Definitions

  • the invention relates to a raised floor and a method and apparatus for installing this double floor and.
  • a raised floor traditionally consists of plates, 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.
  • FIG. 1 Another from the EP0479720A1 known double bottom support is in FIG. 1 shown.
  • 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 31 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 raised floor is gradually expanded, with the Repeat individual steps of laying a double bottom plate and adjusting a double bottom support 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.
  • 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.
  • 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 to be realized 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.
  • a reference grid lying partially or completely is formed in a horizontal reference plane, whereby at a selected distance, a mounting plane lying parallel thereto, preferably lying completely within the blank, is defined.
  • at least one tool possibly driven by a machine, is displaced vertically and / or horizontally with respect to the reference grid in such a way that a recess is incorporated into the unfinished floor, the base area of which lies at least approximately at the height of the at least one mounting plane.
  • the one- or multi-part double floor supports whose dimensions correspond to the difference of the height of the at least one mounting plane and the height of the double floor, are inserted into the recesses.
  • the floor panels are placed on the double floor supports.
  • the 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. The one end of the tube forms the Foot part and the other end forms the headboard of the double floor 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.
  • the double bottom supports are made of metal or plastic.
  • the double floor support can be configured in one or more parts. Particularly advantageously, a double bottom support can be used, the foot part inserted into a recess and potted, e.g. is cemented. On the one hand, this creates a stable foundation for the false floor support. On the other hand, it is possible to set up different head parts optionally, for example, to adjust the height of the double bottom. Furthermore, the double floor can be completely degraded and rebuilt in a very short time. For a renovation of a room, the raised floor can be removed down to the remaining feet, after which the equipment intended for the renovation can be moved into the room.
  • the method according to the invention can be carried out in various variants preferred by the user on a case-by-case basis.

  • the lowest point of the raw soil is determined before the start of the work and the height of the mounting plane is chosen to be less than or equal to the height of this lowest point. Since the lowest point of the raw floor lies within the assembly level, it is not possible that another point of the raw floor can be deeper, which is why this choice of the height of the mounting plane already achieved good results.
  • the depression at the lowest point of the raw soil is preferably filled up. Only then the height of the mounting plane is selected.
