Definitions

  • the invention relates to a metal profile intended to be used as participating formwork for the construction of metal/concrete floors.
  • formwork that acts both as the formwork and as the reinforcement is known as participating formwork.
  • this formwork is therefore left in situ as reinforcement and contributes to the in-service strength of the floor.
  • Such formwork is intended to be positioned between two supports, such as bearing walls, resting on them at its ends. Concrete is then poured onto the formwork in the direction of the ribs. After drying, a series of supporting girders is formed, these girders running longitudinally.
  • concrete can be considered to cover any type of binder likely to be used in the construction of flooring.
  • the ribs of the formwork provide anchorage in the transverse direction.
  • embossed or pressed features on the ribs. These features constitute longitudinal points of anchorage between the formwork and the concrete and therefore limit their relative slippage. Specifically, when relative slippage occurs, these embossed features resist the slippage by deforming.
  • the span of the floors is generally 4 meters and the maximum loading that the floor can bear is of the order of 250 kg/m 2 .
  • This profile can thus be used with a smaller amount of concrete than conventional floors, for the same strength.
  • the invention relates to a ribbed metal profile of the participating formwork type for constructing steel/concrete floors, comprising longitudinal corners delimiting upper and lower regions connected by webs and comprising reentrant deformations, characterized in that at least part of each web comprises a reentrant deformation delimited by a continuous line running parallel to the longitudinal direction of the profile and the length of which exceeds that of said part of the web in this longitudinal direction.
  • said deformation extends over the entire length of the web.
  • the profile may also further comprise at least one reentrant deformation in at least part of the upper and/or of the lower regions, which deformation is delimited by a continuous line the length of which is greater than said part of the upper and/or lower regions.
  • said deformation extends over the entire length of the upper and/or lower regions.
  • the continuous line may be broken, symmetric or otherwise, for example crenellation(s).
  • the continuous line may also adopt the form of a sinusoid.
  • the reentrant deformations are present in pairs and symmetrically.
  • the profile may comprise stiffeners in the webs and/or the upper regions.
  • the profile may also comprise bends in the lower regions.
  • the profile comprises, in its webs, a protruding bulge that runs longitudinally.
  • the invention also relates to a method for obtaining a metal profile according to the invention, comprising the following steps:
  • the method may comprise an additional step in which grooves are produced between two implementations of step (b), these grooves, after step (d), constituting stiffeners.
  • the method may also comprise a step of forming longitudinal and protruding bulges which are produced after implementation of step (b), at the deformations intended to be present in the webs.
  • Step (c) may allow the production of reentrant deformations in said webs, on the upper regions and/or on the lower regions of said ribs.
  • the method may also comprise, after step (d), a step consisting in producing stiffeners on the upper and/or lower regions of the ribs.
  • the method may also consist in producing, before or after step (d), at least one bend on the lower regions of the profile.
  • the invention relates to a machine for manufacturing a profile according to the invention, this machine being equipped with at least one pair of rollers of the toothed wheel type, each tooth upsetting metal to form a reentrant deformation.
  • the invention also relates to the application of the profile according to the invention to the production of a participating-formwork floor.
  • the invention relates to a participating-formwork floor obtained with a profile according to the invention, in which at least one brace is arranged in a cavity of the profile, bearing against the protruding bulges.
  • FIG. 1 is a perspective view of a portion of a metal profile according to the invention
  • FIG. 2 is a view in section on II-II of FIG. 1 ,
  • FIG. 3 is a view in cross section of one example of a metal profile according to the invention comprising braces;
  • FIG. 4 illustrates a metal sheet on which the first steps of the method according to the invention have been performed
  • FIG. 5 illustrates the metal profile of the invention, obtained from the sheet illustrated in FIG. 4 , after the last step in the method according to the invention has been carried out;
  • FIG. 6 illustrates another example of a metal sheet on which the first steps of the method according to the invention have been performed
  • FIG. 7 illustrates a profile according to the invention obtained from a sheet illustrated in FIG. 6 , after the last step in the method according to the invention has been performed;
  • FIG. 8 illustrates an example of tooling used for implementing the method according to the invention.
  • FIG. 9 is a perspective view illustrating one example of a brace.
  • FIGS. 1 and 2 illustrate the same portion of a profile according to the invention.
  • This metal profile is ribbed, which means that it has a series of substantially parallel ribs running longitudinally.
  • FIGS. 1 and 2 illustrate one of these ribs 1 .
  • the profile comprises longitudinal corners, upper corners 2 and lower corners 3 . These corners between them delimit zones known as regions, upper regions 4 and lower regions 5 .
  • these webs run obliquely, such that the transverse width of the cavity 10 , at the lower regions 5 is greater than that of the upper region. This then is a profile called an “open” profile, which is stackable.
  • the invention is not restricted to this embodiment and also covers profiles known as “closed” profiles, which are not stackable.
  • the webs could also run perpendicularly between the upper and lower regions.
  • the profile according to the invention comprises, in each web 6 , a reentrant deformation 60 which is produced substantially in the lower zone of the webs.
