EXAMPLES OF CARRYING OUT THE INVENTION

With reference to figures 1 to 6, yes? shown a bracket 1a for connecting sections and/or panels and/or plates to a wall or to a substructure, for example for the construction of a roof or a wall of a building.

The bracket 1a comprises in detail a first plate 2 and at least one second plate 3 inclined or perpendicular to the first plate 2.

The first plate 2 ? flat, so that it presents main development in one floor.

Preferably, the first plate 2 has a length between about 80 mm and about 120 mm, a width between about 80 mm and about 120 mm as well as thickness between about 1.5 mm and about 5 mm.

The bracket 1a can? be made of any suitable material, metallic, for example steel, aluminum, etc., or even plastic.

The plates 2 and 3 could be obtained in one piece or a single piece, for example by molding or other suitable method. Alternatively, the plates 2, 3 could be obtained separately and then welded to each other.

Moreover, the first plate 2 delimits at least four first holes 4a-4d or slots passing at a distance from the center or center line of the first plate 2, with two first holes 4a, 4b or slots placed one on the opposite side of the other with respect to the center or center line of the first plate 2 or of a respective central hole and the other two first holes 4c, 4d or slots positioned opposite each other with respect to the center or center line of the first plate 2 or of a respective central hole.

Advantageously, the first two holes 4a, 4b or slots are aligned along a first direction and the other first two holes 4c, 4d or slots are aligned along a second inclined direction, for example between approximately 70? and about 110?, or orthogonal to the first direction.

Preferably, the first four holes 4a-4d or slots are arranged at the vertices of the same rhombus (ideally obtainable by joining these vertices), in particular a rhombus with diagonals of different sizes, therefore not a square.

With reference to this aspect, the rhombus configuration guarantees four fixing points which delimit an area considerably smaller than four fixing points arranged for example in a square or rectangle shape, if one takes into account the fact that the area of a rhombus? base times height divided by two.

In this regard, the first two holes 4a, 4b or slots aligned along a first direction are at a distance from each other (considering the distance between the respective centers or central zones), for example between about 60 mm and about 80 mm, while the other two first holes 4c, 4d or slots aligned along a second inclined direction are at a distance from each other (considering the distance between the respective centers or central zones), for example between about 60 mm and about 80 mm.

Moreover, the first plate 2 pu? be square or rectangular, if desired without edges or in any case with incomplete edges, in which case the two directions now indicated can each be parallel to a respective main side of the first plate 2.

Pi? in particular, according to the non-limiting embodiment illustrated in the figures, the first plate 2 defines recessed regions RZ in correspondence with one or each of its four corners.

With reference to this aspect, the first plate 2 can present an edge consisting of four main and straight sides, that is to say a first pair of first opposite and parallel sides 2a as well as? a second pair of opposite and parallel second sides 2b. In this regard, the edge of the first plate 2, in passing from each first side 2a to respective ends? of the second sides 2b first has a minor section 2c parallel to the second sides 2b and extending from the respective first side 2a towards the inside of the stirrup or towards the other first side 1a and then a minor section 2d parallel to the first sides 2a and ending in an? end? of a respective second side 2b, so that? a recessed zone RZ is defined between two adjacent and successive minor sections 2c and 2d.

If desired, the first holes 4a-4d or slots have a diameter between about 4 mm and about 8 mm or in any case an extension between about 12 mm<2 > and about 50 mm<2>, for example a diameter between about 5 and about 7 mm or width between about 19 mm<2 > and about 40 mm<2>.

The first plate 2 pu? then delimiting a through hole 5 or central slot, for example with a diameter or extension between 1.5 and 3 times that of the first holes or slots 4a-4d.

The central hole or slot 5 can? have a diameter between about 8 and about 16 mm or a width between about 50 mm<2 > and about 200 mm<2>, for example a diameter between about 11 and about 13 mm or a width between about 95 mm<2 > and about 130 mm< 2>.

If desired, the first holes 4a-4b are at a distance from the central hole or slot 5 of between about 30 and about 40 mm.

Advantageously, the first plate 2 also delimits at least four second holes 6a-6d or through slots of greater diameter or extension than the first holes 4a-4d or slots. The second holes or slots 6a-6d are each at or proximal to a respective vertex or corner of the first plate 2.

If desired, the second holes 6a-6d or slots have a diameter between about 8 mm and about 16 mm or extension between about 50 mm<2> and about 200 mm<2>, for example diameter between about 8 and about 10 mm or width between about 50 mm<2 >and about 80 mm<2>.

Advantageously, two second holes 6a, 6b or slots are provided positioned one on the opposite side to the other with respect to the center or center line of the first plate 2 or of a respective central hole 5 and the other two second holes 6c, 6d or slots positioned one from band opposite to the other with respect to the center or center line of the first plate 2 or of a respective central hole 5.

even more advantageously, two second holes or slots 6a, 6b are aligned along a third direction which ? inclined or orthogonal to the fourth direction of alignment of the other two second holes or slots 6c, 6d.

If desired, the second holes 6a-6b are at a distance from the central hole or slot 5 (considering the distance between the respective centers or central zones) of between about 35 and about 50 mm.

