IPC: B21B15/00
Filed: 1990-08-02
Abstract: PURPOSE:To obtain a quick and simple joining method by bringing each billet into contact on both end areas in the width direction, on one hand, cutting them in such a form that they have gap between both end areas, then, heating, pressing the respective estimated parts to be joined of the preceding and succeeding billets and expanding the joined area gradually. CONSTITUTION:The rear end part of the preceding sheet bar 1-a and the front end part of the succeeding sheet bar 1-b are cut by a drum shear 5 in the shape of a circular arc. Then, after both the respective areas on the rear end part of the leading sheet bar 1-a and the front end part of the succeeding sheet bar 1-b are abutted in a contact state, both end areas only are heated with a solenoid type induction coil. When the heating temperature has arrived at a prescribed temperature heating is stopped and both sheet bars are pressed by pinch rolls 3b and 3c. A joining allowance is expanded by this pressing force. The required time is reduced drastically.

Title: Controlling vibration of vibrating pile-driver
Inventor: ASHIDA YOSHIKI
IPC: E02D7/18
Filed: 1990-08-02
Abstract: PURPOSE:To enable execution under the minimum state of ground resistance by utilizing an actual vibrating-section vibration value and a soil quality data corrected based on the rate of execution of pile driving or pull-out and controlling vibrations. CONSTITUTION:When a vibrating pile-driver is operated, the vibration value of a vibrating section 3 detected by a vibration detector 8 is input to an arithmetic processor 10 through a signal conversion processor 9 and analyzed. When the vibration value of the vibrating section 3 computed by the analysis and the number of temporary vibrations input before the start of execution do not coincide, soil quality data are corrected and processed until both values agree. The optimum number of vibrating-section vibrations in which ground resistance values calculated from the vibration values of each section of a pile P are minimized is computed, and the actual number of the vibrating-section vibrations is controlled so as to coincide with the optimum number. Accordingly, a series of processing is repeated until the completion of execution, and control is also finished together with the completion of execution.
