Definitions

  • the invention is based on a shuttering device which is attached to the formwork of the component to be concreted in the manufacture of two components to be concreted at different times, with a narrow, rectangular base shell in plan view and with connecting rods, one end section of which is different from the other End sections are bent approximately at right angles, are inserted in the base shell.
  • room joints also called dilation joints
  • construction joints While the former form a permanent delimitation of one component from another, the latter are only necessary for design reasons; later they are intended to ensure a force-fit connection that largely corresponds to the monolithically cast parts.
  • connecting rods in such a connection.
  • the parts of the connecting rods projecting from the component to be concreted first are bent approximately at right angles and fastened to the formwork or near the formwork in such a way that you can bend it out or back out after stripping.
  • a formwork device as described above, which device is inserted and fastened in the formwork and when concreting the formation of a cavity all around the end sections of the connecting rods to be bent out.
  • Such formwork devices are already known in various designs, u. a. from DE-PS 2 307 073 and from CH-PS 562 376.
  • the first of these prior publications discloses a shuttering device which consists of back, chest and intermediate spacer strips and is made of an elastically deformable material. The manufacture of this device is very expensive, but has the advantage of being easily removed from the first concrete component.
  • the element consists of a foam body in which the end portions of the connecting rods to be bent out are embedded. This solution has been widely used; the scraping out of the foam necessary after the formwork of the first concreted component is time-consuming and associated with the risk that residues which disrupt the positive connection of the subsequent concrete part remain stuck in the construction joint.
  • the invention has for its object to provide an embodiment of the type of shuttering device described above, which retains the advantages of the previously known embodiments without their disadvantages.
  • the manufacture should not only be inexpensive, but should also be able to remove the device which is no longer required after the formwork of the first concrete component has been removed.
  • silicate such as e.g. B. gypsum sawdust mixture or foam concrete
  • additives such as B. bentonite
  • the adhesion of the embedding compound to the component concrete can also be coated with a release agent, such as. B. White lime, avoid easily.
  • a release agent such as. B. White lime
  • elevations are formed on the longitudinal edges of the base shell delimiting the troughs, which elevations adjoin the convex side of the bending sections of the connecting rods protruding from the troughs.
  • the side of the securing strips facing away from the embedding compound and / or the free surface of the embedding compound is provided with a coating consisting of a cement setting retarder.
  • the formwork device described here is used in a formwork 1, which is intended for a concrete component 2, and is used to receive end sections 3b of the connecting rods 3 to be anchored in this concrete component 2 with their U-shaped part 3a.
  • the arrangement of the end sections 3b described above largely determines the shape of two rows of troughs 6 which are formed in the base shell 5.
  • This consists mainly of a thin-walled, thermoplastic material such as. B. polystyrene, e.g. B. formed in the pressing or deep-drawing process, which has open troughs 6, from which the anchoring parts 3a protrude to one of its sides, which is intended to be placed on the component to be concreted.
  • These troughs 6 receiving the end sections 3b are otherwise filled with an embedding compound 7 which was doughy when introduced, but is brittle in the hardened state and does not adhere to the connecting rods or to the molded plastic part, so that it subsequently - as described below - can be easily removed.
  • an embedding compound z. B.
  • the device forms a rigid, dimensionally stable structural unit which can be easily transported, handled and attached to a formwork 1.
  • the element 5 is provided with nail passage holes 9 in its longitudinal edge regions.
  • Elevations 5c, 5d are formed in the latter, one wall part of which - as can be seen in FIG. 2 - lies in the continuation of a curved trough wall part and adjoins the convex side of the bending sections 3c of the connecting rods 3 protruding from the troughs 6. It is thereby achieved that cavities are formed in the concrete of the component 2 behind the bending sections 3c and so that the later bending back of these sections is practically not hindered.
  • the troughs 6 have a cross section which is slightly widened from the bottom to the flat side 5a, which facilitates the shaping of the base shell 5 during its manufacture. Because of the lack of adhesion of the embedding compound 7 to the basic formwork 5, there was a risk that it, together with the connecting rods 3, could fall out of the depressions 6, flat, e.g. B. made of polystyrene, extending across the troughs 6, in the same area to the embedding compound 7 securing strips 8 releasably attached to the wall 5a of the basic circuit 5 forming the flat side, z. B. by spot welding, adhesive connection or by means of rivets, bolts or the like.
  • the troughs 6 could constrict towards the flat side, e.g. B. have a trapezoidal cross-section so that the embedding compound 7 is held in a form-fitting manner in them.
  • security strips 8 can be dispensed with.
  • the adhesion of the embedding compound 7 to component 2 can be achieved by painting the free surface of this compound with a release agent, such as. B. white lime can be avoided.
  • the side of the securing strip 8 facing away from the embedding compound 7 can be profiled, e.g. B. have a grooving, so that the resulting surface parts of the component 2 receive a corresponding profile, which contributes to the roughening of the subsequently obtained construction joint.
  • This side and / or the free surface of the embedding can be used for the same purpose be provided with a coating consisting of a cement setting retarder; the unfinished surface layer parts on the structure 2 can then be sprayed with water after removal of the device.
  • the brittle embedding compound 7 is to be removed, which can be done by administering a few hammer blows on the end sections 3b of the connecting rods 3. Before or after the bending out of these end sections 3b into the straight continuation of the legs of the anchored section 3a, the securing strips 8 which may be used must also be removed.
  • the device is widely used in the production of construction joints in reinforced concrete structures of any kind, e.g. B. when connecting partitions, steps, light wells, intermediate floors, silo ceilings, etc., z. B. on a main wall.
