The protrusion length (P) of the first stopper part (315), the second stopper part (325), the third stopper part (335), and the fourth stopper part (345) is equal to the thickness of each outer flange.

Therefore, the inner surface of each of the first stopper part (315), the second stopper part (325), the third stopper part (335), and the fourth stopper part (345) and the inner surface of each outer flange form a continuous plane, thereby minimizing friction or interference when inserting the lower frame (110) or the upper frame (120).

In this embodiment, the cap (300) is further provided with a cap engaging portion that forms a mutual engagement with the outer flange (260).

In this embodiment, the cap catch portion includes a first cap catch portion (370) protruding from the inner surface (311) of the first cap body (310) toward the second cap body (320), and a second cap catch portion (380) protruding from the inner surface (321) of the second cap body (320) toward the first cap body (310).

The above outer flange (260) further includes a first catch hole (271) formed to penetrate the first outer flange (261) and a second catch hole (272) formed to penetrate the second outer flange (262).

The first cap catch portion (370) is inserted into the first catch hole (271) to form a mutual catch, and the second cap catch portion (380) is inserted into the second catch hole (272) to form a mutual catch.

To facilitate assembly of the first cap body (310) and the first outer flange (261), an inclined surface is formed on the first cap engaging portion (370).

The first cap-catching portion (370) includes a first cap-slanted surface (371) that protrudes obliquely in the insertion direction of the first outer flange (261), and a first catch end (372) that is formed to be bent from the insertion direction end of the first cap-slanted surface (371) to the inner surface (311) of the first cap body (310).

The above first cap slope (371) is formed to protrude toward the second cap body (320) as it increases in the insertion direction of the outer flange (260), thereby preventing mutual interference when inserting the first outer flange (261).

The above first catch (372) is inserted into the above first catch hole (271) to form a mutual catch in the opposite direction of insertion of the outer flange (260).

The second cap-catching portion (380) includes a second cap-slanted surface (not shown) that protrudes obliquely in the insertion direction of the second outer flange (262), and a second catch end (not shown) that is formed to be bent from the insertion direction end of the second cap-slanted surface to the inner surface (321) of the second cap body (320).

Since the first cap-catching portion (370) and the second cap-catching portion (380) are formed in a symmetrical shape, a detailed description thereof is omitted.

Through the above-described structure, the cap (300) and the outer flange (260) can be easily assembled. Since the cap (300) is arranged to surround the outer flange (260) and is in close contact with the column, the column hole (15) can be sealed more effectively, and rainwater can be effectively prevented from penetrating into the interior of the first vertical column (10) or the second vertical column (20).

The remaining configuration is similar to the second embodiment above, so a detailed description is omitted.
