<Effect of Example>
As described above, both ends of the handrail 7 of the outer corridor 4 of the present embodiment which is the first and second embodiments provided on the upper floor of the building body 1 having a plurality of floors are respectively the building body 1 and the ground. An elongated headboard base 11 supported by one of the columns 5 standing upright, a plurality of panel units 14 having upper ends supported by the headboard base 11, and a pair of panel units 14. The intermediate strut 17 is connected to the headboard base 11 and the lower end is connected to the end of the floor beam 27 extending in the width direction of the outer corridor 4. Acts as a stop. Thereby, since the downward bending of the headboard base 11 can be suppressed, even when the span of the outer corridor 4 is long, sufficient handrail strength can be ensured.

  The handrail in the outer corridor has a handrail base 10 that extends in the length direction and is provided on the side of the floor plate portion 6 of the outer corridor 4, and the lower end portion of the panel unit 14 is supported by the handrail base 10. Thus, the panel unit 14 is sandwiched and held between the headboard base 11 and the handrail base 10, and the intermediate column 17 is connected to the support panel 10 b which is the end of the handrail base 10 in the length direction. The handrail strength including the base 10 can be further ensured.

  In addition, since the panel unit 14 is sandwiched and held between the headboard base 11 and the handrail base 10, the handrail 7 of this embodiment can be configured in a so-called “Kandon” type. . Thereby, since the panel unit 14 can be attached and detached from the corridor side of the handrail 7, the work can be performed safely and the risk of the panel unit 14 falling to the outdoor side can be sufficiently suppressed.

  Further, since the handrail base 10 is connected to the end portion of the floor beam 27 via the eaves beam 22 extending in the length direction of the outer corridor 4, the handrail strength can be further ensured.

  Further, the lower end portion of the intermediate strut 17 has a shape including a substantially flat web portion 17a and flange portions 17b rising from both ends of the web portion 17a, and the end portion of the floor beam 27 is the web portion 17a. Therefore, the connection strength between the intermediate column 17 and the floor beam 27 can be further increased, the handrail strength can be further secured, and the number of columns 5 can be reduced.

  Further, since the lower end portion of the intermediate column 17 is connected to the support panel 10b which is the end portion in the length direction of the handrail base 10 at the flange portion 17b, the connection strength between the handrail base 10 and the intermediate column 17 is strong. The handrail strength can be further ensured.

  Moreover, even when the building 1 shown in the second example has a semi-fireproof structure, the floor board portion 6 is covered with the semi-fire resistant coating materials 34 to 37, and the handrail 7 of the present embodiment is applied to the semi-fire resistant coating material 34. Specifically, a quasi-fireproof structure can be realized simply by fixing the handrail base 10, the intermediate strut 17 and the like. As a result, it is possible to realize a semi-fireproof structure while having the same structure as the general structure as shown in the first embodiment, and it is possible to achieve waterproof reliability and fireproof performance with a simple structure while sharing specifications. Satisfaction can be achieved, and in addition, the handrail strength can be ensured.
