Definitions

  • the invention relates to a method of the type specified in the preamble of patent claim 1 and to a device which is expedient for carrying out the method according to the preamble of patent claim 5 and a pavement paver according to the preamble of claim 19.
  • a transversely movable carriage with a vertically adjustable plate is mounted in a movable chassis.
  • Pneumatic cylinder-piston units are attached to the plate, the pistons of which are connected to impact hammers which represent working elements.
  • Each working element is lifted pneumatically from the pavement and, when a changeover point is reached, pneumatically accelerated downwards and hammered onto the pavement. If the working element reaches a certain depth, it remains below. If the depth of penetration is too small, the working element is raised again pneumatically and accelerated downwards again when the changeover point is reached.
  • the impact force is limited by the possible acceleration and the mass of the working element including the piston rod and the piston.
  • the impact frequency results from the mass, the pneumatic pressure, the height adjustment of the working element and mainly from the elasticity and / or the hardness of the road surface and is variable.
  • the working element is accelerated by the pneumatic pressure pulse, when it is opened it is pneumatic pressure is no longer effective because the piston is relieved of pressure beforehand. Since the energy stored by the working element for each stroke is limited, it must be brought into action as suddenly as possible in order to have an effect. Hammering, however, leads to grain fragmentation and the removal of parts of the pavement, which is desirable when leveling, but is undesirable for roughening. The roughening effect is unsatisfactory because the impact and the removal result in a flat but in turn relatively smooth surface of the pavement.
  • the known method and the device used for it are only suitable to a limited extent for roughening polished carriageways (track grooves with the risk of aquaplaning, smeared braking or acceleration zones, and the like.)
  • roller bodies subjected to load are rolled over the road surface in order to roughen them by cracking.
  • the roller bodies can be subjected to vibration in addition to the load.
  • the device known for performing the method is a self-propelled vehicle, on the vehicle frame of which the relatively narrow roller bodies are suspended. The time and energy required for roughening are high. A uniform roughening effect can only be achieved with constant, great care by the driver.
  • the vehicle itself is an expensive special vehicle.
  • the invention has for its object to provide a method of the type mentioned and a suitable device for carrying out the method and a pavement paver with which road surfaces are roughened better than before with little and well used energy.
  • the object is achieved according to the invention with the method according to the characterizing part of claim 1 and with a device according to the characterizing part of claim 5 and with a paver according to claim 19.
  • the device As a roughening screed add-on unit, the device is an independent work unit that can be combined with virtually any towing vehicle that can provide the appropriate drive and energy supply.
  • the mass represented by the individual components is the key to gentle and intensive roughening.
  • the drives are supported upwards so that the pressure threshold forces can be fully activated via the working elements in the pavement.
  • the device is robust and structurally simple, user-friendly, universally applicable and low-wear.
  • the drives In operation, the drives are supported, as it were, against a stationary abutment, while they press the roughening elements into the road surface in a precisely predetermined manner. Compared to known and expensive special and roughening vehicles, this is an inexpensive aspect that is important in terms of transport and universal use.
  • the feared grain crushing and the removal of components do not occur in operation. It is surprisingly found that even small grains or stones are scratched with the device without breaking and remain fixed in the bond. Surprisingly, the device works with little noise and dust and above all without any noticeable vibration, which
  • the paver is expanded to a roughening machine by the attached roughening screed removal unit.
  • a normal screed however, it can be operated in the usual way. So far, it has been common to use different machines for roughening and finishing the ceiling, which is due to transport, storage and the Maintenance is expensive and time-consuming. Practically every paver can be converted by installing the appropriate roughening screed add-on unit.
  • high indentation forces can be generated for the roughening elements, so that smooth or difficult to roughen road surfaces due to their nature can be roughened uniformly in one pass and to the desired degree of roughness. Because of the frequency of the pressure threshold forces, the overlying masses approach infinity in the dynamic phase; it can no longer be raised by the reaction forces of the pressure threshold forces.
  • the absolute value of the pressure threshold forces can be greater than the static weight of the mass; the frequency ensures in the dynamic phase that the mass and therefore the device does not start to oscillate. This leads to a low-noise, practically vibration-free process sequence and to a precisely adjustable roughening.
  • pressure threshold values of different strengths can be set precisely and reproducibly. Generating the pressure swelling forces hydraulically has the advantage of a precisely determined course of force over time. The force curve is matched to an optimal roughening effect and the type of pavement.
  • the method variant according to claim 4 is also important because the phase shift makes the method sequence quiet.
  • the quality of the roughening is of high quality, since neighboring roughening elements do not act simultaneously and do not influence one another.
  • the embodiment according to claim 6 is adjustable in the working width to the respective requirements and convertible even during operation.
  • a road surface paver is the ideal towing vehicle in the embodiment according to claim 7.
  • the roughening screed attachment is attached instead of the usual screed.
  • the paver provides the drive energy for the drives of the demolition unit and can be driven sufficiently slowly and precisely. A separate towing vehicle is not needed.
  • the offset and arranged in rows one behind the other roughening elements allow an individual adaptation to the profile of the road surface, each roughening element being machined in a relatively small area and subject to low loads. This enables the roughening elements to have a long service life.
