[Detailed description of the invention]

(Industrial Application Field) This invention can store moving cargo, various products, etc. inside, be loaded onto a train, ship, freight truck, etc. for transport, or be stacked indoors or outdoors for storage. The purpose of the present invention is to provide a container that is strong, lightweight, and inexpensive to manufacture, with regard to the structure of a multipurpose container that can be used as a warehouse. (Prior Art) Many conventionally known containers, especially relatively large containers for storing import and export products, have fork pockets 11 as shown in FIG.
Lower girder 11 with a, upper girder 12, and corner frame 13
, the lower beam 14, the upper beam 15, the side column 16 provided between the lower beam 11 and the upper beam 12, the end column 17 provided between the lower beam 14 and the upper beam 15, and the upper beam 15. A roof beam 18 bridged between the girders 12, 12, an inner side lining 19 and an outer side wall 23 via the side columns 16, an inner end wall cladding 20 and an outer side wall cladding 20 via the end columns 17, A large number of floor beams (not shown) bridged between the end wall 24, the inner roof plate 21 and roof 22 via the roof beam 18, and the lower girder 11.11, and the floor slab laid on top of the floor beams. (Illustration omitted) (November 30, 1970, published by Nikkan Kogyo Shimbun, "Logistics Management Handbook" 622
(See pages 623 to 623). (Problems to be Solved by the Invention) Therefore, as mentioned above, conventional containers not only require a lot of time and effort in assembling them, from design to material procurement to processing man-hours, and also require product inspection. The number of fork pockets (fork insertion holes in forklifts) that can be installed is limited due to the need to maintain strict sealing, rainwater can easily enter from the processing area, and the number of fork pockets (fork insertion holes in forklifts) is limited in order to maintain strength. In addition to general problems such as inconvenience in transportation and handling, the fundamental problem is that it is necessary to use a large number of aggregates to maintain strength, resulting in high costs and difficulty in reducing weight. I'm holding it. (Means for Solving the Problems) The present invention was devised after various studies to solve the various problems mentioned above. Alternatively, a rectangular body of a predetermined size is formed by bending a corrugated board of a predetermined strength and having a corrugated shape of different heights in a direction perpendicular to the crests and troughs of the corrugation, and keeping the cross section of the board at the bent portion waveform. The present invention also relates to a container structure in which a flat plate is attached to the inner bottom portion of the container, and at least one of the wall plates that close the openings on both sides is configured to be openable and closable. Further, the present invention bends a corrugated board of a predetermined strength and a corrugated board of a predetermined strength and a corrugated board of a predetermined strength and a corrugated board of different heights in a direction perpendicular to the peaks and troughs of the waveform, and furthermore, the cross section of the board at the bent portion is made into a waveform. A rectangular body of a predetermined size is formed by holding a plurality of modules, and a flat plate is attached to the inner bottom of the module.The openings of each module are butt welded to each other, and the openings on both sides are closed. The present invention also relates to the structure of a container in which at least one of the wall plates is configured to be openable and closable. Below, the specific contents of the present invention will be explained in Sections 1 to 5.
To explain based on the embodiment shown in the figure, reference numeral 1 indicates a module formed into a rectangular shape by a corrugated plate, and the module 1 is a corrugated plate having a predetermined strength and has a corrugated shape, and has peaks 2 and slopes. Part 3
and troughs 4, bent in a direction perpendicular to the crests and troughs of the waveform as a whole, and keeping the cross section of the plate at the bent portions waveform to form a rectangular body of a predetermined size as shown in FIG. is formed, and its bent butted ends are welded together at the bottom. The embodiment shown in FIG. 1 is a longitudinal cross-sectional view taken along the line A--A in FIG. They are welded together 5' to form the base of one container. 6 is a flat plate, in this case each module 1
The container is constructed by welding the floor plate at appropriate points on the inner bottom surface of the container to maintain the strength of the container itself. Spacers 7 are arranged at predetermined intervals to prevent the corrugated plates from interlocking with each other and becoming difficult to separate when containers are stacked, and also to facilitate the insertion of forks during cargo handling using a forklift. . In this case, spacer 7 is attached to each module 1.
A more favorable result can be obtained in the sense that the welding strength can be improved or the joining effect can be more perfected by attaching it so as to match the joint part 5' of.... Reference numeral 9 denotes a door attached to the door so as to be openable and closable with hinges 8, 8, and in this embodiment is a double door. Reference numeral 10 indicates a mirror plate integrally attached to the opposite side of the door 9. With the container configured as described above, even if only one container is handled, it is not only easy to insert a fork claw into the bottom of the container, but also the fork claw can be easily inserted into the bottom of the container, for example, as shown in FIG. Even when stacked, the concave and convex portions of the corrugated plates engage with each other, so not only is there no shift of the cargo during transportation, but also there is no need for a loading table or stopper, which is extremely convenient for cargo handling operations. Furthermore, in the embodiment shown in FIG. 1, a case has been described in which a single container is constructed by combining a plurality of modules 1, but the present invention is not limited to this, and a container may also be constructed by only one module. good. Further, the container shown in FIG.
Only the central peaks 2a... of the modules 1 that are aligned and continuous with each other are formed to be lower than the other peaks 2 by a height P, thereby conversely making the other peaks 2... Spacer 7 in the above embodiment
It is constructed so that it can be substituted for...
This also eliminates the work of attaching the spacers 7, etc. The embodiment shown in FIG. 5 also has a structure in which three modules 1 are welded together 5' with their respective openings aligned to form one container, as in the case of FIG. 1. However, the container is not necessarily limited to this, and it is also possible to configure the container with only one module. In both the embodiments shown in FIG. 1 and FIG. 5, the wall plates that close the openings on both sides of the container include a mirror plate 10 on one side and a door 9 on the other side, or both doors 9 that can be opened and closed, and at least One side can be opened and closed freely. Furthermore, to explain the method of processing the corrugated plates forming each module 1 described above, as shown in FIG.
A lower die 31 having alternating peaks and valleys that match the waveform of a and a curved concave portion 31a for bending the corrugated board 1a in a direction perpendicular to the peaks and valleys, and the lower die 31 as described above. Using an upper die 32 having an opposite waveform convex portion 32a on the lower end that matches the concave portion 31a, a corrugated corrugated board 1a of a predetermined strength or a corrugated board 1a of a predetermined strength and a corrugated shape of different heights is made. The crests and troughs of the waveform are placed so as to match the waveforms on the upper surface of the lower mold 31, and the upper mold 32 is dropped, and the crests and troughs of the waveform are aligned at points a and b in order, for example, as shown in B and C of the same figure. and bent in a direction perpendicular to the valley, and further supported by a gate-shaped frame (not shown)
Press the parts d and d sequentially to make each bent part a to d.
A rectangular body of a predetermined size is formed while keeping the cross section of the plate waveform, and the module 1 is formed by welding the abutted ends 1b. Note that the corrugated plate 1 forming the module 1 described above
The material for a may be an ordinary steel plate, preferably one having corrosion resistance. The thickness of the corrugated board 1a is also related to the size of the container, but the following standards serve as a rough guide when the opening/closing door of the container is in the front.

