Definitions

  • the invention relates to an anchor that can be subjected to tensile stress for connecting two separate components.
  • the most common application example is the connection of balconies to a house, but the invention also makes it possible to build other attachments such as stairwells or lift shafts separately and to connect them to the associated structure.
  • the balcony floor has been designed as an extension or protrusion of the relevant ceiling separating the floors, so that it protrudes outside and drains considerable amounts of heat from the house in winter.
  • Part of living is that the walls and ceilings bordering a living space have the same temperature as the air in the living space.
  • efforts have recently been made to arrange balconies one above the other as a separate, albeit immediately adjoining extension outside of the heated and possibly heat-insulated construction volume to the outside.
  • Such an extension must be anchored to the house in a suitable manner, and without bridging a space that is to be provided between them and that should be filled with thermal insulation if possible. If the extension is completely self-supporting, it does not require any special anchoring to the house parallel to the house wall [apart from cases where it takes on tower-like dimensions ;; however, if it consists of balcony ceilings, which are only supported on the outside of the foundation, they must be provided with a shear-bearing connection with the house, for which only shear-transmitting anchors are known. The situation is different with the anchoring perpendicular to the wall of the house: this is necessary in any case and it must be able to absorb and transmit tensile forces.
  • Part of the invention consists in the knowledge that previous tie rods, such as those used for double-shell walls [double walls], are unsuitable for the present purpose owing to their rigidity in the direction of pull, which is not a matter of connecting two shells of the same wall in the same Building, but about the connection of two components, which in this sense represent mutually independent buildings. Buildings "work”, i.a. due to different thermal expansions, due to the influences and properties of each one; In earthquake areas there is also the fact that rigidly connected structures or components have little chance of survival. In the case of a house with continuous heat insulation on the outside and an attachment that is always exposed to the outside temperature, e.g. with balconies, there are particularly large differences in temperatures and thermal expansion in winter.
  • a dimension that can be used in practice is, for example, that an anchor may be loaded with a tensile force of 500 kg, and that its tension member migrates by approx. 3 to 5 mm in order to then stop at this or a slightly larger value a stop limiting the emigration distance to reach.
  • the elastic connection between the tension member and the sleeve is given a moderate pretension, so that the former does not begin to migrate out of the sleeve even with the smallest tensile forces.
  • This also applies to a second sleeve at the other end of the pulling element, if one is provided and the anchoring of the pulling element therein should also be resilient; the second sleeve doubled the entire emigration route then approximately, so that their arrangement in the uppermost floors of an extension can be expedient and there is no need to provide a correspondingly differently dimensioned sleeve at one end of the pulling element.
  • the installation of the new anchor takes place in principle as follows: In the component to be executed first - usually this is the house - the sleeves of the new anchor are inserted in the required number in the required places, then the associated tension members are inserted into the sleeves and anchored in it the second sleeves are also pushed on and anchored at their free end], so that the traction elements protrude according to their length, the thermal insulation and the plaster are applied to the component if necessary, and finally the other component, e.g. a balcony extension, executed; the traction elements protruding into the volume of the balcony ceilings are embedded and firmly clamped during setting and hardening thanks to the shrinkage of the mortar.
  • the other component e.g. a balcony extension
  • a preferred embodiment of the sleeve essentially consists of a housing in which there is a device for elastically resilient anchoring of the pulling element, a nail plate and a shaft connecting the housing and the nail plate and / or a foot at the rear [inner] end of the housing, so that the sleeve is inserted deep enough in its component.
  • the foot also makes it possible to move the housing to the edge of the component and combine it there with the nail plate.
  • a second sleeve is provided in the other component, it can be designed in essentially the same way or can be provided with a tubular shaft without a nail plate, which extends from its housing at least to the edge of the component into which it is to be inserted.
  • the housing there can be a base which is displaceable in the longitudinal axis direction for anchoring the tension member, further after the open end of the sleeve a pressure-absorbing component and finally a ge-attached in the housing or by this itself formed abutment for the elastically absorbing component.
