摘要： PROBLEM TO BE SOLVED: To suppress a local deformation by forming gaps between the outer peripheral edge sections of diaphragms and the insides of connection sections, inserting the diaphragms into the gaps at multiple positions along the outer peripheral edge sections respectively, and inserting and holding the diaphragms at the connection sections. SOLUTION: Diaphragms 4 are mounted on diaphragm receiving members 6. Wedge members 5 are driven between the inner faces 2c of connection sections on the back side of beam flange weld sections connecting the flange sections 3a of beams 3 and the outer peripheral edge sections 4a of the diaphragms 4 respectively. The wedge members 5 and the outer peripheral edge sections 4a are connected by fillet welding, and the diaphragms 4 are closely inserted into the connection sections 2. The cross sectional deformation of the connection sections 2 is prevented against the compressive force and tensile force applied to the connection sections 2 of the beams 3. The diaphragms 4 easily inserted into the connection sections are fixed on the inner faces of the connection sections 2 by the wedge members 5, the cross sectional deformation of the connection sections 2 is prevented, and the rigidity of a frame can be maintained.

摘要： PURPOSE: To analyze a mechanism automatically without newly inputting restriction conditions by finding a maximum fulcrum reaction generated at a fulcrum from a specific expression when fulcrum reactions generated at respective fulcra of mechanism constituent members are found. CONSTITUTION: When the mechanism generate a certain acting force at a mechanism acting point D in a specific operation attitude, the mutual relation of fulcrum reactions that the respective fulcra 10 that the mechanism constituent members have is temporarily found by a mechanism analyzing means in a 1st process. Then, when an output mechanism having an output mechanism number A generates a maximum fulcrum reaction Fmax(A), a maximum fulcrum reaction Fm(b, A) generated at a fulcrum with a fulcrum number (b) is found in a 2nd process from the expression Fm(b, A)=F(b, N)×(Fmax(A)/F(A, N). In the equation, F(b, N) is the fulcrum reaction corresponding to the fulcrum number (b) which is found by the analysis of the 1st process, and F(A, N) is the fulcrum reaction generated at a fulcrum 10 to which an output mechanism displaying the maximum output Fmax (A) found by the analysis of the 1st process is connected.

摘要： PROBLEM TO BE SOLVED: To make the peripheral surface of a tire disk abutting on a carried body a smooth continuous surface by absorbing the thermal expansion in the peripheral direction produced in the tire disk by a slit to prevent the generation of a thermal stress and by eliminating the slit with abutting on broken sections opposed to each other of the slit when it is used. SOLUTION: A tire disk 13 is freely expanded in a peripheral direction by a slit 17 in a usage state of high temperature atmosphere. Since a distance L between broken sections 17a and 17b of a slit 17 which are opposed to each other is set in response to the amount of expansion produced in the tire disk 13 in a peripheral direction in a usage temperature, the thermal expansion is absorbed by the tire disk 13 to prevent the generation of a thermal stress. Since broken sections 17a, 17b of the slit 17 which are opposed to each other are put into contact with each other to eliminate the slit 17, the peripheral surface of the slit disk 13 becomes a smooth continuous surface.

摘要： PURPOSE:To obtain an estimation method in which the proof stress of a steel-pipe- pillar-beam jointed part using a long stiffner-type steel-pipe-pillar is estimated simply and properly by a method wherein the maximum proof stress of the steel-pipe- pillar-beam jointed part is computed by using a specific expression. CONSTITUTION:A long stiffner-type steel-pipe pillar is used as a steel-pipe pillar 100. The maximum proof stress Pcmax and the yield strength Pcy of a steel-pipe-pillar-beam jointed part are computed and estimated by Expression I and Expression II on the basis of the flange width Bf of a beam 2, the outside diameter Dp of a chopped part 1A, the pipe thickness (t) of a connection part 1B, a chopped-part-thickness increase amount hp=tp-t which has subtracted the pipe thickness (t) from the pipe thickness tp of the chopped part 1A, the wall-thickness center radius Rp of the chopped part 1A and a chopped-part excess length Lp which is smaller out of chopped-part excess lengths from both the upper and and the lower end of the beam 2 up to both the upper end and the lower end of the chopped part 1A. The radius Rp is a radius in a position which is at a distance of 1/2 of the pipe thickness tp of the chopped part 1A on the center side. In addition, sigmaY represents the criterion strength of the steel-pipe pillar, and X1 to X6 represent factors.
