Definitions

  • Building sealing means any case of sealing on a building, e.g. sealing in the roof area or in an area that can later come into contact with water and/or soil (e.g. basement).
  • the present application therefore has the task of providing a solution with which a building seal can be produced safely and more cost-effectively, taking into account the known technical rules.
  • a molded part for building sealing is intended and suitable for being attached to a building.
  • the molded part When mounted on the building, the molded part has at least three surfaces, each of which lies in a separate plane and the planes intersect at an intersection.
  • the molding can be flexible, which makes cultivation easier.
  • the intersection point can also be understood as a cutting area, since the physical design does not result in any sharp edges or corners due to the material of the molded parts.
  • intersection point can also be an imaginary point, since in the actual design of the molded part the material of the molded parts does not extend to the intersection point, but ends beforehand, such as with a truncated cone or a truncated cone surface, but the planes in which the surfaces lie intersect at this intersection. In other words, the intersection point can also lie outside the molded part.
  • a molded part for building sealing has a conical shell shape.
  • the cone shell shape is fundamentally to be understood both as a three-dimensional body (cone or conical body without a bottom surface) and in its development (spreading out the surface on a plane).
  • the cone shell shape can have the advantage that the molded part can be easily manufactured. This can also have the advantage of simplifying installation on a construction site or attaching the molded part to the structure.
  • a molded part comprises at least a first surface molded part.
  • the surface molding at least partially comprises a flexible sealing membrane. This can have the advantage that the molding is easy to produce.
  • a second surface molding is arranged at least at the intersection point in a molded part. This can have the advantage that the molded part is more stable and/or seals better.
  • a liquid sealant is arranged at least at the intersection of a molded part. This can have the advantage that the molded part is more stable and/or seals better.
  • a molded part comprises at least one joining seam. This can have the advantage that the molding is easy to produce.
  • the planes of a molded part are perpendicular to one another. This can also have the advantage of simplifying installation on a construction site or attaching the molded part to the structure.
  • a molding includes an insert.
  • the insert can be an internal and dimensionally stable insert.
  • the insert can include at least one of polyester fabric, glass fabric, glass fabric, fleece, wire mesh.
  • “Inside” means that the insert is covered by at least one layer on each of the two surfaces. In other words, the insert is at least largely enclosed by the material of the layer through which the surfaces are formed.
  • the insert can be overstretched, for example when installing the molded part, the insert can be specifically overstretched and the insert can therefore be torn, for example if desired. This means that the molded part can be adapted to the respective building subsoil or building shape.
  • the insert ensures that the molded part is dimensionally stable under changing environmental conditions, particularly with regard to temperature changes and humidity.
  • the insert can be a network of non-metallic fibers. This network can have fibers that run 90° to each other. The fibers can be connected at the crossing points, for example welded or glued. The fibers can be glass fibers. If the insert or net is overstretched, fibers in the net can tear and/or the connections at the crossing points can fail. For example, a fiberglass network can tear and/or the connections come loose at around 5% or more.
  • the dimensions of the insert are specifically chosen so that over-stretching is possible, as known inserts (nets, expanded metal) are not supposed to tear.
  • a molded part further comprises at least one lamination.
  • This can have the advantage that the building sealing can be carried out more easily and reliably and the lamination forms a non-positive and waterproof connection with the subsurface.
  • the at least one lamination can be arranged on the side of a first surface molded part which faces the building when the molded part is in an installed state.
  • the lamination can include at least one of a polymer-modified and self-adhesive bitumen layer, self-adhesive layers based on butyl and acrylate, hot melt, PE, PP or their respective mixtures, thermoplastic layers based on polyolefin.
  • the molded part lamination can be converted into a liquid (low viscosity) state by the action of heat and made to adhere to the substrate.
  • a molded part comprises at least one of polymer bitumen, plastic (PVC, FPO, EVA, CSM, styrenic block copolymers, among others), elastomers (EPDM, butyl, NBR, ACM, among others).
  • a method for producing a molded part for building sealing further comprises the step of applying a second surface molded part at at least one intersection after the joining step.
  • a method for producing a molded part for structural sealing further comprises the step of applying a liquid sealant to at least one intersection point Step of joining. This can have the advantage that the molded part is more stable and/or seals better.
  • a method for producing a molded part for building sealing includes forming the first surface molded part in a cone shape or cone shape when forming the first surface molded part.
