FIG. 3B is a perspective view illustrating a closed end of the corrugated closure index plate according to an embodiment of the present invention. FIG. 3C is a perspective view showing a configuration of a corrugated closure index plate used in a pontoon block, FIG. 3C is a perspective view showing a configuration when a corrugated closure index plate used in a pontoon block according to an embodiment of the present invention is joined to a corner portion of a unit pontoon FIG.

3A, since both ends of the corrugated closure member 400 can be fitted and fused, a separate edge coupling member is provided at the corner of the unit pontoon 100, and a waterproof plate is cut and installed So that it is possible to prevent external water from flowing into the unit pontoons 200 at the portion where the waterproof plate is broken. That is, the pleated hollow 402a is closed and can be completely cut off from the outside.

Referring to FIG. 3B, the corrugated closing plate 400 is formed of a horizontal plate member. The center of the corrugated closing plate 400 can be stretched and contracted in a direction perpendicular to the center line, The first plate portion 401 and the second plate portion 403 are integrally formed on both sides of the multi-directional wrinkle portion 402 and the multi-directional wrinkle portion 402, And is extruded into a synthetic resin material.

The multi-directional wrinkle portion 402 includes a corrugated hollow 402a and a corrugated frame 402b that surrounds the corrugated hollow 402a and can be directionally expanded or contracted according to a predetermined lateral pressure or tensile force.

Particularly, since the pleated rim 402b surrounds the pleated hollow 402a and forms a multi-layer structure, when a crack occurs in the joining surface of the unit pontoon 100, it is easy to maintain elongation and durability Do.

The pleated rim 302b may be provided with a pleated hollow 402a and an air hole 402c communicating with the outer space to facilitate the change of the cross section of the hollow portion due to elongation and contraction.

The first and second plate portions 401 and 403 are connected to each other in the height direction of the multi-directional wrinkle portion 402, and the thickness of the first and second plate portions 401 and 403, Since the thickness of the rim 402b can be equalized, the durability of the corrugated closing plate 400 can be increased.

The corrugated rim 302b is formed in a substantially rectangular shape having a vertical width larger than the lateral width of the corrugated rim 302b, preferably in a direction perpendicular to the first and second plate tops 401 and 403 And having a rectangular shape having long sides is preferable because it can be stretched more in the transverse direction when cracks are generated at the joint surface between the unit pontoons 100. [

The length of the long side of the corrugated rim 402b is longer than the length of the concave portions 120 and 130 of the unit pontoon 100a in which the multi-directional wrinkle 402 is installed, It is preferable that the indentation performance can be continuously maintained by closing the concave portions 120 and 130 even if the corrugated portion 402 is recognized by the tensile force due to the cracks between the unit pontoons 100 (see FIG. 4A).

The long sides of the corrugated rim 302b are symmetrical with respect to the horizontal direction of the first and second plate portions 401 and 403 and the vertical direction of the first and second plate portions 401 and 403, Shaped hollow 402a is suitable for maintaining the exponential state in accordance with the cracks between the bonding surfaces of the unit fiberboard 100, and it is preferable that the expandable grooves 120, It is most preferable to consider the durability and the degree of tensile strength of the multi-directional wrinkles 402.

Even when the long side of the corrugated rim 402b is bent twice or more from the middle to the upper side to form a large number of corrugations, the corrugated frame 402b has durability sufficient to support the load at the time of occurrence of cracks between the unit pontoons 100, It can be given to the closed index plate. Further, the multi-directional wrinkle portion 402 can maintain a closed structure in the stretchable and contractible grooves 120 and 130.

The surface or the rear surface of the first plate portion 401 and the second plate portion 403 is perpendicular to the first plate portion 401 and the second plate portion 403 and the length of the corrugated closing plate 400 At least one protrusion 404 may be formed.

The protrusion 404 may be formed integrally with the corrugated closing plate 400. When the protrusion 404 is formed to have a high height, the protrusion 404 may be formed in the grout material 1000, The first and second plate portions 401 and 403 can be firmly integrated with the grout material 130 when the first and second plate portions 401 and 403 are embedded, It is possible to maximize the frictional resistance of the flow velocity by minimizing the leakage of water into the unit pontoons 200 by increasing the moving distance of the water even in the situation where the external water penetrates into the unit pontoons 100 due to the cracks.

Preferably, the protrusions 404 are formed in two to four rows at regular intervals along the longitudinal direction of the corrugated coupling plate 400.

The first plate upper portion 401 and the second plate upper portion 403 are formed on the upper surfaces of the upper and lower upper plate portions 401 and 403 along both edges of the widthwise ends of the corrugated closing plate 400 And the spacer 405 may protrude perpendicularly to the first and second plate portions 401 and 403. The spacer 405 may have a plurality of spacers 405 formed on the back surface thereof.

When the first and second plate top portions 401 and 403 are installed in the fixing groove 110b or the spot filling recessed portion 120 of the unit pontoon 100, When the grout material 130 is injected so that the two plate tops 401 and 403 are not in close contact with the surfaces of the fixing grooves 110b and the placement grooves 120, 110b or the cast-in-place recess 120, as well as to a large area with respect to the ends of the stationary groove 110b or the cast-in-place recess 120, So that the coupling strength between the second plate portions 401 and 403 and the grout material 1000 is increased and the multi-directional wrinkle portion 402 can be easily tensioned.

The protrusions 404 may be reduced in height toward both sides of the multi-directional wrinkles 402, and the protrusions 404 may be integrally formed by extrusion molding in the longitudinal direction of the corrugated closing plate 400 .

Since the corrugated closure panel 400 has the corrugated hollow 402a, the corrugated frame 402b is formed at the corner portion of the unit pontoon 100 even if the multi-directional corrugated portion 402 has a constant volume. It is possible to bend by 90 degrees. Even if the bending of 90 degrees is performed as described above, the rupture-type closure member 400 may be hardly broken or ruptured.

3C, the corrugated rim 402b of the multi-directional wrinkle 402 can be pressed and bent at the corner of the unit pontoon 100, and even at the corners where the load is concentrated, It can maintain performance.

When the adjacent unit pontoons 101, 102 and 103 approach and their abutment surfaces 100a and 100b are brought into contact with each other, the second plate portion 403 is brought into contact with the other unit ponton abutment surfaces 100b, And is inserted into the concave portion 130. Generally, when the joining faces 100a and 100b of the unit pontoons of the two sides face each other, the joining faces 100a and 100b are prevented from being directly touched to each other and are prevented from being damaged. In order to fill the grout material 1000, 140 may be installed.

Next, the grout material 1000 is injected into and filled in the concave portion 130 in a state where the joint surfaces of the unit pontoons 100 are in contact with each other, and the joint surface The grout material 1000 is injected and filled in the gap.

The second plate portion 403 located in the concave recessed portion 130 is buried in the grout material 1000 and fixed when the grout material 1000 is cured.

As such, when the unit pontoons 100 are in contact with each other, the corrugated closing plate 400 according to the present invention is disposed over the joining faces 100a and 100b of the unit pontoons, and thus the joining faces 100a and 100b It is possible to effectively prevent the external water from flowing into the unit pontoon 100.
