Definitions

  • the present invention generally relates to the art of making a concrete wall which is insulated both on the inside and on the outside by using a formwork, made of foam plastic material such as expanded poly­styrene, as a mold into which the concrete mix is poured, which mold is permanently secured to the concrete after the latter has set.
  • a formwork made of foam plastic material such as expanded poly­styrene
  • a formwork has already been proposed which is constituted by hollow modules fully made of insulating foam plastic material; the modules being disposed and stacked in the manner of a brick wall and concrete mix being thereafter poured into the assembled hollow modules acting as a mold which remain permanently secured to the concrete wall after the concrete has set.
  • the very advantageous result is the production of a concrete wall which is fully and permanently insulated both on the inside and on the outside.
  • the known formworks are built, as said above, from brick-like hollow modules molded in factory and formed of a pair of foam plastic panel-like sections held in space relationship by tie-wires or rods of which the ends are solidly embedded in the foam plastic, at the factory.
  • the result is that a module is useful for making a concrete wall having only one pre­determined thickness. It is therefore necessary for the manufacturer to keep a large inventory of modules of varying thicknesses to satisfy customers' demand.
  • a formwork module section made of foam plastic material, which is adapted to serve as one wall of a module of a formwork and which comprises a panel, spaced ribs solid with the panel and projecting from the panel inner face between the panel upper and lower edges, and inserts embedded, each in one of the ribs, the inserts being formed with tie-rod receiving-and-locking apertures; these apertures being located at the upper and lower ends of the ribs short of the panel upper and lower edges.
  • the inserts may be tubular members having hollowed ends opening at the ribs upper and lower ends; these hollowed ends defining the aforesaid tie-rod receiving-and-locking apertures.
  • the inserts may be in the form of channel-shaped members having ends projecting beyond the ribs upper and lower ends; these members each having a central web formed with holes located in the projecting ends, these holes acting as the tie-rod receiving-and-­locking apertures.
  • Another aspect of the invention is a formwork module which comprises a pair of formwork sections as defined above, these sections being disposed in mirror position and the formwork module further comprising tie-rods having hooked ends lockingly engaged into the insert apertures.
  • Still another aspect of the invention lies in a formwork for making an insulated concrete wall and comprising a pair of modules as defined above, which modules are stacked one upon the other with adjoining tie-rods disposed one above the other, in pairs, the formwork further having coupling rods with hooked ends, these hooked ends interlocking with the tid-rods of the aforesaid pairs for preventing vertical separation of the formwork modules as concrete is being poured into it.
  • each section 1 made completely of foam plastic material as aforesaid, comprises a panel 3 having an outer flat face 5 and an inner flat face 7; an upper edge 9 and a lower edge 11.
  • Elongated evenly spaced ribs 13 project from the inner flat face 7 between the edges 9 and 11 and their upper and lower ends 15 and 17 preferably slope from the panel edges 9 and 11 toward flattened tips 19 of the ribs 13, as shown in Figs. 3 and 3A.
  • At least part of each ends 15 and 17 of the ribs 13 forms a flat wall located short of the edges 9, 11, of the panel 3. This may be obtained by cutting appropriate notches 21 and 23 (Figs. 3, 5) through the sloping ends 15, 17.
  • One insert, in the form of a tubular member 25, is embedded in each rib 13, its hollowed end opening in the flat walls of the notches.
  • the ribs 13 preferably have vertical curved sides merging with the panel inner face 7 so that concrete mix poured in the mold formed by the two module sections 1 will produce a concrete column made up of a succession of rounded sections joined by narrow necks between the rib flat tips 19.
  • the module sections 1 are provided with con­ventional tongues 27 and grooves 29 for connection to adjoining modules 31, as illustrated in Fig. 4 where three modules 31 are shown interconnected. These tongue and groove joints of course prevent relative lateral dis­placement of adjoining modules 31 of the formwork.
  • the modules 31 are laid in the same manner as bricks in a brick wall. They are rectangular in shape with appropriate overall dimensions being 16 inches in height and 48 inches in length; the thickness being variable as said before.
  • horizontal reinforcing bars 33 may be laid in the mold under formation in a manner described below.
  • Figure 4 shows the two sections 1 of each module 31 to be interconnected by resilient tie-rods 33, the assembly being made at the building site.
  • the con­nection is best illustrated in Fig. 5.
  • the resilient tie-rods 33 have hooked ends lockingly engaged into the hollowed ends of the tubular members 25 both at the top and at the bottom, in the notches 21, 23.
  • Each hooked end is formed of an inner part 35, flatly engaging the bores of the hollowed ends of the tubular members 25, and an inclined terminal part 37 in edge abutting engagement with the bores so as to prevent accidental withdrawal of the rods 33 from the tubular members 25.
  • Resilient coupling rods 35 are used to prevent relative lifting of stacked modules 31 by interlocking engagement of adjoining pairs of tie-rods 33 at the bottom and at the top of the stacked modules.
  • one end of each coupling rod 35 is bent at an acute angle to form a hook 37 adapted to firmly wind around the lower tie-rod 33 while the other end also bends in the same direction but far less sharply and then rises to form a smooth hooking elbow 39.
  • the hook 37 is first wound around the lower tie-rod 33 and the hooked elbow 39 is then snapped over the higher tie-rod 33, as illustrated in Fig. 5.
  • the tie-rods 33 are bent slightly at their centers and toward one another to form nicks 41 adapted to receive the hooks 37 and the elbows 39, respectively.
  • Reinforcement bar supports may advanta­geously be provided, in the form of the support rods 43 fixed at their centers to the centers of the coupling rods 35; the ends of the support rods 43 being bent in the form of triangular troughs 44 for the seating of reinforcement bars 45.
  • the inserts embedded in the ribs 13 are channel-shaped members 47 of which the ends project into the notches 21, 23 o simply from the slopes 15, 17, of Fig. 3.
  • the central web 49 of the members 47 is formed with holes 51, preferably elongated slots, one such hole being in each of the notches 21, 23, or immediately above the slopes 15, 17 of Fig. 3.
  • the tie-rods 53 have hooked ends that define an open recess engaged over the solid portions of the webs 49 that circumscribe the holes 51.
  • the open recess 55 is an open circle.
  • the open recess in the tie-rod 53 ⁇ is U-shaped while in the tie-rod 53 ⁇ , it is a rabbet.
  • the terminal portions are bent over the main portions to provide flexible arms 55, 55 ⁇ creating a bias action to force the rods 53 ⁇ , 53 ⁇ , against the peripheral wall of the holes 51.
  • the coupling rods 35 and support rods 43 are the same as in Fig. 5.
  • the foam plastic used in the molding of the module sections 1 is preferably expanded cellular polystyrene made according to ASTM D1692-59T. It should of course be homogenous throughout its mass and be free from any accumulation of unexpanded polystyrene particles as well as of any foreign particles.
  • Vertical reinforcement bars may of course be driven through the concrete mix after pouring.
