IL41438A - Assembly of prefabricated concrete elements - Google Patents

Claims (2)

1. CLAIMS 1„ A assembly of pre abricated pre-stressed reinforced concrete elements, wherein each element' comprises reinforcing members solid with said element and subjected to predeter-' mined amounts of stress applied before the assembling of the elements, said assembly comprising a plurality of linking means rendering said assembly statically indeterminate through applying selectively to any reinforcement of an element supplemental stress independently of said predetermined stress, said linking means being respectively provided between any couple of said concrete elements, and each comprising : at least one cage associated with two nuts inside said cage(s), and at least two externally threaded parts inserted in said cage(s) and made solid with said elements, said nuts being screwed onto at least one of said parts while abutting against said cages by means of ball-and-socket bearing which v makes allowance for any misalignement of said elements, said nuts being further coupled respectively to said elements through said threaded parts.

2. An assembly according to claim 1, characterised in that said linking means. further comprises a metal plate anchored on said two reinforcements, one of said threaded parts being made solid with said plate. 3· An assembly according to claim 2, characterised in that said plate is directly screwed on one of said threaded parts. ¾. An assembly according to claim 2, characterised in that it comprises a bolt screwed in said plate ( 6 ) and a nut (10) embedded in the concrete and tightening said bolt, said plate being made solid with one of said threaded part by means of said bolt and last mentioned nut, and being embedded 41438/2 5. An assembly according to claims 1, 2, 3 or 4, characterised in that one of said threaded parts (C, fig. 1). forms one piece with said only one reinforcement. 6. An assembly according to claims 1, 2, 3 or 4, characterised in that one of said threaded parts is further; internally threaded and is screwed on said reinforcement. 7· An assembly according to claim 6, characterised in v that it further comprises a metal plate embedded in the concrete of said element and anchored to said reinforcement. 8. An assembly according to claims 1, 2, 3, 4, 5i 6 or 7, characterised in that n being equal to 1, said nuts are coupled to said elements directly through said threaded parts which are made integral respectively with said element 9· An assembly according to claims 1, 2, 3, 4, 5, 6 or 7, characterised in that n being equal to 2, one of said threaded parts is inserted in both said cages, said nuts being respectively mounted on the extremities of said last mentioned threaded part and being respectively coupled to ' said elements indirectly,, by means respectively of said cages, the two remaining threaded parts being screwed respectively in said cages.
