Definitions

  • the invention relates to a device for storing reinforcing steel for connection areas of concrete structures.
  • a disadvantage of the known devices is their comparatively complex structure. This is noticeable in handling and economically.
  • the invention has for its object to provide a device for storing reinforcing steel, which is characterized by a particularly simple structure and which is versatile.
  • the invention is based on the finding that cardboard, in particular hydrophilic corrugated cardboard, is particularly suitable as a material for devices for storing reinforcing steel.
  • the invention relates to a device for storing reinforcing steel for connection areas of concrete structures according to WO-A-8 302128 in the form of an elongated, essentially strip-shaped, one-piece body, which has at least three longitudinal folding edges, can be embedded in the bending-out connection areas of the reinforcing steel are, the anchoring areas protrude from a wide longitudinal surface of the body which has spaced openings in the longitudinal direction.
  • the invention is characterized in that the entire body embedding the reinforcing steel consists of hydrophilic cardboard.
  • Cardboard is an extremely inexpensive material that can be easily processed.
  • the openings can be punched and folded edges can be pre-folded.
  • the material is light and easy to transport.
  • the hydrophilicity of cardboard has proven to be particularly advantageous for the use of devices for storing reinforcing steel.
  • the water of the wet concrete is absorbed by the cardboard and softens it.
  • the softened cardboard can then be pulled off particularly easily and removed without any residue. If necessary, the softened cardboard can simply be sprayed away with a water jet.
  • corrugated cardboard is particularly suitable because this material has high stiffness but flexibility at the same time. Furthermore, the surface of corrugated cardboard is smooth.
  • the reinforcement steels are only held in position by the strip surfaces themselves. It is advantageous if the internal distance between the two wide longitudinal surfaces corresponds approximately to the strength of the reinforcing steel. A slightly larger inner distance is acceptable as long as the reinforcement bars are adequately fixed in their position. With a much larger inner distance than the reinforcing steel thickness, however, the required hold is no longer guaranteed.
  • the device can be designed primarily for reinforcement steels of 8 mm thickness. The inner distance is then about 8 mm, possibly a little less. Reinforcing steels with 6 mm are not optimally held in this device, but the device can be used for this. The irons are given an additional hold by the narrow sides of the device.
  • the device is also suitable for iron with a diameter of 10 or 12 mm.
  • the flexible cardboard material only bulges out.
  • the internal distance can also be smaller than the thickness of the reinforcing steel, since the cardboard material used is flexible and with larger thicknesses, the strip is only bulged.
  • the strip generally has 4 folded edges. However, an embodiment with only 3 folded edges, in which case a broad longitudinal surface of the strip would rest on the narrow side of a narrow longitudinal surface, would also be considered.
  • the wide longitudinal surface in which the openings are provided is a surface which is not subdivided in the longitudinal direction in the folded state.
  • the openings provided in the strip preferably correspond to the strength of the reinforcing steel to be used, but can also be somewhat smaller, if appropriate also somewhat larger, because of the easy deformability of cardboard.
  • Two rows of openings are preferably provided in the strip, it then being advantageous to make the distances between the individual openings different.
  • the distances can be 20 cm in one row and 15 cm in the other row.
  • the row with shorter intervals is loaded when a lot of iron is required. Both rows can also be equipped.
  • a penetration of concrete into the free openings is not to be feared since the side provided with the openings Device is attached to the formwork.
  • a major advantage of the device is that, if desired, any number of further openings can be made in a very simple manner, such as by simply pushing them through, so that all special conditions can be taken into account.
  • the strip 1 shown in FIG. 1 consists of cardboard, openings 11 being spaced apart being punched in a wide longitudinal surface 6. Two rows of openings 17, 18 are provided, the distances between the openings in the rows being different.
  • the fold edges 2, 3, 4, 5, which are preferably prefolded, run in the longitudinal direction.
  • the lateral strip sections 9, 10 preferably have dimensions such that they overlap when folded. But they can also be designed so that they only or not even meet.
  • the dimensions of the strip in the longitudinal direction are arbitrary per se. A length of about 130 cm has proven to be suitable.
  • the width of the wide longitudinal surfaces is essentially determined by the amount of reinforcing steel embedded in the device and is preferably 6 cm.
  • the width of the narrow longitudinal surfaces 12, 13 is measured by the desired internal distance, which should preferably correspond to the thickness of the reinforcing steel 8.
  • the openings 11 also preferably correspond to the strength of the reinforcing steels 8. Their spacing and their arrangement are determined by the desired reinforcement.
  • the reinforcement steel used generally has a diameter between 6 and 12 mm. Steels with 8 and 10 mm are preferred.
  • connection areas 14 of the reinforcing steel 8 are embedded in the device, while the anchoring areas 15 of the reinforcing steel 8 are guided through the openings 11 and protrude.
  • the length of the connection areas 14 is usually 30 to 60 cm, often 45 cm.
  • the shape of the anchoring areas can be any.
  • the length of the anchoring parts 15 is usually 5 to 20 cm.
  • the anchoring part is designed as a bracket 19.
  • the connection areas can be accommodated together in one device.
  • the device is preferably closed by gluing. Sealing with adhesive strips has proven to be particularly simple and suitable.
  • FIG. 3 shows a side view of the device in the folded state.
  • the anchoring areas 15 of the reinforcing steels 8 protrude from the folded strip 1.
  • connection areas 14 of the reinforcing steels 8 shows a possible arrangement of the connection areas 14 of the reinforcing steels 8.
  • the arrangement is in itself arbitrary and depends on the number and length of the reinforcing steel.
  • the device according to the invention is used in a manner known per se, for which reference can be made, for example, to the explanations in European Patent 0 024 697.
