Description Steel transport container Technical field

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple assembly type steel plate transport container used for transporting automobile parts and the like.

In a transport container used to transport automobile parts and other goods and used for export, etc., it is made of a steel plate that safely and securely protects the stored goods, and is an easily assembled type that is relatively easy to assemble and disassemble. There is something. For example, Japanese Utility Model Application No. 61-72761 (Japanese Utility Model Application Laid-Open No. 62-185295), Japanese Utility Model Application No. 61-139751 (Japanese Utility Model Application No. 63-46329), and Japanese Patent Application No. 2-270449, etc. Examples of such prefabricated steel shipping containers are disclosed. This simple assembling steel sheet transport container has a square tubular side wall formed by erecting a square panel on four peripheral edges of a square floor member. The side wall of the transport container is usually one in which a number of columns, beams, and beams are attached vertically, horizontally, and diagonally to the inner surface of a panel made of a flat iron plate, etc. Coupling is performed with bolts and evening screws.

Among the many features of these prefabricated steel transport containers, the most outstanding point is that, first, the four walls of the box, that is, two glue panels and two toe panels, are made of corrugated steel. This makes it possible to make containers that are lightweight and stiffer. Second, they do not use nails, bolts, screws, etc. to stand these panels on the container floor structure (bed). All that is required is to simply fit the lower panel of the panel into the grip members (grip angles) provided especially around the four sides of the platform to make the panel stand upright, so that the container assembly work is not only extremely easy and quick, but also disassembled. The work is quick and easy and ffi: perfect for use.

The side wall panel that stands in the direction along the pedestal is called the gawa panel, and the side wall panel that stands in the direction that intersects with the pedestal, that is, the direction in which the forklift's claws, etc. enter, is pinched. It is called le.

According to the above-mentioned transport container, since a large number of columns and crossbars are attached to the inner surface of the panel constituting the side wall, the number of components increases, the total weight of the transport container increases, and the container itself becomes expensive, As a result, there has been a problem that the cost of transporting articles is high. In addition, there are many man-hours for assembling the floor members and the side walls of the shipping container, and disassembling the assembled shipping container, and special tools are required for assembling and dismantling the container.

Assembling and dismantling one shipping container took a lot of time.

The grip angle, which is one of the features of the assembled steel transport container, is proposed by the present applicant and is provided along the four sides of the bed of the assembled steel transport container. Conventionally, grip angles for glue panels have typically been manufactured in a shape as shown in FIG.

That is, a grip portion (203) having an outer surface of a long plate-like flat portion (202) and a grip angle (201) having a panel receiving wall (204) on the inner side are firstly connected to a support of a pedestal. Spot welding is performed on the upper surface of a strip-shaped cover plate (206) having a width sufficient to cover the upper opening of the base (205).

Next, one flange (205a) of the pedestal (205) is inserted into the folded portion (207) at the front edge of the lid plate (206), and the flat portion (206a) of the lid plate (206) is attached to the pedestal. The other flange (205b) of (205) is spot-welded to join the pedestal (205) and the cover plate (206) to form the glue portion of the pedestal. Then, as shown in FIG. 10, between the grip portion (203) of the grip angle (201) fixed to the upper surface of the pedestal (205) via the lid plate (206) and the panel receiving wall (204). The ridge (21 1a) of the lower sill (21 1) of the glue panel (210) is fitted to support the glue panel (210). Disclosure of the invention

When the grip angle (201) supporting the glue panel (210) is formed as described above, when the grip angle (201) is fixed to the pedestal (205), the grip angle (201) is connected to the lid plate (206). After the spot welding, the lid plate (206) must be fixed to the pedestal (205).

L In addition to the problem that it leads to a rise, the lid plate (206) and the grip angle (201) are fixed on the upper surface of the pedestal (205) to form the base of the base. Then, there is a problem that the weight of this part also increases, and there is still room for improvement in such a conventional method from the viewpoint of saving materials, reducing the number of manufacturing steps, and reducing the weight of the entire container. Was.

An object of the present invention is to provide a simple assembling type steel sheet transport container which is lightweight, inexpensive, robust, and can be easily assembled and disassembled by an amateur without using tools. It is in.

