Definitions

  • the invention relates to a mandrel and a sleeve for receiving and transmitting transverse forces to connect structural and civil engineering components such as roof panels, floor panels, ceilings, walls, supports, retaining walls or parts thereof with each other or with other components, for which the sleeve in one of the components to be connected, the mandrel is to be inserted and fastened in the other such that the mandrel and / or the sleeve protrudes from the component in question and the mandrel penetrates the sleeve, the mandrel and / or the sleeve having a bearing body for transmission the transverse forces against the component are provided.
  • the application primarily concerns components made of concrete, but is not excluded for other components.
  • the bearing body abruptly merges into a plate-shaped structure of a much larger diameter at the component edge; it is intended to hold the concrete together at the edge of the component around the exit point and prevent it from crumbling due to the overload there, but actually only moves it inwards by the plate thickness and prevents the crumbled concrete from falling out, i.e. the defect becomes visible.
  • the mandrel and sleeve serve to fix components in their plane, for which they must be able to absorb considerable forces in the transverse direction, while on the other hand the mandrel in the sleeve must be free to move longitudinally and remain so that the components are under the influence can expand and contract at different temperatures. Therefore, the mandrel and the sleeve must be corrosion-resistant and have to last for the long service life required by buildings, which is why they mostly consist of stainless steel, a precious material with high strength.
  • the surrounding concrete does not have nearly the same specific load-bearing capacity, which is why it has previously been forced to insert a disproportionate number of mandrels and sleeves in order to keep the concrete load in the boundary layer around the mandrels and sleeves within permissible limits. At the same time, however, this means inadequate use and waste of the precious, increasingly rare material from which the mandrels and sleeves are made, and waste of working time.
  • the invention has for its object to provide a remedy; their features emerge in detail from the first claim.
  • the bearing body distributes the force that occurs over a larger area in the concrete, so that its specific load becomes smaller, without the need to select a larger diameter for the mandrel and the sleeve itself, while the bearing body is not made of the same need to exist costly material; it is concreted in and thus protected against corrosion, and there is no requirement for permanent lubricity as for the mandrel and sleeve in the bearing body.
  • This makes it possible to achieve optimal material utilization for the concrete and for the mandrel and sleeve at the same time, i.e. Save material and labor costs.
  • the bearing body is only moderately stressed on the inside relative to the mandrel or the sleeve, namely far less than it would be in its place to reach concrete.
  • the load does not distribute itself approximately evenly over the recessed part of the mandrel and sleeve, but largely over a relatively short section near the outer end of the recessed part, with a steep tip directly at the edge of the relevant one Component. It is this steep peak that primarily stresses the concrete and has previously forced it to be dimensioned with very poor material utilization.
  • the bearing body according to the invention which under these circumstances only needs to cover a relatively short section from the outer end of the recessed part, not only reduces the specific stress where the greatest part of the stress occurs, but also builds up that steep stress peak from.
  • the bearing body has a certain elasticity according to the invention; minimal elastic changes in shape in the bearing body are sufficient so that the load is largely evened over its length both with respect to the mandrel or the sleeve and on the concrete side.
  • Plastics have this elasticity without further ado, and the elasticity of the bearing body made of a metallic material can be increased by suitable shaping.
  • the equalization of the load in particular the reduction of that steep load peak, not only relieves the concrete and the mandrel or the sleeve, but this also benefits the bearing body itself, so that none of the strength properties of the material to be used for it is particularly good high demands have to be made and some plastics meet this requirement.
  • the invention also includes the possibility of providing the bearing body only on the mandrel or only on the sleeve. This is considered when the two components in question consist of substances with very different strength properties; the bearing body will then be arranged in the component with a lower specific load capacity of its material.
  • the bearing body can be designed in different ways; it can have a cylindrical or cubic lateral surface or the shape of ribs or a body with ribs, which can be designed to be particularly elastic, and surround the part of the mandrel or the sleeve covered by it all around or partially.
  • the bearing body has a truncated cone-shaped or truncated pyramid-shaped surface, surrounds the portion of the mandrel or sleeve covered by it all or part and the larger diameter at the outer end of the inlet Has part of the mandrel or the sleeve.
