Description

  • The present invention relates to a lost or integrated formwork for the manufacture of a wall of concrete or similar material. This formwork consists of two metal formwork walls provided with vertical stiffeners and placed opposite each other. They are connected by a connecting device separating the walls by creating a space between them intended to be filled with a material such as concrete.
  • In order to guarantee the solidity of walls of buildings or other concrete structures, it is planned to have an additional vertical reinforcement inside the walls. A technique often used is to use this formwork system as a formwork lost or integrated that is to say with a form that remains as an integral part of the wall after pouring the concrete inside.
  • The documents EP0883719 (= WO97 / 31165 ) and WO02 / 38878 disclose a lost or integrated formwork comprising an outer wall and an inner wall, these walls, called formwork walls, comprise vertical stiffeners consisting of generally U-shaped profile bars. The formwork walls are connected by connecting devices each consisting of by a bar bent substantially zig-zag and articulated at the stiffeners. These devices maintain a determined space between the formwork walls in which the concrete is poured.
  • The document WO03 / 010397 describes the lost or integrated formwork of the aforementioned documents where reinforcing elements are introduced between the lateral sides of the U-shaped sections of two stiffeners placed opposite each wall. Each reinforcing element comprises at least one vertical bar and at least two horizontal crosspieces adjusted to slide inside the profile of the stiffeners. This reinforcement element is added after the deployment of the formwork walls by sliding in the stiffeners which act as guide rails. The U-shape of these stiffeners ensures the maintenance and stability of this frame member while facilitating its insertion.
  • The various elements of the formwork such as the formwork walls, the connecting devices and the stiffeners are prefabricated at the factory and then assembled using appropriate fasteners to form the formwork. The latter thus produced leaves the factory in folded form thanks to the joints of the connecting elements on the stiffeners, then it is unfolded on the construction site during its installation in order to constitute a wall.
  • The forms of the prior art mentioned above have excellent resistance to high stresses due in particular to high intensity seismic shaking. However, since the zig-zag shape of the connecting elements between the walls does not conform to the straight reinforcement usually used, it is difficult for civil engineers to accurately quantify their contribution to the strength of the wall.
  • The object of the present invention is to increase the rigidity of the lost or integrated formwork during their installation, to facilitate the work of civil engineers who can easily determine the contribution of the horizontal reinforcements while reducing the manufacturing costs of these. this.
  • This object is achieved by a concrete wall formwork having two parallel formwork walls placed opposite each other provided with profiled bars forming vertical stiffeners and connected by at least one articulated connection device making it possible to maintain the formwork walls. either at a spacing defining a space for receiving a filling material such as concrete, or folded for storage and transport, characterized in that the connecting device comprises a first horizontal straight bar parallel to the first formwork wall and through the stiffeners of said first wall, a second horizontal straight bar parallel to the second wall formwork and passing through the stiffeners of said second wall, said second bar being located opposite the first bar, and a plurality of connecting bars perpendicularly connecting the two horizontal bars, said connecting bars as articulated around said horizontal bars.
  • The notions of vertical and horizontal are relative because the entire formwork can be rotated at an angle of 90 °. Thus the vertical elements at the beginning become horizontal and vice versa. In practice, during the construction of a wall the formwork is placed on a substantially horizontal surface (floor or floor slab) so that the stiffeners are arranged in the vertical direction.
  • According to a preferred embodiment, the stiffeners consist of U-shaped profiled bars whose opening is directed towards the inside of the formwork. These stiffeners, fixed on the formwork walls at substantially regular intervals, are pierced with lateral holes of sufficient diameter to ensure the free passage of a horizontal straight bar. The connecting bars are preferably arranged between the lateral sides of the U that form the stiffeners in order to limit their movement along the horizontal bars and to maintain a constant interval between them corresponding to that between the stiffeners.
  • The horizontal bars are also distributed at substantially regular intervals over the height of the formwork walls. This configuration makes it possible to have binding bars at regular intervals both in the direction of the height and in the direction of the length of the formwork. This arrangement ensures a uniform spacing between the formwork walls during the pouring of the concrete. The joints of the connecting bars around the horizontal bars allow the folding of the formwork walls on one another during storage and transport from the factory to the site.
  • The main advantage of the connecting device according to the invention compared to the zig-zag device of the prior art lies in that it allows the use of bars of larger section. Indeed, as the horizontal bars parallel to the formwork walls are rectilinear, it becomes possible to increase their diameter without major disadvantages at the manufacturing level unlike the connecting device formed of a zig-zag bar. In this case, the larger the section of a bar becomes, the more the means used for folding and setting up the bar become consistent and reach a high cost. Thus, by eliminating the folding operations of the bars of the connecting device, it contributes to the reduction of manufacturing costs.
