Fireproof and antiknock multi-fortification combined shear wall
The invention discloses a fireproof and antiknock multi-fortification combined shear wall, and belongs to the technical field of shear walls. The shear wall comprises a negative Poisson's ratio layer, a high-damping mortar layer, a reinforced rubber aggregate concrete layer, a high-damping mortar layer and a UHPC steel reinforced concrete layer which are sequentially arranged from the outer side to the inner side. Compared with the prior art, the anti-explosion shear wall has the beneficial effects that explosion impact is blocked layer by layer by using a multi-fortification method, the possibility of overall collapse of the wall body after the wall body is subjected to explosion impact is greatly reduced, and meanwhile, the high-damping mortar layer can also play a role in energy consumption, so that the anti-explosion performance of the shear wall is greatly improved, and the service life of the shear wall is prolonged. It is ensured that the bearing capacity can be kept due when the device is subjected to explosion impact; and finally, the fireproof coating is coated, so that the fire resistance of the shear wall is improved, and fire disasters possibly occurring after explosion can be well coped with.
本发明公开了一种防火抗爆多重设防组合剪力墙，属于剪力墙技术领域。该剪力墙包括由外侧向内侧方向依次设置的负泊松比层、高阻尼砂浆层、钢筋橡胶集料混凝土层、高阻尼砂浆层、UHPC型钢混凝土层。本发明相较于现有技术，其有益效果在于：使用多重设防的方法层层阻隔爆炸冲击，大大降低了墙体受到爆炸冲击后发生整体倒塌的可能性，同时高阻尼砂浆层也可以起到耗能作用，从而大幅提高了剪力墙的抗爆性能，确保其在受到爆炸冲击时可以保持应有的承载力；最后，涂设防火涂层提高了剪力墙的抗火性能，可以很好地应对爆炸后可能发生的火灾。
