Preload apparatus
| DWPI Title: Apparatus for providing preload to mated components in joint system, includes preload mechanism that has screw extends through aperture from first edge to second edge, and screw is removably secured to first edge or second edge of aperture |
| Abstract: An apparatus for providing a preload to mated pipes including a ring-shaped body formed by a sidewall and an attachment structure on a portion of the body. The ring-shaped body includes an aperture that extends through the sidewall. The attachment structure corresponds to an attachment portion of a pipe in the mated pipes and the attachment structure enables removable fastening of the body to the pipe. The apparatus may further include an adjustable preload mechanism that can be removably attached to the body to hold the body in a preloaded position. The preload mechanism can be adjusted to release a portion of the preload held by the body. |
| Use: Apparatus for providing preload to mated components in a joint system. |
| Advantage: The preload mechanism is adjusted to release a portion of the preload held by the body, so that the apparatus provides a preload to the mated pipes in an efficient manner. The apparatus is simple in structure, and manufactured in a cost effective manner. |
| Novelty: The apparatus includes a body that generates and store a preload, where the body has a sidewall and an aperture that extends through the sidewall. An attachment structure on an element of the body corresponds to an attachment element of a component in the mated components. An adjustable preload mechanism is attachable to the body to hold the body in a preloaded position. The aperture is defined by two edges, and the mechanism has a screw extending through the aperture from one edge to another edge. The screw is removably secured to one of the edges of the aperture. |
