Definitions

  • the invention relates to a connection at the longitudinal joint of profiled roof elements according to the preamble of claim 1.
  • This bend has the disadvantage that the roof elements cannot be easily pushed horizontally against one another on their support during assembly. Rather, they must be guided diagonally downwards from above. Such a movement is very difficult with the roof element, which is usually over 10 m long, hanging on a crane and can only be carried out with many helpers and aids. If the sloping downward area of the covering sheet metal is only bent down after assembly, this is difficult to carry out over the long length. Irregularities are visually disruptive and the paint is often damaged.
  • EP-A-0 051 351 there is also an element which can be used for roofing, in particular shown in FIG. 16, which can be brought into the mounting position by pushing horizontally against one another, so that the mounting is relatively easy to carry out.
  • This element has the disadvantage that the upper metallic surface boundaries of the plates to be joined butt directly against one another, so that only minor manufacturing errors can be permitted and the connection can be compensated for. This makes the production extremely expensive. Due to the fact that the foam does not always expand with the same volume increase during curing, this can never be carried out with narrow tolerances. The connection is also not mountable if one of the edges is only slightly bent during transport.
  • Another disadvantage is that, in order to maintain closer tolerances, the elements within the entire joint are closed off by fixed boundaries, the installation of which is expensive and which, as thermal bridges, have a negative influence, which also leads to condensation with regard to air humidity and, as a result, to corrosion and premature Wear leads. It is the object of the invention to avoid these disadvantages, to create an easy-to-assemble connection which can be produced with extremely large tolerances, which is very tight, has a heat transfer value which is not higher in the joint area than in the rest of the element and which is also extremely easy to do is to be installed and where the joint is only so slightly visible on the inside that it does not interfere with the appearance.
  • the manufacturing tolerances of the roof elements can be chosen larger the wider the resilient seal between the elements is chosen.
  • a very wide, only one porous Foam existing seal has the disadvantage that the water vapor in the room air diffuses through it and then condenses when it comes into colder outer areas of the seal. Cold areas start around the middle of the seal and extend to the outer boundary of the roof element. In winter, the resulting condensation can cause the entire seal to fill with water like a wet sponge.
  • a vapor diffusion barrier is installed in such a way that the joint on the inside is closed off by tongue-like projections which are nested one above the other and which are themselves covered by the metallic cover layer, which is known to be impermeable to water vapor.
  • the tongue-like projections do not interfere with the assembly, since they are arranged one above the other at a short distance in height. Their front boundaries slide over one another to the extent that the roof elements compress the seal in a resilient manner during assembly. Due to the difference in height, there is normally a gap between the tongue-like projections between the upper side of the lower projection and the lower side of the upper projection. Through this gap, water vapor can still diffuse towards the seal, albeit to a very small extent that is not harmful to practice. This gap normally disappears completely when the screw for fastening the roof elements is tightened, because then the pressure of the entire roof element in the joint area compresses somewhat in terms of its thickness.
  • This type of diffusion barrier is also effective when there is only a tongue-like projection that covers the wide seal.
  • the overlap is particularly good when the tongue-like projection protrudes into an indentation on the other roof element and the degree of protrusion compensates for the deflection of the thick seal and manufacturing inaccuracies.
  • the invention is explained using the example of an inclined upward joint. It can also be used for vertical joints. In the case of vertical joints, it is appropriate if one or two fastening screws run vertically next to the joint outside the area of the elastic seal through the roof elements.
  • Inclined joints have the advantage that the hole for the fastening screw runs largely outside the seal and can be drilled there more easily than in the strongly resilient seal.
  • the hole for the fastening screw which must be drilled on the roof at the construction site, can be drilled particularly easily if it starts in the gap at the top, passes vertically through the easily drilled foam of the roof element 1 and below in the gap that the indentation one element 1 forms with the tongue-like projection of the other element 2, passes.
  • a recessed groove in the form of a bead is formed in the sheet above the gap.
  • the highly elastic seal located between the roof elements can also, contrary to the seal shown in the figures, consist of several, e.g. B. consist of two parts.
