Definitions

  • the present invention relates to a rack or cable site lift, that is to say a lift or elevator, of the type comprising a mast of polygonal section, generally rectangular or square, composed of assemblable elements and intended to be moored against the exterior face of a construction as it rises and two angles of the same face of which constitute the raceways of a cabin in which personnel and / or equipment can take place, means such as that rack or cable being provided to allow the cabin to be moved along the aforementioned face of the mast and to be stopped at any desired level.
  • a rack or cable site lift that is to say a lift or elevator, of the type comprising a mast of polygonal section, generally rectangular or square, composed of assemblable elements and intended to be moored against the exterior face of a construction as it rises and two angles of the same face of which constitute the raceways of a cabin in which personnel and / or equipment can take place, means such as that rack or cable being provided to allow the cabin to be moved along the aforementioned face of the mast and to
  • each element of the mast forms a one-piece assembly consisting of tubular parts assembled by welding and of which at least two angles are constituted by tubes of square section or rectangular, free on at least three of their faces, each of which receives at least one support or guide roller, carried by the cabin.
  • each element ends in a cross section perpendicular to its longitudinal axis and that, consequently, all the joints between successive elements are contained in planes orthogonal to this longitudinal axis, which does not contribute to a good flexural strength of the mast.
  • the assembly of the sheet metal panels is of the removable type and each panel corresponds substantially to a section of one of the lateral faces of the mast and whose longitudinal edges are folded and pierced with rows of holes for rapid assembly and disassembly at sheet metal panels of the adjacent faces, the panels of the same face of the mast being offset longitudinally with respect to the panels of the other faces of this mast, so that each joint between two panels of one face is at a level different from the joints of the panels on the other sides.
  • this mast by sheets, each of which corresponds only to one of its faces allows, by a judicious offset of the sheets of two adjacent faces, to offset their respective joint planes and, consequently, avoid the mast having transverse joint planes weakening its stiffness.
  • each sheet metal panel constituting a section of one of the faces of the mast has longitudinal edges bent at 90 ° and the raceways for the rollers of the cabin are constituted by folded sheet metal profiles having two longitudinal assembly wings folded at 90 ° relative to each other and rows of holes having the same distribution as those of the sheet metal panels of the lateral faces of the mast, so as to allow their assembly using the same bolts.
  • the sheet metal panels of the four faces of the mast are identical, which facilitates the storage and mounting of these panels.
  • the raceways for the rollers of the cabin consist of longitudinal ribs obtained by bends and counter-bends made between the central core and the assembly wings folded 90 ° sheet metal panels corresponding to the face of the mast along which the cabin moves.
  • the sheet metal panels making up the mast have transverse ribs allowing their stiffening and bosses allowing the fixing of a rack.
  • each sheet metal panel has an angled-shaped stamp allowing it to be clamped simultaneously with the corresponding edges of the adjacent panel, using flanges having a profile complementary to that of the two stampings placed at the end. at the end.
  • the bolt through holes in the sheet metal panels as well as in the wings of the profiles possibly forming raceways are formed in frustoconical bowls capable of fitting together 'one in the other.
  • recesses are provided which can occupy each part of the panel in non-ribbed sheet metal.
  • the presence of these recesses has in Q utre, the advantage of reducing the wind resistance.
  • each raceway a single track of trapezoidal cross section intended to receive rollers of complementary section capable of ensuring, simultaneously, the support, the retention and the guiding of the cabin.
  • this site lift is of the type comprising a mast (2) of square section moored against the outside face (3a) of a building (3) under construction as the ferret rises of this building.
  • Two angles (4) and (5) of the mast (2) adjacent to the same lateral face of this mast are arranged to present raceways for the rollers not visible in FIG. 1, of a cabin (6) intended to be moved along the aforementioned face of the mast (2) and along the face (3a) of the building (3).
