Detailed Description
Referring to the drawings, and initially to Figs. 1 and 2 thereof, there is illustrated a building roof panel element t according to the invention.
The building panel element 1 comprises a composite insulating panel element. In particular the building panel element 1 comprises a profiled external sheet 2, an internal sheet 3, and an insulating body 4 between the external sheet 2 and the internal sheet 3.
The external sheet 2 of the building panel element 1 comprises a main part 5 and an extension portion 6 at a front end 7 of the external sheet 2. The extension portion 6 extends beyond the front end of the internal sheet 3 and beyond the front end of the insulating body 4. There is no extension portion at a rear end 8 of the external sheet 2 (Fig. 2). The rear end 8 of the external sheet 2, the rear end 9 of the internal sheet 3 and the rear end 10 of the insulating body 4 are flush in-line (Fig. 2).
The extension portion 6 comprises a flexible membrane. The extension portion 6 may comprise a polymeric material, such as polyvinyl, for example polyvinyl chloride. The main part 5 of the external sheet 2 of the building panel element 1 comprises a metallic material, such as steel. The metallic material of the main part 5 of the external sheet 2 of the building panel element 1 is laminated with the same polyvinyl chloride material. The extension portion 6 is fixedly attached to the main part 5. In this case the extension portion 6 is welded to the main part 5. The internal sheet 3 of the building panel element 1 comprises a metallic material, such as steel. The insulating body 4 comprises a foam.
During construction of a building roof; the building panel element 1 may be located in a desired final location on a construction site relative to an adjacent second building panel element. The extension portion 6 of the building panel element 1 may be extended across part of the top surface 11 of the main part 5 of the adjacent second building panel element in this desired final location on the construction site. Then by induction heating the extension portion 6 of the building panel element 1 in-situ on the construction site, the extension portion 6 of the external sheet 2 of the building panel element 1 may be heat-sealed or welded to the top surface 11 of the main part 5 of the external sheet 2 of the adjacent second building panel element.
Fig. 1 illustrates the membrane strap endlap 6. After manufacture of the building panel element 1, the membrane strap 6 is loose to be fitted on-site.
Fig. 2 illustrates the fully sealed strap 6 which may be sealed to the the top surface 11 of the main part 5 of the external sheet 2 of the adjacent second building panel element onsite by means of induction heating.
The invention provides a process of induction welding the membrane 6 to the adjacent separate steel top plate 5 attached to the bottom sheet 3 to heat seal the polyvinyl membrane 6 -panel 5 endlap. The steel top plate 5 is coated/laminated with the same polymer material as the membrane 6 to achieve the welding. The invention provides a site applied method to give an enhanced welded seal to the endlap of the steel roof panel 5 to improve the sealed joint and minimise any leaks at the endlap.
In use during construction of a building roof the building panel element 1 is located in the desired final location on a construction site relative to the adjacent second building panel element. The extension portion 6 of the building panel element 1 is extended across part of the top surface 11 of the main part 5 of the adjacent second building panel element in this desired final location on the construction site. Then the extension portion 6 of the building panel element 1 is induction heated in-situ on the construction site. This causes the extension portion 6 of the external sheet 2 of the building panel element 1 to be heat-sealed or welded to the top surface 11 of the main part 5 of the external sheet 2 of the adjacent second building panel element.
In Figs. 3 and 4 there is illustrated another building roof panel element 20 according to the invention, which is similar to the building roof panel element 1 of Figs. 1 and 2, and similar elements in Figs. 3 and 4 are assigned the same reference numerals.
In this case the extension portion 21 comprises a rigid element. The extension portion 21 may comprise a metallic material, such as steel. The extension portion 21 is formed integrally with the main part 5.
The external sheet 2 of the adjacent second building panel element 20a comprises a recess part 22 at the rear end 23 of the external sheet 2. The main part 5 does not extend to the rear end 23 of the external sheet 2 (Fig. 4). The rear end 9 of the internal sheet 3 and the rear end 10 of the insulating body 4 are flush in-line (Fig. 4). The main part 5 is stepped back from the rear end 9 of the internal sheet 3 and the rear end 10 of the insulating body 4 (Fig. 4).
The adjacent second building panel element 20a comprises a first sealing element 25 in the recess part 22 and a second heat activated sealing element 24 located on the top surface of the first sealing element 25. The first sealing element 25 may comprise a polymeric material and/or an acrylic material and/or an epoxy material, such as butyl rubber. The second heat activated sealing element 24 may comprise a heat-activated adhesive.
During construction of a building roof the building panel element 20 may be located in a desired final location on a construction site relative to the adjacent second building panel element 20a. The extension portion 21 of the building panel element 20 may be engaged with the second heat activated sealing element 24 of the adjacent second building panel element 20a in this desired final location on the construction site. Then by induction heating the second sealing element 24 of the adjacent second building panel element 20a in-situ on the construction site, the extension portion 21 of the external sheet 2 of the building panel element 20 may be heat-sealed or welded to the second sealing element 24 of the adjacent second building panel element 20a.
