Description

The present invention relates to a bearing device that allows the upper building to slide while supporting the upper building, for example, by interposing between the lower building and the upper building, and a method of assembling the bearing device.

Conventionally, for example, there is a bearing device that movably supports a bridge, a seismic isolated building, or a building in which vibration or relative displacement occurs, such as a connecting portion connecting fixed buildings. Such a bearing device is arranged between a supported structure such as a main girder and a supported structure such as a pier, and is fixed to a support structure and a upper sill fixed to the supported structure. By sliding the boundary surface with the lower pier, that is, the sliding surfaces, it is possible to support the boundary surface so as to be displaceable in the in-plane direction.

For example, Patent Document 1 discloses a one-way bearing device having a one-way sliding direction as one of the bearing devices.
Specifically, the bearing device of Patent Document 1 faces the sliding surface in a direction substantially parallel to the sliding surface at a predetermined interval, and is provided with a pair of guide walls erected downward on the upper sill. The lower sill slides between the guide walls, enabling sliding in the desired sliding direction (one direction).

By the way, in recent years, in a support device that can slide in one direction as in Patent Document 1, in order to suppress rattling in the orthogonal direction that is substantially parallel to the sliding surface and substantially orthogonal to the sliding direction, the upper part in the orthogonal direction. There is a need to make the gap between the sill and the lower sill as small as possible.

However, for example, as shown in FIG. 12 showing a front view of the one-way support device 100 of the prior art, when the gap G between the upper shoe 110 and the lower shoe 120 in the orthogonal direction Y is not zero, the upper shoe 110 and the lower shoe 120 Can be easily assembled in the vertical direction, but when the gap G is zero, there is a problem that it becomes difficult to assemble the upper shoe 110 and the lower shoe 120.

According to this configuration, the bearing device can reliably bring the regulated slip member into contact with the second shoe regardless of the accuracy of the length of the regulated slip member in the orthogonal direction.

Further, since the bearing device can abut the regulated slip member against the second shoe with a stable load, it is possible to suppress the fluctuation of the sliding resistance between the regulated slip member and the second shoe. Therefore, the bearing device can slide the sliding surfaces more smoothly.

It is characterized in that the mounting step of mounting the set of regulated slip members to the base portion is performed in this order.
According to the present invention, the method of assembling the bearing device is to make the gap between the first shoe and the second shoe zero in the orthogonal direction without impairing the assembling property between the first shoe and the second shoe. can.

Next, in the one-way bearing device 1 having the above-described configuration, an assembling method for assembling the upper shoe 10 to the lower shoe 20 will be described with reference to FIGS. 6 and 7.
Note that FIGS. 6 and 7 show schematic views illustrating a method of assembling the one-way bearing device 1. Specifically, FIG. 6A shows an explanatory diagram illustrating a first contact step of bringing the upper shoe sliding surface 12a into contact with the lower shoe sliding surface 22a, and FIG. 6B shows a side bearing 23. An explanatory diagram illustrating a second contacting step of bringing the shoe into contact with the upper sill 10 is shown.

Further, FIG. 7A shows an explanatory diagram illustrating a cutting process for cutting the extra length portion 23b of the side bearing 23, and FIG. 7B illustrates a mounting process for mounting the side bearing 23 on the guide wall 27. An explanatory diagram is shown.

First, as a method of assembling the one-way bearing device 1, as shown in FIG. 6A, the upper shoe 10 is mounted from above on the lower shoe 20 to which the side bearing 23 and the holding member 24 are not mounted. Place. At this time, in the method of assembling the one-way bearing device 1, the upper shoe sliding surface 12a of the upper shoe 10 is placed on the lower shoe sliding surface 22a of the lower shoe 20, and the lower shoe sliding surface 22a is placed. And the sliding surface 12a of the upper bearing are brought into contact with each other.

Next, as shown in FIGS. 6 (a) and 6 (b), the method of assembling the one-way bearing device 1 is as follows. The side bearing 23 is inserted into the through hole 27d of the guide wall 27 toward the lower portion 14 of the sole plate. At this time, the method of assembling the one-way bearing device 1 is to insert the side bearing 23 to a position where the end surface 23a abuts on the lower portion 14 of the sole plate.

After that, as shown in FIGS. 6B and 7A, the method of assembling the one-way bearing device 1 is to cut the extra length portion 23b exposed from the outer surface 27a of the guide wall 27 to cut the side bearing 23. Is shaped so that the outer surface 27a of the guide wall 27 and the end surface of the side bearing 23 are substantially flush with each other.

