Abstract

Abstract The present invention relates to a spheric cap bearing device for safely connecting elements of bridges, viaducts, buildings and the like, which comprises a bottom element, in which there is provided a recess in which is engaged a spheric cap coupling element the bottom of which is slidably supported on the bottom of the recess. At the top of the bottom element there is arranged a top element provided, on the bottom side thereof, with a concave recess mating with the spheric surface of the coupling element.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 73 words
A spheric cap bearing device for safely connecting elements of bridges, viaducts, and buildings, characterized in that said bearing device comprises a bottom element, in which is defined a recess engaging therein a spheric cap coupling element, said coupling element having a bottom slidably bearing on the bottom of said recess and a top element having, on a lower side thereof, a concave recess mating with a spheric surface of said coupling element.
Claim 2
Dependent Claim 73 words
A spheric cap bearing device for safely connecting elements of bridges, viaducts, and buildings, characterized in that said bearing device comprises a bottom element, in which is defined a recess engaging therein a spheric cap coupling element, said coupling element having a bottom slidably bearing on the bottom of said recess and a top element having, on a lower side thereof, a concave recess mating with a spheric surface of said coupling element.
Claim 3
Dependent Claim 31 words
A spheric cap bearing device, according to claim 1, characterized in that the bottom of the coupling element and the bottom of the recess are coated by a low friction material.
Claim 4
Dependent Claim 49 words
A spheric cap bearing device, according to claim 1, characterized in that said recess has a substantially open-top cylindric shape, and in that the top element is provided, on a lower face thereof, with an extension in which there is defined said recess, said extension projecting in said recess.
Claim 5
Dependent Claim 44 words
A spheric cap bearing device, according to claim 1, characterized in that said bearing device further comprises an annular element, coaxially engaged in said recess, against the cylindric side wall of said recess, said extension of said top element projecting in said annular element.
Claim 6
Dependent Claim 31 words
A spheric cap bearing device, according to claim 4, characterized in that said annular element is provided with surfaces contacting said bottom element which surfaces are coated by a dielectric material.
Claim 7
Dependent Claim 23 words
A spheric cap bearing device, according to claim 1, characterized in that said device comprises slidable coupling surfaces coated by an anti-friction material.
Claim 8
Dependent Claim 23 words
A spheric cap bearing device, according to claim 6, characterized in that said slidable coupling surfaces are coated by a dielectric anti-friction material.
Claim 9
Dependent Claim 35 words
A spheric cap bearing device, according to claim 1, characterized in that said top element comprises a plate, overlying said extension, and slidably associated with said extension, along a cross direction of the recess axis.
