Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to a fence fixing device, and particularly to a device for fixing a fence face material of a well mesh to a support.

(Prior Art) For safety fences for sidewalks and boundary fences for land, fences are often used in which posts are erected on the ground and face materials are fixed to the posts using fixing fittings. There are various types of fences, one example of which is known as a well mesh fence.

When assembling such a well mesh fence, as shown in FIG. The frame line W is fixed.

(Problem to be solved by the invention) However, in conventional fences, the front and back sides have different designs, which not only is aesthetically undesirable, but also causes the head of the bolt SB to protrude from the surface of the support column 1, impairing the appearance. If used as a fence in a playground or park, it may cause injury.

Also, since the bolts are tightened to the pillar 1,
The bolt holes cause cross-sectional defects in the support column 1 and cause corrosion.

Furthermore, many parts are required during installation, resulting in poor work efficiency.

In view of these problems, the present invention aims to provide a fence fixing device that has the same design on both sides, can be easily assembled with a small number of parts, and can provide a large fastening force. .

(Means for solving the problem) As a result of intensive research to solve the above-mentioned problem, the inventor of the present invention found that when connecting and fixing the face material to the erected fence pillars, the upper and lower sides of the pillars in the direction in which the fence is installed are If a dovetail groove is provided that extends into the dovetail groove, and the distal end leg of the fixing fitting with deformability is installed in the dovetail groove and expanded and deformed by the screw axial force of the bolt, the problem when fixing with a through bolt can be solved. We focused on the fact that this problem could be solved, and completed the present invention.

In other words, the fence fixing device according to the present invention is a device for fixing a fence plate to a post using a fixing metal fitting, in which a dovetail groove extending vertically is formed on the side surface of the post in the direction in which the fence plate is stretched. On the other hand, the fixing fittings for fixing the fence paneling are made by bending a single metal plate into a U-shape, bending both legs extending from the base inward, and overlapping both ends to form an intermediate recess. a frame member, a nut inserted between the base portion of the frame member and the intermediate recess, and a screw inserted from outside the base portion of the frame member, the end of which extends while being threadedly engaged with the nut, abuts the intermediate recess. It consists of a bolt that can move forward and backward, and a pair of end legs of the frame material are inserted into the dovetail groove.
The threading of the bolt presses the intermediate concave portion, and the pair of tip leg portions are pushed apart to both sides within the dovetail groove and are prevented from coming off.

(Function) In the present invention, a dovetail groove extending vertically is provided on the side surface of the support in the direction in which the fence is tensioned, and the end leg of the fixing fitting is installed in the dovetail groove and expanded and deformed by the axial force of the bolt. Since the fixing metal fittings are set on the side of the column, the fixing fittings do not protrude from the front and back surfaces of the column as in the case of fixing using conventional through bolts, and sufficient fastening force can be applied. can get.

(Example) Hereinafter, the present invention will be described in detail based on specific examples shown in the accompanying drawings.

Fig. 1 is a front view of a fence assembled based on the present invention.As shown in Figs. 3 and 4, the pillar 1 has a so-called dovetail groove on the side, which has a narrow entrance but an enlarged interior. 11 are formed in the vertical direction. Moreover, a so-called well mesh panel is used as the face material P of the fence, which is formed by welding the joint portions of horizontal lines W1 and vertical lines W2 arranged above and below.

Since it is desirable that such a well mesh panel P is attached and fixed to a support so that it has the same design when viewed from the front or back, the fixing device 2 of the present invention is applied, and in the drawings, the middle part is the same as that of the present invention. It is fixed with a fence fixing device 2 according to the above.

Fig. 2 is an enlarged view of the fence fixing device 2 (however, only one side is shown in use in the figure);
FIG. 3 is a cross-sectional view taken along the - line, and FIG. 4 is a cross-sectional view showing the state shown in FIG. 3 before fixing.

In the figure, the fence fixing device 2 is constructed by combining the dovetail groove 11 and a fixing metal fitting.
As shown in FIGS. 5 and 6, in this fixture, one metal plate is bent into a U-shape, and both leg portions 32, 32 extending from the base portion 31 are bent inward, and both ends of the metal plate are bent inward. are overlapped to form an intermediate concave portion 33 to form a frame material 3, and the base portion 31 of the frame material 3 and the intermediate concave portion 33
A taper nut 4 is inserted between them, and the tip of a bolt 5 is inserted from the outside of the base portion 31 of the frame material 3, so that the tip of the bolt 5 that extends while being threaded with the nut 4 can come into contact with the intermediate recess 33. It is configured.

To assemble the fence, as shown in FIG. 4, after inserting the end vertical line W2 of the panel P into the dovetail groove 11 extending vertically on both sides of the support column 1 in the direction in which the panel P is stretched, A pair of tip leg portions 32, 3 of the frame member 3 at an arbitrary position with respect to the dovetail groove 11.
2 is inserted, the end vertical line W2 of the panel P is positioned between the intermediate recess 33 and the dovetail groove 11, and then the bolt 5 is screwed in, the intermediate recess 33 of the frame member 3 is pressed, and the frame member As shown in FIG. 3, the pair of distal end legs 32, 32 of the panel P are pushed out to both sides within the dovetail groove 11 and prevented from coming off, and the panel P is inserted between the intermediate recess 33 and the dovetail groove 11. The end vertical line W2 is clamped and fixed.

(Effects of the invention) As is clear from the above explanation, according to the invention, when assembling a fence by connecting and fixing the fence surface material P to the erected fence pillars 1 using fixing fittings, the pillars 1 and The fence surface material P is connected using a dovetail groove 11 that extends vertically on the side surface of the pillar 1 in the fence installation direction.
is provided, and the tip leg portions 32, 32 of the fixing metal fitting with deformability installed in the dovetail groove 11 are attached to the bolts 5.
Since the screw is expanded and deformed by the axial force of the screw, the problems associated with fixing using a through bolt can be solved.

That is, the installation of the panel to the support can be done extremely easily and quickly with a small number of parts.

In addition, instead of tightening bolts to the column from the front or back, we use fixing hardware that extends from the center of the column parallel to the panel surface, allowing panels to be installed with the same design on the front and back, greatly improving the quality of the appearance. Not only that, but the cross-sectional loss of the support column will also be eliminated.

Furthermore, the pair of legs of the frame material can be inserted into the dovetail groove on the side of the column from any part, and the mounting position can be set freely, so unlike conventional methods, bolt holes can be pre-drilled in the column at the factory. Since no machining is required and the fixing position can be selected according to the site conditions, on-site construction is extremely easy.
