Definitions

  • the invention concerns a method for assembly of a shoring tower as well as a set comprising a lifting and holding tool and a shoring tower.
  • Shoring towers can be used depending on design and load bearing capacity as working or protection scaffold for providing a work platform for workers for example at buildings as well as load-bearing scaffold or support frame for shoring beams for building a variable supporting structure for buildings, bridges or other constructions.
  • a shoring of interconnected shoring struts and supports in form of for example pipe profiles are assembled level by level until the needed height is reached.
  • commonly accessible areas or platforms are generated by means of decks mounted in the shoring, which serve for the assembly and disassembly of the shoring tower itself as well as a working platform for work on an adjoining building at for example a facade scaffold.
  • Shoring towers can have heights in which sometimes appear such strong gusts of wind that can detach or take off decks. This does not only cause a high risk of injury due to falling down decks, but also increased effort during assembly and disassembly.
  • the document EP2557252A1 discloses an assembly deck and method for safe erection of a lead bearing scaffold tower. Deck elements 12 with hooks 34 being arranged only at one front side are disclosed, wherein scaffold bars 20, 21 are mounted via articulated joints firmly to the deck element 12, i.e. detaching the articulated joint during assembly is neither possible nor intended.
  • the second railing element 16 has also hooks 36.
  • a deck element 12 can thereby be mounted on a bar of the shoring tower, namely by means of hooks 34 being directly at the one front side of the deck element 12 as well as the hooks 36 of the second railing element 16, which is mounted to the deck element 12 by articulated joint at the other front side of the deck element 12.
  • a single deck element 12 is therefore always mounted at the same time to two shoring levels (I, II) and on one side only through the railing element 16 indirectly connected to the shoring, so that wobbling can occur during accessing. Furthermore, half of the weight is absorbed by the articulated joint during accessing the deck element 12, which can result in a comparatively little life span.
  • the front side is firstly mounted with the hooks 34 on the bar in the next higher shoring level. Subsequently, the second railing element 16 is moved and mounted accordingly with the hooks 36 to the next higher shoring level.
  • deck element 12 As the deck element 12 is mounted by an articulated but not detachable joint with the railing elements 14, 16, handling and transportation to the assembly operator inside of the shoring tower during assembly is made difficult. Furthermore, a deck element 12 has a high weight due to the firmly joint railing elements. Finally, due to the above described setup, only mechanism for securing take off is implemented, like for example spring pre-loaded hooks (see paragraph [0026]) or noses 40 (see paragraph [0039]), which require additional working steps.
  • the above described features known from the state of the art can be combined alone or in various combinations and are limited by the appended claims.
  • the objection of the invention is to provide a further developed method for assembly of a shoring tower as well as a further developed set comprising shoring tower and a lifting and holding tool for conducting the method.
  • the invention is based on the following insight: one imagine a deck 1 with one or two insertion hooks 3 each at the first front side 28 and the second front side 29, wherein the insertion hook 3 of the first front side 28 is hanged up on a particularly horizontal shoring strut.
  • the deck 1 shall now with the second front side 29 be swiveled upwards to the next higher shoring level I, II, III, IV about the shoring strut 27 on which the first front side is hanged up.
  • the insertion hook 3 of the second front side 29 will inevitably hit against a particularly horizontal shoring strut 27, which is located on the opposite side of said shoring strut 27 on which the first front side (area) is hanged up.
  • the deck element 12 of the teaching of document EP2557252A1 can basically provide a hook 34 at only one front side. Otherwise, a swiveling upwards as disclosed in document EP2557252A1 would not be possible due to collision with crossbars.
  • a detachable lifting and holding tool 20 which is hookable in and hookable out of a deck and which holds the first front side 28 of the deck 1 in an assembly distance 30 above the particularly horizontal shoring (level) strut 27, the swiveling path of the second front side 29 of the deck can be shifted upwards such that a collision with an opposed shoring strut 27 can be avoided very easily.
  • it is also basically enabled to swivel the lifting and holding tool 20 through an opening of the shoring towards outside so that the swiveling path of the second front side 29 can be shifted further away from the otherwise colliding shoring strut 27. In both cases, a swiveling up can thus be enabled and therefore a very fast and easy assembly be achieved.
  • a deck 1 can be provided with a very low weight.
  • the lifting and holding tool 20 can also be reused for assembly of further decks 1, 31. Additionally, an ergonomical moving up of a deck 1, 31 can be enabled. The prerequisites for an assembly method with advancing side protection and a very high operational safety are also achieved.
