ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a device for adjusting the inclination of a surface for building on blocks, comprising an element for elevating the building surface, this element having a base surface and a top surface forming a support surface for the building surface.
DESCRIPTION OF RELATED ART
It is a known practice to use blocks in order to obtain raised floors. However, when raised building surfaces are formed, for example, on a terrace, these are arranged in a horizontal plane, while the underlying floor surface, for its part, is at a certain slope so as to allow rainwater and/or upkeep water, etc. to run away.
To convert this slope into a raised horizontal plane, it is a known practice to use shims which are placed under or on the block. To level the block to horizontal, shims of different thicknesses have to be placed under the base of the block. Additional shims 1 to 2 mm thick have to be placed on the top of the block to make fine adjustments according to the quality of the thickness of the slab.
However, the result obtained is not satisfactory because the positioning of these shims adopts a rather random nature and takes a great deal of time. There is also a problem in the case of repairs, because it is difficult to reposition a shim after the repair in the same position as it had before the repair.
BRIEF SUMMARY OF THE INVENTION
The object of the present invention is to overcome these problems.
By virtue of the device according to the invention, it is contrived that, with a sloping initial floor, the top of the block can be set to horizontal using a very simple system without the need to resort to inaccurate shims while at the same time making savings in labour.
Another advantage afforded by the device according to the invention is in the fact that, starting out with a horizontal floor, it is possible to create a sloping floor structure and thus produce a new sloping roof structure on an existing roof.
Thus, the device according to the present invention makes it possible to support raised slabs or floor structures or any other system placed on a sloping floor in the construction and to level it to horizontal. This device, placed on a sloping floor, can be adjusted in terms of height and the top of the device can be set to horizontal to level out slopes of up to 5%, namely 0 to 5 cm/m, and even more.
Thus, by virtue of the invention, there is the possibility of creating floors with slopes ranging to as much as 5 cm per meter, and even more. In known devices, the block is levelled to horizontal using shims under the base of the block and shims on the top of the block. Using the new adjustable system, the spacer piece is placed on the top of the block

and the adjustment to horizontal is simplified.
The radial and circular bars allow the angle to be adjusted gradually by continuous mutual rotation of the two discs.
Another significant advantage of the device consists in the fact that the slope can be altered simply by rotating the top part without the need to raise or remove the two spacer pieces and even without having to remove the block under the slab.
Yet another advantage of the device results from the fact that the block can be positioned in the direction of the slope and that the horizontality of the raised surface can thus be found immediately, thus affording an adjusting means which is both reliable and quick. By virtue of the device, the amount of levelling required is actually known directly, without this having to be found, thus affording immediate orientation.
The rules of the art demand minimum slopes of 2% or more and this makes it possible to conceive of steeper slopes for:
roofing accessible without stagnation or significant soiling under the slabwork;
technical floors in the chemical and other industries requiring a containment tank for removing dangerous liquids to collectors in the event of an accident; and
the renovation of various floors for which it is no longer necessary to reproduce a concrete floor, thus leading to a saving in materials and labour before installing the new raised floor, for example in offices, attics, cellars and old buildings.
The composition of the device depends on its use and it is made by injection moulding of blackcoloured plastic made of polypropylene or polystyrene or high-density polyethylene, or of polycarbonate or polyester with or without glass fibres, with or without fire-resistant and self-extinguishing additives and/or other synthetic materials. It may also be made by casting out of aluminium or steel and/or stainless steel.
The values of the slope are indicated in the top piece, thus making the device extremely convenient to use because all that is required is for the values shown to be read off. Furthermore, the device according to the invention can be fitted onto a flat-topped cylinder. Advantageously, the device can be clipped onto the block and the assembly does not become detached, which is extremely convenient on the building site. The two parts (upper and lower) of the device clip together and are therefore attached.
