Definitions

  • the present invention relates to tubular type scaffolding, a method of mounting them and the horizontal crosspieces of these scaffolds.
  • the technical sector of the invention is that of the construction of scaffolds of tubular type for rapid assembly and disassembly.
  • Scaffolding of the tubular type is called scaffolding composed of vertical elements connected to one another by horizontal crosspieces or spacers and possibly by oblique bracing.
  • the vertical elements, the crosspieces and the braces are generally tubes, hence the common name of tubular scaffolding. It is specified that this designation is not limiting and that the vertical, horizontal or oblique elements may be other than tubes, for example angles or beams in sections.
  • the vertical elements can also be constituted by a vertical wall, for example a metal tank wall or a ship's hull on which the horizontal crosspieces are fixed.
  • Tubular type scaffolds for rapid assembly and disassembly are well known and are very commonly used as work scaffolds in the construction of buildings, ships, tanks or to support formwork or to construct light structures easy to dismantle etc.
  • Tubular type scaffolds are known in which the vertical elements are fitted with attachment pieces fixed at determined levels and the horizontal crosspieces carry at least one of their ends an assembly piece which is rigidly assembled with a piece of attachment by a wedge-shaped key.
  • the FR patent. 1,521,232 (KWIKFORM Limited) describes such scaffolding in which the vertical elements comprise vertical bushings and the horizontal crosspieces are equipped at their two ends with an assembly part having two arms which engage on a bushing and which comprise slots in which a conical key is manually engaged.
  • U.S. Patent 3,817,641 (R.E. STEELE and AI) describes tubular scaffolds in which each horizontal cross member is fitted with a male end piece which fits into a socket carried by an upright. Each crosspiece carries a conical key which is engaged in two slots and which is placed manually and locked with a hammer.
  • tubular scaffolding comprising vertical elements which are equipped with horizontal collars carrying openings and horizontal elements which carry, at their ends, hooves which are provided with a horizontal slot which engages on a collar and two openings in which a conical key is manually engaged.
  • All known scaffolding of tubular type comprising a fork-shaped assembly part and a key which is pressed through slots in the fork has the disadvantage that a worker must access each assembly node in order to set up manually the key. This operation requires time and, moreover, it can be dangerous because during this operation, the horizontal cross member is only engaged on a socket without being connected to the latter and the scaffolding is not rigid.
  • a deformation of the scaffolding risks causing the fall of the cross member which can injure the worker or even drag him into his fall.
  • the primary objective of the present invention is to provide improved scaffolding so that the introduction of the key does not require a worker to access each connection point, but can be obtained automatically by a slight relative movement in the vertical direction of a cross after the forks located at the end thereof have been engaged around the bushes of the vertical elements.
  • Another object of the present invention is to provide scaffolding which comprises assembly sockets making it possible to fix a horizontal cross-member in an oblique direction relative to the vertical plane of symmetry of the sockets, which in particular makes it possible to lay non-perpendicular horizontal cross-members to a flat vertical support in the case where the sockets are fixed to such a support, for example to a tank wall or to a ship hull.
  • Another object of the invention is to provide scaffolding in which the sockets fixed to the vertical elements allow the fixing of oblique bracing.
  • Another objective is to provide scaffolding comprising keys which can be dismantled using cables or poles without requiring the effective presence of a worker responsible for locally hunting the keys.
  • a scaffold according to the invention is a scaffold of the tubular type which is composed of vertical elements fitted with hollow bushings and horizontal crosspieces comprising, at at least one of their two ends, a fork-shaped assembly part which comprises a vertical wall and two horizontal wings each comprising a slot, which fork carries a conical captive key which is engaged through the slot of the upper wing and which occupies a substantially horizontal rest position.
  • each key has a raised pivot which is located near the narrow end of the key and which comes to bear against the underside of said upper wing and said key and / or said fork further comprise means for positioning the key at rest so that the upper edge of said sleeve comes to bear slightly behind said pivot when said fork is engaged on one of said socket and pressed against the latter and means for guiding the descent by gravity of said key.
  • the method of mounting scaffolds according to the invention comprises the following operations.
  • the lateral faces of the bushings comprise at least one oblique bracing fixing hole.
  • this hole is extended by a lateral notch.
  • each key advantageously carries a hole or a slot making it possible to hang the key in order to lift it from a distance.
  • the invention results in new tubular type scaffolds for rapid assembly and disassembly.
  • An essential advantage of the scaffolding according to the invention lies in the fact that the keys for assembling the horizontal crosspieces on the vertical elements are put in place without any worker having to access the assembly nodes for a set up manual keys.
