Definitions

  • the invention relates to a device for producing a layer of concrete and the like, which is divided into individual fields, in particular a carriageway ceiling, airfield runway or the like, the concrete being applied to the substrate in a predetermined thickness, with a sword-like separating member for incorporation of slits running transversely to the concrete surface at a distance corresponding to the field width and / or field length into the not yet hardened or set concrete and for introducing into the slots a separating film or separating layer for the concrete masses located on both sides, the separating member being attached to an over the carrier to be produced is slidably mounted and at least one vibrator for local thixotropic conversion of the concrete as well as a device provided with outlet openings for dispensing the separating agent into the generated slot part on the carrier or on the separating member are held.
  • Such a device is known from DD-A-229 176.
  • Your sword-like separating element has approximately the shape of a circular section and the outlet openings for the separating agent are located behind the lowest point of the separating element when viewed in the direction of displacement. Also seen in the direction of displacement, there is only a relatively short end piece of the separating member behind the outlet openings and also only partially protruding into the slot part produced. This is unable to keep the concrete masses on both sides of the slot part currently being produced apart until the release agent introduced has formed a closed separating film or separating layer. Due to this imperfect separating film or separating layer, the concrete masses on both sides can partially approach each other again and set together. As a result, individual fields are created that are connected to each other by concrete bridges and are therefore not real fields in the intended sense.
  • the object of the invention is therefore to develop a device of the type described above so that the slots created by the sword-like separating member can be completely filled with the help of the separating film or separating layer produced, so that the concrete layer is effectively divided into individual fields.
  • the invention proposes that the device is designed according to the preamble of claim 1 according to the characterizing part of this claim. Because the separating member of this device is equipped with a support member which is laterally offset relative to its plane and which is located at least to the side of the area of the separating member provided with outlet openings and it also projects beyond this area towards the rear, that is to say counter to the direction of displacement, these are each removed with the help of the separating member locally spaced-apart concrete masses are kept at a sufficient distance from each other so that the separating agent introduced into this area has sufficient time to form a closed separating film or separating layer which fills this area. If the two concrete layers then approach each other again due to the device being pushed further and thus released by the support member, this is only possible until it hits the separating film or separating layer produced in this area.
  • the insertion of the slit and the shaking or the local thixotropic conversion must be coordinated with one another in such a way that the slit is maintained at least until the liquid or pasty release agent introduced has formed the closed separation layer. If the separating layer is very thin, ie film-like, then the slot walls must approach each other or the separating film or separating layer formed before and or during the hardening of the concrete. In this case one speaks of a "press joint".
  • the majority of the concrete mass forming a concrete field can set in a completely normal manner.
  • the upper slot opening can be covered and / or smoothed by a suitable device, so that a continuously flat concrete surface is ensured.
  • the slot can extend to the middle of the Concrete layer or extend close to the bottom of the latter. This prevents the release agent from flowing out before it solidifies.
  • the separating agent is expediently introduced into the lower and middle region of the slot. How high you fill the slot depends on the concrete, the type of shaking and the physical behavior of the release agent after it has been introduced into the joint.
  • the release agent is only compressed a little when the concrete solidifies, the slot is filled higher than when the release film or release layer is pressed together more strongly.
  • the dosage should be chosen so that the release agent does not flow beyond the upper slot edge after solidification.
  • the entire work steps are expediently carried out fully or at least semi-automatically by means of a suitable control. If necessary, especially during the cold season, the concrete and / or the release agent can be heated in the immediate working area.
  • the separating member has a wavy, zigzag, meandering or similarly uneven cross-section.
  • wavy, zigzag or meandering joints can be produced in cross-section, the separating layer naturally also having this cross-sectional shape.
  • the fields on both sides are able to transmit lateral forces, i.e. forces that act perpendicular to the road surface. Press or level running vertically to the road surface Room joints cannot transmit transverse forces, which is why you have to install the iron anchors mentioned below if necessary under the separating film or separating layer.
  • a further embodiment of the device is characterized in that the separating member forms a displaceable structural unit with the device for applying the separating means. In the case of continuous joint production, both can be pulled through the concrete together as one unit.
