Definitions

  • the invention relates to a sealing device for sealing concrete joints.
  • these metal strips are fastened to a reinforcement arranged in the concreting section with solder wire or the like, or are inserted into appropriately shaped receiving slots on the reinforcement, so that the metal strip is approximately perpendicular and approximately symmetrical to itself forming abutting surfaces is arranged.
  • the sheet metal strip is then poured into the concreting sections so that it blocks the joint and prevents the penetration of moisture through the joint.
  • the sheet metal strips are usually used with a width of 300 mm or larger and a thickness of 3 to 4 mm.
  • the individual metal strips are cut and preformed in a workshop and connected to one another on the construction site by welding and soldering.
  • An incorrectly prefabricated sheet metal strip cannot easily be reworked at the construction site, which is why if the sheet metal strips are incorrectly prepared, the setting of the concreting sections is replaced by a new one Workshop processing can greatly delay.
  • the sheet metal strips are susceptible to corrosion, unless stainless sheet metal is used, but which does not bond well to the concrete. For a good connection between the sheet metal strip and the concrete, sheet metal strips covered with flash rust are therefore preferably used, since this results in a better connection between sheet metal and concrete.
  • a corroding sheet metal strip is dangerous in the long run, however, because rusting through cannot be ruled out. Furthermore, the sheet metal strips have a considerable weight due to their thickness and width, which means that a crane insert may be necessary for lifting and moving a sheet metal strip composed for a longer construction section. Furthermore, sheet metal strips are only used in the form of flat elements, since a special spatial shape is associated with considerable costs.
  • the sheet metal strip plates connected to one another by welding or soldering are particularly susceptible to corrosion at their seams, which represent a considerable source of danger for leaks.
  • sheet metal strips do not necessarily have to be set before the first concreting process, but can also be pressed into the viscous concrete shortly after the first concreting section has been poured. In this case, however, the concrete should be compacted in the area of the sheet metal strip in order to ensure an adequate connection between the concrete and the sheet metal strip and thus an adequate tightness.
  • the sheet metal strips can simply be attached to the reinforcement or subsequently pressed into the still viscous concrete, but their handling when cutting, bending and assembling is complex, and that, particularly because of their corrodibility, they pose a considerable risk of leaks represent.
  • Joint tapes made of elastomer material are also used to seal a joint between two abutting surfaces of two concrete sections.
  • the cross-section of the joint tapes is designed according to the labyrinth principle, the joint tapes being provided with trapezoidal or triangular grooves in cross-section, which lengthen the waterway while simultaneously reducing pressure.
  • joint tapes Proper installation of the joint tapes is a prerequisite for the fulfillment of their function, in particular a direct connection to the concrete must be made.
  • the greatest stress on a joint tape occurs during installation, which is why great efforts must be made to avoid local overstressing by expansion, kinking and squeezing in this phase.
  • the joint tapes may not be nailed, except on narrow outer edge strips which are only intended for this purpose. It is particularly important to ensure that the elastic joint tape legs do not fold over and form pockets in the concrete that can hardly be subsequently sealed. This can in particular form cavities, porous spots or grooves which open the water a way to bypass the joint tape.
  • joint tapes it is therefore necessary to fasten joint tapes at relatively short intervals to the reinforcements provided in the concreting sections, so that folding over is reliably avoided. Adequate tightness is only achieved if the joint tapes are embedded in the concrete.
  • the legs of joint tapes that run horizontally should be pulled up at an angle of approximately 15 "in order to avoid air pockets in the concrete on the underside of the joint tapes.
  • the joint tapes are delivered to the construction site as rolls and can be easily adapted to the course of the joint due to their flexibility. They are cut at the construction site and connected to one another by vulcanization.
  • the vulcanization is carried out with special vulcanizing devices by adding raw material under pressure and heat.
  • large subsystems me in which sections of the joint tapes of an entire construction section with all intersections and branches are combined, are delivered prefabricated to the construction site.
  • There are sets of right-angled molded parts but in general they are not sufficient for a complete sealing system, which is why the constructive processing of joint tape molded parts must be taken into account at an early stage when drafting the design.
  • joint tapes can be machined on the construction site in the case of simple straight-line or right-angled construction sections; however, in the case of more complicated construction measures, planning must be carried out in advance and joint tape molded parts must be prefabricated. In addition, considerable effort is required when attaching the joint tape to the reinforcement, or if the joint tape is not properly fastened there is a risk that the joint tape will fold over, thereby causing voids, porous spots or nests.
  • joint tapes with lateral sheet metal strips have been developed, in which the sheet metal strip is vulcanized into the joint tape.
  • joint tapes are complex and therefore expensive and have the same problems in handling as the metal strips discussed above.
  • EP 0 418 699 A1 describes a sealing device for injecting sealing material into the joint area, which consists of a hood-shaped profile which is open in cross section and which is mounted on the concrete surface with the free longitudinal edges of its side areas, so that a flow channel for the sealing material between the Profile and the concrete surface is formed.
  • the sealing material is introduced into the flow channel under high pressure and exits between the free longitudinal edges of the profile on the concrete surface at defects in the concrete.
  • a further sealing device described therein consists of a body which consists of a foam or foam tape, preferably with a rectangular cross-section, which has pass-through pores and which is mounted lying on the concrete surface, so that the flow channel for a sealing material is formed by the body itself, the sealing material emerging from the through pores into the joint area.
  • sealing hoses are known which are described, for example, in CH-PS 600070, which consist of a support body in the form of a helical spring which is surrounded by a first, braided injection hose, which in turn is surrounded by an outer, mesh-like porous hose. After assembling these hoses and concreting the second concreting section, a sealing material is pressed into the hose-like sealing device, which is to emerge from defects in the concrete.
  • the swelling agent is a hydrophilic mass which is embedded in a carrier, usually chloroprene rubber.
  • the primary task of the carrier material is to impart stability and elasticity to the swelling agent.
  • the hydrophilic (water-absorbing) component absorbs water molecules and thereby increases their volume by 1.5 to about 4 times. This creates a pressure of up to 6.5 bar, which fills the surrounding cavities and is intended to make them impermeable to water.
  • swelling agents it should be taken into account that the swelling mass does not expand suddenly, but slowly over hours or days, and consequently can only be used to a limited extent in alternating areas with wet and dry periods.
  • a striking advantage of source tapes, which is why they are used frequently, is their speed, joints between different materials such. As concrete, plastic, concrete / iron, etc., reliably seal.
