Description

[Detailed description of the invention] This invention relates to a metal fence, and in particular to a metal fence in which horizontal strips and horizontal lattices are arranged above and below to form a boundary surface. be.

Conventionally, in this type of fence, the strips have a uniform thickness over the entire width, and the thickness is usually smaller than the thickness of the lattice. Placed and fixed on the line.

Therefore, it is not easy to position and fix the strips and lattices of different thickness and thickness on vertical lines, and when the fence is completed, the strips and the lattice will be installed unevenly, which will spoil the appearance of the fence. was there.

This idea involves positioning the strips and the lattice on a common vertical plane in a fence in which the strips and the lattice are arranged to form an interface.
Another object of the present invention is to provide a metal fence that can be easily fixed, does not shift in position, and has excellent fixing strength and appearance.

Next, one embodiment of this invention will be described based on the drawings.

As an example of the metal base according to this invention is shown in FIG.
Between the left and right vertical bars 1 and 1, there is a horizontal bar 2...and a strip plate 3.
An assembly formed by arranging and fixing .
A cap 5 is fixed to the upper end of the 4.

All of these components are made of metal, preferably aluminum profiles.

Reference numeral B indicates a foundation, which is made of concrete, for example, and is formed with a length equal to the distance between adjacent columns.

As shown in FIG. 2, the left and right vertical bars 1 are formed of the same material, have a groove 6 in the center in the width direction, and have a groove 6 on both sides of the groove 6, which is bent in the opposite direction to the groove 6. It has curved locking edges 7,7.

The locking edges 7, 7 are projected from the bottom back surface of the groove 6 in the direction opposite to the opening direction of the groove, and are screwed from the bottom back surface of the groove 6 into the horizontal beam and the band plate as described later. The head of the screw is prevented from protruding outward beyond the locking edge 7.

Further, a plurality of thin notches are formed in the longitudinal direction on the back surface of the groove 6 to facilitate positioning of screws for fastening the vertical and horizontal beams and to prevent distortion of the groove 6.

The horizontal bar 2 is formed into a cylindrical shape, and its thickness 11 is approximately equal to the inner width 12 of the groove 6 of the vertical bar 1, so that the horizontal bar 2 is placed in the groove 6 of the vertical bar 1 without play. It can be fitted like this.

In the illustrated example, the horizontal bar is formed into a rhombus-shaped rectangular tube shape, and its thickness, that is, the diagonal line 11, is equal to the width 12 of the groove 6, and the horizontal bar is fitted into the groove 6 with its diagonal line in a horizontal state. It is now possible to match.

A screw hole 9 is formed on the inner surface of the horizontal crosspiece 2.

The band plate 3 is formed by integrally providing cylindrical parts 2' having the same shape as the horizontal bar 2 at both widthwise ends of a thin flat plate 10, and each cylindrical part has a thickness equal to the thickness 11 of the horizontal bar 2. have.

Each cylinder also has a screw hole 11 on its inner surface.

With the configuration of the horizontal bar 2 and the strip plate 3 described above, in order to form a boundary surface assembly together with the vertical bar 1, the longitudinal ends of the horizontal bar 2 are inserted into the grooves 6 on the opposing surfaces of the left and right vertical bars 1. and groove 6
A screw passing through the vertical bar from the bottom back side of the frame is screwed into the screw hole 9 of the horizontal bar to connect the vertical bar and the horizontal bar.

In the same way, the longitudinal end of the strip 3 is fitted into the groove 6, and the screws passing through the vertical bar are inserted into the screw holes 1 in the cylindrical portion of the strip.
1 to connect the vertical beam and the strip.

In this case, both the horizontal bars and the strips are fitted into the grooves 6 of the vertical bars so that there is no play in the width direction, making it easy and accurate to position the vertical bars in the width direction. , Nagata,
Screws can be inserted into screw holes accurately.

In the illustrated embodiment, two horizontal bars 2 and one strip plate 3 are alternately arranged at an appropriate interval from the foundation to the top in the longitudinal direction of the vertical bar 1, and each of the strip plates 3 is The flat plate 10 has a pattern of combinations of circular arcs punched out in the center in the longitudinal direction, providing a high degree of design effect.

Of course, this invention is not limited to the arrangement and pattern of the horizontal bars and strips as shown in the drawings, and the arrangement pattern and pattern of the horizontal bars 2 and strips 3 are arbitrary.

