15 20 25 30 Suitably the wall panels comprise standard type construction materials, such as plaster, wood fiber boards, laminated wood, etc. The boards can be constructed as composite structures comprising one or more of these construction materials.
Each single-wall panel is connected to an adjacent panel by means of a simple locking system / a reading function. The locking function comprises a shaping of the edges of the panels according to the invention to form mutually matching wall panels. A locking element is also provided which prevents the discs from exhibiting any appreciable play in the joint, i.e. even if it is visible, the discs go against each other so that they are substantially rigidly interconnected.
A locking system according to the invention is defined in claim 2. It comprises a first and a second pair of wall panels, each panel having first and second opposite, flat surfaces, which locking system comprises a groove in the first surface of a first panel, adapted to receive a mating ace on a second disc, the groove extending parallel to and adjacent a side edge of the first disc; a ridge extending along the groove at the edge of the first disc and having a top surface located at a level below the first surface of the first disc; wherein the second disc comprises a groove and a ridge structure that mates with the groove and shaft on the first disc; and at least one support member coupled to the first disc and extending across the groove, the support member being adapted to hold the second disc in place when the second disc is connected to the first disc by means of the mating groove and ridge structures.
The locking element also functions as a spacer element to maintain the above-mentioned distance between discs. By varying the size of the spacer element, the distance between boards and thus the wall thickness can be varied.
A locking member is defined in claim 3. It comprises a body having a proximal and a distal portion; a pair of support members, each in the form of a flat element and extending at right angles from the body; fasteners on the support members for mounting on a side edge surface of each wall panel in a pair of wall panels; wherein the proximal member portion is a spacer member for defining the distance between the discs in said pair of discs; and wherein the distal portion of the body in a mounted condition extends over a groove in a first disc to which it is mounted, holding a second disc clamped to the first disc.
Finally, in a further aspect, a wall is provided, comprising at least two pairs of wall elements forming a double wall, which wall elements are interconnected with a locking element according to claim 2.
A main advantage of the wall construction system according to the invention is that one can refrain from building a complex support structure based on joists and crossbeams on which wall panels are applied such as by means of screwdriving, nailing or other methods of forming a double wall.
Additional fields of application of the invention will become apparent from the detailed description given hereinafter and the accompanying drawings which are given for illustrative purposes only and thus are not to be construed as limiting the present invention, and in which Fig. 1 schematically illustrates a double wall section constructed in accordance with the present invention. current invention; Fig. 2 schematically shows how wall panels are mounted; Fig. 3 schematically illustrates an embodiment of a locking element according to the invention; Fig. 4 schematically illustrates a further embodiment of a locking element according to the invention; Fig. 5 schematically illustrates a further embodiment of a locking element according to the invention; Figs. 6a-b show variants of the configuration of grooves and ridges on slabs in the wall according to the invention.
Detailed Description of Preferred Embodiments Fig. 1 schematically shows a wall 10 in cross section built in accordance with the present invention.
The wall comprises a set of wall panels 11a-c fastened in pairs to each other by means of locking elements 12. The locking elements have a dual function in this double-wall embodiment, namely first to clamp the panels in place and secondly to form spacers to define the wall thickness. These functions will be described in more detail below in connection with the description of the locking element itself.
The most important feature of the wall according to the invention is that it is built without a separate support structure on which wall panels are applied. Common support structures according to the state of the art are joists that extend vertically made of wood or metal, on which wall panels are applied. Instead, the wall according to the invention is self-supporting due to the locking elements according to the invention. The only support needed is a first starting rail 14 mounted on an existing wall W from which the wall to be built is to extend, and optionally a rail on the floor and a roof rail, however, the rails are not shown in ﬁ g. 1, to prevent the wall from sliding sideways on the wall surface when the wall has been put in place.
Two wall elements can suitably be connected to a starting clamp 16. A board is placed on each side of the floor / ceiling rails and the starting clamp is attached. This starting clamp is mandatorily made of sheet metal which has been bent into a shape so as to provide a receiving recess 17 with a width corresponding to the thickness of the wall element. The recessed portions are connected by means of a web portion 18 corresponding to the desired distance between the wall panels, i.e. together with the thickness of the wall elements, the total thickness of the double wall is defined when it is mounted. The life portion is arranged between the disc receiving recesses so as to form a rail receiving recess 19 which fits together with the starting rail 14 as mentioned above.
Thus, when the starting elements of the wall have been connected to the starting clamp, they are pushed onto the wall rail so that it enters the receiving recess between the wall discs. The recesses are suitably made with a width, so that the wall elements and the rail fit together tightly in resp. recesses.
However, the starting clamp 16 can be dispensed with (see below in connection with the description of the assembly procedure), and it does not in itself form part of the invention.
When the starting element of the wall has been mounted on the existing wall from which the new wall is to extend (as shown in Fig. 1), a locking element 12 according to the invention is inserted at the opposite end from the starting rail for the pair of wall elements. This locking element, of which an embodiment is shown in Fig. 1, also has a spacer function. Preferably, the locking element is provided with fastening means, such as a nail or the like, which fit into pre-arranged holes in the edge of the wall element. It could also be glued or screwed in place.
