  In these drawings, FIG. 1 is an exploded perspective view of a gantry element composed of a simple beam whose opening is oriented downwards and of a single C-shaped post whose opening is oriented towards the outside. FIG. 2 is an exploded perspective view of a gantry element composed of a simple A-beam whose opening is oriented upwards and of a simple A-shaped post whose opening is oriented towards the inside, FIG. in exploded perspective a gantry element composed of a double box girder and a single pole whose opening is oriented towards the inside, FIG. 4 shows in exploded perspective a gantry element composed of a H-section double beam and a single IO pole whose opening is facing outwards, Figure 5 shows in exploded perspective a gantry element composed of a double box-shaped column and a single beam. in a 1 whose opening is oriented downwards, FIG. 6 is an exploded perspective view of a gantry element composed of a double H-section post and a single R-shaped beam whose opening is oriented upwards. FIG. 7 schematically represents a top view of the end of the gantry mounted with the aid of the post and the beam of FIGS. 1 and 4, respectively; FIG. 8 is a schematic view in plan view of the end of the gantry mounted at the end of FIG. 2 and 3 respectively, FIGS. 9 and 10 show schematically in plan view the end of the gantry mounted with the aid of the post and the beam of FIG. 5, and respectively of FIGS. FIG. 6 is an exploded perspective view of a gantry element composed of a double box girder and a double H section pole, FIGS. 12 and 13 schematically illustrate ceiling assemblies using 'a beam e simple in n Q whose opening is oriented downwards, and respectively upwards, Figure 14 is a perspective view of a beam and / or a box-shaped post obtained by the assembly of four identical sections with straight section in Z , the core of each profile forming with each of the two flanges a dihedron whose angle is different from 90 ', and FIG. 15 represents in cross-section a single IQ beam or a single post made of different types of spacers. Referring to the drawings, it can be seen that (Z) a Z cross-section section has been designated by (1), which, when associated with an identical section, is symmetrically disposed opposite each other and constitutes the single section beam at f 2 and ,

  respectively, the section single post in accordance with the invention.

  Each profile (1) Z comprises two longitudinal insoles

  dinales joined by a soul (2), said two soles being each formed of a first wing which is a return of the soul, perpendicular or substantially perpendicular to the soul, and a second wing which constitutes a return of the

first wing.

  In a first variant of construction, the profile (1) Z is symmetrical about the longitudinal axis (la) which extends in the middle of its core (2), its first two wings then having a common width and its two second wings having another common width, so that the two soles

longitudinal are identical.

  In a second and more advantageous construction variant, the profile (1) Z is asymmetrical, one (3) of its first wings then being of a width greater than at least the thickness of the sheet of the profile to

the other first wing (4).

  The second wings, respectively (5) and (6) which constitute

  kill the returns of the first wings, respectively (3) and (4), being oriented substantially parallel to the core (2) and in the same direction as the soul relative to the plane of the first wing of which they each constitute the respective return , for their part have substantially equal heights, the second flange (6) on the narrow sole can however be advantageously a little more

  high that the second wing (5) has on the wide sole.

  The assembly, face to face and symmetrically, of two identical profiles (1) constructed symmetrically, according to the first variant mentioned above, raises no particular observation In contrast, according to their second alternative construction where they are provided asymmetrical, the profiles ( 1) in Z can be brought together face to face and symmetrically in two ways: either by the union of their two second wings (5) belonging to the wide soles, or

  by the union of their two second wings (6) belonging to the narrow soles.

  To form a gantry (or a stem) composed at least partly of a single beam and a single post, formed one and the other

  by the union of two asymmetrical profiles (1) arranged face to face and symmetrically

  it is sufficient to associate a beam of the kind obtained by the joining of two sections (1) by their wide soles to a post of the kind obtained by the meeting of

  two profiles (1) by their narrow soles, and vice versa.

  All posts and beams constructed as just described have in common to present a section in O In any assembly made using a Q-beam according to the invention and a pole in, also in accordance to the invention, to form a stem or a gantry, it will then be noted constant relative provisions, namely that: a) the beams always have their soles wide at the top and their narrow soles at the bottom, the beams obtained according to one or other of the two modes of joining two profiles (1) being then with the opening of the SI oriented either downwards (FIG. 1) or upwards (FIG. 2), and that b) the posts always have their wide soles located on the outermost side to any post / beam assembly, the opening of the IQ being oriented either outwardly of said assembly (Figure 1), or inwardly (Figure 2). The gantry element shown in Figure 1 is formed of a horizontal beam (7) whose opening (8) ú 2 is oriented as just said downwards, and a pole (9) arranged so that the opening (10) of the Q

  is oriented towards the outside of the portico.

