In the following description, the left and right of the drawing will be referred to as the left and right. Also, in the following description,
The term "aluminum" is intended to include aluminum alloys in addition to pure aluminum.

In this embodiment, the method of the present invention is applied to the joining of two aluminum extruded profile panels (1) and (2).

As shown in FIGS. 1 and 2, on the left side edge of the right aluminum panel (1) (first panel),
Form a sloped wall (3) that slopes upward toward the left. A groove (4) is formed in the right end of the lower surface of the inclined wall (3). In addition, a substantially L-shaped engaging portion (5) extending downward and bending to the right side at a portion on the right side of the inclined wall (3) of the right side panel (1).
Is formed.

The left aluminum panel (2) (second panel) is provided with a step (6) on the right edge of the panel (2).
The receiving portion (7) located below the upper surface of the is formed. The height of the step (6) should be equal to the thickness of the inclined wall (3) of the right panel (1). Further, a substantially L-shaped engaging portion (8) extending upward and bending leftward is formed at the right end of the receiving portion (7) via a connecting portion (9). The distance between the left end of the left bent part (8a) of the engaging part (8) and the right end of the receiving part (7) is the same as that of the right bent part (5a) of the engaging part (5) of the right panel (1). It is slightly larger than the width. The connecting part (9) is composed of a lower protruding part (9a) connected to the right end of the receiving part (7) and a right protruding part (9b) connected to the lower end of the receiving part (7), and the right end of the right protruding part (9b). Engaging part (8)
Are formed.

At the right side edge of the right side panel (1), the left side panel
Step (6) of (2), receiving part (7), connecting part (9) and engaging part
A step portion (6), a receiving portion (7), a connecting portion (9) and an engaging portion (8) similar to those of (8) are formed. An inclined wall (3) and an engaging portion (5) similar to the inclined wall (3) and the engaging portion (5) of the right panel (1) are formed on the left edge of the left panel (2). That is, both panels (1) and (2) have the same shape, and both are integrally formed by extrusion.

In joining the two panels (1) and (2), first, as shown by a chain line in FIG. 2, the right panel (1) is assembled from above the left panel (2) to form the right panel (1).
Of the left edge of the left panel (2) to the right end of the receiving part (7) on the right edge of the left panel (2) and the left end of the left bent part (8a) of the engaging part (8). From above, drop it onto the right protrusion (9b). Then,
The two panels (1) and (2) are moved away from each other, and the engaging portions (5) and (8) are engaged with each other as shown by the solid line in FIG. After that, the inclined wall (3) of the right side panel (1) is hit with a hammer or the like to pressurize it from above, and the inclined wall (3) is horizontally deformed and brought into close contact with the receiving portion (7). At this time, the groove
The function of (4) makes it difficult for the inclined wall (3) to return to the inclined state, so that the inclined wall (3) firmly adheres to the receiving portion (7). And the sloping wall
As (3) closely contacts the receiving part (7), the tip of the inclined wall (3) abuts the step part (6), and the engaging parts (5) and (8) are engaged with each other, Both panels (5) and (8) are joined (see FIG. 3). The upper surfaces of both panels (1) and (2) are flush with each other.

In the above embodiment, the method of joining the right and left two panels has been described. However, a panel having the same shape as the left panel is joined to the right side of the right side panel, or the left side of the left side panel is further joined to the right side. It is also applicable to joining panels having the same shape as the panels.

In the above embodiment, the left and right panels are both extruded aluminum, but the invention is not limited to this.

[0017]

According to the panel joining method of the present invention,
As described above, no special skill is required for joining the panels, which simplifies the work and reduces the cost.
