- the present invention relates to a spacer element for supporting two mutually parallel supported on ceiling supports Jochhölzern a slab formwork and a fall protection system for a slab formwork with the spacer element.
- the object of the invention is known spacer elements for
- a spacer element for supporting two parallel running on ceiling supports supported yokes of a slab formwork in a transverse direction transverse to the Jochhölzern and transverse to the ceiling supports a beam element with two opposite end sides, where bearing elements for absorbing transverse forces in and against the Transverse direction are arranged from the yoke woods.
- the specified spacer element according to the invention comprises holding elements on the end sides of the beam element for fastening a network.
- the specified distance element is based on the consideration that when building a slab formwork of the fitter first builds the framework with the floor props, the Jochhölzern and the spacer elements and then hangs on the scaffold the actual formwork ceiling. When laying the formwork ceiling are high demands on the
- the spacer elements have a very small distance from each other. This has the advantage that the fitter could grab a neighboring spacer element in a fall.
- the design has a high number of parts, which are very time consuming to assemble. The leash limits beyond the range of motion of the mechanic, which further increases the time required when placing the shuttering ceiling in the air.
- the specified distance element goes here with the suggestion
- Holding elements arranged on the bearing elements In this way, the network with the largest possible area can be spanned.
- the holding elements are formed integrally with the bearing elements. In this way, the holding elements are fixed to the bearing elements held and provide a very high hold for the network.

- Positive locking element must be attached.
- a loop-shaped design of the suspension element would be conceivable, in which case the network would have to be hung for example by means of carabiners.
- each hooking element comprises a further hook, wherein the hooks are arranged in each suspension element anti-parallel and spaced from each other.
- the two anti-parallel hooks secure the hinged net against accidental snags
- the bearing elements are attachable to the yokes and on the
- anussient development of anussient spacer element include the sliding on the yoke bearing elements a Fixation point for the attack of a fixing agent, which fixes the bearing element against displacement on the yoke on this.
- Fixing means may be a screw, a nail, a rivet or the like. With the fixative is in use of the network, if an installer falls into the network, prevents the carrying the network
- Fall protection system for a ceiling circuit two parallel to each other carried on ceiling supports yoke and two the yoke timbers in a transverse direction transverse to the yoke and transverse to the floor supports supporting specified spacers.
- the two spacers should always be spaced less than 2.50 meters apart
- a method for securing a fitter on a slab formwork when placing a shuttering slab on the slab formwork comprises the steps of: setting up the slab formwork by erecting ceiling supports and connecting the slab props with yoke beams in a longitudinal direction transverse to the slab props and connecting the slab props with spacers in a transverse direction transverse to the floor props and transverse to the yoke timbers and attaching a net to the erected one
- Ceiling formwork at least halfway up the floor supports such that a spanned by the transverse direction and the longitudinal direction and limited by the yoke wood and the spacer elements surface is covered by the network.

- Pipe part 40 Each passage opening 32 of the row of holes 42 can be congruent over the passage opening 32 at the end of the first sub-pipe 38, into which the second sub-pipe 39 is inserted. In this way, the two sub-pipes 38, 39 can be fixed to one another in different axial positions with a securing bolt 43.
- a securing bolt 43 At the first tube part 40 opposite end of the second
- Pipe part 41 is another passage opening 32 which acts in the same manner as the passage opening 32 at the other end of the telescopic rod, which is why to dispense with an extra description.
- the securing bolt 43 has a bolt head 44, from which the actual can be inserted into the passage openings 32
- Bolt element 45 extends away.

- the bearing elements 26 are placed on the beam member 24 by the Aufsteckhülsen 31 are inserted into the ends of the telescopic tube 38, 39.
- a fixing means 49 such as a screw, a nail or the like driven into the yoke 18 behind it, so that the individual spacer elements 22 in the
- the net 27 is suspended from the holding elements 33.
- the net 27 has a peripheral outer cable 50, on which several smaller meshed cables 51 are held inside.
- the outer cable 50 is used to hang the
- Net 27 inserted into the distance 37 between the two hooks 34, 35 of the holding element 33 and then inserted through the hook openings 36 in the hooks 34, 35. After this has been done on all support members 33, the net 27 is suspended, and the yokes 18 may be entered by the installer to design the formwork ceiling.

- Fork element 16 in this case has the above-mentioned
- the floor supports 12 can be connected to the spacer elements 22 and only then the yoke woods 18 can be placed on the floor supports.
- the order is arbitrary here.
- Another advantage of the alternative slab formwork is a reduced number of parts because always at the same time two slip-on sleeves 31 are arranged on a base plate 52.
- the spacers 22 thus produced can no longer be positioned arbitrarily, because a plurality of spacer elements 22 are mechanically connected to one another by the common base plate 52.
- the nets 27 can be attached to the holding elements 33 in the form of the eyelets 54 in FIG. 8, for example via snap hooks.
- the holding elements 33 could also be attached to every other place of the slab formwork 1. That's the way to go
