Zum Aufladen eines armierten Betonkörpers 1 von rechteckförmiger v/annenartiger Gestalt, z.B. als Bodengruppe eines Gehäuses; auf ein Fahrzeug bzv;. zum Abladen des Betonkörpers mit einem entfernten Aufstellungsort des Gehäuses mittels eines Hebezeuges weist der Betonkörper 1 im Bodenbereich IA an mehreren verteilten Stellen eingegossene und mit der Armierung 2 verankerte Gewindebuchsen 3 auf, die bündig mit der Außenwand abschließen und zur Aufnahme von schraubbaren Anhebevorrichtungen dienen. Jede Anhebevorrichtung ist mehren teilig aus üblichen Elementen gebildet und kann demnach am Aufladeort des Betonkörpers notfalls auf einfache Weise hergestellt werden. Hierzu werden für jede Anhebevorrichtung nur eine in die Gewindebuchse 3 einschraubbare Kopfschraube 4, insbesondere eine genormte Sechskantschraube, eine von der Schraube 4 durchdrungene kreisförmige Druckscheibe 8 zum Abstützen eines die Schraube 4 mit axialem Zwischenraum umgebenden Tragrohres 7 sowie ein von der Schraube 4 durchdrungenes und quer zur Schraubenlängsachse über das Tragrohr 7 vorstehendes Sicherungsteil 6 für das Verbindungsglied 9 benötigt, das in Form einer Seilschlaufe um das Tragrohr geschlungen ist und durch das Sicherungsteil 6 am Abrutschen gehindert wird.. Das Sicherungsteil 6 kann aus einem über die Seilschlaufe 9 hinausragenden flachen Riegel bestehen^ der die Stirnseite des Tragrohres 7 allseit ig überragt.. Der Schraubenkopf 4A greift gegebenenfalls über eine Unterlegscheibe 5 am Sicherungsteil 6 an undFor charging a reinforced concrete body 1 of rectangular v / annen-like shape, e.g. as the floor pan of a housing; on a vehicle or. for unloading the concrete body with a remote installation location of the housing by means of a hoist, the concrete body 1 in the floor area IA Threaded bushings 3 which are cast in at several distributed points and anchored to the reinforcement 2 and which are flush with complete the outer wall and serve to accommodate screwable lifting devices. Each lifting device is multiple formed in part from common elements and can therefore be placed at the loading point of the concrete body in a simple manner if necessary getting produced. This is done for each lifting device only one head screw 4 that can be screwed into the threaded bushing 3, in particular a standardized hexagon screw, a circular thrust washer 8 penetrated by the screw 4 for supporting the screw 4 with an axial Support tube 7 surrounding the space, as well as one penetrated by the screw 4 and transverse to the screw's longitudinal axis over the support tube 7 protruding securing part 6 for the Link 9 is required, which is in the form of a rope loop is looped around the support tube and is prevented by the securing part 6 from slipping. The securing part 6 can consist of a flat bar protruding beyond the rope loop 9, the end face of the support tube 7 on all sides ig protrudes ..
