Abstract

Uprights and plates intended to retain insulating panels (28) compressible against subsidence in a hollow wall as well as beams (22) for retaining rigid insulating panels. These elements are made of sheet metal or sheet metal and have branches (24) made by stamping, leaving an opening (40) in the same shape in the sheet metal. These branches are elongated with a pointed free end (26) and barbs projecting from one of their sides. The internal end of each branch is fully retained on the sheet and each branch can be folded into an operating position at right angles to the sheet from an inoperative position parallel to the sheet. A stop protrudes from the branch to the fold line to lean against the sheet and maintain the branch in its operating position. The branch in the inoperative position protrudes on one side of the sheet and is offset relative to the opening in the sheet so that it cannot be folded through this opening. Thus, the installer cannot bend the branch in the wrong direction.

Description

  • The invention relates to hollow wall reinforcement elements comprising insulating panel anchors, in particular to prevent the collapse of these panels over time.
  • STATE OF THE ART
  • In US Patent 4,761,928 granted in August 1988, to the current inventor, there is described a post for a wall frame comprising several pairs of branches with toothed edges obtained by stamping the core of the upright. The branches of each pair can be folded transversely to the core alternately on either side just before the installation of fiberglass panels and then impale these panels on the branches on each side of the amount so prevent collapse of the panels. A first problem of the patented amount consists in the fact that an inexperienced installer can fold all the forks, or at least the two forks of one or more pairs on the same side of the soul of the upright, thereby preventing the alternation of the directions of the successive forks, essential to the good anchoring of the insulating panels on each side of the upright. If the installer tries to correct an error by folding the offending branches half a turn through their openings in the core, the retention zone of the branch to the amount can yield under the effect of a second folding . Another problem of the patented amount relates to the degree of folding to immobilize the branch to its optimum position of anchoring the glass wool.
  • In the aforementioned patent, no means allows the installer to position the branch in its optimum anchoring orientation of the insulation panel.
  • GOALS OF THE INVENTION
  • The main purpose of the invention is therefore to provide a wall frame amount in which each branch can be folded only in one direction, the branches can be folded alternately on either side of the amount.
  • Another object of the invention is to provide simple means for stopping the folding of the branches in an operative limit position perpendicular to the upright, which is the optimum position for the impalement and anchoring of the insulating panels.
  • Another object of the invention relates to plates and beams for wall frames which are provided with branches having the above characteristics.
  • SUMMARY OF THE INVENTION
  • According to the invention, there are provided hollow wall frame elements provided with means for retaining compressible insulating panels against sagging within a wall. These elements include more particularly amounts and plates. There are also elements, namely beams, for holding rigid insulation panels in position in external walls. These elements are made of sheet metal and are provided with branches made by stamping in a flat portion of the sheet and leaving an opening of the same shape. Each branch is of elongate shape with a sharp open end, barbs projecting from at least one of the sides of the branch and the latter having an integral inner end to said sheet portion along a fold line transverse to the branch, the branch being foldable into an operative position generally perpendicular to said sheet portion and to one side thereof from an inoperative position generally parallel to said sheet portion.
  • A first feature of the invention consists in the fact that each branch, in its position inoperative, protrudes slightly from one of the two opposite faces of said sheet portion and to a portion which overhangs the edge of said opening, so that the branch can not be bent through said opening, because this portion then abuts against the edge of it.
  • A second feature consists in the fact that each branch comprises, in the vicinity of its fold line, an abutment projecting from said first face and which engages against said sheet portion in the operating position of the branch.
  • In a frame upright, the branches are arranged in spaced pairs along the upright and the branches of each pair are close to each other, and in their inoperative position, protrude from opposite sides of the upright soul. to be folded only in opposite directions on both sides of the upright, so as to impale the insulating panels at regular intervals along the upright and on each side thereof.
