JPH03182894A - Cooler room construction method for freezing carrier - Google Patents

Abstract

PURPOSE:To enable construction in a narrow space by unitizing a cooler room front surface wall for the star board and port sides so as to be mounted as for the cooler room surface wall over the grating deck for the cargo hold of a freezing carrier. CONSTITUTION:Both wooden veneers 2 and wooden sparrings 3 are fixed onto each wooden joist 1 by screw nails 4 so that a panel 5 is thereby made. The panel 5 is then cut off to dimensions as required to be turned to be a front surface wall 8 for a cooler room 7 at the star board and port sides over the grating deck 6 so that the panel 5 is thereby fixed onto each steel pillar 9 by bolts and nuts 10. In addition, a protective board 11 and a metal net 12 are mounted onto the lower section and the upper section respectively. This thereby enables construction even in a narrow space.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method of constructing a front wall of a cooler room on a grating deck in a cargo hold of a reefer ship.

[Prior art] Conventionally, the construction method for this type of cooler room front wall was to weld steel pillars between the grating deck and the upper heat insulation deck at regular intervals on both sides of the grating deck, similar to the central part. There is a known construction method in which wooden joists, wooden plywood, and wooden sparrings are fixed in that order with screw nails, and a galvanized steel plate is attached to the lower part and a wire mesh is attached to the upper part.

[Problems to be Solved by the Invention] In the construction method described in the conventional technology, the inner dimension from the top surface of the heat insulating material fixed to the rear steel bulkhead of the cooler room on the grating deck to the front surface of the cooler room is The problem is that the cooler room requires the minimum necessary space to enter the cooler room and perform installation work, and the lengthwise dimension of the cooler room cannot be reduced.

This invention was made in view of the above-mentioned problems of the conventional technology, and its purpose is to provide a construction method that can be carried out even if the space inside the cooler room on the grating deck is narrow. This is what I am trying to do.

[r! Means for Solving Problem R] In order to achieve the above object, the front wall of the cooler room on the grating deck in this invention has wooden plywood and wooden sparrings fixed to the wooden joists with wooden screws or screw nails. The panel is made up of a protective steel plate and a wire mesh, and the panel is cut to the specified dimensions and inserted into the front wall of the cooler room from the cargo hold side.
Fasten to the i & pillar with bolts and nuts,
It consists of a protective steel plate on the bottom and a wire mesh on the top.

[Function] The front wall of the cooler room configured as described above can be easily fixed from the cargo hold side even if the space inside the cooler room is not large enough, and it is also easy to maintain the equipment in the cooler room. If the need for inspection arises, this is done by removing the panel's mounting nuts and removing the panel.

[Example code] Examples will be described with reference to the drawings.

In Figures 1 and 2, a wooden base plate 2 and a wooden sparring 3 are fixed to a wooden joist 1 with screw nails 4, and a panel 5
Manufacture. The panel 5 is cut to the desired dimensions for the front wall 8 of the front wall of the cooler room on the grating deck 6, and the panel 5 is fastened to the steel pillar 9 using bolts and nuts.
Fixed with 10, protective copper plate IL on the bottom, wire mesh 1 on the top
2 is attached and used.

[Effects of the Invention] Since the present invention is configured as described above, it produces the following effects.

The cooler room on the grating deck can be easily installed from the cargo hold side because it is unitized, even if there is not enough space for a person to enter the cooler room and perform installation work.

In addition, when maintaining or inspecting the equipment in the cooler room, remove the nuts that attach the panel.
The equipment can be easily accessed.