  In this construction, the beam (7) rests by one of its two ends, by its first two upper wings (3) on the upper end of the pole (9), the beam then overlapping said upper end of the pole and applying by the internal faces (2 a) of its webs (2) against the outer faces (2 b) of the webs (2) of the post (9). Advantageously, the front edge (7 a) of the beam (7) is simultaneously applied against the first two wide wings (3) of the

post (9).

  The beam (7) and the post (9) thus embedded constitute

  the gantry shown schematically in plan view in FIG.

  The pairs of sections (1) with a cross-section of Z are made in pairs by any known means, for example by bolting or by welding. This joining is however preferably done by bolting, since the sections (1) in Z are generally made from a

galvanized steel sheet.

  Preferably, it is provided by construction that the two profiles (1) of a kind, for example joined by their narrow soles, leave between their second wings (6) which face a space greater than the thickness of the two seconds wings (5) wide soles contiguous in all

  profiles (1) joined together according to the other kind.

  Thus, during the embedding of the beam (7) and the post (9), by overlapping said post by said beam, the second wings (5) present in the upper part of the beam (7) are embedded between the second wings

(6) of the post (9).

  If the space between the second wings (6) of the post (9) does not allow the passage of the second flanges (5) contiguous to the beam, it proceeds to notch of said wings (5) in a zone such that the seconds wings (6) of the post (9) can be closely applied under the first wings (3) of the beam (7) when the front edge (7 a) of this beam itself is closely

  against the first wings (3) of the pole (9).

  The same necking operation of the second wings (6) of the beam (7) and / or the second wings (5) of the post (9) will be performed if necessary, if these respective second wings are in contact and prevent the embedding operation of the beam (7) and the post (9) until its completion This operation will be expected for the first variant of column and beam construction using symmetrical profiles (1); indeed, insofar as the first wings (3) and (4) are then of the same width, the second wings (5) of the post (9) are

  necessarily in the plane of the second wings (6) of the beam (7), and they prevent

  except, of course, to be partially cut, the embedding of the first wings (4) of the beam (7) in the first wings (3) of the post (9). On the other hand, this operation will be useless for the second variant of profile construction (1)

  asymmetrical, since the first wings (4) of the beam (7) can then

  without difficulty in the wide soles of the post (9), the first wings (3) of these

  soles being provided wider than the first wings (4).

  It has previously been indicated that, by construction, it is advantageously provided that, regardless of their kind, symmetrical or asymmetrical, the sections (1) together leave a space between their second wings which

face.

  For this purpose, both for the beam (7) and for the post (9), the two Z-sections (1) are joined by means of spacers arranged in place at regular intervals between one end and the end. other of the two profiles to assemble. These spacers are of the type used to make the assemblies by interlocking two Z section cross section sections described in the French patent application 89 16828 filed by the same applicant. Thus, the spacers may be either U-shaped profiles (19) which extend perpendicular to the general direction (20) of the assembly, each wing (21) of these U being secured to the inner face (2 a). a profile (1) constituting the beam (7), and / or respectively the post (9) to be made (Figures 1, 7 and 15), or a tube (22) of quadrangular section (Figures 1 and 8) , which also extends perpendicularly to the general direction (20) of the assembly, two opposite walls of this tube being made integral with the internal faces (2 a) of the sections (1) constituting the beam (7), and / or respectively the post (9), to achieve. In third variant of spacers, the profiles (1) can be assembled from place to place by means of plates (23) which extend continuously from one first wing (3) to the other first wing (3) on the beam (7), and respectively from one first wing (4) to the other first wing (4) on the pole (9) (Figures 2, 8 and 15); the profiles (1) can also be assembled from place to place by means of plates (23 ') which this time join the first wings (3) or (4) which, both on the beam (11) and on the pole (12). ), form the top of the Il Naturally, on the same assembly, spacers

  of various types (19, 22, 23, 23 ') can be combined.