  • The invention also includes plates provided with the aforementioned branches and which can be attached to wall frame amounts which are wood or sheet metal. These plates can be installed on studs already in place, which requires the removal of plasterboard panels on one side of the wall. The invention also provides for branches provided with barbs on each side and which can be used to impale the insulating panel that is presented to him from any side of the wall.
  • The invention also comprises rigid insulating panels retaining beams and provided with branches according to the invention.

    DETAILED DESCRIPTION OF THE ACHIEVEMENTS OF THE INVENTION
  • As illustrated in Figures 1 and 2, the wall M comprises a frame or rigid frame made of sheet metal elements. These elements include spaced studs, indicated at 22, whose bottom end is inserted into and attached to a joister 23, which is secured to the ground S and whose upper end, not shown, is inserted into and attached to a ceiling joist. , not shown. The uprights 22 may be solidified by U-shaped beams 23A, which pass through appropriate square-shaped openings of a series of uprights 22. These uprights are also provided with circular holes for the passage of conduits 23B for electrical wires or for plumbing. Each upright 22 has a U-shaped profile which comprises a core 22a and two flanges 22b and 22c. These edges are used to attach wall panels P, plasterboard on one side or both sides of the wall. Thus, the webs 22a are perpendicular to the wall panels P. Each post 22 is provided with a series of pairs of branches 24 and 26, which in their operative position are folded at right angles to the web 22a and each side of this soul, and serve to impale and retain insulating panels, flexible and compressible, indicated at 28, specifically fiberglass sheets, which are installed in the space between two successive amounts.
  • Each of the branches 24 and 26, according to FIGS. 1 to 10, is obtained by partial cutting of the core 22a of the amount 22 by means of a matrix and a punch. Each branch has the shape of an elongated finger, of generally rectangular shape, with two free longitudinal edges 32, 34, a free outer point 36 and an inner end 38 integrally retained by the core 22a. After cutting or stamping, the branch 24 or 26 is in a position almost parallel to the core 22a. The branch 24, as shown in Figure 6, projects from the inner face of the core 22a, that is to say the face which is exposed between the tabs or flanges 22b and 22c, while the branch 26 protrudes from the outer face of the soul 22a. Each leg 24, 26 can be bent from its inoperative position indicated above to an operative position at right angles to the core 22a, as shown, for example, in FIGS. 2, 7a and 8. branch is pivoted to its operative position along the fold line, indicated in B in Figure 5, which corresponds approximately to the inner ends of the cutout which formed the longitudinal edges 32 and 34.
  • Cutting branches 24 and 26 result in the formation of openings 40, of the same shape, in the core 22a.
  • The longitudinal edge 32 is straight, while the opposite edge 34 has several barbs 42. Each barb defines a straight edge 42a facing away from the tip 36. This tip promotes the impaction of the insulating panel 28.
  • Each branch 24 and 26 is provided with a reinforcing rib, longitudinal and central 44 which protrudes from the branch on the side of the inner face of the core 22a, while each branch 26 is provided with a similar rib 46, which protrudes from the side of the outer face of the core 22a, as clearly shown in Figure 6.
  • The inner ends of the ribs 44 and 46 are in the vicinity of the fold line B, which is located in a flat part of the soul 22a. On the other side of the fold line B, a boss 48 or 49 is formed in the core 22a in alignment with the ends of the ribs 44, 46 respectively and on the same side as these ribs with respect to the plane of the core. 22a. More particularly, the boss 48 protrudes on the same side as the rib 44, while the boss 49, associated with the branch 26, protrudes on the same side as the rib 46. Thus, in practice, the punch and the die used to cutting the branch 24 act opposite to the punch and die used to cut the branch 26. The ribs 44 and 46 act together with the stops 48 and 49 to engage each other in the operative position of the branch, that is to say in the position in which the branch is 90 degrees to the core 22a, as shown in Figure 7a.
