Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • the anchor rod is made of a fiber reinforced plastic tube containing both longitudinally and helically wound fibers.
  • the plastic tube has a thread at both ends.
  • a drill bit on the other thread a sleeve is screwed in half.
  • a threaded pin of a drill is screwed.
  • the drilling process is started.
  • another anchor rod can be screwed instead of the threaded pin in the sleeve and the drilling process can be continued.
  • injection material is pressed through the tubular anchor rod into the hole.
  • an anchor plate is pushed over the protruding end of the anchor tube and a nut screwed onto the thread and tightened against the anchor plate.
  • GRP threaded rods Commercially glass fiber reinforced plastic threaded rods (GRP threaded rods) of the company H. Weidmann AG, Rapperswil, are available, which have a full cross-section and have a trained over the entire length of the rod thread. Hexagonal nuts for these threaded rods are also commercially available. These nuts are made of plastic or steel. The threads are designed as coarse threads. Coarse threads have a relatively large clearance between the screw and the nut.
  • These coarse threads have with respect to the thread longitudinal direction curved threaded surfaces and obtuse flank angles of up to 140 or 150 degrees. They have the advantage that the fiber structure of the threaded rod can follow the thread profile and therefore can be formed continuously. The power transmission from the thread to long, un maybetrte fibers happens very directly. Therefore, large forces can be transmitted via the coarse thread on the threaded rod.
  • Standard threads have simply curved threaded surfaces and sharp flank angles of 60 degrees or less. Standard threads are virtually slip-free thanks to their high precision and sharp flank angle.
  • Coarse threads have the disadvantage over standard threads that they have a relatively large slip, i. have a relatively large displacement of the rod relative to a nut or a threaded sleeve. This slip occurs as a result of tensile or compressive forces acting parallel to the longitudinal axis of the thread and the rod. This slippage restricts the use of threaded rods made of fiber reinforced plastic with a coarse thread.
  • FRP FRP
  • GRP rods tensile strength at the same time low thermal conductivity and also their corrosion resistance
  • a central problem in building construction is the reliability of connecting FRP threaded rods.
  • FRP bars A major obstacle to the use of FRP bars in building construction, and in particular for the application in thermal insulation layers bridging components, is also their low modulus of elasticity, or their compared to structural steel much higher elasticity.
  • a fastener which serves to attach loads to a thermal insulation having building wall.
  • This fastener has an elongated insulating stainless steel, plastic (eg recycled polyurethane), glass fiber or carbon fiber reinforced plastic, wood or a combination thereof.
  • the fastener has a mounting end to be attached to a building wall and a load end to which a load is attachable. At the load end, an internal thread for attachment of a load attachment means is provided.
  • a threaded sleeve is glued to both ends of the insulating, which threaded sleeves have internal thread.
  • pressure and shear forces should also be able to be transmitted through the thermal insulation.
  • a device is known from DE-A 199 47 913 known.
  • This device has at least one rod made of fiber-reinforced plastic. This serves to transfer load through a thermal barrier coating.
  • both ends of the rod each extend into a first end of a threaded sleeve, which end forms a first load engagement means.
  • a gap between the threaded sleeve and the rod is at least partially filled with a cured filler and adhesive.
  • a second load application means for receiving forces to be transmitted to the rod is formed.
  • a thermal barrier coating is part of the device.
  • the rod is formed by a threaded rod with an external thread which extends through the thermal barrier coating.
  • the threaded sleeves have, as the first load application means, an internal thread accessible from the first end of the threaded sleeve and corresponding to the external thread of the threaded rod.
  • a threaded sleeve is screwed onto the threaded rod along a common longitudinal axis.
  • the thermal barrier coating advantageously consists of high-quality thermal insulation, in particular vacuum thermal insulation panels whose lambda value is between 0.004 and 0.020 W / mK.
  • This material allows insulation thicknesses of 1.5 to 2 cm to be provided while exceeding the insulating properties of conventional insulation materials with an insulation thickness of 8 to 15 cm.
  • improved thermal insulation can be achieved.
  • the elasticity of the tension element is of considerably less importance than with conventional, larger layer thicknesses.
  • two or more threaded rods are arranged as parallel tension bars next to each other.
  • all threaded rods penetrate the same vacuum insulation board or the same panel of several vacuum insulation boards.
  • a panel of several thermal insulation panels advantageously has rectangular vacuum plates between the FRP rods, and in an area around the FRP rods penetrated by the FRP rods, spacers and pressure hulls, high density foam panels with recesses for the penetrations.
  • the space between the threaded rod and threaded sleeve is at least partially and advantageously completely filled with a cured filler and adhesive.
  • This filler and adhesive prevents unwanted loosening of the threaded sleeve from a designated position. It also hinders a displacement of the threaded rod in the threaded sleeve along the longitudinal axis and therefore reduces or prevents slippage.
  • the external thread of the threaded rod and the internal thread of the threaded sleeve are engaged. This allows the threaded sleeve to bias against the threaded rod before the filler and adhesive has cured.
