(57) The purpose of the present invention is to disclose a semi-fabricated composite shielding shell with ultra-high performance concrete (UHPC), comprising an UHPC layer, a RC layer, and a back anti-crack panel. The RC layer is arranged between the UHPC layer and the back anti-crack panel, and the RC layer and the UHPC layer are connected to each other by means of connectors. Compared with the prior art, the semi-fabricated composite shielding shell has the advantages that: the UHPC layer, instead of a steel plate, is used on the side of a building having a protection requirement, damage is generally limited to the UHPC layer, and main stress reinforcements of the RC layer cannot be affected; the sizes and contours of respective components (the UHPC layer, the RC layer, and the back anti-crack panel) of the shielding shell can be flexibly adjusted according to the shape and protection requirement of the building; the rigidity-density ratio can be flexibly adjusted; the thickness of the shielding shell is greatly reduced; and the space size of the building is reduced, and construction costs are reduced. The shielding shell is suitable for the protection requirement of the building against a projectile, thus the purpose of the present invention is achieved.
