Gymnasium roof steel structure mounting method
The invention provides a gymnasium roof steel structure installation method. The gymnasium roof steel structure installation method comprises the steps that S1, a steel structure is transported to a site; s2, steel column installation is conducted, and secondary grouting is conducted on steel column bottom feet; s3, pre-deformation values are reserved during machining and lofting of all splicing units of the truss, and trial hoisting is carried out after splicing is completed; s4, the main truss on one side of the opening and closing opening of the gymnasium is installed firstly, then the main truss on the other side of the opening and closing opening of the gymnasium is installed, and S5, prestressed inhaul cable construction is conducted after roof steel structure construction is completed. Steel columns used for supporting the main trusses are adjusted through nuts, secondary pouring is conducted after adjustment, so that the assembling accuracy and stability of the main trusses are guaranteed, a hoisting scheme is optimized, a gymnasium self-opening and closing opening is divided into the two sides, the main trusses on the two sides of the gymnasium opening and closing opening are sequentially installed, and therefore the stability of the main trusses in the construction process is guaranteed; and the construction safety is ensured.
本发明提供一种体育馆屋盖钢结构安装方法，包括：步骤S1，钢结构运输进场；步骤S2，进行钢柱安装，并对钢柱底脚进行二次灌浆；步骤S3，桁架各拼接单元在加工放样时预留预变形值，拼装完成后进行试吊；步骤S4，首先进行体育馆开合口其中一侧的主桁架安装，然后进行体育馆开合口另一侧的主桁架安装，步骤S5，屋盖钢结构施工完成后进行预应力拉索施工。对用于支撑主桁架的钢柱通过螺帽进行调整，调整后二次灌注以此保证主桁架装配的精确性和稳定性，优化吊装方案，将体育馆自开合口分为两侧，依次进行体育馆开合口两侧的主桁架安装，从而保证施工过程中主桁架的稳定性，保证施工的安全性。
