Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel joining method applied when assembling a wall or floor of a building by joining a plurality of panels.

In this specification, the top and bottom of the drawings are referred to as the top and bottom.

[0003]

2. Description of the Related Art Conventionally, joining of two panels on one side edge has been performed by welding.

[0004]

However, since the special skill is required to join the panels by welding as in the prior art, there is a problem that the work becomes difficult and the cost becomes high. In addition, there is a problem that the strength of the panel is lowered or distortion occurs due to the influence of heat during welding.

An object of the present invention is to provide a panel joining method which solves the above problems.

[0006]

A panel joining method according to the present invention is a method for mechanically joining two first and second panels together at their one side edge portions. A groove that opens upward is formed at one side edge of the panel, and projecting walls that project toward the other side wall are formed at the upper ends of both side walls of the groove. An expansion that has a downward protruding wall formed at the edge portion, is continuous with the lower edge of the downward protruding wall, and has a shape that can be fitted into the groove of the first panel, and has an expansion allowance of a substantially V-shaped cross section in the middle portion of the width. Forming an expandable part, combining both panels so that the expandable part of the second panel fits into the groove of the first panel, and pressing the expandable part from above to widen its width. Deform it so that both side edges are bulged between the both side walls of the groove of the first panel. Together, it is characterized in that for fixing the two panels to each other by press fit between the projecting walls and the groove bottom surface.

[0007]

In the first panel, a groove opening upward is formed at one side edge portion, and projecting walls projecting toward the other side walls are formed at the upper ends of both side walls of the groove. A lower projecting wall is formed on one side edge of the second panel, and is shaped to be continuous with the lower edge of the lower projecting wall so as to fit into the groove of the first panel and has a substantially V-shaped cross section in the middle part of the width. Forming an expandable part having a stretch margin of
The expandable part of the panel is assembled so as to fit in the groove of the first panel, and the expandable part is pressed from above to be deformed so as to widen its width, and both side edges thereof are formed into the first part.
Since both panels are fixed to each other by pressing both side walls of the groove of the panel and press-fitting between the protruding wall and the bottom surface of the groove, no special skill is required for joining the panels. Moreover, since the panel is not heated during the joining, the panel is not affected by the heat.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

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, a groove (3) that opens upward is formed in the left side edge of the right panel (1) (first panel), and the groove (3 ) Left and right side walls
Projecting walls (4) and (5) projecting toward the other side walls (3b) and (3a) are formed at the upper ends of (3a) and (3b). The height of the left side wall (3a) of the groove (3) is set lower than the height of the right side wall (3b), and the upper surface of the protruding wall (5) at the upper end of the right side wall (3b) is attached to the panel.
(1) Keep it flush with the top surface. Further, an inclined part (6) inclined upward is formed on the left side edge of the bottom surface of the groove (3), and an inclined part (7) inclined upward on the right side edge and an upper end of the inclined part (7). Form a flat part (8) connected to the.

A downward projecting wall (9) is formed on the right side edge of the left panel (2) (second panel), and the downward projecting wall is formed.
(9) A strip-shaped expandable part (10) is formed on the lower edge of the (9). An extension portion (11) having a substantially V-shaped cross section is formed in a portion of the expandable portion (10) on the right side of the downward protruding wall (9). The left end of the expandable part (10) projects to the left of the downward projecting wall (9), and the wall thickness of that end is the groove (3) of the right panel (1).
It is slightly larger than the distance between the upper end of the slope (6) on the left side of the bottom surface and the lower surface of the protruding wall (4). In addition, the expandable part (1
On the right edge of (0), the flats (8) on the bottom of the groove (3) on the right panel
The rising wall (10a) having a height slightly larger than the distance between the lower surface of the protruding wall (5) and the lower surface of the protruding wall (5) is formed. Further, concave grooves (12) are formed on the lower surface of the top of the stretchable space (11) and the upper surfaces of the left and right side edges.

At the right side edge of the right side panel (1), the left side panel
The downward protruding wall (9) and the expandable portion (10) similar to the downward protruding wall (9) and the expandable portion (10) of (2) are formed. A groove (3) similar to the groove (3) of the right panel (1) is formed on the left edge of the left panel (2). That is, both panels (1)
(2) has the same shape, and both are integrally formed by extrusion.

When joining both panels (1) and (2), first, as shown in FIGS. 1 and 2, the left side panel (2)
Fit the expandable part (10) of the above into the groove (3) of the right side panel (1). Then, the expansion allowance (10) of the expandable part (10) is hit by a hammer or the like from above to pressurize it and deform it so that its width expands.
Between both side walls (3a) and (3b) of the expandable part (10), and press the left edge of the expandable part (10) between the left protruding wall (4) and the upper end of the inclined part (6) and the rising wall. (10a) to right side protruding wall (5)
Both panels by press-fitting it between the flat part (8)
Fix (1) and (2) to each other (see Figure 3). At this time, the groove
The function of (12) makes it difficult for the expansion allowance (11) of the expandable part (10) to return to its original state. In the joined state, 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. Further, since the panels are not heated at the time of bonding, it is possible to prevent the strength from being lowered or the distortion from being generated due to the influence of heat.