According to the non-limiting embodiment illustrated in the figures, four first holes 4a-4d are provided, each arranged at a respective vertex of a rhombus and two aligned along a direction parallel to a main side of the first plate 2 and the other two along a direction parallel to the other main side of the first plate 2, a central hole 5 and four second holes 6a-6d each arranged at a respective vertex of a square and two aligned along a direction inclined with respect to the main sides of the first plate 2 or one diagonal of the latter and the other two aligned along another direction inclined with respect to the main sides of the first plate 2 or another diagonal of the latter.

Basically, the first 4a-4d and the second 6a-6d holes or slots are angularly spaced from each other and lie in a circular crown with the center in the central hole or slot 3, so that? each second hole 6a-6d is arranged in a zone between two respective first adjacent and successive holes 4a-4d and vice versa. On merit? to this, in the passage on this circular crown between two first adjacent and successive holes 4a-4d one passes in the delimiting area of a respective second hole 6a-6d and vice versa.

With reference now to the at least one second plate 3, it extends from the edge of the first plate 2, for example from a respective straight side of the first plate 2. As indicated, the second plate? inclined, for example between 70? and 110?, or preferably orthogonal to the first plate 2.

The side walls 17b can then be connected to the second plates 3 by inserting screws or pins or dowels in holes or slots 7, 8 or 9 in the second plates 3 and in holes or slots 17c in the profile 17.

In this case, if the fins 10 are provided, pairs of fins 10 are spaced apart practically corresponding to the width of the profile 17, i.e. the distance between the side walls 17b of the same, so that the passage of the profile 17 through the bracket 1a is obtained by pushing the section 17 so? to elastically widen the tabs 10, which after this insertion phase will lock the profile 17 together.

The main wall 17a of the section 17 ? preferably inserted at a distance and not close to or adjacent to the first plate 2 of the bracket, since the profile is inserted preferably in the bracket 1a so that? the inner surface of the walls 17a, 17b of the section bar 17 faces the first plate 2 of the bracket 1a, 1b, 1c.

Clearly, the distance between the main wall of the section 17 and the first plate 2 is defined by the height or length of the side walls 17b.

? then a panel 18 is provided, for example a sandwich panel, connected on one side, in any way suitable to the section bar 17 or better to the main wall 17a of which and, on the other, for example at a respective sheet metal of the connected panel to another bracket 1a, if desired by means of respective screws or pins or dowels inserted in the holes or slots in the first plate 2, for example in one, two, three or four first holes 4a-4b.

For the insertion of the second profile 19 in a bracket 1a, 1b, 1c, the above applies with reference to the first profile 17.

As far as figures 14 and 15 are concerned, they illustrate the manufacturing phases of a building structure 15b similar to that of figures 12 and 13, but with the second profile 19 having a substantially vertical arrangement.

Figures 16 and 17, on the other hand, illustrate the construction phases of a building structure 15c similar to that of figures 12 and 13, but with the first profile 17 having a substantially vertical configuration and the second profile 19 having a substantially horizontal configuration.

Figures 18 and 19 then illustrate the construction phase of a building structure 15d similar to that of figures 12 and 13, but with both section members 17 and 19 having a substantially vertical arrangement.

How will you have it? way to make a stirrup 1a, 1b, 1c according to the present invention ? essentially universal, as it pu? be used for various applications, for example for connection to a wall or to a superstructure of panels, if desired sandwich to be mounted for example vertically or horizontally.

Bracket 1a, 1b or 1c can? moreover, it can be installed on existing panels as well as for the assembly of profiles, even of different types, to be assembled with the desired configurations, horizontal, vertical or even inclined with respect to the horizontal and vertical.

This bracket then guarantees a? High flexibility? design, being in fact able to adapt different components and adjust the respective position on site as desired.

? thanks to a bracket 1a, 1b or 1c, a single adjustment of the out of plumb is possible, for example thanks to the slots 12.

In this regard, the first holes 4a-4d can be provided in particular for fastening to panels.

The second holes 6a-6d, on the other hand, if provided, can be provided in particular for fixing by means of dowels to an existing masonry.

The central hole 5 can? be used for example to allow fastening to a substructure.

As regards the assembly of a connection bracket 1a, 1b or 1c between profiles and a panel installed vertically or horizontally, one could for example opt for:

- a fastening both to the external sheet of the panel, by means of respective screws or pins or dowels inserted in two or four first holes 4a-4d, and to the sections by means of respective screws or pins or dowels inserted in the central hole 5 and/or in one or more ? of the second holes 6a-6d, or

- a fastening to the external sheet metal of the panel only, by means of respective screws or pins or dowels inserted in two or four first holes 4a-4d; in this case, part of the profile would be inserted into the bracket and, if desired, secured to it by means of respective screws or pins or dowels inserted in holes or slots in the second plates or, if provided, in the third plates.

Moreover, on a bracket 1a, 1b or 1c it is possible to install L, T or C shaped profiles, for example in metal, such as steel, on which it can subsequently be installed, for example a cladding.

Moreover, special profiles can also be installed on a bracket 1a, 1b or 1c for installing composite or stoneware.

Will you understand? therefore that a bracket according to the present invention guarantees high flexibility? of installation and allows the fixing to the wall and/or on vertical panels and/or on horizontal panels and/or for the vertical assembly of profiles and/or for the horizontal assembly of profiles.

Modifications and variations of the invention are possible within the scope of protection defined by the claims.
