  The present invention generally relates scaffolding floors to be established longitudinally between two spacers connecting themselves two consoles or

  other scaffolding support members.

  Usually, the decking constituting such a floor

  scaffolding consists of planks which, arranged in parallel

  to each other, overlap with others

  planks similar to their extremities, to the right of

  the or other scaffolding support members concerned.

  The protrusion thus formed by the overlapping ends

  These boards make it difficult for people to

  As a result, it is necessary either to have boards whose length corresponds exactly to the spacing between the brackets or other scaffolding support members to be connected, or to cut exactly to such a spacing between them.

boards used.

  In the first case, an im-

  carrying, inevitably expensive and cumbersome, boards of different lengths, and in the second case, there is inevitably, at each establishment of a floor, significant falls, gradually decreasing in length

the boards available.

  The present invention generally has the

  purpose of a clean jointing joint to minimize,

  re even cancel, these disadvantages.

  This jointing crossbar, which is intended for scaffolding floors to be established longitudinally between two spacers connecting themselves two consoles or others

  scaffolding support members, is, in general,

  the, characterized in that it comprises, in combination, a sole adapted to be secured to said spacers,

2503,775

  from one of these spacers to the other, and a plate, adapted to be removably attached to said sole, to

  the way of a lid, to enclose the decking cons-

the floor to be established.

  Such a jointing crossbar may advantageously be established at any point of the spacers connecting two consoles or other scaffolding support members,

  so that it is no longer necessary for the connection

  consoles or other scaffolding support members.

  In addition, it is no longer necessary for the successive boards of such a scaffolding floor to join end to end, within the limits of the clearance allowed by the width of the jointing crosspiece according to the invention, and more precisely, the game allowed by the half-width of this cross, which economically avoids a recovery

  scaffolding floor between two scaffolding consoles;

  FIG. 4 is, on a larger scale, a sectional view of

  transverse pe of this jointing cross, following

line IV-IV of FIG.

  As illustrated in these figures, and more particularly in FIG. 3, it is necessary to establish longitudinally, between two scaffold support members 10, a floor

Scaffolding 11.

  In the example of implementation represented, the or-

  The scaffold support gantries 10 are consoles for

  in a manner known per se, to be suspended

due to the construction to be treated.

  But, alternatively, it could equally well be

  Scaffolding ganes taking direct support on the ground.

  Anyway, and in a manner known per se, these scaffolding support members 10 are interconnected by a cradle 12 formed of two telescopic struts 13, which at their ends are provided with clean hooks 14 to allow them to be engaged on the scaffold support members 10, and which, in their middle part,

  are connected to each other by a cross member 15.

  Such a cradle 12 not forming part of the present invention, and being well known by itself, it will not be

described in more detail here.

  The scaffolding floor 11 is to be established longitudinally

  between the spacers 13 of this cradle 12.

  It is formed for this purpose of a board decking

parallel 16.

  According to the invention, it is used, from place to place, for the end-to-end connection of such boards

  16, a grouting crosspiece 18.

  Such a jointing cross 18, which is

  2, comprises, in combination, a sole 19, adapted to 4tre subject to the spacers 13, a cradle 12, one of these spacers 153 to the other, and a plate 20, to be 8tre removably attached to said sole 19, in the manner of a cover, for

  enclose the decking constituting the floor 11 to establish.

  For its subjection to the spacers 13 of the ber-

  12, the sole 19, in the embodiment shown in FIG.

  at each of its ends, projecting from its lower face, two parallel cheeks 22, 23, by which it is adapted to be engaged, in the manner

  of a rider, on such a spacer 13.

  In practice, in the embodiment shown, the cheek 22, which at the end of the sole 19 is the outermost, is formed by a simple folding in.

square of this sole 19.

  In parallel, the associated cheek 23 is, for example,

  and as represented, a simple dish, suitably

  worn on the sole 19, for example by welding, parallel

  to the corresponding cheek 22.