  • the threaded rod and the threaded sleeve are advantageously biased against each other. Because so is the slip already before the load situation occurred and the threaded rod and the threaded sleeve are fixed in a position against each other, in which under load virtually no further slip occurs.
  • the gap can be filled as quickly and completely with the filling and adhesive, is advantageously formed in the longitudinal direction of the thread in the threaded rod and / or in the threaded sleeve, a preferably rectilinear channel.
  • the channel connects at least one handling of the coiled space with an outside space outside the threaded sleeve.
  • it connects all the turns of the coiled space with each other and with an outside space outside the threaded sleeve.
  • the internal thread is only a first load application means, and there is on the threaded sleeve before a second load engagement means, which is accessible from the second end of the threaded sleeve forth
  • This may be an external thread or an internal thread whose Axle is parallel to the longitudinal axis. It can also be a hook or an eyelet.
  • a reinforcing bar for reinforced concrete is connected or connectable to the second load application means, which rod consists of structural steel or stainless steel.
  • the reinforcing rod On the reinforcing rod is purposefully designed a head with a standard thread The head may be compressed. This allows the formation of a normal thread with a diameter greater than the diameter of the reinforcing bar.
  • the external thread of the FRP threaded rod is formed as a coarse thread.
  • coarse threads are the fibers of the threaded rod, which are present in the interior of the thread crest, following a wavy line in both adjacent areas of the thread crest and in the region of the thread root in between.
  • the inventive device has the advantage that the two threaded sleeves can be arranged at a distance from each other.
  • the threaded rod made of fiber-reinforced plastic connecting the threaded sleeves over this distance has a significantly lower thermal conductivity than structural steel or stainless steel and essentially forms the only statically necessary thermal bridge. This allows an arrangement of an insulating layer in the area between the threaded sleeves and thus a statically reliable and thermally optimal connection of tensile forces, compressive forces, shear forces or combinations of these forces through the thermal insulation through.
  • the female thread forms a first load engagement means and there is a second load engagement means on both threaded sleeves.
  • the second load application means is expediently accessible from the second end of the threaded sleeve forth.
  • the first ends of the threaded sleeves are advantageously arranged at a distance from each other, which is in a range of 15 to 40 mm, preferably in a range of 20 to 35 mm.
  • the elastic deformation of the fiber composite material already begins to play a decisive role in many construction applications.
  • these areas already allow, with high-quality thermal insulation such. Vacuum thermal insulation elements to achieve excellent thermal insulation between the threaded sleeves and the components in which the threaded sleeves are present.
  • two parallel plates between the two first ends of the threaded sleeves available.
  • the first ends of the threaded sleeves are in abutment with the facing away from each other surfaces of the two plates.

  • the spacing agent is advantageously a fiber-reinforced plastic body.
  • the spacer means advantageously maintains a bias between the threaded sleeves.
  • a transverse force rod is arranged at a distance from the longitudinal axis of the threaded rod, which penetrates the plates and is anchored in the plates.
  • Such a device can serve as a cantilever connection element.
  • the threaded sleeves are connected to the tensile reinforcements of two, mutually thermally separated, concrete slabs and transfer the forces occurring in the tensile reinforcement of the concrete slabs on the threaded rod. With the plates, forces acting transversely to the longitudinal axis can be absorbed and directed from the bottom of the cross-section of the concrete slabs to the top of the concrete slabs to be transferred from one to the other concrete slab with the FRP rods.
  • a pressure body between the plates.
  • This pressure body transfers pressure forces from one to the other concrete slab. Thanks to the distance to the tensile forces transmitted threaded rod moments can be added to the pressure body and / or the pressure forces receiving FRP rod and the tensile forces receiving threaded rod, which allows the connection of a cantilevered component to a supporting component
  • the pressure body can be arranged around the transverse force rod. It is advantageously a fiber-reinforced plastic part whose fiber direction is directed substantially perpendicular to the plates.
  • the transverse force rod may e.g. a threaded rod, which is identical to the tensile forces receiving threaded rod.
  • glass fibers for fiber reinforcement of the plastic are preferred both in the tensile forces receiving threaded rod, in the transverse force rod, in the spacer and in the pressure body, because the glass fiber reinforced plastics (GRP) are available inexpensively and poor heat conductors.
  • a bias When connecting the threaded sleeve with the threaded rod is advantageously created between the threaded rod and the threaded sleeve, a bias, and this bias, at least until the filler and adhesive is cured, maintained.
  • the threaded rod and the threaded sleeve are fixed after the occurrence of the slip produced by the bias in this position against each other. This reduces the later in the load case occurring slip to virtually zero.
  • the bias is created in the later expected load direction.
  • the channel is formed by cutting, in particular milling a recess in the threaded rod parallel to a longitudinal axis of the threaded rod.
  • the incision is advantageously cut or milled into the material at the thread root of the threaded rod or the threaded sleeve.
