Description

  The present invention relates to a windsock for a building site that indicates the wind speed (wind force) and the wind direction of the wind blown at the building site.

  In general, in a construction site (construction site), building materials are suspended and conveyed by heavy cranes, and a construction worker works on a building such as a building or a house under construction. The wind (crosswind) blown at the construction site shakes the construction materials suspended by heavy cranes and is blown by construction workers who work on the building. It is necessary to ascertain and confirm the wind speed (wind power) and direction to ensure the safety of construction work.

  Patent document 1 discloses a windsock as a technique for confirming the wind speed and direction of the wind blown at a building site. In Patent Document 1, a windsock is configured to include a long cylindrical windstream body, a ring-shaped core material that opens an inlet of the windstream body, and a hanging rope connected to the inlet side of the windstream body. It is suspended from the installed pole. The windsock is fastened from the shaft end side of the pole by fastening the suspension rope to the shaft end side of the pole. The wind blown at the construction site flows into the wind flow body from the inlet of the wind flow body, and soars the wind flow body toward the axial end of the pole. Thereby, the construction worker can grasp | ascertain and confirm the wind speed (wind power) and wind direction of the wind which blows in a construction site by observing the inclination angle and inclination direction of a wind-flow main body.

However, in Patent Document 1, when the inlet (ring-shaped core member) of the wind flow body is set to be larger than the diameter of the pole and the suspension rope is longer than between the pole end and the fastening portion of the suspension rope, The wind current body blows up to the sky above the pole end of the pole due to the strong wind blowing at the site, and the inlet of the wind stream body faces the pole end. When the strong wind at the building site calms down, the main stream body falls toward the end of the pole. With this fall, the pole enters the wind flow body from the inlet of the wind flow body, and the wind flow body covers the pole.
As described above, when the wind current body covers the pole, the construction worker at the construction site cannot grasp and confirm the wind speed and direction of the wind blowing at the construction site, and further requires the work of removing the wind current body from the pole. Moreover, there is a possibility that the wind main body may be damaged due to the entry of the pole into the wind main body.
