Description

The present invention generally relates to the elements to be

  implement for the construction of a scaffold on the made of any construction to be treated, in particular for the realization or the refection of the cover thereof. It is aimed more particularly, but not necessarily

  exclusively, consoles implemented for the establishment

  a guardrail, and possibly a floor,

  along such a cover, or on it.

  More specifically, the present invention relates to

  where the case, for subjection to it of any

  another scaffolding element, a rod or candlestick

  de-corps for example, or another scaffolding console,

  such a scaffolding console comprises, on the one hand, an

  end, on which said other scaffolding element can, for its location, be engaged, in practice by simple interlocking, and, secondly, transversely relative to said tip, for locking in position of said other

  scaffolding element, at least one piercing specific to the implan-

  any holding means, pin, for example,

ple, through this one.

  Such a scaffolding console is for example described in the French patent application filed on 14

  April 1975 under No. 75 11494 and published as N02.307.937.

  In practice, in this French patent application, the

  piercing thus associated with a tip directly affects, itself

same, said tip.

  As a result, this endpiece has to ensure by itself a dual function, of localization, and of maintenance, for

  the scaffolding element likely to be engaged on it.

  This provision has given and can still

  faction, at least for some applications.

  But it has the disadvantage of subjecting the tip to

  important demands when the element of scaffolding

  engaged on it is itself the object of some

charge or any shock.

  Or it is most often a tip attached by simple welding on any cross supports

  The solicitation of which he may be the object

  it is evident that it is connected to its support cross-member, and the weld that provides this connection can itself be the object of a shearing action detrimental to its integrity. For safety reasons, it is therefore necessary, in such a case, to seriously strengthen such a nozzle and its welding,

  price of a complication for the whole.

  The present invention has a general purpose object a provision to avoid very

simple this drawback.

  More specifically, it relates to a scaffolding element, in particular a console, of the type comprising, for securing to it any other element, on the one hand, a tip on which said other element can,

  for its location, to be engaged, and, on the other hand,

  towards said nozzle, for the locking in position of said other element, at least one clean bore

  to the implantation of a holding means, pin for example

  through the latter, this scaffolding element being generally characterized in that said drilling

  is established at a distance from said tip.

  For example, the tip extending projecting on a

  any support crossbar, from a first side of this

  here, the piercing affects another organ, a section of tube

  for example, also protruding from the said work.

  pouring support, but on the other side of it.

  There is thus an advantageous separation between the functions

  location and maintenance requirements, the function of

  of location being the only one ensured by the sleeve,

  say that the hold function is supported

  by another body associated with it.

  The sleeve is advantageously provided.

  In addition, a double commitment being ensured,

  that of the other, enters, on the one hand, the element of scaffolding

  reported, and on the other hand, the scaffolding element

  carrying the latter, the influence of the first on the second is

  it has been advantageously extended, for the benefit of security.

  The features and advantages of the invention

  will come out from the following description, & ti-

  for example, with reference to the schematic drawings anne-

  in which: Figure 1 is an elevational view of a scaffolding element according to the invention;

  Figure 2 is a larger scale, a view par-

  view illustrating the commitment, on such an element of scaffolding

  ge, another scaffolding element according to the invention;

  FIG. 7 is a view which partly reflects this

  the Figure 1, relates to an alternative embodiment of the scaffolding element concerned;

  FIG. 8 is, on a larger scale, an analogous view

  to Figure 7, for another variant of

  lisation; FIGS. 9 and 10 are partial cross-sectional views of this alternative embodiment, respectively along lines IX-IX and X-X of FIG. 8e.

  These figures illustrate, by way of example, the applica-

  invention to a scaffolding console 10 of the kind

  including, in the aggregate, an amount 11, a cross-reference 12

  square on the upright 11, at the upper end

  re of it, and triangulation means 13 connecting

  said support cross member 12 to said post 11.

  In practice, in the embodiments

  11, the upright 11 and the crosspiece 12 are both constituted by sections of metal tube section

  square cross-section, suitably joined one to the other

  by welding, in the angle they form between them.

  Furthermore, in these embodiments, the tube section forming the cross member 12 is open at one and the other of its ends, and, at a distance from such an end, it has, transversely, one or more bores. 14 Suitable for the installation of any holding means,

a pin for example.

