<Problems to be solved by the invention> In the case of welding, welding marks are unsightly and
Rust occurs in a relatively short period of time. Furthermore, in the case of using screws or rivets, it is necessary to drill a hole and pass the screw or rivet through the hole, so it is not suitable for mechanized processing and assembly for mass production.

<Means for solving the problem> Therefore, the invention as claimed in claim 1 is directed to a hollow vertical member and a horizontal member that are brought into contact with each other by crossing each other at their contact walls and are fixed in that state. In the method of cross-linking timbers, the contact wall of the cross member is provided with a series of fin rays whose tips protrude toward the hollow longitudinal member, and the contact wall of the hollow longitudinal member is provided with a series of fin rays having a thickness of the fin rays. A horizontal slit is formed corresponding to the horizontal member, and two grooves are formed in the fin rays of the horizontal member at the positions where the hollow vertical member is connected, from the tip to the horizontal member, passing through both side walls of the hollow vertical member. The space between both of the kerfs is defined as an intermediate piece, and the intermediate piece is provided with a lateral groove extending halfway along the outer surface of the contact wall of the cross member from the back of one or both of the kerfs, and the fin rays are Insert the intermediate piece into the hollow part through the slit of the hollow vertical member, and at the same time insert the both side walls of the hollow vertical member into the two grooves in the fin rays so that the contact walls of both members cross and come into contact. The intermediate piece was then twisted within the hollow part of the stringer so that the edge of the transverse groove facing the contact wall of the crosspiece came into contact with the inner surface of the contact wall of the stringer.

Further, the invention of claim 2 provides a method for cross-connecting a hollow vertical member and a horizontal member, in which the hollow vertical member and the horizontal member are brought into contact with each other at their contact walls, and are fixed in that state. The contact wall of the material is provided with a series of fin rays whose tips protrude toward the hollow longitudinal member, and the contact wall of the hollow longitudinal member is provided with transverse slits corresponding to the thickness of the fin rays. In the fin rays of the horizontal member, two grooves are formed from the tip toward the horizontal member to pass through both side walls of the hollow vertical member at the position where the hollow vertical member is connected, and a groove is formed between the two grooves. an intermediate piece, and the intermediate piece is provided with a cut along the outer surface of the contact wall of the horizontal member, and the intermediate piece of the fin ray is inserted into the hollow part through the slit of the hollow vertical member, and at the same time, both side walls of the hollow vertical member are inserted. The intermediate piece is inserted into the two grooves in the fin rays so that the contact walls of both pieces cross over and come into contact with each other, and then the intermediate piece is twisted inside the hollow part of the vertical member, and the edge of the cut is inserted into the contact wall of the vertical member. It was designed so that it came into contact with the inner surface of the

<Example> In each of the illustrated examples, V indicates a hollow vertical member, and H indicates a horizontal member. Both members V and H are extruded from aluminum and manufactured to have a wall thickness of approximately 0.8 to 1.5 mm. The hollow longitudinal members may be pipes, which may be made of stainless steel, and the cross members may be hollow pipes or C-section members.

Both materials are in contact at contact walls 1 and 2, respectively, and intersect at right angles here. The cross member H has integrally a series of fin rays 3 which project from the contact wall 2 with their tips towards the longitudinal member. The thickness of this fin ray 3 should be approximately the same as the wall thickness of the horizontal member.

In this fin ray 3, two grooves 4, 4 are formed from the tip toward the horizontal member, allowing passage of both side walls v, v of the vertical member, at intervals where the longitudinal members should be connected. The portion between the kerfs 4 and 4 is defined as an intermediate piece 5.

On the other hand, slits 6 in the horizontal direction corresponding to the thickness of the fin rays 3 are provided in the contact wall 1 of the vertical member V at a plurality of positions in the vertical direction to connect with the horizontal member.

Therefore, the intermediate piece 5 of the fin ray 3 is inserted into the hollow part through the slit 6 of the vertical member, and both side walls v,
By inserting the contact walls 1 and 2 of the vertical member V and the horizontal member H into each other at right angles, the contact walls 1 and 2 of the vertical member V and the cross member H can be brought into contact with each other at right angles by inserting the contact walls 1 and 2 of the vertical member V and the horizontal member H by inserting the contact grooves 4 and 4 in the pair of kerfs 4 and 4 of the fin rays 3, respectively.

