Problems solved by technology

Also, polyamide becomes harder at low temperatures and is characterized by a more pronounced loss of viscoelasticity compared to PTFE, so it is not suitable for use at low temperatures

Embodiment Construction

[0045] refer to figure 1 , the sliding bearing according to the invention is generally indicated by reference numeral 110 . The slide bearing 110 comprises a first part 111 and a second part 112 operatively connected to each other and configured to bear longitudinal loads.

[0046] The first part 111 is intended to be connected to a supporting structure, such as a mass bridge or the foundation of a building or an industrial plant, and the second part is configured to be connected to an element intended to be placed on said supporting structure, such as a bridge deck or a building or industrial plant. Beams of an industrial plant. In the embodiment shown, the connection of the bearing parts connected to the support structure to the elements is achieved for example by special feet or posts 131 , 132 intended to fit and fix in holes formed on these parts.

[0047] Bearing 110 also includes at least one pair of sliding surfaces disposed between the first and second components to...

Abstract

The invention relates to a sliding bearing (110; 210; 310) for construction, said bearing (110; 210; 310) comprising at least a first and a first Two parts (111; 112; 211, 212, 213; 311, 312, 313) and at least one pair of sliding surfaces (121, 122; 221, 222, 223, 224; 321, 322, 323, 324) arranged between said first and second parts to allow mutual movement and / or rotation thereof. One of said pair of sliding surfaces (121; 221, 223; 321, 323) is a plate made of polymer material mounted on one of said first and second parts, and the other sliding surface (122 ; 222,224; 322,324) is a metal surface associated to at least part of the face facing the other element of the polymer material sheet. The polymer material plate is made of polytetrafluoroethylene (PTFE) modified by adding perfluoropropyl vinyl ether (PPVE) in percentages between 0.1% and 0.3% by weight.

Description

technical field [0001] The present invention relates generally to supports for construction and more particularly to a sliding bearing for construction such as bridges and buildings. Background technique [0002] In the construction of civil and industrial buildings as well as road infrastructure such as bridges, road and railway viaducts, plain bearings are commonly used which define two or more components in a structural slide or hinge constraint, as well as combinations thereof. Plain bearings are used to allow relative motion, usually translation and / or rotation, between components in a structure. Under normal operating conditions, relative motion is caused by the weight of the building, shrinkage of the building materials, thermal effects, and forces resulting from transportation, wind, and normal use of the building. Motion can also occur under abnormal conditions, such as in the case of seismic events. [0003] Plain bearings generally comprise at least one first an...
