Definitions

  • the invention relates to a cantilever slab and / or joint element for reinforced building structures, consisting of a one-part or multi-part structure designed to accommodate tension and / or pressure reinforcement elements, as well as transverse force rods inserted or usable in this structure, and / or pressure reinforcement elements in the building structure are formed approximately transversely to a vertical longitudinal center plane of the same, and the transverse force bars have a central section that extends obliquely to the horizontal, and a region of the sections of the transverse force bars projecting on both sides of the building body are parallel to the central axis of the through openings for the receptacle the tension and / or compression reinforcement elements is aligned.
  • thermal bridges In the area of such thermal bridges, there has been an increasing trend in recent years to use insulation elements in a way to thermally separate the above structures from the internal structures.
  • pins for the upper and lower reinforcement are concreted into the ceiling slab on the mutual connection sides, which then protrude sufficiently to insert into the cantilever slab, e.g. a balcony slab to be able to intervene.
  • the tensile and compressive forces can be easily transmitted.
  • strips made of a heat- and sound-insulating material are used to produce a corresponding heat insulation and these structures are separated from one another, the static problem arises that special measures for the transmission of the transverse forces are necessary. If the continuous transition between the two plates is interrupted by the insulating material, the transverse forces have to be transferred via special reinforcement inserts.
  • Such shear bars are formed in a known embodiment (CH-PS 677 249) from a peg iron, which is concreted in with one of its parallel end parts near the upper surface of a ceiling slab, then connecting a central part, which runs obliquely from top to bottom, and wherein the second parallel end part of the peg iron can be embedded in the cantilever plate near its lower surface.
  • reinforcement elements practically formed in one piece, which both the tensile and compressive forces as well to transfer the transverse forces between a cantilever slab and the ceiling slab connected to it.
  • two belts arranged parallel to one another at a distance are provided, the plug-in iron forming the transverse force rod being rigidly welded to the respective ends with both belts.
  • connection reinforcement that is stable in itself in the area of cantilever slab and / or joint elements, but then there are no possibilities for using continuous reinforcement elements. So you can still only work with the appropriate spikes.
  • slabs of heat-insulating foam are provided.
  • the reinforcement is composed of a tensile reinforcement bar, a pressure reinforcement bar and a shear reinforcement and all of these reinforcement parts lie in one plane.
  • the two ends of the shear reinforcement are firmly connected to the respective tension or compression rod, for example by welding or wire binding.
  • the individual reinforcement elements and also the shear reinforcement are cast or glued into the heat-insulating plate.
  • it is only a question of providing an intermediate element between the two thermally separable plate parts of a ceiling structure, without the possibility of being able to use continuous tensile or compressive reinforcements.
  • the transverse force bars are not in a specific position relative to the tensile and compressive reinforcement elements, as is the case, for example, in DE-A-43 00 181 and DE-A-43 02 683 can be seen.
  • the present invention has therefore set itself the task of designing the shear force rods in a cantilever plate and / or joint element of the type mentioned in such a way that an optimal transmission of the shear forces is made possible.
  • this is achieved in that at least one essentially straight region of the sections of the transverse force bars projecting on both sides of the structure lie at least approximately in a horizontally extending plane through the central axes of the through openings provided for receiving the tension and / or compression reinforcement elements .
  • the tension and compression reinforcement elements used when laying the reinforcement elements and the corresponding areas of the shear bars lie in one plane, so that reinforcement bars to be laid transversely above them a mutual fastening of the tension and compression reinforcement elements and the Enable shear bars in a simple way.
  • the connection can be made here, for example, by wires.
  • the transverse force rod lies exactly in the tensile and compressive axis, so that a significantly better force transmission, which is particularly important due to the interruption of the continuous construction by the cantilever plate and / or joint element, is ensured.
  • the length of the straight areas of the sections of the transverse force rods projecting beyond the structure on both sides is a multiple of the thickness of the structure in the axial direction of the through openings. Practically seen in the axial direction, there is a short, sloping central section, and then relatively long, straight areas adjoin this, which lie in the plane of the tensile reinforcement elements or the pressure reinforcement elements.
  • the angle of inclination of the central section of the transverse force rods to the straight regions is substantially greater than the acute angle enclosed between the end regions and the straight regions of the transverse force rods.
  • the special angle of inclination between the central section and the straight areas ensures that the bent area between these sections is already embedded in the concrete, the inclined central section still being relatively steep and even for the concentrated transmission of the transverse forces.
  • the straight end region encloses a corresponding acute angle with the straight region to ensure that a correspondingly large bending radius and thus a simpler manufacture of the shear bars is possible, and that the free end does not have the corresponding plane of the tensile reinforcement elements or the pressure reinforcement elements protrudes.
  • a particularly favorable force profile is achieved if a shear force rod is inserted between two through openings as seen in the longitudinal extent of the structure. As a result, there are practically always alternating shear bars and through openings for receiving the tension and compression reinforcement elements.
  • a structure 1 is provided, which is made of a heat-insulating foam or another heat-insulating or sound-insulating material.
