Definitions

  • This invention relates to prefabricated articles in reinforced concrete for making circular tanks set in or out of the ground.
  • the method is concerned with blocks with arc cross-sections and lateral self-centring joints.
  • the blocks are laid side by side to form the vertical circular wall of the tank and are held together by tension cables placed around the outside of the walls of the tank.
  • the blocks have ribbing shaped for the seatings of the tension cables.
  • the cables are thus positioned exactly during assembly and afterwards remain hidden from view.
  • tanks there are numerous sectors which may require tanks to be constructed, especially of the above-ground type which can be produced with prefabricated parts and are thus cheaper, easier and quicker to construct.
  • Tanks of this kind are often used in agriculture for water or detritus storage, or in industry for filters or similar such purposes.
  • these tanks are circular in shape because it is this form which ensures a more uniform distribution of internal forces and pressure, takes up the least surface area in relation to capacity, and is easier rig up and construct.
  • an iron beam is first set up or a mounting with means of attaching the tension cables, fixed to appropriate previously-prepared foundations.
  • the various panels are then positioned side by side, held in place by bracing elements.
  • the tension cables are wound around the tank with their ends anchored to the iron beam for tightening to be carried out.
  • the invention in question proposes manufactured articles and a related construction method for making circular tanks both out of and in the ground.
  • Each of these arc cross-section manufactured parts has a self-centring joint externally and ribbed channelling for the tension cable seatings which are thus automatically positioned and hidden from view.
  • This seating can then be filled with mortar or any other suitable material to protect the cables from external agents.
  • a tank out of the ground is created by the combination of a number of blocks and panels (1), joined and fixed at their extremities to a head element (2) which is mounted on a foundation plinth (3).
  • Each of these blocks has an arc cross-section (Fig. 7) viewed from above and has the sides 4 and 5 shaped respectively male and female for a self-centring joint with the adjoining panels.
  • each of these blocks has a series of essentially horizontal ribbing, illustrated in detail in Figure 9.
  • the ribbing (6) creates a raised border or parapet (7) on the external part of the block thus forming a seating between the wall of the panel and this border for the tension cables (8).
  • the upper wall (9) of each rib is not flat but is raised in the centre so that the bottom of ribbing slopes from the centre outwards.
  • the ribbing (6) is slightly shorter than the panel itself so as to leave a small space between adjacent ribbing when construction is complete, as shown in Fig. 8.
  • the distance between the ribbing is not constant. Lower down on the panel the ribs are closer together, where the hydrostatic pressure exerted on the walls is greater and where the cables around the panels must thus be closer together.
  • the head element (2) (Figs. 10,11 and 12) also has an arc plan cross-section. but without ribbing. It is thicker than the other blocks, essentially equal to the thickness of the panels (1) plus that of the ribbing, with the central part enlarged to contain the ends of the cables (8) to be tightened, giving a firm anchorage.
  • the head element (2) is mounted on a plinth (10) with a seating (11) shaped to allow (1) the insertion and fastening of the element (2).
  • a foundation kerb and plate are set out, on which the various blocks are placed.
  • the plinth is then put in position and the head element assembled, fixing it temporarily with two wedges or similar objects.
  • the various blocks are then put in place side by side bringing the lateral walls together and fixing them, again temporarily, with a gusset plate, a clamp or similar system, with the first and the last block fixed to the head (2).
  • a sealing gasket (10) (Fig. 8) is placed between adjacent blocks, made of Neoprene or similar material.
  • tension cables can be put in place. They are simply inserted in the ribbed seatings (6) with the respective borders (7) and anchored at their ends to the head element (2).
  • the gusset plates which held the blocks together can be removed and finishing operations carried out - e.g. applying a layer of sealing glue (11) along the internal edges of the blocks (Fig. 8), filling the seatings with mortar or similar material thus protecting the cables from possible damage and from atmospheric weathering.
  • Water drainage is improved in the cable seating area, which can also be protected with a filling of mortar or other suitable material.
