Opfindelsen angår en kombination af koblingsdel og anker til opstilling og transport af plader eller pladeformede dele af beton/ hvorhos ankeret består af en langstrakt, pladeformet del, som i sin ene ende er forsynet med forankringsorganer, der som ben radeker uden for an-5 kerets plan, og som i sin anden ende er forsynet med en ankerbro og en koblingsåbning til indgreb for en låserigle på en koblingsdel, som kan være forbundet med et hejseværk.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a combination of coupling part and anchor for erecting and transporting slabs or slab-shaped parts of concrete / wherein the anchor consists of an elongated slab-shaped part, which at one end is provided with anchoring members which extend like legs outside the anchor. plane, which at its other end is provided with an anchor bridge and a coupling opening for engaging a locking bolt on a coupling part which may be connected to a hoist.

Ankerbroen på et kendt trade- og løfteanker af denne art er i overensstemmelse med det tilhørende, tilsvarende udformede koblingsorgan 10 udformet tagformet, for at angrebspunkterne på ankeret og koblingsorganet skal tilnærmes optimalt til hinanden. Præfabrikerede betonelementer, som er forsynet med sådanne indstøbte ankre som angrebspunkter for koblingsorganet på læsse-, transport- eller byggekranen, støbes som regel på hydraulisk styrede vippeborde og stilles inden læsningen på 15 højkant. Ved optagelse af lasten påvirkes ankeret ifølge sin bestemmelse hovedsageligt trækpåvirket i en retning, som er koaksial med dets længdeakse. Specielle arbejds- og driftsfordringer gør det imidlertid ofte nødvendigt, at betonelementer, navnlig betonplader, ved den første ops killing efter fremstillingen må stilles op under læsningen eller 20 losningen eller inden indføjelsen i bygningskonstruktionen. Dette er fx. ofte tilfældet, når betonelementer støbes på stedet, dvs. på byggepladsen. Et anker af den omhandlede art egner sig imidlertid i mange tilfælde ikke som opstillingsankre. Ved for ringe betonoverdækning, dvs. ved forholdsvis tynde betonplader, fører nemlig en trækbelastning, 25 som er rettet fx. vinkelret på ankerets længdeakse, til afskalning af betonen, fordi koblingsorganet ved opstillingen af det præfabrikerede betonelement kommer til at ligge an rød siden af indervæggen i betonelementets udsparing og punktvis overbelaster dette (SE-patentskrift 7305314-2 - DK-patentansøgning 1373/73).The anchor bridge of a known trade and lifting anchor of this kind is in accordance with the corresponding, correspondingly designed coupling means 10 designed roof-shaped, in order that the points of attack of the anchor and coupling means are optimally approximated. Prefabricated concrete elements, which are provided with such embedded anchors as points of attack of the coupling member on the loading, transport or construction crane, are usually cast on hydraulically controlled rocking tables and are positioned prior to loading on a high angle. In picking up the load, the anchor according to its determination is mainly affected by tensile action in a direction coaxial with its longitudinal axis. However, special work and operational requirements often require that concrete elements, especially concrete slabs, must be erected during the first cutting after manufacture during the loading or unloading process or prior to insertion into the building structure. This is e.g. often the case when concrete elements are cast on site, ie. at the construction site. In many cases, however, an anchor of the type in question is not suitable as anchorage. If there is too little concrete overlay, ie. for relatively thin concrete slabs, namely, a tensile load, which is directed e.g. perpendicular to the longitudinal axis of the anchor, for peeling the concrete, because the coupling means, in the erection of the prefabricated concrete element, will lie on the red side of the inner wall of the recess of the concrete element and overload this (point patent SE 7305314-2 - DK patent application 1373/73).

30 Samme ulempe viser sig ved et lignende opstillings- og transpor tanker, ved hvilket det i betonelementets udsparing liggende koblingsorgan på ankeret er udformet som et kuglehoved. Også her består der ved brug af ankeret til rejsning af betonelementet en risiko for en afskalning af betonen. Til sikker undgåelse af sådanne afskalninger anvendes 35 specielle opstillingskoblingsorganer. Disse har en koblingsplade, som - 2 -30 The same disadvantage is shown by a similar set-up and transport tanks, in which the coupling means lying on the anchor in the recess of the concrete element is designed as a ball head. Here too, when using the anchor to raise the concrete element, there is a risk of peeling the concrete. 35 special set-up coupling means are used to safely avoid such peeling. These have a clutch plate which - 2 -

dækker betonfærdigdelens udsparing og under anlæg mod den plane, mod koblingen vendende overflade af betonfærdigdelen griber ud over udsparingen på alle sider. De ved opstillingen optrædende kræfter afbøjes af koblingspladen ind i betonelementet.covers the recess of the concrete part and during abutment against the planar surface facing the clutch of the concrete part engages the recess on all sides. The forces occurring during the set-up are deflected by the coupling plate into the concrete element.

