Definitions

  • the invention relates to a movable device for setting and aligning supports in grid dimensions on a floor when creating an installation floor and furthermore shows a method for setting and aligning supports in grid dimensions on a floor.
  • Such installation floors are used in offices, in data centers, in administration buildings, in clinics, etc. They serve to arrange the walkable floor comparatively higher and in this way to create a space between the floor of the bare ceiling, in which lines and ducts can be accommodated, which are and remain comparatively easily accessible and, in so far, can also be adapted to changing conditions .
  • the installation floor has a large number of floor plates, which are supported side by side and row by row on supports in the intended grid dimension, the supports being supported on the floor or the raw ceiling.
  • a device of the type described above which has a base frame arranged on wheels, which can be designed to be movable manually.
  • setting marks are used which have the task of positioning the device relative to the setting marks.
  • the device is equipped with a feeler device, which decreases the grid size from the setting marks and, in conjunction with the mutual spacing of the supports on the device, defines the grid size.
  • the device may have a carriage to move an adhesive dispensing station therewith. It is a movement device for gripping, transporting according to the grid and setting down one support each in adhesive provided, the support being handled in the form of a strand.
  • a movement device for adjusting the height of the support is essentially formed by a chain saw with which the height of the support is sawn off the strand.
  • the device is leveled using hydraulic cylinders as a function of a laser beam that represents a horizontal plane.
  • a disadvantage of this known device is that a whole series of jobs still have to be carried out by hand. So the set marks have to be glued on by hand. The setting marks must be measured by hand; they determine the grid dimension. Furthermore, the dispensing of the adhesive must be controlled accordingly, which requires manual intervention. First, base elements of relatively low height are used as supports, so that it is additionally necessary to manually apply extension pieces of the same size if a significant free space is to be achieved between the bare ceiling and the installation floor.
  • supports which are essentially formed in two parts.
  • the lower part has a base plate which is supported on the floor and to which a pipe section is welded.
  • the associated upper part has a support plate for the base plate forming the installation floor, to which a threaded shaft is welded, to which a nut is assigned and which can be slidably inserted into the pipe section of the lower part.
  • the installation floor is now created in such a way that the bottom plate of the lower part of the support is coated with an adhesive and glued to the floor.
  • the desired height is set and leveled.
  • a number of supports are arranged at a distance from the intended grid dimension along a room edge.
  • the first floor plate of the installation floor is then assembled by gluing the remaining two supports in the manner described and adjusting their height.
  • the adjacent base plate in the row can be placed on three supports that have already been glued, and the fourth support is glued and adjusted in height.
  • Each support is provided with a fixing adhesive in the area of the threaded shaft above the nut to secure the nut against unintentional rotation on the threaded shaft.
  • Both the glue used to glue the supports to the floor and the fixing glue have corresponding processing and curing times that must be observed.
  • the position of the support in an adhesive bed can still change undesirably if the support has not been loaded in the required manner when inserted into the adhesive bed and has been pressed into the adhesive bed.
  • the adhesive is also subject to shrinkage during the curing period, which falsifies the set height.
  • the height of the four supports, on which a base plate is located is of particular importance. If the prescribed tolerance limits are exceeded, tilting movements and rattling noises occur when the installation floor is walked on because the individual floor panels of the installation floor are often provided with a metal frame, which then hits the support plates of the supports when loaded.
  • the supports While in the first row of floors laid along a room wall, the supports are glued in the direction of the room wall in the intended grid dimension, the space dimension is undershot in the direction transverse to the wall in such a way that the supports adjacent to the wall are completely underneath the two abutting corners of two floor panels reach. In contrast, the remaining supports are glued so that there are always four corners of adjacent floor panels on one support.
  • the invention has for its object to develop a device of the type described above so that a significant increase in performance can be achieved.
  • the base frame is provided with a movement drive, that the movement drive of the base frame is controlled via the feeler device, and that a control unit is provided for triggering and coordinating the movements and the adhesive task.
  • a control unit is provided for triggering and coordinating the movements and the adhesive task.
  • the various movements are coordinated and triggered via a control unit, as is the adhesive dispensing.
  • the machine also improves compliance with the tolerances, since compliance with the grid dimension depends only on the accuracy of the starting line, not on the repeated repetition of setting marks.
  • the use of the device leads to an increase in assembly performance combined with a reduction in the physical strain on the fitter.
  • the support can be deployed and adjusted very quickly. A cycle time of approx. 36 sec / support appears possible, which corresponds to 5 times the performance of an average mechanic by hand. Due to the mechanical handling of the supports when lowering and aligning, it is advantageously possible to press the supports into the adhesive bed with a defined contact pressure until at least a part of the support penetrates the adhesive bed and comes into contact with the surface of the floor. Only then is the height of the support adjusted. However, this ensures that the support no longer changes its set height during the processing time and the curing of the adhesive.
  • the drive of the base frame suitably consists of an electric motor.
  • the base frame itself can be moved on wheels. Three wheels are expediently provided in order to ensure that the device can be easily steered, namely on conditionally uneven ground, e.g. B. across cables or even in confined spaces.
  • the keying device reproduces the grid dimension anew with each line by repeatedly decreasing it on the previous line. By recognizing the gap between two adjacent floor plates, the device is stopped, the drive is decoupled and the device is braked so that the grid dimension is maintained. A portion of adhesive is then dispensed into the intended grid point and a support is removed from a magazine via a gripping device and lowered and pressed into the adhesive bed at the provided grid point.
