Definitions

  • the present invention relates to a device for anchoring a building construction on a load-bearing ground with a support member for introducing tensile and / or compressive forces of the building construction in the ground and on a generic method for anchoring a building structure.
  • Such devices are known to be used in civil engineering for pile foundations to initiate the resulting from a surface area of the ground on the support member from the superstructure burdens in deeper subsoil layers (see, eg, the document DE-A1-102005019168 ).
  • These loads include, in particular tensile and / or compressive forces, which are merged starting from the building construction on a head side of the support member, to which the building structure is anchored to the support member, and are removed from there along the longitudinal extent of the support member in the depths of the ground .
  • support members are used, for example, anchor or nails, which are usually loaded on train, or piles, which are charged to train or pressure or both.
  • the subsoil may be, for example, the ground or a tunnel wall.
  • so-called self-drilling anchors are known in which the support member is designed as an operational drill with a continuous axial cavity.
  • the hardenable medium can already be injected into the subterranean hole during drilling, and the support member is in an already operational condition after completion of the drilling operation and hardening of the medium.
  • the support member is made of a drillable material.
  • a conventional self-drilling anchor is therefore essentially formed by a steel cylinder.
  • such a material has considerable constructive disadvantages, in particular with regard to weak electrical insulation effect and low corrosion protection.
  • the present invention seeks to provide a device and a method of the type mentioned, in which while avoiding the aforementioned disadvantages, the simplest possible installation of the anchoring device in compliance with building requirements, especially in corrosion prone and / or electrically stressed environment is possible.
  • the device has an envelope profile with a longitudinal channel in which the support member is anortbar, so that an inner annular space between the envelope profile and the support member is present.
  • the envelope profile can be used to make a hole in the ground and has an opening at the hollow sole side end, so that a hardenable medium can be driven through the longitudinal channel into an outer annular space between the hole and the envelope profile. Due to the hardenable medium, a connection with the enveloping profile and the support member can be produced in the inner annular space.
  • Such an anchoring device can meet high constructional requirements, in particular by a suitable choice of a support member with appropriate construction and / or material properties. It is especially to think of materials with good corrosion resistance and / or low electrical Conductivity, which nevertheless have a sufficient capacity.
  • the structural complexity for installing the anchoring device can be kept low, since according to the invention a suitably chosen enveloping profile with appropriate construction and / or material properties can be used to produce the foundation hole. To think is particularly on impact and / or drilling resistant materials. Since the enveloping profile as part of the anchoring device preferably remains in the ground, eliminates at least a complex removal of a corresponding drilling device from the ground.
  • the inventive device makes it possible that the load capacity of the support member with respect to the tensile and / or compressive forces acting thereon by any susceptibility to corrosion of the Hüllprofils undergoes little or no impairment. Because the support member may have in this case by the curable medium within and outside the Hüllprofils a sufficient bond with the ground. Also, a possible influence of any electrical conductivity of the envelope profile can be avoided in the inventive device, in particular by the building structure is anchored substantially only to the support member and thus only negligible conductor properties can occur on the Hüllprofil.
  • the method according to the invention preferably also comprises the step of connecting the building construction to a head side of the support member, which protrudes from the enveloping profile.
  • the support member is formed substantially rod-shaped. More preferably, the support member along its longitudinal extent to a substantially constant thickness. Most preferably, the support member on the envelope of a circular cylinder and / or is formed substantially circular cylindrical.

  • the longitudinal channel corresponds to the interior of the cladding tube.
  • the inner annulus corresponds to the space between the cladding tube and the support member and the outer annulus the space between the cladding tube and the hole in the ground. It is also conceivable, for example, an 8-shaped profile, in which two support members are used, which are separated by the intermediate wall of the 8-shaped profile.
  • the envelope profile is formed by a laterally open profile.
  • it may be an H-shaped profile, in which two support members are used, which are separated by the intermediate wall of the H-profile.
  • the longitudinal channel corresponds to the space that is surrounded by the non-open sides of the Hüllprofils.
  • the inner annulus corresponds to the gap between the non-open sides of the envelope profile and the support member.
  • the outer annulus corresponds to the space between the non-open sides of the Hüllprofils and the hole in the ground.
  • the longitudinal channel in the envelope profile is preferably formed according to the geometry of the support member. Accordingly, the inner annulus preferably has a substantially constant thickness along its longitudinal extent and / or along its circumference.

  • the support member has an uneven surface structure, in particular at the surface region, which is opposite to the inner wall of the enveloping profile in the longitudinal channel. That's what you can do provided the positive connection with the curable medium or increased.
  • a thread-shaped surface structure along the lateral surface of the support member is arranged.
  • the inner wall of the Hüllprofils along the longitudinal channel may be formed substantially smooth or also have an uneven surface structure, in particular in a thread form to provide a corresponding positive connection with the curable medium or increase.

  • the placing of the support member takes place in the enveloping profile such that the support member is at one end substantially flush with the Lohlsohlen solutionen end of the Hüllprofils or protrudes from the Lohlsohlen districten end of the Hüllprofils.
  • an attachment may be arranged at the hollow sole side end of the enveloping profile, into which the support member protrudes. As a result, essentially the complete depth of the hole, within which the envelope profile extends, can be used to dissipate the force into the ground.
  • the support member does not extend completely to the Lohlsohlen solution end of the Hüllprofils, wherein a Lohlsohlen generaler area of the Hüllprofils is filled, for example, only by the curable medium or an essay is arranged on the Lohlsohlen currenten end of the Hüllprofils, which projects into the longitudinal channel and at which the support member abuts.
