FIELD OF THE INVENTION The present invention relates to the field of prefabricated building elements, in particular for the realization of works such as swimming pools or pool elements. More particularly, the invention relates to a modular block to bancher and finds particular application in the realization of pool corner stair steps. BACKGROUND OF THE INVENTION Typically, such stairs consist either of a one-piece construction attached and attached to a wall or in the corner formed by two walls of the basin, or in a masonry structure, constructed as the construction of a wall, by stacking bricks, or pouring concrete into a formwork. Monobloc staircases are very expensive because they require large molds, they are also very bulky both in terms of storage and transport. In addition the number of proposed models is limited, so that they do not allow original achievements. The masonry staircases allow more originality, within the limits however of the structures used and the capacities of the installer. They also have drawbacks, in particular of a long implementation, more particularly when they are made of poured concrete, in particular for setting up the formwork. The traditional wooden formwork means must be removed after construction. Another formwork technique also conventionally used in the field of swimming pool construction, and especially the construction of swimming pool stairs, consists in using binder blocks which remain in the construction after the concrete has been poured. inside of them and has solidified. The currently used bunch blocks are of rectangular or cubic shape and require cutting and adjusting work in the particular case of corner stairs. These cutting and adjusting work can be difficult, time consuming and therefore expensive. Moreover, the exact dimensions of a corner staircase may vary according to the adjustments made to compensate for the inaccuracy of the cuts. It is therefore necessary to also adapt the exact dimensions of the flexible liner to each construction, which is also expensive and generates longer delivery times. In addition, the inaccuracy of the cuts and / or measurements may cause defects during the installation of the "liner", which may in particular cause sealing problems at the start of operation of the swimming pool.

By "modular block" is meant an element adapted to be assembled with other identical elements, using assembly means described in more detail below. The modular block 1 is in the form of a right prism whose faces A, B form the isosceles triangular bases.

The modular block 1 comprises a through-housing, advantageously defined by at least three walls 3, 4, 5 forming the rectangular lateral faces (C, D, E) of the right prism, which connects the first face A and the second face. B and serves to receive a filler material, in particular, concrete pouring. The through housing therefore has no closed wall at the sides A, B which makes possible the flow of the filling material through the modular block.

Preferably, the through-housing comprises a plurality of ribs 6 delimiting compartments of sufficient size to allow efficient flow of the filling material into the structure. By rib is meant a wall 15 internal to the housing through which at least one end can bear on one of the three walls 3, 4, 5 of the housing through. As illustrated in Figures 1 and 2, but by way of example only, the ribs 6 delimit 9 compartments 20 of different sizes inside the housing through. These ribs 6 and the walls 3, 4, 5 make it possible to stiffen the structure of the modular block 1 and reinforce its mechanical strength at the internal pressures exerted by the filling material.

The height h of the modular block 1 constitutes a dimension of the side wall 5. The triangular bases of the prism being isosceles, the two side walls 3, 4, called main side walls, are of identical dimensions. The two main side walls are arranged to form between it a given angle. This angle may be chosen to correspond to (or be a divider of) an angle of a swimming pool in which a stairway is to be formed. Advantageously, and as shown in the figures, the two main lateral walls 3, 3 form an angle of 90 degrees between them, which makes it possible to limit the number of modular blocks to be assembled to constitute the steps of a right angle staircase, which is the most common corner staircase.

The two main lateral walls 3, 4 comprise assembly means 2 for securing a plurality of modular blocks to be sandwiched together. These means comprise male-type members 7 and female-type members 8 to provide a sliding connection between two modular blocks. As shown in the figures, the male-type members 7 may be formed of tenons and the female-type members 8 of grooves whose complementary shapes cooperate to allow a dovetail type connection. In the particularly advantageous embodiment shown in FIG. 3, the post has different widths 1, 1 at the first face A and the second face B of the modular block. In the same way, the groove has different widths at the first and second faces A, B of the modular block. This particular configuration makes it possible to block the sliding of a tenon of a first modular block in a groove of complementary shape 25 of a second modular block during the assembly of two modular blocks. The assembly of two modular blocks is done by their respective lateral faces C, D; the blocks being head-to-tail, one having its face A facing down and the other having its side A facing upwards, the side face D of the first block is assembled with the face C of the second block, by sliding of the tenons in the grooves provided for this purpose.

Advantageously, and as illustrated in Figures 1 to 3, each main side wall 3, 4 has a shape defining a plurality of tenons and grooves, in particular 2 pins and 2 grooves, extending all along 5 these walls. In other words, the assembly means are integrated with the main side walls 3, 4. This preferred feature simplifies the manufacture of the assembly means and promotes the cohesion of assembled modular blocks.

