Abstract
Assembly of prefabricated pre-stressed reinforced concrete elements solid with their reinforcements comprising linking means including at least one internally threaded cage, nuts in said cage, mounted on externally threaded parts directly or indirectly rigidly coupled to the reinforcements; the nuts abut against the cages by means of ball-and-socket bearings, thus making allowance for any misalignments of the elements. The reinforcements being solid with the concrete, this linking means affords for supplemental adjustment stress in particular elements only, whereby the assembly may be rendered statically indeterminate.
Claims8
An assembly of prefabricated pre-stressed reinforced concrete elements, wherein each element comprises reinforcing members solid with said element and subjected to predetermined 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:
- a first and a second cages (3a, 3b, FIG. 3), each cage having opposite opened-ends, a first externally threaded rod made integral with one of said elements of said couple and threaded into said first cage, a second externally threaded rod made integral with the other one of said elements of said couple and threaded into said second cage, a third rod having a first and a second externally threaded extremities respectively inserted in opened ends of said first and second cages, and a first and second nuts screwed respectively in said cages onto said first and second extremities and abutting respectively against said cages by means of ball-and-socket bearings.
An assembly of prefabricated pre-stressed reinforced concrete elements, wherein each element comprises reinforcing members solid with said element and subjected to predetermined 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:
- a cage (B;
- FIG. 1) having opposite opened ends, a first and a second externally threaded rods (C, D) inserted respectively in said ends, and respectively made integral with the respective elements of said couple, and two nuts respectively mounted on said rods, in said cages, said nuts abutting against said cages by means of ball-and-socket bearings.
