Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a protective fence installed on roads, etc.

(Prior Art) Conventionally, as a protective fence installed on a slope or a curved point of a road, for example, the one shown in Japanese Utility Model Publication No. 1983-5070 is known. In this structure, the brackets, connecting bolts, and nuts that connect the columns and beams are left exposed to the outside, which spoils the aesthetics and has low commercial value.In addition, fingers and clothes can get caught on these protruding objects. There is a risk that
The contact area between the column and the bracket is small, the strength of the connection is weak, and there is a large gap between the end of the beam and the surface of the column, leaving the beam end open. However, there were problems such as rainwater entering the beam through the opening at the end of the beam, making the beam susceptible to corrosion from within, and reducing the life of the beam.

(Purpose of the invention) The present invention was made to solve these conventional problems, and it hides the bracket in the beam to improve the aesthetics and safety, and also improves the connection between the support and the bracket. The purpose of the present invention is to provide a protective fence that can significantly improve durability by increasing the strength of the beam and preventing rainwater from entering into the beam.

(Structure of the invention) The present invention is a protective fence in which a beam is connected to a post via first and second brackets so that the angle can be changed vertically and horizontally. The first bracket has a corresponding column connecting portion, and the column connecting portion is connected to the column via an elongated hole in the circumferential direction of the column and a connecting device so that the position can be changed freely, so that the angle of the first bracket with respect to the column can be changed freely. A second bracket is connected to the first bracket via a horizontal axis.
The brackets are connected to each other so that the angle can be changed in the vertical direction, and both brackets are housed within the end of the beam, and this beam is connected to the second bracket via a connector, and the end of the beam is connected to the inner periphery of the end of the beam. It is characterized by being provided with a sealing material that closes the gap with the support column surface.

(Example) In FIGS. 1 to 4, a column 1 is formed into a cylindrical shape, a lid 11 is fixed to the upper opening, and radial connection holes are formed at one to several places in the vertical direction of the circumferential wall of the column. 12 are provided. The beam 2 is formed into a cylindrical shape, and an elongated connecting hole 21 is provided in the bottom surface near the end thereof.

The first bracket 3 includes an arc-shaped column connecting portion 31 corresponding to the surface shape of the column 1, and a column connecting portion 31.
A pair of parallel second bracket connecting portions 32 are connected to each other on both sides of the supporting column, and the supporting column connecting portion 31 is formed into a substantially U-shape in plan view.

The second bracket 4 has an arcuate beam connecting portion 41 that curves along the inner surface shape of the beam 2 at the lower part.
, a pair of first bracket connecting parts 42 facing each other in parallel on both sides thereof, and an arcuate reinforcing part 43 curved along the inner surface shape of the beam 2 at the upper part. A screw hole 44 for beam connection is provided in the beam connecting part 41 at the lower part of the beam connecting part 41, and the connecting part 42 is connected to the connecting part 32 of the first bracket 3 so as to be vertically rotatable via the horizontal shaft 5, that is, the angle can be changed freely. connected.

The sealing material 6 is made of rubber or soft plastic material and is formed into a cylindrical shape with a predetermined thickness along the inner surface of the beam 2, and one end surface 61 of the sealing material 6 is formed in a shape that follows the surface of the support column 1. . Third
The bracket 7 has a connecting part 71 corresponding to the surface shape of the support column 1 at one end of a cylindrical sealing material holding part 72, and the connecting part 71 has an elongated hole corresponding to the elongated hole 33 of the first bracket. 73 is formed, and the sealing material holding portion 72 of this third bracket 7
A sealing material 6 is fitted onto the outer surface of the inner surface of the inner surface of the outer surface of the outer surface of the outer surface of the outer surface of the inner surface of the outer surface of the inner surface of the outer surface of the inner surface of the inner surface of the inner surface of the inner surface of the inner surface of FIG.

When assembling the protective fence, for example, a plurality of posts 1 are erected at predetermined intervals on the side of the road, etc., and a third bracket 7 is installed at a predetermined location on the surface of each post 1.
The connecting portions 71 and 31 of the first bracket 3 and the first bracket 3 are connected by a connecting bolt 8 in an overlapping state.
At this time, since each connecting portion 71, 31 is formed in an arc shape corresponding to the surface shape of the support 1, the support 1
The surfaces of the brackets 7 and 31 are brought into close contact with each other through surface contact, and both the brackets 7 and 3 are firmly connected to the support column 1 without wobbling.

At the time of this connection, a screw hole is provided in the support 1,
The first bracket 3 may be connected by screwing a bolt into this screw hole, but generally, as shown in the figure, a bolt insertion hole 12 is provided in the column 1, and a pair of third brackets arranged on both sides of the column 1 are connected. 7 and a pair of first brackets 3 with a common connecting bolt 8.
Connect and fix by. Note that the third bracket 7 and the first bracket 3 may be formed integrally.

