DESCRIPTION

5

OBJECT OF THE INVENTION

The present invention relates to a system of modular construction of structures, and specifically to constitution of the nodes defined therein, provided these

10 to allow different types of buildings, without discarding their application in furniture and in any other practical case in which a structure is required from which a construction of any kind based on tubular profiles can be built.

BACKGROUND OF THE INVENTION

15 Although there are modular constructions of structures, for buildings and other uses, however in some cases due to complexity and in others due to their lack of reliability, the truth is that the systems known so far do not fulfill their function effectively, that is, no allow the lifting of buildings with total security guarantees and

20 functionality

In addition, in modular structure construction systems, additional elements are always required for the formation of braces, for the formation of beams with a certain inclination, etc., all of which make the construction of the structure itself more expensive,

25 also requiring welding and other means to fix the different elements and parts involved.

In any case, there is no known system of modular construction of structures with the characteristics corresponding to that defined in this patent.

30 invention requested.

DESCRIPTION OF THE INVENTION

The system that is recommended, first of all presents the particularity of carrying out the construction of structures without the need for welding, and only by means of fasteners.

More specifically, the modular system is formed by grooved profiles, in some cases straight, in other cases at an angle, in other cases with lateral grooved formations, etc., to allow the union of tubular arms that will form beams, struts, braces, etc, where these arms are always connected to each other by means of screws that fix two corrugated parts of the profiles together, presenting these lateral wings with the holes for the passage of the fixing screws.

In addition, in certain cases, one of the lateral conformations of the corrugated profiles constitutes a means of articulated mounting for the end of arms that can form beams, and even struts and / or braces, with the possibility of allowing those tubular arms to be positioned with any angulation, and thus form sloping parts of the roof formation structure, form angle configurations in a dihedral shape on the roofs themselves or roofs, etc.

Therefore it is that the modular construction of structures is based on the conformation of nodes in which the determining tubular arms of the structure itself, whose tubular arms can form, as previously stated, struts or columns, beams , braces, etc. according to the arrangement in their concurrence with the knots.

Each knot will be formed by the grooved profiles, which in some cases will be continuous and are fixed to each other as a clamp by means of through screws through lateral through holes of those grooved profiles, while in other cases the profiles form an angle to each other, but always in the same piece for each profile, as well as presenting different sections according to the directions in the three axes X, Y, Z, or in T, in cross, etc.

The different configurations of the nodes allow two tubular arms to be positioned

contiguous, that is to say aligned longitudinally, or arrange two tubular arms forming an angle of 90º to each other, or form knots in which three arms perpendicular to each other concur along the X, Y, Z axes form knots in which four arms concur, which they can be fixed and perpendicular to each other, or two of them at an angle and the other two

5 articulated to form different angles of the respective tubular arms that join in an articulated manner to the respective profiles.

They can also form knots in which five arms perpendicular to each other, and even one or two of them articulated to form different angles.

10 Another feature of the system is that profiles can be arranged transversely to each other, by means of two corrugated profiles arranged in the opposite direction and with perpendicular orientation, to establish the cross-sectional arrangement of the two tubular arms that converge at that node.

15 It is also provided that the nodes can form an articulation or fixation element of the lower end of tubular arms determining columns or struts, that is to say for fixing on the ground by means of a plate on which the grooved profile in which articulates the end of the tubular arm constituting the strut or column.

20 Through all these variants of nodes, structures of a very diverse nature can be formed, that is to say with different configurations for buildings of all types, as well as for the formation of furniture, also of any type, etc.

25 Finally, to say that in all cases the parts or elements that participate in the nodes and in the fixation of the corresponding tubular arms, are only carried out by means of the use of screws, without the need for welding or any other element other than the profiles in one way or another to determine the corresponding nodes, and of the tubular arms themselves to form struts or columns, beams, braces, etc.

PREFERRED EMBODIMENT OF THE INVENTION

As can be seen in the aforementioned figures, the modular construction system of structures object of the invention is based on using a series of nodes with different configuration, which are used as joining elements of tubular arms (1) that together with the commented nodes will constitute the structure itself.

In this sense, in figure 1 it can be seen how the knot is formed by a pair of grooved profiles (2), which are straight and have lateral wings (3) with holes for

10 passage of corresponding tightening screws (4) to establish a kind of clamp between the two profiles (2) that are arranged facing each other by their grooves and between them the tubular arms (1) to be joined, so that as shown in the Figure 1 the knot formed by the two grooved profiles (2) facing each other, fix two tubular arms (1) aligned longitudinally with each other.

15 Figure 2 shows an angle knot for the union of two tubular arms (1), forming a right angle between them, for which the profiles, in this case referenced with (2a) are of angular configuration, at like its corresponding lateral wings (3), these being also provided with holes for the passage of the appropriate screws of

20 tighten (4) that both profiles (2a) will fix and tighten each other to hold and join the tubular arms (1) at right angles as seen in figure 2.

In figure 3 the fixing of the profiles (2b-2b ’) define three branches perpendicular to each other, according to the coordinate axes X, Y, Z, where the corresponding lateral wings (3)

25 are also affected by holes for the passage of the fixing and tightening screws (4) to achieve the securing and joining of three tubular arms (1) along the X, Y,

Z.

In all cases referred to as well as those that will be presented below, the

30 profiles (2, 2a, 2b, .....) will always be ribbed and will have their corresponding lateral wings (3) with their holes for the tightening and fixing screws (4) of the tubular arms (1) that They will form the structure.

