Definitions

  • the invention relates to a marking carrier for transport anchors provided with threaded sleeves for precast concrete parts.
  • Such transport anchors are known in various embodiments. They have in common that an anchoring part is connected to a threaded sleeve which is located on one end face on the outer surface of the precast concrete element and in the internal thread of which a lifter can be screwed in, which serves to attach the precast concrete element to a hoist.
  • the anchoring part can be, for example, a reinforcement bar which is inserted through a transverse bore in the threaded sleeve; If the anchoring part has a shaft which is provided, for example, with ribs on the outside or with a plate base at its lower end, then this shaft projects from below into the threaded bore of the threaded sleeve and is fastened there.
  • the shaft has a thread for this at its upper end section that is screwed into the threaded bore of the threaded sleeve. If such transport anchors are cast into a precast concrete element, only the end face of the threaded sleeve is visible from the outside.
  • the object of the invention is therefore to provide a marking carrier with which the threaded sleeves of the transport anchors for precast concrete parts can be marked reliably and clearly in terms of the associated load level.
  • a marking carrier disc has a marking carrier surface on its upper side and is displaceable from a position approximately flush with the end face of the threaded sleeve against spring force into the interior of the threaded sleeve.
  • the marking carrier surface is clearly visible from the outside when the transport anchor is cast in, so that the marking made in the marking carrier surface, for example a number about the load level, is easily recognizable from the outside.
  • An additional marking option is the choice of color for the marking carrier disc; For different load levels, different colors can be used in addition to the number marking.
  • the marker carrier attached in the threaded bore of the threaded sleeve does not interfere with the screwing in of a lifter, because the marker carrier disk shrinks elastically as soon as the lifter is screwed in. When the lifter is unscrewed again, the Marking disc back to its original position.
  • the further advantage is achieved that the threaded bore of the threaded sleeve is largely protected against contamination, because the marking carrier disk largely closes the threaded bore when not in use.
  • the possibility according to the invention of a clearly recognizable load level marking of the transport anchors in the concreted-in state makes it possible to build lifters of increased load capacity and to bring them onto the market which have the same thread diameter as previous lifters of a lower load level.
  • the marking option according to the invention reliably prevents an accident from the use of a lifting device with a load level that is too low.
  • the marker carrier thus leads to a substantial increase in security.
  • the marking carrier disc is connected to an elastically deformable bellows, which is connected to the internal thread of the threaded sleeve in a form-fitting or frictional manner.
  • the bellows is a particularly easy to manufacture and particularly insensitive to contamination and clogging elastic element.
  • the marker carrier plate and the bellows are preferably made in one piece from plastic. As a result, the attachment of the marker carrier plate to the bellows presents no difficulties; in addition, the surface at the connection point of the marking carrier plate with the bellows is smooth and tightly closed, so that no impurities can penetrate at this point.
  • the bellows at its lower end has a circumferential edge that can be inserted into the threaded bore of the threaded sleeve under radial elastic prestress having.
  • the bellows remains connected to the threaded bore at its lower end in all deformation states and in particular also in the elastically deformed state, so that on the one hand it is easily deformable, but on the other hand it cannot fall out even in the case of impact loads.
  • the marking carrier 1 shown in FIG. 1 is inserted into a threaded bore 2 of a threaded sleeve 5 which is screwed onto a transport anchor 6.
  • the transport anchor 6 is cast into a precast concrete part 7; the end face 8 of the threaded sleeve 5 lies in an outer face 9 of the prefabricated concrete part 7.
  • the marker carrier 1 is designed as a one-piece plastic part and has at its upper end a marker carrier plate 10 lying approximately flush with the end face 8 of the threaded sleeve 5 in the unloaded state, the upper side of which is a marker carrier Surface 11 forms, on which a mark 12 (FIG. 2) designating the load level is attached, in the exemplary embodiment shown the number "4.3".
  • the marker carrier plate 10 is integrally connected to an elastically deformable bellows 13, which is also made of plastic and, like the marching carrier disc 10, can be displaced with play in the threaded bore 2.
  • the bellows 13 has a circumferential edge 14 inserted under radial elastic prestress into the threaded bore 2 of the threaded sleeve 5 and frictionally connected to the threads, which holds the marker carrier 1 in the threaded bore 2 and prevents it from falling out.
