Definitions

  • the present invention relates to a cable loop insert for the connection of prefabricated concrete parts, in particular for the end face connection of concrete wall elements to one another, consisting of a closed or an open-ended, spring-elastic cable loop and an insert serving as a molded core, which closes the closed part that is elastically angled onto the formwork during the production of the precast element Encloses the head section of the rope loop.
  • holding devices are known in which eyelet-shaped holding elements protrude from a recess determined by an insert shell part in the composite surface of the precast concrete parts or molded parts.
  • the eyelet-shaped holding element can be an erectable steel bracket or an elastic wire loop, which is accommodated in an insert shell part in the form of an unstructured plastic housing.
  • the holding element in the form of an erectable steel bracket or an elastic wire loop is fixed in its position by a nose-shaped attachment in the insert shell part.
  • This insert known from the prior art essentially has two functions.
  • the holding element On the one hand, it is intended to enclose the holding element in a sealing manner, so that the concrete mass flowing in during the production of the molded molded parts does not come into contact with the holding element.
  • the second and probably just as important function is the fixation of the holding element within the insert shell part, because the holding element should be fixed within the sealing and protective enclosing molded part in an angled or bending shape, which is an embodiment or an order of magnitude made of the insert part necessary, which extended from the narrowest radius of curvature of the holding element in both directions of the holding element so that the element was fixed in the desired radius of curvature.
  • the insert shell part had to be designed to be disproportionately large and stable, which, as already mentioned, appeared to be too costly for the actual intended use within molded concrete parts.
  • a rope transport anchor with a non-positive connection of two adjacent rope areas to form the rope loop is also known, which has a dimensionally stable unwinding device of the rope in the form of a sleeve pressed with the rope.
  • the cable areas on both sides of the sleeve can be fixed in a certain angular position to be determined. This angular position once reached can only be changed again by applying a large mechanical load.
  • the invention lies in the fact that a retaining bracket is additionally arranged in the insert shell part, which deforms and pre-stresses the cable loop in a flexurally elastic manner and fixes it at least essentially at a right angle without stressing the insert shell part with these mechanical stresses.
  • the solution according to the invention consistently separates the protective function or the enveloping function from the holding and fixing function.
  • the actual insert shell part can sealingly enclose the head section of the rope loop both on the concrete side and on the formwork side and prevent the casting compound from penetrating into the head section of the rope loop without it having to be made of expensive high-quality and high-strength material.
  • the support bracket additionally arranged according to the invention in the insert shell part receives the entire rope loop in an elastically deforming manner and fixes the rope loop completely without the involvement of the insert shell part.
  • the head sections of the rope loops that are to be erected in the bonded position must have a prescribed length for the secure bond.
  • the right-angled fixation on the formwork side is necessary in order to anchor the entire rope loop insert firmly in the concrete during the manufacture of the precast concrete elements or wall elements by pouring.
  • the head section of the rope loop is angled and fixed to the formwork during manufacture of the finished parts.
  • the rope loop can be closed on the concrete side or open-ended and can even be equipped at its ends with additional angled end parts and reinforcing elements for better anchoring in the molded part.
  • the head section which erects itself spontaneously by elastic resetting after being released from an abutment in the holding bracket is designed as a loop.
  • a cross bolt between the side surfaces of the short U-profile section fixes and clamps the inserted rope loop between the abutment for the rope loop head section and the bottom surface of the U-profile.
  • this clamping of the cable loop into the support bracket is carried out in such a way that the entire cable loop is inserted from its flat configuration with bending into the support bracket, an angled section of the head portion of the cable loop being angled onto the abutment. If the cable loop is inserted and angled in the holding bracket in this way, the cable loop is fixed or clamped by the cross bolt, which is inserted for this purpose or shot into the U-profile.
  • the rope loop preassembled in this way is now fixed in a right-angled, angled shape and is then inserted into an insert shell part.
  • the angled head section of the rope loop is covered by the insert shell part and lies against the formwork side, the longer part of the rope loop body is fixed in such a way that it protrudes into the prefabricated concrete part.
  • the insert shell part takes up both the head section of the rope loop and the support bracket and encloses both both formwork and concrete sealing.
  • the insert shell part is configured so that it forms a mold core on the concrete side to form a locking cavity in the precast concrete part.
  • the insert shell part is configured differently in its longitudinal dimension and also in its concrete-side dimension, depending on the size and shape of the cavity to be formed, as the mold core for forming this cavity in the precast concrete part. If the insert shell part only has to fulfill an enveloping function, it is preferably designed as a cheap and easy-to-produce blister pack.
