Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a floating floor panel on the deck of a ship such as a chemical tanker, an oil tanker, a cargo ship, a passenger ship, and a cargo passenger ship.
[0002]
[Prior art]
Conventional marine floor structures require a combination of porous parts such as fiber and lightweight calcium silicate plates and large parts made of steel sheets and concrete from the viewpoint of heat insulation, sound insulation and vibration proofing. Each thickness is adjusted according to the performance. As for the construction method, in Japanese Utility Model Laid-Open No. 58-172650, a steel plate having an engaging stepped portion and a protruding piece is fixed to the surface of the mineral fiber board, and the stepped portion and the protruding piece are respectively fixed at corresponding positions. A panel having a through hole is proposed, and a method of fixing with a screw through a through hole of a protruding piece of another floor panel adjacent to the engaging step is shown.
[0003]
However, there is a disadvantage in that a through-hole formed in advance is displaced due to a slight displacement of the arrangement position of the panel, which hinders the screw fixing work. Moreover, in the said utility model, since the mineral fiber board used for the core material of a panel is using the orientation direction of a fiber in the direction parallel to a surface steel plate in the center part of a panel, with respect to the compressive load from a panel surface There is a drawback that the body is easily deformed and the body sinks when it is walked on the flooring material, which causes discomfort.
[0004]
Japanese Utility Model Laid-Open No. 61-20498 proposes a method of fixing a plurality of steel plate panels provided on a deck with a steel plate provided with rock steel on a rock wool with a jig having a key-shaped claw. However, in order to fix the steel plate panels arranged with this jig, it is necessary to drill holes in the panels arranged next to each other and embed key-shaped claws, so that the construction efficiency can be improved. There is a disadvantage of not. Further, the fixing jig having the key-shaped claws protrudes on the surface of the steel plate panel after being fixed, and the surface floor material cannot be applied unless it is buried in the deck composition.
[0005]
[Problems to be solved by the invention]
Accordingly, the present invention is to provide a floor panel that is easy to construct in addition to the above-mentioned problems in a floating floor structure for a ship, and further is a floor panel using an inorganic fiber board, which is a compressive load from the floor surface. It is an object of the present invention to provide a floating floor panel that has a small sinking and does not have a step difference in joints between adjacent panels.
[0006]
[Means for Solving the Problems]
In order to solve the above problems, a floating floor panel for a ship according to the present invention is a floating floor panel in which an inorganic fiber board is inserted and bonded via an adhesive to the lower part of a flat box-shaped steel plate having an open bottom surface, A claw is projected outward from the lower edge of the opening edge of the steel plate, and is connected to an adjacent floating floor panel through this claw, and this claw is connected to the inorganic fiber board of the adjacent panel. By inserting the panels, the panels can be joined to each other, and construction can be performed while maintaining the level of the panels without much effort.
[0007]
The present invention is the floating floor panel for a ship described above, wherein the pawl is integrally formed or joined to the steel plate. That is, a flat steel plate is bent and formed into a flat box shape having an open bottom surface, and at the same time a steel plate provided with a pawl or a steel plate previously bent into a flat box shape with one open is welded or the like. By using a steel plate joined with claws made of letter-shaped steel material, this pawl engages with the lower edge of the opening edge of the adjacent floating floor panel to eliminate the joint step between adjacent panels, making installation easier It is to have done.
[0008]
Further, the present invention is the above-mentioned floating floor panel for ships, wherein the inorganic fiber board is made of rock wool or glass fiber having fiber orientation, and the fiber orientation direction of the inorganic fiber board is the upper surface of the steel sheet. It is characterized by being perpendicular (the load direction and the fiber orientation direction are the same).
[0009]
This is because by making the fiber orientation direction of the inorganic fiber board perpendicular to the upper surface of the steel sheet, the spring constant of the fiber board is increased, the deformation against the compressive load from the panel surface is small, and the sinking is reduced on the entire floor panel. it can. Further, when the claws protruding outward from the end portions are bitten into the inorganic fiber board which is the core material of the panel arranged adjacent to each other, the fiber orientation direction of the fiber board is perpendicular to the steel plate, so that the spring Large constants support the mass of the panels, eliminating the need for surface steps and maintaining the level.

In the floating floor panel of the present invention, the adhesives 14a and 14b to be used can be any of inorganic adhesives such as sodium silicates, and organic adhesives such as resin and rubber. The adhesives 14a and 14b are bent into a flat box shape, and are sprayed on the inner side surfaces of the steel plates 13a and 13b having claws protruding outward from the lower edge of the opening edge in advance or by a method using a brush or a spatula. Apply. The coating amount is 100 to 500 g / m ² when an organic adhesive is used, but is preferably 100 to 300 g / m ² in view of fireproof performance. In the case of using an inorganic adhesive, 300 to 600 g / m ² is preferable from the viewpoint of adhesive strength and cost.
[0014]
FIG. 4 is an enlarged view of a claw portion that is integrally formed or joined to the steel plates 13a and 13b in advance. The claws are formed integrally when a sheet of steel plate that has been cut to a size including the size of the pawl portions in advance is bent into a flat box shape, or a steel material whose cross section has been processed into an L shape in advance. Attached by welding or the like to a predetermined position of steel plates 13a and 13b that are cut into a predetermined length or bent after flat steel is cut into a predetermined length and bent into a substantially U-shaped cross section. It is a thing.
[0015]
As described above, the adhesives 14a and 14b are applied to the inner surfaces of the steel plates 13a and 13b with the claws 15a and 15b formed by bending as described above. The inorganic fiber plates 12a and 12b having fiber orientation are cut into a predetermined width corresponding to the thickness of the floating floor panel, and the upper surfaces of the steel plates 13a and 13b are perpendicular to the fiber orientation direction (the load direction and the fiber orientation direction are the same). Install and bond without gaps. At this time, the inorganic fiber plates 12a and 12b that are in contact with the bent portions of the steel plates 13a and 13b that are bent into a flat box shape are shaved by the thickness of the steel plates, and the steel plates are joined when the adjacent floor panels are joined. It is desirable that the inorganic fiber boards 12a and 12b are in contact with each other on the lower side of 13a and 13b, and that the caulking 15a and 15b are engaged with the lower edge of the opening edge of the adjacent floating floor panel.

FIG. 5 is a front view when two floating floor panels of the present invention are joined. It shows that the pawls protruding outward from the end faces are attached at positions where they do not interfere with each other when two adjacent floor panels are joined. When actually constructing the floating floor panel of the present invention on the steel deck 23 of a ship, the distortion and smoothness of the steel deck 23 are corrected in advance, and then the moisture deck and foreign matter are removed. The floating floor panel provided at the end such as a corner may not have a protruding claw. According to the arrangement order, the claws 15a and 15b are arranged while being inserted into the inorganic fiber boards 12a and 12b which are the cores of the floor panels arranged adjacent to each other.
