Abstract

Dans une surface faite de plusieurs éléments de plafond ou de murpréfabriqués qui sont en métal ou en matière plastique et qui ont chacun la forme d'un caisson ouvert en forme de planche ou de plateau, deux de ces éléments adjacents (2, 12) sont assemblés au moyen d'un dispositif de blocage mutuel en forme de T qui est en métal ou en matière plastique et qui comprend une tige (4), ainsi qu'une surface inférieure (6) s'étendant au dessus de la tige à partir de celle-ci et se prolongeant par un coude (7) jusqu'à former une surface opposée supérieure (8), qui se termine par un bourrelet de bloquage (9) et qui est bloquée en position fixe sur la paroi (5) du premier élément (2) de façon à venir se joindre étroitement au rebord (10) du second élément par effet de ressort entre les surfaces (6, 8) et par appui du bourrelet contre la face interne de la paroi (11) de l'élément (12).In a surface made up of several prefabricated ceiling or wall elements which are made of metal or plastic and which each have the shape of an open box-shaped box or tray, two of these adjacent elements (2, 12) are assembled by means of a T-shaped mutual locking device which is made of metal or plastic and which comprises a rod (4), as well as a lower surface (6) extending above the rod from of the latter and extending by an elbow (7) until forming an upper opposite surface (8), which ends in a locking bead (9) and which is locked in a fixed position on the wall (5) of the first element (2) so as to join closely to the rim (10) of the second element by spring effect between the surfaces (6, 8) and by pressing the bead against the internal face of the wall (11) of the element (12).

