Therefore, the embodiments described in this specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, It is to be understood that equivalents and modifications are possible.

As shown in FIG. 1A, in order to protect the outer circumferential surface of the water structure 10 such as a column from waves and the like, a sheet pile 23 having a length of about 1 to 2 m above the surface of the column based on the water surface ( 20) is installed.

The sheet pile assembly 20 generally includes a groove part by zigzag through a connecting ring 23a formed at each end of the plurality of U-shaped unit sheet piles 23 as shown in FIGS. 1B to 1C. 22) and the protrusions 21 are formed in a cylindrical shape. However, as illustrated in FIG. 1, the shape of the sheet pile assembly 20 may be variously formed in a straight line or the like according to the shape of the water phase structure 10. Therefore, the shape of the sheet pile assembly 20 to which the present invention is applied is not limited to the cylindrical shape.

The present invention relates to a painting work table 100 for painting the sheet pile 23 installed in such a water structure (10).

As shown in FIGS. 2 to 4, the sheet pile 23 painting work table 100 of the water structure 10 according to the exemplary embodiment of the present invention may be formed on two outer peripheral surfaces of the protrusions 21 of the sheet pile assembly 20. Each of the coupling member 111 and the coupling plate 112 connecting the two coupling plate 111 and the coupling member 110 and each of the lower portion of the lower member 110 is connected to the groove portion 22 At least one water film formed in a corresponding shape is characterized in that it comprises a support member (120). Therefore, the coating work table 100 of the present invention is not applied only to the structure of the sheet pile 23 shown in FIGS. 1B to 1C, and if only the groove portion 22 and the protrusion 21 are formed, the sheet pile of any structure ( 23 can also be applied by changing the shape.

The order member 110 is to form a kind of order wall, it is preferable to have a length extending about 1 to 2m to the top and bottom relative to the water surface in order to prevent water from penetrating into the interior of the painting work platform by the wave. .

The order member 110 has a coupling plate 111 formed on the left and right sides of the connection plate 112, respectively, and the coupling plate 111 is formed on the outer circumferential surface of the protrusion 21 of the sheet pile assembly 20. Combined. Therefore, the coupling plate 111 and the protrusion 21 of the sheet pile assembly 20 are coupled in a face-to-face, so that seawater can be inherently blocked.

On the other hand, as shown in Fig. 2 or 4, if there is a protrusion 21 between the two left and right coupling plate 111, the auxiliary coupling is formed to extend to the bottom of the connecting plate to be coupled to the outer peripheral surface of the protrusion 21 The plate 111a may be further provided. As shown in FIG. 2 and FIG. 4, when the auxiliary coupling plate 111a is further provided, the auxiliary coupling plate 111a is coupled to the outer peripheral surfaces of the left and right sides by the coupling plate 111. By the protrusion 21 can be tightly coupled to the outer peripheral surface therebetween because it is coupled more firmly.

As the coupling method of the coupling plate 111 or the auxiliary coupling plate 111a and the protrusion 21, a coupling method using a plurality of bolts and nuts or other general fastening methods may be used, but in the case of the present invention, the coupling plate 111 or the auxiliary coupling plate (111a) and the protrusion 21 is characterized in that to be coupled by a magnet.

That is, generally, the sheet pile 23 is formed of a steel material, and may be formed of a material that can be coupled to a magnet even if the steel is not a steel material, and the protrusion 21 of the coupling plate 111 and the sheet pile assembly 20. ) Is coupled to face-to-face using the magnet 130 as shown in FIG.

Magnet 130 used in the present invention is not limited to the kind, but if necessary using a magnet 130, such as a lifting magnet (Lifting magnet, so-called 'leafma') that can be turned ON (OFF) When the 130 is turned on to be coupled to the sheet pile assembly and detached to change the position of the painting work bench, it is preferable to turn off the magnet 130 to easily change the position of the pile pile assembly 20. As shown in FIG. 2, the magnet 130 may be disposed at a boundary between the coupling plate 111 and the outer circumferential surface of the protrusion 21 to transmit the force of the magnet to both.