The present invention relates to a transport container in which a panel is erected on the periphery of a rectangular floor member having a sliding material on a bottom surface, and both sides of each orthogonal panel are joined to each other to form a rectangular side wall. In order to achieve the above, a grip metal fitting having a bent portion bent inwardly of the floor member is fixed to the periphery of the floor member, and the lower portion of each panel is removably fitted to the bent portion of the grip metal. The stile is fixed, the panel is raised on the periphery of the floor member by fitting the grip bracket and the lower stile, and the ends of the panel that is orthogonal to and adjacent to this panel are fitted to at least both ends of the opposing panel. The hollow-structured columns that are removably inserted are attached together, and the orthogonal ends of the upright panels are connected via the columns.

The above-mentioned panels are mainly made of corrugated steel plates, or have only hollow columns and frames. In addition, various reinforcing members are applied between the floor member and the panel or between the panels according to the use of the transport container.

To raise panels on the four peripheral edges of a square floor member, insert the lower gussets of the corresponding panels into the bent parts of the two peripheral rims of the floor member, and raise the two panels. Then, fit the lower stile of the corresponding panel into the bent part of the grip metal fittings on the other two peripheral edges of the floor member, erect the remaining two panels, and join the adjacent panels via pillars This makes it possible to assemble the shipping container easily and quickly without using tools. In addition, disassembly of the transport container can be performed easily and in a short time without using any tools by performing the reverse operation of assembly.

In addition, since the pillars at the corners of the panels that are orthogonally adjacent to each other are made of a hollow steel plate having a fitting structure, the panels can be easily joined, and the strength of the corners between the panels can be reduced. It becomes much easier to stack transport containers. BRIEF DESCRIPTION OF THE FIGURES

Hereinafter, various embodiments of the transport container according to the present invention will be described with reference to the drawings.

A prefabricated steel transport container with an improved grip angle will be described with reference to FIGS.

As shown in Fig. 1, the assembled steel transport container consists of a pair of glue panels (220A) (220B) and a toe panel (220B) on a pedestal (215) with multiple pedestals (216). 2 Raise the 21A) and (221B), and join the two sides of the Katsuga panel (220A) and (220B) with the toe panels (221A) and (221B) to form a side wall. Attach the corner bracket (222) to the section, and install the panel (22 OA) (220 B) Beam (223) is installed between them.

As shown in FIGS. 2 to 4, the pedestal (215) is composed of a plurality of pedestals (216), three in the illustrated example, arranged at intervals, and a toe panel ( 221 A) (221 B) For supporting, after bridging a grip angle (201) with a grip part (203) formed on the outer periphery of the flat part (202) and a panel receiving wall (204) inside, as in the past. The improved grip angle (225) according to the present invention is fixed on the pedestal (216) located on the outer side for supporting the panel (22 OA) (22 OB). It is constructed by stretching a floor plate (224) made of steel plate or the like.

The improved grip angle (225) should be wide enough to cover the width of the outer flange (216a) and inner flange (216b) of each outer pedestal (216), as shown in Figures 2 and 3. On the front edge of a single strip-shaped support plate (226), downwardly bent portions (227) are formed at predetermined intervals, and several upwardly bent portions (230) are formed therebetween.

The upwardly bent portion (230) serves as a grip for gripping the protruding edge (233a) of the lower sill (233) of the girder panel (22 OA) (220B). It is formed at an acute angle directly to the plane part (226a) and inclined inward and upward.

Several panel receiving walls (231) are cut and raised upright from the upward bent portion (230).

With the improved grip angle (225), to form the girder of the pedestal (215), a downward bent part (227), an upward bent part (230) and a cut-and-raised panel receiving wall (231) are formed. The support plate (226) is connected directly to the pedestal (216).

That is, insert the outer flange (216a) of the pedestal (216) into the downwardly bent part (227) as shown by the broken line, and attach the inner flange (216b) to the inside of the flat part of the support plate (226). By connecting to the rim, the improved grip angle (225) and the pedestal (216) are integrated to form the base of the floor.

If the base of the bed (215) is formed as described above, (226) can be formed only with the improved grip angle (225) and the pedestal (216), eliminating the need for the lid plate (26) as in the past, reducing the number of parts and reducing manufacturing costs. The process can be simplified.

