Definitions

  • Raised floors (also called “raised floors”) essentially consist of floor slabs lined up next to each other and these supporting, height-adjustable supports, which, arranged in a regular grid, rest on a bare floor (raw ceiling).
  • Such double floors are mainly used in office, administrative, industrial and commercial buildings, etc., in order to be able to lay various types of cables in the cavity under the floor slabs freely on the unfinished floor (electrical power supply lines, control and data lines, pipes for ventilation, heating, Sewage, etc.). Thanks to easy access after lifting off individual floor slabs, such installations can be changed at any time and adapted to changing needs.
  • each column is individually measured, offset and in a grid position on the bare floor Height is set; Despite the unevenness of the floor, each support must be exactly vertical above the grid point, for which purpose the support foot is lined with wedges or supports with joint arrangements are used.
  • the supports have screw threads throughout for height adjustment.
  • the adjustment is usually carried out by placing a base plate over adjacent, already set and the new support to be set and then checking the plate position using a spirit level; it is often necessary to remove and replace the heavy plates. So far, the double floor installation has been very tedious due to the heavy physical work close to the floor and only progresses slowly even with trained personnel.
  • the aim of the present invention is to significantly accelerate the progress of work compared to previously and to make work considerably easier in order to avoid severe fatigue, back and joint damage, etc.
  • the invention accordingly relates to a method for laying raised floors with floor panels lined up next to one another and to these, height-adjustable supports which are arranged in a regular grid and rest on a bare floor.
  • the method is characterized according to the invention in that leveling an auxiliary level at a distance above the bare floor over a field comprising several grid points, that prefabricated supports, each consisting of a headboard and footboard, are placed on the grid points between the auxiliary level and the raw floor, that the supports are set to the desired height at each grid point according to the respective floor clearance of the auxiliary level and the headboard and footboard are fixed to one another, and that you finally lay the floor slabs on the fixed supports.
  • the horizontal auxiliary level can be identical to the support level of the floor slabs or can be parallel to this. It can be slightly lower, for example, in which case the set and adjusted supports are supplemented by an additional, uniform support part before the base plates are placed on the head part.
  • the invention further relates to a device for performing the aforementioned method according to the invention.
  • This device is characterized by a frame determining the auxiliary level above the field, which has height-adjustable support members for positioning the device and releasable holding means for the head parts of the supports to be introduced in the field, around the head parts at points on the frame corresponding to the grid points, at the height of the Auxiliary plane aligned and protruding vertically from this, temporarily fix.
  • This device enables the supports to be inserted and set in groups, their vertical position and alignment with the grid points after the auxiliary level or the frame has been leveled for the whole group.
  • the invention relates to a prefabricated raised floor support which is particularly developed and suitable for use in the abovementioned method and with the abovementioned device (although it can also be used elsewhere). It is based on a double floor support EP-A-0 295 905 consisting of a head part and foot part, which are adjustable relative to each other for the purpose of height adjustment of the support, with fixing means for mutual fixing of the relative position between the head part and foot part.
  • a support is characterized in that the head part and the foot part are guided so as to be freely displaceable with respect to one another and are continuously adjustable in the direction of the support axis without mutual rotation.
  • the raised floor support designed in this way makes it possible (in contrast to known supports with thread adjustment), the height adjustment of several supports at the same time - and also simultaneously with the leveling of the auxiliary level.
  • a device which is intended to compensate for unevenness in the raw floor before the double floor installation.
  • the device can be moved on the bare floor and has lateral holding devices for semi-finished material strands. These strands are individually lowered to grid points on the bare floor, glued there and, after the adhesive has set, cut to a defined height using a circular saw. In this way, base elements with a defined level are formed on the bare floor. Only after such preparation and without further use of the device are the actual supports - in one piece and of uniform height - placed on the base elements. Again, they must be connected to the bases before the panels can be placed on the supports.
  • prefabricated supports consisting of head part and foot part, are introduced into the device, placed on the grid points, adjusted in height and fixed.
