Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a protective fence in which a fence body is attached between each of a plurality of posts planted at appropriate intervals.

(Prior Art) Recently, there has been a demand for protective fences that can be installed on slopes and curves on roads.

Conventionally, as shown in FIG. 7, in a protective fence in which a fence body is attached between posts, the open end side of a bracket 3' having a substantially U-shaped cross section is attached to a post 1'. The body 2' has a mounting part 4' which is adapted to clamp the bracket 3' from above and below.
There was one in which the mounting portion 4' was pivoted to the bracket 3' via a pin 5' so as to be rotatable in the horizontal direction.

(Problem to be Solved by the Invention) However, in such a conventional device, the upper and lower ends of the bracket 3' on the side of the fence 2' have an angular shape. Bracket 2' is rotatable in the horizontal direction and can accommodate curves on roads, etc., but in the vertical direction, bracket 3' is rotatable.
There was a problem that there was no flexibility between the fence body 2' and the mounting part 4', and that the fence body 2' could not be rotated with respect to the support column 1', making it impossible to install it on a slope.

(Means for solving the problems) The present invention was devised in view of the problems of the prior art, and as a result of intensive ingenuity, the above-mentioned problems were solved.It can be adapted to curves of slopes and roads at the same time, and can be easily installed in any place. This provides a protective fence that can be installed in

The present invention will be described below with reference to the drawings.

In the drawings, 1 is a support, 2 is a fence, 3 is a bracket, and 4 is a mounting portion.

The support column 1 is made of metal, synthetic resin-coated metal, or the like, and its cross-sectional shape is not particularly limited, such as circular or rectangular.

A plurality of pillars 1 are planted on the ground at appropriate intervals, and brackets 3, 3 are protruded almost perpendicularly from the opposing sides between adjacent pillars 1, 1, respectively. Further, one or more brackets 3 are provided protruding from the side surface of the support column 1.

In Fig. 2, the fence body 2 is formed by a large number of vertical beams 22, 22 extending between the upper and lower horizontal beams 21, 21, but it may be made by combining the beams as appropriate, or by combining the beams with each other. It may also be a combination of a plate-like body and a plate-like body. At both ends of the fence body 2, mounting portions 4, 4 are provided to protrude almost perpendicularly to brackets 3, 3 protruding from the pillars 1, 1.

Incidentally, the mounting portion 4 may be provided to protrude from the support 1, and the bracket 3 may be provided to protrude from the fence body 2.

The bracket 3 has a substantially U-shaped cross section, consisting of opposing plate pieces 31, 31 and a folded portion 32. The open end 311 side of the plate piece 31 is attached to the support 1 or the fence body 2 by welding or the like, and the plate piece 31
Upper and lower corner portions 312, 312 on the folded portion 32 side of
is approximately arc-shaped.

Further, the arcs of the upper and lower corner portions 312, 312 of the plate piece 31 having a substantially circular arc shape are further extended toward the open end 311 side of the plate piece 31, so that the plate piece 31 as shown in FIG.
It is more preferable that the upper and lower end edges 313, 313 of 1 are formed in a substantially arc shape.

The mounting portion 4 consists of two plates 41, 41 arranged vertically and substantially parallel to each other, and is attached to the fence 2 or the support 1 by welding or the like, facing the bracket 3. The width between the plates 41, 41 is made slightly larger than the width of the plate piece 31 of the bracket, and the width between the plates 41,
A mounting hole 411 is bored in the.

Next, the construction method and function of the protective fence of the present invention will be explained. First, a bracket 3 is provided in advance at a desired position where the support post 1 and the fence body 2 face each other with the plate pieces 31, 31 vertically oriented, and the plate body 41, 41 is held horizontally and the mounting part 4 is provided protrudingly, and after a plurality of posts 1 are erected at predetermined positions at appropriate intervals, a fence body 2 is placed between the posts 1, 1. Next, insert the bracket 3 between the plates 41, 41 of the mounting part 4, insert the bolt 5 into the mounting holes 411, 411 of the mounting part 4 and the opening 33 between the plates 31, 31 of the bracket 3, and tighten the nut 6. The bracket 3 can be secured to the mounting portion 4 by using the following steps.

Furthermore, when the protective fence of the present invention is installed at a curved point on a road or the like, the fence body 2 may be rotated horizontally around the bolts 5. That is, in this case, the mounting portion 4 is rotated horizontally with respect to the bracket 3 about the bolt 5.

Furthermore, when installing the protective fence of the present invention on a slope, the fence body 2 may be rotated in the vertical direction. In this case, the mounting part 4 is rotated in the vertical direction along the substantially arc-shaped corner part 312 of the bracket 3, and
The bolt 5 is rotated within the opening 33 between the plates 31, 31 of the bracket 3.

Further, when the upper and lower edge portions 313, 313 of the plate piece 31 of the bracket 3 are formed into an arc shape continuously from the upper and lower corner portions 312, 312 of the plate piece 31 as shown in FIG. The mounting part 4 is rotated, and the bracket 3 and the mounting part 4 are mounted even more tightly.

Furthermore, when installing at a curve point or on a slope, the above-mentioned installation methods may be combined as appropriate.

(Effects of the invention) As detailed above, the protective fence of the present invention has a pair of brackets and mounting parts protruding from the pillars and the fence body at desired positions facing each other, and the upper and lower corners of the plates of the bracket The fence is shaped like an arc, and a bracket is inserted between the plates of the mounting part, and bolts are inserted through the mounting part and the bracket, so that the fence body can freely rotate horizontally and vertically relative to the erected posts. It can be installed to suit the curves of slopes and roads, and if a pair of brackets and mounting parts are provided in advance on the posts and fence bodies, all that is required is to attach the brackets to the mounting parts during construction. It also has excellent construction and workability.
