Definitions

  • the invention relates to a scaffold for building in front of facades, formed by side frames, consisting of two vertical stands which are connected by a head bolt and a foot bolt and which have a pin at one end and a sleeve at the other end for releasable plug connection with the have adjacent frames at the top and bottom and are further formed by platforms that can be hooked into the head bolts and fixed by the foot bolts of the next frames that adjoin above and by longitudinal bolts and possibly diagonal struts that can be detachably attached to the stands.
  • Facade scaffolding of this type which are generally referred to as "frame scaffolding", are known and described, for example, in DE-OS 35 46 046.
  • a disadvantage of these known frame structures is that, after their construction, the platforms cannot be removed at places where they are no longer required, because their hooks, with which they are hung on the head latches of the frame, after the next one has been plugged on Frame are clamped by its foot latch to properly block the platforms so that they are secured against lifting. In order to remove the platform, at least one frame would have to be raised until the platform is released. This is not possible at all with a scaffold erected, especially when it comes to removing platforms from the lower fields Scaffolding acts, because then the load of the scaffolding part located above this platform prevents lifting due to its corresponding weight.
  • the invention is therefore based on the object to provide means for a frame scaffold of the generic type in order to remove platforms after setting up a scaffold at locations where they are no longer required and to achieve this with the simplest possible means.
  • the stability of the scaffolding should not be affected by the removal of the platforms.
  • the invention solves the problem, because by releasably attaching the foot latch to the uprights of the side frame of the scaffold, it is possible after the construction of the scaffold without significant change to replace platforms by loosening the foot latch at least on one side and folding it away, so that the the platform underneath which is clamped by the foot bolts can be released and removed. Instead of the removed platform, longitudinal bars perform their static function.
  • node fastenings for longitudinal bars consisting of a mounting sleeve fixedly mounted on the stand for hanging the longitudinal bars and an axially displaceable on the stand in the locking position clampable safety bush.
  • the assembly bushing and the safety bushing overlap lips attached to the end of the longitudinal bolts.
  • the longitudinal ledges are expediently attached to the side of the scaffolding facing away from the building and, when attached to the appropriate height, can simultaneously take on the function of a railing.
  • the longitudinal bars on one side have the double function of a static reinforcement and a railing.
  • each scaffold bay consists of two lateral vertical frames R and an upper and lower platform P, which can also be replaced by longitudinal bars 19.
  • the longitudinal bar 19a serves as a railing and is detachably fastened to the uprights 2 of the frame R on the front front of the scaffold facing away from the facade F.
  • Diagonal struts D can also be arranged to stiffen the framework.
  • Each frame R consists, as the detail enlargement B in FIG. 4 shows, of two stands 2, a head bolt 23 and a foot bolt 1.
  • the head strut 13 can additionally be provided for stiffening.
  • node fastenings 18 are arranged on the stands, which will be described in more detail below.
  • the platform P is clamped between the foot latch 1 and the head latch 23 and thus locked.
  • a frame 24 has a pin 24 at one end and a bushing 25 at the opposite end. On the pin 24 of the stand 2, the sockets 25 of the frame R following upwards are attached.
  • the foot latch 1 of the frame R can be detached in the sense of being removable or removable or pivoting away or rotating away or pushing up.
  • Solvable in the sense of the invention thus means that the foot latch 1 is either completely removable or at least partially removable from its original position, in which it connects the two stands 2 of a frame R at the lower end to one another, as at the opposite upper end of the head latch 23 that the platform clamped by him, s. 4, is removable. Then the foot latch 1 can be reinserted and fastened in the old place.
  • the platform P has hooks 26 at the end which, in the installed state, grip over the head bolt 23 of the lower frame R and are then secured against lifting off by the foot bolt 1 of the upper frame R plugged onto the lower frame R. Only when the foot latch 1 is removed can the hooks 26 and with them the platform P disengage from the head latches 23.
  • the longitudinal bolt 19 In place of a removed platform P there are functionally two longitudinal bolts 19 which, according to FIG. 9, can be releasably attached to the stand 2 via a node attachment 18.
  • the longitudinal bolt 19 has a lip 14 at the end, which is hooked into a mounting sleeve 20 placed around the stand 2 and fastened thereon.
  • the upper part of the lip 14 extends upwards, over which the safety bushing 21 is pushed from above, which is arranged concentrically to the stand 2 and is axially displaceable on the stand 2.
  • the longitudinal bolt 19 In the position shown in Fig. 9, the longitudinal bolt 19 is secured. After pushing up the safety bushing 21, the longitudinal bolt 19 is released and can be removed.
  • Several longitudinal bars 19 can be fastened in a star shape at each node.
  • the foot latch 1 is detachably fastened to tabs 3 by means of screws 4 or socket bolts with spring lock.
  • the tabs 3 are on the stand 2 e.g. attached by welding. After loosening the screws 4 or socket bolts, the foot latch 1 can be removed.
  • a sliding sleeve 9 is attached to the ends of the foot latch 1.
  • the foot latch 1 By means of bolts 5 which snap into holes in the stand 2, the foot latch 1 can be locked on the stand 2 in different height positions. After loosening the bolts 5, the foot latch 1 with the sliding sleeves 9 is moved upwards along the stand 2, locked in any height position, whereupon the Platform can be removed, which was previously pinched by this and the opposite foot latch 1.
  • the foot latch 1 is provided at its ends with a cross bar 8, which is pivotably attached to the stand 2 by means of a screw or a bolt about an axis parallel to that of the foot bar 1. By loosening the screw or the bolt on the stand 2, the foot latch 1 can be completely removed. However, it is also possible to pivot the foot latch 1 up about the axis of the bolts, as a result of which the distance between the foot latch 1 and the head latch 23 below it increases, so that the platform can be unhooked.
  • a sliding sleeve 9 can be fastened around the stand 2 at one end of the foot latch 1. By means of this sliding sleeve, the foot latch 1 can then be pushed up along the stand 2 until the platform P is released.
  • a locking bolt 15 can be provided on both sliding sleeves 9, which engages in a corresponding bore in the stand 2.
  • an additional sliding ring 12 can be provided, on which a wedge 11 is formed or attached, which penetrates into the circumferential gap 10 between the stand 2 and the sliding sleeve 9 and prevents the bolts 5 from unintentionally disengaging from the corresponding holes in the stand 2 .
  • FIG. 18 shows the releasable fastening of the foot latch 1 to tabs 3 on the stand 2 by means of a bolt 5 with a tilting finger 6, which prevents the bolt 5 from being unintentionally loosened and thus removing the foot bolt 1.
  • the tilt finger 6 To release the foot latch 1, the tilt finger 6 must be folded in alignment with the bolt 5, whereupon the The bolt 5 is pulled out and the foot latch 1 can be removed.
  • the foot bolt can be completely removed after loosening both bolts 5, or the foot bolt 1 can be folded up around the bolt on the right side after loosening the bolt 5 on the left in order to release the platform P underneath.
  • the bolts 5 with tilt fingers 6 can be arranged either horizontally or vertically.
  • a ring 16 is attached to one end of the foot latch 1, which ring is rotatable about the associated stand 2, but is not arranged on it in a longitudinally displaceable manner.
  • this is done by means of a bolt 5 with a tilting finger 6 and in the embodiment according to FIG. 21 this is done in the manner of the knot fastening 18 for a longitudinal bar.
  • the foot latch 1 is releasably attached to the fork 28 by means of a split pin 27, which is arranged on a ring 17 around the stand 2.
  • the foot latch 1 is releasably attached at one end by means of a ratchet mechanism 7.
