Definitions

  • the invention relates to a large-sized formwork element intended for the sheath-concrete construction, in particular made of rigid foam, the side walls of which have a tongue and groove formation on the bearing surfaces for securing the position of staggered formwork elements and are connected to one another by webs and end walls, the end walls corresponding in their design to webs divided in the middle and are provided with an upper and a lower recess which can be closed by insert pieces which can be positively engaged with the end walls.
  • the requirements for the design of the webs and end walls result from their various functions, the particular difficulty being that these requirements partially contradict each other.
  • the webs and end walls should be as strong as possible. It should also be borne in mind that to avoid a large number of differently sized formwork elements, if possible, a single, larger formwork element should be able to be easily and quickly divided in a certain grid dimension, with end walls with upper and lower cutouts which must be created at the separating points close the existing inserts with a secure positive lock that has to absorb the high internal pressure when pouring the concrete.
  • the webs were previously formed on the upper side with upstanding holding ribs.
  • the step-like shoulders were required, on which the insert pieces could come into positive contact and find a hold if they were provided with a central groove matching one of the ribs mentioned.
  • the invention is therefore based on the object to provide a formwork element which combines excellent stability and secure form-fitting hold of the insert pieces with improved processing properties, and to solve this object it is proposed according to the invention that the webs on the top in the middle or even or to the edges are inclined towards the top and the upper insert piece is designed with a flange part, which in the inserted state extends to below the central region of the upper recess of the end wall, on the inside of which flange part.
  • the advantage of the invention is that even without complicated shaping with incisions or the like in the lateral ribs of the webs, i.e. with the simplest shape, no water can collect without this having disadvantageous consequences for the secure holding of the upper insert, because a special flange part is now provided there, which overlaps the inner surface of the end wall. As a result of this flange part, the inner surface of the upper insert is now substantially larger than its outer surface.
  • the inner side surface of the upper insert can preferably be approximately 20% larger than the outer side surface, even if the latter is already considerably larger than each of the side surfaces of the lower insert, e.g. by about 20 to 30%.
  • the upper insert finds further support on projections or springs formed on its upper side, with which it can engage in suitable grooves of a formwork element placed above it, in a preferred embodiment of the invention the upper insert as well as the upper bearing surface of the side walls on its upper side with a continuous circumferential longitudinal spring and transverse springs extending over the entire wall thickness.
  • the webs are preferably approximately 20 to 30% wider than the wall thickness of the side walls.
  • the lower side edges of the webs are chamfered so that the concrete flows around the wide webs better during pouring.
  • a groove or notch extends in the longitudinal direction of the webs in the middle of the flat or laterally inclined surface, which serves as a marking and orientation aid when sawing through a formwork element.
  • reinforcing bars In the case of walls that are heavily loaded by transverse forces, it may be advisable to install reinforcing bars in the concrete on the side opposite the pressure load. If there are ribs on the side of the webs, appropriate recesses for the reinforcing bars can be made in them. On the other hand, if there were no ribs on the webs to prevent water from accumulating, brackets for the reinforcing bars would normally be missing.
  • the formwork elements are preferably made of a rigid foam, e.g. Polystyrene.
  • the invention is not limited to this material. Materials using vermiculite may be mentioned as a further exemplary embodiment.
  • the webs and end walls consist of a non-combustible and / or better sound-absorbing material. For this there is the possibility either to use prefabricated webs and end walls in the manufacture of the side walls in the mold or to provide a positive, releasable connection between the side walls on the one hand and the webs and end walls on the other hand, so that these parts are first manufactured individually and then assembled.
  • lugs 36 on their lateral edges rise above said flat surface, which is denoted by 38 in FIGS. 2 and 3.
  • the lugs 36 go out into ribs 40 which protrude inwards from the inner surface of the side walls 12 and extend from the upper bearing surface to the webs 16.
  • the ribs 40 are undercut and, together with the lugs 36, form depressions 42 into which reinforcing irons can be inserted.
  • the webs 16 are beveled, as shown at 44 and 46, so that they are completely flowed around when the concrete is poured.
  • the central longitudinal plane of the webs 16 is marked by an upper and lower groove 48, which preferably also extends in the same plane over the inner and outer surfaces of the side walls 12.
  • the groove 48 facilitates the precise sawing through of the formwork element in grid dimensions.
  • the cross section of the end walls 14 is equal to the half cross section of the webs 16 formed by division along the groove 48. Therefore, there are two lugs 36 on the top of the end walls 14 on the inner edge, while the top of the webs 16 is provided with four lugs 36.
  • the formwork element 10 shown in FIG. 1 has two parallel side walls 12, two parallel end walls 14 and three webs 16.
  • the end walls 14 and webs 16 each have an upper recess 18 and a lower recess 20 which, as from FIGS. 1 and 3 can be seen to have a substantially rectangular shape with rounded corners. Since the upper cutouts 18 are larger than the lower cutouts 20, the webs and end walls are shifted downward with respect to the average height of the formwork element.
  • the cutouts 18 and 20 in the end walls 14 are either left open to ensure the connection of the concrete to the chambers in the adjacent formwork element, or the cutouts are made using suitable insert pieces 22 or 24 closed.
  • a continuous longitudinal spring with transverse springs arranged at certain grid intervals extends along the upper bearing surface of each side wall 12 and over the upper bearing surface of the insert pieces 22.
  • the latter extend over the entire wall thickness of the side walls 12 and the equally strong insert pieces 22.
  • the wall thickness can e.g. 5 cm.
  • the longitudinal spring on the upper bearing surface is designated by 26 in FIGS. 2 and 3, while the transverse springs are designated by 28.
  • Corresponding longitudinal grooves 30 and transverse grooves 32 are located on the lower bearing surface of the formwork element to match the longitudinal and transverse springs 26, 28, so that transverse forces can be transmitted after the form-fitting stacking of the formwork elements.
  • flat, undercut grooves and / or ribs 34 are formed on the outer surfaces of the side walls 12, end walls 14 and inserts 22, which serve for better plaster adhesion.
  • the webs 16 and end walls 14, as shown in FIGS. 2 and 3, are flat and flat, so that The lower insert 24 is smaller and therefore only needs to absorb lower loads.
  • the upper insert 22 is provided with lateral vertical dovetail-shaped grooves which, in cross-section, match ribs 52 which extend in the vertical direction from the lower bearing surface to the webs 16, are flush with the ribs 40 and are of different lengths match the latter.
  • the ribs 52 which engage in the matching dovetail-shaped or T-grooves of the lower insert 24, this is held by projections 54 molded onto it, which engage behind a lower shoulder on the end walls 14.
  • the lower insert pieces 24 are designed symmetrically such that they can also be inserted inside the recess 20 with the inside out, ie the inside and outside are the same. In the example, the area of these sides is only about two thirds of the inner area of the upper insert 22 with flange part 50.
