Definitions

  • the invention relates to a concrete paver with a device for producing a longitudinal glue joint running in the production direction by means of a jointing agent reaching into the area of compacting units, in particular in the form of immersion vibrators and a pressure plate connected downstream thereof, with a smoothing device and possibly with a jointing agent following device for wetting or filling the joint formed.
  • concrete ceiling paver of the Fugensentner consists of a short erdichtungsaggregaten in front of the V-ended tubular portion of the concrete ceiling paver is continuously introduced an elastic joint sealing profile in the still plastic concrete by the in the course of the forward movement.
  • the entry end of the pipe section is located on a vertical bulkhead of the paver, behind which the concrete supply is poured.
  • the joint sealing profile can then be easily inserted into the pipe section from a coil arranged in front of this wall.
  • This known arrangement is not suitable for concrete pavers without such bulkheads, which drive onto the paving material heaped up in front of them and distribute them automatically and process them to the concrete ceiling.
  • Another disadvantage is that in the known concrete paver, the pressure plate and the smoothing devices follow the joint former, so that there is a risk that the smoothing movements (especially when using screed boards) will affect the course of the joint.
  • a concrete paver which does not require a bulkhead and can therefore also process paving material that has been piled up in front of the paver.
  • Attached to this paver is a profiled steel strip that forms the longitudinal joint, which extends beyond the rear end of the concrete paver to the area of the broom line.
  • a longitudinal joint is obtained with a dimensionally stable cross section and good straightness;
  • the operation of the concrete paver is made more difficult by this long section steel strip, especially at the start of production and at the end of production.
  • the broom line must maintain a predetermined distance corresponding to the length of the section steel strip.
  • the object of the invention is to provide a concrete ceiling finisher of the type mentioned, we l - cher with simple construction and easy handling longitudinal provides false joints of good dimensional accuracy and straightness and can process paving material in front of the paver.
  • the joint former comprises a joint preformer in the area of the pressure plate and a joint main former separate from this in the area of the smoothing device, in particular the screed, of the concrete paver.
  • the main joint former is located in the area of the smoothing device, that is to say in an area with already compacted and therefore less plastic concrete, which is then subjected to practically no vibrations, shaking movements or the like.
  • the longitudinal joint created by the main joint former therefore has a high level of dimensional stability.
  • the task of the joint preformer aligned with the main joint former is to clear stones or the like out of the way so that the main joint former can easily cut into the already more or less compacted concrete. Since the joint preformer is still in the area of the plastic concrete, it does not pose any difficulties for it to clear even larger stones.
  • the joint preformer be arranged in the region of the front edge of the pressure plate.
  • the F preferably approximately sword-shaped ugenvorformer is releasably attached to the pressure plate.
  • the underside of the pressure plate is then continuously smooth on the joint preformer in the area of the front edge, so that the concrete is compacted extremely evenly. This is of great importance for the ceiling quality.
  • the main joint former passes under the screed and is preferably coupled in height to it.
  • the result is consequently a dimensionally stable joint formation in this at least above f l ambalich still moving situated concrete ceiling.
  • the height coupling with the screed that determines the final ceiling level ensures that an exact joint depth is maintained.
  • the F ugenmaschineformer reciprocate horizontally via a sliding or roller bearing on the supporting and reciprocable smoothing board.
  • the preferably approximately sword-shaped main joint former is pivotally connected to a concrete paver frame around a vertical axis in the region of the front end of the main joint former. This ensures the correct orientation of the main joint former with a particularly simple construction, since it automatically adjusts itself in the manner of a rudder according to the direction of the concrete material flowing past.
  • the Main joint former on one or the concrete paver frame is laterally displaceable.
  • a swivel arm connecting the main joint former to the concrete paver frame is preferably used here.
  • a joint preformer provided with a vibratory drive is provided in the region between the pressure plate and the joint main former.
