Construction method of basement stair firewall
The invention discloses a construction method of a basement stair firewall. The construction method comprises the following steps that 1, field measurement is conducted; 2, construction preparation isconducted; 3, a firewall is built, specifically, a, a steel structure formwork is erected; b, a firewall foundation is poured; c, a firewall is built; d, quality inspection of the firewall is conducted; e, a firewall surface is constructed; f, wall painting is conducted; and g, firewall acceptance is conducted; 4, firewall maintenance is conducted, specifically, professionals are selected to conduct daily protection on the firewall and a firewall constructional column; and 5, construction is finished. The construction method is reasonable in structure, when the basement stair firewall is constructed, the perpendicularity and flatness of the firewall surface are controlled, the thicknesses of plaster layers on the two sides are controlled to be 25 mm, plaster on each side is controlled tobe 12.5 mm, the problem that the plaster layers occupy the clearance of a stair flight is effectively solved, meanwhile, the center line of a handrail is flush with the outer edge of the firewall, andthe net width of a stair is prevented from being occupied.
本发明公开了一种地下室楼梯防火墙的施工方法，施工方法包括以下步骤：步骤一、现场测量；步骤二、施工准备；步骤三、防火墙砌筑：a、钢结构模板支设；b、防火墙基础浇筑；c、防火墙砌筑；d、防火墙质检；e、防火墙面构筑；f、墙面粉刷；g、防火墙验收；步骤四、防火墙养护：选派专业人士对防火墙和防火墙构造柱进行日常防护；步骤五、施工结束，本发明结构合理，在地下室楼梯防火墙构筑时，把控防火墙面的垂直度和平整度，将两侧抹灰层厚度控制在25mm，每侧抹灰12.5mm，有效解决抹灰层占据梯段净空问题，同时扶手的中心线与防火墙外边相平齐，避免占用楼梯净宽。
