Description
Palier glissant pour la construction et les travaux
publics
L'invention concerne un palier de glissement pour la construction et les travaux publics, ce palier comportant une couche- de matière synthétique insérée entre une plaque de glissement et une plaque de support.Sliding bearing for construction and works
public
The invention relates to a sliding bearing for construction and public works, this bearing comprising a layer of synthetic material inserted between a sliding plate and a support plate.
Pour la construction d'immeubles et les travaux publics, par exemple pour les ponts, on utilise depuis longtemps des paliers de glissement, mobiles. On connait ainsi des paliers en forme de pots en caoutchouc, des paliers en acier, à point de basculement, des paliers à ligne de basculement, des paliers à calottes et des paliers déformables. De tels paliers de glissement et en particulier dans le cas présent la couche de matière synthétique qui se trouve entre la plaque de glissement et la plaque de support, est de préférence un morceau de polytétrafluoréthylène, qui subit l'effet du fluage à froid et de l'usure. For the construction of buildings and public works, for example for bridges, sliding bearings have been used for a long time. There are thus known bearings in the form of rubber pots, steel bearings, with tilting point, bearings with tilting line, dome bearings and deformable bearings. Such sliding bearings and in particular in the present case the layer of synthetic material which is located between the sliding plate and the support plate, is preferably a piece of polytetrafluoroethylene, which undergoes the effect of cold creep and wear.
I1 est nécessaire dans les constructions cidessus de contrôler les variations de la couche de matière synthétique du palier de glissement pendant la durée de vie de la construction. Jusqu'à présent, cela ne se- fait généralement qu'à l'occasion d'examens en profondeur, prescrits à intervalles réguliers, et en utilisant des appareils de mesure nécessairement appropriés. It is necessary in the above constructions to control the variations of the layer of synthetic material of the sliding bearing during the lifetime of the construction. Until now, this has generally been done only through in-depth examinations, prescribed at regular intervals, and using necessarily appropriate measuring devices.
L'invention a pour but de créer une installation de mesure qui permette de façon simple de mesurer la diminution de l'épaisseur de la couche de matière synthétique d'un palier de glissement sous l'effet du fluage à froid et/ou de l'usure. The object of the invention is to create a measuring installation which makes it possible to measure in a simple manner the reduction in the thickness of the layer of synthetic material of a sliding bearing under the effect of cold creep and / or of the 'wear.
A cet effet, l'invention concerne un palier du type ci-dessus, caractérisé par des moyens pour mesurer la distance entre la plaque de glissement et la plaque de support. To this end, the invention relates to a bearing of the above type, characterized by means for measuring the distance between the sliding plate and the support plate.
Les moyens selon 1-' invention sont constitués par un dispositif de mesure de course qui se compose essentiellement d'un capteur de mesure du commerce, d'un renvoi d'angle adapté au point de mesure correspondant et un dispositif d'affichage de course par exemple un cadran de mesure, un affichage numérique et analogue. The means according to the invention consist of a stroke measurement device which essentially consists of a commercially available measurement sensor, an angle gear adapted to the corresponding measurement point and a stroke display device for example a measurement dial, a digital display and the like.
Les moyens p-our mesurer l'écartement sont selon l'invention, prévus au moins en trois endroits à la périphérie du palier de'glissement. Lorsqu'il s'agit d'un organe de palier de glissement de forme ronde, on prévoit les moyens de mesure de distance entre trois endroits à la périphérie. Lorsque le palier de glissement présente une forme. rectangulaire, on prévoit des points de mesure de chaque côté du rectangle. The means for measuring the spacing are according to the invention, provided at least in three places on the periphery of the sliding bearing. In the case of a sliding bearing member of round shape, means are provided for measuring the distance between three places on the periphery. When the sliding bearing has a shape. rectangular, measurement points are provided on each side of the rectangle.
Le dispositif de mesure selon l'invention peut déja être monté sur le palier de glissement avant la mise en place du palier. Il est également possible d'équiper à postériori un palier de glissement déjà mis en place dans une construction, avec une telle installation de mesure. The measuring device according to the invention can already be mounted on the sliding bearing before the establishment of the bearing. It is also possible to retrofit a sliding bearing already installed in a construction, with such a measuring installation.
L'invention permet à tout instant et sans préparation particulière, d'effectuer un contrôle et une mesure surs de l'état d'un palier de- glissement. The invention makes it possible at any time and without any particular preparation, to carry out a safe control and measurement of the state of a sliding bearing.
L'invention sera décrite ci-après à l'aide des dessins annexés, dans lesquels
- la figure 1 est une coupe transversale d'un palier de glissement.The invention will be described below using the accompanying drawings, in which
- Figure 1 is a cross section of a sliding bearing.
- la figure 2 montre le détail II de la figure 1 à échelle agrandie. - Figure 2 shows the detail II of Figure 1 on an enlarged scale.
Dans l'exemple de réalisation selon la figure 1, le corps du palier de glissement se compose de la plaque de glissement 1, avec une tôlé de glissement 2 placée en-dessous, de la plaque de support 5 et de la couche de matière synthétique 3 insérée dans la. plaque de support ; cette couche se présente sous la forme d'un morceau de polytétrafluoréthylène PTFE. In the example of embodiment according to FIG. 1, the body of the sliding bearing consists of the sliding plate 1, with a sliding sheet 2 placed below, the support plate 5 and the layer of synthetic material. 3 inserted in the. support plate; this layer is in the form of a piece of polytetrafluoroethylene PTFE.
Du reste, on peut également envisager le cas de paliers de glissement inversés, avec en partie haute. Moreover, we can also consider the case of reverse sliding bearings, with the upper part.
la plaque de support et 1 couche de matière synthétique insérée, et en-dessous la plaque de glissement avec la tôle de glissement.the support plate and 1 layer of synthetic material inserted, and below the sliding plate with the sliding plate.
-A la place de la tôle de glissement prévue sur la plaque de glissement, on peut également avoir une plaque de glissement munie d'une couche de chrome ou analogue. -In place of the sliding plate provided on the sliding plate, one can also have a sliding plate provided with a layer of chromium or the like.
Selon la figure 2, une patte 9 est soudée latéralement sur la plaque de support 5 ; un capteur de mesure 6 est placé dans cette patte. Une transmission d'angle 8 relie le capteur de mesure 8 avec le cadran d'affichage 7. According to Figure 2, a tab 9 is welded laterally on the support plate 5; a measurement sensor 6 is placed in this tab. An angle transmission 8 connects the measurement sensor 8 with the display dial 7.
-La mesure concerne l'intervalle 4 entre la tôle de glissement 2 et la plaque de support 5. Cet intervalle 4 diminue pendant la durée de vie de la construction du fait du fluage à froid et de l'usure d la pièce en polytétrafluoréthylène PTFE 3. -The measurement concerns the interval 4 between the sliding plate 2 and the support plate 5. This interval 4 decreases during the lifetime of the construction due to cold creep and wear of the polytetrafluoroethylene PTFE part. 3.
L'invention peut également s'appliquer de façon évidente à d'autres types de paliers de glissement qe les types décrits et représentés ci-dessus, et dans lesquels il faut procéder à un contrôle et à une mesure permanents ou périodiques de la diminution de l'épaisseur de la couche de matière synthétique, insérée dans le palier. The invention can also obviously be applied to other types of sliding bearings qe the types described and represented above, and in which a permanent or periodic control and measurement of the reduction in the thickness of the layer of synthetic material inserted in the bearing.
