    Summary
    The invention relates to a device for receiving a formwork anchor (3) in a formwork element (1, 2) of a concrete wall formwork with a formwork-resistant insert pot (4) whose pot bottom (5) facing the inside of the formwork has a passage opening (6) for an anchor end (7, 8) which is held within the insert pot (4) in an anchor receptacle (9, 10) so as to be non-displaceable, and is described with a holder (12) for the anchor receptacle (9, 10) which is pivotably supported relative to the pot base (5). In order to ensure advantageous construction conditions, it is proposed that the armature receptacle (9, 10) is supported on the pot base (5) with the interposition of a sealing ring (11) sealingly enclosing the armature end (7, 8) and an annular groove (14) in the region of its support end. forms in which a flexible retaining ring (13) of the holder (12) engages.
    (Fig. 1) / 13 (41031) II
    The invention relates to a device for receiving a formwork anchor in a formwork element of a concrete wall formwork with a formwork-resistant insert pot, the pot bottom facing the formwork side has a passage opening for an anchor end, which is held in the anchor pot in a fixed manner, and with a holder for the anchored to a limited extent with respect to the base of the pot.
    The opposing formwork elements of a concrete wall formwork are held by formwork anchors at a distance determining the wall thickness, the formwork anchors penetrating the formwork elements and engaging on the outside of the formwork elements in nut threads of anchor receptacles on which the formwork elements are supported under a tensile load on the formwork anchors. So that the formwork elements on one side of the wall do not have to be accessible from the outside, the anchor receptacles associated with these formwork elements are arranged in form-proof insert pots, the bottom of the pan facing the inside of the formwork elements is penetrated by the anchor end, so that the threaded end of the anchor end passes through the pot bottom until it stops in the nut thread of the anchor receptacle can be screwed in, which is held in a rotationally fixed manner in relation to the insert pot. To take into account misalignments, the pot bottoms form ball sockets in which the anchor receptacles are pivotally supported to a limited extent (EP 2 816 175 A1), namely with spherical cap-shaped support ends. Such an embodiment has compared to another known construction (DE 10 2010 002 108 A1), in which a spherical cap-shaped support for the / 13
    Anchor receptacle is provided on the outside of the formwork element, the advantage that by supporting the anchor receptacle in the form of a ball joint, an otherwise necessary sealing of the anchor bushing by the formwork element can be omitted under certain circumstances if the ball joint is tight, but this requires precise machining. The design effort associated with the ball-joint-like support is therefore disadvantageous.
    The invention is therefore based on the object of designing a device for receiving a formwork anchor in a formwork element of a concrete wall formwork in such a way that a tensile and tight connection of the formwork anchor to the formwork element from the inside of the formwork is ensured with simple design requirements, and to compensate for any misalignment.
    Starting from a device of the type described at the outset, the invention achieves the object in that the anchor receptacle is supported on the pot base with the interposition of a sealing ring which tightly surrounds the anchor end and forms an annular groove in the region of its support end, into which a flexible retaining ring of the holder engages.
    Since the sealing ring tightly encloses the anchor end and is held under a prestress between the pot bottom and the supporting end of the anchor receptacle, a tight passage of the anchor end through the formwork element can be ensured in a simple manner without having to forego a simple compensation of misalignments. The storage of the anchor receptacle in the holder releasably connected to the insert pot by means of a flexible retaining ring which engages in an annular groove of the support end of the anchor receptacle allows, on all sides, limited pivoting of the anchor receptacle within the insert pot about pivot axes which run near the bottom of the pot and therefore only cause a slight transverse displacement of the anchor end within the passage opening in the bottom of the pot. This means that the sealing ring allows the / 13 to pass through even when the anchor receptacle swivels
    The end of the anchor can ensure through the pot base, especially since the reduction in the distance between the pot base and the support end of the anchor receptacle within the sealing ring that occurs when pivoting on one side of the pivot axis requires material displacement, which causes the sealing ring to rest against the pot base and at the support end of the anchor receptacle in the region of itself increasing distance supports. In this context, it should also be borne in mind that with a tensile load on the formwork anchor, the prestressing of the sealing ring increases and the sealing effect is thus improved. The anchor holder is supported by the sealing ring on the bottom of the pot.
    In order to control the deformation of the sealing ring when the anchor receptacle is pivoted within the insert top in the sense of a good sealing effect, the sealing ring can engage in a form-fitting manner in an end-side recess of the anchor receptacle and the recess has an outwardly sloping conical end face, which is due to the shape of the supporting end of the Anchor holder forces an advantageous deformation behavior of the sealing ring.
    The bracket for the anchor receptacle in the insert pot can be designed differently because it is only a matter of fixing the holder relative to the insert pot. Particularly simple handling conditions result, however, if the holder is held in the insert pot by means of a bayonet catch, because in this case the holder can be connected to the insert pot and removed from the insert pot together with the anchor receptacle held in the holding ring without the use of tools.