  • Reentrant deformation is understood to mean a deformation which displaces the sheet metal of the profile toward the inside of the cavity 10 .
  • These deformations are delimited by a continuous line which, in the embodiment illustrated, runs in a middle zone of the web and which has a crenellated shape.
  • the crenellation illustrated in FIG. 1 has an oblique shape, which means that the segments 62 connecting the segments 61 which run in the longitudinal direction are oblique and not perpendicular to these segments 61 .
  • Other shapes could be chosen for these reentrant deformations made in the webs 6 of the profile.
  • the line delimiting these deformations prefferably have a continuous shape, for this to extend over at least part of the web and for this line, in the plane of the web, to be in two dimensions. That means that the reentrant deformation formed in a web cannot be a simple longitudinal line or a line perpendicular to this longitudinal line, for example connecting the upper and lower regions 4 , 5 .
  • the developed length of the line delimiting the deformation is greater than the part of the web on which the deformation is produced.
  • the deformation 60 produced in the web 6 creates, on the inside of this web, two parts delimited by the crenellated shape and transversely separated from one another by the depth of the deformation produced.
  • a wall 65 which is substantially perpendicular to the parts 63 and 64 .
  • the depth of the deformation corresponds more or less to the height of this wall which has the form of a continuous three-dimensional crenellation.
  • FIGS. 1 and 2 shows that the upper part 63 of the web 6 has a bulge 66 which runs longitudinally above the segments 61 closest to the upper region 4 and which is continuous.
  • This bulge constitutes a projecting or protruding deformation, which means a deformation which displaces the sheet metal of the profile toward the outside of the cavity 10 .
  • the benefit of this bulge will be described later on in the description. It can be omitted.
  • the line delimiting the deformation 60 may therefore be defined as the one that forms the intersection between the part 63 and the wall 65 . It is therefore in two dimensions in the plane of the part 63 , here referred to as the “plane of the web”.
  • This line can be located at any level along the web. However, for preference, it is not situated on the top corners 2 . This is because any deformation of the profile at the top corners considerably reduces its strength and is to be avoided.
  • FIGS. 1 and 2 show a profile comprising a single reentrant deformation in each web.
  • Other profiles could have two, or even three reentrant deformations.
  • this continuous two-dimensional line makes it possible, when the sheet metal is being deformed, for metal to be displaced across the width of the sheet.
  • This displacement of the metal limits the thinning of the sheet at the point of deformation and therefore makes it possible to create deformations of a greater depth than can be achieved with known metal profiles.
  • the metal profile according to the invention comprises, in its lower 5 and upper 4 regions, deformations 50 or 50 , and 40 , 41 .
  • these reentrant deformations also have the shape of oblique crenellations, like the deformations 60 provided on the webs 6 .
  • the deformations 40 and 41 are symmetric about a longitudinal line 42 passing through the center of the upper region 4 .
  • the profile according to the invention could have just one deformation or could even have three deformations in the upper and lower regions.
  • the figures also show that grooves are made in the profile, both in the webs 6 and in the upper region 4 , to produce stiffeners 67 , 43 , 44 . These are reentrant deformations.
  • stiffeners In the conventional way, the purpose of these stiffeners is to enhance the mechanical strength of the profile according to the invention.
  • FIG. 3 illustrates a profile according to the invention of the kind illustrated in FIGS. 1 and 2 and which comprises a central rib 30 flanked by two half-ribs 31 and 32 .
  • FIG. 3 shows that inside the cavity 38 defined by the rib 30 there may be a brace 33 which bears against the upper zone 650 of the walls 65 and on the bulges 66 which are of significant depth.
  • a brace 37 is provided in the cavity 38 defined by the half-rib 32 .
  • the upper zone 650 of the walls 65 is an oblique wall, facing toward the inside of the rib 30 with respect to the upper part 63 of the web 6 , and they are therefore each able to accommodate the end of a brace 33 , 37 in the form of an arched buttress.
  • the bulge 66 present between the upper part of the web and the upper zone 650 creates a space making it easier to fit a brace and increasing the brace bearing area.
  • this brace can be used for attaching elements of the false ceiling, once the floor has been created using the profiles according to the invention as formwork.
  • These elements may notably be pipes or cables.
  • the weight of the suspended elements tends to pull the brace downward.
  • the brace therefore exerts a lateral thrust toward the outside of the cavity, reinforcing the cohesion between the profile and the concrete poured into the profile.
  • the braces have screwthreads 330 , 370 intended to accept screws for attaching these elements. These screwthreads protrude from the surface of the brace 33 and are within the thickness of the brace 37 .
  • FIG. 9 illustrates one example of a brace 39 , with screwthreads 390 , which brace can be positioned in the cavity of a profile according to the invention.
  • FIGS. 4 and 5 illustrate steps in one example of how to implement the method according to the invention.
  • This method first of all consists in flattening a metal sheet of set thickness of between 0.6 and 2 mm.
  • the next step involves producing two reentrant deformations 60 , one on each side of a longitudinal and central line 52 of the sheet. These deformations are similar to those illustrated in FIGS. 1 and 2 .