  • the peripheral edge 14 thus forms an anchoring for the marking carrier 1 in the threaded sleeve 5.
  • the marking carrier shown in FIGS. 3-6 is intended to be inserted into the threaded bore 101 of a threaded sleeve 102 shown in FIG. 7, which is part of a transport anchor for a precast concrete part 103.
  • the threaded sleeve 102 is connected to a ribbed anchor shaft 104 which has one at its upper end has upset threaded portion 105 which is screwed into the threaded bore 101.
  • the transport anchor formed in this way is cast into the precast concrete part 103 such that only the end face 106 of the threaded sleeve 102 is visible from the outside.
  • the marking carrier 107 (FIG. 3) inserted into the threaded bore 101 has a marking carrier disk 108 made of plastic, the upper side of which forms a marking carrier surface 109, on which a marking 109a indicating the load level is attached, in the exemplary embodiment shown the number "2.5" (Fig. 5).
  • the diameter of the marker carrier disk 108 is selected such that the marker carrier disk 108 fits into the threaded bore 101 with play and can be moved therein.
  • the edge of the marker carrier disk 108 is bent downward and engages around the uppermost spring turn of a metallic compression spring 110 designed as a truncated cone spring.
  • the lower edge of the marker carrier disk 108 is slightly deformed inward so that it securely holds the upper turn of the compression spring 110.
  • the lower end of the compression spring 110 is connected to an anchoring washer 111 made of plastic.
  • the anchoring disk 111 has on its upper side a projecting button 112 on which the lowest spring turn of the compression spring 110 engages and holds.
  • the anchoring washer 111 (FIG. 6) has a plurality of radially projecting ones Provide locking tabs 113 which snap into the threads of the threaded bore 101 when the marker carrier 107 is inserted into the threaded bore 101.
  • the anchoring disk 111 lies against the bottom of the threaded bore 101, which is formed by the upper end of the threaded head 105 of the anchor shaft 104.
  • the marking carrier is dimensioned such that the marking carrier surface 109 is approximately flush with the end surface 106 of the threaded sleeve 102 in the unloaded state, as shown in FIG. 7.
  • the marking 109a is thus clearly visible from the outside.
  • the marking carrier disk 108 is executed in a color which is assigned to the respective load level.
  • the compression spring 110 of the marking carrier 107 is compressed and takes on the shape shown in FIG. 4.
  • the marking carrier 107 has only a very small axial length, so that the screw-in depth required for the lifter is largely available without restriction.
  • the spring windings of the frustoconical compression spring 110 can approximately take the form of a spiral when the compression spring 110 is fully compressed.
  • the compression spring 110 can also be designed as a cylindrical spring.
  • FIGS. 8 and 9 embodiments of the marking carrier 107 are shown, in which the marking carrier shines be 108, the anchoring washer 111 and the compression spring 110a and 110b are made in one piece from plastic.
  • the compression spring 110a according to FIG. 8 has a plurality of spring sections 110c which are connected to one another at an acute angle and which close together when the compression spring 110a is compressed in the manner of a fan fold.
  • the marking carrier 107 represents a plastic part that is particularly easy to produce because the tools that form the compression spring 110a can be pulled apart on both sides during molding.
  • the compression spring 110b consists of several buckling spring bars 110d, which are slightly curved in the unloaded state.
  • the buckling spring bars 110d are slightly curved inwards and curved in an S-shape in the circumferential direction, so that they collapse closely when the compression spring 110b formed in this way is subjected to pressure.
  • FIG. 10 Another embodiment of the marking carrier 107 is shown in FIG. 10.
  • the compression spring 110e connecting the marking disk 108 and the anchoring disk 111 is formed by an elastic foam body which can be compressed when the marking carrier disk 108 is pressed down into the position indicated by broken lines in FIG. 10.
  • the plastic body 110e can be glued or welded to the marking carrier disk 108 and the anchoring disk 111.
  • the lower section of the foam body 110e forms the anchoring disk 111.
  • a hardening adhesive layer with which the foam material body 110e or a compression spring of another embodiment is fixed in the threaded bore 101, the anchoring washer 111 can form.
  • the anchoring part connected to the threaded sleeve 102 can also be a reinforcing bar 114, which is curved, for example, and inserted through a transverse bore in the threaded sleeve 102.
