Definitions
- the invention relates to a connecting sleeve for the end Connection to a reinforcement element of a concrete component, the end of the reinforcement element in the connecting sleeve protrudes and the space between the connecting sleeve and reinforcement element filled with a potting compound is.
- connecting sleeves are known as Castings are formed.
- the manufacturing effort for such parts is relatively high.
- Recesses are provided that are lined up in such a way that they form clamping surfaces, especially one on train create a resilient connection.
- the rod end is fixed by means of radially arranged adjusting screws aligned with the sleeve.
- the formation of this sleeve Cast steel is very expensive, especially the incorporation the recesses are correspondingly complex and complicated.
- German published patent application 1 559 509 discloses a sleeve for connecting the ends of two steel rods, wherein the inner surface of the sleeve with protrusions and depressions provided that can have the shape of ring grooves. rod ends and sleeve are potted with epoxy resin.
- the invention has set itself the task of a connecting sleeve as described at the beginning to provide the is as inexpensive to manufacture.
- the invention is based on a connecting sleeve as described at the beginning and suggests that the connecting sleeve is designed as a profile material section piece and the connection area on the inner wall of the Connection sleeve is designed as a thread.
- the proposal according to the invention turns away from the complex Production of individual castings and rather strikes before, for example tubular rod material, for example appropriate steel pipes, to be used in the desired Length and thus the basic body of the Form connection sleeve. It is easily possible through appropriate selection of the profile goods (steel quality, inside diameter, Wall thickness) the connecting sleeve the respective To optimally adapt the load.
- the profile goods are there available cheaply as a mass product, which ultimately with low production costs of the connecting sleeve at the same time very wide range of variants of the connecting sleeve for various applications. So it does it Invention that actually two contradictory features be combined.
- a high number of variants usually leads correspondingly high effort in the provision of appropriate Tools, molds and in the production of small Series.
- the proposal according to the invention already provides small series a cheap production for sure.
- the profile material is, for example, in a rolling or slide-pull process won.
- drawn tubes made of steel are characterized by small dimensional deviations and good surface quality out.
- This manufacturing process leads also usually to an increase in strength, which for the scope is also an advantage.
- profile material for example in a rolling process, such as pipes or the like be winning. If necessary, extrusion processes, of course depending on the material, be used.
- the main advantage of the invention lies precisely in the fact that this profile material is very cheap in various dimensions such as inner diameter, wall thickness or outside diameter is available and so one high variety of types allowed without a large number of different ones Having to keep molds.
- a thread incorporated In the cut from the profile material, for example sawn off, cut or cut, profile material section piece is then in a further processing step a thread incorporated. Cutting the thread This is done, for example, with appropriate machines fully automatic, which keeps costs down. At the same time but it is possible to thread the inner surface of the profile material to be roughened so that the liquid to be poured in Potting compound, which is the forces between the reinforcement element and has to transfer the connecting sleeve, really positive einkrallt. It is not a mandatory requirement that the inner wall of the coupling sleeve on its entire Inner wall surface carries a thread, this can only in Connection area or in a part thereof, which then as Connection area acts, be provided.
- the proposal according to the invention combines low manufacturing costs with a high variability in design the connecting sleeve according to the invention and represents a very reliable technology for connecting the reinforcement element available with the connecting sleeve.
- the invention is not limited to the connecting sleeve as described, but also includes a Method for producing such a connecting sleeve, wherein first of all a profile material section piece severed, for example sawn off, tapped or cut off and then in the inner wall of an interior of the A thread is cut into the profile material section piece.
- the profile material section piece is made of a profile material obtained by parting off, cutting off or sawing off, in particular the cutting off or parting off with appropriate tools very quickly and inexpensively he follows.
- the reinforcement element carries ribs and the ratio from threads to ribs in the in the connecting sleeve protruding area of the reinforcement element 2.5 to 5, preferably Is 2.9 to 4.2. It's cheap if not just one non-positive, but as positive a connection as possible between the connecting sleeve and the reinforcement element, for example the reinforcing steel. This is done on the reinforcement element or the reinforcing steel ribs provided, through which there is a positive connection in the casting compound or the concrete (depending on the application). It did result in a relatively higher number of threads, that is, grooves in the inner wall, the bond between the Reinforcement element and the socket considerably improve.
- the depth of the threads is less than the radial, especially the middle width of the space.
- the gap is between the coupling sleeve and the reinforcement element forming sleeve-like bodies.
- it is the reinforcement element or the reinforcing steel concentric into the sleeve-like or cylinder-like connecting sleeves introduced. It would then become a "sleeve" of the space with constant thickness. This is the following understood as the mean radial width of the space.
- Such an arrangement is, in particular, by the below Centering devices still explained aimed at a force application of the reinforcement element as uniform as possible to reach over the casting compound in the connecting sleeve.
- the mean radial width of the gap between 1 and 6 mm, preferably between 2 and 4.5 mm is.
