Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to fences installed in residential gardens, parks, etc., and particularly relates to a grid fence connection device.

(Prior Art) Conventionally, as a connection device for a grid fence, it is known that separate supports are erected on the ground at appropriate intervals, and a grid fence is erected and connected to these. Furthermore, Japanese Utility Model Application No. 57-144861 shows a wire mesh machine in which a column part and a rope part are integrated.

However, when separate columns are used, the continuity of the grid design is interrupted at the column, which impairs the sense of lightness, and there is a limit to speeding up the construction work. Ta.

On the other hand, the latter has an integral pillar part, but is formed by bending one end of the pillar part or wire mesh into a cylindrical shape, which requires several bending steps to form the cylindrical shape, resulting in high cost. In addition, in terms of workability in connection construction, etc., the pillar part or one end only had a one-legged shape, which made it difficult to balance when carrying or standing up. Furthermore, in the illustrated example in the same issue, it appears that the ends of the horizontal strands of wire mesh are inserted into the cylindrical columns of the adjacent wire mesh, and then welded one by one to the vertical strands of the columns on-site, so quick construction is expected. I couldn't come.

(Object of the Invention) The present invention was made in view of the problems of the conventional grid fence described above, and it is possible to maintain the continuity of the design and reduce manufacturing costs, and is also convenient for handling in terms of logistics and cargo handling and on-site construction. Another object of the present invention is to provide a lit fence connecting device that allows quick work.

(Structure of the Invention) In accordance with the above-mentioned object, the present invention has integrated support sections at both left and right ends of a grid fence, where both branch sections are not cylindrical, and for example, one end side support section is one side support section. While forming a bulge in the opening, the other end side support portions are made flush with the plane of the fence, and the adjacent support portions of the connecting grid fence are overlaid and fixed to these non-cylindrical left and right end support posts. The overlapping part is formed as a cylindrical integral support, that is, in the present invention, both left and right ends of a grid fence formed by welding a large number of thin metal rods arranged in vertical and horizontal grids extend downward. In addition to forming an integral support section, one end side support section forms a bulge with an opening on one side that is curved or bent in a concave shape in the front and back direction, and the other end side support section forms a bulge on the side opposite to or opposite to the plane of the fence. A grid characterized in that similar bulging portions are formed, and adjacent support portions of the connecting grid fence are bonded and fixed to these left and right end supports 4'F, so that the overlapping portion becomes a cylindrical integral support. The gist is a fence connecting device.

The present invention will be described below with reference to drawings showing embodiments.
1 in the figure is a grid fence equipped with a connecting device 2 of the present invention, and the grid fence 1 is made by arranging and welding a large number of thin steel rods in vertical and horizontal grids, and then drawing and bending them with a press. It is formed by applying paint. In addition, the dimensions can be standardized in various ways, with the left and right width set at about 2 meters as a standard, and the height set at about 2 meters as the upper limit, and the following dimensions are prepared. Of course, a large number of such fences are connected and installed at the boundaries of houses, etc.

The connecting device N2 of the present invention forms integral support portions 3 and 4 at both left and right ends of the grid fence l, and also secures the adjacent support portions 3' or 4° of the connected grid fence 1' to these in a superimposed and fixed manner. As a result, the overlapping portion 6 becomes a cylindrical integral support. (Refer to Figure 1. To check whether there are any differences between the two fences, a dash is added to each part number for the sake of explanation.) The left and right support sections 3 and 4 are both of the vertical bars at both left and right ends of the grid fence l. By making some of the pillars longer than the others, both ends extend downward to form an integrated support pillar. Here, in the figure, 11... are the vertical bars of the grid fence, 12... are the same vertical bars or especially the long vertical bars mentioned above, 13... are the same horizontal bars, 14...・indicates either a horizontal bar or a short horizontal bar, which will be described later. Therefore, the first
In the example shown in the figure and Fig. 2, the long vertical bar 12 is placed at the left end with three pieces of wood.
On the other hand, the right end shows two of these arranged (
Usually, about 2 to 6 long vertical bars are arranged at each end).

One end of this support 3.4 forms a bulge with an opening on one side that is curved or bent in a concave shape in the front-rear direction. is curved into a semicircular or semielliptical concave shape on the rear side of the fence, and an opening (opening 31) is formed on the front side to form a bulge 32. On the other hand, the right end support portion 4 in the illustrated example is formed flush with the plane of the fence.

