The spherical hinge located at one end of the spherical hinge has a coupling groove to which the spherical hinge can be rotatably engaged and is connected to the structure via a fixing band fixed to the structure.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view of a measuring apparatus according to the present invention, will be described with reference to this.

The measuring apparatus according to the present invention includes a platform 120 connected to the structure 10 embedded in the basement, the platform 120 is inserted into the anchor 110 is embedded in the ground, and the anchor 110 via a wire ) And an output device 160 for energizing.

The anchor 110 is embedded into the basement bed 30 in the base is firmly fixed, and becomes a reference position for observation of ground subsidence. The anchor 110 for this purpose is a long bar-shaped pile tapered lower end, the hollow 111 is formed inside.

The hollow 111 is where the components for checking the settlement of the soft ground 20, the structure 10 is embedded is inserted, Figure 2 (sectional view showing the installation of the measuring device according to the invention) It will be described in more detail with reference to.

The hollow 111 is formed along the longitudinal direction of the anchor 110, the hollow 111 is a coil 184, pistons 181, 182, carbohydrate 170 and the platform 120 in sequence It is inserted and laminated.

As described above, the platform 120 is connected to the structure 10, the platform 120 is also raised and lowered in accordance with the elevation of the structure (10). That is, by detecting the movement of the structure 10 to recognize whether the ground subsidence that can cause damage to the structure (10).

The platform 120 is connected to the structure 10 via the linker 130. At this time, both ends of the linker 130 is composed of spherical hinges (131, 132) having a predetermined outer diameter, so as to maintain a rotatable connection state between the platform 120 and the structure (10). .

In more detail, the ground subsidence is not a two-dimensional movement that occurs only in the vertical direction, but a three-dimensional movement that occurs in all directions such as up, down, left, and right. Therefore, when ground subsidence occurs in the up-down direction, which is parallel with the anchoring direction of the anchor 110, there is no difficulty between the anchor 110, the platform 120, and the linker 130 that are firmly fixed to the base arm 30. As the mesh is engaged, stable driving is possible.

However, when ground subsidence occurs somewhat twisted, if both ends of the linker 130 is firmly connected to each of the structure 10 and the anchor 110, the change in the fixed position of the anchor 110 fixed to the base arm 30 May occur, and both ends of the linker 130 may be separated from the structure 10 and the platform 120, and thus may lose the function of the measuring apparatus according to the present invention.

Accordingly, the linker 130 has spherical hinges 131 and 132 at both ends thereof, so that the flexible linkage between the anchor 110 that is firmly fixed and the structure 10 that is affected by ground subsidence occurring in various directions. To make it possible. To this end, in the structure 10 is engaged with the spherical hinge 132 disposed on one end of the linker 130 is connected to the spherical hinge 132 is rotatably coupled to the coupling groove 151, On the platform 120 to which the spherical hinge 131 disposed at the other end of the linker 130 is engaged, a rotary groove 121 is disposed to be rotatably coupled to the spherical hinge 131.

Withdrawal number '140' is a fixing member for coupling between the spherical hinges (131, 132) and the connection groove 151 and the rotary groove 121, the spherical connectors (131, 132) is the connection groove ( 151 and the rotating groove 121 is engaged with the cover to hold it so as not to be separated, for this purpose is provided with a through hole 141 to allow the linker 130 to penetrate. By the way, in Fig. 1 and 2 is shown to be applied only between the rotary groove 121 and the spherical hinge 131 of the platform 120, the measurement device according to the invention is not limited to the configuration shown, Of course, various modifications can be made without departing from the scope of the claims.

Unexplained number '133' is a 'connector', so that the linker 130 can be separated two or more. When the connector 133 connects the spherical hinges 131 and 132 with the connection groove 151 and the rotation groove 121 by using the same member as the fixing member 140, the through hole 141. The outer diameter of the larger spherical hinge (131, 132) is to be fitted.

Briefly describing the process, after engaging the spherical hinge 131 of the linker 130 in which the middle is separated on the rotary groove 121, the through hole 141 of the fixing member 140 is spherical hinge It penetrates into the separated interruption 131 rather than 131 and pushes the spherical hinge 131 toward the spherical hinge 131 so that the spherical hinge 131 can be trapped in the rotary groove 121.

On the other hand, the connection groove 151 is positioned in the fixing band 150 is fixed while wrapping the outer peripheral surface of the structure 10, so that it can be fixedly fixed to the structure (10).

The platform 120 is inserted into the hollow 111 of the anchor 110, and moves along the hollow 111 by the operation of the linker 130. At this time, the platform 120 is supported by the carbaceous body 170, the carburetor 170 is interlocked with the first piston (181). Meanwhile, the first piston 181 is interlocked with the second piston 182 with the liquid medium 190 therebetween, and the second piston 182 includes a magnetic body 183.

That is, when the platform 120 moves, the moving force is transmitted to the carcass 170, and when the force exceeding the elastic limit of the carcass 170 is applied, the carcass force of the carcass 170 is increased. It is applied to the first piston 181. In addition, the first piston 181 received the elastic force to transmit the elastic force to the liquid medium (190) to be delivered to the second piston 182, and eventually the second piston 182 is moved while the magnetic material ( 183) will be moved together.

