摘要： PROBLEM TO BE SOLVED: To enhance the excavating accuracy (eliminating deviation from planned position) of an underground excavator by further improving a displace ment measuring device. SOLUTION: A bottom end of a measuring wire 1 is connected to an underground excavator 2, and the displacement of the wire 1 is measured above the ground in a displacement measuring device for measuring the position and displacement of the underground excavator 2. In this case, a main body section 20 having a function element for sending the measuring wire 1 while maintaining a certain tension and a control function element for calculating the position and/or displacement of the underground excavator 2 based on the displacement of wire measured and indicating the results on a display is separated from a detecting section 11 consisting of a function element measuring the displacement of the measuring wire 1 in the configuration. Both of them are combined together by installing a guide sheave 4 installed at a position directly above the detecting section 11 for measuring wire 1 taken out from the function element of the main body section 20.

摘要： PROBLEM TO BE SOLVED: To find a defect in measuring accuracy and quickly take countermeasures by measuring horizontal displacement and the angle of torsion by comparing calibrated displacement of a wire for displacement measurement by a calibrating device to the displacement in the horizontal direction of a wire for measuring displacement and by measuring horizontal displacement and the angle of torsion. SOLUTION: A calibrating equipment 3 capable of providing calibrated displacement in the horizontal direction for displacement measuring wire 2 by the quantity of setting is mounted on an upper end portion of an underground excavator 1, and the lower end portion of the displacement measuring wire 2 is connected to the device. The displacement measuring wire 2 is wound around a guide sieve 6 attached to an equipment frame 4 and suspended vertically downward, and detection means 8, 9 for displacement in horizontal direction are provided at two upper and lower places. Horizontal displacement of the displacement measuring wire 2 at the time when the underground excavator 1 has the level equal to the ground level is measured by using the calibrating device 3 and the result is used as a standard for excavation accuracy measurement thereafter. After this, it is compared to the results of measurement as required, and the horizontal displacement and the angle of torsion are determined, and the measured results of the excavation accuracy of underground excavator 1 are obtained. If the horizontal displacement and the angle of torsion have exceeded a preset control limit, the position and attitude of the underground excavator 1 are controlled and corrected and more accurate excavation work is carried out.

摘要： PROBLEM TO BE SOLVED: To correct the erection accuracy of a column (steel frame column) in a drive floor advance rise type building construction method. SOLUTION: One end of a tensile material 2 is fixed to a drive floor 1, the other end of it is fixed to an existing structural body 3 at an angle which produces a correction force roughly in the horizontal direction relative to the direction to correct column erection error, and the drive floor 1 is raised slightly in order to correct the erection error of a column 4 by using the resultant force of a proper tension generated in the tensile material 2 and the rising force of the drive floor 1 as a correction force. Then the column 4 is connected fixedly to a beam steel frame 5 of next upper floor. Because the vertical accuracy of multiple steel frame columns can be corrected at once through the drive floor, the number of cables used is not in proportion to the number of columns. It may be less, and also a lever block is not needed. Thus labor is less needed and, accordingly, the work period can be shortened.

摘要： PURPOSE:To embody a building work which is designed for all weather service and eliminates high elevation work. CONSTITUTION:An upper lock mechanism 6 and a lower lock mechanism 7 are formed with a load transmission member 8 and a lock member 9 respectively where the load transmission member 8 is formed with a load transmission member end 8a and a counter weight end 8b substantially in an inverted V shape. The lock member 9 is located directly over the load transmission member 8 and installed at the position at which the lock member comes in contact with a location which forcibly produces a rotary moment with the load transmission member 8. This construction eliminates any need for a load transfer jack and a lock jack and all sensors as well. Therefore, load transfer control is no longer required. The structure is extremely simplified so that dramatic cost reduction may be available due to reduction of equipment cost.
