本文通过对不同复合板在弯曲及拉伸条件下的应变、挠度及声发射测试,指出在钢丝网水泥结构表面包覆玻璃钢后,大大地推迟了砂浆开裂和钢丝断裂的进程,从而大幅度地提高了原结构的强度,刚度也有所提高。机理分析还表明,再复合后的各相材料能够形成新的统一体协同工作,既可充分利用玻璃钢强度高的特点,又可充分利用原结构的刚度。表面包覆玻璃钢是对钢丝网水泥结构强化的有效途径。
In this paper, we test the strain, deflection and acoustic emission of different composite plates under bending and stretching conditions, and point out that after the coating of FRP on the surface of the steel mesh cement structure, the process of cracking and breaking of mortar is delayed greatly, Improve the strength of the original structure, stiffness has also been increased. The mechanism analysis also shows that the materials of the recombined phases can form a new unified body to work together, which can not only make full use of the high strength of FRP but also make full use of the rigidity of the original structure. Surface coating FRP is an effective way to strengthen the structure of steel mesh cement.
