Definitions

  • the present invention relates to improvements made to the foldable gangways-supports for formwork formwork and it relates more particularly to the locking means allowing the gangway to be either folded for its handling or its storage, or unfolded in the position of use. , that is to say suspended from hooves secured to a wall.
  • Gangways of this kind which generally comprise a chassis serving as a platform and under which a hinged chair pivots.
  • the latter consists of at least two deformable triangles connected together by a longitudinal element allowing synchronization of movements.
  • Each deformable triangle has a bar which slides in a transverse beam of the chassis equipped with locking means, for example bolts or pinned pins. These locking means cooperate with co-axial bores made in the sliding bar and in the beam, so that the chair is immobilized in a folded or unfolded position.
  • locking means for example bolts or pinned pins.
  • the railings include at their base inclined rods of square or circular section, which slide in slides of the same section secured to the chassis.
  • Such a gangway has certain drawbacks with regard to the means for locking the articulated chair and the railing on the chassis.
  • the invention aims to provide automatic locking means no longer involving bolts or pinned pins, while remaining simple and easy to use.
  • the invention also aims to use the fact that the gangway is suspended from a crane during its handling to trigger, without the intervention of operators, either the opening and locking of the articulated chair in the position of use, or its folding and locking in the storage position.
  • Fig. 1 is a perspective view of the bridge according to the invention.
  • Fig. 2 is a side view showing the gangway in the unfolded position and suspended against a wall for its use.
  • Fig. 3 is a side view illustrating the gangway in the folded position of storage.
  • Fig. 4 is a perspective view of the locking hook of the articulated chair in the folded position.
  • Fig. 5 is a perspective view of the locking hook of the chair in the unfolded position.
  • Fig. 6 is a perspective view of the gangway locking tube when it is hung against a wall.
  • Fig. 7 and 8 are perspective views of the immobilization hook of the bridge railing.
  • a walkway 1 in the unfolded position comprising a metal platform 2 with a generally rectangular profile, on which are articulated a railing 3 and two chairs 4.
  • the railing 3 comprises a metal frame 30 in the middle of which a protective mesh 31 is welded.
  • the frame 30 is stiffened along its length by a plinth 32.
  • the articulated chairs 4 are made up of identical deformable triangles 40, the number of which (two in this case) can vary depending on the length of the frame 2.
  • the deformable triangles 40 are connected together by a tube 41 with a square or rectangular section.
  • the chassis 2 consists of two longitudinal beams 20 and 21 which are interconnected by crosspieces 22 so as to form the frame of the chassis.
  • the latter is reinforced in its length by longitudinal members 23 integral with the crossbeams 22 and on which rest wooden planks 24 providing the platform known per se for the passage of workers.
  • the longitudinal beam 20 has along its length two angles facing 25 and 26 (fig. 2) integral with one another to form a slide 25 a in which slides a support 25 b for fixing a forestay 25 c .
  • the bracket 25 is associated with a gusset 25 d and with an immobilization hook 5 allowing the pivoting and locking of the railing 3, the operation of which will be better explained below.
  • the longitudinal beam 21 is connected to the longitudinal members 23 by several cross members 21 a with a square or rectangular section making it possible to stiffen the frame of the chassis 2.
  • the longitudinal beam 21 has over its length a certain number of vertical guides 21 b with a square section for sliding graduated supports 21 c known per se. These supports allow the height adjustment and the maintenance in place of vertical forms 21 d which are retained by means of the struts 25 c .
  • the beam 21 allows the gangway 1 to be hooked against a wall 6 by means of shoes 7, known per se, which are fixed by tie rods 7 to said wall (fig. 2).
  • the crossbeams 22 are constituted by two sections 22 a and 22 b with a C-shaped section facing each other, so as to produce a transverse slide 22 c (fig. 4) whose function will be better explained below.
  • the lower part of the two ends of the longitudinal beam 20 carries an ear 20 a provided with an axis of rotation 20 b (fig. 2 and 3) around which is articulated one of the ends of a double stay 40 a belonging to each articulated chair 4.
