The reinforcing connecting pieces 70 and 70 'are best connected to the inner surface and the end of the scene portions 10 and 20 corresponding to the vertical recesses 16. However, the vertical groove 16 may be connected between the inner surfaces of the scene portions 10 and 20 where the vertical grooves 16 are not formed.

Hereinafter, the use of the firewall according to the present invention having the configuration as described above will be described in detail.

The protective wall 1 of the present invention fills and uses liquids in the spaces S1 and S2 formed therein. When moving, the protective wall 1 is made of synthetic resin in a liquid-free state. .

First, it is necessary to minimize the space required when producing and storing the protective wall (1) or transported to the installation site. Accordingly, the upper end portion of the barrier wall 1, which is placed on the lower side, is inserted into the stacking space 66 of the barrier wall 1 on the upper side. A state where the upper end of the barrier wall 1 is inserted into the stacking space 66 is indicated by a dotted line in FIG. 4. When the protective walls 1 are stacked in this manner, the protective walls 1 can be more stably positioned in a relatively narrow space.

After the barrier 1 has been moved to the place for installation, the adjacent barriers 1 must be joined together. To this end, the first end face portion 30 and the second end face portion 40 of the adjacent barrier 1 are adjacent to each other, and the male fastening portion 32 'of the first end face portion 30 is connected to the second end face portion 30'. It is to be seated on the female fastening portion 42 'of the end portion (40). That is, for example, the male fastening portion 32 'of the other protective wall 1 is inserted into the female fastening portion 42' of the one-side protective wall 1 placed on the center line. ) Is positioned above the female fastening portion 42 'of the adjacent barrier 1.

Next, the protective wall 1 having the male fastening portion 32 'may be moved downward from the upper portion of the female fastening portion 42' to fasten the male fastening portion 32 '. After connecting the plurality of barriers 1 in this manner, the liquid is injected into the spaces S1 and S2 through the injection holes 58. When the liquid is completely filled in the spaces S1 and S2, the weight of the entire protective wall 1 becomes heavy and is stably supported on the road surface, so that it is not easily moved even when an external force is applied.

On the other hand, the through passage 12 and the vertical grooves 18 formed in the first and second surface portions 10 and 20, the upper cross section groove 56 formed in the upper surface portion 50, the lower surface portion Since the lower surface transverse groove 62 and the curved surfaces 33 and 43 of the first and second end portions 30 and 40 formed on the 60 serve to reinforce the strength of the appearance of the protective wall 1, For example, even if an external force is applied, such as a vehicle colliding with the firewall 1, the damage or deformation of the appearance of the firewall 1 is not caused.

In addition, the first and second reinforcing connection pieces 70 and 70 ′ in the interiors of the spaces S1 and S2 are particularly deformed by the liquid filled in the spaces S1 and S2. To prevent damage. That is, the reinforcing connecting pieces 70 and 70 'are filled with the first and second scene portions 10 and 20 of the protective wall 1 due to the weight of the liquid, for example, while the temperature of the liquid is lowered. It causes a phase change to prevent deformation of the protective wall (1) by the volume change occurs.

Next, when it is necessary to move the protective wall 1 used as mentioned above, the said drain port 64 is opened first, and the liquid filled in the said spaces S1 and S2 is discharged | emitted to the outside. After all the liquid in the space (S1, S2) is discharged because the weight of the barrier 1 is reduced, the operator can easily separate and move the barrier 1 in the other barrier (1).

The scope of the present invention is not limited to the embodiments described above, but may be defined by the scope of the claims, and those skilled in the art may make various modifications and alterations within the scope of the claims It is self-evident.
