Therefore, the present invention has been made in order to solve such a problem, and is a wall in which the load of the wall portion constituting the box-type cargo bed acts on the vertical joists constituting the floor portion constituting the cargo bed. It aims at providing the connection structure of a floor part and a floor part.
[0011]
Another object of the present invention is to provide the above connection structure in which the side member of the floor portion does not crack.
[0012]
Furthermore, another object of the present invention is to provide the above-described connection structure in which the skeleton member constituting the lower end of the wall portion and the floor member constituting the floor portion and connected vertically to the vertical joists are integrated. is there.
[0013]
[Means for Solving the Problems]
The connecting structure of the present invention that achieves the above object comprises a bottom part of a wall part in a box-type cargo bed having a floor part and a front wall part and a rear wall part connected to the front and back of the floor part. This is a connection structure of a horizontal frame member and a floor. The floor portion has a plurality of floor members that are vertically connected to the vertical joists, and the frame member of the wall portion is integrally connected to the floor member at the end. Here, a perpendicular passing through the center of gravity of the wall passes through the floor member at the end.
[0014]
Here, the floor member at the end is preferably composed of an elongated upper plane and a side plane extending downward from both sides of the upper plane along the longitudinal direction. At this time, the lower ends of the both planes are connected to the vertical joists. Is done. The skeleton member has an elongated upper surface, a side surface extending downward from one edge along the longitudinal direction of the upper surface, a vertical side surface extending downward from the other edge along the longitudinal direction, and the vertical side surface, It is desirable that the bottom end of the side surface extending downward from one edge of the skeleton member is joined to the top plane of the end floor member, and the horizontal bottom surface. The end of the is joined to the side plane of the end floor member.
[0015]

4 and 5 are respectively a partially enlarged perspective view of a box-type cargo bed having a coupling structure according to the present invention and including a floor portion and a wall portion connected to the floor portion, and the box shape. It is a partial center expanded horizontal sectional view of a loading platform.
[0016]
The present invention relates to a connection structure between a wall and a floor constituting a box-type carrier, and is otherwise the same as the above-described prior-art box carrier, and therefore, common elements have the same reference numerals. Is attached.
[0017]
The floor portion 3 of the box-type carrier 1 shown in the figure has two parallel vertical joists 26 like the conventional one, and a plurality of floor members 27 perpendicular to these connect the connecting tool 30 (FIG. 5). Then, it is fixed to the vertical joists 26 with bolts, and a flooring 28 is stretched thereon. A floor member 40 is located at the end of the floor 3.
[0018]
The end floor member 40 is composed of an elongated upper plane 41 and side planes 42 and 43 extending downward from both sides of the upper plane along the longitudinal direction. In this embodiment, the side plane 42 is fixed to the vertical joists 26 via bolts 31 with bolts. The other side plane 43 is directly connected to the vertical joist 26 by bolts.
[0019]
The wall 4 is composed of a horizontal skeleton member 46 constituting the lower end, frame members 22 and 23, and an auxiliary frame member 24 (and an upper frame member (not shown)), and a panel 25 is stretched thereon. Has been. As shown well in FIG. 5, the skeletal member 46 has an elongated upper surface 47, a side surface 48 extending downward from one edge of the upper surface along the longitudinal direction, and a longitudinal direction of the upper surface. The vertical side surface 49 extends downward from the other edge, and a horizontal bottom surface 50 of the vertical side surface extends horizontally along the longitudinal direction. The side surface 48 is connected and fixed to the upper plane 41 of the floor member 40, and the horizontal bottom surface 50 is connected and fixed to the side plane 43 of the floor member 40.
[0020]

The side surface 48 is connected and fixed to the upper plane 41, and the horizontal bottom surface 50 is connected to and fixed to the side plane 43.
[0021]
In the illustrated embodiment, the skeleton member and the floor member are connected so that a quarter of the cross section of the skeleton member 46 overlaps the floor member 40. May be. However, when the skeletal member is joined so as to be completely placed on the floor member, the volume in the cargo bed is reduced.
[0022]
【effect】
By adopting the connecting structure of the present invention, the weight of the wall portion is applied to the entire floor member at the end portion. Since the floor member is rigidly connected to the vertical joists, the weight of the wall portion acts on the vertical joists. Therefore, a rigid connection is achieved between the wall and the vertical joist, and as a result, the structure of the box-type carrier is more rigid.
[0023]
In particular, a cargo bed with a wing-type roof differs from a box-type cargo bed where the roof, side walls, and floor are connected to each other, and is composed of a connection between the floor and the front and rear walls. In particular, when the wing roof is opened and closed, an irregular load is applied to the frame material that forms the lower end of the wall. However, with the joint structure of the present invention, the load from the wall is vertical. It acts on the joist, so the load acting on the joint between the floor member at the end and the side frame that forms the side surface of the floor is significantly reduced, and as a result, cracks and the like are prevented from occurring at this joint. be able to.
