Title: Floor construction BE2021/0026 FIELD OF THE INVENTION The present invention relates generally to an insulated floor construction. BACKGROUND OF THE INVENTION Various solutions exist for constructing a floor of a building. A fairly common construction comprises a system of mutually parallel, regularly spaced horizontal support girders, which support the actual floor. The actual floor can for instance be constructed by arranging one or more layers of sleepers and/or plates, for instance of wood, on the supporting beams. The actual floor can also be constructed, for instance, by arranging metal dovetail plates on the supporting beams, on which in turn a layer of mortar is applied. Said support beams can be made of, for example, wood, concrete, metal, and they can have a specially designed profile. The present invention relates especially to a four-poster structure in which the support girders are metal and have a profile referred to as a sigma profile, because of its similarity to the Greek capital letter sigma. SUMMARY OF THE INVENTION Figure 1 schematically shows a cross-section of a support beam 10 with a sigma profile, hereinafter referred to as a sigmager for convenience. The sigmaligger can for instance be made as an extrusion profile or as a folded sheet. The sigmaligger 10 comprises a central plate-shaped body part 11, which in the use situation is oriented vertically as shown. At its top, the sigligger 10 has a support flange 12, which is substantially perpendicular to the plate-shaped body portion 11. Side flanges 13 and 14 are directed downwardly from the side edges of the support flange 12, toward the plate-shaped body portion 11 and substantially parallel thereto. . On its underside, one of said side flanges 13 has a relatively narrow, inwardly directed end face 15, substantially parallel to the support flange 12. The end face 15 has a free end edge on its side directed away from the corresponding side flange 13. Of the other side flange 14, the lower end edge 16 is connected by an oblique connecting plate 18 > BE2021/0026 connected to the top edge 17 of the plate-shaped body part 11. These plate parts 18, 14, 12, 13, 15 will be collectively referred to as head 19. The sigmaligger 10 is mirror symmetrical with respect to a virtually horizontal plane, and has on its underside a lower flange 22, a first side flange 23 with inwardly directed end face 25, a second side flange 24 and an inclined connecting plate 28, collectively referred to as foot 29. The side flanges 13, 23 with the inwardly directed end faces 15, 25, which in the figure are located on the right side of the plate-shaped body portion 11, are referred to as free side flanges, and the corresponding side (right side) of the sigmaligger 10 will be referred to as the open side while the opposite side will be referred to as the closed side. It is important for the application of the present invention that the sigliggers 10 all have the same orientation. An example of a floor construction with sigmaliggers is described in European patent 2823115. Particularly in the case of application on the ground floor, it is desirable to provide the construction with thermal insulation, which will be formed by blocks of an insulating material, for instance insulating foam. These insulation blocks are fitted between the support beams. Because the metal support beams conduct well thermally, it is also desirable to also cover the bottom flange 22 of the sigligger 10 on its underside with insulating material. It is desirable here that the insulation blocks can be placed from the top, when the support beams are in place but before the actual floor is installed. Said European patent describes to this end a combination of primary insulation profiles which are arranged around the foot of the sigmaligger, and secondary insulation profiles with a substantially rectangular cross-section resting on the primary insulation profiles. This means that two different types of insulation profiles have to be made, transported and installed. Support beams are also known which are symmetrical when mirrored in an imaginary vertical plane through their longitudinal axis, and which have a symmetrically placed horizontal flange on their underside, projecting on both sides, for instance an |-profile. In such a case it is relatively easy to fit insulating blocks, which can then rest on the top surface of the horizontal flange. However, a sigmaligger is an asymmetric beam with regard to reflection in an imaginary vertical plane. It is an object of the present invention to achieve the desired insulation properties for a sigmaligger with only a single insulation profile. More particularly, the object of the invention is to provide an insulation profile which can be placed from above and which can provide the full insulation function between and around the sigmaliggers. BRIEF DESCRIPTION OF THE DRAWINGS These and other aspects, features and advantages of the present invention will be further elucidated by the following description of one or more exemplary embodiments with reference to the drawings, in which like reference numerals designate like or similar parts, in which references "under/ above", "higher/lower", "left/right", "horizontal/vertical" etc exclusively relate to the orientation shown in the figures, and in which: figure 1 schematically shows a cross-section of a sigmaligger; Figure 2 is a schematic cross-section of an insulation profile proposed by the present invention; figures 3A, 3B, 3C illustrate the placing of the insulation profile according to the present invention; figure 4 illustrates some design details. DETAILED DESCRIPTION OF THE INVENTION Figure 2 is a schematic cross-sectional view of an example of an insulation profile 100 proposed by the present invention, and Figures 3A, 3B, 3C illustrate its installation. In particular, figures 