  • According to a main feature of the invention, means are provided to prevent the leg 24 or 26 from being pivoted along the fold line B in a direction which passes the branch through the opening 40 made in the soul 22a. According to the embodiment shown in Figure 5, during stamping, the metal in the region 38 and the fold line B is stretched unevenly transversely to the branch, so it, once cut, moves longitudinally and also laterally of an angle indicated in alpha, so that the edge of the branch become vis-à-vis and interfere with the corresponding edges of the opening 40. The provision of the branches 24 and 26 is as in the patent aforementioned American, namely the branches are arranged in spaced pairs along the amount, the branches of each pair are close to each other, the longitudinal axis of each branch is inclined in the same direction relative to the longitudinal axis of the upright 22 and also the fold line B is inclined relative to the longitudinal axis of the branch 24 or 26, the barbs 42 of the branches are arranged on the same side thereof.
  • Therefore, by bending a branch from its inoperative position to its operative limit position, this branch takes a double inclination with respect to the amount. A first inclination, as shown particularly in Figure 8, wherein each branch is inclined to the flange 22b in a plane perpendicular to the plane of the core 22a; and a second inclination, as shown in FIG. 9, according to which each branch, in its transverse direction, is inclined with respect to the longitudinal axis of the upright 22. In practice, when the insulating panels are installed, more particularly the sheets of fiberglass 28 in the hollow walls, proceed as shown in Figures 8 and 9; it is necessary that the branches 24, 26 are oriented towards the installer, that is to say towards the side of the wall where the gypsum board p has not yet been installed, and it is necessary that the edge of the forks 24, 26, provided with the barbs 42, is directed towards the installer, that is to say towards the open side of the wall, and that these barbs are directed upwards, as shown in FIG. it is easy to install the fiberglass panel 28 by pushing the side edge of the panel 28 against the sharp ends of the forks, according to the arrow F of FIG. 8, and with almost simultaneous movement pushing the insulating panel 28 against the wall panel P already installed according to the arrow Fa of Figures 8 and 9. The inclination of the branches to the installer not only facilitates the impalement panels 28, but also allows, once the panel 28 is in place , at the branches 24 and 26 to pierce many of the easily detachable laminations of the panel 2 8, these laminations being parallel to the wall panels P. Thus, a better retention of the glass fiber against sagging is obtained. The restraint is further improved, since the fiberglass under its weight tends to slide backward according to the arrow F in the figure 9, to lean against the right panel P of Figure 9. Of all this, it follows that, if the installer took care to install the uprights 22 with the ends of the branches 24 and 26, in their position inoperative, directed upwards, as shown in Figures 1 and 2, and that he took care first to install the gypsum board p against the flange 22c uprights 22, opposite the barbs 42, he can no longer be wrong to know in which direction to bend the branches 24, 26 of each pair of branches so that these branches are oriented in the right way, as indicated above. Also, it obtains the optimum operating position at right angles to the core 22a by simply rotating the branches until they reach their limit position. At this time, as shown in Figure 7a, the inner end of the reinforcing rib 44 or 46 abuts against the boss 48 or 49.
  • Note that the stops 44, 48 and 46,49, which maintain the branches at right angles to the core 22a and, therefore, in a horizontal position, that these branches can not tilt downward with the time under the weight of fiberglass sheets 28.
  • FIGS. 11 and 13 show a rectangular plate 54, provided with holes 52, for fastening this plate by means of nails or the like to each of the two opposite faces of a wooden post D (FIG. 12) or to each opposite face of the 22a soul of a metal upright 22 when the amount is made of a sheet thicker than normal and does not allow the tool-free folding of the branches in the core of the sheet. The plate 54 is provided with two pairs of branches 24 ', 26'. The branches 24 'and 26' of each pair are at the same level and are diverging towards their pointed ends. It is only their inner longitudinal edges which are provided with barbs 42 ', similar to the barbs 42, and which face each other in their inoperative position. Each branch 26 'is provided with a rib 46 ', whose inner end is in the vicinity of the fold line B while on the other side of the fold line, a boss 38' serving as a stop, is common to the two branches 24 ', 26. In their inoperative position, all the branches 24 ', 26' protrude slightly from the outer face of the plate 54. Likewise, the bosses 38 'and the ribs 46' project from the outside face of the plate 54. to place the plate against the opposite faces of the upright D with the pointed ends of the branches 26 'pointing upwards and that the plates are applied with the branches 26' outside the upright. Then we choose to unfold that of the branches 24 'and 26' of each pair whose barbs 42 'are going to be oriented towards the installer and inclined upwards in the same direction, as has been written in connection with the figures 8 and 9. The branches can only be bent in the outer direction to the plate, since the branches are offset laterally and also longitudinally with respect to the holes 40 'formed in the plate by the stamping of the branches. Here again, the branches are positively maintained in their operative position at right angles to the plate 54.
