  • the Joint lath is an essentially flat, thin-walled Element that is similar to a thin sheet of metal has a certain inherent rigidity.
  • This shuttering element can be penetrated by cross dowels, which are made of Steel bars are formed and with their longitudinal extension arranged transversely to the clamping plane of the shuttering element are.
  • the object of the invention is a formwork element To provide, which is the formwork of a Component relieved.
  • finished parts should also with an easier connection option to be provided.
  • the formwork element is designed as lost formwork and has a facing away from the material to be shuttered Outside and one of the material to be shuttered facing inside.
  • the formwork element has at least two essentially on its outer surface flat partial surface and is on the inside as a plate formed, the partial surfaces on one protruding on the outside over the plate are arranged. Is between the faces at least one indentation that acts as a mortar pocket or deepening. From the outside (3) to Inside extends at least one receptacle for an anchor, the recording in the area of the indentation or the recess is arranged.
  • the formwork element is inherently stable and can be from absorb the generated material. by virtue of the plate on the inside can also become one certain forces are absorbed that act on the Act on the edge of the formwork element. So that can Formwork element loads before the concrete hardens Take up perpendicular to the finished part.
  • the formwork element has the advantage that for insertion No special formwork is required for anchors is and that compared to conventional reinforcement connections to be dispensed with on a storage box can.
  • Prefabricated parts such as prefabricated walls and prefabricated ceilings produce.
  • the anchor and here in particular the anchor loop in any position can be arranged in the afterwards for installation certain location. This is possible because that Formwork element even in the manufacture of a finished part only needs to be supported against displacement.
  • the formwork element can advantageously be made of fiber concrete or consist of polymer concrete.
  • Such a formwork element also has the advantage that through the special shape of the mortar bag when using a filling compound that absorbs tensile forces on additional reinforcement in the area of the butt joint can be dispensed with altogether. Two finished parts of a building or part of a building then by a filler mass transferring tensile forces connect with each other.
  • a finished part with such Formwork element object of the invention the Prefabricated part designed as a wall part or as a ceiling part can be.
  • the formwork element can essentially over the entire width (thickness) of the finished part extend.
  • the object is also a building or parts of a building with a finished part.
  • Fig. 1 is a finished part 1 with one as lost Formwork formed formwork element 2 made of fiber concrete shown in cross section.
  • the formwork element 2 has an outer side facing away from the material 4 to be formed 3 and one facing the material 4 to be shuttered Inside 5 on.
  • the formwork element 2 is sufficiently stiff to withstand the filling the pressure occurring essentially without To withstand deformation.
  • the material is suitable here especially fiber concrete or polymer concrete.
  • the backfilling usually takes place in a precast plant, for what the formwork element arranged on a formwork table and for example using magnetic mounts or otherwise on this in the desired one spatial alignment is attached.
  • the formwork element 2 has on its outside 3 two substantially flat partial surfaces 6, 7, the on one each rising above the outside 3 Projection 92, 93 are arranged and a flat, flat Conclusion forms. Due to the partial areas 6, 7 can be a butt joint with another, not shown Precast are manufactured, which the usual requirements. The outside points to this of the formwork element is sufficiently rough Surface to ensure good adhesion of the mortar or to enable another casting compound.
  • the inside 5 of the formwork element 2 is with connecting elements 8 for producing the positive connection provided with the filling material.
  • These are the connecting elements 8 molded onto the formwork element 2 and made of the same material and at least form a groove 9, possibly with an undercut, behind which the material to be filled penetrates in a flowable state and fills the groove.
  • the formwork element 2 is at least one of the outside 3 to the inside 5 extending receptacle here in the form of an opening 10 for one not shown anchor available, here by a dashed line Line is indicated as the breakthrough 10 is not in the cutting plane.
  • the formwork element 2 is essentially a plate 90 formed with two partial surfaces 6, 7, between which essentially one that acts as a mortar pocket in the middle Groove 11 as an example of a depression or indentation is arranged.
  • the groove 11 tapers to the outside of the formwork element conical.
  • groove 11 can several indentations be provided by one another less deep groove are connected to the mortar by one Inversion into the next indentation flows in to let.
  • the groove 11 can also be wide and deep vary over the length of the formwork element to in in certain areas the indentations for receiving Anchoring and in other areas the flow channel for the To form mortar or the filling compound, as below in 2 shown.
  • the formwork element has such a thickness that in the opening guide surfaces for the anchor are formed.
  • the typical thickness or wall thickness of a Formwork element 2 made of fiber concrete lies in Range of plate 90 between 5 mm and 30 mm, where Usually widths of 50 mm to 800 mm are produced can be. The most common widths are in the range from 100 mm to 500 mm.
  • the length of a formwork element from fiber concrete is theoretically arbitrary, because that Formwork element preferably manufactured as an extruded part becomes. In practice, formwork elements delivered in standard lengths, about 3 m long, and then in Work cut to the lengths actually required.
  • the boundary surfaces a support bearing when the anchor is inserted for the anchor legs or, if necessary, for additional ones Adaptation elements.
  • the surfaces form the anchor leg and the boundary surfaces the opening 10 a sealing gap for the still flowable concrete, which prevents it from escaping becomes.
  • punched out or punched out can be different geometries can be realized, for example, a punching lead to conical or stepped guide surfaces. They are also star-shaped or polygonal Cross sections conceivable, can also be corrugated Direction of the central axis of the opening are generated. This allows the properties regarding the Adjust the bracket of the anchor legs.
  • guide surfaces lying outside the opening be provided for the anchor legs, for example in the form of additional ribs in the longitudinal direction, which, however, are not shown.
  • an attachment option can be on the outer surface for a holding device of the formwork element be provided on the formwork table, for example by intervening in an undercut having mortar pocket in which the holding device is pinched.
  • the projections 92, 93 for limiting the mortar pocket 11 each have a cavity 94, 95. Thereby the heat transfer of the formwork element becomes clear reduced.
  • edge surfaces 96 of the edges of the formwork element 2 and the formwork elements described above formed obliquely towards the partial surfaces 6, 7 his.
  • trained fillet 97 or the undercut plastering or filling is favored.

  • the anchor loop 22 can also be inserted into the groove 11 be used, for example for transport purposes. You can do this additional holding pieces can also be used, which fix the anchor loop in this position and which ones can be solved. These holding pieces can either be inserted into the opening 10 or in another Interact with the formwork element and the anchor.
  • armature 31 of a reinforcement is shown, the has two legs 32, 33, which through two openings 10.1, 10.2 are inserted.
  • Fig. 3 is opposite Fig. 2 shown rotated by 90 °, so that Breakthroughs 10.1, 10.2 actually in the longitudinal direction of the formwork element lie side by side. It is nevertheless possible, the breakthroughs also within the mortar pocket to be arranged perpendicular to the longitudinal direction.
  • FIG. 5 is another formwork element 50 with a flat outer surface shown without groove, which one Has opening 10 for receiving an anchor. Although no mortar pocket is formed here, this formwork element 50 with a mortar pocket having counterpart according to FIGS. 1 to 4 used as long as the dimensions of the anchor are taken into account become. Otherwise, this formwork element the other features of that shown in Figs. 1-3 Formwork element 2 have.
