Description

Simultaneous measurement apparatus for movement and inclination of bridge bearings and bridge bearings having the same

The present invention relates to a device for simultaneously measuring movement and inclination of a bridge bearing, which is mounted on a bridge bearing, and which can easily check the movement and inclination even if the bridge bearing is moved to the left or right or tilted, and a bridge bearing having the same.

In general, a bridge bearing, which is a support device, is installed at the boundary between the upper structure and the lower structure in order to transmit the force received from the upper structure to the lower structure in the bridge.

Such bridge bearings need to have a structure that facilitates the movement of the bridge due to temperature changes, drying shrinkage, creep, etc. These bridge bearings move longitudinally and transversely according to the extension or decrease of the upper structure of the bridge according to various external conditions (temperature change or vibration), or the weight applied to the bridge is applied to one place and inclines. That is, since the lower plate of the bridge bearing is fixed to the lower structure of the bridge and the upper plate is fixed to the upper structure of the bridge, as the upper structure of the bridge expands and contracts, the upper plate of the bridge bearing also moves.

The amount of expansion and contraction of the bridge is subject to inspection during safety inspection of the bridge, and a measuring meter is installed on the support to measure the amount of expansion and contraction. In this regard, FIG. 1 shows a state in which the measuring system 10 is installed on the bridge bearing 20 . Here, the measuring system 10 is composed of a measuring unit 11 on which a scale is printed and an indicator 12 in which an indicator 14 indicating a scale printed on the measuring unit 11 is formed on the upper end of the body 13, , a measuring hand 19 indicating the scale printed on the measuring unit 11 is provided.

When the measuring system 10 is installed on the bridge bearing as described above, the upper plate of the bridge is expanded and contracted due to climatic conditions, traffic volume, etc., and when the upper plate of the bridge bearing 20 is moved to the left or right, the measurement unit 11 moves together. Accordingly, the state in which the pointer 14 of the indicator 12 indicates the central portion of the scale printed on the measurement unit 11 is changed, and thus indicates the left or right side from the center of the scale, and in this process, the measurement unit ( 11) also changes its position by the pointer 14.

Afterwards, when the upper side of the bridge bearing 20 is returned to its original state, the pointer 14 again points to the center of the scale, but the measuring unit 11 does not return to its original position and is at a point moved to the outside, At this position, the reading of the scale indicated by the measuring needle 19 of the measuring unit 11 becomes the maximum value at which the bridge is stretched and contracted.

However, according to this prior art, although the left and right displacement can be confirmed, the tilting movement of the bridge bearing cannot be confirmed, and there is a problem that separate equipment is required to measure the tilted displacement.

Since the present invention can have various changes and can have various forms, specific embodiments are illustrated in the drawings and described in detail in the text. However, this is not intended to limit the present invention to the specific disclosed form, it should be understood to include all modifications, equivalents and substitutes included in the spirit and scope of the present invention. In describing each figure, like reference numerals have been used for like elements. In the accompanying drawings, the dimensions of the structures are enlarged than the actual for clarity of the present invention, or shown reduced than the actual in order to understand the schematic configuration.

The device for simultaneously measuring the movement and inclination of the bridge bearing according to the present invention is installed on the bridge bearing 20 composed of the upper plate 21 , the lower plate 22 and the pedestal 23 as shown.

The upper plate 21 serves to connect the bridge top plate and the pedestal 23 , and the lower plate 22 serves to connect the pier and the pedestal 23 .

The pedestal 23 is formed by stacking elastic rubber and reinforcing steel plates with each other, and serves to correct the bridge top plate when it is stretched and deformed. The pedestal 23 has a shape in which reinforcing steel plates are horizontally inserted at regular intervals between tetrahedral elastic rubbers. In this case, the support 23 is preferably displayed in different colors so that the fixed bridge support, the one-way bridge support, and the two-way bridge support can be identified according to the type used.

