Definitions
- the present invention relates to the field of the manufacture of concrete slabs or slabs poured into place by means of shuttering panels. More particularly, the invention relates to panels for the production of these slabs or slabs, the assembly of such panels and the method of producing such concrete slabs or slabs.
- the method of manufacturing cast concrete compression slabs in situ comprises a shoring system consisting of props and beams connecting the struts to each other.
- Formwork plates are then placed on the beams and are provided with a smooth and oiled upper face called formwork face allowing the formwork of these plates from the lower level after hardening of the concrete.
- the rough surface condition of the raw concrete does not allow to paint it directly, it is necessary to apply at least two layers of smoothing plaster before painting.
- Reusable formwork panels which are usually plywood or polymeric panels, degrade and deform as reuse occurs, resulting in a deterioration in the quality of the finish of the ceilings as they are made. progress of the site. This results in an increase in the duration of patching work and sanding ceilings before the application of the coating and then paint.
- a usual method consists in setting up pre-slabs, that is to say prefabricated concrete slabs in the factory or in fairground prefabrication. Once positioned on the formwork area of the floor, the slabs serve as a formwork floor for pouring a complementary concrete thickness collaborating with the predalle.
- This method makes it possible to use a simplified shoring system because the slabs have a clean structural strength and incorporate part of the reinforcement of the compression slab.
- the major disadvantage found on the predalles system is the treatment of the joints on the underside of these.
- the joint is treated with a suitable coating but inevitably there are superficial cracks between the slabs due to the removal of the concrete.
- the slabs are also heavy and expensive to transport. They require large storage areas on site.
- the implementation of embedded networks slab is complicated because the volume of concrete cast in place is less compared to a compression slab completely cast in place.
- the underside of the slabs is made of raw concrete and can not be painted directly for the reasons mentioned above, the application of a filling coating and mandatory before painting.
- a first object of the invention is to overcome the problems of safety, ergonomics and quality of finish during the production of compression slabs forming floor in the field of construction.
- Another object of the invention is to provide formwork panels for the realization of such concrete slabs forming floor.
- the present invention relates to a lost formwork panel for producing a concrete floor slab, said panel constituting, in the poured state of the slab, the lower part of said slab, characterized in that the panel present :
- This lost formwork panel therefore cooperates with the compression concrete slab poured above it, throughout the life of the structure.
- Slab here refers to both a slab made directly on a construction site, and a prefabricated slab factory and transported to the construction site. The implementation of such a panel makes it possible to eliminate the stripping operation, the time and the associated constraints. In addition, thanks to the structure of the upper face of the panel the concrete, after its grip, adheres to said panel and the underside of said panel does not require the application of plaster before painting.
- the shuttering panel according to the invention does not participate in the structural dimensioning of the concrete slab. This is what differentiates it from a predalle.
- the shuttering panel according to the invention remains integral with the slab and serves as a finishing coating of the underside of the slab.
- the hooking means of the upper face of said panel may be cavities in the form of undercut, such as cells shaped dovetail.
- the pouring of the slab, or of the pre-slab requires the assembly of several panels according to the invention comprising connecting means between them.
- These means for connecting to an adjacent panel may include means for direct engagement with said adjacent panel, such as complementary rabbets or tongue-and-groove shapes.
- the connecting elements may comprise connector-type elements, which will be detailed later in the description.
- the underside of said panel comprises chamfered edges or thinned edges, constituting housings for the application of a jointing compound and possibly an anti-cracking band. between two adjacent panels, which allows to obtain a finish without visible joint and without extra thickness.

- the underside of said panel is made of a material having a porosity and / or a capillarity also allowing its recovery by a coating and / or a paint.
- the panel is formed of a monolithic block, preferably made of a material based on MgO, MgCl 2 and fibers.
- the fibers are flush with the surface of at least the upper face of the panel to form the rough face of adhesion of the concrete.
- This material based on MgO, MgCl 2 and fibers is sufficiently porous to allow, by capillarity, the adhesion of a paint for example.
- the panel comprises a core comprising a thermal insulating material and / or imparting acoustic insulation properties to said panel.
