Description

(1) The invention is described in details in the following with figures schematically showing embodiment examples of a deck for a shoring tower and embodiments with references to the figures as well as further preferable embodiments.

(2) It shows

(3) FIG. 1: Deck with flap

(4) FIG. 2: Lifting lock in detached position

(5) FIG. 3: Lifting lock in locked position

(6) FIG. 4: Lifting lock in locked position

(7) FIG. 5: Lifting and holding tool that is hooked in a hinged manner

(8) FIG. 6: Shoring tower

(9) The FIG. 1 shows a deck 1 for forming an accessible area in a shoring tower 26, which can be used for fabrication or reconstruction of buildings

(10) A lifting lock 2 for avoiding taking off of the deck 1 from an intended insertion position is arranged particularly centered at a front side or both front sides of the deck 1, preferably centered between two insertion hooks 2 for hooking of the deck in a horizontal shoring strut.

(11) A surrounding deck frame 15 made of metal for mounting a deck plate 12 enables a deck with a very high stability and strength. Particularly, a side profile 16 is arranged on both long sides of the deck 1 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.

(12) Particularly, insertion hooks 2 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.

(13) The insertion hooks 2 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.

(14) A shoring level (see FIG. 6) comprises usually exactly two decks 1 in order to enable a fast assembly and disassembly.

(15) At least one of the decks 1 of a shoring level provides a flap 13 for climbing through the deck from above to downwards or below to upwards. Preferably, such a flap 13 comprises a handle hole 14 in the deck plate 12 for opening from below or above. For ensuring that the flap 13 is not unintentionally opening, 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.

(16) The FIG. 2 shows a detailed view of the 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 with very low weight.

(17) When the mass plate 4 is hold against the force of gravity in an upper position (see FIG. 2), which is defined by an upper end stop of the oblong hole 6, i.e. in detached position of the lifting lock 2, a L-shaped latch 8 can pivot freely about an latch rotation axis 10 that is oriented in parallel to a horizontal shoring strut.

(18) A commonly U-shaped support arm 17 (see FIG. 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. Therewith, 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 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. Furthermore, the lifting lock 2 can thus be unlocked very easily during assembly and disassembly through pushing the support arm 17 upwards.

(19) When the mass plate 4 is released, it will fall by forces of gravity in the lower position (see FIG. 3), which is defined by an upper end stop of the oblong hole 6. The latch 8 is thereby rotated by means of the down moving mass plate 4 until the mass plate is planar adjacent (in direct contact) to an upper latch arm 18 and thus blocking it from rotation. The lifting lock 2 is then in locked position (FIGS. 3 and 4). At the front side of the deck, the lower latch arm 19 protrudes in locked position such that the lower latch arm 19 can reaching under a horizontal shoring strut for locking the lifting lock 2.

(20) 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.

(21) When the deck 1 is let down in detached position (FIG. 2) in direction towards the intended insertion position, at least the lower latch arm 19 passes by a horizontal shoring strut. However, the upper latch arm 18 can be already due to its protrusion be pushed upwards by the horizontal shoring strut. By means of a releasing of letting down the mass plate 4, a rotation of the latch 8 respectively the catch can be accomplished in every case such that the lifting lock 2 and thus the deck 1 is secured reliably against unintentionally taking off by means of locking with the horizontal shoring strut.

(22) In order to enable a very easy lifting and holding of the deck 1 through the lifting lock 2 respectively the mass plate 4 of the lifting lock 2, the mass plate 4 has two hook-in-slots 5 for hooking in a hinged manner of a separate lifting and holding tool 20.

(23) The FIG. 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.

(24) Because the 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 FIG. 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 can be pushed in direction towards the deck 1.

(25) When the deck 1 is lifted through the lifting and holding tool 20, the deck 1 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.

(26) 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. By that way, assembly and disassembly under usage of the holding and lifting tool 20 is possible that enables a very easy, ergonomical and effort-saving assembly and disassembly.

(27) FIG. 6 shows an embodiment of a shoring tower 26 with a deck 1, wherein the shoring tower 26 is a load-bearing scaffold or support frame for shoring a beam for building a variable supporting structure 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.