  • the seal may be missing entirely or consist of a plastic foam that is not highly elastic, but is easily compressible.
  • thermal insulation materials are particularly inexpensive.
  • the disadvantage that a narrow gap can form in this case because of the low elasticity is irrelevant in terms of thermal insulation, since no significant convection of the air is formed in the narrow gap. If the cheap less elastic plastic foam is sealed, then the joint is sufficiently sealed.
  • the grooves for snapping the cover covering the joint area are somewhat higher than the level of the upper metallic cover layer, so that this does not occur even when there is little rainfall get wet, which significantly extends the durability of the roof element.
  • the invention is explained in more detail using an exemplary embodiment. 1 to 3, the individual steps of the assembly are shown.
  • the right side of the connection is shown from the roof element 1 and the left side of the connection is shown from the roof element 2.
  • the roof elements 1 and 2 are first placed on the rafters or other fastening beams or beams. With roof elements over 10 m long, this is usually done with a crane.
  • the roof elements 1 and 2 deposited in this way are in accordance with FIG. 1 with a space between them. It is then, for. B. moved by an assistant, the roof element 1 to the roof element 2 or vice versa, so that both roof elements, as shown in Fig. 2, touch.
  • the made of a very soft, resilient material, e.g. B. foam, existing seal 3 is pressed much more strongly in the lower area than in the upper area.
  • the two roof elements 1 and 2 are connected by a screw connection. For this purpose, the plate 4 is pressed down by the screw 5.
  • the sheet 4 has obliquely downward side parts 6 and 7, these are pressed against obliquely upward extending parts 8, 9 of the metallic cover layer 10. Due to the oblique design of the support surfaces, the roof elements 1 and 2 are pressed even more firmly against one another and the seal 3 is also pressed together somewhat more strongly.
  • the joint and the screw connection are protected against rainwater by the cover 11.
  • the cover 11 hooks resiliently into a bead 12 for its attachment. In strong winds, raindrops can also be driven through the joint 13 to the screw connection. It is therefore important that the joint 13 is sealed by a likewise highly elastic seal 26. This seal can be attached at any point in the joint. It is particularly advantageous if the seal 26 on the upper part the joint is attached. In the example in FIG.
  • the seal 26 also serves as thermal insulation for the cover 11.
  • the parts 15 and 16 which project upwards are also in the metallic cover layer near the edge of the roof elements 10 molded. It is very important that the troughs 17 and 18 are located between the upstanding parts. In the event that z. B. the seal 26 was damaged during transport, water penetrated is discharged through the troughs, which have a slope according to the roof pitch after installation. It is advantageous if the upwardly projecting parts 15 and 16 project beyond the parts 8 and 9. This protrusion is not necessary if the cover 11 is slightly curved to achieve the necessary height for the screw head.
  • the hole for the screw 5 is only drilled when the roof elements 1 and 2 have been placed, as shown in FIG. 2.
  • the foam core 19 of the foam can be easily drilled through. It is advantageous that the screw 5 passes through the gap 21 which is formed by the tongue-like projection 22 and the indentation 23. So that the drill finds this location more easily, the sikke 24 is molded into the lower metallic cover layer 20.
  • the majority of the joint 25 is directly delimited by the foam core 19. It is easier to glue the seal 3 to the foam core 19 if the joint is straight and level.
  • the seal 3 is poorly suited for drilling through, so it is advantageous if the joint 25 extends obliquely upwards.
  • the seal 3 can also be completely absent in the upper region of the joint 25, so that it does not need to be drilled through.
  • the seal 3 does not need to be compressed in the upper area, it serves only for thermal insulation there and is only intended to prevent air convection, while in the lower area the strongly compressed seal is also intended to largely prevent vapor diffusion.
  • Small beads 27 are advantageously molded into the lower metallic cover layer 20 for reinforcement. These beads run at an angle of 90 ° on the connection or on the connection Add 25. This stiffening causes the forces required to compress the seal 3 to be conducted in its lower region.