  • This implementation is obtained simply by a relative vertical movement of the crosspiece relative to the fixing sleeves.
  • the only weight of the sleepers is enough to tip the keys. Firstly, this results in a very significant saving in installation time.
  • accidents during erection of scaffolding are reduced.
  • it becomes possible to set up and remove horizontal crosspieces in places that are difficult to access by presenting them suspended on a cable or by guiding them with poles to engage the forks on the sockets.
  • the devices for positioning the keys at rest which cause the upper edge of the sockets to bear slightly behind the pivot of the key are essential for the proper functioning as well as the devices which guide the descent of the key by gravity.
  • This key blocking operation can be eliminated by vibrating the whole scaffolding, which is enough to block the keys.
  • the scaffolding according to the invention makes it possible to fix horizontal crosspieces in a console on a vertical wall.
  • the sockets thanks to the shape of the sockets, they make it possible to fix brackets perpendicular, oblique or parallel to the wall.
  • the scaffolding according to the invention makes it possible to fix oblique bracing directly on the sockets.
  • the vertical elements 1 carry attachment pieces 3, in the form of hollow sockets.
  • the sockets 3 are fixed to the vertical elements at determined levels.
  • the sockets 3 are constituted, for example, by a steel strip, which is curved and whose two ends are welded to the vertical element 1.
  • At least one of the ends of the horizontal crosspieces 2 is equipped with a part d 'hooking 4 which has the shape of a fork or a U-shaped bracket having two horizontal wings 4a, 4b connected together by a vertical wall 4c which is welded to one end of the cross member 2.
  • the opening of the fork 4 is greater than the height of the sockets 3, so that the fork can be engaged on a socket, the wings 4a and 4b then being placed above and below the socket 3.
  • the assembly between a fork 4 and a socket 3 is produced, in a known manner, by means of a wedge-shaped key 5.
  • the wings 4a and 4b each have a slot, respectively 6a and 6b and the key 5 is engaged vertically through the two slots 6a, 6b and through the hollow socket 3.
  • front or external faces or ends are called the faces or ends oriented towards the outside of the cross member 2.
  • the length of the slots 6a, 6b is determined as a function of the width and of the taper of the key 5 and as a function of the thickness of the sleeve 3, to allow the latter to be tightened when the key is forced downwards .
  • the key 5 has in the vicinity of its front end, that is to say of the narrowest end, a pivot 8 which is constituted for example by two projections 8a, 8b located on either side of the lateral faces of the key.
  • the pivot could be constituted by a single projection.
  • the slot 6a is a narrow slot whose width is barely greater than the thickness of the key 5 and less than the thickness of the projections 8a and 8b.
  • the slot 6b is a wide slot whose width is much greater than the thickness of the projections 8a and 8b which can therefore easily pass through the slot 6b.
  • the length of the slot 6b, in the direction parallel to the axis of the cross-member 2, is less than the greatest width of the key 5.
  • the key is held captive since the widest end of the key cannot pass through the slot 6b and only the projections 8a, 8b cannot pass through the slot 6a.
  • the protrusions 8a, 8b play a second function which is that of a pivot which comes to bear against the underside of the upper wing 4a when the upper edge of the sleeve 3 bears against the underside of the key at rest behind the pivot 8.
  • the push which is then exerted on the key causes the latter to rock around the pivot 8 and the key comes vertically and descends by gravity inside the sleeve 3 and the slot 6b.
  • This automatic tilting of the key is an essential characteristic of the scaffolding according to the invention. It allows faster assembly of scaffolding. It suffices to engage the two ends of a cross member 2 on two sockets 3, then to move the cross member slightly downwards so that the two keys are put in place and lock the cross member sufficiently to ensure good rigidity of the assemblies. .
  • the self-weight of the cross member is generally sufficient to cause the automatic tilting of the keys.
  • the assembly devices according to the invention make it possible to set up, and then to dismantle, as will be seen later, using lifting devices or poles, sleepers located in an inaccessible or dangerous position to reach. .
  • Figures 3 to 6 illustrate the various stages of the assembly operation of one end of a horizontal crosspiece 2 on a vertical element (ca) 1.
  • Figure 3 shows the first step during which the fork 4 is engaged around a bushing 3 fixed to the element 1.
  • the narrow end of the key carrying the pivot 8 is engaged against the underside of the wing 4a.
  • FIG. 4 represents the next step during which the cross-member 2 is moved downwards, so that the upper edge of the sleeve 3 comes to bear against the lower face of the key 5, behind the pivot 8, and tilt the key in the vertical position.
  • the fulcrum of the socket 3 against the key is very close to the pivot 8, so that it only takes a small vertical movement to tilt the key.
