The invention provides a square-to-round trunk joint and a lofting method thereof, and relates to the field of joint lofting. The square-to-round trunk joint comprises four triangular parts and four fan-shaped parts which are alternately arranged, the bottom edges of the four triangular parts are sequentially connected to define a joint square opening, and the joint square opening is used for being connected with a square ventilation trunk in a matched mode. The arc sections of the four fan-shaped parts are sequentially connected to define a connector circular opening, and the connector circular opening is used for being connected with a circular ventilation trunk in a matched mode. The vertexes of the fan-shaped parts coincide with the intersection points of the bottom edges of the two adjacent triangular parts, the vertexes of the triangular parts coincide with the intersection points of the arc sections of the two adjacent fan-shaped parts, the radius sections of the fan-shaped parts coincide with the side edges of the adjacent triangular parts, and the four fan-shaped parts are each provided with an arc-shaped surface. According to the lofting method for the joint of the square-to-round trunk, the joint structure can be accurately designed and machined by using the same steel plate material, the matching precision of the joint of the square-to-round trunk and two ventilation trunks is high, and the uniformity of the material and the appearance is high.

    本发明提供了一种方转圆围井接头及其放样方法,涉及接头放样领域。方转圆围井接头包括交替设置的四个三角形部分和四个扇形部分,四个三角形部分的底边依次连接围成接头方形口,接头方形口用于与方形通风围井匹配连接;四个扇形部分的圆弧段依次连接围成接头圆形口,接头圆形口用于与圆形通风围井匹配连接;扇形部分的顶点与相邻两个三角形部分的底边交点重合,三角形部分的顶点与相邻两个扇形部分的圆弧段交点重合,扇形部分的半径段与相邻三角形部分的侧边重合,且四个扇形部分均具有圆弧形表面。该方转圆围井接头的放样方法,可使用同种钢板材料准确地设计加工出接头结构,方转圆围井接头与两种通风围井的配合精度高,材料和外观的统一性高。
