Description

The sag measuring device of a bridge or a high-level road}

The present invention relates to a device for measuring the deflection of the upper plate, such as a bridge (bridge) or high-level road, and is easy to install and dismount through the light weight and mechanization of the measuring device, as well as excellent portability In addition, it is useful to shorten the measurement time together with precise measurement.

In general, bridges and high-level roads, etc. are built under a continuous load as vehicles pass through for a long time after construction, in particular, the bridge top plate is caused by repeated operation of the overload vehicle In addition, fatigue phenomenon of the top of the legs due to the overload shortens the life of the legs and even includes the risk of large safety accidents in which the bridge collapses due to accumulated fatigue, so regular safety checks are required.

As a part of such safety diagnosis, the degree of deflection of the upper leg plate 2 installed on the pier 1 is measured and used as a safety diagnosis data of the leg. FIG. 1 shows a conventional deflection using a scaffold to measure the deflection of the upper leg plate. The measurement method is shown.

In general, when a moving load acts on the leg, the maximum bending moment and the maximum deflection occur at a point half of the bridge span, and the deflection measurement of the upper plate 2 is usually performed here.

In order to measure the deflection of the leg top plate 2, the scaffold pedestal 3 is piled up in multiple stages to fit the height of the leg to be measured, and then the operator's answer plate is installed at the top of the scaffolding, and the bottom of the leg top plate is placed on the scaffold column. After fixing the vertical column close to the, measure the amount of deflection by installing a deflection meter (4) on the top of the vertical rod, and the measured amount of deflection is analyzed by the record analysis device (6) installed on the workboard to determine whether the legs are safe or not. Has been diagnosed.

However, this conventional leg upper plate (2) deflection measuring device must be assembled and installed in accordance with the height of the legs of the prefabricated iron scaffold base (3) in the field, because the weight and volume of the iron scaffold itself is considerable, it is carried And a considerable cost is required for installation, it takes a considerable time to stack and assemble the scaffold pedestal (3) in multiple stages, there is a problem that slow work.

In addition, it is not easy to vertically install the deflection meter 4 on the scaffold pedestal 3 located at the top and maintain the vertical state, which may cause inaccurate results. In order to read, the operator must climb on top of the scaffold pedestal 3 or dismantle the pedestal 3 to read it. Therefore, safety problems and measurement time are taken for a long time and it is difficult to obtain accurate results. There is a problem, and in addition, concern about settlement of the scaffold itself cannot be excluded.

The present invention solves the conventional problems as described above, and is easy to install and release through the light weight and mechanization of the measuring device, easy to carry and excellent in mobility, as well as precision measurement and shorten the measurement time with the bridge or elevated road It is an object of the present invention to provide a device for measuring deflection.

That is, the triangular lower base part and the height adjusting device part having a screw shaft rod, and a measuring device part on the prefabricated pole part connecting the unit pole by the height of the leg, and the code line is drawn out from the ground recording analysis device. By having a connected structure, the weight and weight of the scaffold base are significantly reduced compared to the conventional weight and bulky scaffold, and the assembly and disassembly of each component is very simple. Due to the purpose of the present invention is very excellent in mobility.

In addition, by assembling the unit pole by the height of the leg to be measured, and fixing the deflection meter vertically to the top pole, the cord line touching the lead is pulled out by a cord drawer and connected to a recording analysis device on the ground. Another object of the present invention is to accurately measure the deflection of the upper leg of the leg, and to prevent a worker's safety accident.

In addition, it is easy to install and release the measuring device, and the recording and analyzing device can be installed close to the height of the bridge, and after the measuring device is released, the analysis can be performed directly on the ground without the hassle of reading from the ground. Maximization is another object of the present invention.
