Definitions
- the invention relates to a raised floor and a method and apparatus for installing this double floor and.
- double floor devices are often used.
- a double floor traditionally consists of panels which are placed on height-adjustable double floor supports, which are placed on the building floor or bare floor. Between the unfinished floor and the raised floor thus results in a low space in which media lines of all kinds, such as water pipes, gas pipes and electrical cables, can be installed on the shortest path, which eliminates the need for further planning of the installations.
- a double floor support which has a foot part with a base plate and a support tube standing perpendicular thereto, and a head part with a holding funnel, which supports one corner of a double bottom plate.
- the foot part and the head part are screwed together so that a desired height of the false floor support can be adjusted.
- EP 0 309 399 A1 proposes a double bottom support with a tiltable support plate which has a recessed spherical inner part which can be clamped after setting the inclination between a spherical ring plate connected to the foot part and a spherical pressure ring plate.
- FIG. 1 Another double bottom support known from EP0479720A1 is shown in FIG.
- This double bottom support comprises a foot part 220 with a base plate 221, which is connected via a connecting device 223 with a perpendicular to the base plate 221 aligned footer tube 222 elastically.
- the footer tube 222 can thus be inclined at a certain angle against the base plate 221 to compensate for unevenness of the soil.
- a base 310 is provided below the base plate 221.
- a head part tube 212 of a top plate 211 provided with a head portion 210 is telescopically inserted.
- the head part 210 supported by a spring 230 is displaceable against the foot part 220 until a screw stop 240 connected to the head part tube 212 strikes the foot part tube 222.
- the screw stop 240 is held by a thread and adjustable to a desired height.
- the well-known laying of the raw soil is gradual, bottom plate to bottom plate. That is, when laying the double floor sequentially raised floor supports are set and adjusted and floor panels then placed. After placing a double bottom plate, this is measured with a spirit level and adjusted the double bottom support. In this way, the double floor is gradually expanded, with the individual steps of laying a double bottom plate and the adjustment of a double bottom support repeat alternately. Overall, a high installation effort results.
- the double bottom plates are typically removed after the construction of the double floor, so that the corresponding artisans media lines, for example, electrical cables, inserted or can be placed on the unfinished floor. After inserting the media lines, the double bottom plates are placed back on the double bottom supports, often readjustments are necessary. From EP 0 479 720 AI a method for laying raised floors with juxtaposed floor panels and these supporting, height-adjustable double floor supports is also known, which are placed in a regular grid on the bare soil.
- JP 2002089022 proposes mounting a beam formed from two rail elements on the basis of double floor supports.
- the double floor supports each comprise a solid head piece, which is vertically displaceable by means of a nut along a threaded rod of a foot piece and by means of screws with rail elements applied thereto on both sides.
- the present invention is therefore based on the object to provide an improved raised floor and to provide a method and apparatus for installing the false floor, with which the input described deficiencies are avoided.
- a method which allows to install a raised floor with little effort and regardless of unevenness of the raw floor quickly and accurately.
- simple designed double floor supports should be used. On an adjustment of the double floor supports should be possible omitted.
- the raised floor should be precise and inexpensive to implement and immune to shock and vibration, so that readjustments omitted.
- the raised floor should be able to be set up quickly and dismantled again.
- the replacement of the double floor possibly with the realization of a change in height, should be feasible within a very short time with minimal effort.
- the method and the device serve to install a false floor above a raw floor.
- the raised floor preferably comprises in a regular grid on the subfloor raised double bottom columns on which juxtaposed bottom plates are arranged, wherein a double bottom support preferably supports the oppositely directed corners of four floor panels.
- mounting positions for the double floor supports are determined and the double floor supports to be installed are correspondingly positioned.
- a mounting plane lying at a mounting height is preferably determined at least partially by means of laser devices.
- the double floor supports to be installed are then guided against the mounting plane until the double bottom supports, possibly the lower end thereof, or optionally at least one already placed on the double floor supports bottom plate is at least approximately at the mounting height.
- the double floor supports are each held in the associated base until it has solidified.
- the floor slabs are not already connected to the double floor supports, they are placed on the double floor supports after solidification of the base.
- double floor supports are all at the same height in a horizontal mounting plane, the adjustment of the same eliminates. It can thus be used simply configured double floor supports that consist of a hollow cylindrical or rectangular tube in the simplest embodiment. One end of the tube forms the foot part and the other end forms the head part of the double bottom support. If the diameter of the pipe is sufficiently large and the floor supports are precisely positioned, the corners of four floor slabs can be laid down on the pipe.
