The complexity of long-span steel structure and the diversity of construction methods are the problems that must be considered in the design. This is an aspect that is often ignored or poorly considered in the design process. The construction mainly includes the following installation technologies. During the construction, the following problems should be paid attention to: the installation of complex space steel structure should be measured and controlled. As measurement and control is a part of steel structure construction technology, its construction scheme is reasonable and advanced. Through a large number of measurement and control data, the results are analyzed and verified. For long-span steel structure, due to the large difference of deformation and stress state in the construction process and after forming, it is necessary to use a variety of supporting tires to ensure the accuracy of the structure.

　　1.即拆卸控制

　　1. Disassembly control

　　由于大跨度鋼結構總卸貨噸位大、分布廣泛的卸貨點,單點卸載壓力,卸貨工作負載的計算和分析,如大,如果不合理的支持力量的釋放,將會破壞結構或使腳手架逐漸穩定。因此,卸貨的鋼結構必須進行嚴格按照兩個卸載方法的要求,等于比率法和等距離法,基于結構的計算和分析,針對結構的,以變形協調為核心,實時監控保證。

　　Due to the large tonnage and wide distribution of unloading points, single point unloading pressure and calculation and analysis of unloading working load of large-span steel structure, if the unreasonable support force is released, the structure will be damaged or the scaffold will be gradually stable. Therefore, the unloading steel structure must be strictly in accordance with the requirements of the two unloading methods, equal to the ratio method and the equal distance method. Based on the calculation and analysis of the structure, aiming at the safety of the structure, the deformation coordination is the core and real-time monitoring is guaranteed.

　　大跨度鋼梁吊裝,如果沒有合理的吊點計算,仍然選擇傳統的兩段,由于鋼結構較長,吊點間距較大,重量和可變負荷等因素,鋼梁和鋼絲繩的軸向力很大,容易梁橫向彎曲,甚更嚴重的變形。

　　For the hoisting of long-span steel beams, if there is no reasonable calculation of lifting points, the traditional two sections are still selected. Due to the long steel structure, large distance between lifting points, weight and variable load and other factors, the axial force of steel beams and steel wire ropes is very large, which makes it easy for the beams to bend laterally or even to deform more seriously.

　　加強大跨度鋼結構施工現場，增加對施工人員的知識培訓，使其對鋼構件的力學特性和吊裝知識有更具體的了解。同時加強施工組織設計對吊裝方案進行合理論證，以選擇更合理的吊裝方案。

　　Strengthen the construction site of large-span steel structure, increase the professional knowledge training of construction personnel, so that they have a more specific understanding of the mechanical characteristics of steel members and lifting knowledge. At the same time, strengthen the construction organization design to carry on the reasonable demonstration to the hoisting scheme, in order to choose the more reasonable hoisting scheme.

　　3安裝順序

　　3 installation sequence

　　由于大跨度鋼結構對安裝順序的要求較高，如果安裝順序考慮不當，鋼構件不滿足吊裝的需要，可能會影響結構的。在施工組織設計中，合理安排安裝順序，統一協調工廠加工、構件運輸和現場安裝。在施工過程中，要嚴格執行。除了認真制定適合本工程的安裝順序外，還應選擇有經驗的施工隊伍進行安裝，避免潛在的質量隱患。

　　Due to the high requirements of large-span steel structure on the installation sequence, if the installation sequence is not considered properly, the steel members do not meet the needs of hoisting, which may affect the safety of the structure. In the construction organization design, reasonably arrange the installation sequence, and coordinate the factory processing, component transportation and site installation. In the process of construction, it shall be strictly implemented. In addition to carefully formulating the installation sequence suitable for the project, experienced construction team shall be selected for installation to avoid potential quality hazards.

　　大跨度鋼結構廣泛應用于具體工程項目中。針對施工過程中出現的各種問題，加強施工組織和設計的優化，強化質量紅線，不斷提高施工工藝。

　　Large span steel structure is widely used in specific projects. In view of various problems in the construction process, strengthen the optimization of construction organization and design, strengthen the red line of safety and quality, and constantly improve the construction technology.
