Abstract

A method for producing a roofing detail part for sealing a roof element, the method including the steps of: (a) providing and/or obtaining a digital model of a roof element to be sealed; and (b) based on the digital model, producing a roofing detail part fitting on the outer shape of the roof element by additive manufacturing.

First claim

The invention claimed is:

1. A method for producing a roofing detail part for sealing a roof element, the method comprising the steps of:
(a) providing and obtaining a digital model of a roof element to be sealed, the digital model being obtained by 3D scanning of the roof element and having an outer shape defined by an outer surface;
(b) based on the digital model, producing a roofing detail part fitting on the outer shape of the roof element by additive manufacturing, the roofing detail part having inner shape defined by an inner surface,
wherein the roofing detail part is produced such that the inner shape corresponds to the outer shape of the digital model,
the roof element is selected from the group consisting of a roof curb, a roof drain, a roof edge, a roof expansion joint, a roof parapet wall, a roof penetration, a roof sleeper, a roof transition, a roof corner, a roof tie-in, and a roof wall, and
the roofing detail part is a cover, a hood, a cap, or a revetment for the roof element.

2. The method according to claim 1 , wherein the scanning of the roof element is performed with at least one of a handheld 3D scanner and a portable 3D scanner.

3. The method according to claim 1 , wherein the additive manufacturing includes 3D printing.

4. The method according to claim 1 , wherein the roofing detail part is produced from a plastic material.

5. The method according to claim 4 , wherein the plastic material comprises at least one selected from the group consisting of antioxidants, fillers, pigments, reinforcing materials, and thermoplastic polymers.

6. The method according to claim 1 , wherein the roofing detail part is produced with a single ply structure.

7. The method according to claim 1 , wherein a wall thickness of the roofing detail part produced is from 0.1-10 mm.

8. The method according to claim 1 , wherein the production of the roofing detail part is effected such that an outer surface of the roofing detail part is similar to the outer surface of the roof element.

9. The method according to claim 1 , wherein step b) includes, based on the digital model of the roof element, generating a further digital model of the roofing detail part to be produced.

10. The method for sealing a roof element comprising the following steps:
(i) performing the method according to claim 1 in order to obtain a roofing detail part fitting on the roof element; and
(ii) installing the roofing detail part on the roof element.

11. The method according to claim 3 , wherein the 3D printing includes fused deposition modeling or fused particle fabrication.

12. The method according to claim 4 , wherein the plastics material is a thermoplastic material.

13. The method according to claim 12 , wherein the thermoplastic material is selected from the group consisting of thermoplastic polyolefins, polyvinylchloride, and ketone ethylene ester.

14. The method according to claim 10 , further comprising connecting the installed roofing detail part with a further sealing element on the roof by heat welding.