- the false floor support may also have a foot part with such a tube and a head part, for example a round or square plate. Preferably identical double bottom supports made of metal or plastic are used.
- the double floor support can be configured in one or more parts.
- a double bottom support can be used, the foot part is inserted into a socket, after which a matching head part is placed, for example, to adjust the height of the double bottom.
- the double floor can be completely degraded and rebuilt in a very short time.
- the raised floor can be removed to the remaining feet, after which the equipment intended for the renovation can be moved into the room.
- the double floor supports can be made, for example, from a sheet metal with a round or polygonal cross-section. For example, a sheet is cut out and divided into four parts, which are gradually bent 90 ° to each other.
- the foot part is preferably provided with anchoring elements which are cut out of the metal sheet and bent outwards or inwards.
- the method according to the invention can be carried out in different variants preferred by the user, whereby individual method steps are also interchangeable.
- the mounting positions for the false floor supports can be determined sequentially or in groups.
- the pedestals can be made sequentially or in groups.
- the single or multi-part double floor supports can also be used sequentially or in groups in the base.
- Several, preferably four double bottom supports may already be connected to the bottom plates, so that these together with the bottom plates be positioned.
- the mounting plane can therefore also be chosen such that it lies at the level of the plane within which the installed floor panels are located. In this way, the bottom plates can be aligned at the top edge of the mounting plane.
- the base material provided to form the pedestals is preferably filled into a mold which determines the later shape of the pedestal and prevents pedestal material from escaping upon insertion of the false floor pedestals.
- the shaped piece for example a conically extending, thin-walled piece of pipe, is preferably made of plastic or sheet metal. The conical shape allows the fittings to be stacked and released after consolidation of the pedestals and reused. Furthermore, a reinforcement made of metal or plastic can be provided.
- the base material provided for forming the pedestals may each be filled into a preferably flexible container, such as a bag or a bellows, provided on the foot part of each double bottom support.
- the container connects to the foot part, so that the base material can be filled through the double bottom support into the container.
- the filling of the base material can be done immediately prior to installation of the double floor supports or the floor panels so that it can evaluate within a few minutes without an accelerator is supplied.
- an accelerator may be supplied if, for example, the base material has already been introduced earlier into the container.
- the base material provided for forming the pedestals is, for example, a concrete mix, a screed concrete, a cement mix or a mortar, which is so composed and applied that it solidifies only after a period of time within which the false floor supports are used. It is also possible the addition of funds or energy, such as heating of the base to accelerate the solidification.
- the materials mentioned have the advantage that they quickly combine with the raw soil and solidify.
- the method according to the invention makes it possible to place all double floor supports in groups and to hold them until the bases are solidified.
- the dimensions of the base are preferably selected uniformly and in such a way that even the double bottom support located at the lowest mounting position can be inserted into the base with the minimum required penetration depth. If the subfloor is largely flat, smaller sockets can be provided which ensure the secure holding of the false floor supports at the same height. By examining or measuring the raw soil, it is thus possible to optimize the material consumption.
- an installation device with a holder which in a
- Device level forms a device grid corresponding to the mounting grid with at least two or more device positions at which the
- Double floor supports can be fixed.
- the holder preferably has a frame structure with longitudinal and transverse struts, which lie in a device plane.
- the base is provided with not yet solidified base material before positioning the double floor supports or after positioning the false floor support. Particularly advantageous is the production of the base only after the positioning of the double floor supports. This eliminates the need to identify mounting positions on the unfinished floor where the pedestals must be previously installed.
- the mounting positions are determined by the orientation of the false floor supports preferably in a grid with a grid spacing of 60 cm. After the preferably vertical lowering of the false floor supports, the positions for the base are determined. These can now be constructed in a simple manner by a respective fitting is provided at the positions of the double floor supports. This is particularly easy to achieve if the fitting is coupled to the false floor support and, after the positioning of the false floor support, is driven together with it against the unfinished floor.
- the releasable connection or coupling of the fitting with the double bottom support is preferably carried out on the basis of at least one clamping element, which is additionally inserted or formed on the double bottom support or on the fitting.
- the Fitting and the at least one clamping element are preferably, as the double bottom support, also formed from a piece of sheet metal.
- the displacement of the double floor supports in the mounting positions can be done in two different ways.
- the holder is moved over a calculated distance. If the holder of several supports, each with a same drive device, such as a spindle gear, held, it is sufficient to operate each drive device in the same way, so that the holder is always moved parallel to the reference plane aligned over the desired distance.
- the holder can preferably be moved parallel to the reference plane until a lower mounting reference plane is reached.
