Description
Beskrivelse Nærværende opfindelse angår et vægelement ifølge indledningen til krav 1 og en kombination af et lastoptagelsesmiddel og et vægelement ifølge indledningen til krav 8.The present invention relates to a wall element according to the preamble of claim 1 and a combination of a load-picking means and a wall element according to the preamble of claim 8.
Med begrebet "manipulering" skal her forstås transporten, opstillingen samt alment håndteringen af eksempelvis præfabrikerede betonelementer, især af flerlagsvægge, ved hjælp af transportankersystemer.The term "manipulation" here means the transport, installation and general handling of, for example, prefabricated concrete elements, especially of multilayer walls, by means of transport anchor systems.
Et konstruktionselement i opfindelsens betydning er følgelig helt alment et flerlags plant konstruktionselement, som omfatter to i indbyrdes afstand anbragte lag af konstruktionsmaterialer - for det meste beton Disse to lag er sædvanligvis indbyrdes forbundet ved hjælp af forbindelsesorganer, som eksempelvis kan være udformede i form af afstandsholdere, som kan have forskellige konstruktionsformer. Særlige foranstaltninger skal tilvejebringes ved manipulering for indgribningen af lastoptagelsesmidlerne med transportankrene underforskellige hældningsvinkler.Accordingly, a structural element within the meaning of the invention is generally a multilayered flat structural element comprising two spaced layers of structural materials - mostly concrete. These two layers are usually interconnected by means of connecting members, which may, for example, be formed in the form of spacers. , which can have different types of construction. Special measures must be provided in manipulating the loading of the load-taking means with the transport anchors at different angles of inclination.
Adskillige dokumenter beskriver sådanne indretninger. I AT PS 349715 vises og beskrives et opstillings- og transportanker til indlejring i præfabrikerede betonelementer. Et anker i form af et plant stålformstykke med rektangulært tværsnit er indstøbt således i det præfabrikerede betonelement, at indgrebspunktet for koblingshovedet på lastoptageren er indskudt i det præfabrikerede betonelement. Derved skal en punktformet trykbelastning af det præfabrikerede betonelement undgås i det kritiske område. I DE 103 51 487 A1 er en indretning og en fremgangsmåde til transport af et vægkonstruktionselement vist og beskrevet. Ved vægkonstruktionselementet drejer det sig om en såkaldt dobbeltvæg. Et sådant vægkonstruktionselement kan eksempelvis fremstilles i en fabrik, og transporteres til en byggeplads. Der kan adskillige elementer opstilles ved siden af hinanden og indbyrdes forbindes ved, at der i mellemrummet indføres beton blandet på stedet. Helt alment omfatter et vægkonstruktionselement to betonlag. Det er imidlertid også tænkeligt, at et vægkonstruktionselement omfatter et betonlag og et i afstand derfra beliggende yderligere lag, som ikke er fremstillet af beton, men eksempelvis omfatter et isolationslag, idet de to væglag er indbyrdes forbundet ved hjælp af afstandsholdere. Den der foreslåede indretning til transport af vægkonstruktionselementet består af adskillige uafhængige konstruktionsdele, hvoraf to er forankrede i respektive endesider af de to væglag. Den der viste indretning skal ikke have nogen uønsket indflydelse på varmeisolationen af vægkonstruktionselementet.Several documents describe such devices. AT PS 349715 shows and describes an installation and transport anchor for embedding in prefabricated concrete elements. An anchor in the form of a flat steel die with rectangular cross-section is embedded in the prefabricated concrete element so that the point of engagement of the coupling head on the load handler is inserted into the prefabricated concrete element. In this way, a point-shaped compressive load of the prefabricated concrete element must be avoided in the critical area. In DE 103 51 487 A1, a device and method for transporting a wall construction element are shown and described. At the wall construction element it is a so-called double wall. For example, such a wall construction element can be manufactured in a factory and transported to a construction site. Several elements can be arranged side by side and interconnected by introducing concrete mixed in the space. In general, a wall construction element comprises two concrete layers. However, it is also conceivable that a wall construction element comprises a concrete layer and a further layer located therefrom which is not made of concrete, but for example comprises an insulation layer, the two wall layers being interconnected by means of spacers. The device proposed for transporting the wall construction element consists of several independent structural parts, two of which are anchored to respective end sides of the two wall layers. The device shown must have no undesirable influence on the thermal insulation of the wall construction element.
