Definitions
- the invention relates to a joint dowel consisting of the actual dowel and a multi-part plastic casing.
- Such joint dowels in which the actual dowel is made of steel are used in concrete ceilings, for example from roads, airstrips, or the like. used to prevent the vertical offset and the lateral offset of these fields relative to each other in the area of joints between the individual adjacent concrete fields and to absorb temperature-related changes in length almost without constraint.
- a variant with a radial bead arranged on the equator and a spherical cover with openings for the dowels slid on there is provided for use in crunching joints.
- the shell extends over the entire length of the anchor and has longitudinal slots in the central area, which is protected by the spherical cover, and is slightly curved in this area in order to be able to follow the movements of the concrete fields.
- Caps are attached to the ends of the dowels, which have recesses through which reinforcement rings can be inserted, which run parallel to the joint and thus hold the dowels in place.
- EP 0 633 356 A corresponding to DE G 931 01 29.5 U, discloses a joint dowel which consists of a base element made of round metal and a plastic casing, the Plastic envelope as a closed unit is longer in the axial direction and larger in diameter than the basic element and the plastic envelope has at least one crumple zone.
- This joint anchor is said to be suitable for expansion, cutting, movement or day joints, but the necessity to provide a crumple zone in the plastic envelope actually makes this anchor only suitable for room joints, since the crumple zone must be at least essentially outside of both concrete ceiling parts to perform their function.
- the invention aims to create such a joint dowel and achieves these goals in that the plastic casing consists of at least two parts which are at least essentially opposite each other in the middle of the longitudinal extension of the joint dowel and in this area from one in the circumferential direction to tension claimed plastic hose are surrounded, wherein the at least two parts of the plastic sleeve have protruding and recessed areas on its outer surface.
- the measures according to the invention ensure that each of the plastic casings of a dowel according to the invention is positively held by that of the two concrete fields in which it is located and that the movement of this concrete field reliably takes part.
- the plastic tube is preferably made of silicone material (also referred to as silicone, in particular as silicone rubber) and is able to endure extreme elongations, even if these are repeated often and often.
- the steel rod or a rod made of another metal or high-strength plastic - moves inside the plastic shell in the plastic shell and that it remains immobile in relation to the respective concrete field. This is a basic requirement for Maintaining the tightness of the overall system and thus preventing corrosion.
- the silicone material used with preference is a high polymer, cross-linked polysiloxane, optionally with inorganic fillers.
- a product is available from Rehau under the name RAU-SIK.
- the plastic casing consists of two parts of the same structure and the protruding or recessed surface parts are arranged along at least three, preferably four, possibly also more, ribs extending in the axial direction.
- these ribs end on the ⁇ side of the open casing ends at a distance from the casing ends, so that the plastic tube can be plugged onto a smooth cylindrical outer surface, the correct axial position according to a preferred embodiment of the plastic hose is marked and secured by an outwardly protruding circumferential shoulder.
- FIG. 1 shows a preferred embodiment of the joint anchor according to the invention in a side view, partly in section and an end view
- FIG. 2a shows a mounting plate m according to the invention
- FIG. 2b shows the mounting plate according to the invention in three sectional views.
- a joint dowel according to the invention designated 1 in its entirety, consists of two plastic sleeves 2, which at one end have a base 3 formed integrally with them and open at the other end.
- Ribs are not smooth on their outer surfaces, but have protruding areas 6 and recessed areas 7. These ribs 5 extend from the bottom 3 over the greater part of the length of the plastic casing 2, but end at a distance from the open end 8 of the plastic casing 2.
- this has a smooth cylindrical surface which m a predetermined distance from the free end 8 in a
- Ring bead or ring shoulder 9 passes over.
- the ribs 5 extend between this annular shoulder 9 and the base 3.
- the plastic hose 10 is preferably made of silicone or another plastic material with great elasticity and can therefore withstand very large changes in length when the joint is torn open (if it is not used in the area of a space joint) even over the small axial area that is then released. Silicone or other material to be used is also able to endure such changes in length and their reshaping almost as often as required; the material is durable in this regard.
- the actual metallic or high-strength plastic dowel 4 which, depending on the use, can still be protected against corrosion in accordance with the relevant standard.
- the actual metallic or high-strength plastic dowel 4 which, depending on the use, can still be protected against corrosion in accordance with the relevant standard.
- it fills the interior of the two plastic sleeves 2 m in axial length to the whole; in the case of crunching joints, it only receives its axial play via the shrinkage of the concrete during its drying.
- the number of ribs 5 can be changed, the bottom 3 of the plastic sleeves 2 can be glued or welded on, this bottom can be cup-shaped and then used as a Tube trained plastic sleeve are pushed, the connection can then be made by elastic deformation, by providing appropriate elastically bendable components (barb-like).
- surface texturing can also be provided instead of the ribs 5, but this is not preferred because of the complicated production.
- the annular shoulder 9 can be designed differently from the illustration or can be omitted at all, as a result of which the ends of the ribs 5 or other projecting elements of the plastic sleeve 2 take over the fixing and adjustment of the plastic tube 10; with suitable assembly tools, the arrangement of such adjustment aids can be dispensed with at all become.
- 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 anchor, 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 , in order to prevent the dowel in the still wet concrete, in particular during its compaction by virbration, sinks to the floor. This measure is particularly important for anchors that are laid individually while the concrete is still wet.
- the joint dowel 1 is preferably assembled as follows, as shown schematically in FIGS. 2a and 2b: the plastic hose 10 is pushed briefly over the plastic sleeves 2 and then the dowel 1 is placed on a board-like work station or a mounting plate 14 between two lateral ones Elevations 12, which converge, inserted (position I). It is then moved in a rolling manner in the direction in which the two lateral elevations 12 converge, a recess or groove 13 being provided in the area in which the plastic tube 10 is located by running onto the lateral elevations that converge obliquely 12, the two plastic sleeves are pushed 2 m into the middle and deform the plastic tube 10 like a bellows (position II).
- the groove 13 ends (tapering), so that pressure is exerted from below in the radial direction in the radial direction on the plastic hose 10, which continuously acts in a narrow area as the dowel rotates along the circumference due to this pressure , combined with the lateral pressure and the bellows-like deformation, the plastic hose is caused to jump suddenly over the plastic sleeves 2 and to resume its essentially circular-cylindrical shape.
