Definitions
- the invention relates to a method for producing Sub-roof panels according to the preamble of claim 1.
- roof panels are used for the construction of thermally insulated Roof structures used, the insulation layer for example from mineral fibers between the roof structure and the roof covering is.
- the decking sheets wear the roof covering or roof skin, for example the bricks, while the spacers prevent the insulation layer pressed together under the influence of the roof load becomes.
- a generic comparable element for a heat and sound-absorbing sub-roof is, for example, by DE-A 34 37 446 became known. With this element is the insulation layer however as a section directly under the decking plate glued. This creates high manufacturing costs and Client cannot choose between different at will Choose thermal insulation materials. In addition, the finished Insulating elements have a high transport and storage volume. Also the Disposal causes considerable problems with glued Insulation layer, if this e.g. made of mineral fibers, the cover plate but made of wood fibers.
- the insulation layer is not at all with this method more glued to the decking plate, but only on the Construction site loosely laid on the supporting structure.
- the only one consisting of the cover plate and the spacer Sub-roof panels are manufactured by the manufacturer after applying the adhesive, or immediately after the actual gluing process stacked in such a way that there are always several decking panels lie flat on one another, or the ones assigned to them Spacers are staggered next to each other in steps. In this stacking state, which is extremely space-saving, the adhesive bond is then finally cured.
- a special rationalization effect can be achieved if both a cold glue and a Hot melt adhesive (hot melt) is applied and if before Stacking a contact pressure is exerted on each spacer.
- hot melt Hot melt
- In the sub-roof area are preferred for adhesive bonds waterproof cold glue used, which are cold curing, whereby however, a contact pressure over the entire curing time is required.
- the pressure-free adhesive and quick curing Hot melt adhesives have the disadvantage that the Adhesive connection under the very high temperatures in foil-packed Stacking or loosening directly under the brick layer or postpones.
- the combination of cold glue according to the invention and hot melt adhesive now enables immediate Fixing the spacers, but only a very short time Pressure is required while the cold glue is in the stack hardens. In this way, production can also be special can be easily automated.
- the adhesive is preferred for automated production only applied to the cover plate. It can a medium strip of hot melt adhesive on the contact surface and at least one outer strip on each side of it Cold glue can be applied. This creates a stable Compound, which is also in a plasticization of the Hot melt adhesive can not move.
- the adhesive application and the pressing of the spacers preferably takes place at separate workstations, the Covering panels on a conveyor to the work stations be transported.
- the level of automation such a high number of work cycles per unit of time to reach.
- further workstations may be arranged, e.g. a separate feed station, a discharge station or a straightening station for precise positioning of the spacers.
- the spacers can be glued to the Covering plates but also directly when building the stack respectively.
- This method of production is particularly suitable for a production with a relatively low degree of automation, just a few simple tools required are. In such a case, the Adhesive advantageously applied only to the spacers.
- a particularly space-saving and also with regard to one Pressing advantageous stack can be achieved if the flat covering sheets one on top of the other Stacks each form a group and when a stack is made several groups is built, two groups each form a group in which the spacers of the one Group turned upside down against the cover plates of the others Group are directed. Despite the lateral staggering of the In this way, spacer bars can be used for numerous under-roof panels stacked on top of each other without the whole Stack gets an excessive width.
- the gaps between the exposed end faces of the spacers one Group and the opposite cover plate of the neighboring Group are filled out by web elements, which are cut out like a staircase so that each exposed one Front side rests on a cutout.
- web elements which are cut out like a staircase so that each exposed one Front side rests on a cutout.
- the stacks are advantageously made by means of those remaining on the stack Straps held together and pressed together.
- Such straps are made of metal or plastic Known and common for holding general cargo together. They can be tensioned so that one for one Adhesive connection sufficient contact pressure is achieved.
- the stacks can, however, until the final hardening of the Adhesive also pressed together with at least one detachable drawstring with straps remaining on the stack and detachable drawstrings also used together can be.
- the contact pressure also apply to the stack using a press.
- a wood fiber hardboard is preferably used for the cover plate used with a smooth and with a rough side.
- the spacer also consists of a fibreboard of lower density, being so on the smooth side of the decking sheet is glued to that Fibers of the spacer essentially in one plane in the run at right angles to the decking plate.
- For wood fiber boards Because of the manufacturing process, there is a certain one Orientation of the fibers that are used on the spacer can be that the fibers stand upright if possible run at right angles to the decking panel. In order to the greatest possible pressure resistance is achieved.
- the smooth one Side of the wood fiber hardboard provides a good contact area for the glue connection, while the rough side is an inspection of the sub-roof during assembly.
- Alternatively could also be another plate, e.g. a bitumen Fibreboard, a chipboard or even a board a mineral material can be used.
- the Spacer could e.g. from waste paper, solid wood, cork, etc. consist.
- a sub-roof panel 1 consists in essentially from a rectangular decking plate 2 to which on a long side 5, a spacer 4 is glued.
- the Cover plate consists for example of a hardboard with a thickness of 3.5mm to 5.0mm.
