When displacement occurs in the cantilever section of the footbridge for various reasons, such as, a third fastening part for fixing and installation on the lower surface of each pipe installed in the longitudinal direction of the bridge at the end of the upper surface of the sub-girder and the floor The measurement solution in a fixed state between the fourth fastening parts for fixed installation on the lower surface of each pipe installed on the lower surface of the central part of the plate is inclined to one side, and accordingly, the measurement solution contained in the measurement solution made of a transparent body is on one side. The inclined inclination is displayed on the scales displayed on both ends of the measurement solution as it is tilted toward, and accordingly, the sag sensor unit, which is attached to the inner side of the scale, and is immersed in the measurement solution is displaced due to the deflection of the footbridge, As it is tilted to one side, when the height of the measurement solution is positioned lower than the sag sensor unit, a signal is sent to the manager computer connected thereto, and the manager recognizes it and induces the manager to implement a countermeasure. Even if the signal is transmitted between the sensor unit and the computer in real time, it is difficult to immediately warn of sagging, so the risk of a fall is high, and there is a risk of personal accidents due to the fall.

The railing post 13 and the railing rod 15 are elements constituting the railing.

The bridge inspection facility 10 of the present invention includes a displacement notification device to be described later, and the displacement notification device is a fixed post 11 that is separated when the fixed post 11 is separated (the upper part falls earlier than the lower part). An alarm system (audible guidance) for outputting an alarm sound by the lower bracket 12 when the lower bracket 12 is tilted away from the fixed post 11 and/or outputs an alarm sound by , When the fixed post 11 is detached (the upper part falls earlier than the lower part), it is spread on the detached fixed post 11 and displays a danger phrase (visual guidance) (Example 2), each implementation Examples are described in detail below.

As a bridge inspection safety facility, the bridge evacuation facility also includes the features of the above-described bridge inspection facility 10.

<Example 1>

As shown in FIGS. 2 and 3, the displacement notification device of the bridge inspection safety facility according to the present embodiment generates an alarm sound by the air type alarm 20 and the air type alarm 20 using a fixed post 11 The post reinforcing plate 50 and the lower bracket 12 are used as a switch operating member for operating the upper switch 30 and the lower switch 40, and the upper switch 30 and the lower switch 40. ).

The air alarm 20 is composed of an upper switch 30 and a lower switch 40 while the compressed air is filled therein, and the upper switch 30 and the lower switch 40 are opened to It outputs an alarm sound by discharging the compressed air from the outside.

The air type alarm 20 may be an air tube itself, but by using the structure of the fixed post 11, it is configured as follows so as to prevent damage without discomfort.

First, the fixed post 11 of the bridge inspection facility 10 is usually a square tube with open both sides in the longitudinal direction, and covers the open part of the fixed post 11 to form an air chamber that is disconnected from the outside inside, and the upper switch 30 ) And the lower switch 40 constitute the air alarm 20. In addition, in the air type alarm 20, the internal compressed air may be lost over time, and the sound of the alarm sound is small when the compressed air is lost, so that the alarm for safe evacuation cannot be made. ), an injection unit 21 for replenishing compressed air and a pressure gauge 22 for checking pressure may be configured.

The air type alarm 20 uses the fixed post 11 itself as a chamber to directly inject compressed air into the fixed post 11, and the method of storing an air bag filled with compressed air in the fixed post 11 It is possible.

The air-type alarm 20 is an audible alarm and is filled with color powder to enable a visual alarm, so that the color powder is discharged to the outside when the compressed air is discharged, so that a visual alarm can also be provided.

The upper switch 30 and the lower switch 40 allow an alarm sound to be output in accordance with different departure states of the bridge inspection facility 10 through their installation positions, and the upper switch 30 is a fixed post 11 ) To output an alarm sound when it is separated, and the lower switch 40 to output an alarm sound when the lower bracket 12 is separated.

The upper side switch 30 and the lower side switch 40 applied to the air type alarm 20 block the inside of the air type alarm 20 from the outside to prevent the discharge of internal compressed air. ) Is a valve switch that allows the inside and outside of the air alarm 20 to communicate with each other when the switch operation member is operated so that compressed air is discharged to the outside.

