Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a pseudo-wooden fence installed on a sidewalk or in a park.

(Prior Art) Conventionally, sidewalk fences installed along sidewalks are generally constructed by installing horizontal steel pipes, steel plate rails, ropes, etc. between steel pipe supports. Such sidewalk fences do not match the surrounding environment, especially when installed in mountainous areas, and are not desirable in terms of environmental conservation.

On the other hand, as pseudo-wooden fences installed in parks and the like, for example, pseudo-wooden fences as shown in Publications No. 58-47158 and No. 60-9341 are known. These artificial wooden fences all have a steel plate or steel pipe as the core material, a coating layer made of plastic etc. is provided on the surface, and the surface of the coating layer is made of artificial wood with an uneven pattern similar to wood skin. A crosspiece is formed.

However, in conventional artificial wood supports and wooden crosspieces, the coating layer is easily peeled off because the surface of the core material remains flat and the coating layer is formed on the surface.
In addition, in order to form a wood grain-like uneven pattern on the surface of this coating layer, it is necessary to form the coating layer quite thickly, and a mold is required to form such a thick coating layer and uneven pattern. However, the molding equipment becomes large and the equipment costs are very high, and the length dimensions of the fake wood supports and the fake wood beams are inevitably limited. Furthermore, conventional faux wood fences have a structure in which radial holes are provided in the covering layer and core material of the faux wood posts, the tips of the faux wood beams are fitted into these holes, and the two are connected using connection bolts, etc. Therefore, the fake wood support cannot be erected on the ground or the like until after the artificial wood support is connected to the artificial wood support, resulting in problems such as very poor workability.

(Purpose of the invention) The present invention was made to solve these problems, and it is possible to easily form pseudo-wood posts and wooden beams of desired length with a simple device, improving mass productivity. To provide a pseudo-wooden fence that can significantly reduce costs, and even after the pseudo-wooden posts have been erected, allows easy connection of pseudo-wooden beams between the pseudo-wooden posts and improves work efficiency during assembly. It is.

(Structure of the invention) In the present invention, a pseudo-wood support is formed by applying a wood texture pattern and color to the surface of a metal tube, a bracket having a hole for connecting the fake wood is protruded from the surface of the pseudo-wood support, and , a pseudo-wood beam is formed by applying a wood texture pattern and color to the surface of a metal tube.
The end of this artificial wooden beam is formed in a shape that follows the surface of the artificial wooden support, and a connecting pin that engages with the beam connecting hole of the bracket is provided on the inner surface of the upper part of the peripheral wall inward from this end in the radial direction. At the same time, a notch is provided in the lower part of the peripheral wall at the same end to allow the insertion of the bracket, and the bracket is inserted into the end of the fake wooden beam, and the connecting pin is inserted into the connecting hole of the bracket. It is characterized in that the pseudo-wood support and the pseudo-wood crosspiece are connected by being engaged with each other.

(Example) In FIGS. 1 and 2, 1 is a fake wooden support, 2 is a fake wooden beam, 3 is a bracket, 4 is a mounting bolt for the bracket 3, and 5 is a connecting pin.

The fake tree support 1 is a metal pipe 1 such as a steel pipe or aluminum pipe.
Forming a large number of wood grain-like uneven patterns 12 on the surface of 1,
Furthermore, the surface is painted a wood skin color (mainly brown). 13 is a coating film.

The pseudo-wooden support 1 is manufactured using, for example, an apparatus shown in FIGS. 6 and 7. This device has two rollers 6, 7 arranged at the bottom, both rollers 6,
One roller 8 is disposed above between the rollers 7 and 7, and each of the rollers 6 to 8 has a substantially drum-shaped cross section, and has a large number of protrusions 61 on its surface for forming a wood texture pattern. 71 and 81 are discontinuously protruded. Note that the lower rollers 6 and 7 are provided to rotate at fixed positions via shafts 62 and 72 with respect to a mount (not shown), and the upper roller 8 is provided with a shaft 82 and a movable bearing (not shown) relative to the mount. It is provided so as to be rotatable and changeable in position in the vertical direction. Further, a plurality of idle rollers are provided at predetermined intervals in the feeding direction of the tube 11 as required.

The above apparatus generally uses an existing steel pipe rolling or shaping apparatus, and the projections 61, 71, 81 are provided on the surfaces of the rollers 6, 7, 8 of the apparatus by, for example, overlaying by welding. In this way, existing equipment only needs to be slightly improved, and equipment costs can be reduced.

A metal tube 11 such as a steel tube or an aluminum tube is supplied between the upper roller 8 and the lower rollers 6 and 7 to the above device, and the tube 11 is pulled out by, for example, a well-known pulling device (not shown). As a result, a large number of wood grain-like uneven patterns 12 are formed on the surface of the tube 11 by the protrusions 61, 71, 81 of the rollers 6, 7, 8. In this way, the tube 11 is connected to each roller 6, 7,
A wood texture pattern 12 can be easily formed on the surface of the tube by simply passing the tube through the tubes 8, and even long tubes 11 can be connected and formed.

