Definitions

  • the invention relates to a building structure as described in the preamble of claim 1.
  • this known floor can be constructed with a low rate of concrete and steel the invention does have for its object to save even more material while maintaining the same quality of the structure or to improve the quality of the structure without using more material.
  • the structure according to the invention is characterised as described in the characterising clause of claim 1. Due to the fact that the tension cables are concentrated in the regions of the columns, the support strips can be considered as supporting elements sufficiently describing the main static behaviour of the floor. Once having dimensioned these support strips the remaining parts of the floor can be easily dimensioned by considering the remaining parts to be elastically supported by the support strips.
  • the design can be based on a chosen column dimension.
  • a maximum saving of material can be obtained by selecting the rigidity of columns and support strips so as to. match one another. This is described in claims 2 and 3.
  • the support strips and the floor slabs constitute a plate-shaped monolith of substantially uniform thickness.
  • the tension cables are bent over outwardly, viewed from the upward direction, at least into a horizontal direction near the rims of the floor above the columns in this area.
  • part of the load is directly transferred to the column standing at the edge of the building structure, so that shear stress due to punching effect is reduced.
  • the building structure 1 embodying the invention comprises a plurality of columns 2, 3, that is to say, inner columns 2 and peripheral columns 3, and a plurality of floor slabs 4.
  • each floor 4 is considered to comprise a grating of support strips 5 connected with the columns 2, 3 and floor slabs 6 supported by the support strips 5.
  • Figure 3 shows a calculation model in which the support strips 5 form a grating having recesses 11, which are covered by floor slabs 6 (not shown) supported by the support strips 5, said support strips 5 and said floor slabs 6 constituting a plate-shaped monolith of substantially uniform thickness as is illustrated in figures 1 and 2.
  • the support strips 5 extend through the punch region 8 indicated in figure 4 by dot-and- dash lines 7 across the columns 2, 3 and have uninterrupted tension cables 9 and 10 respectively, which extend preferably, but not necessarily from one edge 12 to the opposite other edge 12 of the floor 4. If the support strips 5 form a monolith with the floor slab 6, they have a width of about 1/6th to 1/3rd of the span between the columns 2, 3 so that some of the tension cables 9, 10 may extend outside the punch region.
  • the tension cables 9, 10 with sufficient concrete coating extend in the middle of the support strips 5 at the lowest possible level and above the columns 2, 3 at the highest possible level, so that they have a slight S-bend on either side of the middle 13 of the columns 2.
  • the tension cables 9, 10 have an S-shaped bend, of which figure 6 only shows the upper part.
  • the tension cables 9 and 10 are bent over near the edges 12 above the local peripheral columns 3-viewed in outward direction- from the upward direction 15 at least to a horizontal direction 16 (see figure 11). Thanks to this bend the tension cables 9, 10 directly transfer part of the load to the columns 2, 3 so that shear stress due to punch effect near line 7 in the concrete 2 is reduced (see figure 12).
  • the tension cables 9 and 10 are arranged in envelopes 18 and stuck to said envelopes 18, as the case may be, by means of an adhesive introduced through hoses 17 after the tension cables 9, 10 have been pre-stressed and fixed to anchors 19.
  • Figure 13 shows the disposition known per se of the anchor with respect to a casing plate 20 prior to pouring of the concrete 21.
  • the floor 5 Apart from the tension cables 9, 10 the floor 5 comprises mild steel reinforcing networks 23.
  • the columns 2, 3 comprise steel reinforcing bars 24, each extending throughout the column 2, 3 concerned.
  • the support strips 5, and-their reinforcement, in particular the tension cables 9, 10 are proportioned on the assumption that the support strips 5 are each clamped tightly in the columns 2, 3 taking into account the rigidity of the columns 2, 3.
  • the support strips 5 and their reinforcement according to the invention can have smaller dimensions, which implies considerable saving the material.
  • the floor 4 has a uniform thickness d throughout its surface. Therefore, the aforesaid peripheral region 26 is determinative of the floor thickness d. It is even more preferred to construct the inner columns 2 and particularly the peripheral columns 3 with such a rigidity that the calculation concerned is a near approximation of that of figure 10. It is still more preferred to choose an optimum situation in which the cost of the columns 2, 3 and the support strips are minimized. This can be achieved by selecting the rigidity of the support strips 5 and that of the floor columns 2 and 3 and/or the span between the columns 2, 3 so as to match one another. Comparing figures 5 and 6 it will be obvious that the invention can be applied in the case of a rim 12 protruding like a collar or not protruding.
