Definitions

  • the invention relates to a wall component with mutually spaced concrete shells and the concrete shells connecting, with their ends embedded in the shell concrete bolts.
  • Wall elements of such kind are from the DE 10 2005 041 082 A1 known.
  • the connecting bolts of these known wall components consist of bundles over the length of the bolt endless glass fiber strands, which are embedded in a plastic. At their ends, the bolts are formed asymmetrically with an end surface which is at an angle of 30 ° to 85 ° to the bolt longitudinal axis. While the tensile strength of the connecting bolts is relatively high, they have low compressive and shear strength and are extremely sensitive to retrofitting due to the continuous glass fibers. Also problematic is the so-called. Fiberglass corrosion, which requires a compensation of the bolt surface.
  • the invention has for its object to provide a new improved wall element of the type mentioned, in the flaking and microcracks in the areas mentioned are largely avoided.
  • the wall component according to the invention which achieves this object is characterized in that the bolts each have means for holding at least one of the two ends at a distance from a formwork surface forming the concrete shell in question.
  • said means comprise a relative to the bolt in cross-section reduced spacer pin.
  • the spacer pin is arranged coaxially to the longitudinal axis of the bolt. Its cross-section can be reduced to its free end.
  • the cross section of the bolt also decreases towards the spacer pin.
  • a projection area is created into which only the spacer pin and the tapered bolt end extend, the degree of filling of this projection area being expediently 20 to 30% and the remaining space remaining free.
  • the lateral surface of the decreasing in cross-section bolt kinks in the lateral surface of the spacer pin over.
  • the spacer pin has a length of between 4 mm and 6 mm proved at a bolt diameter of about 16 mm.
  • the pin diameter is suitably between 3 mm and 5 mm.
  • a reduction of the peg diameter can be made eg from 5 mm to 3 mm at the free end.
  • the bolt including said devices consists of polyamide, preferably with an addition of short glass fibers of 30% to 50%.
  • the bolts can remove the weight of the outer shell alone, which additionally contributes to the prevention of cracks and flaking.
  • the bolts are advantageously made in one piece as a casting, in particular injection molded part.
  • the surface is not tempered, as the fiberglass corrosion can not lead to the failure of endless strands, but plays only on near-surface fiber particles.
  • the bolts may have projections, in particular annular projections and / or longitudinal ribs. Annular projections and longitudinal ribs can be used to dampen the sound transmission. On the other hand, annular projections can also serve to seal passage openings for the bolts in a heat insulation.
  • Ring projections also serve as so-called WU collars for sealing in-situ concrete when water is pressed onto the outer shell and for lengthening the flow path when moisture migrates along the bolt.
  • eyelets are provided as projections, which can form the said holding devices, by means of which the bolts can be held in the production of the second shell at a distance from the formwork floor.
  • the eyelets of several bolts can accommodate a steel reinforcing strand.
  • one of the two shells as a support shell, the other is designed as a facing shell, wherein the spacer pin is preferably formed on the embedded in the facing shell end of the bolt.
  • the above-mentioned insulation preferably extends continuously over the entire wall component, with the exception of passage openings for the bolts.
  • An in Fig. 1 shown wall component comprises a support shell 1 and a distance to the support shell 1 spaced attachment shell 2.
  • the front shell 2 is connected on its inside with an insulation 3.
  • Between the insulation 3 and the tray 1 is a layer 4 of in-situ concrete, which reinforces the tray 1.
  • the support shell 1 is connected to the front shell 2 solely by bolts 5, which are embedded with their ends in the concrete of the supporting or facing shell.
  • the total thickness of the wall component is 36 cm, the supporting shell thickness 5 cm, the in-situ concrete layer thickness 12 cm, the facing shell thickness 7 cm and the thickness of the insulation 12 cm.
  • Both the support shell 1 and the facing shell 2 have a steel reinforcement.
  • the bolts 5 are made of polyamide into which short, e.g. only 100 microns to 400 microns long and about 10 microns thick glass fibers are embedded, the glass fiber content is between 30% and 50%.
  • the compressive and shear strength is 200 MPa.
  • a total of 48 bolts 5 are provided in the embodiment shown for connecting the support shell 1 to the facing shell 2.
  • the insulation 3 extends to openings for the bolt 5 continuously over the entire surface of the wall component.
  • a bolt 5 has at its intended for embedding in the facing shell 2 end to the bolt longitudinal axis coaxial spacer pin 6 projecting from a conical end face 7 of the bolt 5 and its length 5 mm and the diameter of 3 mm is.
  • a first annular projection 8 connects, followed at a distance further different width annular projections, of which in Fig. 3 the annular projections 9,10,11,11 ', 12 and 13 are shown.
  • the ring width of the free circumferential surface of the annular projection 11 ' is about 14 mm with a bolt diameter of 16 mm.
  • the surface can be profiled or rough to improve the bonding effect with the base concrete.
  • the annular projection 13 merges into a conical end surface 14 which has a pin corresponding to the spacer pin 6. Between the annular webs project from the bolt 5 in each case as far as the annular webs diametrically opposed longitudinal ribs 15, e.g. eight ribs distributed over the circumference.
  • the annular projections are conical, i. the diameter of the annular projection 8 decreases from 16 to 15 mm and that of the annular projection 9 from 15 to 14 mm.
  • the diameter of the annular projections 10 to 13 is 14 mm.
  • FIG. 2 shows the spacer pin 6, whose diameter is small compared to the total diameter D of the bolt 5, between the bolt end and the shuttering floor 16 for sufficient space 17 to receive aggregate grains 18. A spalling of concrete on the outside of the facing shell 2 is avoided. When sinking the bolts in the still liquid concrete, the thin and elastic spacer pin 6 ensures suitable displacement of aggregate grains to the side.
  • a spacer pin 6a can taper towards the free end and at the other end go kink-free directly into a curved lateral surface 21 of the bolt 5.
  • an eyelet 20 is formed on the bolt 5, which makes it possible to hold the protruding into the facing shell bolt 5 so that between the shuttering floor 16 and a conical Bolzenend constitutional 7a a space 19 remains.
  • the bolts can form a screw base for a dowel.