  Following provisions which, well known in

  same, and not part of the present invention, will not be described in detail here, it is thus possible to engage at one or other of the ends of the cross 12, as shown schematically in broken lines for one

  of them in Figure 1, an attachment arm 15, which itself

  same carrier of a hooking finger 16, allows the hooking-

  of the assembly to any fastener, usually called

  safety hook, provided for this purpose on the construction

  repaired, said latching arm 15 being well

  heard on said cross-member 12 by one or more

  pins installed in favor of holes 14

of these.

  In view of the above, the tube section

  the amount 11 is closed at one of its

  mits, which is the upper end, by the cross 12. By cons, At its other end, which is so

  the lower end, or foot, it is open.

  It thus forms, at its foot, a sleeve 18.

  For reasons which will appear hereinafter, it carries, in extension of this sleeve 18, downwards, two flanges 19, which are for example reported by welding, such as

  represented, and in each of which is arranged, one in

  correspondence with the other, away from said sleeve 18, and

  transversely to it, a bore 20 pro-

  pre to the implantation of any means of maintenance, a

pin for example.

  In the embodiment shown in FIGS.

  1 to 6, the triangulation means 13 comprise, of a

  part of a tube 22 which, comparable to those

  killing the amount 11 and the cross 12, is reported to those

  ci, for example by welding, in the angle that form between them these tube sections, extending at 450 relative to them, and, secondly, two sections of section section T 23, which, each disposed respectively on either side of the tube section 22, at the end thereof opposite to said angle, being properly secured to this tube section 22, for example by sounding, connect said section of tube 22 one to the amount 11, the other to the cross 12, being also properly secured,

  for example by survey, audit amount 11 and the aforementioned

pays 12.

  In practice, at their connection to the upright 11 and to the crosspiece 12, the section sections 23 each have a fold, enabling them to follow along a part of their length said upright 11 and said crossbar 12,

  To permit the subjection to it of any

  other scaffolding element, the scaffolding console so constituted comprises, at least at one point in its

  12, on the one hand, a tip 25, on which such an au-

  scaffolding element may, for its location, be engaged, and, secondly, transversely to said audit

  endpiece 25, for locking in position of said other element

  scaffolding, at least one piercing 26, suitable for the

  planting any means of support,% pins me

for example, through this one.

  In practice, such a nozzle 25 projecting from the crosspiece 12, on a first side thereof, in practice on its upper face, the bore 26 associated with this endpiece.

  25 affects an organ, detailed below, which also extends

  protruding from said cross-member 12, but from the other side

  tee of it, and therefore on the underside of this

crosses 12.

  In the embodiment shown in FIGS.

  1 to 6, two end pieces 25, each respectively disposed at the ends of the crosspiece 12, are provided on the side of said crosspiece 12 opposite the upright 11, said crosspiece 12 thus carrying a tip 25 at each of its ends, and the present at the end corresponding to the amount l is established in the extension of said amount 11, drilling 26

  partner then directly affecting that amount 11.

  Thus, with regard to this nozzle 25, the body comprising the piercing 26 associated with it is constituted directly

by the amount He himself.

  By cons, with respect to the tip 25 disposed at the other end of the crosspiece 12, the member comprising the associated bore 26 is constituted by a specific section of tube 27 attached for this purpose, for example by welding, on the

underside of the cross member 12.

  In practice, the profile section 23 of the corresponding triangulation means 13 extends to this section of tube 27, being properly secured to it,

for example by welding.

  In a manner known per se, each endpiece 25 is constituted

  killed by a section of tube that has undergone longitudinal shrinkage on each of its faces, in the median zone thereof, and thereby having a transverse contour

  starry, as best seen in Figure 3.

  Anyway, the distance D1 between the base of a tip 25, appreciated at its connection to the cross member 12, on the one hand, and the axis of the hole 26 associated therewith,

  on the other hand, is made at most equal, and in practice

  at the distance D2 separating the base of the sleeve 18 which forms the upright 11 from its foot, on the one hand,

  and the axis of the bore 20 associated with this sleeve 18, on the other hand.

  Any of the tips 25 of the next console

  the invention may, for example, make it possible to subjugate

  ci, as schematized in broken lines in FIG.

  another scaffolding console 10 'of similar construction

  corn. It suffices, in fact, to do this, to engage by its foot the upright 11 of this other scaffolding bracket 10 'on the endpiece 25 concerned, until engagement thereon of the sleeve 18 formed by its lower end such

amount 11, figure 6.

  Assuming, as shown, that the tip 25 concerned is the one disposed at the end of the crosspiece 12 opposite the amount 11 of the console 10, such a commitment leads

  the flanges 19 of the console 10 'to cover, each res-

  respectively, the corresponding flanks of the tube section 27 of said bracket 10. It suffices then, the holes 20, 26 corresponding being aligned, as shown in Figure 6, to engage in these holes 20, 26 any means of maintenance ,

  a pin for example, not shown.