En afstandsholder med bæreankerfunktion er vist og beskrevet i DE 200 08 530 U1. Den der beskrevne afstandsholder for et betonhulrumselement er udformet som en i et stykke dobbeltkonisk udformet afstandsstav, hvis ene ende omfatter en fastgørelsestallerken og hvis anden ende omfatter støtteknaster. Afstandsstaven tilspidses mod midten og tilvejebringer derved en udsparing for en krankrog. Den der beskrevne afstandsholder er udformet som multifunktionselement, som på den ene side fungerer som afstandsholder, på den anden side som optagelseselement for en krankrog og som desuden tilvejebringer en forankring for præfabrikerede elementer.A carrier with carrier anchor function is shown and described in DE 200 08 530 U1. The spacer described for a concrete cavity element is configured as a spacer double-conical spacer, one end of which includes a fastening plate and the other end of which includes support studs. The spacer is tipped toward the center thereby providing a recess for a crane hook. The spacer described therein is designed as a multifunctional element which, on the one hand, acts as a spacer, on the other hand as a mounting element for a crane hook and which further provides an anchorage for prefabricated elements.
Fra FR 2 948 139 A1 kendes et vægelement for fremstillingen af bygningsanlæg, ved hvilket et tov er indstøbt i elementlagene, idet tovet er positioneret i elementlagene via holdere. Dette dokument omtaler alle de tekniske træk i indledningen til krav 1. Fra DE 199 46 320 A1 kendes et vægelement med i indbyrdes afstand placerede elementlag, hvor elementlagene er indbyrdes forbundet via stålrør, med hvilke et løfteaggregat kan indgribe.From FR 2 948 139 A1 a wall element is known for the manufacture of building systems, in which a rope is embedded in the element layers, the rope being positioned in the element layers via holders. This document describes all the technical features of the preamble of claim 1. From DE 199 46 320 A1, a wall element is known with spaced element layers, the element layers being interconnected via steel pipes with which a lifting unit can intervene.
Fra EP 0 872 609 A2 kendes en fremgangsmåde til fremstilling af flerlagsmurplader, ved hvilken den udvendige skal opmures af tegl, idet den udvendige skal henholdsvis teglrækker via afstandsrør, som er indskudt i præborede boringer, forbindes indbyrdes. Igennem afstandsrørene kan transportbolte indstikkes, hvormed transportremme kan indgribe. Nærværende opfindelse har i forhold hertil den opgave, at tilvejebringe indretninger til manipulering af flerlags plane bygningselementer, som ikke har ulemperne ved den kendte teknik. Yderligere skal den forene så mange som mulige af følgende egenskaber: Opretholdelse af varmeisoleringen af dobbeltvægge; anvendelse i forbindelse med forskellige vægtykkelser; standardisering af så mange som mulige enkelte elementer; enkel indbygning på fabrik; ingen efterbearbejdning ved indbygning; genanvendelighed; returtransportmulighed; drejelighed af vægelementerne ved manipulering og lastindgreb fra forskellige vinkler. Denne opgave løses af et vægelement ifølge krav 1 og en kombination af et lastoptagelsesmiddel og et vægelement med de i krav 8 angivne træk. Fordelagtige udførelsesformer er angivet i de afhængige krav.EP 0 872 609 A2 discloses a method for the manufacture of multilayer masonry plates in which the exterior shell is walled with bricks, the exterior shell and brick rows, respectively, via spacers inserted in pre-drilled bores are interconnected. Through the spacers, transport bolts can be inserted, which means that the conveyor belts can engage. The object of the present invention is to provide devices for manipulating multi-layer planar building elements which do not have the disadvantages of the prior art. In addition, it must combine as many of the following characteristics as possible: Maintaining the thermal insulation of double walls; use in connection with various wall thicknesses; standardizing as many individual elements as possible; simple factory installation; no post-machining; recyclability; return transport option; rotatability of the wall elements by manipulation and load engagement from different angles. This task is solved by a wall element according to claim 1 and a combination of a load-picking means and a wall element with the features of claim 8. Advantageous embodiments are set forth in the dependent claims.
