Gradient concrete protection structure with multi-cavity corrugated steel plate grating constraint function
A multi-cavity corrugated steel plate grating constrained functional gradient concrete protection structure comprises a multi-cavity corrugated steel plate grating and functional gradient concrete. The multi-cavity corrugated steel plate grating is formed by orthogonally welding a plurality of corrugated steel plates and connecting section steel according to a set arrangement mode, and the section of each small cavity in the multi-cavity corrugated steel plate grating is polygonal. The functional gradient concrete is composed of anti-crack layer concrete, anti-drilling layer concrete and anti-stripping layer concrete; the anti-stripping layer concrete, the anti-drilling layer concrete and the anti-cracking layer concrete are sequentially poured into the multi-cavity corrugated steel plate grating in a layered mode according to the set thickness proportion. By utilizing the advantages that the out-of-plane rigidity of the corrugated steel plates is large and the interface occlusal force of the corrugated steel plates and concrete is large, dislocation and slippage of the concrete and the steel plate grating in the penetration process are effectively prevented, so that the overall structure is better and synergistically stressed, and based on the characteristic that the kinetic energy of the warhead is rapidly reduced through the functional gradient concrete, the construction efficiency is improved. And the anti-penetration capability of a traditional honeycomb grid concrete protection structure is improved.
一种多腔波纹钢板格栅约束功能梯度混凝土防护结构，包括多腔波纹钢板格栅与功能梯度混凝土；多腔波纹钢板格栅由多个波纹钢板与连接型钢按照设定排列方式正交焊接而成，多腔波纹钢板格栅中各个小腔体截面形式为多边形。功能梯度混凝土由抗裂层混凝土、抗钻层混凝土与抗剥落层混凝土构成；抗剥落层混凝土、抗钻层混凝土和抗裂层混凝土按照设定厚度比例依次分层浇筑在所述多腔波纹钢板格栅中。本发明利用波纹钢板平面外刚度大、波纹钢板与混凝土的界面咬合力大的优势，有效防止了侵彻过程中混凝土与钢板格栅的错动滑移，使得整体结构更好的协同受力，并基于功能梯度混凝土快速降低战斗部动能的特性，提高传统蜂窝格栅混凝土防护结构的抗侵彻能力。
