The side edges are elastically locked to the locking portions installed by bending the side edges in the molding outer shell 3 so as to stand upright over the entire length in the longitudinal direction. On both sides of the aluminum thin plate, both sides of the aluminum plate are bent in the same direction in the left-right direction, and the front and rear protrusions 11 each having a thickness of 0.3 mm are formed at 1 mm intervals corresponding to the wall thickness of the standing fins 5. The front and rear projecting pieces 11 and the partition wall between them are elastically locked to the locking portion that is installed by bending the other end into a letter-like shape inside the molding shell 3 on the other side. Twelve according to 1
A joint strip 10 having a U-shaped or an approximate shape having a fitting groove 13 with a width of mm is formed to project over the entire length in the longitudinal direction, and the joint strip 10 of the same shape is also formed in series on the other side surface in the longitudinal direction by roll forming. It is formed as a protrusion.

In the joining of the horizontal rails 1 and the vertical rails 2 formed in this way, the standing fins 5 of the horizontal rails 1 are notched into an inverted T-shape, and an expanding receiving hole 7 is provided at an intermediate position in the vertical direction. A pair of vertical slits 6 and a pair of joint strips 10 on both sides of the vertical rail 2 in which the partition wall 12 between the front and rear projecting pieces 11 is inserted into the vertical slits 6 and the expansion receiving hole 7 is fitted with the front and rear projecting pieces 11. And a deformed portion 14 which is obtained by partially deforming the front and rear projecting pieces 11 of the joint strip 10 and fitted into the expansion receiving hole 7, and the deformation portion 14 is provided at the upper and lower ends of the expansion receiving hole 7. It is configured as a wavy press deforming portion which is fitted and locked in a cross shape in the front-rear direction and which has a wave surface in the left-right direction and which projects in and out.

In this embodiment, the vertical slits 6 are formed by notching the standing fins 5 at two positions separated according to the joining position of the vertical crosspieces 2, and the standing tongue pieces 8 due to the remaining standing fins are cut between them.
While forming the section, the cutout is formed into a T shape so that it has a rectangular shape at the intermediate position in the vertical direction so as to bite into the end of the standing fin 5 on the non-opposing side in this example, that is, the non-standing tongue piece 8 side. There is a pair of vertically symmetrical type having each expansion receiving hole 7 that is expanded into a pair, and the partition wall 12 of the joint strip 10 is inserted into the pair of vertical slits 6 and the front and rear projections 11 of the expansion receiving hole 7 are formed. As for the fitting, at the end of the vertical bar 2 in the longitudinal direction, for example, the vertical bar 2 abuts on the base of the horizontal bar 1 in the insertion slit 9 provided by removing the synthetic resin material 4 with a vibration cutter. As described above, while receiving the upright tongue piece 8, the partition walls 12 of the joint strips 10 of the vertical bars 2 are inserted into the pair of vertical slits 6 in a cross shape, and the end of the upright fins 5 and the expansion receiving hole 7 are moved forward and backward. As performed so as to be fitted in the fitting groove 13 between the projecting pieces 11. That.

The deforming portion 14 applies a pressing pressure in the front-rear direction to the front-rear projection piece 11 of the joint strip 10 in which the expanded receiving hole 7 is fitted, by using a pressing device (not shown). 11
Is partially deformed and is fitted into the expansion receiving hole 7, and at this time, a wavefront of about 1 pitch is formed in the left-right direction by using a press die in which the deformation is matched with the expansion receiving hole 7. The vertical protrusions and the vertical recesses are formed in a corrugated rib shape so as to project and retract in the front-rear direction and are formed in the expansion receiving hole 7 so as to bite in the front-rear direction. In addition, it is a wavy press deformed portion that is crosswise in the front-rear direction.

By fitting and locking in the receiving hole 7, the corrugated rib-shaped vertical projections and the wave fronts of the vertical recesses in the deformed portion 14 are fitted in the expanded receiving hole at the upper and lower ends thereof in a crossing shape and hooked. The vertical bar 2 is joined in both the up and down direction and the left and right direction,
In particular, it exhibits a strong joint strength against external force and twisting force in the pulling direction, and it is possible to secure sufficient joint strength against external force. Furthermore, in this example, a thin aluminum sheet forming material is also used. The horizontal rails 1 and the vertical rails 2 having the synthetic resin material 4 as a strength element by being filled with the synthetic resin material 4
With the use of, it is possible to change the material with excellent strength, and since the deformed portion 14 is formed into a corrugated press deformed portion by press molding, the molding process becomes easy and reliable, and the joining of the crosspiece A is achieved. It can be suitable.

Although the illustrated example is as described above, in the practice of the present invention, the horizontal rail and the vertical rail are assumed to have an integral standing fin made of aluminum extruded material or a pair of joints on both sides, and the joining is performed. At this time, the aluminum extruded material is further formed by a thin-walled aluminum extruded material for resource saving and a synthetic resin material filled in the molded outer material so as to serve as the strength element. In this case, the standing fins and the joint strips can be formed of aluminum extruded material integrally molded on the horizontal rail and the vertical rail, and the joint strip can be formed thin. In this case, the aluminum thin plate forming material was used. Similar to the case, it has a bonding strength and can be suitable for bonding.

Further, a pair of vertical slits having an expansion receiving hole are formed by notching the upright fins in an inverted T-shape in which the expansion receiving hole is arranged so as to bite into the opposite side, that is, the upright tongue side. In this case, instead of the above-mentioned U-shape or a shape similar thereto, for example, an H-shape or a shape similar thereto is used, and press molding is applied to the front and rear projecting portions of the partition wall on the vertical bar base side. Including the fitting and locking of the deformed part, and the fact that when the molded outer shell is filled with the synthetic resin material of the strength element, the foamed one or the hard molded one is post-inserted and fixed. Therefore, the specific mode can be variously modified without departing from the gist of the invention.
