"Device for connecting baton reinforcing bars"

The innovation relates to a device for connecting two aligned concrete reinforcement ^ '- v ^ La at your: ends.

To create a butt joint that is resistant to tension and compression Different possibilities are known for two rebars. For this, however, appropriate preliminary work is usually to be done the rods, such as the application of threads, swelling of thread ends or the like. There is also Socket connections in which the two to be butted *, SMk> » connected by means of a clamp-like device Werder. * * ~ -.- from two divided in the longitudinal axis with special Sc> v / _, *. held together Half-shells. In any case, more or less careful maneuvers are required, to be able to connect two bars together *

The innovation is based on the task of creating a way to add two reinforcing bars regardless of their To be able to connect surface design safely and easily with one another in a tensile and pressure-resistant manner.

The innovation solves this task with two, encompassing the rod ends Shells of approximately semicircular cross-section, the

have a profiling on the inside and on the outside are designed sohwaoh conically sloping towards the ends, as well as by correspondingly gefojnute clamping rings, dis on the Shells can be pressed on from the outside. The profiling expediently consists of grooves, teeth or the like.

The inventive device initially has the advantage that regardless of whether the rods to be connected have a surface profile ation in the form of ribs or are smooth, they are securely connected because the Press the profiles located on the inside of the shells according to the innovation into the rod surface. This pressing in is effected by pushing on the clamping rings from the outside, which can be done easily with a blow of a hammer or with a so-called hydraulic pliers old achieved the success can be that the connecting sleeve does not slip even with a heavy load on the rods.

The subject of the innovation is described below based on the in the attached Drawing illustrated embodiment explained in more detail. The illustration shows a longitudinal section on the left through the connection device according to the innovation and on the right side a view with part of an associated one Rebar.

The connecting device consists of two shells 1 and 2, each of which encloses a reinforcing rod 3 at their ends except for two narrow, mutually opposite slots 4. The shells are provided on the inside with a profile 5, for example a corrugation, which should be as sharp as possible, i

The outside of the bowls are slightly conical towards the outside;

sloping design · On these wedge surfaces 6 there are clamping rings 7 f

can be pushed open from the outside, which press the profile 5 \ firmly onto the surface of the rod 3 when wedging.

Claims (2)

Protection claims: 1.) Device for connecting two aligned Betonbewehrungssti '■ at their ends, characterized by two shells (1,2) encompassing the rod ends of approximately semicircular cross-section, which have a profile (5) on the inside and to the store on the outside are slightly conically sloping (6) and are further characterized by two correspondingly shaped clamping rings (7) »which can be pressed onto the shells (1, 2) from the outside. 2.) Device according to claim 1, characterized in: that the profiling (5) from a grooving, toothing or the like. consists.
