Title:
FRP ANTENNA COLUMN PIPE, FRP ANTENNA COLUMN, AND MANUFACTURING METHOD OF FRP ANTENNA COLUMN PIPE
Document Type and Number:
Japanese Patent JP2022087747
Kind Code:
A
Abstract:
To provide an FRP antenna column pipe capable of suppressing damages of a pipe at a position near a flange member to which flexure deformation of a column against a wind reception weight in a light weight, an FRP antenna column, and a manufacturing method of the FRP antenna column pipe.SOLUTION: An FRP antenna column 10 is formed by bonding two FRP antenna column pipes 1 in serial, and fixing a flange member 2 for an installation surface fixing to one end. The two FRP antenna column pipes are bonded by inserting a bonding part into a cylindrical socket 3. The FRP antenna column pipe is manufactured by a filament winding method. A strong fiber contained in the FRP antenna column pipe has a fiber orientation of 80% or more, which is 15° or larger and 25° or less. The FRP antenna column pipe has a thickness of 8.5 mm or larger and 15 mm or less, and a diameter of 50 mm or larger and 160 mm or less.SELECTED DRAWING: Figure 1
