In order to achieve the above-mentioned object, the present invention provides a fence panel having a vertical rail portion at the longitudinal end of a horizontal rail and having a female screw at the lower end of the vertical rail portion, and at least one of them. A pillar having a groove portion capable of receiving the vertical rail portion on its side surface and provided with a receiving rib for supporting the vertical rail portion in the groove portion, and a post threaded to the female screw of the vertical rail portion supported by the receiving rib. And a screw member that Alternatively, a male screw may be provided on the lower end of the vertical rail portion so that the male screw is projected downward from the receiving rib and screwed with the screw member.

[0005]

In the present invention, a groove for accommodating the end of the fence panel is provided on both side surfaces except the support of the terminal, and a receiving rib is provided in the groove. Therefore,
The fence panel can be stably supported by the receiving ribs simply by putting the fence panel in the grooves of the left and right columns. Since the vertical rail at the end of the fence panel has a female thread or a male thread at the lower end, a screw member consisting of a bolt or a nut is screwed into these, and the fence panel can be swung to the left or right in this state. With the panel stably supported, the angle can be changed in a considerable angle range in the horizontal plane with the screw member as a fulcrum. After adjusting the angle in this way, the fence panel is connected to the column by tightening the screw member. Therefore, it is possible to extremely easily realize a freely installed state corresponding to the R corner or the corner with only one bolt or nut. In addition, since the end of the fence panel is accommodated and supported in the groove of the strut, and the screw member is below the receiving rib in the groove and does not project to the outside, it is aesthetically pleasing in combination with the unique shape of the strut, fingers and clothing. It is safe without the danger of being caught.

[0011]

In order to obtain the road fence according to the present invention, a fence panel 2 having vertical rail portions 2b, 2b provided at both longitudinal ends of a required number of horizontal rails 2a is prepared, and the vertical rail portions 2b, 2b are previously formed. Drop it into the grooves 5 and 5 of the upright columns 1 and 1. Since the receiving ribs 6 and 6 project in the middle of the groove portions 5 and 5,
The vertical rail portions 2b, 2b are automatically and stably supported by these receiving ribs 6, 6, so that the fence panel 2 is set at a predetermined height level without requiring any special jigs. . Then, in this state, in the first embodiment, the bolt as the screw member 3 is received in the notch groove 60 of the rib 6 and screwed into the female screw 40 of the seat portion 4 provided at the lower end of the vertical rail portion 2b. Well, now the fence panel 2 is connected to the pillar 1.
In the second embodiment, when the vertical rail portions 2b, 2b are placed on the receiving ribs 6, 6, the male screw 42 projects from the receiving rib 6, so that a nut as the screw member 3 may be screwed onto the male screw 42.

The road fence is not limited to a straight line in plan view, but it is necessary to have an angle depending on the curve of the road. When the positions of the grooves 5 and 5 are fixed with respect to the columns 1 and 1, in the method of connecting to the columns with bolts from the direction perpendicular to the axis of the vertical rail of the fence panel 2, the fence panel 2 is used.
Can only be oriented in one direction. However, in the present invention, the receiving ribs 6 not only function as supporting means for the vertical rail portion 2b but also function as a rotation fulcrum in cooperation with the screw member 3, so that the receiving ribs 6 can be oriented at an arbitrary angle. it can. That is, in the first embodiment, when the fence panel 2 is shaken in a desired direction while the screw member 3 is appropriately loosened (the screw member 3 may not be screwed in the second embodiment), the groove portions 5 and 5 are formed. Since the vertical rail portion 2b has an arc shape and also has an arc shape, as shown in FIG.
The angle α changes smoothly along the arcuate groove surface with the fulcrum as a fulcrum, and therefore, the angle can be easily adjusted without the need for the groove portions 5 of the adjacent columns 1 and 1 to face each other. With the angle thus adjusted, the screw member 3
By tightening the
1 is connected and fixed. Therefore, it is possible to connect the fence panel 2 to the columns 1 and 1 very easily and quickly while freely corresponding to the R corners and corners.

In the road fence thus obtained, the joint element is one bolt or nut and is attached below the receiving rib 6 in the groove portion of the strut 1, so that it can be seen from the front or the plane of the road fence. Can't see at all. For this reason, the appearance is extremely good, and it is possible to form a sleek and elegant aesthetic rather than a structure, and it is possible to achieve harmony with the landscape. Since no special metal fittings such as brackets are required as joints and the number of parts can be greatly reduced, even if the columns 1 and the fence panel 2 are made of high-grade materials such as aluminum and stainless steel, there is almost no increase in cost. The aesthetics can be further enhanced.

[0014]

According to the present invention described above, a fence panel in which an arbitrary number of horizontal rails 2a have vertical rail portions 2b at the longitudinal ends and female screws 41 or male screws 42 are provided at the lower ends of the vertical rail portions 2b. 2, a column 1 having a groove 5 capable of accommodating the vertical rail 2b on at least one side surface, and a support rib 6 provided in the groove 5 for supporting the vertical rail 2b; Since it has the screw member 3 to be screwed into the female screw 41 or the male screw 42 of the supported vertical rail portion 2b, the assembling work of the support 1 and the fence can be performed very easily and quickly,
In particular, since the fence panel 2 can be arbitrarily angled in the horizontal plane around the screw member 3 screwed to the lower end of the vertical rail portion 2b, it can be freely adapted to the R corner or the corner portion. . Moreover, the screw member 3 is the receiving rib 6
It is underneath and has no protrusions on the outside, so it has a very beautiful appearance and there is no need to worry about catching fingers or clothes. And while there is such an effect, the number of parts is minimized without using a bracket, and the assembly workability is good,
Excellent effects such as a significant cost reduction can be obtained.
