Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an apparatus for measuring a shear deformation of a bridge,

The present invention relates to the measurement of the amount of shear deformation of an elastic support, and more specifically, when an elastic bearing installed at a lower portion of a bridge is deformed according to expansion and contraction of a bridge, a distance measuring laser and an inclination meter are used to measure a shear deformation The present invention relates to an apparatus for measuring a shear deformation amount of a bridge elastic support,

In general, construction of construction structures requires seismic design to prevent damages such as earthquakes and increase lifetime of structures.

Especially, in the case of bridges, there is a concern about structural damage due to the earthquake damage, so it is necessary to design and strengthen the seismic reinforcement in order to secure the stability. These bridges consist of an upper structure directly supporting the load by a vehicle or the like moving on the upper part, and a lower structure such as an alternating or piercing bridge for supporting the upper structure.

Between the superstructure and the lower structure of these bridges, the vertical load acting on the upper structure is accommodated, and the relative displacement due to seasonal temperature changes, wind, earthquake, etc. or the shear displacement acting horizontally is accommodated, Elastic bearings are installed to extend the service life. These elastic supports are installed considering durability, workability, maintainability and economical efficiency though there is a difference according to the characteristics of bridges.

FIG. 1 is a view showing a state in which a resilient support for a bridge according to a conventional technique is installed on a bridge, and FIG. 2 is a side view showing a state in which a resilient support for a bridge is deformed according to a conventional technique.

As shown in FIGS. 1 and 2, the elastic support 10 for a bridge according to the prior art has elasticity provided between the lower plate 11, the upper plate 12 and the upper and lower plates 11 and 12, And a pad (or a rubber pad) 13. The elastic support 10 having such a configuration is installed between the lower structure 1 and the upper structure 2 of the bridge. That is, the upper plate 12 of the elastic support 10 is fixed to the upper structure 2 side, and the lower plate 11 is fixed to the lower structure 1 side. Here, the elastic pad 13 has a structure in which the rubber 13a and the inner reinforcing plate 13b are sequentially stacked in layers.

When the vertical load acts on the elastic support 10, the rubber 13a inside the elastic pad 13 expands. At the same time, the inner reinforcing plate 13b suppresses the expansion of the rubber 13a, The vertical load is suppressed by increasing the load-bearing capacity of the rubber. When the elastic support 10 is horizontally displaced, the rubber 13a is elastically deformed to absorb the displacement, and even when the elastic support 10 receives rotational displacement, the elasticity of the rubber 13a, It accepts the acting force.

However, when the horizontal displacement occurring in the bridge is repeated for a long time, the fatigue of the bonding portion accumulates, and the edges where the reinforcing plate 13b and the rubber 13a are bonded are peeled off. As a result, Is deformed or broken, the function of the elastic support 10 is lost, which hinders the safety of the bridge and shortens the durability life.

In addition, the elastic support 13 for a bridge deforms as the bridge is expanded or contracted due to temperature or the like. For example, as shown in FIG. 2, when the bridge shrinks, the plate material stacked on the elastic support 13 moves in the direction in which the bridge shrinks. As a result, It is deformed in the contraction direction.

In this case, there is no particular problem when the elastic support 13 is deformed within the range of the elastic limit. However, if the elastic support 13 is deformed to the extent that it exceeds the elastic limit, a problem occurs. That is, if the elastic support 13 is deformed to the extent that the elastic limit exceeds the elastic limit, the restoring force is lost, and if it is severe, the elastic support 13 tears and the bridge can not be supported properly. A problem may arise.

) 등이 있다.Therefore, the amount of deformation of the elastic support 13 should be periodically measured. If it is determined that the elastic support 13 has reached the elastic limit, the elastic support 13 must be replaced or a repair operation must be performed. The amount of deformation to be measured for this purpose is determined by the distance L between the upper end of the elastic supporter 13 and the inclination of the elastic supporter 13

).

In order to measure the amount of deformation of the elastic supporter 13, a worker has conventionally measured the tape 11 at the bottom of the bridge 11 using a tape measure for measurement. In the conventional tape measure, It is difficult to perform the operation and it takes a lot of time. Further, there is a problem that it is very difficult to measure the degree of tilting of the elastic support 13. In addition, safety and convenience are inferior in view of the working environment, various measuring members are required, and the risk of loss is large, and it is difficult to carry.

On the other hand, as a prior art, Korean Patent Publication No. 2000-347 discloses an invention entitled "Bridge Support Extension Measurement System ", which will be described with reference to FIG.

[ A measuring needle inserted into the measuring instrument insertion groove formed at the lower end of the measuring plate 21 is provided with a measuring needle 26 for indicating a scale printed on the measuring plate 21 at the upper end.

In the case of the bridge support stretch measuring system 20 according to the conventional art, a measuring system installed in the elastic support 10 of a bridge to measure elongation and contraction of the bridge is used as a maximum value at which the bridge can stretch and contract And it is possible to quickly determine the maintenance of the bridge since it is possible to check the installation date, capacity, installation position and installation temperature of the bridge resilient support 10 at the bridge inspection site.

Especially, when the elastic support 33 is deformed using the protractor 80,

) Must be measured.

Recently, a system for measuring the amount of deformation by installing a sensor on the support of a bridge has been applied. However, considering that it must be installed for each of a plurality of piers, installation cost and management cost are excessively required, There is a problem.

As described above, according to the conventional technique, a measuring device such as a triangle according to the height of the elastic pad can be changed from time to time, and there is a high possibility that an error will occur depending on the position of the investigator when measuring the amount of shear deformation. There is a problem that the measurement time is increased.
