2. Description of the Related Art As is well known, a traffic sign is widely used in the field of construction and civil engineering in order to prevent danger at construction sites and the like.

[0003] As a conventional traffic sign, a heavy traffic sign formed of a heavy metal member so as not to easily fall down due to wind or the like is widely used. In addition, many of these indicators are of an integral type, and are bulky and require a large space during transportation and storage. The use of such a heavy and bulky indicator is a very heavy labor for the workers at the site, and a large occupied space and a heavy burden are imposed on the operators who transport and store the indicator.

[0004] Therefore, in order to obtain a sign lighter as much as possible, a sign is formed by using a lighter material or a thinner and thinner member. Also, in order to reduce the space occupied during transportation and storage as much as possible, a smaller size indicator or a foldable indicator was adopted.

[0005] However, in the case of the former lightweight sign, if it is too light, it falls down due to wind or the like, and there is a serious disadvantage that the sign, which is the most important function of the sign, cannot be fulfilled. When a thin and thin material is used, there is a drawback that the strength of the indicator is weakened and the durability is deteriorated.

In the case of the latter space-saving indicator, there is a limit to reducing the size of the indicator, and if the indicator is not provided with a minimum size required to perform the warning function. In addition, even if a foldable structure was adopted, the space could not be significantly reduced.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems in a sign used to prevent danger at a construction site and the like, and uses a hollow lightweight member. Therefore, it is a technical problem to provide a practical plastic hollow indicator that can reduce the burden on site workers and can be stably installed by filling a fluid such as water into the inner space. It is assumed that.

[0008] Another technical problem of the present invention is that the use of a separate type lightweight member makes it possible to greatly reduce the storage space and the like and to make it possible to easily assemble a plastic at a required installation place. An object of the present invention is to provide a hollow indicator.
