Definitions

  • the invention relates to a joint anchor consisting of the actual dowels and a multi-part plastic cover.
  • a significant distinction between neighboring fields or the joints separating them can be made whether it is a room joint (manufactured using formwork Fuge), where the neighboring fields have a have a certain distance from each other or by a Dummy joint, which during the curing and thus the Shrinkage of the concrete, through appropriate measures designated places is initiated and essential has smaller widths than the space gap.
  • the dowels themselves have an increasing number in the course of their use Experience improvement, especially what their wrapping concerns. Were the first such dowels in the in the early interwar period still simply embedded in bitumen and especially when used at airports, roadways and the like are exposed to corrosion after a very short time, as early as 1937 was disclosed in US 209 50 61 A, that the dowels would have to be accommodated in sleeves Area of the joints has a corresponding longitudinal extensibility should have. This elasticity, a division of the Overlap sleeves, makes use only possible in room joints. A variant with an am Equal arranged, radial bead and pushed there spherical cover with openings for the dowel intended for use in crunching joints.
  • a shear reinforcement is known from DE 35 39 287 A, in which a round bar or round bar from a multiple in separate plastic sleeve is coated. This one too Dowel structure provides no protection against occurrence of corrosion.
  • EP 0 633 356 A corresponding to DE G 931 01 29.5 U, discloses a joint dowel made up of a basic element Round metal and a plastic shell, the Plastic cover as a closed unit in the axial direction longer and larger in diameter than the basic element and wherein the plastic casing has at least one crumple zone having.
  • This joint anchor is considered suitable for expansion, Cut, movement or day joints called, however makes the need for a crumple zone in the plastic shell to provide this dowel only for Room joints are suitable because the crumple zone is at least essentially must lie outside both parts of the concrete ceiling, to perform their function.
  • the invention aims to create such a joint dowel and achieves these goals by the features of claims 1 and 10.
  • the measures according to the invention ensure that each of the plastic sleeves of an inventive Fugendübels form-fitting from that of the two concrete fields, in which it is located, held and reliably participate in the movement of this concrete field.
  • the plastic tube is preferably made of Silicone material (also called silicone, in particular as silicone rubber) and is able to endure extreme elongations, even if these repeat often and often.
  • the preferred silicone material is a high polymer, cross-linked polysiloxane, optionally with inorganic Fillers.
  • Such a product is from Rehau available under the name RAU-SIK.
  • the plastic cover consists of two identical structures Parts and the protruding or recessed surface parts are preferred along at least three four, possibly more, in the axial direction extending ribs arranged.
  • these ribs end on the Side of the open casing ends at a distance from the casing ends, so that the plastic hose on a smooth cylindrical Shell surface can be plugged in, according to a preferred embodiment, the correct axial position the plastic hose through an outwardly projecting circumferential shoulder is marked and saved.
  • Joint dowel consists of two plastic sleeves 2, the a bottom 3 in one piece with them at one end have trained and end up open at the other end.
  • Ribs 5 are not smooth on their outer surfaces, but have protruding areas 6 and recessed areas Areas 7 on. These ribs 5 extend starting from the bottom 3 over the greater part of the length of the Plastic sleeve 2, but end at a distance from the open end 8 of the plastic cover 2.
  • Plastic hose 10 Essentially over the entire axial extent between the two ring shoulders 9 of the two plastic sleeves 2 extends in the fully assembled state Plastic hose 10. This plastic hose is in the assembled state, as shown in FIG. 1, slightly stretched in the circumferential direction (elastic pretensioned) and is therefore close and tight on the outer surface the plastic sleeves 2 in the area between the shoulders 9 on.
  • the plastic tube 10 is preferably made of silicone or another plastic material with great elasticity and can therefore be opened when the joint (if he is not used in the area of a room joint) the small then free axial area very large Endure changes in length. Silicone or other used Material is also capable of such changes in length and their reshaping almost any number of times endured, the material is durable in this regard.
  • a joint anchor according to the invention can also be designed differently than shown: This is how the Number of ribs 5 can be changed, the bottom 3 the plastic sleeves 2 are glued or welded, this bottom can be cup-shaped and over then pushed the plastic sleeve formed as a tube be, whereby the connection by elastic Deformation, by providing appropriate elastic too bending components (barb-like) can be done.
  • the annular shoulder 9 can be designed differently than shown be, or be omitted at all, which makes the Ends of the ribs 5 or other projecting elements of the Plastic sleeve 2 fixation and adjustment of the plastic hose 10 take over, with suitable assembly tools can on the arrangement of such adjustment aids at all to be dispensed with.
  • a plastic rod or a metal tube or a combination thereof is used as the actual dowel 4, it also being possible to provide a plastic coating on a metal rod.
  • the reason for this is that the density of the entire joint, including plastic sleeves and plastic hose, is at least essentially (between 0.8 times and 1.25 times) matched to the density of the wet concrete and in a variant between 2500 kg / m 3 and 3700 kg / m 3 is to prevent the joint anchor in the still wet concrete, especially during its compaction by vibration, to sink to the floor. This measure is particularly important for joint plugs laid individually in the still wet concrete.
  • the joint anchor 1 is preferred, as in 2a and 2b shown schematically, as follows assembled:
  • the plastic hose 10 is briefly over the Plastic sleeves 2 pushed and then the dowel 1 on a board-like workstation or a mounting plate 14 between two side elevations 12, one on top of the other approach, inserted (position I). Then he will in the direction in which the two side elevations 12 run towards each other, rolling forward, in which Area in which the plastic hose 10 is located, a recess or groove 13 is provided.
  • the two plastic sleeves 2 in the middle pushed and deformed the plastic tube 10 bellows-like (position II).