5 Det er endvidere kendt som tilslutningsorgan for et opstillings- og transportanker at anvende et indvendigt gevind i ankeret. Også ved et sådant anker kan der imidlerltid ved en trækpåvirkning vinkelret på ankerets længdeakse optræde afskalning af betonen. Til undgåelse af dette anvendes et særligt, som afbøjningsplade virkende eller udformet 10 koblingsstykke. Dette ligger ligeledes på alle sider an mod den plane flade af betonelementet på koblingssiden og afbøjer de ved opstillingen af betonelementet optrædende kræfter ind i elementet.Furthermore, it is known as the connecting means for an erection and transport anchor to use an internal thread in the anchor. However, even with such an anchor, however, by a tensile action perpendicular to the longitudinal axis of the anchor, peeling of the concrete may occur. To avoid this, a special or deflection plate acting as a deflection plate is used. This also lies on all sides against the plane surface of the concrete element on the coupling side and deflects the forces present in the arrangement of the concrete element into the element.

Det er også kendt at sammensvejse sådanne afbøjningsplader, som er U-forraet bukket, med ankeret. En sådan udformning har den ulempe, at 15 koblingspladen er tabt efter at være brugt én gang, dvs. den kan ikke genanvendes. Ved kendte rørformede transportankre (ankerbøsninger) griber et boltformet koblingsorgan på det tilhørende koblingsorgan på læsse- eller transportkranen ind i ankerbøsningen og strækker sig ind i et frit rum-i- betonelementet, hvor det ved hjælp af spredningsorganer gri-20 ber bag om ankerbøsningen. Sådanne transport- og opstillingsankre har den ulempe, at det nedenunder ankerbøsningen liggende fri rum, i hvilket koblingen finder sted, er udsat både for tilsmudsning og for indtrængen af vand, hvilket væsentlig forringer koblingens sikkerhed og kan føre til frostskader. Desuden er en visuel kontrol af koblingen ik-25 ke mulig. Navnlig er koblings sikkerheden ikke pålidelig, hvis fremmedlegemer, fx. små sten og lignende, kommer gennem ahkerbøsningen, ind i det fri rum.It is also known to weld such deflection plates which are U-shaped bent, with the anchor. Such a design has the disadvantage that the coupling plate is lost after being used once, ie. it cannot be recycled. In known tubular conveyor anchors (anchor bushes), a bolt-shaped coupling member of the associated coupling member of the loading or transport crane engages the anchor bush and extends into a free space-concrete element, whereby the anchor bush is gripped by means of spreading means. Such transport and mounting anchors have the disadvantage that the free space beneath the anchor bush, in which the coupling takes place, is subject to both dirt and water ingress, which significantly impairs the coupling's safety and can lead to frost damage. Furthermore, visual inspection of the coupling is not possible. In particular, the coupling security is not reliable if foreign objects, e.g. small stones and the like, coming through the aker bush, into the free space.

På grundlag af denne kendte teknik er opfindelsen baseret på den opgave at videreudforme et opstillings- og transportanker af den ind-30 ledningsvis nævnte art således, at det uden indskrænkning af den visuelle kontrol af de overfor smuds ufølsomme koblingsorganer ved koblingsoperationen er egnet til alle anvendelsesområder, navnlig også til opstilling af betonelementer og andre lastgenstande, som er særlig udsat for afskalning af beton eller andre beskadigelser, uden at materia-35 le- og fremstillingsomkostningerne forøges væsentligt, og uden at der - 3 -On the basis of this known technique, the invention is based on the object of further designing a positioning and transporting anchor of the type mentioned in the introduction so that, without limiting the visual control of the insensitive coupling means for the dirt, it is suitable for all applications. , in particular for the erection of concrete elements and other cargo objects which are particularly prone to the peeling of concrete or other damage, without substantially increasing material and manufacturing costs and without - 3 -

behøves særlige koblingslegemer eller koblingsmellemstykker til omledning af kraften.special coupling bodies or coupling spacers are needed to divert power.