A cut-out hole (232) is formed in the rear part of the flat part (226a) of the support plate (226) by cutting and raising the panel receiving wall (231), so that the weight is reduced by that amount, and Since the number of parts has been reduced, the weight of the glue can be reduced. The panel (22 OA) (220 B) standing upright on the pedestal (215) formed as described above may be the same as the conventional one, with the lower stile (233) and the upper stile (234). )), A corrugated steel plate (235) is stretched between them, and a side column (236) with a U-shaped cross section is connected to both sides. The corrugated steel plate (235) consists of a series of peaks and valleys. In addition, the toe panels (221 A) and (221 B) are

It has a structure similar to that of 20 B). A corrugated steel plate (240) is stretched between the lower stile (237) and the upper stile (238), and U-shaped side columns (241) are connected to both sides. The corrugated steel plate (240) consists of a series of peaks and valleys. The dimensions of the side columns (241) of the toe panels (221A) and (221B) are

(236) are formed in dimensions and shapes to hold

Then, in order to form the assemblable steel transport container by erecting the glue panels (220 A) (220 B) and the tongue panels (221 A) (221 B) on the bed (215), first, Upward bent part (2) of improved grip angle (225) of pedestal (215)

Fold the lower stile (233) of the glue panel (22 OA) (22 OB) slightly outward between the 30) and the cut-and-raised panel receiving wall (231), and insert it into the upward bent part (230). After inserting the protruding edge (233a) of the lower stile (233), the upright panel (220A) (220B) is erected and the straight wall (233b) of the lower stile (233) is inserted. Is pressed against the panel receiving wall (231), and the glue panel (22 OA) (22 OB) is stably upright.

The glue panels (22 OA) (220 B) are erected on the bed (215) facing each other, and then they close both the glue panels (22 OA) (22 OB). Tongue panels (221 A) and (221 B) are erected in pairs.

The tongue panels (221 A) and (221 B) are also tilted slightly outside at first, Insert the gusset (237) under the grip (203) of the grip angle (201), and then stand it upright. Then, the side columns (241) of the toe panels (221A) and (221B) are connected to the glue panel. (220 A) Engage the outside of the side column (236) of (220 B).

As a result, four panels are erected in a box shape on the four sides of the bed (215), and side pillars with a square cross section are formed at the four corners of the box.

After that, corner fittings (222) are attached to the corners of the glue panel (22 OA) (220 B) and the toe panels (221 A) (22 IB), and the glue panel (22 OA) (22 Cover the beam (223) between OB) and complete the shipping container.

In addition, in the above embodiment, the upwardly bent portion (230) is formed at an acute angle with respect to the plane portion (226a) of the support plate (226), and is directly inwardly inclined upward as shown in FIG. As shown in the figure, one end may be bent upward at a substantially right angle from the flat part (226a), and then bent inward near the upper edge.

Although the grip (203) of the grip angle (201) on the toe side is illustrated as having a continuous length, the grip (203) may be cut off at predetermined intervals as appropriate to form an intermittent structure. Instead of the conventional grip portion (203) bent downward, a grip portion may be formed, as shown in FIG. 6, that is inclined directly inward at an acute angle with respect to the flat portion (202).

In the improved grip angle (225), even if the glue panel (22 OA) (220 B) is standing, water or the like may enter the container at the part (244) where the panel receiving wall (231) has been cut off. May occur. Therefore, when high waterproofness is required, as shown in FIGS. 7 and 8, the flat part (226a) of the support plate (226) is bent upward to form a panel receiving wall having a saw-toothed cross section. (245) is formed over the entire length to form an improved grip angle (246). The panel receiving wall (245) makes the upwardly bent portion (230) a vertical plane.

In the above-mentioned improved grip angle (246), even if water enters from between the lower stile (233) of the standing upholstered panels (22 OA) and (22 OB), the panel receiving wall of the improved grip angle (246) can be used. Infiltration is prevented at (245) and does not enter the container. Also, the panel receiving wall (245) is formed over the entire length, and Since it has a cross section of a shape, the bending strength is increased, and it can be used not only on the glue side but also on the toe side.