  • the driving of the cabin (6) along the mast (2) is ensured by the engagement of a driving pinion (7) carried by the cabin (6), in a rack (8) carried by the aforementioned face of the mast (2).
  • a bracket (9) carried by the roof of the cabin (6) makes it possible to increase the height of the mast (2) as and when required during the construction of the building (3).
  • the mast (2) of this elevator consists of the assembly of sheet metal panels (11) each of which corresponds substantially to a section of one of its lateral faces and whose longitudinal edges are folded over 90 ° to form assembly wings, respectively (11 a) and (11 b), with sparingly series of holes (12) and (13), on either side of the fold line for the passage of assembly bolts (14).
  • this mast (2) using sheet metal panels (11) makes it possible to offset the panels on the same side with respect to the panels on all the other sides of the mast (2) and thus obtain, at no level, the mast (2) does not have a transverse joint plane which would weaken its holding.
  • the raceways (4) and (5) are formed by folded sheet sections having two longitudinal assembly wings (4a , 4b) and (5a, 5b), bent at 90 ° to each other and each of which has a series of holes (15) and (16) intended to be placed in coincidence with the rows of holes, respectively (12) and (13), located on either side of a fold line of a longitudinal edge of a panel (11), to allow the assembly of this raceway (4) or ( 5) to the mast (2) using the same bolts (14) used to assemble the adjacent sheet metal panels (11).
  • each raceway (4) or (5) has three tracks, namely two tracks (17) and (18) parallel to each other and parallel to the plane of the face of the mast (2) along which moves the cabin (6) and a third track (19) perpendicular to the previous two.
  • Each track (17) is intended to receive the support rollers (21) of the cabin (6)
  • each track (18) is intended to receive the retaining rollers (22) of the cabin
  • each track (19) is intended to receive the lateral guide rollers (23) of the cabin.
  • FIG 4 which shows a detail of the assembly of a raceway (4), illustrates a particular and interesting characteristic of this assembly, characteristic according to which each hole (12, 13, 15, 16), formed in the panels (11) and the raceways (4) or (5), is formed in a frustoconical bowl interlocking with each other and participating in the holding of the mast, so as to reduce, if not completely eliminate, the shear forces to which the assembly bolts (14) are subjected.
  • each panel (11) has along its upper and lower edges, a stamped (24) in the form of an angle, allowing its attachment to the edges facing it of the panel located above or below it, using flanges (25) composed of male (25a) and female (25b) elements joined to each other by screws (26) and having a profile complementary to that of two stampings (24) placed end to end of the two elements (11) considered.
  • FIGS. 6 and 7 illustrate an alternative embodiment of this mast (2) according to which the face of the mast (2), along which the cabin (6) moves, is composed of sheet metal panels (27), each, between its central core constituting the aforementioned face and each of its longitudinal assembly edges (27a) and (27b), has a raceway, respectively (4) and (5) identical to the raceways (4) and (5) of the example illustrated by FIGS. 2 to 4.
  • This arrangement reduces the number of parts to be assembled in the corresponding angles of the mast (2), but requires that the panels (27) constituting the face considered of the mast (2 ) are different from the panels (11) constituting its three other faces.
  • the holes for the passage of the assembly bolts (14) are advantageously located in frustoconical bowls, as illustrated in FIG. 7 in order, as in the previous example, to relieve the bolts (14) shear forces.
  • FIG. 8 shows an alternative embodiment of the raceways (4) and (5) according to which the track (19) of each raceway (4) and (5) is shaped so as to have a trapezoidal section, at instead of being flat, so that the support rollers (21) and retaining (22) and the tracks (17) and (18) corresponding thereto, can be deleted.
  • the panels (11) and possibly (27), forming part of the mast (2) are advantageously perforated by windows, respectively (28) and (29) having the effect, not only to lighten them, but also to reduce their wind resistance.
  • each of them has one or more bosses (31) allowing the fixing of the rack (8) without it being necessary to provide spacers forming spacers, as well as stiffening ribs (32).
