Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to a device for preventing the fence from falling off.

(Prior Art) For example, wire mesh fences and the like are often used to make boundaries clear between neighboring properties.

Usually, in this type of fence, a cut is formed on the lower surface of the tubular body rim along the entire length in the longitudinal direction, and both edges of the cut are folded inward to form an insertion groove, while the upper end of the wire mesh that becomes the fence surface For example, the edge is formed into an annular shape so that it does not come out downward from the insertion hole, and tension steel is attached to both edges of the wire mesh, and the upper end edge of the wire mesh and the upper end of the tension steel are inserted into the furring edge and into the insertion groove from the side. A structure is adopted in which the upper end of the tension steel is inserted into the support joint and the wire mesh is stretched.However, in this case, if the support is tilted along the fence surface for some reason, the structure There is a problem in that the outer end of the furring slips out of the support joint, detracting from the appearance of the fence.

Therefore, in conventional fences, for example,
As shown in Publication No. 12916, both edges of the insertion groove at the outer end of the sleeve are further bent inward to form a snap edge, which abuts and locks the upper end of the tension steel. On the other hand, a slip-off prevention device has been proposed in which the end of the flange is abutted and locked by a protrusion on the inner surface of the strut joint, thereby preventing the outer end of the flange from coming off from the strut joint. There is.

(Problem to be solved by the invention) However, in the above-mentioned conventional bulletin board slip-off prevention device, a notch is made in the lower surface of the outer end of the trunk, and after the tension steel is jointed to the strut joint, Since the outer edge of the edge is bent and formed by hitting the outer edge of the edge with a hammer, etc., and the tension steel and the edge are brought into contact and locked, not only tools such as a hammer are required, but also tools such as a hammer are required. Manual construction is required for each piece, and the assembly work is complicated and time-consuming.Moreover, in order to form a toe that securely contacts the tension steel, it is relatively large, for example, approximately half the diameter of the torsion. There was a problem that the strength of the retaining edge was weak.

In view of such problems, the object of this invention is to provide a device for preventing the Fuens furrow from falling off, which does not require tools such as a hammer and can reliably prevent the furrow from coming off with a simple operation.

(Means for Solving the Problems) Therefore, the Fuens furring retaining device according to the present invention has an insertion groove formed by folding inward both edges of a cut formed over the entire length in the longitudinal direction on the lower surface of the tubular furring. In the fence, the upper end of the tension steel and the upper edge of the fence surface are inserted into the tubular body rim and the lower surface insertion groove while being prevented from falling downward, and the upper end of the tension steel is jointed to the support joint part. A notch is formed on both edges of the insertion groove at a position outside the position of the tension steel, while an insertion edge is formed on both left and right sides of the upper trapezoidal locking piece, facing downward and inward. Each has a claw piece facing downward at a right angle, inserts the locking piece into the body rim, inserts the insertion edge into the folded parts of both edges, and then inserts the claw piece into the notch, allowing it to pass through the body rim. The gist is that when moving in the direction, the claw piece and the tension steel are brought into contact to prevent the rim from coming off.

(Function) When assembling the fence, insert the upper edge of the fence surface and the upper end of the tension steel into the tubular body edge and the lower insertion groove from the side to prevent it from falling out downward, and insert the insertion edge of the locking piece into the body. Engage with the outer edge of the folded part of the rim, and in this state push the locking piece inward from the outer edge of the flap along the folded part. When pushed in a specified distance, the claw of the locking piece will engage with the outer edge of the locking piece. Since it will naturally fit into the notch due to its shape, the upper end of the tensioned steel can then be joined to the support joint.

In this way, in the present invention, the locking piece is fitted to the outer end of the furring, so when moving in the direction of removal of the furring, the claws of the locking piece come into contact with the tension steel and prevent the furring from coming out. This will surely prevent the dropout.

In addition, the rim can be prevented from coming off simply by engaging the locking piece along the folded part and pushing it in.
No tools such as a hammer are required, and assembly is easy and time-saving.

Further, since a notch is formed at the outer end of the furring and the locking piece is fitted into the notch, there is no need for a large cut as in the conventional case, and the strength of the retaining portion is ensured.

