Generally, a parapet is erected at the end of the roof of a building, and especially when the height of the parapet is low, a handrail is provided for safety reasons. In the past, as shown in Figure 4, this handrail 1 was installed separately inside the parapet P, but in recent years, in order to improve work efficiency and secure rooftop space, As shown in FIG. 5, the handrail 1 is provided on the upper part of the cap 3 attached to the parapet P. However, since the cap 3 is made of a plate material such as aluminum, if the support post 2 of the handrail 1 is directly attached to the cap board 3, its support is weak, and therefore various handrail supports are used to firmly fix the post 2. A support structure has been devised.

[Conventional technology]

Conventionally, there has been a support structure for such a handrail column as shown in FIG. 6 (see Japanese Utility Model Publication No. 59-27458).

Flange portions 5b, 5 protruding outward at the lower end of 5a
A mounting metal fitting 5 having a shape b formed thereon, and a connecting metal fitting 6 having a substantially U-shaped cross section and having flanges 6b, 6b formed at the lower ends of both side wall portions 6a, 6a projecting inward are used. The mounting hardware 5 has its horizontal part 5
An anchor 7 is welded to the lower surface of the parapet P, and when the parapet P is constructed, the anchor 7 is buried in the parapet P, thereby being fixed to the top end of the parapet P. In addition, the upper end of the handrail support post 2 is placed on the bottom surface of the handrail 1 and fastened with screws 8, while
A cap 3 is attached to the lower end of the handrail support post 2, and the connecting hardware 6 is brought into contact with the bottom surface of the horizontal portion 3a of the cap 3, and the screws 9 passing through the connecting hardware 6 and the cap 3 and the handrail 1 are connected to each other. The support 2 is fixed to the cap 3 by a connecting bolt 10 that connects the connecting hardware 6. The pillar 2, the cap 3, and the connecting hardware 6 are assembled in this way into one piece by vertically overlapping the flange portions 6b, 6b of the connecting hardware 6 and the flange portions 5b, 5b of the mounting hardware 5. Bolt 11,1
1. It is fixed to the parapet P by fixing the nuts 12, 12. The handrail support post 2 is thus erected and fixed at the top of the parapet P. In FIG. 6, 13 is mortar applied to the side wall of the parapet P, and 14 is caulking material.

[Problem that the invention attempts to solve]

However, in the above-mentioned conventional handrail support structure, since the handrail support 2 is integrated with the cap 3 and the connecting hardware 6, there are various Kasagi 3
In addition, it is not only necessary to assemble the support 2 to the connection hardware 6 in advance, but also requires several types of mounting hardware 5 whose widths correspond to the width of the top of the parapet P. There is a problem in that many parts must be prepared for installation. In addition, Kasagi 3 and connection hardware 6
Since the and support column 2 are integrated, there is a problem that the capacity becomes bulky during transportation, which increases the transportation cost.

[Means for solving problems]

The present invention has been made in view of the above circumstances, and provides a support structure for handrail columns that can be erected using the same member on parapets of any width and that can reduce transportation costs. The means is to fix a board having a support rod erected on the top surface to the top end of the parapet, and to press the top surface of the board with a pair of L-shaped press members fixed to the side walls of the parapet. A handrail post characterized in that the support rod is passed through a hole provided in the cap and the parapet is covered with the support rod, and the lower end of the handrail support is inserted into the support rod and erected. This is done by supporting structure.
