DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a method for attaching wall panels to each other and a new wall element.
BACKGROUND OF THE INVENTION
According to a known method partition panels or wall elements, particularly in the installation of so-called cassettes used in shipbuilding, are attached to each other only at the floor and at the ceiling where the points of attachment can be protected with covering strips. The panels are not at all attached to each other in the middle because it would require separate protective strips to cover the points of attachment. The problem with this method of attachment is that gaps readily appear between the elements in the middle. Another problem is poor alignment of the elements which may lead to an uneven wall surface.
Various attachment mechanisms have also been suggested whereby the wall panels or elements can be attached to each other also in the middle or in practice over the entire height of the wall. These kinds of systems are often composed of various profiled strips which are, for example, placed against the edge of the panel or the element and are screwed fast at specific intervals. Therefore, attachment of these known profiled strips is in practice rather tedious.
SUMMARY OF THE INVENTION
The purpose of this invention is to eliminate the above problem and obtain a new method for attaching wall panels without the above drawbacks. The purpose of the invention is also to obtain a wall element comprising all tools needed in the attachment, the element being, according to the method, attachable to other similar elements.
By means of the invention wall panels can be firmly attached and accurately aligned with each other over the whole length of the panel. Installation is rapid because no screwing or the like is needed to be performed on the building site. The strips employed in the method have a simple structure and their manufacturing cost is low.
BRIEF DESCRIPTION OF THE DRAWING FIGURES
The invention will be described in the following referring to the enclosed drawings in which
FIG. 1 shows wall panels attached to each other as a perspective view partly cross-sectioned,
FIGS. 2A and 2B show the perforation of the edge sections of the wall panel,
FIG. 3 shows the structure of a tongue strip,
FIG. 4 shows the structure of a wedge strip,
FIG. 5 shows wall panels fitted adjacently seen from above,
FIG. 6 shows a cross-section of a joint along the line A--A of FIG. 5 before knocking down the wedge strip,
FIG. 7 shows the joint of FIG. 6 after knocking down the wedge strip,
FIG. 8 shows the structure of a wall element of wall panels placed against each other.
DETAILED DESCRIPTION OF THE INVENTION
FIGS. 1 and 5 show the attachment of adjacent wall panels L1 and L2 to each other. The first side edge 10 of the panel L1 is bent into an L-section and the second side edge 11 is bent into a Z-section. The bent L- and Z-sections are provided with holes 12, 12' respectively at a suitable interval from each other over the height of the wall panel in the manner shown in FIGS. 2A and 2B. The edges of the second panel L2 are bent in the same way. The L- and Z-sections of the panel L2 are also provided with holes 12, 12' respectively disposed in the same way as those of the panel L1 over the height of the wall panel. Thus the holes 12, 12' of the edge sections of both panels come opposite one another when the panel L1 is placed adjacent to the panel L2. The L-section of the second panel L2 is placed against the Z-section of the first panel L1 according to FIGS. 1 and 5. The perforated part 15 of the L-section of the second panel presses against the similarly perforated part 16 of the Z-section of the first panel. A tongue strip 20 with a U-profile, the structure of which appears in more detail in FIG. 3, is attached against the L-section of the panels by gluing or riveting, for example. The middle part 21 of the U-section of the tongue strip 20 is provided with upward pointing tongues 22 over the height of the strip. The tongues 22 are dimensioned and fitted so th
