Definitions

  • the invention relates to a shrink pipe shoe for easy-to-use placement and reliable stabilization of the alignment of a shrink pipe that can be connected to a joint tape relative to the joint tape, a shrink pipe shoe device and a method for connecting a shrink pipe to a joint tape, preferably arranged in a construction joint, such as an internal one, for producing predetermined cracks in a wall made of concrete.
  • Watertight structures are made with concrete, also known as fresh concrete, with a high water penetration resistance. This must also withstand the requirements of watertight structures with concrete in terms of chemical attacks. Watertight structures are generally referred to as buildings or structures with or made of concrete that are built without additional external, for example skin-like, sealing and that are able to prevent the passage of water in liquid form due to the building material alone and special structural measures, e.g. joint sealing, crack width limitation.
  • watertight concrete structures are those that are built without additional external surface sealing and that prevent the passage of water in liquid form due to the concrete alone and structural measures, such as joint sealing and crack width limitation.
  • waterproof concrete also called white tub
  • the structures should also meet the requirements of use class A according to the above guideline, namely that water penetration in liquid form is not permitted, no damp spots appear on the surface, no condensation occurs.
  • the waterproof concrete must therefore be impermeable to water, but preferably permeable to water vapor.
  • the floor slab as a base slab or foundation slab and the walls provided on this by means of concrete casting are designed as a closed tub that encloses the building and extends at least, e.g.
  • joints are created.
  • a joint is also referred to as a gap between two components or structures that abut one another without being connected to one another.
  • joints are essentially referred to as movement joints, settlement joints, construction joints and dummy joints in the sense of the invention.
  • Reinforced concrete can usually be produced in situ.
  • Reinforced concrete is a composite material whose load-bearing capacity is achieved through the interaction of steel and concrete.
  • Steel inserts referred to below as reinforcement, can include reinforcing steel bars, reinforcing steel mats, etc., which can absorb tensile forces, increase the compressive strength of the concrete and limit the formation of cracks in the component.
  • the concrete usually also provides rust protection for the reinforcement and thus also serves as fire protection.
  • joint tapes are used, such as plastic joint tapes with PVC or synthetic rubber, which run at least partially horizontally in the old concrete part of the building, with their central transverse axis aligned vertically, for example at least largely transversely to the floor slab as a base or foundation slab.
  • the construction joint tapes are therefore intended to seal the construction joint that inevitably arises as a result of the delay in subsequent concreting, which normally has no visually recognizable, often barely measurable joint gap, even if the joint gap is barely visible or not visible during a thorough inspection.
  • pressing or compressive water can penetrate from the outside into the waterproof structure or into the interior of the building, even through barely visible joints.
  • the purpose of the joint tape is to seal this construction joint in accordance with the assumed design water level.
  • the cracks that appear in the new concrete part due to the hardening of the fresh concrete lead to leaks in the walls, so that water penetrates through the walls from the outside, even if the construction joint, which may also be referred to as a separation crack, is sufficiently sealed by the joint tape or the construction joint tape.
  • the connector is arranged as a connecting means between a star pipe, also called a shrink pipe, and a joint tape, whereby the connector has a base plate that has a top and a bottom.
  • a receptacle protrudes from the top of the base plate and is connected in a sealing manner to one end of the star pipe. wherein surface elements are arranged protruding from the edge of the base plate.
  • the surface elements comprise surface parts on the sides which, in a desired installation position, lie sealingly against the joint tape. It is apparent that the surface parts are not sufficiently connected to the joint tape in the desired installation position, so the publication proposes that the connector should have additional retaining brackets which are both fixed to the joint tape and connected to the surface elements in order to ensure that the star tube is securely held to the joint tape.
  • the wings arranged in the edge area of the base plate are aligned perpendicular to the base plate and are formed over the base plate with a part of their length protruding beyond the base plate on the circumference to such an extent that the surface elements are to be additionally reinforced by the wings.
