Definitions

  • the invention relates to a pouring dowel for mutual tensile connection two solid bodies in a concrete-concrete composite.
  • the pouring dowel with its fastening part is over one Temporary flowable, hardenable fasteners such as reactive resin mortar in one Blind hole can be fastened in the first solid like old concrete and with its radially projecting Embedding part in this, later hardening, second solid like new concrete flowable embeddable.
  • Temporary flowable, hardenable fasteners such as reactive resin mortar in one Blind hole can be fastened in the first solid like old concrete and with its radially projecting Embedding part in this, later hardening, second solid like new concrete flowable embeddable.
  • dowels As dowels, angled or conical ends are usually used on site upset, prefabricated reinforcing bars and on-site with threaded rods combined thread plates used. These dowels are regarding Pull-out strength of the embedding part from the new concrete or The introduction of tensile force in these and the tensile rigidity are not optimal.
  • the conical cap forms at an axial half angle of 15 ° along its axial Length a double radial cant. This cone cap is not for force application optimized but serves as a blind form that can be easily removed axially from the new concrete surface.
  • threaded sleeves made of plastic are distributed over the entire circumference Taper ribs with an axial half angle of 45 ° and double radial elevation along their axial length embedded in new concrete. In plastic threaded sleeves are only low tensile forces can be introduced.
  • corrugated pipe sections are embedded in new concrete combined with other components via thread.
  • the object of the invention is the technologically simple implementation of a Socket anchor with geometry optimized with regard to the introduction of tensile force and tensile rigidity.
  • a cast-in dowel with a temporary flowable hardenable fastening means can be fastened in a blind hole in the first solid, Fastening part and with a radially projecting, in a later hardening second solid body can be embedded in a fluid manner, embedding part within the embedding part a conical sleeve.
  • the axial half angle of the conical sleeve is advantageously in the range of 20 ° up to 40 °, in the simulated ideal case at 30 °, which leads to an optimal introduction of tractive force into the Material concrete leads.
  • the end ratio of the diameters over the axial length is advantageous the conical sleeve certain radial cant in the range of 2.5 to 5, which makes the axial tensile stress introduced via the fastening part of the cast-in dowel completely in a compressive stress of the normally oriented cone area can be transformed, without locally exceeding permissible compressive strength limits.
  • the conical sleeve is advantageously hollow with essentially the same wall thickness, making them technologically high through stamping and forming processes simple and therefore inexpensive, further advantageous from iron sheet or iron pipe ends from a few mm wall thickness.
  • the conical sleeve is advantageous as a separate component for the integral connection Welding or for the axially positive connection by screwing or Rotary snap-in by means of a special remaining cast-in dowel as assigned Interface and / or guide formed special axial opening on the smaller Base area prepared, which makes a simple corresponding to the requirement Combination of system components on site is possible.
  • the special axial opening of the conical sleeve is advantageous for the connection to one axial area of the rest of the cast-in dowel, which protrudes axially of the remaining pouring dowel beyond the larger surface area of the conical sleeve, which means that when the sprue plug is driven into the blind hole, the blows do not directly on the cone sleeve and can thus damage it beforehand.
  • the conical sleeve is prefabricated in one piece with the rest Molded dowels designed, whereby predetermined breaking points limiting the introduction of force cohesive or form-fitting connection points, which by the site Combination of a separate cone sleeve with the rest of the pouring dowel may occur can be avoided.
  • the conical sleeve as a radially widened end section is advantageous as a cast-in dowel executed pipe section executed, whereby a smooth force deflection in the Pipe wall without notches limiting the introduction of force is possible.
  • a cast-in dowel 1 with a temporarily flowable, curable, as a reaction resin mortar, fastener 2 in a blind hole 3 in the first solid body 4, designed as old concrete, can be fastened, fastening part 5 and with a radially projecting, later hardening, as new concrete executed, second solid 6 flowable embedding, embedding part 7 within the Embedding part 7, which is hollow with essentially the same wall thickness, conical sleeve 8 with an axial half angle ⁇ of 30 °.
  • the Cone sleeve 8 is filled on the inside with the second solid 6.
  • the one as the end Ratio of the diameters D, D 'over the axial length L of the conical sleeve 8, radial cant is about 3.5.
  • the cone sleeve 8 is a radially widened End section of a pipe section with alternately alternating bulges 9 integrally formed with the rest of the pouring dowel 1.
  • the conical sleeve 8 which is designed as a separate component, is engaged by rotating it one, the special remaining one, as a pipe section with alternating alternations Bulges 9 designed, casting dowels 1 assigned, designed as a catch, special axial opening 10 on the smaller base for axially positive Fastening and guidance prepared, with the rest of the pouring dowel when connecting 1 protrudes axially by the distance A over the larger top surface of the conical sleeve 8.