  • FIGS. 14 to 19 show a plate 54 'which is installed in the same manner as the plate 54, either on the opposite sides of a wooden post D, or on opposite sides of the core of a conventional post in jail. Plate 54 'has holes 52 for attachment. The branches 26 'of each pair are replaced by a single branch 56, each of whose two longitudinal edges is provided with a series of barbs 58a, 58b and which is also provided with a central and longitudinal reinforcing rib, indicated in FIG. 59, whose inner end is in the vicinity of the fold line B '. The sheet of plate 54 'forms a boss 38 "on the other side of the fold line The width of branch 56 decreases in the direction of fold line B', except for the end pointed end of the branch 56. This pointed end is provided with a bulging extension, indicated at 60, which overlaps by an OS value the corresponding edge of the opening 40 ", which resulted from the cutting of the branch 56.
  • The extension 60 thus prevents the branch from being pivoted through the opening 40 ".The lateral edges of the branch and the barbs 58a and 58b are diverging and inclined with respect to the plate 54 'In the inoperative position of the branch 56, the barbs extend through the opening 40 ", as shown in FIG. 15. In its operative position, shown in FIGS. 16 and 17, the branch 56 is held in its horizontal position at right angles to to the plate 54 'by the boss 38 "and the inner end of the rib 59. As for the plate 54, it is not necessary to choose which of the plasterboard panels P must be installed last because there is always a series of barbs that face the installer, as in Figure 8. In addition, the barbs are angled upward towards the installer, as in Figure 8, and also the decrease of the width of the branch makes the barbs inclined to the installer in a plane perpendicular to the plane of the plate 54 'as the barbs of the branches 24, 26 in Figure 8.
  • The branches 56 fold all on the same side to protrude from the outer face of the plate 54 'in their operative position.
  • The same type of branches is found in FIGS. 20 and 21. These branches are indicated at 56 'and are cut in a post 22', similar to the post 22 of FIGS. 1 to 11. In this case, as in the first embodiment, the branches 54 'are arranged in pairs with the branches of the same pair in the vicinity of one another, and the branches of the same pair can rotate only in oposed directions, (Figure 21) and are maintained angled right with respect to the core of the upright by means of the reinforcement ribs of the branches as well as the bosses 38 ", just as in the plate of FIG. 14. The branches 56 'are also provided with extensions 60' to prevent the branches to be pivoted through the corresponding opening made in the soul of the upright.Thus, the installer will necessarily rotate the branches 56 'alternately on each side of the soul of the upright.The amount provided with these branches has the same advantages as those defined in relation to the branches 56 of the plate 54 'of FIG. 14.
