Abstract: A pipe joint is formed using a gasket made of coextruded materials of different durometer hardnesses. The gasket includes a relatively soft, thermoplastic elasomeric sealing portion joined to a harder, plastic substrate on one side of the substrate, usually on the outer circumference of the substrate. The substrate may include stiffening regions axially spaced apart from one another and on opposite axial sides of the softer material. The inner circumference of the gasket (if the softer sealing portion is on the outer circumference) may have annular ridges spaced axially from one another to engage shoulders in one of the pipes of the joint to limit axial displacement of the gasket. The gasket, because of its relatively hard substrate, will not collapse into a groove in the pipe defined by the shoulders, thereby reducing the amount of gasket material required by a typical recess joint. The annular ridges may be coextruded of the same material used for the elastomeric sealing portion, allowing both sides of the gasket to form a seal, thus also permitting the gasket to be useful in single offset joints.

Abstract translation: 使用由不同硬度的共挤出材料制成的垫圈形成管接头。 垫圈包括相对柔软的热塑性弹性密封部分，其连接到基底一侧上较硬的塑料基底，通常在基底的外圆周上。 衬底可以包括彼此轴向间隔开并且在较软材料的相对轴向侧上的加强区域。 垫圈的内周（如果较软的密封部分在外周上）可具有彼此轴向间隔开的环形脊，以接合接头的一个管中的肩部以限制垫圈的轴向位移。 垫圈由于其相对较硬的基底而不会塌陷在由肩部限定的管中的槽中，从而减少了典型的凹陷接头所需的垫圈材料的数量。 环形脊可以与用于弹性体密封部分的相同材料共挤出，允许垫圈的两侧形成密封，从而也允许垫圈可用于单个偏移接头。

Abstract: A coupler member for use with precast concrete segmental structures having a first duct, a first coupler member extending over and around an exterior surface of the first duct and having a seat opening adjacent an end of the first duct, a second duct, a second coupler member extending over and around an exterior surface of the second duct and a seat opening adjacent to an end of the second duct, and gasket received in the seats of the first and second coupler members. An external seal is affixed to an opposite end of the first coupler member and affixed to an exterior surface of the first duct. The seats of the first and second coupler members have slots facing one another. The gasket is received within these slots. The gasket has a tapered outer surface suitable for liquid-tight abutment against an inner surface of one of the slots.

Abstract: A coupler apparatus for use with tendon-receiving duct in a segmental precast concrete structure including a coupler body having an interior passageway for receiving the duct therein. The coupler body has a generally U-shaped channel formed at one end thereof. The coupler element has a connector element formed on interior thereof adjacent one end of the coupler body so as to allow the coupler element to receive a variety of implements for the formation of the precast concrete segment.
