Fiberboard reinforced polyurethane high-damping shock insulation support
The invention relates to the technical field of civil engineering, in particular to a fiberboard stiffening polyurethane high-damping shock insulation support which comprises a fiberboard stiffening layer, a polyurethane elastic layer and a polyurethane protective layer. The fiberboard stiffening layer and the polyurethane elastic layer are overlapped up and down to form an internal structure of the support; the polyurethane protection layer covers the top, the bottom and the periphery of the internal structure; the polyurethane elastic layer and the polyurethane protective layer are both made of chopped fiber modified polyurethane materials. According to the fiberboard stiffening polyurethane high-damping shock insulation support, the chopped fibers are added into the polyurethane material, the tensile strength, the tearing strength and the damping performance of the polyurethane elastic layer are improved, and then the vertical bearing capacity and the energy dissipation capacity of the support are improved.
本发明涉及土木工程技术领域，尤其是涉及一种纤维板加劲聚氨酯高阻尼隔震支座，包括纤维板加劲层、聚氨酯弹性层和聚氨酯保护层；所述纤维板加劲层和聚氨酯弹性层上下交叠设置形成支座的内部结构；所述聚氨酯保护层包覆于内部结构的顶部、底部以及四周；所述聚氨酯弹性层和聚氨酯保护层均为短切纤维改性的聚氨酯材料。本发明的纤维板加劲聚氨酯高阻尼隔震支座通过在聚氨酯材料中加入短切纤维，提高了聚氨酯弹性层的拉伸强度、撕裂强度和阻尼性能，进而提高了支座竖向承载力和耗能能力。