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

FIGS. 1 to 6 show a locking device for a fencing furrow according to an embodiment of the present invention. In the figure, a T-joint section 8 is provided at the upper end of the column.
The end of the furring 4 and the upper end of the tension steel 9 are inserted into the joint part 8 between them, and the upper end of the tension steel 9 is fixed to the joint part 8 by a bolt 11, and the end of the furring 4 is fixed to the joint part 8 by a bolt 11. The parts are tightened and fixed by a joint part 8.

Further, the furring rim 4 has a generally tubular cross-section, and a cut is formed on the lower surface thereof over the entire length in the longitudinal direction, and an insertion groove 5 is formed by folding both edges inward. (Fence surface) The side edge of the wire mesh 10 is supported, and the upper end of the tension steel 9 and the upper edge of the wire mesh 10 are inserted into the furrow 4 and the insertion groove 5 from the side, for example, a ring on the upper edge of the wire mesh 10. The shape prevents it from coming off downward.

The outer end of the furring 4 is provided with a stopper device. In this retaining device, a notch 7 is formed at the outer end of the insertion groove 5 and both edge folded portions 6 of the body rim 4, and the upper surface 1 of the locking piece has a trapezoidal shape. Insertion edges 2 which are mutually tapered are curved downward and inward on both left and right sides of the locking piece, and claw pieces 3 are bent downward and at right angles at the bottom of the locking piece. 4, and the claw pieces 3 are fitted into the notches 7, and as described above, the locking pieces are fitted and fixed to the outer ends of the furring rim 4, When moving in the withdrawal direction (to the left in FIG. 5), the locking piece and the tension steel 9 come into contact to prevent the furring 4 from coming off.

Next, the assembly method will be explained.

When assembling the fence, first place wire mesh 1 on tension steel 9.
Attach the side edges of 0, the upper edge of wire mesh 10 and tension steel 9
The upper end of the sleeve is inserted into the furrow 4 and the insertion groove 5 from the side.

When the attachment of the furring 4 to the tension steel 9 and the wire mesh 10 is completed in this way, the both side insertion edges 2 of the locking pieces are locked to the outer ends of the both edge folded parts 6 of the furring 4 (Figs. 2 and 3).
In this state, the locking piece is pushed inward from the outer end of the furring 4 along the folded portion 6 (see FIG. 6B). At this time, as shown in FIGS. 1 and 2, since the left and right insertion edges 2 of the locking piece are mutually tapered, the claw piece 3 of the locking piece
is fitted into the notch 7 naturally and reliably by pushing the locking piece.

Finally, the assembly thus assembled is carried between the columns, and the upper end of the tension steel 9 is jointed to the column joint part 8.

In the slip-off prevention device of this embodiment as described above, since the locking piece is fitted into the outer end of the furring 4, when the furring 4 tries to move in the pulling direction, the locking of the furring 4 is prevented. The pieces come into contact with the tension steel 9, thereby reliably preventing the furring rim 4 from coming off.

In addition, with this retaining device, the armrest 4 can be prevented from coming off by simply engaging and pushing the locking piece along the folded portion 6 of the furrow 4, and there is no need for conventional tools such as a hammer. Furthermore, the assembly work is simple and the fence can be assembled quickly.

Furthermore, in this retaining device, a notch 7 is formed at the outer end of the furring 4, and a locking piece is fitted into this, so there is no need to form a large notch as in conventional devices. The strength of the retaining part is high, ensuring the strength to prevent it from coming off.

(Effect of the invention) As described above, according to the Fuens furrow retaining device according to the present invention, notches are formed in both edge folded parts of the outer end of the furrow insertion groove, and the locking piece is attached to the furrow. Insert the locking piece inward from the outer end, insert and engage the insertion edge of the locking piece into the folded part, and fit the claw piece of the locking piece into the notch,
When the furring rim moves in the direction of removal, the locking piece and the tension steel are brought into contact to prevent the furring rim from coming off.
It does not require tools such as a hammer, can be assembled easily and quickly, and has the effect of reliably preventing the rim from coming off.