  • Figures 22 to 27 show a metal upright 62 provided with groups of two pairs of legs which are spaced along the upright. The branches of the first pair are indicated at 64 and 64a and the branches of the second pair are indicated at 66 and 66a. The branches of each pair are arranged similarly to the branches 26 'of FIG. 11. The branches 64, 64a fold only towards the inside of the upright 62 while the branches 66, 66a fold only towards the outside of the upright 62. More particularly, the branches of the same pair are arranged at the same level along the upright 62. They are diverging towards their sharp free ends 68 and their inner ends can be folded along the respective fold lines B ". the same pair has a series of barbs 70 along the inner side, which face the other branch of the same pair.The branches are shifted laterally when they are cut, so that the edge of the opening 72, which results from the cutting of the branch in the core 62a, makes interference with the corresponding branch.By referring to Figure 22, the branches 66, 64a project into their inoperative position of the outer face of the soul 62a, while the branches 64, 64a project from the inner face of the same soul 62a. In the same way, the reinforcing ribs 74 of the branches 64, 64a are set back from the outer face of the core 62a, while the reinforcement ribs 76 of the branches 66, 66a are in relief. If it is desired to present the fiberglass panels in the direction of the arrows 78 (FIG. 23), the two superposed branches 64, 66 are folded into their operative position, so that the barbs 70 are facing towards each other. the installer and that the branches are also inclined laterally towards the installer, as in Figure 8. If one wants to install the fiberglass panels in the opposite direction, as shown by the arrows 80, one folds then the pair of branches 64a and 66a, as shown in Figure 24.
  • Referring to FIGS. 25, 26 and 27, it can be seen that the reinforcing rib 74 or 76 extends along the central axis of the limb and its inner end 82 is completely broken down to leave a hole 84 at This constitutes an abutment for holding the branch in operative position at 90 degrees with respect to the core 62a, as shown in Fig. 27. In this case, it is not necessary to have a boss on the part of the soul beyond the fold line B ".
  • Figures 28 and 29 show a plate 86, which is similar to that of Figure 11 and serves the same purpose. It is provided at two different levels of pairs of branches 88 which are similar to the branches 26 'of FIG. 11, with the exception of the stop means for keeping them at 90 degrees from the plate in their operative position, these means consisting of by ribs 76a protruding outwardly of the plate and whose inner end, which defines a hole 84, abuts against the plate 86 in the operative position of the branch at right angles to the plate.
  • Figures 30 and 31 show a branch 90 provided with a stop 92 which terminates at the fold line B ", as for the branches 88 of Figure 28, but which is much shorter than the reinforcing rib 76a and that is bumped at both ends The stop 92 is used when the sheet is thick enough not to require reinforcing ribs in the branch 90. Such a stop 92 comes directly against the plate against the plate 62a or 86 in the operative position of the branch, as shown in Figure 31. A such branch 90 can be used not only for the plates but also for the souls of the metal uprights.
  • FIG. 32 shows a plate 94 provided with branches 96, arranged in divergent pairs, as in the plate 54 of FIG. 11. This plate 94 serves the same purpose as the plate 54. Each branch is offset laterally so that they are prevented. to pass through the opening 98 in the plate. Each branch 96 is provided with an abutment 100 identical to the abutment 92 of FIG. 29. The branches 96 bend along the fold line B ".The plate 94 is characterized by the fact that it is provided with two hooks 102 arranged along the center line of the plate 94. These hooks are folded towards the inner face of the plate 94 and are partially cut in an opening 104 formed in the plate during the stamping of the hooks 102. Each hook has a tab 106, whose height is equal to 1.3 times the distance J between the free bottom end 108 of the tab 106 and the lower edge 110 of the opening 104. The upper edge 112 of the opening 104 is equal at the height of the tab 106, that is to say 1.3 times J.
  • A metal upright 114, of conventional construction and illustrated in FIG. 35, is characterized by the fact that its core 116 is provided with pairs of rectangular holes 118 arranged along the center line of the core 116 at a distance one from the other, indicated by Y, which is equal to the distance between the hooks 102 of the plate 94. These holes 118 are of rectangular shape, and as shown in FIG. 36, their width is approximately equal to 2.2 times the thickness T of the plate 94, while the height of the holes 118 is equal to about 1.2 times the total height C of the hook 102.