  Insofar as the width of the U-shaped sections (19) or tubes (22), or the arrangement of the plates (23, 23 '), determines the spacing between two assembled Z-sections (1), and consequently the distance between the second wings facing each other, it is clear that the two variants of constructions mentioned above

  are easily materialized, that of an assembly where the sections are dissymmetric

  by the provision of first wings (3, 4) of different widths, and that of the assembly of profiles (1) Z this time symmetrical, that is to say with their wings (3, 4) likewise width; in all the aforementioned constructions, the spacers ensuring the assembly of the beam (7) are however such, relative to the spacers ensuring the assembly of the post (9), that the distance separating the internal faces (2 a) of the beam (7) is equal to the distance separating the external faces (2 b)

  webs of the sections (1) constituting the post (9).

  Along each beam (7) and each pole (9) to

  the spacers of different types (19, 22, 23, 23 ') provided are advantageously

  bolted on the profiles (1), on the souls (2 a) and on the first wings

  (3) and (4) with which said spacers are in contact.

  In Figure 15 which illustrates the connection of two sections (1) Z for the construction of a single beam or a single post in it, using various types of spacers, the axes of the bolts for assembling two profiles (1) on inner struts (19) U and / or tubular section (22) have been identified by (24), the axes of the bolts for connecting two profiles (1) by plates (23). ) arranged under the bases of & l have been marked by (25), and finally the axes of the bolts for connecting two profiles (1) by plates (23 ') disposed above the top of the f) have been marked by ( 25 ') It is also possible to complete these different connections between profiles (1) using spacers by direct bolting marked (26) at the second wings (5) and / or (6) which are made face under the top of the Q To make it possible to

  such bolting (26), said second wings (5) and / or (6) will be provided with sufficient

he

high.

  The assembly beam (7) / post (9), for the purposes of

  truction gallows or gantry, is itself completed by bolting at the parts of the souls (2) of the beam and the post that are in contact, when the beam overlaps the upper end of the pole and is supported by its front edge (7 a) against the internal faces of the first wings (3) of the pole These bolting are illustrated in Figure 1 by the crosses marked (27) In this figure, it has been represented a pole (9) whose song upper (9a) is horizontal (ie strictly perpendicular to the direction of the pole) and a beam (7) whose front edge (7a) is vertical (that is to say rigorously perpendicular to the horizontal direction in which said beam extends)

  Beam / column then obtained is rigorously orthogonal.

  It is clear, however, that we can easily implement post / beam assemblies other than orthogonal to ensure that each beam (7) extends in a direction inclined by several degrees on the horizontal. For this, and respecting in this respect the inclination to be given to the beam (7) relative to the horizontal, it suffices that the upper end of the post (9) is cut respecting the lines in phantom marked by (28). ) and that the front end of the beam (7) is cut into

  respecting the lines in mixed linesreparated by (29).

  The angle that the lines (28) make with the horizontal is equal to the angle that the lines (29) make with the vertical and is equal to the angle at which the beam (7) will extend relative to the horizontal, once assembled by the bolts (27) at the head of the post (9) The bottoms of the upper flanges of the beam (7) then overlap the end of the post (9) delimited by the lines (28) and the bottoms of the outsoles of the post (9) receive the end of the beam (7)

delimited by the lines (29).

  In all the description that follows, it is obvious

  that one and the other of the two conceivable profile constructions (1) which are asymmetric profiled, with different first wing widths, or symmetrical sections assembled by means of spacers whose width is controlled, apply indistinctly to the other assemblies which are going to given as examples for single beam, single column, double beam and

double poles.

  However, insofar as the constructions obtained using asymmetric Z-shaped profiles (1) are the most advantageous, in particular in that they avoid the notching of the outermost wings (5) and / or (6). in the beam / column assembly, and in particular also in that they lead to more aesthetic constructions, the narrow lower flanges of the beam being embedded in the wide outer soles of the column, it is these asymmetrical profile constructions which will be chosen as examples throughout

  the following description, as well as the figures to which this description refers

refers.

  In these constructions, it may moreover be advantageous

  The brackets (27), as shown in FIG. 16, will be arranged in each corner of the beam / column assembly, on each side of the beam. this assembly, being bolted in the bottom of the first narrow flanges (4) of the beam (7) and in the bottom of the first wide flanges (3) of the post (9), taking in this respect as an example of construction that represented in Figure 1 Both

  Branches of the brackets are then concealed behind the second wings, respectively

  (6) of the beam and (5) of the column, so that they do not

the aesthetics of construction.

  The gantry element shown in FIG. 2 is formed of a beam (II), obtained as was the post (9), and a post (12), obtained

as was the beam (7).

