Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a steel in which a side wall panel is tilted slightly outward from a vertical posture in which it is erected on the lower waist side so that the lower frame of the side wall panel is engaged with the lower waist side. Made of shipping containers.

[Prior art]

Without using connecting fittings such as bolts,
Various steel transportation containers have been proposed in which a panel serving as a side wall and a lower waist serving as a floor can be assembled and disassembled. 4 to 7 show a conventional steel transportation container C '.

In this conventional steel transport container C ', a total of four panels are vertically erected on the upper surfaces of the four side parts of the lower waist 13 which is the floor of the container, and the side parts of each panel are connected to each other. Then, it is formed into a rectangular tubular box shape.

The four side wall panels are composed of a side panel P1 arranged in the longitudinal direction of the lubricant 12 and a toe panel P2 arranged orthogonal to the longitudinal direction of the lubricant 12. At the lower end edges of the side panel P1 and the toe panel P2, the reinforcing lower frame 1
9 is fixed.

The lower back 13 includes a plurality of sliding members 12 arranged at equal intervals in parallel, a corrugated plate-like floor member 18 arranged on the sliding member 12, and a lower end edge of the toe panel P2. It has a toe grip angle 11 for locking and a side grip angle 21 for locking the lower end edge of the side panel P1.

As shown in FIG. 4, the toe grip angle 11 has a horizontal portion 14 and a pair of vertical walls 15 and 16 rising from both ends thereof, and a vertical wall 16 positioned outside.
The upper end of the toe panel P
It is a wedge-shaped portion 17 for locking 2.

As shown in FIG. 5, the side grip angle 21 has bending pieces 22 and 23 that are alternately bent downward and upward at one edge, and faces the inside of the bending piece 23 that is bent upward. A cut-and-raised piece 24 is erected vertically from the horizontal portion 25. The side grip angles 21 are placed on the sliding members 12, 12 located at both ends of the lower waist 13, respectively, and the bent pieces 22 are bent downward.
Is fitted to one of the flanges 12a of the lubricants 12, 12 and coupled, and the flat plate portion 25 is spot-welded to the other flange 12b to form the lubricant 12
Is integrated with. The bent piece 23 bent upward is slightly tilted inward so that the lower frame 19 of the side panel P1 fitted between the bent piece 23 and the cut-and-raised piece 24 does not come out.

The side panel P1 and the toe panel P2 are assembled to the toe grip angle 11 and the side grip angle 21 as follows. First, the side panel P1 is greatly inclined outward with respect to the side grip angle 21 as shown in FIG. 6, and as shown by the alternate long and short dash line in FIG.
The lower frame 19 of the lower part 1 is inserted between the bent piece 23 and the cut-and-raised piece 24 of the side grip angle 21, and the side panel P1 is vertically erected from this state as shown by the solid line in FIG. As a result, the side panel P1 is prevented from coming out upward by the bent piece 23 of the side grip angle 21.

Similarly, the toe panel P2 is largely tilted outward with respect to the toe grip angle 11, and the lower frame 19 of the toe panel P2 is locked to the wedge-shaped portion 17 as shown in FIG. Raises panel P2 and lowers it 19
Is fitted between the vertical walls 15 and 16. As a result, the toe panel P2 is prevented from coming out upward by the wedge-shaped portion 17 of the toe grip angle 11.

It should be noted that the side portion P1a (P1b) of the side panel P1 and the side portion P2a of the toe panel P2 which are adjacent to each other.
(P2b) are engaged with each other as shown in FIG.

The other side panel P1 and the toe panel P
2 is also erected vertically below the waist 13 in the same procedure, and similarly, the side portion P1a and the side portion P2a, and the side portion P1b and the side portion P similarly.
2b are engaged with each other to form a cylindrical side wall.

[0012]

In the conventional steel transportation container C ', the distance L'between the lower end portion 17a of the wedge-shaped portion 17 of the toe grip angle 11 and the vertical wall 15 is narrowed, and the toe panel P2 is shown in FIG. 4 and FIG. 6, the lower frame 19 is slanted outward (θ2 = approximately 45 ° to 60 °) and the lower frame 19 is wedge-shaped portion 1.
I am trying to lock it at 7. The same applies to the side panel 1. For this reason, a wide space is required in the front, rear, left and right of the lower waist 13, and the steel transportation container C ′ cannot be assembled in a narrow space.

Further, since the panels P1 and P2 are mounted while being greatly inclined as described above, the line of sight of an operator leaning the panels is blocked by the panels P1 and P2, and the wedge-shaped portion 17 of the grip angle 11 and the grip angle 21 are bent. It was difficult to confirm the piece 23. Further, since the worker has to engage the lower frame 19 and the grip angles 11 and 21 while supporting the weight of the panels P1 and P2, the work efficiency is extremely poor.

