Definitions

  • the present invention relates to a formwork made up of multiple elements assembled for pouring concrete, generally a vertical or formwork formwork.
  • metal formwork offers formwork difficulties and requires the use of formwork oils for demolding.
  • thermoplastic plastic material as in patent DE-A No. 2012032.
  • these panels must be manufactured by extrusion, which limits their dimension in the width direction and does not allow to incorporate reinforcements and assembly means only lengthwise.
  • the form face is made of elastomer behind which a filling of rigid foam of high density plastic material which fills the hollow of the panel is attached.
  • the rear part of the latter is closed either by a metal wall or by a plastic wall, walls which are treated or designed to obtain perfect adhesion with the rigid foam of high density plastic.
  • the edges have sockets whose axes are parallel to the medians of the panels and which are regularly spaced so as to be opposite one another in the assembly of said panels which are then separated by a grid of profiles T-shaped whose core slides between the panels and has holes opposite the corresponding sockets to allow the passage of assembly bolts.
  • edges are trimmed with metal strips perpendicular to the shuttering face, with holes facing the grooves of the panels allowing the introduction of the branches of an assembly clamp.
  • the shuttering face can be obtained, for example, by coating on a support having a flat and smooth surface with a film of polyurethane elastomer forming, after crosslinking, a layer having a hardness of about 90 shores and a density of 1.1-1.2. On this film, while it is still pasty, a layer of polyurethane in the liquid state forming foam is deposited.
  • the rear face 21 to 26 previously manufactured is placed on this assembly, by turning it over. This face is pressed strongly on the flat surface by trapping the polyurethane which, by expansion, will fill the entire volume between the formwork face and the rear face.
  • the expansion of the foam requires approximately 10 min at room temperature.
  • the panel is obtained by injection into a mold of a mixture of polyols and diisocyanates suitable forming a polyurethane foam.
  • a mold of a mixture of polyols and diisocyanates suitable forming a polyurethane foam One chooses formulations forming, in contact with the walls of the mold, a more or less thick skin depending on the temperature and the pressure. In this way, we obtain a panel made entirely of polyurethane.
  • the formwork of the invention has the advantage of being composed of panels of reduced dimensions which are, for example, 2.70 m high and 0.675 m wide, which include a ribbing on their rear faces allowing them to be easily handled .
  • Their weight is generally less than 45 kg.
  • the internal walls of the hollow envelope of hard and flexible material of the plastic panels are treated so as to ensure the attachment of the foam. This treatment is sometimes unnecessary when it is a formwork face which is only made of polyurethane elastomer.
  • the reinforcement grid As for the reinforcement grid, it is composed of rectilinear elements that are easy to install. Finally, the triangular lattice support structure is made of tube and it is very light. The assembly is therefore easily assembled by hand by one or two men, without the need for lifting devices.
  • the panels 1 to 14 of the formwork of the invention each consist of a hollow casing of polyurethane elastomer, the rear face possibly being of polyester.
  • Polyurethane has the advantage of resisting abrasion, tearing, chemicals, oxidation under bad weather and allowing easy formwork.
  • the hollow envelope of the panel comprises a formwork face 15, which corresponds to the shape which one wishes to give to the wall and which is generally planar, a rear rib 16 of reinforcement of the formwork face 15, possibly reinforcements 17, 18 , 19, 20, generally made of steel, inserted into the edges of the panels, and a rear face 21, 22, 23, 24, 26 having recesses 27, some of which 28, 29, 40 have a width narrower at the edge than background.
  • the rear face can be reinforced by a reinforcing strip 62 perpendicular to the recesses.
  • the hollow envelope constituted by the formwork face 15 of the edge reinforcements 17, 18 and the rear faces 21, 22, 23, 24, 25, 26, is filled with a rigid foam of high density plastic material having the property to be compatible and to hang firmly on the envelope.
  • This filling of plastic material advantageously consists of a rigid high density polyurethane foam of the order of 200 kg / m 3 .
  • the edges of the panels 1 to 14 have reinforced edges 61. They may be metal strips 17, 18 profiled which can deviate from each other (fig. 2) and have holes where the claws of the assembly pliers blage, as we will see later.
  • the reinforced edges can also be reinforcements 19, 20 inserted inside the polyurethane foam 31 comprising sockets 32, 33 whose axes are parallel to the medians of the panels 9 and 10 and which are regularly spaced to lie opposite from each other in the assembly of said panels 9 and 10.
  • the shuttering faces 15 extend continuously towards the rear faces 22 which are constituted by plastic material in which is incorporated a glass mast.
  • the formwork further comprises a reinforcing grid formed by profiles 34, 35, 36, 37. These metal profiles are placed at the joint between two panels 1 to 14. They generally have a T-section whose core 38 slides. between the panels and they have holes 39 opposite the corresponding sockets 32, 33 to allow the passage of assembly bolts.
  • edges are lined with reinforcements or metal strips 17, 18, perpendicular to the formwork faces 15 and which have holes opposite the grooves 27 of the panels allowing the introduction of the claws 41, 42 of the branches 43, 44 of assembly pliers 45.
  • a third element of the formwork system of the invention is constituted by the support structures 46, 47 in triangular lattice adapting to the rear of the formwork, and in particular to the profile 34 of the reinforcing grid.
  • These support frames each consist of three uprights 48, 49, 50, the uprights 48 and 49 being connected by horizontal crosspieces such as 51, while the upright 50 is connected to the other uprights by oblique bars such as 52.
  • the structure of the frames 46, 47 is very common in tubular metal construction.
  • the base of the uprights 50 comprises vertical actuating cylinders 53, 54.
  • the uprights 48 are applied against reinforcements 17, 18 or profiles such as 34 thanks to the action of the assembly clamps 45.
  • the weight of the panels 1 to 14, the profiles 34 to 37 and the frames 46, 47 does not separately exceed 45 kg and they can be handled easily by one man.
  • An advantage of the grooves 29, which are wider at the bottom than at the edge, is that they facilitate the grip of the panel 12 by the person who wants to handle it.
  • a groove with a T-shaped section 30 is provided, making it possible to drown the head of a bolt which serves to fix sections or uprights 48 and 49 of the frames 46 and 47.
  • the clamp 45 comprises two branches 43, 44 each terminated by claws 41, 42 intended to engage in the holes of the edge reinforcements 17, 18.
  • the branches 43, 44 are held, at their other end, by the heads 53 , 54 of an axis on the oblique bases symmetrically with respect to the median plane perpendicular to the axis 57 of an eccentric cylinder 58 comprising an operating lever 59.
  • the lever 59 makes it possible to rotate the cylinder 58 around the axis 57 and, in this movement, if the branches 43, 44 are kept stationary, they carry out a successive movement away and closer. In the position of fig. 3 (lever 59 down), the branches 43, 44 are widely spaced.
  • branches 43,44 are brought together and the claws 41,42 come to grip the reinforcements 17,18.
  • the axis 57 is eccentric relative to the outer wall of the cylinder 58. This eccentricity is such that the wall of the cylinder is as far as possible from the claws 41, 42 (fig. 3) when the branches 43, 44 are separated , while the wall of the cylinder 58 is brought closer to the claws 41, 42 when the branches 43, 44 are brought closer (fig. 2).
