Definitions

  • the invention relates to a joint tape for structural joints in tunnel construction, which is welded to the outer seal in the joint area of two adjacent tunnel sections to be created in concrete, in particular with inwardly projecting webs and a tubular expansion part.
  • tunnel construction is concreted in sections. Two methods are used: either the tunnel sections are concreted in a row in succession or a section is left between two sections, so that the first, third, fifth, etc. tunnel section is first made of concrete before the second, fourth , sixth etc. tunnel section is concreted.
  • the external seal at the eruption is laid continuously through the tunnel before the concreting work begins. At least the work on the external sealing precedes the concreting work.
  • joint tapes are several 100 mm wide and are welded to the external seal in the joint area before the concrete work is carried out. The welding takes place with the release of an expansion part of the joint tape. As a result, this results in two weld seams running parallel to the circumference and parallel to the joint between the joint tape and the external seal. Since the seal covers the entire tunnel cross-section, especially when the water is pressing, the joint tape then runs in a ring on the inside of the outer seal. The two weld seams mentioned in turn then form two parallel weld seam rings.
  • the joint tape thus reinforces and protects the area of the seal on the joint between two adjacent tunnel sections.
  • the welded joint tape is also provided on the inside with webs that are concreted in and on the one hand hold the joint tape in the concrete and on the other hand bring about an additional seal (partitioning) if the external seal is damaged in an unforeseen manner.
  • each tunnel section is also created section by section.
  • the concrete lining is poured in the area of the tunnel floor, then on the tunnel sides, before the concrete is poured in the ridge area in a final concreting step.
  • the formation of cavities is preferably due to trapped air or insufficient filling of the firebox with concrete. Added to this is the shrinkage of the concrete. That is why a lot accumulates in the ridge area light water, which then finds its way into the tunnel via the joint in the event of unforeseen damage to the external seal.
  • the object of the invention is to eliminate this danger. According to the invention, this is achieved by a leg on the joint tape provided in the ridge area and projecting downward.
  • the vertical leg lies exactly in the joint and can be attached to the formwork created for concreting when concreting.
  • the vertical leg has a length of at least 100 mm and is otherwise only limited by the thickness of the concrete lining.
  • the vertical leg is preferably provided on one side with webs which are concreted in and thus give sufficient support for the leg in the concrete.
  • the joint tape is provided with two legs which protrude downwards into the joint.
  • the contact surface of both legs is smooth, while the opposite sides are provided with bars for concreting in.
  • the two legs projecting downward in the joint tape production have an angle to the joint tape that is less than 90 degrees.
  • the angle is preferably approximately 60 degrees.
  • Both legs projecting downward then also enclose an angle of approximately 60 degrees between them.
  • Gluing and stapling is preferably carried out at the lower edge of the legs projecting downwards.
  • the joint tape has a tubular expansion part between the downwardly projecting legs and the remaining joint tape part.
  • Such tubular expansion parts are already provided together in the older proposal, and tubular expansion parts for joint tapes in tunnel construction are also common per se, provided that no downwardly projecting leg is provided, and such expansion parts can be provided with a predetermined crack location according to an older proposal.
  • the tubular expansion part tears open in the longitudinal direction of the hose in the event of excessive tensile load.
  • the predetermined crack location is always provided in the continuous belt level.
  • the tubular expansion part in the known joint tapes, before being torn open is also subjected to a very high degree of stretching stress in the part which is not intended to be torn open. After the cracking, the existing tensile forces remain and the tensile forces act solely on the material that is still present.
  • the tubular expansion part in the area of contact with the tunnel sections is provided with flow slopes.
  • Such an incline which can also be designed in the form of a rounding, prevents the expansion part from getting caught on concrete edges.
  • the open cross-section of the tubular expansion part is reduced by 10 to 40% by pressing in. The indentation can be effected very easily with the help of the legs projecting downwards and secured by striking the formwork. After the first definition of a leg on the formwork, the degree of indentation is also largely determined.
  • the advantageous flow movement while lifting off the concrete in the area of the tubular expansion part is also supported by a pretreated surface of the expansion part.
  • a pretreated surface of the expansion part for this purpose, an agent preventing the adhesion of the tubular expansion part to the concrete can be applied to the surface of the tubular expansion part be applied.
  • a plastic with little or negligible adhesive power for the tubular expansion part it is also possible to use a plastic with little or negligible adhesive power for the tubular expansion part.
