Definitions

  • the present invention relates a stockable insulating foam panel and to a wall foam assembly comprising pairs of such opposed stackable insutating foam panels for receiving flowable materials such as concrete.
  • a number of different systems and methods currently exist for making insulating forms for casting a concrete wall comprise pairs of opposed foam panels generally made of rigid foam like polystyrene, which define concrete-receiving cavities therebetween. Those pairs of foam panels are placed one above the other so to form the wall form. Once the concrete is solidified, the form walls remain in place to insulate the wall. Those form walls are typically maintained in spaced and parallel relationship before the pouring of concrete by means of connectors comprising a pair of parallel lateral attachment flanges each embedded in one of the two opposed foam panels, and a connecting web interconnecting the flanges.
  • the piling up of such panels is performed on the site of construction.
  • One object in this field is to obtain foam panels that would allow, on one hand, an easy and very rapid piling up without loosing time and, on the other hand, would allow construction of a stable and solid stacking that will not likely disassemble prior to the pouring of concrete. As can be easily understood, as soon as the concrete is poured, the chances that the stack collapses or disassembles is greatly reduced.
  • EP-A-0275938 Another similar example of an insulating construction panel is shown in EP-A-0275938 , which discloses the features of the preamble of claim 1 and of claim 5.
  • An object of the present invention is to propose a stackable insulating foam panel that will satisfy the above-mentioned need, and more particularly to propose an improved stackable foam panel that allows the construction of a stable and solid stack.
  • a stackable insulating foam panel having a top side and a bottom side each including a median row of alternating projections and recesses having a similar complementary shape, characterised in that the median row of the top side is disposed between two coplanar edge surfaces, above which the projections are projecting and below which the recesses are recessed, and the median row of the bottom side is disposed between co-planar edge surfaces below which the projections are projecting and above which recesses are recessed, each projection and each recess of the top side being opposed respectively to a recess and a projection of the bottom side, whereby the top side and the bottom side of the panel can be interconnected with respectively the bottom side and the top side of like panels.
  • the present invention also concerns a wall form assembly comprising opposed foam panels, as described above, disposed in parallel relationship to make a wall form for receiving a flowable material such as concrete and a plurality of connectors for tying the opposed foam panels together.
  • the form wall assembly of the invention presents the features of claim 5. It comprises:
  • the two coplanar edge surfaces of the foam panel act as shoulders or abutments for the edge surfaces of an interconnected like panel, and thus help to solidify or stabilise a stack built with foam panels according to the present invention.
  • a form wall assembly (10) is suitable to make a form for receiving flowable materiel such as concrete or the like.
  • the form obtained is of the type comprising a plurality of stacked insulating horizontal rows of coplanar substantially rectangular foamed plastic panels (14) abutting one another along horizontal and vertical sides thereof.
  • the form wall assembly (10) comprises a first foam panel (14a) opposed to a second foam panel (14b) in spaced and parallel relationship, and tied together by means of a plurality of connectors (16), as best seen in figure 4 .
  • the foam panels (14) are movable between an extended position, as shown in figure 1 , where the foam panels (14) are spaced-apart to make the form and a collapsed position, not illustrated, where the foam panels (14) are brought close to each other, mainly for shipping purposes.
  • the foam panels (14) each have a top side (15) opposite a bottom side (17) and, as illustrated in figures 1 and 2 , each of the top side (15) and the bottom side (17) is provided with a median row (13) of alternating projections (18) and recesses (19) having a similar complementary shape.
  • This median row (13) is disposed between two coplanar edge surfaces (50) bordering the edges of the panel (14). It has to be noted that the coplanar edge surfaces (50) are preferably provided with a width sufficiently large so as to offer an increased stability between interlocked panels (14).
  • each projection (18) and recess (19) of the top side (15) of one panel (14a) is opposed respectively to a recess (19) and a projection (18) of the bottom side (17) of the same panel (14a), and is facing respectively a recess (19) and a projection (18) of the top side (15) of the other panel (14b), when the pair of panels (14a and 14b) are in the extended position as in figure 1 or 2 , whereby the pair of panels (14a, 14b) can be interconnected with a like pair of panels.
