Definitions
- the invention relates to a storage box and a closure element for the protective and supporting receiving the head ends of connection terminals as used in concrete construction.
- Such a storage box for receiving the connection connections in concrete construction usually has a box-shaped or rail-shaped open on both sides, completed a hollow body forming basic structure.
- the connecting terminal elements which are intended to be introduced into the here in question storage boxes to be available when needed for making the connection of a precast concrete to other concrete structural elements can be reinforcing bars, loops of reinforcing wires or elastic steel cable loops. Because of their ease of use on the construction site, especially elastic steel wire rope loops are widely used as connection terminal elements. In this case, a loop formed from the steel cable is closed as a connection head in the storage box, while the opposite angled "foot" of the connection connection element led out of the storage case protrudes into the concrete casting mold and poured in during casting of the precast concrete element and thereby anchored in the concrete.
- connection molding or, alternatively, relaxed, that is, extending in a plane inserted into the implementation in the box bottom and then bent exciting and is fixed bent at right angles under holding elements, which are formed either on a separate intermediate molding or on the Verwahrkastenprofil itself or otherwise provided.
- the British patent application GB 2 193 513 A also shows such an anchor rail for receiving a variety of forms of fasteners.
- German patent application DE 195 25 338 A1 discloses a reinforcing element for a prepared to be prepared reinforcement connection between two meeting wall parts in reinforced concrete, consisting of a box-shaped, closed on all sides, the reinforcing iron receiving structure made of sheet metal, housed in the interior of a part of the reinforcing bars and their anchoring brackets are the building by cross-protruding outwardly projecting ,
- the invention is based on the technical problem, in particular the front side closure of the custody boxes be designed so that with a simple and quick assembly handling a dense and against the pressure of liquid concrete sludge also mechanically stable closure of the storage box can be obtained. It is a further aspect of the invention, including the mold elements and moldings for clamping and inserting the connection terminal elements into the storage box s to further develop that with the closing of the side wall surfaces of the storage boxes on the one hand and with the to be developed for insertion of the connecting terminal elements moldings, on the other hand, a synergism can be achieved, which improved to one in its technical characteristics equipped and closed storage box leads, which is also cheaper to produce than by the known method.
- the invention solves this problem by the formation of the side wall closure element as a sealing plug, and specifically as axially in the storage box in depressible sealing plug, wherein the closure plug carries on a insertable into the storage box shaft or web pre-assembled a connection connection element.
- the sealing plugs are preferably tapered axially inwardly with radially inwardly slightly inclined pyramid surfaces, so that the plug has at least in the application area a total truncated pyramidal outer configuration. As a result, the plug can be wedged tightly and sealingly in the deposit box opening.
- plugs may be provided with resilient pawls engageable with configuratively cooperative recesses formed on the inside of the frontally open storage box.
- the sidewall sealing plug of the storage box is in particular configured so that it carries the connection connection element, in particular preferably already in the intended angled form, preassembled on an insertable into the storage box shaft or web.
- a cutout is provided in the bottom of the storage box after axially outward opening which forms a Passage of the concrete-side foot end of the connection connection element when pushing the Stopfems allows.
- axially extending grooves are formed in connection therewith on the bottom area of the shank portion of the sealing plug, which receive the mutually axially opposite inner edges of the bottom section of the storage box to form a tongue and groove plain bearing connection. The passage opening in the storage box is thereby sealed concrete slurry.
- FIG. 1 shows a first embodiment of a sealing plug with the features of the invention, which serves to close the open end of a storage box with trapezoidal cross-section.
- the closure plug 1 has two major configurational structures, namely a closure plug plate 2 for sealing the open end side of the storage box, and a shaft 3, which is integrally connected to the closure plug plate 2.
- the side surfaces 4 of the closure plate 2 are towards the shaft 3, so, based on the longitudinal extent of the storage box, axially inwardly to conical, truncated pyramidal or wedge-shaped tapered and serve as sealing surfaces of the sealing plug 1 relative to the front edge region of the inner wall surface of the Storage box (10) ( Fig. 5 ).