The starting element of the wall preferably has flat edge surfaces where they go against the existing wall at the starting rail. However, a locking system according to the invention is useful for connecting subsequent wall panels / elements. This locking system will now be described with reference to ñg. 2 and 3.
The locking system according to the invention comprises first and second wall panels 20a, 20b and 2la, 21b are connected in pairs with each other as shown in Fig. 2.
Each disc has the first opposite and flat surfaces, 20a1, 20a2 resp. 21a1, 2la2 (for discs 20a and 2la). The wall panels can be constructed in many different ways.
A presently preferred construction is to build each board as a layered composite structure of a gypsum board on which a honeycomb structure, for example of cardboard, is attached, and on the honeycomb board a board of masonite type is attached, e.g. . by gluing. However, many other designs are possible and the actual disc structure is not important to the invention itself.
The wall panels are generally rectangular and preferably have a height that corresponds to the height of the inner walls, and a width that makes the wall panels easy to handle. Typical dimensions could be height: 250-300 cm, width: 80-90 cm.
The locking system of the invention comprises providing a groove 22 in one of the surfaces ("first surface") of a sldva ("first disc"). Along the groove, at the edge of the disc, extends a ridge 23. This ridge has a top surface 24 which is located at a level below the first surface of the disc. The ridge thereby forms a wall 25 in the groove. On the opposite side of the groove there is also a wall 26 which extends vertically between the surface of the wallboard and the bottom of the groove. This vertical wall is used to mount a locking element, as can be seen in the left part in ﬁ g. 2 (further described below).
A similar but inverted combination of groove 22 'and ace 23' is provided along the opposite edge of the disc. By "inverted" is meant that the groove is made in the opposite surface of the disc at the opposite edge. Thus, two parallel combinations of grooves and ridge are arranged, but the grooves face in opposite directions at the disc edges.
In this way, it is possible to connect two discs by simply "hooking" the ridge on one disc in the matching recess on the other disc.
The depth of a groove in the first slab corresponds exactly to the height of a ridge on the second slab, so that when a ridge is located in a groove and the ridge goes against the bottom of the groove, the sum of the slab thickness at the bottom of the groove and the height of the ridge is equal to the slab thickness. As a result, the discs will be in the same plane when they are connected. In one embodiment, the depth of the groove is to the center of the thickness of the disc and the height of the ridge is also to the center of the thickness of the disc. As a result, the groove / ridge combinations become symmetrical, which could be advantageous from a manufacturing point of view in such a way that machining of the discs only requires an adjustment of the milling machine to manufacture the groove / ridge.
However, from the point of view of ease of assembly, ie. the moment to “hook in” the ridge in the groove be advantageous if the leading edge 27 of the ridge is slightly chamfered, as shown by ﬁ g. 1.
To pour the discs into place, ie. so that they will not move laterally (by lateral is meant the direction perpendicular to the surface of a disc), once connected to each other, as described above, a locking element 28 according to the invention is provided, of which a first embodiment is shown i ﬁ g. 2.
In general, the locking element according to the invention has a body comprising a spacer part 29 which is to be inserted between the discs and which defines the wall thickness. It also comprises a clamping part 31 connected to or integrated with the spacer part, which clamping part 31 extends over the groove (s) on the disc (s). The clamping part prevents the ridge part 23 'on a first disc from coming out of the groove in the second disc in which it has been placed to effect the reading. Finally, the locking element comprises mounting lugs 32 which extend perpendicularly from the body of the locking element and which are adapted to be rigidly attached to the disc on a wall in the locking groove.
In this first embodiment, the locking element comprises a preferably rigid body having opposite flat and parallel surfaces, where the thickness of the body between said surfaces corresponds to a desired distance between the wall panels. By “rigid” is meant that it must not be easy to compress, as it would then not meet the requirement of being a stable spacer element. It could be made of a relatively hard but resilient material, such as rubber or the like, but preferably it is made of metal, such as aluminum, or a rigid cast polymer material. In a most preferred embodiment, the locking element is manufactured from a tube with a rectangular cross-section or at least a cross-section which has two parallel sides. 10 15 20 25 30 The body of the locking element has two ends, a proximal end which is the part of the body which extends to the left, i.e. into the space between the discs as shown in ﬁ g. 2, and a distal end, which extends to the right in ﬁ g. 2, and which forms a squeezing and reading part of the body.
The proximal end of the body, which is to be inserted between the wall panels, forms a distance to separate the wall panels to the desired extent.
In an alternative embodiment, schematically shown in Fig. 3, the body 33 is formed as a beam-like structure having a number of ridges 34 connected by means of webs 35. The webs extend in the same plane as the discs, and the flanges extend perpendicular to the webs. The width of the flanges defines the space between the discs.
Other configurations of the spacer part are possible and are within the scope of the invention.
The distal end of the body constitutes the actual means for clamping a second disc in the groove belonging to a first disc.