De særlige fordele ved indretningen ifølge opfindelsen ligger i dennes enkle opbygning, den problemløse håndtering, den omkostningsgunstige fremstillelighed samt i genanvendeligheden for de udløselige konstruktionselementer. Eftersom de respektive sammenhørende henholdsvis samvirkende lastoptagende formdele er beliggende i indbyrdes afstand, opstår der ikke nogen uønsket varmebro. De lastoptagende formelementer skal ikke være adskilt fuldstændigt fra hinanden eller kunne adskilles. En til montageformål foreliggende forbindelse holder varmeoverføringen imellem overfor hinanden liggende formdele så ringe som mulig og kan i givet fald være bortfjemelig. I indretningen ifølge opfindelsen er formdelene udformede som cylindre og forankrede i elementlagene og stikker ud over indersiderne af elementlagene. Yderligere er et transportanker til anvendelse i en af de ovenstående indretninger fordelagtig, når transportankrene for forskellige vægtykkelser og/eller forskellige afstande imellem elementlagene er standardiserede og fri for efterbearbejdning kan indføres i elementlagene.The particular advantages of the device according to the invention lie in its simple construction, the trouble-free handling, the cost-effective manufacturing and in the reusability of the releasable structural elements. Since the respective interconnecting and cooperating load-receiving mold portions, respectively, are spaced apart, no undesirable heat bridge arises. The load-bearing mold elements must not be completely separated or separable. A connection for mounting purposes keeps the heat transfer between opposite mold parts as low as possible and can be removable if necessary. In the device according to the invention, the mold members are formed as cylinders and anchored in the element layers and protrude beyond the inside of the element layers. Further, a conveyor anchor for use in any of the above devices is advantageous when the conveyor anchors for different wall thicknesses and / or different distances between the element layers are standardized and can be introduced into the element layers free of post-machining.
Desuden er en kombination af et lastoptagelsesmiddel og et vægelement fordelagtig, idet et lastoptagelsesmiddel foreligger til manipulering af vægelementer, hvor lastoptagelsesmidlet kan forbindes med et anhugningsorgan på en kran til løftning eller transport af vægelementet, og når lastoptagelsesmidlet råder over formelementer, som korresponderer formbetinget med transportankrene i overensstemmelse med de foregående krav.In addition, a combination of a load-picking means and a wall element is advantageous in that a load-picking means is available for manipulating wall elements, where the load-picking means can be connected to a tugging member on a crane for lifting or transporting the wall-element, and when the load-picking means has mold elements corresponding to the shape condition with the transport condition. in accordance with the preceding claims.
Lastoptagelsesmidler er også en fordel, når fremstillingen og/eller løsningen af den formbetingede forbindelse imellem lastoptagelsesmidlet og transportankrene sker manuelt eller automatisk pr. fjernudløsning.Load pick-up means are also an advantage when the preparation and / or solution of the molded connection between the load pick-up means and the transport anchors is carried out manually or automatically per hour. remote release.
Desuden kan det være gunstigt, at formdelene i lastoptagelsesmidlet kan genanvendes.In addition, it may be beneficial that the mold parts of the load-picking means can be reused.