  • This preformer ensures a path free of aggregates for the subsequent main joint former under all operating conditions, especially if the main joint former immediately follows the joint preformer. All that is required is a small movement gap for the shaking movement of the joint preform.
  • the joint preformer on the pressure plate leading edge can be in many cases are omitted, so that the changeover is easier when attaching an intermediate formwork.
  • the joint preformer between the pressure plate and the main joint former can be easily removed by simply pulling it upwards. Lateral position adjustment of the joint preform is unnecessary if it is guided laterally in a fork that is fixed to the pressure plate or to the paver frame.
  • the joint preformer is attached to a vertical support on which a vibratory drive, preferably an unbalance motor, is held.
  • the vertical support can be mounted on a frame-fixed suspension fork via rubber elements, which makes it easier to remove the joint preform upwards.
  • the joint preformer in the area of the fork can be connected to the pressure plate or to the concrete paver frame by means of a detachable elastic strap.
  • Such tensile tapes can practically not be bent in the band plane.
  • examples of such tapes are the fiber tapes which are customary for box or package packaging or for packaging pallet loads, in particular glass fiber tapes. These are extremely tear-resistant, weather-resistant and available at low cost.
  • the tape would have to be bent in a first bending section around an axis parallel to the flat side of the tape from the vertical feed direction into the horizontal longitudinal direction of the groove and due to the tensile rigidity and then be twisted in a second bend section by 90 ° around its longitudinal axis so that it comes to rest in the vertical longitudinal plane of the groove.
  • the first and second bend sections must be below the top of the concrete ceiling, with the result that the paving material on both sides of the joint is strongly churned.
  • the broad side of the band is perpendicular to the vertical longitudinal plane of the groove.
  • the main joint former is provided with a feed for at least two joint sealing tapes arranged one above the other in the joint.
  • the at least two joint sealing strips arranged one above the other prevent the groove side walls from caking in a sufficiently large groove height range. Due to the division into several narrower bands corresponding to the dimension of the feeder is perpendicular to the vertical F ugenebene reduced accordingly. The installation material is only slightly disturbed by the feed. The subsequent screed ensures reliable Elimination of any impairments to the concrete structure.
  • the feeder feed the tapes into the joint at a distance from one another.
  • the distance can be up to 5 mm, for example, so that the effective height of the joint area secured by the strips is correspondingly increased. With the stated distance up to a maximum of about 5 mm, the desired opening of the dummy joint is nevertheless ensured.
  • a simple construction and reliable function of the feed are ensured if a flat feed pipe adapted to the joint cross section is provided for each band, with a first bend section around an axis parallel to the flat side of the feed pipe and with a second bend section with twisting of the feed pipe around its longitudinal axis.
  • a width of the main joint former which at most only slightly exceeds the joint width, while being inexpensive to manufacture and with high mechanical stability, is achieved by the main joint former being formed with the following parts which are rigidly connected, preferably worn, to one another, a plate-shaped lower part, a plate-shaped upper part and the guide tubes, which form one Fill in the L-shaped gap formed between the lower and upper part.
  • the feed is therefore integrated with the main joint former.
  • a feed for at least one joint sealing profile is provided on the main joint former, and a device for wetting the profile.
  • the joint sealing profile pulls
  • the wetting liquid wicking similar with in the groove, so that special constructional measures, such as D ruck apparatus for supplying the wetting agent is unnecessary.
  • a filling funnel can be provided at the input end of a guide tube that receives the joint sealing profile and inserts it into the joint.
  • the invention further relates to a method for producing a longitudinal joint with the help of a concrete paver, in particular with the features according to the invention mentioned above.
  • the principal function of the Lssensscheinfuge is namely a predetermined breaking point already satisfied if the invention is wetted in accordance with the joint with a sticking together of the F ugenflow practitioner preventing release agent and / or setting accelerators.
