Definitions

  • the invention relates to a joint sealing profile made of elastic material for closing a joint between two structural parts, with an upper continuous central section, the surface of which forms a cover surface arranged in the region of the surface of the structural parts in the installed state, and with two side legs attached to the longitudinal ends of the central section , wherein the adjacent surfaces of the structural parts are designed to match the side surfaces of the profile legs.
  • the central section has a cross section in the form of a trapezoidal block with side surfaces converging from the surface thereof, the side legs formed on the block diverging in the direction of their free ends. It is provided that in an arrangement of this known joint sealing profile in a longitudinal joint between the building parts, the connection points of the two legs to the block are designed in the form of articulation points, and both the trapezoidal block and the legs of the profile can be movable relative to the adjacent surfaces of the building parts should. When installed, this joint sealing profile is only fixed by the fully embedded tabs and aligned by the legs supported on one side and the side surfaces of the block.
  • the trapezoidal block of the known profile is inclined, as a result of which the contact pressure between the side surface of the block and the adjacent surface of the lower structure and in this way also the sealing contact on both sides should be maintained .
  • the joints in the form of articulations of the legs to the block should allow the block good mobility, the lateral bitumen or concrete masses reaching to the side surfaces of the block and the legs forming a projecting edge in the region of the articulation points, which the retention of the The position of the articulation points in the predetermined area is guaranteed, even if a vertical offset occurs between the connected structural parts.
  • the thickness of the side legs is considerably less than that of the trapezoidal block, the massive design of which has to absorb the vertical loads of the central section.
  • joint sealing profiles for covering the joints between two adjacent parts of the building presupposes that such joint tapes can also perform the function of compensating for the relative movements between the building parts as easily as possible because the joint tapes are generally only integrated in the bridge insulation . Even if the main thing is to compensate for vertical offset movements of the building parts relative to one another, the joint tape must also absorb and compensate for horizontal movements of the building parts relative to one another as softly as possible.
  • the known joint sealing profile can only ensure the required compensation to a very limited extent when horizontal relative movements of the building parts occur, with the sealing contact closing especially when the building parts move horizontally apart (joint enlargement) Both side surfaces of the trapezoidal block and the adjacent concrete or bitumen covering are lost, a gap occurs between the side surface and the protective concrete and moisture can penetrate undesirably.
  • the thick design of the central section makes it relatively rigid, so that elastic expansion or compression when the structures are horizontally offset from one another can lead to the formation of waves on the surface of the block or to the above-mentioned signs of separation.
  • the object of the invention is to propose a joint sealing profile which, while largely avoiding the disadvantages shown, enables a deformation-less absorption of the relative displacement movements of the structural parts with respect to one another, in particular also the horizontal displacement movements, in which the stress load on the middle section covering the joint is reduced and in the event of detachments compared to the lateral protective concrete in the event of offset movements of the structural parts, they are completely eliminated or at least kept particularly low.
  • the central section is in the form of a relatively thin shroud which deflects under load formed and on each side leg a thickening is attached, on which an upper support surface is attached to abut a portion of the underside of the shroud, this support surface is preferably arranged away from the underside of the shroud at a distance of a small gap such that the gap when extending the cover tape is lifted under load.
  • the middle section As a relatively thin shroud compared to the thick, block-shaped middle section of the known joint tape, it is first achieved that, when a vertical load occurs, the middle section no longer has to take over the transmission of the occurring vertical forces into the side legs, but rather give in downwards can and thereby enables the support on the support surfaces.
  • the introduction of the vertical forces directly from above via the support surfaces into the side legs also causes the side legs to be loaded even in the direction of good contact with the side concrete and thus completely prevents the occurrence of detachments in most load cases.
  • the lower leg sections are therefore and also due to the thickening in any case firmly against the side concrete, i.e. Relative movements to the protective concrete do not occur (in contrast to the known profile). If, in the unloaded state of the profile, the support surfaces are arranged at a distance of a small gap from the underside of the cover band, the cover band springs out under load until the gap completely disappears, as a result of which the cover band comes into contact with the support surfaces and then the vertical load that occurs can be introduced into the corresponding thickenings of the side legs via these support surfaces.
  • the thickenings can be provided with any suitable shape in order to derive the forces occurring as cheaply as possible.
  • elastic materials in particular elastic plastics (elastomers) or also natural rubber (NR) can be used as the elastic material for the joint sealing profile according to the invention.
