In the above-mentioned conventional fence, the appearance of the connecting portion between the column 1 and the beam pipe 3 is not necessarily aesthetically good because the bracket 2 and the bolt 5 are exposed and conspicuous. The work of connecting the beam pipes 3 to the columns 1 is performed by bolting each beam pipe 3,
When the number of the beam pipes 3 increases, it is complicated, and it is desirable that the number of the beam pipes 3 can be further simplified.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a fence which is aesthetically pleasing without exposing brackets and bolts for connecting a support and a beam and which is easy to assemble. And

[0005]

According to the fence of the present invention, which solves the above-mentioned problem, a support pin which is perpendicular to the plane of the fence is fixed to the groove of a column having a vertical groove on the side. A vertical frame member connecting the column-side ends of a plurality of vertically arranged beams is engaged with the lower end thereof, and the upper end of the vertical frame member is engaged with the column. I do.

According to a second aspect of the present invention, in the fence according to the first aspect, a downward U-shaped notch is formed at a lower end of the vertical frame member so as to be fitted to the support pin, and an upper end of the vertical frame member is covered on an upper end of the column. It is characterized by being engaged with the column by the cap.

According to a third aspect of the present invention, in the fence of the first aspect, the column is divided into two divided columns on the front side and the rear side, and the concave groove is formed as a gap between the two.

[0008]

In the above construction, the ends of a plurality of beams are connected by a vertical frame member during assembly. The vertical frame member connected to the end of the beam is placed on a support pin fixed to the groove of the column, and then the upper end of the vertical frame member is engaged with the column.
This completes the connection of the beam to the column. No bracket is required in this configuration. And since the connection between the beam and the vertical frame material can be hidden in the groove of the support,
Even if the beam and the vertical frame material are connected by bolts, the bolts are not exposed. In addition, since the connection operation between the column and the plurality of beams can be performed collectively as the connection operation between the column and the vertical frame member, the operation of individually connecting the plurality of beams to the column is unnecessary.

According to a second aspect of the present invention, the U-shaped cutout at the lower end of the vertical frame member is fitted on the support pin, mounted thereon, and then the column is fixed to the column by a simple operation of capping. Therefore, the work of connecting the beam to the column is extremely efficient.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 4, reference numeral 10 denotes a fence post. The support column 10 is divided into two divided columns 11, a front divided column 11 (A) and a rear divided column 11 (B). Each divided column 11 has a flat surface 11a and a cylindrical surface 11b. It has a substantially semicircular cylindrical shape, and has a flat surface 11a with a flange portion 11c. The divided columns 11 are formed by bending a plate material and spot-welding the ends to be the flange portions 11c.
(B) has the same shape. The support pins 12 are fixed to the flat surface 11a of each of the divided columns 11 vertically by stud welding, that is, at right angles to the fence plane. The two split columns 11 form a concave groove 13 extending in the vertical direction on the side surface of the support column 10 by the flange portions 11c facing each other so as to abut on the flat surface 11a on the other side. It is preferable that the two divided columns 11 be welded together at several places where the flange 11c and the flat surface 11a are in contact with each other to be integrated.

[0011] The end of the three beam pipes 15 on the side of the column is attached to a vertical frame member 16 using a flat bar by bolts 17 and nuts 1.
8 are connected. The lower end of the vertical frame member 16 is formed with a U-shaped notch 16a that covers the support pin 12. The cap 19 to be put on the upper end of the column 10 is made of a casting or a resin product, and is fitted with the half-moon-shaped cylindrical portion 19 a to be inserted into the half-moon-shaped cylinder of each divided column 11 of the column 10 and the upper end of the vertical frame member 16. It has a rectangular cylindrical portion 19b for making it. Also, in order to fix the cap 19 to the post 10,
Hole 11d on the divided column 11 side and screw hole 19 on the cap 19 side
c, and the cap 19 is supported by
Fixed to.

The procedure for installing the fence having the above construction will be described. Both ends of three beam pipes 15 are connected to the vertical frame member 16 with bolts 17 and nuts 18 in advance. At the time of construction, first, a support column 10 in which two divided columns 11 are integrated is built at a predetermined interval. Next, the notch 16a at the lower end of the vertical frame member 16 to which the beam pipe 15 is connected is fitted to the support pin 12, and the vertical frame member 16 is placed on the support pin 12, and in this state, the cap 19 is put on the upper end of the column 10. And, as shown in FIG.
b fits the upper end of the vertical frame member 16, and the half-moon cylindrical portion 19 a of the cap 19 fits into the half-moon tube of each of the divided columns 11 of the column 10. Engages. Next, the bolt 20 is inserted from the hole 11 d and screwed into the screw hole 19 c of the cap 19, and the cap 19 is fixed to the column 10.

In the above-mentioned fence, the vertical frame material 16 is
As shown in FIG. 2, the bolt 17 and the nut 18 cannot be seen from the front because they enter the groove 13 of zero. Further, since the end of the beam pipe 15 is connected to the vertical frame member 16 by bolts 17 and nuts 18 and is rotatable, the beam pipe 15 can easily have a vertical angle when installed on a sloped road. .

In the above embodiment, three individual beams are rotatably connected to the vertical frame member. However, if it is not necessary to make a vertical angle, the beams are welded to the vertical frame member. May be fixed. When the beam is fixed to the vertical frame member, as shown in FIG. 5, the vertical frame member 16A on both sides and the beams 20 and 2 are fixed.
1 may constitute one member of the panel 23. In short, the fence to which the present invention is applied may have any structure as long as it has a plurality of beams, that is, horizontal members, and the pillar-side end of the beam is connected to the pillar via the vertical frame member.

The means for engaging the upper end of the vertical frame member with the column is not limited to the one using the cap 19 as in the embodiment, but a dedicated engaging member may be used or the upper end of the vertical frame member may be used. The upper end of the vertical frame member can be directly engaged with the column by forming an engaging portion or the like. Further, the concave groove formed on the side surface of the column is not limited to the one formed as the gap between the two divided columns as in the embodiment, but may be a single cylindrical body having a concave groove on the side surface or another structure. Can also.

[0016]

According to the present invention, the connecting portion between the support and the beam can be hidden in the concave groove on the side of the support, so that the bolts for connection are not exposed, and the bracket is exposed. This makes it possible to obtain an aesthetically pleasing fence. In addition, since the connecting operation between the support and the plurality of beams does not need to be performed for each beam, assembly is easy. Even if the number of beams is large, the amount of work for assembling does not increase, which is particularly effective when the number of beams is large.

According to the second aspect, since the upper end of the vertical frame member can be engaged with the support simply by covering the cap, the work of connecting the beam to the support is more efficient. Also, there is no need to use a separate component to engage the upper end of the vertical frame member with the column, and the structure for engaging the upper end of the vertical frame member with the column can be extremely simplified.

According to the third aspect, the support is divided into two parts, the front part and the back part, and a concave groove is formed as a gap between the two, so that it is easy to obtain a concave groove having a desired size and shape.