  • a joint sealing profile eg sealing tape
  • a waxy release agent is preferred. It can be sprayed onto the joint walls, for example. The structural effort for this is advantageously low; relatively little release agent is required.
  • the joint be filled with support material, preferably sand or bentonite. You can also foam out the joint.
  • the invention also relates to a concrete paver with a device for producing a longitudinal apparent joint running in the production direction and for installing at least one joint tape, comprising one in the area between compacting units, in particular in the form of vibrators and a pressure plate arranged downstream of the latter. and a smoothing device, in particular smoothing screed, arranged joint former, which is provided with a feed for the at least one joint band.
  • Such a concrete paver is known (DE-AS 15 34 258) and DE-OS 32 21 028).
  • a single band is fed through the hollow joint former to the joint formed behind the joint former.
  • the tape used must be elastic so that it can bend around a horizontal transverse axis lying in a vertical plane within the joint former ( Figures 2 and 3 of DE-AS 15 34 258).
  • the joint former ends at a distance in front of the subsequent smoothing device (smoothing plate or smoothing board). The depth of the joint thus essentially corresponds to the width of the band, since a deeper joint in the area below the band would be pressed by the smoothing device.
  • the band which is made of relatively soft material, must be inserted relatively deep into the joint, in order to avoid damage, for example, from a subsequent broom line device, with the risk that the dummy joint edge will become irregular.
  • the joint former must be made relatively long, since a greater curvature of the band in a vertical plane containing the band side surface is difficult to achieve.
  • a groove can be made with a depth that far exceeds the total width of the at least one joint strip.
  • the at least one joint tape extends in the area of the surface of the concrete ceiling; the joint area below the at least one joint tape is essentially retained.
  • the feeder bend the at least one tape about an axis parallel to the flat side of the tape and twist about the longitudinal direction of the tape.
  • the tape can be taken from a tape supply, e.g. Roll, are guided into the joint former above the concrete ceiling and inserted into the joint lying in a vertical plane with a horizontal longitudinal direction.
  • the bend is 90 °, for example, as is the twist.
  • the length of the joint former (in the conveying direction) can be shortened compared to the known shape, since the radius of curvature of the band can be selected to be comparatively small when it is bent around an axis parallel to the flat side of the band.
  • the mechanically stable band can be inserted into the groove at a reduced distance below the surface of the concrete ceiling, since the risk of damage from a subsequent broom line device is significantly reduced.
  • the feeder introduces at least two belts one above the other into the joint.
  • the concrete ceiling paver shown schematically in FIGS. 1 and 2 bears the reference number 10.
  • the concrete ceiling paver is supported with drives of the usual type, in particular with lateral caterpillar tracks 12 indicated by dashed lines in FIG. 1, on the base 14 or on lateral ones (not shown) careers.
  • the direction of manufacture is indicated by an arrow A in FIG. 1.
  • the concrete paver 10 has distributor plates 16 which are connected to one another via a pipe 18.
  • the tube 18 is mounted on a support 22 on a frame-fixed tube 21 transversely to the production direction A with the help of a movement drive, not shown, to and fro.
  • the distributor plates 16 are followed by a metering slide 26 which is pivotably mounted about a horizontal transverse axis 28 fixed to the frame in order to be able to supply a subsequent pressure plate 30 with installation material 20 in a predeterminable amount, in particular layer thickness.
  • the structure and the control of the metering slide 26 can correspond to DE-OS 32 32 020.
  • Immersion vibrators 34 of conventional construction are arranged between the pressure plate 30 and the shield 32 of the metering slide 26. Together with the pressure plate 30, these form compression units for the installation material 20.
  • an approximately sword-shaped joint preform 38 is detachably attached to the pressure plate in a manner not shown in detail. Since its vertical rear edge 40 is at a comparatively small distance from the front edge 36 in relation to the length a of the pressure plate underside 42, the underside 42 is practically free of elevation, so that a uniform compression of the installation material 20 by the pressure plate 30 is ensured.