After connecting the brackets 3, 4, and 7 to the support column 1, the ends of the beam 2 are sequentially fitted onto the second bracket and the sealing material 6, and the sealing material 6 and each of the brackets 3, 4, and 7 are attached to the beam 2. The connecting screw 9 is inserted into the screw hole 44 of the second bracket 4 through the bolt insertion hole 21 from the lower surface of the beam 2.
This beam 2 is connected and fixed to the second bracket 4.

In this way, a predetermined protective fence is assembled by arranging the beams 2 between the columns 1 and connecting the ends of each beam 2 and the sealing material 6 to the columns 1 via the brackets 3, 4, and 7. . In this case, each bracket 3, 4, 7 is completely hidden within the end of the beam 2, and the head of the connecting screw 9 only slightly protrudes from the lower surface of the beam 2, so that the output part protrudes at the connecting part. There are fewer items, there is no risk of clothes getting caught, and safety is improved.
You can get something that is also aesthetically pleasing. Note that it is also easily possible to use a countersunk screw for the screw 9 so that its head does not protrude from the surface of the beam 2.

Furthermore, in the above configuration, by processing the end surface of the beam 2 in advance into a shape that follows the surface of the support column 1 and bringing the end surface into contact with the support column 1, it is possible to theoretically create a gap between the support column 1 and the beam 2. However, in reality, the end face of beam 2 is connected to support 1.
It is extremely difficult to process the shape into a shape that exactly matches the surface of the beam, and due to the error between the distance between the supports 1 and the length of the beam 2, there is an unavoidable gap between the support surface and the beam end surface. occurs.

However, by providing the sealing material 6 within the end of the beam 2 as described above, the gap is closed and rainwater etc. are prevented from entering into the beam 2 from between the support 1 and the beam 2. . Moreover, by closing this gap, the requirement for processing precision of the end face of the beam 2 is relaxed, and the manufacture of the beam 2 and the like becomes easier.

Note that the effect of closing the gap above is particularly noticeable in the fourth
This is noticeable when constructing a fake wooden fence as shown in the figure. That is, when constructing a pseudo-wooden fence, a wood-like uneven pattern is formed on the surfaces of the posts 1 and beams 2. Incidentally, a tree ring pattern is attached to the surface of the lid body 11 at the upper end of the support column 1. When connecting the beam 2 to the support column 1 whose surface has an uneven pattern in this way, it is inevitable that irregular gaps will be created between the support column surface and the end face of the beam. In such a case, by providing the sealing material 6, even irregular gaps can be easily closed, rainwater etc. can be reliably prevented from entering the beam 2, and each of the brackets 3,
4 and 7 are housed in the beam 2, and a fake wooden fence with high commercial value can be obtained without spoiling the beauty of the artificial wooden fence.

Furthermore, since the first bracket 3 and the third bracket 7 are connected to the elongated holes 33, 73 in the circumferential direction of the column via bolts 8, when installing the above-mentioned protective fence at a curved point, it is possible to By connecting the first bracket 3 by rotating it by a predetermined angle in the horizontal direction around the support 1, as shown by the dotted chain line,
The beam 2 can be horizontally inclined at a predetermined angle with respect to the support column 1 to follow the above-mentioned curve.

Furthermore, when installing the above-mentioned protective fence on a slope of a road, the second bracket 4 is rotated around the horizontal axis 5 with respect to the first bracket 3 connected to the support post 1, as shown by the two-dot chain line in FIG. By changing the connection angle between both brackets 3 and 4, the support 1 of the beam 2 fitted externally to this second bracket 4 can be adjusted.
The connection angle can be changed arbitrarily. In this case, the end of the beam 2 may be cut at a predetermined angle depending on the slope and the end may be brought into contact with the surface of the support 1, but the upper and lower sides of the end of the beam 2 may be By making a large cut in the
Flexibility can be exhibited, the angle can be easily adjusted, and versatility can be improved. In addition, even if the cut at the end of the beam is made larger and the beam 2 is installed at an angle with respect to the support 1, the gap between the support 1 and the beam 2 can be closed by the sealing material 6, and the sealing performance is improved. It won't hurt.

(Effects of the invention) As described above, the present invention can be suitably installed on flat land, sloped land, and curved land by connecting the column and the beam through the first and second brackets. Moreover, each bracket is hidden within the end of the beam, eliminating any external protrusions.
Not only can the aesthetics be greatly improved, but there is no risk of fingers or clothes getting caught, and it is also useful for improving safety. In particular, the sealing material provided inside the end of the beam can close the gap between the support and the beam, prevent rainwater from entering the beam, prevent corrosion from inside the beam, and provide excellent durability. You can get something.
