3 and 4 are provided on both sides of the adapter body 2, which has the same thickness as the stringer body 1, to form the girder adapter 5. Attach the lower ends of the side plates 3 and 4 to the adapter body 2.
The lower surface of the adapter main body 2 is placed on the upper surface of the stringer main body 1, and the upper end of the stringer main body 1 is held between the lower ends of the adapter side plates 3 and 4. glue 6
It is characterized in that it is fixed by means of fixing means such as nails 7 or the like. Since the lower ends of the adapter side plates 3 and 4 provided on both sides of the adapter main body 2 are made to protrude below the lower surface of the adapter main body 2, the upper end of the stringer main body 1 is held by the spar adapter 5. This allows the girder adapter 5 to stand on its own on the stringer main body 1, and also enables positioning of the girder adapter 5 in the width direction. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 2 shows the upper end of the stringer 8 and the stringer adapter 5. The stringers 8 are arranged on both sides of the tread from the bottom end to the top end of the staircase, and a decorative board 9, which is one size smaller than the stringer main body 1, is provided on the surface of the stringer main body 1, which has a certain thickness. The upper end surface of the stringer main body 1 and the upper end surface of the decorative board 9 are formed horizontally, and the upper end surface of the decorative board 9 is lower than the upper end surface of the stringer main body 1. A notch 12 is provided at the front corner of the holder. Moreover, this stringer main body 1 is constructed with a gap 11 of a constant width between its back surface and the wall surface 10. Further, the girder adapter 5 has adapter side plates 3 and 4 attached to both sides of the adapter body 2, as shown in FIG. The adapter main body 2 has the same thickness as the stringer main body 1 and has a trapezoidal shape, the upper and lower surfaces are horizontal surfaces, the lower surface is formed to have the same dimensions as the upper surface of the stringer main body 1, and the front surface is flat. It is inclined at the same inclination as the girder body 1. Also,
One adapter side plate 3 has the same thickness as the decorative board 9, has a trapezoidal shape that is one size smaller than the adapter main body 2, and is made of the same material as the decorative board 9. The other adapter side plate 4 has a vertically long rectangular shape, and the lower end portions of both adapter side plates 3 and 4 protrude below the lower surface of the adapter body 2. Therefore, this girder adapter 5 is constructed as follows. First, in the state in which the stringer 8 is constructed, the upper end of the stringer 8 slightly protrudes above the landing 13, as shown in FIG. After applying adhesive 6 to the upper surface of the stringer main body 1 and the upper surface of the decorative board 9, the lower end of the adapter side plate 4 is inserted into the gap 11 between the stringer main body 1 and the wall surface 10. The upper end of the stringer main body 1 is held between the lower ends of the side plates 3 and 4, and the lower surface of the adapter main body 2 is placed and glued on the upper surface of the stringer main body 1, and the lower surface of the adapter side plate 3 is attached to the upper surface of the decorative board 9. Place and glue. At this time, since the girder adapter 5 is holding the upper end of the stringer main body 1, it is positioned in the lateral direction, and all that is required is to align the inclined surface of the stringer main body 1 and the sloped surface of the adapter main body 2. Therefore, the position of the girder adapter 5 can be easily adjusted to avoid twisting. After this, from the adapter body 2 to the stringer body 1
The girder adapter 5 is fixed by driving nails 7 diagonally to the girder.Since the girder adapter 5 holds the stringer main body 1, it can stand on its own and will not shift when nailing. It is easy to do. Furthermore, as shown in FIG.
Adhesive 6 is applied to the upper surface, the back surface and the sloped surface, the sloped surface of the stringer main body 1, and the top surface, back surface and sloped surface of the adapter side plate 3. After this adhesive 6 is applied, a frame-shaped cloth sill 14 having an L-shaped cross section is attached along the edges of the adapter body 2 and stringer body 1, and the cloth sill 14 is fixed with hidden nails 15. In this way, the edges of the girder adapter 5 and the stringer 8 are decorated with the woven fabric 14, and the gap 11 between the stringer main body 1 and the wall surface 10 is also covered with the woven fabric 14.
4. Further, the cloth sill 14, the adapter side plate 3, and the decorative board 9 are flush with each other, but a groove 15 is formed between the decorative board 9 and the cloth sill 14.
Finally, as shown in FIG. 4, decorative baseboards 16, curtain panel parting members 17, interior decorative curtain panels 18, etc. are attached to the landing 13 and wall surface 10, and the exterior is constructed as shown in FIG. 5.

[Effect of the idea]

As described above, in the present invention, the lower ends of the adapter side plates provided on both sides of the adapter body are made to protrude below the lower surface of the adapter body, so that the upper end of the stringer body can be held between the spar adapters. The adapter can stand on its own on the stringer body, and the adapter on the stringer can be positioned in the width direction, and the advantage is that it is easy to fix the adapter on the stringer with adhesive or nails. There is.