- the transversely short sealing surfaces 4.1 and the long sealing surfaces 4.2 with the two opposing surfaces 5.1 and 5.2 of the shaft 3 are each in a plane, so that the shaft 3 is configured slightly wedge-shaped. They serve in this configuration, the facilitated and guided insertion of the sealing plug 1 in the open end wall of the storage box.
- the inclination of the sealing surfaces 4 of the closure plate 2 is dimensioned so that when properly mounted the plug in the axial depression of the sealing plug 1 in the storage box 10 after forming a snug fit with frictional engagement, which firmly and sealingly fixed the plug in the storage box, the axially outer end face 6 of the closure plate 2 with the front edge 15 of the storage box 10 is aligned.
- the shaft 3 is used in the manner described above, the easier insertion of the sealing plug.
- the shaft 3 of the closure plate 2 of the sealing plug 1 is simultaneously designed for the embodiment described here, that it serves the angled or angled fixing a connection connection element.
- the shaft 3 has a continuously open vertical opening 7, which serves as a passage for the foot end of a not shown here and in the deposit box connection connection element, while being housed in the storage box head portion of the connection connection element under undercuts 8.1 and 8.2 coaxial with the extension of Verwahrkastens or coplanar is held to the bottom and lid.
- a cutout 11 is provided in the trolley bottom 9, which also allows the axial sealing impressions of the Veschlußstopfens 1 in the open end of the storage box 10, when the closure plug 1 also serves as a mounting bracket for the connection terminal element.
- closure plug 1 elastically latching pawls 27 ( FIG. 1 ), which in the insertion of the plug in the storage box 10 in associated recesses 28 ( Fig. 6 ) indissably engage in the inner wall of the storage box 10.
- FIGS FIG. 2 A second embodiment of a sealing plug 1 with the features of the invention is shown in FIGS FIG. 2 shown.
- the closure plug 1 consisting of the closure plate 2 and the shaft part 3 serves primarily for sealing the open front side surface of the storage box 10 in the manner described above.
- the rectangular shaft 3 is configured so as to enable convenient pre-assembly of a flexible steel cable loop as connection connection element ,
- the undercuts 8.3 and 8.4 on the shaft 3 are not formed up to the axially inner wall 12 of the plug closure plate 2 and also not aligned with the sealing surface 4.1 of the closure plate 2.
- the axially shortened configuration of the undercuts 8.3, 8.4 allows initially relaxed insertion of a flat elastic wire rope loops in the opening 7 and a subsequent right-angle elastic bending of the loop head to axially inside and pressing the cable loop wires under the undercuts against the elastic bias.
- the deepening of the undercuts 8.3, 8.4 and thus also the surfaces 5.1 of the shaft 3 ensure that a fixed connection to the shaft connection element, in particular an elastic wire rope loop, when closing the storage box with the equipped plug a grinding of the closure element on the lid or the imposition of a bias can be excluded on the lid radially outward.
- the shaft 3 in the off FIG. 2 apparent manner with two axially extending guide grooves 13 which receive the parallel opposite axial portions 14 of the bottom 9 of the storage box 10 in the region of the cutout 11 as a leader leader, sealing and stabilizing.
- the bottom surface 5.2 of the shaft 3 of the sealing plug 1 is supported in its axially inner region on the surface of the bottom 9 lying inside in the storage box.
- the sealing surfaces 4 of Stopper plate 2 dense in the same manner as above in connection with the FIG. 1 explained on the inner wall of the storage box 10 in the region of the front side edge 15th
- a third embodiment of the invention is in the FIG. 3 shown, also in perspective view.
- the stopper 1 shown there differs from the two previously described stopper according to the embodiments 1 and 2, characterized in that the closure plate 2 axially outside with a stop plate 16, and integrally connected thereto, formed, whose axially inner wall surface, the stopper plate 2 collar-shaped encloses.
- This circumferential collar surface 17 of the stop plate 16 is coplanar with the closure plate 2 and aligned with the front side edges 15 of the storage box 10. It thus allows a reproducible in series production insertion of the sealing plug in the storage box 10 and also serves as an additional sealing surface in cooperation with the front side edges 15 of the storage box 10. It should be noted here that the representation of FIG.
