Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to the structure of a part for attaching the upper part of a stair to the floor of the upper floor.

[Prior Art] Conventionally, an upper frame is integrally formed in advance on the upper part of the stairs, and the stairs integrally formed with the upper frame are attached to the floor portion of the upper floor.

[Problems to be solved by the invention] However, in the above-described conventional example, since the stairs integrally formed with the upper frame are attached to the floor portion of the upper floor, the floor surface of the upper floor is Due to the difference in material thickness of the surface floor material to be finished, it was difficult to construct the upper surface of the surface floor material and the upper surface of the upper frame at the same level.

The present invention was devised in view of the above-mentioned problems of the conventional example, and the purpose thereof is to provide a simple structure for the surface floor material and the stairs even if there is a difference in the thickness of the surface floor material. It is to provide a structure for mounting stairs that can be flush with the upper frame that will be located at the top.

[Means for Solving the Problems] In the staircase mounting structure of the present invention, the upper part of the staircase body 1 is mounted on the floor 2 of the upper floor, and the upper frame 3 separate from the staircase body 1 is mounted.
Is mounted on the upper side of the staircase body 1 and is flush with the upper surface of the upper frame 3 and the upper surface of the surface floor material 4 of the floor 2 of the upper floor. By adopting such a configuration, This is to solve the problems of the conventional example.

[Operation] Then, the staircase main body 1 is attached to the floor 2 of the upper floor, the surface floor material 4 of the floor 2 of the upper floor is constructed, and the upper frame 3 separate from the staircase main body 1 is provided on the upper side of the staircase main body 1. By adjusting the mounting position in the vertical direction, the upper surface of the surface floor material 4 and the upper surface of the upper frame 3 can be installed flush with each other even if the thickness of the surface floor material 4 of the upper floor 2 is different. is there.

[Embodiment] The present invention will be described in detail below based on an embodiment shown in the accompanying drawings.

FIG. 1 shows an embodiment showing the arrangement of stairs according to the present invention. Then, FIG. 2 shows an embodiment in which the floor beams 5 are present on the floor 2 on the upper floor in the X direction of FIG. This floor beam 5 is made of H steel, and the upper flange 5a of the floor beam 5 is
The fixing portion 7 of the stair receiving beam 6 is fixed to the fixing means 8 such as a bolt.
It is stuck in. The staircase receiving beam 6 made of metal has a staircase receiving piece 9 projecting forward from the fixed portion 7, and a hooking piece 10 protruding upward at the tip of the staircase receiving piece 9. In the embodiment shown in FIG. 2, the fixed portion 7 of the stair receiving beam 6 is fixed to the upper horizontal piece 7a, the vertical piece 7b, the upper horizontal piece 7a and the vertical piece 7b at right angles to the upper vertical piece 7a and the vertical piece 7b. The upper horizontal piece 7a of the fixing portion 7 is fixed to the upper flange 5a of the floor beam 5 by the fixing means 8. The staircase body 1 has a tread between the opposing girders 11.
The tread plate 12 and the stepping plate 13 are constructed so as to be installed, and the corner member 14 at each step is attached at the corner formed by the tread plate 12 and the stepping plate 13. A horizontal member 15 is installed between the upper ends of the opposing girders 11. At the upper corners of the horizontal member 15, there are vertically provided elongated fitting grooves 16. Also, the digit
A notch 11a is provided above the fixed portion of the horizontal member 15 of 11. As shown in FIG. 2, the upper frame 3 which is separate from the staircase body 1 is provided with a corner member 14 at the front part of the frame body 3a, and a hanging portion 17 is provided on the side opposite to the corner member 14 of the frame body 3a.
It is configured by hanging. As shown in FIG. 4, both ends of the frame main body 3a project slightly outwardly from both ends of the corner member 14.

Then, in order to attach the staircase main body 1 to the floor 2 portion of the upper floor, the horizontal bridge member 15 installed between the opposing girders 11 on the upper part of the staircase main body 1 is placed on the staircase receiving piece 9 of the staircase receiving beam 6. Along with the hooking piece 10, hook the hooked portion 18 at the lower part of the rear part of the horizontal member 15,
In this manner, the horizontal member 15 is fixed to the floor beam 5 directly or through the stair-receiving beam 6 by the fixing means 19 such as a screw tool or a bolt while the stair body 1 is positioned and supported by the stair-receiving beam 6. is there. After attaching the staircase body 1 in this way,
The upper frame 3 is attached to the upper end of the staircase body 1 and the surface floor material 4 which is a finishing material for the surface of the floor 2 is laid on the floor panel 20 which is the base of the floor 2. In this case, in the upper frame 3, the hanging portion 17 is slidably fitted in the fitting groove 16 of the horizontal member 15 from above and the corner member 14 is fitted horizontally.
Stacked vertically on the front side of 15 and the frame body
Both ends of 3a are slidably fitted vertically into the notch groove 11a of the girder 11, and the mounting position in the vertical direction is adjusted according to the thickness of the surface floor material 4 to be used. The upper surface of the frame 3 is flush with the upper surface.
Then, the fixing means 22 fixes the upper and lower positions. Here, when the thickness of the surface floor material 4 becomes thicker, an adjusting material having an arbitrary thickness is provided between the horizontal frame member 15 and the upper frame 3.
The position of the upper stile 3 is set to a target level by interposing 23. Further, the embedded wood 21 is placed on the floor beam 5, and the end portion of the surface floor material 4 is placed thereon. In the figure, 24 is a girder member attached to the upper edge of the girder of the stairs 7, 25 is a skirting board, 26 is a gypsum board stretched on the lower surface of the staircase main body 1, and the base rail 27 is the lower surface of the staircase main body 1. The gypsum board 26 is attached to the base rail 27.

FIG. 5 shows another embodiment of the present invention. In this embodiment, there is shown an embodiment in which the Daihiki 28 exists on the floor 2 of the floor 2 shown in FIG.

FIG. 6 shows still another embodiment of the present invention. In this embodiment, there is shown an embodiment in which the frame member 20a of the floor panel 20 exists in the X direction of the floor 2 shown in FIG.

[Effect of the Invention] In the present invention, as described above, the upper part of the staircase main body is attached to the floor part of the upper floor, and the upper step frame separate from the staircase main body is attached on the upper side of the staircase main body and the upper surface of the upper step frame. And the surface of the floor on the upper floor is flush with the top surface of the floor material, so the upper frame can be installed separately from the staircase body while adjusting the mounting position in the vertical direction on the upper side of the staircase body. , Even if the thickness of the surface floor material of the upper floor is different, the upper surface of the surface floor material and the upper surface of the upper frame can be installed flush with each other.
