    jobs. In addition, this form of stacking allows a decrease in the height of the center of gravity, which results in an increase in the stability of the structure.
    On the other hand, the proposed solution, due to the support system with the seat cradles of the bottom row of the stack of the hollow structures designed for this purpose, due to the configuration of said seat cradles, allows the adaptation to the irregularities of the where it will be stored, thus improving the solutions of other conventional systems.
    In addition, due to the mooring system of the traced hollow structures, it allows a certain transversal deviation between the hollow structures of the lower row, so that a better use of the space can be obtained. The hollow structures of the lower row can be diverted from the nominal position to avoid elements that can be found in the storage area and that cannot be removed, such as pipes, tank vents, etc.
    The proposed system of the invention allows cross-sectional storage from one to an unlimited number of tubular elements and the ski lift or stacked from one to an unlimited number of elements, depending on this ski lift, due to the lateral distribution of the load used by the system of subjection, only of the number of hollow structures of the lower row.
    The proposed restraint system improves existing solutions as it improves the conditions of stability, flexibility, adaptability to the terrain and compactness of the load, thus obtaining a better behavior of the load, especially in the maritime transport. With this system the number of chains or slings necessary for the lashing of the load is also reduced, thus reducing the time of the operation, and therefore the cost thereof. On the other hand it allows stacking in the port or in the field of materials, thus reducing the cost of storage.
    Next, in order to facilitate a better understanding of this descriptive report and forming an integral part thereof, a series of figures are attached in which the object of the invention has been shown as an illustrative and non-limiting character.

    Modular (2) is anchored to adjacent ones by pairs of twisted connection mechanisms comprising male elements (5) and female elements (6). In addition, the modular device is linked to each of the ends of the hollow structures (1) by means of a jaw mechanism that holds a centered lower part of each end of the hollow structures (1) to the respective modular device through the mechanism of jaw.
    In principle there are three different modular device structures: a first structure (2a) that is located in a lower row of hollow structures (1) that are in contact with the ground (7), a second structure (2b) that is located in intermediate rows of hollow structures (1) and a third structure (2c) of modular device that is located at the top of the group of stacked hollow structures (1), where the modular device holds a hollow structure (1) seated tangentially on two hollow structures (1) placed in a row immediately below the only hollow structure (1) of the highest row in the stack of hollow structures (1). Although normally there is only one in the upper row of the stack of hollow structures (1), it is also possible to arrange several hollow structures (1).

    The staples (12) are anchored to a sheared rib (29), (29 ’) that are welded to the gluttony supplements (11) and upper sections of the frame branches (9), as will be described in detail below.
    The second structure (2b) of modular device comprises the same elements as those of the first structure with the exception of the seat cradles (13).
    The third structure (2c) of modular device comprises the support base (8) and two vertical collateral reinforcements (10 ’) that have a stair-shaped configuration.
    The lower inclined planes (4) of the support base (8) of the first modular device structure (2a) are in contact with a curved-convex inclined planes (13a) of the seat cradles (13) that allow these to support in the ground (7) maintaining stability even if there are irregularities in said ground (7). In order to achieve this effect, apart from the curved-convex inclined planes (13a), the seat cradles (13) are loosely coupled to the support base (8) by means of pairs of facing lugs (15) integral with the cribs. of seat (13) in combination with bolts (16), so that said loose coupling allows the seat cradles (13) to be tilted so that they find the stable support on the ground (7) of the first structure (2a) Modular device

    modular, said worm screw being coupled to the support base itself (8), wherein said worm screw (19) threads into a lower nut (19b).
    The auger screw (19) is inserted through through holes in the support base (8), so that said auger screw (19) is fixed in position by the lower nut (19b) to prevent it from disassembling by itself unwittingly. Therefore, the only function of the lower nut (19b) is to keep the screw (19) in position. On the other hand, the jaw (19a) has a threaded perforation where the auger screw (19) is also coupled, so that turning this one way or another, it is possible to loosen or tighten the jaw (19a) against the inner face of the flange (3).
    The support base (8) has pairs of facing windows (20) through which lower screws (21) are introduced in combination with slotted washers (22) and nuts (23) to fix the support base (8) to the respective flange (3) of the hollow structures (1) stacked, so that said lower screws (21) pass through perforations (3a) of the flange (3) and then ensure the lower fixation of the modular device by means of the nuts (23) corresponding threading on the lower screws (21).
