Fireproof wrapping method for fabricated steel structure beam
The invention provides a fabricated steel structure beam. The fabricated steel structure beam comprises a steel beam, a keel frame is welded to the outer surface of the lower end of the steel beam, and fireproof rock wool is arranged on the keel frame; a fiber reinforced calcium silicate board is arranged on one side, far away from the steel beam, of the outer surface of the keel frame, and the fiber reinforced calcium silicate board is arranged on the outer surface of the keel frame in a double-layer stacking mode; self-tapping screws penetrate through the outer surface of the fiber reinforced calcium silicate board, the fiber reinforced calcium silicate board is fixedly connected with the keel frame through the self-tapping screws, and fireproof cement is arranged at the joints of the self-tapping screws, the fiber reinforced calcium silicate board and a keel; and the width of the keel frame is the same as that of the bottom of the steel beam. According to the fabricated steel structure beam, a rapid and simple fireproof process is provided for the steel structure fabricated building steel beam, so that the construction period is greatly shortened, the operation difficulty of site construction and the waiting time in the construction process are reduced, and meanwhile, the fireproof performance of the steel beam is improved.
本发明提供了一种装配式钢结构梁，包括钢梁，所述钢梁的下端外表面焊接有龙骨架，且龙骨架设置有防火岩棉，所述龙骨架外表面远离钢梁的一侧设置有纤维增强硅酸钙板，所述纤维增强硅酸钙板呈双层叠加方式设置在龙骨架外表面，所述纤维增强硅酸钙板的外表面贯穿有自攻螺钉，所述纤维增强硅酸钙板与龙骨架通过自攻螺钉固定连接，所述自攻螺钉与纤维增强硅酸钙板以及龙骨的连接处设置有防火水泥，所述且龙骨架的宽度与钢梁底部的宽度相同。本发明，为一种钢结构装配式建筑钢梁提供了一种快速并且简单的防火工艺，从而大大缩短了施工工期，并且减少了现场施工的作业难度与施工工序中的等待时间，同时提高了钢梁的防火性。
