Annular prestress tensioning structure of LNG tank body and method for setting number of segments of annular prestress tensioning structure
The invention provides an LNG tank body circumferential prestress tension structure and a segmentation number setting method thereof. The LNG tank body circumferential prestress tension structure comprises an LNG tank body wall, a supporting end, a pre-buried cantilever steel beam, a circumferential prestress steel strand bundle and a jack. A plurality of supporting ends are evenly arranged on the periphery of the LNG tank body wall, and the embedded cantilever steel beams are connected with the supporting ends. And the circumferential prestressed steel strand bundle is arranged in the tank body wall and the supporting end. The jack is arranged on the pre-buried cantilever steel beam and used for tensioning the circumferential prestress steel strand bundle. The invention further provides a method for setting the number of the annular prestress sections of the LNG tank body. The method comprises the steps that (1) the length C of the annular prestress steel strand bundle is determined according to the circular radius R of the LNG tank body; 2) determining the length l of the segmented arc-shaped steel strand bundle of the circumferential prestressed steel strand bundle according to the standard that the concrete of the LNG tank body wall does not have tensile stress, and 3) determining the number n of the segments of the circumferential prestressed steel strand bundle.
本发明提供一种LNG罐体环向预应力张拉结构及其分段数量设置方法，包括：LNG罐体墙、支撑端、预埋悬臂钢梁、环向预应力钢绞线束、千斤顶。LNG罐体墙四周均匀布置若干个支撑端，预埋悬臂钢梁与支撑端连接。环向预应力钢绞线束布置在罐体墙和支撑端内。千斤顶设置在预埋悬臂钢梁上，用于张拉环向预应力钢绞线束。本发明还提供了LNG罐体环向预应力分段数量的设置方法：1）根据LNG罐体的圆形半径R确定环向预应力钢绞线束的长度C，；2）根据LNG罐体墙的混凝土不出现拉应力的标准确定环向预应力钢绞线束的分段的圆弧形钢绞线束长度l；3）根据确定环向预应力钢绞线束的分段数n。
