Definitions
- the subject of the invention is essentially a block forming a lost formwork element, in particular for the construction of civil engineering works, in particular swimming pools or water retention basins, which may be equipped with a liner (internal pocket of 'waterproofing), structures which must have a mechanically resistant reinforced concrete wall.
- the present invention relates to a block which in a way achieves the synthesis of the two previous types of construction, but which also offers many other advantages in particular as regards ease and safety of use, in particular for laying, sealing and ease and precision of setting up all the organs and equipment for operating the basin.
- a block forming a lost formwork element in particular for the construction of civil engineering works and in particular of swimming pools or water retention basins having to comprise a mechanically resistant concrete wall, elementary block being in position d use in the form of a rigid block, of generally rectangular parallelepiped shape, providing between its two main opposite faces a hollow volume for pouring concrete, essentially consisting of two assemblable parts, each comprising a main face mentioned above of which are integral and come from one side of the bracing elements regularly spaced from each other, said two parts in the assembly position coming to bear and lock against one another by the ends of said bracing elements, is characterized according to the invention in that said bracing elements have the form of wells of substantially cylindrical section whose volume occupies substantially at least 40% of the volume of the block and preferably at least substantially 45% of this volume.
- the two aforementioned parts of the elementary block are identical, their assembly and locking being effected by complementary members facing each other when the two identical parts of the block are applied to each other.
- elementary which are oriented by being turned 180 ° relative to each other, the adjacent elementary blocks locking by simple pressing against each other by means of complementary locking members provided in particular on their edges.
- the bracing elements in the form of wells of substantially cylindrical section have a polygonal section and occupy most of the width of the block. This configuration makes it possible to improve, for the same weight of material, the resistance of the mechanical block made up of these two parts snapped onto one another and also facilitates the locking-snapping of the two parts.
- each elementary block has on its upper edge a groove forming a groove for the attachment of the liner.
- a block forming a concrete pouring wall element on the height of the wall of the structure each aforementioned part of the block comprises several aforementioned bracing elements, aligned in the direction of the height, and a channel capable to house a seal over the height and the edge of the part in question, a seal which is compressed by the edge shaped in a complementary manner to the next adjacent similar block.
- FIG. 1 shows, in perspective view, two identical parts before locking one on the other, presented in the position where they will come to lock one on the other, to form the elementary formwork block lost according to this embodiment of the invention
- - Figure 2 shows like Figure 1, but on a smaller scale, two blocks forming a lost formwork element, each consisting of two parts, the four parts thus being assembled into a wall formwork element formed of two adjacent elementary blocks;
- FIG. 3 shows, on a larger scale, in perspective view, the corner portion indicated III in Figure 2;
- FIG. 5 shows, in perspective view, from the inside, a part of an elementary block before its assembly with another identical part
- FIG. 6 shows, on a larger scale, in perspective view and with cutaway, how we will be able to come fix and embed on and in the elementary blocks according to the invention various organs such as for example a surface skimmer and a water return nozzle by knocking down certain marked parts of the main surface of the two parts constituting an elementary block;
- FIG. 7 is a sectional view, on a larger scale, of a detail showing the locking and sealing between two blocks adjacent, this view being made at the level of the section marked VII - VII in FIG. 2.
- FIGS. 1 and 2 of the drawings describe the main parts and their elements and members making it possible to constitute an elementary block of lost formwork.
- the two parts 1a and 1b are the same, that is to say identical, manufactured for example by molding in a suitable plastic material such as polypropylene (PP), polystyrene or polyethylene terephthalate (PET), the part lb being identical to the part la after having simply undergone a rotation in the direction of the arrow R of 180 ° so that its bracing elements, coming from each main face of the part la or lb, can come to lock in correspondence.
- PP polypropylene
- PET polystyrene or polyethylene terephthalate
- each part 1a, 1b, of this surface inwards in the assembly position of the elementary block 1, come from the elements d 'bracing, in the example shown four in number, respectively 11a, 12a, 13a, 14a, for part la and 11b, 12b, 13b, 14b, for part lb.
- the bracing elements in question have a general shape of cylindrical well with polygonal section, which occupy most of the width of the element, for example around 70 to 80% of this width while being centered on the longitudinal median plane of the elementary block. In the example illustrated, and as we can see more clearly in FIG.
- each well is formed from a polygon with fourteen sides referenced a) to m), some of which, like the sides g) and n), have protruding tongues 15, provided with teeth 16, which go come to hang and snap into corresponding recesses or openings 17 of the complementary part (sides b) and i)) with which the part shown will come together to form an elementary block, either assuming that we have represented in FIG. 5 part 1b: part 1a.
- FIG. 1 reference has been made, so as not to overload the drawing, only the side of the wall n) of the well 11a whose teeth 16, formed on the tongue 15, will come to lock in the recesses 17 formed on side i) of the corresponding well 11b.
- each elementary block such as 1, consisting of two identical parts 1a, 1b, simply positioned opposite one another, by simple snap-fastening and will confer to this elementary block a great rigidity, in particular in crushing taking into account the ribbed polygonal cylinder shape, crenellated and formed with slight steps in the radial direction, as it clearly appears from the drawings.
- the seal 23 bypasses a groove 27 formed on the main face 10b of the part 1b, on the outside of the block.
- This groove 27 will be used to hook the upper edge of the liner if it is this side of the panel which is directed towards the water of the basin.
- the symmetry of construction in fact means that the panel can be indifferently positioned on one side or the other, since we find on the part la, also in the upper part, the groove 27.
- these blocks At their base, they have feet such as 30 on which they will rest at the bottom of the excavation dug to receive them.
- recesses such as 31, 32, for the passage of reinforcement and the pouring of the concrete advantageously in one go with the concrete of the raft (not shown).
- Each foot also has a projection on the side, a housing 33 for receiving a jack foot 34 screwed into the housing 33 and allowing the adjustment of the verticality.
- Each elementary part of the wall may include in a suitable place a small integrated level (not shown) allowing immediate verification of the verticality and the horizontality.
- each elementary block part has grids and various markings which, in practice, will appear slightly visible from the outside. These markings allow, at suitable places, to smash a part of the wall to receive the various operating components of the basin.
- straddling two elementary blocks 1, 2 we will be able to smash a rectangular part which we see three of the angles referenced A, B, D, to receive an entry of water 35 from a surface skimmer 36 which can be positioned directly in the formwork panel before pouring the concrete.
- a water outlet 37 engaged by knocking out the central part of the second well of the elementary block 2 encountered while descending from the upper part of the panel.
- the elementary blocks made up of their two identical assembled parts such as 1a, 1b, can be stacked sheaves, one on the other, the projecting feet 33 of a block being received in the recesses 38 provided in longitudinal symmetry of an underlying elementary block. This ensures perfect formation of batteries for storage and transport.
- the volume of the recesses left between the bracing elements are calculated to allow the passage of reinforcing bars (not shown) and the subsequent pouring of concrete between these elements, allowing the construction of a freestanding civil engineering structure.
- the volume of the "voids" (in the wells) compared to the "full" of the irons and concrete of the construction preferably being of the order of 40 to 45% of the total volume
- knockouts are provided, such as for example the part referenced 39 in FIG. 1, for the passage of locking irons with the beach which surrounds the basin.
- these blocks can be fitted directly in the factory with the provided equipment, such as surface skimmer, discharge outlet of water, basin lighting device, etc.
