INDUSTRIAL APPLICABILITY The present invention can form an outdoor stair landing by providing a floor material on a cantilever projecting from the main body of the house, eliminating the need for a pillar for supporting the landing.
The present invention relates to a landing structure of stairs that can enhance the appearance and streamline the construction of the landing.

[0002]

2. Description of the Related Art A multi-storey house is sometimes provided with outdoor stairs extending in a straight line along the house.
Conventionally, the landing b of the outdoor stairs a has been supported by columns c rising from the ground, as schematically shown in FIG.

[0003]

However, in such a conventional one, since the column c is used, the cost is increased, and the column c is exposed to the outside, so that the design is deteriorated and the appearance is reduced. In addition to causing damage, finishing the landing b at the joint where the pillars c and the landing b are joined requires some effort, which may result in poor construction efficiency.

According to the present invention, the floor material for forming the landing is provided on the pillar arranged on the main body of the house or the cantilever projecting outward from the beam, and the pillar for supporting the landing is unnecessary. The purpose is to provide a landing structure of stairs that can improve design and appearance and reduce costs.

SUMMARY OF THE INVENTION The present invention is a stairway landing structure for forming a landing of outdoor stairs extending linearly along a main body of a house, the structure being a pillar or a beam member arranged outside the main body of the house. A horizontal cantilever is projected on one side, and a floor material for landing formation is provided on the cantilever.

[0006]

[Function] A cantilever is projected outward from a pillar or beam placed on the main body of a house, and a floor for forming a landing is provided on the cantilever. In this way, since the landing of the outdoor stairs is supported by the cantilever, it is possible to reduce costs, improve design, and enhance the appearance, without the need for supporting columns as in the past.

Further, since the support pillars are eliminated, it is possible to eliminate the labor required for attaching the finishing member at the joint between the support pillars and the landing, so that the finishing work of the landing can be made efficient.

The house main body is, for example, a three-story building, and the cantilever 3 projects from the beam member 2 supporting the floor of each floor of the house main body in this embodiment.

As shown in FIG. 3, the beam member 2 is made of an I-shaped steel in which vertical flanges are provided on the upper and lower sides of a vertical web in this example, and the beam member 2 extends along the outer wall between columns of a main body of a house (not shown). The floors of each floor can be supported by being horizontally laid.

In addition, a rectangular mounting piece 10 projecting outward beyond the upper and lower flanges is fixed to the groove portion of the beam 2 facing outward by bolting, welding or the like.
The inner end of the cantilever 3 is bolted to zero.

The cantilever 3 is formed from an I-shaped steel in which horizontal flanges 3B and 3C are provided above and below a vertical web 3A, and the inner end of the web 3A is bolted to the mounting piece 10 so that each floor is fixed. The beam members 2 and 2 are horizontally displaced from each other, and two of the beam members 2 are projected outward at right angles to the beam members 2 and horizontally. It should be noted that the cantilever 3 may be provided so as to project outward from the pillar arranged on the main body of the house.

A curtain plate 11 is laid between the outer ends of the parallel cantilevers 3 and 3 on each floor. The curtain plate 11 is made of a steel material having a U-shaped cross section in which horizontal projecting pieces 13 and 13 are projected outward from above and below a vertical standing piece 12, and a vertical plate which projects inwardly from the vicinity of both ends of the standing piece 12. By fixing the fixing pieces 14, 14 along the facing surfaces of the webs 3A, 3A of the cantilever beams 3, 3 and bolting them, the groove portions are directed outward so that the outer ends of the cantilever beams 3, 3 become horizontal. Erected.

The curtain plate 1 attached to the cantilever beams 3 and 3 protruding from the beam member 2 below the floor, that is, the beam member 2 supporting the second floor.
As shown in FIG. 2, both ends of 1 are substantially aligned with the side edges of the cantilever beams 3 and 3 opposite to each other, and also support the beam member 2 on the upper floor, that is, the beam member supporting the third floor. One end edge of the curtain plate 11 attached to the cantilever 3 projecting from 2 further away from the cantilever 3 below is cut off at substantially the center of the cantilever 3.
Further, on the cantilever 3 on this floor, a curtain plate 15 for covering the cantilever 3 by covering the side edge of the cantilever 3 is provided with fittings 16, 16 bolted to the web 3A. Mounted using.

Further, a floor material 4 is arranged on the cantilever beams 3 and 3 on each floor. The floor member 4 is a pair of base plates 17, 17 attached to the upper surfaces of the cantilevers 3 and 3 and having a horizontally long rectangular shape extending outward.
And a plurality of joint members 19 formed of a cross-section U-shaped member having a groove portion facing downward, and a plurality of joint members 19 ...
