    Description: The invention relates to a closing element in the form of a sealing plug for closing an anchor hole in a concrete wall.
    In the production of a concrete wall with so-called in-situ concrete formwork is usually provided on both sides of the wall to be produced. This is called a double-sided formwork. The concrete pressure that occurs when casting the concrete into the double-sided formwork, which bears on both formwork, is absorbed by formwork anchors. The formwork anchors are usually installed in ducts to allow reuse of formwork anchors. The ducts are usually cylindrical and remain in the concrete. With one-sided anchoring, which usually takes place with conical formwork anchors, usually no cladding tube is used. After drying or hardening of the concrete, the formwork anchor is removed so that an anchor hole remains in the concrete wall. The anchor hole may be conical in one-sided anchoring.
    The anchor holes described are sealed with sealing plugs. In many cases, special demands are made on the tightness of the sealing plug, for example in pools or the like.
    From DE 20 2009 018 645 U1 a sealing plug for closing anchor holes has become known, which consists of an elastomer. The known sealing plug is pushed in the direction of its longitudinal axis in the anchor hole. As a result, however, no permanent watertight closure of the anchor hole can be achieved at high applied water pressures.
    Furthermore, from DE 278 370 A1 a waterproof Schalungsankerdurchlass has become known, in which the sealing takes place by means of a spreading disc and mortar. In this case, after the insertion of the spreader in the anchor hole, the spreader is widened with a punch, so that the spreader is driven into the concrete of the concrete wall. However, this requires removal of the cladding tube. Furthermore, the spreading of the spreading disc damages the concrete wall.
    Further, in construction technology for a long time a sealing plug for closing anchor holes is known, which consists of a flexible sealing ring, which is penetrated by a screw, wherein the screw is countered by a nut. By turning the screw, the sealing ring is pressed in the longitudinal direction of the screw between a screw head of the screw and the nut. As a result, the sealing ring is widened radially to the longitudinal direction of the screw. The disadvantage here, however, is that the sealing ring is twisted when turning the screw relative to the nut. Over time, the sealing ring twisted back in the anchor hole (retorsion) and thus loses tension and tightness.
    Said sealing plug are also known from DE 10 2013 206 576 A1.
    Furthermore, DE 36 27 627 A1 discloses an injection packer for the injection of liquid substances, in particular plastics, by a hole introduced into a damaged concrete body.
    A packer for sealing boreholes in walls or the like is further known from DE 86 00 358 U1, DE 88 00 265 U1, DE 94 14 703 U1 and EP 0 642 620 B1. Finally, US 2009/0025328 A1 discloses a sealing plug in which an elastic plastic body is pressed together between two nuts in the direction of the longitudinal axis of the sealing plug and thereby radially expanded.
    In the known from the prior art mechanically sealing sealing plug thus a substantially cylindrical, soft sealing body is pressed in the axial direction to achieve a radial expansion.
    The sealing of anchor holes according to the prior art is always associated with large and therefore costly workload.
    In an anchor hole with a large inner diameter of the sealing body must be strongly pressed axially, so only seals over a short axial length. This reduces the sealing effect, in particular in the case of a large axial length of the anchor hole. If a good seal is to be made over a large axial length, further sealing plugs with larger diameters must therefore be provided when using sealing plugs according to the prior art. If conical anchors are used, as is customary, for example, in the so-called one-sided anchorage, then the anchor hole has differently sized inner diameters at its two ends. Again, sealing plugs of different diameters are required in the prior art for reliable sealing.
    Object of the present invention is in contrast to allow a structurally particularly simple design sealing plug for sealing a plurality of anchor holes with different inner diameters and / or conical diameter profile, the sealing plug over a large axial length seals and mounted with little effort can.
    This object is achieved by a sealing plug according to claim 1. The dependent claims give preferred developments again.
