[Industrial applications]

 It concerns building materials.

[0002]

[Prior art]

 Originally, ceramics like Setomono were fragile and fragile, so they had many advantages and were shunned. In other words, it is resistant to fire, resistant to snow and snow, not bite by rats, has good insulation properties, but has the disadvantage that it is fragile and has poor impact resistance, so its use is extremely limited. is there. In order to compensate for the shortcomings, firing at high temperatures and applying glazes have been tried in various ways, but were insufficient. Therefore, we strengthened ceramic insulation and soundproofing blocks by inserting stainless steel wires in the walls. For the circular pipe, we prepared two large and small circular pipes, inserted a small circular pipe into the large circular pipe, put glaze and stainless steel wire between them, fired at high temperature, and strengthened the circular pipe. There was, however, the operation and labor was difficult.

[Problems to be solved by the invention]

 Ceramic tubes had many advantages, but their use was limited due to their poor impact resistance and brittleness. Many attempts have been made to solve the shortcomings, but they have been difficult. If the disadvantages of ceramic tubes can be compensated for even a little, their applications should be expanded. I once heard about a ceramic pipe coming out of the ruins of Bombay in Italy, but it is still possible to drain water. Ceramics are strong against wind and snow.

[Means for solving the problem]

 We repeated various trials and errors on how to strengthen a ceramic with low impact resistance. The ceramic cracked by a slight impact and easily separated to the right and left, so I put a hard streak on the left and right and tried various ways to attach it with a strong glue. When I put the metal in the material, it cracked in the middle of drying, and when fired it fell apart and there was no help for it. Therefore, a hole is made in the material, unglazed first, and stainless steel wire and glaze are put in the hole. Then, it is fired at a high temperature. The glaze melts and attaches the ceramic material to the stainless steel. The ceramic material and stainless steel have different expansion and contraction rates, but the glaze serves as a buffer and does not crack, so they can interact well. And the strength of stainless steel adds to the strength of the ceramic tube.

In the case of a ceramic circular tube, a small circular or square elongated hole is first formed in the wall of a circular tube made of a material. (Fig. 1) And this is unglazed. Then, when the tube is unglazed, stainless steel wire and glaze are put into the elongated holes. Then, it is fired at a high temperature. Then, the glaze melts and attaches the stainless wire and ceramic material, and the sisters and tubes increase in hardness and become stronger. It is just as strong as a boned muscle. Similarly, reinforced bricks can be made by drilling several small holes in a brick-shaped square ceramic material, drying and unglazing, then putting stainless steel wire and glaze in the small holes and firing at high temperature. (FIG. 4)

【Example】

 First, the material is put into a mold of a clay extruder and a circular tube is extruded. At that time, a circular or square hole is made in the wall of the circular tube. The circular pipe is a circular pipe having an inner diameter of 8 cm and an outer diameter of 12 cm, and a large number of circular holes having a diameter of 1.5 mm are formed in a wall having a thickness of 2 cm. And this is dried unglazed. When unglazing is completed, a 0.5 mm diameter stainless steel wire and glaze are placed in the elongated hole in the wall of the tube. This is then fired at high temperature to complete it.

[0007]

[Effect of the invention]

 Originally, ceramic products were fragile and poor in impact resistance, but the products of the present invention were considerably stronger and improved in impact resistance considerably. The applications are expected to expand considerably. Fabrication is simple, cheap and economical.