[Table] (Function) In the configuration of the above-described embodiment, at least one door 9, which can be opened and closed, is opened to store cargo such as various products on the internal floorboard 6, and the door 9 is closed again to store the cargo. . Containers are placed indoors or outdoors as necessary, and transported by train, ship, automobile, etc. as necessary. At that time, a fork claw should be inserted into the valley on the bottom of the container to carry out cargo handling operations, and it is also possible to stack multiple containers on top of the container (see Figures 3 and 4).
(see figure). (Effects of the Invention) As described above, the present invention provides a corrugated board having a predetermined strength with a corrugated shape or a corrugated board with a predetermined strength having a corrugated shape of different heights in a direction perpendicular to the crests and troughs of the corrugation. Firstly, since it uses a module that is bent and made into a rectangular body of a predetermined size by keeping the plate cross section of the bent part in a wave shape,
There is no need to use multiple reinforcing materials like in conventional containers, and the strength in the stacking direction is significantly stronger than that of conventional stress-concentrating structures on the four corner supports. If necessary, multiple modules can be connected together to easily produce a container of a desired length.The number of processing steps is extremely small, and it is also lightweight. The joint part is an extremely easy part to weld, and since the side parts are in the vertical and vertical directions, the degree of erosion caused by rainwater etc. is significantly advantageous compared to conventional ones. Second, since the main material is corrugated board, it is not only possible to insert fork hooks or wire ropes for hanging as needed, but also when multiple containers are stacked or placed next to each other, corrugated board can be used as the main material. As a result of the uneven portions of the plates interlocking with each other, there are various beneficial effects such as eliminating the risk of accidents such as cargo shifting, especially during transportation. In this embodiment, both bent ends of the corrugated plates are butt-welded to each other at the bottom, but this is not necessarily the case, and it is also possible to do no welding or to maintain some distance between them. Overall, changes in design are permitted within a range that does not depart from the technical idea of the present invention. (Example)

[Table] When we manufactured containers using the three types of modules mentioned above and subjected them to actual harsh use for about three months, we found that No. 3 had sufficient strength and was visually appealing. There is not even a dent. No. 1 had a slight dent on the top and side surfaces, but it was negligible and the strength was also reasonable. No. 2 has only a few dents on its exterior, but it feels a little unstable when stacking containers and the storage load is significantly heavier than standard. In each of the above examples, when compared with conventional containers of the same volume, the plate thickness used in conventional containers is approximately 3.2 to 3.8 (m/m), so there is not such a drastic difference in plate thickness. Best of all, it does not require any reinforcement material at all, so it is structurally
In addition, significant benefits were seen in all aspects, both in terms of cost and functionality.