  For the realization of this second gantry, the beam (11) is arranged so that the opening (13) of is oriented upwards and the post (12) is arranged so that the opening (14) of the N is geared towards

inside the portico.

  The assembly of the beam (11) and the post (12) above is such that the beam rests at one of its two ends, by its two

  first upper flanges (3), on the upper end of the post, the beam

  trant then in said upper end of the pole and applying by the faces

  external (2 b) of its souls (2) against the inner faces (2 a) of the souls (2) of the pole.

  By application of the same concept, it is possible to also realize a double beam for the realization of a gantry or a bracket, by assembly with at least one post, said double beam being formed by the meeting of two single section beams in He arranged facing

face and symmetrically.

  From the simple beams (7) and respectively (11), it is thus possible to construct: a box-shaped double beam (15), the two single beams (11) with N-section which constitute it being joined by their first wings (3) composing the base of each fi (Figure 3), an H-shaped double beam (16), the two simple beams (7) section SI constituting it being joined by their first

  wings (3) composing the apex of each N (Figure 4).

  In the same spirit, it is possible to produce two kinds of double posts, constituted by the meeting of two simple posts with D section arranged face to face and symmetrically, namely: a double box-shaped post (17), the two simple posts (9) with section -Q constituting it being united by their first wings (3) composing the base of each f I (Figure 5), a double post H-shaped (18), the two single posts (12) in section N which constitute it being brought together by their first

  wings (3) composing the apex of each A (I (Figure 6).

  The double caisson beam (15) is formed for its lower half of a single beam (11) identical to that shown in FIG. 2. As a result, this beam (15), whose first wings (3) make up the bases of the two assemblies are of a width greater than at least the thickness of the sheet of the profiles to that of the first wings (4) composing the tops of said SÀ, is arranged so that the webs (2) of the four profiles (1) in Z are vertical, and the post that receives it is the post (12) also shown in Figure 2, that is to say the post arranged so that the opening (14) of the L is

  oriented towards the inside of the portico.

  The double beam (15) rests at one of its two ends, by the first high wings (3) of that of its single beams (11)

  which is low, on the upper end of the post (12), the double beam (15) is

  trant then in said upper end of the pole and applying by the outer faces (2b) of the souls of that of its single beams (11) which is low against the

  internal faces (2 a) of the webs (2) of the post (12).

  As has been said above, each Z-profile (1) constituting the double beam (15) and the single post (12) can be provided asymmetrically, the wings (3) being then wider than the wings (4), or symmetrical, the spacers necessary for the assembly being in any event such that the distance separating the inner faces (2 a) of the post (12) is substantially equal to the distance separating the outer faces (2 b) of the cores each single beam (11) in

  Q constituting the double box beam (15).

  In the same spirit, the double beam (16) H (Figure 4) is formed for its lower half of a single beam (7) identical to that shown in Figure 1 Accordingly, this double beam (16) is obtained by the arrangement above the single beam (7) of a second single beam (7), symmetrical with the first, the two single beams being thus joined by the vertices of their D-profiles. The single post (9) and the double beam (16) of FIG. 4 are by construction such that the distance separating the external faces (2b) of the webs of the post (9) is equal to the distance separating the inner faces (2 a) of the webs of each single beam (7), constituting the double beam (16) in H. In the two double-beam constructions which precede, respectively in box (15) and in H (16), the two single beams, respectively (11) and ( 7), which constitute them are linked together by bolting at the level of the first wing s (3) Each of the two constituent simple beams

  of a double beam, respectively box (15) and H (16), is of course

  equipped with spacers, which may be either U (19) or tubes (22) of

  square or rectangular section, or plates (23, 23 ').

  It is clear that in the box beam (15), the plates (23) can serve as spacers for both the lower single beam (11) and the upper single beam (11), the assembly bolts crossing

  then the first wings (3) facing each other and the plate (23).

  In the same spirit, in the H-beam (16), plates (23 ') can serve as spacers for both the lower single beam (7) and the upper single beam (7), the bolts of crossing assembly then

  the first wings (3) facing each other and the plates (23 ').

  These tube spacers, U-profiles, and more

  plates, have the further advantage of improving the mechanical characteristics

  double beams, in particular by increasing their resistance to buckling and

to the twist.