Then, in the method of assembling the one-way bearing device 1, as shown in FIG. 7B, the pressing member 24 is brought into contact with the outer surface 27a of the guide wall 27, and the bolt 25 is screwed into the screw hole 27c. As a result, the holding member 24 is fastened and fixed to the guide wall 27.

Thereby, in the assembling method of the one-way bearing device 1, the movement of the side bearing 23 in the orthogonal direction Y is restricted by the sole plate lower portion 14 of the upper shoe 10 and the pressing member 24.
As described above, in the method of assembling the one-way bearing device 1, the gap between the side bearing 23 and the upper shoe 10 in the orthogonal direction Y is set to zero, and the upper shoe 10 is assembled to the lower shoe 20.

As described above, the one-way bearing device 1 is composed of the lower shoe 20 and the upper shoe 10 arranged at the opposite portions of the lower building 3 and the upper building 2, respectively, with the lower shoe 20 and the upper frame 10. This is a bearing device in which the sliding surfaces 12a and 22a at the facing portions slide in the sliding direction X.

The lower sill 20 of the one-way bearing device 1 is in a state where the base spot 21 provided with the lower sill sliding surface 22a and the sliding surfaces 12a and 22a are in contact with each other, and the lower sill 20 is orthogonal to the upper sill 10 in the direction Y. It is provided with a set of side bearings 23 that are abutted from both sides of the base and are mounted on the base spot 21.

According to this, the one-way bearing device 1 can make the gap between the lower shoe 20 and the upper shoe 10 in the orthogonal direction Y zero without impairing the assembling property between the lower shoe 20 and the upper shoe 10. .. Further, since the lower sill 20 and the upper sill 10 are slidable by the side bearing 23, the one-way bearing device 1 slides even if the gap between the lower sill 20 and the upper sill 10 in the orthogonal direction Y is zero. The moving surfaces 12a and 22a can be slid smoothly with each other.

Further, the base spot 21 of the lower shoe 20 is provided with a guide wall 27 having a through hole 27d into which the side bearing 23 is inserted, while facing each other in the orthogonal direction Y with the upper shoe 10 interposed therebetween. The lower shoe 20 covers the through hole 27d into which the side bearing 23 is inserted, and is provided with a pressing member 24 fixed to the guide wall 27.

As a result, the one-way bearing device 1 can restrict the movement of the side bearing 23 in the orthogonal direction Y, so that the side bearing 23 can be stably brought into contact with the upper shoe 10.
Further, in the one-way bearing device 1, for example, when the side bearing 23 is worn, the side bearing 23 can be replaced only by attaching and detaching the pressing member 24. Therefore, the one-way bearing device 1 can improve maintainability.

Further, the method of assembling the one-way bearing device 1 is composed of a lower shoe 20 and an upper shoe 10 arranged at opposite portions in the lower building 3 and the upper building 2, respectively, and the lower frame 20 and the upper frame 10 are assembled. This is an assembly method in a bearing device in which the sliding surfaces 12a and 22a at the facing portions of the above slide in the sliding direction X.

First, the method of assembling the one-way bearing device 1 is a first contact step in which the lower shoe sliding surface 22a provided on the base spot 21 of the lower shoe 20 and the upper shoe sliding surface 12a of the upper shoe 10 are brought into contact with each other. I do.
Next, in the method of assembling the one-way bearing device 1, a second contact step is performed in which a set of side bearings 23 are brought into contact with the upper shoe 10 from both sides in the orthogonal direction Y.

After that, the method of assembling the one-way bearing device 1 is to perform a mounting step of mounting a set of side bearings 23 to the base spot 21.
Thereby, the method of assembling the one-way bearing device 1 is to make the gap between the lower shoe 20 and the upper shoe 10 in the orthogonal direction Y zero without impairing the assembling property between the lower shoe 20 and the upper shoe 10. Can be done.

Further, in the second contact step, the side bearing 23 is inserted into the through hole 27d provided in the guide wall 27 of the base spot 21 facing in the orthogonal direction Y across the upper shoe 10 to bring it into contact with the upper shoe 10. It is a process.
Further, the mounting step is a step of covering the through hole 27d into which the side bearing 23 is inserted with the pressing member 24 and fixing the pressing member 24 to the guide wall 27.
The method of assembling the one-way bearing device 1 is the extra length of the side bearing 23 protruding from the through hole 27d toward the side opposite to the upper shoe 10 after the second contact step and before the mounting step. The cutting step of cutting the portion 23b is performed.

