Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an auxiliary column fixing device for fixing the upper end of an auxiliary column to the column via a connecting fitting.

[Prior Art and Problems to be Solved] Conventionally, when reinforcing the pillars of fences, etc. with auxiliary pillars, a U-shaped connecting metal fitting made of a single member was fitted to the pillar and the front part of the support was reinforced. The auxiliary column was fixed to the column by holding the column and fixing the upper end of the auxiliary column to the rear part of the connecting fitting using a through bolt.

However, in the conventional structure in which the auxiliary column is fixed to the column via the connecting metal fittings as described above, the U-shaped connecting metal fittings are simply fitted to the pillars, so the connecting metal fittings cannot securely hold the auxiliary pillars. However, the problem was that the support column and the auxiliary column could not be firmly connected.

[Means for Solving Problems] The present invention which solves the above-mentioned conventional problems is an auxiliary column fixing device that fixes the upper end of an auxiliary column to a column via a connecting fitting. The front piece, which is a horizontal piece, and the side piece, which is a vertical piece, form a pair of connecting metal fittings having a substantially L-shaped cross section, and these connecting metal fittings are combined in a facing manner to form a support column and an auxiliary piece. It is attached to the pillar, and the front part of the pair of connecting fittings and the front part of the side piece hold the pillar from both sides, and the rear part of the pair of connecting metal fittings that corresponds to the rear part of the side piece pinches and penetrates the auxiliary pillar. The connecting fitting is fastened with bolts, and the connecting fitting has a bent part at the tip of the front piece, and fits the front side of the support column with the front piece and part of the side piece. It has a locking part that locks to the rear side of the support column approximately in the middle of the piece, and the rear side corresponding to the rear side of the side piece of the connecting metal fitting is formed with a slight slope so as to open outward. Becoming is characterized by becoming.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

Fig. 1 is a side sectional view of an auxiliary post fixed to a post by an auxiliary post fixing device according to an embodiment of the present invention, Fig. 2 is a cross-sectional view of Fig. 1, and Fig. 3 is an embodiment of the present invention. FIG. 4 is a perspective view of the auxiliary column fixing device according to the example, and a plan view of a connecting fitting that constitutes the auxiliary column fixing device.

In the figure, 1 is the pillar of the fence, 2 is the pillar 1
The auxiliary column 10 is an auxiliary column fixing device of this embodiment that fixes the upper end of the auxiliary column 2 to the column 1. A fence consisting of horizontal bars 3 and vertical bars 4 is supported on the pillar 1 as shown in the figure. Further, the above-mentioned pillar 1 and auxiliary pillar 2 are each erected with the upper end of the auxiliary pillar 2 inclined toward the pillar 1 side by embedding its lower end in the installation location 6.

The auxiliary column fixing device 10 of this embodiment includes a front piece 12 as a horizontal piece and a side piece 13 as a vertical piece to form a pair of connecting fittings 11, 11 having a substantially L-shaped cross section.
The connecting fittings 11 are combined in a facing manner and attached to the support column 1 and the auxiliary support column 2, and the above-mentioned support column 1 is connected to both sides by the front portion corresponding to the front part of the front piece 12 and the side piece 13 of the pair of connecting fittings 11. The auxiliary column 2 is held between the rear portions of the side pieces 13 and fastened with through bolts 15.

The connecting fittings 11, 11 are formed into a substantially L-shape by a front piece 12 that fits into the front side of the column 1, and a side piece 13 that sandwiches the side surfaces of the column 1 and the auxiliary column 2.
As shown in the figure, the front piece 12 is formed to have a width that is approximately half the width of the side piece 13, and its tip 12a is bent rearward at approximately a right angle. The front piece 12 fits into the front side of the support column 1 with its tip 12a as shown in the figure. Note that the front piece 12 is replaced by the side piece 1.
By making the width approximately half of that of 3, the connecting fittings 11 and 1 can be connected with the front pieces 12 overlapped as shown in the figure.
1 can be made to face each other.

The side pieces 13 of the connecting fittings 11, 11 have a length that can sandwich the sides of the support column 1 and the auxiliary column 2, and protrude inwardly at a position corresponding to the rear side of the support column 1. A locking portion 13a that locks on the rear side is formed. Also, among the side pieces 13, the auxiliary support 2
A hole 13b for passing the through bolt 15 is provided in the rear portion located on the side surface. Note that a through hole 2a for passing the through bolt 15 therethrough is provided at a position corresponding to the hole 13b on the side surface of the auxiliary column 2.

Next, the connecting fittings 11, 11 are connected slightly so that the rear side of the side piece 13 opens laterally from the side surface of the column 1 when the front piece 12 is fitted to the front side of the column 1 as shown in FIG. It is formed at an angle. That is, the angle formed by the front piece 12 and the side piece 13 is slightly wider than the corner angle (right angle) of the support column 1. When the angle between the front piece 12 and the side piece 13 is equal to the corner angle of the support 1, the tip 12a of the front piece 12 and the locking part 13a of the side piece 13 become an obstacle, making it difficult to connect the connecting fitting 11 from the side of the support 1. Although it cannot be attached, if the side piece 13 is opened laterally as described above, the distance between the tip portion 12a and the locking portion 13a is widened, and the connecting fitting 11 can be easily attached from the side of the column 1.

When fixing the auxiliary column 2 to the column 1 using the auxiliary column fixing device 10 configured as described above,
First, attach the front piece 12 of the connecting fittings 11, 11 to the support 1.
By fitting on the front side of the connecting fittings 11, 11
are positioned opposite to each other on both sides of the pillar 1. Next, the through bolts 15 are passed through the holes 13b and the through holes 2a, and the pieces 13 on both sides of the auxiliary support 2 are fastened together.
By tightening the through bolt 15, the side pieces 13, 13, which are located laterally open, are pressed against the side surfaces of the support column 1 and the auxiliary support column 2. And this side piece 13,
As the front piece 13 is pressed, the front piece 12 is firmly held on the front side of the column 1, and the locking portion 13a of the side piece 13 is locked to the rear part of the column 1, so that a tightening action is exerted on the column 1 and the connecting fitting 11, 11 securely hold the column 1.

Regarding the shape of the connecting fittings 11, 11,
For example, the front piece 12 is not limited to that of the above embodiment.
The dimensions of the side pieces 13 and the like can be arbitrarily determined.

[Effects of the invention] As explained above, according to the invention, the front piece fits into the front side of the column and the side piece has a locking part that locks on the rear side of the column. Since the support column is held from both sides by a pair of connecting fittings formed at an angle, and the auxiliary support column is sandwiched and fastened with a through bolt, the front piece of the connection member is firmly held and locked in front of the support column. When the part is locked to the rear side of the support column, a tightening action is exerted and the effect of reliably holding the support support is achieved.

Further, since the side pieces of the connecting fitting are formed to open laterally, there is an effect that the connecting fitting can be easily attached to the support.
