Description

{The Device for Measurement of Displacement of Bridge Bearing Pads}

The present invention relates to an apparatus for measuring displacement of a bridge bearing, and more particularly, to a displacement measurement apparatus capable of measuring an excess displacement of an allowable displacement amount occurring in the past as a numerical value.

In general, bridge bearings, which are supporting devices, are installed at the boundary between the upper structure and the lower structure in order to transmit the force received from the upper structure (bridge girder) to the lower structure (alternation).These supports are functionally viewed to fix the bridge. It is roughly divided into a fixed support installed at a point (fixed point) and a movable support installed at a point (operation point) that facilitates the movement of the upper structure to the lower structure, and the movable support is a one-way support and a left that can only move left and right. There are two-way bearings that move in the, right, vertical and transverse directions.

In addition, the movable bearing is the movement of the bridge due to temperature change, drying shrinkage, and creep (a phenomenon in which the deformation increases with time even after elastic deformation occurs immediately after loading in the concrete with a constant load), etc. It is necessary to have a structure that makes it smooth, and is generally made of an elastomer.

Such movable bearings cause the bridge to move (extension and contraction), such as the extension or contraction of the upper structure of the bridge depending on various external conditions (temperature change or vibration), and accordingly, the movable bearings also move in the longitudinal and transverse directions. Is done.

That is, the lower end of the support is coupled to and fixed to the lower structure of the bridge, and the upper end is coupled to and fixed to the upper structure of the bridge, so the upper end of the support moves as the upper structure of the bridge is expanded. The amount of displacement of the bridge is the subject of inspection during the safety inspection of the bridge, and to measure the amount of displacement, a bridge support measuring device is installed on the support and used.

This displacement amount has a problem that the allowable excess displacement amount that occurred before the time point of measurement by the operator cannot be confirmed. If the displacement that occurred in the past is within the allowable range, there will be no problem, but if the displacement outside the allowable range has occurred, the safety inspection of the bridge must be performed. Therefore, being able to grasp the displacement over the allowable range is important data in that it is possible to more accurately determine the condition of the bridge and thus prepare for future problems.

According to the prior art registration patent No. 10-1618229, when the relative displacement of the guideline 130a exceeds the scale area of the gauge body to the left (when it exceeds the regular displacement of the upper structure of the bridge), the guideline 150 It advances to the left or right while being pushed to display the amount of left or right movement that exceeds the normal displacement of the bridge superstructure, and in case of earthquake displacement, the left moving body 130a and the right moving body 130b are rapidly pushed by the guide 150 While being caught by the stopper protrusions (140a, 140b), it is possible to display a case that exceeds the intermediate displacement between the constant displacement and the seismic displacement, but this cannot be grasped as an exact numerical value, and the left moving body 130a and When the right movable body 130b is broken, the parts need to be replaced, and there is a problem that only the direction of the teaching can be checked.

It can be seen that the bridge support top plate 1 corresponding to the allowable excess range in one direction does not move in the bridge.

In addition, FIG. 9 shows that the bridge bearing upper plate 1 has entered the allowable exceeding range by deviating from the maximum value on the first direction side of the bridge bearing displacement value 24, and the first displacement over displacement person 60a exceeds the first teaching job. It can be seen through what is shown through the instruction window 25. That is, it can be seen that the bridge bearing upper plate 1 has moved 10 mm in the first direction beyond the allowable range.

In addition, FIG. 10 shows that, from the time point of measurement of the displacement amount of the bridge support upper plate 1, the bridge support upper plate 1 has moved by 10 mm within the allowable range toward the first direction, but before that point, the bridge support upper plate 1 It can be seen that there is a history of moving 10 mm in the first direction beyond the allowable range.

The 1st and 2nd throttling excess indication window (22, 23) and the 1st and 2nd teaching staff excess indication window (25, 26) start with the 1st and 2nd throttling excess value, and the 1st and 2nd teaching staff excess value It is preferable that a triangular mark or an arrow is marked on the front of the main body 20 so as to face the end of the start of (61a, 61b) to increase the readability of the numerical value.

In the text, the throttle displacement value 41 of the throttle displacer 40 is the allowable range based on the displacement amount in the first throttle direction 50 mm ~ 50 mm in the second throttle direction. When the displacement exceeds 50 mm, each direction is 80 The allowable excess range is marked so that it can be displayed up to mm.

The first throttling excess value (51a) can measure the displacement amount of +20 mm from the point when the first throttling direction displacement amount exceeds 50 mm, and the second throttling excess value (51b) is the second throttling direction displacement amount exceeding 50 mm From the point of time, the displacement amount of +20 mm can be measured.

The permissible range of the teaching displacement value (24) indicated on the front of the text is based on the displacement amount in the first orthogonal direction of 20 mm to the displacement amount in the second orthogonal direction of 20 mm.

As for the first pedicle excess value (61a), a displacement amount of +10 mm can be measured from the time when the displacement amount in the first pedicle direction exceeds 20 mm, and the second pedagogy excess value (61b) is the displacement amount in the second pedicle direction exceeds 20 mm. From the point of time, the displacement amount of +10mm can be measured.

In the text, both the first direction and the second direction are indicated as absolute values based on the 0 point, but readability can be improved by indicating the direction in which correction and teaching took place with (+) and (-).

This may vary depending on the bridge. The numerical limitation as described above is for illustrative purposes only, and is applicable to various ranges without limiting the scope of the present invention.

The bridge bearing displacement measuring device 100 as described above constitutes the first and second bridge shaft excess displacement elements 50a, 50b and the first and second bridge bearing excess displacement elements 60a, 60b, and the bridge support upper plate (1) It is possible to measure the allowable excess displacement moving outside this allowable range.

In addition, by configuring the throttling displacer fixing part 27 to fix it from the moved position of the first and second throttling excess displacers 50a, 50b, and configuring the teaching displacer fixing part 28, the first and the first The history can be checked even after the point in time when the allowable over-displacement occurs by fixing it from the moved position of the two-rectangular over-displacer (60a, 60b).

In addition, each of the first and second intersecting over-displacers (50a, 50b) and the first and second over-orthogonal displacers (60a, 60b) are made with throttling and intersecting return holes (52, 63) using tweezers. It is easy to return the first and second intersecting over-displacers 50a and 50b and the first and second orthogonal over-displacers 60a and 60b to the initial state.

Lastly, the first and second throttling excess values 51a and 51b and the first and second teaching excess values 61a and 61b are marked with a scale and a number, so that accurate measurement of the allowable excess displacement is possible.