  • the formwork-side part of the insert shell part or the blister pack has, for example, a smooth edge and outer edge area onto which a protective plate provided with a guide can be pushed.
  • the flat formwork-side cover of the insert shell part is detachably clipped onto this shell part.
  • the insert shell part can be equipped with mounting brackets or mounting openings for fastening to the formwork.
  • These mounting brackets or openings are advantageously arranged on the smooth outer edge regions or opposite one another on the smooth edge regions or on or in molded-on tabs.
  • the insert shell part according to the invention which has an additional retaining bracket, has the advantage that, on the one hand, the retaining bracket, as a relatively small, compact construction, fixes the rope loop at a right angle, whereby this preassembled rope loop retaining part is received by the insert shell part and only has to be enveloped by it in a sealing manner.
  • the material used for the insert shell part can be an inexpensive blister-like profile-stiffened plastic capsule.
  • the cable loop insert part essentially consists of a cable loop 2 with a head section 3, a support bracket 4 with a bolt 5 and an all-encompassing insert part 1, which in turn is formed in two parts and consists of an insert shell part 11 and a flat cover 12 on the formwork side.
  • the insert shell part 11 and the cover 12 are additionally supported against one another by profile elements 13.
  • the bracket 4 is designed as a robust and compact U-profile section, a manufactured by the injection molding process Plastic molding.
  • the support bracket 4 receives the rope loop 2 elastically deforming and at least essentially at a right angle.
  • the two free ends of the wire rope protruding into the concrete part are positively connected to one another to form a loop.
  • the head section 3 of the rope loop 2 is in any case designed as a closed loop.
  • the support bracket 4 is a short U-section and consists of a bottom surface 7 and an abutment 8 which at least partially closes the U-section.
  • the U-section is open on the concrete side with an abutment 8 on the formwork side for the head section 3 of the cable loop 2.
  • a cross pin 5 Between the opposite U-profile section 10 extends a cross pin 5. This cross pin 5 clamps the inserted cable loop 2 between the formwork-side abutment 8 and the bottom surface 7 of the U-profile.
  • the cross bolt 5 is expediently mounted after the cable loop 2 has been inserted into the holding bracket 4.
  • the abutment 8 of the head part 3 of the rope loop is slotted in the middle or has a central through-channel or a central recess in which the head part 3 of the rope loop can be erected from the bent or angled position to its position intended for the manufacture of the precast element composite .
  • This central recess extends essentially through the entire abutment.
  • the bottom surface 7 of the U-profile which extends at least substantially at right angles to the abutment 8, has reinforcing ribs 9 which increase in the direction of the formwork side. These reinforcing ribs 9 are configured as a function of the diameter and consequently as a function of the size of the bending forces to be absorbed.
  • the reinforcing ribs 9 are formed in an extension of the central recess in the abutment, on the outside of the bottom surface 7 of the U-profile.
  • the inside of the bottom surface 7 of the U-profile is equipped with guide grooves 6 which receive the closed part of the rope loop which projects into the concrete.
  • These guide grooves 6 have essentially the task of the rope loop in the predetermined angle and in the central position in the bracket fix the trestle and thus prevent the rope loop from twisting or slipping out of the specified position. They also serve to seal the interior of the insert against the penetration of casting compound when pouring the precast concrete parts.
  • the rope loop which is clamped and fixed in this way, is inserted into the insert shell part to produce the precast concrete elements or concrete wall elements.
  • the insert shell part 11 is dimensioned such that it surrounds the head section 3 of the rope loop 2 and the holding bracket 4 in a sealing manner on the concrete side.
  • the insert shell part has a profiled edge onto which a protective plate provided with a guide can be pushed or clipped on.
  • the manufacture of the precast concrete elements or wall elements is carried out in such a way that several pre-assembled cable loop insert parts are attached to the formwork at a distance from one another, if necessary even only placed on or placed on the formwork, the prepared formwork body is then poured out with concrete and thereby the rope loops are cast in and thus firmly anchored. After the concrete parts have hardened, the formwork is removed. The head sections of the rope loops, which are encased in the insert shell part or in the blister pack, remain on the composite sides.
  • the cover is first removed from the insert shell part 11 and then the head section 3 of the rope loop 2 is released from the abutment 8 of the support bracket 4 by a short compression and guided into its intended functional position through the centrally open recess in the abutment 8 .
  • a short compression and guided into its intended functional position through the centrally open recess in the abutment 8 .
  • Often guiding through this open recess in the abutment is not necessary at all, since the release of the locking mechanism automatically causes the spring-elastic reinforcement elements or the rope loops to jump out of the tensioned into the relaxed free position.