In addition, a stop 9 may be present at the narrower end of at least one groove to lock the peg of another block in a defined assembly position. Advantageously, each groove has at the narrow end an abutment for adjusting the position and blocking the engagement of the tenons of another block in their final assembly position. Preferably, each tenon comprises a notch 10 at its narrower end adapted to cooperate with the stop 9 of the groove of another block, to block it in a defined assembly position. Thus each groove being provided with a stop and each stud being provided with a notch, the fitting of a first modular block on a second modular block will be easily adjusted and locked in its final assembly position. Figure 4 shows an assembly formed of a first row of modular blocks to bancher. This view shows the alternation of the exposed faces A, B between adjacent modular blocks, induced by the assembly mode described above. The stack of a plurality of modular rows or blocks to be closed can be made with a good alignment, by positioning the rows or blocks on top of one another and wrapping a rail in the opening formed by the alignment of a through compartment of each block. The size of the rail is adjusted to the dimension of the compartment of each block, so that the rail makes it possible to ensure the vertical alignment of stacked modular blocks. The assembly of a plurality of modular blocks to bancher, juxtaposed in rows, then stacked allows the construction of different masonry elements.

According to an advantageous example of implementation, such an assembly of modular bending blocks can be used for the manufacture of a pool corner staircase, as illustrated in FIG. 5.

The manufacture of a swimming pool requires the casting of a concrete structure, in particular for the construction of the raft and the walls thereof. The implementation according to the invention allows pouring the concrete at once, for the raft, the walls and pool stairs. The assembly of the modular blocks in rows is carried out by interlocking the blocks into each other via the assembly means, as described above, and without cutting. Each row can come to bear, at its ends, on the perpendicular walls of the swimming pool. Optionally, support rails 12 may be attached to the pool walls or to the ground to support the first rows; these first rows may also be supported by at least one central support rail and / or at least one stud fixed on the ground. These rails and / or pads are positioned to flush with the level of the final bottom of the pool and allow to adjust the level of the staircase, before the flow of concrete. The sidewall 5 of the modular blocks will constitute the exposed face of the counter-step. And the height h of the modular block will constitute the walking height. For example, this height may be between 5cm and 50cm, preferably its dimension will be 30cm. Advantageously, when the two main lateral walls are orthogonal, the running depth is defined by the half-width of the side wall 5 of the modular blocks. For example, it may be between 15 and 40cm, preferably its dimension will be 30cm.

The first row to be positioned for the development of the staircase is the row R1 of the step M3 which can be seen in FIG. 6 showing the sectional view of the right-angled staircase of FIG. a bisector plane. This is wedged against the walls of the pool 14 and optionally on the rails (12) or support pads. The row R2 of the step M3, then the row R3 of this same step are then stacked on the row R1 to form this step. To ensure the alignment of this stack, a rail 11 is introduced vertically into an opening formed by the alignment of the through compartments of the modular blocks. As shown in Figure 2b, the rail 11 is an example and as introduced into the adjusted to allow alignment 30 stacked and more particularly stacked. The length of the rail width of the rail is such that the vertical rail of modular blocks of modular block rows 11 is adjusted to the number of compartments 13. The size of the compartments, rows stacked: it must be long enough to pass through the stack modular blocks, thus ensuring its alignment function superimposed rows.

After assembly of the step M3, that is to say the superposition of the three rows R1, R2, R3 and the positioning of the alignment rail, the assembly can be held in position 5 by fixing elements. , such as screws, against the walls of the pool. The assembly of steps M2 and M1 is then carried out in a manner similar to that just described for step 10 M3. The assembly of modular blocks as described above and illustrated in FIG. 5 is ready for the subsequent strapping operation. The filler material, such as concrete, is poured to form the pool floor and bring the final soil flush with the step Ml. The material may be cast at the modular block assembly; it flows through the through compartments to the ground, and until filling and outcropping at the 20 steps Ml, M2, M3. After drying, there is obtained a pool angle staircase, not requiring cutting, poured simultaneously with the raft and the walls of the pool, thus forming a monobloc structure with the entire basin. Its dimensions are precise and reproducible. In addition, the monobloc character gives great strength to the structure. In the example according to Figure 5, the corner stair 30 has 3 steps whose dimensions are defined by the size of the modular blocks. The standardization of the dimensions of a corner staircase advantageously allows the standardization of flexible envelopes ("liner"), leading to lower costs and shorter delivery times.

The modular block and the juxtaposition and / or stack assembly according to the invention are not reduced to this sole use. They may for example also be used for the construction of straight staircase or walls to bancher. For this purpose, it will be possible to provide a second category of 10 modular blocks of different shape and complementary to that exposed, so as to be able to define lost formwork of any shape and dimension without necessity or by limiting the modular block cutting to bancher.
