Fireproof structure of steel column in severe cold area
The invention relates to a severe cold area steel column fireproof structure which comprises an interface layer attached to the surface of a steel column, a fireproof layer attached to the surface of the interface layer, a leveling layer attached to the surface of the fireproof layer, a sealing layer attached to the surface of the leveling layer and a surface layer attached to the surface of the sealing layer. The inner layer is made of a non-intumescent fire retardant coating, the outer layer is made of an intumescent fire retardant coating, and the non-intumescent fire retardant coating is mixed with fire-resistant glue. Through the structural arrangement of multiple layers of fireproof coatings, the technical problems that in the prior art, a fireproof coating on the surface of a construction steel column in a severe cold area is coarse, cracked and uneven are solved. The fireproof effect can be guaranteed, the conditions of roughness, cracking and unevenness can be avoided, the mirror surface appearance requirement for smooth surface is met, and the overall attractiveness and the building effect are met.
本发明涉及一种严寒地区钢柱防火结构，包括用于附着在钢柱表面的界面层、附着在该界面层表面的防火层、附着在该防火层表面的找平层、附着在该找平层表面的封闭层以及附着在该封闭层表面的面层，该防火层包括内层和外层，该内层的材料为非膨胀型防火涂料，该外层的材料为膨胀型防火涂料，该非膨胀型防火涂料中混合有耐火胶。本发明通过多层的防火涂料的结构设置，解决了现有技术中在严寒地区施工钢柱表面的防火涂层存在毛糙、开裂及凹凸不平的技术问题。本发明既能保证防火效果，也能避免出现现出毛糙、开裂及凹凸不平的情况，达到表面光滑的镜面外观要求，满足整体美观度及建筑效果。