- the width of the collar surface 17 is sized to be at least substantially equal to the width of the front side edges 15 of the storage box so that the outer peripheral surfaces 18 of the stop plate 16 are aligned with the outer surfaces 19 of the storage box 10.
- the closure plug 1 according to the in FIG. 3 shown axially inside an insertion bevel 20, which also includes a mechanical insertion of the sealing plug into the storage box 10 by accordingly controlled production machines allows.
- FIG. 4 a fourth embodiment of the invention is shown, which shows a further embodiment of the in FIG. 2 shown sealing plug shows.
- the in FIG. 4 shown sealing plug is used especially for the pre-assembled receiving elastic cable loops as a connection terminal element.
- the embodiment shown in FIG. 4 embodiment shown above all by an extension of the closure plate shank 3 in the axial direction and an arrangement of the undercuts 8.3, 8.4 at a greater axial distance from the bending curvature of the elastic cable loop.
- larger radii of curvature and improved resilience of the elastic steel cable loop are made possible.
- Such an increase in the bending radius can be promoted by bending the elastic steel cable loop via a bar 22 with a rounded bending edge 23, which is provided as a cross bar between the feed-through opening 7 and the hold-downs or undercuts 8.3, 8.4.
- the sealing plugs with the features of the invention are used to close the open end faces of storage boxes with box-shaped or rail-shaped hollow body basic structure as used for the protection of connection connection elements in precast concrete construction. Even if the recognizable advantages of the sealing plug with the features of the invention also in connection with initially open channel-shaped boxes, which only after the axial pressing of the sealing plug with a lid can be used, are used, the advantages of the sealing plug come with the features of the invention particularly fully to fruition when it comes to already closed as a finished and closed, only the frontally open hollow box profile trained deposit boxes. Such an integrally formed, closed on the end faces hollow box profile as Verwahrkasten body is in the FIG. 5 shown.
- Verwahrkastenprofil is trapezoidal in cross section, so that even with an open lid closing the open end faces by adhesive tape or screwing in weirs is no longer possible.
- Such storage boxes for concrete construction however, despite their trapezoidal cross-section with the sealing plug with the features of the invention easily and even by machines and, if necessary, even with pre-assembled connection connection elements can be equipped and reliable and concrete sludge sealable.
- FIG. 5 Storage box shown is the illustrated open end face for receiving sealing plug as determined above in connection with the FIGS. 1 to 4 have been described.
- a cutout 11 is provided, can be introduced through the axially inward of the foot sections of the connection connection elements.
- recesses 25 may be formed in the axially inner end-side stop edge 24, which are configured for a sealing reception of the strands of a connection connection element that have been made. You can, for example, with appropriately guided and configured guide grooves 21 interact, which in the Figures 3 and 4 are shown for the closure plugs shown there and explained in connection with these figures.
- FIG. 6 an alternative form of the embodiment of the section 11 of a storage box 10 is shown in which the Recesses for the passages of the connecting terminal strands are not adjacent to each other on the axially inner stop edge 24, but are provided in the mutually parallel axial edges 14 as a mirror-symmetrical opposing recesses 26.
- FIGS. 1 to 4 as well as in the Figures 5 and 6
- Deposit box configurations and closure elements are described by way of examples with the features of the invention, starting from a constellation in which the closure element is at the same time a carrier of a particular pre-assembled connection connection element.
- the axially opposite open end of the Verwahrkastens is usually also closed with an axially compressible in the storage box stopper, with or without shank part 3 and with or without stop plate 16 means closed a Viefussopfens, only the closing function of the closure plate 2 has.
- such an open end face of the storage box has no cutout 11
- such an open end face can also with plugs, for example, in the FIGS. 1 and 3 shown type with a passage opening 7 tight and tightly closed.
- the closure stopper in addition to the sealing closure plate 2, must have a shank 3, in particular in FIG FIG. 1 have shown type in which at least no opening 7 is open.
- the invention thus discloses a storage box and a closure element for closing one or both open end sides of such a storage box with box-shaped or rail-shaped hollow body basic structure for the concrete-tight receiving connection connection elements.
- the closure elements are configured as plugs which can be pressed axially into the storage box, thereby enabling a reliable and automatable sealing and closing of non-rectangular or non-square storage box profiles.
