Definitions

  • the invention relates to a formwork aid, in particular for slab formwork with several formwork panels, which have stiffening webs or the like at their edges, and also their mutual connection, which protrude at least in sections on the flat side of the formwork panel facing the concrete, the formwork aid being attachable to and also on a formwork panel attacks the second formwork panel so that one formwork panel initially holds the other when it is released.
  • stripping aid of the type mentioned, in which not only during, but also after the complete tilting of a formwork panel it remains firmly and securely connected to the other formwork panel, so that the folded formwork panel can even be released briefly in this position and left hanging.
  • the stripping aid should also be usable in the manufacture of a slab formwork in the opposite direction without the risk that the formwork panel then to be lifted up can be unintentionally lifted out of its support in the area of the formwork panel already in the up position.
  • a stripping aid of the type mentioned is characterized in particular in that it has two socket pins, one of which can be attached to the edge web of the first formwork panel and the second of which is flush with the edge web of the other formwork panel, and that od between the two bolts. Like. At least one joint is provided. With such a stripping aid, a firm and form-fitting connection can be established between two adjacent formwork panels at their mutually aligned edge webs, so that the one formwork panel can then be tilted between the two bolts after loosening around the joint mentioned, without the risk of doing so. that it can slip out of its edition.
  • a bolt is firmly connected to it and has at least one projection running transversely to it for insertion into a keyhole-like perforation and for locking in the holding position.
  • Formwork panels with keyhole-like perforations in their edge webs are described for example in the aforementioned DE-PS 21 37 505 and the rotatable bolt can correspond at least with regard to its fastening end to the bolt described in this DE-PS 21 37 505. This also simplifies production.
  • an embodiment of the invention of its own worthy of protection can consist in that the stripping aid can be designed as an angle piece, that a preferably fixed bolt protrudes approximately at a right angle to the plane formed by the angle legs at the free end of the one angle leg and that at the end of the angle leg another angled leg, a joint and a tab fixed therewith are arranged, which carries the second, in particular rotatable pin in its end region remote from the joint.
  • the angle piece thereby facilitates attachment in cases in which the stripping aid has to be gripped over a transverse web which runs transversely to its course and to the webs receiving it.
  • Embodiments of the invention are the subject of further claims. Especially when combining individual or all of the measures described above or contained in the further claims, there is a stripping aid with which a scarf to be stripped and swung down panel can be fixed securely and positively, but still swiveling easily to a remaining panel.
  • the folded formwork panel can possibly even get stuck initially without it being possible for it to fall out of its holder unintentionally.
  • this formwork panel must be pulled off the side of the retaining bolts or, conversely, the bolts must be pulled out laterally relative to the formwork. This is only possible if the formwork panel is held at the same time, whereas in the case of a freely suspended formwork panel, its weight on the bolts results in sufficient friction for a secure fixing in this position.
  • Due to the design of the stripping aid as an elbow with an attached tab there is a height adjustment of the element away from the concrete at the same time when striking and the folded formwork element hangs so deep that it can no longer come into contact with the edge webs of the still horizontal formwork element.
  • a stripping aid designated as a whole with 1 can be used particularly advantageously in connection with slab formwork, which can be composed of several formwork panels 2 and 3. Especially in Figures 2 and 3 it can be seen how the formwork of ceiling formwork panels 2 and 3 can be carried out in a manner yet to be described with the aid of the formwork aid 1 according to the invention, without a support with a lowerable at the contact point 4 of the formwork panels 2 and 3 Supports head or the like.
  • the stripping aid 1 has two socket pins, namely a socket pin 5 and a further socket pin 6, one of which can be attached to the edge web 7 of the first formwork panel 2 and the second of which can be attached to the flush web 7 of the other formwork panel 3. This arrangement can also be clearly seen in FIGS. 2 and 3. Between the two bolts 5 and 6, a joint 8 is provided on the stripping aid 1, the function of which can be seen above all in FIG. 3.
  • One bolt 5 is fixedly connected to the stripping aid 1 and the second bolt 6 arranged parallel thereto is rotatable.
  • This rotatable bolt 6 has at least one, in the exemplary embodiment two mutually offset by 180 °, transverse to the bolt 6 itself protrusions 9, which can be inserted into keyhole-like perforations analogous to the holes 10 shown in Figures 2 and 3 and through one Twisting the bolt 6 cause a lock in this position.
