Definitions

  • the present invention relates to prefabricated construction parts, such as, for example, beams, lintels, opening frames, studs, formwork elements, chaining, etc., as well as to a process for its manufacture. .
  • the object of the present invention is to provide construction parts, in particular formwork, which can be prefabricated to the dimensions required in the workshop or factory, so as to be able to be mounted directly without requiring handling equipment, and to minimize operations on the site.
  • construction parts which, in accordance with the invention, each comprise several first similar unitary elements, of construction material, assembled end to end and joined, at least on one of their sides, by a plate of material. thermally insulating mechanically connected to each of them by a connection of the tenon and mortise type.
  • a construction part of a given length or height is formed by assembling end to end the necessary number of unit elements which are joined together by the plate of insulating material, which allows the transport of the part on the site. .
  • the first unitary elements are advantageously formwork elements which, assembled form a complete formwork for the lintel or the post, formwork which remains in place.
  • a particular advantage of construction parts according to the invention lies in the fact that they make it possible to meet the standards in force relating to the cracking of coatings. Indeed, these parts intended for the singular points of a building can have thermal insulation characteristics comparable to those of building blocks as described in French patent application No. 2,341,714. In particular, it will be possible to form cells in the unitary elements constituting these parts. This avoids, at singular points, the formation of thermal bridges with temperature gradients likely to cause cracking of the coatings.
  • the unitary elements are made of a construction material chosen from concrete, terracotta, building stones, etc.
  • the second unitary elements when they are provided, can also be made, at least in part , in one of these materials.
  • These second elements forming against-partitions can of course be made of other materials, for example based on plaster. They can even be multilayer elements.
  • the plate of thermally insulating material is made of an expanded plastic material, for example polyurethane foam. Phenolic foam could also be used.
  • the mechanical connection between the insulating material plate and the unitary elements placed end to end is of the tenon and mortise type.
  • This term covers a connection with for example at least one rib or groove of the plate engaged in a groove or rib of corresponding shape formed by the alignment of grooves or ribs of the different elements. These ribs or grooves can be continuous or discontinuous.
  • connection can also be achieved by engagement of pins carried by the plate in blind holes of the unit elements.
  • connection is preferably of the built-in type, that is to say with ribs or nipples having an increasing section from the surface of the plate on which they project.
  • connection may not be built-in.
  • the number of unit elements necessary to obtain a part of a given length is placed in a row and these elements are secured by placing an insulating material, for example by expansion in place of a polyurethane foam or of a phenolic foam.
  • an insulating material for example by expansion in place of a polyurethane foam or of a phenolic foam.
  • the expansion of the insulating foam is carried out in a gap formed between these two rows.
  • Figure 1 shows unitary formwork elements 10 identical to U-shaped assembled end to end and mechanically secured by a plate 11 of thermally insulating material, for example a plate of expanded insulating material.
  • the plate II carries, on its face lla facing the elements 10, ribs 12 in dovetail.
  • Each rib 12 is housed in a groove which is formed by putting end to end grooves 13 present on the outer faces of the loa wings of the elements 10 adjacent to the plate II.
  • Single counter-partition elements 15 in the form of plates of the same length l as the elements 10 are assembled end to end and mechanically secured by the plate 11 on the side of its face llb opposite to the face lla.
  • the plate 11 On this face llb, the plate 11 carries ribs 16 in dovetail. Each rib 16 is housed in a groove formed by the end to end grooves 17 of the faces 15a of the elements 15.
  • Alveoli 14, extending over the entire length of the elements 10, are formed in the parts of these elements not adjacent to the plate 11, that is to say their bottoms 10b and their wings 10c.
  • the elements 10 secured by the plate 11 form a construction part 18 which can constitute for example a formwork for a lintel.
  • the part 18 is put in place and then concrete is poured inside the formwork elements 10.
  • the part 18 is left in place after the concrete has hardened, and a lintel with a counter-partition and a plate is thus obtained. insulation incorporated without thermal bridges between the counter-partition and the lintel.
  • the mechanical connection made by the plate 11 must give the part 18 sufficient mechanical strength to form a formwork allowing, without further reinforcement, the pouring of concrete.
  • the insulator used is a relatively dense insulator having good mechanical properties, for example a polyurethane foam.
  • Formwork elements 10 and counter-partition elements 15 are placed end to end in the required number according to the length desired for the part 18. They are arranged in two parallel rows providing a gap between them, the elements 10 and 15 being placed with their faces provided with grooves facing one another. In the interval between these faces, the polyurethane foam expands.
