Definitions

  • the present invention relates to a spacer for Formwork according to the preamble of claim 1.
  • spacers are used when creating concrete walls arranged between the formwork on both sides and the Formwork using threaded spindles passing through the spacers held together. After creating the concrete wall the formwork is removed and the threaded rods that the Push through spacer, pulled out. The remaining ones Through holes must be closed later.
  • the spacers for formwork that are of interest here are those that penetrate the concrete wall to be created Have spacer tube, which in the created concrete wall remains.
  • Such a spacer for formwork with one Spacer tube is known for example from DE-A-34 33 575.
  • the spacer shown here only consists of a cladding tube serving as a spacer tube, in which a plastic pin with a core of preferably fiber-reinforced Cement is hammered in.
  • a spacer forming the preamble of the claim for formwork is known from AT-A-371 877. It is a spacer for formwork with a cover comprising one remaining in the concrete wall Spacer tube with at least one on the outer visible side Concrete wall on the formwork that comes to rest on the support cone and a cover for closing the opening in the Concrete wall.
  • the support cone and the spacer tube can be plugged together designed.
  • the support cone encompasses this Spacer tube at the end.
  • the support cone is preferably off Made of plastic and has anchoring in the wall outward radial and axial ribs. Of the The support cone is hollow and has a defined inner opening that can be used retrospectively Cover corresponds.
  • the invention solves this problem by means of a spacer for formwork with the features of claim 1.
  • FIG. 2 the finished concrete wall B is shown in section. All that remains of the actual spacer Spacer tube 1 in the concrete wall B.
  • the support cones 2 are also removed.
  • the support cone 2 the following still is described in more detail, thus serves as a fitting and in the An opening 3 remains corresponding to the outer shape of the wall Support cones 2.
  • An insertable pin 4, which into the Distance tube 1 reaches, is then pressed in. Of the insertable pin 4 is connected to the cover 5.
  • the cover closes the opening 3 with the correct shape the support cone was formed as a molded part in the concrete wall is.
  • the support cone 2 is advantageously made of plastic manufactured and has a smooth outer surface without handles and recesses.
  • the support cone 2 consists of the actual cone body 20, at the base of an annular Collar 21 is formed. This collar 21 defines the shape and size of the actual cover 5.
  • On the cover surface 22 a conical pin 23 is placed on the cone 20, whose diameter is the inside diameter of the spacer tube 1 corresponds.
  • the diameter of the top surface 22 is larger than the diameter of the cylindrical pin 23 and corresponds at least approximately the outer diameter of the spacer tube 1. So remains of the top surface 22 of the cone body 20th only one concentric around the cylindrical pin 23 extending annular shoulder 24.
  • a support cone 2 designed in this way can be used on both sides insert into the spacer tube 1 and can on the construction to be delivered. Thanks to the annular collar 21 the support cone 2 can also be easily attached to a formwork S. This is preferably done by using the support cone 2 nailed to the formwork S. Accordingly, the ring-shaped collar 21 through holes for the nails exhibit.
  • the support cone 2 serves only as a molded part and after the creation of the concrete wall B no more function takes over, it can also be designed as a reusable part be. As a reusable part, it can be particularly dimensionally stable and be made stable and therefore extremely thick-walled or even be made as a full body. Such a support cone is particularly dimensionally stable and is also under high pressure not deformed. Accordingly, the opening 3 is always accurate in shape.
  • FIGS. 1 and 2 A first embodiment is shown in FIGS. 1 and 2 evident.
  • the variant shown here consists of essentially of a hollow cylindrical body 40, which here is completed by a terminal partition 41.
  • the Partition wall 41 is penetrated by a threaded hole 42 in that a threaded rod 43 is screwed in.
  • the threaded rod 43 is one-sided by a flattening 44 to a kind Broadened plate on which the actual cover 5 is welded on.
  • the hollow cylindrical pin body 40 is preferably made of plastic and in the area that in the spacer tube 1 protrudes with circumferential retaining ribs 45 provided.
  • the cover 5 is preferably one Manufacture non-corroding metal plate.
  • the metal plate and the threaded rod made of stainless steel or other non-corroding Metal alloys exist.
  • the corrosion can also prevented by appropriate galvanic coating will.
  • the outer surface of the cover 5 can also with a corresponding to the desired aesthetic effect color-coated coating.
  • a synthetic resin varnish or enamelling can be used here.
  • sticking one is not excluded mineral platelets, for example made of marble or Granite.
  • a fair-faced concrete wall is not necessarily completely flat, but has certain bumps, it makes sense to the back of the cover 5 a rubber-elastic disc 46 to provide for the seal.
  • the rubber-elastic disc 46 can be glued to the back of the cover 5 or between the hollow cylindrical pin body 40 and the cover 5 only be pinched when screwing the hollow cylindrical pin body 40 on the threaded rod 43.
  • FIG. 4 to 6 is a variant of the insert Pin 4 shown.
  • This insertable pin 4 also has a hollow cylindrical pin body 40 with a terminal Partition 41 on.
  • the pin body 40 is in turn on the outside provided with radially projecting retaining ribs 45 for non-positive mounting of the pin in the spacer tube 1.
  • this insertable pin 4 is made of plastic. in the In contrast to the previously described version, however, none fixed over a threaded rod with the pin body 40 connected cover. Rather, here is the cone body 40 connected to a receptacle 50. In the example shown is the receptacle 50 in one piece with the hollow cylindrical Pin body 40 made.
  • the sealing partition 41 can thereby moved from the back so far inward be arranged so that the hollow cylindrical pin body 40 the other end is closed.
  • This case forms the receptacle 50 together with the partition 41 a kind Plate 51.
  • This plate 51 has a circumferential, upstanding edge 52 so that in the receptacle 50 at least approximately a cover 5 in the form of a loose plate 53 can be inserted.
  • a radial can be formed on the upstanding edge 52 inward retaining lip 54 may be provided.
  • the cover 5 can be used as a loose plate 53 in the way Simply press in holder 50.
  • the recording 50 designed in two parts.
  • the plate 51 of the recording 50 is in turn provided with an upstanding edge 52, however, here is a loose retaining ring 55, which over the rising edge 52 can be pressed and then positively is held by means of a notch 56 in the outer surface of the rising edge and a positive in this notch matching locking rib 57 on the retaining ring 55th
  • a cover 5 can be shaped insert a plate of any material.
  • a circumferential Sealing lip 58 provided in the non-installed state protrudes obliquely from the plate-shaped surface of the receptacle 50 and when installed on the collar-shaped recess 30 of the opening 3 lies sealingly.
