Definitions

  • the present invention relates to structures made of panel units and connecting pieces, as well as to a method of forming structures essentially made of panel units and of panel units and connecting pieces. More particularly, the present invention relates to structures and a method of forming structures made of extrudable and fusionable material. such as plastic. Background of the Invention
  • panel units and connecting pieces produced by extrusion for the purpose of forming wall or roof sections, as well as other like structures, e.g., the structures described in European Patent Specification No. 0 050 462.
  • Such units and pieces are made of plastic and advantageously some are light-transmitting.
  • These structures possess improved features, such as flexibility and low weight and are relatively inexpensive.
  • One of the major disadvantages, however, of these kinds of structures is the need to support same by rigid supporting members made of metal or wood, or of any other rigid material, so as to render the assembled structures with sufficient rigidity to withstand pressures and forces applied thereto, such as winds and the weight of snow.
  • the common manner of improving the rigidity of such panel units is to produce same with larger inertial moment, namely, with a large bending moment.
  • Another manner, per se known, to achieve rigidity of panels and of panel-based structures is to form panels consisting of an upper sheet and a lower sheet, interconnected by a plurality of partitions of large dimensions. The spacing between the sheets, namely, the distance ofthe material from the center of gravity will, inter alia, determine the rigidity of the structure. Since, however, such structures are efficiently produced by extrusion, the more sheets and partitions in a single panel, the greater number of extrusion dies required. Also, in order to achieve a large moment of inertia and hence rigidity, there must be invested greater effort in providing a costly die and the inevitable complications in operating such a device.
  • a structure made from a plurality of thermoplastic fusionable panel units and connecting pieces characterized in that at least said panel units are formed by extrusion and said panel units and/or connecting pieces are provided with at least one electrical conductor extending along a surface area in the direction of extrusion, and that the connection between contacting panel units and/or the panel units and the connecting pieces, is effected by mechanical joining means, as well as by fusion, thereby forming a non-sliding, rigid and thermally insulated structure.
  • the invention further provides a method of forming rigid structures essentially assembled of thermoplastic fusionable panel units and connecting pieces, comprising producing structural panel units of extrudable and fusionable material and providing connecting pieces, applying at least one electrical conductor along a longitudinally extending surface area, or at close proximity to a surface area of said panel units and/or connecting pieces, contacting said surface area with a surface area of another panel unit and connecting the units by said connecting pieces to form a self-sustained structure, applying pressure along at least sections of said contacting surface area, and passing current through said electrical conductor to cause the contacting surface areas along said electrical conductor to fuse, thereby forming a non-sliding, rigid and thermally insulated structure.
  • Fig. 1 is a cross-sectional view of two flanged panel units and a connecting piece according to the present invention
  • Fig. 2 is a cross-sectional view of another embodiment of two flanged panel units and a connector piece
  • Fig. 3 is a perspective view of the connecting piece of Fig. 2, showing the electrical conductors
  • Fig. 4 is a cross-sectional view of a double-glazed structure, according to the invention
  • Fig. 5 is a perspective view of a portion of a bent double- glazed structure formed in accordance with the present invention.
  • FIG. 1 there are shown two solid panel units 2 of the type having joining flanges 4.
  • the panels are made of extrudable and fusionable material such as plastic material.
  • a connector piece 6 adapted to be pushed over the joining flanges 4, so as to join the outside surfaces of the flanges by pressure to establish a self-sustaining structure.
  • each of the panels 2 and/or wing portions 8 of the connecting piece 6 is provided with a conductor 10 in the mid-section of one of the flanges 4, or at the edges of the wing portions 8 of the connector piece 6, or at any other location where the surfaces of the connecting piece 6 are in contact with the flanges 4.
  • the flanges 4 Upon the passing of a suitable current through the conductors 10, the flanges 4 are fused together with the connecting piece 6.
  • the conductors 10 may be affixed to the bases of the flanges 4. instead of to the edges of the wing portions 12 of the connector piece 6, or may be attached onto any other suitable surface of the panel unit 2 or connecting piece 6.
