Definitions

  • the invention relates to a concrete floor to span the distance between two supports, consisting of a plate-shaped part, reinforced and with a smooth surface, with underneath it, running in the direction of the span length of support, forming one whole with that part, prestressed concrete beams.
  • Such a concrete floor is for instance known from the published European patent application no. 87202345.2, publication no. 0273492.
  • beams of prestressed concrete which are previously, separately manufactured and cured, lifting of the floor at a later date is prevented.
  • the construction with the prestressed beams has as a further consequence, that at a similar distance to be spanned and at the same requirements as to strength imposed on the components, a thinner plate-shaped part will suffice.
  • a floor of such a construction may span, at a width of 3 meter, a distance of 6 meter, resting thereby on four supporting points.
  • the floor should have a thickness of for instance 10 cm.
  • a concrete floor according to the invention thereto shows the characteristic that - in combination with the afore-mentioned prestressed concrete beams, between them vertical zigzag reinforcements - girders - are diagonally placed on those beams, each consisting of two, mainly parallel rods that form part of the reinforcement in the plate-shaped part, a parallel thereto, underneath the floor and between the beams running third rod - the tie rod - and in each of the fields, defined by a first rod and the tie rod and by a second rod and the tie rod, a zigzag formed rod that with its upper ends is connected to the first rod and the second rod respectively and with its lower ends to the tie rod.
  • the reinforcement in the plate-shaped part goes both in the longitudinal direction and diagonally. Hence it concerns here the combination of the application of two measures, which each on itself already lead to a thinner floor - and hence to saving of weight - for a spanning of a certain length, with a certain width and satisfying certain requirements as to strength imposed thereon and which in combination may lead to a floor that, when only using the prestressed beams, demands a thickness of 10 cm, now only requires a thickness of 5 cm.
  • Such a floor has also as an additional advantage that the transverse reinforcement may serve as support for the pipes etc. which might be installed underneath the floor.
  • the floor according to the invention has various versions, of which some preferred embodiments.
  • a preferred form of a floor according to the invention is characterized in that the prestressed beams run in the direction of the largest span length of support. In that case, the most benefit will be gained from the construction according to the invention.
  • a floor is preferably, at its bottom, at the corners, provided with support elements.
  • the use of support elements makes it possible to exactly equalize the distance between the floor surface and point of support-the bottom of the element -, so that a flat bearing of the floor is guaranteed. The latter is in particular important when some floor elements are placed against each other and thereby roughnesses at the transition of one element to the other, must be prevented.
  • these support elements are mounted on the prestressed beams - and this by means of anchoring plates that are at the far ends of the prestressed beams. Further, they are preferably also mounted on the plate-shaped part in behalf of the transfer of moment thereon. Cases are successfully used as support elements in which for instance the posts, columns that bear the roof or floor lying thereon, may find a place.
  • the bottoms of the ends of the prestressed beams are used as support points.
  • the protruding piece of that part may also serve as support point.
  • the invention also includes a method to make concrete floors as described afore.
  • the plate-shaped part with the smooth (floor)surface 2 is 1.
  • the prestressed concrete beams 3 and 4 which stretch in the direction of the span length of support underneath the plate-shaped part. In the case drawn: in the direction of the largest span length of support.
  • the support elements 5, 6, 7 and 8 which, in the drawn example, consist of (vertical) cases. These cases 5, 6, 7 and 8 form with their bottoms the bearing points for the floor.
  • a floor of this type is constructed according to the method of the invention by pouring concrete mortar at the smooth bottom of a (steel) mould, it will be possible, before the concrete mortar is poured, to place on that bottom, there where the corners of the floor will be, said cases.
  • the distance between the floor surface 2 and a bearing point is always the same and that hence a floor can be laid exactly horizontal and that floor elements can be put against each other without discontinuities - staggerings - appearing in the thus to be formed larger surface.
  • the zigzag reinforcement running according to the dotted lines 9, 10 etc.
  • This zigzag reinforcement is shown in more detail in figures 2 and 3, in which 1 is again the plate-shaped part with surface 2; 3 and 4 are the prestressed beams, which at the corners are flanked by the support elements 5 and 6. Between the beams 3 and 4 runs the zigzag reinforcement, which consists of the zigzag rods 11, 12 etc.
  • a row of zigzag reinforcement consists of two zigzag rods 11, 12, each starting from the tie rod 17, connected to an 'own' rod 13 and 14 respectively in the plate-shaped part 1.
  • the zigzag rods 11 and 12 are each lying in an own flat surface, which two surfaces enclose at the tie rod 16 a sharp angle ⁇ .
  • Fig. 4 which is a sectional view of the floor according to A-A, it is clearly to see how a zigzag rod 11 or 12 is fastened to a rod 13 and 14 respectively, which form part of the reinforcement in the plate-shaped part 1. With 18, the reinforcements in the prestressed beam 3, 4 are indicated.
  • Fig.5 shows a similar sectional view of the floor, but now of a floor in which insulation 19 and 20 have been fitted.
  • Fig.6 and Fig.7 show sectional views of the floor according to B-B, without and with insulation respectively.
  • Fig.8 shows a top view of a corner of a floor, with therein a case 5 and in Fig.9 it is drawn how that case 5 via the anchoring rod 23 has been anchored into the plate-shaped part 1 and into the end of a beam 3 and 4 respectively.
  • a prestressed beam 3, 4 is provided at its top ends with steel plates 16 that have been put in before pouring the concrete mortar. Those plates 16 are being kept at the desired distance with respect to each other by the anchoring rods 21.
  • the cases 5 - or possibly other support elements - have been fastened to the plates 16 by welds, or with the help of bolts.