  • the joint tape according to the invention can react relatively softly because the expansion of the central section which occurs at the same time is easily possible as a result of its design as a thin cover tape.
  • the middle section above, bridging the joint is almost kept free from the absorption of vertical loads that occur, by separating functions for absorbing vertical loads on the one hand by thickening the lateral legs arranged below the central section and absorbing the compensating forces, in particular in the case of a gap enlargement by means of an elastic one Elongation of the relatively thin shroud on the other hand can be done by separate sections of the joint sealing profile.
  • This is a fundamental advantage if only because each of the force-absorbing profile parts can be specially adapted to its special function and can be designed and shaped independently of the function of the other force-absorbing parts.
  • an improved absorption of forces and thus a more targeted design of the entire sealing profile for the forces occurring during use can be achieved, whereby the risk of undesired permanent deformations can also be excluded or at least minimized.
  • each side leg consists of two leg sections, the lower of which has the thickening and the upper, on the other hand, are significantly thinner, the shroud connecting the two thinner leg sections, and that the lower leg section on one side protrudes into the height extension region of the upper leg section, which is substantially thicker than the upper leg section and has the support surface at its upper end.
  • each side leg also ensures that the middle section does not run into a rigid and relatively immovable holder as soon as it opens into each side leg, but rather that the upper part of each side leg also makes a contribution for a soft resilience of the upper shroud in its longitudinal extent and only the lower section of each side leg, on which the thickening with the support surface is arranged to absorb the horizontal forces, represents a correspondingly more rigid, force-transmitting component.
  • a very particularly preferred embodiment in the joint sealing profile according to the invention is that on the top of each projection one in the direction of the profile center line downward inclined connecting surface is formed towards the supporting surface and, again preferably, has a longitudinal extension; which corresponds essentially to the longitudinal extent of the support surface.
  • a suitable angle of inclination can be selected for the slope.
  • an angle between 10 ° and 30 ° to the level of the support surface is very particularly preferably inclined downwards.
  • each inclined connecting surface is particularly preferably arranged separately from the associated supporting surface via a wedge-shaped incision or a notch, which has the advantage that even a certain change in the angle between the two surfaces is then possible, as a result of the notch up to one To some extent, a relative pivoting of both surfaces is still possible.
  • the support surfaces can also be divided into a plurality of partial support surfaces by such incisions running in the longitudinal direction of the joint sealing profile, as a result of which a better adaptation of the total support surface formed in this way to an oddly running counter surface of the cover tape is possible.
  • the thickness of the shroud is preferably chosen to be at least one and at most twice the thickness of the upper leg sections, again, preferably, being substantially constant along the extent of the shroud. In this way, an excellent functionality can be obtained with a simple shape.
  • the joint sealing profile according to the invention is very particularly preferably provided with a profile cross section which is symmetrical with respect to its profile center line, as a result of which particularly favorable absorption of occurring loads is ensured.
  • the size of the support surfaces is advantageously chosen so that - seen in profile cross-section - the total area of all support surfaces supporting the shroud from below is 40% to 60%, but preferably about half the area of the underside of the shroud.
  • angled tabs are also formed on the free end of the side legs in the direction of the main plane of the building parts, along which the integration into the insulation on the side building parts can then take place, which in connection with the thickened side leg section results in a particularly rigid design of the Transition from the side leg end to the tab results and thereby the immovable position of the partial section formed from the thickened side leg section and tab is secured relative to the protective concrete, ie Any detachment of the side surfaces there from the adjacent protective concrete layer and any relative movement between these parts is completely avoided.
  • the upwardly projecting projection of each lower leg section is preferably designed to rise obliquely in the direction of the profile center line, thereby ensuring a favorable dissipation of the forces absorbed into the thickened lateral leg sections.
  • the protrusion is preferably made with an increasing thickness.
  • the upwardly projecting projection is very particularly preferably offset at a lateral distance from the upper leg section, so that the most suitable distribution of the support surfaces below the upper cover band can be achieved by a suitable choice of distance.
  • Another preferred embodiment of the joint sealing profile according to the invention also consists in the fact that the lower leg section has a thickness that decreases towards its free end. For special applications, however, it may be equally desirable that the thickening of the same be carried out substantially constant over the length of the lower side section.
