Disclosed is a finger joint having a bridging cover plate, which enables a steel plate having a thickness much smaller than that of a conventional finger to be used and allows the vertical rotation of an upper bridge structure. The finger joint includes: a bridging cover plate installed on a first structure and supported to a second structure across a gap so as to support a load of a vehicle passing over the gap, and configured to allow relative movement between the first structure and the second structure in a direction in which the distance of the gap changes; a first finger unit connected to the bridging cover plate; and a second finger unit installed on the second structure so as to allow relative movement relative to the first finger unit in a direction in which the distance of the gap changes.

A high-damping rubber isolation bearing, an intelligent bearing and a bearing monitoring system are disclosed. The high-damping rubber isolation bearing comprises a top bearing plate, a bottom bearing plate, a high-damping rubber bearing body and a base plate, wherein at least one pressure sensing unit is arranged between the top bearing plate and the base plate, or between the bottom bearing plate and the base plate. The intelligent bearing includes a data acquisition unit, a data output unit and the high-damping rubber isolation bearing. The data acquisition unit transmits the bearing pressure measured by the at least one pressure sensing unit to the data output unit. The bearing monitoring system includes a data acquisition unit, a data output unit, a monitoring center and the high-damping rubber isolation bearing.

A sliding bearing, arranged for supporting civil or structural engineering works, such as for example bridges or buildings, seismically isolated or not, where the bearing comprises A) a base (3) and an upper support (5); B) a sliding element (7, 7) interposed between the base (3) and the upper support, and against which the base (3) and the upper support rest. The sliding element (7, 7) comprises at least one layer (11, 11, 11, 11.sup.III) made of a sliding material (9) comprising in turn B.1) a content by weight equal to or greater than 50% wt of one or more fluorinated polymers; B.2 a content by weight comprised between 1-20% wt of boron nitride in hexagonal form. The mechanical properties of the sliding material (9) for use as a structural bearing or an anti-seismic isolator, are less sensitive to a temperature and environmental humidity with respect to known sliding materials.

A movable and dynamic work after construction linking two points separated by a natural or man-made obstacle, allows the permanent crossing of this obstacle. The work includes a deformable apron (1) which extends between said two points. The work comprises a set of elongated elements (2, 3). An assembly of several pairs of elements (2, 3) is disposed along the apron (1). The work comprises drive means (8) disposed at one end or at both ends of said work for adjusting the apron (1) lengthwise. The drive means (8) are arranged so that, when the means (8) are actuated, they drive the assembly of the pairs of elements (2, 3), so as to bulge the central portion of the apron (1) when the means (8) are actuated.