  • The establishment of the bars of the connecting device according to the invention is also easier because they are arranged by sliding through holes previously drilled in the stiffeners to a suitable diameter. The section of the connecting bars can also be increased in proportion to that of the horizontal bars.
  • Thus, thanks to the possibilities of using large section bars, the connecting device becomes more rigid, which makes it easier to place the formwork on the site, better alignment and consequently the possibility of reducing the thickness of the coating layer. The latter consists of a mortar coating applied to the outer faces of the formwork walls after pouring the concrete into the formwork. Because of the greater rigidity, a better flatness of the formwork walls can be obtained to distribute on them a coating of a uniform thickness over their entire surface without having to compensate for deformations.
  • Another advantage of the structure of the formwork according to the invention is that it allows a facilitated introduction of a floating armature between the two formwork walls in the intervals between the connecting bars. This frame composed of at least two vertical bars connected by transverse bars slips into the intervals from the top of the form when it is placed at the location of the wall to be built before pouring the concrete. Alternatively, the frame can be hung on the upper part of the form to maintain its position when filling the formwork with concrete.
  • In addition, filling tests have shown that the formwork according to the invention makes it possible to reduce the risks of segregation of the concrete. The presence of barriers to the flow of concrete that act as a filter slows the fall of the concrete and reduces the risks of segregation.
  • The obstacles to the flow of concrete between the two formwork walls are of the same order in the structure according to the invention as in that where a zig-zag connection device is used. In both cases, the elements of the connecting device that pass through the space between the walls form many obstacles to the flow of concrete.
  • The invention will be better understood from the detailed description which follows and which refers to the appended drawings which are given by way of non-limiting example, namely:

    • Figure 9b shows the variant of Figure 9a seen in a section between the formwork walls.
    • Figure 10 shows a top view of a third connection variant between two shuttering panels using U-folded flexible bars and a vertical reinforcing bar.
  • Figure 1 shows a portion of a concrete wall formwork having two parallel form walls (1, 1 ') placed opposite each other. Each wall (1, 1 ') is provided with U-shaped vertical bars whose opening is directed towards the inside of the formwork. They are spaced preferably at regular intervals along the entire length of the walls. These bars called stiffeners (2, 2 ') contribute to the stability of the formwork walls (1, 1') which are generally made of relatively flexible wire mesh panels. The stiffeners (2, 2 ') are fixed to the mesh of the formwork walls (1, 1') by welding, by hooking on lugs or by ligation by means of metal wires.
  • The formwork walls (1, 1 ') comprise horizontal ribs distributed at intervals more or less regular over the height. These ribs serve to stiffen the walls (1, 1 ') to prevent their deformation under the pressure of the concrete, especially in cases where the intervals between the stiffeners (2, 2') vertical are long.
  • The meshes of the mesh of the formwork walls (1, 1 ') have a size adapted to the passage of the finest particles of the filling concrete. This fine concrete leaving the formwork is used for the final coating of the wall because it facilitates the application of a mortar coating (outside) or plaster (inside the building).
  • The formwork walls (1, 1 ') are kept parallel at a determined distance by means of connecting devices distributed over the entire height of the walls. These devices each consist of a pair of parallel straight horizontal bars (3, 3 ') placed opposite one another and connected by a plurality of perpendicular connecting bars (4) whose lengths are substantially equal to the distance separating the formwork walls (1, 1 '). The horizontal bars (3, 3 ') are integral with the formwork walls (1, 1') to which they are held by means of the stiffeners (2, 2 '). The latter are pierced with holes in the lateral sides of the U-shaped section with a diameter greater than that of the horizontal bar (3, 3 '). These holes are positioned facing each other on each lateral side and opposite those of the lateral sides of the neighboring stiffeners so as to allow a free sliding of the horizontal bar (3, 3 ') as it passes through each stiffener (2, 2 ') of the shuttering wall (1, 1'). The connecting bars (4) are pierced with a hole at each end allowing the free passage of the horizontal bar (3, 3 '). This fixing of the connecting bars (4) allows their articulation around the bars horizontal (3, 3 ') through which the formwork walls (1, 1') can be folded against each other during storage or transport. These connecting bars (4) are preferably arranged between the lateral sides of the U formed by the stiffeners (2, 2 ') in order to prevent their movement along the horizontal bars (3, 3') or during the setting of the formwork during the pouring of concrete.
