The structural glue 4a is formed by laminating and bonding dried plate members (cutting plates) 5a with their fiber directions mainly parallel to each other. In general, the structural glued lumber 4a has a significantly reduced moisture content due to sufficient drying in a sawn board state, and since knots and decay, which are the drawbacks of wood, have been removed, 1.5 times of raw wood is used. The above strength is guaranteed. Further, since the structural glued laminated material 4a is not easily deformed, a gap is hardly formed, and the heat insulating and airtight performance can be maintained for a long time.

The rigid foam type heat insulating material 6a includes a celluloid type material such as rigid polystyrene and a hard urethane type material. The rigid foam-based heat insulating material 6a has high heat insulating performance and does not absorb water. However,
The rigid foam-based heat insulating material 6a is generally weak to light and has a property of being deteriorated by light.

The surface member 3a is composed of four elongated plate members each having the same size as the four side surfaces of the pillar main body 2a. Each surface material 3a is bonded to the periphery of the side surface so as to cover the periphery of the side surface of the pillar body 2a.

In the heat insulating column member 1a of the first embodiment shown in FIGS. 1 and 2 (A), the column main body 2a is formed by laminating a hard foam type heat insulating material 6a outside the laminated material 4a in parallel with the plate member 5a. It is composed. In the heat insulating column member 1b according to the second embodiment shown in FIG. 2B, the column main body 2b is configured by sandwiching the laminated member 4b between two hard foam type heat insulating members 6b parallel to the plate member 5b.
In the heat insulating pillar 1c of the third embodiment shown in FIG.
The column main body 2c is formed by stacking a hard foamed heat insulating material 6c in parallel with the plate material 5c at an intermediate portion of the plurality of laminated materials 4c. The position at which the rigid foam-based heat insulating material 6c is sandwiched is not limited to the intermediate portion, but may be adjusted according to the construction place or construction method.

Further, in the heat insulating column member 1e, since the hard foamed heat insulating material 6e outside the laminated material 4e is covered with the surface material 3e, the hard foamed heat insulating material 6e is separated from the laminated material 4e by the surface material 3e. Can be prevented.