  • the tension member has an external thread at its end to be anchored in the sleeve and the base has a nut with the corresponding internal thread, then the tension member can be anchored in the sleeve by screwing in m 3 n.
  • the end of the pulling element can be T-shaped and can be inserted through a corresponding, elongated recess in the base.
  • This can be a disc spring column, a compression spring or an element made of natural rubber, a synthetic elastomer or some other elastic material provided with a bore for the passage of the tension member.
  • the tension element can, if necessary, be corrugated on the outside and / or bent or bent at the end, spread or provided with a laterally projecting end piece. It is simple and advantageous to provide a tension rod as the tension member, the cross section of which is dimensioned with regard to the tension force to be transmitted, i.e. the cross section need not be larger. If this is 500 kg according to the example mentioned, round material of 10 mm diameter, made of stainless steel, is sufficient for the tension rod, as is customary for support and tension anchors for known reasons. This relatively thin tension rod is correspondingly flexible in the transverse direction, which is quite desirable given its use; It is not his job to absorb lateral forces.
  • the new anchor can transmit much greater shear forces in addition to the tensile force than without the bush and the tension rod is relieved of shear forces.
  • the new anchor is a combined traction and shear anchor, which, for example, can not only pull a balcony against the house, but can also support it on the house side.
  • the bushing is partially inserted into the sleeve and is guided there with at least one play, at least in one direction, the direction of the transverse force; at the other end, the bushing with the tension rod inserted into it must be inserted in the other component.
  • the tension rod and the bushing are taken up by one and the same part, a mandrel, which serves as a pulling element and whose cross section is dimensioned such that in addition to the tensile force, it is also able to absorb a shear force of the size of the values customary or desirable for shear force mandrels. It therefore turns out, as a solid rod of circular cross section, to be considerably thicker than the previously described tension rod, which is flexible in the transverse direction and is unable to absorb any significant transverse forces.
  • a hollow profile is also possible for the mandrel, it saves material in a known manner.
  • the transverse force it is also expedient for the mandrel if the sleeve in the part receiving it is dimensioned on the inside in such a way that it is guided in it with little play in at least one direction.
  • the section modulus of the mandrel or the previously described bushing must be used; A further material saving is accordingly achieved if the bush or the mandrel has a greater section modulus in the transverse force direction than in the direction perpendicular thereto.
  • a flattened profile, a double-T profile or the like also comes with the mandrel. in Be traditional, especially if you provide him with a different anchoring in the sleeve than by screwing it in.
  • the anchor parts [sleeve and sleeve or mandrel] or at least one of them outside Provides the area of the part to be let into the respective component, subsequently at its outer end and at least over part of its length, with a reinforcement which has a larger surface area than the section of the sleeve or the bushing or the mandrel covered by the reinforcement. If the housing described above is arranged adjoining the component edge in the case of the sleeve, it already represents a reinforcement in this sense.
  • the reinforcement first of all increases the area transmitting the transverse force to the component at its edge, where the load is greatest, thereby reducing the maximum specific load occurring at this point.
  • the reinforcement is designed or consists of a material such that it is elastically more flexible than the sleeve or the bushing or the mandrel and as the material of the component surrounding it.
  • Such an elastically flexible reinforcement can be made from a suitably designed body consist of a metallic material, for example from a hollow body with enough nacngiebigen wall surfaces, or by projecting ribs or the like on it. are provided; but it can also consist of a suitable plastic, such as a two-component casting resin, with which the anchor part in question is cast, and to which a filler can be added; this has an influence on the strength as well as on the elasticity.
  • Another purpose is when the tension rod is covered over a part of its length, at least adjoining, or additionally enclosing, the portion bridging the gap between the components, by a padding made of foam or another soft elastic material. This is not about the transmission of forces and specific loads, the tension rod does not transmit any force in the transverse direction, rather the deflection of the tension rod in the event of dislocations between the components is distributed over a larger part of its length, i.e. the bending stress is reduced or reduced to a minimum.
