摘要
The invention relates to a method for producing a multilayer sealing structure (1) from asphalt sheets (2) comprising an electrically conductive inner layer. For this purpose, asphalt sheets are used, each of which is provided at the factory with an electrically conductive coating (3), which ends with clearance from at least one of the longitudinal edges (2.1, 2.3) and at least one of the transverse edges (2.2, 2.4) of the asphalt sheet or is detachably glued to the asphalt sheet (2), wherein at least one transverse edge (3.2) of the coating (3) detachably glued to the asphalt sheet (2) is removed at the installation site of the asphalt sheets (2), such that the respective asphalt sheet (2) comprises non-conductive edge strips (2.5) as an overlapping and joining region for adjacent asphalt sheets that are to be disposed in the same sealing layer. The conductive coatings (3) of the asphalt sheets (2) forming the lower sealing layer are electrically connected by applying the asphalt sheets, which form the upper sealing layer located on top of same, onto the lower sealing layer such that the conductive coatings (3) of the upper asphalt sheets (2) face the lower sealing layer and are disposed longitudinally and/or transversely offset relative to the lower asphalt sheets so far that the conductive coatings (3) of the respective upper asphalt sheets cover the joining seams of the lower asphalt sheets, whereby an electrically conductive layer is created within the sealing structure that is substantially electrically conductive over the entire surface. The invention further relates to asphalt sheets (2) for producing such a sealing structure (1).