In addition, as shown by the chain double-dashed line in FIG.
When the lower frame 19 of the toe panel P2 is once placed on the grip angle 11, the lower frame 19 is press-fitted between the wedge-shaped portion 17 and the vertical wall 15, and the left and right of the toe panel P2 with respect to the grip angle 11. In some cases, position adjustment in the direction (direction perpendicular to the paper surface of FIG. 4) becomes impossible.

The present invention has been proposed in view of the above circumstances, and an object thereof is to provide a steel transportation container which can be easily assembled and disassembled by slightly inclining the side wall panel to the outside. .

[0016]

In order to achieve the above-mentioned object, a grip angle for a steel transportation container according to the present invention has a side wall panel on each side of a lower waist upper surface edge which becomes a floor of the transportation container. In a steel transportation container which is erected and constitutes a side wall which is closed in a tubular shape by engaging side edges of the side wall panel with side edges of adjacent side wall panels, a lower edge of the side wall panel A horizontal plate-like lower frame fixed to the lower frame, and an engaged part integrally and horizontally extended from the outer side portion of the lower frame so as to slightly project from the outer surface of the side wall panel, An inner vertical wall extending vertically upward inside the lower edge of the side wall panel on the side of the lower waist upper edge, and on the side of the lower waist upper edge, An outer vertical wall extending vertically upward on the outer side of the lower edge of the side wall panel, A locking portion that extends integrally from the upper end of the outer vertical wall and hangs downward through the semi-arc-shaped bent portion on the side wall panel side and terminates at a position directly above the locked portion. The bent portion has a radius of curvature that vertically supports the side wall panel on a lateral side below the waist in the process of standing the side wall panel, and the lower end of the tip end of the locked portion of the side wall panel is The weight of the side wall panel is applied to the upper end surface and the weight is stored in the bent portion. When the side wall panel is tilted outward with the upper limit of about 10 ° in this state, the lower frame and the locked portion of the side wall panel are perpendicular to the inner side. A small radius of curvature that can be fitted between the wall and the outer vertical wall, the side wall panel is returned from the tilted posture to the vertical posture, and the locked portion is inserted under the locking portion. Is characterized by.

[0017]

In the state where the side wall panel is erected vertically on the lower side of the waist, the lower surface of the tip of the locked portion at the lower end of the side wall panel is brought into contact with the upper end surface of the bent portion of the lower waist outer vertical wall. Deposit the weight of in the bent part. In this state, the side wall panels and the lower waist are positioned in the left-right direction so that the side portions of the panel do not protrude from the lower waist corners. Since the contact area between the lower end surface of the locked portion and the upper end surface of the bent portion is extremely small, the frictional force is small and the operator can perform the positioning with a light force.

From this state, the side wall panel is moved outward by about 10 °.
The upper limit is tilted and the locked portion is slid along the locking portion between the inner vertical wall and the outer vertical wall. Next, the side wall panel is returned from the tilted posture to the original vertical posture with the tip of the locked portion abutting on the lower waist. As a result, the lower frame and the locked portion are fitted between the inner vertical wall and the outer vertical wall, and the locking portion is located right above the locked portion to prevent the side wall panel from coming off. The removal of the side wall panel is performed by reversing the above procedure.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described with reference to FIGS. The same components as those of the related art are denoted by the same reference numerals as those shown in FIGS. 4 to 7, and the description thereof will be omitted.

The steel transportation container C is constructed as a whole by arranging side panels P1 and toe panels P2 on four sides of the lower waist 13 in a standing manner. A lower frame 19 is attached to the lower end edges of the side panel P1 and the toe panel P2, and a locked portion 19a extending from the lower frame 19 has a side panel P1 and a toe panel P2.
It is slightly projected outward from the outer surface of the. In addition, a grip angle 1 for attaching the lower end edges of the side panel P1 and the toe panel P2 is attached to the lower waist 13.

The grip angle 1 includes a horizontal portion 4 on which the side panel P1 or the toe panel P2, to which the lower frame 19 is attached, and an inner vertical wall extending vertically upward at both ends of the horizontal portion 4. 5 and the outer vertical wall 6, a bent portion 7 extending from the upper end of the outer vertical wall 6 and formed in a semi-arcuate shape with a small curvature toward the inner vertical wall 5 side, and hangs vertically downward from the bent portion 7. The locking portion 8 is provided.

The width of the lower frame 19 including the engaged portion 19a is
It is configured to be slightly shorter than the width of the horizontal portion 4 of the grip angle 1. Further, the grip angle 1 has a locking portion 8
The distance L between the vertical wall 15 and the inner vertical wall 5 is the distance L ′ between the lower portion 17a of the wedge-shaped portion 17 and the vertical wall 15 and the bending piece 2
3 is wider than the distance L ″ between the upper end 23a of the No. 3 and the cut-and-raised piece 24. That is, when the side panel P1 or the toe panel P2 is inclined outward from the inner vertical wall 5 with an upper limit of about 10 °. , Lower frame 19 and locked portion 19a
The curvature of the bent portion 7 is set to be relatively small so that it can slide on the inner surface of the grip angle 1, in other words, the distance between the outer vertical wall 6 and the locking portion 8 is set to be relatively small.