  • the foam does not transmit any forces; where it surrounds the tension rod, it only keeps away from the tension rod what would otherwise relentlessly surround it, be it part of the sleeve or directly the component itself. If the foam covering also extends into or over the space between the components, it fulfills another purpose there, in that it offers the advantage that a different tension rod with a differently arranged covering is not required for each space width.
  • the tension member be it a tension rod or a mandrel
  • the tension member can have a collar where it enters the sleeve and exits from it, which is arranged in such a way that it is anchored when the tension member is anchored in the sleeve, for example when screwing it in the Ge réelle is tightened and thereby causes a preload of the elastic component in the sleeve and a seal of the sleeve opening.
  • a seal can also be inserted for the latter purpose.
  • the federal government stops the train organ even if it is not guided in the sleeve over a longer section, without special stress in its rest position in the direction of the sleeve axis, which is important for subsequent concreting of the tension member in the other component.
  • the pretension can also be achieved without the collar by providing a stop for the tension member in the housing behind the nut - this can also be the housing wall at the rear end of the housing -; If the pulling element is screwed in as far as this stop and then tightened a little further, the nut moves a little forward with the base and presses the elastic component, e.g. the disc spring column, something together.
  • the elastic component e.g. the disc spring column
  • a bearing-like approach can be attached to the sleeve or sleeves where the tension member exits therefrom, which can also be used to insert a seal between it and the tension member.
  • the inventor was not satisfied with this opinion and finally found a solution to this particular problem.
  • the starting point was the following consideration: As already indicated here, offers the new anchor with a soft elastic covering of the tension rod over a part of its length to be let in with regard to dislocations between the components the advantage that it then distributes its forced bending over a larger portion of its length; however, these are the minimal offsets and bends that can occur in buildings of normal height.
  • connection between the sleeve to be inserted in one component or between at least one of the sleeves to be inserted in both components and the tension member anchored therein can be pivoted in at least one direction; at least to such an extent that the new anchor can even follow the considerable mutual changes in position in this case between the two components, without corresponding changes in shape and bending stress occurring in the tension member. It remains essentially free of this.
  • the design of the new anchor for this special purpose depends in particular on whether the separate, but immediately subsequent annex is supported either on its own or only on the outside on its foundation, but on the house side, but bearing on the house, floor by floor.
  • the latter is particularly suitable for balconies, which then only sink outside in cold weather, i.e. tilt slightly downwards, so that the tie rod connection between the house and the balcony must be able to follow the hinge-like, at least to the extent necessary for this.
  • the otherwise minimal transverse play of the tension member in the laterally adjacent sleeve parts need only be so large that the tension member therein in the required Extent is pivotable.
  • the pulling element cannot be pivoted in the sleeve in which it is resiliently anchored in the pulling direction, it can for this purpose be pivotably fastened in the other component in a further sleeve to be inserted there, e.g.
  • Another way of designing the new anchor so that it can follow the hinge-like movement between the components without a corresponding change in shape and bending stress of its tension member is that it is in the sleeve to be inserted in one component or in one of the two components sleeves to be let is stored in an elastic lining located therein, which is dimensioned so that it holds the tension member during installation in its starting position, and that it can be pivoted therein to the required extent without considerable force.
  • the new anchor is also able to follow the dislocations in height without bending stress of its tension member, as can occur between very high components in their upper parts if the cultivation as a whole is also supported on the foundation.
  • the sleeves embedded in the two components always keep their axis direction, but they are displaced against each other in the vertical direction, especially when the outside temperature changes. An additional displacement in the horizontal direction is noticeably only possible in the practically scarcely occurring case where the cultivation is very wide, i.e. has very large dimensions parallel to the house wall in the horizontal direction.
  • Another embodiment of the new anchor serves the same application, which will now be described in conclusion.
  • he has one sleeve and one sleeve in the other, essentially the same design, each with a housing directly on the respective component edge, in which the pulling element is elastically flexible in the pulling direction and has transverse play in the adjacent sleeve parts - the elastic resilient fastening on both sides thus doubles the travel in the direction of pull, which is particularly advantageous in the upper area of very tall buildings -;
  • the only difference between the two housings is that one ends in a tubular extension, the length of which is dimensioned such that the traction element represents it can be inserted more or less deeply when screwing in, so that it does not have to have a different length for each distance between the components.
