BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting structure of a center pillar of a loading bed torii, and more particularly, a connecting structure of a middle pillar of a loading board torii which is connected upright from a connecting portion between a vertical joist and a horizontal joist of the loading board. About.

2. Description of the Related Art Referring to FIGS. In FIG. 1, two middle pillars 3 stand upright at a torii gate 2 provided on the driver's cab side of a loading platform 1 as shown in the figure. The center pillar is formed of an L-shaped steel material. In FIG. 2, which is an enlarged view of a portion surrounded by a circle in FIG. 1, a horizontal joist 4 and a vertical joist 5 provided under the floor of a cargo bed are mutually connected by anchor bolts 6 extending vertically. 2 and 3 at the connecting portion between the horizontal joist and the vertical joist.
2 and 3, the lower joist 5 is bolted to the vertical joist 5 by a bolt 8. The connection of such a structure has the advantage that it is simple, as described above, by merely bolting the center column by the use of the bolts 7,8.

[0003]

[Problem to be Solved by the Invention] However, in connection of such a structure, the horizontal joist and the vertical joist are made of wood. Loose parts appear and rattle, and the rattle causes the bolt holes to become large, causing cracks 9 in the vertical joist 5 as shown in FIGS. There was a problem of falling down on the platform side.

Accordingly, an object of the present invention is to solve the problems of rattling, cracking, and falling down of the center pillar due to drying of the horizontal joist and the vertical joist, changes over time such as wrinkles and shrinkage, and the like. To provide a connection structure for the center pillar.

In order to achieve this object, according to the present invention, the connecting portion of the center pillar of the loading platform torii which is connected upright from the connecting portion between the vertical joist and the horizontal joist of the loading platform has a horizontal joist and a vertical joist. A connecting plate is interposed between the joist and the center pillar, and the connecting plate is shaped to be bolted with the horizontal joist sandwiched between the connecting plate and the center pillar, and other connecting plates are provided. There is provided a connecting structure of a middle pillar of a loading platform torii which is shaped to be bolted together with both joists by an anchor bolt connecting the vertical joist and the horizontal joist at a portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In the present invention, the connecting portion of the middle pillar 3 of the loading platform torii which is connected so as to be upright from the connecting portion of the vertical joist 5 and the horizontal joist 4 of the loading platform includes the horizontal joist 4 and the vertical joist 5 and the middle pillar 3. The connecting plate 11 is interposed between the two. The details of this connecting plate 11 are best shown in FIG.

As shown in FIG. 7, the connecting plate 11 is basically formed by forming a single steel plate having a constant width and height in a stepped shape. The lower part 12 of the connecting plate 11
In order to maintain the shape of the connecting plate 11 formed in a stepped shape, a reinforcing triangular plate 13 is welded to both sides. The width of the connecting plate 11 is selected to be a size that holds the horizontal joist 4 at the connecting portion at a fixed length and covers the length of the vertical joist 5 in the width direction. The upper connecting plate portion 14 extends toward the front side in FIG. 7 by a horizontal portion 15 corresponding to the width of the horizontal joist 4 with respect to the lower connecting plate portion 12. Then, the lower connecting plate portion 12 is positioned at the right side of FIG.
A support bracket 16 is welded to the side below the horizontal portion 15 by the height of the vertical joist 5. This support bracket 1
The size 6 has a length and a width capable of supporting the vertical joist 5 by a certain length.

The connecting plate 11 having the above-mentioned shape has a portion 18 (a left portion in FIG. 7) shaped to be bolted with the horizontal joist 4 sandwiched between the connecting plate 11 and the center pillar 3, and an anchor. It has a portion 19 (the right portion in FIG. 7) which is bolted together with the vertical joist 5 and the horizontal joist 4 by the bolt 6.

FIGS. 4 to 6 show a state in which the middle pillar 3 is connected to the connecting portion of the horizontal joist 4 and the vertical joist 5 using the connecting plate 11 having such a structure. As shown in FIG.
The connecting plate 11 is fastened by bolts 21 with the horizontal joist 4 interposed between the upper portion 14 and the middle pillar 3. A hole 22 is formed in the connecting plate 11 for bolting. Further, the lower portion 12 of the connecting plate is directly tightened with a bolt 23 on the middle pillar 3, and a bolt hole 24 is formed in the connecting plate. As shown in FIGS. 4 to 6, in the portion 19, the support bracket 16 and the horizontal portion 1 are joined together with both joists by the anchor bolts 6 connecting the vertical joists 5 and the horizontal joists 4.
5 is bolted. For this bolting, a hole 26 is formed in the support bracket 16 and a hole 27 is formed in the horizontal portion 15.

[0010]

According to the present invention, the connecting plate is interposed between the horizontal joist and the vertical joist and the middle pillar, and the horizontal joist is sandwiched between the connecting plate and the middle pillar with bolts. Anchor bolts connecting the vertical and horizontal joists at other parts of the board can be bolted together with both joists, improving the strength of the connection between the torii center pillar and the horizontal joist and the connection between the center pillar and the vertical joist, and the vertical joist etc. Eliminates cracks and increases in holes and prevents rattling. In addition, the presence of this connecting plate allows the connection work between the vertical joist, the horizontal joist and the center pillar from one direction, improving the assembly workability. I do.