Note that the widths of both the left and right branch sections 3.4 are the same. In addition, short horizontal bars 14 are welded to the downward extensions of both branch offices in the same way as the other horizontal bars.This ensures the strength of the columns and prevents them from being removed from the concrete fixed part This is for the purpose of adjusting the level when fixing the pillars by arranging both the pillars equally and at appropriate heights. In the illustrated example, the marks and ground levels are determined in consideration of fixing strength and appearance, and the third short horizontal bar from the bottom of both the left and right support columns 3.4 is arranged accordingly. Therefore, during construction, all you have to do is adjust the height of the short horizontal bars to the ground level, temporarily tighten the fence, and then fill in concrete. However, the lengths of the left and right struts 3.4 themselves are not necessarily equal; in the illustrated example, the downward extending portion of the right strut 4 is slightly shorter than that on the left, and this is due to the effect of the hook 33, which will be described later. It's for a reason.

In this way, the grid fence 1 formed with the integral pillar parts 3゜4 on both the left and right ends can be constructed by connecting similar fences next to it (connecting grid fences 1''), or by sequentially installing them in parallel or here. Adjacent support sections 4'' and 3.degree. of the connected grid fence 1.degree. are superimposed and fixed to the left and right end support sections 3 and 4, respectively, and as a result, the overlapping section 6 becomes a cylindrical integral support.

That is, FIG. 1 shows a state in which two fences are connected, and the left end support 3 (
From the opening side, the right end support 4' (flush with the fence plane) of the connecting grid fence 1' (left side in the figure) is overlapped and fixed to the concave shape (side opening) so as to close the opening. The metal fittings 5 are used to secure both fences to each other,
Although not shown, a large number of fences are similarly connected below. As a result of the overlapping of the support portions of both fences, the overlapping portion 6 is formed as a cylindrical integral support.

As mentioned above, the left end support 3 of the lid fence l is curved and bulged in a concave shape on the rear side of the fence, while the right end support 4 of the connecting fence l° overlapped with this is formed with a fence plane. Since they are flush, the cylindrical integral support is hardly noticeable when viewed from the front side of the fence, and the design on the front side of the fence, in which a large number of them are connected, is continuous horizontally.

To add some additional information, the means for fixing the adjacent column 3.4' are as follows:
As shown in Figure 5, the horizontal bar 1 at the top of the grid fence l
3.13 and connecting grid fence 1' upper horizontal bar 13'
, 13' are fixedly connected to each other by means of a fixed portion and a fixture 5.

That is, in the figure, 51 is the stainless steel bottom plate of the same metal fitting, and 52 is the bottom plate made of stainless steel plate.
．． 52 is a holding plate of the same quality, 53.53 is a screw, the bottom plate and the holding plate are press-formed with recessed grooves that match the cross section of the fence rod, and the bottom plate has screw holes and the holding plate has screw holes in the horizontal direction. A long hole is drilled through and a screw is passed through the fence horizontal bar 1.
3, 13. 13° and 13' are sandwiched together and both plates are fixed with screws. In addition, 54.54 in the figure is a protrusion that is cut up from the bottom plate 51 and inserted between both fences, which absorbs irregularities such as irregularities at the adjacent ends of both fences and makes the connection reliably strong. .

In the example shown in Fig. 5, the fixed part is slightly shifted to the right from the overlapping part of the support parts 3 and 4, but in this way, the fixed part does not necessarily stick to each other only in the overlapping range of the support parts. do not have. Further, although not shown, such fixing metal fittings 5 are similarly provided at the lower part of the fence, and if the strength is sufficient, both fences can be fixed at two places above and below. On the other hand, when the height of the fence is large, appropriate fixing fittings are provided at intermediate heights if necessary. Figure 6 shows an example of this, and whether the fixing parts etc. are slightly different (for example, overlapping fittings). It is basically the same as the above, except that the long vertical bars 12.12, 12°, and 12° are fixed instead of the horizontal bars of the support column, and that there is only one holding plate 52 (g?). It is. In addition, Fig. 5 and Fig. 6 are as follows.
Although the number of long vertical bars 12 in the support section 3 is different from Figure 1 (5 bars vs. 3 bars), there is basically no difference and this is an enlarged part of Figure 1. be. In addition, a steel plate can be used as another material for the fixing fitting 5. Furthermore, it is also possible to weld and secure key points of the overlapping portions of adjacent struts on-site without using a fixing member.

Next, the hook 33 in the figure is attached to the left support portion 3.
It is formed by bending the tip of a short horizontal bar 14 welded to the top of the bar upward. A horizontal bar 13 corresponding to the height of the adjacent grid fence 1' is hung on the hook 33 to prevent it from falling down and facilitate the connection work of the adjacent grid fence 1'. By adopting this hook 33,
The connection work can be done quickly by one person.

