And when installing the other panel unit (for example, panel unit 50 (A)), the fitting protrusion 54b of the vertical hook 54 and the fitting concave groove 55b of the vertical hook 55 were fitted. The panel unit 50 (A) is slid downward along the vertical hook 55.
Therefore, also in this case, the panel unit 50 (A) can use the fitting portion 56 formed by the fitting protrusion 54 b and the fitting groove 55 b as a slide guide, and is excellent in workability.

Moreover, the panel unit 50 forms the ventilation | gas_flowing part 80 which opened the space | interval in the extending direction of the handrail HR between the adjacent panel units 50, and arrange | positions them.
Further, since the lower clamping groove 36 is opened upward at the position of the ventilation portion 80, this portion is covered with the eye plate 81 (see FIG. 4).

Next, the upper frame 40 is attached.
In this case, first, the headboard base 41 is fixed to the reinforcing member 21 of the support column 20 and the upper collar 51b of the panel unit 50.
In fixing the headboard base 41 and the reinforcing member 21, reinforcement is made in a hole (not shown, formed along the outer periphery of the reinforcing member 21 in FIG. 11) formed in the base portion 41 a of the headboard base 41. The fixing piece 21c of the material 21 is inserted, and the fixing piece 21c protrudes from the base portion 41a (see 10).

  Then, as shown in FIGS. 9 and 10, the base side fixing piece 43a of the fixing bracket 43 is fixed to the base portion 41a of the coping base 41 with screws 43c, and the reinforcing material side fixing piece 43b of the fixing bracket 43 is fixed. A bolt 43d and a nut 43e are fastened and fixed to the fixing piece 21c of the reinforcing member 21.

For this reason, when the handrail HR is viewed from the outside of the building, it is hidden by the vertical gutter 51a and does not appear in the appearance. Therefore, the appearance is clear and the design can be improved as compared with the structure in which the support column 20 appears in the appearance.

In addition, the strut 20 is formed in a shape that suppresses the width in the extending direction of the handrail HR so as to be hidden by the vertical rod 51a. However, by providing the belt-shaped reinforcing material 21, rigidity can be ensured.
Furthermore, the reinforcing material 21 has a band shape, and in particular, the rigidity in the inside and outside direction of the building can be secured. In addition, the upper end of the reinforcing member 21 is firmly fixed via the headboard base 41 and the fixing bracket 43 of the upper frame 40, and the lower end is fixed to the support frame 60 by the fixing portion 21a. High rigidity in the extending direction of the handrail HR can be obtained.

  Further, the panel unit 50 can ensure the rigidity of the handrail HR in the vertical direction and the extending direction. That is, the panel unit 50 includes a fitting portion 90 that engages the column decoration material 22 of the column 20 with the vertical frame 51a. Since the vertical frame 51a is supported by the lower frame 30 and the upper frame 40, Directional rigidity can be ensured. Furthermore, since the vertical rod 51a constitutes the quadruple frame-shaped rod frame body 51, it is possible to further obtain high rigidity in the extending direction of the handrail HR.

  In the panel unit 50 (B), the vertical rod 55 is fitted to the vertical rod 54 of the panel unit 50 (A) via the fitting portion 56, and the end portion on the opposite side to the vertical rod 55 is further provided. The vertical rod 51a is engaged with the support member 22 of the support 20 via the fitting portion 90 shown in FIG. For this reason, the rigidity of the handrail HR can be further improved.

  In addition, since the ventilation part 80 is set between the panel units 50, the air permeability of the balcony BL can be ensured.
