Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hold palate, and more particularly to a hold palate consisting of a number of elongated panels for closing the middle deck hold opening of a ship's hold.

When the cargo hold is opened, the conventional cargo hold cover that closes the cargo hold opening provided on the middle deck of the cargo hold is stacked on a truck and transported to the storage position. Therefore, each berth is made into a simple elongated rectangular panel with an L-shaped cross section without sufficiently attaching reinforcing members such as stiffeners to the lower surface. It is used by covering a rectangular panel and placing the short side vertically to support a rectangular panel. On the other hand, if the holds located above and below the middle deck are used as freezing holds, it may be necessary to drill a large number of openings in the roof of the middle deck in order to communicate the cold air in the upper and lower freezing holds. In such cases, in order to prevent the opening from being blocked by cargo, measures such as laying dunnage material on the roof of the hold to create a layer of cold air circulation are taken, which not only consumes labor but also wastes materials. was.

The present invention is useful in solving this type of problem that occurs with conventional hold openings used for the middle deck hold openings of ships.

The purpose of the present invention is to obtain a hold opening that is not only lightweight and convenient to operate, but also has an opening that is useful for ventilation between the holds located above and below the hold. It is in.

According to the present invention, the long sides are in the width direction of the ship,
Alternatively, a hold roof consisting of a number of panels placed side by side in a mid-deck holdway, with elongated rectangular plate sections arranged horizontally along the length of the ship, each rectangular plate section being arranged on the upper surface at relatively small intervals. A large number of strip plates 6a, 6 are attached and extend in the direction of the length L of the hatch.
b, 6c, and a large number of openings 8 bored into the rectangular plate portion at the intermediate portion of a pair of adjacent strip plates.

Now, an embodiment of the apparatus of the present invention will be described below with reference to the accompanying drawings.

Referring to Figure 1, the berth opening edge material 2 of the middle deck inside the hold
Two groups of palates 1a, 1b, 1c arranged above,
1d... and 1a', 1b', 1c', 1d'... are shown. The first group 1a', 1b', 1c'... on the right side is the one on the left side with respect to the vertical plane YY at the center of the length L of the port.
Since they have the same structure arranged symmetrically in groups 1a, 1b, 1c, ..., the first group on the left 1a, 1b,
1c,... will be explained below. Each bay palate 1
a, 1b, 1c... are made up of elongated rectangular plates with an L-shaped cross section, the long leg part 4 of the L-shaped cross section covers the port, and the short leg parts or flange parts 5 are arranged in the vertical direction, and the lower end is the edge of the port. It abuts against material 2 and supports the palate. Each of the palates 1a, 1b, 1c... is provided with a horizontal support piece 13 of a predetermined width on the outside of the corner of the L-shape, and the adjacent subsequent palates 1b, 1c, 1, respectively.
d... are configured to support the rear edge portions 11a, 11b, 11c, . Rightmost palate 1a
is equipped with wheels 12 that roll along a track (not shown) on the berth edge material 2, and is itself a trolley, and the following berths 1b, 1c, 1d, etc. are stacked and loaded one after another. It is carried to a storage position (not shown) provided at the left end of the hatch edge material 2. The right half of FIG. 1 shows an initial state in which the roof 1a', that is, the truck, carries the succeeding panel 1b' on its upper part.

As shown in Fig. 2, the palate panel 1 of the present invention
a, 1b, 1c, . . . are provided with a plurality of strip plates 6a, 6b, 6c, . ing. A plurality of ventilation holes 8 are provided between two adjacent strips. In this way, the ballast panel of the present invention alternates between strips 6a, 6b, and 6c of the same size extending in the longitudinal direction of the ballast and a large number of ventilation holes 8 arranged in the longitudinal direction of the ballast. It is constructed by arranging them.

As shown in FIG. 3, when the cargo 14 is loaded on the top surface of the cargo hatch 10 of the present invention, the lower part of the cargo 14 is supported by the strips 6a, 6b, 6c, and between the bottom surface of the cargo 14 and the ventilation hole 8. Since a large number of relatively thin spaces 9 are formed in a band shape in plan view, and the lower cargo layer of the cargo palates 1a, 1b, 1c... is communicated with the upper cargo layer,
This is advantageous when both cargo holds are used as reefer holds.

FIG. 4 shows a modification of the device shown in FIG. 3, in which a large number of rods such as square rods and round rods are attached to the upper surface of the rectangular plate portion in place of the band plates.

As described above, when using the device 10 of the present invention, the longitudinal strips 6a, 6b, 6 arranged at predetermined intervals on the rectangular plate portion of the gully panel.
c not only strengthens each forklift panel as a stiffener, but also acts as dunnage laid on each forklift panel. Therefore, the elongated thin space 9 and the opening 8 formed by the two adjacent strips in the lower part of the cargo 14 are useful for ventilation between the holds located above and below the hold palate.