However, the magnetic coupling in the present invention is not limited to the configuration using the reefma as described above. That is, the material itself of the coupling plate 111 or the auxiliary coupling plate 111a may be formed of a magnetic material so as to be coupled to the outer circumferential surface of the protrusion 21 of the sheet pile as the binding plate 111 or the auxiliary coupling. Various methods that can be coupled with a magnet are possible, such as a method of disposing a magnet plate between the plate 111a and the protrusion 21 to be coupled to each other.

When the magnet is coupled to the magnet, the coupling force of the magnet acts on almost all surfaces of the coupling plate 111, so that the penetration of seawater can be more reliably blocked. And since the coating work table 100, such as the present invention is installed on the basis of the water, there is a problem that is more difficult and dangerous work than in a normal environment. Therefore, a large amount of time and manpower is required to couple the protrusions 21 of the coupling plate 111 and the sheet pile assembly 20 in the conventional manner such as bolts, nuts, and welding. Since the fastening work must be performed by welding or the like, a difficult problem occurs. However, when combined with the present invention and the magnet, the coupling and separation operation itself is very simple, even after the magnet coupling, even if the coupling bolts, nuts and welding additionally coupled plate 111 itself is coupled to the magnet and fixed Since the bolt nut and the welding in the state it is in effect can be installed more easily.

In addition, a separate waterproof member (not shown) may be disposed between the coupling plate 111 and the protrusion 21 to further improve order performance. Here, the waterproof member is preferably made of soft synthetic resin or rubber material.

The support member 120 is formed in a plate shape corresponding to the groove portion 22 of the sheet pile assembly 20 as a water blocking member under the order member 110. When the supporting member 120 is coupled to the sheet pile assembly 20 together with the order member 110 as shown in FIG. 4, the water is prevented from penetrating from the side of the painting work table 100 and the lower surface of the paint work table 100. It is possible to carry out painting work. Therefore, the painting work and other maintenance work can be facilitated, and the painting quality can be improved, and the corrosion of the sheet pile 23 can be effectively prevented.

Since the support member 120 is formed to correspond to the groove portion 22 of the sheet pile assembly 20, the shape of the support member 120 varies according to the shape of the groove portion 22 of the sheet pile assembly 20. Therefore, it is not limited to the shape of the support member 120 shown in FIG.

Meanwhile, in the case of the present invention, as shown in FIG. 4, the connecting plate 112 of the order member 110 is formed to extend backwardly between the two coupling plates 111 in a letter B to form a step 112a. And, the length of the connecting plate 112 is formed to include two or more grooves 22 of the sheet pile assembly 20, the support member 120 in the order member 110 therein It is provided with the same number as the number of the groove portion 22 included, and is configured to be coupled to each groove portion 22.

The reason for this formation is that at least one protrusion between the grooves 22 must be formed such that the left and right lengths of the connecting plate 112 include at least two grooves 22 as shown in FIG. 3 or 4. 21 may be included, and the connecting plate 112 may be formed in a N-shape so that the stepped portion 112a is present to form a space H between the connecting plate 112 and the protrusion 22 to enter the worker. This is because the painting can be performed on the outer circumferential surface of the protrusion 21. That is, when the connecting plate 112 is not formed in a b-shape and is formed in a straight line so that the step 112a does not exist, the outer circumferential surface of the groove part 22 may be painted, but the painting work is not possible on the outer circumferential surface of the protrusion 21. Since there is a problem of deterioration is to form a step (112a) in the N-shape in order to secure space for painting the protrusions (21).

Accordingly, as shown in FIG. 3, the connecting plate 112 may be formed to a length that may include two grooves 22 and one protrusion 21, and further, three or more grooves 22. It may be formed to a length that can be included.

In the case of the connecting plate 112, the shape of the connecting plate 112 may be variously formed according to the shape of the outer circumferential surface of the receiving structure 10. In the case of the present invention, as shown in Figure 2, when installed in the water structure 10, such as a cylinder, it is preferable that the connecting plate 112 is formed to be somewhat curved along the arc. Accordingly, it is a matter of course that the rear surface of the support member 120 placed inside the stepped portion 112a may be changed.