According to the present invention, an improved grip angle can be formed by processing the front edge of one support plate into a downwardly bent portion and an upwardly bent portion, and cutting and erecting the panel receiving wall from a flat portion to erect the same. By constructing a bed using this improved grip angle, it is possible to reduce the amount of materials, reduce the number of manufacturing steps, and reduce the weight of transport containers compared to conventional prefabricated steel transport containers. Can be achieved.

Further, when the panel receiving wall of the improved grip angle is formed in a saw blade shape, it is possible to prevent water and the like from infiltrating and to provide a water-resistant assembled steel transport container.

Corners between adjacent panels are reinforced by corner fittings 30 described below. The corner fitting 30 has, for example, a structure as shown in FIG. 11, and forms a side wall 32 by bending the oblique side of the triangular upper wall 31 at right angles downward, and cuts a part of the side wall 32 to form a lower side. A locking piece 33 is formed to extend to the side. At a part of the right angle corner of the upper wall 31, a projection 34 for regulating the container position, which will be described later, is formed. On the inner surface of the side wall 32, a projection 35 is formed which is engaged with the outer lower end of the upper stile 13 of the panel 10. .

The corner fitting 30 is put on a part of the corner of the adjacent panel 10 from directly above, and the locking piece 33 is inserted into the slit 26 of the stile 13 on the adjacent panel 10. When the upper wall 31 of the corner fitting 30 is seated on the upper stile 13, the projection 35 of the side wall 32 is locked to the lower edge of the upper stitch 13, thereby preventing the corner fitting 30 from coming off. The corner fitting 30 prevents separation of the orthogonally adjacent glue panel 10s and the toe panel 10e, and reinforces the orthogonal corners. Next, a modified example of the dalib fitting and a modified example of the fitting structure of the columns will be described with reference to FIGS. As shown in FIGS. 12 and 13, the grip fitting 3 a extends in the same cross section along the four sides of the floor member 1, and has a vertical straight wall 5 a that supports the lower end inner surface of the panel 10 e. It has a horizontal bottom wall 6a and a bent portion 7a bent in an inverted V-shape. The base end of the bent portion 7a extends vertically upward from the outer end of the bottom wall 6a, and the tip end of the bent portion | a extends obliquely downward inward of the floor member 1. ing. In the grip metal 3a, the base end of the bent portion 7a extends vertically, and this portion can increase the bending rigidity of the grip metal 3a in the vertical direction and, consequently, the bending rigidity of the floor member 1. To set the panels 10 e and 10 s on the four sides of the floor member 1, as in the above-described embodiment, Then, as shown by the dotted line in Fig. 13, the panel 10e.10s is inclined and its lower end is placed on the bottom wall 6a of the grip bracket 3a. Raise it in the direction of the arrow to make it vertical. As a result, the lower end of the lower surface 22 protruding outward in the horizontal direction at the lower ends of the panels 10 e and 10 s fits inside the bent portion 7 a, and the lower ends of the panels 10 e and 10 s are joined to the floor member 1. Is done.

Figs. 14 (A) and (B) show a modified example of the strut fitting structure. The struts 14a and 15a fixed to the ends of the panels 10e and 10s are both U-shaped in cross section. The struts 14a and 15a are made into an integrated common strut with a hollow square pipe by mating the struts a and 15a from the condition shown in Fig. 14 (A) to the condition shown in (B). Things. This results in a so-called closed structure in which the periphery of the column is closed, and its strength can be increased. The pillars 14a and 15a have a projection 24a on one side and a hole 25a on the other. The necessary number of the combinations of the projections 24a and the holes 25a are provided in the vertical direction of the columns 14a and 15a. By fitting the projection 24a into the hole 25a, the integral structure of the columns 14a and 15a is strengthened, and the columns 14a and 15a are prevented from being easily separated.

Next, a modified example of the corner fitting 30 will be described with reference to FIGS. No particular measures were taken to reinforce the upper wall 31 in the corner fitting 30 in Fig. 11 described above, but if strength is required, as in the corner fittings 30 in Figs. Form a concave rib 95 for reinforcement. As a result, even if the transport containers are stacked and used, the corner fittings are not deformed, and the distortion of the transport containers can be suppressed. Further, in order to strengthen the engagement force of the corner fitting 30 with the upper stile 13, another projection% besides the projection 35 is formed on the inner surface of the side wall 32 as shown in FIG. A projection 99 is formed on the outer surface of the substrate. These retaining structures may be employed alone, or a plurality of retaining structures may be employed in combination.

