Description

[Detailed description of the invention] [Industrial application field] This invention is an aluminum alloy construction in which a large number of vertical bars are erected and fixed between horizontal bars, and is used for gates, fences, handrails, balconies, etc. Regarding partitions.

[Conventional technology]

In this type of partition, the upper and lower ends of the vertical bars are brought into contact with the fixing protrusions that are offset to one side of the front and back of the horizontal bars, and the vertical bars are fixed with rivets from the protrusions. One with a fixed crosspiece is known.

[The problem that the idea attempts to solve]

However, with this partition, the front and back sides are clearly visible at first glance because the fixing protrusion is offset to one side in the front and back, and the heads of the rivets are exposed to the protrusion. It will have a partition state,
It is unavoidable that the appearance, especially on the back side, will be impaired. Therefore, for example, when a fence with this configuration is used to demarcate a boundary with a neighboring property, there is a problem in that one of the neighboring houses has to have an appearance on the back side.

In addition, this partition structure requires both the process of molding through holes for fixing rivets on both the fixing protrusions and the vertical bars, and a separate manual riveting process. Therefore, there are problems in that the assembly work is complicated and it is difficult to automate the assembly.

The present invention was developed in view of these problems, and its purpose is to create an aluminum alloy construction material that does not distinguish between the front and back sides as a partition, has a good appearance, and is suitable for automated assembly. It is there to provide a partition.

[Means to solve the problem]

The present invention consists of opposing protrusions that are integrally provided in the middle position of the opposing surfaces of opposing parallel horizontal bars, and a rectangular fitting that is partitioned by a pair of grooves at predetermined intervals in the longitudinal direction of the opposing protrusions. A projecting piece, a vertical bar formed by fitting the fitting projecting piece into a hollow part at the upper and lower ends and sandwiching opposing walls defining the hollow part between a pair of grooves, and opposing faces of the vertical bar. An aluminum alloy architectural partition comprising a fitting hole provided in a wall and a bulging protrusion formed by crushing the cut edge of the opposing protrusion that is fixed in the fitting hole. This is relevant and serves as the gist.

[Effect]

In the case of the present invention, the vertical bars are shaped like horse-riders on the opposing protrusions of the horizontal bars, and are clamped by the cut grooves, fitted with the fitting protrusions, and locked with the bulging protrusions in the fitting holes. As a result, it is automatically firmly erected and fixed between the horizontal beams.

〔Example〕

Hereinafter, the present invention will be further explained with reference to an embodiment in which the present invention is applied to a fence made of aluminum alloy. Reference numeral 1 is a fence, and this fence 1 includes opposing parallel horizontal bars 3, which are horizontally supported on left and right columns 2, 2, A large number of small vertical bars 4 are erected and fixed at predetermined intervals between 3 and 3.

Each of the horizontal beams 3 has an integral opposing protrusion 5 erected in the center in the front-rear direction of the intermediate position of the opposing surface.

The opposing protrusions 5 are provided with a pair of notches 6, 6 at predetermined intervals in the longitudinal direction, corresponding to the upright positions of the vertical bars 4... The protruding piece 7 is provided. In this example, the kerf 6 has a width corresponding to the thickness of the vertical bar 4, and the depth of the cut is approximately 1/2 of the upright height of the opposed ridge 5.

The small vertical bars 4 are made of substantially rectangular hollow pipe materials, and the opposing walls 9, 9 that define the hollow portions at the upper and lower ends thereof are similarly provided with the opposing protrusions 5, 5. The cut grooves 10, 10 have a cutting depth of approximately 1/2 of the height of the die. Fitting holes 11, 11, which are made transparent through processing, are provided.

In this example, the horizontal bar 3 and the vertical bar 4 have a pair of kerfs 6, 6 in the opposing protrusion 5 and kerfs 10, 10 in the opposing walls 9, 9 that are fitted into each other. The kerfs 6, 6 have opposing walls 9, 9 on the extension line of the kerf grooves 10, 10, and the kerfs 10, 10 have the remaining portions of the opposing protrusions 5 on the extension line of the kerfs 6, 6. The fitting protrusions 7 are fitted into the hollow portions of the small vertical beams 4. Furthermore, at this time, by crushing the upper edge of the opposing protrusion 5 near each of the kerfs 6, the kerfs 6...
A bulging protrusion 8 that bulges inward is locked into each fitting hole 11 of the small vertical crosspiece 4, so that the small vertical crosspiece 4 can be riveted against the horizontal crosspieces 3, 3. It is erected and fixed without using any tools.

In addition, numeral 12 in the figure is a cap that closes off the upper end of the vertical frame 2.

In order to assemble the fence 1 according to this example, for example, by automatic assembly, the horizontal bars 3,
3, by arranging the small vertical bars 4 at right angles to these horizontal bars and pressing them in opposite directions from the horizontal bars 3, 3 side, the kerfs 6, 6, 1 are formed.
0 and 10, and the opposing protrusions 5 are partially crushed at predetermined positions to form respective bulging protrusions 8, which are inserted into the fitting holes 11. The support 2 may be fixed after that.

To lock the bulging protrusion 8, pressurize the opposite protrusion 5 from both front and back sides of a predetermined position using a mold with a reduced diameter tip, and press the flesh of the opposed protrusion 5 into the fitting hole. It is convenient to allow the liquid to escape toward the outside of the edge including the side where 11 is located.

At this time, each of the molds on both the front and rear sides is formed into a U-shape in plan cut out according to the width of the small vertical beam 4, and a pair of protruding left and right tips are each provided with a pressure end with a reduced diameter. If so, both of the vertical bars 4 can be bulged and locked into the respective fitting holes 11, 11 of the opposing walls 9, 9 with one press, which is efficient.

Although the embodiment is constructed as described above, the specific shapes and structures of the horizontal bars, vertical bars, opposing protrusions, fitting protrusions, bulging protrusions, and fitting holes, their relationships, assembly means, and their The steps and the like can be changed in various ways as long as they do not go against the gist of the invention, and there is no need to limit them to what has been shown and described.

[Effect of idea]

Since the present invention has the configuration shown in the gist of the invention, a large number of vertical bars can be erected and fixed between opposing parallel horizontal bars without using rivets or screws that spoil the appearance. In addition to this, the ends of each vertical bar are arranged in a horse-riding shape on the opposing protrusions in the middle of the opposing faces of the horizontal bars.As a result, there is no distinction between the front and back, and both sides have a good appearance. Aluminum alloy architectural partitions can be provided for various purposes.

In addition, when fixing the vertical bars upright, it is sufficient to perform mechanical processing on the horizontal bars and vertical bars, but since there is no structure that requires manual labor, it is possible to automate the assembly. It is considered suitable.

Furthermore, as described in the operation section, since the vertical bars can be firmly fixed to the horizontal bars, it is possible to obtain an aluminum alloy architectural partition that has excellent strength and durability as a whole.