  • the plate 11 is formed with its ribs 12 and 16. A connection of the tenon and mortise type is then obtained between the plate 11 and each of the elements 10 and 15.
  • connection of this type with ribs 12 , 16 and grooves 13, 17 in profile other than in dovetail, for example in T-profile, or, more generally, with a relief of the faces, facing one another, of elements 10 and 15 suitable for ensuring a mechanical connection with the insulating material after expansion of the latter.
  • the formwork 10 and counter-partition 15 elements are for example concrete elements produced by molding in installations of known type. for the production of blocks. Other materials could be used for these elements, for example terracotta or a building stone.
  • the counter-partition element 15 may be a multilayer element and in particular comprise a fire-resistant layer, for example of plaster.
  • Figures 2 to 5 illustrate other embodiments of construction parts according to the invention.
  • the constituent materials of the elements forming these parts as well as their methods of manufacture and assembly are similar to those described above for part 18 and will therefore not be described below in detail.
  • FIG. 2 shows a part 28 comprising a row of unit elements 20 in the form of frames assembled end to end and mechanically secured on one of their sides by an insulating plate 21, the plate 21 bearing on its face 21a turned towards the elements 20 one or more ribs 22 engaged in grooves 23 of elements 20. On its other face 21b, the plate 21 carries ribs 26 engaged in grooves 27 of elements 25 in the form of plates placed end to end and constituting a counter partition. Cavities 24 are formed in parts of the elements 20 not adjacent to the plate 21.
  • the pieces 20 form formwork elements which, when assembled, constitute a formwork for the casting of a stud.
  • irons 29 can be placed inside the formwork when the part 28 is prefabricated.
  • FIGS. 3 and 4 show a part 38 with first unit elements 30 in the form of frames placed end to end and mechanically assembled by an insulating plate 31.
  • Second unit elements 35 placed end to end are also mechanically assembled by plate 31, on the side opposite that on which the elements 30 are located, and form a counter-partition.
  • Alveoli 34 are formed in parts of the elements. 30 not adjacent to the plate 31.
  • the part 38 constitutes a part framing a door or window, for example a part to be placed vertically against the end of a wall 39.
  • the latter is for example made up of prefabricated blocks 40 with an external bearing part 41 and an interior counter-partition 42 assembled by an intermediate insulating element 43.
  • Such blocks are described in particular in French patent application No. 2,341,714.
  • concrete can be poured inside the formwork formed by the frames 30.
  • a longitudinal groove 44 can be formed on the outer face of the side of the elements 30 facing the blocks 40.
  • the bearing parts 41 of these blocks may have a longitudinal groove 45 facing the groove 44 to form with the latter a cell 46 after definitive positioning of the element 38.
  • the element 38 makes it possible to perfectly satisfy the standards relating to the cracking of coatings. Indeed, although placed at a singular point in the building, this element 38 is not unique, from the point of view of thermal insulation, with respect to the blocks 40. There is then no reason to fear the appearance of thermal bridges at the singular point occupied by the element 38. This remark made for the framing part 38 is of course also valid for the other parts according to the invention placed at singular points of buildings.
  • the part 38 carries sealing tabs for fixing the hinges 47 for the shutter.
  • the plate 31 and the counter-partition 35 are of width less than that of the frames 30 for mounting the window frame 48 and the window frame 49.
  • FIGS. 3 and 4 differ in that, in the case of FIG. 3, it is a frame for a splayed window, while, in the case of FIG. 4, it it is an interior bare window.
  • FIG. 5 illustrates yet another embodiment of a part 58 according to the invention.
  • This part constitutes a window sill and comprises identical unit elements 50 assembled end to end which form the support itself. These elements 50 are secured by an insulating plate 51, as well as second unit elements 55 forming against-partition. Longitudinal cells 54 pass through each element 50.
  • the plate 51 has a thickness greater in its lower part than that which it presents in its upper part and thus has a shape adapted to that of the part 58. In addition, this results in a lightening of the unit elements 50.
  • Irons 53 intended to be embedded in concrete can be placed in a longitudinal groove 56 formed by the end-to-end assembly of grooves 52 provided in the upper face of the elements 50.
  • the length of the unitary elements constituting the parts according to the invention is chosen, for example of the order of one or more tens of centimeters, to allow, by an assembly of a number of these elements, to cover the majority requirements as to the lengths of the parts to be prefabricated in the factory or workshop before their transport to the site.