Thereby, in the method of assembling the one-way bearing device 1, the side bearing 23 can be surely brought into contact with the upper shoe 10. Therefore, the method of assembling the one-way bearing device 1 can surely make the gap between the lower shoe 20 and the upper shoe 10 in the orthogonal direction Y zero.

The one-way bearing device 1 of the second embodiment is different from the first embodiment in that the side bearing is provided with a configuration for applying an urging force in the orthogonal direction Y. Such a one-way bearing device 1 of the second embodiment will be described with reference to FIG.

Note that FIG. 8 shows a cross-sectional view taken along the line AA of the one-way bearing device 1 in the second embodiment.
Further, the same configuration as that of the first embodiment is designated by the same reference numerals, and detailed description thereof will be omitted.

As shown in FIG. 8, the lower sill 20 of the one-way bearing device 1 in the second embodiment has a presser member 24 and a bolt in addition to the base spot 21, the slide bearing 22, the side bearing 28, the presser member 24, and the bolt 25. An elastic member 29 interposed between the head of the 25 and the head of the 25 is provided.

The side bearing 28 is a columnar body made of PTFE having self-lubricating properties and having an inner end face in the orthogonal direction Y having a low coefficient of friction. As shown in FIG. 8, the side bearing 28 is mounted on the guide wall 27 of the base spot 21 so that the gap between the upper sill 10 and the lower portion 14 of the sole plate 10 in the orthogonal direction Y becomes zero.

Specifically, as shown in FIG. 8, the side bearing 28 has an orthogonal direction Y slightly longer than the distance W in the orthogonal direction Y from the outer surface 27a of the guide wall 27 to the lower portion 14 of the sole plate of the upper shoe 10. Preformed to length. Therefore, in the state where the side bearing 28 is in contact with the lower portion 14 of the sole plate of the upper shoe 10, the outer end portion in the orthogonal direction Y is slightly outside the outer surface 27a of the guide wall 27 in the orthogonal direction Y. It is exposed to the side.

Further, as shown in FIG. 8, the pressing member 24 is in contact with the end surface of the side bearing 28 exposed to the outer side in the orthogonal direction Y, not the outer surface 27a of the guide wall 27, unlike the first embodiment. ..

Further, the elastic member 29 is, for example, synthetic rubber having elasticity, and is formed in a substantially cylindrical shape or a substantially annular shape through which the shaft portion of the bolt 25 can be inserted. As shown in FIG. 8, the elastic member 29 elastically deforms in the orthogonal direction Y with the tightening of the bolt 25, and in a state where the bolt 25 is tightened with a specified torque, the pressing member exerts an urging force in the orthogonal direction Y. It is attached to the side bearing 28 via 24.

Such a one-way bearing device 1 of the second embodiment can exhibit the same effect as that of the first embodiment described above.
Further, the lower sill 20 of the one-way bearing device 1 in the second embodiment includes an elastic member 29 that applies an urging force in the orthogonal direction Y toward the upper sill 10 to the side bearing 28.

As a result, the one-way bearing device 1 can reliably bring the side bearing 28 into contact with the upper shoe 10 regardless of the accuracy of the length of the side bearing 28 in the orthogonal direction Y.
Further, since the one-way bearing device 1 can abut the side bearing 28 against the upper shoe 10 with a stable load, it is possible to suppress fluctuations in the sliding resistance between the side bearing 28 and the upper shoe 10. Therefore, the one-way bearing device 1 can slide the sliding surfaces 12a and 22a more smoothly.

The present invention is not limited to the configuration of the above-described embodiment, and many embodiments can be obtained.

For example, in the above description, the one-way bearing device 1 is used when the corridor connecting the buildings is supported from the building, but when the main girder is supported by the pier, the truss roof is supported by the pillar, and the like. It may be used as a one-way bearing device. Further, it may be used as a one-way bearing device in an expansion structure connecting buildings to each other.

Further, a one-way bearing device may be configured in which the configuration of the upper shoe 10 in the above description is provided in the lower shoe and the configuration of the lower shoe 20 is provided in the upper shoe.
Further, in the above description, the sole plate of the upper shoe 10 is integrally formed with the sole plate upper portion 13 and the sole plate lower portion 14, but the present invention is not limited to this, and the sole plate upper portion 13 and the sole plate lower portion 14 are formed. May be composed of separate bodies.

