[Industrial applications]

 The present invention relates to a corrugated block used for assembling a truck body.

[0002]

[Prior Art]

 Until now, as a body of a large truck, a structure in which a plurality of intermediate support pillars are provided on the loading platform and a corrugated aluminum plate having a thickness of about 0.6 mm as an outer wall plate is fixed to the intermediate support pillar with rivets is widely used. However, in the case of a truck body having such a corrugated aluminum plate attached, there is a problem that intermediate struts must be provided at a plurality of places on the cargo bed during assembly. .. Moreover, when attaching the corrugated aluminum plate to the intermediate column, it is necessary to use a large number of rivets, so that the assembly work takes a lot of time. Also, in the case of a body with such a structure, sufficient strength cannot be obtained by simply attaching a corrugated aluminum plate, and interior work is done by applying a veneer plate or a slat board to the inside of the body. It is necessary to perform this separately, and many processes are required, resulting in extremely poor productivity. Further, in many conventional wing bodies, in order to increase the strength in the longitudinal direction of the body, it is necessary to provide a column at the central portion in the longitudinal direction of the body.

Therefore, recently, it has been practiced to assemble the track bodies by joining the aluminum elongated blocks to each other and then fixing them with rivets or the like. Some have joints protruding parallel to the block surface at both ends. However, in the case of such a block, since the adjacent joints are stacked parallel to the block surface and rivets are driven and fixed in this part, the load in the direction perpendicular to the block surface is strong, but Very weak against parallel loads. Therefore, when manufacturing a trek body using such a kit-type block, a large number of rivets must be used for joining in order to obtain sufficient strength.

In addition, there is a recent truck body in which a "lashing rail" for attaching a luggage fixing belt called a "lashing belt" used for preventing load collapse is installed. Until now, lashing rails were installed directly on the intermediate columns, or after the interior construction was installed between the plywood boards and the slatted boards. However, in the track body having such a structure, the lashing rail projects to the inner side of the track body, and since the mounting is done only at the intermediate support, the lashing rail itself must be strong. There is.

Further, in some recent trucks, a heat insulating material is arranged on the inner wall surface of the body in order to reduce the temperature change inside the body. In this case, however, the heat insulating material is provided inside the track body with a gap. Since it is pasted without any and then poly-plywood or FRP plywood is pasted on it, the work takes time and the cost becomes high.

[0006]

[Problems to be solved by the device]

 The present invention solves the above-mentioned problems, can be easily assembled, has a sufficient joint strength, and can be easily attached so that the lashing rail does not protrude to the inside of the track body. It is an object to provide a corrugated block for a truck body that enables It is also an object of the present invention to provide a corrugated block having excellent heat insulating properties.

[0007]

[Means for Solving the Problems]

 In the corrugated block for track body of the present invention, the strip-shaped corrugated plate and the flat plate are positioned in parallel in the vertical direction with a certain space therebetween, and between the corrugated plate and the flat plate, a long length is provided to vertically support them. A support plate is provided parallel to the direction and is integrated in a state where a hollow portion is formed, and the corrugated plate has a plurality of corrugated portions protruding upward and parallel to the longitudinal direction. In the block body formed individually, the extension part of the flat plate projects from the end support plate on one side A of the block body to form a plate-like joint part 6a whose tip part is inclined upward, On the other side B of the block body, the extension of the corrugated plate projects from the end support plate, and the front end forms a plate-shaped joint 7a inclined downward, and the plate-shaped joint 7a of the corrugated plate does not exist. The side corresponds to the shape of the plate-like joint 7a along the side A. The groove is formed toward the lower inside of the hollow portion to form the groove-shaped joint portion 7b, and the plate-shaped joint portion along the side B is formed on the side of the flat plate where the plate-shaped joint portion 6a does not exist. A groove corresponding to the shape of the portion 6a is formed toward the upper inside of the hollow portion to form a groove-shaped joint portion 6b. A plurality of the above block bodies are joined to each other between adjacent block bodies by a plate-like joint. By fitting the portion 7a to the groove-shaped joint portion 7b and the plate-shaped joint portion 6a to the groove-shaped joint portion 6b, the end support plates adjacent to each other are brought into close contact with each other to form a flat plate. In addition, a strip-shaped groove extending in the entire length in the longitudinal direction is formed in the lower central part of the flat plate, and both ends of this strip-shaped groove have a U-shaped cross section and an inverted shape, respectively. It is characterized in that it is formed in a U shape.

First, the structure of the corrugated block for a truck body according to the present invention is illustrated in the drawings, and the present invention will be described in detail. FIG. 1 is a cross-sectional view showing the internal structure of an example of a corrugated block for a truck body of the present invention. In addition, FIG. 2 shows that a plurality of corrugated blocks of the present invention shown in FIG. 1 are arranged, adjacent block bodies are fitted together, fixed with rivets 12, and the lashing rail 10 is fitted into the band-shaped groove 13. It is a figure showing the state at the time of inserting.