  • a deck can thus be assembled very robust, which will shake very few during accessing and therefore give a safe feeling to the user during accessing.
  • a deck 1 can furthermore achieve a very high wear resistance and long life span.
  • the assembly distance 30 at substantially vertical orientation of the lifting and holding tool 20, thus in an orientation of a freely on a shoring strut 27 hanging up lifting and holding tool 20 without hooked in deck 1, amounts to at least 5 cm, preferably 10 cm, and/or preferably at most 50 cm, preferred at most 20 cm.
  • an assembly distance 30 enables a swiveling upwards of a deck 1, 31 in a next higher shoring level as well as the above described advantageous effects.
  • an assembly distance of at least 5 cm, preferably 10 cm, and/or preferably at most 50 cm, preferred at most 20 cm has proven to be very advantageous in terms of a very simple, fast and ergonomical assembly.
  • the figures 6a to 6c show exemplarily prior working steps for erection of a shoring tower 26 based on the shown embodiment examples of the method.
  • a base frame with spindle foot - shoring level 0 - is assembled on an underground.
  • the shoring struts 27 are particularly provided by separate side railings, which comprises particularly the horizontal shoring struts 27, on which a deck 1, 31 is hanged up or a lifting and holding tool 20 can be hanged up.
  • a base frame with spindle feet and side railing is shown in figure 1 .
  • shoring struts 27 for a shoring level I, II and/or with the side railings or the base frame of the next lower shoring level 0, I.
  • At least one side railing of the side railings that are assembled on the base frame is in principle an entry frame, which provides an opening that is big enough to climb into the inner of the shoring tower 26.
  • the shown embodiment examples provide exactly the space (just enough) for two decks 1, 31 per shoring level 0, I, II, III, IV to form or provide an accessible, horizontal area.
  • a deck 31 is as shown in figure 6b now by hand hanged up respectively hooked on the corresponding horizontal shoring struts 27 in the intended insertion position of the first shoring level I.
  • the deck 31 is handed over through an opening in the side railing respectively between shoring struts from outside.
  • the lifting and holding tool 20 remains idly during said insertion of the deck 31.
  • the shoring level 0 in figure 6a can also be the upper area of a shoring strut 27 or side railing of a next lower shoring level 0, which is positioned already plenty of shoring levels above the underground and on which two decks 1, 31 have been inserted.
  • the above described working steps are also for this case the same.
  • a very simple and fast assembly can thereby be enabled. Furthermore, the prerequisites for enabling a very ergonomical body posture during assembly are obtained.
  • the deck 1 can thereby be moved respectively swiveled comfortably, ergonomically and easily passing by the horizontal shoring strut of the shoring level II without getting stuck with the insertion hook 3.
  • the hanged up lifting and holding tool 20 furthermore enables moving the deck 1 with the insertion hooks 3 passing over the horizontal shoring struts 27 and a lowering of the deck 1 for a vey easy hanging up.
  • the lifting and holding tool 20 can subsequently be temporarily hanged up on the horizontal shoring strut 27 of the third shoring level III ( Figure 6f ).
  • the deck 1 can thus be inserted very easily. Through engaging (grasping) of the lifting and holding tool 20 in an upper area, an additional stooping down can be entirely avoided.
  • a preferred embodiment of the method includes that two decks 1, 31, particularly not more than two decks 1, 31, can be inserted in one intended insertion position of a shoring level 0, I, II, III, IV and/or
  • shoring tower 26 Having two decks 1, 31 per shoring level enables providing a shoring tower 26 with very low number of parts compared to a high amount of decks per shoring level.
  • the shoring tower 26 can be assembled with very few effort.
  • a preferred embodiment of the method includes that an in the first shoring level I inserted neighboring deck 31 is used as working platform for moving up the deck 1 in the next higher second shoring level II according to the steps one to six and/or a deck 1 that has been before moved up in the second shoring level II is used as working platform for moving up the neighboring deck 31 from the first shoring level I in the next higher second shoring level II according to step seven.
  • Assembly of the deck 1 in the second shoring level II can thereby be conducted in a very ergonomical body posture from the neighboring deck 31 of the shoring level I. And by working from the already inserted deck 1 in the second shoring level II, an overhead assembly of the neighboring deck 31 in the second shoring level II can thus be avoided.