Denne opgave løses ifølge opfindelsen ved, at den i patentkrav 1's indledning angivne kombination af en koblingsdel og et anker er udfor-5 met som angivet i krav 1's kendetegnende del.This task is solved according to the invention in that the combination of a coupling part and an anchor stated in the preamble of claim 1 is embodied as defined in the characterizing part of claim 1.

Denne udformning har den yderligere fordel, at de for korrosion udsatte flader af ankeret er minimale, navnlig hvis betonelementets til optagelse af ankrets tilslutningsende tjenende udsparing udstøbes (udfyldes) efter betonelementets indføjelse i bygningsværket.This design has the additional advantage that the corrosion-exposed surfaces of the anchor are minimal, especially if the recess serving to receive the anchor connecting end of the anchor is cast (filled) after the concrete element has been inserted into the structure.

10 Et sådant anker egner sig også til lastobjekter af formstof eller metal, hvis mod koblingen vendende overflade på lignende måde er ømtålelig overfor deformationer eller andre beskadigelser.Such an anchor is also suitable for cargo objects of plastic or metal whose surface facing the coupling is similarly susceptible to deformations or other damage.

Yderligere udførelsesformer ifølge opfindelsen fremgår af de uselvstændige krav.Further embodiments of the invention are apparent from the dependent claims.

5 Træk- og løfteankeret er et formstykke af fladjern med tykkelsen c og med rektangulært tværsnit. Dets basis er opspaltet langs aksen a-a. Spredningsbenene 12c er bukket ud fra ankerplanet b-b. To på tværs af ankerplanet b-b forløbende udsparinger 23 er bestemt til optagelse af armerings-jern 24. Yderligere udsparinger dannes af to overfor hinanden 10 liggende, til sikring af stillingen af et bukket armeringsjern 24a tjenende indkærvninger 25 ved ankerets Isengdekanter 21. Disse indkærvnin-ger 25 ligger mellem udsparingerne 23 og en ved ankerets tilslutnings-ende anbragt koblingsåbning 20. armerings stængerne 23, 24a og spredningsbenene 12c giver det i den færdige betonbyggedel indstøbte anker 15 en forankring, som kan holde til selv ekstremt høje trækbelastninger, som er rettet på tværs af ankerets længdeakse a-a. Ankeret 12's tilslutningsende 12a rager ikke (fig. 1 - 10) eller kun uvæsentligt (fig.5 The tensile and lifting anchor is a flat piece of iron thickness c and of rectangular cross section. Its base is split along axis a-a. The spreading legs 12c are bent from the anchor plane b-b. Two recesses 23 extending across the anchor plane bb are intended to receive reinforcing iron 24. Further recesses are formed by two opposite 10 lying to secure the position of a bent reinforcing iron 24a serving 25 at the anchor edges of the anchor 21. These notches 25 lies between the recesses 23 and a coupling opening 20 at the end of the armature 20. The reinforcing bars 23, 24a and the spreading legs 12c provide the anchor 15 embedded in the finished concrete structure part which can withstand even extremely high tensile loads which are directed transversely. of the longitudinal axis of the anchor aa. The anchor end 12a of the anchor 12 does not protrude (Figs. 1 - 10) or only insignificantly (Figs.

Den hovedsagelig af ankerbroen 12d dannede tilslutningsende 12a befinder sig nemlig i en kallot- eller slidseformet udsparing 18 i betonelementet 10. Derved lægges angrebspunktet for koblingsorganet ind i betonelementet. Desuden reduceres de for korrosion udsatte., dvs. af betonen ikke omsluttede overflader af ankeret i væ-25 sentlig grad. De bortfalder i en vis udstrækning, hvis udsparingen 18 efter indføjning af betonelementet i bygningskontruktionen udstøbes med beton. Tilslutningsenden 12a strækker sig ved koblingsoperationen så langt ind i en slidse 27 (fig. 10 og 11) i koblings organet 16, at koblingsåbningen befinder sig midt ud for styrekanalen for låseriglen 13 30 i koblingsorganet 16. Ved tilkoblingen griber låseriglen 13 gennem den visuelt kontrollerbare koblingsåbning 20.11 - 13) in addition to the plane, substantially perpendicular to the longitudinal axis of the elongated anchor, extending towards the coupling surface 11 20 of the concrete elements 10. The connecting end 12a formed mainly by the anchor bridge 12d is located in a callot or slit-shaped recess 18 in the concrete element. 10. This places the point of attack of the coupling member into the concrete element. In addition, they are reduced to corrosion, ie. of the concrete, not substantially enveloped surfaces of the anchor. They lapse to a certain extent if the recess 18, after inserting the concrete element into the building structure, is cast with concrete. The connection end 12a extends, in the coupling operation, so far into a slot 27 (Figs. 10 and 11) in the coupling means 16 that the coupling opening is in the middle of the control channel for the locking bolt 13 30 in the coupling means 16. The coupling lock 13 engages the visually controllable connection. coupling opening 20.