Ved hjælp af udførelseseksempler skal opfindelsen i det følgende forklares nærmere i forbindelse med tegningerne. På tegningerne viser:By way of example, the invention will now be explained in more detail in connection with the drawings. In the drawings:
Fig. 1 kraftigt skematiseret et perspektivisk billede af et vægelement på krogen af en ikke vist kran; fig. 2 et vægelement ifølge fig. 1 med delvis udskåret væglag; fig. 3 en detalje af et cylindrisk transportanker med formbetinget lastoptager; fig. 4 et montagearrangement med transportankre ifølge fig. 1 til 3 i montagetilstand; fig. 5 en yderligere udførelsesform for et transportanker i tværsnit på tværs igennem et vægelement og fig. 6 et snit langs et midterplan igennem vægelementet i fig. 5. I fig. 1 er et vægelement 1 vist på krogen 2 af en ikke vist kran. Afbildningen anskueliggør en indretning ifølge opfindelsen til manipulering af flerlags plane konstruktionselementer i form af et vægelement 1 til fremstillingen af bygningsanlæg. Hertil er i det mindste to i det væsentlige indbyrdes parallelt i afstand beliggende elementlag 3, 4 nødvendige, som hver især omfatter indvendige 5 og udvendige sider 6. Med indvendige sider 5 og udvendige sider 6 skal forstås begrænsningssiderne med stort areal, og ikke de smalle flader, som betegnes endesider 7. Elementlagene 3 og 4 er via afstandsholdere 8 indbyrdes forbundet. Elementlagene 3 og 4 har et transportanker, som er anbragt i form af formdele 9 på deres indvendige flader 5, og er forbundet med lastoptagelsesorganer 10 til manipulering med et vægelement 1, som her er vist som en dobbeltvæg. Transportankeret er udformet i form af separate henholdsvis i indbyrdes afstand beliggende formdele 9 i form af cylindriske bøsninger, som - adskilt fra hinanden men nøjagtigt flugtende og liggende på en fælles akse - er anbragt på de indvendige sider 5 i vægelementet 1. De kan imidlertid også være udformede som formdele med anden konstruktion på eller i ydersiden af en vægelement 1, men denne alternative udformning udgør ikke nogen del af den kravsatte genstand. Afgørende er, at der imellem lastoptagelsesmidlerne 10 og formdelene 9 i transportankeret kan tilvejebringes en funktionsmæssig forbindelse, som forklares nærmere ved hjælp af de øvrige figurer.FIG. 1 is a heavily schematic perspective view of a wall element on the hook of a crane not shown; FIG. 2 shows a wall element according to FIG. 1 with partly cut wall layer; FIG. 3 shows a detail of a cylindrical transport anchor with a molded load handler; FIG. 4 shows a mounting arrangement with transport anchors according to FIG. 1 to 3 in mounting mode; FIG. 5 shows a further embodiment of a cross-sectional transport anchor through a wall element; and FIG. 6 is a section along a central plane through the wall element of FIG. 5. In FIG. 1 is a wall element 1 shown on the hook 2 of a crane not shown. The depiction illustrates a device according to the invention for manipulating multi-layer planar structural elements in the form of a wall element 1 for the construction of building systems. To this end, at least two substantially mutually spaced element layers 3, 4, each of which comprises interior 5 and exterior sides 6, are necessary. Interior sides 5 and exterior sides 6 are to be understood as the large area boundary sides, and not the narrow ones. surfaces which are termed end sides 7. The element layers 3 and 4 are interconnected via spacers 8. The element layers 3 and 4 have a transport anchor arranged in the form of mold members 9 on their inner surfaces 5, and are connected to cargo picking means 10 for manipulation with a wall element 1, which is shown here as a double wall. The conveyor anchor is formed in the form of separate or spaced apart mold portions 9 in the form of cylindrical bushes which - separated from each other but exactly flush and lying on a common axis - are arranged on the inner sides 5 of the wall element 1. However, they can also be may be formed as mold members with other construction on or outside of a wall element 1, but this alternative design does not form part of the required object. It is crucial that between the load-picking means 10 and the mold parts 9 in the transport anchor a functional connection can be provided, which is explained in more detail by the other figures.