  • two deformations 40 , 41 are then made, these deformations likewise being arranged symmetrically about the longitudinal line 52 , but further away from this line than the deformations 60 produced in the first step. These deformations are similar to those illustrated in FIGS. 1 and 2 .
  • the bulge 66 is then produced at each deformation 60 . It is a projecting or protruding deformation so that it enlarges the cavity defined by each rib, in the finished profile.
  • grooves 67 and 43 , 44 are made in the sheet.
  • these grooves will form the stiffeners illustrated in FIG. 2 in particular. They are reentrant like the deformations 60 , 40 and 41 .
  • stiffeners 67 need to be produced while the metal sheet is still flat.
  • the grooves 43 , 44 could be produced after the profile has been bent into shape to obtain the ribs.
  • the final step in the method is to deform the profile in order to obtain substantially parallel longitudinal ribs.
  • the profile obtained comprises two half-ribs 31 a and 32 a the webs 6 of which have deformations 60 .
  • the lower region 5 of the profile is centered on the central longitudinal line 52 of the sheet and the deformations 60 are situated in the webs 6 of the half-ribs 31 a an 32 a and the deformations 40 , 41 are situated in the their upper region 4 .
  • FIGS. 6 and 7 illustrate another example of how to carry out the method according to the invention.
  • the method here consists in producing, symmetrically about a longitudinal central line 52 of the sheet, two reentrant deformations 50 and 51 . After this first step, deformations 60 are produced in the sheet, symmetrically about the line 52 , but separated from this line.
  • the later step in the method consists in producing deformations 40 , 41 . These deformations are also symmetric about the central line 52 and are further away therefrom than are the deformations 60 .
  • All the deformations 40 , 41 , 50 , 51 and 60 are similar to those illustrated in FIGS. 1 and 2 .
  • bulges 66 and grooves 67 and 43 , 44 are also produced in the sheet.
  • the last step in the method is to deform the sheet in order to obtain the two half-ribs 31 b and 32 b.
  • the deformations 50 and 51 are situated in the lower region 5 of the profile. Moreover, the deformations 60 are situated in the webs of the profile while the deformations 40 , 41 are situated in the upper regions 4 of the profile.
  • the width of metal sheet used depends on the number of ribs and on the height of the profile that is to be obtained.
  • each reentrant deformation corresponds to a metal sheet width reduction of between around 1 and 1.5 mm.
  • the profile produced from a metal sheet with a starting width of 400 mm has a width of around 395 mm.
  • FIG. 8 illustrates tooling that can be used to obtain the crenellated deformations illustrated in the various figures.
  • This tooling is made up of two pairs of rollers 70 , 71 and 72 , 73 capable of rotating in opposite directions and between which the sheet that is to be deformed can be fed.
  • one roller 70 , 72 has a profile 700 , 720 which complements that 710 , 730 borne by the roller 71 , 73 of the other pair, these profiles intermeshing in order, in a metal sheet, to create two symmetric reentrant deformations like the deformations 50 and 51 of FIGS. 6 and 7 .
  • the two pairs of rollers are separated from one another from a central position so as to produce the reentrant deformations, in pairs, and symmetrically about the center of the sheet.
  • Tests conducted showed that the method according to the invention makes it possible, for a given thickness of sheet metal, to produce deformations the depth of which is greater than the deformations exhibited by known metal profiles.
  • the reentrant deformations of a profile according to the invention have a depth greater than 3 mm and which can be as much as 5 mm for a metal sheet around 0.75 mm in thickness.
  • a conventional profile of the same thickness had deformations obtained by pressing and the depth of which is between around 2 mm and 2.5 mm.
  • the depth of the deformations may be between 6 and 7 mm for a metal sheet 1.5 mm in thickness.
  • the deformation obtained using the method according to the invention has a greater depth.
  • the displacing of the metal toward this longitudinal central line is also a by-product of the shape chosen for the deformation. It will be recalled here that the deformation is delimited by a line running longitudinally and continuously and of which the projection in the plane of the sheet (or alternately of the web) is in two dimensions.
  • the first profile (No. 1) is a conventional profile comprising, in its webs, pressed features in the form of oblique segments. Such a profile is notably manufactured by the Bacacier company under reference H60.
  • the second profile (No. 2) is a profile according to the invention which has reentrant deformations only in its webs (one deformation per web), these deformations being of the type illustrated in FIGS. 1 and 2 .
  • the third profile (No. 3) is also a profile according to the invention, like the one illustrated in FIG. 5 , i.e. comprising reentrant deformations both in its webs and in the upper region.
  • Profiles 1 to 3 also have three longitudinal bends along their lower regions, like those referenced 53 in FIGS. 4 and 5 .
  • the tests involved positioning each beam obtained from the four profiles on a press.
  • This press is a hydraulic press of the Ralich type with a power of 30 metric tons, with a pneumatic ram 125 mm in diameter.
  • Each beam is positioned centrally in relation to the press ram and rests on each end on two metal blocks.
  • the press is fitted with a pneumatic pressure gauge marked from 0 to 12 bar, with a manual distributor.
  • a comparator is positioned under the beam being tested, in a central position, with its needle pointing to 0.
