摘要： PROBLEM TO BE SOLVED: To provide a load carrying test method using a double vane type pile and capable of conducting an indentation test and a pullout test with the spiral vanes of the double vane type pile arranged in a bearing stratum and to provide its device. SOLUTION: A cylinder 18 is arranged in the pile 3 having a vane 2 along the outer periphery near the tip section of an outer tube 1, and the tip section of the cylinder 18 is arranged protrusively from the outer tube 1. A vane 21 is provided along the outer periphery near the tip section of the cylinder 18, and the cylinder 18 is rotatively pressed into the ground together with the pile 3, with the rotation and the upward shift of the cylinder 18 constrained against the pile 3. The vanes 2 and 21 are allowed to intrude into the bearing stratum A, then the pile 3 and the cylinder 18 are relatively separated in the vertical direction by a jack to conduct the indentation test or the pullout test of the pile.

摘要： PROBLEM TO BE SOLVED: To provide a portable tension measuring device capable of lightening the whole device, and improving convenience of carriage, measurement workability, and precision security. SOLUTION: A pair of support arms 2, 2 is integrated decomposably on a reaction frame body 1a, and the reaction frame body 1a is two-point supported on a tension material W by each support arm. A gate-shaped frame 3 is integrated movably on the reaction frame body 1a. The gate-shaped frame 3 is supported on the center part between two-point supports of the tension material by each support arm 2, and pressed by a press mechanism 4 against a tension T of the tension material. The press mechanism 4 has a moving shaft 44 moving in the rotation axis direction by rotation of a rotational internal thread member 41, and its head part 44a is allowed to abut on the reaction frame body, and the gate-shaped frame 3 is moved against the tension of the tension material W by a reaction resulting from rotation of the rotational internal thread member 41, and a load P and a displacement δ relative to the tension material W are made readable by a load cell 5 and a dial gage 6 integrated in the reaction frame body.

摘要： PURPOSE:To enable a belt-like metallic sheet to be bent with high precision. CONSTITUTION:A male die 4 is structured by providing an engaging flanges 3, at spaces apart slightly wider than a belt-like metallic sheet 2, on the surface side at both ends of the male die body 1 that is provided with a surface circular- arcuate in the front part; the belt-like metallic sheet 2 is fitted in a groove formed by each engaging flange 3 in the male die 4 and the male die body 1; then, the male die 4 and a female die 5 arranged in parallel with it are moved so as to be relatively close to each other; and finally, bending is performed on the belt-like sheet material 2.
