Description

  The present invention relates to a decorative column structure. For example, in an entrance porch such as a house, the present invention relates to a decorative pillar structure such as a porch pillar that supports an entrance fence.

In general houses and the like, for example, as a device for improving the design of the entrance porch, construction is performed to design the porch pillar that supports the entrance porch.
Conventionally, these constructions have been performed by spraying paint, pigments, or the like, but in recent years, construction has been performed in which a fixture is fixed to a column core and a decorative column member is attached to the fixture.

For example, Patent Document 1 discloses a core pillar having a square cross section, a pair of decorative cover members that are halved along the longitudinal direction of the core pillar and that covers the core pillar from the opposite side, and both the decorative cover members. The assembly-type decorative pillar is shown that includes a pair of attachment members connected at the butt joint portion and screw nails that secure the attachment members to the core pillar.
The both ends of the decorative cover member are formed with fitting grooves in which the both ends of each mounting member are accommodated.

  At the time of construction, both decorative cover members are combined with the core pillar interposed therebetween. As a result, a screw nail operating gap that is continuous in the longitudinal direction of the core column is formed between the joint surfaces of both decorative cover members. Subsequently, a screw nail inserted from a screw nail operating gap at a predetermined height position by inserting an attachment member downward from an upper end of a fitting groove formed facing between the joint surfaces of both decorative cover members. Is screwed into the core post through the mounting member. Thereby, the decorative cover member is fixed to the core column.
