DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint structure of wall panels connected by a real joint.

[0002]

2. Description of the Related Art A conventional wall panel is formed with a real portion having a shape engaging with a side surface of an adjacent wall panel on both side surfaces so that a plurality of wall panels can be jointed. There is. The above-mentioned real part is formed in the height direction of the wall panel in such a manner that one side surface part is a real convex part and the other side part is a real concave part, and the book part of the adjacent wall panel is formed. By fitting the actual convex portion and the actual concave portion, the wall panels are connected so as not to be displaced in the thickness direction between the wall panels, and the surface portion is formed flush with no step.

[0003]

However, in the conventional joint structure by the actual joining, both the actual convex portion and the actual concave portion are formed up to the upper and lower edges of the side surface of the wall panel. As a result, even in the fitted state, the panel is slid in the height direction due to the cut-out state in the height direction, so that there is a problem that the panels are fixed at different heights from each other. There was such a case. If there is a level difference in the horizontal direction of the wall panel where multiple pieces are connected, it will not be possible to join with other panel members such as floor panels and ceiling panels, or there will be gaps at the joints, which will adversely affect the entire construction Will affect you. For this reason, in the conventional wall panel assembling work, before the panels are connected and fixed to each other, an adjustment operation is performed to adjust the heights of the panels so as to form a series in a horizontal direction. This not only makes the adjustment work difficult, but also has problems in efficiency and accuracy of the assembly work. The present invention provides a real part in which the sliding in the height direction at the joining point is suppressed, and an adjusting operation or the like that makes the upper and lower edges of the wall panels horizontal in a series is unnecessary. It is an object of the present invention to reduce the working time required for assembling a wall panel and to improve assembling accuracy.

The present invention has been made in view of the above circumstances, and an object thereof is to provide an engaging means for positioning an adjacent wall panel in the height direction at the upper and lower ends of a real part. It is an object of the present invention to provide a joint structure of a wall panel in which continuous formation is performed to shorten the assembling time and improve the assembling accuracy for the splicing of the wall panel.

[0005]

In order to achieve the above-mentioned object, the present invention is directed to a shape in which one side portion of a wall panel is fitted with a real convex portion and the other side portion is fitted with the real convex portion. In the connecting structure of the wall panels formed by connecting the side portions of the adjacent wall panels with each other by real joining, the actual convex portions and The present invention has a wall panel connecting structure in which the upper end and the lower end of the real recess are set at positions spaced apart from the upper and lower edges of the side surfaces of the wall panel by a required distance. Further, in the above structure, the engaging portion having a shape opposite to the shape of the real portion is formed continuously from the upper and lower ends of the real portion to the upper and lower edges of the side surface of the wall panel. is there. According to such a configuration, when the joining is performed by the actual splicing, the adjacent wall panels become a series in the height direction and the thickness direction, and adjustment work such as horizontal alignment before connection and fixing is performed. This eliminates the need for this and shortens assembly time and improves assembly accuracy.

[0006]

FIG. 1 is a block diagram showing an embodiment of the present invention.
This will be described in detail with reference to FIG. FIG. 1 shows an embodiment of the present invention. A real part consisting of a real concave part 2 on one side 1a and a real concave part 3 on the other side 1b is formed at a relative position of both side parts 1a and 1b of the wall panel 1 in a predetermined dimension in a height direction. It is provided so that it can be joined to the wall panel 1 of the same type that is formed and juxtaposed by real joining. In the real part, the actual convex portion and the upper end portion 2a of the real concave portion are provided. 3a and lower ends 2b, 3b are set at locations spaced apart from the upper and lower edges of the side surfaces 1a, 1b by a predetermined distance L, respectively.

[0007] Therefore, in order to joint the same type of wall panels 1 and 1, the real convex portion 2 and the real concave portion 3 formed on the side surfaces of each other are connected in the height direction and the thickness direction. If they are not completely matched, they will not be in a joined state.

Therefore, in the assembling work, the joints are simply completed without the need for adjustment work such as alignment in the height direction, by merely fitting the real parts, and the wall panels of each other can be formed only by this. Are successively aligned in the horizontal direction, and the panel surface portions 10 and 10 are connected flush with each other without forming a step or the like in the joint portion as in the conventional structure.

In addition, in the case of the actual joint of the actual convex portion 2 and the actual concave portion 3 formed in this manner, the wall panels do not slide in the height direction, so that they are fixed. The fixing work performed by the plate, the connecting tool and the like becomes easy, so that not only the working time is shortened, but also the assembling accuracy is improved.

FIG. 2 shows another embodiment, in which the upper and lower edges of the actual portion located at the above-mentioned required distance L from the upper and lower edges of both side portions of the wall panel are provided. An engagement portion that fits into each other is formed by a concave-convex shape different from the shape of the real portion.

In this case, one side 1a of the wall panel 1
An engagement recess 21 having a shape opposite to that of the actual convex portion is formed continuously between the upper edge of the actual convex portion and the upper end portion 2a of the actual convex portion. Then, an engagement recess 21 is also formed between the lower end edge of the side surface portion 1a and the lower end portion 2b of the actual convex portion.

On the other hand, in the side surface portion 1b where the real concave portion 3 is provided, an engaging convex portion 31 having a shape opposite to that of the real concave portion is formed from the upper end portion 3a of the real concave portion 3 to the side surface. It is formed continuously over the upper edge of the portion 1b, and similarly, the side portion 1b
An engagement projection 31 is also formed between the lower end edge of the main recess and the lower end 3b of the real recess.

That is, the side surface portion 1a formed so that the real convex portion 2 is sandwiched between the engaging concave portions 21 formed on the same axis from the upper and lower ends thereof, and the opposite real concave portion. And a side portion 1b formed so as to be sandwiched between engagement protrusions 31 formed on the same axis from the upper and lower ends thereof. At the time of installation, the engaging portion composed of the engaging concave portion 21 and the engaging convex portion 31 is fitted so that the height directions of the opposed side portions 1a and 1b coincide with each other. The real part consisting of the real recess is also fitted,
The joining is performed in a state where the height direction and the thickness direction are both aligned and the alignment is performed.

Thus, at the joint of the adjacent wall panels, the real portion and the engaging portion are connected to each other by a reverse fitting manner, so that the strength in the shearing direction at the joint is reinforced. In addition, it is possible to prevent the occurrence of a gap that causes light leakage or the like. In addition, since a sound insulating effect can be obtained, it is suitable for a case where a wall or the like of a soundproof room is formed.

[0015]

As described above, according to the present invention,
By setting the upper end and the lower end of the real convex portion and the real concave portion at positions separated by predetermined intervals from the upper and lower edges of the side surface of the wall panel, adjustment work such as alignment in the height direction is required. Since the joints are simply made without any trouble and the wall panels arranged side by side do not slide in the height direction, the fixing work performed by the fixing plate or the connecting tool is facilitated, and the working time is shortened. Not only that, it also has an excellent effect of improving the assembling accuracy. Further, between the upper end edge and the lower end edge of the wall panel both side surface portions and the upper end portion and the lower end portion of the real part, an engaging part that fits with each other is formed by an uneven shape different from the shape of the real part. Thus, in addition to the above-described effects, an effect is obtained in which the connection strength at the joining portion is increased and a gap is hardly generated.