  • According to a first variant represented by FIG. 2 which is a view from above of the formwork of FIG. 1, the stiffeners (2, 2 ') of the facing walls (1, 1') are located opposite the one of the other. The connecting bars (4) are placed between the lateral sides of the U of two stiffeners (2, 2 ') opposite and articulated around the horizontal bar portion (3, 3') located between these sides.
  • According to a second variant shown in Figure 3, the stiffeners (2, 2 ') of a formwork wall (1, 1') are offset from those of the wall opposite. In this configuration, only one of the ends of a connecting bar (4) is articulated between the lateral sides of the U of a stiffener (2, 2 ') while the other end is articulated around a portion of the horizontal bar (3, 3 ') opposite between two stiffeners (2, 2'). This variant reduces the width L1 of the form when folded. Indeed, once the formwork folded, two opposite stiffeners (2, 2 ') are placed next to each other on the horizontal bars (3, 3') (Figure 3a) instead of superimposed on the one on the other as in the first variant, see Figure 2a. The difference in width (L1-L2) of the folded form is equivalent to the distance D separating a horizontal bar (3, 3 ') from the edge of the lateral sides of a stiffener (2, 2') as illustrated in FIG. 3a. This distance D depends on the dimensions of the stiffeners (2, 2 '), the section of the horizontal bars (3, 3') as well as the position of the through hole of these bars in the lateral sides of the stiffeners (2, 2 '). ). This gain in width can have an advantage when storing or transporting a large number of stacked forms by reducing their size.
  • FIG. 4 shows several possibilities (a, b, c, d) of metal frames (5) which are placed from the top inside the formwork in the spaces delimited by the connecting bars (4) and the formwork walls. (1, 1 '). These reinforcements (5) are installed on the site when the expanded formwork is positioned at the location of the wall to be created before the pouring operation of the concrete between the formwork walls (1, 1 '). They are intended to be completely embedded in the concrete and serve to reinforce the wall.
  • The continuous spaces from top to bottom of the formwork allowing easy introduction of different types of reinforcement (5) of height substantially equal to that of the formwork. The examples illustrated in FIG. 4 are not exhaustive, other reinforcing structures (5) comprising a variable number of vertical (7) and / or horizontal bars (6) arranged in various ways are also possible provided that their dimensions are adapted to the spaces between the formwork walls (1, 1 ').
  • The variant (a) of the armature (5) of FIG. 4 comprises two vertical bars (7) connected by a plurality of horizontal bars (6). This floating type frame (5) is arranged in a central zone of the space between the formwork walls (1, 1 '). It is held temporarily by an attachment device during the pouring of the concrete to prevent it from moving. The variant (b) comprising four vertical bars (7) connected by horizontal bars (6) provides better stability.
  • Variants (c) and (d) are distinguished from the previous by the presence of a fixing device in the form of hooks (8) to hold them in place during the pouring of concrete without the use of a temporary fastening device. The attachment is made on the upper and accessible part of the formwork either on the connecting bars (4) (variant c), or on the horizontal bars (3, 3 ') (variant d) of the last connecting device. The hooks (8) can be replaced by a tie or a wire tie.
  • FIG. 5 illustrates a cross-section along the axis AA of the formwork of FIG. 4 which shows the variant (d) of the reinforcement (5) hooked on the highest horizontal bars (3, 3 ') and which is prolonged on the entire height of the formwork.
  • FIG. 6 shows another variant of the formwork comprising an insulating panel (9), for example made of expanded polystyrene, between one of the formwork walls (1, 1 ') and the corresponding stiffeners (2, 2'). The use of this type of formwork no longer requires the addition of additional insulating panels when the wall is completed, which also contributes to the reduction of construction costs.
  • This insulating panel (9), extending over the entire surface of the formwork wall (1, 1 '), is fixed to the back of the stiffeners (2, 2') by means of screws or fasteners (10) which, through the panel (9), maintain the form wall (1, 1 ') against the stiffeners (2, 2'). The form wall (1, 1 ') thus located on the outer face of the insulating panel (9) is coated with fine concrete after the filling of the space between the insulating panel (9) and the second wall formwork (1, 1 '). Reinforcements (5) can be inserted into the space between the connecting bars (4) in the same way as in the formwork configuration without insulation board as shown in Figures 4 and 5.
