Description

[0017] The invention is described below based on an embodiment thereof and with reference to the attached figures, in which:

[0018] FIG. 1: a schematic perspective view of first device of the fixing system.

[0019] FIG. 2: a schematic perspective view of second device of the fixing system.

[0020] FIG. 3: a schematic view of an example of arrangement of the fixing system on one side of a construction module.

[0021] FIG. 4: a schematic view of the application of the system of the invention to an illustrative construction module.

[0022] As mentioned above, the system of the invention is formed based on first fixing devices and second fixing devices, first fixing devices to be embedded in lateral sides of construction modules and second fixing devices in corners of said modules.

[0023] As shown in FIG. 1, a first fixing device (1) is made up of two pairs of rigid rods, an outer pair (11) and an inner pair (12).

[0024] Each pair of rods is then made up of two rods, one lower rod and one upper rod, arranged vertically one above the other, and both folded defining a U-shape, both pairs of rods (11, 12) being arranged concentrically relative to each other. As can be seen in this figure, the pairs of rods define also a U-shaped hole. This hole has at least one boss (3), preferably four bosses (3), for the passage of two fixing screws (not shown).

[0025] In the case of one boss, this is arranged on the longitudinal axis defined by inner rods (12).

[0026] In the preferred embodiment with four bosses, two of these bosses (3) are arranged in this U-shaped hole in correspondence with apexes of the base of the U defined by the pair of outer rods (11), while the other two bosses (3) are arranged in arms of U-shaped hole spaced from the first, in the folding area of the pair of inner rods (12), the four bosses defining apexes of a square.

[0027] Second fixing device (2), shown in FIG. 2, is made up in this case of three pairs of rigid rods (21, 22, 23), an outer pair (21) and two inner pairs (22, 23), each pair also made up of two rods, one lower rod and one upper rod, arranged vertically one above the other.

[0028] One pair of rods (21) is shaped defining a right-angle, while the other two pairs of rods (22, 23) are shaped defining equal acute angles and are arranged symmetrically and equidistant with respect to angle bisector of the pair of outer rods (21), thus defining a hole in an arrowhead shape.

[0029] As in the device described above (1), this arrowhead hole houses at least one boss (3), preferably four bosses (3).

[0030] In the case of one boss, it is arranged in the inner angle of outer rods pair (21).

[0031] In the preferred embodiment with four bosses (3), one of them is arranged in inner angle of outer pair of rods (21) and the other three in correspondence with apexes of outer acute angles defined by outer pairs of rods (22, 23), the four bosses (3) defining apexes of a square, for the passage of corresponding fixing screws (not shown).

[0032] As shown in figures, bosses (3) include perimeter circular flanges in their lower and upper part extending over lower and upper surfaces defined by pairs of rods in order to facilitate threading of fixing screws once fixing devices are embedded in sides and corners of construction modules.

[0033] As seen in FIG. 3, where an example of the fixing system arrangement is shown on one construction module side, in order to provide integrity to fixing devices once they are embedded in their locations on said construction module side, system of the invention provides metal plates (4) equipped with four through holes defining a square and in correspondence with perimeter circular flanges of bosses (3) of fixing devices (1) and (2), plates (4) being arranged at the level of outer and inner surfaces of module side.

[0034] In a preferred embodiment, the aforementioned rigid rods are made of galvanized or corrugated steel to ensure bending and corrosion resistance of the same.

[0035] Likewise, in another preferred embodiment, bosses (3) are fixed to rigid rods at their contact points by welding.

EXAMPLES

[0036] The following example illustrates the application of the system of the invention to a four-sided construction module.

[0037] FIG. 4 shows this example of application to a four-sided construction module constituting a hollow cube where two adjacent sides sharing a common ridge have been eliminated.

[0038] FIG. 4a shows arrangement of fixing devices (1, 2) for upper and lower sides and in FIG. 4b for lateral sides.

[0039] Thus, in this example, fixing devices (1) are used arranged at the semi-ridges of sides, in this case four devices (1) for each side, and fixing devices (2) at apexes of each side.

[0040] From above description of the fastening system, following advantages, among others, are derived:

[0041] Fixing devices act as loading and unloading elements and are ideal for carrying out a precision assembly, additionally facilitating the accommodation of temporary or permanent devices, self-assembly and subsequent maintenance.

[0042] On the other hand, the system of the invention allows easier exchange of damaged or deteriorated elements in structures, as well as promote fixing of modular elements intended for interior modulation.

[0043] Likewise, the system of the invention provides construction structures that comprise it with the ability to increase and decrease, thanks to the possibility of exchanging and sizing construction elements that are part of them and that transmit intervening loads, elements such as pillars, slabs, walls, etc., forming complex definitive structures.
