Wall boards or panel boards for use in interior construction and dry construction

Abstract

The invention relates to a board for use in interior construction, especially for producing new walls in a room or for paneling wall, ceiling or roof surfaces of a room. Said board is provided on at least two opposite ends, a first and a second end, with connecting means, especially having a groove-and-tongue design, for linking the board with other boards of the same kind. The connecting means facilitate a catch, snap-in or click-in connection with an adjoining board of the same kind. Additional fastening means are provided on the board itself or on two boards linked with each other for fastening the board on a support construction. The invention also relates to a method for producing new walls of a room or for paneling already existing wall, ceiling or roof surfaces of a room. According to this method, a first board is mounted, a second board is linked with the first board by establishing a catch, snap-in or click-in connection on the adjoining lateral edges of the two boards, and the second board is secured by additional fastening means.

Description

TECHNICAL FIELD [0001] The invention relates to a board for use in interior construction and dry construction, especially for producing new walls and facing shells of a room or for panelling wall, ceiling or roof surfaces of a room, and to an associated method. PRIOR ART [0002] Large-format boards, e.g. of plasterboard, which are fastened to suitable supports, are known from the domain of interior construction. In dry construction, for example, these boards are fastened to metal profiles to produce new partition walls. Alternatively, for the purpose of forming panellings, the boards can be fastened to a lathing joined to a wall, or they can be fastened to roof slopes such as, for example, the beams of a roof truss. The boards can be more than man-high and have a width of over 1 m. Such boards are known as “one-man boards” and have dimensions of, for example, approximately 1.50×1.00 m. In addition, larger standard boards exist with dimensions of, for example, 1.25×2.50 m, which can n...

Benefits of technology

[0012] Accordingly, there are provided on at least two opposite sides, a first and a second side, of the board coupling means which, upon coupling to other boards of the same type, render possible a locking coupling to the respectively adjacent board. These coupling means can be provided in the form of, for example, a tongue-and-groove design. In particular, the coupling means on two opposite sides are complementary of one another, so that the lateral edge of a board can be coupled in a locking or interlocking manner to the opposite lateral edge of a board of the same type. The term “locking coupling” in this context means that an at least brief deflection occurs in the region of the coupling, particularly at one of the involved portions, for example, at one of the groove cheeks bounding a groove, so that a (generally termed) locking projection, which is preferably over-dimensioned, can be accommodated. In other words, in the case of such a locking, snap-in or click-in coupling, a portion is moved in such a way that it passes through a dead centre, whereupon the portion moves back, at least partially, in a resilient manner so that the said locking projection is securely held. In the coupled state, the portion which is moved in this manner can still remain at least slightly deflected, so that a force continues to be exerted which draws the boards to one another. It is also conceivable, however, for there to be no deflection in the coupled state but, at the same time, for mutually coupled boards to be prevented from moving apart. In connection with the coupling means provided on the board which effect the locking coupling, it is to be emphasized that they are integrally provided on the board. In other words, they are produced directly in the board material, so that there is no need for expensive provision of additional coupling means.

[0073] In the case of a covered fastening of the board to a support structure by appropriate means, for example, by means of fastening clips, screws or nails, it is particularly advantageous if the boards permit a direct abutment of adjacent boards, for example, either by means of board material or by means of an intermediate adhesive or sealant, so that a particularly uniform, continuous design of the wall or ceiling panelling can be achieved, such as that which is achievable and known, for example, in the case of a papered or plastered surface.

Problems solved by technology

In both of the aforementioned publications, the locking of a panel is effected by means of the separate locking or retaining element, with the result that assembly is comparatively complicated, inflexible and subject to large tolerances.
