Titanium Alloy of Iron Corporation in Japan is used in Maintenance Project

In the preservation and repair works of Shimizu temple in yinyushan, Japan (located in Kyoto City, hereinafter referred to as Shimizu Temple), super tix, a unique titanium alloy of Japan Iron Corporation, is adopted ® 51af is a part of structural reinforcing material. After the West cocoon warehouse of Fugang silk factory, Qingshui temple, which is both a world heritage and a national treasure, is the second building using titanium products.

The preservation and repair of the main hall of Qingshui temple is entrusted by Qingshui temple to the cultural property protection section of the Education Department of Kyoto Prefecture, and the seismic evaluation is in the charge of jiangjiri architectural structure design office. This preservation and repair project mainly focuses on repairing the damaged parts such as the roof and stage board, and taking measures to improve the seismic resistance, such as setting a winch hanging on the inclined foundation under the floor of the front half of the main hall to strengthen the connection between parts. Strengthening parts must reach the durability of hundreds of years. Therefore, it is necessary to use materials with good durability. This time, cabkoma rope rod produced by Komatsu matere company is used for the rope, and the parts of hardware connecting it with the wood on the beam - bearing connecting rod and large-size bolt are made of high-strength titanium alloy super tix ® 51AF。 This is because the alloy has unparalleled corrosion resistance among practical metals, and its specific strength is 2.3 times that of structural ordinary steel (S45C), and its fatigue resistance is about 3 times that of stainless steel (SUS304).

The super tix of Japan iron and Steel Co., Ltd ® 51af raw materials are processed into connecting rods and large-size bolts. After Komatsu matere purchased them, cabkoma rope rod is joined with titanium parts in the company, made into reinforcement parts, and constructed on site. In addition, the hardware at the joint with the wooden beam adopts the stainless steel section steel made in Japan and the nssc270 nut produced by Nippon Steel.

So far, titanium products made by Japanese iron have been used in historical buildings, such as the Sutra building of Shanguang temple and the renovation project of the West cocoon warehouse of the world heritage Fukuoka silk factory. Super tix unique to Nippon Steel is adopted ® 51af alloy screw and connecting rod is the first time. From the point of view of reducing life cycle costs and improving the life of social infrastructure, Nippon Steel intends to expand the application of titanium products in seismic reinforcement projects of historical buildings such as world heritage sites, national treasures and temples and shrines of important cultural properties.

Nippon Steel has always been pursuing the world's highest and super technology, and continues to contribute to social development by carrying out activities consistent with the sustainable development goal of the United Nations - strengthening the protection and preservation of world cultural heritage and natural heritage.
