Description

Lashing bridge

The present invention relates to a lashing bridge, and more particularly, a "V" shaped support is installed in the stern direction of both sides of the lashing bridge installed on the upper deck of the container ship, and the hole for container management and repair on the bow side. By installing each of these supporting plates to absorb the lateral force applied to the lashing bridge, as well as to reduce the weight of the lashing bridge itself, and to facilitate the manufacturing and installation of the lashing bridge, In particular, when the container loaded on the container ship is a refrigerated container, the invention has been invented to smoothly perform the operation and maintenance for the front panel.

LASHING BRIDGE, which is usually installed on the upper deck of container ships, including the deck of a large cargo ship or the top of a hatch cover, is a heavy structure for container safety. Most large container ships are designed to increase container load / stage. Is applied.

That is, a lashing bridge is installed to safely secure many containers loaded on the deck of a large cargo ship or on the top of a hatch cover or on the upper deck of a container ship.

As such a lashing bridge for container ships, Korean Laid-Open Patent Publication No. 1999-703411 is disclosed.

That is, the lashing bridge is installed in the transverse direction of the vessel to fix the container, wherein the lashing bridge comprises a column of two rows and a sidewalk fixed between the columns as a whole.

The columns of two rows are arranged in a rectangular shape as a whole, and between the columns, diagonal struts are inclined to absorb lateral forces acting on the lashing bridge during the voyage of the container ship.

In addition, in order to absorb the lateral force acting on the lashing bridge, a plate plate may be used to seal the entire space between the columns instead of the diagonal strut. In this case, like the diagonal strut, the plate plate may be disposed between the columns only on one side of the lashing bridge. It is installed alternately.

However, when adopting a crutch or plate plate to absorb the lateral force acting on the lashing bridge of such a structure has the following problems.

Since one of the sides of the lashing bridge, the column between the crutch or the plate plate is substantially sealed, in the case of a refrigeration container or the like supported by the lashing bridge, its maintenance and repair is difficult.

When absorbing the lateral force acting on the lashing bridge by the crutch or plate plate, there is a problem that the total weight of the lashing bridge is increased due to the weight of the diagonal crutch or plate plate. This problem is particularly problematic as the lashing bridge is formed in three or more stages.

In the case of diagonal struts or plate plates, they must be fixed to the lashing bridge and the deck of the ship or to the top of the hatch coaming and upper deck, but since there are more parts to perform such fixing work (mostly welding work), the manufacturing work of the lashing bridge and the ship This slows down the task of installing a lashing bridge.

Accordingly, in Korean Patent Registration No. 10-0588380, two rows of columns 100 and columns of two rows are installed in a transverse direction of a vessel to be fixed to a container as shown in FIG. In the lashing bridge comprising at least one or more sidewalks 200 is fixedly provided at a predetermined height horizontally therebetween; Provide at least one pair of support zones 300 having a "∧" shape fixed to both sides of the lashing bridge so as to absorb the lateral force acting on the lashing bridge, and the sidewalk 200 is provided at least two stages. The upper height of the support zone 300 is not lower than the height of the uppermost press section of the sidewalk portion 200, the support zone 300 is made of a square pipe formed with a rectangular hollow therein, and also the support zone 300 is provided with at least two pairs, and the lashing bridge is structurally separated by at least two divided lashing bridges, the column forming the rectangular vertex of the columns of the container protruding in the longitudinal direction of the ship The support 131 presents an extended configuration.

In this case, some of the columns 100 are container guide pillars 110 for container installation, and some are hatch cover guide pillars 120 which serve to guide and position the hatch cover, which is a heavy object, safely to its position. In addition, the corner columns 130 forming the vertex of the rectangle of the columns 100 are protruded in the longitudinal direction of the vessel is a container support 131 for supporting the container is formed extending.

However, when a refrigerated container is shipped to a vessel with a lashing bridge having such a configuration, the front panel of the refrigerated container is covered by a "∧" shaped bevel support installed in the bow portion, and thus, obstacles in managing / repairing the frozen container. In addition, in consideration of the lashing force (LASHING FORCE) acting on the lashing eye (LASHING EYE) installed in the top floor walkway for each container width, the "∧" form is to support the concentration at the upper vertex. There is a problem that the power is not distributed.

In addition, since the diagonal support is installed on the upper surface of the hatch coaming in the form of "∧" at the tail end of the lashing bridge, there are many welding places and welding quantity, and the lower reinforcement structure has a complicated problem. Since the bracket is connected between the US pillars, there is a problem that a lot of welding work is required during the installation of the lashing bridge, resulting in a large production cost and a large weight.

The present invention has been made in order to solve such a conventional problem, install a "V" shaped support in the stern direction of both sides of the lashing bridge installed on the upper deck of the container ship, and the hole for container management and repair on the bow side By installing each of these supporting plates, the transverse force applied to the lashing bridge can be absorbed more efficiently, and the weight of the lashing bridge itself can be reduced, and the welded portions of the lashing bridge are reduced. Lashing bridge that can be easily manufactured and installed, and especially when the container loaded on the container ship is a refrigerated container, the operation and repair of the shear operation panel can be smoothly performed through the hole for hole management and maintenance of the perforated plate on the support plate. The purpose is to provide.

The present invention for achieving the above object is a lashing bridge having a form consisting of two rows of columns, sidewalks and support members and installed in the transverse direction of the vessel to fix the container, the support member is a "V" shaped support And the support plate, wherein the “V” shaped support is installed in the stern direction of the double row column, and the support plate is provided at the bow side of the double row column by providing two container management and repair holes in the upper and lower parts. .

As described above, according to the present invention, the support member fixed to both sides of the two-column column of the lashing bridge is composed of a "V" -shaped support and a support plate, and the "V" -shaped support is installed in the stern direction of the two-column column, The support plate is provided with two container management and repair holes in the upper and lower parts and installed on the bow side of the double row column to more efficiently absorb the lateral force applied to the lashing bridge and reduce the weight of the lashing bridge itself. In addition, it is possible to reduce the welding area performed in the ship, so that the manufacturing and installation of the lashing bridge can be easily performed. Especially, in the case where the container loaded on the container ship is a refrigerated container, the operation and repair of the shear operation panel is supported.
