Definitions
- the invention relates to the problem of connection of two adjacent light building panels manufactured with flexible core (filling) and arising out of lack of strength of material when one of the objectives is to join at least two adjacent light building panels and/or connect said building panels to the wall in such a way that the observer does not see the details of the connection.
- a connection is called “hidden”.
- the fire safety of such "hidden” connection may be at issue.
- the assembly of two light building panels is performed by fitting of one edge of the first building panel to corresponding groove of the second (adjacent) light building panel whereby one achieves vertical leveling of the panels as well as good connection between adjacent panels.
- the panels are therefor fixed using removable or non removable connection (i.e. with use of screws or bolts).
- the subject of this invention is Light building panel with hidden connection and method of making of hidden connection of light building panels which solves above described technical problem.
- the essence of the invention is in covering of connecting means of an adjacent light building panel with parts of the first light building panel while at the same time load (stress) distributing elements (e.g. washers) are used to distribute the forces on the panels in event of e.g. wind.
- the distributing element enables distribution of the force onto larger surface so the allowable stresses are not exceeded.
- the solution proposed herein is the first hidden connection of panels with flexible (e.g. mineral wool) core.
- flexible e.g. mineral wool
- the essence of the invention is in design and use of appropriate distributing element which increases allowable stress at the connecting point and thereby enables suitability of hidden connection for softer and/or more flexible type of light building panel filing, i.e. mineral (rock, glass, ...) wool.
- Light building panels are building elements and are used for facades or roofs and are typically comprised of outer shell (e.g. top layer) which gives said panel shape, and of filling (also called core for the purposes of this application) which is made of insulation material which gives said panel a level of rigidity as well as limits heat transfer through it.
- Typical filling (yet by no means exclusive) of light building panel is mineral or glass wall with density up to 150 kg/m 3 .
- Light building panels can be manufactured continuously.
- the outer layer or plurality thereof can be smooth or shaped (grooved etc.).
- the connection (junction) of at least two adjacent light building panels can be covered (hidden) during assembly process to achieve aesthetic and protective results using protective covers (in this application jointly referred to as protective means).
- This protective means element serves several purposes.
- connection Due to its mechanical properties it serves as a device to strengthen the connection. At the same time it enables manufacturing of the connection whereby the outer layers (usually in form of metal sheet) of the first (e.g. left) and the second (e.g. right) panel are mechanically connected, either removably (e.g. screws) or non- removably (e.g. rivets). As a result of such mechanical connection the junction is less likely to separate during possible fire, and if it does separate, this occurs later during the fire sequence. Covered, and for purposes of this application also called hidden, connection (for purposes of this application called also junction) can also be achieved through connection through the back side of the wall (also called supporting structure) which is covered with light building panel and onto which the panels are attached.
- back side of the wall also called supporting structure
- connection using screws or bolts is described in this application as an example of connecting means, however, the connecting function can be achieved using other connecting means, so the description below holds also for other forms of connecting (e.g. rivets, adhesives, sautering etc.).
- the described connection between the outer layer (in a way of example metal sheet) of the first (for the purposes of this application also called »left «) and the second (for the purposes of this application also called »right «) light building panel provides for enhancement of mechanical characteristics of the junction.
- Higher load capacity of the junction is provided by load distributing means (such as washers) of larger surface used to distribute the load caused by the screw across larger area.
- load distributing means can be manufactured using cold deformation of metal sheet and feature strengthening elements around the edges and in the middle to enhance the rigidity of load distributing means element.
- Said element can also be manufactured of different material such as plastics.
- the junction is designed in such a way that the load as generated by the connecting means is transferred from the part of the panel in contact with load distributing means via system "lip- groove" to the rest of the panel.
- the load distributing means element can be prestressed prior to assembly so that during the tightening of the screws (or bolt) it flattens out and comes into contact with the panel with most of its surface.
- junction can be secured with other forms of removable connections, e.g. using screws.