- the mean radial width can also match the game Correspond to the arrangement of the reinforcement element in the connecting sleeve.
- a certain amount of play is required to insert the reinforcement element advantageous in the connecting sleeve, being relatively large width of the gap (of the game) also with relatively thick reinforcement elements are used.
- the connecting sleeve according to the invention is particularly distinguished characterized by the fact that a permanent Slip between the connecting sleeve and the one with the potting compound connected reinforcement element of less than 0.1 mm formed.
- a permanent Slip between the connecting sleeve and the one with the potting compound connected reinforcement element of less than 0.1 mm formed is particularly characterized achieved that the interaction of the reinforcing element, the Potting agent and the connecting sleeve optimized accordingly becomes.
- this is achieved in that the geometry is chosen such that the radial width of the space is as low as possible.
- the connecting sleeve with the in potting compound, especially resin or epoxy resin, embedded reinforcement element designed as reinforcing steel has the same fatigue strength as the unimpeded one Rebar.
- the use of reactive resin adhesives as a potting agent the fatigue strength is considerable increased, with a small slip at the same time over the entire connection under the working load of no more than 0.1 mm.
- the selected arrangement achieves further surprising benefits. In addition to the one described above cheap production with a wide variability vibration-resistant connection, and only a slight slip provided according to the invention.
- the anchoring depth of the in the connecting sleeve existing reinforcement element or reinforcing steel at least 5 times the diameter of the reinforcement element or corresponds to the reinforcing steel diameter.
- the anchorage depth at least 5 to 10 times, especially within the Interval from 6.5 to 9 times the diameter of the reinforcement element / the reinforcing steel diameter.
- the anchoring depth is somewhat greater fails than with larger rod diameters, with one Bar diameter of about 8 to 16 mm advantageously found that there was at least a factor of 8 between the anchoring depth and the rod diameter, whereas in the case of rebars between 20 and 32, 36 or 40 mm in diameter possibly already a factor of at least 7 between the Anchorage depth and the diameter is sufficient.
- an internal thread also offers several additional advantages. On the one hand, it is possible for the thread to Screw in a bolt or the like with a suitable one External thread is used. Furthermore, the internal thread serves also the power transmission between the reinforcement element (for example a rebar or reinforcing bar) over the To improve adhesive mortar on the connecting sleeve. The stake the thread is therefore twice as cheap.
- the invention Proposal does not limit the joint to just one Connecting with another element using adhesive mortar, but also allows the screwing in of a bolt with the corresponding External thread. It can therefore also be different Systems of reinforcement elements using an appropriate nevertheless acting as an interface connecting sleeve without any problems be connected to each other.
- a grout is the grout equate.
- the grout can be used (optionally based on cement) also resins, epoxy resins or Reaction resin adhesive can be used, on the one hand, quickly set, are resilient after a short time and also a high Able to transfer the workload.
- connection sleeve end carries an internal thread. It has been found that with such a configuration, sufficient power transmission from the reinforcement element (or rebar) the connecting sleeve is reached. The effort for cutting the thread can therefore be reduced accordingly without the benefit of the connection option, especially in the end area of the connecting sleeve.
- Mounting plate possibly made of plastic, in the Screw in thread. The plastic does not need a pre-cut Have threads, the softer plastic material yields accordingly.
- the Internal thread extends over the entire length of the connecting sleeve.
- the invention is not limited to the pure connection of reinforcement elements that corresponding to their joint are connecting. In principle, it is also possible to use the connecting sleeve to be dimensioned so that these multiple reinforcement elements receives.
- the connecting sleeve with the is essentially constant cross-section.
- corresponding Seals are provided. Such an arrangement allows an appropriate, secure measure of Internal thread is available for connection purposes.
- the connecting sleeve is constricted at the end is that the reinforcement element is still insertable.
- the constriction can do just that be dimensioned so that when the reinforcing bar is in the reinforcing element the remaining gap is so small that no adhesive mortar flows out.
- this can Constriction also conveniently as a centering device for The reinforcing bar is used to ensure that the reinforcing bar as concentric as possible for optimal power transmission between the reinforcement element and the connecting sleeve is arranged.
- the constriction is obtained in a simple manner. This is, for example, by appropriate pressing or pressing of the end area of the connecting sleeve possible.
- the internal thread can be reached in front of or be cut after pressing. It is actually there possible, also the internal thread in the constriction area, for Example for putting on a plastic mounting plate or the like to use. But it is also possible without any problems just re-cut the end of the joint, if there is a correspondingly accurate internal thread, for example for the Screwing in a bolt and so on.
- there the area of constriction also helps with statics, because the shear forces that occur also on the Support the constriction area. With a corresponding Dimensioning results in higher load capacities, or the thread can be shorter for load entry or omitted.
- the connecting sleeve advantageously has different openings on.
- one or more fill openings provided for the adhesive mortar in which the adhesive mortar then is introduced when the reinforcement elements respectively Reinforcement bars positioned accordingly in the connecting sleeve are.
