Definitions
- the invention relates to a screw sleeve connection - primarily for reinforcing bars - as described in the preamble of claim 1.
- the sleeves of the known screw sleeve connections are cylindrical or have a hexagonal cross-section over their entire length with a constant contour.
- Tension rod sleeves which have conical chamfers at their ends. These have the purpose in the likewise conically widening, the sleeve shape adapted cladding tubes to cause a flow of the pressing orifice as evenly as possible during the pressing.
- the design of the sleeve according to the invention is intended to reduce this slip and also to increase the static and dynamic load-bearing capacity of the rod connection.
- a progressively increasing contour of the sleeve which corresponds to a progressive growth of the sleeve cross-section, is designed according to the force input from the rod into the sleeve, and the sleeve becomes increasingly deformable towards its end and expands to the end thread thread when it is unscrewed.
- the entire conical thread area is non-positively spanned by the sleeve, the slip is significantly reduced and the static and dynamic load-bearing capacity of the sleeve connection is increased.
- the generatrix of the contour of the sleeve that grows progressively outwards from the end of the sleeve can be, for example, parabolic, hyperbolic, exponential, sinusoidal or polygonal.
- the sleeve is provided with chamfers at both ends of the bore.
- REPLACEMENTB prevent stress peaks in the subsequent bars, which arise in the case of sharp-edged inner sleeve ends and reduce the fatigue strength.
- the chamfers are expediently given a linear or a curved contour which grows inwards from the sleeve end degressively.
- the sleeve is given a length such as to protect against radial tearing of the sleeve ends by an undesired exceeding of the torque specified for screwing the rod ends into the sleeve, such that after the rod ends have been screwed into the sleeve in accordance with the regulations There is still a small gap between the end faces of the rod ends. This space is dimensioned so large that when the permissible torque is exceeded when the sleeve is screwed on, the rod ends are countered. This prevents the rod end from being screwed into the socket in an impermissible manner.
- FIG. 1 shows a longitudinal section through a sleeve according to the invention.
- FIG. 2 shows a longitudinal section through a sleeve connection according to the invention with the sleeve deformed by screwing in the rod ends.
- the sleeve 1 provided according to the invention with an internal thread 2 has a contour which grows progressively towards the middle of the sleeve at the two end regions 3.
- the sleeve ends are provided with chamfers 4 on the inside.
- REPLACEMENT LEAF Figure 2 shows the complete socket connection.
- the rod ends 5/1 and 5/2 with rod end thread 6 and tapered thread end region 7 are screwed into the socket 1 up to the thread end 8.
- the end regions 3, which are weakened in relation to the central sleeve cross section by a progressively increasing contour, have deformed and expanded in accordance with the thread profile of the rod ends.
- an intermediate space 10 the width of which can become zero if the prescribed torque is exceeded.
- the width of the intermediate space 10 limits the ring rotation of the sleeve end which is open at the factory when the connecting rod is mounted with an inadmissibly high screwing torque to a dimension which prevents the sleeve from tearing open.
