Definitions

  • the present invention relates to an insulating modular panel and to a concrete-wall formwork of which the sidewalls are made up of such modular panels. The latter become an integral part of this wall after the concrete has set.
  • the invention is an improvement of that in Applicant's prior U.S. patent n o 4,742,659 of May 10, 1988.
  • each module is formed of two identical sections disposed in mirror position.
  • Each module section is a panel having inner spaced ribs which terminate short of the top and bottom panel edges and inserts are embedded in the ribs, having apertures opening into the free spaced formed by the ends of the ribs and the panel edges.
  • Tie-rods of adjoining modules are further interlocked by vertical coupling rods to prevent separation of the modules during pouring of the concrete.
  • Reinforcement-bar supports are fixed to these coupling rods, being bent at their ends to form troughs into which horizontal reinforcement bars may be lodged.
  • Another object of the invention is to provide a formwork assembly made of a reduced number of parts of different kinds. In fact, only three kinds are required: modules of the same design for making the sidewalls, tie-rods of the same design at each joint interlocking the modules of the two sidewalls, and standard angle-irons of the same size throughout the assembly.
  • one aspect of the invention is in a modular panel made of foam plastic material and having the usual flat inner and outer faces; upper and lower horizontal edges and vertical end edges.
  • This panel is formed with: - longitudinal coplanar slits extending lengthwise of the upper and lower edges parallel to the inner and outer faces; - a first rabbet opening into the inner face and into the lower edge, and - a tongue along one of the vertical end edges and a groove along the other vertical end edge; the tongue and groove being sized to cooperate, respectively, with a groove and a tongue of like adjoining coplanar panels to form tongue-and-groove joints therewith.
  • the invention is a concrete-wall formwork comprising a pair of sidewalls each formed of a plurality of stacked rows of coplanar panels as described above.
  • the ledges and the second rabbets of adjoining panels operatively cooperate to form horizontal lap joints.
  • the tongues and grooves of adjoining panels operatively cooperate to form vertical tongue-and-groove joints, spaced horizontally along the formwork sidewalls.
  • the longitudinal slits of adjoining panels comprise upward slits in coplanar alignment with the downward slits.
  • the formwork comprises a first group of angle-irons having vertical branches fitting into the upward slits and horizontal branches with holes therethrough, these horizontal branches extending toward the panels inner faces.
  • a second group of angle-irons is also provided which have vertical branches fitting into the downward slits and horizontal branches with holes there­through, these horizontal branches extending toward the panels inner faces.
  • the horizontal branches overlap one another with the holes in register and tie-rods are provided which have a central portion located between the sidewalls and bent end portion extending through the registering holes and into the panels upper edges ; elbows between the portions fitting into the first rabbets.
  • each modular panel is formed with a second rabbet opening onto one of the horizontal edges and onto the outer face; the panel further comprising a coplanar ledge projecting from the other of the horizontal edges in alignment with the second rabbet; the ledge and the second rabbet being sized to cooperate respectively with a second rabbet and with a ledge of like adjoining coplanar panels to form insulating lap joints therewith.
  • At least some of the angle-irons extend beyond the tongue-and-groove joints thereby horizontally interlocking adjacent panels.
  • FIGS 1, 2 and 3 show a modular panel 1 according to the invention.
  • This panel 1 is cut as a generally rectangular body from a standard sheet of foam plastic material, preferably polystyrene, and then formed with an upper longitudinal slit 5 extending lengthwise of its upper edge 7. It is also formed with another longitudinal slit 9 along the lower edge 11 and coplanar with the slit 5. Edge 11 is formed at the factory so as to leave out a ledge 31 to which reference is made below. Both slits extend fully between the end edges 13 and 15 of the panel 1 and are parallel to the inner and outer faces 17 and 19 of the panel.
  • the slits 5, 9, can easily be made in factory by a hot wire which makes it possible to use longer panels 1 thus reducing the number of vertical end joints between successive panels.
  • first rabbet 21 which opens both onto the inner face 17 of the panel and onto its lower edge 11.
  • Each panel 1 is further formed, at the factory, with a tongue 25 along the vertical end edge 13 and with a groove 27 along the other end edge 15.
  • the tongue 25 and groove 27 are appropriately dimensioned to cooperate, respectively, with a groove and a tongue of like adjoining coplanar panels to form tongue-and-grove joints useful in resisting lateral pressure from the concrete mix as it is poured into the formwork.
  • the panel 1 is additionally provided with a second rabbet 29 opening onto the upper edge 7 and also onto the outer face 19.
  • the aforesaid ledge 31 projects from the lower edge 11 and is in vertical alignment with this second rabbet 29.
  • the ledge 31 and the rabbet 29 are properly dimensioned so as to cooperate, respectively, with a second rabbet and with a ledge of like adjoining coplanar panels to form insulating lap joints which serve to avoid the formation of thermal bridges between the outside of the concrete wall and the inside of the building.
