Definitions

  • the invention relates to a sleeve / mandrel connection for the transmission of Lateral forces between two neighboring components, in particular concrete components, the sleeve in one component, the mandrel partially in the other Component installed, in particular concreted, partially from this Component protrudes such that the mandrel with its protruding part under Crossing the joint between the components can be inserted into the sleeve, the sleeve and / or the mandrel for better embedding in the respective Have component pressure distribution elements, the above and below spaced from the sleeve or mandrel and are in the respective Insert the component.
  • Such a sleeve / mandrel connection is known from DE-A 197 39 446.
  • the sleeve and the mandrel each have one to be positioned on the joint Face plate on and the above and below the sleeve or mandrel arranged pressure distribution elements consist of U-shaped curved reinforcing bars that are laid flat and each welded at its apex to the upper or lower edge of the face plate are, whereas the free ends horizontally into the component extend into it.
  • the present invention has for its object the known Sleeve / mandrel connections with regard to their pressure distribution elements improve, so that on the one hand high forces with comparatively low Concrete stresses are transmitted, on the other hand an inexpensive Manufacturing is guaranteed. In addition, the laying of the on-site Connection reinforcement in no way through the pressure distribution elements become more difficult.
  • This special course of the pressure distribution elements initially offers the Advantage of a very effective anchoring through the horizontal connecting pieces, which run relatively far from the joint inside the component and thus the forces occurring at the joint far into the interior of the component bring in.
  • these have horizontal connectors but also the advantage that reinforcing bars of the connecting reinforcement, the should run approximately parallel to the joint, no longer, as is often the case at present Fall, in the longitudinal direction in the closed reinforcement bracket of the sleeve / mandrel connection need to be threaded, but across their Longitudinal extension in the space between the pressure distribution element and sleeve or mandrel can be inserted.
  • the vertical connectors of the pressure distribution elements are not an obstacle because they have been moved to the joint.
  • Another advantage of the invention is that the above vertical connectors for stiffening the faceplate or the sleeve or the mandrel can be used; thereby eliminated the triangular necessary in the prior art mentioned at the beginning Stiffening plates.
  • the pressure distribution elements not at the top and at the bottom, but only at the top or at the top To be provided on the underside.
  • the vertical connectors are then only still required, the approximately horizontal sections of the pressure distribution elements at their ends facing the joint with the sleeve or to connect the thorn - be it directly or indirectly. But it lies there also within the scope of the invention, towards the vertical connecting pieces waive and the desired connection via a joint plate, or in otherwise.
  • This alternative is characterized by particularly low material costs and thus also low manufacturing costs.
  • the Installation easier because the risk of collision with the customer Connection reinforcement reduced.
  • the power transmission is hardly reduced if the pressure distribution elements at the load-bearing Part, usually with the sleeve on the top, in the case of the load-giving Partly, usually arranged on the underside of the mandrel become.
  • top and bottom of the sleeve / mandrel connection arranged sections of the pressure distribution elements extend expediently offset upwards or downwards relative to the sleeve or mandrel, because this results in more favorable static conditions for power transmission surrender. But it is also within the scope of the invention to dispense with such a height offset and the sections mentioned only in the upper or lower area of the sleeve or mandrel.
  • the sleeve is preferably at its joint end with an end plate connected; then they can be bent approximately in the vertical direction Areas are welded extensively to the faceplate to close them stiffen and the transverse forces introduced into them optimally into the concrete transfer.
  • the pressure distribution element regardless of whether the Sleeve has an end plate or not, with its approximately vertical connectors be welded directly to the sleeve wall if this has a sufficiently thick wall.
  • a particularly expedient development of the invention consists in that at least one of the upper and / or lower sections of the pressure distribution element, preferably all upper and / or lower sections as they run from the joint into the component opposite are inclined towards the interior of the component, that is to say towards one another approach.
  • the inclination to the horizontal can be chosen so strongly that there is only a small distance remains relative to the sleeve or the mandrel. Appropriately this distance should be chosen so that it can still be inserted from the side of reinforcement bars running parallel to the joint permitted, although it is quite legitimate to briefly manually clear the gap to enlarge by elastic expansion so that the bars of the connecting reinforcement can happen.
  • the sleeve itself is hardly any worth mentioning Exposed to stress.
  • Your wall thickness can be reduced to less than 50%, usually even less than 30% of the end plate wall thickness can be reduced and plastic is sufficient.
