Definitions
- the invention relates to a device for bridging expansion joints, in particular in bridges, roadway parts or the like, according to the preamble of patent claim 1.
- German patent 28 08 386 A device of this type is known from German patent 28 08 386. If this known device, which has a non-accessible sealing profile strip and therefore can only be used for very narrow joints, a greater tensile stress or a one-sided vertical thrust occurs, a gap can open between the joint edge profile and the sealing tape received therein, in the moisture and dirt can penetrate. In the long run, this leads to damage to the sealing tape, and the joint edge profile can also be affected by corrosion.
- German patent 31 31 804 which has a sealable strip that can be driven over, the entry of moisture and dirt into the cavity of the joint edge is not avoided with certainty.
- the invention has for its object to improve a device for bridging expansion joints of the type mentioned so that the penetration of dirt and moisture into the cavity of the joint edge is avoided with certainty, even with considerable tensile stress and one-sided vertical thrust, so that the service life this device is significantly extended.
- the joint bridging device not only is the thickening formed on both sides of the sealing tape wedged in the cavity of the joint edge so that the sealing tape is securely held in the joint edges, but a pretension is generated in the edge area of the cavity in the sealing tape applied there .
- a projecting nose which is formed on the thickening of the sealing tape, is compressed in the installed position, which results in the contact pressure which prevents the sealing tape from coming loose from the inner wall of the cavity in the region of the edge sections.
- the size of the pretension can be determined by choosing a suitable inclination of the nose to be compressed so that the tensile forces acting in the direction of the joint and the vertical forces acting perpendicularly to it in practice are smaller than the pretension of the sealing tape arranged in the cavity.
- the projecting nose is expediently formed in one area; which abuts an edge portion of the cavity. This measure ensures that the desired contact pressure exists on both edge sections of the cavity, so that any penetration of dirt and moisture into the cavity is reliably avoided
- the joint edge profile forming the respective cavity has a trough-shaped recess with an essentially horizontal and an essentially vertical edge section.
- the horizontal edge section extends approximately halfway up the recess in the direction of the joint, while the vertical edge section runs on the side facing away from the joint to the upper edge of the roadway. The thickening of the sealing tape pressed into the cavity of such a joint edge profile is thus under tension on the one hand against the vertical edge section of the cavity, while on the other hand it lies snugly on the horizontal edge section, so that there is always a supporting bearing for the sealing tape
- the vertical edge section can be an inwardly flanged edge of the joint edge profile, the lower horizontal edge of which is gripped by the supporting surface of the thickening. Since the thickening of the sealing tape is pressed obliquely from top to bottom into the cavity, this arrangement of the inner surface of the cavity adjacent to the supporting surface ensures a reliable wedging of the sealing tape while the buttoning of the thickening into the cavity is simple to carry out .
- the projecting nose is formed in the area of the thickening which, in the installed position, bears against the vertical edge section of the joint edge profile.
- the compressed nose in the installed position prevents the ingress of dirt and moisture even in this particularly vulnerable area if when the joints are opened, tensile forces occur in the sealing tape.
- a contact pressure of the thickening is generated against the horizontal edge section of the joint edge profile, so that when the joints are narrowed, bulging of the thickening and loosening of the sealing tape from the horizontal edge section is prevented.
- the support surface of the thickening is inclined in the direction pointing away from the joint, i.e.
- the edge of the joint edge profile is inclined correspondingly to the supporting surface of the thickening, so that in the installed position of the thickening a contact pressure is also generated in the area of the supporting surface, which ensures a firm hold and a secure seal in this area.
- the thickening advantageously has a cavity in the area of the support surface, which is either formed by a hollow chamber or a through hole and enables the projection adjacent to the support surface to move in the direction of this cavity when the sealing tape is inserted into the joint edge profile.
- the width of the thickening expediently has an excess in relation to the entry cross section of the joint edge profile, so that the sealing tape with the thickening and the pretension is held in the joint edge profile.
- the projecting nose expediently runs in the relaxed state essentially at an acute angle to the corresponding wall section. This allows a largely uniform distribution of the pretension to be achieved.
