  Has hexagonal through-holes for fitting and fixing steel nuts at the ends, has a light-weight cavity at the base between these ends, and spends saddle-shaped joints at the end of each end A hexagonal through-hole for fitting and fixing a steel nut on both sides of a light-weighted through-hole to the L-shaped block at the short end, and a hook-like connection that can be fitted with the hook-like connecting hand. The linear blocks with their hands arranged opposite to each other are interconnected by their hook-shaped connecting hands, and the ends are extended to a long L-shaped block, and each hexagonal through hole has a steel nut for bolt connection. The square pipe to be connected to the linear block and the end of the short L-shaped block connected to the linear block is fitted and fitted, and the end face of the square pipe is brought into contact with the base of the short L-shaped block. Connect the connection plate to one side of these connection square pipes in common, and pass this connection plate through. A steel pipe is fastened and coupled to each of the plurality of bolt coupling nuts, and the wall surface of the square pipe to be connected is sandwiched between the connection plate and the long L-shaped block surface. The present invention relates to a connection assembly of an aluminum L-shaped joint and an aluminum square pipe.

  It also has hexagonal through holes for fitting and fixing steel nuts at the ends, light weight cavities are perforated at the base between these ends, and hook-like connecting hands at the ends of the ends. A hexagonal through-hole for fitting and fixing a steel nut on both sides of a light-transmitting hollow cavity to the T-shaped block of the short end portion that has spent the same, and a gutter that can be fitted with the above-mentioned hook-shaped connecting hand Line-shaped blocks with opposing joints are connected to each other by their hook-like joints, and the ends are extended to a long T-shaped block, and each hexagonal through hole is made of steel for bolt connection. A nut is fitted, and the square pipe to be connected to the linear block and the end of the short T-shaped block connected thereto is covered and fitted, and the end face of the square pipe is brought into contact with the base of the short T-shaped block. Connect the connection plate to one side of these connection square pipes in common. The steel bolts are tightened and connected to each of the plurality of bolt connecting nuts, and the wall surface of the square pipe to be connected is sandwiched between the connecting plate and the long T-shaped block surface. The present invention relates to a connecting assembly of a characteristic aluminum T-shaped joint and an aluminum square pipe.

  Furthermore, the present invention relates to an assembly in which a steel pin is driven into the gap between the male and female fitting portions between the hook-like connecting hand of the short end block and the hook-like connecting hand of the linear block, thereby strengthening the above-described male-female fitting.

  In the above description, the present invention relates to an assembly in which an outer surface of a connecting portion between an aluminum L-shaped or T-shaped block at a short end and a linear block is reinforced and strengthened by aluminum welding.

  Further, in the above description, the present invention relates to nut fitting of an aluminum wire block.

  Further, in the above description, the present invention relates to an aluminum L-shaped or T-shaped block, an aluminum linear block, or an aluminum common connection plate at the long end portion and the short end portion.

  Furthermore, in the above description, the present invention relates to a method for connecting aluminum square pipes.

The block material joint of the present invention was developed for a storage rack of 80 or more seedling box storage shelves (for 80 sheets, 96 sheets, 120 sheets) because higher strength is required. Although it is basically a frame structure, it is a particularly important part in the frame structure because complex forces such as shear, compression, tension, and bending moment act on the joint.
The joint portion has a structure in which a square pipe is inserted into each of the T-shaped and L-shaped block members and fastened with a steel bolt from above the reinforcing plate.
The T-shaped block material has a structure in which an extension block material is fitted to a basic block material in order to extend the length.
Similarly, the L-shaped block material has a structure in which an extension block material is fitted to a basic block material.
In order to maintain strength, the above-described fitting method has a structure in which a steel pin is press-fitted and then welded together.
In addition, in order to firmly join the square pipe and the block material, a steel nut is press-fitted into the block itself, so that the joint is made of steel even in a relatively low hardness aluminum material, thus increasing the joint strength. At the same time, secular change becomes difficult.