Fremspringene 12e har hovedsagelig rektangulært tværsnit, hvorhos en sidelængde af rektanglet tilnærmelsesvis svarer til ankerets tykkelse.The protrusions 12e are generally rectangular in cross section, with a side length of the rectangle approximately equal to the thickness of the anchor.

Begge udliggere er forsynet raed en på ankerets akse a-a vinkelret anlægsflade 14 for det 5 tilhørende koblingsorgan 16. Udliggerne 12e rager ud over ankerbroen 12d i tilslutnings retningen A og griber med deres anlægsflader 14 omkring det skiveformede koblingsorgan 16. Den tagformede bro 12d er ved ankerets akse a-a forsynet med en affladning 22.- 5 - towards the spreading legs 12c, i.e. towards the anchor end 12b. The anchor bridge 12d runs on both sides in the connection direction A into outriggers 12e, which extend beyond the base of the anchor bridge 15. Both outriggers are provided with a abutment surface 14 on the axis of the anchor perpendicular to the associated coupling member 16. The outriggers 12e extend beyond the anchor bridge 12d. connecting direction A and engaging with their abutment surfaces 14 around the disc-shaped coupling means 16. The roof-shaped bridge 12d is provided at the anchor axis aa with a discharge 22.

Den i fig. 7 viste asymmetriske variation har forneden en anlægs-10 flade 14b, som er trukket tilbage fra den væg, som begrænser udsparingen 18, og for oven findes en anlægsflade 14a, som ligger tilnærmelsesvis i plan med denne indervæg. Hvis det af bygge- eller læssekranen udøvede træk i et forbindelsesorgan 17, som griber ind i en central åbning 19 i det ringformede koblingsorgan 16, forløber i retningen B (op-15 stilling af betonfærdigdelen), ligger koblingsorganet 16 an mod den i opstillingsretningen liggende udligger 12e's anlægsflade 14a eller 14b.The FIG. 7, asymmetrical variation shown below has a abutment surface 14b which is withdrawn from the wall limiting recess 18, and above it abuts abutment surface 14a which is approximately in plane with this inner wall. If the feature exerted by the building or loading crane in a connecting member 17 engaging a central opening 19 of the annular coupling member 16 extends in the direction B (positioning of the finished concrete part), the coupling member 16 abuts the positioning in the alignment direction. the abutment surface 14a or 14b of the 12e.

I den i fig. 8-10 viste variation løber ankerbroen 12d ligeledes på begge sider ud i udliggere 12e, som rager ud over ankerbroen 12d's basis 15. Begge udliggere er forsynet med en vinkelret på ankerets akse 20 a-a forløbende anlægsflade 14c, mod hvilken koblingsorganet 16 ligger an under opstillingsoperationen. Anlægsfladerne 14c går over i hinanden gennem ankerbroen 12d's cirkelformet krummede basis 15. De to med ankeret 12's længdekanter 21 flugtende udliggere 12e griber under koblingsoperationen ind i en notagtig fordybning 26 i koblingsorganet 16. Ind-25 gangene til disse fordybninger 26 udmunder i optagelsesslidser 27 i koblingsorganet. Fordybningerne ligger mellem optagelsesslidsen 27 for ankerets tilslutningsende 12a og den centrale åbning 19 i koblingsorga net. Ved påvirkning af ankeret 12 som opstillingsanker (tiækretning B) ligger en anlægsflade 14c an mod en indenfor koblingsorganet 16's tvær-30 snit liggende væg 26a i fordybningen 26. Afstanden d-d mellem de plane, hovedsagelig parallelt med ankerets akse a-a forløbende anlægsflader 14c er mindre end tykkelsen y af det skiveformede koblingsorgan. Den plane væg 26a går gennem skråflader 26b over i koblingsorganets hovedsagelig plane væg 16a. De to fordybninger 26 ender foran koblingsorga-35 nets centrale åbning 19.In the embodiment shown in FIG. 8-10, the anchor bridge 12d also extends on both sides into outriggers 12e which extend beyond the base 15 of the anchor bridge 12d. Both outriggers are provided with a perpendicular abutment surface 14c of the anchor 20 against which the coupling means 16 abuts during the erection operation. . The abutment surfaces 14c intersect through the circularly curved base 15 of the anchor bridge 12d. the coupling member. The recesses lie between the uptake slot 27 of the anchor connection end 12a and the central opening 19 of the coupling means. On impact of the anchor 12 as the anchor (extension B), a abutment surface 14c abuts against a wall 26a within the cross-section of the coupling member 16a in the recess 26. The distance dd between the planes, mainly parallel to the axis of the anchor extending to abutment surfaces 14c is less than the thickness γ of the disc-shaped coupling means. The flat wall 26a passes through inclined surfaces 26b into the substantially flat wall 16a of the coupling means. The two recesses 26 end in front of the central opening 19 of the coupling member 35.