  • a cross-sectional reduction in the form of a profile indentation which is directed inward from the outside of the side leg and is preferably rounded, is provided in order to facilitate the pivoting of the respective upper side leg section (and thus also of the cover tape attached to this) relative to the massive, immovable, thick, lower leg section.
  • a friction-reducing coating e.g. Polytetrafluoroethylene (PTFE).
  • the cross section of the joint sealing tapes shown in all figures has an upper middle section 1 in the form of a cover tape, on the two lateral ends of which legs 2, 3 are attached.
  • the side legs 2 and 3 each consist of two leg sections 4, 6 and 5, 7.
  • the upper leg sections 4, 5 are made relatively thin, while the lower leg sections 6, 7 have a massive thickening, but different in shape can be trained.
  • the thickened leg sections 6, 7 each have a projection 8 and 9, which protrudes upwards obliquely towards the profile center line MM (FIG. 1), this projection, as can be seen well from the figures protrudes up into the area over which the lateral upper leg section 4 or 5 extends (in height).
  • a support surface 12, 13 is formed at the top of each projection 8, 9 at a small distance S from the underside 1 'of the shroud 1, the alignment of which (in the unloaded state of the joint tape) is essentially parallel to the alignment of the underside 1' of the shroud 1 runs.
  • the start of the support surface 12, 13 is offset laterally by a distance A laterally from the corresponding upper section 4, 5 of the relevant side leg 2, 3, and each support surface 12, 13 extends over a longitudinal extension L. , which in the embodiments shown in FIGS. 1, 2 and 5 each corresponds to about a quarter of the total extent of the underside of the shroud 1 '.
  • a cross-sectional constriction is provided, in the form of one from the side surface of the relevant side leg 2, 3 inward, circular segment-shaped bulge 10, as shown in FIGS. 1, 2 and 5.
  • This cross-sectional constriction which in its lower area can also run a little into the area of the lower leg section 6, 7, enables easier pivoting of the respective upper leg section 4, 5 relative to the lower, rigid, immovable thickened leg section 6, 7. which contributes to an improved mobility of the upper shroud 1 and the two upper leg sections 4 and 5 which are directly connected to it, relative to the rigid blocks 6 and 7 arranged underneath.
  • the thickness d i , d 2 of the upper leg sections 4 and 5 is approximately as large as the thickness D of the upper shroud 1 in the illustration according to FIGS. 1 and 2.
  • FIG. 2 shows, compared to the profile shape from FIG. 1, the change that the profile thickening below the respective support surface 12, 13 remains essentially the same over the height of the respective lower thickened leg section 6, 7, while in the embodiment according to FIG 1 there is a cross-sectional shape which tapers over the height of the lower leg section 6, 7 in each case in the direction of its free end.
  • each support surface 12, 13 is divided by a notch-shaped incision 26 'into two partial support surfaces 12', 12 'and 13', 13 ', which can be adjusted at a small angle to one another when corresponding loads occur, as a result of which better adaptability to the Shape of the counter surface l 'is possible.
  • the joint sealing profile shown in FIG. 1 is shown in FIG. 5 in the installed position between two bridge structures, between which a joint of width W is to be bridged.
  • the tabs 11 which are angled laterally at the free ends of the lower leg sections in the direction of the main plane of the building parts, are placed on the top of the building parts 20, 21 with the interposition of sealing strips 22, 23 and then laterally with a concrete - or bitumen layer 18, 19, in which reinforcements 24, 25 are attached, supported laterally.
  • the joint sealing profile which is shown in FIGS. 3 and 4, differs from the joint sealing profile from FIG. 1 in that the support surfaces 12, 13 no longer have a continuously common orientation, but only in their first, the relevant upper leg section 4, 5 facing initial part along a length L to the underside 1 'of the upper shroud 1 are aligned, which is separated by a deep and narrow notch groove 26, a connection surface 14 or inclined at an angle downwards towards the center of the profile cross section 15 a length L '(which corresponds approximately to the length L of the support surface 12 or 13).
  • This ensures that in the installed state of the profile seal, as shown in Fig. 4, when a vertical offset h occurs between the two structural parts, the support surfaces 12, 14 attached to the higher structural part emit a particularly well-adapted support on the underside of the shroud 1.
  • the profile seals themselves are made from a suitable elastomeric plastic, but in certain applications vulcanized natural rubber can also be used (e.g. for use in extremely cold temperatures).