  • the task of the shrinkage pipe shoe to be provided to ensure that the shrinkage pipe shoe can be easily connected to the joint tape by the inexperienced user on site, given the robust procedure on construction sites, and that the shrinkage pipe can also be attached to the shrinkage pipe shoe.
  • the conventional device is not very self-explanatory for the inexperienced user due to the complicated structure of the device for fixing or locking it to the joint tape, so that such a device for fixing the star pipe or shrink pipe via the device to the joint tape is not recommended.
  • the task of the shrink pipe shoe according to the invention to be self-explanatory to the inexperienced user based on its structure alone, so that even the inexperienced user on the construction site can easily recognize their function and interaction with the joint tape and shrink pipe based on the spatial arrangement of the individual components of the shrink pipe shoe in relation to one another.
  • shrinkage pipes or so-called crack control elements are cast into the new concrete part of the wall to reduce stresses and to induce cracks in walls or parts of them in a controlled manner.
  • a shrinkage pipe is cut into the areas opposite the end facing the joint tape to accommodate the part of the joint tape that protrudes above the old concrete part.
  • cutting the shrinkage pipe on site only results in the shrinkage pipe being cut roughly and that the width of the cut surface may not correspond to the width of the joint tape, so that there is a risk of leakage due to water penetrating through the cut surface of the shrinkage pipe into the interior of the wall.
  • the distance between the concrete and the attached shrinkage pipe is, for example, 5 cm.
  • a strip of metal is pressed into the fresh concrete so that the conventional shrinkage pipe is given the necessary lateral support. It turns out, however, that the strip of metal is not sufficient to reliably provide permanent lateral guidance and alignment of the shrinkage pipe, especially during concreting, so that due to a lack of vertical alignment of the shrinkage pipe, for example, the formation of predetermined cracks in the concrete is restricted or does not show the desired required course in the concrete.
  • the shrinkage pipes must be connected to the joint tape or the connecting joint on the base plate to the wall in accordance with technical regulations in order to provide targeted crack guidance in the concrete as desired. Only by precisely aligning the shrinkage pipe both to the joint tape and to the concrete can a complete seal be achieved, for example in a watertight room such as a basement, although this may require concreting in the area of the shrinkage pipe without leaving any voids.
  • one end of the shrinkage pipe in this case the lower end facing the joint tape, is improperly cut on site, so that despite filling part of the shrinkage pipe interior with fresh concrete, sealing of the area between the joint tape and the shrinkage pipe is inadequate and cannot be guaranteed.
  • the invention is intended to suppress the migration or creeping of water along the upper part of the joint tape over the shrinkage pipe interior partially filled with concrete into the upper part of the shrinkage pipe.
  • the joint tape which is intended to seal the horizontal seal between, for example, the base plate and the wall to be constructed or cast on the base plate or between the old concrete part and the new concrete part of a wall, keeps the interior of the waterproof structure free of water.
  • the invention is also intended to make it possible for cracks to occur as predetermined crack joints in the wall as a result of controlled cross-sectional weakening over the entire surface, without the wall being permeable to water.
  • the invention is also intended to make it possible to quickly install a shrink pipe and seal its connection with the joint tape, so that controlled crack formation in the wall can also be carried out reliably.
  • the shrinkage pipe should be able to be tightly connected not only with joint tapes, such as construction joint tapes, but also with other types of joint tapes.
  • auxiliary claims relate to preferred embodiments and further developments of the invention.
  • Another subject matter of the invention relates to the use of the shrink pipe shoe for easy-to-use installation and reliable stabilization of the alignment of a shrink pipe that can be connected to a joint tape and/or can be attached or attached against the shrink pipe shoe, e.g. opposite or with the shrink pipe shoe and/or opposite or with the joint tape, in joints, such as construction joints, wherein, among other things, the shrink pipe shoe can be connected to the joint tape and/or the shrink pipe can be connected to the shrink pipe shoe, e.g. intimately, preferably glued and/or, e.g. thermally, welded, to provide the advantageously sealing or sealing connection.
