Definitions

  • the invention relates to an elastomeric expansion profile for sealing expansion joints on the building side, the fold-bridging fold part of which has on opposite sides an edge part running in the longitudinal direction of the joint, which comprises a web with fastening elements on the free web edge, which in the installed position in grooves open towards the joint of the joint edges intervention.
  • a known elastomeric joint seal (US Pat. No. 4,007,994) has projecting strips on both side edges pointing towards the respective joint edge, which have an arrow profile in cross section.
  • the projecting ledges are pressed with their widened arrowheads into corresponding grooves in the joint edges, so that the arrow wings in the installed position prevent these grooves from widening from the inside. Pressing in the projecting ledges is difficult because of the high deformation forces; it cannot be carried out without tools.
  • the material must on the one hand allow a high elastic deformation, on the other hand it must be sufficiently dimensionally stable to be able to maintain the required strength of the connection.
  • a known sealing profile (German Offenlegungsschrift 2 808 386) has thickenings of the edge parts, which engage behind support surfaces from inwardly widened grooves of the joint edges. Because of the limited deformability of the edge parts when buttoning into the grooves of the joint edges, the form-fit that can be achieved and thus the strength of the connection are limited. Material fatigue that occurs over time can gradually loosen the connection.
  • the present invention has for its object to provide an expansion profile of the type mentioned for the sealing end of an expansion joint, which can be easily buttoned into corresponding grooves without additional fasteners, ensures a secure locking and is easy to manufacture.
  • This object is achieved in that at least on one side of the web adjacent to its end connected to the folding part, a projecting rib and on its free edge a movable bar pointing towards the rib, which includes an acute angle with the web, the thickness of the Web in the area of its rib at least the width of the groove in the joint edge and the thickness of the bar corresponds approximately to the height of the ribs, such that the bar can be inserted into the groove with the bar placed behind the rib, the bar in the end position of the bar against a support surface in one Widening of the groove cavity is reboundable.
  • edge part of an elastomeric expansion profile is that at least one side of the edge part is provided with a movable latch which springs out against the supporting surface and a thickening in the form of a rib closing the groove opening.
  • a particularly advantageous embodiment is that ribs and bolts are provided on both sides of the web, and that the ribs are wedge-shaped in accordance with the formation of the groove in the joint edge with increasing height toward the joint.
  • the buttoning takes place by flexible bending deformation in the joint between the horizontal web and the closed or ; molded latch.
  • the spring force of the bending deformation can be increased by inserting strips of sheet metal, plastic or fabric in the area of the horizontal web and the transom. Such a measure is particularly advantageous when using soft elastomers.
  • a supporting or cable reinforcement can also be provided, which makes it possible to unfasten it if necessary.
  • Unbuttoning is also only possible after overcoming the stiff pressure deformation of the bolt.
  • the resilient bolt creates a secure positive connection between the edge part of the expansion profile and the joint edge.
  • the edge profile When the edge profile is designed on one side, the rib and ledger expediently point downward in the installed position, so that the expansion profile can be fitted just below the road surface.
  • the joint gap above the expansion profile can therefore be kept flat and thus easily cleaned of dirt.
  • the web of the edge profile can be fastened in any installation position, that is to say vertically, horizontally or in any inclined position, that is to say in accordance with the respective arrangement of the grooves in the joint edges.
  • Fig. 1 shows a cross section through the Behnprofil with the folding part 1 located in the area of the joint and bridging the joint and laterally adjoining edge parts 2.
  • Each edge part has a horizontal web 3 and at the free end an angled latch 4 and further inside, on the Side of the latch, a rib 5.
  • the thickness of the latch 4 corresponds approximately to the height of the rib 5.
  • the edge parts 2, as shown in the example of the left edge part in Fig. 2 can be folded so that the latch 4 slips behind the rib 5, so that the edge part of the expansion joint easily into the Groove 6 of the joint edge 7 can be inserted.
  • the opening of the groove 6 corresponds approximately to the sum of the thickness of the web 3 and the height of the rib 5.
  • the overall dimension of the groove can also exceed the height of the groove slightly, which is easily possible in the context of the elastomeric deformation. This results in a particularly tight connection of the edge part on the joint edge.
  • Fig. 3 shows the completely buttoned joint edge, the rib 5 for the tight connection, the bolt 4 is responsible for establishing a positive connection.
  • the bolt 4 springs out in the direction of its unloaded shape according to FIG. 1 and lies with its end face against a supporting surface 8 of the groove cavity widened towards the inside.
  • a nose 9 delimiting the opening of the groove 6 is formed on the joint edge.
  • the nose 9 and correspondingly the rib 5 of the edge part of the expansion profile are formed obliquely with an enlargement of the opening of the groove 6 towards the inside. In this way, the effect of the bolt 4th reinforced.
  • the edge part in the area of the web 3 and the bolt 4 has a reinforcement insert 10, which can consist of strips of sheet metal, plastic or fabric.
  • strand-like reinforcements 11 are e.g. provided as wire or rope reinforcement to make it easier to unfasten the expansion profile.
  • the edge profile 2 has, in relation to the rib 5, a bead 12 which is continuous in the longitudinal direction and serves to improve the anchoring.
  • the angle which the bolt encloses with the web 3 in the fully installed position is somewhat smaller than the starting angle shown in FIG. 1, so that the bolt position remains elastically secured.
  • Fig. 8 shows the formation of an expansion profile with a double execution of the edge parts, that is, each edge part has two bars 4 on each side of the web 3 and two ribs 5, also on each side of the web 3. Accordingly, the inner cavity of the groove is with the widening for the support surfaces 8 formed symmetrically upwards and downwards.
  • the groove 6 is delimited in the opening area by parallel walls.
  • the walls of the groove 6 open towards the joint. In this way, a tensile pretension can be applied to the web part 3 between the ribs 5 and the bolt 4 during installation. The result is a particularly secure and tight link.
