Definitions

  • the invention relates to a reinforcement device for connecting two concrete components and for bridging a joint between the two concrete components with the features according to the preamble of claim 1.
  • a reinforcement device which comprises a number of continuous reinforcing bars for connecting the concrete components.
  • Known embodiments of such reinforcement devices provide that the reinforcing bars have an angled push section in the joint area.
  • the angular arrangement of the thrust section allows the targeted absorption of transverse or shear forces.
  • DE 37 44 016 C2 discloses a reinforcement device for connecting two concrete components, are arranged in the reinforcing rods in the longitudinal direction for receiving bending forces. Further, centrally arranged reinforcing bars have a vertically angled thrust portion, by means of which lateral forces can be absorbed in the direction of gravity. The arrangement is push-soft in the horizontal direction. There are complex additional measures for receiving horizontal, lying in the joint plane shear forces to meet.
  • a reinforcement device which comprises in addition to the angled, provided with a pushing section reinforcing bars further reinforcing bars.
  • additional reinforcing bars lie horizontally in the plane of a base plate and span the dividing line in an X-shape. The arrangement of these additional reinforcing bars in ⁇ 45 ° direction allows the absorption of horizontal shear forces.
  • the invention has for its object to provide a reinforcement device for connecting two concrete components, which allows a simplified transmission of reliable power transmission in the region of the joint while maintaining the sound insulation.
  • the reinforcing rods are provided with an angled thrust section.
  • An axis component projected into the plane of the joint of the longitudinal axis of the push section lies at an angle to the vertical direction and to the lateral direction of the joint plane.
  • the projected axis component is advantageously at an angle in a range of including 10 ° and incl. 20 ° to the vertical direction, wherein the angle is in particular about 15 °. This results in a multiple oblique position of the thrust section in the spatial direction.
  • the thrust section is obliquely inclined in a plane from the vertical direction and the longitudinal direction, ie transversely to the joint plane.
  • the skew component in this plane allows effective transverse or thrust force in geodetic height direction, as it arises by weight load.
  • the thrust sections of the same reinforcing bars with an axis component are inclined at an angle in the joint plane. Without additional reinforcing measures, a horizontal bracing in the transverse direction can also be effected at the same time for receiving corresponding transverse loads.
  • the reinforcing rods are arranged with their thrust sections in angles with alternating signs.
  • an arrangement is expedient in which the angles of the thrust sections alternately have at least approximately the same amount with changing sign. It causes a symmetrical force application. Vertical and horizontal loads are decoupled. A vertical weight load does not cause a horizontal shift. With low material and labor input can an effective power transmission between the two concrete components are produced. The overall low required material cross section of the reinforcing bars contributes to a good impact sound decoupling.
  • a holding device for angular fixation of the thrust sections for use in the joint is provided.
  • the holding device is formed by a particular trained as a footfall sound insulation element.
  • the holding element causes in multiple function an effective sound-insulating bridging or filling of the joint and at the same time a positional fixation of the reinforcing bars in the non-cast state.
  • the holding device or the insulating element can be used as a lost formwork.
  • the prepared reinforcement device comprising the holding device or the insulating element and the reinforcing bars can be used without further elaborate alignment and fixing in the intended formwork and cast directly.
  • the holding device is formed flat and has in its plane at an angle to the vertical direction lying slots for receiving the thrust sections.
  • the flat design allows the filling of the joint as a lost formwork.
  • the angular arrangement of the slots leads from a production point of view to a simple manufacturability. For assembly, only a threading of the bent reinforcing bars is to make, with their thrust section held without readjustment by means of the angled slots exactly in the intended angular position become. Elaborate alignment operations can be dispensed with.
  • the holding device is advantageously designed in the form of a hollow material comprising an insulating material, made of sheet metal and / or plastic with two opposite side walls, wherein the slots are arranged in the side walls.
  • the hollow metal box leads with low total weight to a high mechanical strength.
  • the two mutually spaced side walls each have slots for guiding the thrust sections.
  • the thrust sections carried out are guided or held in both sidewall planes. This results in a reliable spatial fixation.
  • At least one spacer is arranged in particular as a thrust bearing, which is in particular formed of a sound-absorbing material which is able to transmit compressive forces.
  • a thrust bearing which is in particular formed of a sound-absorbing material which is able to transmit compressive forces.
  • Even with a thin, lightweight version of the side walls results in a high load capacity across their plane. For example, a buckling of the side walls and a concomitant damage to the internal insulating material is reliably avoided during the casting process.
  • the sound-absorbing material of the thrust bearing contributes to the exclusion of the formation of unwanted sound bridges.
  • sealing elements are provided for sealing remaining openings in the box. After mounting the reinforcing bars in the box can openings for example, remain on the oversized slots or lateral faces. By means of the sealing elements, penetration of concrete into the interior of the box is avoided. At the same time, the sealing elements can also serve for fixing the position of the reinforcing bars in the slots of the box.
