Structural bearings - Part 7: Spherical and cylindrical PTFE bearings

Structural bearings - Part 7: Spherical and cylindrical PTFE bearings

This European Standard deals with the requirements for the design and manufacture of spherical and cylindrical PTFE bearings. The requirements and properties of the curved sliding surfaces are included in
EN 1337-2. Spherical and cylindrical bearings with an included angle 2 q > 60° and 2 q > 75° respectively are beyond the scope of this European Standard. (see Figure 6).
For the purpose of controlling the degree of freedom the bearings may be combined with flat sliding elements and guides according to EN 1337-2:2004 and restraining rings as per 6.3.4.
Cylindrical bearings are susceptible to unexpected moments about the transverse axis of the cylindrical surface.
Additional limitation of application to be taken into consideration is given in clause 1 of EN 1337-2:2004.

Lager im Bauwesen - Teil 7: Kalotten- und Zylinderlager mit PTFE

Diese Europäische Norm betrifft die Anforderungen an die Bemessung und die Herstellung von Kalotten- und Zylinderlagern mit PTFE. Die Anforderungen an und Eigenschaften von gekrümmten Gleitflächen sind in EN 1337-2:2004 geregelt. Kalottenlager mit einem Öffnungswinkel von 2 J > 60° und Zylinderlager mit 2 J > 75° liegen außerhalb des Anwendungsbereiches dieser Europäischen Norm (siehe Bild 6).
Zur Steuerung der Freiheitsgerade der Lagerung dürfen die Lager mit ebenen Gleitteilen und Führungen nach EN 1337-2:2004 und Arretierungsringen nach 6.3.4 kombiniert werden.
Zylinderlager sind gegen unplanmäßige Momente um die Querachse der zylindrischen Gleitfläche anfällig.
Zusätzliche in Betracht zu ziehende Anwendungsbegrenzungen sind in EN 1337-2:2004, Abschnitt 1 angegeben.

Appareils d'appui structuraux - Partie 7: Appareils d'appui cylindriques et sphériques comportant du PTFE

Le présent document européen traite des exigences relatives à la conception et à la fabrication des appareils d'appui cylindriques et sphériques comportant du PTFE . Les exigences et les propriétés se rapportant aux surfaces de glissement courbes sont décrites dans l'EN 1337-2. N'entrent pas dans le domaine d'application de la présente Norme européenne les appareils d'appui cylindriques et sphériques dont l'angle au centre (2 q ) de la surface de glissement est supérieur respectivement à 60° et à 75° (voir la Figure 6).
Dans le but de limiter le degré de liberté des appareils d'appui, il est possible de les combiner avec des éléments de glissement plans et des guides conformes à l'EN 1337-2:2004 et avec des butées annulaires conformes au 6.3.4.
Les appareils d'appui cylindriques sont sujets à des moments non prévus autour de l'axe transversal de la surface cylindrique.
Une limitation d'application supplémentaire à prendre en compte est donnée à l'Article 1 de l'EN 1337-2:2004.

Structural bearings - Part 5: Pot bearings
SIST EN 1337-5:2005

This part of EN 1337 specifies the requirements for the design and manufacture of pot bearings which will be used for operating temperatures between - 40 °C and 50 °C.
This part of EN 1337 does not apply to pot bearings made with other materials than those specified in clause 5.
Bearings which are subjected to rotation ad greater than 0,030 rad (see Figure 2) under the characteristic combination of actions or which incorporate elastomeric pads larger than 1500 mm in diameter are beyond the scope of this document.
Depending on the climatic region where the construction work is located the bearings can be designed to one of the following classes related to minimum operating temperatures (the minimum shade air temperatures): - 25 °C or - 40 °C.
When required to accommodate translational movements, pot bearings may be combined with sliding elements in accordance with EN 1337-2.
NOTE   The minimum shade air temperature for a location should be obtained from meteorological data appropriate to a 120 year return period. Consideration should be given to adjustment of this temperature for height and local divergence such as frost pockets and sheltered low-lying areas if the data obtained applies to a general area rather than to a specific location.

Structural bearings - Part 3: Elastomeric bearings
SIST EN 1337-3:2005

This part of EN 1337 applies to elastomeric bearings with or without complementary bearing devices to extend their field of use such as flat sliding elements covered by EN 1337-2 or sliding surface described in 4.4.4, as used in bridge structures or any other structure with comparable support conditions.
This part of EN 1337 applies to elastomeric bearings with dimensions in plan up to (1200 x 1200) mm and does not cover elastomeric bearings made with other elastomers materials than those specified in 4.4.1. It applies to laminated bearings types A, B, C, laminated sliding bearings types E and D, plain pad and strip bearings type F.
This part deals with bearings for use in operating temperatures ranging from - 25 °C to + 50 °C and for short periods up to + 70 °C.
It is recognised that the air temperature in some regions of Northern Europe is lower than -25 °C.
In this case of very low operating temperature (down to - 40 °C), it is essential that bearing characteristics comply also with the shear modulus at very low temperature (see 4.3.1.3. and annex F)

Structural Bearings - Part 10: Inspection and maintenance
SIST EN 1337-10:2003

This European Standard applies to the inspection and main-tenance of bearings designed in accord-ance with EN 1337-1, when used in the construction of bridges or struc-tures requiring similar bearing sys-tems. It presupposes the existence of guidelines for the regular inspection of the whole structure during its service life.
It may also be used as appropriate for the inspection and maintenance of bearings designed and/or installed before the intro-duction of this European Standard.
This European Standard specifies the aspects of each type of bearing that shall be inspected and recorded. It does not specify permissible values. For these reference shall be made to the relevant parts of this European Standard and to the drawings and design calculations for the bearing and the structure.
NOTE 1   Attention is drawn to the par-ticular necess-ity for regular inspection and main-ten-ance of bearings as, with-out such inspection and mainten-ance, premature failure may occur.
NOTE 2   National regulations may exist on the subjects covered by this European Standard and, therefore, they prevail on it.
