Description

[Detailed Description of the Invention] This invention relates to a fence mounting device.

The conventional fence mounting device of Fuens is the second
As shown in the figure, when a rectangular cylindrical rod 13 is installed vertically in parallel between every 12 spaces of the trunk rims, which are stretched in parallel between the upper and lower positions between the pillars (not shown),
Rivets 16, tapping screws 17, etc. were used. Therefore, a mounting hole 14 for inserting a rivet 16 or a tapping screw 17, etc., is provided in advance on the edge surface 12a, which is an extension of the front surface of the furring rim 12.
Further, it was necessary to carry out a preliminary work in which similar mounting holes 15 were formed through the surface portions of the mid-piece 13 corresponding to these positions. Therefore, when manufacturing the fence, the number of steps is large and the cost is high.In addition, when it rains, water intrudes through the mounting holes 14 and 15, causing damage to the furring 12.
There were various problems such as corrosion of the fence and the mid-edge 13, which shortened the durable life of the fence.

This idea was devised to solve the above problems, and its purpose was to simultaneously form the connecting parts for both sides when forming the rim and the middle crosspiece, thereby making it easier to make holes, etc. To provide a fence mounting device that can reduce costs by eliminating the need for preparatory work, and can also eliminate water intrusion into the interior and extend its durable life.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

First, to explain the structure, as shown in FIGS. 1 and 3, L-shaped support fittings 10 are installed at upper and lower positions between columns 2 that are erected at intervals on a foundation 1 made of lightweight blocks, concrete, etc. Using the presser metal fitting 11, the following body rim 3 is fixed in parallel with the symmetrical arrangement of the upper and lower parts.

This rim 3 is made by extrusion molding of aluminum or the like.
A vertical surface portion 4 of a predetermined length is provided below the outer central band of the inverted convex-shaped hollow cross member to protrude parallel to the longitudinal direction.
At each position where this vertical surface portion 4 is to be connected to a middle crosspiece 7, which will be described later, there are two cut grooves 5, 5 parallel to the vertical direction that can be fitted to the left and right vertical surfaces of the middle crosspiece 7. It is formed in the shape of Further, at a mid-height position on the front and rear surfaces of the vertical surface portion 4, horizontal grooves 6, 6 in the form of bands having a width and depth that enable a pushing operation to be described later from the front and rear directions are perpendicular to the respective cut grooves 5, 5. It is formed parallel to the longitudinal direction.

Further, the middle sill 7 attached between the upper and lower furring edges 3 according to this embodiment is formed by extrusion molding of aluminum or the like as described above, as described above. In other words, as clearly shown in FIG. 3, the hollow vertical member 7 is a rectangular hollow vertical member whose cross section is close to the width of the bottom of the hollow cross member 3, and the intermediate band on the left and right longitudinal surfaces thereof has a peripheral member. A pair of vertical pieces 8 are vertically parallel to each other and have a width sufficient to fit into the vertical surface portion 4 of 3 and to shield the front and rear horizontal grooves 6, 6 adjacent to the cut grooves 5, 5. A lateral groove 9 is formed between each of the vertical pieces 8 in a manner parallel to the longitudinal direction, into which the vertical surface portion 4 of the furring 3 can be fitted.

With the above configuration, when installing the middle support 7 in an upright manner between the upper and lower body edges 3, first use the supporting metal fittings 10 at the lower part between the pillars 2, and attach the body frame 3 according to the above to the third
It is fixed in an inverted manner from that shown in the figure, that is, in a manner in which the vertical surface portion 4 is located on the convex-shaped hollow cross member. Then, the lower ends of the middle beams 7 are inserted into the left and right end surfaces of the long hollow vertical members at each position of the cut grooves 5, 5 of the lower body rim 3, and are formed between the vertical pieces 8 on both sides. The vertical groove 9 is
They are erected one after another so as to fit into the vertical surface portions 4 of the furring 3 on each side. Next, each mid-section 7 according to this aspect
As shown in FIG. 3, at the head position of After positioning the vertical surface portion 4 corresponding to the position so as to be inserted into the vertical groove 9 of the middle beam 7 on each side, the upper body rim 3 in this state is attached to the support column 2 using an L-shaped holding metal fitting 11. sticks to.

