Embodiment Construction

[0022] refer to figure 1 , the sliding bearing according to the invention is generally indicated by the reference numeral 10 . The sliding bearing 10 comprises a first member 11 adapted to be connected to a supporting structure, such as a bridge pile P, and a second member 12 adapted to be connected to, for example, a girder G of a bridge superstructure.

[0023] Between the first member 11 and the second member 12 at least a pair of sliding surfaces 21 , 22 are arranged, the sliding surfaces being configured to allow movement and / or rotation between the first member 11 and the second member 12 of the support 10 .

[0024] In the described embodiment, the sliding bearing 10 is, for example, of the flat multidirectional type, ie provided with a flat sliding surface that allows a contact surface between the first member 11 and the second member 12 along a direction parallel to them. relative movement in any direction and / or relative rotation about an axis perpendicular to the c...

Abstract

The invention relates to a sliding bearing (10) for structural engineering applications comprising a first member (11) configured to be connected to a supporting structure (P), a second member (12) configured to be connected to an element (G) to be placed on said supporting structure (P), as well as at least one pair of sliding surfaces (21, 22) operably connected to said first and second members (11, 12) and configured so as to allow the first and second members to be moved and / or rotated relative to each other. One (22) of the sliding surfaces is made of a metal material, while the other sliding surface (21) is made of a low- friction polymer material. The low- friction polymer material is a cast polyamide 6 added with lubricants that are in the liquid state at temperatures in the order of 20°C and pressures in the order of 1000 hPa.

Description

technical field [0001] The present invention relates to a bearing arrangement for structural engineering applications, in particular a sliding bearing for civil structures such as bridges and buildings. Background technique [0002] Civil engineering structures typically employ supports that constrain two or more members of the structure. Bearings may form constraints, such as sliding, hinges, or a combination thereof, and allow relative movement between components of the structure, typically sliding movement or rotation during normal operation or in the event of an earthquake. [0003] A sliding bearing generally comprises at least one pair of flat or curved sliding surfaces that are slidable and / or rotatable relative to each other. One sliding surface is generally made of metal and mirror-finished, while the other sliding surface is made of a polymer material with a low coefficient of friction. Lubricants are often used to further reduce the coefficient of friction betwe...
