1 is a front view of an example of a fence made of synthetic resin containing wood powder according to the present invention. This fence made of synthetic resin containing wood powder has a plurality of panel bodies 2 arranged between columns 1 standing upright on the ground at predetermined intervals.

[0008] post 1 has a metal (e.g., aluminum) is formed in a square tubular, below the sides the panel body 2
A support fitting 4 that engages with the lower end of the vertical bar 3 and supports the panel body 2 (the vertical bar 3) from below is screwed.

The panel body 2 forms a rectangular frame 7 by framing the upper and lower furring edges 5, 6 and the vertical bars 3 on both left and right sides, and a horizontal lattice forming a blind panel inside the rectangular frame 7. As shown in FIGS. 2 and 3, the upper furring strip 5 and the lower furring strip 6 are each formed into a substantially C-shaped cross section, and the upper furring strip 5 is located downward and the lower furring strip 5 is formed. 6 is open upwards. In addition, core materials 11 and 12 made of extruded aluminum are inserted into the upper furring strip 5 and the lower furring strip 6, respectively.
A screw hole 10 is formed in each of 1 and 12. The core materials 11 and 12 are provided with the concave grooves 13 and 14, respectively. A saw-toothed concavo-convex portion 15 is formed on the inner side surfaces of the concave grooves 13 and 14.

The vertical crosspiece 3 is also basically C-shaped in cross section, and has a concave groove 16 formed on the back surface thereof. A metal core material 17 such as aluminum is provided along the inner surface. On the inner surface of the concave groove 16, the saw-toothed concavo-convex portion 15 is formed.

The vertical rails 3 on both sides are arranged so that the concave grooves 16 face each other, and the screws 18 inserted from the core material 17 are attached to the furring strip 5,
By fixing to the screw holes 10 of the core members 11 and 12 of 6, the rectangular frame 7 in which the upper furring strip 5 and the lower furring strip 6 are connected to the left and right vertical bars 3 is formed. Recessed grooves 13, 14, 16 are formed on the inner peripheral surface.

Next, as shown in FIG. 3, the horizontal lattice 8 is a hollow body having a parallelogram in cross section, and a core material 20 made of an extruded shape material such as aluminum is inserted into the hollow portion 19 and is formed in the center thereof. Has a screw hole 21 formed therein. The horizontal lattice 8 is press-fitted into the groove 13 of the vertical bar 3 of the rectangular frame, and is fixed by fixing the screw 22 inserted from the outside of the vertical bar 3 to the screw hole 21 of the core member 20. . A vertical grid may be used instead of the horizontal grid.

Panel body 2 formed as described above
When attaching the to the columns 1 standing upright at regular intervals, fit the openings 23 of the vertical bars 3 to the upper ends of the columns 1,
Further, the lower end of the vertical rail 3 is lowered along the column 1 until it hits the support fitting 4 fixed to the column 1. When the panel body 2 is supported by the support fitting 4, by covering the upper end of the vertical bar 3 with a cap 26 from above the pillar 1, and attaching a mounting piece 27 formed on the cap 26 to the pillar 1 by screwing,
The panel body 2 may be fixed to the column 1 by sandwiching the panel body 2 from above and below with the support fitting 4 and the cap 26.

In the groove 13 of the vertical bar 3, a serrated uneven portion 15 is formed.
Therefore, when the end portion of the horizontal lattice 8 is press-fitted, the uneven portion 15 bites on the side surface thereof, and there is no rattling or noise even if wind pressure is applied.

Further, since the metal support 1 is covered by the vertical bars 3 of the two adjacent panel bodies 2, it is not exposed to the outside and the appearance as a wooden fence is not impaired.

By the way, the vertical crosspiece 3, the furring strips 5 and 6, and the horizontal grid 8 are formed of synthetic resin mixed with wood powder. Since the wood powder is a powder of natural wood, it is possible to give a wood grain pattern to the wood powder by a special treatment during extrusion molding. Further, since wood powder diffusely reflects light, it does not have a feeling of light as compared with a metal surface coated with paint or printed. Therefore, the overall texture and texture are almost the same as those of natural wood,
The appearance of the fence composed of 5, 6 and 8 is so realistic that it can be mistaken for natural wood.

Further, since the above-mentioned constituent members are manufactured by extrusion molding, the quality is stable with the same shape and size, and mass production is possible at low cost. Will be easier.

Further, since the panel body 2 is made of synthetic resin, it does not cause warping or cracking due to aging as much as actual wood does, and it also facilitates fuzzing and fuzzing on the surface like wood. There is no need for maintenance such as brushing or painting regularly.

Next, FIG. 4 shows an example in which the lattice is a cross lattice, and the vertical crosspieces 3 and the furring strips 5 and 6 are the same as in the example of FIG. The panel body 2 is formed by intersecting grids 28a and 28b at a predetermined interval, and is provided with a core material 30 made of a hard synthetic resin in a hollow portion as shown in FIGS. Two
The crossing surfaces 8a and 28b (all or a part thereof) may be bonded with an adhesive, and the grooves 28a and 28b of the vertical bars 3 and the core members of the furring strips 5 and 6 in a state where the end portions of the grids 28a and 28b are superposed. 1
It is configured to be press-fitted into the concave grooves 13 and 14 formed in the concave grooves 1 and 12 and to be pressed into contact with the saw-toothed concavo-convex portion 15 formed in the concave grooves 13, 14 and 16.

A metal receiving plate 31 for receiving the end face of the furring strip is provided at the upper and lower portions of the vertical rail. Although it is not provided along the entire inner length of the vertical crosspiece 3, the vertical crosspiece 3 can be supported with sufficiently high strength because the support column 1 supporting the vertical crosspiece 3 is made of metal having high strength. it can.

[0021]

According to the first aspect of the present invention, the vertical rail, the furring strip and the horizontal lattice are formed of synthetic resin mixed with wood powder. Since the wood powder is a powder of natural wood, it is possible to give a wood grain pattern to the wood powder by a special treatment during extrusion molding. Further, since wood powder diffusely reflects light, it does not have a feeling of light as compared with a metal surface coated with paint or printed. Therefore, the texture and texture of the whole are almost the same as those of natural wood, and the appearance of the fence made of the above-mentioned constituent members is confused with that of natural wood.

Further, since the above-mentioned constituent members are manufactured by extrusion molding, the quality is stable with the same shape and the same size, and the panel body can be manufactured in an integrated manner in the factory, and the production efficiency can be improved. it can.

Further, since the panel body is made of synthetic resin, it does not warp or crack due to aging as much as actual wood does, and moreover, it does not flake the surface or fuzz like wood. There is no need for maintenance such as brushing or painting regularly.

In addition, since the saw-toothed concavo-convex portion is formed on the inner wall of the metal concave groove, when the end portion of the synthetic resin grade containing wood powder is press-fitted into the concave groove, this end portion is pressed. Since the concave and convex portions of the concave groove are tightly pressure-bonded to each other, the grid does not rattle in the rectangular frame after construction, and noise is not generated even when a strong wind pressure is applied.

According to the second aspect of the present invention, since the lattice is a vertical lattice or a horizontal lattice and the screw holes are formed along the longitudinal direction of the core material, the screw inserted from the outside of the vertical bar is formed. The lattice can be firmly fixed by fixing it to the screw hole of the core material.