  • the joint preformer 38 has the function of coarser components of the one to clear building material 20, in particular stones, from the path of a subsequent joint main former 44 which is in alignment with the joint preformer 38. This is facilitated in that the joint preformer is still in effect b e-rich the pokers is 34, ie in a region in which the mounting material 20 is still readily flowable.
  • the main joint former 44 passes under a following on the pressure plate 30 screed 46. Its forward end 48 is slightly pointed to granular structures of the paving material to be able to reject readily 20 behind the joint preformer 38 accordingly slightly into the path of the trailing F ugenhauptformers 44 have penetrated.
  • the main joint former 44 is provided on a holding frame 50 which surrounds the screed 46 in a U-shape. About this holding frame, the joint main former 44 is supported on the screed 4. 6 This is indicated schematically by a roller 54 which is rotatably mounted on an upper longitudinal spar 52 of the holding frame 50 and has an axis of rotation parallel to the production direction A. The roller is supported on the top 56 of the screed 46.
  • the roller 54 and a clear movement distance between the underside 58 of the screed and the upper longitudinal edge 60 of the main joint former 44 permit the usual back and forth movement of the screed (double arrow B in FIG. 2 transverse to direction A) without the main joint former 44 being carried along. Due to this height coupling of the main joint former 44 to the screed 46, a defined constant joint depth b is ensured since the screed 46 defines the concrete ceiling surface 62.
  • the main joint former is connected to the concrete paver frame 24 via a swivel arm 64.
  • One end of the latter is leaned against a vertically extending frame support 66 (vertical axis 68) and the other end is connected in an articulated manner to the holding frame 50 (vertical axis 70).
  • the articulated connection between the arm 46 and the holding frame 50 permits a vertical displacement of the frame 50 relative to the arm 64, corresponding to the respective height setting of the screed 46. This is indicated in FIGS. 1 and 2 by the fact that a vertical frame leg 72 of the holding frame 50 is divided into two vertically hinged eyes 74 of the rectangular frame-like frame 64 are supported so as to be height-adjustable.
  • the frame leg 72 is rigidly connected to the main joint former 44 in the region of the front end of the main joint former. In this way, the desired orientation of the main joint former results automatically in the manner of a dragged rudder parallel to the production direction A.
  • the swivel arm G4 is held in the desired angular position by appropriate adjusting means (joint main former 44 in alignment with the joint preformer 38).
  • the main joint former 44 can be pivoted laterally into a waiting position 78 indicated by the broken line in FIG. 2.
  • This pivoting movement of the arm 64 can be brought about by hydraulic cylinders or the like.
  • a particularly simple adjustment device is shown, which consists of a spindle 80 with a handwheel 82 which is mounted, for example, on a horizontal frame part 84 of the concrete paver frame 24 so as to be axially immovable but rotatable about its axis.
  • the spindle 80 engages in a spindle nut 85 a, which is non-rotatably mounted on the arm 64 but pivotable slightly about a vertical axis 86. Accordingly, the spindle 80 can also be pivoted slightly on the frame part 84 via a corresponding intermediate sleeve, not shown, about a vertical axis 88, in order to allow the spindle 80 to also pivot when the arm 64 is pivoted.
  • the main joint former 44 is followed by a joint filling device 90 indicated in FIGS. 1 and 2.
  • This is rigidly connected to the concrete ceiling paver frame 24, for example via a frame part 92 which adjoins the horizontal frame part 84.
  • the joint filling device 90 is connected via a feed hose 94 joint filling material is supplied from a storage container, not shown.
  • This material is filled into the longitudinal joint 96 formed behind the main joint former 44 via nozzles of the joint filling device, which are not shown in detail.
  • the joint filling material can be support material, preferably sand or bentonite. You can also foam out the joint.
  • the joint 96 can also be wetted with a release agent which prevents the joint side walls from sticking together. A wax-like release agent can be used for this.
