Definitions

  • the invention relates to a formwork element for the shell concrete construction, with two spaced apart and mutually parallel heat-insulating side plates made of plastic, each having on an upper narrow side and a lower narrow side projections or corresponding recesses for connecting the formwork element with other formwork elements and a plurality between the Side plates arranged connecting elements.
  • the invention also relates to a formwork of several such formwork elements.
  • Another formwork element is in the prior art by the FR-A-2 840 632 known.
  • the side walls are connected to each other with horizontal sinusoidal iron bars and vertical inserted into the side plates iron bars.
  • the formwork elements could be mounted at the place of use so that a transport with a smaller volume is likely to be possible. An assembly site would be comparatively expensive here.
  • the EP-A-0 562 589 discloses a formwork element made of foamed hard plastic plates, in which these plates are connected by webs firmly together. Again, there is the disadvantage that incurred in a transport over a longer distance due to the air space between the plates comparatively high transport costs.
  • the invention has for its object to provide a formwork element of the type mentioned, which can be transported with less airspace and quickly and easily mounted at the point of use.
  • the formwork element should nevertheless have a high stability.
  • the connecting elements are U-shaped stirrups, which is anchored in each case with one of two tabs in a slot in a top or bottom of one of the two side plates.
  • the two side plates are connected to each other by means of stirrups.
  • stirrups can be very quickly and yet easily plugged into the connecting side plates during installation at the point of use.
  • several such stirrups are inserted at the top and several at the bottom in the side plates. This results in a particularly high stability.
  • the connecting elements each have a substantially straight web between the two tabs.
  • Such fasteners can be made particularly simple and inexpensive punched parts made of sheet metal.
  • the webs are preferably substantially perpendicular to the planes of the side plates in the mounted state.
  • said webs each extend substantially in a plane of the upper or lower narrow sides.
  • said webs are recessed at a distance from these planes. This distance is preferably a few mm, for example 10 mm. Due to the recessed arrangement of the webs, no unevenness is created in these upper sides or lower sides, and the connection of adjacent formwork elements is not hindered as a result.
  • the formwork elements can thus continue to be connected to one another, for example by means of corresponding nubs and recesses.
  • the tabs of the stirrups are each provided with barbs, with which the connecting elements are anchored in the side plates.
  • the tabs are inserted in slots of the side panels. These slots are preferably designed such that they are widened when inserting the connecting elements and thereby incorporate said hooks in the side plates substantially insoluble.
  • the slots can conically narrow, for example, from top to bottom. This also applies to the mentioned tabs.
  • the connecting elements which are inserted into the upper side of the formwork elements are arranged offset to the connecting elements, which are inserted from the bottom in the formwork element. This staggered arrangement results in a particularly high stability.
  • the invention also relates to a formwork of a plurality of formwork elements of the type mentioned. According to a development of the invention is provided in such a formwork that it has at least one formwork element which has firmly foamed fasteners.
  • the formwork element with the firmly foamed-in connection elements is in this case preferably arranged in a lower region of the formwork.
  • the side plates can be easily and quickly connected to each other after transport at the point of use by inserting the stirrups.
  • the stirrups can be made very easily and inexpensively, a particularly cost-effective design can be achieved.
  • the invention allows not only an economical, but also ecologically advantageous construction.
  • Shuttering element 1 shown has two side plates 2 and 3, which are arranged parallel and spaced from each other.
  • These side plates 2 and 3 may be single or multi-layered and are made of a thermally insulating plastic, for example a foamed plastic, for example polystyrene.
  • the side plates 2 and 3 are different in thickness so that the dew point in the building is in the outer and thicker shell. The difference in thickness is preferably at least 1 cm.
  • These side plates 2 and 3 each have an upper narrow side 4 and a lower narrow side 5. Further, they each have an outer side 8, an inner side 9 and two opposite end surfaces 24.
  • the upper narrow sides 4 each have a plurality of projections 6, for example can be formed as knobs.
  • the lower narrow sides 5 have for receiving such projections 6 corresponding recesses 7.
  • These projections 6 and recesses 7 allow mating of several formwork elements 1 to formwork 21, as shown in FIG. 5 is shown schematically. Of course, more than two such formwork elements 1 are usually arranged one above the other.
  • a gap 20 is present between the side plates 2 and 3, which can be filled in a conventional manner with concrete. After curing of the concrete, the side plates 2 and 3 remain as a permanent formwork on the building wall and can be plastered for example in the usual way.
  • the side plates 2 and 3 are each connected to a plurality of stirrups 13 with each other. It is envisaged that the side plates 2 and 3 are connected to each other at the place of use with these stirrups 13. For the transport from the production plant to the place of use, the side plates 2 and 3 can thus be transported adjacent to one another and thus without gap 20.
  • the stirrups 13 are according to FIG. 1 formed substantially U-shaped and have a preferably straight web 14, projecting from the right angles two tabs 15. These tabs 15 each have a tip 19 and laterally projecting hooks 18. About the web 14 and the tabs 15 extends a stiffening rib 16.
  • the stirrups 13 are preferably punched parts made of sheet metal. The web and the two tabs 15 are thus formed strip-shaped. This strip-shaped design in conjunction with the stiffening rib 16 results in a comparatively stable and stiff and connection-rigid plug-in bracket 13. Holes 17 in the web 14, which for example have a diameter of 5 mm, can be used for attaching structural steel.
  • the stirrups 13 are inserted for connecting the side plates 2 and 3 from above or from below in this.
  • For receiving the tabs 15 have the side walls 2 and 3 on the upper narrow side 4 and on the lower narrow side 5 respectively corresponding slots 11.
  • These slots 11 may be tapered inwardly, so that the hooks 18 when inserting the stirrup 13 in the side plates 2 and 3 dig in and thus anchor the corresponding stirrup 13 substantially insoluble.
  • the webs 14 thus have a distance to the upper narrow side 4 and lower narrow side 5.
  • This distance is for example a few mm, for example 10 mm.
  • the so recessed arranged webs 14 thus do not affect the function of the projections 16 and the recesses 7.
  • the projections 6 and corresponding to the recesses 7 are arranged so that they are outside the recesses 12.
  • On the inner sides 9 of the side plates 2 and 3 can dovetailed grooves 10 extend, which serve to secure the concrete.
  • 6 webs 25 may also be arranged between the projections.
  • stirrups 13 are arranged alternately. Between two stirrups 13, which are inserted into the upper narrow side 4, thus there is a stirrup 13, which is inserted into the lower narrow side 5.
  • the preferred arrangement of the stirrups 13 in adjacent formwork elements 1 and 1 ' shows the FIG. 5 ,
  • a formwork 21 can be made entirely from a plurality of said formwork elements 1. Also conceivable is an embodiment in which according to FIG. 5 the formwork 21 also has a further formwork element 22 which in a known manner firmly foamed connecting webs 23 and thereby can withstand a particularly high concrete pressure. Preferably, such a formwork element 22 is arranged in a lower region of the formwork 21. Of course, several such formwork elements 22 may be provided.