- the covering portion of the panel finally gives appearance of smooth surface of both panels and covers position of the junction thereby contributing to nicer, more uniform view of the surface without visible signs of connection other than narrow seam between two panels in contact.
- Figure 1 shows the disassembled junction between two light building panels presenting insulation filling (1), upper (2), and lower (3) metal sheet of light building panel, covering part of the panel (4), load distributing means element (5), connecting means (6), connecting lip of the panel (8), and support construction (9, e.g. wall).
- Figure 2 shows assembled junction of Figure 1.
- Figure 3 shows load distributing means element with visible fold (7) alongside load distributing means element whereby said element is in prestressed arrangement.
- Figure 4 presents the same junction as in previous figures using additional connecting means element (10), in this particular embodiment a screw, this arrangement presenting an additional option to improve characteristics of the junction from the view of load capability and fire hazard whereby the figure shows insulation (1), upper (2), and lower (3) metal sheet of light building panel, load distributing means element (5), screw (6), support construction, connecting means (10).
- the embodiment as presented in this patent application comprises removable connecting means, in particular screw, which, at the same time, serves to connect at least one panel onto the support construction (i.e. wall). Both of light building panels are connected taking advantage of shape of connecting parts (i.e. shape-wise) whereby the junction can be disassembled if desired.
- the top layer (i.e. appropriately shaped metal sheet) of the left (2) light building panel with covering part (4) is positioned over the top layer of right light building panel and is in contact with it forming an overlap.
- Figure 4 shows an embodiment which should experience reduced risk for break of the junction during the fire due to mechanical connection of both metal sheets.
- the right light building panel can be screwed onto the supporting structure (9) during the assembly phase of both panels.
- the lip comprising of load distribution means element (5) and connecting lip (8) of the panel fits the groove of the left light building panel and exerts the pressure on the left light building panel to secure appropriate level of waterproof ability and/or ability to shape-wise connect the adjacent panels.
- the joined panels are shown in Figure 2.
- the covering part of the panel (4) thereby prevents or limits water access to the connecting spot while the connecting lip (8) prevents or limits access of water between both panels as well as air access between the panels or into the space bounded by the panels. Should one be satisfied with lower standards for sealability (displaying labyrinth-like ability) one could use less precise tools.
- top layer of light building panels (2,3) can be vary, from black or color metal sheet, to other metal materials as well as plastics and other nonmetal materials. Materials can be combined, e.g. use of metal sheet coated by plastics.
- the junction can be reinforced using reinforcing means, e.g. washers, profiles, ribs, filling, etc. to increase the strength and the load capability of said junction.
- reinforcing means element or plurality thereof is inserted under covering part (4) which therefore hides the reinforcing means.
- This reinforcement contributes to better load distribution onto larger area and therefore better load capacity of the panels whereby the aesthetic view of the panels is not significantly altered.
- the junction is in the embodiment performed with the screw (6) and additional load distribution means element (5) which also serves as reinforcement means element whereby the preferred form of said reinforcement means element is observed in figure 3.
- the load distribution means element (5) can be in the embodiment reinforced on its edges with suitable design and manufacturing during production phase of said element, e.g. with process of cold deformation of its material, preferably steel sheet.
- the reinforcement is usually achieved with formation of the fold (7) which provides for sufficient rigidity of load distributing means element and appropriate distribution of load caused by screwing of screw (6) across essentially whole areas of load distributing means element.
- the fold can be manufactured by folding (bending) of the material or using appropriate deformation method with appropriate tools (e.g. cold pressing).
- the load distributing means element (5) is slightly bent. During screwing of the screw the element is becoming flatter until the load is uniformly distributed hence the effect of prestressing has been achieved.
- the form of the metal sheet surface (2,3) of the left and the right light building panel outside of the above described system of lip and groove is left to market expectations and is not subject of this patent application. It is shown for better understanding only.
- connection means are comprised of at least one screw for connecting each of the panels onto the supporting structure whereby one of connecting means elements (10) extends through the supporting structure (9) and through connecting metal sheets of both light building panels as well as through load distributing means element (5).