As shown in FIG. 1, a corrugated block for a track body according to the present invention has a corrugated plate 1 and a flat plate 2 which are vertically parallel to each other with a certain space therebetween. A support plate 4 is provided in the space sandwiched between the two in parallel with the longitudinal direction so as to vertically support them, and thus the corrugated block is integrated with the hollow portion 5 formed therein. Has been done. Moreover, the corrugated plate 1 is formed with a plurality of corrugated portions 3 protruding upward in parallel to the longitudinal direction, and the corrugated plate 1 has a corrugated shape as shown in FIG. 1 in terms of strength and appearance. It is preferable that the portion 3 and the flat plate portion 8 are present at regular intervals.

Then, on one side A of the corrugated block of the present invention, the extension part of the flat plate 2 projects from the end support plate 4a and the tip part forms a plate-like joint part 6a inclined upward, On the other side B, the extended portion of the corrugated plate 1 projects from the end support plate 4b, and the front end portion forms a plate-shaped joint portion 7a inclined downward. Moreover, as grooves corresponding to the plate-like joint 6a and the plate-like joint 7a, on the side where the plate-like joint 7a of the corrugated plate 1 does not exist, the plate-like joint 7a is formed along the side A. A groove corresponding to the shape is formed toward the lower inside of the hollow portion 5a to form a groove-shaped joint portion 7b, while the side of the flat plate 2 where the plate-shaped joint portion 6a does not exist is located on the side B. Along the groove 5b, a groove corresponding to the shape of the plate-like joint 6a is formed toward the inside of the hollow portion 5b to form the groove-like joint 6b.

Further, in the corrugated block of the present invention, a plurality of the above block bodies can be integrated with adjacent block bodies in a flat plate shape, and the plate-like joint portion 7a is adjacent to the block body. Can be fitted with the groove-shaped joint 7b of the block, and the plate-shaped joint 6a can also be fitted with the groove-shaped joint 6b of the adjacent block. And 4b are in close contact. In the example illustrated in FIG. 1, the plate-like joints 6a and 7a and the groove-like joints 6b and 7b are inclined at an angle of about 45 °, but the present invention is not limited to this. The inclination angle can be changed as appropriate. As described above, in the present invention, since the joints 6a, 7a, 6b, 7b are inclined, a large joint strength is obtained regardless of whether the block is loaded in the parallel direction or the vertical direction. Shown, can be securely fixed with adjacent corrugated blocks. Further, due to the joint shape of the plate-like joint portion and the groove-like joint portion, excellent waterproofness can be obtained. In addition, in the structure shown in FIG. 1, the plate-shaped joint 7a constitutes a part of the corrugated portion 3 of the corrugated plate 1, and the corrugated block having such a structure has a good appearance after the joint. Therefore, it is preferable.

When joining the corrugated blocks of the present invention to each other, as shown in FIG. 2, the plate-shaped joints 7a of the adjacent corrugated blocks are joined to the groove-shaped joints 7b and the plate-shaped joints 6a. The grooved joint 6b is obliquely inserted and fitted, and the rivet 12 is driven into the flat plate joint 6a-groove joint 6b to be completely fixed. The entire block thus obtained by joining and fixing using the rivet 12 has sufficient strength as a track body, and the number of corrugated blocks to be joined can be arbitrarily selected. The overall width and height can be easily adjusted. In the corrugated block of the present invention, since each joint is fitted in a slanted state, the number of rivets 12 used at the time of joining is much smaller than in the case of pasting a conventional corrugated aluminum plate. Assembling work for the truck body becomes easy. In the present invention, screw screws may be used instead of rivets when joining the corrugated blocks.

Further, as shown in FIG. 1, a strip-shaped groove 13 extending along the entire length in the longitudinal direction is formed in the lower central portion of the flat plate 2 of the corrugated block for a track body of the present invention. Both ends 9a and 9b of the groove 13 are formed to have a U-shaped cross section and an inverted U-shaped cross section, respectively. The strip-shaped groove 13 is preferably provided so that the front surface of the lashing rail 10 does not protrude from the back surface of the corrugated block when the lashing rail 10 is mounted as shown in FIG. When mounting the lashing rail 10 as described above, the lashing rail 10 is pulled toward the both end portions 9a and fitted therein, and then the other end of the lashing rail 10 is fitted in the both end portions 9b. Then, as shown in FIG. 2, the rivet 14 is driven and fixed. Therefore, in the corrugated block of the present invention, since the lashing rail is entirely fitted and attached to both ends 9a and 9b of the band-shaped groove 13, the lashing rail does not need to have a great strength. However, even if it is made of aluminum, it is sufficient and the weight can be reduced.

