Description

[Detailed description of the invention] This proposal relates to a protective fence to be installed on the boundary of a farm or other site, around a water pond, on a road, or other areas.

Many of the protective fences that are constructed of columns that are planted on the ground and crosspieces installed between them have a structure that allows the crosspieces to be tilted and connected to the columns depending on the topography of the installation site. Conventionally, as a connection structure in which the fixed angle of the crosspiece member can be adjusted, firstly, the crosspiece member is rotatably attached with a pin to a bracket fixedly protruding from the support, and secondly, the bracket is rotatably protruded from the support. A typical example is one in which the crosspiece is rotatably attached with a pin.
The first type can only be rotated in one direction, so at points where the direction of installation changes, it is necessary to use supports whose brackets protrude in different directions, making it impossible to meet various demands. The second type allows adjustment in the vertical and lateral directions by changing the posture of the bracket, but the bracket only rotates on the center line of rotation relative to the column, and the direction of its protrusion cannot be changed. Therefore, in places where it is necessary to lay the crosspiece in a direction different from the protruding direction of the bracket, the crosspiece is rotated to the side of the bracket, so the area of these overlapping parts becomes smaller. The strength of the attachment point between the bracket and the crosspiece member becomes weak. Also, vertical,
The ones that can change the horizontal direction at the same time are also commercially available.
This is proposed in Japanese Patent No. 16502, but it has a complicated structure and a large number of parts, making it inconvenient to install, and it also has the disadvantage that the crosspiece member can only be connected to the top end of the support.

This proposal solves these problems and provides a protective fence in which the brackets are connected in any direction at any location on the support with a small number of parts. The bracket has a mounting part provided with a mounting hole consisting of an elongated hole extending into the bracket, and a clamping part extending parallel to both ends of the mounting part and having a coupling hole facing each other. The beam member is fixed to the pillar by a bolt and nut that are in point contact and passed through the pillar and inserted into the mounting hole, and the crosspiece member is fixed to the pillar by a connecting member that fits into the clamping part and is inserted into the coupling hole. It is characterized in that it is connected to the bracket.

An example of the present invention will be explained below with reference to the drawings.
In FIG. 1, 1 is a column, 2 is a bracket, and 3 is a crosspiece member. The column 1 and the crosspiece member 3 are formed of pipes, and a cap 4 is fitted onto the upper end surface of the column 1 which is planted on the ground surface. Fixed. The bracket 2 is formed by bending a metal plate into a U shape, and a mounting hole 6 formed of a long hole extending in the circumferential direction is provided in the mounting portion 5 at the semicircularly curved base end. Connecting holes 8, 8, which are also elongated holes, are provided oppositely in the clamping portions 7, 7 extending in parallel.

In the bracket 2 shown in FIGS. 2 and 3, a mounting hole 6 is provided over the entire length of a mounting portion 5, and both ends thereof are formed in such a length that they reach clamping portions 7, 7. The bracket 2 shown in FIGS. 4 and 5 is a modified example in which the mounting hole 6 is formed in a length extending from the center of the mounting portion 5 to one of the clamping portions 7, and the clamping portions 7, 7 are formed on a crosspiece member. It is curved to wrap around 3.

By inserting the bolts 10 into the holes 9 formed at predetermined positions of the strut 1 and the mounting hole 6 of the bracket 2 and tightening the nuts 11, the mounting portion 5 is brought into line or point contact with the outer peripheral surface of the strut 1. In this state, the bracket 2 is fixed to the column 1, and the ends of the crosspiece member 3 are fitted into the clamping parts 7, 7 of the bracket 2, and the holes 1 of the crosspiece member 3 are inserted.
The cross member 3 is fixedly or rotatably connected to the bracket 2 by inserting a bolt 13 into the connecting hole 8 of the clamping portion 7 and tightening a nut 14.

In the part indicated by the arrow A-A in FIG. 1, the horizontal direction is different from that of the crosspiece member 3 as shown in FIG. The direction in which the left bracket 2 projects from the support column 1 can be changed. That is, the adjustment range of the protruding direction of the bracket 2 is within a range of 90 degrees from the axial direction L of the bolt 10 to the directions R ₁ and R ₂ perpendicular to this, and this is the same for the right bracket 2. It is.

In the section indicated by the arrow B--B in FIG. 1, the crosspiece member 3 changes its direction by 90 degrees while sandwiching the support 1, as shown in FIG.

In the part indicated by arrow C in FIG. 1, the vertical direction of the crosspiece member 3 has changed, and by making the mounting hole 6 vertical and shifting the bolt insertion position from the center, the bracket 2 on the right side in the figure can be projected diagonally downward from the support column 1. The opposing brackets 2 of the low-lying supports 1 are made to project diagonally upwards by similar means.

When changing the vertical and horizontal protruding directions at the same time, it is sufficient to shift the bolt insertion position of the mounting hole 6 from the center and rotate the bracket 2 around the bolt 10.
The bracket 2 can be projected in any direction vertically, horizontally, or diagonally.

Although the connecting hole 8 is formed as a long hole so as to absorb the error in the spacing between the pillars 1, a round hole may also be used.
3. Instead of the connecting piece 15 consisting of the nut 14, a structure in which the connecting piece 15 is rotatably connected by a pin may be used. Furthermore, the support column 1, its cap 4, and crosspiece member 3 are made of metal such as iron or aluminum, or synthetic resin such as hard polyvinyl chloride, but the graft copolymer of ethylene, vinyl acetate, and vinyl chloride is weather resistant, Since it has particularly excellent impact resistance and cold resistance, it is suitable for the proposed protective fence installed outdoors, and if necessary, metal reinforcing wires may be embedded in the pipe wall.

As described above, the present invention forms parallel clamping parts at both ends of a semicircularly curved mounting part, provides a mounting hole consisting of a long hole extending in the circumferential direction in the mounting part, and has a coupling hole facing the clamping part. Using the bracket provided,
This bracket is fixed to the support by bolts and nuts passed through the support and into the mounting holes, and the crosspiece is fitted between the clamping parts, and a connecting piece consisting of a bolt or pin inserted into the connection hole is used to secure the bracket to the support. Since it is connected to the bracket with a bolt, the mounting part can be brought into line contact or point contact with the outer circumferential surface of the support without any processing other than providing a hole for the bolt to pass through the support, and the bolt insertion position of the mounting hole can be adjusted. By shifting the bracket, the bracket can be made to protrude in any direction vertically, horizontally, or diagonally, and since the mounting part is curved in a semicircle, it can be brought into contact with the column at the bolt insertion part and fixed without shaking. be. In addition, the crosspiece member is fixedly or rotatably connected by fitting into the clamping part of the bracket, and the bracket can be fixed to the support column with it protruding in any direction, so that it can be stacked parallel to the clamping part. The bracket can be fixedly protruded in the direction in which the bracket protrudes, and therefore the area of the overlapping portion is large, so that the mounting strength is large and the beam member can be firmly and stably supported by the bracket.
Furthermore, during installation or removal, the work is made easier by rotating the crosspiece in a plane perpendicular to the connecting piece, and the work is facilitated by rotating the crosspiece in a plane perpendicular to the connecting piece. A beam member extending in any direction can be erected at any location on the support with a small number of connecting members, and can be used to cope with complex topography.