Next, how to attach the side panel P1 or the toe panel P2 to the grip angle 1 will be described. First, as shown by the chain double-dashed line in FIG. 1, with the bottom surface of the lower frame 19 parallel to the horizontal portion 4 of the grip angle 1, the locked portion 19a is placed on the upper end surface 7a of the bent portion 7. At this time, the tip lower surface 19b of the locked portion 19a is in line contact with the upper end surface 7a of the bent portion 7. In this way, the lateral position of the side panel P1 or the toe panel P2 with respect to the grip angle 1 is adjusted with the total weight of the side panel P1 or the toe panel P2 stored in the bent portion 7. The sliding resistance of the lower frame 19 with respect to the upper end surface 7a of the bent portion 7 is low friction due to the line contact, and can move the side panel P1 or the toe panel P2 in the left-right direction with a small force.

Then, as shown in FIG. 2, the side panel P1 or the toe panel P2 is inclined outward. When the side panel P1 or the toe panel P2 is tilted from the inner vertical wall 5 of the grip angle 1 to the angle θ1, as shown by a dashed line in FIG. 1, the lower frame 19 and the locked portion 19a.
Is fitted between the inner vertical wall 5 and the outer vertical wall 6 of the grip angle 1. This angle θ1 is about 10 in this embodiment.
However, it is possible to carry out at an angle including 10 degrees or less, that is, less than 20 degrees.

The tip lower surface 19b of the locked portion 19a is shown in FIG.
As shown by the alternate long and short dash line, after coming into contact with the horizontal portion 4 of the grip angle 1, the toe panel P2 is vertically raised, and the vertical wall of the lower frame 19 is overlapped with the inner vertical wall. At this time, the tip lower surface 19b of the locked portion 19a comes into surface contact with the horizontal portion 4 of the grip angle 1 and is inserted below the locking portion 8, and the side wall panel P (the pair of side panels P1 and the toe panel P2) is inserted. And the engagement with the grip angle 1 are completed. The side portion P1
The a and the side portion P2a, and the side portion P1b and the side portion P2b have a structure similar to that of FIG. 7, and are engaged with each other in a tubular shape.

As described above, according to this embodiment,
When the lower ends of the panels P1 and P2 are vertically mounted on the grip angle 1, the sliding friction between them can be reduced, and when the panels are vertically set, the side panel P1 or the toe panel P2 and the grip are gripped. Since it is easy to visually confirm the engagement state with the angle 1, the position of the panel can be quickly adjusted. Further, since it is not necessary to incline the side panel P1 or the toe panel P2 to the outside, the panels P1 and P2 can be efficiently and surely assembled to the grip angle 1 even in a narrow place.

When disassembling the steel transportation container, the procedure reverse to the above procedure, that is, the side panel P1 or the toe panel P2 is tilted outward by about 10 °, and the side panel P1 is removed.
Alternatively, by lifting the toe panel P2 above the grip angle 1, the side panel P1 or the toe panel P2 can be easily pulled out without damaging the locking portion 8, and the steel transport container C can be reused. It becomes possible.

The grip angle 2 shown in FIG. 3 (a) is
A bent portion 7'having a U-shaped cross section is extended from the upper end of the outer vertical wall 6 toward the inner vertical wall 5.

The grip angle 3 shown in FIG. 3 (b) is
A panel gripping portion 9 is formed in the middle of the outer vertical wall 6 so as to bulge in a semi-arc shape toward the inner vertical wall 5.

Grip angle 10 shown in FIG. 3 (c)
Is formed by cutting and raising 10a toward the inner vertical wall 5 in the middle portion of the outer vertical wall 6.

These grip angles 2, 3 and 10 can also be suitably used for inclining and engaging the respective panels P1 and P2 at a small angle of about 10 °.

[0032]

As described above, according to the steel transportation container of the present invention, when the side wall panel is temporarily placed under the waist,
Sliding friction between them can be reduced. Further, since the side wall panel is temporarily placed vertically, an operator who manually supports the side wall panel can see through the lower end portion of the side wall panel satisfactorily, and the position of each panel in the left-right direction can be easily adjusted.
Also, by widening the gap between the locking part and the inner vertical wall, making the bent part have a small curvature, and narrowing the space between the locking part and the outer vertical wall, the locked part can be tilted slightly outward. Since it can be easily slid into the locking portion and can be removed, it is possible to assemble or disassemble even in a narrow space where space is not enough.
