Definitions

  • the invention relates to a soundproof plug for fastening a screw in a hole in a component
  • pipe clamps When fastening pipes in buildings, pipe clamps are generally used, which are anchored in the building with screws. I plastic dowels are used for holding in masonry, such as
  • the known dowel has various disadvantages, in particular the complex manufacture and the high manufacturing costs associated therewith.
  • the invention has for its object to provide a soundproofing plug, the manufacture of which is simpler and whose production costs are cheaper than in the known plug. This is achieved according to the invention in such a way that the dowel is made in one piece from a rubber-elastic material and that it has a number of elongated thickenings which can be elastically clamped when the screw is screwed into the dowel.
  • the one-piece rubber dowel also has better insulating properties than the known dowel of the same wall thickness, which is combined from plastic and elastomer.
  • the stiffness in the longitudinal direction and the adhesive strength are due to the special shape with massages of the rubber cross-section guaranteed with great certainty at various points.
  • FIG. 1 shows a longitudinal section along the line I - I according to FIG. 3 through a soundproofing plug
  • Fig. 2 shows a cross section along the line II - II through the soundproofing plug according to Fig. 1 and
  • FIG. 3 shows a cross section along the line III - III through the soundproofing plug according to FIG. 1.
  • the soundproofing plug 1 shown in the figures consists in one piece of an elastomeric material, which is advantageously cross-linked, which u. However, it can also be used without a network.
  • the rubber-elastic material In order for the dowel to fulfill its double function (anchoring and sound insulation), the rubber-elastic material must have a hardness of 65 to 90 Shore A. If the hardness were lower, it would be
  • the correct hardness range is regulated in a manner known per se by appropriate choice of the type of rubber, the composition of the mixture and the crosslinking system.
  • the dowel 1 has four longitudinal ribs 2 on the outside, which make it difficult to rotate in the bore.
  • Each outer longitudinal rib 2 is assigned an inner longitudinal rib 3, which projects into the interior 4 of the dowel 1 and is arranged opposite the outer longitudinal rib 2.
  • the two longitudinal ribs 2, 3 of each pair of longitudinal ribs form a longitudinal material thickening in the dowel. Seen in cross section (FIG. 3), the dowel consists of four thickenings 5, which are connected to one another by thinner wall parts 6. are.
  • the massaging of the rubber cross section in the longitudinal thickening 5 has yet another advantage. This is because the dowel is stiffened in the longitudinal direction so that it can be pressed or hammered into the hole in the masonry without bending.
  • the dowel according to the invention ensures that the screw is properly anchored securely.
  • the present dowel is much simpler to manufacture and therefore also cheaper than the two-part dowel mentioned at the beginning with a hard inner core made of plastic and a rubber sleeve.
  • the insulation properties are also better and the anchoring is safer due to the specific shape.
  • An advantage over conventional dowels made of thermoplastic material is that the cross-linked elastomer does not melt in the event of fire like the plastic. The attachment is therefore much safer because the screws cannot fall out.
  • a vent hole 8 is provided on the dowel tip so that no back pressure can arise during driving.
  • OMPI pointed out to make this slightly conical, e.g. B. with a taper of 1 - 5 °.
  • a vibration-damping flange is attached to the screw-in end 10. This flange serves as an intermediate part between the mounting element to be fastened (the pipe clamp) and the wall of the masonry. It is also made in one piece with the rest of the dowel.

Abstract

La cheville anti-bruit (1) est realisee en une seule piece en materiau caoutchouteux elastique. Elle presente une serie de surepaisseurs longitudinales (5) qui, lors de l'introduction de la vis dans la cheville, sont mises sous pression elastique. La cheville sert a fixer des vis ainsi qu'a amortir la transmission du bruit a la construction. La cheville est applicable notamment a la fixation de conduites dans les batiments au moyen de ferrures et de vis.