At this time, the carcass 170 absorbs the minute movement of the platform 120 so that the piston (181, 182) is not subjected to the force. Indeed, although the structure 10 is buried underground, it can move even minutely to the vibration generated from the ground rather than ground erosion. In addition, since the structure 10 may move even in the case of erosion in which the risk level is not large, it is necessary to prevent the structure 10 from reacting to the negligible movement of the structure 10.

The pistons 181 and 182 that interlock with the carcass 170 are disposed with the liquid medium 190 closely injected between the first piston 181 and the second piston 182. The liquid medium 190 is a force transmission medium for pressure transmission, and a fat having a mucus property is used, but is not limited thereto, and water may be utilized.

Subsequently, the second piston 182 engages its outer circumferential surface with the inner circumferential surface of the hollow 111 so that the second piston 182 can hold its current position by friction. That is, since the second piston 182 does not have any support means below, the frictional force between the outer circumferential surface of the second piston 182 and the inner circumferential surface of the hollow 111 determines the current position of the second piston 182. It is the only means of holding. Meanwhile, the friction force between the second piston 182 and the hollow 111 should be able to support the load of the liquid medium 190. This is because there is no supporting means below the second piston 182 as described above, and thus the frictional force must support the liquid medium 190 to move downward by gravity.

This is to allow the measuring device according to the present invention to react sensitively even to the small movement of the structure 10 in the range over the elastic force of the carburizing body 170. That is, when a small pressure of the first piston 181 is transmitted to the liquid medium 190, the liquid medium 190 applies pressure to the second piston 182 together with its own weight, and the second pressure. The piston 182 is easily operated by the pressure exceeding the frictional force between the hollow 111 and the second piston 182, but can be stopped immediately when the pressure excluding the self-weight of the liquid medium 190 disappears. will be.

On the other hand, the first piston 181 is fixed to the platform 120 via the carcass 170. That is, if there is no movement of the platform 120, the first piston 181 also can not be pushed downward by the load, but also to increase the pressure transfer efficiency while preventing leakage of the liquid medium (190) Since the two pistons 182 are closely interlocked with the friction force corresponding to the friction force formed on the outer circumferential surface of the two pistons 182, the downward movement of the liquid medium 190 is prevented by internal pressure.

Therefore, the structure in the hollow 111 according to the present invention is the hollow 111 formed along the longitudinal direction of the anchor 110, the second piston 182, the liquid medium 190, carbohydrate 170 And although the platform 120 is arranged linearly, the second piston 182 is sensitively moved by the movement of the platform 120 without being pushed down by its own weight.

Subsequently, the second piston 182 includes a magnetic body 183, and the magnetic body 183 is movably inserted along the inner side of the coil 184.

Electrodynamically, when a magnetic force in the coil 184 occurs, an electromagnetic induction current is generated along the coil 184, the measuring device according to the present invention by applying this natural law to the minute movement of the structure 10 Can be detected.

On the other hand, the coil 184 is energized with the output device 160 that can be installed on the ground via the wire 165.

The output device 160 detects the electric shock induced current generated by the movement of the structure 10 to check the degree of movement, and outputs so that the administrator can recognize.

The output device 160 may include a current detector 163, a control mechanism 164 that recognizes and processes the detection of the current detector 163, and an output unit operated by a command of the control mechanism 164. 161 and a speaker 162.

The current detector 163 has the same structure as a general ammeter and senses the magnitude of the induced current generated in the coil 184. The ammeter is already well known, and a description of the current sensing device 163 according to the present invention having the same structure will be omitted.

Since the current detector 163 is the same as a general ammeter, it is possible to measure not only the occurrence of the induced current but also its intensity. On the other hand, the structure of the anchor 110 described above is such that when the movement of the structure 10 is large, the movement range of the second piston 182 is also increased, so that the magnetic body 183 is large in the coil 184 Will move.

Electrodynamically, when the movement of the magnetic body 183 in the coil 184 is large, the generated induced current is also large, the current sensing sphere 163 will detect the generation of a large current.

The detection result of the current sensing opening 163 is transmitted to the control mechanism 164. The control mechanism 164 checks the intensity of the induced current generated so that it can be visually or spoken through the output unit 161 and the speaker 162 when it exceeds a predetermined value.

On the other hand, in the measuring device according to the present invention by placing a lamp of various colors on the output unit 161, the control mechanism 164 the number of times the movement of a predetermined range or more with respect to the structure (10) the current sensing sphere 163 The lamps of different colors may emit light according to the number of times accumulated through the detection.

That is, if the intensity of the induced induction current does not occur, the blue lamp always emits light, and if the predetermined induction current intensity occurs more than once or ten times, the yellow lamp emits light. When more than one occurrence of the red lamp is to emit light.

This can be controlled through the control mechanism 164, and the control mechanism 164 can be easily realized by those skilled in the art as a CPU chip set with a program containing the above-described flow. Therefore, the circuit description of the control mechanism 164 will be omitted.

According to the present invention as described above, the degree of settlement of the ground that can cause the damage of the structure can be monitored sensitively and efficiently without excessive cost input, the occurrence of accidents by reinforcing the structure before the full ground settlement It can be prevented, and there is an effect that can prevent the expansion of large accidents.