- the core of said panel may be surrounded by an upper layer and a lower layer each formed of a material comprising fibers embedded in a binder, preferably said binder of the upper layer comprising an elastomeric polymer, such as that a polymer of latex or styrene-butadiene type, preferably the binder of the lower layer comprising a material comprising magnesium oxide and magnesium chloride.
- a binder preferably said binder of the upper layer comprising an elastomeric polymer, such as that a polymer of latex or styrene-butadiene type, preferably the binder of the lower layer comprising a material comprising magnesium oxide and magnesium chloride.
- the polymer of the topcoat may be an EVA latex polymer emulsion ethylene-vinyl acetate (C 4 H 6 O 2-C 2 H 4) n) or type SBR styrene-butadiene (C 8 H 8 .C 4 - H 6 ) n, optionally mixed with a hydraulic binder such as portland cement
- the fibers mentioned below may be of any type, but are advantageously glass fibers.
- the panel according to the invention is not a structural element of the slab, it has a main role of supporting poured concrete on its upper face. As a result, as mentioned above, its thickness is less than a traditional predalle.
- the thickness of the concrete above is large enough to embed reinforcement, electrical connection ducts, hydraulic or aeraulic.
- At least the upper face of the panel of the invention has means for receiving elements such as housings and / or sheaths of electrical and / or hydraulic connections, said elements being preferably suitable. to be removably mounted to said upper face of the panel.
- receiving means can then advantageously be arranged projecting from said upper face, such as clamps of the type of cable ties, collars or self-gripping coatings, or be in the form of grooves formed in the upper part of said panel.
- At least one of the faces of said panel may be provided with marks and / or traces able to position it as a formwork on the site and to guide the positioning of ancillary elements: - on the upper face, elements intended to be incorporated into the concrete to be poured on said panel, such as reinforcements for concrete, housings and / or electrical, hydraulic and / or air ducts, door and window locations, thermal breakers or balconies,

- Figure 19 is a top view showing different marks and traces on the upper face of a panel assembly according to the invention.
- the panel 1 according to the invention is a formwork panel of rectangular shape whose mechanical characteristics are dimensioned so as to withstand a point load such as the passage of a man flowing on the formwork before pouring the concrete and withstand the thrust of the concrete as it is poured.
- the bending strength of the panel depends on the span between the structural beams 3 supported by vertical struts 2 of the shoring device provided in the context of its use. This flexural strength is adjusted by modulating the thickness of the formwork panel according to the shoring system used. The allowable deflection between beams 3 is calculated according to the permissible tolerances of a finished ceiling in the building area.
- the material forming the formwork panel 1 advantageously has a high dimensional stability, in particular a maximum expansion or shrinkage of preferably 0.2% when it is subjected to the maximum hygrometry and temperature variations observed in the zone where the device is implemented. In particular the material has a maximum expansion or shrinkage of 0.2% when it is coated with concrete in the liquid state.
- the material constituting the shuttering panel according to the invention is a composite material consisting of a mineral body 5 formed by the agglomeration of magnesium oxide (MgO -30% to 60%), magnesium chloride (MgCl 2 -20% to 50%), and perlite (Fe 3 C - 3% to 15%).
- the upper 4 and lower 6 faces (see Figure 4) comprise a layer of woven or nonwoven glass fibers. These two layers of glass fibers are embedded in the matrix of the body of the panel.
- the face called “lower face” 6 ( Figure 3) of the shuttering panel 1 is that which is placed below when the panel is placed on the beams 3 of the shoring device.
- the formwork panel according to the invention is characterized by a healthy, smooth, regular lower face 6 which in particular meets the requirements of adhesion capacity with all types of water-based paints used in common surfaces in buildings used for dwelling.
- the surface has porosity and capillarity adapted to the grip of such paint.
- the aforementioned mineral composite material responds in particular to these constraints of paint adhesion and regularity of the lower face 6.
- a lower face 6 of the shuttering panel produced by means of this composite material has a water absorption capacity of between 5% and 30%, preferably close to 20%, and a light color (reflection factor of the surface of at least 70%) allowing its painting in two color layers.
- the panel 1 of formwork lost according to the invention has on its four slices connecting means to adjacent panels, to ensure continuity between several panels of identical design assembled end to end.