Ved den i fig. 11 - 13 viste variation griber en i ankerets akse a-a liggende udligger 12f med to overfor hinanden liggende anlægsflader 14d ind_i. en. central fordybning 28 i koblingsorganet. Fordybningen er af en på begge sider åben kanal, som strækker sig fra slidsen 27 til 5 koblingsorganet 16's centrale åbning 19, og som har hovedsagelig kvadratisk tværsnit. Kanalens lysning er lidt større end tværsnittet af den indgribende-udligger 12f. En af anlægsfladerne 14d ligger under opstillingsoperationen an mod en parallelt med ankeret 12's længdekant 21 forløbende væg i kanalen.In the embodiment shown in FIG. 11-13, a projection 12f lying in the anchor axis a-a with two abutting abutment faces 14d engages. one. central recess 28 in the coupling means. The recess is of a channel open on both sides extending from the central opening 19 of the slit 27 to 5 of the coupling means 16 and having a generally square cross-section. The channel illumination is slightly larger than the cross-section of the engaging recess 12f. One of the abutment surfaces 14d lies during the erection operation against a wall extending parallel to the longitudinal edge 21 of the anchor 12 in the channel.

10 I de to variationer ifølge fig. 8- 10 og 11 -13 forløber anke rets længdekanter 21 indbyrdes parallelt. Disse to variationer egner sig på grund af deres særlige udformning og navnlig på grund af indgrebet af deres udliggere i fordybninger i koblingsorganet navnlig til meget tyndvæggede betonplader eller tyndvæggede betonelementer, eftersom 15 ankerets bredde ved ankerbroen 12d, som danner ankeret 12*s tilslutningsende, kun overstiger tykkelsen y af koblingsorganet uvæsentligt.10 In the two variations according to FIG. 8- 10 and 11 -13 extend the length of the appellate 21 parallel to each other in parallel. These two variations are suitable because of their special design and, in particular, because of the engagement of their outriggers in recesses in the coupling means, in particular for very thin-walled concrete slabs or thin-walled concrete elements, since the width of the anchor at the anchor bridge 12d forming the anchorage 12 * ends only substantially exceeds the thickness γ of the coupling means.

I alle udførelseseksenqpler undgås med sikkerhed en punktvis trykpåvirkning af betonelementet i det kritiske område for det i betonelementets udsparing 18 indgribende koblingsorgan 16. Dette opnås ved en 20 særdeles enkel foranstaltning, som næppe forårsager yderligere omkostninger. Endvidere er ankeret ved påvirkning i trækretningen B sikret mod sprækkedannelse og udrivning ved hjælp af armeringsstængerne 24 og 24a og ved spredningsbenene 12c. Samtidig er det bukkede armerings jern 24a understøttet ved C (fig. 1). Armerings jernet 24 er understøttet i 25 samme retning. Spredningsbenene 12c er ved D (fig. 1) understøttet i modsat retning.In all embodiments, a point-to-point pressure effect of the concrete element in the critical area of the coupling member 16 engaging in the concrete element recess 16 is certainly avoided. This is achieved by a very simple measure, which hardly causes additional costs. In addition, the anchor is actuated in the pull direction B against cracking and tearing by means of the reinforcing bars 24 and 24a and by the spreading legs 12c. At the same time, the bent reinforcement iron 24a is supported at C (Fig. 1). The reinforcing iron 24 is supported in the same direction. The spreading legs 12c are supported by D (Fig. 1) in the opposite direction.
