Definitions
- Ladder scaffolding with a single ladder There are many different designs with the ladder as the basic element for scaffolding and work platforms.This not only focuses on the flexibility and safety of these devices, but increasingly also on cost-effective production and fast, economical installation.
- DE 195 00 705 C2 and DE 198 07 161 AI work platforms are known, wherein a ladder is attached to a mobile frame by means of struts, and the enclosed work platform can be inserted or converted into any working height with a cable pulling device.
- the new work platform consists of a leaning ladder, preferably a three-part cable puller, in which the required stability is achieved with a widened base and a widened wall spacer shaker
- the height of the work platform is adjusted by means of the parts of the cable puller that can be pulled out by means of a cable, and the horizontal movement is carried out using rollers
- Figure 1 shows the ladder scaffold described on a building
- Figure 2 shows the ladder scaffold of Figure 1 rotated by 90 °
- Figure 3 shows the wall spacer with the wall rollers and the rolling part
- Figure 4 shows the wall spacer shaker of Figure 3
- Figure 5 shows the widening of the foot with the adjustable feet
- Figure 6 shows the foot extension of Figure 5
- Figure 7 shows the device for the cable pull
- Figure 8 shows the device of Figure 7, turned 90 °
- Figure 9 shows the pulling weight with the pulling cable
- Figure 10 shows the train weight of Figure 9 in plan view
- FIGS. 1 and 2 show the new ladder scaffold, a ladder (1) being provided with a base widening (2) and a widened wall spacer (3), being set against a building, and the enclosed work platform (4) using a cable pull device ( 5), into which the rungs of the ladder can be inserted and converted.
- the known cable pulling device (DE 198 07 161 AI) is used for this purpose.
- the slight deviations from this known cable pulling device (DE 198 07 161 AI) due to the adaptation to the new Ladder scaffolding are described below
- the wall spacer shaker (3) represented by FIGS. 3 and 4, consists of two pairs of tubular profiles (10, 11) which are pivotally attached to the ladder rungs (48, 49) on one side, and in the form of scissors, via the connecting tube (13) and by means of bolts ( 14) secured, connected to each other
- the pair of tubular profiles (11) is provided with a telescopically extendable pair of inner tubes (12) to which the widening (16) is attached.
- the widening (16) extends beyond the width of the worktop (4) and is provided at the ends with a wall roller (15) and a roller part (17).
- the roller part (17) consists of a pivoted reversing lever (57) , which is attached approximately in the middle between the two ends of the widening (16), the lever arm on the side facing the building with at least one steering roller (53) and on the second side with a hook (54) for hanging one Operating ropes is provided
- the foot extension (2) consists of a rectangular tube (19), which is equipped with two welded rectangular tubes, which serve as a spar holder (20), and with two tabs (21) for attaching the ladder (1), whereby the attachment the Lerter after insertion into the spar holder (20) through a mounting tube (22) through the holes in the Tabs (21) and through the lower rung, which is provided on one side with a stop (55) and secured on the second side with a locking hook (56)
- the rectangular tube (19) is with the adjustable feet (23, 24) equipped with rubber feet or other materials
- two extendable casters (26, 27) are installed in the rectangular tube (19) of the foot extension (2), which can be extended with the handle (25) from the recesses provided in the rectangular tube, the rollers (26 , 27), which are mounted on deflection levers (31, 32), by means of a steel cable (30) which is guided over the cable pulleys (28, 29), perform a rotary movement downwards, and thus the work platform on the rollers (26, 27)
- the choice of lever arm on the bell crank (31, 32) reduces the force required for the user.
- the handle (25) sits in a recess in the foot extension (2), has a hook and is used for the duration of the Procedure of the work platform pulled out and hooked into a ladder rung
- the advantages of this expansion are that the tensile force acts simultaneously on both rollers (26, 27) and that the steel cable (30) with the handle (25) in the ladder rung, the operator becomes noticeable when climbing up, so that the lowering of the working platform onto the safe adjustable feet cannot be forgotten.
- the standing feet (23, 24) for the purpose of the exchange are relieved, for example if the work platform comes from the area of floor slabs on the grown soil and earth spikes are required
- the Seilzugvor ⁇ chtung (5) is attached to the ladder rungs on the lerter head, the hollow profiles (33) are pivotally attached m the top rung and the hollow profiles (34), which are connected to the cross tube (38), can be telescoped into the hollow profiles (33 ) are inserted
- the pair of struts (35) is attached to the second rung from above and supports the pair of crossbars on the hollow profiles (33)
- the rope pulley (36) is fastened to the cross tube (38) and the rope pulley (37) to the cross tube (39) and both rope pulleys (36, 37) guide the pull rope (50) in the area between the Draw weight (6) and the locking hook (7)
- the extendable tubular profiles (34) are secured with locking pins (40)
- the pull weight (6) consists of a steel block (41), on which a coil (43) is fastened by means of a bolt (42).
- the coil (43) serves to receive the pull rope (50) and to adjust the rope length, depending on the Overall height of the working platform, and is provided with a handle (44) in which a bore (45) for guiding the traction cable (50) is provided.
- the spool shaft is provided with a crank (46).
- Hooks (58) are attached to the traction weight (6) attached so that it can also be used as a set-up aid in the learner's foot
- the user places the lerder on the floor and fastens the foot bracket (2), the wall spacer (3) and the cable pull device (5) to put on the foot bracing (2) we lifted the lerter's foot and the spar supports (20) pushed over the lerter's foot, pushed the fastening tube (22) through the holes in the tabs (21) and through the cavity of the bottom rung and with de m Locking hook (56) secured
- the wall spacing shaker (3) is inserted and fastened on two ladder rungs according to the wall spacing chosen and, after adjustment, both via the scissor-type connection of the rectangular profile pairs (10, 11) and via the telescopically extendable inner tubes (12) , locked and secured with the bolt (14)
- the Seilzugvor ⁇ chtung (5) is designed so that it only has to be unfolded by the tubular profile (33) with the
- the lerder (1) is set up and attached to the pair of wall rollers ( 15) applied to the building and brought to the desired overall height with the help of the rope, the speakers rolling over the wall rollers (15) of the wall spacer (3) on the building.
- the user pulls the handle (25) out of the foot extension (2) and hooks the fully extended handle (25) into the provided ladder rung so that the working platform is on the rollers (26, 27).
- the steering roller is attached to the rolling part (17) by means of a rope that is attached to the hook 54 and extends to the floor, printed on the building wall, whereby the pair of wall rollers (15) lifts off the building wall.
- the user can roll the work platform along the building Stes occurs m the reverse order List of reference symbols ⁇ : conductor 54 hooks