  • the separating member is advantageously hollow and provided with outlet openings or at least channels for the separating agent, the latter being connected or connectable to a storage container and opening to the outside or being open at its end remote from the container.
  • the outlet openings, nozzles or the like are arranged at least on the lower area of the structural unit in the working position. This is advantageous if the separating member extends over the entire length of the joint to be produced and this joint is filled when the separating member is pulled out of the concrete layer.
  • the press or space joint is preferably produced continuously and this also allows the possibility of a joint which is uneven in cross section
  • a carrier 3 along which the device 4 according to the invention in the exemplary embodiment is mounted so as to be movable perpendicular to the image plane.
  • the carrier can be, for example, a T-profile with a T-crosspiece below.
  • the longitudinal direction of the carrier 3 runs parallel to the press joint 5, 6, 7 (FIGS. 5-7) or space joint 8 (FIG. 4) to be produced using the device 4.
  • the carrier can be raised or lowered or extended in this direction transversely to its longitudinal axis or the device can be raised and lowered in this direction.
  • Essential parts of the device 4 according to the invention are or are preferably two vibrators 9, 10 or vibrator groups, in the latter case the vibrators of each vibrator group standing one behind the other perpendicular to the image plane. It is preferably high-frequency vibrators. They are elastically supported on a frame 11 of the device in a known manner, which is expressed by symbolically drawn springs 12 and 13. In order to achieve good longitudinal and transverse guidance, wheels 14, 15 or wheel groups for transverse guidance are provided on the frame, that is to say wheels which can be rotated about vertical axes. At least one wheel lies on the left and right flank of the T-longitudinal web 16 or, as in FIG. 1, on the T-transverse web 17. At least one left wheel group 18 and one right wheel group 19 are assigned to the T-crosspiece 17. Their wheels have horizontal bearing axles and they serve to guide the device in the vertical direction.
  • the device can of course be in any other known Be carried out in a manner and therefore it is not tied to the use of a T-beam.
  • other known sliding elements, sliding shoes and the like can be provided instead of wheels or rollers.
  • a double-T, U or other known profile could also be used as the beam cross-section.
  • FIG. 1 An important component of the device 4 is also a sword-like separating member 20.
  • it is connected to a device 21 for applying a separating means 22 or combined as a unit 23.
  • Both the sword-like separating member 20 and the device 21 or the structural unit 23 are shown in FIGS. 1 to 3 only shown schematically.
  • a flat sword-like separating member 20 is used, while the separating member 20 of FIG. 2 has a zigzag-shaped cross section. The latter leads to a zigzag-shaped press joint 7 (Fig. 7).
  • a press or space joint which is wavy in cross section is naturally produced, for example according to FIG. 6.
  • a hollow or double-walled separating element 20 can be used, which has outlet openings or nozzles arranged one above the other.
  • outlet openings can also be located at the lower end 27 of the sword-like separating member 20, in which case it is then expedient to dispense with an oblique course of the lower edge.
  • the release agent can be distributed evenly over the entire joint height.
  • a support member 34 is located directly to the side of the channels 25 of the separation member 20. It extends counter to the direction of travel 24, that is to say the direction of displacement of the assembly 23 along the carrier 3, to the rear.
  • its length protruding to the rear, in the direction of travel corresponds approximately to the length of the separating member 20 in its upper region.
  • it can also be larger or smaller, a range of about 5 to 50 cm being possible. 3, it can protrude somewhat beyond the separating member 20.
  • the lower edge of the support member 34 is expediently moved close above the base layer 1.
  • the purpose of this support member 34 is to act on a flank of the joint created in a supportive manner until the release agent has been applied in this area.
  • This joint flank remains largely when the separating member 20 continues, while the the opposite wall is gradually approaching, but cannot come into contact with it due to the release agent that has now been introduced. This reliably prevents the two slot walls from merging at different speeds, which would be possible without this support element due to the thixotropic condition of the concrete in this area.
  • the total width of separating member 20 and supporting member 34 determines the joint width.
