Lower cap member 11 and lower horizontal beam 44 screwed to upper and lower brackets 48, 49 of 0
It is assembled into a frame unit 42 composed of.

Next, to describe the case of attaching the handrail 40 using the Kasagi 10 configured as described above to the Veeranda 55, first, one handrail unit 41 is attached.
The strut unit 45 of one handrail unit 41 is engaged with the strut unit 46 of the other handrail unit 41 in a snap manner, so that the two handrail units 41 are connected.

Next, the strut units 45, 46 are engaged with the strut units 46, 45 of both handrail units 41 in a snap-like manner, thereby forming struts 47 on both sides of the two handrail units 41 that are connected.

The lower end of the handrail unit 41 connected in this way is screwed to an anchor embedded in the veeranda 55 in advance and fixed to the veeranda 55.

When the two handrail units 41 are fixed to the velander 55 in this way, the lower Kasagi member 11 is connected to the top of the handrail unit 41, so the upper Kasagi member 12 is pressed against the lower Kasagi member 11, and the downward side wall 25 of the handrail unit 41 is pressed against the lower Kasagi member 11. , 26 are engaged with the engaging portions 13, 14 in a snap manner, and at the same time, the ribs 15, 16 are engaged with the upward flanges 20, 21.
The cap 10 is assembled to the top of the handrail unit 41.

Thereafter, the upper cap member 12 is fixed to the lower cap member 11 using a plurality of screws, and the strips 33 are fitted into the lipped grooves 32 to hide the heads of the screws.

Through such a work procedure, the handrail 40 using the cap 10 is installed on the velanda 55.

If the aforementioned lower cap member 11 is formed by bending a metal plate, the engaging portions 13 and 14
can be replaced with cutouts formed on the flange at appropriate intervals in the length direction of the lower cap member 11.

Note that this Kasagi 10 does not use the handrail unit 41, but instead fixes the pillars 47 to the Veranda 55 at appropriate intervals, and attaches the lower Kasagi member 11 having the same length as the upper Kasagi member 12 to the pillar 47, Of course, it is possible to construct the handrail 40 by incorporating a handrail or a panel between the pillars 47 and assembling the upper capping member 12 on the upper surface of the lower capping member 11.
