According to the construction safety fence of the present embodiment, there is a great effect for those who pass around the construction safety fence installed in the passage to arrange the sections divided at the installation location of the road surface and prevent the passage.

According to the construction safety fence of the present embodiment, it is possible to reliably transmit an intention to prevent intrusion into the site beyond the construction safety fence.

In addition, the meaning of the construction safety fence installed in the passage can be reliably communicated to passersby visually.

Further, according to the construction safety fence of the present invention, the overall height is low and the center of gravity is low. The upper tier uses a lightweight flat plate at a low position b from the top surface, and the lower tier uses lower reinforcement members 15 and 35, which are hollow square lumber members with high rigidity, at a position a distance from the ground at the lowest possible position. .. As a result, the hollow iron material with high rigidity that can withstand the load of the panel with a low center of gravity has a stable structure that does not easily tip over even if it is blown by the wind.

Such a structure realizes a device in consideration of the position, material, shape, weight, wind-induced fanning, weather, etc. of each element constituting the structure. For each element, considering the appropriate material, shape, weight, size, and length, we have created a structure that is both lightweight and highly rigid, and has corrosion resistance and rust resistance.

By using the right material in the right place in consideration of the specific gravity and the right place in the structural form, it is an excellent structure that is not uniform and realizes ingenuity.

Further, as for the members constituting the construction safety fence of the present invention, since iron members are frequently used for the components other than the panel, easy movement from the above-mentioned installation place is suppressed by using a material having a large specific density. The effect is increasing.

Therefore, according to the construction safety fence of the present invention, the overall height is low and the structure has a low center of gravity, so that it is not easily blown by the wind.

At the time of assembly processing, the number of parts is small, processing is easy, and it can be manufactured at a relatively low cost.

At the time of transportation, the structure that makes the total height as low as possible has the effect of reducing the weight as much as possible and making it easy to transport.

According to the construction safety fence of the present invention, it is possible to surely alert those who walk around the installation site to prevent intrusion into the site, and of course, to convey the message written on the panel to those who pass by. It is possible to exert an advertising function in addition to a function to prevent intrusion into the site.

The advertising function can be demonstrated by the cautionary notes and advertisements displayed on the panel together with the role as a barrier and obstacles to prevent the original intrusion.

In addition, since the display contents of the panel can be easily replaced, there is an effect that the construction safety fence can have a function as an advertising medium in addition to the intrusion prevention function.

According to the construction safety fence of the present embodiment, the upper reinforcing members 14 and 34 adopt flat plates to reduce the weight, while the lower reinforcing members 15 and 35 are tubular high-rigidity members which are hollow square lumbers having a rectangular cross section. The lower tier, which is more loaded than the upper tier, has a solid structure.

As described above, in the above embodiment, the thickness of the hollow square timbers of the lower reinforcing members 15 and 35 is 50 mm, whereas the thickness of the flat plates of the upper reinforcing members 14 and 34 is 5 mm. It has a low center of gravity and is not easily blown by the wind, making it difficult to fall.

Since the lower connecting member 28 is a hollow square lumber having a rectangular cross section, high rigidity is ensured.

The height distance b from the top position of the upper connecting member 18 to the total height position is twice or more the above-ground height distance a of the top position of the lower connecting member 28. As a result, the structure has a low center of gravity.

Since the cap member 16 for connecting the joints of the first leg 13 and the second leg 23 and the joints of the first leg and the second leg is provided, it is safe and less likely to cause trauma.

The first leg, the second leg, the third leg, the fourth leg, the first upper reinforcing member, the second upper reinforcing member, the first lower reinforcing member, the second lower reinforcing member, the upper Since the panel rail, the lower panel rail, the upper connecting member, and the lower connecting member are made of iron, they are stable and difficult to tip over.

Since the panel 11 is made of resin, it is lightweight.

Since the lengths of the upper connecting member, the lower connecting member, the upper panel rail, and the lower panel rail in the longitudinal direction can be adjusted, the members can be changed according to the situation of the installation location. It is efficient because it can be used.
