Definitions

  • the present invention relates to a joint for installation of scaffolding tubes, and a scaffold comprising such a joint.
  • the present invention preferably, although not exclusively, takes its place in the building field, where scaffolds are used for construction and/or renovation of buildings.
  • Application of the present invention also occurs, for example, in the manufacture of lattice structures adapted to temporarily support terraces, stands, covering elements and the like.
  • Scaffolds are formed with a plurality of tubes connected to each other by joints.
  • the known art joints generally comprise two sleeves fastened to each other, in which each sleeve retains a respective tube.
  • each sleeve In order to removably tighten the joints on the tubes each sleeve is divided into two halves that are made integral with each other by bolts and nuts.
  • the two halves are tightened or clamped on the tube, retaining it in place.
  • the technical task underlying the present invention is to propose a joint for installation of scaffolding tubes and a scaffold comprising such a joint, adapted to overcome the above mentioned drawbacks of the known art.
  • a joint for installation of scaffolding tubes in accordance with the present invention has been generally denoted by numeral 1.
  • Joint 1 comprises a first body 2 divided into a first half 3 and a second half 4 for engagement of a first scaffolding tube 100.
  • Joint 1 further comprises a second body 5 also divided into a first half 6 and a second half 7 for engagement of a second scaffolding tube 101.
  • the first halves 3, 6 of the two bodies 2,5 are secured to each other.
  • the two first halves 3, 6 of the two bodies 2, 5 are of one piece construction, i.e. they are made of a unitary piece. In addition they are coupled to each other in such a manner that the engaged scaffolding tubes are oriented to each other so as to substantially form a right angle.
  • the two first halves 3, 6 of the two bodies 2, 3 can be physically distinct parts joined by a hinge or other device adapted to enable mutual rotation of the two halves 3, 6.
  • scaffolding tubes concerned with the two bodies 2, 5 can be such oriented to each other as to form any type of angle.
  • the two halves of each body comprise a respective inner surface (shown in Fig. 4 is the inner surface of the first half 3 of the first body 2), i.e. the surface designed to come into direct contact with the scaffolding tube, which is of semicylindrical shape, so that said halves substantially match the shape of the tube (usually of cylindrical shape).
  • Clamping means 8 is present between the first halves 3, 6 and the second halves 4, 7 of each body 2, 5.
  • the clamping means 8 function is to make the second halves approach the first halves thus encircling a respective scaffolding tube, in such a manner that the two scaffolding tubes are retained by the two bodies 2, 5.
  • the clamping means 8 comprises at least two substantially wedge-shaped bodies 9, 10 which are slidable relative to the second halves 4, 7 inside respective slots 11, 12 (the latter being clearly shown in Fig. 3 ).
  • Each wedge-shaped body 9, 10 is active on the second half 4, 7 of the respective body 2, 5 for achieving a plurality of approached positions between the second half 4, 7 and the first half 3, 6, depending on the penetration degree of the wedge-shaped body 9, 10 into slot 11, 12.
  • the wedge-shaped body 9 of the first body 2 is slidable within slot 11 of the first body and, depending on its relative position within slot 11, exerts a more or less intense force on the second half 4 moving it close to the first half 3 to a greater or lesser degree.
  • the wedge-shaped body 9 comes into contact with the second half 4 when it slides inside slot 11.
  • each wedge-shaped body 9, 10 comes into contact with a tailpiece 13, 14 secured to, and jutting out of the respective second half.
  • each slot 11, 12 and each wedge-shaped body 9, 10 is movable relative to the respective second half 4, 7 (see Figs. 3 and 4 ) so as to obtain at least two distinct insertion directions of the wedge-shaped body 9, 10 relative to the respective second half 4, 7 ( Fig. 1 shows an insertion direction of the wedge-shaped bodies relative to the respective second halves and Fig. 2 shows an opposite insertion direction).
  • each wedge-shaped body 9, 10 sliding within the respective slot 11, 12 and the slot 11, 12 itself are movable relative to the respective second half in such a manner that the insertion direction of the wedge-shaped body into the slot relative to the second half (i.e. the penetration direction of the wedge-shaped body into the slot) can take at least two different positions (for instance, either from the right to the left as shown in Fig. 2 or from the left to the right, as shown in Fig. 1 ).
  • Joint 1 further comprises two pins 15, 16 each of which is provided with a slot 11, 12.
  • Each pin 15, 16 is inserted in a hole formed in the first half 3, 6 and is provided with a limit element 17 in such a manner that it cannot thoroughly pass through the hole.
  • the limit element 17 has greater sizes than the hole.
  • the limit element 17 is obtained through thickening of the pin 15, 16 section having a rounded shape so as to facilitate rotation of the pin 15, 16 relative to the hole formed in the respective half 3, 6.
  • the limit element 17 is of one piece construction with the pin 15, 16.
  • Each pin 15, 16 comprises a first distal end 18, 19 relative to the hole present in the first half 3, 6 in which slot 11, 12 is formed.
  • the first end 18, 19 is insertable in the tailpiece 13, 14 and at least partly emerges therefrom (see Figs. 1 and 2 ).
  • the tailpiece 13, 14 has a fork-shaped configuration to enable introduction and removal of pin 15, 16 thereinto and therefrom respectively.
  • the second end of pin 15, 16, i.e. the end opposite to the first one 18, 19, carries the limit element 17.
  • each wedge-shaped body 9, 10 comprises a first portion 20, 21 having greater sizes than the sizes of the corresponding slot 11, 12, in such a manner that this portion of the wedge-shaped body cannot fully pass through the slot.
  • each wedge-shaped body 9, 10 comprises a second portion 22, 23 that is substantially opposite to the first one 20, 21 and has smaller sizes than the slot. Acting on the second portion 22, 23 is a limit stop 24, 25 interfering with slot 11, 12 in such a manner that also the second portion 22, 23 cannot fully pass through slot 11. 12. In this way, the wedge-shaped body 9, 10 cannot be removed from its engagement with slot 11, 12.
  • the limit stop 24, 25 is a rivet inserted in a hole formed in the second portion 22, 23 of the wedge-shaped body 9, 10 which is submitted to plastic deformation in such a manner that it cannot be removed from the hole.
  • the clamping means 8 further comprises two connections 26, 27 each of which extends between the respective first 3, 6 and second 4, 7 half of each body.
  • the two connections 26, 27 are disposed on opposite sides on the first and second halves relative to pins 15, 16 provided with slot 11, 12, so as to fasten the first halves 3, 6 and second halves 4, 7 to each other.
  • connection 26, 27 is inserted in eyes 28, 29 of the first and second halves, in particular the connection being able to slide and rotate within each eye 28, 29.
  • the two halves of the body are secured to each other while they can at all events be mutually moved or shifted to enable easy installation of the joint on the scaffolding tube.
  • each connection 26, 27 comprises two limit stops 30, 31 placed on opposite ends of the connection itself to prevent it from slipping off the eyes 28, 29.
  • the limit stops 30, 31 are of one piece construction with the connections and consist of thickened portions of the connection sections, obtained by moulding or plastic deformation of the connection end.
  • joint 1 does not include any element that can be dismantled and installed again, such as bolts or nuts. In this way, it is practically impossible to only replace some components of the joint. Therefore, the structural integrity of the joint when in use is ensured, since a fault (due to wear, for example) of a single component of the joint cannot be remedied in a manner independent of the remaining part of the joint. In other words, in case of decay of the mechanical properties of a component of the joint making it useless, replacement of the whole joint is required.
