Semi-fabricated ultra-high performance concrete (UHPC) combined shielding shell
The invention aims to disclose a semi-fabricated ultra-high performance concrete (UHPC) combined shielding shell. The semi-fabricated ultra-high performance concrete (UHPC) combined shielding shell comprises a UHPC layer, an RC layer and a back anti-cracking panel; the RC layer is arranged between the UHPC layer and the back anti-cracking panel; and the RC layer and the UHPC layer are connected with each other through a connecting piece. Compared with the prior art, the semi-fabricated ultra-high performance concrete (UHPC) combined shielding shell has the advantages that the UHPC layer replaces a steel plate on the side with the protection requirement, damage is usually limited to the UHPC layer, and main stress steel bars of the RC layer cannot be affected; the size and external cooperation of all components (the UHPC layer, the RC layer and the back anti-cracking panel) of the shielding shell can be flexibly adjusted according to the shape and protection requirement of a building, the rigidity-density ratio can be flexibly adjusted, the thickness of the shielding shell is greatly reduced, the space size of the building is saved, and the engineering cost is reduced; and the shielding shell is suitable for the protection requirement of a flying object of the building, and the purpose of the shielding shell is achieved.
本发明的目的在于公开一种半装配式超高性能混凝土(UHPC)组合屏蔽壳，它包括UHPC层、RC层和背部防裂面板；所述RC层设置于所述UHPC层与所述背部防裂面板之间，所述RC层与所述UHPC层之间通过连接件互相连接；与现有技术相比，在有防护需求一侧以UHPC层替代钢板，破坏通常局限于UHPC层，不会影响RC层主受力钢筋，可根据建筑物形状和防护需求，灵活调整屏蔽壳各组成部分(UHPC、RC和背部防裂面板)的尺寸和外协，可灵活地调整刚度‑密度比，大幅度减小屏蔽壳的厚度，节省建筑物空间尺寸，降低工程造价，适用于建筑物的飞射物防护需求，实现本发明的目的。
