Definitions

  • the present invention relates to the safety of personnel at height on shoring towers (10) used in the building construction industry.
  • the users who check the good conformity of the finished height of the prefabricated element supported by "DOKA" beams (15), realize too late that the cylinders (9) for supporting the forks (16) of the beams (14) to be keyed are too unscrewed and far exceed the recommended working height of 1.50 m from the last plate (17) of the shoring tower.
  • they should then completely tighten the jacks (9) fork (16) and feet and insert an additional element of tower frame by adding a plate (17) complete to be up to keying of the beam (14).
  • they climb like acrobats and therefore without security on the last bars of the shoring tower to get to the height of keying beams (14) but are no longer protected by any guard rail.
  • the device according to the invention makes it possible to remedy this problem of safety of risk of falling in height of the shoring towers.
  • This system is called "CHANDELIER Z”.
  • the "CHANDELIER Z” is intended for shoring towers (10) used in the building construction industry, for the safety of personnel working at height. It comprises a plate (2) assembling a first tube (1) with a second tube (3), and a third tube (4) sliding in the second tube (3) having a fork (5) at its head and a bore in the base (8) provided for a pin.
  • the first tube (1) is introduced around the jack (9) fork (16) of the shoring tower (10).
  • the movable tube (4) supports a standard post (13) guardrail (11).
  • a device of four "CHANDELIERS Z” must be systematically installed at the corners of the shoring tower (10) during its assembly, by inserting them at the same time as the jacks (9) and their fork (16).
  • This device uses posts (13) and guard rails (11) adaptable to the standard shoring towers (10). Indeed, when staff are no longer up to regulatory safety work, they must at first place a belt of four smooth (11) in the forks of the "CHANDELIERS Z", then mount posts (13) stuck in the "CHANDELIERS Z" while remaining on the last floor (17) already secure. In a second step, they can remount a complementary floor stage (17) without adding additional tower frame provided to ensure their safety by an additional installation of the sufficient number of standard guard (11) corresponding to 1.00 m of regulatory protection.
  • This belt of guards (11) fixed on the "CHANDELIERS Z" at the top of the tower (10) is not always useful but has the merit of proposing to the personnel, if they feel the utility, a quick and efficient solution allowing them to work at ideal height and in safety.
  • the "CHANDELIER Z” pivots around the axis of the cylinder (9) of the tower and allows a great flexibility of installation and many positions of the posts (13) and the guard (11), without hindrance on the assembly of the "DOKA” beams (15), giving staff a more secure work environment.
  • Each "CHANDELIER Z” is identifiable by its red color for perfect visibility by far by the team leader and the crane operator.
  • the "CHANDELIER Z” is characterized in that the plate (2) comprises a specific trapezium cut, allowing the mounting of the posts (13) with a difference in height between the two positions which is 0.20 m (the height of a beam "DOKA") but while leaving the axes of the first tube (1) parallel with the second tube (3).
  • the shape of the plate (2) also allows complete blocking of the rails (11) with the help of the fork (5).
  • the "CHANDELIER Z" is characterized in that a curved fork (5) is welded to the head of the third tube (4) allowing the locking of railing rails (11).
  • the device is characterized in that the fork (5) has a length sufficient to block two smooth (11) guard perpendicular connection.
  • the "CHANDELIER Z" makes the dimension of the plate (2) in length is greater than the size of the rotational movement of the fin (12) so that the second tube (3) receiving the post (13) is enough eccentric with respect to the first tube (1) inserted in the cylinder (9).
  • the "CHANDELIER Z” allows a height adjustment potential of the first smooth. Indeed, according to whether the "CHANDELIER Z" is engaged in one direction or the other of the jack (9), a difference between these two positions of 0.20 m will make it possible to prevent the rails fixed on the posts (13). ) do not abut the fin (12) or "DOKA” beams (15) supporting the key beam (14).
  • the "CHANDELIER Z" is characterized in that the inner diameter of the second tube (3) is defined for a sliding fit according to the outer diameter of the tube (4).
  • the second tube (3) allowing the establishment of a third tube (4) sliding to receive a guard post (13).
  • the "CHANDELIER Z" is characterized in that the third tube (4) has a defined inside diameter for a tight fit according to the outside diameter of a standard post (13). The shoulder of the post coming to lock on the fork (5) of the third tube (4).
  • “CHANDELIER Z” is a device that features a first female tube 0.15 m high (1), an inner diameter slightly greater than the diameter of the male jack (9) of the shoring tower to be able to slide around.
  • This first tube is vertically welded to one end of a metal plate (2) perforated by an eyelet (6), for off-centering on the other end a second female tube (3) 0.10 m high.
  • This is a casing of two tubes: the first welded parallel to the plate (3) and the second (4) slides inside the first.
  • the inner diameter of the tube (4) corresponding to the outside diameter to that of a standard post (13) male guardrail.
  • This tube (4) is provided with a fork (5) smooth blocking curve (11) and a pin allowing the reversibility of the "CHANDELIER Z".
  • the slide height clearance corresponds to slightly more than the sum of two smooth diameters.
  • the "CHANDELIER Z" is characterized in that it comprises a bore (8) disposed right at the bottom of the third tube (4) provided with a pin preventing the second tube (3) from being separated from the third tube (4) and also allowing the security of the reversibility of the system.
  • the first tube (1) and the second tube (3) are eccentric 0.19 m to not impede the rotation of the fin (12) of the cylinder (9) of 0.16 m radius of action.
  • the "CHANDELIER Z" is characterized in that the bore (6) is 0.02 m in diameter in the plate (2) allowing the attachment by a standard rudder hook for the purpose of hoisting them easily upwards. shoring towers (10) and condition them quickly for transport.
  • the height of the support tube of the post (3) is standardized for reasons of tear resistance and torsion.
  • the "CHANDELIER Z” is characterized in that the first tube (1) which engages in the jack (9) has at its two ends, two flanges (7) of outside diameter greater than the diameter of the jack (9), for thus allow a total recovery of the loads, these soles (7) being welded to the first tube (1) to make the assembly integral. These two circular steel soles (7) allow the recovery of load forces to allow adaptation to all types of shoring towers.
  • a change in the height of the tube engaging around the cylinder can be revised slightly downward to save space with only limit the study of resistance to tearing and torsion.
  • the height of the support tube of the post is constant for the same reasons of resistance pulling and torsion.
  • the site team found its robustness by weighing with levers and was enthusiastic from the test phase. Approval as a safety accessory is required.