Depending on the positions of the upper switch 30 and the lower switch 40, various departures of the bridge inspection facility 10 can be reported. For example, the upper part of the fixed post 11 rotates and the anchor 2 is separated. It can be notified that the fixed post 11 goes down, the lower bracket 12 is separated from the fixed post 11 while rotating, and the lower bracket 12 goes down.

In the drawing, the upper switch 30 and the lower switch 40 are disposed on the air alarm 20, and are positioned to notify that the upper part of the fixed post 11 is separated from the anchor 2 while rotating. As an example, it is shown that the lower bracket 12 is installed at a position indicating that it is going down.

As a switch operating member of the upper switch 30, the post reinforcing plate 50 also functions as a reinforcement to prevent the fixing post 11 from being separated from the anchor 2 while opening the upper switch 30. , The structure is an anchor fixing part 51 fixed with a bolt 54 fastened to the anchor 2, an inclined part 52 that is bent forward from the anchor fixing part 52, and the lower end of the inclined part 52 It is formed to extend toward the lower portion of the post is composed of a support combined operation portion 53 overlapping in front of the fixed post (11).

The bolt 54 is applied to the bridge inspection facility 10 and may be an eye bolt that fixes the safety wire 16 on which the safety hook of a worker is caught. The safety wire 16 is inserted into a bolt 54 that fixes the fixing post 11 of the bridge inspection facility 10 to the bridge 1 and is wired along the bridge inspection facility 10.

Post support combined operation unit 53 may be configured with a hole in the central portion so as to overlap the wing portion in accordance with the structure of the fixed post 11 consisting of a square tube portion and the wing portions on both sides, of course, but not limited to the above It is also possible to be configured so as to overlap each pipe portion, and may also include a bolt for pressing the fixing post (11).

The post support combined operation part 53 is arranged to be attached to the front of the wing part of the fixed post 11 in a state where the bridge inspection facility 10 is not separated, and this position is the rear of the upper switch 30, that is, the upper part. It is a switch operation part.

Therefore, when the fixed post 11 is separated, the post reinforcing plate 50 maintains the anchor fixing part 51 fixed to the anchor 2, but the fixed post 11 moves the post support and operation part 53 forward. As a result, the post support combined operation part 53 pushes the upper switch 30 to open it.

The switch operating member corresponding to the lower switch 40 is the lower bracket 12 of the bridge inspection facility 10.

In the drawing, the lower switch 40 is disposed at the bottom of the lower bracket 12 and is opened by the lower bracket 12 when the lower bracket 12 sags.

The upper switch 30 and the lower switch 40 are types that return to their original positions when the restraint of the switch operation member is released.

6 shows another example of the switch operation member of the lower switch 40, the lower switch 40 is disposed on the upper side of the lower bracket 12, the switch operation member is the upper surface of the lower bracket 12 It is a sensor bracket 41 that is fixed to (bolted, etc.) and connected to the lower switch 40. The sensor bracket 41 is a horizontal portion fixed to the lower bracket 12 and a vertical portion having a hole through which the lower switch 40 extends vertically from the horizontal portion in the same direction as the square pipe of the fixed post 11. It is made, and when the lower bracket 12 sags downward, the vertical portion operates the lower switch 40.

The post support and operation part 53 of the plate 50 is pushed, and the post support and operation part 53 pushes the upper switch 30, and thus, the air type alarm ( As the compressed air filled in 20) is discharged, an alarm sound is generated by the air discharge.

The worker in the bridge inspection facility 10 hears this alarm sound and confirms that it is above the safe load and moves to another place to disperse the load or evacuate to a safe place.

2. Notification when lower bracket sags.

When the load is concentrated on the bridge inspection facility 10 and the lower bracket 12 sags downward, as shown in FIG. 5, the lower bracket 12 operates the lower switch 40 to compress the air alarm 20 An alarm sound is generated while air is discharged, and the operator hears the alarm sound and evacuates or disperses.

In this way, when the load due to the movement or evacuation of the worker is reduced to a safe load, the fixed post 11 of the bridge inspection facility 10 returns to the initial installation position and falls from the upper switch 30, and the lower bracket 12 Since the air type alarm 20 is closed by falling from the lower switch 40, the output of the alarm sound is stopped.

<Example 2>

7 to 9, in this embodiment, the displacement notification device of the bridge inspection safety facility is a ringing type alarm in which a spring (spring spring) type striking member continuously strikes the ringing tube to generate a sound.
