Definitions

  • the invention relates to a cantilever slab and / or joint element for reinforced building constructions, with a one-part or multi-part structure designed to accommodate tensile and / or pressure reinforcement elements and, optionally, transverse force bars, whereby to accommodate the tension and / or pressure reinforcement elements through openings extending in the structure approximately transversely to a vertical longitudinal center plane thereof and formed by tubular bodies inserted or usable in the structure are provided.
  • 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.
  • a component which can be used as a joint and / or dilatation and / or cantilever element has also already become known (EP-B-0 442 130), in which openings are provided for receiving pieces of pipe.
  • the reinforcement elements can pass through these pipe sections the concrete structure are passed through, so that a continuous reinforcement is guaranteed.
  • a tube that is smooth on the outer surface is used, which can accordingly be easily inserted into a prepared through opening.
  • the present invention has for its object to provide a tubular body for cantilever and / or joint elements of the type mentioned, which is economical to manufacture and can be easily assembled.
  • this is achieved by means of a tubular body which can be inserted into a through opening prepared in the building structure and has a plurality of ribs on its outer surface which run at least approximately in the circumferential direction and via which the tubular body can be positively and / or positively supported on the inner wall of the through opening in the building body.
  • This measure according to the invention ensures a very economical production possibility for such tubular bodies, with the additional advantage that the assembly is very simple. Since the ribs running in the circumferential direction ensure that the outer surface of the tubular body and the inner wall of the through opening do not lie against one another over the full area, the tubular body can be pushed into the through opening relatively easily and without breaking off sections of the structural body. However, because the ribs running in the circumferential direction lie, so to speak, transversely to the direction of insertion, they provide an optimal inhibition against retraction. Therefore, it is only possible with special force to pull the tubular body out of the through opening after insertion.
  • tubular body in the structure is only necessary to the extent that securing against loss is to be ensured.
  • tubular body should of course be appropriately secured against displacement when the tensile or pressure reinforcement elements are inserted.
  • the outer dimensions of the ribs are slightly larger than the dimensions of the through openings in the structure, so that the tubular body can be inserted into a through opening in the manner of a snug fit.
  • Corresponding indentations should not be dug or the inner wall of the through opening should be scraped out, but sufficient and optimal fastening of the tubular body in the through opening in the building structure is created solely by a suitable fit. This is also supported by the material, because the sections of the passage opening remaining between the individual ribs can be relieved again after insertion of the tubular body and therefore cause a corresponding lock against pulling out for the ribs running in the circumferential direction on the tubular body.
  • a plurality of ribs running parallel and at a distance from one another are provided on the outer surface of the tubular body. Care is taken to ensure that there is a corresponding distance between the ribs so as not to prevent the possibility of a retraction lock.
  • the arrangement of a plurality of ribs running parallel to one another in any case enables the tubular body to be exactly centered in the through-opening, since, as viewed over the length of the tubular body, there is support on a large number of ribs.
  • the ribs run helically on the surface of the tubular body. Even if the possibility of a snug fit is taken into account, it is conceivable that the assembly can be carried out even more simply and effectively with a slight twisting operation. Nevertheless, there is an additional holding force if the tubular bodies want to be pulled out in the axial direction. The retention force is thus further increased by the helical ribs.
  • the length of the tubular body is greater than the thickness of the structural body, and if one or more rib (s) is or are provided on the outer surface of the ends of the tubular body projecting on both sides over the front sides of the structural body.
  • the area of the tubular body projecting above the structure is also optimally embedded in the concrete, the one or more ribs on these projecting areas additionally providing an optimal seal with respect to the inner area of the tubular body.
  • a rib with a larger diameter than the other ribs is provided at one end or at a distance from one end of the tubular body to form a stop flange.
  • the tubular body must then always be inserted from the same side into the through opening in the structure, but there is always a corresponding stop flange to determine the depth of penetration.
  • one or more bore (s) radially guided from the inside to the outside is or are provided in the tubular body. It is expedient if the bores open outwards between two ribs and preferably lead upwards in the vertical position in the installed position of the tubular body. This creates the possibility that the reinforcement passed through the tubular body is completely surrounded by the concrete or the concrete milk and thus no corrosion problems can result. Any air bubbles remaining in the tubular body can then escape through the radially outward bores into the cavities formed between the ribs.
  • 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 tubular bodies 3 inserted into through openings. Through the tubular body 3, the reinforcement elements passing through a ceiling slab and the adjoining cantilever slab area can be inserted in the tensile and pressure areas. This means there are no interruptions in the reinforcement.
  • transverse force rods 4 can be used in the cantilever plate element, which one have an oblique to the horizontal central portion 5 and each have a straight region 6, 7 on both sides of the structure 1. These areas 6, 7 can for example run axially parallel to the central axis 8, 9 of the corresponding tubular body 3.