- optical sensors are provided on the holder, which can detect the light of a laser system in the reference plane and / or the mounting reference plane. Signals from these sensors allow a control system to adjust the fixture in the reference plane and / or the mounting reference plane or at a certain distance parallel thereto.
- the holder is supported on at least three, preferably four, lifting devices and moved vertically by means of these lifting devices.
- the holder is e.g. held by supports on which
- spindle Drive devices such as electric motors are arranged, which drive a spindle.
- the spindle engages in a bearing block connected to the holder, which is displaced vertically upwards or downwards when the spindle is rotated with the holder.
- Such spindle drives are eg supplied by maxon company (see maxonmotor.com).
- maxonmotor.com There are also any other preferably controllable lift devices, hydraulic and pneumatic
- Lifting devices used, which allow to move the bracket vertically.
- the lift devices and / or the drive devices are preferably detached after installation from the holder and used for use in another holder, so that these devices need not be provided multiple times.

- the double floor supports 2 are now each held in the associated base 23 until it has solidified sufficiently, after which the holder 99 is removed. Finally, the bottom plates 1 are placed.
- the double bottom supports 2, which are preferably made of metal or plastic, can be designed simply and, in the embodiment shown, have a tubular foot part 22 and a head part 21 in the form of a top plate.
- the double bottom support 2 requires no adjustment device. Only in preference
- Embodiments two-part, adjustable or adjustable double bottom supports 2 are provided.
- the length or height of the double floor supports 2 corresponds to the difference of the height h M of the at least one mounting plane E M to the height h DB of the double floor 10 (height h DB measured at the bottom of the floor panels 1).
- the height of the double bottom 10 can be determined. This is particularly advantageous if a new raised floor 10 at a different height h DB is to be installed during a renovation or renovation.
- FIG. 2 shows that the false bottom supports 2 are set with the precision of the laser device 91 and kept stable in the sockets 23.
- a top plate 21 is therefore not necessary in principle.
- the corners of the floor panels 1 can also be securely mounted on a pipe of appropriate diameter. A shift of the double floor supports 2 even when massive shocks occur is practically impossible, which is why inventive raised floor 10 can be used particularly advantageously in areas where earthquakes are expected.

- the beam 991 is lowered in the manner described above until the bottoms of the false floor supports 2A, 2B, 2C are at the mounting positions at the level of the mounting plane E M.
- the fittings 300 are pushed down until they rest on the unfinished floor 3, as shown in Figures IIa and IIb.
- the cross section of the false floor supports 2A, 2B, 2C is smaller than the cross section of the smaller opening of the tapered fitting 300, and therefore space remains between the outside of the false floor supports 2A, 2B, 2C and the inside of the fitting 300 to base material 2300, for example, a concrete mix to fill.
- the Double floor supports 2A, 2B, 2C preferably have openings which allow the liquid base material to penetrate into the false floor supports 2A, 2B, 2C.
- Figure IIa shows the filling of base material 2300 in the molding 300A, while the double bottom support 2A is still held by the bar-shaped element 991 of the holder 99.
- Figure IIb shows a double bottom support 2 with anchoring elements 29, which can hold the double bottom support 2 in the base 23 safely. Further, the double bottom support 2 has parallel and close to the edges extending beads, which give the double bottom support 2 increased strength.
- Figure 11c shows the false bottom support 2B held in the solidified base 23B after removal of the beam-shaped element 991.
- the holder 99 can be gradually removed after the positioning of the first bar 991 in the reference plane E R and also dismantled again.
- FIG. 12 shows four double bottom supports 2A, 2B, 2C and 2D, which are preferably fixedly connected to a base plate 1 and on whose base parts 2300 filled containers 3000A, 3000D are provided. Unless the
- Double bottom supports 2A, 2B, 2C and 2D are configured tubular, the base material 2300 can be introduced through the double bottom supports 2A, 2B, 2C and 2D in the container 3000.
- base plates 1 can be positioned at the intended height, after which the base material 2300 adapts to the green floor 3 and then solidifies. In the Positioning and alignment of the bottom plates 1, the base material is thus pressed against the green floor 3 and displaced as far as necessary laterally.
- the container 3000 can be previously eliminated or left.
- a container is provided which consists of at least partially perforated material, for example a plastic film, which allows air and / or water to pass. Symbolically, it is shown that a material 2301 can also be supplied which accelerates the curing process.
- the bottom plates 1 equipped with corresponding double bottom supports 2A, 2B, 2C and 2D and containers can be aligned quickly positioned and thus mounted within a short time.
- the bottom plates 1 can be sequentially coupled with each other so that they are precisely in one plane.
