Definitions

  • the invention relates to sleeves or mandrels to be installed in a concrete component for receiving a mandrel or a sleeve of an adjacent component for the transmission of transverse forces between the aforementioned components, the sleeve or the mandrel having a perforated fastening plate by means of which they attach to the formwork of the concrete component are to be fixed.
  • Such sleeves and mandrels are known for example from US-PS 2 194 718 and EP-PS 32 105.
  • the basic problem here is to fix the sleeve or the mandrel in a desired position before the concrete component is poured.
  • the sleeve is preferably fixed and the mandrel is switched by partial insertion into the sleeve.
  • EP-PS 32 105 this is done with the aid of a fastening plate which is attached to the open end of the sleeve and which is nailed to the inside of the formwork before the concrete is poured in.
  • the mandrel for the adjacent component is then inserted, projecting into the neighboring circuit with a desired length.
  • the metal mounting plate can be easily connected to it.
  • the object of the present invention is to develop a simple but reliable connection between the sleeve on the one hand and the associated holding plate on the other.
  • the holding plate should not impair the bond between the sleeve and the surrounding concrete, so that at least the risk of failure described above is excluded.
  • the holding plate is anchored to the separately produced sleeve by means of pins projecting from the rear.
  • the pins can either run on the outside of the sleeve and be glued to it there, or be anchored in corresponding holes in the sleeve their open end are arranged distributed over the circumference.
  • the bond between the pins and the holding plate can be improved further in that the pins are profiled on the surface, in particular have transverse ribs.
  • the pins can either be rigidly attached to the holding plate. If they are made of steel, they are expediently welded on. However, it is also within the scope of the invention to provide the pins in the form of separate components by having a head at one end, while at the other end they are inserted through bores in the holding plate and fixed on or in the sleeve. With regard to the latter variant, it is particularly advantageous to design the pins as clamping pins, optionally radially elastic, or as grooved pins which are driven into corresponding bores in the sleeve after the holding plate has been placed on the end wall of the sleeve.
  • the clamping pins expediently have a countersunk head and the associated bores in the holding plate are correspondingly conical, so that the head of the clamping pin is aligned with the holding plate almost without protrusion. This favors their attachment to the formwork.
  • connection of the holding plate and its pins with the sleeve described above is of course equally suitable for fastening the holding plate to a bearing body surrounding the mandrel.
  • the only difference is the position of the holding plate, because it is no longer to be positioned on one end face but in the central region of the mandrel. Since the mandrel is usually made of steel, the holding plate can also be welded directly to the mandrel. Another connection, in particular a clamp connection, is also possible.
  • the holding plates and / or the sleeves / mandrels with leveling marks. As a result, they can be positioned at a certain height level in a highly precise and simple manner and then nailed to the formwork boards.
  • These leveling marks are preferably formed by lateral notches on the edges of the holding plate, namely at the level of the sleeve or mandrel center, but can also be produced by ribs or other projections on the sleeve.
  • Another particularly expedient embodiment of the invention consists in that the sleeve is provided on the inside or outside and / or the mandrel on the outside with a sound-absorbing material, in particular an elastomer.
  • the sleeve 1 consists of a cylindrical body which has a through bore 2 in its center and a plurality of longitudinal ribs 3 on its outer circumference. It is preferably made of fiber concrete, but can also consist of other materials, such as hard concrete, in particular of epoxy resin.
  • a holding plate 4 which is preferably made of metal and has a bore in its center which is at least as large as the bore 2.
  • the mounting plate has some holes in the edge area so that it can be nailed together with the sleeve 1, the fastening of which to the holding plate will be discussed in more detail below, on a formwork not shown in the drawing can.
  • the holding plate 4 bears a marking 4 'on two opposite vertical sides, namely at the center of the bore 2. This allows the sleeves to be easily leveled in height before nailing to the formwork board.
  • Figure 1 shows that a mandrel 5 is inserted in the bore 2 of the sleeve 1. It is dimensioned such that it can be slid in the bore 2 and that its length largely fills the sleeve 1 and a similarly long part protrudes from the sleeve.
  • the end of the sleeve 1 opposite the holding plate 4 is generally closed by a plastic plug so that no concrete can penetrate into the bore 2 there.
  • Figures 2 and 3 show the attachment of the holding plate 4 to the sleeve 1.
  • the sleeve 1 has some axial bores 1a extending from the end wall, in which pins 4a of the holding plate 4 are anchored. This can be done by jamming or gluing.
  • the pins 4a can be welded to the holding plate 4, in particular if the pins are metal. Instead, however, separate pins 6 can also be used, which are inserted through conical bores in the holding plate 4 and hold the holding plate flush by their countersunk head 6a, as is shown in the lower section of FIG. 2. Appropriately, these are radially elastic Clamping pins, they tighten or hook themselves when driving into the sleeve. This solution is particularly inexpensive because neither welding nor gluing is required.
  • Figure 3 illustrates the position of the holding pins 4a and 6 in the region of the longitudinal ribs 3 of the sleeve. If pins 6 with a strong clamping effect are used, it is advisable, however, to move the bores 1a more into the sleeve interior in order to prevent the sleeve material from bursting open locally.
  • Figure 4 shows another positioning of the retaining pins 4a.
  • the holes 1a in the sleeve can be dispensed with because the pins 4a are positioned along the outer circumference of the sleeve. In this case, they are connected to the sleeve by a plastic adhesive.
  • FIG. 5 shows a sleeve similar to that of FIG. 1, but with a larger bore 2.
  • the annular gap opposite the mandrel 5 is covered with a material made of sound-absorbing material, in particular an elastomer 7.
  • the lining 7 expediently extends almost over the entire length of the bore 2 in order to bring about a large-area support with respect to the mandrel 5.
  • FIG. 6 shows an alternative in which the sound insulation is provided on the outside of the sleeve.
  • the sleeve 10 is made of hard concrete, but has an approximately rectangular cross section and is surrounded on the outside by a matching rectangular steel tube 11.
  • an elastomer plate 8a and 8b is arranged on the bottom and top of this steel tube 11.
  • the two plates can be glued to the steel tube or held by wrapped tape or otherwise attached.
  • a horizontal circumferential adhesive tape 12 is shown, which runs around all vertical sides of the sleeve including the holding plate 4 and has a corresponding opening in the region of the bore 2.
  • This adhesive tape expediently consists of bitumen, polyurethane or another sound-absorbing material, so that the sleeve not only experiences a sound decoupling from the surrounding concrete component laterally through the plates 8a and 8b, but also laterally.
  • the band 12 also holds the two sound-absorbing plates 8a and 8b.