  • the sleeve through a foamed plastic body for example to replace a styrofoam body that is only used as a displacement body acts and is removed after stripping. In this case, the So sleeve only exist through a hole in the concrete.
  • mandrel in particular an upright rectangular profile. It is expedient at his in leave the component directed end open, so that the mandrel when concreting fills with concrete and is reinforced accordingly. In the front area A closure of the mandrel is recommended so that the concrete does not pass through the thorn flows off.
  • the sleeve / mandrel connection described can be found in the known Materials, especially stainless steel. But it is also within the scope of the invention, for reasons of cost stainless steel only up to a distance of about 3 to 10 cm from the joint and the subsequent parts made of reinforcing steel or structural steel.
  • the stainless steel parts and the concrete or structural steel parts are welded together connected with each other.
  • Figures 1 and 2 can be seen in the left half of the picture, in the Component A, a mandrel 1 with a pressure distribution element 2 and in the right half of the picture, in component B, a matching sleeve 3 with a Pressure distribution element 4. Mandrel and sleeve are shown roughly as as they are stuck together in concrete.
  • To the sleeve 3 also has an end plate 5, which at the joint end the sleeve is arranged and in addition to its static function for attachment the sleeve on the formwork. It has multiple openings 5a, see Figure 3, provided.
  • the mandrel a rectangular cross section and is installed upright, whereas the Sleeve has an approximately square cross section.
  • Components A and B can be moved horizontally relative to each other in the direction of the joint, to compensate for different thermal expansions. Same thing also applies in the longitudinal direction of the mandrel and sleeve.
  • the rod sections 2a to f or 4a to f each by horizontal connecting pieces, namely the connecting pieces 2g, 2h and 4g, 4h connected to each other - Also preferably over arches with a radius of at least one Centimeters or at least twice the rod diameter.
  • the pressure distribution elements 2 and 4 expediently consist of one single continuous rod material, such that the joint on the mandrel or on the end plate, so that no additional welding work are necessary to connect the rod ends together. But it is also in the context of the invention, the pressure distribution elements on others Place to connect or put them together from several rod sections to weld, especially if the Joint stainless steel can be used in the more distant area of reinforcing steel should.
  • rod sections are not so harmonious let it go through as drawn, but through it by others To make bends wavy or stepped.
  • rod sections 2a to 2d or 4a to 4d not exactly perpendicular to the joint, but rather somewhat oblique leave, such as the view from above according to Figure 2 shows.
  • the rod sections run from their fastening slightly apart at the thorn; in the case of the sleeve is recommended the reverse course, because here the rod sections on the face plate already start relatively far apart.
  • the rod sections can also be opposite be inclined to the horizontal plane, as in a later embodiment is still received.
  • Figures 6 and 7 still show different sleeve shapes.
  • the sleeve has a rectangular, upright cross section like that Mandrel, so that horizontal displacements between components A and B are only possible in the longitudinal direction of the sleeve.
  • the sleeve is in FIG. 7 shows an oblique view of the sleeve shown in FIGS. 1 to 3, so with lateral scope.
  • the mandrel is a hollow profile. With large ones The length of the mandrel can be dispensed with a closure of the cavity, in the case of shorter or large mandrel cross sections, however, one is recommended Sealing cap on the protruding end of the mandrel that is not concreted in, so that the concrete cannot run out, but the spike largely is stiffened with concrete.
  • Figures 8 and 9 show an alternative design using a mandrel 11 with pressure distribution elements 12 and a sleeve 13 with pressure distribution elements 14. It is essential here that the pressure distribution elements do not have their own vertical rod sections, but that for this vertical edge regions 15e and 15f of the end plate 15 of the sleeve 13 are used become.
  • the end plate 15 has a slightly thicker in this case Wall thickness and is bent back at its four corners, so that Four tabs 15a to d are formed, which protrude almost horizontally into the component. The joint ends of the horizontal are at these four tabs Rod sections 14a to 14d welded.
  • bent tabs 15a to 15d could be dispensed with if the rod sections 14a to 14d forward to the end plate 15 extended, these extensions expediently on an arch pulls inward so that it is welded to the back of the end plate 15 can be.
  • mandrel 11 Exactly the same construction is used on mandrel 11.
  • the mandrel is given one here own end plate 16.