- the connecting means make it possible in particular to ensure the flatness between the panels 1 in order to match the flatness requirements of the supports ready to paint and serve to ensure the tightness so that the concrete can not flow between the panels 1.
- the connecting means allow for example the following assemblies:
- the panel then has tenons or lamellae 12 distributed at regular intervals on two contiguous slices and reservations 13 of complementary shape, cut in the slice and located exactly at the same intervals on the other two slices. These appendages are dimensioned so as to form an interlock when several panels 1 are joined one beside the other to form an infinitely expandable assembly (FIG. 1). This assembly is less tight than the previous between the panels 1 during the pouring of the concrete. There is then provided a chamfered upper edge 15 on all the edges of the upper face ( Figure 8). These chamfered edges 15 serve as a reservation for the application of an elastomeric sealing gasket after assembly of the panels on the site of the formwork.
- the panel 1 then has complementary rebate edges 10 and 1 1 respectively formed at the top face for two contiguous edges (example of the rabbet 11) and at the lower face for the other two edges (example of the rabbet 10).
- these forms allow to cover a rabbet on another rabbet of opposite shape.
- the interlocking makes it possible to guarantee a precise adjustment and flush of the panels 1 adjacent to each other and compensates for any adjustment faults of the shoring device.
- This assembly ensures hermetic sealing between the panels and thus avoids the flow of concrete between the panels.
- connectors 18 The assembly by means of "connectors" 18 (see Figures 12, 13, 14) which are distributed on two contiguous edges of each of the panels to be assembled.
- the connectors 18 comprise a conical-shaped foot fitting 19 to an inverted V-shaped housing formed between the lower edges of the adjacent panels.
- This foot 19 is surmounted by a rod 20 housed in the reservations 17 (see Figures 10 and 1 1) formed in the edges of the panels, and ending with a head 21 resting on the upper face 4 of the two panels adjacent.
- the reservations 17 formed in the edges of the panels make it possible to define the precise positioning of these connectors 18 and ensure that the connectors are held in place at their predefined position on said panel.
- These bookings 17 in the songs allow to adjust the panels 1 against each other without any gap, thus ensuring maximum sealing when pouring fresh concrete (see Figure 13).
- edges of said panel which are devoid of connectors also have reservations whose shape is designed to match the shape of connectors fixed on another identical plate when these two plates are positioned side by side, whether in the widthwise or in the direction of the length, the panels assembled together being always oriented in the same direction. These reservations can then also act as a key during the assembly of panels on the site.
- the shape of the connectors 18 is designed to allow the superposition of the panels during storage: the base of the foot 19 is recessed to receive the conical or rounded head 21 of said connector and thus allow the assembly stack of panels with connectors.
- the upper face 4 (see Figure 2) of the lost formwork panel 1 according to the invention has means for hanging with the concrete slab after curing.
- Fastening with concrete can be created in several ways: - one or more non-emergent reservations 7 (shown diagrammatically in FIGS. 2, 4, 8, 9) are cut in the upper face 4 of the lost formwork panel 1.
- the (or) bookings have an undercut shape, preventing a hardened liquid body from loosening. It may be a dovetail shape with a trapezoidal profile (as shown diagrammatically in FIGS. 2, 4, 8 and 9) whose broad base is located in the bottom of the reservation or any other profile presenting a widening compared to the width measured at the surface of the panel.
- the assembly of the appendage (s) to the shuttering panel can be achieved by gluing, mechanical fastening, or assembly of complementary shapes. This type of assembly is preferred when the thickness of the panel is too low to make a reservation in the material of the body of the panel.
- the hooked appendage (s) may also serve as a wedge for laying a possible sheet of metal reinforcements on the formwork which will be coated during the pouring of the concrete and form a reinforced concrete.
- the appendix then allows to maintain a distance of a few centimeters (for example 2 to 5 cm) of concrete coating between the lost formwork panel and the reinforcing ply.
- the grouting may for example be carried out in two ways: the four edges of the lost formwork panel are thinned edges 16, on the lower face 6 (FIG. 3) only, for example from a depth of one to three millimeters and on a width of not more than sixty millimeters.
- the end-to-end implementation of the thinned edges 16 of two adjacent formwork panels provides a reservation allowing the subsequent laying of a crack-proofing strip glued and coated in several passes with a coating adapted to the support material without generating apparent extra thickness. the naked eye.
