Definitions

  • the invention relates to a spacing device for fastening a load to a supporting structure of a building according to the preamble of claim 1.
  • external insulation of the building may include layer thicknesses of up to 30 cm.
  • the external insulation is thus becoming more and more relevant for the operating costs of a building, whereby a maintenance of the function of the insulation in the construction and remodeling of buildings is essential.
  • the insulation can be charged only to a certain extent, usually due to the weight of the object to be arranged.
  • the permissible load on the insulation is exceeded, which can lead to damage or destruction of the insulation.
  • the attachment may be bendable so that opens a tight connection between the outer facade and attachment and a detrimental water entry is made possible in the insulation.
  • the spacer has an anchor bolt and a screwed onto the anchor bolt spacer sleeve, wherein the spacer sleeve has a receiving bore for a fastening screw.
  • the spacer sleeve is axially adjustable relative to the anchor bolt.
  • edge distances of about 5-6 cm must be maintained by a fastener to the front end of the concrete ceiling forehead
  • the height of the concrete ceiling front of, for example, about 18-20 cm severely limits the area for attachment of the fastener.
  • minimum distances of approx. 6 to 9 cm between the fasteners must be observed. An insulation in front of the concrete ceiling makes the installation even more difficult.
  • a fastening means for fastening the spacing device to a supporting structure of a building is arranged so radially spaced from the central longitudinal axis of the spacing device, so that a first, a ground facing investment area is greater than a second, the ground remote from the investment area.
  • the entire contact area of the spacing device to the supporting structure is advantageously created to create a first larger contact area, which absorbs a moment in the direction of weight better and at the same time, for example, by the reduced number of fasteners, the thermal conductivity of the proximal portion, in particular by reduced contact areas or investment areas heat-carrying elements to the structure and / or by a reduced number of heat-conducting elements, reduced.
  • the pull-out force acting on the fastening means is greatly reduced in comparison with a design without contact areas. Furthermore, it is advantageous to the structure acting extraction force and the acting moment advantageous decoupled from the hole pattern of the console.
  • the maximum Auszugswert be increased with respect to the structure, wherein the maximum Auszugswert is a force acting against the supporting structure.
  • the pull-out force is only about 1 to 2 kN. The maximum pull-out value is reduced by reduced edge distances to the edge of the structure towards and spacing from other fasteners.
  • individual fasteners which are arranged with an edge distance of about 5 cm to a front side of a concrete structure to each other, with about 5 kN tensile load.
  • a single fastener which is arranged in concrete, however, for example, with about 10 kN tensile load.
  • the pull-out force can be substantially increased.
  • a single fastener per Beabstandungsvorraum is advantageous.
  • the heat conduction is reduced with a fastener per spacer device compared to a plurality of fastening means.
  • the drilling itself is simplified because the reinforcement of the concrete is located predominantly in the region of a front end of a concrete ceiling front.
  • greater degrees of freedom result with regard to on the execution of the thermal decoupling and the bending stiffness of the spacer.
  • the fastening means is configured such that a central longitudinal axis of the fastening means can be arranged substantially equidistant from two front ends arranged on a front of the structure.
  • the maximum extraction value of the fastening means can be increased, whereby the total load of the spacing device is advantageously increased.
  • the attachment means is disposed in the spacer device and configured to pressurize a distal end of a proximal portion of the spacer device and an insulating section toward the support structure.
  • further abutment areas are created within the spacing device between different elements, in particular the insulating section and the proximal area, which follow the principle of the division into different large contact areas between the supporting structure and the fastening means.
  • the power dissipation to the structure is significantly improved.
  • an insulating portion is used to thermally decouple a proximal portion of the spacer and a distal portion of the spacer.
  • the insulating portion is pressure-loaded such that the insulating portion mechanically couples the distal portion to the proximal portion.
  • the insulating portion both substantially maintain the insulation of the entire building and derived at the distal portion attacking moments without a significant bending of the spacing device to a supporting structure of the building. For example, no interlocking threads, in particular between plastic and steel, have to divert the forces.
  • the bending stiffness achieved in this way ensures that the seal between the outer facade and the spacing device at the distal end of the spacing device and thus also the insulation itself is not damaged.
  • the insulating section is loaded with pressure substantially along a longitudinal axis of the spacer device. This advantageously allows large distances from the structure of the building towards a distal end of the distal section be overcome, in particular thick insulating layers can be penetrated at a low deterioration of the insulation.
  • a first subsection of the insulating section is disposed between a distal end of the proximal section and a proximal end of the distal section.
  • the first subsection can thereby be advantageously acted upon from two sides with a force, whereby two engagement surfaces for the production of a frictional connection are provided transversely to a longitudinal axis of the spacing device.
  • the engagement surfaces serve to receive and transmit tensile and compressive forces caused by a moment acting on a distal end of the spacer device. This increases the flexural rigidity of the entire spacing device while maintaining thermal decoupling.
  • the insulating section has a second subsection for the arrangement between a proximal end of the distal section and the supporting structure.
  • two more surfaces are created for a frictional connection, which is beneficial to the Bending stiffness, the absorption and transmission of tensile and compressive forces and the thermal decoupling effect.
  • the second subsection of the insulating section is arranged between the distal end of the proximal section and a fastening section of the distal section.
  • This development also creates two further friction surfaces for the frictional engagement transversely to the longitudinal axis of the spacing device. Through this formation of friction surfaces, the recording and transmission of tensile and compressive forces can be improved.