  • the diameter of the extension as well as the previously mentioned transverse play are dimensioned such that the tension member can be pivoted in both sleeves at least to the extent required for this application.
  • inventive merit lies above all in the technically and economically fully satisfactory solution to a technical problem that has been around for years.
  • the sleeve 1 has a nail plate 16 at the edge of the component A, a housing 11 at the other end and a tubular shaft 17a between them.
  • a base 12 can be seen, connected to a nut 13 for screwing in a tension rod 21 as a tension member, which is let into the component B at its other end and is bent there for better anchoring.
  • a disc spring column 14 is located between the base 12 and an abutment 15, which in this case is also one of the housing walls. If you screw the tension rod 21 up to its stop on the opposite housing wall and then tighten it a little, the plate spring column 14 receives a prestress.
  • the tension rod 21 migrates out of the sleeve 1 until, with increasing tensile force, the fully compressed disc spring column 14 offers a stop and thus limits the migration path.
  • the base 12 must be prevented from rotating when the tie rod 21 is screwed into the nut 13; this can be ensured in various known or obvious ways, for example by giving the housing 11 a square cross section, as in the examples shown, and making the base 12 square, as it fits, on the outside.
  • the plate spring column 14 is guided outside through the housing 11, which in Fig.l as well is cut in a diagonal plane in the following figures, so that a distance between the plate spring column 14 and the housing 11 is visible in the sectional plane running through two opposite housing edges.
  • the embodiment according to FIG. 2 differs from this mainly by a different arrangement of the same housing 11 of the sleeve 1, namely directly at the edge of the component A and combined there with the nail plate 16.
  • the parts in the housing 11 are also the same previously in FIG . So that the sleeve 1 is anchored deep enough in the component A, it then has a foot 18 a on the housing 11, which essentially resembles the end of a tension rod 22 to be inserted in component B, which here is correspondingly shorter than the tension rod 21 of FIG. l is because it does not extend so far into the sleeve 1. Compared to Fig.l, the shaft 17a there is saved.
  • part of the tension rod 22 is encased with a foam padding 55, so that the tension rod 22 bends due to a small displacement between components A and B, or because component B, as a balcony floor, assumes a slight inclination affects a larger part of the tension rod length, ie the bending stress is reduced, compared to "hard" insertion of the tension rod 22 from the component edge B. If, as shown, the padding 55 protrudes a bit into the space between the components A and B, it is not necessary to provide a different tension rod with a differently arranged padding 55 for each space width, but this should in any case extend to the component edge B.
  • the sleeve 1 does not exert any bending stress on the tension rod 22 in the event of displacements or inclinations between the components A and B, because it can be pivoted sufficiently in the housing 11 in FIG. So that it still maintains its position in the direction of the sleeve longitudinal axis when it is let into component B, it can be screwed in with some pretension; This is achieved even better if it is provided with a collar 6 where it emerges from the sleeve, which is in the Screwing the tension rod 22 with prestress firmly against the sleeve opening and sealing it on top of that during the subsequent installation work.
  • the collar 5 does not hinder the pivoting of the tension rod 22 in the housing 11 if this is forced by a displacement or inclination between the components A and B, especially since a tension force that always raises the collar 6 from the housing 11 or from the nail plate 16 occurs.
  • FIG. 3 the same housing 11 as in FIG. 1 with the same parts 12 to 14 is arranged in it at the same location on the sleeve 1 as there, as is the nail plate 16; a differently shaped shaft 17b extends between them.
  • a pull rod 23 is anchored in the housing 11 as in Fig.l, but here it is surrounded by a bush 31, which is closed at the end in component B by a washer 71. After screwing the tension rod 23 into the nut 13, sliding the bush 31 and tightening a nut 73 provided in front of the washer 71, the tension rod 23 tightens the bush 31 and receives the anchoring of the tension rod 23 in the sleeve 1 a pretension.
