Definitions

  • the invention relates to a cantilever slab and / or joint element for reinforced building structures, consisting of a structure designed to accommodate tensile and / or pressure reinforcement elements and transverse force bars inserted or usable in this structure, the transverse force bars engaging in the central portion of the structure and on both sides have projecting sections of the structure.
  • 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 they 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.
  • a cantilever panel element has also already been proposed (EP-A-0 117 897) in which an insulating body consists of an upper and a lower part, reinforcing elements being insertable on the upper part and pressure elements being insertable on the lower part.
  • the upper and lower parts can be plugged together.
  • the tensile reinforcement elements must be finished on the underside of the upper part be installed and the same applies to the shear bars. Only then can the upper part be inserted into the lower part with corresponding pins or the like. From the outset, a correspondingly firm connection of the tensile reinforcement elements in the corresponding grooves of the upper part is required in order to be able to insert this entire unit from above into the lower part.
  • a certain length is specified in such an embodiment of a cantilever plate element, it being at most conceivable to cut off the parts to be plugged together, but this again leads to an unnecessary expenditure of material.
  • the present invention has for its object to provide a cantilever and / or joint element of the type mentioned, which can be manufactured in a relatively small pitch to the required length and in which a simple mounting of the shear bars can be realized.
  • the structure consists of a plurality of components which follow one another in the longitudinal direction and which adjoin one another with their mutually facing lateral boundary surfaces and can be positively and / or non-positively connected to one another to form the structure, and in that the transverse force bars with their central section can be inserted or inserted into through openings which are enclosed by the mutually facing, lateral boundary surfaces and are formed in a groove-like manner before the components are joined together.
  • the through openings for receiving the central section of the transverse force rods run correspondingly obliquely to the horizontal, in accordance with a course of the same which may be oriented obliquely to the horizontal. Since the through openings for receiving the central sections of the transverse force bars can be produced by appropriately forming a groove on a lateral edge boundary, practically any shape or any course of the through openings can be selected, since the transverse force bars can be inserted transversely to the plane of the lateral boundary surfaces.
  • the through openings enclosed by the adjacent lateral boundary surfaces of the components have different cross-sectional dimensions with respect to their longitudinal extent. It is therefore possible to adapt to the necessary mounting of the transverse force bars and to the necessary injection pressure. It makes sense if the two areas of the through openings near the surface of the finished structure are smaller in cross section than the central area. It is precisely in this way that proper alignment and optimal retention are achieved at the two end regions of the through openings, that is to say where the transverse force rods protrude from the structure.
  • the areas of the through holes with a smaller cross section be dimensioned according to the cross section of the central section of the shear bars or at least one area with an approximately square cross section adapted to the diameter of the shear bars is provided.
  • the area of the through opening with the larger cross section extends only in the direction of the groove formed in the one lateral boundary surface.
  • the opposite boundary surface can also be designed in such a case.
  • the flat boundary surface therefore lies over the entire length of the inserted transverse force rod, whereas, for example, the transverse force rod is only held on the outer end regions of the groove in the regions with the smaller cross section.
  • the components are made of an elastically deformable material insofar as the coupling elements provided with undercuts can be plugged onto one another transversely to the course of the undercuts and snap into their form-fitting position.
  • the nose-like parts formed by the undercuts are elastically deformable, so that there is also the possibility of plugging this tongue-and-groove connection in the longitudinal direction of the structure, with the projecting lugs being elastically pushed back and then snap back in a row. A so-called threading in the longitudinal extent of the groove or the tongue can thereby be avoided.
  • the components have horizontally extending grooves near their upper and / or lower edge, the upper and / or lower end of the Structure a cross-sectionally U-shaped rail is provided, which engage in the grooves on the components with webs formed on their two legs and directed inwards.
  • 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.
  • the construction shown is used in the area of the through-openings tubular body 3, which for example consist of plastic. Through these tubular bodies 3 and the 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 building body 1 consists of several components 10, these components 10 in particular being shown in FIGS. 3 and 4.
  • 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 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.
  • the building body 1 is made of several components 10 which follow one another in the longitudinal direction.
  • the successive components 10 face each other with the lateral boundary surfaces 32, 33 and adjoin one another directly.
  • the Shear force rods 4 are inserted with their central section 5 into through openings enclosed by the mutually facing, lateral boundary surfaces 32, 33, which are formed as a groove 11 before the components are joined together.
  • the groove 11 which finally forms the through opening is designed in accordance with the course of the central section 5 of the transverse force rods 4. If, as is generally the case, the central section 5 of the transverse force rods 4 is oriented obliquely to the horizontal, then the groove 11 also extends at an angle designed accordingly.
  • the through openings 34 enclosed by the adjacent lateral boundary surfaces 32, 33 of the components 10 have different cross-sectional dimensions with respect to their longitudinal extent.
  • the two areas 35, 36 located near the surface of the finished building body 1 are designed to be smaller in cross section than the central area 37. Therefore, the central section 5 of the transverse force rod 4 to be inserted into the groove 11 is kept particularly fixed only in the areas 35 and 36, which is sufficient for proper mounting. As a result, lower forces are required to press or press the central section 5 into the groove 11, and it is therefore very easy to carry out a corresponding manual assembly.
  • the areas 35 and 36 are correspondingly adapted to the cross section of the central section 5 of the transverse force rods 4 or are designed in such a way that the central section 5 is held in a positive and non-positive manner even when it is pushed in in the manner of a corresponding fit.
  • the through openings 34 are formed by the groove 11, which is completely formed on a lateral boundary surface 33 of a component 10.
  • the flat lateral boundary surface 32 of the next component 10 thus only forms the end of the groove 11 in order to thereby create a through opening 34 which is closed in cross section.
  • the first-mentioned constructive variant is, however, much simpler for assembly and manufacturing reasons, since on the one hand the shape for the manufacture of the components is simplified and on the other hand the transverse force bars can be preassembled by being inserted into the groove 11 provided on one side. It is therefore only necessary to push or push on the next component in order to fix the transverse force rod used.
  • the region 37 of the groove 11 with the larger cross section extends only in the direction of the one component 10, so that on the opposite side there is a support acting over the entire length done by the next component.
  • coupling elements can be formed on the lateral boundary surfaces 32, 33 for mutual positive and / or non-positive connection.
  • springs 12 and corresponding grooves 13 are provided.
  • the springs 12 and grooves 13 have undercuts 38, 39 which are designed, for example, in the manner of a dovetail connection. In the specific example - see in particular FIGS.
  • the components 10 are made from an elastically deformable material, for example from an expanded foam or another heat-insulating material. Components made of such materials are elastically deformable within certain limits. In the case of the components provided here, the elastic deformability goes just as far as the coupling elements provided with undercuts 38, 39 can be plugged onto one another transversely to the course of these springs 12 and grooves 13 or the undercuts 38, 39, the then formed by the undercuts 38, 39 Can snap noses into their positive position.
  • each boundary surface 32, 33 of the components 10 instead of only one tongue 12 and a groove 13, it also being possible to provide both springs and springs on each boundary surface 32, 33 also provide grooves.
  • the components 10 can have horizontally extending grooves 14, 15 near their upper and / or lower edge.
  • a rail 16 with a U-shaped cross section can then be provided as the upper and / or lower end of the structural body 1, which rail 43, 44 has inwardly directed webs 43, 44 on its two legs.
  • the rail 16 can thus form a correspondingly stable upper and / or lower end of the structure 1, the inwardly directed webs 43, 44 engaging in the grooves 14 and / or 15 on the components 10.