  • the slits 5, 9, the first and second rabbets 21, 29, and the ledge 31 extend uninterruptedly between the end edges 13, 15.
  • the modular panel 1 can rapidly and easily be factory-made at low cost and does not require molding nor the embedding of inserts. Indeed, it can easily be cut out of a standard sheet of polystyrene foam.
  • each sidewall is made up of a plurality of coplanar, edge-­ abutting panels 1 horizontally laid in rows one above the others with their tongues 25 and grooves 27 forming vertical joints and their longitudinal slits 5 and 9 forming, when the panels are assembled, upward slits in coplanar alignment with downward slits.
  • the panels 1 are held in vertical alignment by the aforesaid tongue-and-groove joints and in vertical as well as in horizontal alignment by angle-irons 35 each having a vertical branch 37 and a horizontal branch 39 at right angle to one another.
  • a first group of such angle-irons have their vertical branches 37 fitting snugly into the upward slits 9 and their horizontal branches 39 are pierced with holes 41 and 43, of which the purpose is determined hereinbelow.
  • the horizontal branches 39 extend toward and preferably up to the panels inner faces 17.
  • a second group of angle-irons are similarly mounted but with their vertical branches 37 fitting into the downward slits 5.
  • Their horizontal branches 39 are likewise pierced with holes 41 and 43 and extend toward and preferably up to the panels inner faces 17. Branches 39 overlap one another, as shown, in a manner such that their holes 41, being properly positioned, are in register.
  • Tie-rods 45 serve to hold the formwork sidewalls in form parallel vertical position during pouring of the concrete mix.
  • Each tie-rod has a central portion 47 and their end portions 49 are bent out at right angle, joining the central portions 47 through elbows 51. As shown, the central portions 47 are located between the two sidewalls and their end portions 49 extend through the registering holes 41 and are forced into the panels, parallel to their faces, while the elbows 51 fit into the first rabbets 21.
  • the latter may advantageously be V-bent along its central portion 47 to define nicks 55 into which are seated horizontal reinforcement bars 57.
  • Vertical reinforcement bars 59 may also be added, if needed, and secured to the bars 57 and the tie-rods 45 in a manner known in the trade.
  • two spaced rows of angle-irons 35 are first secured to a footing 61 (Fig. 7).
  • the panels of the bottom row are then mounted over the angle-irons by their slits 9 and after their ledges 31 have been removed so that they may sit squarely on the footing by their lower edges 11.
  • additional angle-irons are slid by their downward branches 37 into the slits 5.
  • Other angle-­irons are placed over them with the holes 41 in register and then end portions 49 of tie-rods 45 passed through the holes 41 and driven into the panels, parallel to their faces 17 and 19.
  • the second row of panels may now be placed over the bottom one by inserting the upward branches 37 of the tie-­rods into the downward slits 9. Subsequent rows of panels are set in the same manner.
  • Figures 4 and 5 illustrate that still the same angle-irons 45 may be used in corners of the wall to be built. If a 45° bend is to be achieved, a 45° V-notch 67 is simply cut out of the horizontal branch 39 and the vertical branch 37 is bent at 45°. The same procedure is used for other angles, such as 90° bends.
  • each post would consist of a pair of back-to-back slightly spaced angle-irons 35, temporarily held in place in any known manner against the sidewalls during concrete-mix casting.
  • a stronger but releasable attachment is provided by conventional wall-tie anchors 63 of which the bolts extend between the two spaced angle-irons 35 to be fixed by washers and nuts applied against the free edges 7 of the angle-irons 35 while the anchoring bulbs lie within the formwork to become embedded in the concrete.
  • the posts 61 may further be braced by another angle-iron 35 fixed to its at one end by bolts extending through holes 43 (Fig. 6) and to a ground stake 65 at the other end.
  • Scaffold supports 67 may be fixed to the posts after the concrete has set and after the bracing angle-irons 35 have been removed.
  • the panels 1 can also be used in vertical position to erect a formwork 33′.
  • each sidewall of the formwork 33′ is made up of a plurality of coplanar, edge-abutting panels 1 vertically positioned one adjacent the other with their longitudinal slits 5 and 9 forming vertical slits in coplanar alignement with each other.
  • the panels 1 are held in vertical as well as horizontal alignment by pairs of angle-irons 35 or, preferably, by T-shaped irons 35′ which extend vertically and whose opposite branches 37′, 37 ⁇ are inserted in opposite slits 5, 9 of each joint respectively and whose central branch 39 is pierced with holes and act as a support for the end of a tierod 45.
  • further irons 35′ can be applied horizontally onto each group of panels 1 forming a side wall and screwed otherwise fixed to the vertical irons connecting the panels to keep constant the spacing between these vertical irons and thus prevent the sidewall from "opening".