  • Be this embodiment of the new armature tensile forces between the components A and B are absorbed only by the tension rod 23, lateral forces only by the sleeve 31 designed for this.
  • the bush 31 can be given a greater section modulus in the direction in which the transverse force acts than in the direction perpendicular thereto, in the example shown in the form of a tube of rectangular cross section. Then it makes sense to do this also with the shaft 17b and to choose a square tube with a rectangular cross-section in which the bushing 31 is guided with at least a slight play in the transverse force direction.
  • a reinforcement 51 is applied to the shaft 17 b
  • a reinforcement 52 is applied to the bush 31, preferably consisting of a material which is elastically more flexible than the anchor parts enveloped by it and the surrounding material of the construction parts, whereby the surface pressure occurring in this due to the shear force is evened out to a decisive extent, in particular the otherwise occurring peak load on the component edge is reduced.
  • the reinforcement 52 similar to the padding 55 in FIG. 2, can also be extended beyond the component edge B, for example at least where far that its end is at a distance equal to the smallest occurring gap width between the components A and B from the component edge A. ; then it is not necessary to have different bushings 31 with differently arranged reinforcement 52 available for different such gap widths.
  • FIG. 4 shows a modification of the object from FIG. 3, in which the same sleeve 1 as in FIG. 2 is used, which here only has a tubular, in the space between the components A and B at most as far as the smallest occurring Gap width is 19, extending approach 19a, the task of which is to transmit the transverse force absorbed by a sleeve 32 to the sleeve 1.
  • the sleeve 32 is correspondingly shorter, as is a tension rod 24 which is guided through the sleeve 32 and is also clamped with this relative to the sleeve 1 as in Figure 3; the reinforcement 52 is also the same as there, and there was no need for reinforcement on the sleeve 1 because there is the housing 11 at the relevant point, which already has a larger cross section than the rest of the sleeve 1. If the material of the component A had a low compressive strength, the sleeve 1 of FIG. 4 would advantageously also be surrounded by a well elastic reinforcement, which in particular would also have to make the cross-sectional transition from the housing 11 to the foot 18a less erratic. Even in the case of the object of FIG. 4, the bush 32 could receive a greater section modulus in the transverse force direction than in the direction perpendicular to this.
  • the sleeve 1 is essentially the same as in Fig.l, apart from a larger clear width in the shaft 17c, because instead of the tension rod here it now has to receive a mandrel 41 which, in addition to the tensile force between components A and B, also absorbs the transverse force, so that the new anchor can also serve as a support anchor.
  • a pin 72 guided through at the other end serves to screw in the mandrel 41 and to anchor it more firmly in the component B into which it is to be inserted.
  • This also serves the truncated cone shape of reinforcements 53, 54, about which the same should be said as before about reinforcements 51, 52.
  • the housing 11 is arranged on the component edge A, so that a mandrel made of solid material which is introduced there and projects into a tubular foot 18b for the purpose of transmitting the transverse force and guidance is deposited from the thread to at most a core diameter of the thread, e.g. would have to be turned, which would be very expensive, also in terms of material consumption.
  • This can be avoided by assembling the mandrel from two parts, namely from a foot part 42 of smaller diameter and from a pushed-on pipe part 43 of larger diameter, so that one can cut the thread on the pushed-on end of the latter to screw it into the nut 13 .
  • a variant not shown to the subject of 6 is that the sleeve from FIG. 4 is used and the foot part 42 is either omitted from the mandrel or, to keep it correspondingly shorter, is only pushed in completely for reinforcement as shown in FIG.
  • FIG. 7 shows a tension rod 25 which is inserted and anchored at both ends in a sleeve 1 and 1 ', one of which is to be let in component A, the other in component B.
  • the sleeve 1 is similar to that of FIG. 1, and the sleeve 1 'differs from this in that the nail plate 16 is omitted and by a longer tubular shaft 19b which is so long that it extends at least to the edge of the component B, but also can reach into the space between components A and B, so that it is not necessary to provide a different tube shank length for each other space width.