    The object of the invention is thus achieved by a sealing plug for closing an anchor hole in a concrete wall, wherein the sealing plug in the axial longitudinal direction with its first axial end can be driven forward into the anchor hole and wherein the sealing plug has at least before installation in the anchor hole following [0016] a) a sealing jacket extending in the axial longitudinal direction, which is formed at least partially from an elastomeric material; B) extending in the longitudinal direction of the sealing plug Einschlagkern which is received radially at least with its first axial end in the sealing jacket, wherein the impact core of a second axial end of the sealing plug, which is opposite the first axial end of the sealing plug, accessible wherein the impact core is formed of a harder material than the sealing jacket and radially stiff; Wherein the outer diameter of the sealing jacket at least partially increases from the first axial end of the sealing plug to the second axial end of the sealing plug, so that the sealing jacket extends at least partially axially when inserting the sealing plug into the anchor hole and axially reduces the outer diameter of the sealing jacket in at least one axial section becomes.
    The solution according to the invention is thus based on a sealing plug, which is formed at least in two parts: An impact core is at least partially inserted into a sealing jacket. The sealing jacket is at least partially formed of an elastomeric material. The first axial end of the sealing skirt, which preferably corresponds to the first axial end of the sealing plug, is inserted into the anchor hole for sealing an anchor hole. The sealing jacket can be molded or glued to the impact core.
    In the context of the present invention is understood by "radially stiff a material that can not be compressed in the radial direction as a spring element. The impact core is preferably at least partially bolt-and / or sleeve-shaped.
    In the context of the present invention, "axial" is understood to mean an axis parallel to the longitudinal axis or on the longitudinal axis.
    The first axial end of the impact core is radially, and in particular also axially, received in the sealing jacket, d. H. a part of the sealing jacket is formed radially to the first end of the wrapping core. The second end of the turning core opposite the first axial end of the turning core is freely accessible from outside the anchor hole. The second axial end of the impact core can thereby be acted upon directly by a hammer and / or indirectly via a plunger with a thrust force to drive the sealing plug into the anchor hole.
    Since the sealing jacket in the region of its second axial end which is opposite to the first axial end of the sealing jacket, thickened, the sealing plug initially stuck in the region of the second axial end of the sealing jacket in the anchor hole, so that the sealing jacket by further blows on the Impact core axially stretched and narrowed radially.
    If the sealing plug driven far enough into the anchor hole and the shocks are terminated on the impact core, so the sealing jacket tries to relax axially, d. H. To shorten. At the same time, the sealing jacket tries to relax radially again, in particular in the region of its second axial end. H. to increase its outer diameter. As a result, the sealing plug according to the invention achieves a very good, permanent sealing fit ("pressure") in the anchor hole.
    The sealing plug according to the invention is preferably designed to allow the closure of an anchor hole with different diameters.
    The elastomeric material of the sealing jacket is preferably an elastomeric plastic. The sealing jacket is preferably constructed entirely of an elastomeric material for the purpose of constructive and production-related simplification. If the sealing jacket is made of plastic, it is preferably molded onto the impact core.
    The impact core may be at least partially, in particular completely, sleeve-shaped in the axial longitudinal direction of the sealing plug.
    Preferably, the turning core is at least partially, in particular completely, rod-shaped in the axial longitudinal direction of the sealing plug, so that a reliable propulsion of the sealing plug is ensured in the anchor hole when driving the sealing plug.
    In a particularly preferred embodiment, the impact core of metal, in particular steel, is formed.
    In order to achieve an immediate propulsion of the sealing plug already at the first impact on the impact core, the impact core can rest with its first axial end at least partially on the sealing jacket. Preferably, the impact core lies with its first axial end, d. H. with its first axial end, completely on the sealing jacket. The first axial end may be formed flat or curved.
    Particularly preferably takes the outer diameter of the sealing jacket from an axial first end of the sealing jacket, which is inserted into the anchor hole ahead, to a first axial end opposite the second axial end of the sealing jacket conically.
    The outer diameter of the sealing jacket preferably increases steadily. Such a step-free outer diameter enlargement of the sealing jacket achieves a particularly secure and reliable sealing seat.
    The outer diameter or the lateral surface of the sealing jacket in the region of the first axial end is preferably more conical than in the region of the second axial end. In other words, the sealing jacket is slightly sharpened in the region of its first axial end or has a chamfer in order to simplify the insertion of the sealing plug into the anchor hole.
