Connection Point For Metal Structure

Abstract

A connecting node for metallic structures, specifically for structures based on props or pillars ( 1 ) wherewith cross beams ( 2 ) are associated, wherein said pillars ( 1 ) incorporate rosettes ( 3 ) separated by a predetermined distance, each of which having a polygonal window ( 31 ) and at least one circular hole ( 32 ); while the beams ( 2 ) include on their edges a fork ( 4 ) having a stub ( 41 ) with a polygonal configuration that projects from the lower side and has a configuration equivalent to the window ( 31 ) and at least one hole ( 42 ) in correspondence with the hole ( 32 ) of the rosettes ( 3 ); the foregoing in anticipation that a fork ( 4 ) will be fitted into a pair of rosettes ( 3 ) without possibility of sideways movement of the beam ( 2 ) and, once the structure is assembled, that it will be immobilised by means of at least one screw ( 6 ) which, passing through holes ( 32 ) and ( 42 ), establishes the definitive connection.

1 . A connecting node for metallic structures, specifically for structures based on props or pillars ( 1 ) wherewith cross beams ( 2 ) are associated, wherein said pillars ( 1 ) include rosettes ( 3 ) for fixing the beams ( 2 ), while these include a fork ( 4 ) on the edges of their ends for fixing to the aforementioned rosettes, characterised in that it comprises:
 a pair of rosettes ( 3 ) fixed around the pillar ( 1 ) separated by a predetermined distance, each of which includes, at least on each side wherein a cross beam ( 2 ), a polygonal window ( 31 ) and at least one circular hole ( 32 ) are susceptibly fixed;   a C-shaped fork ( 4 ) fixed on each of the edges of the beams ( 2 ), the flanges of which are separated therebetween by a distance equivalent to that which separates the rosettes ( 3 ), each of which has a stub ( 41 ) having a polygonal configuration, which projects from the lower side and has a configuration equivalent to the window ( 31 ) of the rosettes ( 3 ) and at least one hole ( 42 ) in correspondence with the hole ( 32 ) of said rosettes;   
       the foregoing in anticipation that a C-shaped fork ( 4 ) will be fitted into a pair of rosettes ( 3 ), introducing and coupling the stubs ( 41 ) to the windows ( 31 ) thereof, without possibility of sideways movement of the beam ( 2 ) and that, upon assembling the structure, it will be immobilised by means of at least one screw ( 6 ) which, passing through the holes ( 32 ) and ( 42 ), establishes the definitive connection between the pair of rosettes ( 3 ) and the corresponding fork ( 4 ). 
     
     
         2 . The connecting node for metallic structures, according to  claim 1 , specifically for the connection between beams ( 2 ), joining the ends of certain beams with intermediate points of others, characterised in that it comprises:
 at the intermediate point of the beam ( 2 ) wherein the termination of a second beam will be fixed, it has a pair of rosettes ( 5 ) fixed at different heights separated by a predetermined distance, each of which incorporates, at least on each side wherein a cross beam ( 2 ), a polygonal window ( 51 ) and at least one circular hole ( 52 ) are susceptibly fixed;   a C-shaped fork ( 4 ) fixed to each of the edges of the beams ( 2 ), the flanges of which are separated therebetween by a distance equivalent to that which separates the rosettes ( 5 ), each of which has a stub ( 41 ) projecting towards the lower side having a polygonal configuration, equivalent to the window ( 51 ) of the rosettes ( 5 ) and at least one hole ( 42 ) in correspondence with the hole ( 52 ) of said rosettes;   
       the foregoing in anticipation that a fork ( 4 ) will be fitted into a pair of rosettes ( 5 ), introducing and coupling the stubs ( 41 ) to the windows ( 31 ) thereof, without possibility of sideways movement of the beam ( 2 ) and that, upon assembling the structure, it will be immobilised by means of at least one screw ( 6 ) which, passing through the holes ( 52 ) and ( 42 ), establishes the definitive connection between the pair of rosettes ( 3 ) and the corresponding fork ( 4 ). 
     
     
         3 . The connecting node for metallic structures, according to  claim 1 , characterised in that the windows ( 31 - 51 ) and projecting stubs ( 41 ) respectively have a rectangular cavity and cross-section. 
     
     
         4 . The connecting node for metallic structures, according to  claim 1 , characterised in that the holes ( 32 - 52 ) in the rosettes ( 3 - 5 ) and the holes ( 42 ) located on each C-shaped fork ( 4 ) are two and are respectively located on the sides of the window ( 31 ) and the stubs ( 41 ).
