Definitions

  • the invention relates to a method and the associated means according to the preamble of claim 1.
  • a rail fastening of the type mentioned is known from DE-OS 2102306.
  • a formwork is created around the installation parts, ie usually around a ribbed plate, which serves to fasten the rail, and defines the horizontal extent of the elastic body.
  • the cavity thus created is then filled with elastomer through pouring openings in the fin plate. Elastomer is filled in through one opening, while the room is vented at a second opening.
  • This relatively simple method has the particular advantage that a connection that is completely adapted to the installation height and is also still tight can be created in one operation between the substrate and the rail.
  • the firm connection to the substrate is usually carried out by means of retaining bolts to be inserted within the region of the elastic body.
  • this formwork is created from wooden slats, which must be provided with a release agent, so that they can be dismantled again without great difficulty.
  • the result of this is that the formwork for each individual point of the rail fastening has to be assembled by hand in a time-consuming manner.
  • the formwork is packed with sand to prevent the leakage of elastomer at the remaining gaps. This is to keep the rework on the later visible rail fastenings as low as possible.
  • the object is achieved by a method according to the characterizing part of claim 1.
  • the foam sealing tape described in the subclaims can be easily installed and can remain in the installation site after the elastomer has polymerized. Both parts have a close connection. An impregnation protects the sealing tape from the weather and makes it durable over a long period of operation.
  • the surface of the elastic body or the rail fastening is also visually easy as a visible surface. Ease of work is also through. Prefabricated sealing elements can be used in a rectangular shape.
  • Fig. 1 a rail fastening with sealing
  • Fig. 2 shows a section through a seal
  • Fig. 3 shows a corner of a seal
  • Fig. 4 shows a horizontal section through an attachment point.
  • FIG. 1 A cross section through a rail fastening is shown in FIG.
  • a rail 1 is placed on a ribbed plate 2 for attachment by the usual means, i.e. it is securely fastened there with clamping means.
  • the connection must be secure so that the rail 1 cannot make any transverse movements with respect to the ground.
  • the ribbed plate 2 thus serves for later fastening of the rail 1 on a base 3 with screwed-on brackets or tensioning elements, which are not shown here, and must be leveled accordingly.
  • the ribbed plate 2 itself is anchored in the base 3 with anchor screws 4, in special cases it can also be "glued” only with a plastic.
  • the rib plate 2 is provided with four holes 5 in the area of its corners for fastening. At least two of these four holes 5 lying diagonally opposite one another are used to attach one anchor screw 4 each. The two remaining holes 5A, B can be used for filling or venting when filling the plastic.
  • a sealing tape 6 is in compressed form and is provided on one side with a self-adhesive coating 7. With their help, a border with the sealing tape 6 is glued to the edge of the rib plate 2 from below. This creates the cavity 8 required for the elastic bearing body 9 to be produced.
  • care must of course be taken to ensure a good seal at the corners of the ribbed plate 2.
  • the sealing tape 6 is intended for processing, ie. in the compressed state, have approximately the thickness of the sealing gap S formed during installation between the ribbed plate 2 and the base 3.
  • a plastic for example, can be introduced directly into the cavity 8.
  • a special press device with a cartridge of the plastic to be processed is attached to a filling opening 5A.
  • the air displaced when pressed into the cavity 8 can escape at a ventilation opening 5B. It takes a few hours for the plastic to polymerize completely.
  • the bearing body 9 is finished without further rework and connects the rib plate 2 and the base 3 without joints.
  • the outside of the bearing body 9 thus formed is formed by the outside of the sealing tape 6. Since the sealing tape 6 is equipped to withstand the weather and is optically suitable as a visible edge, it can remain directly at the installation site. The assembly of the rail 1 is thus already completed for an attachment point. By appropriately interlinking the assembly processes for a series of fastening points, loss of time due to the waiting times for the expansion of the foam of the sealing tape 6 can be avoided. Holes 5A, B are sometimes not available for introducing the plastic, because four anchor screws 4 are required for fixing to the base 3. Then, using the elasticity of the sealing tape 6, a feed HA and, on the opposite side, a vent 11B can also be inserted between the ribbed plate 2 and the sealing tape 6. This could be taken into account, for example, by inserting tubes when installing the seal. The complete filling of the cavity 8 is thus also achieved.