Further, the bottom portion 14 of the sole plate has a shape in which the length in the vertical direction is longer than the length in the vertical direction in the upper portion 13 of the sole plate, but the shape is not limited to this, and the length in the vertical direction is shorter than the length in the vertical direction in the upper portion 13 of the sole plate. It may be in shape.

Further, although the upper sill 10 provided with the stainless steel slide plate 12, the upper sill 10 provided with the stainless steel slide plate may be used instead of the stainless steel slide plate, for example, the upper sill provided with the slide bearing made of PTFE.
Further, the slide bearing 22 of the lower sill 20 is made of a PTFE plate material, but not only made of PTFE, but also other resin materials (for example, polyamide) as long as it has appropriate deformability, strength, and slip performance. It may be composed of a metal such as graphite, ceramics, or copper.
Further, although the slide bearing 22 has a substantially circular shape in a plan view, the slide bearing 22 is not limited to this, and a slide bearing having a substantially rectangular shape in a plan view may be used.

Further, in the above description of the second embodiment, the elastic member 29 is used as a means for applying the urging force to the side bearing 28, but the present invention is not limited to this, and if the urging force can be applied to the side bearing 28, the spring. It may be a washer, a coil spring, or the like.
Further, the elastic member 29 as a urging means is provided between the pressing member 24 and the head of the bolt 25, but the present invention is not limited to this, and the urging means is interposed between the side bearing and the pressing member. May be good.

For example, a side bearing having a length in the orthogonal direction Y shorter than the distance W in the orthogonal direction Y from the outer surface 27a of the guide wall 27 to the lower portion 14 of the sole plate of the upper shoe 10 and a coil spring as an urging means. By inserting it into the through hole 27d of the lower sill 20, an urging means may be interposed between the side bearing and the pressing member.

Further, in the above description, the side bearings 23 and 28 are not fixed to the presser member 24, but the present invention is not limited to this, and the side bearings may be bonded and fixed to the presser member in advance.
At this time, the side bearings are formed to have substantially the same length in the orthogonal direction Y at the interval W in the orthogonal direction Y from the outer surface 27a of the guide wall 27 to the lower portion 14 of the sole plate of the upper shoe 10.
In the one-way bearing device 1 having such a configuration, the end surface 23a of the side bearing 23 can be brought into contact with the lower portion 14 of the sole plate of the upper shoe 10 as the pressing member 24 is attached to the guide wall 27.

Further, in the above description, the base spot 21 of the lower shoe 20 is integrally formed with the base spot main body 26 and the pair of guide walls 27, but the base spot main body and the pair of guide walls are separate bodies. It may be used as a sole plate. In this case, the side bearing may be configured to be adhesively fixed to the guide wall in advance.

Further, as shown in FIG. 9, which shows a cross-sectional view taken along the line AA of the one-way bearing device 1 in another embodiment, in addition to restricting sliding in the orthogonal direction Y, it also restricts relative movement in the vertical direction. It may be a one-way bearing device 1 provided with a regulating means.

Specifically, as shown in FIG. 9, the regulating means for restricting the relative movement in the vertical direction is provided on the flange portion 15 provided on the sole plate 11 of the upper shoe 10 and the pressing member 30 on the lower shoe 20. It is composed of a stopper portion 32.

As shown in FIG. 9, in the one-way bearing device 1, the vertical distance H1 between the flange portion 15 of the upper shoe 10 and the stopper portion 32 of the lower shoe 20 is lower than the sole plate upper portion 13 of the upper shoe 10. It is configured to be narrower than the vertical distance H2 from the stopper portion 32 of the shoe 20.

More specifically, as shown in FIG. 9, the sole plate 11 of the upper flange 10 is located on the outer side in the orthogonal direction Y so that the side bearing 23 abuts on the portion of the lower portion 14 of the sole plate facing the side bearing 23. The flange portion 15 is formed by projecting toward the surface.

On the other hand, as shown in FIG. 9, the pressing member 30 of the lower sill 20 has a main body portion 31 that abuts on the outer surface 27a of the guide wall 27 of the base spot 21 and an inner side in the orthogonal direction Y from the upper end of the main body portion 31. It is integrally formed with the stopper portion 32 extending toward. As shown in FIG. 9, the stopper portion 32 of the pressing member 30 is formed to have a length in the orthogonal direction Y facing upward with respect to the flange portion 15 of the upper shoe 10.

