Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a gauge for moving a bridge,

The present invention relates to a movement amount gauge for a bridge support, and more particularly, to a movement amount gauge for a bridge support, in which not only an ordinary displacement but also an intermediate displacement exceeding it, a seismic displacement and other abnormal displacements can be tracked step by step, And more particularly, to a movement amount gauge for supporting a bridge and a bridge support provided with the movement amount gauge.

Generally, the bridge is provided with a support, which is a supporting device, at the boundary between the upper structure and the lower structure to transmit the force received from the upper structure to the lower structure. (Movable point) that moves the upper structure smoothly to the lower structure. The movable support has a one-directional support which is operated only in the left and right direction, and a movable support in the left, right, There is a bi-directional pedestal that operates.

Among these, the movable support is required to have a structure that smoothes the movement of the bridge by the temperature change, the drying shrinkage, the creep and the like of the steel material or the concrete which is the upper plate structure, and there are metal supports and rubber supports.

The above-described movable support is moved (stretched or shrunk) by a bridge such as an increase or decrease in the upper structure of the bridge depending on various external conditions (temperature change or vibration). Accordingly, .

That is, since the lower end of the support is coupled and fixed to the lower structure of the bridge, and the upper end is fixedly coupled to the upper structure of the bridge, the upper end of the support moves as the upper structure of the bridge is expanded and contracted.

Such an expansion and contraction of a bridge is subject to inspection at the time of safety inspection of a bridge, and a measurement system is installed on the support to measure the expansion and contraction.

1 shows a state in which the measurement system is installed on the bridge support 20. In FIG. The measurement system includes a measurement plate 11 on which a scale is printed and an indicator 12 formed on the top of the body 13 for indicating a scale printed on the measurement plate 11, And a measuring needle 19 indicating a graduated scale printed on the screen 11.

When the measurement system is installed on the bridge support as described above, the upper plate of the bridge is expanded and contracted due to climatic conditions, traffic volume, etc., and the measurement plate 11 moves together when the upper plate of the bridge support 20 is moved to the left or right. As a result, the state in which the indicating needle 14 of the indicator 12 indicates the central portion of the scale printed on the measuring plate 11 is changed to indicate the left or right side from the center of the scale, 18 are also changed in position by the indicator needle 14.

When the upper side of the support 20 is returned to its original state, the indicator needle 14 again points to the center of the scale, but the measurement tool 18 is not returned to the original position and is located at the position shifted to the outside. The value read from the scale indicated by the measuring needle 19 of the measurement port 18 becomes the maximum value at which the bridge is expanded and contracted.

Therefore, when the bridge is inspected, the reading of the scale indicated by the measuring needle 19 of the measuring instrument 18 is read and recorded, and then the measuring instrument 18 is artificially returned to its original position.

However, according to the conventional technique, it is very useful to measure the amount of displacement at the time of full-scale displacement. However, when the amount of displacement exceeds the constant displacement, the amount of displacement can not be measured or tracked.

FIG. 2 is a front view showing a state in which a movement amount gauge according to an embodiment of the present invention is installed on a bridge support, and FIG. 3 is a partial cross-sectional view for explaining a configuration of a movement amount gauge according to an embodiment of the present invention.

The movement amount gauge 100 for supporting a bridge according to an embodiment of the present invention is installed in a bridge support 200 composed of an upper plate 210, a lower plate 220 and an elastic body 230, And a stopper protrusions 140a and 140b, a left side moving body 130a and a right side moving body 130b and a guide 150 around a gage main body 120 provided with a gage main body 120, Even when the amount of movement of the structure SB exceeds the constant displacement and exceeds the limit of the area of the scale 121, the left moving body 130a and the right moving body 130b are pushed by the pointer 150, Displacement to earthquake displacement (hereinafter referred to as "intermediate displacement"), and earthquake displacement order.

Hereinafter, the movement amount gauge according to the embodiment of the present invention will be described in detail with respect to each of the above components.

The main body is attached to the side of the upper plate 210 of the bridge support at the upper side corresponding to the guide 150 and the movement amount at the time of the full displacement of the bridge upper structure SB is measured by the guide 150 (Not shown). In addition, the gauge body 120 is provided with a guide hole 120a passing through the body in the left and right directions, so that the left and right movable bodies 130a and 130b can be slidably moved forward and backward. Here, the gage main body 120 is made of a material so that it can be easily attached to and detached from the upper plate 210 of the bridge support.

The left moving body 130a is installed so as to be able to move forward and backward in a state where it is inserted into the guide hole 120a from the left side of the gage main body 120 and moves along the guide hole 120a of the gage main body 120 And a locking part 131a protruding downward from an end of the sliding part 132a so as to be hooked on an upper end of the guide 150. The sliding part 132a has a sliding part 132a, Such a left side moving body 130a is provided with the guide 150 when the relative displacement amount of the guide 150 exceeds the area of the scale 121 of the gage main body 120 to the left (exceeding the constant displacement of the bridge overhead structure) ) To the left to indicate the amount of left movement exceeding the normal displacement of the bridge superstructure.