- the thickening in the installed position has a substantially horizontal section which rests on the horizontal edge section of the joint edge profile. This creates a large-area support for the sealing tape in this area, which is always load-bearing due to the prestressing the sealing tape of the traffic load acting for a long time, so that its service life is considerably extended.
- the top of the thickening is flush with the top of the road in the installed position.
- the sealing tape is designed as a hollow profile in the region of the joint.
- the hollow profile is formed by diamond-shaped ribs.
- the hollow profile has an overall V-shape on its underside.
- the hollow profile On its top side, the hollow profile has advantageous V-shaped cavities between the diamond-shaped ribs whose upper edges are aligned with the built-in thickening and the upper edge of the road.
- the diagonally running ribs stabilize the hollow profile of the sealing tape located between the joint edges in such a way that a completely flat design of the surface of the sealing tape adjacent to the traffic surface is ensured in every joint position, that is to say even when the joint is narrow.
- the thickening 2 has a flat upper side 3 which, when the sealing tape 1 is in the installed state, runs flush with the top edge 4 of the road (FIGS. 2 and 4), and a lower contact surface 5 which forms a support for the thickening.
- the thickening 2 is further provided with a nose 6 which is compressed in the installed state of the sealing tape, so that it then runs essentially vertically or horizontally.
- the thickening 2 merges at its lower end section into a web 8 which ends in a bead 9.
- the thickening 2 has about halfway up the left edge in FIG. 1 a projection 7b adjoining the support surface 7, which protrudes from the inside outwards and in the installed state (FIG. 4) against a lower edge 18 (FIG. 2) In this area there is also a cavity 7a, which enables the projection 7b to be pressed inwards in the direction of the cavity when the thickening 2 is inserted into the joint edge profile 12 (see FIG. 3).
- Fig. 2 shows a cross-section with adjoining joints in the joint 10 concrete base 11.
- the joint edge profile 12 is embedded in a plastic concrete bed 13 to which the asphalt road 1 4 is connected.
- the joint edge profiles 12 have an essentially trough-shaped cavity 15.
- a horizontal edge section 16 extends approximately halfway up the joint edge profile 12 in the direction of the joint 10.
- a vertical edge section 17 is formed at the edge of the joint edge profile 12 and extends to the top edge 4 of the roadway.
- Fig. 3 it is shown how the sealing tape 1 with the thickening 2 is inserted into the joint edge profile 12.
- the projection 7b adjoining the support surface 7 is pressed inward in the direction of the cavity 7a, so that the thickening 2 can be introduced into the trough-shaped cavity 15 through the narrowed cross section 22.
- Fig. 4 shows the fully installed sealing tape
- the side thickenings 2 are aligned with their tops with the top edge 4 of the roadway.
- the nose 6 is compressed and bears against the vertical edge portion 1.
- the projection 7b bears against the edge 18, the projection 7b forming a supporting surface of the thickening 2 in the cavity.
- the web 8 with the bead 9 is bent toward the joint, so that the bead 9 abuts slightly above the support surface 7a on an inner wall section of the joint edge profile 12 and the thickening 2, and the thickening 2 is wedged in the cavity 1 5.
- the horizontal bearing surface 5 the thickening 2 lies under prestress on the horizontal edge section 16 of the joint edge profile 12, so that the thickening has a total of 3 bearing surfaces 5, 6 and 7, which are pressed against the inner wall of the cavity 15. This design ensures a secure, spattless fit of the sealing tape in the joint edge profile.
- the sealing tape 1 is designed as a hollow profile 19.
- This hollow profile consists of diamond-shaped ribs 20, the individual diamonds on the top of the hollow profile 19 being aligned with the built-in thickening 2 and the top edge 4 of the roadway.
- V-shaped cavities 2 1 are located on the top of the hollow profile between the individual rhombuses.
- the hollow profile 19 is V-shaped overall
- the diagonally running ribs 20 enable the vertical loads to be removed properly towards the joint edge. Due to its special design, the hollow profile is stabilized in such a way that its surface is perfectly aligned with the top of the road even when the joint is narrow