3A, 3B, 3C show that two insulating profiles 100A and 100B always adjoin on either side of a sigmaligger 10L, and that an insulation profile 100B is always placed between a left sigmaligger 10L and a right sigmaligger 10R. It is noted that the insulation profile 100, like the beams 10, have a longitudinal direction perpendicular to the plane of the drawing, and have a constant profile in that direction. In principle it is possible to make a sigmaligger with arbitrary sizes for the mentioned parts. In practice, however, a sigmaligger is a standardized product, in which the sizes of the parts in the head are 19 and foot 29 are always the same, while the height of the plate-shaped body part 11, hereinafter also referred to as the "body", may differ. The mutual distance between the beams is in principle freely selectable, but in practice standardized center-to-center distances will be used. It is noted that the precise shape and dimensions of the insulating profile 100 will depend on the dimensions of the sigliggers, and on the intended mutual distance between the sigliggers, as will be clear to a person skilled in the art after reading the following description. The insulating profile 100 consists of a good insulating material, for instance foam. It has a substantially flat top surface 110 and a substantially flat bottom surface 120. The insulating profile 100 is designed to be fitted, from above, between two sigmage bearings, as will be discussed in more detail with reference to Figures 3A-C. The insulation profile 100 is clearly asymmetrical. A first side (in the figure the right side) 130 is profiled to mate with the closed side of a first sigmaligger, which will be referred to as right sigmaligger 10R. The opposing second side 140 is profiled to mate with the open side of a second sig malignant, which will be referred to as left sig maligger 10L. On the left 140, the insulation profile 100 has a horizontal groove 141, the height of which corresponds to the height of the free lower side flange 23 of the sigmaligger 10. The horizontal groove 141 ends at a substantially vertical bottom 145. The material portion below that groove 141 is indicated as foot 152. As can be seen in figure 3B, this foot 152 in the assembled condition extends below the bottom flange 22 of the left sigmaligger 10L, and the top wall 144 of said groove 141 rests on the end face 25 of the free bottom side flange 23 of this left side. sigmaligger 10L. It is this foot which, in the mounted condition, always provides the complete insulation downwards of a beam. In the exemplary embodiment shown, in the top wall 144 of the groove 141, adjacent to the bottom 145 of the groove 141, a recess 147 is formed for receiving the end face 25 of the left sigmaligger 10L, said recess 147 having a corresponding width. with the width of the end face 25. On the right side 130, the insulating profile 100 has a projecting nose 131 with an extremity 135. From that extremity 135 extends downwards a sloping bottom surface 132, which in the assembled condition rests on the oblique connecting plate 28 of the right sigmaligger 10R and is therefore also indicated. as support surface 132. The angle which the support surface 132 makes with the horizontal, i.e. with the lower surface 120, corresponds to the angle which the oblique connection plate 28 of the sigmaligger 10 makes with the horizontal, and the size of the support surface 132 corresponds with, or is greater than, the size of the slant connection plate 28. The width of the insulation profile 100, measured between the bottom 145 of the groove 141 and the extremity 135 of the nose 131, corresponds to the mutual distance between the sigliggers 10, measured from free lower side flange 23 to web 11. The insulation profile 100 is then enclosed. . The isolation profile 100 cannot move to the right, because the extremity 135 of the nose 131 touches the body 11 of the right sigmaligger 10R. The insulation profile 100 cannot move to the left, because the bottom 145 of the groove 141 touches the free lower side flange 23 of the left sigmaligger 10L. More in particular, the bottom 145 of the groove 141 has at its underside an oblique transition portion 146 to the underside 143 of the groove 141. This shape of the bottom 145, 146 provides space for the free lower side flange 23 of the left sigmaligger 10L. when the insulation profile 100B is tilted during installation (see figure 3A), while in the assembled condition (see figure 3B) the inclined transition portion 146 presses against the free lower side flange 23 of the left sigmaligger 10L, while the free end edge of the depression 147 presses end face 25 opposite bottom 145 sidewall 142 of depression 147, effectively pushing insulation profile 100B to the right to press extremity 135 of nose 131 against body 11 of right sigmaligger 10R . The insulation profile 100 cannot sink down on its left side, because the top wall 144, 147 of the groove 141 rests on the end face 25 of the left sigmaligger 10L. The insulation profile 100 cannot sink downwards on its right-hand side, because the support surface 132 of the nose 131 rests on the oblique connecting plate 28 of the right-hand sigmaligger 10R. The insulation profile 100 on its right side also cannot slide off the oblique connecting plate 28 of the right sigmaligger 10R, because the insulation profile 100 would then have to move to the left, which is not possible, as mentioned above. Figure 3A shows that the insulation profile 100 undergoes a downward rotational movement during installation, wherein the rotation axis substantially coincides with the free end edge of the end face 25 of the left sigmaligger 10L. For the sake of explaining the further shape details, this rotational movement will be discussed in reverse for convenience, i.e. from the situation illustrated in figure 3B to the