  • a method for building sealing further comprises the step of preheating a lamination on a molded part before or during the step of creating a seal in corner regions of the building.
  • This can have the advantage that the structural sealing is simpler, more reliable and quicker to produce.
  • the lamination is converted into a liquid (low viscosity) state by the action of heat and is made to adhere to the substrate. This can have the advantage that the lamination forms a force-fitting and waterproof connection with the substrate.
  • a conical surface or the molded part is to be understood as cone-shaped, whereby the cone surface is not to be understood in the mathematically precise sense, but the cone surface can have different shapes, as long as it results in a hollow one that is open at least on one side
  • This results in a tapering body opposite this side as is known, for example, from cones or school cones or ice cream cones.
  • This body can, but does not have to be, tapered; it can also be the lateral surface of a Act as a truncated cone (outer surface of a cone), whereby here too truncated cone is to be understood broadly in the sense of the above statements.
  • this body or the molded part does not have to be symmetrical (eg rotationally symmetrical).
  • FIG. 1 a schematic representation of an embodiment of the application is shown.
  • the molded part 10 comprises a first surface molded part 20 and a second surface molded part 21.
  • the first surface molded part 20 comprises a first surface 11, a second surface 12 and a third surface 13.
  • the first, second and third surfaces are 11, 12 and 13 from the first surface molding 20 includes.
  • the molded part has a conical shape or is cone-shaped and tapers to an intersection point S, which also represents the tip of the conical shape or cone.
  • the Figure 1 shows the molded part 10 in a mounted state, for example on a building.
  • the molded part shown is used to seal a so-called inner corner on a building.
  • the molded part 10 thus extends into the drawing area or sheet plane, the intersection point S is deeper in the drawing plane than the edge shown on which the reference number 20 is marked.
  • the first, second and third surfaces 11, 12, 13 are perpendicular to one another.
  • the first, second and third surfaces 11, 12, 13 each lie in a plane E1, E2 and E3. These planes E1, E2 and E3 also intersect at the intersection S and are perpendicular to each other.
  • the second surface molding 21 is applied to the first surface molding 20.
  • the second surface molding 21 is shown in dashed lines, since it is applied to the back, ie the side facing the building. However, this is optional. It could also be visible on the as in the Figure 1 shown side of the molded part 10 can be applied and furthermore a further surface molded part could be applied, so that a reinforcement in the area of the intersection S is applied on both sides.
  • a liquid sealant 30 is also applied in the area of the intersection point S. This can cover the second surface molding 21. The liquid sealant 30 can also be applied if no surface moldings are present.
  • the molded part 10 has a joining seam 40 between the first 11 and second surface 12.
  • the molded part 10 comprises the first and second surface molded parts 20 and 21, whereby the two surface molded parts 20 and 21 are flat molded parts in their development and the molded part 10 acquires its three-dimensional extent largely by folding in and joining the first surface molded part 20.
  • the joining takes place, for example, on the joining seam 40, but any other placement of the joining seam 40, several joining seams or even a seamlessly shaped molded part is conceivable; this applies across the entire disclosure area.
  • the second surface molding 21 is also manufactured in this way and attached to the first surface molding 20.
  • the joining area between the first and second surface moldings 20 and 21 can be additionally sealed with a liquid sealing compound 30.
  • the joining seam 40 can be additionally sealed with liquid sealant 30.
  • Figure 2 shows another view of the molded part 10 from the Figure 1 .
  • the Figure 1 shows the molded part 10 attached to a building or in its installed state.
  • Figure 2 represents the (pointed) bag shape or conical shape of the molded part 10.
  • the three surfaces 11, 12 and 13 are deformed inwards and the molded part 10 therefore extends less far to the edges of the sheet Figure 2 in comparison to Figure 1 .
  • the intersection point S is in the representation of the Figure 2 not visible, but sticks out like that Figure 2 into the leaf plane.
  • the joining seam 40 can also be seen. At each joining seam, the material of the sections to be joined can be designed to overlap, resulting in a stable joint.
  • Figure 3 shows a further embodiment of the application, a molded part 10 which is intended for sealing external corners in a mounted or installed state on a building.
  • a molded part 10 which is intended for sealing external corners in a mounted or installed state on a building.
  • the representation of the Figure 1 include three levels E1, E2 and E3 respectively the first 11, second 12 and third 13 areas. These in turn intersect at an intersection point S.