  Preferably, and as shown, the cheeks 22, 23 each correspond in correspondence with a passage 24, 25,

  for mine in place of a pin 27.

  As shown, it may be a pin to

pivoting locking pawl.

  But it can also be a pin whose

  maintenance is provided by a locking pin.

  Such pins being well known in themselves, and not part of the present invention, they do not

  In the embodiment shown, the sole

  19 has, at each of its ends, trans-

  horizontally projecting on its upper surface, a

  end stop 29, suitable for counterbearing the platform laterally.

  the constituent floor of the floor 11 to be established.

  In practice, such a stop strip extends slightly

  away from the corresponding end of the semi-

  19, parallel to such an end.

  In addition, in the embodiment shown, the

  sole 19 still has, from one end to the other

  longitudinally projecting on its upper surface, in the median zone thereof, a stub sill 30, able to counter-end the decking constituting the

floor 11 to be established.

2503,775

  This stub sill 30, which in practice in

  the exemplary embodiment shown, extends from one of the

  The stop lugs 29 at the other, level with these stop bars 29, may, for example, and as shown, be constituted by a simple flat. But, alternatively, it can also be a profile

  tubular with rectangular section, square or other.

  In the embodiment shown, the plateau

  has a width less than that of the sole 19.

  It goes without saying, however, that, alternatively, it can

  have a width equal to that of the sole 19, or greater than

than this one.

  In any case, preferably, and as

  felt, it carries, from place to place, projecting on its sur-

  underside, spikes 32, suitable for its anchoring in

  the decking constituting the floor 11 to establish.

  To * be attached to the sole 19, the plate 20 has, at each of its ends, a passage 33, of

  buttonhole length to allow for tolerance

  rance, and the soleplate 19 comprises, in the form of

  correspondance, a threaded bush 34, in cooperation with, for each end, a fastening key 35, intended to be engaged in screwing in the threaded bush 34 of the sole 19 after passing through the corresponding passage 33 of the

tray 20.

  In the embodiment shown, the threaded bushings 34, which are each attached, for example by welding, to the outer side of the stop strips 29, are each constituted, in the exemplary embodiment

  shown, a ring 36 surmounted by a nut 37.

  Together with each fastening key 35, a lock washer 38 of size

  greater than the smallest dimension of the crossing 33 corres-

  laying of the plate 20, and such a lock washer 38 can be permanently attached to such a fixing key 35. For its implementation, the jointing crossbar thus formed is simply engaged by the cheeks 22,

2503,775

  23 of its sole 19 on the spacers 13 of the cradle 12

  concerned, at any point in it.

  Pins 27 are then put in place on these cheeks 22, 23, for securing the sole 19 to the struts 13. Of such a cross-joint 18 to another,

  or such a cross-jointing joint to a support member

  scaffolding port 10, are then longitudinally

  blies, parallel to each other, the boards 16

  specific to the construction of the scaffolding floor 11

  sought. Such boards do not necessarily come in

  bearing against the abutment sill 30 of the sole 19.

  On the contrary, within the limits of the half-width of this sole 19, and given a sufficient margin of safety, a certain clearance may exist longitudinally between such a stop abutment 30 and one or other of the boards 16 implemented, so that the length

  of these do not necessarily have to be adjusted in

sequence.

  The plate 20 is then attached to the lanches 16 and put in place, with anchoring of its tips 32 therein, and, using the fixing keys 35, it is

  then removably secured to the sole 19 to the.

which he is associated.

  As will be noted, in the example of implementation

  4 shown in FIG. 4, the boards 16 used have a height greater than that of the strips and

  stub sill 29, 30 of the sole 19.

  But, it is not necessarily so.

  Given the length of the spikes 32 of the plateau

  , the thickness of the boards 16 can indeed be equal

  within certain limits, less than that of

  and stub sill 29, 30 of the sole 19.

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

  encompasses any variant of execution.
