    • The present invention provides a steel frame beam-reinforcing metal fixture that is capable of recovering the full strength of a steel frame beam to a greater extent than a conventional steel frame beam-reinforcing metal fixture for an S structure. A steel frame beam-reinforcing metal fixture is substantially fitted to a web opening in an SRC beam. An outer peripheral portion of the steel frame beam-reinforcing metal fixture is fillet-welded to a steel frame beam web. The axial length of the steel frame beam-reinforcing metal fixture is between 0.5 and 200.0 times the thickness thereof in the radial direction. Furthermore, in the steel frame beam-reinforcing metal fixture, a length from one end side of the steel frame beam web to one end of the outer peripheral portion and a length from the other end side of the steel frame beam web to the other end of the outer peripheral portion are each at least 0.7 times the thickness of the steel frame beam web.
    • 本发明提供一种钢框架梁加强金属夹具,其能够比用于S结构的常规钢框架梁加强金属夹具更大程度地恢复钢框架梁的全部强度。 钢框架梁加强金属夹具基本上装配到SRC梁中的卷筒纸开口上。 钢框架梁加强金属固定件的外周部分被圆角焊接到钢框梁梁。 钢框架梁加强金属夹具的轴向长度在径向的0.5至200.0倍之间。 此外,在钢框架梁加强用金属固定件中,从钢框梁梁的一端侧到外周部的一端的长度以及从钢框梁梁的另一端侧到另一端的长度 的外周边部分的厚度分别为钢框架梁腹板的厚度的至少0.7倍。

    • A protective tube for a thermocouple for measuring the temperature of molten metal, comprising two layers, an inner layer being made of a silicon nitride or sialon ceramic having a bending strength of 50 kg/mm.sup.2 or more, a density of 90% or more based on a theoretical density and a thermal shock temperature .DELTA.T of 400.degree. C. or more, and an outer layer being formed on the silicon nitride or sialon ceramic and containing BN and SiO.sub.2. The silicon nitride of sialon ceramic comprises 70 weight % or more of Si.sub.3 N.sub.4 having 65 weight % or more of an .alpha.-phase content, 20 weight % or less of one or more oxides of elements of Group IIIa of the Periodic Table, 20 weight % or less of Al.sub.2 O.sub.3, and optionally 15 weight % or less of AlN or AlN solid solution, and the outer layer is composed mainly of BN-SiO.sub.2 -Al.sub.2 O.sub.3 -Y.sub.2 O.sub.3. This protective tube is produced by coating ceramic powder comprising BN and SiO.sub.2 before sintering. This protective tube can enjoy an extremely long life.
