Components and uses for robust thread clamping device

摘要

The present invention relates to a thread clamping device including a plurality of movable nut segments around a threaded rod, and spring members flexibly holding the segments against the rod. The thread clamping device has a structure adapted to accommodate substantially planar outer surfaces of the nut segments engaging planar surfaces of the end housing of the device, leading to a more robust device and improved performance. Such a thread clamping device can advantageously be used as a component of a self-adjusting shrinkage compensation device, a coupler for threaded rods, hold-downs, among other uses. Various embodiments of the thread clamping device include a multi nut configuration, a quick release embodiment, and embodiments including mechanical or magnetic clip attachments.

主权项

1. A nut segment suited for use as component of a ratcheting thread clamping device comprising:
a threaded inner surface on an inner side of said ratcheting thread clamping device suited for engaging a threaded rod; and, a substantially planar inner sloping segment surface on said inner side of a first end of said nut segment; and, a substantially planar outer segment surface on an outer side of a second, opposite end of said nut segment; and, at least one segment spring grove; and, wherein said substantially planar inner sloping segment surface and said substantially planar outer segment surface lie in substantially parallel planes.
