By the way, as described above, when a plate-shaped member such as a corrugated cardboard sheet is erected and used as a partition, stress tends to concentrate on the edges and corners of the plate-shaped member. There is a problem that it is easily deformed or damaged. In particular, the lower edge of the plate-shaped member is easily deformed or damaged because it is pressed against the floor surface while receiving the load of the plate-shaped member itself, and if the lower edge is deformed or damaged, the upright state of the plate-shaped member is not good. It may be stable.

In Patent Document 1, the foot plate portion is bent and formed on the lower edge portion of the partition wall member, and it can be expected that deformation or breakage of the lower edge portion is suppressed. However, simply bending the foot plate portion is not enough. It is difficult to hold the wall surface portion and the foot plate portion at a right angle, and the standing state of the partition wall member may become unstable. In addition, the work of bending the foot plate portion is complicated. Therefore, there is room for improvement in order to stabilize the plate-shaped member in an upright state while suppressing deformation or breakage of the lower edge portion of the plate-shaped member.

The present invention uses a partition reinforcing tool capable of stabilizing the plate-shaped member in an upright state while suppressing deformation and breakage of the edge portion of the partition body formed by erecting the plate-shaped member. One of the purposes is to provide a partition.

A body portion formed of a first L-shaped angle material made of paperboard having a vertical facing portion and a first horizontal plane portion extending in the horizontal direction, and a main body portion formed along the first vertical facing portion. It is characterized by having a groove portion into which an edge portion of the partition body is fitted.

The partition of the present invention is characterized by comprising a partition main body formed by erecting a plate-shaped member, and the partition reinforcing tool attached to either the upper or lower edge of the partition main body. There is.

By attaching the partition reinforcing tool of the present invention to the edge portion of the partition body, the edge portion is reinforced and protected, and deformation or damage of the edge portion is suppressed. Further, when this partition reinforcing tool is attached to the lower end edge of the partition body, the first horizontal surface portion abuts on a horizontal base surface such as the floor surface, and the partition reinforcing tool aligns the partition body with the first vertical surface portion. Since it stably supports the vertical standing state, the partition assembly work becomes easy.
