DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure such as a rim of a fence installed on a roadside of a road, around a building, or the like, and more particularly, to a supporting column and a hollow rim or a hollow connecting member at an end. The present invention relates to a mounting structure such as a rim of a fence having improved connection with a projecting frame or panel.

[0002]

2. Description of the Related Art Conventionally, as a mounting structure of a body edge or the like in a fence of this type, for example, as described in Japanese Patent Publication No. 3-12630, a complicated method of fastening a body edge by bolting is used. To solve problems such as requiring a long work, requiring a long installation time, and exposing the body edge mounting bolts to the outside, resulting in poor appearance and the possibility of the bolts being lost during on-site construction. There is known a body edge mounting structure in a fence for the purpose. The body edge mounting structure of this fence includes a pair of vertical support plates in which locking members fixed to the columns are arranged at an interval in the front-rear direction, and is separated from the columns at one end in the vertical direction of each support plate. The locking projection is provided at a position where the support plate is vertically projected.
As the protrusion protrudes from the outer surface of the support plate 2 as the distance from the protrusion for locking in the vertical direction increases, the protrusion for locking having a guide portion that is inclined so as to gradually increase the protrusion amount is formed,
A slit in the hollow body edge is pushed into the support plate 2 from above and below, and the inner edge of the slit is arranged to engage with the locking end of the locking projection. The engaging projection protruding into the body edge of the portion is arranged so as to engage with the end of the locking projection on the side of the pillar. According to the mounting structure, by performing a simple operation of simply pushing and fitting the hollow body edge from above and below to the locking metal fixed to the support,
Arrange the inner edge of the slit so as to engage with the locking end of the locking projection, so that the trunk edge does not fall out in the vertical direction,
Also, the engaging projection is engaged with the end of the locking projection on the support side.
R> so that it does not come out of the torso sideways,
It can be mounted easily and quickly, and the effect of solving the above-mentioned problem can be obtained.

[0003]

However, according to the mounting structure such as the rim of the conventional fence, the rim is supported by the upper edges of the locking projections on both the support plates of the locking metal. The contact area is small, and the relative movement in the front-rear direction is allowed, so that the mechanical coupling strength becomes extremely weak and the fitting condition between the locking fitting and the body edge becomes unstable. is there. Further, in order to prevent the relative movement between the latch and the torso in the longitudinal direction of the torso, an engaging projection that engages with the pillar-side end of the latching projection of the latch is provided on the torso. Is cut and bent, so that a cut-and-bend hole is exposed on the surface of the body edge, resulting in a problem that the appearance becomes ugly. Therefore, an object of the present invention is to provide a mounting structure such as a rim of a fence with a beautiful appearance in which the mechanical coupling strength is increased, the fitting condition is stabilized, and the appearance is beautiful.

[0004]

In order to solve the above-mentioned problems, a mounting structure such as a rim of a fence of the present invention is provided on opposing side surfaces of a column erected at a required interval with an interval in the front-rear direction. It has a pair of rectangular support plates to be arranged,
A support member provided with a triangular plate-like locking projection whose protrusion amount from the outer surface gradually increases from the upper side to the lower side in the middle of the horizontal ends of both support plates is fixed, and the beam pipe is attached to this support member. A connecting member consisting of a short beam pipe protruding from the end of the body edge or the end of the frame or panel formed at both end edges with ribs protruding inward at substantially the same interval as the interval between the two support plates. The bottom surface of the rectangular notch provided opposite to the edge of both ribs and the lower end surface of the locking projection are pushed and fitted through a longitudinal slit provided at the center of the lower surface. It is characterized in that it is provided so as to be able to contact, and the side surface of the notch and the side surface of the locking projection are provided so as to be able to contact.

Here, as the support, a support made of metal and having a circular cross section, a square shape, a rectangular shape, or another shape is used, and the arrangement interval is usually 2 to 3 m.
The support member is made of metal or engineering plastic, and is fixed to the column by welding, bolts, or the like. The two support plates of the support member have a height substantially the same as the outer diameter of the beam pipe, and are arranged in a wedge shape in which the upper and lower portions are narrower in parallel with each other. In order to facilitate the joining, it is preferable that the upper edge is bent inward at an appropriate angle. Also, both support plates are
In order to increase the mechanical strength, it is preferable to connect a part of the upper edge or to connect the base. When the upper edge is connected, it also contributes to an increase in the support area of the beam pipe. The locking projections of both support plates are preferably provided by cutting and bending the respective support plates, but may also be provided by welding a triangular plate-shaped locking projection piece to the support plate.
On the other hand, the beam pipe serving as a connecting member protruding from the body edge or the end of the frame or panel is made of metal or the like, and has a cross section of a circle, an oval, a square, a hexagon, or another shape. The opposing ribs of the beam pipe are provided in a parallel or wedge shape substantially at both intervals so as to be able to sandwich both support plates of the support member. Further, when the beam pipe is used as a rim, the slits and ribs of the beam pipe may be provided over the entire length. As the frame or panel, one with a lattice, one with a wire mesh, or the like is used.