- the plate has a smooth side due to the manufacturing process, on which the Spacer 4 is glued and a rough side with a Grain 10, which of the roof covering, not shown here turned towards.
- the spacer 4 also consists of a fibreboard, or it is cut from such a plate, whose density is lower than that of the cover plate 2. As indicated in Figure 1, the spacer is so glued that the individual fibers essentially in are oriented at right angles ⁇ to the cover plate 2. In order to a particularly high compressive strength is achieved and the Allows the use of a relatively light and soft insulation material.
- the spacer 4 also does not extend over the entire long side 5, so that a lateral overlap area 6 is formed for the decking plate.
- the insulation layer 3, for example made of mineral wool, plant fibers, etc. in Figure 1 is only for completeness shown. This layer of insulation is not firm with the cover plate 2, but is separately provided by the customer Cuts or rolls delivered and directly when building the Posted under roof. The width of the insulation strips is dimensioned so that on the spacer 4 facing longitudinal side forms a longitudinal overlap area 7.
- the sub-roof panels 1 built in rows from the eaves to the ridge. You are lying on a view formwork 9 by the Rafters 8 is worn. After striking an insulation layer 3, this in turn is from a sub-roof panel 1 covered, with the individual plates scaly overlap. The attachment is done by mounting Counter battens with special nails or screws that go into the underlying rafters 8 are driven. On this one not shown counter battens and roof battens Roof skin consisting of bricks, sheet metal, etc. laid.
- Figures 3 and 3a show a highly schematic semi-automatic Production in which the spacer bars are already in place stacked.
- a conveyor belt or chain 11 moves in the direction of arrow a and transports individual cover plates 2 to different workstations. They pass at least one glue application station 12, an adhesive station 13, a pressing station 14 and a removal station 15. Before the glue application station 12 could be another separate feed station can be arranged.
- the decking sheets are provided as a stack 16 at the beginning of the conveyor belt.
- the individual spacer webs 4 rest as a stack 19 the gluing station 13 ready.
- a cold glue dispenser 17 a double track of cold glue 23 (FIG. 3a) on the contact surface applied.
- a hot melt adhesive dispenser 18 a middle trace of hot melt adhesive 22 is applied.
- a spacer 4 is placed on each contact surface coated with adhesive and placed exactly positioned.
- the sub-roof panels 1 from Conveyor belt 11 removed and on a stack 21 on the way described in more detail below for the final curing of the cold glue stacked.
- Figure 4 shows an alternative production option with identical workstations as in the exemplary embodiment according to Figure 3.
- the same components therefore have the same Reference numerals.
- the feed is not carried out on one Conveyor belt, but on a turntable 25, which is cycled rotates about a central axis 27.
- the adhesive dispenser 17 and 18 must therefore be moved on a feed path 26, to apply the traces of glue.
- the stack 21 is placed on suitable supports 34, so that it can be lifted later with a forklift.
- a stop frame is used on one long side as stop aids 35 and a stop side wall on one end face 36.
- the stop frame 35 can be after the finished construction Remove the stack to make strapping easier.
- the stacking is carried out in such a way that several cover plates each 2a to 2f lie flat on top of each other.
- the assigned to them Spacers 4a to 4f lie side by side and are staggered like stairs. Since the graduation in Not continued arbitrarily with regard to the stack width the stack is divided into several groups 28, 28 ' divided. Two successive groups each form a pair of groups 29. The two groups of a pair are reversed in each case, i.e. rotated by 180 °, facing each other.
- the spacers 4a to 4f of group 28 are thus directed against the first cover plate 2a of group 28 ', while the spacers 4a 'to 4f' of the reverse staggered second group 28 'against the top cover plate 2f group 28 are directed.
- a second follows Group pair 29 ', which in turn has the same structure as that first group pair 29.
- groups of Six sub-roof tiles each shown. That number, as well however, how the number of group pairs can vary depending on the application vary.
- Figure 6 shows such a web element made of sheet steel, the to achieve sufficient lateral stability Bend 31 has. Width and height of the individual sections 32 correspond to the width of the individual spacers 4 and the height difference in the graduation.
- Spacer blocks 33 inserted to deflect the decking plates to prevent.
- a power transmission for pressing purposes is not necessary here. After pressing and The web elements can also harden the adhesive connections 30 removed and replaced by spacer blocks 33 become.
- Figure 7 shows a view of the long side of a stack 21, four web elements distributed over the entire length 30 are inserted per group pair. At two places the stack is surrounded by a strapping 39 and is compressed and stabilized by it. The strapping are not directly on the sub-roof panels, but develop their pressing force via a lower square timber 37 and an upper square timber 38. The two strapping are sufficient for the later transport of the stack. However, to at least during the curing time of the adhesive Generating sufficient contact pressure is in the middle range a releasable tensioning strap 40 is applied, which by means of a Clamping device 41 brought to a desired clamping force can be.
- the stop frame 35 has already been removed in FIG to make it easier to put on the straps and straps. After removing the strap 40, the whole Stack still be surrounded with a shrink wrap, which protects the roof tiles from moisture.