  • the structure 1 serves to accommodate tension and / or compression reinforcement elements which can be inserted into through openings 2.
  • tubular bodies 3 are used in the area of the through openings, which are made of plastic, for example. Through these tubular bodies 3 and through openings 2 formed by them, the reinforcement elements passing through a ceiling slab and the adjoining cantilevered slab area can be inserted in the tensile and pressure areas. This means there are no interruptions in the reinforcement.
  • transverse force rods 4 are used in the cantilever plate element, which have a central section 5 that runs obliquely to the horizontal and each area 6, 7 that runs straight on both sides of the building body 1. These areas 6, 7 run axially parallel to the central axis 8, 9 of the through openings 2 or the corresponding tubular body 3.
  • the structural body 1 consists of several partial bodies 10, these partial bodies being shown in FIGS. 3 and 4.
  • the transverse force rods 4 are inserted with their obliquely extending central section 5 into a groove 11 formed on a lateral edge boundary of a partial body 10, the open area of the groove 11 is closed accordingly by moving the next partial body 10.
  • the inserted shear bar is held captive.
  • the mutual connection between the partial bodies 10 takes place by means of tongues 12 and grooves 13 formed on their lateral edge boundaries, this tongue and groove connection also being made possible by direct attachment, especially since the undercut areas are selected to a certain extent by the choice of the material of the partial bodies 10 Area are elastic. So that a correspondingly stable mounting and alignment of the partial bodies 10 is ensured, they have grooves 14, 15 on both sides of their upper and / or lower edge region, a corresponding U-shaped holding rail 16 being able to be plugged on or pushed on.
  • the tubular body 3 For receiving the tubular body 3 10 through openings 2 are present in each case approximately in the middle of the partial body.
  • the tubular body 3 has a plurality of circumferential ribs 17 which are arranged at a distance from one another, so that the tubular body 3 does not come to bear over the entire surface of the inner wall of the through openings 2.
  • a relatively easy insertion of the tubular body 3 into the through-openings 2 is thereby possible, wherein the ribs 17 can nevertheless be used for a corresponding mounting without additional gluing or the like.
  • a stop rib 18 is provided which has a larger diameter than the ribs 17.
  • One or more additional ribs 19 are provided on the ends of the tubular body 3 projecting beyond the structure 1 on both sides, which serve for a correspondingly good locking in the filled concrete. If it is also required that the tensile or pressure reinforcement elements inserted into the tubular body 3 are completely enclosed with concrete, then there is a need for the escape of excess air bubbles in the area of the tubular body 3. For this purpose, for example, one or more holes 20 are provided, via which the air bubbles can escape into the annular space between two ribs 17.
  • the present invention is essentially about the special design and arrangement of the transverse force bars 4 in the structure 1 or with respect to the central axes 8 of the through openings 2 or the tubular body 3.
  • the structural measures provided for this purpose are explained in more detail below:
  • each shear force rod 4 protruding on both sides of the structure 1 has a region 6 which is aligned axially parallel to the central axis 8 of the through-openings 2 for receiving the tension and / or compression reinforcement elements.
  • the straight areas 6, 7 on both sides of the structure 1 are at least approximately in horizontal planes 21, 22, which are intended by the central axes 8, 9.
  • the tension and pressure reinforcement elements are also located in these planes 21 and 22, which through the tubular body 3 be introduced. This results in a power transmission that runs exactly in the tension and compression axis.
  • the length L of the straight areas 6, 7 is a multiple of the thickness D of the structure 1 seen in the axial direction of the through openings 2.
  • the straight regions 6, 7 of the transverse force bars 4 merge into an arc region 25, 26, a straight end region 27, 28 in turn adjoining this arc region 25, 26.
  • the straight end region 27, 28 forms an acute angle ⁇ with the straight region 6, 7.
  • a corresponding vertical distance A between the two straight regions 6, 7 is specified, it being sensible to choose the radius of the bends 23 and 24 and 25 and 26 to be the same size. This is of particular advantage for manufacturing reasons, with particular attention also having to be paid to the material properties of the transverse force rod.
  • the angle of inclination ⁇ of the central section 5 is also substantially larger than the acute angle ⁇ enclosed between the end regions 27, 28 and the straight regions 6, 7.
  • the structural measure is additionally achieved or provided for optimization that the directly free end 30, 31 of the straight end regions 27, 28 in the region of the corresponding plane 21, 22, which is intended by the central axes 8, 9 of the through openings 2 lies.
  • the transverse force bars are shown twice as full and cut off twice at their point of emergence from the building structure 1. It can be clearly seen here that, seen in the longitudinal extent of the structure 1, a transverse force rod 4 is inserted between two through openings 2 or corresponding tubular bodies 3 lying one above the other in the vertical direction. Since the corresponding straight regions 6 and 7 also come to lie in the levels 21 and 22, the pressure reinforcement elements or tension reinforcement elements introduced through the through openings 2 or the tubular body 3 can be mutually connected with correspondingly laid reinforcement bars, for example by wrapping it with a wire.