  • the embodiment of Figures 1 and 2 is the embodiment of the Figure 3 not conical or cone shaped.
  • the embodiment shown has two joining seams 40.
  • the arrangement of the joining seams or the shape of the first surface molding 20 and possibly the second surface molding 21 is arbitrary, as long as the three levels E1 to E3 result in an installed or mounted state of the molding 10 , which intersect at the intersection point S.
  • at least one joining seam 40 can be arranged on the second surface molding 21 and connect to the first surface molding 20.
  • FIG 4 shows a schematic cross section through a flexible sealing membrane 50.
  • the flexible sealing membrane 50 comprises a TPE layer, which represents the visible side in an installed or mounted state of the flexible sealing membrane 50.
  • An insert 60 is inserted into an EPDM layer 90.
  • the insert comprises a known glass fabric, so only the fibers that run perpendicular to the plane of the sheet can be seen in the sectional view.
  • the weight per unit area of the glass fabric is greatly reduced compared to a conventional sealing membrane.
  • the insert of a conventional sealing membrane can be have a basis weight of, for example, 50g/m 2 and the insert 60 of the molded part 10 or the flexible sealing sheet 50 can have a basis weight of, for example, 16g/m 2 .
  • a range for the basis weight of the insert 60 of the molded part 10 or the flexible sealing membrane 50 can be between 10 and 180 g/m 2 .
  • the insert can be a fiber network.
  • the insert can tear at 5% or more stretch and/or connections at fiber crossings can come loose (see above).
  • the present application is not limited to molded parts with the above structure. Any combination of materials and arrangements are possible, with or without insert 60.
  • Figure 5 shows a flowchart for a method for sealing a structure using one of the above-mentioned molded parts 10.
  • a step S10 at least one sealing membrane is applied in a known manner to the respective surfaces of a structure to be sealed.
  • a molded part with the intersection point S is aligned with a corner region of the structure to be sealed.
  • a molding 10 for inside corners as in Figures 1 and 2 To see, the molded part 10 can be seen, for example, as in Figure 2 shown cannot be placed fully unfolded in the corner.
  • a lamination 70 is preheated on the molded part 10. This allows the quality of the connection to be increased in the following step S40 when attaching it to the structure.
  • the attachment depends on the basic material pairing between the seal applied to the surfaces in step S10 and the material of the molded part 10. Conventionally, the molded part 10 is connected to the seal from S10 by applying heat and pressing. But of course adhesives or liquid sealants can also be used (additionally or exclusively).
  • a manufacturing method for a molded part 10 is disclosed.
  • a step S10 a first surface molding 20 is produced. This is typically cut out of a flexible roofing membrane, which is used to seal the surfaces (e.g. S10 in Fig. 5 ) fits.
  • a second surface molding 21 is produced.
  • the second surface molding 21 can be made, for example, from a material that matches the material of the first surface molding 20, so that the two surface moldings can be processed together in the best possible way.
  • the first surface molding 20 is shaped. Since in step S10 the first surface molding 20 is usually made from a flat piece of flexible roofing membrane, the first surface molding 20 must be brought into a three-dimensional shape.
  • a step S40 the shaped first surface molding 20 is joined so that it retains the shape produced in step S30.
  • This can be done, for example, by tabs that are formed in the area of the above-mentioned joining seam 40. These tabs can have an overlap or width of 20 to 80 mm.
  • the second surface molding 21 is applied to the shaped and joined first surface molding 20. This can be done, for example, in the area of the intersection S and/or along the one (or more) joining seam 40.
  • the second surface molding 21 can be applied both to the side of the molding 10 that faces the structure in the installed state or to the side of the molding 10 that faces away from the structure.
  • Several second surface moldings can also be produced and applied, for example from both sides mentioned above.
  • liquid sealant 30 is applied to the second surface molding 21 applied to the first surface molding 20. This can be done with some overlap, so that an area around the second surface molding 21 is covered.
  • the liquid sealant 30 can be any low-viscosity, e.g. brushable or sprayable sealant.
  • the first and second surface moldings 20 and 21 can also be produced by a suitable manufacturing process, so that steps S10/S30 and S20/S40 are carried out in combination, as would be possible, for example, with an injection molding process or with 3D printing.
  • the entire molded part 10 can also be produced using such a manufacturing process.
  • Steps S10 to S60 can be applicable, for example, for manual production of a molded part 10.
