Description

The present disclosure lies in the area of building sealing and relates in particular to a molded part for building sealing and its

Manufacturing. Structural waterproofing refers to any case of waterproofing on a

Building understood e.g. seals in the roof area or in an area that can later come into contact with water and/or soil (e.g. basement).

[0002] When sealing buildings, particular attention is paid to sealing corner areas of the building. Until now, sealing these areas was largely characterized by manual work because individual solutions had to be created on site at the construction site. This is time-consuming and therefore has a negative impact on installation safety and construction costs. In particular, corners are

Inside or outside corners are problematic and time-consuming to seal.

The present application therefore has the task of providing a solution with which building sealing takes into account the known

Technical rules can be produced safely and more cost-effectively.

[0004] This object is achieved by a molded part, a manufacturing method for such a molded part and a method for building sealing according to one of the attached independent claims.

[0005] According to one aspect of the present disclosure, a molded part for building sealing is intended and suitable for being attached to a building. 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. This can have the advantage that a structural

seal can be achieved quickly and cost-effectively. The molding kart 02957 can be flexible, which makes it easier to grow. The intersection point can also be understood as the cutting area, since in the physical execution it is determined by the material

Molded parts do not produce any sharp edges or corners. He can also

The intersection point can 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 this intersection. In other words, the intersection point can also lie outside the molded part.

[0006] According to one aspect of the present disclosure, a molding has

Building sealing has a conical shell shape. The shape of the cone shell 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.

[0007] According to one aspect of the present disclosure, a molding comprises at least a first sheet molding. The flat molding at least partially comprises a flexible sealing membrane. This can have the advantage that the molded part is easy to produce.

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.

[0013] According to one aspect of the present disclosure, 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 force-fitting and waterproof connection with the subsurface. The at least one lamination can be arranged on the side of a first flat molded part which faces the building when the molded part is installed. 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.

Detailed description of the embodiments

Reference is initially made to FIG. 1, in which a schematic representation of an embodiment of the application is shown. In particular, the embodiment of FIG. 1 shows a molded part 10 which is suitable for inside corners. The molded part 10 comprises a first flat molded part 20 and a second flat molded part 21. The first flat molded part 20 comprises a first surface 11, a second surface 12 and a third surface 13. In the illustrated embodiment, the first, second and third surfaces are 11 , 12 and 13 from the first flat molding 20. In the perspective view of Figure 1, 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.

1 shows the molded part 10 in a mounted state on, for example, a building. In particular, the molded part shown is used to seal a so-called inner corner on a building. The molded part 10 thus extends into the plane of the drawing or sheet; the intersection S is deeper in the plane of the drawing than the edge shown on which the reference number 20 is marked. In the installed state shown, 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.

[0034] In the area of the intersection point S, the second flat molding 21 is applied to the first flat molding 20. In Figure 1, the second flat molded part 21 is shown in dashed lines, since it is applied to the back, i.e. the side facing the building. However, this is optional. It could also be applied to the side of the molded part 10 shown as visible in FIG. 1 and then another surface molded part could be applied, so that on both

Reinforcements are applied to the sides in the area of the intersection point S. In the

1, a liquid sealing compound 30 is also applied in the area of the intersection S. This can cover the second surface molding 21. The liquid sealant 30 can also be applied if no flat molded parts are present.

The molded part 10 has a joining seam 40 between the first 11 and the second

Area 12. In the exemplary embodiment shown, 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 is largely formed by a

Wrapping and joining of the first surface molding 20 achieves its three-dimensional extent. 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 formed 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 Figure 1. Figure 1 shows the molded part 10 attached to a building or in its installed state.

Figure 2 shows 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 in Figure 2 compared to Figure 1. The

Intersection S cannot be seen in the illustration in FIG. 2, but protrudes like that

Figure 2 into the sheet plane. The joining seam 40 can also be seen. At every

Joining seam, the material of the sections to be joined can be designed to overlap, so that a stable joint results.

[0038] Figure 3 shows a further embodiment of the application, a molded part 40192957 which is intended for sealing external corners in an attachment or

Installation condition on a building. As in the representation of Figure 1, three levels E1, E2 and E3 each comprise the first 11, second 12 and third 13 areas. These in turn intersect at an intersection point S. In contrast to the embodiment of FIGS. 1 and 2, the embodiment of FIG. 3 is not conical or cone-shaped.

[0039] The embodiment shown in Figure 3 has two joining seams 40. However, 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 there is an installation or

The mounting state of the molded part 10 results in the three levels E1 to E3, which are in

Intersection S. Alternatively or additionally, at least one joining seam 40 can be arranged on the second surface molding 21 and connect to the first surface molding 20.

4 shows a schematic cross section through a flexible sealing membrane 50. The flexible sealing membrane 50 comprises a TPE layer, which is in one or

Mounting state of the flexible sealing membrane 50 represents the visible side. In an EPDM

An insert 60 is inserted in layer 90. In the embodiment of Figure 4, the insert comprises a known glass fabric, therefore only the

Fibers can be seen that run perpendicular to the plane of the leaf. With a flexible sealing membrane 50, 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 have a surface weight of e.g. 50g/m? and the insert 60 of the molded part 10 or the flexible sealing membrane 50 can have a basis weight of, for example, 16g/m? have. 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? lay.

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.

5 shows a flowchart for a method for sealing a 102957

Building using one of the above-mentioned molded parts 10. In one

In step S10, at least one sealing membrane is applied in a known manner to the respective surfaces of a structure to be sealed.

[0043] In a step S20, a molded part with the intersection point S with a

Corner area of the structure to be sealed. For a molded part 10 for

Inner corners as can be seen in Figures 1 and 2, the molded part 10 cannot be inserted into the corner fully unfolded, for example as shown in Figure 2.

[0044] In a step S30, a lamination 70 on the molded part 10 is preheated. 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 made of S10 by applying heat and pressing. But of course adhesives or liquid sealants can also be used (additionally or exclusively).

[0045] A manufacturing method for a molded part 10 is disclosed in FIG. In a step S10, a first surface molding 20 is produced. This is typically cut out of a flexible roofing membrane, the material of which is suitable for sealing the surfaces (e.g. S10 in Fig. 5).

[0046] In step S20, a second surface molding 21 is produced. The second

Surface molding 21 can, for example, be made 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.

[0047] In a step S30, the first surface molding 20 is shaped. There 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 in a three-dimensional

be brought into shape.

[0048] In a step S40, the shaped first flat molding 20 is made 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 a coverage or width of 20 to 80 mm.

[0049] In a step S50, the second flat molding 21 is applied to the shaped and joined first flat molding 20. This can be the case, for example, in the area of

Intersection point S takes place and / or along the one (or more) joining seam 40.

The second surface molding 21 can be used both in the installed state

The side facing the building or the side of the molded part 10 pointing away from the building can be applied. Several second flat moldings can also be produced and applied, for example from both sides mentioned above.

[0050] In a step S60, liquid sealing compound 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. The description of steps S10 to S60 given above can be applicable, for example, for manual production of a molded part 10.
