摘要： PROBLEM TO BE SOLVED: To provide a rubber bearing and pile head structure capable of reducing a bending moment generated in the connecting part between an upper structure and a lower structure with a simple structure. SOLUTION: This structure comprises a protruding upper bearing part 11 fixed to the lower part of a footing 1, a recessed lower bearing part 12 fixed to the head part of a foundation pile 2, a columnar or cylindrical bearing rubber 13 consisting of a rubber elastic body excellent compression restorability, which is arranged between the upper bearing part 11 and the lower bearing part 12. The bearing rubber 13 supports the upper structure and absorbs a rotation around the axis. Further, a side receiving rubber 14 is arranged between the circumferential surface of the protruding part 11m of the upper baring part 11 and the inside surface of the recessed part 12m of the lower bearing part, whereby a horizontal force acting in an earthquake or the like is absorbed.

摘要： PROBLEM TO BE SOLVED: To provide a base isolating pile and a pile head unit which can reduce loads to the coupled part of a pile main body with a foundation slab and to a structure or the like by extending the period of input earthquake motion transmitted from the pile to the structure and which have no problems with maintenance. SOLUTION: A horizontal slide mechanism 5 comprising a ball bearing or the like is provided on the upper surface of a pile head so that a foundation slab 4 is horizontally slidably supported. A horizontal force transmitting member 2 made of a steel rod having a smaller flexural rigidity than a pile main body 1 is inserted into the hollow part of the pile head, and the bottom of the horizontal force transmitting member 2 is fixed inside the pile head using filling concrete 3 or the like. The top of the horizontal force transmitting member 2 is extended upward from the pile head by a predetermined length, and the horizontal force transmitting member 2 is driven into the foundation slab 4 to couple the pile main body 1 to the structure foundation slab 4.

摘要： PROBLEM TO BE SOLVED: To provide a press mechanism for suppressing variation of rolling load as smaller as possible at the time of joining steels having different thicknesses. SOLUTION: After facing a preceding thin steel 31 to the succeeding thick steel 32, the preceding steel 31 is put on the succeeding steel 32 and pressurization with a punch 13 is started. In the state where pressure welding is completed, the preceding steel 31 and the succeeding steel 32 are connected through joint surfaces 30 and also tapered surfaces 32a, 32a are formed on the succeeding thick steel 32. Then, the change in thickness becomes gentle, so the variation of the rolling load in the rolling of the next stage is reduced and break of the steel is effectively prevented.

摘要： PURPOSE: To improve the quality of the surface of plating and furthermore to improve the durability of a rolling bearing. CONSTITUTION: Excluding the time immediately after operation, a shaft 20 and the edge part of an axis 15 is disengaged. In this state, a support roll 9 rotates only by friction between a belt-like metallic sheet whose surface is subjected to plating treatment and its surface. Thus, the wear of a rolling bearing 13 reduces.

摘要： PURPOSE:To provide a device for smoothly charging raw material from an opening at the upper part of a cylindrical furnace without largely tilting the furnace. CONSTITUTION:(1) A raw material charging device in the cylindrical furnace is provided with a trough type vessel 1 having U-shaped cross section, a pushing- out plate 2 shifting from one end to the other end of the vessel along the inner periphery and mechanism (ball screw 4, etc.) for driving this pushing-out plate. (2) This device is provided with rollers arranged at the bottom part of the vessel 1 or the bottom part and the side parts. (3) Further, this device is provided with the roller and the pushing-out plate at the same time. As the raw material can be charged without largely inclining the raw material charging device, a little tilting of the furnace body may be enough. The raw material can be charged at high packing ratio without interfering with the attached equipment of the furnace.
