Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cargo box structure of a freight vehicle such as a dry truck or a temperature control vehicle. More specifically, the present invention relates to a panel of a side wall (front panel) and a front wall (front panel) of each cargo box. It is related with the packing box structure comprised so that attachment / detachment exchange was possible easily.
[0002]
[Prior art]
6 is a perspective view showing an example of a freight car provided with a cargo box, and FIG. 7 is a vertical sectional view corresponding to the line AA in FIG. FIG. 8 is a vertical sectional view corresponding to the AA line portion in FIG. 6 showing a packing box structure in a conventional temperature control vehicle. In the case of the dryn shown in FIG. 7, a panel structure in which a thin outer plate such as a metal corrugated plate is fixed by a large number of rivets to a plurality of posts erected at intervals on the side of the packing box is common. Such a lower end portion of the side panel SP is fastened and fixed with a bolt or the like via a lower rail LR to a lower frame member UW extending to the end of the lateral joist N on the chassis of the truck. Therefore, when it is necessary to replace the side panel SP or the outer plate due to damage or the like, it is complicated to remove a large number of rivets that fasten and fix the outer plate, the post, and the lower rail LR, If it is necessary to replace the lower rail LR at the same time, the floor panel YP is bonded and fixed on the lower rail LR. Therefore, the joint portion S between the two members is peeled off and the lower rail LR is pulled out of the cargo box. There was a disadvantage that had to be done. Such a situation was the same in the case of the temperature management vehicle shown in FIG. 8 in which the thick plate-like side panel SP filled with the heat insulating material was used.
[0003]
Even if the side panel SP is damaged and needs to be replaced or repaired, there may be no problem with the lower rail LR itself, but the lower rail LR adhered and fixed to the side panel SP, post, floor panel YP, etc. Since it will be damaged when removing, it will be forced to replace. In addition, the work for removing the interior material of the packing box and the floor panel YP is necessary at the time of removing the lower rail LR, which is complicated. Furthermore, when the lower rail LR is pulled out by peeling the adhesive surface S between the lower rail LR and the floor panel YP, a new lower rail LR is forcibly inserted between the floor panel YP and the lateral joist N. As a result of adhesion failure without spreading, waterproofing measures are insufficient, and there is a risk of causing a water leak accident or the like.
[0004]
However, as disclosed in, for example, Utility Model Registration No. 3051592, a packing box structure in which each wall surface of the packing box including the side panel is made into a panel is also proposed, but it is also extended from the lower frame of the side panel. Since the floor panel is placed and fixed on the horizontal plate, the floor panel has to be removed when replacing a damaged or soiled side panel, which is cumbersome.
[0005]
Further, in the conventional cargo box, the same structure as that of the side panel SP is adopted for the front panel located on the cabin side. However, since the space between the front panel and the cabin is extremely narrow, the cargo box is once mounted on the cargo vehicle. After installing, the work space for rivet driving tools etc. will be insufficient, and it will be extremely difficult to replace the front panel skin and the front panel itself. The separated box was lifted with a crane and removed.
[0006]
[Problems to be solved by the invention]
In order to increase the operation rate of a freight vehicle that contributes to transportation operations, it is necessary to quickly replace and repair damaged side panels and front panels, and it is desirable to reduce the cost required for replacement and repair as much as possible. As mentioned above, paneling each wall of the packing box has been done in the past, but these are intended to improve workability when assembling the packing box exclusively, improving workability during repair and replacement In order to achieve this, no packing box structure has been found that can be easily attached and detached for each side panel or front panel. The present invention is intended to solve these problems, and it is an object of the present invention to provide a packing box structure that can realize quick and low-cost repair / replacement work.
[0007]
[Means for Solving the Problems]
In order to solve the above-described problem, in the cargo box structure according to the present invention, in the cargo box that is configured by connecting the peripheral portions of the substantially flat panel members to each other, the upper of the side panel is provided. The lower frame member is fixed to the horizontal joist of a lorry by projecting connecting arms extending in the vertical direction of the panel on the rail and lower rail, and connecting arms extending in the horizontal direction of the panel on the left and right side rails of the ceiling panel. On the upper side, connecting arms extending upward are projected so as to connect the corresponding connecting arms in the upper rail of the side panel and the side rail of the ceiling panel, respectively, while corresponding in the lower rail of the side panel and the lower frame member, respectively. The packing box is configured by connecting the connecting arms together. Therefore, if the connection between the coupling arms is released, only one side panel including the lower rail can be removed from the packing box without disassembling the packing box.
