To provide.

In the case of large building structures such as bridges or water tanks, concrete structures are not integrally placed, but are composed of several structures in consideration of expansion or contraction of concrete, and are constructed with constant intervals between the structures.

In this case, the gap is not fixed but is a fluid gap (aka, flow gap), which changes in size due to temperature change, external force, abnormal behavior of the structure, and the like.

In order to measure the gap, a device such as a camera or a lens is used as in Korean Patent Registration No. 10-1765806, but such a device has a problem in that the configuration is complicated and expensive.

It is necessary to measure the size of these gaps periodically, in which case rulers are used to measure these gaps. However, in the case of such a ruler, the measurement should be made on the same plane, but there is a problem that it is difficult to measure when the spaced structures are not coplanar (when either structure protrudes).

An object of the present invention is to provide a clearance measurement device for safety diagnosis of a structure that can easily measure a change in clearance distance in a structure with clearance between a plurality of structural elements.

According to the present invention, it is possible to track the change in the spacing between structures by additionally measuring only the spacing between protrusions of the linking device, without having to resort to traditional measuring methods such as graduated calibrator.

On the other hand, even if the bridge is behaved by vehicle load, it can be measured without being affected. That is, in the case of a bridge, the place where the clearance is located rotates when the end of the structure is subjected to a vehicle load. Since the present invention provides a rotatable link structure, even when the bridge structure (upper structure) is rotated, the position of the link portion is the same. Can be used to measure long-term flow fluctuations.

In addition, even if there is a step between the two structures, even if the height or the degree of protrusion is different, it is possible to easily measure the change in spacing of the gap.

3 illustrates a method of using the clearance gap measuring apparatus 1 for safety diagnosis of a structure having such a structure.

FIG. 3 (a) shows a state before the flow between the first structure and the second structure changes, and FIG. 3 (b) shows a state where the flow between the first structure and the second structure is narrowed and changed as indicated by arrows. .

As shown in FIG. 3 (a), when the linkage device 1 for measuring the clearance between the building structures according to the present invention is disposed between two structures B1 and B2, the arrangement state of the linkage device 1 is It is bent (folded) like a 'V'.

Here, the first and second base plates 110 and 120 are attached to the first and second structures B1 and B2 by bolts, epoxy bonds, or the like.

In the state where the structure is initially placed, the first crude oil clearance distance (for example, 15 cm) is measured, the linkage device 1 is disposed therebetween, and then the first protrusion 314 and the first protrusion 314 of the linkage device 1 are placed. The distance between the two protrusions 324 is measured.

Then, as time passes, the clearance between the two structures B1 and B2 may change. As described above, the clearance distance may change due to aging, expansion or contraction of the structure, and thus the arrangement state of the linkage device 1 changes.

In FIG. 3 (b), the structures B1 and B2 are moved in the direction of the arrow, and the distance between the structures is closer to each other. In this case, the first link units 210 and 310 constituting the link device 1 are illustrated. And as the angles formed by the second link portions 220 and 320 change (narrower), the distance between the first protrusion 314 and the second protrusion 324 also becomes closer.

That is, the first protrusion 314 may move in the direction of the second protrusion 324 by T1 from the previous position, and the second protrusion 324 may move in the direction of the first protrusion 314 by T2.

In this case, by measuring the distance between the new first protrusion 314 and the second protrusion 324, by calculating the changed clearance distance between the first structure (B1) and the second structure (B2) in consideration of the change of the gap. The current clearance distance can be calculated.

According to the present invention, when the upper surfaces of the first structure B1 and the second structure B2 are not the same plane or the side surfaces of the first structure B1 and the second structure B2 are not the same plane, the measurement is performed. This is useful when measuring with a ruler is difficult.

That is, when the upper surface or the side surface of the first structure B1 enters or protrudes from the upper surface or the side surface of the second structure B2, it is difficult to measure the measurement ruler so that such a link device 1 and A separate conventional commercial measuring device (eg, digital vernier caliper) can be used to measure the change in clearance distance.

On the other hand, when either one of the first structure (B1) or the second structure (B2) is subjected to the lateral load or the downward pressure, it can rotate slightly, accordingly, the first base portion 110 or the second base portion 120 ) May be inclined rather than horizontal or vertical, but even in this case, the first and second base parts 110 and 120 and the first and second link parts 210, 310, 220, and 320 may be inclined. ) Is rotated, the arrangement state of the first, second link unit (210, 310, 220, 320) can remain unchanged.

4 is not installed on the surface facing each other as shown in Figure 1 for the safety diagnosis of the structure according to the present invention, but on different planes (for example, one side vertical, the other horizontal) The case where it is arrange | positioned is shown.

For example, if there is a structure that is difficult to attach the first base portion 11- to the vertical surface of the first structure (B1), or the surface is too irregular, the lower surface (horizontal surface) of the structure should be utilized, Figure 4 and As described above, the first base part 110 connected to the first link parts 210 and 310 is attached to the bottom surface (horizontal plane) of the first structure B1 and the second link part 220 and 320 is connected to the second base part 110. After attaching the base unit 120 to the vertical surface of the second structure B2, the change in the distance between the first structure B1 and the second structure B2 may be tracked.

In the state where the structure is initially placed, the first crude oil clearance distance (for example, 15 cm) is measured, the linkage device 1 is disposed therebetween, and then the first protrusion 314 and the first protrusion 314 of the linkage device 1 are placed. The distance between the two protrusions 324 is measured.