Next, still another steel sheet transport container will be described with reference to FIGS. This transport container is a steel plate transport container of the type consisting of standing up a panel made of steel plate around the lower part of the waist where the bottom wall member is mounted on the pedestal, and connecting the bottom wall member to the panel and the panels.

The tongue panels (326A) and (326B) have the same structure as the conventional one, with the L-shaped lower stile (326b) attached to the lower end of the corrugated panel (326a) and the 钩 -shaped upper end at the upper end. A stile (326c) is installed, and U-shaped columns (326d) (326d) are installed on both sides. In addition, this support (326d) (326d) has a slit through which the locking piece (325e) formed on the support (325d) (325d) of the side panel (325A) (325B) penetrates. (326e). However, the side panels (325 A) (325 B) are longer than the toe panels (326 A) (326 B).

The two-end lubricating material (324A) (324B) has the same structure, and one of them can be described as shown in Figs. 19 and 20. ) Is bent obliquely downward at an appropriate height to form a retaining piece (331) integrally. The other end of the rising part is bent outward to form a horizontal flange (330b). The width of both ends of the retaining piece (331) is slightly shorter than the distance between the columns (325d) and (325d) of the side panel (325A). As shown in Fig. 23, when the side panel (325A) is assembled, a gap (332) is created between the retaining piece (331) and the column (325d). This is the side panel

This is to make it easier to fit the lower stile (325b) into the retaining piece (331) when erecting the (325A), so that a gap of about 2 to 3 millimeters is set.

With the side panel (325A) slightly inclined outward, as shown in Figs. 21 and 24, the lower stake (325b) is attached to the channel steel (330) that constitutes the sliding material (324A) at both ends. Insert it into the riser (330a) and the other riser, sit down, raise it, and fit the lower stile (325b) into the retaining piece (331). Next, the other side panel (325 B) is similarly set up on both ends of the sliding material (324 B). Next, as shown in Fig. 22 and Fig. 23, with the toe panel (326B) slightly inclined outward, the lower stake (326b) is attached to the toe of the waist (322) at the toe edge. Insert it into the grip fitting (333), raise it after sitting down, pull out the lower stile (326b) and fit it into the retaining piece (334). And when standing up, the support of the toe panel (326 A)

(326 d) is fitted to the support (325 d) (325 d) of the side panel (325 A) (325 B), and the locking piece (325 e) is fitted to the slit (326 e). Next, raise the toe panel (326 B) in the same manner and set up the side panel (325 A)

(325 B). Finally, as shown in Fig. 25, a corner fitting (335) is put on the corner of the side panel (325A) and the toe panel (326A), and a projection piece formed at the intersection of the corner fitting (335) is formed. 335a) (335b) with the upper stile (325c) and toe panel (326A) on the side panels (325A) (325B)

It is inserted into the locking holes (325f) (326f) formed in the upper stile (326c) of (326B). Finally, attach the beam (336) between the side panels (325 A) and (325 B) to complete the assembly.

In the assembled transport container, when the side panel (325A) is displaced in the direction of the arrow shown in Fig. 21, the strut (325d) hits the retaining piece (331) of the sliding material at both ends (324A), No deviation. In addition, since the columns (325 d) of the side panels (325 A) and (325 B) and the columns (326 d) of the toe panels (326A) and (326 B) are fitted to each other, the columns become square pipes. Becomes stronger. And the side /

(325 A) (325 B) stand on both ends (324 A) (324 B) The sliding material at both ends (324 A) (324 B) is not crushed, and the pressure resistance is very high. The locking piece (325e) provided on the column (325d) of the side panel (325A) (325B) and the slit provided on the column (326d) of the toe panel (326A) (326B). Combination with (326 e) does not cause any vertical displacement.

The sliding material at both ends (324 A) and (324 B) forms not only the retaining piece (331) continuously but also a plurality of short retaining pieces (340) intermittently as shown in Fig. 26. It may be formed.