[0008]
next,in frontThe upper rail and lower rail of the side panel in the packing box structure are integrally formed of a metal mold with a connecting arm projecting on the opposite side of the receiving portion as a frame with a receiving portion having a substantially U-shaped cross section. In addition, the connecting arm connecting portions of the side panel and the ceiling panel and the connecting arm connecting portions of the side panel and the lower frame are respectively fastened from the outside of the packing box, and a load is applied to each of the fastening portions. Configured to attach a decorative cover from the outside of the boxby doingThe rivets need not be fixed, and the upper rail and the side panel main body and the lower rail and the side panel main body can be fixed to each other only by sandwiching the edge of the side panel by the receiving portion. It is desirable to make the decorative cover detachable by a fitting method, etc. However, even if the joint part with the ceiling panel or lower frame member is adhesively fixed with a sealing agent etc., the adhesive part is separated by a cutter or other blade If cut, the detachability of the side panel is not impaired.
[0009]
And between the receiving part of the upper rail and lower rail in the side panel of the above-mentioned packing box structure is formed wider than the thickness of the side panel body edge, and the sealant reservoir groove is provided on the inner surface of one receiving part In addition, while forming an inclined surface closer to the bottom than the position corresponding to the seal pool groove on the inner surface of the other receiving portion, the receiving portion bottom side has the same width as the side panel body edge portion, and the inside of the receiving portion of the panel body After being inserted into the spacer, a spacer is inserted into the receiving portion side having an inclined surface so that the panel body is sandwiched by the receiving portion.
[0010]
When mounting each rail to the panel body edge, a sealant is applied to the inner surface of the rail receiving part to adhere and fix both, but the panel body edge fits straight into the receiving part. When inserted, the adhesive applied in the receiving part is scraped off by the end face of the panel edge, and there is a disadvantage that it does not spread between the panel main body edge and the receiving part. Therefore, in the present invention, when the receiving portion is formed wide and the edge of the panel body is fitted along the inclined surface of the one side receiving portion, the sealing agent reservoir groove on the inner surface of the other side receiving portion is filled. It was formed so that the side surface of the panel main body edge was pressed and adhered to the sealing agent.
[0011]
Furthermore, in addition to the upper rail and the lower rail in the side panel, the front rail and the rear rail are each formed as a frame having a receiving portion having a substantially U-shaped cross section, and the receiving portion located outside the side panel is opposite to the receiving portion. The joint arm is integrally formed as a metal mold member with a joint arm projecting to bend to the inside of the side panel, and each joint arm projects to a joint position corresponding to the side panel on the front post and the rear post. On the other hand, if the fastening work is performed from the inside of each packing box and a makeup cover is attached to each fastening part from the inside of the packing box, one worker sequentially applies to each panel fastening part. It is possible to work, and one person outside the packing box and one person inside the packing box, a total of two workers share the work inside and outside the packing box in a balanced manner. Quickly so it is also possible to perform replacement of the side panels while.
[0012]
In the invention described in claim 2, the same packing box structure as that of the side panel in claim 1 is applied to the front panel. That is, in a cargo box configured by connecting peripheral edges of substantially flat panel members to each other, connecting arms extending in the vertical direction of the panel are respectively provided on the upper rail and the lower rail of the front panel to project the ceiling panel. The front rail is provided with a connecting arm extending in the horizontal direction of the panel, and a connecting arm extending in the upward direction is provided on the lower frame member so as to correspond to each other in the upper rail of the front panel and the front rail of the ceiling panel. While connecting the arms, it was decided to configure the packing box by connecting the corresponding connecting arms to each other in the lower rail and the lower frame member of the front panel. The rivet is not required to be removed, and only the front panel including the lower rail can be removed from the cargo box without disassembling the cargo box simply by releasing the connection between the connecting arms.
[0013]
In addition, the upper rail and the lower rail of the front panel in the packing box structure are each made into a frame body having a receiving portion having a substantially U-shaped cross section, and integrally with a metal mold member with a connecting arm protruding on the opposite side of the receiving portion. Forming and connecting the connecting arm connecting portions of the front panel and the ceiling panel and the connecting arm connecting portions of the front panel and the lower frame from the outside of the packing box, respectively. While mounting the decorative cover from the outside of the box, the space between the receiving portions is formed wider than the thickness of the edge of the front panel main body, and a sealant reservoir groove is provided on the inner surface of one receiving portion, and the other receiving portion The bottom surface of the receiving portion is the same width as the edge of the front panel body while forming an inclined surface closer to the bottom than the position corresponding to the seal pool groove on the inner surface of the panel. It was formed so as to sandwich the panel body by a receiving portion spacer is inserted into the receiving portion having an inclined surface on after being fitted into the portion receiving the body edge.
