2. Description of the Related Art As is well known, at a road construction site or a construction site, a moving fence is installed temporarily to prevent traffic and to prevent unrelated persons from entering the site. Measures will be taken to specify the prohibited areas.

By the way, since it is difficult for this type of moving fence to fall down due to wind or a small impact, a weight such as a sandbag filled with soil or a hollow container capable of being filled with water or sand is placed on the lower part of the moving fence. In many cases, the moving fence is prevented from falling down.

Among such weights such as sandbags and hollow containers, the hollow container is useful as a weight of a movable fence because it is light and convenient to carry. For example, a movable fence H as shown in FIG.
In the movable fence H on which the underbars U and U are erected, hooks Bf and Bf at both ends of a hollow weight B ′ filled with a load such as water and sand are hooked on the underbars U, respectively. Weight B 'is connected to two underbars U and U
It is placed so that it spans between.

However, in the case of this type of moving fence H, if the distance between the two underbars U, U differs depending on the type of moving fence H, the hollow weight B 'cannot be hooked, and Even if it is possible, the hollow weight B 'cannot be stably mounted. Therefore, a plurality of types of hollow weights B' that can be mounted for each type of the moving fence H must be prepared. There is a problem that the cost increases and the economic burden increases.

A moving fence H as shown in FIG. 12, that is, a moving fence H in which only one underbar U is erected between the A-shaped stands S on both sides, has the above-described hollow structure. Since it is difficult to mount the weight B 'stably, the sandbag D is often mounted on one underbar U to prevent the movable fence H from falling over, as shown in FIG. Therefore, it was very difficult to carry the heavy sandbag D, and the appearance of the construction site was not very good.
