Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a fence, and more specifically, to an improvement of a connection mechanism between a support and a tensioning member in a fence.

[Prior Art] Conventionally, various connection mechanisms have been employed to connect the posts of a fence or the like with a tension member such as a wire mesh or a rim. For example, the one described in Japanese Utility Model Publication No. 51-19810 has semicircular mounting ears protruding from both sides of a pipe serving as a support, and a square pipe serving as a fence rod is attached to the mounting ears via a connecting metal fitting. However, when attaching mounting ears to a post, the belt-shaped metal fitting that is integral with one of the mounting ears is wrapped around the support, and the other mounting lug is attached to the circumference provided on the band-shaped metal fitting. Since it is fixed to the pillar through a long hole in the direction, it is necessary to wrap the band-shaped metal fitting around the pillar and to fix it in the wrapped state.
Providing the elongated hole in the metal band fitting complicates the structure of the metal band fitting, and the processing becomes complicated, resulting in an increase in cost.

(b) Due to the provision of the elongated hole, the band-shaped metal fitting is subject to dimensional restrictions due to the elongated hole, that is, the other mounting lug, and in order to maintain strength, the width must be increased by the amount of the elongated hole.

c. After wrapping the band-shaped metal fitting around the support, the other mounting lug must be fixed to the support through the elongated hole, which is a cumbersome work.

There were other drawbacks.

[Problems to be solved by the invention] The problem of the present invention is to attach the metal band to the support without having to go through the troublesome work of wrapping it around the support or fixing the mounting rod to the support through a slotted hole. To make it possible to connect a tension member and a tensioning member very easily and reliably, and to easily construct a fence having corners.

[Means for Solving the Problems] In order to solve the above problems, in the fence of the present invention, straight rods made of bolts, threaded rods, etc. are connected and fixed to one side of the pillars erected on the ground at appropriate intervals. A rod is fixedly protruded, and a movable connecting rod located at the same height as the fixed rod is attached to a closed ring-shaped annular metal fitting fitted to the support while it is placed on the fixed rod, and a movable link is attached between each support. By attaching a connecting fitting having a connecting hole to the tension member placed in the tension member, and inserting and fixing the fixed rod and movable rod into the connection hole of the connecting metal fitting in the adjacent tension member, the support and the tension member can be connected. It is characterized by the fact that it is connected.

[Example] Hereinafter, an example of the present invention will be described in detail based on the drawings.
1, . . . are struts, 2, 2, . . . are double-barrel wire meshes as tension members, and the double-barreled wire mesh 2 is made by crossing a large number of vertical strands 3 with horizontal strands 4 perpendicular to them. A net is formed by welding and integrating the abutting portions by electric resistance welding, etc., and the net is inverted U.
It is formed to have two body parts 2a, 2a which are parallel to each other with an interval by being bent in a character shape, and a connecting part 2b which connects their upper ends. If necessary, the lower ends of the vertical strands 3 are extended and bonded to the opposing body parts to form connecting parts 2c, and connecting fittings 5 are attached to both ends of the double body wire mesh 2.

The connecting fitting 5 is provided with two upper and lower semi-cylindrical holding pieces 7a and 7b curved in opposite directions at both ends of the plate-like main body 6, and a connecting hole 8 is formed approximately in the center of the plate-like main body 6. The clamping pieces 7a, 7b are attached to the vertical wires 3, 3, which are located at the ends of the two body parts 2a, 2a and face each other in the same phase.
It is constructed between these vertical strands 3, 3 by elastically pinching them.

On the other hand, a linear connecting fixing rod 9 made of a bolt, a threaded rod, etc. is passed through the support column 1 having a circular cross section in a length projecting to one side, and is fixed by tightening a nut 10. 9, a closed ring-shaped annular fitting 11 is rotatably fitted, and the main body 12a is positioned on the side surface of the closed ring-shaped annular fitting 11 at the same height as the fixing rod 9. Connecting movable rod 1 bent horizontally so as to
2 is fixed by welding. This movable rod 1
2 is also constructed from a threaded rod. Further, the annular metal fitting 11 is provided with a fixing hole 13, and can be fixed by inserting a bolt into the fixing hole 13 and a fixing hole provided in the support column 1 at a predetermined rotational position.

The above-mentioned support 1 and the double-barrel wire meshes 2, 2 located on both sides thereof are connected to the fixed rod 9 and the movable rod 12 through the connection holes 8, 8 of the connecting fittings 5, 5 in the left and right double-barrel wire meshes 2, 2. These connecting fittings 5 are connected to the fixed rod 9 and the movable rod 12 by tightening and fixing them with two nuts 14 and 15, respectively. Here, if the fence is to be bent at a certain angle according to the topography, etc., the movable rod 12 may be directed in a predetermined direction by rotating the annular metal fitting 11, as shown in FIG. In this case, the movable rod is 12
can be rotated 360 degrees in any direction. Moreover, the annular metal fitting 11 can be fixed with the bolt 16 after its rotation direction is determined.

The connecting portions 2b and 2c are preferably formed into a curved shape so that when an impact force is applied to the body portions 2a, 2a, it can be absorbed by elastic deformation.In this case, the connecting portions 2b, It is desirable to form the connecting fitting 5 to have some degree of elasticity so as to cope with the change in the distance between the two body parts 2a, 2a due to the elastic deformation of the body part 2c, but it is necessary to consider the cushioning effect of the double-barrel wire mesh. If there is no such thing, the connecting fittings may be made of a material with high rigidity.In this case, conversely, the distance between the two body parts 2a, 2a can be kept constant, and the tension of the double body wire mesh can be maintained. It can be done very strongly.

As described above, according to the present invention, the connecting movable rod is attached to the annular metal fitting rotatably fitted to the support, and the connecting fixing rod fixedly attached to the support and the movable rod are connected to the connecting metal fitting of the tension member. I decided to connect it, so
By adjusting the rotation of the movable rod, the tensioning member can be connected to the support in any mounting direction, making it possible to form a fence with corners very easily.

In addition, when attempting to form a fence with corners in this way, the movable rods must be rotated around the posts while maintaining a predetermined height by some means until they are connected to the tensioning member in a predetermined direction. However, in the present invention, the movable rod is attached to an annular metal fitting, and this annular metal fitting is placed on the fixed rod and fitted into the column. The metal fittings can be reliably supported in a predetermined state by simply fitting the fixing rod into the column after attaching the fixing rod without attaching a special support member to the column. The rods are made of bolts, threaded rods, etc. and fixedly protrude from the columns, and only the connecting movable rods are rotatably supported by the annular metal fittings, so that the columns and the tension members can be easily connected. The configuration of the device for connection can be greatly simplified.

Furthermore, since the annular metal fitting is placed on the fixing rod and fitted to the support, the annular metal fitting can be wrapped around the support and fixed, as in the conventional example mentioned at the beginning. There is no need to provide long holes for fitting fixing rods, nuts, etc. in the annular fitting, and a simple annular fitting can be used, making the structure and installation extremely simple, and reducing the number of machining operations. This reduces the cost, and also prevents the strength of the annular metal fitting from decreasing due to the elongated hole. Moreover,
Since the annular fitting is not dimensionally restricted by the elongated hole, ie, by the fixing rod or nut, it can be formed to have a width independent of the fixing rod or nut. Furthermore, when fixing the annular fitting with a bolt that passes through the column after determining the direction, even if the fixing rod is installed so as to pass through the column, the position of the annular fitting and the fixing rod may shift vertically. Because of this, there is no positional conflict between the bolt and the fixing rod, and the bolt can be securely fixed.
