The present invention relates to a support structure for the pillar.

[Technology background]

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 6, 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. 7, 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. 8 (see Japanese Utility Model Publication No. 59-27458).

This has a substantially U-shaped cross section, and both side wall portions 5a,
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 assembled in this way are assembled by stacking the flange portions 6b, 6b of the connecting hardware 6 and the flange portions 5b, 5b of the mounting hardware 5 vertically. bolt 11,
11, it is fixed to the parapet P by fixing it with nuts 12, 12. The handrail support post 2 is thus erected and fixed at the top of the parapet P. In addition, 13 in Fig. 6 is the parapet P.
The mortar 14 is caulking material applied to the side wall of the building.

[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 connecting hardware 6 and the support column 2 in advance, but also requires several types of mounting hardware 5 whose width corresponds 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 for this is to arrange a pillar support consisting of a board having a hole through which the fixing member is inserted and a support rod erected on the top surface of this board at the top of the parapet, An L-shaped holding member with a long hole drilled in the width direction of the parapet corresponding to the part is superimposed on the substrate, and the side surface of the holding member is fixed to the side wall of the parapet, and a fixing member is inserted into the long hole and the hole. At the same time, the support rod is passed through the hole provided in the cap to cover the parapet with the support rod, and a handrail is attached to the support rod. This is achieved by a support structure for a handrail support column that is erected by inserting the lower end of the handrail support column.

The lower end of the column 20 is inserted into the support rod 21 protruding from the hole 25 of the column 24 to support it.

That is, the board 22 is connected to the anchor bolt 2.
6, 26, etc., is a channel-shaped metal plate as shown in Fig. 4, and anchor bolts 26 are installed at both ends along the longitudinal direction of the parapet P. , 26 are bored therein, and a support rod 21 for supporting the support column 20 is erected and fixed in advance by means such as welding at the center of the upper surface thereof. A pillar support H is formed. Support rod 2 fixed to this substrate 22 in advance
Reference numeral 1 has a square-shaped cross section and is formed in a size that can be inserted into the support column 20.

On the other hand, a presser member 23 that presses the upper surface of the board 22
is fixed to the parapet side wall surface Pb by an anchor bolt 28 or the like, and is bent into an L-shape, and an anchor bolt 28 is attached to the side portion 23a of the parapet side wall Pb as shown in FIG. Bolt insertion holes 23c, 23c are drilled for the bolts to pass through, and on the other hand, the upper part of the parapet that protrudes to the top Pa has protrusions 23b for holding down the board 22 at two locations in the longitudinal direction of the parapet P with the support rod 21 in between. This protrusion 23b is provided with a long hole 23d corresponding to the bolt insertion hole 22a of the board 22. This long hole 23d is designed to accommodate the width of the parapet top Pa.
It is formed in the width direction of Pa.

In addition, Kasagi 2 is crowned by the top of the parapet Pa.
