Definitions

• the present invention relates to a method of adhering, splicing and/or applying roof, floor or wall material.
• the rolled-out material When laying roofing material, the rolled-out material is spliced and/or adhered so that when the overlapping rolls are spliced or adhered they are heated to melting or softening point by means of an open flame, such as from a blow-lamp or an LPG burner, or by means of hot air from a burner where open flames also occur. In all cases there is a considerable risk of fire. The same applies when an older roofing felt is to be covered with new roofing felt or some other similar material.
• the method according to the invention offers a solution to these and other associated problems and is characterised in that strips, rolls or sheets of or containing metallic layer material 1 such as aluminium (Al), copper (Cu), iron (Fe), brass or the like are attached to a layer of bitumen, asphalt or other tar-like or polymer products, or are coated or prepared with such material, and that rolls of composite material or roofing material are applied side by side and that strips are applied between, under or over the adjacent edges, i.e. a completely metallic layer of the metallic material, or that coated rolls of composite material with such layers are applied mutually overlapping, said strips or overlapping portions being thereafter heated inductively or resistively and adhesion/splicing being achieved.
• metallic layer material 1 such as aluminium (Al), copper (Cu), iron (Fe), brass or the like
• This method entails considerably less risk of fire and a quick and efficient method of applying roofing material or the equivalent on walls and floors.
• the metallic strips also provide efficient heating if the heat source is correctly set
• the invention can advantageously be utilized for full adhesion, i.e. the full width of the roll is heated, and previously-laid roofing material can be covered with new material according to the invention, or the invention may be used just for adhesion/splicing.
• the inductive or resistive heating can be performed using conventional means that can be rolled or pushed along the joints.
• Figure 1 describing full adhesion, shows strips or rolls composed of a metallic layer 1 (Al, Cu, Fe, brass or the like) and a layer 2 of bitumen, asphalt or tar-like or polymer products, arranged to overlap when the roof, wall or floor is applied.
• the roll length A must be heated first, followed by the roll length B (or vice versa), to softening or melting point so that splicingadhesion can occur.
• the strips or rolls, composed of layers 1 and 2 may also be designed so that the metal layer 1, possibly a foil, is prepared or coated with bitumen, asphalt or the like as above, and heating is performed by the metallic layer 1 being heated when the inductive/resistive heater passes the joint.
• Figure 2 shows an embodiment with an upper splicing strip 4 between two composite layers 5, 6, and an outer lower strip 4.
• Figure 3 shows such a splicing strip 4 placed below (or above) these composite layers.
• Such splicing strips 4 can also be used in conjunction with conventional roofing material (or the equivalent for floors or walls) and the composite layers (1-2) may also be placed in this way on top of either newly-laid or old roofing material.
• the metallic layers 1 may be in the form of foil, unperforated and possibly embossed. Heating is of course performed at the location of the joint
• the intermediate layer 4 between two composite layers 5, 6 may possibly be in the form of foil with a thin coating of bitumen, etc.
• Frequencies of 4-500 kHz are preferably used for the inductive heater, but both lower and higher frequencies are feasible.
• the method according to the invention entails a considerably simplified method of laying roofs, etc. as well as a great improvement over methods used hitherto from the environmental aspect
