Structural bearings - Guide Bearings and Restraint Bearings
This Part of this European Standard deals with the requirements for the design and manufacture of Guide Bearings and Restraint Bearings.
Guide Bearings and Restraint Bearings are not intended to transmit vertical loads but they may be combined in one unit with bearings in accordance. EN 1337-1:2000, Table 1.
NOTE 1 Guide Bearings and Restraint Bearings are shown in EN 1337-1:2000, Table 1, No. 8.1 and 8.2. For combined bearings see EN 1337-1:2000, Table 1, bearing Nos. 1.2, 1.3, 1.6, 1.7, 1.8., 3.1, 4.1, 4.2, 4.3, 7.1, 7.3, and 7.4 with restraints and Nos. 1.5, 1.7, 2.2, 3.3, 3.4, 5.2, 6.2 and 7.3 with guides.
NOTE 2 Examples of combined bearings are given in Annex B.
The minimum operating temperature depends on the materials’ properties used at the required temperature and the limitations given in the referenced parts of this European Standard.
NOTE 3 In certain circumstances the bearings described in this part of this European Standard may be required to operate in a plane inclined to the horizontal. In such circumstances the terms "vertical" and "horizontal" should be interpreted appropriately.
Lager im Bauwesen - Teil 8: Führungslager und Festhaltekonstruktionen
Dieser Teil dieser Europäischen Norm befasst sich mit den Anforderungen an die Bemessung und Herstellung von Führungslagern und Festhaltekonstruktionen.
Führungslager und Festhaltekonstruktionen sollen keine vertikalen Lasten übertragen, aber sie können in einer Einheit mit Lagern nach EN 1337-1:2000, Tabelle 1, kombiniert werden.
ANMERKUNG 1 Führungslager und Festhaltekonstruktionen sind in EN 1337-1:2000, Tabelle 1, Nr. 8.1 und 8.2 dargestellt. Für kombinierte Lager siehe EN 1337-1:2000, Tabelle 1, Lager Nr 1.2, 1.3, 1.6, 1.7, 1.8, 3.1, 4.1, 4.2, 4.3, 7.1, 7.3, und 7.4 mit Festhaltekonstruktionen und Nr 1.5, 1.7, 2.2, 3.3, 3.4, 5.2, 6.2, und 7.3 mit Führungen.
ANMERKUNG 2 Beispiele für kombinierte Lager sind in Anhang B angegeben.
Die niedrigste Betriebstemperatur hängt von den Eigenschaften der bei der geforderten Temperatur verwendeten Materialien sowie von den Einschränkungen, die in den in Bezug genommenen Teilen dieser Europäischen Norm genannt werden, ab.
ANMERKUNG 3 Unter bestimmten Umständen kann von den in diesem Teil dieser Europäischen Norm beschriebenen Lagern gefordert werden, in einer gegenüber der Horizontalen geneigten Ebene zu wirken. Unter solchen Umständen sollten die Begriffe „vertikal“ und „horizontal“ passend interpretiert werden.

Composite Material PTFE Polytetrafluoroethylene 4 Functional Requirements 4.1 General Guide bearings and restraint bearings shall be designed to: transmit horizontal forces; allow vertical movements; allow movements in one or no horizontal directions; allow rotations; generate low resistance to movement; have durability appropriate to their intended use. NOTE As a consequence of the above these devices do not transmit applied vertical loads and bending moments.
Welding materials shall comply with prEN 1090-2. 5.5 Anchors Steel for shear studs shall have a guaranteed yield stress of not less than 340 N/mm2. Dowels and shear bars shall meet the requirements of sub-clause 5.2 and shall be fixed by welding or by bolts. 6 Design Rules 6.1 General The design values of the effects (forces, deformations, movements) from the actions at the supports of the structure shall be calculated from the relevant combination of actions according to EN 1990 and sections from 2 to 6 inclusive of both Parts 1 and 2 of EN 1991. NOTE 1 Until rules for the combination of actions for bearings become available in EN 1990, the guidance given in EN 1993-2 should be used.
The various elements of guide bearings and restraint bearings shall be designed in accordance with the relevant Eurocodes or the other relevant parts of this European Standard. NOTE 2 For the design of steel
parts see EN 1993. NOTE 3 For composite material see also EN 1337–2:2004, sub-clause 6.3. For the design of rotational elements Parts 3, 5 (6.2.3 and 6.2.4), 6 and 7 of this European Standard shall be applied, as appropriate. Guides shall be designed in accordance with EN 1337-2.
The movement capacity shall be verified by geometrical analysis under the fundamental combination of actions. The horizontal movement capacity shall be increased by the values given in EN 1337-1:2000, sub-clause 5.4. The vertical design movement capacity shall be at least the following: 15 mm upwards; 10 mm downwards. For the design of the combined units (see 1 Scope) the Part of this European Standard relevant to the device that transmits the vertical load shall be applied. 6.2 Rotational Elements Contact surfaces in rotational elements with steel - to - steel contact shall be machined to a surface roughness RY5i ≤ 6,3 µm in accordance with ISO 4587. In this case the friction coefficient shall be taken as 0,6. The combination of the materials in contact shall be such as to avoid cold welding. NOTE
Cold welding may be avoided by using the design rules given in EN 1337–5:2005 clause 6.2.3. Notice lubrication and dust protection of the contact zone. 6.3 Minimum plate thickness If used, the minimum thickness t of bearing plates and of anchor plates shall be that: determined from stress verification; or calculated according
to equation (1):
(1) or 17 mm; whichever is the greatest. 6.4 Connection to Packing and Anchor Plates The connections between the bearing plates, packing plates, anchor plates and the main structure shall be capable of transmitting the applied forces and allow the bearings to be replaced if necessary. NOTE
Connections may be provided by bolts, high-strength friction grip bolt connections, shear disks, or pins.
Welding shall be used only if easy access is possible and if the welding and its removal are not detrimental to the bearing components. Internal uplift forces shall be resisted by positive means such as bolts. Friction shall be taken into account only where a positive clamping force such as pre-stress exists or if the guide bearings or restraint bearings are used in combination with a vertical load bearing on a common bearing plate. )(025,022mmbat+×=