On the other hand, the apparatus for measuring the movement and inclination of the bridge bearing at the same time includes a rotation shaft 110 , a movement scale unit 120 , a movement instruction unit 130 , a tilt scale unit 140 , and a slope instruction unit 150 .

The rotating shaft 110 is located in the center of the upper plate 21 and is fixed by being embedded in the upper plate 21 and is composed of a pin or a bolt having a head.

The moving scale unit 120 includes a plurality of moving scales formed on the lower plate 22 . These movement scales are formed by being spaced apart from each other by a predetermined interval in the left and right direction based on the movement guide 131 of the movement indicating unit 130 in a vertical state on the lower plate 22 . Here, it is preferable that the moving scales are spaced apart by an interval of mm, and different colors are displayed at even-numbered or odd-numbered positions for easy identification.

And, when the movement instructing unit 130 is positioned vertically, the movement instruction 131 of the movement instructing unit 130 is located at the center of the movement scales, and when the movement instructing unit 130 moves to the left, the movement instruction unit 130 ), the movement guide 131 is positioned from the central movement scale to the left movement scale, so that the length of the transition can be measured.

The movement indicator 130 has an upper end rotatably installed on the upper plate 21 , and a movement guide 131 with a sharply protruding lower end indicates the movement scale unit 120 . Here, in a state in which the movement indicator 130 is vertical, the movement guide 131 indicates a movement scale located at the center among the movement scales of the movement scale unit 120 . At this time, when the upper plate 21 is moved, the movement instructing unit 130 also moves and instructs another movement scale spaced apart from the central movement scale. Accordingly, the manager can visually check the movement scale indicated by the movement guide 131 of the movement instruction unit 130 to measure that the upper plate 21 is moved by the spaced interval between the movement scales.

In addition, the movement indicating unit 130 is mounted in a mounting hole formed on the upper portion of the bearing 132 through which the rotating shaft 110 passes, and the rotating shaft 110 while being supported by the rear surface and the upper plate 21 of the bearing 132 . It includes a rear washer 133 that passes through, and a front washer 134 through which the rotating shaft 110 passes while being supported on the front surface and the inclination scale part 140 of the bearing 132 .

The bearing 132 is composed of an inner ring on which one side of the balls is supported and an outer ring on which the other side of the balls is supported, and a rear washer 133 and a front washer 134 are supported on the front and rear surfaces of the inner ring, and the outer ring The outer circumferential surface of the is fixed by being forcibly inserted into the mounting hole.

As the rear washer 133 is supported on the upper plate 21, the rotation shaft 110 passes through and the front washer 134 passes through the rotation shaft 110 while the front washer 134 is supported on the inclination scale unit 140, so the movement instruction unit 130 is It does not interfere with the upper plate 21 or the inclination scale unit 140 .

Therefore, when the upper plate 21 is inclined, the movement indicating unit 130 is rotated along with the outer ring around the inner ring, so that it can always be maintained in a vertical state.

The inclination scale unit 140 has an upper portion fixedly installed on the upper plate 21 by the rotation shaft 110 , and a plurality of inclination scales are formed at the lower portion to be spaced apart from one another to the left and right. These, the inclination scale unit 140 is displayed in the center from 0 ° to the left, the inclination angles of 2 °, 4 °, 6 °, 8 °, and also from 0 ° to the right 2 °, 4 °, 6 °, 8 The angle of inclination in ° is displayed. At this time, inclination angles of 1°, 3°, 5°, and 7° may be displayed to enable precise measurement between 2°, 4°, 6°, and 8°.

In addition, the inclination scale unit 140 has a through hole formed therein so that the rotation shaft 110 passes therethrough. Accordingly, as the rotation shaft 110 is fixed to the upper plate 21 , the head of the pin or bolt, which is the rotation shaft 110 , is supported on the front surface of the inclination scale unit 140 , and the front washer on the rear surface of the inclination scale unit 140 . Since the 134 is supported, when the upper plate 21 is rotated, the inclination scale 140 is rotated together with the upper plate 21 . At this time, when the inclination scale unit 140 is rotated, since the inclination guide 151 of the inclination indicator 150 indicates the inclination scale, the administrator can check it.

