Abstract
Description
- The present invention concerns metal joints for assembling beam elements to create geodetic or spatial structures, in particular of the type comprising laminated or solid wooden beams.
- Among prefabricated building structures a very important part is played by structures consisting of rods arranged according to surface geodetics, owing to the different fields of application to which they lend themselves, such as, for instance, coverings for large structures (industrial, civil, sports installations etc.).
- In large prefabricated structures, however, apart from the problems connected with overall design, there exists a series of problems of the parts, which includes organization of the joints to carry out assembly of different parts produced to form a single body.
- The object of the present invention is to provide an easy, safe and simple manner of joining the single laminated or solid wood rods making up geodetic or spatial structures, by use of metal joints.
- A further object is to create a joint that in no way spoils the aesthetics of the structure or causes weakening of the wooden parts due to the holes necessary for fixing bolts.
- The object has been achieved by creating a multi-hinged metal joint consisting of a central body provided with a supporting base such as to create a support for the ends of the laminated or solid wood beams and an upper connection for fixing said end of each beam which is shaped so that it can be fixed to said connection.
- A preferred embodiment provides for a hollow polygonal or even circular body, the inner cavity of which is stiffened with special reinforcements.
- The connection may be in particular a projection for fixing the ends of the beams; if the body is hollow this projection can be simply an extension of the side wall of the polygonal or even cylindrical body.
- In particular this extension may be provided with holes to allow fixing, by means of bolts, of a connecting support that is made fast to the beams by nailing. Said holes in at least one of the parts forming the connection are preferably ovalized.
- A preferred embodiment also provides for radial wings, which demarcate the space reserved for each single beam, these also equipped with connections, in particular holes.
- The structural assembly according to the present invention comprises the above described joints and laminated or solid wood beams, the supporting ends of which can be tapered and provided with a metal element to complete the joint. This completing element is formed by a plate and an end part equipped with connections matching those on the central body, for example holes for the clamping bolts. The wooden beams are nailed to the metal plate which thus forms an upper end connection.
- The joint according to the present invention permits safe and easy joining of the various beams which, arranged along the surface geodetics, make up the covering framework.
- A further aesthetic advantage lies in the fact that no bolts or fixing assemblies such as brackets are visible on the inside of the structure, the nails that make the metal element fast to the beam being situated on the extrados of the covering.
- A preferred but not restrictive embodiment, relative in its size and number of assembled beams to a certain covering, of a joint according to the present invention is illustrated in the accompanying drawings in which:
- fig. 1 shows an exploded top view in reduced scale of a joint with a cylindrical central body;
- fig. 2 shows a side view, again in reduced scale, of the joint, partly cutaway along the line 2-2 of fig. 1, in which the wooden beam has been eliminated for greater clarity;
- fig. 3 shows a cross-section similar to that in fig. 2, but in reduced scale and in use;
- fig. 4 shows a bottom view on the left and a top view on the right of the joint in use.
- Figures 1 and 2 show the
joint 1 consisting of a hollowcylindrical body 10 equipped withreinforcements 11. Anupper projection 15 is equipped withholes 7 for connection to a completingelement 2 of the joint attached to the end of the laminated orsolid beam 9. Thisbeam 9 rests on thebase 8 of thebody 10 between theradial wings 5 provided in saidbody 10. In theend part 3 of completingelement 2 threeoval holes 6 are disposed to allow fastening by means of bolts to cylindricalcentral body 10.Holes 7 are also provided on thewings 5 to accomplish assembly of thebeam 9.Number 4 designates the metal plate that is joined by nailing (nails 12) to thebeam 9. - Figure 2 shows more clearly how the two parts making up the joint are joined together. The supporting
base 8 is integral with the bottom part of thebody 10 and forms a circular shelf, on which thebeams 9 rest. These are fastened to the base by means of nails 13 (figure 4). - Figure 3 shows a cross-section of the joint in use, in which the joining means between the various parts can be seen.
- In the top view the
plates 4 fixed by thenails 12 to the laminatedwood beams 9 are visible. The fastening of thewings 5 to twoadjacent end parts 3 can also be seen, as well as the fastening of the latter to theupper projection 15 of thecylindrical body 10 by means of bolts and relative washers. In the bottom view thebeams 9 can be seen fastened by nailing (nails 13) to thebase 8 extending from the bottom surface ofcylindrical body 10. - As will be noted from the above, no bolts pass through the wood as this would weaken it.