In the first embodiment shown in Figs. 2 to 6, the back of one of the two grooves 4, 4 of the fin ray 3 reaches the outer surface of the contact wall 2, but the back of the other reaches in front of the outer surface of the contact wall. at the ends, maintaining a spacing between them approximately equal to the thickness of the contact wall 1 of the longitudinal member. The deep end of the kerf that reaches the outer surface of the contact wall communicates with a transverse groove 7 that extends halfway along the outer surface of the contact wall toward the other kerf. The width of this groove 7 may be equal to the thickness of the contact wall 1 of the stringer, or as shown, it may be equal to the thickness of the contact wall 1 of the stringer at one end but gradually narrows towards the other end. It may be tapered.

The slits 6 in the longitudinal members are formed from the outer surface of the contact wall 1 by the thickness of the contact wall 1.

As a result, as mentioned above, the contact wall 1 of both materials V and H,
After the two pieces are brought into contact at right angles, the corner part 5' where the cut grooves 4 and grooves 7 of the intermediate piece 5 intersect is cut with a tool from the open end of the vertical member and twisted to perform the connection. . In this case, as described above, if the width of the groove 7 is gradually narrowed to a tapered shape and is set to be smaller than the thickness of the contact wall 1 of the vertical member, the narrow edge of this groove becomes the contact wall 1 of the vertical member. It bites into the inner surface of the tube to increase the strength of the connection.

In the second embodiment shown in FIGS. 7 and 8, the two grooves 4 and 4 of the fin ray 3 both reach the outer surface of the contact wall 2 at the back,
Transverse grooves 7, 7 extending halfway along the outer surface of the contact wall 2 toward each other are connected to the inner part thereof.

In this embodiment, therefore, the two corners 5', 5' of the intermediate piece 5 can be twisted and connected using a tool from the open end of the longitudinal member. Note that the cross member H in this embodiment is a C-shaped cross-section member, and the contact wall 2
An auxiliary fin ray 3' is provided parallel to the fin ray 3.
Then, in this auxiliary fin ray 3', a notch 3a having the same width as the contact wall 1 of the vertical member is formed at the same position as the kerfs 4, 4 of the fin ray 3, and grooves 4, 4, and an intermediate piece 5 are formed. At the same time, the vertical members are fitted into the notches 3a by forming them at the same time,
It is possible to more effectively prevent the vertical members from moving and rattling along the horizontal members.

The slits 6 of the vertical members V in both the first and second embodiments described above are formed over the entire width of the contact wall 1, that is, including the joints with both side walls v, v, so a plurality of vertical members are lined up and cut into It can be easily processed.

Also, the cut grooves 4, 4 on the fin rays of the cross member H, and the intermediate piece 5
This can be easily done by pressing while intermittently feeding the horizontal members at the mounting intervals of the vertical members.

The intermediate piece 5 of the third embodiment shown in FIG. 9 is almost the same as the second embodiment, except that a groove 5a is formed halfway from the center of the tip of the intermediate piece 5 toward the contact wall 2 of the cross member. , it is easier to twist and bend both corner portions 5', 5' with a tool.

Transverse slits 6 formed in the contact walls 1 of the longitudinal members
In this embodiment, they are formed except for the joints with the side walls v, v, that is, in accordance with the spacing between the opposite sides of the side walls. As mentioned above, this slit 6 cannot be formed by sawing, so it is formed by pressing. Since this slit remains at the joint with both side walls,
It is superior to sawing in that it does not reduce the strength of the vertical members.

In both the vertical members of the fourth embodiment shown in FIG. 10 and the fifth embodiment shown in FIG. 11, horizontal slits 6 are formed in the contact wall 1 by sawing.

