    • A retrofit system for providing a load indicator on a foundation bolt. The system includes a fastener having a fastener head, gauge length and central fastener bore in the gauge length and head. A datum rod is anchored in the central bore with a free datum rod being moveable longitudinally relative to the fastener head during elongation of the fastener gauge length. An internally threaded fastener portion below the central fastener bore is configured to thread over a foundation bolt. A compression sleeve positioned over the foundation bolt is configured to receive the load indicating fastener therein and to bear the compressive forces of the fastening. Elongation of the gauge length as the fastener is tightened onto the stud is manifest as displacement of the datum rod end, which displacement is measured to provide an indication of fastener loading.
    • 用于在基础螺栓上提供负载指示器的改进系统。 该系统包括紧固件,该紧固件具有紧固件头部,标距长度和标距长度和头部中的中心紧固件孔。 基准杆被锚定在中心孔中,其中一个自由基准杆可以在紧固件标距的伸长期间相对于紧固件头纵向移动。 在中心紧固件孔下方的内螺纹紧固件部分构造成在基础螺栓上螺纹连接。 定位在基础螺栓上方的压缩套筒构造成在其中容纳负载指示紧固件并承受紧固件的压缩力。 当紧固件紧固到螺柱上时,标距长度的缩短表现为基准杆端的位移,该位移被测量以提供紧固件加载的指示。

    • A method and apparatus for repairing a casting in a cold metal repair process includes a plurality of drilling fixtures which facilitate the creation of one or more lock receiving recesses positioned generally transverse to the casting crack. The lock receiving recesses are formed of a single sized circular bore combination having alternating double and single circular portions to maximize strength. A plurality of correspondingly configured metal locks are inserted into the lock receiving recesses to provide transverse metal locks drawing the casting portions on each side of the crack together. A plurality of threaded bores are formed along the remainder of the casting crack in overlapping spacing which receive a corresponding plurality of stitching pins. The stitching pins each define threaded shaft portions having pointed ends and undersized major pitch diameter threads adjacent the pointed ends. A frusto-conical shoulder is formed on the opposite end of the threaded shaft and a break off drive head is coupled to the frustro-conical shoulder by a break off groove structure. When the stitching pins are inserted into their respective threaded bores, the undersized major pitch thread portions facilitate the threading the pin into the threaded bores. The pointed ends of the stitching pins provide complete filling of the threaded bores while the frustro-conical shoulder portions are operative to crush the first few threads of the threaded bores to enhance the seal obtained.
    • 用于在冷金属修复过程中修复铸件的方法和装置包括多个钻孔固定装置,其有助于产生大致横向于铸造裂缝定位的一个或多个锁定容纳凹部。 锁接收凹部由具有交替的双和单个圆形部分的单个尺寸的圆形孔组合形成,以最大化强度。 多个对应配置的金属锁被插入到锁定容纳凹槽中,以提供横向金属锁,将裂缝的每一侧的铸造部分拉在一起。 沿着铸造裂纹的其余部分以重叠的间隔形成多个螺纹孔,其接收相应的多个针脚。 缝合销各自限定具有尖端的螺纹轴部分和与尖端相邻的尺寸较小的大直径螺纹。 在螺纹轴的相对端上形成有截头圆锥形的肩部,通过断裂槽结构将断开的驱动头连接到截头锥形的肩部。 当缝合销插入其各自的螺纹孔中时,尺寸较小的主间距螺纹部分便于将销螺纹穿入螺纹孔。 缝合销的尖端提供螺纹孔的完全填充,而截头锥形肩部可操作地压碎螺纹孔的前几个螺纹以增强所获得的密封。