  • One embodiment of the method includes that the deck 1, 31 of step one and/or step seven has been before - as step 0 - inserted by hand in the intended insertion position of the first shoring level I for providing an horizontal area intended to be accessible.
  • assembly of decks can be enabled with ergonomic body posture in a very fast and easily.
  • a preferred embodiment of the method includes that an insertion of a deck 1, 31 by hand in an intended insertion position of a shoring level I can only be conducted, when the next lower shoring level 0 is covered fully with one or more decks 1, 31 or when the shoring level I is reachable from the underground.
  • Underground means the ground, on which the shoring tower is standing. From the underground reachable means, that an assembly operator standing on the underground can well reach the shoring level I with the hands so that he can insert a deck thereon.
  • a preferred embodiment of the method includes that only every second shoring level 0, II, IV is fully covered by one or more decks 1, 31 after completed assembly of the shoring tower 26.
  • a very fast erection of a shoring tower 26 can thereby be achieved.
  • the distance between two shoring levels I, II amounts to at least 95 cm, preferably 1 m, and/or at most 1,20 m, preferably at most 1,10 m. This has proven to be very advantageous in regards of simplicity, assembly time required and the reliability of the assembly method according to the invention.
  • One embodiment of the method includes that a deck 1, 31 is only inserted in an insertion position of a first shoring level I after an advancing side protection, particularly comprising shoring struts 27 preferably of a side railing ( figure 1 ), has been assembled at least up to the second shoring level II ( figure 6b ).
  • One preferable embodiment of the method includes that exactly two lifting and holding tools 20 are sufficient to assemble all decks 1, 31 of a shoring tower 26.
  • One preferable embodiment of the method includes that the lifting and holding tool 20 can be hooked in and hooked out of a deck 1 as the lifting and holding tool 20 can be hooked in or hooked out of a lifting lock 2 of the deck 1 - for locking of a deck 1 being inserted in an intended insertion position with the hanged up shoring strut 27 against unintended taking off -, which is arranged at a front side 28, 29 of the deck 1, wherein the lifting lock 2 is configured such that the deck 1 can be lifted and simultaneously be unlocked and/or inserted in an intended insertion position and simultaneously be locked.
  • the lifting lock 2 of the deck which is arranged particularly centered at a front site 28, 29 of the deck 1, preferably at each both front sites 28, 29 of the deck 1, is configured such that the lifting lock 2 can also at a resting deck 1 fall respectively switch from a detached position ( figure 3 ) into a locked position ( figure 4 ) only by force of gravity and/or the lifting lock 2 can switch from the locked position into the detached position by lifting the deck 1 through engaging at the lifting lock 2.
  • lifting lock 2 is used as grasp point (action point or lifting point) of the deck for lifting the deck 1.

  • a deck 1, 31 can thereby be provided, which can be brought manually into the detached position from upside like downside for insertion respectively assembly or disassembly. At the same time, the prerequisite for usage of a lifting and holding tool can be achieved, which allow very fast and simple assembly or disassembly.
  • the lifting lock 2 comprises a mass plate 4 (bulk plate), which is translationally mounted by means of a vertical guide, preferably by means of a screw 7 guided in an oblong hole 6.

  • a lifting lock 2 for avoiding taking off of the deck 1, 31 from an intended insertion position is arranged particularly centered at a front side or both front sides of the deck 1,31 , preferably centered between two insertion hooks 2 for hooking of the deck 1, 31 in a horizontal shoring strut.
  • a surrounding deck frame 15 made of metal for mounting a deck plate 12 enables a deck with a very high stability and strength.
  • a side profile 16 is arranged on both long sides of the deck 1, 31 at the bottom side of the deck frame 15 in order to obtain a very robust mounting surface in insertion position as well as improved stackability.
  • insertion hooks 3 and/or a lifting lock 2 are directly mounted at a deck frame 15 in order to save space and to achieve very high stability and thus operational safety.
  • the insertion hooks 3 are preferably mounted on the deck very strongly and safe by means of a connection with a vertical extending side plate of the deck frame 15.
  • a shoring level (see figure 1 ) comprises usually exactly two decks 1, 31 in order to enable a fast assembly and disassembly.
  • At least one of the decks 1, 31 of a shoring level provides a flap 13 for climbing through the deck from above to downwards or below to upwards.
  • a flap 13 comprises a handle hole 14 in the deck plate 12 for opening from below or above.
