Description

[Detailed explanation of the idea] The present invention relates to a road protection fence.

Conventionally, road protection fences are constructed by erecting multiple posts in a row at appropriate intervals, brackets with groove-shaped cross sections are attached to the opposing side walls of adjacent posts, and horizontal beams are installed between the posts. Both ends are fitted into brackets and secured with bolts.

However, in such conventional road protection fences, the brackets have a simple cross-sectional groove shape into which the ends of the horizontal beams can be inserted, so when bolting the horizontal beams to the brackets attached to the pillars, the bolting process is difficult. The disadvantage is that the horizontal beams must be supported manually, which takes time and effort.

In addition, especially when the diameter and wall thickness of the horizontal beams are increased in order to increase the strength of the protective fence, the horizontal beams are heavy and it takes a lot of effort to manually support the horizontal beams during the bolting process. It has a bad flaw.

In view of these conventional drawbacks, the present inventor has developed a road-use product that eliminates the above-mentioned drawbacks by forming a receiving part for temporarily supporting the end of the horizontal beam inside the bracket with a groove-shaped cross section. It provides a protective fence.

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

In the drawings, reference numeral 1 denotes a support column, which is an elongated body made of metal and having an appropriately shaped cross section such as circular or rectangular.

Further, a plurality of pillars 1 are erected in rows at appropriate intervals.

Reference numeral 2 denotes a horizontal bar, which is an elongated body made of metal and having an appropriate shape such as a circular or square cross section.

Further, the horizontal beam 2 is extended between the columns 1, 1, and both ends thereof are bolted to the column 1 via brackets 3, which will be described later.

In addition, between the pillars 1 and 1, there are multiple horizontal bars 2゜2...
When the horizontal bars 2.2 are arranged vertically in parallel, a bar or panel may be appropriately attached between the upper and lower horizontal bars 2.2.

The bracket 3 is made of metal and has a cross-sectional groove shape into which the end of the horizontal beam 2 can be inserted.

The bracket 3 has a column attachment part 31 formed at its end, and the column attachment part 31 is brought into contact with the side wall of the column 1 and bolted.
It is designed to be attached to the support column 1 by welding or the like.

It is preferable that the strut mounting portion 31 is curved along the side wall of the strut 1 as shown in FIG. 3, since the bracket 3 can be stably attached to the strut 1.

Further, on the inside of the bracket 3, a receiving part 32 for temporarily supporting the end of the horizontal beam 2 is formed integrally with the bracket 1 in advance.

For example, in the case of FIGS. 2 to 4, the receiving portion 32 is connected to the bracket 3
The opposing surfaces of the protrusions are recessed inward.

Further, the receiving part 32 may be a plate piece in which the opposing surfaces of the bracket 3 are cut out and bent inward as shown in FIGS. It may also be formed by a plate piece extending between the opposing surfaces.

In addition to the above, the receiving part 32 may have any shape as long as it can fit the end of the horizontal bar 2 into the bracket 3 and support the end of the horizontal bar 2, and the shape is not particularly limited. do not have.

The brackets 3 are attached to the opposite side walls of the adjacent columns 1, 1, and normally, as shown in FIG. 3, the column mounting portions 31.
31 is abutted, and one bolt 4 is attached to the column mounting part 31.3.
1 and the support 1, and a nut 5 is screwed onto the bolt 4 and attached.

Further, the distance between the receiving parts 32, 32 of the brackets 3, 3 attached to the opposing side surfaces of the adjacent columns 1, 1 is made smaller than the length of the horizontal beam 2 at least.

In addition, in order to install the horizontal beam 2 between the adjacent columns 1, 1, first insert one end of the horizontal beam 2 into the bracket 3 of one of the columns 1 from below, and then insert the one end into the bracket 3 inside the bracket 3. Place it on the receiving part 32 of the bracket 3 and push it all the way into the bracket 3.

Next, the other end of the horizontal beam 2 is shifted toward the bracket 3 side of the other support column 1, and is inserted into the bracket 3 and placed on the receiving part 32 inside the bracket 3.

That is, both ends of the horizontal bar 2 are inserted into the brackets 3, 3, and the horizontal bar 2 is temporarily supported by the receiving portions 32,32.

Next, both ends of the horizontal beam 2 and the brackets 3 are fixed with bolts 6 and nuts 7, respectively.

As detailed above, the road protection fence of the present invention has brackets 1 to 1.
A receiving part is formed on the inside of the horizontal bar to temporarily support the end of the horizontal bar, so when both ends of the horizontal bar are inserted into the brackets of adjacent columns, the horizontal bar is temporarily supported by the receiving part, and the horizontal bar is temporarily supported. The horizontal beams can be bolted to the brackets, requiring no labor or effort during construction.

In addition, especially when the horizontal beam is heavy, it is possible to reduce the amount of labor required to support the horizontal beam manually during the work of bolting the horizontal beam.
It is extremely effective.

Furthermore, since the receiving part is formed integrally with the brackets 1 to 1 in advance, both ends of the horizontal beam can be temporarily supported by simply attaching the bracket to the support, which saves time and effort for assembly. Coupled with bolting the bracket and the horizontal beam, the end of the horizontal beam can be firmly fixed in a stable state by the bracket I and the receiving part.

Furthermore, since both ends of the horizontal beam are inserted into the bracket from below and temporarily supported by the receiving parts, both ends of the horizontal beam can be quickly and easily temporarily supported within the bracket and bolted together, improving assembly work. It is possible to improve the