  • the gripping device continues to hold the support so that a device for adjusting the height of the support can now be activated.
  • This is a rotary drive that engages the support plate, that is, the upper part of the support, and rotates it relative to the held nut until the desired height is set with the required tolerance.
  • the device When using this device, the first floor row along a room wall must still be created by hand. As soon as this floor row has been erected, however, the device can be used to drive along the room-side edge of this floor row and to place the supports. With the step-by-step approach along a floor row, the floor slabs can be immediately placed on the supports, since the set height no longer changes due to the weight of the floor slabs, although the curing process of the adhesive only takes place subsequently. It is important that the device carries out the application of the adhesive, the placement of the support and the height adjustment in any case. If necessary, further work steps can also be carried out by corresponding stations of the device in order to ensure uniformity. On the other hand, such work, such as cleaning the point at which the adhesive is applied and applying a fixing adhesive to the threaded shaft of the Support, if necessary, also be carried out manually to keep the structure and mode of operation of the device simple.
  • the drive of the base frame can have a clutch and a brake; the pushbutton device is provided with a light barrier for taking the grid size from an already installed floor row or a reference row.
  • the drive can also take place in two stages, that is to say at two speeds, in order on the one hand to be able to drive comparatively quickly over the essential distance between two grid points, while on the other hand the exact approach to the grid point takes place at a slower speed.
  • Two light barriers are then expediently provided on the device, the first light barrier in the direction of travel merely triggering the switch from the fast speed to the slow speed and the second light barrier braking and switching off the drive.
  • the dispensing station for adhesive can have a storage container, a line and a valve arranged in the line, which is connected to the control unit. In this way, the portion of adhesive at each grid point can be reliably maintained due to the opening time of the valve. It is not necessary that the dispensing of the adhesive and the erection of the support coincide in one grid point each time the device is held. It is advantageously possible to provide the end of the line from which the adhesive is dispensed and the device for placing the support offset by the grid dimension on the device, so that both Processes can take place simultaneously or overlapping one another with a further increase in performance.
  • the device for gripping, transporting and depositing one support each has a piston / cylinder unit.
  • a support gripper is arranged on the piston rod of the piston / cylinder unit.
  • the cylinder of the piston / cylinder unit can be moved horizontally in the working direction via a slide and in the opposite direction on a portal on the base frame.
  • a magazine is provided in which, for. B. a series of supports is set up.
  • This magazine can be designed as an interchangeable magazine, that is, it can be exchanged with the set supports.
  • the device for gripping is also equipped with a light barrier or another detection device which detects the respective position of the supports in the magazine and controls the gripper so that it grips the respective support in the correct place.
  • the carriage is then moved with the piston / cylinder unit to the point of sale and the support is lowered by extending the piston rod, a defined, adjustable final pressure being able to be established in order to press the support into the adhesive bed.
  • the support gripper can have two gripping jaws, each pivotable by approximately 90 ° relative to one another, for gripping the support, including an adjusting nut arranged there.
  • the gripping jaws which can be pivoted relative to one another by approximately 90 °, are required insofar as the open jaw Support gripper must pass a set support and the supports in the magazine sideways, since the device is steered and driven along a straight line.
  • This problem can also be solved in other ways, e.g. B. in that the support gripper is designed to be movable transversely to the working direction.
  • the movement device for adjusting the height of the support has a vertically movable rotary drive mounted on a piston / cylinder unit. This rotary drive engages on the support plate of the support, while the lower part of the support together with the adjusting nut is held by the gripper jaws.
  • the rotary drive is controlled by a balance device, which is based on the principle of a spirit level and on the one hand rests on floor slabs of an already installed floor row and on the other hand uses a support point on the slide of the rotary drive. The rotary drive is now activated until the balance device determines the required accuracy of the height adjustment and then ends the rotary drive.
  • a nozzle for the targeted blowing out of compressed air can also be provided on the base frame before the adhesive is applied. In this way, the footprint on the floor is cleaned so that the adhesive is then applied to this cleaned location and so far there is no separation layer between the adhesive and the floor. It is also possible to additionally provide the device with a device which allows fixing adhesive to be applied to the threaded shaft of the upper part of the support.
  • the method for setting and aligning supports in grid dimensions on a floor when creating an installation floor provides that on the floor in Apply a column with adhesive to the respective grid point and adjust the height of the column with a nut. It is characterized according to the invention in that the support is pressed mechanically after lowering into the adhesive, and in that the support is held on its mother and the upper support part is rotated relative thereto until the height of the support is adjusted. Due to the mechanical pressing, a higher contact pressure than with manual work and above all a reproducibly identical contact pressure can be brought to bear on the different supports. The higher contact pressure also leads to improved crosslinking of the adhesive. Furthermore, the nut is held in place and the upper part of the support is rotated, which has the advantage that the lower part of the support is thereby kept fixed.
  • the support is particularly advantageous for the support to be pressed into the adhesive with a force corresponding to the weight of a base plate. This ensures that, on the one hand, the support sinks sufficiently deep into the adhesive bed and, on the other hand, the subsequent placement of the base plates cannot lead to a further change in the height of the support.
  • the floor can be cleaned at every grid point before the adhesive is applied by blowing out compressed air.
  • the entire control device can be designed using electronic components.
  • a drive element compressed air is expediently provided so that the two piston / cylinder units are actuated pneumatically.
  • Such a source of compressed air can either be arranged stationary and connected to the device via a movable line.
  • An electric motor is expediently used as the drive,
