Abstract

[TECHNICAL FIELD]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a building and a tilt determination device for a bridge that measures inclination of a building and a bridge.

[Technical Problems to be Solved]

The slope of a conventional building or bridge can be measured by an alcohol level and a laser interferometer. However, the method using the alcohol level stage was made small in level and the size of the air bubble displayed was relatively large, so that the error due to the observer was considerably contained. In addition, although the latter measurement is more accurate than the laser interferometer, most of the apparatuses are expensive, which is not practical.

[The point of the solution]

The present invention can reduce the measurement error caused by the observer while making the outer shape of the measuring device large, while reducing the size of the measuring device, and enable measurement with high precision, and a simple structure can be provided at a low cost to be practically used.

[Use of the invention]

Determination of slope of buildings and bridges.

Description

Slope determination device of buildings and bridges

The present invention relates to a tilt determination device for buildings and bridges that measures tilting of buildings and bridges. More specifically, the present invention relates to a tilt determination device for a tilt of a building and a bridge by simply and precisely tilting the tilt due to natural settlement and artificial settlement To the measuring device.

The slope of a conventional building or bridge can be measured by an alcohol level and a laser interferometer. However, the method using the alcohol level stage was made small in level and the size of the air bubble displayed was relatively large, so that the error due to the observer was considerably contained. In addition, although the latter measurement is more accurate than the laser interferometer, most of the apparatuses are expensive, which is not practical.

In addition, according to the Act on Facilities Safety Management (Article 6 of the Special Law and the Enforcement Decree of the Enforcement Decree of the Enforcement Decree of the Special Act), daily inspections are prescribed once a quarter and regular inspections are conducted once every three years. However, since it is impossible to measure a precise slope due to the disadvantage of a simple measuring instrument, there is a problem in that it is limited to the actual type.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and it is an object of the present invention to provide a measuring instrument with a large external shape, a small indicator, a small measurement error by an observer, And it can be practically used.

The tilt determining device 1 shown in FIGS. 1 and 2 is an embodiment of the present invention. In order to facilitate visibility and judgment, the tilt determining device 1 is a semicircular tube having a diameter of about 300 mm or more, And a conical indicator 5 fixed to the upper end of the chamber 4 suspended at the center of the inner bottom surface of the container 2 is installed so as to stand vertically in a direction perpendicular to the horizontal plane A pressure regulating device 9 composed of a blocking plate 6 for blocking the flow of the antifreeze 3, a spring 7 for pressing the blocking plate 6 and an elastic adjusting bolt 8 is provided at the bottom of the outer surface of the container 2, A slope display scale 10 having an appropriate interval coated with a fluorescent paint and an alarm scale 11 and height adjusting bolts 12 and 12 'for adjusting the horizontal position are attached to the upper surface and the outer bottom surface of the body 2, .

The slope determining device 1 of the present invention is attached to various points on the upper part of an existing building, a bridge or a new building, and when it is sealed by adjusting the zero point, the slope determining device 1 can be used as a basis document for discriminating inclination due to natural settlement and artificial settlement The height of the height adjustment bolts 12 and 12 'of the bottom of the container 2 may be adjusted so that the height of the floor of the building or the bridge is not precisely adjusted. The indicating body 5 hanging from the thread 4 is fixed to the container 2 when the indicator 5 hanging on the thread is fixedly installed and fixed in a state of zero point adjustment of the indication scale 10 so as to stand perpendicular to the horizontal plane. The indicating body 5 is always positioned at the zero point of the indication scale 10 in a state where the building or the bridge is not inclined because the antifreeze 3 filled in the antifreeze 3 is always upright with respect to the horizontal plane. It is to be so that the indicating device (5) by an angle inclined when the building or bridge at an angle to determine the state inclined by scale out so out the zero point of the scale display 10.

FIG. 3 is a calculation diagram for determining the degree of inclination with respect to the horizontal plane when the floor of the building is an inclined plane. The inclination can be obtained by the following equation.

[Formula] tilt .

d: Length of the indicator.

r: Length of yarn.

L: Trajectory of the line drawn by the indicator.

θ: The angle between the horizontal plane and the slope.

The inclination can be measured by the above formula and the alarm scale 11 can be displayed on the outside of the display scale 10 to visually confirm the degree of danger so that a safety accident can be prevented in advance.

The antifreeze 3 filled in the container 2 is a liquid which does not freeze in the winter season and should have a certain viscosity. Such a liquid is expanded and contracted according to the temperature change, so that the pressure regulating device 9 Is provided on the outer bottom surface of the container 2 to cope with the change.

That is, the pressure regulating device 9 provided to communicate with the inside of the container 2 is provided so that the blocking plate 6 is installed to block the flow of the antifreeze liquid, and the blocking plate 6 is regulated as the elastic regulating bolt 8 When the antifreeze 3 is inflated in the summer when the temperature is high, the blocking plate 6 is pushed outward while pressing the spring 7 by the inflation pressure. It will be possible.

As described above, the present invention can be applied to a building or a bridge to determine whether a manager or a passenger can easily lean, thereby effectively coping with a collapse of buildings and bridges, and can greatly reduce accidents caused by human resources. In particular, So that it can be practically used at an inexpensive price.