- the tape is stuck in the reservation created by the thinned edges 16 (see FIG. 9) of each of the two adjacent assembled panels.
- the four edges of the lost formwork panel are chamfered edges 14 on its lower face 4 (FIG. 8).
- the chamfer has an open angle, preferably greater than 45 ° in order to provide a maximum hooking surface for the filling compound.
- the reservation formed by the end-to-end insertion of chamfered edges 14 of two adjacent panels allows the subsequent application of a specially dedicated filling plaster. After drying the filler, it is possible to apply a finishing coat to permanently mask the junction between the two panels.
- the lost formwork panel according to the invention 1 can be placed at the bottom of the formwork on the marble of an industrial prefabrication bench or fairground. After dismantling the slab, the formwork panels cooperate with it permanently and irreversibly. They thus serve as a permanent finishing coating of the underside of the prefabricated slab. This arrangement makes it possible to directly paint the underside of the prefabricated slab without a step of prior preparation of the support.
- the panel 1 comprises a core 22 comprising a thermal insulating material and / or imparting acoustic insulation properties to said panel, interposed between an upper layer 24 with a rough upper surface 4 and a layer lower 26 with lower face 6 ready to paint.
- Each of the upper 24 and lower 26 layers may be formed of a material having fibers, such as glass fibers, embedded in a binder.
- the binder of the upper layer 24 may comprise an elastomeric polymer, such as a polymer of latex or styrene-butadiene type, optionally mixed with cement, such as Portland cement.
- the binder of the lower layer 26 may be a material comprising magnesium oxide and magnesium chloride.
- the core 22 may be formed of a high resilience material whose acoustic absorption coefficient aw is greater than 0.10 (according to ISO 1 1654) for sound frequencies ranging from 0 to 40000 Herz.
- the mass of the top is constituted by the concrete which usually has a density of 2.4 to 2.8
- the bottom mass is the lower layer 26 of the shuttering panel 1 with a density greater than 1.
- the panels 1 may advantageously be equipped on their upper face 4 and / or on their lower face 6 with means for receiving elements such as housings 30 or sheaths 31 for connections. electrical, hydraulic and / or a somehowlic, said elements being preferably adapted to be mounted removably to said upper face 4 of the panel.
- these panels may be pre-equipped with reception means arranged projecting from said upper face 4, such as clamps 25 of cable-clamp type, necklaces or self-adhesive coverings.
- grippers for example in the form of self-gripping pads glued to the surface: the housing bases 30 also having self-gripping areas can thus be positioned quickly, accurately and removably.
- Said receiving means may also be in the form of grooves in the upper part of said panel.
- pre-equipment panels 1 and allows a positioning casings 30 formwork and ducts 31 connection and accurate fast because it does not require the reading of a plane and the measurement by manual measuring means (tape measure); This positioning of the formwork boxes on the panels 1 remains nevertheless flexible because it can be, if necessary, shifted by a few millimeters to bypass reinforcement for the concrete.
- the housings 30 can also easily be detached and then put back in place.
- At least one of the faces of said panel may be provided with markers 27 and / or plots 28, 29 (see FIG. 19) able to position it as a formwork on the site and to guide the positioning of the panel.
- markers 27 and / or plots 28, 29 see FIG. 19
- elements intended to be incorporated into the concrete to be poured on said panel such as reinforcement for concrete, electrical networks, hydraulic and / or aeraulic, locations of doors and windows, thermal breakers or balconies,
- each plate is identified by a numbering 27 which corresponds to the order of laying and refers to a plane.
- the plots 28 correspond to the real implantation in space and to the actual scale of the reinforcement, networks and boxes 30 which must be incorporated in the concrete slab and put in place before it is poured. All these markers and traces serve as a guide for the operators to position the material to be incorporated in the slab.
- the assembly of the shuttering plates then forms a puzzle (figure 19) on which all the information useful for the construction of the building appears in the form of a level plan of the building on a real scale.
- the operator no longer needs to refer to a paper plane, nor to use measuring tools to position the various elements. Errors in measurement and positioning are then considerably reduced or eliminated. It also results in a huge time saving on the construction site.