Meanwhile, as illustrated in FIG. 2, one or more angles 113 may be additionally disposed horizontally on the outer circumferential surface of the connecting plate 112. The horizontal angle 113 supports the connecting plate 112 to prevent the connecting plate from bending due to water pressure.

In addition, when the connecting plate 112 is manufactured in a N-shape as described above to form a stepped step, the rear end of the supporting member 120 may be placed on the stepped part 112a to be coupled to the order member 110. . Therefore, when connecting the order member 110 and the support member 120, the upper surface of the step (112a) and the lower surface of the support member 120 is coupled in close contact with the face-to-face support member 120 and the order member 110 There is an advantage that it is difficult to penetrate the seawater between the) so that it can be stably.

On the other hand, a separate waterproof member may be disposed between the upper surface of the stepped portion 112a and the lower surface of the support member 120 to further improve order performance. Here, the waterproof member is preferably made of soft synthetic resin or rubber material.

However, depending on the situation, the supporting member 120 may be coupled to the end portion of the step 112a by welding or the like without being placed on the step 112a of the order member 110.

In addition, the lower portion of the support member 120 is preferably extended to a shape corresponding to the groove portion 21 to be made of a bending portion 121 in close contact with the groove portion 22. As shown in FIG. 5, the sheet is formed by extending the end of the remaining portion except for the portion coupled to the stepped portion 112a of the connecting plate 112 to form a bending portion 121 in the supporting member 120. It is in close contact with the groove portion 22 of the pile 23 face to face to improve the degree of performance. As a result, even if several workers climb on the support member 120, it is possible to stably support the weight.

On the other hand, the inner peripheral surface of the bending portion 121 is further included a separate waterproof member is coupled to the groove portion 22 of the sheet pile can improve the order performance. Here, the waterproof member is preferably made of soft synthetic resin or rubber material.

The order member 110 and the support member 120 configured as described above may be formed separately from each other as shown in FIG. 4, but in another embodiment, the order member 110 and the support member 120 may be separated from the first. It can also be formed integrally with a plate. As a preferred embodiment, as shown in FIG. 2, both the order member 110 and the support member 120 including the coupling plate 111, the auxiliary coupling plate 111a, and the connection plate 112 on which the step 112a is formed, are provided. It is formed integrally. In this case, since there is no gap between the order member 110 and the support member 120, there is no fear that water may penetrate, and the installation work is simplified because the support member does not need to be combined by welding. do.

However, since it is not easy to change to fit the shape of the groove portion 22 of the various sheet pile assembly 20 is a disadvantage that the applicability is poor. On the contrary, when the order member 110 and the support member 120 are separated and configured as described above, the shape of the support member 120 may be reduced, but the shape of the support member 120 may be maintained. Since it can be manufactured according to the shape of the groove portion 22 of 20) there is an advantage that can be easily changed and applied at a low cost.

Referring to performing the painting operation by the dry painting work table 100 of the water pile structure sheet sheet 23 according to an embodiment of the present invention, first prepare the order member 110 to position higher than the water surface The coupling plate 111 or the auxiliary coupling plate 111a is fastened to the outer circumferential surface of the protrusion 21 of the sheet pile assembly 20 by magnet coupling or the like. Then, the supporting members 120 made to fit the grooves 22 of the sheet pile assembly 20 are placed in the stepped portion 112a of the order member 110 and joined by welding to prevent water leakage. In this state, since water has penetrated into the painting worktable 100, the water inside is removed by using a pump or the like. Then, all of the water in the painting worktable 100 is removed to perform a painting work on the sheet pile assembly 20 of the water structure 10 in a dried state. Therefore, according to the dry painting work table 100 of the water pile structure 10, the sheet pile 23 according to the present invention can be installed very easily, and since the painting work is performed reliably in a dry state, corrosion of the sheet pile 23 is prevented. It can effectively block.

As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto and is intended by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.