  • the steep load peak mentioned is certainly greatly reduced by the bearing body, but even with good elasticity of the bearing body, one still has to reckon with the fact that the load there is 20 to 25% greater if the diameter of the bearing body is moderate and constant over time is.
  • the conical or truncated pyramid-shaped design has the advantage that the specific load is constant over the length of the bearing body thanks to the larger surface at the location of the greatest load and there increased elasticity. It is remarkable and an advantage of the invention that the equalization of the specific load occurs not only on the outside with respect to the concrete, but at least approximately also on the inside between the bearing body and the mandrel or the sleeve, thanks to the role of the bearing body as an elastic intermediate member in the case of conical or truncated pyramid-shaped formation of increasing flexibility towards the outside.
  • the clamping point of the mandrel or the sleeve which is concentrated on the component edge without a bearing body, is distributed over a longer section by the bearing body, and is used even more gently in the form of a truncated cone or pyramid.
  • a conical or truncated pyramid in the case of different load capacities of the components on the one hand in the material of lower load capacity, and on the other hand a cylindrical or cubic bearing body.
  • a bearing body which has the shape of ribs or a body with ribs can also be designed in such a way that it has a larger surface at one, outer end than at the other.
  • the synthetic resin can include is an epoxy resin, e.g. Bisphenol-A-epichlorohydrin with a tertiary amine as hardener, which requires higher temperatures for hardening, but their use is also recommended for shortening the hardening time in epoxy resins which are able to harden at room temperature.
  • Quartz sand is usually used as a filler, and in the case of particularly high strength requirements, acicular aluminum oxide can also be used.
  • suitable thermoplastics that meet high demands on mechanical properties and aging resistance, but unfortunately they are still relatively expensive.
  • the plastic bearing body can be mounted in any way, e.g. be glued on, the mandrel and the sleeve can also be encapsulated with it.
  • the bearing body can also consist of a metallic material and can then be welded, soldered, riveted, screwed or glued on; there are no concerns regarding the strength of the connection even in the latter case, and With this type of fastening, a high heating of the mandrel and sleeve material and thus the risk of a deterioration of its structure are avoided and an afterglow correcting this is saved.
  • the optimal length of the bearing body cannot simply be specified in relation to the mandrel diameter, because the diameter, the shape and the material properties of the bearing body also play a role here; with usual mandrel diameters, an optimal length of 7 to 10 cm results, which is not critical for the rest.
  • a fastening plate can be attached to the outer end of the part to be let in, which is also called “nail plate” in the construction field.
  • nail plate in the construction field.
  • the formwork of the first component is produced, the sleeves are nailed with their fastening plates from the inside against the formwork at the intended locations, the reinforcement is inserted if necessary and then the concrete mortar is removed and the formwork is removed after it has set. Then you insert the associated mandrels into the concreted-in sleeves, create joint insulation and formwork for the second component, if necessary bring in the reinforcement and then the concrete mortar and remove the formwork after it has set. If a further component to be connected with mandrels and sleeves is connected to the second component, the sleeves provided are attached to the adjacent formwork side of the second component as described above, and the installation process continues accordingly.
  • the rule can be given here that the concrete layer thickness around the mandrel or sleeve should be at least four times as large as the mandrel diameter. If this value has to be fallen short of, it is advisable to install a support reinforcement to distribute the concrete stress over a larger section.
  • the outer opening of the sleeve or the fastening plate has a cover which can be easily removed after installation, e.g. a glued-on film, and when the sleeve bore is closed at the other end.
  • the mandrel and the bore of the sleeve usually have a circular cross section, but this can also be selected differently, e.g. square, rectangular, polygonal or oval;
  • the outer shape of the sleeve is irrelevant in this connection, and the rest will depend on what rod and tube material is available.