  • a spring loaded latch with a ramp is commonly provided, which engages a latching connection with the deck frame 15 in a self-acting manner during closing as well as can be opened with an operating element that is arranged at the handle hole 14. Opening of the flap 13 is thus possible very easily from above and below.
  • the figure 3 shows a detailed view oft he lifting lock 2 in detached position.
  • a mass plate 4 of the lifting lock 2 provides an oblong hole 6 as vertical guide 6 and is mounted translationally (together with) by a screw 7, which is preferably connected to the deck frame 15.
  • a fork-shaped suspension 9 with two slide bars complements, supports respectively relieves the translational mounting by means of the oblong hole 6 and the screw 7.
  • the mass plate 4 and/or the insertion hooks 2 have weight reducing openings 11 in order to allow providing a deck 1, 31 with very low weight.
  • a L-shaped latch 8 can pivot freely about an latch rotation axis 10 that is oriented in parallel to a horizontal shoring strut 27.
  • a commonly U-shaped support arm 17 (see figure 4 ) is arranged at the bottom side of the mass plate 4, preferably being one piece with the mass plate 4 and/or extending orthogonally towards a motion path of the mass plate 4.
  • lifting and holding forces can be transmitted very easily and reliably to the deck 1 respectively the deck frame 15 and/or deck plate 12 during lifting or holding of the deck 1, 31 above the lifting lock 2 respectively the mass plate 4 of the lifting lock 2. Otherwise, these forces would be born (absorbed) only by the screw 7.
  • the lifting lock 2 can thus be unlocked very easily during assembly and disassembly through pushing the support arm 17 upwards.
  • the L-shaped latch 8 can be designed such way that the L-shaped latch 8 works as catch, which is pivotable about the latch rotation axis 10 and whose rotation axis is arranged in the turning area between an upper latch arm 18 and a lower latch arm 19 that is connected to the upper latch arm 18 under an angle.
  • the lower latch arm 19 is substantially as long as the upper latch arm 18 at equal thickness. In detached position of the lifting lock, the lower latch arm 19 rotates through force of gravity downwards and the upper latch arm 18 protrudes above that a little or at least more than the lower latch arm 19.
  • the mass plate 4 of the lifting lock 2 has two hook-in-slots 5 for hooking in a hinged manner of a separate lifting and holding tool 20.
  • the figure 5 shows a lifting and holding tool 20 with two connection hooks 25 for hooking in the hook-in-slots 5 of the mass plate 4 a hinged manner. Particularly, also two hang up hooks 21 are provided for hanging up the lifting and holding tool 20 on a shoring strut 27.
  • connection hooks 25 are designed mostly recessed and extending slanting upwards under an angle towards a horizontal in vertical position of the lifting and holding tool 20 (as shown in figure 5 ), the lifting and holding tool 20 can be inserted very easily in the hook-in-slots 5 of the mass plate 4 in locked position of a deck 1 being placed in an intended insertion position as the lifting and holding tool 20 after dropping (being placed) on the horizontal shoring strut 27 can be pushed in direction towards the deck 1, 31.
  • the deck 1, 31 When the deck 1, 31 is lifted through the lifting and holding tool 20, the deck 1,31 is simultaneously secured by the hooked in a hinged manner connection against detaching also in case of unintentionally releasing and falling down of one side of the deck 1, 31.
  • the lifting and holding tool 20 has two in parallel arranged rods, which are connected through horizontal connection bars 20, 23, 24.
  • the horizontal connection bars 20, 23, 24 are further arranged and designed such that they form at the same time an lower handle 22, middle handle 23 and upper handle 24.
  • Figure 1 shows a shoring tower 26 with a deck 1, 31, wherein the shoring tower 26 is a load-bearing scaffold or support frame for shoring a beam for building a hall ceiling or a bridge and/or provides a head jack at the upper area, particularly fork-shaped head jack, with adjustable spindle for shoring a beam or other components to be shored.
  • the connection hook 25 of the lifting and holding tool 20 is partly or mostly recessed and/or when the lifting and holding tool 20 being hanged up then the connection hook 25 extends slanting upwards towards a horizontal under an angle of at least 4 degree, preferably 8 degree, preferred 12 degree and/or at most 60 degree, preferably 50 degree, preferred 40 degree.
  • connection hook 25 in an opening of a deck 1, 31 can thereby be enabled. Furthermore, a very reliable and detaching-secured (-resistant) connection to the deck can be achieved also during swiveling in both directions.