  • Hydraulic working cylinders allow a precisely reproducible adjustment of the value of the course of the pressure threshold forces.
  • Each roughening element works at the just correct height specified by the road surface profile.
  • the usual hydraulic basic pressure keeps the roughening elements in contact with the road surface between the effects of the pressure threshold forces. Even very powerful working cylinders can be accommodated in a small space.
  • the control and power supply are technically simple.
  • the embodiment according to claim 11 is advantageous in terms of manufacture, maintenance and repair.
  • the tool insert can be selected for the respective type of pavement.
  • the strip-shaped tool insert can be in one piece or in several parts or have several pyramid-shaped teeth.
  • the roughening elements are guided and supported cleanly when working.
  • the joint enables each roughening element to adapt to the road surface profile so that the tool insert works evenly.
  • the joint also excludes oblique forces on the working cylinder.
  • the transverse movement generated by the transverse drive leads to serpentine grooves during the movement of the device, which results in a uniform roughening effect for different directions of travel.
  • the groove network becomes very dense due to the serpentine shape.
  • the serpentine shape is also advantageous in terms of driving safety (no guiding effect for vehicle tires) and driving comfort (no roaring noises).
  • the embodiments according to claim 17 and claim 18 are also important because the environment is protected from the dust and dirt that is inevitably generated when roughening, and because the vehicle driver can also work unhindered by the dust and concentrate on his work.
  • the transverse drive which is used for the serpentine grooves, can be accommodated in a pavement paver particularly expediently according to claim 20.
  • a stroke of approx.12.5mm on each side is sufficient.
  • the transverse elasticity of the cantilevers can be used without any structural modification.
  • a device V for roughening a road surface (concrete or bituminous road surface) is designed as a roughening screed add-on unit A and provided with fastening elements E in order, for example, to be connected to arms B, to be pulled by a tractor vehicle over the road surface to be roughened.
  • the towing vehicle can be of any type. Since the device V, which can be designed with a fixed width, so to speak in one piece, is designed as an extending screed with a central screed main part H and two laterally extendable and retractable screed add-on parts Z as shown in FIGS. 1 and 2, the roughening screed attachment unit A expediently Instead of a conventional screed attached to a road surface paver D as a towing vehicle S (Fig. 5).
  • the device V has a plurality of roughening elements W arranged transversely to the main direction of movement F in three rows, which abut the road surface from above and are pressed into the road surface by drives P.
  • the roughening elements W are individually guided vertically up and down in a carrier 3.
  • a support part sliding plate 4 or rollers 4a
  • the frame 2 is firmly seated on the frame parts 1 located above.
  • the drives P for the roughening elements W are firmly connected to the frame 2 and are coupled to the roughening elements W at least in the downward pressure direction.
  • the screed attachment parts Z are designed similarly.
  • the carrier 3 for the roughening elements W is attached to the frame 2 of each screed attachment Z.
  • the screed attachment parts Z are attached with their top parts 5 via sliding guides 6, 7 to the top part 1 of the screed main part H and can be extended laterally by means of drive devices (not shown) in order to adapt the working width to the respective requirements (FIG. 2).
  • Such screed concepts are known in paver manufacturers for the screeds used there.
  • Front and rear guide elements 8, 9 and intermediate sliding plates 10 are arranged in the carrier 2 for the roughening elements W.
  • Each roughening element W consists of a cuboid holder 11 and a tool insert 12 on the underside.
  • the drives P are hydraulic working cylinders which are connected to a control device 35, for example a rotary valve 37, see FIG.
  • a separate drive P is assigned to each roughening element W.
  • the drives P generate downward pressure threshold forces for the roughening elements W and are supported upwards on the frame 2 and on the large mass M of the device V.
  • the pressure threshold forces are generated at a frequency which is above the natural frequency of the mass M, e.g. in a range between 50 and 70 Hertz.
  • the mass M goes to infinity, so that the drives P can generate pressure-threshold forces, which in themselves can raise the device in the static phase.
  • the frequency lying above the natural frequency of the mass Pressure swelling forces ensure that the pressure swelling forces are fully introduced into the road surface by the roughening element W because the mass above acts as an upper rigid abutment and cannot be lifted.
  • the device V is moved in the direction F along the road surface. There are parallel, closely spaced grooves from a depth of up to 6mm, for example.
  • a transverse drive C periodically moves the device V back and forth at the same time (arrow Q). The overlapping of the two movements results in a serpentine groove pattern in the pavement.
  • the drive C can e.g. be a hydraulic eccentric drive that engages the device V laterally.
  • each tool insert 12 can be approximately 75 mm, the transverse distance between the tool inserts 12 is at most 150 mm.
  • the drives P can be disconnected individually from the pressure supply.
  • the drives P can expediently be switched off in groups (group Gr in FIG. 2). With a small working width, this avoids that areas overlapping in the direction of travel F work twice.
  • the tool insert 12 is releasably attached to each holder 11, for example by soldering or screwing.
  • the tool insert 12 has, for example, pyramid-shaped roughening teeth 25. At least the roughening teeth 25 consist of hard metal.

  • the device V is attached by means of fastening elements E as a roughening screed attachment A with its fastening elements E. .
