The invention provides an improved keel with semicircular fixed joints. The improved keel comprises a U-shaped body, a plurality of semicircular holes are formed in vertical plates on two sides of theU-shaped body along the length direction of the U-shaped body, the diameter edge of each semicircular hole is connected with a horizontally outward extending mounting plate with a semicircular crosssection, the diameter edge of each mounting plate is connected with the corresponding vertical plate, one end, far away from the vertical plates, of each mounting plate is bent towards one side, closeto the corresponding semicircular hole, of an arc edge to form a first folded plate, and a fixing groove is formed between each first folded plate and the corresponding vertical plate. The keel is simple in structure, ingenious in design, of an integrally formed structure and low in production cost. During mounting, after the keel is fixed, decoration panels or ceramic tiles are directly clampedin the fixing grooves among