As described above, the upper shoe 10 of the one-way bearing device 1 is provided with a flange portion 15 protruding in the orthogonal direction Y. The pressing member 30 is provided with a stopper portion 32 that restricts the movement of the upper shoe 10 in the vertical direction in which the sliding surfaces are separated from each other by the flange portion 15.
As a result, the one-way bearing device 1 can regulate the relative movement of the lower shoe 20 and the upper shoe 10 in the vertical direction while suppressing an increase in the number of parts.

Further, a side bearing that abuts on the side portion of the sole plate lower portion 14 of the upper shoe 10 may be provided at the tip of the stopper portion 32 described above in the orthogonal direction Y. In this case, the side bearing 23 inserted into the guide wall 27 of the lower shoe 20 may or may not be provided.

Further, the bearing device is composed of the upper shoe 10 and the lower shoe 20, but the present invention is not limited to this, and as in the bearing device 50 shown in FIGS. 10 and 11, between the lower shoe 60 and the upper shoe 70. The structure may be such that the middle sill 80 intervenes. In this bearing device 50, the sliding surfaces of the lower shoe 60 and the middle shoe 80 slide in the sliding direction X, and the sliding surfaces of the upper shoe 70 and the middle shoe 80 slide in the sliding direction X in a plan view. It is configured to slide in a substantially orthogonal orthogonal direction Y.

In other words, when the support device 50 slides in the sliding direction X, the lower shoe 60 becomes the first shoe, the upper shoe 70 and the middle shoe 80 become the second shoe, and the support device 50 slides in the orthogonal direction Y. When moving, the lower shoe 60 and the middle shoe 80 become the first shoe, and the upper shoe 70 becomes the second shoe, and are configured to be slidable.

More specifically, as shown in FIGS. 10 and 11, the lower sill 60 has a lower sill body 61 having a substantially rectangular plan view long in the sliding direction X and a sliding direction X arranged on the upper surface of the lower sill body 61. It is equipped with a slide plate 62 having a long plan view and a substantially rectangular shape. Further, the lower shoe 60 includes a side bearing 63 arranged on the guide wall 61a of the lower shoe main body 61 facing in the orthogonal direction Y, and a pressing member 64 fixed to the guide wall 61a. As shown in FIGS. 10 and 11, the pressing member 64 has a stopper portion 64a that restricts movement in the vertical direction.

As shown in FIGS. 10 and 11, the upper shoe 70 has substantially the same shape as the lower shoe 60 turned upside down, and is arranged so that its longitudinal direction substantially coincides with the orthogonal direction Y. As shown in FIGS. 10 and 11, the upper sill 70 has a rectangular upper sill main body 71 having a long plan view in the orthogonal direction Y and a long plan view in the orthogonal direction Y arranged on the lower surface of the upper sill main body 71. It is provided with a rectangular slide plate 72.

Further, the upper shoe 70 includes a side bearing 73 arranged on the guide wall 71a of the upper shoe main body 71 facing in the sliding direction X, and a pressing member 74 fixed to the guide wall 71a. As shown in FIGS. 10 and 11, the pressing member 74 has a stopper portion 74a that restricts movement in the vertical direction.

The middle shoe 80 is configured to be integrally slidable with the lower shoe 60 as the first shoe and to be integrally slidable with the upper shoe 70 as the second shoe. Specifically, as shown in FIGS. 10 and 11, the center shoe 80 includes a substantially columnar center shoe body 81 extending in the vertical direction, a lower slide bearing 82 provided on the lower surface of the center shoe body 81, and a center. It is provided with an upper slide bearing 83 provided on the upper surface of the shoe body 81.

Further, the middle sill body 81 of the middle sill 80 protrudes in the orthogonal direction Y and abuts on the side bearing 63 of the lower sill 60, and the middle sill main body 81 protrudes in the sliding direction X to the side bearing 73 of the upper sill 70. It is formed in a shape having a second flange portion 81b that comes into contact with the second flange portion 81b.

Even with such a configuration, the support device 50 does not impair the assembling property of the lower shoe 60, the upper shoe 70, and the middle shoe 80, and the gap between the lower shoe 60 and the middle shoe 80 in the orthogonal direction Y. And the gap between the upper shoe 70 and the middle shoe 80 in the sliding direction X can be made zero.