Arrays 32 (cf. ﬂ g. 2) are arranged on the body, one on each side of the body and they extend at a right angle from said flat and parallel body surfaces.
These ﬂ grooves will abut the above-mentioned vertical walls in the grooves in the discs in the assembled state and are used to attach the locking element to the discs.
In the embodiment of the locking element shown in ﬁ g. 2, the clamping member includes a resilient portion 28 which provides additional clamping force when the discs are in the assembled condition. Hair, the resilient portion may be curved as shown so as to be easily bent away when attempting to insert the ridge at the edge of a disc into the groove belonging to another disc. On the other hand, the resilience should be such that a clamping force is applied to the disc when it is placed on the groove belonging to the second disc. In particular, the resilient portion comprises two resilient tongues 31 which are biased so that they extend slightly out of line towards the respective track. In order for a disc to be easily inserted into the groove, the tongues are bent back outward (curved) from the grooves at the distal end of the tongue, so that the ridge of the disc is guided into the groove and forces the tongue outwards during insertion. When the ace of the disc is in place in the groove, the tongue 31 will exert a force on the disc which effectively prevents it from coming loose from the groove laterally.
In a further embodiment of the locking element 40, the clamping part comprises a resilient portion 41, formed by folding or folding metal sheet. This is shown schematically in ﬁ g. 4. The pleated configuration makes it possible to easily bend the tongue when trying to insert the ridge at the edge of a disc in the groove belonging to another disc. On the other hand, the resilience should be such that a clamping force is applied to the disc when it has been put in place in the groove in the second disc.
In a further embodiment, the locking element 50 is designed as shown in ñg. 5.
Here, the clamping portion is a rigid clamping member 51. Instead of actually clamping the disc, the distal portion is rigid and acts as a support to prevent the disc from coming out of the groove.
To attach the locking element to the discs, various methods and means can be used. They could be glued, nailed or screwed in place. However, the preferred way is to provide the flanges with pins or the like extending from the ﬂ axes. Suitably there are holes provided in the groove wall in which the pins fit tightly in order to hold the locking element in place during mounting of the wall panels to form a complete wall. In addition, the locking element, when applied as described, will hold the boards together and thereby clamp them against the floor or wall. the speech rails.
A process for mounting a wall in accordance with the invention will now be described. 10 15 20 25 30 10 The first step is to apply a rail which extends vertically to an existing wall from which the new wall is to extend to form a new inner wall. This rail has a width corresponding to the desired space between wall panels forming a double wall.
Instead of rails, it is possible to apply segments of a rail or even simply blocks at different points along the existing wall in order to form attachment points for the new wall. However, a fully extended rail is preferred from a stability point of view. The floor and ceiling rails are also installed.
Then two wall panels are connected together with at least two starting clamps with a design as described above. It should be noted that preferably the first two wall panels do not have a groove and ridge structure arranged at the edge to be applied to the existing wall. Instead, these boards have flat edge surfaces so that they fit snugly against the inconvenient wall without the need to hide any unsightly traces.
The "starting segment" of the double wall is pushed over the rail on the existing wall so that the rail enters the rail-receiving recess in the starting clamp.
In a simpler alternative embodiment, the discs are simply attached to the wall rail by screwing one at a time, and when they are applied, the locking element is connected to the disc pair as described.
As indicated above, there is optionally, but preferably, also a rail arranged on the floor to stabilize the double wall laterally. This rail could be substantially identical to the rail on the wall on which the starting segment is applied.
Thus, the floor rail would also fit exactly into the space between the wall panels. The starting segment of the double wall would then suitably be placed over the floor rail and pushed against the rail on the wall until it has been placed correctly. Furthermore, a similar or identical rail is preferably provided in the roof to provide additional stability to the wall structure. At opposite ends of two discs, there are suitably two or more reading elements according to the invention and described above, applied as described.
When the first two discs have been mounted on the wall as described, a pair of locking elements, as described above, are applied to the discs.
With reference now to ﬁ g. 6a-b, the actual profile of the locking parts of the individual wall panels will be described.
Fig. 6a shows an embodiment where the groove and ridge structure is asymmetrical to such an extent that the groove in the first (left in ﬁ g. 6a) disc is shallow, ie. it extends downwards only a part of the thickness, less than half the thickness of the disc. The matching ridge on the other (to the right in ﬁ g. 6a) is correspondingly small, so that when the discs are connected, the disc surfaces will be in the same plane (indicated at the far right in ﬁ g. 6a).
Fig. 6b shows an embodiment where the groove and ridge structure is symmetrical to the extent that the groove in the first (to the left in ﬁ g. 6a) the disc extends downwards exactly to the middle of the thickness of the disc. The matching ridge on the second (to the right in ﬁ g. 6a) the disc corresponds exactly to the groove in the first disc, so that when the discs are connected, the surfaces of the discs will also in this case be in the same plane (indicated at the far right in ﬁ (6b).
Any combination of depth of groove and height of ridge can be used as long as the boards are in the same plane when mounted.
