Description

"Method for producing a floor slab and floor slab produced thereby"
The present invention relates to a method for producing a floor slab in a mould, in which method concrete is poured in said mould and allowed to set to form a concrete plate having an upper surface forming the upper surface of the floor slab, longitudinal beams and respectively crossbeams being provided . at least along the longitudinal and respectively the transverse edges of said concrete plate on the lower surface thereof so as to render said floor slab self-supporting in two dimensions.
Such a method is disclosed in FR-A- 2 560 621. In this known method, the longitudinal beams and the crossbeams are made of reinforced concrete poured in corresponding recesses provided in the bottom of the mould. A drawback of this known method is that the upper surface of the moulded floor slab cannot be used as such as floor surface so that in practice an additional flat finishing layer has to be applied onto the floor slabs.
As it appears from FR-A-1 302 064 it is also possible to finish the upper surface of the moulded floor slab further to a sufficiently flat surface which requires, however, additional smoothing operations.
An object of the present invention is now to provide a method which allows to produce floor slabs in a mould which have a sufficiently flat upper surface without requiring hereto additional smoothing operations. To this end, the method according to the present invention is characterized in that the upper surface of said floor slab is formed by pouring said concrete onto a bottom surface of the mould, said bottom surface defining thereby the upper surface of said floor slab.
By forming the upper surface of the floor slab against a bottom surface of the mould, the upper surface of the floor slab is automatically sufficiently flat. Moreover, it was found that in this way a smoothness can be achieved which is hard to obtain by the existing smoothing techniques.
In an advantageous embodiment of the method according to the present invention, profiles in particular of metal and/or of plastic are placed in said mould to provide said longitudinal beams and/or said crossbeams.
By making use of profiles, the production process of the two-dimensionally self-supporting floor slabs according to the invention can be simplified considerably.
In a further embodiment of the method according to the invention said longitudinal beams and said crossbeams along the longitudinal and respectively the transverse edges of said concrete plate are made of reinforced concrete. In this embodiment, at least one tube may preferably be arranged in said longitudinal beams, in particular a tube for underfloor heating.
The invention also relates to a floor plate produced in particular by applying the method according to the invention and comprising a concrete plate having an upper surface forming the upper surface of the floor slab and rendered self-supporting in two dimensions by longitudinal beams and respectively crossbeams provided at least along the longitudinal and respectively the transverse edges of said concrete plate on the lower surface thereof.
The floor slab according to the present invention is characterized in that its upper surface is formed against a bottom surface of a mould so that a flat upper surface can easily be obtained without further smoothing operations as explained hereinabove.
Further advantages and particularities of the present invention will become apparent from the following description of some particular embodiments of the floor slab and of the method for producing this floor slab according to the invention. This description is only given by way of example and is clearly not intended to limit the scope of the invention. The reference numerals relate to the annexed drawings wherein :
Figure 1 shows schematically a bottom view of a floor slab according to the invention;
Figure 2 shows a cross-section through a portion of the floor slab according to figure 1;
Figure 3 shows a cross-section through a portion of a floor slab in a variant embodiment of the embodiment according to figure 1; and
Figure 4 shows a top plan view on the reinforcement structure of the variant floor slab according to figure 3.
In these figures, the same reference numerals relate to the same or to analogous elements.
The floor slabs according to the present invention are generally destined for being mounted onto a supporting construction, which is not shown in the drawings, in order to erect a building. The supporting constructions used at present usually consist mainly of posts or columns which are mutually connected by supporting beams. These supporting structures may - A - comprise, however, also entire walls onto which the floor slabs are positioned.
In the method according to the invention for producing a floor slab, concrete is poured in a mould and allowed to set to form a concrete plate 1 having an upper surface forming the upper surface of the floor slab. At least along the longitudinal and transverse edges of this concrete plate 1, on the lower surface thereof, longitudinal beams 2, 3 and respectively transverse beams 7, 8 are provided so as to render the floor slab self-supporting in two dimensions. These beams 2, 3 and 7, 8 do not necessarily have to be located on the edge of the floor plate 1, but may be located along this edge, on a predetermined distance therefrom.
An essential feature of the method according to the present invention is that the upper surface of the floor plate 1 is formed against a bottom surface of the mould wherein the concrete for this plate 1 is poured, said bottom surface defining in this way the upper surface of the floor slab. It was found that by such a moulding process, a flat surface can be obtained,the smoothness of which is relatively difficult to obtain by the existing additional smoothing techniques.
Forming the upper surface of concrete floor elements against the bottom of a mould surface is already known per se from FR-A-2 156 434. However, these known floor elements, which are much narrower, do not have the structure of longitudinal beams and crossbeams according to the present invention and are more particularly only self-supporting in one dimension. The floor slabs of the present invention are, on the contrary, self-supporting in two dimensions. The expression "self-supporting" is used in this text to indicate that the floor slabs do not have to be supported over their entire length or width, but that a number of supports, for example at the four corners and possibly some further supports between these corners, are already sufficient. It is clear that the floor slabs according to the invention can also be positioned onto supporting beams or supporting walls.
In the floor slab shown in figures l and 2, both the longitudinal beams 2, 3 and the transverse beams 7, 8 are made of concrete containing an iron reinforcement 6. The longitudinal beams 2, 3 are preferably fixed to the transverse beams 7, 8 to achieve an additional strength.
In view of its width, the floor slab shown in figure 1 comprises on its bottom side two further longitudinal beam structures 4, 5 each composed of a so- called lattice-beam. This lattice-beam may possibly also be embedded in concrete. Of course, it is also possible to use metal and/or plastic profiles.
The use of concrete longitudinal beams 2, 3 and possibly 4, 5 offers the advantage that a tube 15 can easily be incorporated into these beams, in particular a tube 15 for underfloor heating with hot air or with a hot liquid.
In order to simplify the production process, use is made in a preferred embodiment of the invention of profiles which are placed in the mould to provide the longitudinal beams and/or the transverse beams of the floor slab. These profiles may be made of metal, in particular of iron, or of a synthetic material. An example of such a floor slab is shown in figures 3 and 4.
In the embodiment of figures 3 and 4, the longitudinal beams are formed of edge profiles 2, 3 and the further intermediate longitudinal beams of I- profiles 4, 5 of folded iron or possibly profile iron. The transverse beam structures 7, 8 consist of the same type of edge profiles as the edge profiles 2, 3.
In the corners, the edge profiles 2, 3 are fixed by means of corner elements 9 to the edge profiles 7, 8 so as to obtain a frame work. The I-profiles, on the contrary, are welded to these edge profiles 7, 8.
The edge profiles 2, 3 are connected to one another by means of traction bars 10. At the bottom of the edge profiles 2, 3, oblique reinforcement shores 11 are provided which are fixed into the concrete plate 1, more particularly onto the I-profiles 4, 5 so as to increase the rigidity of the edge profiles 2, 3.
In order to achieve a good anchoring of the edge profiles 2, 3 and 7, 8 into the concrete plate 1, reinforcement bars 12 are fixed to the top of these edge profiles and embedded in the concrete plate. Further, a reinforcement net is arranged in the concrete plate 1, which has not been indicated in figure 4 for clarity's sake. Preferably, an insulation layer 14 is applied against the bottom side of the floor plate 1, and this both in the embodiment of figures 1 and 2 and in the embodiment of figures 3 and 4.
From the description given hereinabove it will be clear that the invention is in no way limited to the embodiments described therein but that, on the contrary, many modifications can be applied thereto amongst others concerning the shape, the position and the material of the different components without leaving the scope of the present patent application.
