Definitions
- the invention relates to an apparatus and a method for leveling dry bedding on a floor by means of an elongate stripping element.
- Dry slabs have also been offered by the industry for years as an alternative to mortar screed.
- the advantage of dry screed is the fast processing without water and thus the immediate further processing with the topsoil. Equally important is the weight savings, statically often without concern, but particularly attractive in the rehabilitation area, where mortar screed is often not possible.
- the disadvantage is the price, which is a multiple of that for traditional mortar screed. Nevertheless, the area of dry screed used in Germany by industry and associations is currently given as approx. 5 million square meters, with a strong upward trend. Of the area mentioned about 80% are laid with dry bed.
- the dry bed is a granulate, for example expanded clay, with a grain size of 2 to 4 mm and a specific weight of about 400 kg / m 3 . This allows a height compensation of 10 to 100 mm without compaction and up to 350 mm with compacting of the dry bed.
- a conventional apparatus for leveling dry bed on a floor is an elongated stripper in the form of a batten or the like, and the corresponding method is to handle the stripper to spread and level the dry bed.
- the procedure recommended by the industry for leveling the dry bed is as follows: The heights of the room to be treated are measured with the hose scale. Parallel to the walls, small ramparts are applied from the bed at a distance of 2 to 3 m. These ramparts are brought to the desired height from the meter break with the aid of spirit levels. representation on which are laid standards, over which then with another latte the remaining material can be deducted. Niches, corners and protrusions are pulled in by hand with a smoother.
- Installation times are given by the industry at times of 6 minutes to 18 minutes per square meter, with six minutes merely subtracting the bed. 18 minutes, on the other hand, are the estimated maximum amount of time from measuring to completion of the bed. In practice, screed installers require assembly times of around 12 minutes.
- the invention has for its object to provide an easy-to-handle device and a method for leveling of dry bed, which allow a very fast leveling of the bed with very high accuracy.
- the support device may, for example, be a multi-member cantilever arm whose members, for example two members of substantially equal length, are rotatably connected to one another and which are pivotable relative to one another in the horizontal plane.
- a two-part arm has a total length of about 3 meters and carries at the end a rotatable and manually to moving Abziehelement, which is called together with a carrier Abziehhist.
- a total area of max. 30 m 2 are processed, without having to change the device.
- the split arm allows the tapping of all contours. Heater niches and protrusions can be formed as precisely as skewed or round layouts.
- the arms can be made from lightweight and extremely stiff sandwich panels or from tubes made of aluminum or carbon fiber composite, so that despite a maximum tolerance deviation of 2 mm, a weight of about 30 kg is not exceeded.
- An alternative or additional way of producing the torsional stiffness required for accurate work is to provide struts and / or guy ropes similar to a suspension bridge that hold the support rigid and straight.
- the support device preferably has a rotatable support adapted to fix or set up the device at a desired distance from the ground.
- the holder is preferably a separate component and can be mounted according to local conditions. Ideally, a telescopic pole is stretched between the ceiling and the bare floor to which the bracket is mounted.
- measuring and adjusting devices for measuring and / or fine adjustment of the horizontal plane in which the puller is free to move.
- the holder has sensitive dragonflies and can be aligned either manually or independently by means of a laser exactly.
- the bracket can also be mounted on a tripod, on a wall or a support. The holder allows a rotation of 360 ° free standing in the room or in the worst case, mounted on the wall, of 180 °.
- Torsional stiffness requirements can be reduced by a measuring device for continuously measuring the horizontal position of the peeling element and a height adjusting device for automatically adjusting the horizontal position of the peeling element in accordance with the measured values provided by the measuring device while the peeling element is manually moved over the ground.
- a measuring device for continuously measuring the horizontal position of the peeling element and a height adjusting device for automatically adjusting the horizontal position of the peeling element in accordance with the measured values provided by the measuring device while the peeling element is manually moved over the ground.
- Suchcitehthrot is held on the support device, and od, for example, in an electrically operated spindle. The like.
- the - A - Automatically maintains the wiper blade at a constant level using electronic measuring signals, such as an integrated electronic spirit level or an ultrasonic distance meter to measure the distance from the ceiling.
- the leveling takes place electronically by means of a transmitting unit whose signals are received by the carrying device with the peeling sword.
- Sending unit and supporting device are mechanically not connected to each other in this embodiment.
- the assembly time is significantly reduced.
- leveling of the auxiliary dams and gauges has been started so far, it is already possible to install the dry bed, without any additional effort even in the hitherto problematic edge areas and niches.
- an assembly time of 1 to 2 minutes compared to the previous 12 minutes is realistic.
- the quality of the work is significantly increased because now a space of about 20 m 2 can be processed from just one point and thus an absolutely flat surface with differences of about 2 mm compared to the previous 10 mm is achieved.
- the laying time of the screed panels is also significantly reduced due to the exact subfloor, as reworking omitted. Complaints due to incorrectly introduced bed are almost impossible.
- FIGS. 1a and 1b show a schematic side view and top view of a leveling device for dry fill in a first exemplary embodiment

- FIGS. 2 a and 2 b show a side view and a top view of a leveling device for dry fill in a second exemplary embodiment
- Figure 3 is a schematic view of a leveling device in a third embodiment.