In the present invention, the gap between the both ends 9a and 9b of the band-shaped groove 13 is not limited as long as the lashing rail can be inserted and the lashing rail can be stably supported. It is not something that will be done. FIG. 2 shows a state in which the lashing rails 10 are inserted into the both ends 9a and 9b, and the lashing rails 10 can be adjusted so that the position of the lashing belt can be adjusted according to the position of the luggage. A plurality of fixing holes 11 are provided at regular intervals. At this time, the method of fixing the lashing rail 10 is not particularly limited, but generally, the lashing rail 10 is fixed to the flat plate 2 using rivets 14 as shown in FIG. Further, in the corrugated block of the present invention, when the lashing rail is not attached, a surface protection material having substantially the same size as that of the lashing rail is provided at the position of the above-mentioned strip groove 13, for example, a strip-shaped flat wood or plastic material. Is preferably attached, and by attaching the surface protective material in this manner, it is possible to prevent the dent from occurring even when the flat plate 2 is impacted.

In the present invention, the support plate 4 is preferably provided at the center of the corrugated portion 3, that is, at the most raised position, as shown in FIG. The strength of the corrugated block is maximized. Moreover, in the present invention, since the hollow portion 5 is formed inside the corrugated block, the weight of the block can be reduced. Further, in the case of the corrugated block of the present invention as shown in FIG. 1, since the corrugated portions 3 are present at regular intervals in the entire block after joining, a track body excellent in design is obtained. can get.

The thickness of the corrugated sheet 1 and the flat sheet 2 in the present invention is preferably selected appropriately according to the application of the vehicle and the size of the vehicle, but is not particularly limited, but generally about 1.0 to The thickness of the support plate is preferably about 1.2 mm, and the thickness of the support plate is preferably about 1.2 mm. Further, the distance between the corrugated plate 1 and the flat plate 2 is not particularly limited, but it is generally preferably about 30 to 40 mm. On the other hand, the width of the corrugated block of the present invention is not particularly limited, but generally, it is preferable to set the width to about 100 mm, 200 mm, and 300 mm, and to combine them appropriately according to the size of the track body. In this case, the corrugated block of the present invention can be freely combined. Further, the corrugated blocks of the present invention may be arranged alternately with the corrugated blocks having no band-shaped groove, and one or two such corrugated blocks may be arranged between the corrugated blocks of the present invention. Preferably. Further, the material of the corrugated block of the present invention is not particularly limited, and general metals and the like can be widely used. However, in order to reduce the weight of the corrugated block itself, aluminum is used. Particularly suitable.

Furthermore, the present invention is characterized in that the hollow portions 5, 5a and 5b formed by the corrugated plate 1, the flat plate 2 and the support plate 4 described above are filled with urethane and / or styrofoam. It is also a corrugated block for bodies, and this corrugated block is also excellent in heat insulation. Particularly, in the present invention, the end supporting plates 4a, 4b of the corrugated block are closely fitted to the end supporting plates 4b, 4a of the adjacent corrugated blocks, and all the hollow parts 5 are filled with the heat insulating material. Since it has the advantage that it can be a corrugated block, and the heat insulation of the entire track body can be improved, it is possible to fabricate a track body with very little influence of temperature changes around the track. It can be used for refrigerated vehicles. It can be widely used for urethane and Styrofoam used at this time.

On the other hand, as a flat plate corresponding to this corrugated plate, plate-shaped joints and groove-shaped joints corresponding to the joints of the corrugated plate are provided at both ends as shown in FIG. A strip-shaped groove was formed, and both ends were formed into a U-shaped cross section and an inverted U-shaped cross section, respectively. Then, the corrugated plate and the flat plate are arranged so as to be parallel to each other with a space of 30 mm, and the corrugated plate and the flat plate are vertically thickened so as to vertically support them. A supporting plate having a thickness of about 1.2 mm was provided to integrate the corrugated plate and the flat plate. At this time, each support plate is positioned at the center of the corrugated portion as shown in FIG. 1, the plate-shaped joint portion and the groove-shaped joint portion formed on the corrugated plate side are fitted to each other, and the support plate is formed on the flat plate side. When the plate-like joint and the groove-like joint were fitted together, the adjacent end support plates were in close contact with each other.

Next, a plurality of corrugated blocks for track bodies according to the present invention thus prepared are prepared, and the plate-like joints and the groove-like joints provided at both ends are sequentially fitted obliquely. After combining, a rivet was driven into the joint portion on the flat plate side and fixed to each other as shown in FIG. 2 to form a track body. In addition, a commercially available lashing rail having a width of about 13 cm was inserted into the strip-shaped groove on the flat plate side, and a rivet was similarly driven to fix the lashing rail to the flat plate. When the above corrugated block for track body is used, the track body can be easily manufactured by simply fitting the plate-like joint part and the groove-like joint part together, and in addition, The track body produced by the above had sufficient strength. In addition, the corrugated block of the present invention was able to secure a sufficient luggage loading space when the lashing rail was attached, and was also sufficient in terms of the attachment strength of the lashing rail.

Example 2 A corrugated block for a track body manufactured in Example 1 was filled with the commercially available styrofoam in the hollow portion, and then the track body was bonded to each other in the same manner as in Example 1 to form a track body. Was produced. The truck body thus obtained had excellent heat insulating properties, was not easily affected by the ambient temperature, and could keep the temperature inside the body substantially constant.
