Definitions

  • the invention relates to a method for producing a portable prefabricated collecting basin made of concrete for water-polluting liquids, according to the preamble of patent claim 1.
  • a method of the type mentioned is known from the operational practice of precast concrete manufacturers.
  • the prefabricated sump trays produced in this way are produced at a central plant and then brought to the place where they are installed.
  • Such drip pans are used, for example, for cleaning systems for motor vehicles or rail vehicles, in particular tank trucks.
  • DE-A-38 09 963 discloses a method for producing a trough-shaped or basin-shaped collecting space for water-polluting liquids stored in storage containers. With this method, collecting rooms with very good long-term tightness can be produced, but it is considered a disadvantage here that this known method is practically only for the production of collecting rooms on the spot, i. H. at their intended location.
  • the concrete used is advantageously used not only for static purposes but also as corrosion protection for the sheet metal pan embedded on all sides and as a sealant in the concrete.
  • a coating of the surface of the drip pan is therefore no longer necessary, which means that this labor-intensive and cost-intensive step can be completely eliminated.
  • the special sequence of the process steps ensures that the sheet metal tray is completely surrounded by the concrete without cavities or air pockets, which also provides excellent corrosion protection in the long term.
  • the concrete layers can of course, as usual, be provided with reinforcements in a known manner.
  • a further embodiment of the invention provides that the circumferential sheet metal strip is provided with a welding flange at its upper edge prior to welding to the sheet metal plate to the sheet metal trough, which delays the setting in the installed surface of the sheet metal strip at the end of the second process step in the plane of the free surface of the filled, set set fresh concrete. On the one hand, this simplifies the welding process and, on the other hand, it compensates for dimensional tolerances and position deviations when the sheet metal strip is embedded reached in the concrete of the side walls of the sump.
  • a second solution to the stated problem is achieved according to the invention by a method of the type mentioned at the outset with the characterizing features of patent claim 5.
  • the advantages described on the basis of the solution according to patent claim 1 are also achieved with this alternative method.
  • the method according to claim 5 is particularly suitable for shallower drip pans with relatively low side walls, in which the sheet metal strip of the sheet metal tub embedded therein has a relatively low height.
  • the ventilation opening or openings are expediently closed by welding on one sheet metal cover each. Reinforcement can of course also be provided here.
  • the formwork used corresponds to conventional negative formwork, as has been used previously for the production of drip pans, and is usually arranged on a vibrating table in order to achieve the desired compaction when or after the various concrete layers have been laid.
  • a negative formwork 3 which is composed of formwork parts 30, 30 'and 31, is used for the production of the collecting trough 1 shown here by way of example.
  • the formwork parts 31 limit the side walls 11 and 12 of the sump 1; the formwork part 30 delimits the side wall-facing part 10 of the bottom 10, 10 'of the collecting trough 1, and the formwork part 30 'laterally delimits the part 10' of the bottom 10, 10 'of the collecting trough 1 facing away from the side wall , ie in the manufacture of the drip pan 1, the bottom 10, 10 'is at the top and the side walls 11, 12 extend from there downwards.
  • a sheet metal trough 2 which is composed of a sheet metal strip 21 encircling the side walls 11, 12 and a sheet metal sheet 20 embedded in the floor 10, 10' is.
  • the metal strip 21 is provided with a welding flange 22 at its upper end in the figure shown here.
  • the sheet metal plate 20 is welded around its edge 20 'in a liquid-tight manner by means of a weld seam 23.
  • the production of the drip pan 1 proceeds as follows in the present example:
  • the circumferential metal strip 21 is introduced into the prepared formwork 3 without this contacting the formwork 3.
  • the sheet metal strip 21 can be provided, for example, in the region of its welding flange with suitable stop means for the attachment of ropes or the like holding means. If the circumferential sheet metal strip 21 is aligned and after a reinforcement between the formwork 3 and the sheet metal strip 21 has optionally been introduced beforehand or subsequently, the formwork 3 is up to the level of the line 13, i. H. up to the upper edge of the sheet metal strip 21, filled with fresh concrete set with a setting delay. Compression takes place in parallel or subsequently.
  • the sheet 20 After filling the formwork 3 with setting delayed fresh concrete up to the level of line 13, the sheet 20 is placed, the laying being carried out so that air pockets and voids between the sheet 20 and the lower part 10 of the bottom 10, 10 'of the collecting pan 1 forming fresh concrete set with a delay in setting can be avoided.
  • the two parts After this placement of the metal sheet 20 and, if necessary, congruent alignment to the circumferential sheet metal strip 21, the two parts are welded along the circumferential edge 20 'of the sheet metal plate 20 and the circumferential welding flange 22 of the sheet metal strip 21, a continuous circumferential weld seam 23 being formed.
  • the metal sheet 20 can also be welded together from several partial sheets before or after being placed on it.
  • a second layer of fresh concrete is applied to the upper side of the sheet metal plate 20, which fills the formwork 3 up to the height of the upper edge of the formwork part 30 '.
  • the setting delay of the setting delay Fresh concrete set for the lower part of the collecting trough 1 is set so that both fresh concrete layers, ie the fresh concrete layer below line 13 and the fresh concrete layer above line 13 set essentially simultaneously. If necessary, reinforcement can also be introduced into the upper fresh concrete layer above line 13 before or when the fresh concrete is introduced. Due to the fact that all concrete layers set essentially simultaneously, a homogeneous concrete body also results in the area of line 13, which has no weak zones and therefore no tendency to form cracks.