  • the projections (18) and the recesses (19) are generally rectangular. However, projections and recesses of other shapes such as circular, oblong, square etc. could also be used
  • the present invention prefers using projections (18) with rounded-corners. Nevertheless, projections (18) with square-corners or other forms, would still be efficient.
  • each of the projections (18) and the recesses (19) has two opposite substantially convex lateral sides (52, 54) which help the insertion of the projections (18) in the recesses (19).
  • each connector (16) comprises a pair of anchor members (20a, 20b), a first one (20a) embedded in the first foam panel (14a) and the second one (20b) embedded in the second foam panel (14b).
  • Each anchor member (20) has an elongated flange plate (22) extending longitudinally and deep inside the foam panel (14) and an elongated link element (24) connected longitudinally to the flange plate (22) and having a projecting end (26) coming out of the foam panel (14).
  • the projecting end (26) of each anchor member (20) comprises a stabilising plate (28) as best shown in figure 5 parallel to the flange plate (22) and extending flush with the inner surface (30) of the foam panel (14).
  • the link element (24) preferably comprises a plurality of holes (25) therealong.
  • the link element (24) may also be plane solid.
  • the anchor member (20) is embedded in the foam panel (14)
  • the plastic foam material forming the panel (14) is injected to surround the anchor member (20), thereby strengthening the joint between the panel (14) and the anchor member (20) which thus act as an anchor forming part of the foam panel (14).
  • the plastic foam material which is preferably polystyrene or any other material known to a person skilled in the field of plastic foam, is injected to surround the anchor member (20).
  • the connector (16) further comprises a web member (32) extending between the foam panels (14).
  • the web member (32) that is preferably made of a relatively flexible plastic comprises a central portion (44) having a shape adapted to receive and hold metal rods used to reinforce the concrete.
  • the web member (32) further has a first longitudinal side end (34a) hingedly connected to the projecting end (26) of the first anchor member (20a) and a second longitudinal side end (34b) opposed to the first longitudinal side end (34a).
  • the second longitudinal side end (34b) is hingedly connected to the projecting end (26) of the second anchor member (20b).
  • the foam panels (14) are movable between an extended position, as shown in figure 1 , where the foam panels (14) are spaced-apart to make the form and a collapsed position, not illustrated, where the foam panels (14) are brought close to each other, mainly for shipping purposes.
  • each connecting element (64) preferably disposed on the stabilising plate (28) of the projecting end (26) of each anchor member (20) in order to hingedly connect the web member (32) to the anchor members (20) is illustrated.
  • Each of these connecting elements (64) is shaped to form two aligned ridges (66) projecting from the stabilising plate (28), and the space between them defined a longitudinal sleeve (68).
  • a joining pin (70) can be mounted in the sleeve (68).
  • pin receiving holes (71) are provided in the ridges (66) for this purpose, each hole (71) facing inwardly of the sleeve (68).
  • each longitudinal side end (34a, 34b) of the web member (32) defines a corresponding number of arms (72).
  • Each arm (72) has an extremity (74) connectable to a corresponding joining pin (70) so as to be rotatable around an axis defined by the joining pin (70). It can be easily seen that this purpose may be achieved by either mounting the extremity (74) of the arm (72) rotatably around the joining pin (70), or mounting the joining pin (70) itself rotatably in the pin receiving holes (71).
  • the extremity (74) of each arm (72) is provided with a bore (76) for receiving one of the pins (70).
  • the connecting elements (64) may be formed directly by molding during manufacturing of the anchor member (20).
  • a protrusion (78) is generated by the molding process on each side of the ridges (66).
  • these protrusions which are embedded in the concrete with the ridges, have the additional advantage of serving as anchor means for the flanges of the connector in which screws could be inserted to fix, for example, a plasterboard wall thereto.
  • the wall form assemblies according to the illustrated preferred embodiment of the present invention can be easily stacked over each other and linked together.
  • the empty cavity existing between the form wall made of isolating and rigid panels (14) is filled with concrete or with cement based grout. After hardening of the filling material, a composite wall is obtained with the isolating panels firmly attached through the connectors to the concrete inside-wall.
