DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a floor of a cold-insulating box, which is attached to a bed of a truck or a freight car and used for transporting frozen / refrigerated cargo.

2. Description of the Related Art Conventionally, as a floor of this type of cold insulation box body, for example,
As shown in the figure, a floor panel (21) made of an extruded aluminum material is provided, and in this floor panel (21), a side-by-side load support portion (22) that is long in the longitudinal direction and has a predetermined height. (22) is provided, and a space section (25) for inserting a load moving device having a vertically movable load moving table is provided between required two load supporting sections (22) (22) facing each other. The stepped portion (26) is provided on each side edge of the opening of the space portion (25).
(26) is provided, and these space (25) and step (26) are provided.
A stainless steel guide rail (24) having a horizontal cross section is fitted into the (26) as a load moving device supporting member, and the overhanging wall portions (27) (27) on both sides of the upper end of the guide rail (24) are screwed (29) (29). )
It was fixed to the steps (26) (26) by.

However, since the stainless steel guide rail (24) has a cross-sectional shape in such a conventional floor of the cold insulating box body, many materials are used and the weight of the guide rail (24) is large. Since it is heavy, there was a problem that the weight of the cool box could not be reduced. Also, due to manufacturing errors, the guide rail (2
The level of the upper surface of the overhanging wall parts (27) (27) of 4) does not match the level of the upper surface of the cargo support parts (22) (22) of the floor panel (21), and the former level is the latter level. If the load is higher, there is a problem that the bottom surface of the cargo may be damaged when the cargo is placed on the upper surface of the floor panel (1) or moved. Further, a gap (28) (28) is easily formed between the tip of the overhang wall (27) (27) of the guide rail (24) and the side surface of the step (26) (26), and these gaps ( 2
8) Water penetrates between the guide rail (24) and the floor panel (1) from (28) and stays there due to the capillary phenomenon, so that so-called skimmer corrosion may occur, resulting in poor durability. There was a problem.

The purpose of this invention is to solve the above problems of the prior art,
The material used for the load-carrying device support plate is very small, and as a result, it is possible to reduce the weight of the box for keeping cold, and the load-carrying device support plate does not appear on the upper surface of the load supporting portion of the floor panel.
Therefore, when placing or moving a load on the upper surface of the floor panel, there is no risk of damaging the bottom of the load at all,
Moreover, since the water that has entered the gap between the load transfer device support plate and the floor panel is quickly discharged, there is no risk of crevice corrosion, and it is possible to provide a durable box floor for cold storage. And there is.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides a floor panel made of an extruded aluminum material with a large number of parallel load supporting portions which are long in the longitudinal direction and have a predetermined height. 2 of all the cargo supports that face each other
A space for inserting a load moving device having a vertically movable load moving base is provided between the two load supporting parts, and both load supporting parts are vertically opposed to each other and outward from the upper ends thereof. It has a horizontal wall that extends and an inward convex portion is provided at the lower end portion of the opposing wall over the entire length of the floor panel and at approximately the same level as each other, and these convex portions move the load made of wear-resistant metal. The gist is the floor of the cold-insulating box body in which the device support plate is handed over and arranged near the bottom of the space.

Here, the load transfer device support plate is made of wear-resistant metal such as stainless steel plate, and is usually flat plate, but it may be formed in a substantially horizontal cross section.

Operation When a load is placed on the floor of the cold-insulating box having the above-described structure, for example, by a forklift, the load is supported by the parallel load support portions of the floor panels. However, with a forklift, the load can only be placed on the floor panel in front of the cool box. In order to move the load to the back of the cold insulation box, the load moving table 2 of the load moving device is inserted into the space between the two opposing load supporting portions. At this time, the level of the upper surface of the load transfer table of the apparatus is lower than the level of the upper surface of the load support portion. After the insertion, the lever of the device is operated to raise the load moving table so that the level of the upper surface of the load moving table becomes higher than the level of the upper surface of the load supporting portion, and the load is lifted. Then, in this state, move the load carrier forward, move the load to the back, return the lever there, lower the load carrier, put the load on the floor panel, and repeat this operation. Thus, the loads are arranged in order on the floor of the cold insulation box.

Embodiment Next, an embodiment of the present invention will be described with reference to the drawings.

In FIG. 1 and FIG. 2, the floor of the cold-insulating box body according to the present invention has a floor panel (1) made of an aluminum extruded mold material, which is long in the longitudinal direction of the panel (1) and has a predetermined height. Is provided with a number of parallel cargo supports (2) (3).

Of the cargo support portions (2) and (3), two required cargo support portions (2) and (2) facing each other are formed in a hollow shape having a rectangular cross section, and these cargo loads are in the hollow shape. A space portion (5) for inserting a load moving device (10) having a load moving table (11) that can be raised and lowered is provided between the support portions (2) and (2). Other cargo support (3)
(3) has a substantially T-shaped cross section.

The two hollow cargo support parts (2) and (2) respectively include vertical facing walls (6) and (6), horizontal walls (7) and (7) extending outward from their upper ends, and horizontal walls ( 7) has vertical walls (16) and (16) extending downward from the outer ends of (7), and the upper surface of the horizontal wall (7) of the hollow cargo support (2),
The upper surface of the horizontal wall (17) of the cargo support portion (3) having a substantially T-shaped cross section is at the same level as each other.

Further, inward projections (8) and (8) are provided at the lower end portions of the opposing walls (6) and (6) along the entire length of the floor panel (1) and at substantially the same level, and these projections (8) (8) A load transfer device supporting plate (4) made of stainless steel having abrasion resistance is passed to (8), and both ends thereof are screwed (9).
Stopped by (9), this support plate (4) is located near the bottom of the space (5). A relatively wide void (14) is provided between the load transfer device support plate (4) and the floor panel (1), and this void (1
4) Inside, the floor panel (1) has a convex portion (13) for maintaining a gap.
Are provided so as to project upward, and the central portion of the support plate (4) is received by the convex portion (13).

For example, in order to move the load (12) placed on the load supporting portions (2) and (3) of the floor panel (1) by a forklift (not shown), as shown in FIG. The load transfer table (11) of the load transfer device (10) is inserted into the space (5) between the support parts (2) and (2). At this time, the level of the upper surface of the load transfer table (11) is lower than the level of the upper surfaces of the load support parts (2) and (2).

Next, as shown in FIG. 3, after the insertion, the lever (15) of the load transfer device (10) is operated to raise the load transfer table (11) so that the level of the upper surface of the load transfer part (2) rises. )
The load (12) is lifted so as to be higher than the level of the upper surface of (2), and in this state, the load transfer table (11) is moved forward to move the load (12). After moving, return the lever (15) to its original state and
1) is again lowered into the space portion (5), and the load (12) is placed on the load support portions (2) and (2).

Effect of the Invention As described above, the floor of the cold-insulating box according to the present invention has a floor panel made of aluminum extruded material and a large number of parallel load-carrying portions having a predetermined height in the length direction of the floor panel. A space part for inserting a load transfer device having a load transfer table that can be raised and lowered is provided between two required load support parts facing each other among all the load support parts.
Each of the load supporting portions has a vertical facing wall and a horizontal wall extending outward from the upper ends thereof, and an inward convex portion is provided at a portion near the lower end of the facing wall over the entire length of the floor panel. Are provided at substantially the same level, and the load transfer device support plate made of wear-resistant metal is passed over these protrusions,