  The gantry element shown in FIG. 5, composed of a single beam (7) and a double box stud (17), is to be compared with the construction shown in FIG. 1, the box (17) being obtained by the assembly of two simple posts (9) arranged symmetrically and united by the first wings (3) which form the bases of each profile in Q In this construction of Figure 5, the distance separating the inner faces (2 a) of webs (2) of the beam (7) is equal to the distance separating the outer faces (2b) of the webs of each single post (9) by forming the double post (17). Furthermore, the beam (7), or the two beams (7) if the double post (17) receives two beams of the aforementioned type, is (are) arranged (S) so that the opening (8) of the SI is oriented downwards, so that each beam (7) rests by one of its two ends by its first two upper wings (3) on the upper end of one of the ux simple posts (9) constituting the box (17), the beam (7) then overlapping said upper end and applying by the inner faces (2 a) of its webs (2) against the

  external faces (2b) of the cores (2) of said single pole (9) concerned.

  The gantry element shown in FIG. 6 is, for its part, closer to the construction shown in FIG. 2. It is in fact composed of a single beam (11) and a double post (18) with an H section. which is itself obtained by the assembly of two single posts (12) linked at their first wings (3) In this construction, the distance separating the outer faces (2b) of the webs (2) of the beam ( 11) is substantially equal to the distance separating the inner faces (2 a) of the webs (2) of each single post (12) by forming the double post (18) and the one or both beams (11) than the post ( 18) is going

  receive are arranged so that the opening of the fl is oriented upwards.

  Each beam (11) is supported by one of its two ends.

  mitted by its first upper wings (3) on the upper end of the double pole, the beam (11) then fitting into said upper end and applying by the outer faces (2b) of its webs (2) against the internal faces (2 a) of the webs (2) of one of the two single posts (12) constituting the double post (18) in H. In all the constructions of FIGS. 3 to 6, it is obvious that the assembly double beam / single pole and that beam assembly

  single / double post is completed by bolting (27) as previously seen

  is lying. Always in the same spirit, one can conceive a construction of gantry or of jib formed of at least a double post and of at least a double beam Two variants are in this respect possible: to any double post in box, it is possible to associate at least one double beam section H, and any double post section H, it is possible to associate at least one

  double box beam, as illustrated in Figure 11.

  Any double pole / double box assembly is also

  completed by bolting (27).

  Finally, it is possible to construct simple columns or beams constituted by the union of two identical sections (30) with a Z cross-section each comprising two parallel longitudinal flanges and joined by a core (31), said two flanges each being formed. a first wing, respectively (32) and (33), which constitutes a return of the core (31) and which is inclined on said core by an angle of between 900 and 130 As in the previous constructions, these profiles (30) comprise a second wing (34) which constitutes a return of the first wing (32, 33) and which is arranged on the same side as the web (31) relative to the plane formed by the first wing Also as in the constructions previous, the two profiles (30) Z are joined together for a simple pole or beam construction being arranged face to face and symmetrically, said single pole or said single beam then having a section It whose sides formed by the two souls (31) of the profiles converge to the top of cetf L.

  Plates (23, 23 ') advantageously serve as

toises with two profiles (30).

  By extrapolation, it is also possible to construct a double post or a double beam (35) (FIG. 14), constituted by the union of two single section posts or of two simple Q section beams arranged face to face and symmetrically united the foundations of these constructions described above can receive

  failures and smooth of the type described in patent application 89 16828.

  The plates bridging such faults or such smooth can then be used at the same time spacers to the posts and / or beams

  designed according to the present invention.

  The single and double beams described above can

  can also be used to support false ceilings.

  For example, from bars (36) which extend between two adjacent beams (7) resting on the lower flanges of these beams, it is possible, with the aid of connecting elements identified by their axes (37). , supporting elements of false ceilings (38) (Figure 12) Joints (39) disposed in said lower flanges prevent thermal bridges Between these joints and the second flanges (6) of the lower flanges, it is also possible cables and

all useful technical conduct.

  In the same way, from T-connection elements (40) whose rod extends between the second wings (6) of a beam (11), it is possible to

  also support elements of false ceilings (41).

  Naturally, the invention is not limited to the modes of application nor to the embodiments that have been described above, and various variants can be conceived without departing from the scope of said invention. , it should be noted as other constants that: in the case of simple column / single beam assembly, one of the two elements of this assembly, either the column or the beam, is open towards the outside of said assembly while the other element is open towards the inside of the assembly; externally, it is necessary here to understand also the top and, from inside, one must also understand the bottom; in the case of double / single beam or single / double beam assembly, the two elements of this assembly are open outwards when the double element is H-section and closed to

  outside when the double element is in box.