Description

Interlocking Device for Joining together Ceiling or Wall Elements
The invention relates to an interlocking device for joining together pre-manufactured ceiling or wall elements, particularly elements produced from metal or plastic materials, the single element being bent and/or moulded in plank or plate-like open box form, in which an insulation material may be located, and the longitudinal walls of an elements being profiled in order to join the elements together to form a substantially whole, plane surface composed of the outward facing plane surfaces of the single elements.
US patent No. 1,738,469, US 2,478,060 and Danish patent No. 151.977 disclose e.g. so-called furring strips or rails for wall- or ceiling coverings, wherein the furring strips or rails after having been secured to a ceiling support beam are used for rigidly mounting a pre-manufactured plank- or plate ceiling, the elements forming together a ceiling cover and the single strip serving also as an interlocking device between adjacent single elements. US patent No. 4,520,607 further discloses a resilient mounting assembly, a so-called clip, for mounting of a ceiling cover of single elements or for mounting of a wall also of single elements which are inserted into the clip, and said clip being secured to an assembly beam which constitutes part of said building construction. The drawback of these interlocking devices is, however, that they maintain the elements in a direction of force perpendicular to the element surface so that said element surface does not form a whole from a constructional point of view, and consequently the single elements mutually do not abut tightly.
Finally, Danish patent application No. 3133/84 discloses a plate element having interlocking devices disposed on opposite sides, each element being provided with a bent interlocking device which is incorporated into the element wall and which may be placed in a corresponding interlocking device on the opposite wall of an adjacent plate element so as to allow the elements, by means of the interlocking devices, to be joined together in the direction of the entire element surface and independent of a mounting assembly in the building construction proper. However, the two interlocking devices require relatively complicated bends of the longitudinal walls on each element and thus demand a complicated manufacturing process of the single elements just as necessary precautions must be taken in storing, transporting and mounting of each element in order to safeguard the exposed bends.
Therefore, it is the object of the invention to provide a separate interlocking device for joining together adjacent ceiling or wall elements, and which eliminates the drawbacks mentioned above and which also exels in being simple to manufacture and simple to mount.
The object is obtained by joining together separate elements by means of an interlocking device as stated in the introductory part of claim 1 so as to form a substantially plane surface of single elements. Furthermore, for reasons of safety the interlocking device may be produced, in a manner known per se, from a fire proof material, e.g. steel, especially in case of element surfaces which are used in industrial constructions or for ship fittings.
Particular embodiments of the interlocking device are stated in claims 2 and 3.
The invention will be further explained in the following with reference to the drawing which shows partly in perspective view and partly in diagrammatic view some non-limiting embodiments of the interlocking device and the use of it.
Fig. 1 shows a perspective exploded view of two pre-manufactured ceiling- or wall elements complete with an interlocking device for joining together the elements.
Fig. 2 shows a vertical cross-sectional view of an interlocking device ("clip-profile") according to the invention.
Fig. 3 shows a vertical cross-sectional view of a ceiling or wall element which is designed to be joined together with a corresponding element by means of an interlocking device.
Fig. 4 also shows a vertical cross-sectional view of the joining together of two ceil ng or wall elements by means of the interlocking device shown in Fig. 2.
Fig. 5 shows a vertical sectional view through an interlocking device corresponding to the one shown in Fig. 2 but designed to form a notch between two adjacent elements.
Fig. 6 shows a sectional view through two adjacent ceiling or wall elements which are joined together by the interlocking device shown in Fig. 5 and with a notch between the elements.
For reasons of clarity the designations "to the left", "to the right", "up" and "down" and "vertical" and "horizontal" will be used in the following in connection with the description of the invention of both ceiling or wall elements, irrespective of the fact that in practice these designations should be used only in connection with ceiling elements.
In Fig. 1 a separately manufactured, profiled interlocking device is shown at 1 ("a clip-profile") which in joining together two adjacent ceiling or wall elements 2, 12 snaps over the longitudinal wall profile 5 on the right side of the element 2, and subsequently the wall profile 11 on the left side of the element 12 is inserted into the interlocking device in the direction towards the element 2.
In a sectional view the T-shaped interlocking device (Fig. 2) consists of a profile element 1 having a bent or doubled-back lower end made from steel, extruded aluminum or moulded plastics with a vertical stem 4 which at the top continues in a smaller, left facing surface 6, a 180" bend 7 and an upper, wider right facing surface 8 which terminates in a longitudinal bead 9 which projects downwards towards the stem 4. By way of the bend 7 and the material used a resilient effect between the surfaces 6 and 8 is obtained.
The interlocking device is designed to be attached on the right wall 5 of the element 2 shown in Fig. 3 along its entire length by inserting the small inwardly projecting flange 3, which is provided with a longitudinal bead, between the surfaces 6 and 8 of the interlocking device so as to lock the surfaces around the flange 3 and to abut the stem 4 against the inside of the wall 5, see Fig. 4. Subsequently, the left wall 11 having an outwardly projecting angularly bended flange 10 on the adjacent element is inserted into the interlocking device 1 between the downwards facing surface 8 of said interlocking device and the upperside of the inwardly projecting flange of the element 2, the surface 8 thereby being pushed upwards due to the bead 9 thus making the insertion possible. When the elements shown in Fig. 4 abut against each other through the vertical wall surfaces 5 and 11, the bead 9 in the surface 8 slides down along the inner surface on the wall 11 of the element 12 and thereby locks the two elements together, and at the same time the spring effect between the surfaces 6 and 8 of the interlocking device locks the flange 10 of the wall 11 tightly against the flange 3 of the wall 4.
In a sectional view Fig. 5 shows a variation of the interlocking device, the surface 8 here being wider and thus the bead 9 being further to the right. H indicates the height of the interlocking device which corresponds to the thickness of the elements to be joined. The greater width of the surface 8 corresponds to a greater width of the surface of the flange 10 in order for two adjacent elements 2 and 12 to be joined together under the formation of a notch with a given width A between the elements thereby creating a play in the element surface as a whole to fulfill esthetic requirements.
As shown in Fig. 6 the interlocking device 1 is placed on the wall 5 with the flange 3 in the same manner as described in connection with
Fig. 3 and 4. Subsequently, the flange 10 of the element 12 is inserted into the interlocking device between the surface 8 of said device and the upper side of the flange 3 of the element 2 until the bead 9 slides down on the inside of the wall 11 of the element 12, and due to the spring effect between the surfaces 6 and 8 of the interlocking device tightly joins the element 12 to the element 2 under the formation of the notch between the two elements.
The length of the single interlocking device may be adapted to the length of the single ceiling- or wall element in such a manner as to allow space at each end of an element for fastening of mounting assemblies for mounting of the element in the building construction and/or for the end sealing of the element. Alternatively the length of the interlocking device may constitute a fraction of the length of the single ceiling or wall element so that in locking together said elements a certain number of interlocking devices must be used for each length to be locked together in order to facilitate the locking together of long elements which may be exposed to relatively strong bending- and torsion forces during assembly, and to allow space for fastening of mounting assemblies to the building construction along the locking length.