    An anchor receptacle according to the invention can be used both for anchoring an anchor end from the inside of the formwork element and for an anchor end passing through the insert pot, which is to be connected to the anchor receptacle in a non-displaceable manner from the outside of the formwork element. To anchor the anchor from the inside of the formwork element, the anchor receptacle can have a nut thread for the threaded anchor end, the support end of the anchor receptacle having a / 13
    Insert pot must cooperate rotary stop so that when screwing in the anchor end, the anchor receptacle forming the nut thread can not be rotated. At least one stop pin projecting radially beyond the armature receptacle and engaging with play in a radial pot recess can be provided as the rotary stop. The movement of such a stop pin in the pot recess is necessary to allow the anchor receptacle to pivot on all sides relative to the insert pot.
    The subject matter of the invention is shown in the drawing, for example. Show it
    1 a concrete wall formwork with a device according to the invention for receiving a formwork anchor in sections in the area of a formwork anchor in a schematic axial section,
    2 shows a device according to the invention in an axial section on a larger scale,
    Fig. 3 is an end view of the device according to the invention in the direction of arrow III of FIG. 1 on a larger scale and
    Fig. 4 is a section along the line IV-IV of Fig. 1, also on a larger scale.
    The concrete wall formwork according to FIG. 1 has formwork elements 1, 2 which are opposite one another and are connected to one another by formwork anchors 3. For this purpose, the formwork elements 1, 2 are provided with insert pots 4, the pot bases 5 of which form through openings 6 for the respective anchor ends 7, 8. These anchor ends 7, 8 are connected in a displaceable manner to anchor receptacles 9, 10, which are supported on the pot base 5 with the interposition of a sealing ring 11 and are held within the insert pot 4 by means of a holder 12, specifically by means of a flexible retaining rings 13 which are inserted into an annular groove 14 engages in the region of the support end of the anchor receptacles 9, 10 and is held by the holder 12 in contact with a bottom-side annular shoulder 15 of the insert pot 4, as can be seen in particular from FIG. 2. In contrast to the anchor receptacle 10, in which the anchor end 8 with the help of a / 13
    Locking ring 16 is held firmly in various axial positions relative to the anchor receptacle 10, the anchor receptacle 9 is provided with a nut thread 17 for a threaded portion of the anchor end 7, so that the formwork anchor 3 with its anchor end 7 from the inside of the formwork element 1 through the passage opening 6 in the pot bottom 5 can be screwed into the anchor receptacle 9 up to the stop. In order to hold the armature receptacle 9 in a rotationally fixed manner relative to the insert pot 4, the supporting end of the armature receptacle 9 forms a rotary stop in the form of stop pins 18 protruding radially above the supporting end, which engage in radial pot recesses 19 with play, as can be seen in FIG. 4.
    The bracket 12 for the anchor receptacles 9, 10 can be designed differently, because it is only important to fix these brackets 12 relative to the insert pot 4 accordingly. In this context, simple constructional relationships result if the holders 12 are detachably connected to the insert pot 4 by a bayonet lock 20. 2 and 3, this bayonet catch 20 has recesses 22 provided in a pot flange 21, from which receiving grooves 23 for retaining webs 24 on the sleeve-like holder 12 extend. The holder 12 can thus be axially inserted with their holding webs 24 into the recesses 22 of the pot flanges 21 and then rotated until the holding webs 24 engage in the receiving grooves 23, which are preferably provided with a run-on slope, and thereby the holder 12 against axial pulling out of the insert pot 4 hold tight.
    The support of the anchor receptacles 9, 10 on the pot base 5 of the insert pots 4 via a sealing ring 11, which lies tightly against the anchor end 7, allows a simple passage of the anchor end 7, 8 through the pot base 5, because the sealing ring 11 the gap seals between the pot bottom 5 and the supporting end of the anchor receptacles 9, 10, not only in the case of a coaxial arrangement of the insert pot 4 and formwork anchor 3, but also in the event of misalignments in which the circuit anchor 3 runs inclined relative to the insert pot 4, as shown in FIG 2 can be removed. With such a / 13
    Pivot position of the formwork anchor 3, the anchor receptacle 9, 10 must also be able to assume this pivot position, which is ensured by the flexible retaining ring 13. Because of the axial prestressing of the sealing ring 11, this sealing ring 11 remains in tight contact with both the pot base 5 and the supporting end of the anchor receptacles 9, 10 even when the gap between the pot base 5 and the support end of the anchor receptacles 5 is expanded 2 shows, the supporting end of the armature receptacles 9, 10 can be provided with an end recess 25 for the sealing ring 11, this recess 25 having an outwardly tapering end surface 26. The deformation of the sealing ring 11 caused by this shape of the recess 25 supports the tight contact of the sealing ring 11 on the pot bottom 5 on the one hand and on the supporting end of the anchor receptacles 9, 10 with an inclined course of the formwork anchor 3.
    To connect the two formwork elements 1, 2, the formwork anchors 3 can be screwed through the anchor receptacle 10 of the formwork element 2 into the anchor receptacle 9 of the formwork element 1 up to the stop. For this purpose, the locking ring 16 in the anchor receptacle 10 is pivoted from the drawn locking position, in which the locking ring 16 engages with locking ribs in annular grooves 27 of the anchor end 8, into a release position by means of a hand lever 28, in which the locking ribs prevent the passage of the formwork anchor 3 release through the anchor receptacle. With the choice of the respective locking engagement of the locking ring 16, the effective length of the formwork anchor 3 is predetermined and thus the respective wall thickness between the formwork elements 1 and 2 is determined.