Also, as shown in FIGS. 18 and 25, the corner fitting (335) is provided with a projection (337) for preventing a displacement of the upper transport container when the transport containers are stacked. On the other hand, as shown in Fig. 27, by forming positioning holes (341) into which the protrusions (337) enter, as shown in Fig. 27, the transport container can be made When stacked, the protrusions (337) of the corner fittings (335) attached to the lower transport container were formed on both ends of the upper transport container (324A) (324B) as shown in Figure 28 It does not enter the positioning hole (341) and cause no misalignment during transport. Alternatively, as shown in FIG. 29, the retaining piece (342) of the sliding material (324A) (324B) at both ends may be formed by directly bending inward from the bottom edge. In this case as well, the retaining piece may be formed as a retaining piece (342) that is continuous in the longitudinal direction as shown in FIG. 30, or a short retaining piece (343) may be intermittently provided as shown in FIG. A plurality may be formed.

Alternatively, as shown in FIG. 32, a retaining piece (344) may be formed by bending the upper end of the rising portion of the sliding material (324A) (324B) at both ends horizontally from the upper end. In this case, bend the edge of the lower stile (325b) of the side panel (325A) upward.

In addition, the sliding material at both ends (324A) of the transport container is subjected to external force from the side by means of forklift claws, etc., and the grooved steel material (330) of the sliding materials at both ends (324A) (324B) is shown in Fig. 33. When deformed as shown by the two-dot chain line, the lower stile (325b) of the lower end of the corrugated panel (325a) comes off from the retaining piece (331) of the sliding material (324A) (32413) at both ends, and the side panel (325 If there is a possibility that A) may fall upward, as shown in the solid line in Fig. 33 and Fig. 34, the sliding material at both ends (324A) (324B) A slip prevention piece (350) is formed. In this way, even if external force is applied from the side, the slip prevention piece (350) hits the lower stake (325b) of the side panel (325A) (325B), The side panels (325 A) and (325 B) prevent deformation of the channel steel (330) of both ends of the sliding material (324 A) and (324 B). The side panels (325A) and (325B) do not fall out because the 324A) and (324B) do not deform as shown by the two-dot chain line in FIG.

According to the present invention, since the lower end of the side panel is supported by the sliding members at both ends below the waist, the vertical load is directly transmitted to the bottom surface of the sliding members at both ends via the side panel, and the sliding members at both ends are crushed. As a result, the pressure resistance of the entire transport container is improved.

In addition, the sliding material at both ends can be composed of a single channel steel material, which makes it possible to reduce the weight of the transport container, facilitates production, and reduces the number of parts to reduce material and production costs.

Also, in the case where the slip prevention piece is formed, even if an external force acts on the slide material at both ends from the side, the side panel is pressed by the slip prevention piece and the slide material at both ends is prevented from opening. There is no departure and the safety is very high.

According to the present invention, each panel is erected on the four peripheral edges of the square floor member by the fitting and locking structure of the grip fitting and the lower stile, and the ends of the orthogonally adjacent panels are fitted to each other. Since the transport container can be assembled and the container can be disassembled in the reverse order, it is possible to provide a transport container that can be assembled and disassembled without the use of tools and that can be easily and quickly performed by an amateur.

In addition, the corners of the rectangular cylindrical side wall composed of panels are made of hollow steel pillars, and the corners are reinforced with corner fittings, further increasing the vertical strength of the corners. In addition, it is possible to provide a transport container that can be stably stacked with a stable strength by eliminating the occurrence of twisting at a part of a corner.

Further, when the corner fitting is attached to a part of a butt corner of each of the upper stiles of the first panel and the second panel, a locking portion provided on the corner fitting is attached to the first panel and the second panel. Since it fits into the slits provided in each upper stile of the panel to prevent misalignment, the first panel and the second panel can be more securely joined, and a highly rigid transport container can be constructed. . Also, when the corner fittings are formed with ribs for preventing deformation, even if the transport containers are stacked and used, the corner fittings are not deformed and the distortion of the transport containers can be suppressed. Furthermore, when the corner fitting is formed with an engaging portion or a projection that engages with the upper stiles of the first panel and the second panel, the corner fitting does not come off accidentally, thereby improving safety.
