Description

[Detailed description of the invention] This invention relates to a fitting for connecting the rim to the support of fences that use a rim and vertical bars for the support, such as fences along sloped and complicatedly curved roads. It is.

In the case of a fence installed on non-flat, non-straight ground, as shown in an example in Fig. 1, the pillars 1 can be installed vertically, but the fences 2A and 2B are inclined along the terrain, and the pillars 1 The adjacent furring edges 2A with
2B are oriented at an acute or obtuse angle with each other.

That is, this type of fence requires a furring connecting fitting that can connect the furring to the support in any direction.

As a coupling fitting that meets this requirement, there is a coupling fitting proposed in Japanese Utility Model Publication No. 57-47321, but the coupling fitting described in this publication uses a cap-shaped member that fits on the support as a core. It has a structure in which a cylindrical member, into which the end of the furring material is fitted, is connected to a ring-shaped member fitted therein by horizontal bolts.

In other words, it has a structure in which there is a core member, a ring-shaped member is fitted into it in advance, and a cylindrical member is attached to the ring-shaped member with bolts and nuts, so it requires considerable skill to assemble. Not only does it require skill, but it also requires a lot of time and is inefficient.

The purpose of this invention is to provide a rim coupling fitting for a column that eliminates the difficulties of the coupling fittings described in the above publication, and does not include a core member and can be assembled from the side to the column. It is characterized by being made up of two members that can be assembled by enclosing the strut and the rim from the sides.

Next, the coupling fitting of this invention will be explained by way of examples with reference to the drawings.

Fig. 2 shows an embodiment of the coupling fitting of this invention in an assembled state in a front view, Fig. 3 shows a plan view, Fig. 4 shows a bottom view, and Fig. 5 shows a left side view. 6 is a right side view, and FIG. 7 is a front view. As shown in the drawings, the coupling fitting of this invention is provided with a male engagement part 4 at one end of an arcuate curved part 3 whose inner surface can come into contact with a portion of about 120° to 130° of the circumferential surface of the support column 1, A connecting piece A has a vertical bar fixing part 5 at the other end, and a female engaging part 6 that can be freely engaged with the male engaging part 4 at one end.
and a connecting piece B having an arcuate curved portion 3 whose inner surface abuts at a symmetrical position on the circumferential surface of the support column 1 that is abutted. In FIG. 2, reference numeral 12 indicates a vertical member.

FIG. 8 is a partially cutaway plan view of the connecting piece A, FIG. 9 is a partially cutaway plan view of the connecting piece B, and FIG.
The figure shows the coupling piece A in a left side view, and FIG. 11 shows the coupling piece B in a left side view.

The coupling piece B has a vertical bar fixing part 5 that faces the vertical bar fixing part 5 of the coupling piece A and is parallel to the vertical bar fixing part 5 when attached to the column 1.

The vertical beam fixing part 5 has horizontal through holes 7A and 7 at two positions, upper and lower.
A furrow clamping piece 8 curved into an arc is rotatably attached to the outside of each vertical frame fixing part 5 by a shaft 9 fixed in the upper transverse through hole 7A.

The body edge holding piece 8 has a structure in which two pieces attached to the connecting pieces A and B touch each other at the upper part.

Furthermore, a bolt through hole 10 is formed in the furring edge holding piece 8 to match a horizontal through hole (not shown) provided in either of the furring edges 2A, 2B.

As shown in FIG. 2, the first
The coupling fittings are shown in a plan view in Figure 2, a front view in Figure 13, a left side view in Figure 14, a right side view in Figure 15, and a partially cutaway bottom view in Figure 16. be.

The connecting metal fitting is a connecting metal fitting used at the top of the support column, and consists of a connecting piece A' corresponding to the connecting piece A of the connecting metal fitting, and a connecting piece B' corresponding to the connecting piece B of the connecting metal fitting.

As shown in FIG. 17 in a partially cutaway bottom view, and as shown in FIG. A vertical bar fixing part 5 is provided on the vertical bar fixing part 5, and a shaft 9 is fixed to the upper part 7B' of the horizontal through holes 7A' and 7B' provided in the vertical bar fixing part 5. It is similar to the connecting piece A in that it supports the .

On the other hand, as shown in FIG. 19 as a partially cutaway sectional view and as shown in FIG. A hooking part 6 is provided, and a vertical bar fixing part 5 is provided at the other end, and a shaft 9 fixed to the upper part 7B' of the horizontal through holes 7A' and 7B' of the vertical bar fixing part 5 holds the furring clamping piece 8. is supported.

The difference between the connecting piece B' and the connecting piece B is that on the top,
A convexly curved top plate 11 is fixed to the upper end of the support 1.

The bolt passage holes in the coupling fittings are square holes, but this is because a bolt 14 having a prismatic detent stopper 13 on its head is used, as shown in Figures 21a and b. be. The bolt through hole may be a round hole when a normal bolt is used.

The coupling fitting of this invention having the above-mentioned configuration,
is attached to a post 1 erected at a predetermined location with the connecting metal fittings on top and the connecting metal fittings on the bottom.

To attach the coupling fittings to the pillar, connect the male hooking portions 4 of the coupling pieces A and A′ to the coupling pieces B,
While making the male and female fit into each of the female engaging portions 6 of B',
Attach from the side of post 1.

Connecting pieces A and B holding support column 1, and A' and
B' is one of the horizontal through holes 7A and 7B of the vertical beam fixing part 5.
Bolt 7B for the coupling fitting, 7A' for the coupling fitting (both located on the lower end side),
When fixed using nuts (not shown), tightening the bolts and nuts tightens the column and prevents it from falling.

In particular, since the top plate 11 fixed to the connecting piece B' of the connecting fitting is completely separated from the connecting piece A',
When the bolts and nuts are tightened, the connecting piece A' is easily tightened. For this reason, the support column 1 can be strongly tightened.

On the other hand, by inserting the end of the furrow 2A between the furrow holding pieces 8, 8, passing a bolt through the bolt passage hole 10, and tightening the nut, the furrow 2A is fixed.

As for the lower furring 2B, two coupling fittings may be used.

In the case of the fence end, one each of the coupling fittings and are used.

For horizontal bending of the fence,
When attaching the coupling fitting to the support column 1, the position may be adjusted in the horizontal direction, and in order to accommodate the inclination, the direction of the furring clamping piece 8 may be determined vertically with respect to the shaft 9.

As is clear from the above explanation, the coupling fitting of this invention can extremely easily fix the rim and vertical beam to the column, and in particular, it can be attached to the column from the side, making it easy to attach and detach. It has excellent advantages such as being extremely easy, greatly reducing the time required for fence construction, and allowing even inexperienced workers to assemble the fence with high efficiency and accuracy.