After that, the tube 1 having the above-mentioned wood texture uneven pattern 12 is
Paint the surface of 1 a wood skin color (mainly brown). During this painting, a large number of discontinuous wood grain-like uneven patterns 12 are directly formed on the surface of the tube 11, so the paint has good adhesion, the paint film 13 is hard to peel off, and durability is improved. Therefore, it is sufficient to apply a coating using a known coating method using a known coating method, but in particular, after pretreatment, adding an extender such as cement or gypsum and a hardening agent to the acrylic or epoxy paint in the form of a powder. If a method of topcoating with a synthetic paint made by mixing with Overall wood texture uneven pattern 1
By the synergistic effect of 2 and the fine unevenness pattern on the surface, it is possible to manufacture a fake wood support 1 that is closer to natural wood, and the commercial value can be increased. It goes without saying that the above-mentioned coating may be applied in three or more layers, such as an undercoat, an intermediate coat, and a topcoat.

A plurality of pseudo-wood posts 1 configured as described above are erected on the ground or the like at predetermined intervals. A cover 14 is fixed to the upper end of each pseudo-wood support 1 by welding or the like, and an annual ring-like pattern 15 is formed on the surface of the cover 14, and a radial pattern is attached to the installation position of each pseudo-wood support 1. Penetrating bolt insertion hole 16
will be provided.

The bracket 3 includes an arcuate mounting portion 31 along the surface of the pseudo-wood support 1 and a cylindrical connecting portion 33 having a vertical connection hole 32, and a mounting bolt 4.
It is removably protruded from the surface of the artificial wood support 1 via a nut 41. The bracket 3 may be fixed to the surface of the pseudo-wood support 1 by welding.

On the other hand, the pseudo-wood support material 2 is produced by forming a large number of wood-like uneven patterns 22 on the surface of a metal pipe 21 such as a steel pipe or aluminum pipe by the same method as the above-mentioned pseudo-wood support support 1, and further changing the surface to a wood skin color (mainly brownish). ). 23 is a coating film.

This artificial wooden support 2 is formed to have a length corresponding to the interval between the artificial wooden supports 1, and has both ends 24 cut into an arc shape corresponding to the circumferential surface of the artificial wooden support 1, and near both ends, the inner surface of the upper part of the peripheral wall. A connecting pin 5 that engages with a connecting hole 32 of the bracket 3 is fixed and protruded in the radial direction by welding or the like, and a notch 25 corresponding to the bracket 3 is provided in the lower part of the peripheral wall. The connecting pin 5 is not limited to a cylindrical shape as shown in the figure, but may be rod-shaped.

Then, by placing both ends of the fake wooden crosspiece 2 over the bracket 3 through the notches 25 and engaging the connecting pin 5 with the connecting hole 32 of the bracket 3, the bracket 3 is inserted into both ends of the fake wooden crosspiece 2.
Both ends of the artificial wooden beams 2 are connected to brackets 3 in a state where the artificial wooden beams are concealed, thereby constructing the artificial wooden beams 2 between the respective artificial wooden supports 1, and assembling a predetermined artificial wooden fence.

In this case, it is possible to simply insert the connecting pin 5 whose tip is tapered into the connecting hole 32 as shown in FIG. A stopper step 51 is formed on the outer periphery near the tip, and a plurality of slits 52 are provided at the tip.
After the connecting pin 5 is inserted into the connecting hole 32, the retaining step 52 is elastically engaged with the lower end opening of the connecting hole 32. By preventing the pin 5 from coming off, the connected state can be more firmly maintained.

By providing the notches 25 in advance at the lower part of the peripheral wall at both ends of the artificial wooden support 2 as described above, even after the artificial wooden supports 1 are erected at predetermined intervals, the connecting pins 5 can be inserted into the connecting holes 32. Just put it in, you can make fake wood crosspiece 2.
can be easily connected between one pseudo-wooden support, greatly improving work efficiency.

In addition, after connection, the bracket 3 and connection pin 5
are completely hidden within the artificial wooden fence 2, and the heads of pins and bolts do not protrude from the surface of the artificial wooden fence 2, so that the appearance of the artificial wooden fence is not impaired.

(Effects of the invention) As described above, the artificial wooden fence of the invention is made by forming a large number of uneven wood texture patterns directly on the surface of a metal pipe, and using artificial wooden supports and wooden crosspieces that are colored with wood skin color on the surface. This structure allows for the easy formation of artificial wooden supports and artificial wooden crosspieces using existing pipe rolling or shaping equipment, which reduces equipment costs, and allows for easy continuous forming of long objects. It is possible to improve mass productivity and significantly reduce costs. In addition, since a large number of wood grain-like uneven patterns are formed directly on the surface of the metal tube, when painting that surface, the paint has better adhesion, and compared to the case where a conventional plastic coating layer is provided, the paint film is more stable. It can be made thinner, and the durability can be improved without the paint peeling off or cracking.

Moreover, since the brackets are protruding from the surface of the artificial wooden support, the notches are provided at both ends of the artificial wooden support, and the connecting pins are provided inside the brackets, the abovementioned notches can be removed even after the artificial wooden support has been erected. By using this method, both ends of the fake wooden beams can be covered with brackets to easily connect the fake wooden beams between the fake wooden supports, and the workability when assembling the fake wooden beams can be greatly improved, and the fake wooden beams can be replaced. It has many practical effects, such as being easy to use.