Fig. 2 viser genstanden ifølge fig. 1, men med udskåret elementlag 4. Det ses, at lastoptagelsesmidlet 10 samvirker med formdelene 9 i transportankeret således, at de som cylinderformede bøsninger udformede formdele 9 skovllignende omgribes af en halvskal 11, som udgør den frie ende af lastoptagelsesmidlet 10. Den imod det udskårne elementlag 4 vendende cylindriske formdel 9 er, på grund af det bortskårne elementlag 4, i en vis grad vist fritsvævende og befinder sig naturligvis i elementlaget 4. De to cylindriske formdele 9 er indbyrdes separate, men eksakt i en fælles akse flugtende, hver især indstøbt i de indvendige sider 5 i elementlagene 3 og 4 i vægelementet 1, således at det er tilsikret, at halvskallen 11 i lastoptageren 10 præcist omslutter de cylindriske bøsninger 9. Den cylindriske udformning af formdelene 10 og halvskallen 11 på lastoptageren 10 muliggør en rotationsbevægelse imellem transportankeret og lastoptageren 10, således at ved forskydninger af vægelementet 1 under dettes bevægelse kan der ikke opbygges nogen uønskede spændinger. I fig. 3 skal denne sammenhæng, ved hjælp af en anden synsvinkel på genstanden ifølge opfindelsen, gøres endnu tydeligere. De to elementlag 3 og 4 i vægelementet 1 er vist forstørret, idet elementlaget 4 - som i afbildningen ifølge fig. 2 - er udskåret, således at den til højre viste formdel 9 synes frit svævende, men i realiteten naturligvis er fast forankret i elementlaget 4 og fra dettes indvendige side 5 rager ind i mellemrummet 12 i vægelementet 1. Lastoptagelsesmidlet 10 griber omkring de to præcist på en akse liggende formdele 9 af transportankeret med sin ved den frie ende beliggende halvskal 11.1 praksis bliver lastoptagelsesmidlet 10 manuelt indført i mellemrummet 12 og bragt i position i forhold til formdelene 9. For at mulige positionsændringer af vægelementet 1 ikke skal føre til skader, har halvskallen 11 på lastoptagelseselementet 10 tværvægge 13, som ligger således pasnøjagtigt an mod formdelene 9, at en ved transport muligvis optrædende forskydning imellem halvskallen 11 og formdelene 9 forhindres. Imellem de indvendige sider 5 af elementlagene 3 og 4 og halvskallen 11 kan der foreligge en afstand. En utilsigtet udhaspning af lastoptageren 10 forhindres ved hjælp af en arreteringsstift 14. Til tilsigtet udløsning af lastoptageren 10 fra kontakt med formdelene 9 kan arreteringsstiften 14 bringes til en frigivelsesposition (ikke vist). Frigivelsespositionen kan tilvejebringes manuelt, fordelagtig er imidlertid en fjernstyret frigivelse, som eksempelvis udløses ved et fjernstyringsradiosignal, som elektromagnetisk bevirker en positionsændring for arreteringsstiften 14. Arreteringsstiften 14 kan erstattes af andre arreteringssystemer, som eksempelvis fjernudløses ved hjælp af snoretræk. I fig. 4 er vist et montagearrangement 15 med et transportanker, som anskueliggør montagen i begyndelsesfasen ved fremstillingen af et vægelement 1. Montagearrangementet 15 omfatter to formdele 9, som danner transportankeret og som er forbundet eksakt flugtende indbyrdes i en forudbestemt afstand ved hjælp af en manchet 16.FIG. 2 shows the object of FIG. 1, but with cut element layer 4. It will be seen that the load-picking means 10 cooperates with the mold parts 9 in the transport anchor, so that the shaped parts 9 formed as cylindrical bushes are bucket-like surrounded by a half shell 11, which forms the free end of the load-picking means 10. element layer 4 facing cylindrical mold part 9, due to the cut element layer 4, is shown to be to some extent free-floating and is naturally in the element layer 4. The two cylindrical mold parts 9 are mutually separate, but exactly in a common axis, each embedded in the inner sides 5 of the element layers 3 and 4 of the wall element 1, so that it is ensured that the half shell 11 of the cargo receiver 10 encloses precisely the cylindrical bushes 9. The cylindrical configuration of the mold parts 10 and the