  • Thus, as shown in FIGS. 38, 39 and 40, two plates 94, provided with their hooks 102, can be mounted back-to-back on each side of the core 116 with the hooks 102 inserted one beside the other in the opening 118 and in the opening 104 of the other plate 94 and clinging in the opening 118, as shown in Figures 39 and 40. The height of these openings is sufficient for one to return the whole hook with its paw in an elevated position and then let down the plate so that the tab of the hook comes abut against the opposite face of the core 116 of the upright 114.
  • FIG. 37 shows a conventional upright 119 of sheet metal and the like 114, but the openings 118 of which are replaced by conventional holes 120, which can be made on site or made at the factory to fix them with metal screws. plates, such as the plates 54 of Figure 11 in opposite positions on each side of the upright core.
  • FIGS. 41 to 46 show a wall reinforcement element, indicated at 122, which constitutes a beam intended to be placed horizontally and of Z profile, namely a folded sheet to form a central core 124 and two flanges 126, 128 at right angles directed in opposite directions. The core 124 and the flange 126 are provided, at uniform distances along the beam, branches 130 and 132 respectively. The branches 130, which are obtained by cutting in the flange 126, are very similar to the branches 24, 26 of Figures 1 to 11. They have barbs 134 only one longitudinal side. The branches 132, which are cut in the core 124, are similar to the branches 132, except that they are provided with barbs 136 on both sides of the branch. The branches 130, 132 are offset laterally and longitudinally during stamping so as to interfere with the periphery of the opening formed by their stamping. Thus, the branches 130, 132 can only be folded on one side of the web or flange. As for the branches 132, made in the core 124, they can only be folded in the operative position in the opposite direction to a boss 138 made in the core 124 by cutting and which forms a ridge 140 facing the rim 126 provided with branches 130. Each branch 130, 132 is provided with a longitudinal central rib 142, 144, whose inner end 146, 148 abuts against a boss 150, 152 in the operative position of the branch, so as to retain this in a plane perpendicular to the core 124 and the flange 126 respectively.
  • Figures 41 and 42 show the use of the beam 122. It serves to retain in place rigid insulation panels, indicated 154, which are used for the facade walls of a building. These rigid panels are generally made of polyurethane foam or compressed glass fibers. Insulating panels 28 made of uncompressed glass fibers, and therefore flexible and compressible panels are also shown in FIG. 41; they are arranged between the uprights 22. The interior side of the façade wall alone is completed by the plasterboard panels P.
  • Figure 41 shows a concrete floor 156 of a building with posts 22 inserted in a joists 23 fixed to the floor and ceiling truss 160. The outer edge of the concrete floor 156 and the outer side of the hollow wall are closed by rigid insulating panels 162, on which are fixed the horizontal beams 122. The vertical distance between the various beams 122 is equivalent to the height of the panels 154, which are standard dimensions. In the position of the beam 122, shown in Figures 41 and Figure 43-b, the flange 126, provided with the branches 130, is directed upwards and applied directly against the panels 162. The panel 154 is placed from the outside of the front wall first by inserting the upper edge of the panel 154 between the flange 128 and the panel 162 and lifting the panel according to the arrow 164 so that it is impaled by the branches 132 with double barbs. The lower edge of the panel is then simply pushed against the branches 130 of the flange 126 along the arrow 166 and the lower flange of the panel becomes hung not only by the barbs 134 but also by the edge 140 of the boss 138.
  • The beams 122 may be installed in the position shown in Figure 43-c. In this position, the beam was rotated 180 degrees clockwise from the position of Figure 43-b. The panels 154 are also installed from the outside of the front wall but by first inserting the lower edge of the panel in the underlying beam according to the arrow 168 so that this lower edge is impaled by the branches to double barbs 132 and then the upper edge of the panel is pushed against the branches 130 in the direction of the arrow 166.
  • The same beams 122 may be fixed in one or the other of the positions of FIGS. 43-a or 43-d for installation of the panels 154 from inside the building, according to the arrows 170. In the position FIG. 43-a begins by impregnating the lower edge of the panel 154 according to the arrow 168, while in the position 43-d, the impediment is first impinged on the upper edge of the panel according to the arrow 164.
