    • A blast-resistant barrier comprising a plurality of units each including a panel having a thickness of greater than 20 to less than 40 millimeter is disclosed. The panel is in the form of a monolithic polycarbonate sheet or laminate that is positioned vertically between the source of a blast and the blast target, the laminate including at least two polycarbonate sheets and an optional image layer interposed therebetween. The panel is fixedly attached to a frame which is firmly embedded in concrete in a manner calculated to provide stiffness sufficient to absorb and withstand external forces resulting from said blast. In a preferred embodiment the panel includes at least two polycarbonate sheets laminated one to the other, optionally including an image layer interposed therebetween. In an additional embodiment, the frame is anchored securely to the target enabling dissipation of the blast force through the target's structure. The height of the blast-resistant barrier is preferably proportional to the height of the target.
    • 公开了包括多个单元的防爆屏障,每个单元包括厚度大于20毫米至小于40毫米的面板。 面板是整体聚碳酸酯片材或层压材料的形式,其垂直放置在鼓风源和鼓风靶材之间,所述层压材料包括至少两个聚碳酸酯片材和插入其间的可选图像层。 面板固定连接到框架上,该框架被牢固地嵌入混凝土中,其计算方式是提供足够的硬度来吸收和承受由所述爆炸产生的外力。 在一个优选实施例中,面板包括至少两个彼此层压的聚碳酸酯片材,可选地包括置于其间的图像层。 在另外的实施例中,框架被牢固地锚定到目标,从而能够通过目标结构消除爆炸力。 防爆屏障的高度优选与目标的高度成比例。
