Description

{FLOOR STRUCTURE FOR SHIP}

The present invention relates to a bottom structure for a ship, and more particularly, to a bottom structure for a ship which is installed at a predetermined distance from a bottom surface in a state where a device such as a duct or a cable tray is installed on the bottom.

Generally, a cable tray is installed for the purpose of protecting a cable in a bundle arrangement of various cables such as ships, industrial sites, and buildings.

These cable trays serve not only to protect the cables but also to secure the cable routing path.

The cable tray may have a tray cover in the form of a flat plate for protecting the cable installed therein.

The applicant of the present application has filed a patent application relating to a cable tray disclosed in the following Patent Documents 1 to 3 and the like.

In addition, ducts of various shapes and sizes are installed on the ship.

Therefore, ducts and cables are installed on the bottom surface of the cabin, especially the electrical room where the electrical equipment is installed, and floor structures are installed at a certain height from the bottom surface.

The ship floor structure according to the prior art has a structure in which a support bar is installed at regular intervals and a square panel formed in a predetermined standard is installed on the support bar.

However, since the marine floor structure according to the prior art is provided with the support bars at intervals of about 600 mm, there is a problem that it can not be applied to a large-sized duct having a diameter of several thousands mm or more, or an electric room having a cable tray installed therein.

In addition, the marine floor structure according to the related art has a problem in that the structural strength is weak and the structure is damaged or damaged in the process of moving an object having a large load using the trolley.

It is an object of the present invention to provide a floor structure for a ship which can be applied to a cabin having a large duct or a cable tray installed on the floor.

Another object of the present invention is to provide a marine floor structure capable of increasing structural strength.

In order to achieve the above object, a floor structure for a ship according to the present invention comprises a vertical support which is manufactured at a preset height and is installed in a vertical direction on a floor of a cabin, a horizontal support horizontally installed on the upper part of the vertical support, A plurality of bottom plate assemblies formed in a grid shape and provided on upper portions of the horizontal supports, and a plurality of flat plate assemblies provided on respective openings formed on an upper surface of the frame assembly.

The horizontal support body includes a plurality of main girders installed vertically and horizontally on the upper ends of the respective vertical supports, a floor beam spaced apart from the main girders by a predetermined interval in the horizontal direction, And a vertical girder.

The frame assembly includes a plurality of uni-strut channels arranged in a horizontal direction and a vertical direction so as to form a grid shape, and a fixing module for fixing the bottom plate assembly is installed at a portion where the respective uni- .

The fixing module includes a first fixing member installed on an upper surface of a portion where each uni-strut channel is installed in the lateral and longitudinal directions, and a second fixing member coupled to an upper portion of the first fixing member, And a second fixing member on which the second fixing member is formed.

And a rubber gasket is formed on an upper portion of the fixing module, the rubber gasket being formed in a shape corresponding to an upper surface of the second fixing member.

And a fixing plate is installed on the lower surface of the portion where each uni-strut channel meets or the portion where the uni-strut channel and the vertical girder of the horizontal support are coupled, so that each uni-strut channel can be stably connected.

Wherein the bottom plate assembly comprises a coupling frame coupled to an upper portion of a horizontal and a longitudinal uni-strut channel of the frame assembly and having opposite ends respectively coupled to coupling projections of the module, And a bottom plate installed in the fixed frame.

The present invention is characterized by further comprising a door that is installed to be openable and closable.

As described above, according to the present invention, the floor structure can be installed by avoiding interference with ducts or cable trays installed at the bottom of the cabin and spacing the floor from the floor by a predetermined height.

According to the present invention, since the vertical support and the horizontal support are used to increase the structural strength of the electronic equipment, it is possible to improve the stability even when a large load is installed inside the cabin .

Thus, according to the present invention, the space utilization under the bottom structure of the ship can be improved and the maintenance work can be easily performed.