half shell 11 of the cargo receiver 10 allows a rotational movement between the transport anchor and the cargo receiver 10 so that by displacements of the wall element 1 during its movement e no undesirable tensions can build up. In FIG. 3, this connection, by means of a different point of view of the object according to the invention, must be made even more clear. The two element layers 3 and 4 of the wall element 1 are shown enlarged, the element layer 4 - as in the image according to FIG. 2 - is cut out so that the mold part 9 shown on the right appears freely floating, but in fact naturally is firmly anchored in the element layer 4 and from its inner side 5 protrudes into the space 12 in the wall element 1. The load-picking means 10 engages the two precisely on the an axis lying mold portions 9 of the conveyor anchor with its free end half shell 11.1 in practice, the load picking means 10 is manually inserted into the gap 12 and brought into position relative to the mold portions 9. In order that possible position changes of the wall element 1 should not cause damage, the half shell has 11 on the load-picking element 10 transverse walls 13, which fit precisely against the mold members 9, that a displacement possibly occurring during transport between the half shell 11 and the mold parts 9 is prevented. Between the inner sides 5 of the element layers 3 and 4 and the half shell 11 there may be a distance. An unintentional unwinding of the load handler 10 is prevented by means of an arresting pin 14. For the intended release of the load handler 10 from contact with the mold members 9, the arresting pin 14 can be brought to a release position (not shown). The release position can be provided manually, however advantageous is a remote controlled release which is triggered, for example, by a remote control radio signal which electromagnetically causes a change of position of the arresting pin 14. The arresting pin 14 can be replaced by other arresting systems, for example, remotely triggered by string. In FIG. 4 is shown a mounting arrangement 15 with a transport anchor illustrating the installation in the initial phase in the manufacture of a wall element 1. The mounting arrangement 15 comprises two mold parts 9, which form a transport anchor and which are connected precisely to each other at a predetermined distance by means of a cuff 16.
Manchetten 16 til optagelse af formdelene 9, har ved sine to ender en indvendig diameter, som nøjagtigt er afstemt til den udvendige diameter på formdelene 9. Anslag 17 i det indre af manchetten 16 bestemmer den aksiale position, altså den nøjagtige indbyrdes afstand imellem formdelene 9. Længden af manchetten 16 og den indbyrdes afstand mellem anslagene er afstemt til den ønskede vægtykkelse af vægelementet 1. Dette betyder at for forskellige vægtykkelser anvendes forskellige manchetter, medens formdelene 9 for alle vægtykkelser til stadighed har de samme dimensioner. En standardisering af konstruktionselementerne er den fordelagtige følge af denne konstruktionsform. Manchetten 16 består enten af isolerende materiale eller kan efter færdigfremstilling af vægelementet 1 aftages.The cuff 16 for receiving the mold members 9 has at its two ends an inside diameter which is precisely aligned to the outside diameter of the mold parts 9. The abutment 17 in the interior of the cuff 16 determines the axial position, that is the exact distance between the mold parts 9 The length of the sleeve 16 and the distance between the abutments are adjusted to the desired wall thickness of the wall element 1. This means that for different wall thicknesses different cuffs are used, while the molding parts 9 for all wall thicknesses have the same dimensions continuously. A standardization of the structural elements is the advantageous consequence of this structural form. The sleeve 16 either consists of insulating material or can be removed after completion of the wall element 1.