  • the structure 1 consists of several components 10, these components being shown in FIGS. 3 and 4.
  • the transverse force rods 4 are inserted here with their obliquely running central section 5 into a groove 11 formed on a lateral edge boundary of a component 10, the open area of the groove 11 being closed accordingly by the approach of the next component 10.
  • a shear force rod inserted in this way is thereby held captive.
  • the mutual connection between the components 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 components 10 Area are elastic.
  • the springs 12 and grooves 13 or in addition to these, a correspondingly stable mounting and alignment of the components 10 can be ensured if they have grooves 14, 15 on both sides at their upper and / or lower edge region, in which case a corresponding U-shaped holding rail 16 is attached or pushed on.
  • the measures according to the invention can of course also be used in other constructions of cantilever plate and / or joint elements.
  • the cantilever plates and / or joint elements can thus also be designed as one-piece elements or else consist of upper and lower parts which are placed one on top of the other in the vertical direction.
  • the present invention is essentially about the special design of the tubular body 3, which serve to accommodate tension and / or compression reinforcement elements.
  • through openings 2 are provided in the structural body 1 or in the components forming such a drilling body 1, into which the tubular bodies 3 can be inserted.
  • the tubular body 3 has on its outer surface 45 a plurality of ribs 17, running at least approximately in the circumferential direction, by means of which the tubular body 3 can be positively and / or positively supported on the inner wall 46 of the through opening 2 in the structural body 1.
  • a suitable fit a corresponding friction of the tubular body used in the through opening 2 is achieved, so that a corresponding frictional connection is given.
  • the outer dimensions B of the ribs 17 are slightly larger than the dimensions C of the through openings 2.
  • the dimensional differences are chosen such that a correspondingly simple insertion of the tubular body into the through opening is possible without the risk a breakout of the structure 1, which generally consists of foam, would be given.
  • a plurality of ribs 17 running parallel to one another at a distance are expediently provided on the outer surface 45 of the tubular body 3. Multiple support on the inner wall 46 of the through opening 2 is thereby possible, so that there can never be a tilting movement of the tubular bodies 3 used, even if there were a one-sided load.
  • a further embodiment variant provides that the ribs 17 are not designed as elevations lying parallel to one another, but rather run helically on the surface 45 of the tubular body 3.
  • the tubular body 3 can be used in a kind of screw rotation, so that there is an additional retaining force if the tubular body 3 would only be loaded in the axial direction.
  • the length X of the tubular body 3 is greater than the thickness D of the structural body 1, so that the tubular body 3 with its two ends can protrude beyond the front side 40 of the structural body 1.
  • the tubular body protrudes only on one side, but for reasons of strength and the load options which are the same on both ends, it makes sense to allow the tubular body 3 to protrude with both ends.
  • One or more ribs 19 are also provided on the outer surface 45 of the projecting ends of the tubular body 3, the ribs 19 being enclosed by the filled-in concrete or the concrete milk and thus forming a seal practically similar to a labyrinth seal.
  • a special rib with a larger diameter E than the other ribs 17 is provided to form a stop flange 18.
  • a constant depth of penetration of the tubular body 3 into the through opening 2 is thus always possible.
  • the stop flange 18 therefore always abuts the front side 40 of the structure 1.
  • one or more bores 20 which are guided radially outward from the inside 48 can be provided, these bores 20 usefully opening out between two ribs 17 in each case and preferably in the installed position of the tubular body 3 in vertically upwards.
  • Such a solution is advantageous if there is to be a guarantee that the section of a tensile or compressive reinforcement lying in the tubular body 3 is completely enclosed with concrete or concrete milk. Air still in the tubular body 3 can then escape at the highest point through the bores 20, for which the circumferentially closed cavities remaining between the ribs 17 are outstandingly suitable.
  • the tubular body according to the invention is advantageously made of plastic, although other materials can also be used. It would also be conceivable to make such tubular bodies 3 of metal, e.g. Aluminum or stainless steel.
  • ribs 17 and 19 and a stop flange 18 were mentioned.
  • cross sections of these ribs to be used, with regard to the spacing of the ribs from one another and with regard to the formation of such ribs.
  • cross-section the ribs e.g. sawtooth-shaped to have little resistance when pushed in, but still achieve an optimal effect against pulling out.
  • ribs can be formed in the same way by a large number of successive grooves. Only the principle should always be realized that there are several, at least approximately in the circumferential direction, ribs on the outer surface of the tubular body, by means of which the tubular body can be positively and / or positively supported on the inner wall of the through opening. Only through these measures can an optimal and simple production, simple assembly and a secure hold of the tubular body be guaranteed.