It should be noted that it was mentioned earlier that the short horizontal bars 14... are welded in advance to the downwardly extending portion of the column 13.4 and used for leveling during construction, etc. The reason why it is welded to the fence 4 in advance is because the upper integral edge part 34, which will be explained next, has been narrowed and bent on the two parts of the fence 4, so if a normal horizontal bar is extended this far, it will not be possible to bend it. This is because it is inconvenient.

Next, 34.35 in the figure indicates the upper and lower integrated edges, and the upper and lower parts of the fence 1 are pressed and bent by pressing to form a concave bulge on the front side of 111. This not only improves the strength of the fence, but also allows the torso edge portion 34 to have a handrail function.

Here, in the illustrated example, the upper and lower integrated edges 34, 35 are bulged out to the opposite side in the front and back direction (i.e., the front side of the fence) from the bulging left support portion 3, so that a large number of fences installed side by side When viewed from the front side, the design of the body edge is not cut by the pillars, and the continuity between the left and right sides is maintained, making it beautiful. Furthermore, if the upper and lower integral +1=1 edges are formed into a cylindrical shape, the strength can be further improved, although the number of bending steps must be increased. When such a cylindrical body edge portion is formed, the height of the strut portion (in the UA example, the left strut portion 3.3°) in which the bulge portion is formed, in particular, of the strut portions 3.4 is By stopping directly below the torso edge, the left and right sides of the old upper edge design can be fixed! I! The continuity is maintained and beautiful.

In addition, vertical and horizontal bars 11..., 12... of the fence.

As other materials for 13..., 14..., stainless steel rods may be used to enhance corrosion resistance.

In addition to the above-mentioned semicircle and semi-ellipse, a U-shape, 〉-shape, etc. can be adopted as the shape of the recess in the front-rear direction of the support column 3.4. Of course, only one end of the left and right end support sections 3.4 may be curved or bent in a concave shape in the front-rear direction, and the other end may be flush with the fence surface (as illustrated), or both may be concave. . In the latter case, each support post 3.4 is curved or bent in a concave shape on opposite sides in the rear direction of the fence to form a bulge of the (opposite) negative side opening. When connecting the connecting grid fences 1°, the openings are made to face each other and are overlapped to form a cylindrical integral internal support that bulges in both the front and rear directions of the fence.

Although the embodiments have been constructed as described above, it goes without saying that the present invention can be implemented in various ways as long as it does not violate the above-mentioned spirit, and is not limited to the embodiments described above.

(Effects of the Invention) Since the present invention is constructed as described above, it has the following effects.

That is, the grid fence connecting device of the present invention is made by extending both left and right ends of a grid fence formed by welding a large number of thin metal rods in a vertical and horizontal grid pattern downward to form an integral support section. Compared to conventional grid fence connection devices that use separate supports, the continuity of the grid design is uninterrupted, and the connection of homogeneous and integral cloud-shaped supports allows
The lightweight design that is a feature of grid fences can be arranged continuously without the pillars feeling uncomfortable.

In particular, among such integral support sections, one end side support section forms a bulge with an opening on one side that is curved or bent in a concave shape in the front-rear direction, and the other end side support section is flush with the plane of the fence or A similar bulge is formed on the opposite side, that is, both support columns are non-cylindrical, so it is possible to form this by -times of bending (squeezing with a press mold etc.), unlike the conventional cylindrical shape. Unlike struts, there is no need for multiple bending processes, and manufacturing costs can be significantly reduced.

Furthermore, when packing a fence, the support column formed by forming a bulge with an opening on one side that is curved or bent into a concave shape is not as bulky as a conventional cylindrical integral support. , the economy of transportation and inventory can be improved.

In addition, since such integral support sections are formed on both the left and right ends of the grid fence, it is easier to carry or stand up compared to the conventional one-leg structure in which a cylindrical integral support is formed only at one end. It has excellent left-right balance, making it convenient to handle in terms of logistics and cargo handling as well as on-site construction.

Furthermore, in the grid fence connection device of the present invention, the adjacent support sections of the connected grid fence are superimposed and fixed to the left and right end support sections, and the overlapping section becomes a cylindrical integral internal support, so that the connection support strength is higher than that of the conventional one. It is not inferior in any way to the cylindrical type, and in fact, the connection strength is improved and the connection work is made faster by the superposition and fixation of the support and adjacent support (instead of welding each horizontal bar one by one on site as shown in the published drawings). It is possible to expect something (not necessary).