  • the supports are specially designed for this method and the device. This significantly speeds up and facilitates the work.
  • the double floor shown in FIG. 1 during the laying and partially already laid (for example, starting from a wall of a room) has supports 5 arranged in a regular grid and resting on the unfinished floor 1. These are strung together Base plates 6, the contacting corners of four plates each resting on a support 5. Normally, square plates with an edge length of eg 60 cm are used, but other formats are also possible; the grid in which the supports 5 are arranged is of course given by the plate format. Grid locations on the raw floor 1 that are not yet occupied are designated by 2. As indicated on the right in FIG. 1, additional supports can be placed within the grid squares on grid points 2a, for example in order to support the plates 6 in the middle in the case of high floor loads.
  • the supports 5 Since the unfinished floor 1 normally has level inaccuracies and is uneven, the supports 5 must be adjustable in height or adjustable in length. In addition, each support must stand with its longitudinal axis vertically and precisely on the grid point, even if the support is uneven. Both of the aforementioned conditions must be met so that the base plates 6 carried by the supports 5 form a horizontal, flat base surface at the desired height.
  • the supports 5 are shown in a highly simplified manner with the head part 7 and foot part 8, which are adjustable relative to one another for the purpose of height adjustment of the supports.
  • the supports 5 can be connected to one another at their upper ends by horizontal struts (not shown) which run along the plate sides and / or diagonally to the plates.
  • Intermediate layers (not shown), on which the plates 6 come to rest, can also be provided on the head part 7 of each support after the supports have been set and adjusted.
  • a field 3 which comprises a plurality of grid points 2 (see also FIG. 1), an auxiliary level 4 (FIG. 3) leveled at a distance above the bare floor 1 (the field 3 can only comprise one row or, as shown, several rows of grid points 2).
  • the altitude of the horizontal auxiliary level 4 is of course related with the target position of the base plates 6, ie the position of the auxiliary plane can be identical to the underside of the plates 6 or else deviate if, as mentioned above, an intermediate layer is placed on the supports 5 after their height adjustment.
  • the prefabricated supports 5 are then set and fixed on the grid positions 2 within the field 3 to the respective height corresponding to the (different) distance between the (uneven) raw floor 1 and the auxiliary level 4.
  • the base plates 6 are finally laid on the supports set and set in this way. The latter can either take place "field by field” immediately or later on a larger, contiguous floor area.
  • the device 10 has a frame 11, which is preferably designed as a torsion-resistant and bending-resistant lattice construction and which determines the auxiliary level 4. Height-adjustable support members 16, 16 'serve to position and level the device 10 above the field 3 in the manner described below. Furthermore, the device 10 has releasable holding means 15 (which are not shown in the present example) for the head parts 7 of the supports 5.
  • the holding means serve to temporarily fix the supports 5 - at least their head part 7 - at points on the frame 11 which correspond to the grid points 2, in such a way that the head parts 7 are aligned with the height of the auxiliary plane 4 and perpendicularly from it stand out.
  • the device 10 has four brackets 12 projecting laterally from the rectangular frame 11.
  • the brackets 12 are either set up to align the frame with adjacent supports 5 that have already been placed (top in FIG. 2), or they are provided with height-adjustable support feet 16 (bottom in FIG. 2).
  • the support feet 16 are preferably removably attached;
  • the ends of the cantilevers 12 (without support feet 16 ′) lie on the supports that have already been placed, the height of the latter is thus “removed” by the device 10.
  • the outriggers 12 can, as indicated, be provided with sleeves 13 or the like, which grip over the supports 5 serving as a reference.
  • the device 10 or the auxiliary level 4 is then leveled by adjusting the height of the support feet 16 on the other arms 12.
  • the device 10 can be provided with leveling elements 17.
