Definitions

  • the subject invention concerns a prefabricated structural unit for use in the construction of buildings, such as houses or similar structures, said structural unit having an essentially rectangular configuration and comprising a load-bearing panel of preferably reinforced concrete and a preferably rigid insulating material in abutting relationship with at least one of the broad faces of the panel and essentially covering said panel face.
  • Structural units of this kind are used above all as load-bearing wall units for exterior walls or partition walls and/or as load-bearing units or as floor panels, the concrete of the panel or board being either conventional concrete or light weight concrete, depending on the intended application.
  • the insulating material is attached to the broad face of the concrete panel during the manufacturing process proper by means of such methods as pounter- casting, glueing or the like.
  • nails or fasteners In order to be able to penetrate through the insulating material and a sufficient distance into the concrete panel to ensure safe anchoring of the wooden nailing battens -.he nails or fasteners must be compara ⁇ tively long and it is important that they are directed at right angles to the concrete panel when nailed into the latter. If directed obliquely, the nail will often fail to penetrate sufficiently far into the concrete panel, resulting in deficient anchoring of the wooden battens and/or the nail heads splitting the wooden battens which thus need to be replaced.
  • the wooden nailing battens have a con ⁇ siderable thickness in themselves, usually about 20-40 mm. , which means that they project by the corresponding length outwards from the face of the insulating material that is turned away from the concrete panel broad side.
  • One disadvantage of this arrangement is the detraction from the aesthetic appearance of the structural unit which therefore cannot be used with only the insulating material attached thereto to form e.g. interior walls in buildings.
  • additional wall covering therefore is required, e.g. in the form of building panels or gypsum wall boards.
  • the main purpose of the subject invention is to suggest a prefabricated structural unit of the kind defined in the preamble, wherein the disadvantages and imperfections of prior-art structural units have been eliminated.
  • the insulating material is securely anchored to the broad face of the concrete panel by means of bars of thin, preferably galvanized sheet metal, said bars formed with flanges positioned in abutment against the face of the insulating material that is turned away from said broad face of the panel, and also with anchoring members extending transversely with respect to the insulating material and being embedded in the concrete of the panel.
  • Fig. 1 illustrates a prefabricated structural unit in accordance with the invention in a perspective view as seen obliquely from the side, the unit being shortened lengthwise and some parts having been cut away in order to show details behind.
  • Figs. 2 and 3 are sectional views along lines II-II and III-III, respectively, in Fig. 1.
  • the prefabricated structural unit in accordance with the invention is intended for the erection of buildings such as houses and similar structures and in this application the unit may, as in the case illustrated, be used as a load-bearing structural wall panel for external walls.
  • the same structural unit or a modified version thereof could also be used as a load-bearing structural wall unit for partition walls and/or as structural members or as floor/roof panels.
  • the structural unit 1 which in the manner illus ⁇ trated has an essentially rectangular shape, comprises a load-bearing panel 2 and an insulating material 4 positioned in abutment against at least one of the broad faces 3 of the panel so as to essentially cover said face 3.
  • the panel, or slab, 2 is made from concrete, either conventional concrete or light weight concrete or the like, and preferably it is reinforced by reinforcement means not shown in the drawings.
  • the concrete panel 2 is formed along its two facing upper and lower lengthwise edges 5 and 6 with flanges 7 and 8 which are cast integrally with the edges 5, 6 and which at least partly cover the con ⁇ fronting edge faces 9 of the insulating material 4.
  • the insulating material 4 may be made from comparatively rigid sheets 10 of preferably cellular plastics and/or mineral wool. However, there is nothing to prevent the insulating material 4 from being made from some other material or even being foamed in situ.
  • the insulating material 4 is securely anchored to one 3 of the broad faces of the load-bearing concrete panel with the aid of bars, generally designated by 11.
  • the bars 11 are made from thin sheet metal having a thickness of say 0.6 - 1.2 mm., preferably galvanized, but which obviously could be made corrosion-proof in some other way.
  • the sheet metal bars 11 are positioned in the manner illustrated alongside the lengthwise edges 5, 6 as well as alongside the trans ⁇ verse edges 12 of the concrete panel 2, and also inter ⁇ mediate the oppositely positioned lengthwise, or as illustrated, transverse sheet metal bars.
