[Prior Art] Various bonding structures for bonding channel materials have been proposed. Utility Model Application No. 61-140851 and No. 140852 filed by the present applicant relate to an end joint structure exclusively for channel materials having a groove and a hollow portion having a trapezoidal cross section on the longitudinal side surface. This connector includes a mounting face plate on the side surface and a closing face plate on the end face, and the mounting face plate is provided with a retaining member that engages from the groove and locks. [Problems to be solved by the invention] In both cases, the unbalanced load from the side of the channel material depends on the locking force of the retaining member from the side groove of the channel material to the hollow part, so a large unbalanced load Due to the design, anxiety cannot be avoided with furniture that hangs. In this case, it is also necessary to consider the occurrence of loosening due to the return of the retaining member. Furthermore, since the channel material is usually formed by cutting an extruded material, edges are present at the ends. When assembling the ends in a cross-butted state, the edge of one channel material end will be exposed, and the edge of the other channel material end will come into contact with the side surface of one channel material, avoiding the risk of causing damage. It was something I couldn't do. In this case,
With the scaffolding joint No. 17950, not only is it not possible to assemble the ends butt-to-edge, but it is also difficult to place the ends of the long scaffolding in the same line with the assembled protrusion and at the correct insertion position. It was difficult to set up and had poor workability. Furthermore, since the channel material described above has a hollow part in the center in addition to the trapezoidal hollow parts on the sides, it has been desired to make effective use of these hollow parts to increase the bonding strength. Therefore, it is an object of the present invention to enable channel materials having a plurality of hollow portions to be easily joined together. [Means for Solving the Problems] The present invention for solving the above problems provides an end portion of a channel material comprising a central hollow portion and a hollow portion having a substantially trapezoidal cross section and a groove portion in the longitudinal direction of the side surface. The device is for connecting the channels in a cross-butting state, and is provided with mounting face plates that are integrally connected in an L-shape and close the ends of the channel material, and the inner side of one mounting face plate and the outside of the other mounting face plate are connected to each other. The insertion rod is inserted into the side hollow part and the reinforcing rod is inserted into the central hollow part, and the insertion rod has a trapezoidal cross section and is longer than the reinforcing rod. The configuration includes screw holes for fixing. [Function] The inside of one mounting face plate is brought close to the end of one channel material, and the insertion rod is inserted into the side hollow portion, and the reinforcing rod is inserted into the central hollow portion. After that, the channel material is screwed and fixed through the screw hole of the insertion rod. In this reinforced and connected state, the side surface of one channel member is in contact with the mounting surface portion of the other channel member. Similarly, the other channel material is brought close to the other mounting face plate, and the insertion rod and reinforcing rod are inserted into the side hollow portion and the central hollow portion, and fixed with screws. On the other hand, the end of the channel material is covered with one mounting face plate, and the end of the other channel material is reinforced and connected to the one channel member while being covered with the other mounting face plate. [Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1 to 5. The connecting structure connects one channel material 2, in which a plurality of hollow parts are arranged in parallel, to the other similar channel material 1. The channel materials 1 and 2 include a rectangular tube portion 7 with a square cross section located at the center, and flat plate-shaped extension portions 9 extending radially outward from each corner portion 8 of the rectangle tube portion 7.
...and the L-shaped portion 1 extending from the extending portion 9...
0... can be used. Four spaces 11 having a trapezoidal cross section are formed around the rectangular tube part 7, and each space 11 corresponds to the groove part 1.
2 is open to the outside. The space 11
is configured as a side hollow portion 3, and the internal space of the square tube portion 7 is configured as a central hollow portion 5. Next, the mounting plate 15 that connects the channel materials 1 and 2 can be constituted by, for example, mounting face plates 16 and 17 that are connected in an L-shape. Insertion rods 4 can be protruded from the inside of one mounting face plate 17 and the outside of the other mounting face plate 16. Above insertion rod 4
is formed into a columnar shape with a trapezoidal cross section so that it can be inserted into the side hollow portion 3 of the channel material 1, for example. In this case, the insertion rod 4 is inserted into the side hollow portion 3 and connected to the channel materials 1 and 2 , and for this purpose, the insertion rod 4 is provided with a screw hole 1.
8 and 18 are formed, and the channel materials 1 and 18 are formed.
Screw holes 19, 19 communicating with these screw holes 18, 18 are formed in the square tube portion 7 of No. 2. Screws 2 screwed into the screw holes 18, 18, 19, 19
0 and 20, the insertion rod 4 is connected to the channel members 1 and 2 . Above insertion rod 4
A protrusion 21 that engages with the groove 12 is formed on the groove 12 . Further, the reinforcing rod 6 may be configured to protrude from the mounting face plates 16 and 17 and be inserted into the central hollow portion 5 of the channel members 1 and 2 . The reinforcing rod 6 can have a cylindrical shape shorter than the insertion rod 4. Next, the operation will be explained. In advance, one of the mounting face plates 17 is attached to one of the channel members 2 to be assembled as shown in FIG. That is, the inside of one mounting face plate 17 is brought close to the end of one channel material 2, and the insertion rod 4 is inserted into the side hollow part 3 using the protrusion 21 as a guide. If the reinforcing rod 6 is inserted into the central hollow portion 5 using this insertion as a guide, the reinforcing rod 6 will be inserted without buckling. Thereafter, the screws 20, 20 are screwed and fixed from the screw holes 18, 18 of the insertion rod 4 to the screw holes 19, 19 of one of the channel members 2 . In this reinforced and connected state, as shown in FIG. 1, the side surface of one channel member 2 is in contact with the other mounting surface portion 16. Similarly, the other channel member 1 is brought close to the other mounting face plate 16, the insertion rod 4 and the reinforcing rod 6 are inserted into the side hollow portion 3 and the center hollow portion 5, and fixed with screws. As shown in FIGS. 2 and 3, the end of one channel material 2 is covered with one mounting face plate 17, and the end of the other channel material 1 is covered with the other mounting face plate 16.
One channel material 17 is covered with
Reinforcement is bonded to the sides. For example, as shown in FIG. 5, even if the channel material 1 receives an uneven load F from above, the uneven load F can be supported by both the insertion rod 4 and the reinforcing rod 6. , channel material 1, 2
are strongly connected. Further, FIG. 6 shows a second embodiment. The feature of this embodiment is that another mounting plate 22 is provided perpendicular to the mounting plates 16 and 17, and an insertion rod 4 and a reinforcing rod 6 are provided protruding from the mounting plate 22. Thereby, another channel material 23 having a similar structure can be attached from the other side as well. [Effects of the Invention] As explained above, the present invention provides the following effects. An insertion rod and a reinforcing rod are respectively provided protruding from the inside of one mounting face plate and the outside of the other mounting face plate, which are integrally connected in an L-shape. Since it is formed long and provided with screw holes, it is possible to connect each end of the channel material with each mounting face plate covered without exposing the edges in the L-shaped cross-butting state, and the insertion rod Unbalanced loads, etc., can be dispersed by using the reinforcing rods and the cross joints for the ends of the channel material, which are beautiful and strong, can be put to practical use. In addition, the reinforcing rod can be easily inserted into the end of the channel material using the long insertion rod as a guide.
