    摘要: The invention relates to an improved joint structure used for jointing steel pipe pile pieces. The lower pile piece is provided with a stopper member which is secured on the inner wall of the pile at a position slightly lower than the joint and edge portion thereof and whose upper surface has an angle of inclination under 90*. The upper pile piece is provided with a joint metal piece which is secured on the inner wall of the pile piece has a straight portion and a reduced diameter portion and whose edge is cut to an angle so that in the normal engaging positions the edge comes into close contact with the inclined surface of the associated stopper member, thus preventing the phenomena of sideslipping between the upper and lower pile pieces. The band is fit on either the upper or lower pile pieces (preferably on the upper pile piece), serving as a guide for the welding device that travel along the outer periphery of the pile.

    摘要: The longitudinal ends or edges of a large plate composed of a plurality of unit plates welded together are not uniform or even and therefore the large plate cannot readily be utilized in that condition. In other words, the uneven portions on both ends of such a large plate must be cut to produce parallel ends. A cutting apparatus for large plates is provided, which mainly comprises a pair of rails disposed along the ends of a large plate and extending in the longitudinal direction thereof, a pair of cutting machines mounted on the rails to travel thereon, and a deviation detector for detecting the amount of deviation of position of a stopped large plate, whereby in accordance with the value of a detected deviation, the two rails are rotated in a parallel relation over the surface of the large plate to determine the cutting lines along the ends of the large plate, and the cutting devices are then brought into operation to remove the desired amount from both ends of the plate to produce the parallel ends.