  • the component edge there can vary between B and B ', with component edge A not thought to be crazy.
  • a variant, not shown, of the above object uses the one shown in FIG. 2 instead of the sleeve 1 shown in FIG. 7; the tension rod 25 is then only correspondingly shorter.
  • FIG. 8a and 8b illustrate the new anchor according to Fig.l and Fig.5 in a perspective view.
  • the cube shape of the housing 11 and its position can be seen in particular.
  • FIGS. 9 and 10 two structurally fundamentally different arrangements of an extension B to a house A are shown in the floor plan, which also have different requirements with regard to anchoring.
  • 93 can be a balcony or one of more or less numerous balconies arranged one above the other, which is only on the outside supported on the foundation by means of support 98, for example made of steel, and is connected on the inside via known support anchors 82 to a ceiling 91 in the house, which merely transmit transverse forces, that is to say carry the balcony ceiling on the house side and secure the balcony parallel to the house wall;
  • Such anchors usually consist of a sleeve in one and a mandrel in the other component, from which it protrudes and protrudes into the sleeve, movable longitudinally in the latter.
  • the support anchors 82 are drawn in FIG. 9 with the reinforcements proposed here and drawn in FIGS. 3 to 6, because the reinforcements are also advantageous for this. So that the balcony extension cannot tip away from the house, additional tie rods 81 in the form of the new anchor, for example according to Fig.l, are inserted. Instead of the support anchors / and the new tie rods 81, one of those embodiments of the new anchor which could also transmit a transverse force in addition to the tensile force and which are shown in FIGS. 3 to 6 could also be used.

Even if the distances between the two components were to be significantly larger in the future, their connection with the new anchor would not pose any new problems.

  • the installation is as follows: after the sleeve 1 has been concreted in, the tension rod 26 is screwed into it until a prestress of the spring 14 is achieved by abutment of the bush 44 on a shaft 17 d, and then the sleeve 1 'with its nut 63 located therein is screwed on the pull rod 28 up to the stop of the flange 16 'belonging to the sleeve 1' on the formwork or other limitation on the already-constructed saddle part A made for component B.
  • FIG. 15 The following exemplary embodiment, shown in FIG. 15, is also suitable for the application according to FIG. 10, but here, in the case of very high components and therefore considerable height differences in their upper region at extreme temperatures, the sleeves 1, 1 'while maintaining them Axis direction can be moved against each other again and again.
  • a tension rod 27 is now provided which, thanks to play in both sleeves 1, 1 ', can be pivoted to the required extent in the transverse direction and is therefore not subjected to any bending when the sleeves are moved in this way.
  • a tubular extension 11 e on the housing 11 of the sleeve 1 ' is dimensioned so that the tie rod 27 can be screwed in more or less deeply to adapt to different distances between the components A and B, and that it does not hinder the pivoting movement of the tie rod end is.
  • Collars 62 are designed to be able to be preloaded on the springs 14 and for sealing on the tension rod 27; you can e.g. secure with a lock nut or with adhesive applied to the thread.
  • Such a tie rod cannot transmit a shear force in any direction, so it needs to be supplemented with a tie rod.
  • a suitable one for applications with swiveling or displacing the components is shown in FIG. 16, where a mandrel 91 with a reinforcement 58 in component B, a sleeve 92 provided with a soft-elastic lining 82 and a reinforcement 59 and a nail plate 16 a in component A is to be let in.
  • the section TT is shown in Fig.16a; the longer side of the sleeve cross-section and thus the direction of movement of the mandrel in the sleeve must of course be installed vertically, while its horizontal position in the drawing [Fig.16a] is only due to the arrangement of the cuts. Transversely to this this anchor has no significant freedom of movement, so that it defines the attachment to wind forces, which, by the way, only the embodiment of the new anchor shown in Fig. 15 does not by itself.
  • the liner 82 holds the mandrel 91 in its initial position during installation, but yields slightly when loaded to a minimal residual volume, for example if it consists of foam.