  • All sheet metal bars 11 are formed with flanges 14 abutting against the side 13 of the insulating material 4 that is turned away from the broad face 3 of the concrete panel 2, and they are also formed with anchoring members 15 which are embedded in the concrete of the panel 2 and which extend transversely through the insulating material 4.
  • the sheet metal bars 11 are essentially L-shaped alongside the lengthwise and transverse edges 5, 6 and 12, respectively, of the load-bearing concrete panel 2, with one flange or limb of the L-section forming the flange 14 abutting against the face 13 of the insulating material 4 that is turned away from the panel broad face 3. More precisely, the bar flange 14 is in planar position against and flush with said face 13 of the insulating material 4.
  • the other flange or limb 16 of the L-section member is, as illus- trated, essentially flush with the lengthwise and trans ⁇ verse edges 5, 6 and 12, respectively, of the load- bearing concrete panel 2.
  • Those sheet metal bars 11 that in accordance with the embodiment shown extend vertically intermediate the oppo- sitely positioned transverse sheet metal bars 11 are essentially configured as T-section members the limb of which that forms flange 14 likewise abutting in planar position against and being flush with the broad face 3 of the insulating material 4 that is turned way from the load-bearing concrete panel 1.
  • the shank 17 of the T- section member preferably is doubled and extends into the joint 18 between neighbouring panels 10 of the insulating material 4, placed edge to edge.
  • the sheet metal bars 11 having the essentially L-section configuration along ⁇ side the lengthwise and transverse edges 5,6 and 12, respectively, of the concrete panel 2 serve as head and foot battens and end uprights, respectively whereas the sheet metal bars 11 of essentially T-section configuration serve as vertical intermediate uprights.
  • the intermediate uprights could equally well extend horizontally instead of vertically. In either case at least the end and inter ⁇ mediate uprights could be apertured to allow passage- through of electrical tubes or the like and to form attachment means for securement of electrical boxes and the like.
  • the fasteners or anchoring members 15 mentioned previously are made from sheet metal strips 19 and are welded, preferably spot- welded, to the sheet-metal bars 11 in spaced-apart positions and the strips are formed with an end portion 20 which extends at an oblique angle and which is embedded in the concrete of the panel 2.
  • the sheet metal strips 19 are made from the same sheet metal material as the sheet metal bars 11, i.e. they could be just as thin as the bars 11, and typically they have a width of 20 mm and a length of approximately 200 mm and more, depending on the thickness of the insulating material 4.
  • the sheet metal strips 19 on the sheet metal bars 11 forming the head and foot battens of essentially L-section configura ⁇ tion preferably are welded to the flanges 14 whereas the sheet metal strips 19 on the sheet metal bars 11 forming the end uprights and essentially having an L-section configuration preferably are welded to the flanges 16.
  • the sheet metal strips 19 are welded to said bar in staggered positions on either side of the shank 17 in the manner appearing from Figs. 1 and 2.
  • the sheet metal bars 11 are formed with tongues 21 which are punched from the bar material and which have a dimension of approximately 30 x 20 mm and which are bent in over or into the insulating material 4 to be secured relatively to the latter.
  • tongues 21 which are punched from the bar material and which have a dimension of approximately 30 x 20 mm and which are bent in over or into the insulating material 4 to be secured relatively to the latter.
  • the free longitudinal edges 22 of the flanges 14 and 16 of all sheet metal bars 11 are somewhat bent, in accordance with the shown embodiment, at an angle of say 10 - 30° towards the plane of the flange and consequently the face 13 of the insulating material that is turned away from the broad face 3 of the concrete panel 2, into engagement with said face 13, i.e.
  • the concrete panel 2 forms the external side and the load-bearing structure of the structural unit 1.
  • the primary object of the thin sheet metal bars 11 is to maintain the insulating material 4 in position, the latter material then forming the inner side of the structural unit 1.
  • the sheet metal bars 11 illus ⁇ trated have an aesthetic appearance they could advantageously be used together with e.g. mineral wool panels, the latter forming the insulating material, in applications where no other internal wall covering is needed.
  • the advantages with this arrangement is to provide excellent noise absorption and fireproof properties.