In use during construction of a building roof, the building panel element 20 is located in the desired final location on a construction site relative to the adjacent second building panel element 20a. The extension portion 21 of the building panel element is engaged with the second heat activated sealing element 24 of the adjacent second building panel element 20a in this final desired location on the construction site. Then the second sealing element 24 of the adjacent second building panel element 20a is induction heated in-situ on the construction site. This causes the extension portion 21 of the external sheet 2 of the building panel element 20 to be heat-sealed or welded to the second sealing element 24 of the adjacent second building panel element 20a.
Fig. 3 illustrates the steel endlap 21 and the heat activated adhesive 24.
Figs. 5 to 9 illustrate another building roof panel element 30 according to the invention, which is similar to the building roof panel element 20 of Figs. 3 and 4, and similar elements in Figs. 5 to 9 are assigned the same reference numerals.
In this case the building panel element 30 comprises an electrical conductor wire 31 wound around an inner core 33 in contact with the inner core 33. The electrical conductor wire 31 is embedded within an outer tube 32 in contact with the outer tube 32. The inner core 33 is of a polymeric material, such as polyvinyl. The outer tube 32 is of the same polymeric material, such as polyvinyl. The inner core 33 and the outer tube 32 together form the sealing element.
The electrical conductor wire 31 may be heated by passing and/or inducing an electrical current through the electrical conductor wire 31. The electrical resistance to flow of electrical current through the electrical conductor wire 31 may be used to heat the inner core 33 and the outer tube 32 of the sealing element to fuse the building panel element 30 to an adjacent building panel element 30a.
During construction of a building roof, the inner core 33/electrical conductor wire 31/outer tube 32 assembly is located in the recess part 22 of the building panel element 30. The building panel element 30 may be located in a desired final location on a construction site relative to the adjacent second building panel element 30a. The extension portion 21 of the adjacent building panel element 30a may be engaged with the inner core 33/electrical conductor wire 31/outer tube 32 assembly of the building panel element 30 in this desired final location on the construction site. Then by passing and/or inducing an electrical current through the electrical conductor wire 31 in-situ on the construction site, the extension portion 21 of the external sheet 2 of the adjacent building panel element 30a may be fused to the inner core 33/electrical conductor wire 31/outer tube 32 assembly of the building panel element 30.
Figs. 5 to 9 illustrate the electrofusion/resistance wire welding embodiment. The inner base core 33 and the outer coating 32 of the rod are of the same plastic resin.
The two ends of the rod are stripped away to allow an electrical connection to be made for example using pins. The rod 31 is positioned and attached to one of the plastic parts that are to be joined. The parts 30, 30a are then aligned and clamped. A variable AC or DC power supply is connected, and a current flows through the rod 31 for a pre-determined length of time causing the entire rod 31 to heat up and thermally fuse the parts 30, 30a together. The rod 31 and the inner base core 33 and the outer coating 32 become an integral part of the weld. In this manner material is added to the junction between the building panel element 30 and the adjacent building panel element 30a in the process of fusing the building panel element 30 and the adjacent building panel element 30a together Referring to Figs. 10 to 12 there is illustrated another building roof panel element 40 according to the invention, which is similar to the building roof panel element 1 of Figs. 1 and 2, and similar elements in Figs. 10 to 12 are assigned the same reference numerals.
In this case the external sheet 2 of the building panel element 40 has no extension portion at the front end 7 of the external sheet 2. The front end 7 of the external sheet 2, the front end of the internal sheet 3 and the front end of the insulating body 4 are flush in-line (Fig. 10).
During construction of a building roof, the building panel element 40 may be located engaging with an adjacent second building panel element 40a in a desired final location on a construction site relative to the adjacent second building panel element 40a. The building panel element 40 is heated in-situ on the construction site in the area adjacent to the junction 42 between the building panel element 40 and the adjacent second building panel element 40a. Similarly the adjacent second building panel element 40a is heated in-situ on the construction site in the area adjacent to the junction 42. A sealing element 43 is heated in an extrusion gun 41 in-situ on the construction site. The heated sealing element 43 is extruded out of the extrusion gun 41 to locate the heated sealing element 43 at the junction 42. By locating the heated sealing element 43 at the junction 42, this causes the first building panel element 40 to be welded to the adjacent second building panel element 40a.
The sealing element 43 is of a polymeric material and/or an acrylic material and/or an epoxy material, such as polyvinyl.
Figs. 10 to 12 illustrate the PVC extrusion welding embodiment. The PVC rods 50 are fed into the hand-extruder device 41. The rods 50 are melted down in the heating chamber of the device 41, and then pushed out through a nozzle/welding shoe 44.
The shape of the extruded beads 43 depends on the types of welding shoes 44.