  • the electrical conductors 10 may be embedded just underneath a surface, in close proximity to the surface of a panel or of a connecting piece during production (e.g., extrusion), or may be attached thereto after the production of the panel units and connecting pieces by means of an adhesive, fusion or the like.
  • the heat required to melt the thermoplastic material from which the panel units or connecting pieces are made can be obtained by passing current through the same conductor which is to be attached, during the attachment process.
  • the shape of the electrical conductors can be round, as that of the commonly used resistance wire, rectanglar, a flat strip made as a strip of a metal foil, or of any other shape.
  • the size of such a wire-shaped conductor or the width of such a strip will be determined by various considerations, including the specific material of which the panel unit and connecting piece are made, the current to be passed through the conductor, the duration of time that the current is to be passed, all for the purpose of fusing the unit to a connecting piece or to another panel unit by means of heat, as the case may be.
  • the strength of the bond to be formed between a panel unit and another panel unit or connecting piece will determine the size and shape of the electrical conductor in consideration of the heating capability of the conductor in fusing two contacting surfaces immediately adjacent to the conductor.
  • the spacing between conductors will, of course, also depend on the configuration of panel units and connecting pieces used in assembling a specific structure.
  • connection by fusion between, e.g., one or more panel units and at least one connecting piece for forming a structure is effected in addition to the conventional manner of connection by mechanical means.
  • Fig. 2 there are shown the end portions of two per se known, adjacently disposed flanged panel units 2 fitted with a U-shaped connecting piece 6. Both the external surfaces of the flanges 4 and the internal surfaces of the wing portions 8 are provided with tooth-like detent means 12 for joining the units.
  • the detent means 12 of the flanges 4 or connector piece 6 are provided with electrical conductors 10 as shown, after effecting the mechanical engagement and the pressing together of the units and the connecting piece, the flanges 4 and the connecting piece 6 are fused, so as to furnish the structure with much higher rigidity and improved thermal insulation.
  • the fusion of the connecting pieces with the panels effectively rigidifies the entire connecting assembly, turning the latter into a rigid rib extending along the entire connecting edges of two adjacent panels. This results in a substantial reduction in the use of supporting structures and an improvement in the aesthetical appearance of the thus-formed structure.
  • the panels 2 may also be directly fused to each other for added rigidity.
  • conductors 14 and 16 may be provided for directly interconnecting the flanges 4 or lateral edges of the panels, respectively.
  • the panel units 2 may be light-transmitting panels or even panels of optical quality.
  • a connector piece 6 fitted with electrical conductors 10.
  • the electrical conductors 10 are attached to the selected surfaces ofthe connector by means of adhesive aluminum foil pieces 18.
  • the foil pieces 18 also function as heat diff sers to avoid overheating of the fusible material (e.g., plastic) at the end portions of the connectors or panel units.
  • Fig. 4 a double- glazed wall or roof construction, formed with the use of H-shaped connectors 20 fitted with electrical conductors 10 along the detent means 12 and/or along the outside surfaces of the flanges 4 and of the end surfaces of the abutting panel units 2.
  • FIG. 5 there is shown the interconnecting portion of four contacting bent or bowed panel units, forming a bent or curved structure, e.g., a curved roof.
  • the H-shaped connecting piece 20, shown in greater detail in Fig. 4 interconnects the panels 2, advantageously assembled on site, to form a bent or curved double-glazed wall or roof structure.
  • the structure is easily bent on site due to the relative flexibility of the panel units and elongated connecting piece 20, to assume the exact bending curvature fitting a prepared support and is provisionally held in this form by the built-in detent means 12, and/or by any other externally provided panel-contacting and pressure-applying means.
  • the panels are fused with the connecting piece, forming an integral, rigid, bent roof or wall structure.
  • detent means 12 may seem to be redundant when the actual improved bonding between the panel units and connecting pieces is achieved by fusion; however, such detent means, or other means, may serve as provisional connectors and contact-effecting means prior to the fusion action permanently connecting the units and pieces by fusion.
  • Such connectors interconnect the individual panels in such a manner as to apply contacting pressure between the edges to be fused together, thereby avoiding the need to utilize auxiliary, provisional joining and supporting elements, as well as means for clamping together joining parts, for assuring proper fusion.