  • This lock can be seen, for example, in FIG. 4.
  • the stripping aid 1 has an angle piece 11, the fixed bolt 5 preferably projecting at approximately the right angle to the plane formed by the angle legs 12 and 13 at the free end of the one angle leg 12.
  • a pivotally fastened tab 14 is arranged, which carries the second, in the exemplary embodiment the rotatable pin 6 at its end region remote from the joint.
  • the angle piece 11 has legs 12 and 13 which are at right angles to one another.
  • the fixed bolt 5 is smooth and free of protrusions, so that its insertion and later also the unhooking of the other hanging formwork board are smooth.
  • the protrusion-free bolt 5 according to FIG. 4 is longer than the rotatable bolt 6 provided with the stop projections 9 in order to provide increased security against unintentional unhooking.
  • the rotatable bolt 6 is captively attached to the stripping aid 1 and the tab 14 carrying it engages between a first stop 15 and the second stop 9 of the bolt 6 which fits into a keyhole-like perforation 10.
  • the tab 14 can be fixed in the manner shown in FIG. 4 by inserting the bolt 6 into an edge web 7 and rotating the bolt 6.
  • the rotatable bolt 6 has a handle 16 on the side facing away from a formwork web 7. This makes it easier to rotate and at the same time provides an orientation indicator for the projections 9 running in the same direction, the arrangement being such that when the handle 16 is vertically downward the bolt 6 is locked.
  • the fixed bolt 5 can be rotatably and detachably attached to a formwork panel 2 or a perforation 10 in the edge web 7 thereof. It is sufficient to insert the entire stripping aid device in the direction of this bolt 5 from the side in any orientation relative to the formwork panel. Then the second bolt 6 with its stop projections 9 can be brought into the correct position relative to the keyhole-like perforation of the neighboring formwork panel and can also be inserted, as a result of which the bolt 5, which is initially inserted only in part, is completely in the perforation can occur. By locking the bolt 6, the entire stripping device 1 is first attached. The insertion is facilitated in that at least one, preferably both bolts 5 and 6 each have a tapered end 17.
  • the elbow 11 is formed from two flat iron welded together, which represent the legs 12 and 13.
  • the pivotable bracket 14 with the preferably rotatable bolt 6 engages on the side of the angle leg 13 on which the other angle leg 12 is also welded.
  • the surfaces of these parts facing the formwork thus lie in the same plane. This can cause any canting. The like can be avoided effectively.
  • the length of the angle leg 13, which extends approximately parallel to the formlining in the position of use, from the center of the then approximately vertical angle leg 12 to the center of the bracket joint 8 corresponds approximately to the distance between perforations 10 on mutually aligned edge webs 7 of adjacent formwork panels 2. This ensures that in 2 the tab 14 in parallel to the angle leg 12. It has already been mentioned that with slight deviations in the spacing of the perforations, a different angle is made possible by the joint 8.
  • the length of the angled leg 12, which extends approximately at right angles to the formlining in the use position, from the center of the bolt 5 to the narrow side 13a of the second angled leg 13 facing the formwork is somewhat larger than the distance between the perforations 10 in the edge webs 7 of the formwork panels 2 from the free edge 7 a of these edge webs 7. In the starting position according to FIG. 2, the angle leg 13 is thus completely below the edge webs.
  • stripping aid 1 If the stripping aid 1 is fixed in the form shown in FIG. 2, the fastening bolts (not shown in more detail) can be loosened in the area of the contact point 4 or at other points on the formwork panels 3. As a result, this formwork panel 3 is finally only held by two stripping aids 1 located opposite one another at the edges. It can now be detached from the concrete surface and folded down into the position shown in FIG. 3, the pivoting movement taking place around the joint 8 and, due to the angular configuration, also being lowered in the area of the contact point 4.
  • the formwork panel to be stripped with its edge web 7 located in the area of the contact point 4 can initially start slide along the other edge web of the fixed formwork panel 2 or even be lifted off a little bit while at the same time tilting downwards becomes. It then hangs accident-proof in the position shown in Fig. 3, in which the two bolts 5 and 6 and the joint 8 are approximately vertically below each other. Then the formwork panel 3 can be removed laterally from the bolt 5 holding it.
  • the angular design of the stripping aid also has the advantage that the entire device can act either on the outside or on the inside of formwork panels, because the essentially horizontal angle leg 13 can reach under the edge webs of the contact point 4 extending transversely to it.
