摘要： A clamp fitment includes a pair of holding members each capable of clamping a pipe section, a coupler mounted between both the holding members for relatively rotatably but unseparatably coupling the holding members, and a lock mechanism mounted between both the holding members for restraining the relative rotation of the holding members at any time in positions in which the pipe sections clamped in the holding members intersect each other at right angles. The single clamp fitment for connecting the pipe sections can be used properly as either of "swivel type" in which the angle of intersection of the pipe sections can be freely selected and "orthogonal type" for unifying the pipe sections in a square fashion. This eliminates the need for a worker to carry two kinds of clamp fitments to a working field, leading to simplified handling and management of the clamp fitment.
摘要翻译：夹具配件包括：一对保持构件，每个保持构件能够夹持管段，联接器安装在两个保持构件之间，用于相对可旋转但不可分离地联接保持构件;以及锁定机构，其安装在两个保持构件之间用于限制相对旋转在夹持在保持构件中的管段彼此直角相交的位置处的任何时间保持构件。用于连接管段的单个夹具可以适当地用于可自由选择管段的相交角的“旋转式”，用于以正方形统一管段的“正交型”。这样就不需要工人将两种夹具装配到工作现场，从而简化了夹紧装置的处理和管理。

摘要： A nut adapted to disengage with a threaded bolt, the nut comprising a base portion integrally formed to a top portion. The nut includes a bore positioned along a central axis through the base portion and the top portion, wherein the top portion is tapered between circumference of the base portion and the bore of the top portion. The tapering is at an angle between 0° to 45° relative to the diameter of the base portion; the base portion comprises at least two cavities, wherein the at least two cavities extend vertically into the base portion.

摘要： A scaffolding tube clamp having a pair of body portions defining a top and a base that are hinged together and receivable about a scaffolding tube. A rotatable bolt is received through a hole in the top a hole in the base portion. The bolt has a lower end with engagement means to releasably secure the bolt to the base. The bolt's head has a lower surface that is engageable with a surface on the top. The lower surface of the head, and the surface of the top that is engaged thereby, have complimentary ramped configurations such that when the bolt is rotated the ramps engage, resulting in the ramps moving the top toward the base. In an alternate embodiment the bolt is threaded with two sets of threads that have different diameters and different pitches and that are threadably received within the holes in the top and bottom.

摘要： A clamp for scaffolding and temporary building and similarly acting fittings in which the curvatures of the pipe carrier and the pipe holder forming the clamp for receiving and holding the pipes are determined at a substantially intermediate value among the curvatures of the pipes of different diameters and a bolt embracer provided at the free end of the pipe holder is substantially directed to a radial direction of the circle formed by the pipe carrier and the pipe holder of the clamp, thereby averting the nut from slipping off the bolt embracer and securing a positive clamping effect.