  • FIG. 7a shows an exemplary embodiment of a connecting bar (4) constituted by a steel bar, for example, whose ends (12, 12 ') are curved so as to be wrapped around the horizontal bars (3, 3 '). This embodiment, being an alternative to the bars (4) pierced with a hole at each end serving as a passage for the horizontal bars and constituting the hinge around them, can of course be applied to the examples of formwork described above and illustrated in FIGS. 1 to 6. In order to avoid the displacement of the connecting bar (4) along the horizontal bars, at least one of its ends (12, 12 ') is wound around the horizontal bar portion ( 3, 3 ') lying between the lateral sides of the U formed by the stiffeners (2, 2') of one or the other of the formwork walls (1, 1 '). In the field of formwork reinforcement, bending or curvature of steel bars is preferable to drilling. Indeed, a bar at the ends formed as in Figures 7a and 7b will have a higher resistance and directly proportional to its section a similar bar pierced with through holes.
  • The preferred configuration shown in FIG. 7b is distinguished by the fact that the stiffeners (2, 2 ') of a formwork wall (1, 1') are staggered relative to those of the facing wall in a manner that allowing the connecting bars (4) to be arranged perpendicular to the horizontal bars (3, 3 ') with each of their ends (12, 12') in the profile of the corresponding stiffeners (2, 2 '). The advantage of this arrangement is to be able to reduce the width of the formwork, once folded, similar to the variant illustrated in Figures 3 and 3a, while ensuring good stability of the form when it is deployed on site.
  • A concrete wall is usually constructed with a formwork consisting of several formwork panels interconnected. Figures 8a (seen from the top of the form) and 8b (section between the formwork walls along the axis A-A) show a first connection variant between two formwork panels a and b. The continuity of the horizontal bars (3, 3 ') between two contiguous panels (a, b) is ensured by the installation on the site, at the junction of the panels (a, b), of a set consisting of a vertical bar (14) on which are welded inverted U-bars (13) at the same spacing as the horizontal bars (3, 3 ') of the panels (a, b). This assembly (13, 14) is introduced from the top at the junction of the panels (a, b) and then rotated on itself at 90 ° so that the U-shaped bars (13) rest on the last connecting bars ( 4) at the junction of each panel (a, b) while keeping them solid to each other.
  • Figures 9a (seen from the top of the form) and 9b (section between the formwork walls along the axis B-B) show a second connection variant between adjacent panels (a, b). It consists in using flexible steel bars (15) in the form of a loop penetrating between the formwork walls at the level of the horizontal bars (3, 3 ') and placed on the last connection bars (4) towards the junction of the panels ( a, b). In order to keep in place these looped bars (15), a vertical reinforcing bar (16, 16 ') is introduced from above into the space between a connection bar (4) close to the junction and the curvature ( 15 ') of the loop formed by the bar (15) on each of the two panels (a, b). These reinforcing bars (16, 16 ') thus pass into the rounded portion (15') of the loop (15) at each connecting bar (4) located one above the other in the adjacent the junction of the two panels (a, b) formwork as shown in Figure 9b.
  • The loop bars (15) are preferably field mounted after deployment of a first form panel (a) by inserting them between the form walls (1, 1 ') on one of the vertical sides at the connecting bars (4) so as to overtake the panel (a). A second panel (b) is then deployed and placed in line with the first by introducing the portions of the looped bars (15) protruding from the first panel (a) between the formwork walls (1, 1 ') of the second panel at the connecting bars (4).
  • The vertical reinforcing bars (16, 16 ') are placed from the top of the panels (a, b) to complete the linking operation of the two panels (a, b).
  • Figure 10 shows a third connection variant between two shuttering panels a and b where they are connected by U-shaped flexible steel bars (17). The bent portion (17 ') of the U penetrates between the two formwork walls (1, 1') of the first panel (a) at the connecting bars (4) and the branches of the U (17 ") penetrate between the formwork walls (1, 1 ') of the second panel (b).
  • These U-bars (17) are preferably introduced, at the factory, between the formwork walls (1, 1 ') on a vertical side of the panels and attached, by means of wire for example (18), to the connecting bars. (4) so as to be maintained when the panel is folded for storage and transportation. Fasteners (18) are generally not made on the last connecting bars (4) of the panel, but preferably on internal connection bars close to the last for reasons of stability of the junction.
  • On the site, a first panel (a) is deployed and the U-shaped bars (17) are placed on the connecting bars (4), the branches of the U (17 ") are disengaged so as to protrude from the vertical side of the panel (a) The second panel (b) is positioned in line with the first one so that the legs of the U (17 ") protruding from the first panel (a) penetrate between the formwork walls (1, 1 ') of this second panel (b). These branches (17 ") are placed on the last connecting bars (4) close to the vertical side of the second panel (b) As in the previous variant, a vertical reinforcing bar (16) is introduced from the top of the first panel (a) in the space between the curved portion of the U (17 ') of the flexible bars (17) and the connecting bars (4).
