Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a structure for attaching panels between grids in a light metal fence assembled from extruded members such as aluminum.

(Prior Art) Generally, this type of fence has a frame structure in which upper and lower string members are erected on pillars planted in the ground, and a large number of lattices are arranged between the upper and lower string members. In addition, panels are often installed between the latticework to provide concealment.

In addition, as housing styles have become more Westernized, there has been a recent trend toward opening gardens so that they can be seen by passersby.
In some cases, panels are installed only at the top edges of the lattices, just enough to slightly block the view of the house from the street.

(Problem that the invention aims to solve) In such cases, it is necessary to prevent the panel from coming off, sliding down, wobbling, etc., but conventionally, separate fastening members such as screws are used. As a result, the work efficiency was extremely low.

(Means for solving the problem) The present invention was made in view of the above circumstances.
Without using separate fastening members such as screws,
This allows the panels to be stably connected to the grid with extremely simple work.

That is, the present invention provides a light metal fence in which a large number of lattices are arranged in a row between both upper and lower chord members installed on a support, and panels are provided between the lattices. A hanging piece that engages with the clamping piece is formed, and a standing piece is formed on the lower chord member,
A groove for locking the panel is provided in the lattice so as to be sunken from the surface, and projecting edges are formed on both sides of the opening of the groove, and the hanging pieces and the upright pieces fit into the bottom wall of the groove. The panel is fixed by forming a split groove and tightening a curved edge formed by crimping the projecting edge.

(Embodiment) The drawing shows an embodiment of the present invention, and first the frame of the fence will be explained.

In other words, in the frame of the fence, column 2
are planted, upper and lower chord members 3 and 4 are erected between the supports 2 and 2, and lattices 5 are arranged in rows at equal intervals between the upper and lower chord members 3 and 4, and the panel 6 is made up of each lattice 5, 4. It is attached to the upper end between 5 and 5. Each frame member 2, 3, 4, 5 and panel 6 are made of extruded aluminum.

The support column 2 is made of a hollow member with a rectangular cross section, and a screw pocket 8 is formed inside thereof at the center of the width of a front wall 7 facing the road. Further, both the upper and lower chord members 3, 4 and the lattice 5 are each formed into a hollow shape with a substantially rectangular cross section with four corners rounded. An upright piece 10 is provided in the center, and extension pieces 1 of the side walls 11 are provided at both ends of the lower chord member 4.
2 and 12 are installed vertically.

The lattice 5 has concave grooves 13, 1 at the center of the width on both left and right sides.
3, and projecting edges 14, 14 are formed on both sides of the opening of the groove 13. The panel 6 is in the form of an extruded material and has forked parts 15 and 16 at both the upper and lower ends, of which the upper forked part 15 has a pair of front and rear clamping pieces 15a and 15b that sandwich the hanging piece 9 of the upper chord member 3.
The rear clamping piece 15b is connected to the front clamping piece 15a.
It is formed longer than the

To explain the combination of the upper and lower chord members 3, 4 and the lattice 5, dividing grooves 17, 17 are provided in the hanging piece 9 of the upper chord member 3 and the upright piece 10 of the lower chord member 4, and the lattice 5
By inserting the lattice 5 into both the upper and lower chord members 3 and 4 through the bottom wall of the groove 13, and by tightening both edges of the opening of the lattice groove 13, as shown in FIGS. 5 and 6, The curved edges 18, 18 due to crimping are pressed against the hanging piece 9 and the upright piece 10. In this way, the lattice 5 is held at right angles to both the upper and lower chord members 3 and 4, and the upper and lower chord members 3 and 4 are strongly connected via the lattice 5.

Regarding the installation of the panel, since it is made of extruded material as mentioned above, the cutouts 19 and 20 where the upper and lower forked portions 15 and 16 are removed are provided at the four corners.
panel 6 due to the omission of the fork parts 15 and 16.
The end of the lattice 5 is inserted into the groove 13 of the lattice 5. Then, in the same manner as above, both edges of the opening of the groove 13 of the lattice 5 are crimped, and both curved edges 2 are formed by crimping.
1 and 21 are pressed against the ends of the panel 6.

In addition, a punch hole 22 is provided in the hanging piece 9 of the upper chord member 3,
Of the front and rear clamping pieces 15a and 15b of the upper fork 15 that engages with the hanging piece 9, the longer rear clamping piece 1
5b is crimped into the extraction hole 22, and its crimping protrusion 30 is pressed against the edge of the extraction hole 22.

When the panel 6 is installed in this way, the panel 6 engages with the groove 13 of the lattice 5 and the hanging piece 9 of the upper chord member 3, and this engagement is maintained by the strong pressing force of crimping, so that it does not come off. A stable mounting state of the panel 6 without sliding down, rattling, etc. can be obtained.

As described above, the steps for assembling the fence include assembling the upper and lower chord members 3, 4, the lattice 5, and the panel 6, and attaching the assembly to the support column 2. For its installation, upper and lower latching fittings 23 and 24 are used,
The upper hanging metal fitting 23 is fixed to both the upper chord member 3 and the post 2 with screws 25 and 26, but the lower holding fitting 24 is fixed only to the supporting post 2 with a screw 27, and the extension piece 12 of the lower chord member 4 is fixed to that It is hung on a metal fitting 24. Note that 28 is a base material for increasing the strength of screwing the upper hook 23 onto the upper chord member 3, and 29 is a cap at the upper end of the support column 2.

(Effects of the invention) As explained above, the present invention provides a light metal fence in which a large number of lattices are arranged between the upper and lower chord members installed on a support, and panels are provided between the lattices. A hanging piece is formed to engage with a clamping piece provided on the upper edge of the panel, an upright piece is formed on the lower chord member, and a groove for locking the panel is provided in the lattice by recessing it from the surface. , by forming projecting edges on both sides of the opening of the groove, forming split grooves on the hanging piece and the upright piece to fit into the bottom wall of the groove, and crimping the projecting edges. Since the panel is fixed by tightening the formed curved edges, the following effects are achieved.

The panel installation work is extremely easy, and the fence assembly work efficiency can be increased.

Since no members are required for attaching the panels, it is suitable for providing fences at low cost.

Both the upper and lower chord members are fitted and fixed to the lattice, and the clamping pieces of the panel engage with the hanging pieces, so the connection of the panel to the lattice is strong, effectively preventing the panel from wobbling, shifting, coming off, etc. can do.

The grooves are recessed from the surface, giving it a neat appearance.
