2. Description of the Related Art Conventionally, a small building unit has a substantially rectangular shape (horizontally long) and is set to a size capable of being mounted on a bed of a vehicle for transportation. Here, for example, the length of the bed of a vehicle for transporting a small building unit (4 ton vehicle) is set so that the work of mounting the small building unit on the bed or the operation of removing it from the bed will not hinder the operation of the cab (cabin). ) Is able to secure some space from the back, and the size is set so that it can be installed with a margin including the rear lower end of the small building unit.

In order to provide a more comfortable living space (space), the small building unit may have a special specification in which a predetermined volume is expanded, for example. If the small building unit with special specifications is mounted on the bed of a 4-ton vehicle, the entire length (dimension along the longitudinal direction of the bed) is longer than the rear end surface of the bed, and the rear end portion protrudes from the rear end surface of the bed. It is considered that the vehicle is in a state of being bent, twisted, distorted, or the like due to the weight of the rear end portion of the vehicle at the time of traveling to deteriorate the quality. Therefore, the vehicle is normally transported by using a 6-ton vehicle or an 11-ton vehicle.

[0004]

However, when a 6 ton vehicle or an 11 ton vehicle for transporting the special-purpose small building unit is used, the transportation cost becomes high and the road to the transportation destination becomes high. It may be difficult to transport unless it is narrow and a 4-ton car is used. Therefore, there is room for improving the transportability of the special-purpose small building unit while maintaining the quality even when using a 4-ton vehicle.

The present invention has been made in view of the above problems, and enables even a specially designed small building unit to be transported by a 4-ton vehicle while maintaining its quality, and to reduce the transportation cost. An object of the present invention is to provide a reinforcement jig that can be used for transporting a small building unit.

A reinforcing jig for transportation of a small building unit of the present invention is detachably attached to a rear lower end portion of a small building unit to be mounted on a cargo bed of a vehicle and transported, and is attached to the rear lower end portion. A horizontal reinforcing plate portion that abuts horizontally and is fixedly held; a vertical reinforcing plate portion that is continuously provided on the horizontal reinforcing plate portion in a vertical direction and extends vertically along the rear end face of the luggage carrier; It is characterized in that it comprises a locking convex portion that fits into a mounting concave portion provided on the luggage carrier, and comprises a sandwiching plate portion that is sandwiched between the rear lower end portion of the small building unit and the luggage carrier.

The transportation reinforcing jig having the above-mentioned structure is a small building unit of a normal specification (hereinafter referred to as a normal small building unit).
Used to transport a special-purpose small building unit (hereinafter, referred to as a custom-built small building unit) that is expanded in the length direction of the bed of the vehicle using a vehicle that transports the vehicle. The transportation reinforcement jig is detachably attached to the rear lower end portion of the custom-made small building unit before the custom-made small building unit is mounted on the bed of the vehicle as a transportation target. That is, in the transportation reinforcing jig, the horizontal reinforcing plate portion is horizontally held in contact with the rear lower end portion of the custom-built small building unit and fixed.

Next, the custom-made small building unit is mounted on the bed of the vehicle with the horizontal reinforcing plate portion of the reinforcing jig for transportation fixedly held at the lower rear portion. Then, in the transportation reinforcing jig, the engaging projection of the sandwiching plate portion is fitted into the mounting recess of the luggage carrier, and the sandwiching plate portion is sandwiched between the rear lower end portion of the custom-built small building unit and the luggage carrier. In this state, the reinforcing jig during transportation is in a state in which the vertical reinforcing plate portion that is continuous with the horizontal reinforcing plate portion is in a state of vertically abutting (locking) along the rear end face of the luggage carrier. The rigidity to withstand the gravity behind the custom-built small building unit that acts on the section with a margin is obtained.

Therefore, the transportation reinforcing jig is composed of a horizontal reinforcing plate portion and a vertical reinforcing plate portion for abutting the rear end face of the custom-made small building unit mounted on the loading platform of the vehicle to the horizontal reinforcing plate portion,
It can be firmly supported in a position parallel to the loading surface of the loading platform,