situation illustrated in figure 3A. When turning the insulation profile 100 upwards, the extremity 135 of the nose 131 must remain clear of the lower end edge 16 of the left side flange 14 of the right sigmaligger 10R. This defines a maximum height for the extremity 135. Preferably, the height of the extremity 135 is selected to be equal to, or slightly less than, this maximum height. Above the extremity 135 there is a receding sidewall portion 133. In principle, its shape is not critical. The receding sidewall portion 133 may be curved along a circular arc tangent to the lower end edge 16 of the left side flange 14 of the right sigmaligger 10, but preferably consists of one or more straight faces lying within this circular contour. Likewise, the lower right edge 123 of the insulating profile 100 must remain clear of the foot 29 of the right sigmaligger 10R. A right side wall portion 134 between the support surface 132 of the nose 131 and the lower surface 120, which is at an angle with the horizontal greater than the angle which the support surface 132 makes with the horizontal, may be bent along a circular arc tracing the foot 29 of the right side wall. sigmaligger 10R, but is preferably a straight plane that lies within this circular contour. In principle, the length of the support surface 132 of the nose 131 can be chosen freely. With a greater length of the support surface 132 of the nose 131, the intersection S between the support surface 132 and the right side wall portion 134 shifts up to the left and downwards. In an extreme case, this intersection point S coincides with the lower right edge 123. As will become clear from the following, however, this will have the consequence that the foot 152 of the insulating profile 100 becomes longer. This is undesirable, because the total width of the insulating profile 100 then becomes greater, and because the foot 152 of the insulating profile 100 then becomes vulnerable and the risk increases that it will break off, in whole or in part. Figure 4 is similar to Figure 2, but shows some auxiliary lines to clarify the following explanation. Lines marked with V are vertical guides. L1 is an auxiliary line connecting the center of rotation 142 with the lower right edge 123 of the insulation profile 100, and makes an angle q with the horizontal. With respect to the rotational movement of the lower right edge 123, this line L1 is the radius, and the rotational displacement of the lower right edge 123 will initially be perpendicular to this line. A line L2 perpendicular to this radius, tangent to the foot 29 of the right beam 10R, thus defines an extreme position for the lower right edge 123 of the insulation profile 100. Thus, when the lower right edge 123 lies to the left of this extreme position, the lower right edge 123 remains clear of the foot 29 of the right beam 10R upon rotation relative to the center of rotation 142. This applies irrespective of the angle of inclination that the right sidewall portion 134 makes with the vertical. The left side wall portion 154 between the horizontal groove 141 and the left bottom edge 153 of the insulating profile 100 makes the same angle with the vertical. The distance between the right lower edge 123 of the insulating profile 100 and the left lower edge 153 of the insulating profile 100 is equal to the pitch of the sigliggers 10. In the placed condition, the right side wall portion 134 and the left side wall portion 154 of two adjacent insulating profiles 100 close thereby well together, as clearly visible in Figure 3B. In principle, the intention is that the insulation profiles 100 are placed from left to right, ie 100A - 100B - 100C, etc. When an insulation profile is placed, its left neighbor is already in place. Figure A4 illustrates that the skew of the right sidewall portion 134 and the left sidewall portion 154 may be opposite to the skew illustrated in Figure 2 . Guideline L3 is a guideline connecting the center of rotation 142 to the top edge of the left sidewall portion 154; this line makes an angle 6 with the vertical. With respect to the rotational movement of the top edge of the left sidewall portion 154, this line L3 is the radius, and the rotational displacement of the top edge of the left sidewall portion 154 will initially be perpendicular to this line, indicated by a line L4, which makes an angle B = 180°-6 with the vertical. This defines an extreme angle for the inclination of the left side wall portion 154 of the insulation profile 100, and thus also for the right side wall portion 134. In practice, however, it may happen that the right-hand insulation profile 100C is already in place at the moment the left-hand insulation profile 100B is placed. It is desirable that the insulation profile is usable in this situation without further ado. In order to reduce the vulnerability of the foot 152, it is desirable that angle a is as small as possible and that the (horizontal in transverse direction of the profile! measured) length of the foot 152 is as short as possible. On the other hand, for the rotatability when a right profile 100C has already been placed, it is necessary that that angle is greater than . In an optimal situation, angle a is equal to, or slightly greater than, angle 9; preferably the difference between a and © lies between 0 and 5°. The intersection point S is preferably above the bottom 143 of the groove 141, more preferably above 80% of the height of the left side flange 24 of the beam 100, even more preferably above 90% of the height of the left side flange 24 of the beam 100, and optimally the intersection point S is only a few millimeters (0-10 mm, preferably 0-5 mm) from the top edge of the left side flange 24 of the beam 100. On the left side, the insulation profile 100 must remain free of the left sigmaligger 10L during rotation. The top wall 144 of the