- the leveling device shown in Figures 1a and 1b has a holder 2, which can be placed on a telescopic rod 4, which is stretched vertically between the ceiling and floor of a room to be provided with dry bed for dry screed.
- the holder 2 has locking screws (not shown) for locking on the telescopic rod 4 and measuring and adjusting devices (not shown), e.g. Dragonflies and micrometer screws.
- first elongated horizontal support member 6 consisting of upper and lower support members 6a and 6b, respectively, which are parallel at a distance.
- first horizontal support member 6 is horizontally rotatably connected to one end of a second elongate horizontal support member 8 which is approximately the same length as the first support member 6.
- Abziehhist 10 is horizontally rotatably mounted, which consists of a vertical supporting and adjusting rod 12 and a horizontal Abziehelement 14.
- the second support member 8 can be pivoted about the pivot point at the junction of the first support member 6 and the second support member 8, that its end describes a circle, in Fig. 1 b with a dashed line is displayed and have a radius R1.
- the stripping member 14 passes over a smaller circle of radius R2 around the end of the second support member 8 when the stripping member 14 is rotated (a 90 ° rotated position of the stripping member 14 is shown in phantom in Fig. 1b).
- the first support member 6 can be pivoted around the telescopic rod 4, when it is free in space.
- the leveling device shown in FIGS. 2a and 2b is similar to the leveling device shown in FIGS. 1a and 1b, and components which functionally correspond to the components shown in FIGS. 1a and 1b are a holder 2 'in FIGS. 2a and 2b. a vertical rod 4 ', first support members 6'a and 6'b, a second support member 8' and a Abziehhist 10 'of a vertical support and adjustment rod 12' and a horizontal Abziehelement 14 '.
- the leveling device of FIGS. 2a and 2b is composed of tubes and connecting sleeves instead of more or less massive links.
- a third embodiment of a leveling device according to the invention is shown schematically in Figure 3, wherein the - in this case not yet leveled - bulk material 28 is indicated in this figure by wavy lines.
- This third exemplary embodiment is characterized in that the peel-off blade 10 "is not guided by a support arm and is mounted in the removal plane, but the device generally consists of two mechanically independent components, namely at least one transmission device 24 and at least one total of 38
- the transmission device 24 generates a virtual control plane 36 within the space to be leveled by means of a transmission unit 26.
- the transmitting device can be suspended in a frame in such a way that it automatically always aligns horizontally by virtue of its weight (possibly reinforced by additional weights).
- the transmitting unit 26 with respect to the transmitting device 24 is height adjustable, whereby the bulk material height is specified.
- the horizontal control plane 36 generated by the transmitting unit 26 is preferably located above the peeling plane extending parallel thereto, so that the optical signal of the laser is not absorbed by the bulk material that has not yet leveled, but parallel to the peeling level.
- the corresponding distance between the guide and Abzieariae is given and can be, for example, 20 cm.
- At the transmitting device 24 may be provided a length scale by means of which the desired bulk material height by displacement of the transmitting unit 26 is directly adjustable and readable, ie, the offset between the control plane and Abzieariae is taken into account on the scale from the outset.
- the support device 38 which can be used in this embodiment has a relatively elongated pull-off blade 10 ", on which two receiving elements 32a, 32b which are substantially vertically oriented in the position of use are mounted at a greater distance and at the same time act as handles for the support device
- Photodiodes or photodiode arrays or the like are each provided at different heights, which in each case respond to the optical signal of the transmitting device
- the user can switch to a (not shown) or by means of light-emitting diodes, possibly also by means of acoustic signals, which are given information whether he should keep the peeling sword altogether higher or lower, or whether he should correct its inclination to stay as accurate as possible within the peeling level.
- the corresponding measuring devices (as well as the transmitting device) has a relatively low energy consumption, so that they can be supplied with batteries or rechargeable batteries.
- the user would be instructed to correct the inclination of the peeling blade 38 counterclockwise so that the measuring points 34a, 34b marking the desired position would coincide with the guiding plane 36.
- actuators may additionally be provided on the support device, which can automatically perform a corresponding position correction, provided that the required correction does not exceed the amount which can be corrected by means of the actuators.
- manual and automatic correction can be provided at the same time, so that the user only has to roughly hold the carrying device in one plane based on the positional instructions, whereby finer deviations are automatically corrected.
- the periodically circulating laser signal defining the control plane is selectively recognized by the receiving elements on the one hand by means of a color filter with regard to its frequency; on the other hand, if the rotation of the laser takes place with a predetermined frequency, signal changes of the photodiodes with exactly this frequency can be detected by means of a (possibly implemented by means of a microprocessor) PLL-like circuit.
- An advantage of the embodiment described above is that no support arm construction is required, and that this embodiment is suitable for almost any room geometries, provided that a single transmitter is everywhere "visible” or receivable (otherwise several transmitters must be used). If the transmitting device operates optically by means of a laser beam, the visible light spot of the laser beam on a wall may also be useful, for example to mark the position of baseboards. Also, the position of the light spot, as it falls, for example, through a door in the next room, can be used to more accurate the heights of dumping between the individual rooms to adapt to each other. Another advantage is that, in the event that several people in a room want to level the bulk material at the same time, several Tragarmvor therapiesen can be addressed by a single transmitting device.
