Description

A bridge device abutment for bridge expansion and contraction abnormal noise department}

The present invention relates to a bridge having a bridge for preventing the separation of the bridge deck, which is respectively mounted on the bridge deck to easily measure the separation between the bridge decks and to confirm the safety of the bridge based on the measured data.

In general, in the case of bridges used for road structures, a plurality of bridge decks are arranged in the longitudinal direction of the front and rear sides, and the bridges of the bridges are compressed and expanded due to the air temperature difference according to the seasonal change. Or the left and right widths are irregularly flown by the external force.

Therefore, this change affects the life and strength of the bridge a lot, so the facility manager should check and check the bridge at any time to check whether there is an abnormality. Incidental problems due to accident risk and vehicle control have been pointed out.

Briefly describing the "measurement system for safety diagnosis of road structures and bridges", a scale plate installed in the space between the upper plates and a scale marked on the surface is fixed in the longitudinal direction of the bridge as a fixture on the end side of one upper plate. While the measuring pin with the indicator needle on the part is fixed in the longitudinal direction of the bridge as a fixture on the end side of the other upper plate, the scale plate and the indicator plate are positioned in the up and down directions to check the scale of the scale plate indicated by the indicator needle. Therefore, the displacement amount of the bridge, that is, the configuration is made to be able to change the amount.

However, the "safety diagnosis measuring system for road structures and bridges" must be managed from time to time because the operator must go to the site and check the scale directly, and the accurate reading of the bridge displacement can be obtained by measuring the displacement amount by visual identification. It is difficult, and the front and rear displacement of the bridge deck can be known, but the left and right changes are not known at all.

Therefore, the present invention was devised to solve the above problems, the pressure sensor and the angle sensor to detect the movement of the bridge top plate flowing back and forth and left and right to express the numerical value in the output unit through the control unit facilities manager bridge The aim is to provide bridges with bridges to prevent departures from bridge decks that do not require frequent checks.
