Abstract: A structural member includes a body having a first surface, a second surface, and an end surface at an end portion of the structural member. The end portion of the structural member includes a root protrusion extending radially outward from the second surface of the structural member along a root protrusion radius to an outer end of the root protrusion to define a root protrusion height extending from the second surface of the structural member to the outer end of the root protrusion. The root protrusion further includes a root protrusion width extending between an inner edge and an outer edge of the outer end of the root protrusion. The root protrusion radius, the root protrusion height, and the root protrusion width are configured to define a stress protected weld root region isolated beyond and away from a root stress flow path propagated through the body of the structural member.

Abstract: An apparatus for supporting a backing member in an enclosed structure is disclosed. The enclosed structure includes a first plate defining an opening therethrough. The apparatus is configured to be disposed within the enclosed structure. The apparatus includes a clamp member and a support member configured to rotatably support the clamp member. The clamp member is rotatable about a rotation axis defined by the support member. The support member is further configured to abut a second plate spaced apart from the first plate. The clamp member is configured to be moved along the rotation axis relative to the support member and bias the backing member to contact with the first plate along the opening.
Abstract translation: 公开了一种用于支撑封闭结构中的背衬构件的装置。 封闭结构包括限定穿过其中的开口的第一板。 该装置被配置为设置在封闭结构内。 该装置包括夹紧构件和构造成可旋转地支撑夹紧构件的支撑构件。 夹持构件可围绕由支撑构件限定的旋转轴线旋转。 支撑构件进一步构造成抵靠与第一板间隔开的第二板。 夹紧构件被构造成相对于支撑构件沿着旋转轴线移动并且偏压背衬构件以沿着开口与第一板接触。