  • FIG. 5 represents the next step in which the key 5 is almost vertical and descends by gravity into the hollow socket 3.
  • Figure 5 shows the cases where the narrow end of the key 5 abuts against the outer end of the wing 4b which is bent upwards in front of the slot 6b, to form an oblique ramp against which the key slides. This ramp guides the key which engages in the slot 6b and which is positioned vertically as shown in FIG. 6.
  • the assembly parts of the devices according to the invention include means for ensuring correct positioning of the key 5 at rest.
  • a first means is a shoulder 10 visible in the figure which comes to rest at rest against the vertical wall 4c of the fork 4 and which forms a stop preventing the key from moving back, so that the pivot 8 is placed in front of the vertical wall of the socket 3.
  • the upper wing 4a of the fork 4 has a fold 11 at right angles downward, which forms a stop against which abuts the front end of the key at rest.
  • This front stop 11 and the rear stop 10 give the key 5 a well-defined rest position and such that the fulcrum of the upper edge of the sleeve 3 against the key is behind the pivot 8 and at a short distance from that -this.
  • the fold 11 also contributes to guiding the key during its descent as seen in FIG. 5.
  • the fold 11 prevents the key from escaping from the fork 4 passing through the open end of the latter.
  • the key 5 may include a rectangular notch 12, the width of which is slightly greater than the thickness of the vertical wall 4c of the fork 4, which fits on the upper edge of this wall located at the rear end of the slot 6a.
  • the front and rear edges of the notch 12 fulfill the functions of front and rear positioning stop of the key 5 at rest and the folded edge 11 of the upper wing can be eliminated.
  • the rear stop 10 could be replaced by a lateral projection which would bear against the internal face of the vertical wall 4c of the fork 4.
  • Figure 12 shows another variant in which the cross member 2 carries a projection 21 against which abuts the rear end of the key in the rest position.
  • FIG. 5 shows that the ramp 13 comes to bear against the ramp 9 and slides along the latter to guide the key 5 towards the slot 6b.
  • FIG 7 is a top view of one end of a cross member 2 keyed to a socket 3 fixed to a vertical element 1.
  • the socket 3 has a U shape. It has a face 3a for supporting the key which is a flat vertical face perpendicular to the axis of the cross member 2 and two lateral faces 3b, 3c perpendicular to the bearing face 3a.
  • the socket 3 therefore has a vertical plane of symmetry PP '.
  • the lateral faces 3a, 3b are connected to the bearing face by curved junctions 3d, 3e having a radius of curvature R.
  • the cross member 2 is fixed in the position shown in Figure 7 where the axis of the cross member 2 is parallel to the plane PP '. This position ensures a particularly rigid assembly because the flat face 3a is kept pressed against the flat face 4c of the fork 4.
  • FIG. 8 shows that the crosspieces 2 can be fixed on the sockets 3 in an oblique direction relative to the plane of symmetry PP ', the key 5 then coming to bear against the curved internal face of a junction zone 3d, 3e.
  • Figure 13 is an enlarged view of a 3rd or 3d junction area having a radius of curvature R.
  • This figure shows the bearing edge of the key 5 which has a thickness E.
  • the key 5 can occupy angular positions covering a sector close to 90 °.
  • the width and the depth of the sockets 3 are sufficiently large relative to the length of the wings 4a and 4b so that they do not abut against the internal faces of the socket.
  • the crosspieces can be fixed perpendicular to the plane of symmetry PP 'by keying them against the side walls 3b and 3c .
  • FIGS. 9 and 10 show the fixing of an oblique bracing 14 on a node for assembling a horizontal crosspiece 2 with a vertical element 1.
  • the vertical element 1 is a tube which carries sets of four sockets 3 arranged in a cross.
  • the lateral faces of the sockets 3 each carry a hole 15 for fixing a bracing 14.
  • the bracing is fixed by means of locking rods 16 which carry at one end a lug 17.
  • the holes 15 have a lateral notch 15a visible in FIG. 9 which is used for the passage of the lug 17.
  • the rod 16 carries a bent handle 18 which makes it possible to rotate the rod to bring the lug 17 behind the internal wall of the sleeve 3.
  • the rod 16 carries a stopper 19.
  • rods 16 could be replaced by other equivalent fixing means.
  • FIGS 1 and 9 show that the keys 5 have in the vicinity of their widest end one or more holes 20 which serve to hang the key with a hook placed at the end of a cable or a lifting device for lift it out of its housing and uncouple the horizontal crosspiece from the vertical element.
  • the holes 20 can be replaced by equivalent means such as slots.
  • These attachment means 20 allow the keys to be lifted remotely, without any worker having to intervene locally.