  • This double guy 40 a has at its other end a rotation axis 40 b for the pivoting of a hollow bar 40 c with a square section, serving as a strut.
  • This end is integral with a longitudinal tube 41 which allows the chairs 4, once unfolded, to bear against the wall 6.
  • each hollow bar 40 c is secured to two circular ears 40 e (fig. 5) which slide in the slide 22 c so as to guide the corresponding articulated chair 4 in its movements.
  • a pivoting hook 8 the operation of which will be explained with reference to FIG. 5.
  • each guy 40 a folds back along arrow F1 so that the hollow bar 40 c slides by means of its ears 40 e in the slide 22 c until a retaining finger 40 d , secured to the double guy 40 a , or retained by a swivel hook 9.
  • the railing 3, once unlocked, can be folded down according to the arrow F2 on the boards 24 of the platform so as to reduce the size e of the gangway 1.
  • FIG. 4 there is illustrated the hook 9 allowing the locking of each articulated chair 4 in the folded position.
  • This hook 9 comprises a notch 9 a for the retention of the finger 40 d , as well as an inclined edge 9 b on which the finger 40 d rests in order to snap into the hook.
  • the external face 9 c of the hook 9 is integral with a handle 9 d allowing the opening along the arrow F3 of said hook in order to release the retaining finger 40 d from the double shroud 40 a .
  • the hook 9 is mounted to rotate freely at one end of an axis 90 provided on the upper face of the sections 22 a and 22 b of the chassis 2.
  • the hook 9 is retained laterally between the section 22 a and a washer 90 has welded to the end of the axis 90, while its rotation is limited by an end-of-stroke stop 91 secured to the external vertical face of the profile 22 a .
  • the hook 8 is shown allowing the locking of each articulated chair 4 in the unfolded position and more particularly for the retention of the bar 40 c of the deformable triangle 40.
  • the hook 8 is constituted by a rectangular plate 8 a provided at one of its ends with a pad 8 b mounted freely in rotation about the axis 90 of the hook 9, so that it is guided laterally in the slide 22 c, that is to say between the edges facing the profiles 22 a and 22 b .
  • Under the plate 8 a are welded two end stops 8 c and 8 d , the widths of which are such that they can penetrate into the upper free space defined above.
  • a handle 8 e On one of the edges of the plate 8 a is welded a handle 8 e allowing the manual tilting of the hook 8 in order to release the bar 40 c from the deformable triangle 40 with a view to its folding.
  • the two ends of the longitudinal tube 10 are secured to a rectangular plate 10 a mounted to rotate freely on the axis 90 common to the hooks 8 and 9 of the chairs 4.
  • the plate is in particular arranged opposite the hook 9 and to proximity to profile 22 b .
  • the longitudinal tube comprises control means 10 b , for example hooks which can be associated with chains or cables making it possible to drive said tube in a quarter-turn rotation according to arrow F4 for the bring against the crosspieces 21 a (fig. 6).
  • control means 10 b for example hooks which can be associated with chains or cables making it possible to drive said tube in a quarter-turn rotation according to arrow F4 for the bring against the crosspieces 21 a (fig. 6).
  • the frame 30 comprises a vertical post 33 whose end is shaped inclined heel 33 has a bore 33 b through which an axis of rotation 25 e fixed to the gusset 25 d.
  • the vertical face 25 f of the profile 25 comprises a sleeve 25 g crossed by an axis of rotation 5 a secured to the retaining hook 5.
  • a counter stop 5 b is welded to the axis of rotation 5 a in opposition to a retaining stop 5 c secured to the hook 5.
  • the end opposite to the retaining stop 5 c is secured to a longitudinal tube 5 d with square section.
  • the tube 5 d is connected to another locking device identical to that which has just been described, so as to synchronize the pivoting of the hooks 5 for the release of the railing 3.