The inclination indicator 150 is installed with a fixed lower portion on the movement indicator 130 , and the inclination guide 151 with a sharply protruding upper end is formed to indicate the inclination scale of the inclination scale unit 140 .

In addition, the inclination indicator 150 includes an upper plate on which the inclination guide 151 is formed at the upper end while being vertical, a middle plate with one end connected to the lower end of the upper plate and a horizontal middle plate, and a movement instruction unit 130 while continuing vertically from the other end of the middle plate to the bottom. ) is made of a lower plate that is fixedly installed on the At this time, as the lower plate is fixed to the movement indicating unit 130 with a bolt, the inclination guide 151 is spaced apart from the movement indicating unit 130 while facing upward. That is, the inclination guide 151 is also spaced apart from the inclination scale unit 140 which is installed close to the movement indicating unit 130 and does not interfere.

Accordingly, when the upper plate 21 is tilted to the right, the tilt indicating unit 150 together with the movement indicating unit 130 forms a vertical state without being tilted. At this time, since the inclination scale unit 140 is rotated to the right and inclined, the inclination guide 151 of the inclination indicator 150 in a vertical state indicates the right inclination scale displayed on the inclination scale unit 140 . For example, when the operator checks 4° of the inclination scale indicated by the inclination guide 151, it can be measured that the upper plate 21 is rotated to the right by an angle of 4° to be tilted.

Let's look at the operating state of the device for simultaneously measuring the movement and inclination of the bridge bearing according to the present invention.

First, a bridge support consisting of an upper plate 21 , a lower plate 22 , and a pedestal 23 is installed between the pier and the bridge top plate.

Then, the inclination instructing unit 150 is vertically fixed to the movement instructing unit 130 of the movement and inclination measuring device with bolts. At this time, the inclination indicator 150 is vertical so that the inclination indicator 151 faces the upper end of the movement indicator 130 .

Then, the rotation shaft 110 of the movement and inclination measuring device passes through the inclination scale unit 140, the front washer 134, the bearing 132, and the rear washer 133 in order to the upper plate 21. screwed in and fixed.

Here, in a state in which the rotation shaft 110 is not completely fixed to the upper plate 21 and the movement instruction unit 130 of the movement and inclination measuring device is vertically positioned, the movement guide 131 is the movement scale portion 120 of the Indicate the center among the movement scales.

In addition, the inclination scale unit 140 is also vertically adjusted to be vertical in parallel with the movement indicating unit 130 . At this time, the inclination scale unit 140 is positioned between the movement indicating unit 130 and the inclination indicating unit 150 .

In this way, in a state in which the installation of the movement and inclination measuring device is completed, the movement guide 131 of the movement instructing unit 130 of the movement and inclination measurement device indicates the center (0 mm) among the movement scales of the movement scale unit 120 . This will confirm that the bridge bearing is installed correctly. Accordingly, it is possible to simply check that the bridge bearing is correctly installed using the movement and inclination measuring device.

On the other hand, when checking the displaced state of the bridge over time, check the movement scale indicated by the movement guide 131 of the movement instruction unit 130 to determine the direction and movement of the upper plate 21 to the left or right The distance can be checked, and the upward or downward inclination direction and the inclination value of the upper plate 21 are measured by checking the inclination scale of the inclination scale unit 140 indicated by the inclination guide 151 of the inclination indicator 150 . can do,

In this way, by checking the movement indicating unit 130 and the inclination indicating unit 150, the movement displacement and the inclination displacement of the support device are simply measured, and when the reference displacement is exceeded, a corresponding action can be taken.
