Description

Deformation measurement and inspection device of elastic bearing for bridge

The present invention relates to a deformation measuring and checking apparatus of an elastic bearing for a bridge, and more particularly, a bridge for measuring the deformation easily or accurately when the elastic bearing or the upper plate, etc. installed in the lower portion of the bridge is deformed according to the stretching of the bridge. The present invention relates to an apparatus for measuring and checking deformation amount of elastic bearings.

In general, when constructing an overpass or a long bridge, the superstructure is installed on the substructure according to the temporary construction method, and the construction of the concrete is performed after installing the formwork, the support, the fall prevention net, the work scaffold, and the traffic control fence. It is constructed using the site concrete placing method that completes the superstructure after the casting and curing process.

Here, the bridge is a superstructure that the vehicle directly runs, the substructure installed to support the superstructure, and transfer the load of the superstructure to the substructure between the superstructure and the substructure and absorb the expansion and contraction of the superstructure by the temperature It consists of an elastic bearing installed for

In this bridge structure, the most important factor that affects the safety of the bridge is the elastic bearing. In addition, since the elastic support moves in and out according to external temperature change, drying, and shrinkage, the amount of movement of the elastic support is inevitable.

When the elastic bearing moves, it causes a crack in the superstructure and generates a tangential force in the tangential direction to the substructure on which the bearing is installed, thereby causing the shear (punching) destruction of the concrete.

In other words, if the elastic bearing is deformed within the elastic limit, no special problem occurs, but if the elastic bearing is deformed beyond the elastic limit, the elastic bearing loses its restoring force and, in severe cases, the elastic bearing is torn. The bridge cannot be supported properly, resulting in structural problems in the bridge.

Therefore, the elastic bearings for bridges should be periodically measured for deformation, and if the elastic bearings are determined to be close to the elastic limit, the elastic bearings should be replaced or repaired. In this case, the amount of deformation to be accurately measured in order to measure the elastic limit of the elastic bearing is the distance at which the upper end of the elastic bearing is deformed and the inclination of the elastic bearing.

In order to measure the amount of deformation in the prior art, the operator measures manually by using a measuring tape under the bridge. The measurement tape is not only difficult to measure the amount of deformation accurately, but also it is not easy to work and the time required for the measurement. There is a problem that is required a lot, moreover, because it measures at the top of the bridge requires a number of safety measures to ensure the safety of the operator and difficult to work due to the uncomfortable posture for the operator to measure the deformation amount even when the safety means are provided There was this.

In order to guarantee the safety of the worker and to facilitate the measurement of the deformation of the elastic bearing, a system for measuring the deformation by installing a sensor on the elastic bearing of the bridge has been proposed. This is excessive and there is a difficulty in maintaining the strain measurement system including the sensor normally.
