Description

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

[Prior Art] Conventionally, when attaching the upper part of the stairs to the floor side of the upper floor, a wooden grab for receiving the stairs is attached as a floor constituent member of the upper floor, and the wooden grab of the stairs is attached to the wooden grab. The structure was such that the upper end was put on and attached.

[Problems to be Solved by the Invention] However, in the conventional example as described above, when mounting the stairs, the upper end of the girder is placed on the wooden haul and the stairs are mounted. Positioning is troublesome, and since the upper end of the stairs is simply placed on the stairs until the main fixing, the positioning is even more troublesome. You must hold it by hand and fix it firmly so that it does not
The work was complicated.

The present invention has been devised in view of the above-mentioned problems of the conventional example, and an object thereof is to provide a staircase mounting structure capable of easily and accurately mounting staircases.

[Means for Solving the Problem] In the staircase mounting structure of the present invention, the staircase receiving piece 2 is projected forward from the fixed portion 1, and the hook piece 3 is projected upward from the tip of the staircase receiving piece 2 to make the metal. Of the stairs receiving beam 4, the fixing portion 1 of the stairs receiving beam 4 is fixed to the floor constituent member 5 on the upper floor by the fixing means 6, and the cross member 9 is installed between the opposing girders 8 at the upper part of the stairs 7. Is placed on the stair receiving piece 2 of the stair receiving beam 4 and the hooked portion 3 of the horizontal member 9 is hooked on the hooking piece 3, and the horizontal member 9 is fixed to the floor component 5 to the stair receiving beam 4 by the fixing means 11. The present invention achieves the object of the present invention by solving the problems of the conventional example described above by adopting such a configuration.

[Operation] Then, the staircase receiving beam 4 made of metal is fixed to the floor constituent members 5 such as the floor panel 12, the floor beam 13 and the Daihiki 14 on the upper floor, and the stairway receiving beam 4 is used. An upper part of the stairs 7 is accurately fixed by placing a horizontal member 9 which is erected between the opposing girders 8 on the upper part of the stairs 7 on the piece 2 and by hooking a hooked portion 10 of the horizontal member 9 on the hooking piece 3. It can be temporarily positioned and can be temporarily supported, and in this state, it is permanently fixed by the fixing means 11, and after the main fixing portion, the attachment state is surely supported by the support by the fixing means 11 and the support by the stair receiving beam 4. It was made possible.

[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 a floor beam 13 is present as the X-shaped floor constituting member 5 of FIG.
The floor beam 13 is made of H steel, and the fixing portion 1 of the stair receiving beam 4 is fixed to the upper flange 13a of the floor beam 13 by fixing means 6 such as bolts. The staircase receiving beam 4 made of metal is formed by projecting a staircase receiving piece 2 forward from the fixed portion 1, and projecting a hooking piece 3 upward at the tip of the staircase receiving piece 2.
In the embodiment shown in FIG. 2, the fixed portion 1 of the stair receiving beam 4 is fixed to the upper vertical piece 1a and the vertical piece 1b at right angles to the upper horizontal piece 1a, the vertical piece 1b, the upper horizontal piece 1a and the vertical piece 1b. The upper lateral piece 1a of the fixing portion 1 is fixed to the upper flange 13a of the stair receiving beam 4 by the fixing means 6. On the upper part of the stairs 7, a horizontal member 9 is installed between the opposing girders 8. In the figure, reference numeral 15 denotes a tread plate, and this tread plate 15 is also installed between the opposing girders 8. Then, in order to attach the upper part of the stairs 7 to the floor portion of the second floor, the horizontal bridge member 9 installed between the opposing girders 8 on the upper part of the stairs 7 is placed on the staircase receiving piece 2 of the stairway receiving beam 4 and the hooking pieces are also attached. The hooked portion 10 at the lower portion of the rear portion of the horizontal member 9 is hooked on the floor 3, and the floor component 5 is fixed by the fixing means 11 such as a screw tool or a bolt while the stair 7 is positioned and supported by the stair receiving beam 4 in this manner. The horizontal member 9 is fixed to the stair receiving beam 4.
In the accompanying drawings, reference numeral 22 is a step board, 16 is an ascending frame arranged above the horizontal member 9, and 17 is a dust rail provided on the upper portion of the girder 8.
Further, 12 is a floor panel, and a floor material 18 stretched on the surface of the floor panel 12 and a rising frame 16 are flush with each other. Then, in the embodiment shown in FIG.
It supports 18 edges. Further, reference numeral 20 in the drawing denotes a gypsum board stretched on the lower surface of the stairs 7, a base rail 21 is attached to the lower surface of the stairs 7, and the gypsum board 20 is attached to the base rail 21.

FIG. 3 shows another embodiment of the present invention. In this embodiment, there is shown an embodiment in the case where a large drawing 14 is present as the floor constituting member 5 of X ways in FIG. This big pull 14
Is wood, and the staircase receiving beam 4 is fixed to the front surface by fixing means 6 such as a screw tool or a bolt. In this embodiment, the vertical piece 1b which is the fixing portion 1 is integrally fixed to the floor panel 12 together with the haul 14 by the bolt which is the fixing means 6, and the vertical piece 1b is further fixed by the screw tool which is the fixing means 6. It is firmly attached to Daihiki 14.

FIG. 4 shows still another embodiment of the present invention. In this embodiment, there is shown an embodiment in which the frame member 12a of the floor panel 12 is present as the X-shaped floor constituting member 5 in FIG. In this embodiment, the vertical piece 1b which is the fixing portion 1 is fixed to the frame member 12a of the floor panel 12 by the fixing means 6 such as bolts and screws.

[Effects of the Invention] According to the present invention, as described above, the staircase receiving beam is projected forward from the fixing portion and the hooking piece is projected upward at the tip of the stairway receiving piece to form a metal stairway receiving beam. , Fixing the fixing part of the stair receiving beam to the floor constituent member on the upper floor by fixing means,
Place the horizontal bridge installed between the opposite girders on the top of the stairs on the step receiving piece of the stair receiving beam, and hang the hooked part of the horizontal frame on the hooking piece, and place it horizontally on the floor component or the stair receiving beam. Since the bridge material is fixed by the fixing means, it is possible to place the horizontal bridge material installed between the opposite girders of the upper part of the stairs on the stairs receiving piece and hook the hooked part of the horizontal bridge material on the hooking piece. It can temporarily support the upper part of the stairs by positioning it at an accurate position.
When attaching the stairs, it is possible to easily and permanently fix the stairs in a state in which the stairs are temporarily supported by the fixing means at a precise position, and in particular, it is possible to prevent the stairs from being displaced until the stairs are permanently fixed due to the presence of the hooking piece. Moreover, after the main fixing, the mounting state can be surely supported by the support by the fixing of the fixing means and the support by the stair receiving beam.