The right side moving body 130b is provided so as to be able to move forward and backward in a state where it is inserted into the guide hole 120a from the right side of the gage main body 120. In the same way as the left side moving body 130a, A sliding part 132b which moves along the guide hole 120a and a locking part 131b which protrudes downward from the end of the sliding part 132b and is hooked on the upper end of the guide 150, . Such a right side moving body 130b is provided on the right side of the guide 150 when the relative displacement amount of the guide 150 exceeds the area of the scale 121 of the gage main body 120 to the right (in case of exceeding the constant displacement of the bridge overhead structure) ), And moves to the right side to indicate the rightward movement amount exceeding the normal displacement of the bridge superstructure.

The top plate 110 is installed on the gauge body 120 with a wide width relative to the gauge body 120 as shown. In the case of the top plate 110, it is preferable that the top plate 110 is integrally formed with the gage main body 120. However, the top plate 110 may be provided as a separate entity and attached to the upper plate 210 of the bridge support.

The stopper protrusions 140a and 140b protrude downward at left and right ends of the top plate 110, respectively. When the stopper protrusions 140a and 140b are installed, the left and right movable bodies 130a and 130b are abruptly pushed by the guide 150 when the bridge upper structure is seismically displaced, and the stopper protrusions 140a and 140b It is possible to indicate that a seismic displacement exceeding the intermediate displacement between the normal displacement and the seismic displacement has occurred.

The guide 150 is installed on the side of the lower plate 220 of the bridge support and is formed in a shape elongated so as to extend to the gage main body 120 so that the guide can be pointed to the scale 121 So that the left and right movable bodies 130a and 130b can be moved.

According to such a configuration of the moving amount gauge, when the bridge overhead structure SB is constantly displaced, the guide 150 is relatively moved in the area of the scale 121 provided in the gauge body 120 so that the displacement amount can be measured do. However, if the bridge superstructure SB exceeds the normal displacement, the movement of the left movable body 130a and the right movable body 130b, which advance by pushing by the pointer 150, And when the seismic displacement is reached, the left moving body 130a and the right moving body 130b are separated by the stopper protrusions 140a and 140b to track whether the seismic displacement occurs. In the following, such operation will be described in more detail using the attached drawings.

FIG. 4 is a view for explaining the operation of the movement amount gauge according to the embodiment of the present invention, and FIG. 5 is a view showing the operation of the movement amount gauge during the middle displacement between the normal displacement and the earthquake displacement according to the embodiment of the present invention 6 is a reference diagram for explaining an operation of the movement amount gauge according to the embodiment of the present invention at the time of earthquake displacement.

Fig. 4 shows the operation of the movement amount gauge when the bridge superstructure SB is constantly displaced. When the bridge superstructure SB is constantly displaced, the guide 150 is moved only in the area of the scale 121 of the gauge body 120. Since the left movable body 130a and the right movable body 130b are not touched, The advance operation of the right side mobile body 130a and the right side mobile body 130b does not occur. At the time of such full-time displacement, the state returns to the original state (c) through the displacement state (b) where the normal displacement occurs in the initial state as shown in FIG. 4 (a). Since this is an extremely normal situation, it is practically not necessary to track the movement amount through the movement amount gauge according to the embodiment of the present invention.

5 shows the operation of the movement amount gauge when the bridge superstructure SB exceeds the normal displacement and is displaced midway between the normal displacement and the earthquake displacement. When the bridge superstructure SB is excessively displaced in such a manner as to be excessively displaced in such a manner as to be displaced in such a manner as to be displaced in the normal direction, ). As a result, the left-side moving body 130a and the right-side moving body 130b advance (the left-side moving body 130a moves). In the intermediate displacement, as shown in (a) of FIG. 5, when the movable body 130a and the right movable body 130b advance from the initial state to the original state (c) through the displacement state (b) It remains that way. As a result, it can be understood that even though the normal displacement of the bridge overhead structure SB has been exceeded through the left movable body 130a and the right movable body 130b which have remained in the advanced state, no earthquake displacement has occurred.

Fig. 6 shows the operation of the movement amount gauge when the bridge superstructure SB reaches the seismic displacement beyond the normal displacement and the intermediate displacement. When the bridge superstructure SB exceeds the normal displacement and reaches the seismic displacement exceeding the intermediate displacement, the guide 150 excessively pushes at least one of the left mobile body 130a and the right mobile body 130b, The moving body pushed by the pointer 150 among the left and right movable bodies 130a and 130b is broken while being caught by the stopper protrusions 140a and 140b. At the time of such earthquake dislocation, at least one of the left-side moving body 130a and the right-side moving body 130b is returned to the original state (c) through the displacement state b in which the earthquake displacement occurred in the initial state as shown in FIG. 6 One remains broken. Thus, it can be understood that the seismic displacement far exceeding the steady displacement of the bridge overhead structure SB has been generated through the left movable body 130a and the right movable body 130b which are left in the broken state, and measures can be taken accordingly .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It is clear that the present invention can be suitably modified and applied in the same manner. Therefore, the above description does not limit the scope of the present invention, which is defined by the limitations of the following claims.
