However, although the fall prevention fence described in Patent Document 1 is effective as a fall prevention fence for vehicles, the gap is too large only with the horizontally provided beam members (divided guardrails 22 to 28), and as a fall prevention for a person. Was inadequate.

Therefore, in addition to the beam material for preventing the vehicle from falling, a fence, which is a panel material, is installed as a measure to prevent the person from falling. However, when a fence is attached to an existing structure such as a multi-storey car park, it is naturally necessary to withstand the load acting on the fence such as a load leaning on a person or a wind load.

For this reason, when a fence for preventing a fall is attached to a beam material for a bollard, conventionally, as shown in FIG. 10, a gusset plate for attaching the fence is installed at a position where the support of each fence is attached at a site or the like. It was welded, and there was a problem that the fence columns could not be fixed at any position.

In addition, even when bolting is used instead of welding, on-site welding, sizing, and processing at a factory or the like that reflects the sizing are required, which causes a problem that the construction period is delayed. It is possible to actually measure and drill holes at the site without processing at the factory, but if you do so, cutting chips of steel materials will be generated due to the drilling work at the site, and the cutting chips cannot be completely removed. There was a problem that the pavement and finishing materials were received and rusted and soiled.
