Pieces for modular construction, that allow the construction of greenhouses both for industrial and domestic use, as well as of any type of construction, adaptable to any form and size, for which the longitudinal piece has some longitudinal channels (1), and on each circular ends (2) and (3), one female (2) and another male (3), wherein both have some perforations (4) and (5), while the end (3) has some truncated conical nipples (7) and the end (2) has some complementary truncated conical perforations (6). For curved constructions the longitudinal pieces are joined by means of a piece (8) which likewise has some channels (9), a central perforation (10) and other perforations (11), as well as truncated conical perforations (12) and (13).
1. Pieces for modular constructions, characterised in that they allow the construction of greenhouses both for industrial and domestic use, as well as of garages, box rooms and whatever construction, it being possible to adapt to any form and size, wherein for the construction thereof a longitudinal piece is used, which has along its full length some channels (1) in which are displaced the blinds or enclosing elements that can be wooden panels, polycarbonate sheets, etc., moreover said pieces have some circular ends, one male (3) and another female (2), wherein both have a central perforation (4) and others for joining (5), whilst the male end (3) has some truncated conical nipples (7), and the female end (2) has some complementary truncated conical perforations (6); moreover the joining piece (8) for curved constructions is mounted between two longitudinal lengths, is wedge-shaped in profile, having likewise some channels (9), a central perforation (10), coincident with the perforation (4) and individual perforations (11) for the purpose of achieving a perfect union between pieces, as well as some truncated conical perforations (12) and (13).
 In the light of the aforementioned figures, a description is provided hereafter of a manner of preferred embodiment of the invention as well as the explanation of the drawings.
 In FIG. 1 it can be observed how the longitudinal piece has individual channels (1) along its full length wherein are displaced the blinds or enclosing elements, like polycarbonate sheets, having on the ends of the piece some ends, one of them female (2) and the other male (3).
 Both circular ends (2) and (3) of the longitudinal piece, have a central perforation (4) with the object of favouring the union with other consecutive pieces. Equally on said circular ends (2) and (3) there are other perforations (5) also for the purpose of joining consecutive pieces.
 On the male end (3) there are some nipples (7) of truncated conical shape, whilst on the female end (2) some complementary truncated conical perforations (6) are provided in order to favour the union of consecutive modular pieces.
 In FIG. 2 it can be observed how the joining piece (8) for curved constructions, has some channels (9) in which the blinds are displaced, likewise it has a central perforation (10), coincident with the perforation (4), implemented on the circular ends (2) and (3), also it has some perforations (11) coincident with the perforations (5) of the circular ends (2) and (3) and finally some perforations (12) and (13) are observed that are of truncated conical shape for housing the nipples (7) of the male end (3). Said perforations (12) and (13), the depth thereof, logically depends on the side where they are on of the joining piece (8), since this piece is wedge-shaped in profile.
 It is not considered necessary to extend this description further for any expert in the matter to understand the scope of the invention and the benefits deriving therefrom.
 The materials, form, size and mounting of the elements will be capable of variation provided they do not alter the essential nature of the invention.
 The terms in which this descriptive specification has been expressed must always be taken in their broadest sense and not restrictively.
 To complete the description that will be given below and with the object of assisting in a better understanding of its properties, the present specification is accompanied with a set of drawings in the figures of which, by way of illustration and not restrictively, the most significant details in the invention are represented.
FIG. 1. Shows a representation in perspective of the longitudinal piece for the modular construction.
FIG. 2. Shows a representation of the piece used as union between two consecutive pieces, for the erection of curved constructions, as well as the mounting of the longitudinal pieces.
 The object of the present invention is some pieces for modular constructions, such that they permit the erection of huts, greenhouses, garages, box rooms, etc.
 The assembling of the pieces to each other permits the erection of said modular constructions, it being possible to adopt diverse forms, serving as a basis for the mounting of enclosing elements, fastening and retaining them in a secure and effective way.
 The present pieces for modular construction are characterised in their special configuration such that it allows the retention of the enclosing pieces as well as the assembling with other pieces in an effective and secure way, achieving a structure with a sufficient self-supporting capacity and rigidity.
 Thus the present invention lies within the ambit of modular constructions, and more specifically those of greenhouses, dog kennels, garages, etc., using for these some structural elements like those that are described below.
 Up till now the construction of greenhouses is carried out by means of tubular or supporting elements joined with each other by means of additional pieces, said supporting pieces not having structural properties that facilitate the mounting and fastening of enclosing elements, requiring additional means for enclosing or fastening. Said constructions are also limited by the dimensions of said supporting elements, it not being possible to configure different structures adapted to different situations.
 Therefore it is an objective of the present invention, to overcome the above drawbacks, by developing for this a series of pieces that allow the erection of any type of construction, the construction not being limited by the pieces themselves, and that these offer some structural properties that allow easy mounting of the enclosing elements of the constructions.
 The proposed invention of pieces for modular construction, consists of a series of pieces, which are joined to each other and that by addition of similar pieces the erection of any type of construction is achieved. Also, through the use of pieces that are wedge-shaped and that are mounted between two modular pieces, it is possible to obtain curved forms.
 One of the pieces is longitudinal in form with circular ends designed in a complementary way that allows the union with similar pieces to be obtained. The longitudinal piece, has over its length some such channels, on which are mounted the enclosing elements. Said enclosing elements can be blinds, sheets of polycarbonate or other materials. The material of implementation of the longitudinal pieces can be aluminium or any other, be this PVC, plastics, etc.
 The advantage that the present pieces offer, given their modular properties and appropriate dimensions, is the possibility to erect from industrial greenhouses, to greenhouses for domestic use, it being possible to have diverse and varied forms of use.
 The longitudinal piece, presents over its length, on both sides, an individual channel, which serves to fasten and secure the enclosing elements, which as has already been mentioned, can be from a blind, to a polycarbonate sheet. Moreover, said piece on the ends presents some circular projections with the objective of favouring the union with the rest of modular pieces. The circular ends are complementary, since whilst in one of them some conical nipples are mounted, in the other of the circular ends there are some perforations in truncated conical form, wherein the aforementioned nipples fit, in order to favour the union between adjoining pieces.
 The advantage that the modular construction offers is that of being able to adapt the construction to the size that is wanted, it being possible to adapt to any form or size.
 In order to be able to erect structures with curved forms, another piece has been designed of plastic or of similar material, wedge-shaped, in which there is a series of perforations, coincident with those of the circular ends of the longitudinal pieces.