- the adhesive mortar is preferably pressed in with pressure. The aim is that the adhesive mortar is as possible without the formation of cavities and so on in the gap spreads between reinforcement element and connecting sleeve.
- one or more vents provided in the connecting sleeve.
- the filling opening is preferably located in the middle or in the middle area of the connecting sleeve, um spreading the adhesive mortar as symmetrically as possible in the To reach sleeve.
- the ventilation openings are located preferably in the end area of the connecting sleeve.
- a sealing ring or a sealing cord to be provided as a seal.
- the sealing ring is opened, for example the reinforcement element designed as a reinforcement bar at the end pushed on and clamped on this.
- a sealing cord in the gap between the reinforcing bar and insert the connecting sleeve.
- the Seal arranged in the connecting sleeve and covers the Gap between the connecting sleeve and the reinforcement element.
- sealing cap Seal provided, with the sealing cap on the connecting sleeves can be put on with a clamp.
- connection of the sealing cap on the connecting sleeve it is also possible that the connecting sleeve end a corresponding thread or a Has undercut, which with the sealing cap in appropriate (thread or protruding nose) holding It is also advantageous to remove the seal if necessary to form several elements that together form a complete Sealing result. Especially with relatively poorly accessible Connections is an interesting option.
- the sealing ring can also be used to center the reinforcing bar serve in the sleeve what the quality of the force transmission and thus improves resilience.
- the end constriction (or compression) of the connecting sleeve acts as a seal.
- the constriction at the end reduces the Gap between the connecting sleeve and the reinforcement element, which can be dimensioned so that the remaining Gap that still exists for the insertion of the reinforcement element, is so small that no noteworthy adhesive mortar material flows out. If an appropriately quick-setting adhesive mortar is used, this will automatically make this gap close. If necessary, it is also possible to use a slightly yielding tape or adhesive tape inside the Glue constriction, which when inserting the reinforcement element is compressed accordingly, but the remaining gap securely closed.
- the seal with the internal thread the coupling sleeve interacts to hold one secure arrangement of the seal in the area of interest to obtain.
- the design of the seal also allows that this is designed as an assembly plate, whereby the Assembly, for example within the formwork when creating the Concrete component is made easier.
- the seal doubly used because in addition to the actual function, the gap to seal, this serves as an assembly plate and facilitates the Assembly.
- a boundary piece is arranged in the connecting sleeves. The limiting piece is used for the connecting sleeve if possible centered over the two intermittently To place reinforcement elements. It therefore limits the Possibility of how far a reinforcement element end in the sleeve dips.
- the boundary piece arranged in the middle but not limited to this. It is also possible, corresponding asymmetrical arrangements of the limiting piece to choose. It is provided if one Constriction is arranged on the end side of the connecting sleeve is the limit piece before pressing the connecting sleeve end install.
- the restriction piece is used as a plug trained, this essentially the Cross-section of the inside diameter of the connecting sleeve closes. This makes it possible to avoid the adhesive mortar flows into the area behind the stopper.
- the thread at the connecting sleeve end for example for screwing in a bolt, should remain clean and accessible.
- a as a limiting piece Split pin insertable through a hole can be used in the connecting sleeve.
- this split pin is the front end of a mixing nozzle the cartridge for filling in the adhesive mortar and the cartridge is insertable into the respective opening to the adhesive mortar fill. This ensures that a split pin is available because it forms the front part of the nozzle and is simply broken off at a predetermined breaking point and remains in the connecting sleeve.
- FIG. 1 Another is according to the invention Variant provided that several, preferably as a centering device three resiliently arranged circumferentially equidistant Serve plastic pins.
- the pins are so compliant that they are in a corresponding opening in the connecting sleeve indented, but there are stable to one to achieve safe centering.
- the advantage with this Variant is that on cutting a thread can be dispensed with in the connecting sleeve.
- Alternative is it is of course possible to provide the thread and the plastic to move so that the thread yields accordingly and the thread cuts into the plastic.
- the limiting piece in the middle Has receptacle for the reinforcement element and so as a centering device mitdient.
- the limit piece a conical or frustoconical recess, which is also a stepless adjustment to different diameters of the reinforcement element allowed.
- the seal or the constriction also serves as a centering device. This ensures that the sleeve along two areas, namely in the middle and in the End area, can be oriented concentrically to the connecting sleeve.
- the arrangement of the constriction as already mentioned at the beginning described results in additional synergetic effects.
- an adhesive mortar is provided as grout.
- adhesive mortars consist of a mixture of Cements, various plastics and other additives.
- the adhesive mortars use special synthetic resin dispersion powder etc. added.
- the grout or the Adhesive mortar should favorably have the following properties exhibit. It is said to have a high compressive strength at the same time have good fluidity. Through good fluidity a full-space pressing of the interior of the connecting sleeve reached. A high early strength is favorable, in order to be short after casting a certain partial load on the connecting sleeve to reach.