horizontal groove 141 is therefore shorter than the bottom wall 143 thereof. From the end of said top wall 144, a wall portion 148 extends vertically upwards, which in the assembled condition (see figure 3B) is sufficiently spaced from the plate-shaped body part 11 to allow concrete to fill the hollow space of the foot 29 . An oblique wall portion 149 extends obliquely upwards from the top edge of the wall portion 148 to the top surface 110. This oblique wall portion 149 may be partially curved, and/or may be provided with one or more bends. In the turned-up position (see figure 3A) of the insulation profile 100B, the nose 131 has passed the head 19 of the right-hand sigmaligger 10R, there is room on the right-hand side to move the insulation profile 100B to the right to release the groove 141 from the foot 29 of the left sigmaligger 10L, and the insulation profile 100 can be lifted out. It will be clear that when the insulation profile 100B is placed, the movements are carried out in the reverse direction and sequence. Figure 3A illustrates how to choose the orientation of said oblique wall portion 149: the angle of inclination relative to the vertical must be sufficiently large to remain clear of the body 11 of the left sigmaligger 10L. Said angle of inclination could also be chosen so large that said oblique wall portion 149 remains clear of the head 19 of the left sigmaligger 10L. In the exemplary embodiment shown, said oblique wall portion 149 adjoins the top surface 110 via a second wall portion 149' with a greater angle of inclination. Likewise, the receding right side wall portion 133 adjoins the top surface 110 via a second portion 133' of greater inclination angle. Figure 3C illustrates an example of a floor construction 200 with the sigliggers 10 and the insulation profiles 100 according to the present invention. The figure illustrates that the insulation profiles 100 are sufficiently strong to be able to support a concrete layer 210. The figure further illustrates that said wall portions 133, 133', 149, 149" define on either side of a portion of a sigmaligger 10 a funnel-shaped space 220, which is open at its top so that liquid concrete 210 can flow in there, up to the bottom flange. 22. On the left side of the sig maligger 10, the nose 131 abutting the web 11 prevents concrete from landing on the base 152. After curing, the concrete 210 increases the resistance to twisting by the sig malignant 10, which contributes to the rigidity of the sig malignant. sigmaligger 10 and of the total construction. After this, the floor construction can be further built up on the beams with a plate-shaped construction, or by arranging dovetail plates, on which a layer of mortar is then applied. As an alternative, it is also possible to pour the mortar layer directly through to a greater thickness, so as to immediately make the load-bearing floor, after which a finishing layer of cement or the like can be applied. The precise dimensioning of the angles of inclination of the wall portions 133, 133', 149, 149' can in principle be varied somewhat. The angle which the receding side wall portion 133 makes with the vertical is preferably chosen to be as small as possible, because then the bearing strength of the nose 131 is as great as possible. On the other hand, that angle should not be too small, because the necessary pebbles in the concrete 210 cannot pass the lower left end edge 16 of the head 19. Depending on the dimensions of the beams 10, that angle has a value in the range of 10-30 degrees, preferably about 20 degrees. Also depending on the dimensions of the girders 10, the receding sidewall portion 133 has a length of about 80 mm. The angle the second portion 133' makes with the horizontal is preferably in the range of 10-30 degrees, preferably about 20 degrees. The second portion 133' may also have a length of about 80 mm. Said oblique wall portion 149 also makes an angle with the vertical with a value in the range of 10-30 degrees, preferably approximately 20 degrees. The second wall portion 149' makes an angle with the horizontal by a value in the range of 10-30 degrees, preferably about 20 degrees. The greater those angles of inclination are chosen, the greater the volume of the funnel-shaped spaces 220 will be, and the greater the weight of the concrete 210 in those spaces will be, and too great a weight is in principle undesirable. On the other hand, these spaces 220 must not become too small, because then the concrete 210 does not support the sigmaligger 10 sufficiently. It will be clear to a person skilled in the art that the invention is not limited to the exemplary embodiments discussed above, but that various variants and modifications are possible within the scope of protection of the invention as defined in the appended claims. In a variant, the nose 131 does not have to abut against the body 11 of the right sigmaligger 10R, because the containment in the horizontal direction can be completely provided by the right side wall part 134 and the left side wall part 154 of the two adjacent insulating profiles 100. It has However, it is preferred that the nose 131 is pressed firmly against the body 11 of the right-hand sigmaligger 10R, because then a robust confinement of the insulating profile 100 is provided, and because then the carrying capacity of the nose 131 is as great as possible. Even if certain features are stated in several dependent claims, the present invention also relates to an embodiment having these features in common. Even if certain features are described in combination with each other, the present invention also relates to an embodiment in which one or more of those features are omitted. Features not expressly described as being essential may also be omitted. Any reference numerals used in a claim are not to be construed as limiting the scope of that claim.
