Definitions

  • This invention is related to a wall of pre-cast panels, suitable for retaining earth and generally embankments and for building liquid-holding tanks.
  • the invention is directed to a wall erected by placing side by side a plurality of panels having a substantially T-shaped horizontal cross-section, the panels being laid on a pre-cast support floor and being joined with a reinforced concrete foundation bed, which is cast in place, said panels being then structurally bound to said foundation bed when erection is completed.
  • the invention is substantially directed to avoid these drawbacks. More particularly, the most important objects of the invention are:
  • the invention provides a wall of pre-cast panels adapted to structurally cooperate with a cast-in-place, reinforced-concrete foundation bed, each panel comprising a facing and a back rib at right angles to the facing and integral therewith; the facing and the rib extending downwardly into substantially tripod-shaped support members; characterized in that each panel further comprises:
  • 10 is a pre-cast panel
  • 40 is a reinforced-concrete foundation bed, which has been set up and cast in place
  • 30 is a support floor for the wall, formed with concrete cast over a light reinforcement.
  • Each panel 10 comprises a facing 11 and a rib 12, the latter being at right angles with the facing and integral with it.
  • facing 11 and rib 12 extend into a front support member 13 and a back support member 14, substantially laid as a tripod; a central front extension 13a, intermediate between members 13, does not have a support action, but only a retaining action for the reinforcement of the foundation bed, as it will appear from the following disclosure.
  • a bare portion of reinforcement 9 of panel 10 extends between members 13 and 14, so that it can be buried in the foundation bed.
  • Levelling screws 16 and 17, respectively, are provided on the support members 13 and 14, in order to adjust plumbing of the panel when the latter, during installation, is erected on the supporting floor.
  • each levelling screw is engaged in a corresponding threaded sleeve 18, which is provided with retaining rag bolts 19 and is buried in panel 10 during casting. Screws 16-17 cooperate with corresponding first metal plates 31, which are buried and bolted in the cast of the support floor.
  • Second metal plates 21-22 are provided on, and bound to, the support members 13 and 14.
  • said second plates 21-22 are channel-shaped as shown at 210 on Fig. 3, and therefore contain the ends of each corresponding support member 13-14; holes are provided in the lower parts of said channel plates for insertion of levelling screws 16, 17, respectively.
  • the first and second metal plates above described cooperate with retaining angle members 24 which, after erecting and plumbing the panel 10, are rigidly bound to the plates, preferably by means of weld beads 25-26, in order to provisionally stabilize the panel.
  • a plurality of panels are erected, plumbed and provisionally stabilized as explained above, in side-by-side relationship as shown on Fig. 4, upon support floor 30, which has been previously cast, reinforced and set.
  • Facings 11 of said plurality of panels can lie in one plane or in mutually intersecting planes, in order to impart the wall a profile having a desired shape, comprising a ssuccession of concave and convex, as well as rectilinear, portions.
  • edges of the facing in each panel are provided with cylindrical hinge members having conjugated profiles, respectively a male member 27 and a female member 28.
  • the hinge male member 27 of each panel will engage the hinge female member 28 of the adjacent panel.
  • the reinforcement 41 of foundation bed 40 is laid. As shown on Fig. 4, the reinforcement 41 includes transverse and longitudinal stirrup rods 42 and 43. Stirrup rods 42 are housed in the ports between the front support extensions 13 ahd the intermediate central extension 13a, the latter being provided to this purpose.
  • Foundation bed 40 is then cast. This incorporates reinforcement 41 and the reinforcement portion 9, thus forming the finished wall. If the wall is intended for retaining liquids, e.g. being the wall of a tank, the joint between facings 11 and the foundation bed 40 will have to be hydraulically sealed, as shown by 50 on Fig. 1; and hinges 27-28 will also have to be sealed, as shown by 51 on Fig. 8.
  • a web 120 is provided on the edge of rib 12, the web being able to act both as a tie and as a strut.