In figure 4, another node is shown, like the one in figure 2, but in this case with a profile (2 ') welded by welding or by any other suitable means on the cross-sectional branch of the profile configuration (2a ), being that profile (2 ') forming a single piece body with one of the profiles (2a) and its groove facing outwards, to achieve the union of the end of a tubular arm (1) which in this case is assembled in an articulated way by means of the screw (4) that acts as a tilting axis of the tubular arm (1), allowing it to be positioned with any angulation with respect to the node formed by the profiles (2a).

A variant embodiment of Figure 4 is shown in Figure 5, so that in this case, instead of having a single profile (2 ') for assembly and articulation of a tubular arm (1), there are two ribbed profiles ( 2 '), in opposition and on one or the other of the transversal branches of the two profiles (2a), to establish an articulated mounting means of two tubular arms (1) opposite each other and articulated both to be able to occupy different positions, by what in this case according to figure 5, in the node four tubular arms (1) concur, two of them forming a right angle to each other and the other two, perpendicular to the previous ones but articulated to be able to occupy different angular positions.

Figure 6 shows three arms (1) joined in “T”, two of them aligned longitudinally on the clamp that form the profiles (2c), while the third one, which remains in vertical arrangement as shown in that figure 6 , is held by the clamp that form two ribbed profiles (2 '') that emerge from one of the side faces of the profiles (2c).

A variant embodiment of Figure 6 is shown in Figure 7, but incorporating a fourth tubular arm (1) perpendicular to the previous ones, for which it is provided that the cross-sectional branch of one of the profiles (2c) has a profile perpendicular (2 ') with outward groove, with facing holes for corresponding screw passage

(4) which constitutes the axis of rotation for the fourth tubular arm (1), allowing it to be positioned at any angle with respect to the knot formed by the other profiles (2c), in the concurrence of the three tubular arms (1) in “ T "

A variant embodiment of Figure 6 is shown in Figure 8, but with the concurrence

P201430865

01-09-2015

of four tubular arms (1) in the knot, three of them in “T” as shown in figure 6 and a quarter perpendicular to the previous ones, provided that the transverse branch of one of the corrugated profiles (2c) ) emerge another pair of profiles (2 '' ')

one free and the other fixed by welding to the profile (2c), forming the corresponding clamp in which the end of the fourth tubular arm (1), perpendicular to the previous ones, is fixed and fixed, by tightening the corresponding screws (4) over the holes of the wings (3) lateral to those profiles (2``).

In figure 9 another variant of embodiment is shown, in this case with a knot in which five tubular arms (1) concur, four of them like those of figure 8 and the fifth mounted on a grooved profile (2 ') in solidarity to the cross-sectional branch of one of the profiles (2c), where the tightening and fixing screw (4) constitutes the axis of rotation for that fifth tubular arm (1), this articulation being left and allowing to occupy different angular positions with respect to the knot , while the remaining four tubular arms (1) are fixed.

Figure 10 shows a knot in which two tubular arms (1) concurrently, but superimposed on each other, for which two straight grooved profiles are provided that can correspond to the configuration of the profiles (2), with a arrangement of confrontation of its grooves, but according to a transverse arrangement, to allow the superimposed and transverse arrangement between the tubular arms (1) that are held in an intermediate area thereof in the knot formed by those corrugated and straight profiles (2) .

A variant embodiment of Figure 10 is shown in figure 11, but in this case with two profiled profiles (2 ') opposed and forming 90 °, fixed by welding so that on these profiles (2') through screws ( 4) the corresponding tubular arms (1) are assembled in an articulated manner, thereby allowing the upper arm (1) to swing in one direction and another and form different angles with respect to the knot, contrary to what occurs in the realization of Figure 10 where the two tubular arms (1) are fixed.

An exemplary embodiment of a tubular arm (1) anchored to the

P201430865

01-09-2015

ground, through a plate (5) on which a grooved profile (2 ’) is joined with a hole in its lateral branches for the passage of a screw (4) as the axis of rotation of that strut

or tubular arm (1) while in figure 13 a knot formed by two ribbed profiles (2 ') is shown in opposition, one for mounting and fixing a tubular arm (1) and the other for articulated mounting of a second articulated arm (1).

Obviously, in addition to the examples described and shown in the drawings, very different configurations of knots and arrangement of tubular arms (1) could be obtained with respect to them, in some fixed cases, in other articulated cases, in other cases forming knots in the that concur 2, 3, 4, 5 and even more arms, etc.

In any case, based on the commented nodes and the assembly of the tubular arms (1), structures such as those shown in figures 14, 15 and 16 are obtained, among others, for example, so that the structure ( 6) shown in figure (14), includes tubular arms (1) in function of struts, tubular arms (1) in functions of upper structure, and even lower tubular arms in function of stiffening elements, and in all cases joined by concurrence of them in the corresponding nodes, referenced in this case with the number (7), although those nodes may correspond to that of figure 2, to that shown in figure 3, etc., these structures (6) being able to be used for construction of a cabin, for any building, etc.

The same applies to the structure shown in Figure 15, which includes struts (1) formed by the corresponding tubular arms, with knots anchored to the ground and with an upper part, and even with ends anchored to the wall, all for enable different configurations of buildings, furniture, etc.

Finally, Figure 16 shows a structure (8) with struts formed by tubular arms (1), knots (7) anchored to the ground, and an upper part forming two slopes, as well as transverse porches formed always and in all cases by the corresponding tubular arms (1) concurrent in the nodes (7), with the appropriate configuration in each case, so that in this case the structure (8) is suitable to form a building or construction whose cover will have two water or inclined planes