Each of the central rods 7 erected in this manner is inserted into the left and right vertical pieces 8 into which the vertical surface portions 4 of the body rim 3 are fitted, from the outside at positions that match the front and rear horizontal grooves 6, 6. When a pushing operation is applied in the direction of the arrow as shown in FIG.
Since front and rear lateral grooves 6, 6 are present inside, the front and rear vertical pieces 8 on each side are deformed into a concave shape as they face the respective lateral grooves 6, 6. That is, since a convex shape is formed on the inner surface of each vertical piece 8 by the above-described pushing operation, this convex body B fits into the front and rear horizontal grooves 6, 6 of the vertical surface portion 4. . Therefore, each core 7 can be easily, reliably, and quickly attached to the body rim 3 at each position without requiring any fastening parts such as rivets or tapping screws.

Furthermore, as described above, when attaching each of the cores 7 to the body rim 3, fastening parts such as rivets and tapping screws are not used as described above, so that rainwater is reliably prevented from penetrating into the hollow interiors of the body rim 3 and the body 7. It can be prevented. Therefore, there is an advantage that corrosion of the members due to infiltration of rainwater is completely eliminated.

Furthermore, since both the above-mentioned furring 3 and the middle rim 7 are extrusion molded products made of aluminum or the like, the workability is extremely good. Therefore, the cut grooves 5, 5, which serve as the joining portions on each side, the front and rear horizontal grooves 6, 6, the vertical piece 8 with the vertical groove 9, etc. can be smoothly and easily formed at the same time.

As explained above, in this invention, when forming the main part of the fence, ie, the rim 3 and the middle rim 7, in the rim 3, the cut grooves 5 and 5, which are the connecting parts, are formed on the vertical surface 4 directly under the hollow cross member. By simultaneously molding the horizontal grooves 6 and 6 orthogonally to each other, and by simultaneously molding the vertical pieces 8 with vertical grooves 9 that serve as joint parts in the center band on both sides of the hollow vertical members in the middle beam 7, the upper and lower trunks between the columns 2 are formed. When attaching the center rim 7 to the rim 3, the vertical surface portion 4 of the rim 3 is fitted into the vertical groove 9 of the rim 7, and each vertical piece 8 is pushed from the front and back outward toward the horizontal groove 6 inside thereof. By the operation, the above-mentioned mid-rails 7 can be easily, reliably and quickly attached to the furring 3 at each position, so that the working efficiency of fencing assembly can be further improved. Further, in the above-mentioned installation, there is no need for preliminary work such as drilling holes, or fastening parts such as rivets or tapping screws, so that the cost of the fence can be significantly reduced. In addition, rainwater is reliably prevented from entering the interior of the rim 3 and the inside of the fence 7, thereby prolonging the durable life of the fence.

Incidentally, the present applicant has simultaneously filed a separate related application in Utility Model Application No. 1984-72454 (Utility Model Application No. 177661/1983). In this separate application, instead of the horizontal groove 6 of the present application, a U-shaped notch is provided adjacent to the cut groove 5, and each of the vertical pieces 8, 8 is pressed and deformed toward the notch. A convex body B is formed in pressure contact with the edge of the vertical piece 8, and each vertical piece 8 is clamped to the vertical surface part 4.

The difference in function and effect between the two applications is that the present application can be more firmly connected without any play. Further, the horizontal grooves 6 of the present application can be extruded at the same time as the furring 3, and the cut grooves 5 can be easily processed by cutting, etc., whereas the cut grooves and notches of the separate application require making a cutting die and press forming. Therefore, the present invention is easier to manufacture.
