POT BEARING WITH A BUILT-IN RUBBER PLATE WHICH SEALING RING IS DEPOSITED}

The present invention relates to a port bearing with an integrated rubber plate embedded with a sealing ring. More specifically, the sealing ring is installed in an integrated state with the sealing ring embedded in a rubber plate, thereby limiting the behavior due to the flexibility of the rubber. By almost incompressible behavior, there is no fear that the sealing ring will break off, break or bend from the port bearing during installation or transportation of the port bearing, and the rubber of the rubber sheet will not leak into the gap due to improper assembly of the sealing ring. Since the sealing ring is rubber-coated, it does not come into contact with the intermediate plate, so that even if electrolyte such as rainwater penetrates, there is no danger of the intermediate plate being corroded. Furthermore, it solves the instability of the entire bridge due to failure or failure of one component. Sealing ring that can enhance the stability of the tube It is.

In general, bridge bearings are located at the junctions of bridge decks and bridges or bridges to support loads on vertical loads such as dead loads and live loads, and to slide against horizontal displacements such as temperature expansion and drying shrinkage / creeping of bridge decks. It is a kind of important member in the bridge structure, which has the function of rolling, which can accommodate the rotation of the bridge deck due to the vehicle load, so that the stress caused by the displacement of the superstructure is not transmitted to the alternating and pier excessively. to be.

The bridge support as described above has not been required before the 1970s, the bridge support of the simple beam is not required because there is a flat support or rotation function without the rotation function as described above, but the linear support has a low sliding function has been used a lot, Since the 1980s, roller bearings, which reduced the frictional force of the bearings by applying lubricant to the hinges, have been widely used until the late 1980s, but these roller bearings also had a problem in that maintenance was difficult due to the deterioration of the lubrication effect of long-term use. .

On the other hand, since the late 1980s, pot bearings using sliding fluorine resin plates have been introduced in Korea (Korea), and these pot bearings are shock-absorbed due to the cushioning action of the sealed rubber compared to the roller bearings described above. Its function, rotational function in all directions, ease of maintenance, and replaceable advantages over the service life of the bridge have increased considerably until now.

Hereinafter, with reference to the accompanying drawings will be described in detail the configuration and operation of the present invention.

Figure 4 is an exploded perspective view showing the parts of the present invention, and FIGS. 5A and 5B are partial cutaway perspective views and cross-sectional views respectively showing an embodiment of the integrated rubber plate of the present invention, and FIGS. 6A and 6B are respectively Some cutaway perspective views and cross-sectional views showing another embodiment of the integrated rubber plate of the present invention, Figure 7a, Figure 7b is an assembled cross-sectional view showing how the integrated rubber plate of the present invention is integrated in the port support.

As shown in the present invention, the rubber plate 2 of the prescribed thickness is inserted into the concave cylindrical concave portion 11 of the center upper portion of the lower plate 1, and the rubber plate 2 is inserted and installed as in the conventional base plate. The side surface is formed into a spherical surface to prevent the occurrence of interference during rotation, and the upper and lower surfaces are provided with an intermediate plate (3) formed with a flat surface to transmit a uniform pressure to the rubber plate (2), the intermediate plate ( 3) The sliding member 6 is installed on the upper part, and then the upper plate 5 is put on and bolted together, thereby completing the port support.

The intermediate plate 3 usually uses a lot of metal called SS400, and the sliding member 6 usually uses a lot of fluororesin plates.

Conventional port bearings have a ring shape in order to prevent the rubber of the rubber plate 2 from flowing into the gap between the lower plate side wall 12 and the intermediate plate 3 when the vertical load or the rotation moment acts on the intermediate plate 3. Install the sealing ring (4).

However, the present invention does not assemble to the outer contact surface of the three parts of the rubber plate 2, the lower plate side wall 12 and the intermediate plate 3, as the conventional sealing ring is separate, instead of the rubber plate (2) It is characterized in that the sealing ring is embedded in the upper end and integrated. The sealing ring has a ring shape and is the same as the conventional one, and its material is steel having high strength.

As described above, the sealing ring 4 is embedded in the rubber plate 2 so that the sealing ring functions to limit the behavior due to the flexibility of the rubber. That is, when a vertical load or a rotation moment acts on the intermediate plate 3 by various load conditions, the rubber plate 2 is compressed and the rubber material is subjected to hydrostatic pressure without a volume change. Even when subjected to the uneven load by the rotational moment to the opposite direction by the volume squeezed relative to the axis of rotation of the intermediate plate (3) serves to follow the rotation while receiving hydrostatic pressure. By this tilting, a restoring force is always applied to maintain an equilibrium state.

It is embedded as described above so that the sealing ring does not have to be separated, broken or bent from the port support during installation or transportation, and the rubber of the rubber plate 2 leaks into the gap due to the improper assembly of the sealing ring 4. Above all, the sealing ring is coated with rubber so that the sealing ring does not come into contact with the intermediate plate 3 so that the intermediate plate 3 does not have to be corroded even if electrolyte such as rainwater penetrates. . This is especially useful for flexible bridges, such as suspension bridges, where the sealing function (or sealing function) ages due to frequent translational or climatic conditions. In addition, due to the failure or fault of one component to solve the instability of the entire bridge serves to enhance the stability.

The sealing ring 4 integrated with the rubber plate 2 may have various shapes in cross section, but preferably, as in one embodiment of the present invention, it is rectangular. In another embodiment, it is also possible to have a circular cross section.

In addition, the sealing ring 4 embedded in the rubber plate may be made of one layer, but may also be a form in which several layers are stacked.

As described above, the present invention is installed in a state in which the sealing ring is embedded in the rubber plate and is installed in such a way that the sealing ring restricts the behavior due to the flexibility of the rubber so that the sealing ring can be almost uncompressed, thereby allowing the port to be installed or transported. There is no fear that the sealing ring is separated, broken or bent from the base, and due to the improper assembly of the sealing ring, the rubber of the rubber sheet does not leak into the gap, and the sealing ring is rubber-coated so that it does not come into contact with the intermediate plate. Even if an electrolyte such as rainwater penetrates, the intermediate plate has no effect of being corroded.

Furthermore, it has the effect of reinforcing the stability by solving the instability of the entire bridge due to the failure or fault of one component.
