Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an outer wall used for a staircase of a multi-story row house having individual dwelling units on the first and second floors.

[0002]

2. Description of the Related Art Conventionally, the outer wall of this type of staircase 9 is shown in FIG.
It was constructed as shown in. A floor beam 2 is erected on the upper end of the outer wall panel 1 on the first floor, and a mounting portion 4 at the bottom of the floor beam 2 is attached to a mounting hardware 3 attached to the upper end of the outer wall panel 1 on the first floor.
Is fitted and attached, the lower end of the handrail panel 5 on the second floor is placed and fixed on the floor beam 2, and the end of the floor panel 6 on the second floor is placed and fixed on the floor beam 2 to form the handrail panel 5. Exterior wall panel 1
The curtain plate 7 is arranged so as to cover the space between the space and the curtain plate 7, and the curtain plate 7 is attached to the outer surface of the floor beam 2.

[0003]

However, in the above-mentioned conventional example, since the floor beam 2 erected on the outer wall panel 1 on the first floor is arranged right above the outer wall panel 1, the handrail is provided. The panel 5 is mounted with its lower end placed on the floor beam 2, and a curtain plate 7 must be mounted to cover between the lower end of the handrail panel 5 and the upper end of the outer wall panel 1. There is a problem that the workability is poor because a member such as the plate 7 is required and the curtain plate 7 is attached.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a structure of an outer wall of a staircase that can improve workability without requiring a curtain plate.

[0005]

In order to achieve the above object, the structure of the outer wall of the staircase according to the present invention is such that the floor beam 2 is installed on the upper end of the outer wall panel 1 on the first floor and the floor beam 2 is installed on the first floor. The outer wall panel 1 is displaced toward the indoor side, and the handrail panel 5 on the second floor is arranged on the outer wall panel 1 on the first floor so that the outer surface of the handrail panel 5 and the outer wall panel 1 on the first floor are flush with each other. Fix the inner surface of the lower part of the handrail panel 5 over the outer surface of the floor beam 2,
It is characterized in that the end portion of the floor panel 6 on the second floor is mounted and fixed on the floor beam 2.

[0006]

According to the above construction, even if the outer surface of the outer wall panel 1 and the outer surface of the handrail panel 5 are flush with each other, the floor beam 2
The lower end of the handrail panel 5 can be positioned on the outer wall panel 1 without hindering the installation, the curtain plate 7 need not be attached unlike the conventional case, and the number of members can be reduced and the workability is improved. it can.
