Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a centrifugally formed concrete column whose surface is provided with decorative tiles.

[Conventional technology]

To decorate a concrete building or a concrete part of a building with tiles, the tiles are generally pasted with mortar onto the surface of the concrete that has already hardened. The adhesion of the tiles may be insufficient and the tiles may peel off.
Another problem is that construction takes time and effort.

In some cases, a large number of tiles are glued together to a mortar plate, installed in a formwork, reinforcing bars are placed inside, and concrete is poured to form a concrete surface decorated with tiles.
It is necessary to manufacture in advance a large number of tiles glued together on a mortar plate, and in addition, it is necessary to attach them to the formwork at the construction site, which increases the number of man-hours and the construction cost due to the mortar mentioned above. There is a problem that it costs more than installing tiles.

There is also a method of gluing a large number of tiles together to a mortar plate and attaching them to the concrete surface with bolts, but this method has the problem that the decorative nuts are exposed on the surface of the tiles.

[Problem to be solved by the invention]

An object of the present invention is to provide a tiled decorative concrete column in which tiles are firmly fixed to the surface of the concrete column more easily and inexpensively than any of the above-mentioned methods.

[Means to solve the problem]

The present invention provides a tile decorative concrete column body in which a centrifugally formed concrete column body is integrally formed directly on the back surface of a decorative tile, as a means for solving the problem.

[Effect]

Since the concrete on the back side of the tile is solidified while being compressed to the tile by centrifugal force, the adhesive strength between the concrete and tile is stronger than that of any conventional structure, and the tile does not peel off at all. You get what you don't have. Furthermore, since it is only necessary to arrange the tiles on the inner surface of the mold and centrifugally mold the concrete, the labor required to form a mortar layer, which is an intermediate layer in the conventional method, is not required, and the manufacturing cost is accordingly reduced.

〔Example〕

To manufacture the columnar body of the present invention, a conventionally used formwork in the form of a square or cylindrical column divided into two in the longitudinal direction can be used as is. Tiles can be made by pasting paper on the surface of many tiles, or by lining up many tiles, pouring plastic onto the surface, and pasting a plastic sheet so that the front side of the tile faces the inner surface of the formwork. Then, fix it to the inner surface of the formwork with an adhesive sheet or tape. If the tile is thick, fix it with bolts from outside the formwork to screws fixed to paper or plastic to prevent it from falling off the inside of the formwork due to vibrations when moving the formwork. Reinforcing bars are placed in the formwork with tiles attached to its inner surface, as in the past, and concrete is poured into the back of the tiles and centrifugally compacted. The formwork is removed from the concrete that has been cured with steam and the paper or plastic sheets are peeled off to create a product, which is then transported to a construction site and used as columns, beams, etc. The reinforcing bars placed inside the concrete column may remain untensioned or may be tensioned to prestress the concrete.

〔Effect of the invention〕

According to the column of the present invention, the concrete of the main body is bonded directly to the back surface of the tile by centrifugal force, without using a mortar layer, so it has much better bonding strength than conventional tiles and is cheaper to install. We can provide decorative concrete columns.