  • an additional coating of the tubular expansion part with a non-stick plastic or substitute is also possible.
  • the breaking point is at the o. B. advantageous embodiments of the invention at the outer location of the tubular expansion part. I.e. the tubular expansion part tears open on the outside with excessive load. This allows the expansion part to yield further without losing its sealing effect.
  • the predetermined tear point is realized in that the material thickness of the tubular expansion part in the continuous band plane is less than in the remaining area of the tubular expansion part and the lateral joint band parts.
  • the joint tape profile according to the invention is produced by extrusion, this is achieved by appropriate arrangement of the mandrel forming the interior of the tubular expansion part. I.e. the mandrel is arranged accordingly close to the boundary surface of the tool.
  • the two downwardly projecting legs are at a distance from one another at their leg ends connected to the expansion part.
  • the arrangement at a distance ensures that a different setting of the tunnel sections does not lead to tearing off the legs and / or the webs provided on the legs.
  • the distance is preferably chosen so that the leg ends are arranged on the expansion part sides.
  • the legs projecting downwards can be fed towards one another around the expansion part.
  • the joint tape 1 has on both sides of the expansion channel 2 on the inside three webs 3 arranged at the same distance from one another.
  • the webs 3 are 4 to 5 cm long and ribbed.
  • the joint tape 1 is also provided with a vertical leg 4.
  • the leg 4 has a length of at least 10 cm to the joint tape 1 and also has webs 5 on one side.
  • FIG. 2 shows, in a tunnel situation (not shown), the shotcrete layer 10 lying at the rock eruption, a plastic seal 11 with an outside fleece 12 lying on the inside of the shotcrete layer.
  • the plastic seal 11 consists of a bitumen mixture containing ethylene copolymer.
  • the plastic seal 11 is composed of individual webs welded together. The weld seams are not shown.
  • FIG. 2 shows a ridge area with two abutting tunnel sections 15 and 16. There is a joint 17 at the joint. In relation to the tunnel sections 15 and 16, the plastic seal 11 is on the outside.
  • joint tape 1 is welded to the plastic seal 11.
  • the associated weld seams 20 are located at each free end of the joint tape leg that can be seen in cross section.
  • the above arrangement was achieved as follows: first the shotcrete 10 was applied to the rock eruption, then the plastic seal 11 with the fleece 12. The plastic seal 11 was secured against falling during its installation by means of holders in the shotcrete.
  • the brackets consist, for example, of inlaid or hammered nails or the like, which are provided with a plastic cover for sealing. The plastic cover is then welded to the plastic seal. This creates a point-like fastening of the plastic seal 11, preferably in the ridge area.
  • the attachment optionally has a predetermined breaking point, so that at certain tensile forces which occur in the seal 11, tearing off the cover or detaching the sealing membrane from the cover is ensured without at the same time causing damage to the seal.
  • the joint tape 1 has been welded to the plastic seal 11 in the joint area before the tunnel sections 15 and 16 are cast. Subsequently, the tunnel section 15 was first created, the vertical leg 4 of the joint tape 1 being attached to the ridge formwork for the tunnel section 15 in its lower region (nail tab) 18.
  • the vertical leg 4 extends in the ridge area over an angle of approximately 90 on either side of the vertical through the middle of the tunnel.
  • the vertical leg seals the joint 17 from water which, in the event of an unforeseen violation of the plastic seal 11 in the ridge area, flows through cavities formed there to the joint 17.
  • FIG. 3 shows a joint tape profile 101 according to the invention with a tubular expansion part 102, side legs 103 and 104 and legs 105 and 106 which point downward at 60 degrees.
  • the legs 105 and 106 abut one another on the tubular expansion part 102, and they likewise close an angle between them of 60 degrees.
  • the legs 103 and 104 together with the tubular expansion part form a joint tape surface which is smooth towards the top. This area is the contact area with the external seal in the tunnel. The welding takes place there.
  • the legs 103 and 104 are provided with webs 107 at the bottom (towards the tunnel interior).
  • the legs 105 and 106 projecting downward have webs 108 toward the legs 103 and 104, respectively.
  • the tubular expansion part has a tubular cross section 109 in the drawn state of manufacture.
