Standing seam profile field welding device and method
View Patent ↗This invention relates to a novel thermoplastic profile roofing strip and an apparatus for welding the thermoplastic profile roofing strip to a thermoplastic roofing membrane.
1. An apparatus for welding a thermoplastic profile strip to a thermoplastic membrane, the apparatus comprising:
a first nozzle configured to direct hot air above and below a first raised longitudinal lip along a first edge of a horizontal base of a thermoplastic profile strip placed on a thermoplastic membrane;
a second nozzle configured to direct hot air above and below a second raised longitudinal lip along a second, opposing edge of the thermoplastic profile strip;
a tubular splitter configured to simultaneously supply hot air to the first nozzle and the second nozzle; and
a platform,
a plurality of pressure rollers mounted to the platform and configured to press the first and second raised lips down against the membrane during the hot air applied above and below the first and second raised lips,
a guiding device mounted to the platform and configured to engage a portion of the thermoplastic profile strip to ensure the apparatus remains connected to the thermoplastic profile strip during operation of the apparatus,
wherein the guiding device further comprises a locking device to ensure the guiding device remains connected to the thermoplastic profile strip during operation of the apparatus.
2. The apparatus of claim 1 , wherein the guiding device further comprises a guiding roller to control the elevation of the platform.
3. The apparatus of claim 1 , further comprising a hot air supply to supply hot air to the tubular splitter.
4. An apparatus for welding a thermoplastic profile strip to a thermoplastic membrane, the apparatus comprising:
a first nozzle configured to direct hot air above and below a first raised longitudinal lip along a first edge of a horizontal base of a thermoplastic profile strip placed on a thermoplastic membrane;
a second nozzle configured to direct hot air above and below a second raised longitudinal lip along a second, opposing edge of the thermoplastic profile strip;
a tubular splitter configured to simultaneously supply hot air to the first nozzle and the second nozzle; and
a guiding device configured to engage a portion of the thermoplastic profile strip to ensure the apparatus remains connected to the thermoplastic profile strip during operation of the apparatus.
5. The apparatus of claim 4 , further comprising:
a platform,
a plurality of pressure rollers mounted to the platform and configured to press the first and second raised lips down against the membrane during the hot air applied above and below the first and second raised lips; and,
a guiding device mounted to the platform and configured to engage a portion of the thermoplastic profile strip to ensure the apparatus remains connected to the thermoplastic profile strip during operation of the apparatus.
6. The apparatus of claim 4 , wherein the guiding device further comprises a guiding roller to control the elevation of the platform.
7. The apparatus of claim 4 , further comprising a hot air supply to supply hot air to the tubular splitter.