  • the mandrel can also be designed as a tubular hollow body. With the same outside diameter, the permissible shear and bending stress is then smaller, but the maximum stress occurring at the clamping point is also smaller thanks to the effect of the bearing body. You can even make a tubular mandrel relatively thin-walled if you want to save material in view of moderate stress; on the other hand, it is often possible to accept a somewhat larger diameter under high loads. Compared to solid material of the same cross-section, a tube has the advantage of a greater section modulus and a smaller surface pressure in the surrounding body, and the latter also has an influence on the shear strength, even if this mainly depends on the cross-section.
  • Shearing is initiated by exceeding the permissible surface pressure (specific load) and consequently plastic deformation on the surface of the object as soon as the yield point is exceeded there; so it happens that a tube has a greater shear strength than a solid rod of the same cross-section and material.
  • Figures 1 to 4 and 7 to 10 have in common that a component edge K is indicated; this clarifies how far the object shown is to be let into the component. 1 and 2, a sleeve 11 with a bearing body 12 and a mounting plate 13 and a mandrel 14 with a bearing body 15 fitting into the sleeve 11 can be seen high loads or in components made of not very strong material and particularly suitable an epoxy resin with quartz sand filling, with which the parts therein are cast, and which can then also take over the mounting of the mounting plate 13, which would otherwise be connected to the sleeve 11 in a known manner.
  • FIG. 1 For better illustration, the subject of FIG. 1 is shown in perspective in FIG. 5, that of FIG. 2 in FIG. 6; 5, four holes can be seen in the mounting plate 13, through which the mounting plate is nailed when it is installed in the casing of the component.
  • 3 and 4 show a second embodiment with a sleeve 21 with a bearing body 22 and a mounting plate 23 and a mandrel 24 fitting into the sleeve with a bearing body 25.
  • the only remarkable difference compared to FIGS. 1 and 2 is that the bearing body 22 and 25 are cylindrical on the outside in this case. 3 and 4 would not look different if the cross section of the bearing bodies 22 and 25 were limited on the outside square or rectangular, and this would also represent an expedient embodiment of the subject matter of the invention.
  • FIG. 7 and 8 show a third embodiment with a sleeve 31 with a bearing body 32 and a fastening plate 33 and a mandrel 34 fitting into the sleeve 31 with a bearing body 35.
  • the bearing bodies 32 and 35 have the shape of plastic or metal a body with ribs, which becomes clear from Fig. 12, which represents the subject of Fig. 8 in perspective.
  • Finned tubes are commercially available; from this, for example, the bearing bodies 32 and 35 can be produced by simple parting and then e.g. stick on.
  • FIGS. 1 to 4 A comparison between FIGS. 1 to 4 suggests that the body can also be designed with ribs in such a way that it itself has a larger diameter at the outer end and / or further unload its ribs there, in order to thereby even out the load and a to achieve higher resilience.
  • Relatively thin ribs increase the overall elasticity of the body with ribs, which is easy to use, especially when made of metal; in this case he can e.g. be a cast or injection molded part.
  • FIG. 9 and 10 show in section a fourth embodiment with a sleeve 41 with a bearing body 42 and a mandrel 44 fitting into the sleeve 41 with a bearing body 45 which carries a fastening plate 43.
  • the bearing bodies 42 and 45 are hollow bodies in this case, which is clearly shown in the sectional view; 11 also illustrates the object of FIG. 10 in a perspective representation.
  • the bearing body 45 which is advantageous because it only attached at one end to the mandrel 44, the rest is self-supporting. This is not the case with the bearing body 42, which is why, for the sake of simplicity, it can also be designed with a diameter that remains constant over its length, as shown there and if the load there permits.
  • the bearing bodies 42 and 45 are preferably made of metal, together with the fastening plate 43, depending on the respective suitability, in one piece or composed of several parts and e.g. glued on.
  • the mandrel or the sleeve can be allowed to protrude from the respective component edge K, it is obvious that the mandrel and the sleeve can also be protruded.
  • the annular gap around the mandrel 44 does not need to be as deep and the bearing body 45 only has to be cantilevered for a less long part; Furthermore, this relocates the center of gravity of the transverse forces occurring between the mandrel and the sleeve precisely to the joint between the two components in question, so that the transverse forces act on the mandrel and sleeve with the same lever arm. Details of such an embodiment are evident from the figures shown.
