Definitions
- the invention relates to a sleeve anchor for concrete parts, consisting of a stop sleeve with an internal thread and an anchor shaft with integrally formed anchor foot, the Anchor shaft with its connection end facing away from the anchor foot protrudes into a connecting section of the stop sleeve, the one with the internally threaded connection end is radially pressed.
- Such sleeve anchors serve as transport anchors Striking concrete parts, especially precast concrete parts, on hoists and transport equipment.
- the sleeve anchor are embedded in the manufacture of the concrete parts so that the Stop sleeve is accessible from the outside.
- the stop sleeve can be, for example, with an anchor head or a wire rope loop of connected threaded pins be screwed in to lift and close the concrete part transport.
- a known sleeve anchor In a known sleeve anchor, it is made of a smooth, Anchor shaft manufactured on its cylindrical rod Provide a connecting thread with an external thread that fits into the with continuous internal thread stop sleeve is screwed in. This screw connection is through a radial compression at a peripheral point of the connecting section the stop sleeve secured.
- the making of this Sleeve anchor with screwed-on stop sleeve is proportional expensive because the connection end of the anchor shaft must be provided with the external thread.
- the Transition from this external thread to the smooth section of the Anchorage is inevitably a weak point.
- a known sleeve anchor of the type mentioned Genus (DE-A-33 12 458) consists of the anchor shaft Reinforced rebar.
- the connecting portion of the stop sleeve is designed with a cylindrical inner wall without thread and is through with the connection end of the anchor shaft Pressing connected.
- the deformed one encloses Connection section of the stop sleeve with ribs provided outer contour of the anchor shaft.
- the through the ribs of the anchor shaft caused material weaknesses in the Place the area of the connecting section of the stop sleeve with the intended tensile stress on the sleeve anchor Weaknesses represent the permissible resilience limit.
- An increase in the permissible load capacity can only by choosing a larger anchor shaft diameter and thus also the stop sleeve can be reached.
- DE-U-87 05 508 there are several sleeve anchors different ways to connect one with Internal threaded stop sleeve with an anchor shaft shown.
- a welded connection Fig. 4
- a sleeve anchor of the type mentioned at the beginning Fig. 2
- the stop sleeve by radial pressing with the ribbed one Connection end of the anchor shaft is connected.
- the ribs of the anchor shaft cause tensile stress an expansion of the anchor sleeve, which increases the resilience of the Sleeve anchor is limited.
- the object of the invention is therefore a sleeve anchor train the type mentioned so that with simple manufacturing measures a highly resilient Connection of the stop sleeve to the anchor shaft reached becomes.
- connection end of the anchor shaft is created at the connection end a thread-like surface due to permanent deformation, which is adapted to the pressed internal thread. It understands themselves that the internal thread of the stop sleeve when radial Compression is also subject to deformation.
- the Thread tips of the individual threads are rounded off, so that in the connection area in the pressed state two Interlock threads with rounded tips and below that generated by the forming process radial bias. This creates a form-fitting, heavy-duty connection of the originally smooth cylindrical Anchor shaft reached with the stop sleeve, whereby due to the thread shapes that arise during the deformation a notch effect that reduces the resilience as far as possible is avoided.
- the permissible load capacity of the sleeve anchor obtained in this way is comparatively high, so that while maintaining the A larger shaft diameter and thread diameter Load level than with conventional comparable sleeve anchors can be achieved.
- the sleeve anchor shown in the drawing is for this determined to be embedded in a concrete part.
- the Sleeve anchor has a stop sleeve 1 that with Internal thread 2 is provided.
- the surface of the anchor shaft 3 is on one End with an anchor base 4 Mistake.
- the stop sleeve 1 consists of softer Material as the anchor shaft 3; nevertheless the cylindrical surface of the anchor shaft 3 through the pressed internal thread 2 deformed.