Then, as in the illustrated example, the thin rod-shaped horizontal beam 2 and the flat plate-shaped strip 3 are placed at appropriate intervals, and the strip 3 is adjusted to the appropriate height, taking into account the average height of a person. By arranging the fence, it is possible to install a fence that has an effective blindfold function and ventilation function, and has an excellent appearance in terms of design.

The boundary surface assembly formed by fitting and fixing a plurality of horizontal bars 2 and strips 3 to the vertical bars 1 and 1 in the above manner is assembled and stored in advance at a factory or business office, and can be easily assembled and stored at the time of fence installation. It can be transported to the site by truck.

Next, the support posts 4 are shaped members having a parallel cross-section, and the base edges of the four circumferences have the same shape so that the fence can be extended or expanded in the right angle direction.

The outward opening concave groove 12 at the base edge has an inner width m and a depth nl, which is approximately equal to the full width m2 of the vertical beam 1, and the unit is inserted in the longitudinal direction of the support 4 from the top. This prevents rattling when sliding together.

In addition, the depth nl of the groove 12 is the height n of the locking edge 7 of the vertical beam 1.
□, so when the assembly is fitted between the left and right supports, the support and vertical beam appear to be one body when viewed from the outside.

The central part of the inner surface of the base edge of the support column 4 has a thick wall part 13, which has a function of reinforcing the strength.

Kasagi 5 has three step-like roof panels that slope down on both sides, and two
A protruding edge 14a extending downward from the lower edge 14 of the roof plate of each step
, a horizontal edge 15 for attaching the cap, and this horizontal edge 1
Two hanging edges 16.16 extending longitudinally at the bottom of 5.
It consists of

The inner width W1 between these hanging edges 16, 16 is made slightly larger than the overall width W2 of the column 4, so that the cap 5 can be fitted to the upper end of the column 4.

An open space 18 is formed by the 1.2-tier roof 17, the projecting edge 14a, and the horizontal edge 15 on both sides, thereby preventing the bowstring from bending or twisting.

Further, a thick wall portion 19.19 is formed on the upper surface of the horizontal edge 15, and has a wall thickness sufficient to form a tapped hole into which a screw to be attached via a Kasagi mounting bracket 20 (described later) is screwed. have.

Further, screw holes 21, 21, 21 are formed at the top of the roof and at the lower ends of both sides for attaching Kasagi end caps (not shown) to the Kasagi end faces at the ends of the fence.

In addition, when connecting a plurality of caps 5, a thin plate-shaped seal made of plastic or rubber, for example, having the same shape as the outline of the end surface is attached to the hollow portion 18 in order to prevent rust on the cut end face of each caps. The end surface can be sealed by fitting or adhering.

The Kasagi mounting bracket 20 that fixes the Kasagi 5 to the support post 4 includes a long plate 23 in the form of a strip having a concave groove 22 formed in the longitudinal direction in the central part in the width direction, and a long plate 23 that is fixed on both sides of the central part in the longitudinal direction of the long plate 23. It consists of bent pieces 24 and 24 bent at right angles to the direction.

The outer width h1 of these bent pieces 24, 24 is made slightly smaller than the inner width h2 between the opposing edges of the support 4, and when the Kasagi mounting bracket 20 is pressed down from above to the upper end of the support, they fit together. A screw is screwed into the tapped hole 25, 25 from the outside through a hole (not shown) drilled in the support column 4.

Therefore, since the Kasagi 5 can be fitted to the upper end of the column to which the Kasagi mounting bracket 20 is attached as described above, the Kasagi 5 can be fitted into the hole 26.2 from the bottom.
6, the screw is inserted into the thick wall part 19.1 of the horizontal edge 15 of the cap 5.
By screwing into the threaded hole formed in 9, the cap 5 can be securely fixed to the support 4.

As described above, according to this invention, cylindrical portions having approximately the same thickness as the horizontal bars are provided at both ends in the width direction of the strip, and the cylindrical portions of the horizontal bars and the strip are provided on opposing surfaces of the left and right vertical bars. A groove with a width equal to the width of the horizontal frame is provided, and both longitudinal ends of the horizontal bar and the strip are fitted into this groove, and screws passing through the back of the vertical bar are inserted into the cylindrical portions of the horizontal bar and the strip. Since the assembly is constructed by inserting screws into screw holes formed on the sides, the first step is to position the horizontal beams and the strips on a common vertical plane between the opposing surfaces of the vertical beams. can be easily done, therefore, secondly,
It can be fixed accurately and reliably with screws, and thirdly, the arrangement pattern of the horizontal bars and strips can be determined arbitrarily, and,
Because the horizontal beams and strips are aligned, the appearance of the fence is also excellent.