  • the process can be carried out by manually adjusting the support feet (for example by means of a threaded spindle) and simultaneously observing the leveling elements 17, but it can also be automated, for example using electronic leveling means and, for example, support feet 16 which can be adjusted pneumatically or by means of a thread and stepper motor drive Leveling is by no means necessary for supports that have already been set and set to serve as a reference, rather the auxiliary level can also be leveled using a reference system spanning the entire floor area of the room (for example optically using a laser beam). Additional support feet 16 'are of course used above all at the beginning of work in a room when no reference supports 5 are available yet. Retractable and extendable wheels, castors or the like can also be provided for convenient handling and change of location of the device 10.
  • a device 10 is particularly advantageous because it means that a plurality of supports 5 (or at least their head part) are positioned jointly or simultaneously on the grid points 2 within the relevant field 3 and kept perpendicular.
  • a plurality of supports 5 or at least their head part
  • the height adjustment can to a certain extent be carried out automatically and at the same time as the leveling by shortening the introduced Reach supports.
  • "telescopically" adjustable supports as are described below, for example, are particularly useful.
  • the inserted supports can also be made after the leveling of the auxiliary level 4 by extending the (previously briefly set) supports starting from the auxiliary level 4.
  • Both conventional, thread-adjustable and telescopically adjustable supports are suitable for this type of setting, although the latter can be set more quickly and conveniently.
  • the foot part 8 of each support that comes to rest on the raw floor 1 must be fastened there. This can be done in a manner known per se, in particular by gluing.
  • the above-mentioned holding means 15 for the head part of the supports 5 on the device 10 are located at locations 2 '(FIG. 3) which correspond to the grid locations 2 of the field 3.
  • the holding means should be such that after the setting, setting and fixing of the supports 5 they release them so that the device 10 can be lifted off and positioned over a next field 3.
  • the supports can be attached to the device e.g. be mechanically, electromagnetically, pneumatically, etc. releasably held.
  • the device 10A has a lower part 61 and an upper part 65, both of which are designed as grid-like frames.
  • the lower part 61 can be aligned and leveled in the manner described, e.g. by means of support feet 16 and dragonflies 17 or the like. It has stops 62 for the foot parts 51 of supports 50, such that the foot parts 51 come to rest on the raw floor 1 via the grid points 2 when the lower part 61 is aligned laterally.
  • the upper part 65 can be placed on the lower part by means of legs 66 (only one shown) which fit in the centerings 63 on the lower part.
  • the underside of the upper part 65 determines - with the lower part 61 leveled - the auxiliary level 4.
  • electromagnets 67 are shown schematically, which are fed from a current source 68 and release all head parts simultaneously when a switch 69 is opened.
  • the device 10A works as follows: First, the lower part 61 is positioned laterally and leveled to the desired height. Then the column base parts 51 are placed on grid points 2 with the aid of the stops 62 and fixed, for example glued, to the bare floor.
  • the upper part 65 - preferably still separate from the lower part - is fitted with the support head parts and then placed on the lower part 61.
  • the shaft 53 of an upper part engages with play in a bore 52 (FIG. 9) of the associated column foot part 51. All columns then have their desired height corresponding to the distance between the auxiliary level 4 and the raw floor 1.
  • the game mentioned makes it possible for the foot part to be crooked according to the unevenness of the raw floor 1.
  • Double floor supports which are particularly suitable and designed for use with the described method and the device 10 used are shown as exemplary embodiments in FIGS. 5 to 11.
  • Such prefabricated supports each have a head part and a foot part, which are adjustable relative to one another for the purpose of height adjustment of the support.
  • the supports shown here are characterized in that their head part and foot part are guided loosely in relation to each other and can be moved continuously in the direction of the support axis without mutual rotation. Locking means are also provided on these supports in order to mutually fix the relative position between the head part and the foot part.
  • the head part 21 consists essentially of a tube section.
  • the foot part is formed by a plurality of rods 30 arranged in parallel around the support axis 29; in the present case there are six bars 30, as a minimum three such bars are required.
