Description

The present invention relates to a louver provided mainly on the outside of a building, a hollow cylindrical tile used for the louver, a firing method and a manufacturing method of the hollow cylindrical tile.

As a louver provided mainly on the outside of the building, hollow cylindrical tiles installed in parallel have come to be used, and in the installed state, mounting brackets and support bars provided on the columns are penetrated by the hollow cylindrical tiles. The through-holes were filled with foamed resin so as not to drop the hollow cylindrical tile fragments that were inserted into the holes or damaged by foreign object collision.
In this mounted state, the inner surface of the through-hole was usually a flat surface, so that it could not be firmly attached to the support column or the adhesiveness with the foamed resin was not sufficient.

As for the method of firing the hollow cylindrical tile, the plate tile is fired by placing it on a refractory shelf board, or the large-diameter hollow earth tube is fired independently.
The hollow cylindrical tile used for the louver requires a beautiful fired surface, and when placed on the shelf board and fired, the outer surface of the hollow tubular tile is damaged or defective due to contact with the shelf board. was there.
In addition, since the hollow cylindrical tile has a relatively small diameter, unlike a clay pipe, it cannot be fired independently.

We do not conduct prior art searches at the research and development stage or application stage, and do not know the prior art documents to be described.

The present invention provides a louver, a hollow cylindrical tile, a firing method thereof, and a manufacturing method thereof, in which a hollow cylindrical tile of a constructed louver is firmly attached to a column, or the outer surface is beautifully finished to reduce defective products. It is something to be done.

The present invention is based on the above prior art, and in view of the problem that there is a point to be improved in the fitting property and fixing property with the mounting bracket and foamed resin at the time of construction, the through hole provided in the longitudinal direction of the hollow cylindrical tile A hollow cylindrical tile provided with a groove in the longitudinal direction on its inner surface is used for the louver, and a convex portion is provided at the tip of the mounting bracket provided on the support column, and the convex portion of the mounting bracket and the hollow cylindrical tile are recessed. By engaging the groove and filling the through hole and the recessed groove of the hollow cylindrical tile with the foamed resin, the recessed groove and the mounting bracket or the foamed resin are engaged or brought into close contact with each other to solve the above problems. To do.

In addition, in view of the fact that the outer surface could not be baked neatly, the support rod body was passed through the through hole in a protruding state at both ends, and both the protruding both ends of the support rod body were placed on a support standing on the carriage, and the tile By firing the outer surface of the substrate in an aerial support without contact, it is beautifully fired in a non-contact manner with the carriage and the like, and further, the groove is formed as a hot air space on the inner surface provided with the groove and the contact surface of the support bar. By forming and firing, the above-mentioned problems are solved by firing without preventing welding or the like.

In short, the present invention is a hollow cylindrical tile provided with a through hole in the longitudinal direction, and a concave groove is provided in the longitudinal direction on the inner surface forming the through hole, so that the concave groove is engaged and fixed as described later. It can be used as a foothold to improve the construction state, and can be baked neatly by reducing the area or circulating hot air.

A louver in which a plurality of hollow cylindrical tiles are installed at fixed intervals on a support column, and the hollow cylindrical tile is formed by providing a groove in the longitudinal direction on the inner surface forming a through hole. A convex part is provided at the tip, and the convex part of the mounting bracket is engaged with the concave groove of the hollow cylindrical tile, so that the hollow cylindrical tile is firmly fixed to the mounting bracket of the support column and the displacement due to strong winds is prevented. Wind resistance can be prevented, and the hollow cylindrical tiles are filled with foamed resin in the through-holes and concave grooves. Thus, even if the hollow cylindrical tile is broken or damaged, the fragments can be prevented from falling.

A method of firing a tile body of a hollow cylindrical tile having a through hole in the longitudinal direction, wherein a support rod is passed through the through hole in a protruding state at both ends, so that the tile base is supported in the longitudinal direction. It is possible to prevent the deformation of the support rod body, and both ends of the support bar are placed on a support standing on the carriage so that the outer surface of the tile base is aerial supported in a non-contact manner and fired. The substrate is supported internally, and the outer surface is not in contact with any cart, support, etc., and the outer surface can be a beautiful fired surface.

A method of firing a hollow green tile tile body in which a groove is provided in the longitudinal direction on an inner surface forming a through hole, and the groove is formed into a hot air space on the contact surface between the inner surface and the support rod body and fired. As a result, the inner surface and the support rod are not in full contact with each other in the concave groove, so that the stress due to the difference in thermal expansion can be reduced, and the contact surface is divided by the concave groove, or the contact area is reduced. It is possible to improve adhesion and prevention of welding, and further, it is possible to improve the firing state by circulating hot air in the groove space.

Using a wet tile extrusion molding device that has a concave groove forming convex part and a through hole formed in the center of the base, a concave groove is formed in the longitudinal direction on the inner surface that forms the through hole. However, since the extrusion body of the endless hollow cylindrical tile was extruded, the improvement of the extrusion machine used in the folding screen folding tile (corner tile with a ridge line in the longitudinal direction) of the wet process It is possible to stably extrude an endless extruded substrate, and it is only necessary to improve the part of the die.