Begge formdele 9 kan ved de udvendige sider 6 af de imod elementlagene 3 og 4 vendende ender være forsynede med forankringselementer 18 (kun vist ved én formdel 9). Yderligere kan afstandsholdere 19 være tilvejebragt, ved hjælp af hvilke formdelene 9 kan positioneres i en forudbestemt afstand fra de udvendige sider 6 på elementlagene 3 og 4. På skitsen ifølge fig. 4 skal grundlinien udgøre overfladen på en forskalling. Montagearrangementet 15 bliver ved fremstillingen af et vægelement 1 positioneret på forskalingsoverfladen 20, i den forbindelse bliver planet for den i givet fald foreliggende armering 21 gennemtrængt. Efterfølgende bliver beton 22 eller en anden afhærdelig støbemasse indfyldt i forskallingsformen og dennes afhærdning afventet. Derefter bliver det afhærdede elementlag 3 på i og for sig kendt måde vendt, positioneret over en yderligere forskalling og efter fyldning af den anden forskalling sænket så langt imod denne, at de på den anden formdel 9 anbragte forankringselementer og afstandsholdere sammen med et delområde af formdelen 9 neddykkes i den endnu ikke afhærdede støbemasse i den anden forskalling. Afstanden mellem det første elementlag 3 og den anden forskalling bestemmer den senere vægtykkelse af vægelementet 1. I fig. 5 er vist en yderligere udførelsesform ifølge opfindelsen, ved hvilken transportankeret atter består af to fortrinsvis metalliske bøsningsformede formdele 9, som til dels er indstøbt i elementlagene 3, 4 og stikker udad ud over disses indvendige sider 5, men er beliggende i indbyrdes afstand. De to formdele 9 er anbragt over et plastrør 48, eksempelvis påstøbt dette, som har en ringere varmeledningsevne end de metalliske formdele 9. Plastrøret 48 kan med sine ender være mere eller mindre optaget eller slet ikke i elementlagene 3, 4. På et lastoptagelsesmiddel i form af en lastkrog 49 befinder der sig en svingbart lejret fjederbelastet sikringsklap 50, med henblik på at forhindre en utilsigtet løsning af lastkrogen 49 fra transportankeret.Both mold members 9 may be provided with anchor members 18 (only shown by one mold member 9) at the outer sides 6 of the ends facing the element layers 3 and 4. Further, spacers 19 may be provided by means of which the mold members 9 can be positioned at a predetermined distance from the outer sides 6 of the element layers 3 and 4. In the sketch of FIG. 4, the baseline should form the surface of a formwork. The mounting arrangement 15 is positioned on the formwork surface 20 in the manufacture of a wall element 1, in which case the plane of the reinforcing arm 21 present is penetrated. Subsequently, concrete 22 or other hardenable casting material is filled into the formwork and its hardening is awaited. Then, in a known manner, the cured element layer 3 is reversed, positioned over a further formwork and, after filling the second formwork, lowered so far against it that the anchoring elements and spacers placed on the second mold part 9 together with a part area of the mold part 9 is submerged in the not yet cured molding compound in the second formwork. The distance between the first element layer 3 and the second formwork determines the later wall thickness of the wall element 1. In fig. 5, a further embodiment of the invention is shown, in which the transport anchor is again comprised of two preferably metallic bushing shaped parts 9, which are partly embedded in the element layers 3, 4 and protrude outwardly beyond their inner sides 5, but are spaced apart. The two mold portions 9 are arranged over a plastic tube 48, for example molded thereto, which has a poorer thermal conductivity than the metallic mold portions 9. The plastic tube 48 may be more or less accommodated at its ends or not at all in the element layers 3, 4. in the form of a load hook 49 there is a pivotally mounted spring-loaded safety flap 50, in order to prevent an unintended release of the load hook 49 from the transport anchor.