  • the head part 21 has a fixed ring 22 and a lower guide ring 23 on the inner tube wall. In both rings, half-bores are provided corresponding to the diameter of the rods 30, in which the rods are individually longitudinally guided along the tube wall.
  • the six clamping jaws 24 are held together loosely, for example by means of a resilient wire ring 25, and are therefore radially movable.
  • the inside of the clamping jaws 24 forms a uniform conical surface with which the corresponding conical outer surface of a clamping block 26 interacts.
  • a threaded hole of the clamping block 26 sits the shaft of an axially arranged clamping screw 28, the head of which rests on a web 27 which is welded diametrically into the pipe section 21.
  • the clamping jaws 24 and the clamping block 26 together form a wedge clamping device arranged centrally in the head part 21, which acts radially on all rods 30 and can be actuated from above by means of the clamping screw 28: In a lower position of the clamping block 26 (on the right in FIG. 5) the clamping jaws 24 are loosened and the rods 30 are longitudinally displaceable, on the other hand, when the screw 28 is tightened and the clamping block 26 is raised (left in FIG. 5), all the rods 30 are clamped.
  • the wedge clamping device described above can also be designed to be self-reinforcing under load (self-locking) by reversing the conical direction of the conical sliding surfaces (narrowing cone downwards) and then tightening the clamping block against a web 27 located below (not shown).
  • the rods 30 of the column foot part are spherical at their foot end. Each rod is articulated to a support plate 32, 33 by the spherical end being snapped into a corresponding cavity in the upper part 32 of the support plate, which is made of stretchable plastic.
  • the lower part of each support plate is formed by a metal plate 33.
  • the plastic upper parts 32 can preferably be movably connected to one another to form a ring, as can be seen in FIG. 6, right half.
  • the foot part of the support designed in this way can adapt to the slanted or uneven raw floor 1 when adjusting the support, and a secure, non-positive support support is ensured with the support axis 29 standing vertically.
  • the support surface of the column foot part (underside of the plates 33) is preferably glued to the bare floor, it being possible, for example, to use a double-sided adhesive film or an adhesive to be applied.
  • the head part 41 and the foot part 43 are essentially designed as pipe sections with the same diameter.
  • Each tube section has regularly distributed, alternating longitudinal cutouts 42 'and 44' and longitudinal tabs 42 and 44 of the same width on the circumference.
  • the tabs of one part each engage in the cutouts of the other part, as a result of which the head part 41 and foot part 43 are in turn guided telescopically to one another.
  • the interlocking areas of both parts are encompassed by a clamping bracket 46 with a clamping screw 47. After the height of the support has been adjusted, the two parts are firmly clamped together by tightening the bracket.
  • the safety or resilience can be increased by attaching fine ribs and grooves on the outside of the tabs 42 and 44 in the circumferential direction, and on the inside of the clamping bracket 46 (not shown).
  • the pipe section 43 of the foot part preferably rests on a dome-shaped foot plate 45, as a result of which oblique positions of the raw floor are compensated for.
  • Both described "telescopic supports" 20 and 40 are very useful when used with the method described above. They can be conveniently adjusted in height (lengthening or shortening) without turning a thread and then fixed without any play.
  • the design also ensures a favorable, direct flow of force when transferring the floor load from the overlying floor slabs to the unfinished floor, if one considers that the loaded floor slabs mainly due to (slight) deflection in the edge area, i.e. rest on the upper outer edge of the pipe sections 21 and 41. Since the flow of force runs essentially vertically downwards, there is practically no bending stress on the supports.
  • the foot part 51 is designed as a cast part made of concrete or the like.
  • the head part consists essentially of a threaded shaft 53 and a head plate 54.
  • a threaded sleeve 55 is riveted to the latter, into which the shaft 53 is screwed and secured by means of a lock nut.
  • the height adjustment of the support 50 in a device 10 or 10A is carried out by changing the "immersion depth" of the shaft 53 in the bore 52 of the foot part with the lock nut 56 tightened (not, for example - which must be emphasized here - by adjusting the Thread engagement of the shaft 53 in the sleeve 55).