In the fourth embodiment, the depth of the two grooves 4, 4 formed in the fin rays 3 of the horizontal member is the same as the thickness of the contact wall 1 of the vertical member, or slightly narrower between the outer surface of the contact wall 2 and the outer surface of the contact wall 2. Keeping distance. Similarly, between the intermediate piece 5 and the contact wall 2 of the horizontal member, there is maintained a distance equal to or slightly narrower than the thickness of the contact wall 1 of the vertical member, and a gap is placed at the back of the two grooves 4, 4. A communicating transverse cut 8,8 is formed. Therefore, in this embodiment, as in the second embodiment shown in FIG. A bending connection can be made.

The kerfs 4, 4 in the fifth embodiment maintain a distance from the outer surface of the contact wall 2 which is greater than the thickness of the contact wall 1 of the longitudinal member. For this reason, the horizontal slits 6 formed in the longitudinal members are formed deep accordingly.

In this embodiment, there is a contact wall 2 at the back of one of the kerfs 4.
A substantially L-shaped cut 8 is formed in the intermediate piece 5, extending halfway toward the outer surface of the contact wall 2, and then curvedly extending substantially parallel to the outer surface of the contact wall 2. Therefore, the connection can be achieved by cutting the corner portion 5' of the intermediate piece 5 surrounded by the cut 8 with a tool.

The part of this cut 8 extending substantially parallel to the outer surface of the contact wall 2 may be kept at a distance equal to the thickness of the contact wall 1 of the longitudinal member, but with a distance between it and said outer surface equal to the thickness of the contact wall 1 of the longitudinal member. By narrowing the spacing slightly or by gradually narrowing the spacing from one end to the other as shown in the figure, the edge of the section can be made into a contact wall of the vertical member, as described in the first embodiment. It bites into the inner surface of 1 and increases the connection strength.

In the sixth embodiment shown in FIG. 12, a slit 6 is formed in the contact wall 1 of the vertical member V by press working. The depths of the two grooves 4, 4 in the fin rays 3 of the cross member both reach the outer surface of the contact wall 2. A U-shaped cut 8 is formed in the intermediate piece 5 toward the outer surface of the contact wall 2.

Therefore, in this embodiment, the connection can be achieved by cutting the portion 5' of the intermediate piece 5 surrounded by the U-shaped cut 8 with a tool. Similar to the fifth embodiment, the intermediate portion of this cut 8 facing the outer surface of the contact wall 2 maintains a distance equal to the thickness of the contact wall 1 of the longitudinal member from the outer surface of the contact wall 2. However, a high connection strength can be obtained by making it a little narrower than that, or by making it gradually narrower from one end to the other as shown in the figure.

In each of the illustrated embodiments, the fin rays 3 provided on the contact wall 2 of the cross member protrude from the middle of the height of the contact wall 2, but of course they may also protrude from the upper or lower edge of the contact wall 2. .

Further, the cross-sectional shape of the vertical member is not limited to the rectangular shape shown in the figure, and the contact wall 1 may be curved convexly or concavely, or for example, as shown in FIG. , or the wings W may protrude outward from both side walls.

<Effects of the Invention> According to the present invention, the horizontal slits 6 in the contact wall 1 of the vertical member can be easily formed by sawing or press working, and two slits 6 are formed in the fin rays 3 of the contact wall 2 of the horizontal member. Processing to form the cut grooves 4, 4 and create the intermediate piece 5 between them can also be easily performed using a press.

Further, after the contact walls of both the vertical and horizontal members are crossed and brought into contact with each other, the intermediate piece 5 can be twisted from the end of the vertical member within the hollow portion thereof by pressing.

Then, the intermediate piece 5 is twisted, and the edge of the transverse groove of the intermediate piece facing the contact wall of the cross member and the edge of the cut are brought into contact with the inner surface of the contact wall of the vertical member. Since it is strongly pressed and fixed, there is no vertical angle between the two materials.
There is no gap between the two pieces, which allows the two pieces to be connected without any wobbling.At the same time, because the intermediate piece protrudes into the slit of the longitudinal piece, the longitudinal piece cannot move vertically relative to the cross piece, and the cut groove The vertical members cannot move laterally either due to the edges of the adjacent fin rays 3.

Thus, the present invention has an excellent feature of increasing the productivity of gates, fences, window lattices, etc. in which a large number of vertical lattices are attached to the horizontal rails, and enables mass production.
