Zusammenfassung:	Provided is a radius-adjustable arc truss-type enclosing purlin. The radius-adjustable arc truss-type enclosing purlin comprises arc rods, transverse rods and sleeve connection rods. The two transverse rods, the multiple arc rods of same lengths and the multiple groups of sleeve connection rods with different lengths are combined via connection bolts to be an arc truss-type member. The transverse rods are connected with an adjuster via an adjusting screw rod. The chord length of the arc truss-type member can be adjusted. The sleeve connection rod is in the form of sleeve-connected connection capable of adjusting the height of the arc truss-type member.The radius-adjustable arc truss-type enclosing purlin has following beneficial effects: through the adjusting screw rod arranged on the transverse rod, the adjuster and the sleeve connection rod, the chord length and the height of the arc truss-type member can be adjusted so that the arc radius of the arc truss-type enclosing purlin is changed; and the radius-ad
