JP5082564B2 - Column base structure of independent column, column base construction method, and makeup base member of column base - Google Patents

Description

  The present invention relates to a column base structure and a column base construction method in the case where a makeup finish imitating a meteorite is applied to a column base of an independent column standing on an entrance porch, a piloti, a terrace or the like of a building, and the structure / The present invention relates to a makeup base member for a column base used in the method.

  When an independent column (a column that stands alone without a wall being connected to the surroundings) is erected on the entrance porch, piloti, etc., it is often constructed so that its column base is supported via a meteorite. However, simply placing a meteorite made of natural stone or concrete on the ground surface and standing an independent pillar on it will make it structurally vulnerable to horizontal force and lift. Then, after connecting the column base of an independent pillar to the foundation in the ground, the structure which performs the decorative finish imitating the meteorite around the column base part is proposed (for example, patent documents 1-3 etc.). .

  The column base structure described in Patent Document 1 is a resin concrete in which a column made of a square steel pipe is connected to the top end of a foundation buried in the ground and divided into about 2 to 4 around the column base. A cover material (decorative material) made from the side is fitted from the side to make a meteorite-like makeup finish.

In addition, the column base structures described in Patent Documents 2 and 3 have a through-hole formed at the center of a cast iron or aluminum die cast boulder (meteorite) having a truncated pyramid shape, and a column made of a square steel pipe The column base is connected to the foundation in the ground through the through hole.

  Since the column base structure described in Patent Documents 2 and 3 has to be built with the column base inserted in the through hole of the meteorite, it is difficult to perform the column adjustment and the connection work with the foundation. . In addition, if the top position of the foundation is close to the finished surface of the external floor, the meteorite will overlap the connecting part between the column base and the foundation, and the meteorite inserted in the pillar will interfere with the foundation. There is also a risk of hindering the connection work.

  On the other hand, since the column base structure described in Patent Document 1 is a structure in which a pillar-like decorative material is retrofitted to the column, the column erection work and the foundation are compared with the column base structures described in Patent Documents 2 and 3 above. It is easy to perform the connection work. However, since the cross-sectional shape of the decorative material is complicated, when natural stone or artificial stone is used for the decorative material, it takes time and effort to process it. In addition, since the decorative material made of natural stone or the like is heavy, there is room for improvement in the foundation structure and the like for positioning it accurately and stably supporting it.

  Furthermore, the column base structures described in Patent Documents 1 to 3 all use square steel pipes for the columns. However, when wood is used for the columns, the connection structure between the columns and the foundation also changes. It is necessary to consider the storage of meteorites.

  The present invention has been made in view of the circumstances as described above, and can be rationally constructed regardless of whether the material of the independent pillar is steel or wood, and a decorative material simulating a meteorite A column base structure of an independent column excellent in both design and workability that can be mounted accurately and stably, a column base construction method, and a makeup base member for the column base used in the structure and method It is.

The column base structure of the independent column according to the present invention is attached to the column base of the independent column connected to the foundation so that the column base cover that is formed into a cylinder by conjugating the halves surrounds the side surface of the column base. A makeup base skirt constituting a frustum-shaped frustum-shaped portion is attached to the side surface of the column base cover by conjugation between halves, and a cosmetic material receiver projecting outward is formed on the side surface of the makeup base skirt. In the state where the decorative material provided with a piece and formed of natural stone or artificial stone in a flat plate shape on the front and back is placed on the decorative material receiving piece, an adhesive is applied to the frustum-shaped portion of the makeup base skirt. It is characterized by being pasted through.

  In the present invention, the column base is configured by a cylindrical section having a uniform cross section integrally provided on a column base metal that connects an independent column made of wood and a foundation, or has a uniform cross section. It is comprised by the lower-end vicinity part of the independent pillar which consists of steel pipes.

  This column base structure can be constructed after the column is built. Since the decorative material is mounted on the decorative material receiving piece formed on the decorative base skirt and is adhered to the frustum-shaped portion with the hem expanded, positioning of the decorative material is easy and the holding state is also stable. Moreover, since the cross-sectional shape of the decorative material is simplified, even when natural stone or artificial stone is used as the decorative material, it is possible to reduce the labor and cost of processing the decorative material.

  Further, in the above-mentioned column base structure, the column base cover and the makeup base skirt are joined by shifting the alignment positions of the respective half halves around the axis of the independent column by 90 degrees. The mounting state of the base skirt is further improved.

The independent column column base construction method according to the present invention follows a rational construction procedure of the column base structure. That is, the lower end portion of the independent column is connected to the foundation located below the floor surface through appropriate connection means, and the column base of the uniform cross section provided on the independent column or a part of the connection means A column base cover that is cylindrical by conjugation between halves is attached and temporarily fixed to the column base, and a frustum-shaped part that is widened by conjugation between the halves is formed on the outer surface of the column base cover. The makeup base skirt to be formed is attached, and the column base cover and the makeup base skirt are fixed together by screwing on the side surface of the column base with a screw, and then the cosmetic base piece is formed by protruding from the outer surface of the makeup base skirt. The decorative material is placed on a frustum-shaped portion of a makeup base skirt with an adhesive in a state in which a decorative material formed of natural stone or artificial stone is formed into a flat plate shape on the front and back sides. The floor surface is finished at a position where the lower end of the material is hidden. According to this column base construction method, even when a heavy weight cosmetic material is used, it can be constructed efficiently and the cosmetic material can be attached with high accuracy.

A base material for a column base according to the present invention is a member optimized for carrying out the column base structure or the column base construction method, and is a half plate made of a thin metal plate material processed into a U-shape as viewed from above.