  • the dimensions of the exemplary embodiment according to FIG. 3 are 30 cm joint width, 4 cm web height for the webs 107 and 108, at least 10 cm leg length for the legs 105 and 106, 4 cm diameter for the open hose cross section 109. Otherwise, a material thickness of 8 mm intended for legs and bars.
  • the tubular expansion part 102 is formed in the side area at 110 and 111 such that the tangent in each point of the side areas 110 and 111 meets the associated legs 103 and 104 at an angle of less than 80 degrees. This creates an advantageous flow slope in the side areas 110 and 111.
  • the welding can be carried out in such a way that two conventional joint tapes are angled without an expansion part until the two ends of legs 104 and 106 form one joint tape and legs 103 and 105 form the two ends of the other joint tape. After that, the two joint tapes are welded at the point of contact of the two legs 105 and 106.
  • the connection between the legs 103 and 104 is realized by inserting and welding a strip of material of smaller thickness. It is not necessary for the tubular expansion part to have the identical cross section according to FIG. 3.
  • FIG. 5 shows a detail of an expansion part 120 of a joint tape according to the invention which is produced by welding several joint tapes.
  • the expansion part 120 here has a triangular or trapezoidal shape, the material parts designated by 121 and 122 of two conventional joint tapes being provided by an internal extrusion seam 123 and optionally by one outer extrusion seam 150 shown in dash-dot lines are connected to one another.
  • the top of the joint tape is closed by a web 124 which is welded to the two conventional joint tapes forming the joint tape according to the invention with weld seams 125 and 126.
  • the legs 105 and 106 When producing a joint tape according to the invention from conventional joint tapes to be welded to one another, the legs 105 and 106 can be brought into the installation position shown in FIG. 4 from the outset. In this position, the legs 105 and 106 are perpendicular to the legs 103 and 104.
  • the downwardly projecting leg which is intended to be attached has been pushed upward by hand by approximately 3 cm below the deformation of the tubular expansion part 102 shown.
  • material of the tubular expansion part is available to a particular extent, which flows in the direction of the acting tensile force.
  • the tubular expansion part 102 can also stand out from the concrete sections 132 and 133 at 134 and 135, respectively. This process is facilitated by a appropriate surface treatment of the plastic, e.g. B. greasing in the area of the tubular expansion part 102. However, this can also be effected by a plastic film which is concrete-repellent and is laminated onto the tubular expansion part.
  • An embodiment according to FIG. 6 is particularly suitable for lamination. The lamination is then carried out on the conventional joint tapes which form the starting material in the region which forms the expansion part 120 after the welding of these joint tapes.
  • FIG. 5 shows a schematic illustration of a joint tape 140 with a leg 141 projecting downwards, which has two webs 142 and 143.
  • FIG. 3 shows the joint tape 140 in an installation situation without shotcrete and the associated tunnel sections.
  • the joint tape is provided at the ends of the legs 141 with further webs 144 and 145 which run parallel to the ends of the leg 141.
  • the webs 144 and 145 seal off the space between the webs 142 and 143 or the web 143 and the joint tape part running in the circumferential direction, so that inflowing water cannot flow into the joint in the circumferential direction of the leg 141.
  • FIG. 5 shows a joint tape with a leg 141 limited to the ridge area.
  • a joint tape according to FIG. 6 it can be advantageous to provide circumferential legs. Ie legs are provided over the entire circumference of the tunnel, which protrude inwards.
  • FIG. 7 shows a schematic cross-sectional representation of a joint tape in a ridge installation position with horizontally extending legs 201 and 202.
  • Each leg 201, 202 has webs 203 and 204 on the underside with which it is concreted into the associated tunnel sections.
  • a U-shaped expansion part 205 is located in the middle between the legs 201 and 202. This prevents concrete from penetrating the open cross-section of the U-profile.
  • the sides or vertical legs of the U-profile continue in legs 207 and 208 which project downwards and have webs 209 on the sides facing away from one another.
  • the leg 207 is concreted with its webs in the same tunnel section in which the webs 204 of the leg 201 are concreted.
  • the leg 208 is concreted in with its webs 209 in the opposite tunnel section, in which the webs 203 of the leg 202 are also concreted in.
  • FIG. 8 shows a schematic representation of a further joint tape, which is identical to the joint tape according to FIG. 1 except for another leg 210 projecting downwards. the leg 210 is longer than the leg 208 of the joint tape according to FIG. 1.
