Abstract

The present invention relates to a safety diagnosis device for bridge deck expansion joint detection. The safety diagnosis device can significantly reduce measurement errors by maintaining a rod of a potentiometer without a change in length even when a bridge deck moves downwards, moves in the direction perpendicular to a throttle, or moves downwards in the direction perpendicular to the throttle at the same time and can prevent accidents such as bridge collapse in advance by estimating the service life and safety of a bridge by a result value and easily determining a maintenance point of time.

Description

[0001] The present invention relates to a safety diagnosis apparatus for bridge connection,

The present invention can output accurate measured values because the load of the potentiometer maintains the current state without changing the length regardless of whether the bridge top plate moves downward or moves in the direction perpendicular to the throttling axis or moves simultaneously in the direction perpendicular to the throttling direction It is possible to greatly reduce the measurement error and predict the durability life and safety degree of the bridge through the result, so that the maintenance point can be determined easily, so that the bridge such as the collapse of the bridge can be prevented in advance. ≪ / RTI >

In the case of bridges commonly used for road structures, a number of bridging roofs are arranged in the longitudinal direction of the front and rear, and the connecting portions of the bridges are compressed and expanded due to the atmospheric temperature difference due to seasonal changes Or the left and right widths are irregularly moved by an external force.

Therefore, this change greatly affects the life or strength of the bridge. Therefore, it is necessary to check and check the facility manager from time to time to check whether there is an abnormality in the bridge. It is necessary to check the facility manager from time to time, It has been pointed out that ancillary problems due to accident risk and vehicle control have been pointed out.

In order to solve such a problem, the registered utility model No. 265797 entitled " Measurement system for safety diagnosis of road structures and bridges " is well known.

The above-mentioned " measurement system for safety diagnosis of road structures and bridges " is briefly described as follows. A scale plate, which is installed in a space between upper plates and has a graduation on its surface, is fixed in the longitudinal direction of the bridge, The measuring pin having the indicator needle is fixed in the longitudinal direction of the bridge with the fixture on the end side surface of the other upper plate while the scale plate and the indicator plate are positioned in the upward and downward directions to check the scale of the indicator indicated by the indicator needle The amount of displacement of the bridge, that is, the amount of expansion and contraction can be measured.

Korean Patent No. 10-0942060 discloses a bridge having a bridge for preventing departure of a bridge top plate. In brief, a first axis and a second axis provided with an angle sensor are fixed to an upper plate, respectively, , An air spring is fixed to both ends of the shaft, a pressure sensor is provided inside the air spring, and the control unit receives the measured values from the angle sensor and the pressure sensor and transmits the measured values to the output unit.

The above-mentioned prior art has a very advantageous advantage because it can easily measure the separation of the bridge top plate and confirm the safety of the bridge on the basis of the measured data.

However, in the case of the conventional art, when the bridge top plate is moved or moved in the direction perpendicular to the throttling axis, the distance between the bridge top plates does not actually change, but the length of the air spring changes correspondingly, Which can lead to misleading confusion of the bridge manager, and there is a fundamental serious problem in that the error is also considerably large and the measurement reliability is significantly lowered.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems and it is an object of the present invention to provide a potentiometer in which the load of the potentiometer can be changed without changing the length regardless of whether the bridge top plate is moved downward or in a direction perpendicular to the throttling axis, Since it maintains the current state, accurate measurement value can be outputted, and the measurement error can be greatly reduced.

Therefore, there is no need to forcefully separate the adhesive mount 20 from the bridge top plate, the bridge, or the alternation, and the damage (breakage) to the bridge can be prevented.

12, the first and second vertical support rods 10 and 10 'are abutted against the adhesive mount 20 via the bracket BK inserted and fixed at the end thereof, and are detachable via the fastening bolt B .

According to the present embodiment, since the first and second vertical support rods 10 and 10 'and the adhesive type bracket 20 are fixed via the bracket BK, the installation and disassembly are considerably convenient and the time can be shortened, There is no need to separate the adhesive mount 20 from the bridge top plate, the bridge, or the alternation so that damage (breakage) to the bridge can be prevented.

13, the adhesive mount 20 is provided with a coupling portion 27. The ends of the first and second vertical support rods 10 and 10 'are inserted into the coupling portion 27, respectively, B).

The shape of the engaging portion 27 may be deformed as much as possible depending on the end shape of the first and second vertical supports 10 and 10 '.

According to the present embodiment, since the ends of the first and second vertical support rods 10 and 10 'are mutually coupled through the fastening bolts B in a state where the end portions of the first and second vertical support rods 10 and 10' are inserted into the coupling portion 27 of the adhesive- It is possible to solve the problem of easily separating even if an external force acts, and furthermore, the installation and disassembly can be considerably simplified and the time can be shortened, There is no need to separate the bridges from the bridges or the bridges, or the bridges can be prevented from being damaged (broken).

FIG. 14 is a perspective view of a magnetic base according to a second embodiment of the present invention. FIG.

Note that in the present embodiment, a magnetic base 20 'is applied to the first and second vertical support rods 10 and 10' instead of the adhesive type attachment rods 20 so that the first and second vertical support rods 10 and 10 ' I hope.

The magnetic base 20 'is a mechanism having a strong magnetic force device at the bottom, and is also referred to as a magnet type bottom portion.

As shown in FIG. 14, the magnetic base 20 'is formed in a rectangular box shape as a whole, and an operation lever 21' for ON / OFF control of magnetic force generation is provided on the outer surface, And a fastening portion 22 'to which a fastening bolt B formed at one end of the support rods 10 and 10' is detachably coupled.

According to the present embodiment, when at least one of the magnetic bases 20 'is applied to the first and second vertical supports 10 and 10' instead of the adhesive mount 20, It is not necessary to separately prepare or carry the adhesive (FX) and it is convenient. Since it is possible to install it immediately without having to wait until the adhesive (FX) hardens, the release time can be drastically shortened as well as the installation time. It can be installed and released more even at the same time, and there is an advantage that it is possible to maintain the bridge as it is because the attachment part (adhesive installation stand) is not left.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims. .