  Of course, such a second scaffolding console

  may also be implanted, following the same conditions

  than the above, on the end-piece 25 arranged in the

  11 of the console 10.

  In all cases, and according to arrangements known by themselves, it allows the staged constitution of a

  scaffolding along a blanket, if desired.

  On one or the other of the end pieces 25 of the console of

  The scaffolding 10 according to the invention may also be engaged

  according to the same conditions as above, a rod or candelabrum 30, provided that, in the manner of the amount 11 of such a scaffolding bracket 10, this railing rod 30 forms, at its lower end,

  or foot, a sleeve 18 extended by flanges 19 to pierce

  20, as schematized in broken lines in Figure 1. In this Figure 1, it has been assumed that the rod of

  railing 30 was to be located on the endpiece 25 provided

  se in the extension of the amount 11, but it goes without saying that it can just as easily be located on the tip 25

  disposed at the other end of the cross member 12.

  Following provisions comparable to the previous ones,

  the scaffolding console 10 according to the invention may also

  be subject to any other element of

  scoring comprising a tip 25 and a hole 26 associated with

this one.

  This is the case, for example, as schematized in dashed lines in Figure 1, for the attachment of such a scaffolding console 10 to any support arm 32 adapted to allow support on the one of the walls of the

construction to be treated.

  Known in itself, and not part of the pre-

  In this invention, such a support arm 32 will not be described in detail here. It will suffice to indicate that, including a crossbar 33,

  he presents, according to the invention, in projection on this work.

  poured 33, a first side thereof, a nozzle 25, and also projecting on the crosspiece 33, but on the other side thereof, anorgan 27, a simple tube section for example, having the bore 26 associated with said tip 25.

  In the variant embodiment represented on the

  7, the cross member 12 of the scaffolding console 10 is

  the invention comprises, on the lower surface of its crosspiece 12, at the end thereof opposite its amount

  11, a shoe 35 presenting itself, recessed on its surface.

  this lower, a recess elongated transversely in form

  vault 36, for the eventual hanging of the assembly on any support bar 37, as schematized

  in broken lines in this figure 7.

  In practice, in addition to the cross-member 12, the shoe 35 is

  joined, for example by welding, on the one hand, on the

  of the tube constituting the proximate member 27, and, on the other hand,

  corresponding section section 23 of the means of trian-

regulation 13.

  In the embodiment variant represented on the

  Figures 8 to 10, it is on such a shoe 35 that is found-

  m6 the bore 26 associated with the tip 25 overlying.

  This is, in this case, a shoe made by molding, said shoe having a core 39, with, at the edge of its upper edge as well as the edge of its recess

  in the form of a vault 36 and the hole 26, a rim 40 extends

  on both sides of this soul 39,

specifically to this one.

  For drilling 26, this flange 40 has, perpendicularly

  said soul 39, an extension larger than for the tran-

  top of it and that for the shaped recess

of vault 36.

  According to a development of the invention, drilling 26

  a, in cross-section, an ovoid contour, with its por-

  the tapered direction directed away from the associated tip 25. So, set up at the top of this piercing

  26, in its largest passage section, as schemati-

  in dashed lines 421 in FIGS. 8, 9, the goupil-

  the implementation then moves downwards, di-

  rection of the tapered portion of said bore 26, under the ef-

  of the charge applied to it by the element

  it ensures the maintenance; as shown schematically in

  42II in FIGS. 8, 9, it then becomes jammed in said tapered portion of the bore 26, which advantageously limits the transverse clearance of which can be

  the object concerned, or even mime eliminates any possibility of

playability for this one.

  Furthermore, in the embodiment shown, it is associated with the arch-shaped recess 36 of the shoe 35, as shown schematically in broken lines in FIGS.

  and 10, a fastener 44, which, in outline in overall elevation,

  hemi-circular, and pivotally mounted on said hoof

  thanks to a piercing 45 of it, is able to

  click on the support bar 37 on which said shoe 35 is engaged by said vault-shaped recess 36, for locking the assembly on this bar of

support 37.

  For such an unlocking, the fastener k4 extends from

  more than 1300 and is elastically deformable.

  Of course, the present invention is not limited to the embodiments described and shown, but

  encompasses any variant of execution.

  In particular, several holes 26, for example

  staggered, can be associated with the same endpiece 25.