    The production of the sealing plug is greatly facilitated and its density significantly increased when the sealing jacket rests directly on the impact core.
    In a further preferred embodiment of the invention, the sealing jacket is axially closed at its first axial end.
    The sealing plug may have an end cap arranged on the impact core and / or on the second end of the sealing jacket, which is preferably mounted in the anchor hole after the sealing plug has been inserted. The end cap is preferably arranged in the region of a second axial end of the Einschlagkerns, which is opposite to the first axial end of the Einschlagkerns. Through the end cap, the fire-retardant effect of the sealing plug can be significantly increased. The end cap is preferably fixed by means of a thread on the impact core. The end cap can also be mounted by means of press fit or positive locking by undercut on the turning core or in the sealing jacket.
    More preferably, the sealing jacket is formed of a closed-cell foam. The closed-cell foam on the one hand allows a certain elasticity with significantly less twisting compared to rubber. The closed pores prevent axial passage of liquids and gases through the sealing jacket.
    In a particularly preferred embodiment of the invention, the sealing jacket is made of polyurethane. As a result, the refractoriness of the sealing plug can be significantly increased.
    In order to enable a uniform distribution of the radial forces on the sealing plug and a simple production of the sealing plug, the sealing jacket is preferably formed axially symmetrical.
    The sealing jacket is in particular rotationally symmetrical to the longitudinal axis of the sealing plug. More preferably, the entire sealing plug is axially symmetrical, in particular rotationally symmetrical, formed to the longitudinal axis of the sealing plug.
    Preferably, the sealing plug only has the sealing jacket and the impact core. Alternatively, the sealing plug preferably has only the sealing jacket, the insert core and an end cap. Through this reduction in the number of components, the sealing plug can be made particularly cost-effective and at the same time be made very robust.
    The invention further relates to a closure assembly with a concrete wall, in which an anchor hole is formed, wherein in the anchor hole a previously described sealing plug is arranged. The sealing plug was inserted in a direction of insertion into the anchor hole.
    Further features and advantages of the invention will become apparent from the following detailed description of several embodiments of the invention, from the claims and with reference to the figures of the drawing showing essential to the invention details.
    The features shown in the drawing are shown such that the features of the invention can be made clearly visible. The various features may be implemented individually for themselves or for a plurality of combinations in variants of the invention.
    FIG. 1a is a perspective view of a first sealing plug; FIG. FIG. 1b shows a side view of the first sealing plug according to FIG. 1a; FIG. Fig. 1c is a sectional view of the first sealing plug according to FIGS. 1a and 1b, wherein the first sealing plug is partially inserted into an anchor hole; Fig. 1d is a sectional view of the first sealing plug of Figure 1c after the reindeer in the anchor hole. FIG. 2 is a sectional view of a second sealing plug; FIG. and Fig. 3 is a sectional view of a third sealing plug.
    1a shows a first sealing plug 10. The first sealing plug 10 is rotationally symmetrical to its longitudinal axis 11 is formed. The first sealing plug 10 has a sealing jacket 12 and a wrapping core 14. The sealing jacket 12 is in one piece, d. H. integrally formed. Likewise, the impact core 14 is integrally formed. The sealing jacket 12 is formed of closed-cell polyurethane. The impact core 14 is solid made of steel.
    Fig. 1b shows the first sealing plug 10 in side view. From Fig. 1b it can be seen that the first sealing jacket 12 has a first axial end 15 and a second axial end 16. The sealing jacket 12 has a conical lateral surface 18 whose outside diameter increases from the first axial end 15 of the sealing jacket 12 to the second axial end 16 of the sealing jacket 12.
    Fig. 1c shows the first sealing plug 10 after it has been partially inserted into an anchor hole 20 of a concrete wall 22, but has not been applied with a force. The sealing jacket 12 has its axial length L0 prior to installation in the anchor hole 20. In the region of its second axial end 16, the sealing jacket 12 has its maximum outer diameter D0 - also before installation in the anchor hole 20 - on.
    From Fig. 1c it can be seen that the first sealing plug 10 is inserted with its first axial end 24 first in the anchor hole 20. The first axial end 24 of the sealing plug 10 corresponds to the first axial end 15 of the sealing jacket 12.