  • This end plate 16 has a central recess with the same contour as the mandrel, so that the latter along the recess can be welded to the end plate 16. Otherwise applies here for the pressure distribution elements the same as said for Figure 9.
  • Figures 10 to 12 show a third alternative consisting of one Mandrel 21 with additional pressure distribution elements 22 and a sleeve 23 with additional pressure distribution elements 24.
  • Exemplary embodiments are the pressure distribution elements laid twice and in such a way that the adjacent bars are next to each other run.
  • the advantage here is that the two horizontal Connectors 2g and 22g and the two horizontal connectors 2h and 22h of the mandrel as well as the horizontal connectors 4g 24 g and 4h and 24 h of the sleeve not in the same horizontal plane run, but each arranged approximately vertically to each other are the support surfaces effective for the application of force in the concrete to enlarge.
  • FIG. 13 shows a sleeve / mandrel connection similar to FIGS. 1 to 4, however, in concrete with the corresponding components A or B and the gap between them C. Because of the details may be referred to the previous figure description. On The only difference is that the horizontal bar sections 2a to 2d and 4a to 4d slightly bent towards the inside of the component are so easy to run on each other.
  • connection reinforcement of components A can also be seen in FIG and B consists of a stirrup reinforcement running perpendicular to the joint 17 and several rods 18 running parallel to the joint Bars 18 can be conveniently on the construction site transversely to their longitudinal extent in the space between the pressure distribution elements on the one hand and the mandrel or sleeve, on the other hand, need not be laboriously threaded lengthways. At most the pressure distribution elements have to be spread slightly to be sufficient Space for pushing the rods 18 is available put.
  • a stop 19 fastened to the mandrel This stop is used when the mandrel does not have its own end plate having; it ensures that the mandrel is not inserted too deeply into the sleeve is because he when the component A is boarded on the inside the formwork or the joint material is in contact.
  • Figure 14 shows a sleeve / mandrel connection similar to Figures 1 to 7; therefore, the same reference numerals are corresponding parts been used.
  • the difference according to the one described first Embodiment is that the pressure distribution elements not both above and below the sleeve / mandrel connection are arranged, but either only above or only below. So can be seen from the mandrel 1 that there the upper rod sections 2a and 2b have been omitted and only the rod sections 2c and 2d below of the thorn are present.
  • These two bar sections are like the first Embodiment at their ends facing the joint vertical connectors 2e 'and 2f' welded to the mandrel 1 while the opposite ends by the arc-shaped already described horizontal connector 2h are interconnected.
  • the pressure distribution elements are opposite, namely only provided above the sleeve. You can see the two roughly horizontally extending rod sections 4a and 4b, the ones facing the joint End each with a vertical connector 4e ' the face plate 5 are connected while the opposite ends again merge into one another via an arcuate connecting piece 4g.
  • the two approximately horizontal rod sections, their vertical and their horizontal connectors are as described in the opening paragraph Embodiment by turning one and the same Pressure distribution element manufactured.
  • FIG. 14 The design described in FIG. 14 is particularly advantageous Manufacturing costs because of the cost of materials for the pressure distribution elements is only half as high as that described at the beginning Embodiment. Surprisingly, it has been shown that there is hardly any reduction in the transferable forces. Apparently attach the pressure distribution elements to the top of the sleeve and the bottom of the mandrel the main load transmission relative to the associated Concrete components.
  • FIG. 15 A particularly favorable design is shown in FIG. 15. Corresponding to each other Parts have the same reference numerals as in Figures 9 and Designated 14.
  • this design differs in that the Sleeve 3 an end plate 15 similar to that used in Figure 9 here but only on one side of the tabs 15a and 15b in order to attach the rod sections 4a and 4b thereon Welding pressure distribution elements. This allows the Bar sections 4a and 4b can be dispensed with any turn.
  • Figure 15 is characterized in that the approximately horizontally extending rod sections 2c, 2d, 4a and 4b of the pressure distribution elements are arranged asymmetrically as in Figure 14, namely on mandrel 1 only below it and on sleeve 3 only above the same, and that the said rod sections are not at their ends need to be connected more.
  • rod sections 2a to 2d and 4a to 4d are not exactly horizontal, but rather at an angle or with additional bends.
  • the sleeve / mandrel connection according to the invention is distinguished due to the special course of the pressure distribution elements through high power transmission at low manufacturing costs.