  • the sealing tape 6 shown in Figure 2 is equipped on one side with the self-adhesive coating 7 and is thus attached directly to the ribbed plate 2. If the installation space underneath the rail is large enough to allow the ribbed plate 2 with the sealing tape 6 to be inserted under the rail 1, this is possible prior to the installation on the rail, which would further simplify the process. Since the sealing tape 6 is compressed to approximately 30% of its full volume, it can also be relatively easily attached to the rib plate 2 pre-adjusted under the rail 1.
  • the two extreme states of the sealing tape 6 are denoted by ZI and Z2 and indicated by dashed lines. In the initial state ZI, the sealing tape 6 is thinner than the height of the sealing gap S.
  • the seal In this state, the seal is unloaded and will expand more or less quickly depending on the outside temperature. The expansion is limited by the system on the subsurface 3. If the foam could expand unhindered, the sealing tape 6 would reach a thickness corresponding to the final state Z2, which is a multiple of the height of the sealing gap S.
  • the base 3 will consist of a solid material such as steel or concrete, but still has unevenness.
  • the sealing tape 6 is now able to compensate for all unevenness due to its large final volume and yet to develop a sufficiently high sealing force on the counter surface of the substrate 3. It should be noted here that the initial thickness D of the sealing tape 6 is at least half the size of the Sealing gap S reached. Otherwise problems with the sealing can arise.
  • width B of the seal 6 which means that it is not significantly less than the final height.
  • the height of the sealing gap S should be.
  • a minimum value can be achieved for the width B of the sealing tape 6 in order to lose as little space as possible for the support on the elastic bearing body 9 and not to weaken its resilience.
  • the width B of the sealing tape 6 also only has an influence on its resistance to the pressure forces when filling the liquid plastic. These are defined by adjustable parameters, such as injection pressure and viscosity of the
  • FIG. 3 shows a sensible measure for processing the sealing tape 6 when processing from the roll before installation. So that the sealing tape 6 does not bulge too much at the corners when inserted under the ribbed plate 2, it should be cut out in a V-shaped manner in the corresponding area, with a sufficiently strong remaining wall remaining so that the sealing tape 6 does not lose too much stability . When bending at the corners of the ribbed plate, the foam can then be easily inserted without bulging.
  • FIG. 1 A further embodiment of the sealing tape 6 is shown in FIG.
  • the section through the bearing body 9 shows that the sealing tape 6 lying around it is designed in the manner of a window as a frame seal 10. It is thus directly prepared for final assembly. If the frame seal 10 is to be installed around preassembled anchor bolts 4, it can be easily separated with a knife cut. The manufacture of the seal is simplified again considerably when using such a prefabricated frame seal 10.
  • the production of the bearing bodies 9 can be designed continuously.
  • previously installed sealing tapes 6 expand and after a waiting time, for example. one hour at an outside temperature of approx. 18-20 degrees Celsius, the liquid plastic mass can already be filled.
  • a sealing material e.g. the product "illmod" from illbrück Bau-She, D-5090 Leverkusen can be used.
  • the data sheets available for this purpose have all the necessary information for processing, such as thickness and width of the seal, temperature for processing the foam, waiting times depending on the temperature, etc.
  • the expansion of the foam can also be supported by the use of warm air in unfavorable weather conditions.
  • a further embodiment is possible within the scope of the inventive concept of creating an easily installed and durable seal that remains at the installation site for the creation of elastic bearing bodies for the rail mounting.
  • the shape and attachment of the sealing tapes can be varied depending on the application.

Abstract

Un procédé permet de produire un renforcement élastique de rails en un matériau façonnable à l'état fluide, puis durcissable. Le renforcement peut être monté sur place. Avant la pose définitive du rail (1), la semelle nervurée (2) est premièrement suspendue et assujettie au rail aligné (1). Ensuite, les bords du lit de support (9) que l'on veut créer sont rendus étanches. Une bande d'étanchéité précomprimée (6) est pourvue d'un côté d'un revêtement auto-adhésif (7). On utilise cette bande d'étanchéité (6) pour coller un cadre sous les bords de la semelle (2), de façon à créer la cavité requise (8) pour le lit de support élastique (9) que l'on veut former. Après une période déterminée d'attente, le produit alvéolaire dont est constituée la bande d'étanchéité (6) se détend et est alors étroitement serré entre la semelle nervurée (2) et le sol (3). Une fois que la bande d'étanchéité (6) s'est suffisamment détendue, on peut introduire directement dans la cavité (8) une matière plastique, par exemple. L'air refoulé dans la cavité (8) pendant la compression peut s'échapper par un orifice d'aération (5B), par exemple.
