The concrete structure to be delivered is followed by one concreting section after the other. The places where when concreting the previous Section the formwork elements were anchored, are used for attachment after they have been removed of consoles or other required parts for the next concreting section. In contrast to a conical one Part that is required when anchoring or tensioning the formwork, such as a so-called flow cone, becomes a fastening O 'element is referred to as "climbing cone" in climbing formwork. Such climbing cones exist in known designs made of steel throughout.

The aim of the invention is to provide a device of the type mentioned at the beginning which does justice to practical requirements particularly well Art can be created, which is also easy to handle and can be removed very easily after use. The invention strives for a cheap training. _; Such a device as a whole and in its details - on.

Koniöcher Mailtelfläche, by one in the outer body in the Area of its large end arranged ring body made of metal and by a detachably connectable to the inner body, a mounting element having a receptacle for the part to be attached. The ring body is advantageous here cup-shaped.

'Such a device is robust, enables easy \ and quick attachment of the desired elements to an anchor point and can also be very easily removed again, wherein the cooperating made of metal, in particular steel, existing ■ inner body and the outer body made of plastic advantageously . When turning the inner body to unscrew from the anchor thread, the outer body does not need to rotate in the surrounding concrete, so that there are no large frictional forces here, but a simple push in the axial direction takes place, pie device can safely absorb all forces occurring during use, with the im The ring body located on the outer body increases the load-bearing capacity. The device is particularly suitable as a so-called climbing cone, but can also be used with advantage for other fastening purposes.

The fastening element can be designed in various ways. In particular, the invention sees as a fastening element a threaded bolt, which has a head designed as a tool engagement and one between the head and a threaded area located support point for the to be attached

In the front part of the inner body 1 there is an internal thread 6) which is used for screwing onto a not shown thread end of an anchor seated within a recess in a concrete structure, the screw-in depth being limited by a pin 7 crossing the inner body 1. The internal thread 6 corresponds to the external thread of the anchor to which the device is to be attached «This can be a normal thread, a cord thread or a { . other thread '.

In addition, the inner body 1 is provided with a further internal thread 8, namely a cord thread, which is coaxial with the thread 6, but has a larger diameter than this and absorbs high transverse forces can.

The outer body 2 has an inner, the inner body x 1 in a cylindrical seat 9 receiving part 10 and a in this transitioning outer part 11, which has a conical lateral surface 12. In the embodiment shown, there are two Areas 12a and 12b with different conicity are present. The collar 4 of the inner body 1 has the same outside Conicity like area 12b. Between its two parts 10 and 11, the outer body 2 forms radially directed, in Longitudinal webs 13 (in the left half of Fig. 1 in section and in the right half in view, recognizable.

Outer part 11 of the outer body 2. In the thereby left Space is a cup-shaped ring body 14 made of steel a ^ · set, which rests against the end faces 13a of the webs 13 and at the same time an inner support and stiffening for the Outer body 2 represents in the area of this end. This is at the same time with the advantage of the plastic ^ outer body ensures a high load capacity of the device. A snap ring inserted into a circumferential groove 15 of the inner body 1 16 or the like. secures the position of the parts of the device and connects an axial displacement between inner and Outer body. The inner body 1 is, however, relative about its longitudinal axis L in the cylindrical seat 9 of the outer body 2 rotatable in relation to this, which makes it much easier to loosen the device after use.

In the embodiment shown, the fastening element is a bolt 17 with a thread 8 of the inner body 1 screw-in external thread 18, a hexagonal head 19 to which a tool can be attached, and with a between the head 19 and the threaded area 18 provided support point 20 for Ίβη part to be attached, for example for a console with an attachment that can be attached to the support point 20 of the bolt 17, an eyelet, opening or the like.