Here, the raw clearance distance may be a distance from a lower edge of the first structure B1 to a side wall (vertical wall) of the second structure B2.

Then, as time passes, the clearance between the two structures B1 and B2 may change. As described above, the clearance distance may change due to aging, expansion or contraction of the structure, and thus the arrangement state of the linkage device 1 changes.

In this case, as the angles formed by the first link portions 210 and 310 and the second link portions 220 and 320 constituting the link device 1 change (narrow down), the first protrusion 314 and the second The distance between the protrusions 324 is also close.

In this case, by measuring the distance between the new first protrusion 314 and the second protrusion 314, by calculating the changed clearance distance between the first structure (B1) and the second structure (B2) in consideration of the change of the gap. The current clearance distance can be calculated.

FIG. 5 shows a state in which the clearance gap measuring apparatus 1 for safety diagnosis of the structure according to the present invention is attached to two structures B1 and B2 having different heights or protrusion levels, and a change state thereof.

As shown in Fig. 5A, the first base portion 110 is attached to the surface of the relatively high (more protruding) first structure B1, and the second base portion 120 is relatively It is attached to the face of the lower (less protruding) second structure B2.

Here, the first direction (eg, the horizontal direction) interval of the first protrusion 314 and the second protrusion 324 is G1 and is orthogonal to the first direction between the first protrusion 314 and the second protrusion 324. The second direction (eg vertical direction) spacing is zero.

In the state of initially placing the structure in the state of FIG. 5 (a), the difference between the clearance distance in the first direction and the height (or distance) in the second direction is measured, and the linkage device 1 is placed thereon. The distance between the first protrusion 314 and the second protrusion 324 in (1) is measured.

Thereafter, as time elapses, as shown in FIG. 5 (b), the distance between the clearances in the first direction and the height (or distance) in the second direction may change between the two structures. As described above, the clearance distance may change due to aging, expansion or contraction of the structure, and thus the arrangement state of the clearance clearance measuring apparatus 1 for safety diagnosis of the structure changes.

In this case, as the angles formed by the first link portions 210 and 310 and the second link portions 220 and 320 constituting the clearance diagnosis device 1 for safety diagnosis of the structure are changed (narrowing), the first protrusion portion The distance between 314 and the second protrusion 324 also changes.

That is, a change in the degree of protrusion and the spacing between the first structure B1 and the second structure B2 occurs due to the relative movement between the structures, which is reflected in the link device 1 as it is.

In such a case, the distance between the first protrusion 314 and the second protrusion 324 in the first direction (eg, the horizontal direction) after the change is changed to G2, and the gap between the first protrusion 314 and the second protrusion 324 is changed. The second direction (eg vertical direction) spacing changed to G3.

In this case, the first structures 314 and the second structures are measured in consideration of the change of the gaps by measuring the gaps (first gap, second gap) between the new first projection 314 and the second projection 324. By calculating the changed clearance distance or relative protrusion state between the structures 324, the current clearance distance and relative protrusion state can be calculated.

Figure 6 is another embodiment of the clearance gap measuring device 1 for the safety diagnosis of the structure according to the present invention, the structure is more simply implemented.

As shown in FIG. 6, in the present embodiment, the first and second link housings 210 and 220 shown in FIG. 1 are omitted, and the first and second link bars 310 and 320 are respectively the first base part 110. ) And the second base portion 120.

That is, the first link bar 310 is rotatably connected to the first connecting plate 112 provided on the first base part 110, and the second connecting plate provided on the second base part 120. The second link bar 320 is rotatably connected to the 122, and the first link bar 310 and the second link bar 320 are also rotatably connected to each other.

The first and second protrusions 314 and 324 are provided at the first and second link bars 310 and 320, respectively, and are spaced apart from each other, and as shown in FIG. When the angles of the first and second protrusions 314 and 324 change when the 310 and 320 are folded, the distance difference between the first and second protrusions 314 and 324 also changes, and the changed value of the distance between the original structures may be calculated. The calculation method is the same as that described in FIGS.

7 illustrates an embodiment in which an auxiliary block 400 is included.

A separate auxiliary block 400 is disposed on the rear surface of the base plate constituting the first base part 110 or the second base part 120. As shown in FIG. 7 (b), the auxiliary block 400 is disposed to compensate for the difference between the two structures when the step difference is too severe.

Therefore, when the height difference or the protrusion degree difference between the two structures B1 and B2 is h1, the surface of the structure of the relatively low (small protrusion) structure of the auxiliary block 400 having the height of h1 corresponding to the difference is h1. And the first base portion 110 or the second base portion 120 are fixed to the auxiliary block 400 so that the linkage device according to the present invention is provided to the first structure B1 and the second structure B2. Can be installed.

Here, the calculation of the gap between the first and second protrusions 314 and 324 according to the gap between the structures and the change of the gap between the structures reflecting the same are the same as described above, and thus description thereof will be omitted for avoiding redundant description.

As described above, the present invention has been described with reference to the embodiments shown in the drawings, but it is only for the purpose of describing the present invention, and those skilled in the art to which the present invention pertains various modifications or equivalents from the detailed description of the invention. It will be appreciated that one embodiment is possible.

Therefore, the true scope of the present invention should be determined by the technical spirit of the claims.
