摘要： PROBLEM TO BE SOLVED: To make the extra removing work of a concrete core unnecessary by a method wherein the concrete core developing through the boring with a core bit is discharged outside through the hollow part of the core bit and the hollow part of a drill shaft. SOLUTION: The core bit 14 of a boring machine is registered to a boring position on a concrete surface 20. After the settlement of the position of a trestle 1, the trestle 1 is bound with a temporary or regular anchor 31 to the concrete surface 20. Then, by fixing a waterstop through pressure bonding, an enclosedly structured coolant storage chamber 21 is completed. By utilizing the coolant storage chamber 21, a coolant is fed to the core bit 14 so as to start the boring of the concrete 20 with the core bit 14. A rotary shaft 4 and a drill shaft 15 are rotated by a driving motor 5. A driving part 3 and the core bit 14 are fed by patch by pitch by a level handle 25. The coolant in the coolant storage chamber 21 is sucked through a hose 24 and then discharged outside through a hollow part 16 or the like. Thus, the drawing work of a concrete core out of the core bit 14 is made unnecessary and the labor for a boring work can be reduced.

摘要： PROBLEM TO BE SOLVED: To reduce a dangerous work around a pile hole by joining steel-made pile-like materials serially in the vertical direction at an intrusion position by flash-butt welding by use of a feed mechanism formed by a frame part, a grip part and an actuator and simultaneously intruding the same in order in the ground. SOLUTION: A following steel-made pile-like material is hoisted and put in an opening 14 by a heavy hoist similarly to the preceding steel-made pile-like material, lowered until it reaches the position level of an upper frame part 6 of a device 1 so that the lower part of the steel-made pile-like material is opposite to the preceding steel-make pile-like material in the vertical direction, and gripped by a grip part 5 of the frame part 6. After that, the lower part of the following steel-made pile-like material is lowered by the frame part 6 to abut on the end faces of both steel-made pile-like materials. Subsequently, in a flash process in which by a welding means in which the grip parts 5 of the frame parts 6, 7 are taken as an electrode to be connected to a welding power supply, the abutting faces are fused by heating and then the abutting faces are pressed by the upper and lower frame parts 6, 7 to complete a joining process.

摘要： PROBLEM TO BE SOLVED: To provide a simple and low-cost device by applying a relative displacement of a specified amount to vibration frames arranged in parallel using an agitator means which converts the rotation of a servo motor to a horizontal displacement, allowing agitation with a small force. SOLUTION: A test body 4 such as a construction secondary member is so attached as to span vibration frames 1 and 1' suspended from an external frame 2, and the vibration frames 1 and 1' are applied with a horizontal 2-dimension relative displacement by an agitator means which converts the rotation of a servo motor 3 to a horizontal displacement, for a displacement follow-up performance-confirming test. When a lower-side rotary disc 13 is rotated by the servo motor 3, an upper-side rotary disc 12 connected with a chain 17 makes a horizontal relative eccentric circular movement (crank action) with a support axis 18 as a crank pin. The vibration frames 1 and 1' which is, positioned on the rotary disc 12, suspended from the external frame 2 with a suspending material 6 by four corners generate a horizontal 2-dimension vibration which is indicated by an arrow 19 as a synthetic movement.

摘要： PROBLEM TO BE SOLVED: To secure pressurizing at joining faces required for high quality joining and to improve joining precision after joining. SOLUTION: On the outer peripheral faces near the joining faces P1a, P2a of two joining members P1, P2, a non-moving pressing face 14a of a first press restriction fixture 13 and a moving pressing face 17 of a second pressing restriction fixture of a clamp device 10 are pressed in a state that the movement in the right angle direction of the pressing direction R of the portion near the joining faces of two joining members P1, P2 is restricted, and the joining faces of two joining members P1, P2 are thus strongly pressed to each other to be joined each other. Even in strongly pressing the joining faces to each other, this method prevents the deformation of buckling, etc., of the joining members.