  • the axis 59 of the head part is perpendicular to the auxiliary plane 4, and the foot part can adapt to an inclination of the bare floor 1, which is possible due to the play between the shaft and the bore.
  • the resulting relative position between the head part and foot part in the device is then fixed by the adhesive 58.
  • the further embodiment variant of a raised floor support 70 according to FIG. 10 is in turn designed especially for use in the method according to the invention and with a device 10 (or 10A), but can also be used without such a device.
  • the double floor support shown in FIG. 10 has a head part 71 and a foot part 73, these two parts being adjustable relative to one another for the purpose of adjusting the height of the support.
  • the head part 71 consists essentially of a tube provided with an external thread 77, to which a head plate 72 can be welded.
  • the tube of the head part 71 is guided telescopically on a tube 75 of the foot part and is displaceable in the direction of the support axis 79.
  • a foot plate 80 is articulated below, which will be discussed in more detail below.
  • a compression spring 74 is clamped between the head part 71 and the foot part 73, in that it rests below, for example, against a pin 87 and supported at the top against the head plate 72.
  • the effect of the spring 74 is such that when the support is not loaded, its parts 71, 73 are "pushed apart" by the compression spring, that is to say that the support has an excess height h o , as is indicated by dash-dotted lines in FIG. 10.
  • a screw stop 76 in the form of a threaded ring can then be adjusted on the thread 77 of the head part 71. At the beginning of the column assembly or setting, this is in an upper position, which is also shown in dash-dot lines in FIG. 10.
  • the support is set to a desired height h s after it has been moved on the raw floor 1. This is done in that the parts 71 and 73 are pushed against each other in the direction of the arrow P against the force of the spring 74 until the desired height is reached.
  • the illustrated support is held together with a group of further supports in a device 10 (10A) on the head part and projects vertically downward from the auxiliary plane determined by the device. The supports are then placed in groups on the bare floor 1 when leveling the device and, starting from the excess height h o , shortened to their respective desired height h s .
  • each prop can also be individually adjusted to its target height.
  • the screw stop 76 is screwed down on the thread 77 and set against the foot part 73 in order to fix the set relative position between the head part and the foot part, so that the support can later take up the floor load .
  • a flange 75a is preferably provided at the top of the tube 75, against which the threaded ring 76 comes to rest. So that the support maintains its target height as long as it is not yet loaded (by later laying on the raised floor panels), it is advisable to provide locking means that act on the force between the parts 71 and 73 when the screw stop is engaged between this and the support foot part Spring 74 to overcome or hold.
  • FIG. 11 A variant of such locking means is shown in FIG. 11: here, instead of snap springs 78, a plurality of permanent magnets 78 '(or also a closed, permanent magnetic ring) are attached to the underside of the threaded ring 76. When the stop is turned on, the ring 76 is then held magnetically on the flange, so that the support maintains its desired height despite the tensioned spring 74. With or without such locking means 78 or 78 ', it may be expedient to release the tension of the spring 74 when the desired height is set. This can e.g. just happen that the pin 87 is not stuck in the tube 75 and can be pulled out after adjustment, whereupon the spring relaxes.
  • the special design of the base plate 80 according to FIG. 10 is such that a vertical position of the support or its axis 79 is ensured even when the plate is slanted on the floor 1 in any direction (indicated by dash-dotted lines in FIG. 10).
  • Foot plate 80 and telescopic tube 75 of foot part 73 are held together by means of a screw 84 and anchor plate 86, an elastic intermediate layer 85 between the anchor plate and an inner flange of the tube 75 permitting a limited inclination of the foot plate 80 with respect to the axis 79 in any direction.
  • a ring 81 on the top of the plate 80 there are several - for example three or four - support wedges 82 which are radially displaceable on the base plate 80; the wedges 82 are preferably radially prestressed by spring means, for example compression springs 83, which are supported on the ring 81.