    The impact core 14 has a first axial end 26, which is surrounded axially and radially by the sealing jacket 12. The impactor core 14 also has a second axial end 28 opposite the first axial end 26, d. H. is axially opposite to the first axial end 26 of the Einschlagkerns 14. The second axial end 28 of the impact core 14 is in the form of a striking surface for a hammer (not shown). The second axial end 28 of the impact core 14 corresponds to the second axial end 29 of the sealing plug 10.
    Fig. 1d shows the first sealing plug 10 after installation in the anchor hole 20. For introducing the sealing plug 10 in the anchor hole 20 of the first sealing plug 10 by impacts on the second axial end 28 (in Fig. 1d by an arrow 30th indicated) in the anchor hole 20 driven. The axial length of the impact core 14 remains virtually unchanged. However, the sealing jacket 12 is axially stretched during the impact of the sealing plug 10 in the anchor hole 20. The sealing jacket 12 has the largest outer circumference in the region of its second axial end 16 and therefore initially remains stuck in the anchor hole 20 in this area. Further impacts on the second axial end 28 of the Einschlagkerns 14 then cause both an axial extension of the sealing jacket 12 to an axial length L1 and a radial narrowing to the diameter D ^ corresponds to the diameter of the anchor hole 20. In other words, the sealing jacket 12 is both axially stretched and radially compressed during insertion into the anchor hole 20. The first sealing plug 10 is thereby endeavored to restore its shape prior to installation in the anchor hole 20, d. H. its diameter D0 (see Fig. 1c) and its axial length L0 (see Fig. 1c) to take. The first sealing plug 10 is thereby pressed radially sealing in the anchor hole 20 for a long time, without causing a twisting or retorting of the first sealing plug 10 in the anchor hole 20. In other words, the sealing plug 10 is not twisted during installation, so that it does not come to a retorting.
    For further sealing of the anchor hole 20 and / or for covering the anchor hole 20, the first sealing plug 10 may have an end cap 32 (shown in dashed lines in Fig. 1d). The end cap 32 can be pushed onto the wrapping core 12. In this case, the radial outer surface of the Einschlagkerns 12 in the region of contact with the end cap 32 grooves and / or protrusions (not shown), in order to achieve a firm connection of the end cap 32 and Einschlagkern 14. Alternatively or additionally, the first sealing plug 10 may have a threaded connection (not shown) between the end cap 32 and the impact core 14.
    Fig. 2 shows a second sealing plug 10, which differs from the first sealing plug 10 according to FIGS. 1a-1d differs in that a turning core 14, although partially radially applied directly to a sealing jacket 12, but axially spaced from the sealing jacket 12 is formed. The axial distance of the impact core 14 to the sealing jacket 12 can be reduced during the assembly of the sealing plug 10.
    FIG. 3 shows a third sealing plug 10. In this variant of the sealing plug 10, the impact core 14 is completely accommodated in the sealing jacket 12. The second axial end 28 of the impact core 14 is accessible by a plunger (not shown) or a similar tool for driving the third sealing plug 10 in an anchor hole (see .An anchor hole 20 according to Figures 1c and 1d). The sealing jacket 12 has the second axial end 29 of the sealing plug 10. The second axial end 29 of the sealing plug 10 in the present case corresponds to the second axial end 16 of the sealing jacket 12.
    Taking a synopsis of all the figures of the drawing, the invention relates in summary to a sealing plug 10 for closing an anchor hole 20. The sealing plug 10 has a counter to the insertion direction in the anchor hole 20 increasing outer circumference. The sealing plug 10 in this case has a first axial end 24 with which the sealing plug 10 can be inserted into the anchor hole 20 in the front. The first axial end 24 of the sealing plug 10 may be formed more conically than the rest of the lateral surface 18 of the sealing plug 10. Preferably, the sealing plug 10 has a cap-shaped sealing jacket 12, in which - the first axial end 24 of the sealing plug 10 opposite (or opposite) accessible - a wrapping core 14 is arranged. The sealing jacket 12 is preferably made of an elastomeric polymer foam. The impact core 14 is preferably designed in the form of a steel bolt.
