雙機(jī)位機(jī)庫(kù)超大型網(wǎng)架整體提升技術(shù)

中國(guó)東方航空公司雙機(jī)位機(jī)庫(kù)位于上海虹橋國(guó)際機(jī)場(chǎng)東北側(cè),其橫向跨度l50m,縱向深度90m,面積14728m2,相當(dāng)于兩個(gè)標(biāo)準(zhǔn)足球場(chǎng),可同時(shí)進(jìn)行2架大型客機(jī)的維修、保養(yǎng)。
機(jī)庫(kù)共設(shè)32根鋼筋混凝土立柱,呈凹字形分布。
A軸處立柱為截面4m×2m、壁厚0.4m、高22.5m的矩形柱,其它為高25.9m的四肢組合柱。
兩種組合柱的四肢間由高70cm、寬25cm的混凝土梁連接,連梁間中心距一般為3m。
由于大門處150m的跨度間不設(shè)柱子,因而A、B軸處4根柱子承受的荷載達(dá)網(wǎng)架總重量的三分之二。

該機(jī)庫(kù)屋蓋鋼結(jié)構(gòu)網(wǎng)架由21萬(wàn)套M22、M24扭剪型和M30大六角頭的高強(qiáng)度螺栓將1000多種型號(hào)的桿件連接而成。
提升網(wǎng)架重量3200t

China Eastern Airlines hangar pairs located in Shanghai Hongqiao International Airport, northeast, its horizontal span l50m, vertical depth of 90m, an area of 14728m2, the equivalent of two standard pitches, which can carry out two major aircraft repair and maintenance. Hangar A total of 32 reinforced concrete columns, concave-shaped distribution. A column axis for the cross-section 4m × 2m, thickness 0.4m, high-22.5m rectangular columns, the other limb combination of high-25.9m column. Combination of columns between the two limbs by high-70cm, width 25cm of concrete beam connections, and even away from the beam center is generally 3m. As the gate between the span of 150m with no columns, and thus A, B-axis at four columns to withstand loads up to two-thirds of the total weight of truss.
Hangar roof steel truss from 21 million sets of M22, M24 and M30 torsional shear type high strength bolts with large hexagon head will be more than 1000 kinds of models of bars connection made. Enhance the grid weight of 3200t
