Definitions

  • the invention relates to a device for preparing concrete surfaces for gluing tab reinforcements, in particular in the area of the hollow box interior of bridge structures.
  • the invention is therefore based on the object to provide a device for preparing concrete surfaces for gluing tab reinforcements, in particular in the area of the hollow box interiors of bridge structures, by means of which the production of the channel-shaped recesses is possible with less negative influence on the remaining concrete body in a simple manner.
  • the device comprises a carriage which can be moved along the concrete surface to be prepared, a cutting body by means of which the concrete surface can be milled, a drive shaft which is rotatable on the carriage and on which the cutting body is mounted centrally and in a rotationally fixed manner Drive motor, by means of which the drive shaft is rotatable and which is mounted on the chassis, and has a suction device, by means of which particles etc. detached from the cutting body can be discharged.
  • the rotating cutting body precisely delimitable recesses can be created within the concrete body, whereby an impact or impact load on the framework of the remaining concrete body is effectively avoided.
  • the trough-shaped recess can be designed so precisely that the tab reinforcement can be brought into large-area contact with the concrete body.
  • a rail guide which can be installed in the hollow box interior along the direction of extension of a bracket reinforcement and along which the carriage can be moved back and forth, an exactly straight alignment of the channel-shaped recess can be ensured even with particularly long bracket reinforcements, with a further leveling out the depth of the groove-shaped recess to be created can be achieved.
  • a feed bracket can be detachably attached to the chassis.
  • a detachable attachment of the feed bracket is advisable, since access to the hollow box interior mentioned is only possible through relatively small manholes. Through these manholes, any machines and devices to be used in the hollow box interiors must also be introduced into the hollow box interiors.
  • a particularly advantageous embodiment for the cutting body is obtained if the latter is formed from a plurality of cutting blades, each cutting blade being mounted on the drive shaft in a rotationally fixed manner. If the said cutting blades are spaced apart from one another on the drive shaft, the gaps formed between the cutting blades can be used to cool the cutting body, which results in a considerable extension of the service life of the cutting body.
  • a fan and a motor driving the suction device are advantageously arranged on a holding plate, the holding plate sitting above the actual chassis. To insert the device into the hollow box interiors mentioned, it is advantageous if the fan and motor, together with the holding plate, can be folded down or removed from the undercarriage, if necessary.
  • the cutting body is covered by a cover hood.
  • the fan of the suction device can be connected to the cover by means of a hose, the cover having a suction opening which is arranged in such a way that air sucked in through it is guided through the cavities formed between the cutting blades. This results in continuous and effective cooling the cutting blades, whereby the cooling flow can also be used as a transport medium for the particles and components detached from the concrete body.
  • a device shown in FIGS. 1 to 3 for the preparation of concrete surfaces for the application of tab reinforcements in the area of the hollow box interior of bridge structures is designed as a device that can be moved by hand.
  • a rail guide 1 is provided, which can be installed in the interior of the hollow box along the surface of the concrete part to be treated or along the strap reinforcement to be installed.
  • a chassis 2 of the movable device movable back and forth is mounted on the chassis 2, a drive shaft 3 is mounted by means of a bearing, not shown.
  • the drive shaft 3 is driven by a drive motor 5 via a gear member 4 (not shown in detail).
  • the drive motor 5 and the transmission element 4 are also attached to the chassis 2.
  • a cutting body 6 is mounted concentrically and non-rotatably on the drive shaft 3.
  • the cutting body 6 consists of a plurality of cutting blades 7 which are attached to the drive shaft 3 in a rotationally fixed manner at the same distance from one another. Spacers 8 are provided between the cutting blades in order to keep the distance between the cutting blades 7 constant. This results in cavities or spaces 9 between the cutting blades.
  • the drive shaft 3 is adjustably mounted on the chassis 2 in the vertical direction. This results in a depth T of the channel-shaped recess 10 to be milled into the concrete body, which can be set as desired.
  • the drive shaft 3 and thus the cutting body 6 are adjusted in the vertical direction by means of a height adjustment device 11.
  • the cutting body 6 is covered in a wide area by means of a covering hood 12, the covering hood 12 advantageously reaching up to the surface of the concrete body, so that a loosening of loosened concrete parts and particles is reliably excluded.
  • the cover 12 is by means of one in the direction of travel of the device at the rear section of the cover 12 connected to this hose 13 connected to a fan 14 which is operated by a motor 15.
  • This consisting of fan 14 and motor 15 suction device 14, 15 is mounted on a holding plate 16. With this holding plate 16, fan 14 and motor 15 can be dismantled from the rest of the device in order to reduce its dimensions so that it can be introduced into the interior of the hollow box through the manholes mentioned above.
  • a suction opening is formed so that the air sucked through it, by means of which the material detached from the concrete body is transported away, is at least partially guided through the spaces 9 formed between the cutting blades 7 of the cutting body 6. In this way, a very advantageous cooling effect is achieved, by means of which the service life of the cutting body 6 is considerably extended.
  • a feed bracket 17 can be detachably attached to its chassis 2, by means of which the device can be moved easily.
  • the detachability of the feed bracket 17 is also due to the fact that the device or its individual parts must be inserted into the hollow box interior.
