SEALING MEMBRANE AND METHOD FOR ASSEMBLY OF SEALING MEMBRANE Russian patent published in 2022 - IPC F17C3/02 

FIELD: sealants.

SUBSTANCE: group of inventions relates to an assembly method for creating sealing membrane by assembling plates made of waterproof material. The assembly method includes following stages: first plate (1), second plate (2) and third plate (3) are placed on the support surface. Then, first continuous fusion line (6) is created on the transverse strip of first plate (1), which overlaps third plate (3). Then, second continuous fusion line (7) is created on the longitudinal strip of second plate (2), which overlaps third plate (3). Fourth plate (4) is positioned on the support surface. Third continuous angular fusion line (8) is created along longitudinal side (4a), along angular zone (4c), which has a convex curved section, and along transverse side (4b) of fourth plate (4), so that to connect fourth plate (4) to first, second and third plates (1, 2, 3).

EFFECT: simplification of the implementation and reduction in the amount of material used.
