Lamination solid-liquid two-phase solution steel plate protective armor wrapped with high-performance fiber cloth

Abstract

The invention provides a lamination solid-liquid two-phase solution steel plate protective armor wrapped with high-performance fiber cloth. The lamination solid-liquid two-phase solution steel plate protective armor wrapped with the high-performance fiber cloth comprises inner layer high-performance fiber cloth, steel plates, solid-liquid two-phase solution, engineering filler, edge-sealed plates, an adhesive agent and outer layer high-performance fiber cloth. Compared with adding the section thickness of a building main structure, the provided lamination solid-liquid two-phase solution steel plate protective armor wrapped with the high-performance fiber cloth has better missile-impact proofing and protecting effect, and excessive modification on the arrangement of the main structure is not required.

Description

technical field [0001] The invention relates to the design of a building structure protection technology with special protection requirements in the field of civil engineering, in particular to a high-performance fiber cloth-wrapped laminated solid-liquid two-phase solution steel plate protective armor. Background technique [0002] Terrorist activities are becoming more and more rampant in today's world, especially since the 9.11 incident, how to deal with terrorist organizations using commercial aircraft and other large projectiles to attack important buildings (such as nuclear power plants, commercial center buildings, etc.) Infringement has become an important and urgent subject that all countries are scrambling to study. For example, after the 9.11 incident, for the new nuclear power plants in the United States, the US Nuclear Regulatory Commission (NRC) clearly required that the design should take into account the impact of large commercial aircraft, and also conducted...

Problems solved by technology

[0004] In order to deal with the threat of large missiles, traditional methods such as increasing the cross-sectional size of the main structure are generally used in the structural design of new buildings, and the existing buildings are generally reinforced by enlarging the cross-section reinforcement method, external steel reinforcement method, and bonded steel reinforcement method. methods, these methods have certain application value in the engineering field, and because the focus of these methods is to increase the rigidity of the structure, the effect of resisting high-speed impact is not good, and there are complex construction techniques, difficult guarantee of project quality, construction and maintenance costs Insufficient high

[0005] According to the results of the novelty search conducted by the inventor, no technical solution has been proposed in the world to use external high-performance fiber cloth to wrap laminated solid-liquid two-phase solution steel plate protective armor to improve the impact resistance of important buildings
