【摘要】： 網(wǎng)架結(jié)構(gòu)憑借自身受力簡單、剛度大、自重輕、節(jié)約鋼材及整體穩(wěn)定性好等優(yōu)點(diǎn),已被越來越被廣泛地運(yùn)用于各類工業(yè)、民用建筑中,特別是各類體育場、會(huì)展大廳、飛機(jī)維修庫等大跨度結(jié)構(gòu)。 目前,大型空間網(wǎng)架結(jié)構(gòu)的施工方法多種多樣,其多樣化及復(fù)雜化造成了施工階段結(jié)構(gòu)內(nèi)力分布的復(fù)雜性和最終成型結(jié)構(gòu)受力的可變性,大跨空間網(wǎng)架結(jié)構(gòu)施工過程的安全性與成形狀態(tài)是否能滿足設(shè)計(jì)要求是工程界必須解決的問題。同時(shí),施工方案的的選擇還涉及到施工難易程度、工期及成本等一系列問題。因此,對(duì)網(wǎng)架結(jié)構(gòu),一個(gè)好的安裝方法至關(guān)重要。 本文闡述了網(wǎng)架的形式分類及各類網(wǎng)架的特點(diǎn),論述了網(wǎng)架結(jié)構(gòu)的一般施工方法,包括高空散裝法、分條(塊)安裝法、高空滑移法、整體吊裝法、整體提升法以及整體頂升法,比較了這些施工方法各自的優(yōu)缺點(diǎn)及適合的使用范圍. 本文重點(diǎn)論述了大跨度網(wǎng)架的整體提升方法。從構(gòu)件的制作、網(wǎng)架的地面拼裝到液壓技術(shù)原理和同步計(jì)算機(jī)控制技術(shù),以上海浦東機(jī)場波音機(jī)庫屋蓋結(jié)構(gòu)工程建設(shè)為研究背景,在原有的整體提升的技術(shù)基礎(chǔ)上,提出了網(wǎng)架兩次或多次整體提升時(shí)若干難題的解決方案。同時(shí)結(jié)合空間大跨度鋼結(jié)構(gòu)施工階段力學(xué)分析方法,應(yīng)用MIDAS/GEN軟件,對(duì)該工程中的提升過程作了模擬分析,其分析結(jié)果與實(shí)測數(shù)據(jù)具有較好的一致性,表明該分析方法可為類似工程提供參考。
[Abstract]:With the advantages of simple force, large stiffness, light weight, saving steel and good overall stability, the grid structure has been more and more widely used in all kinds of industrial and civil buildings, especially in all kinds of stadiums, exhibition halls, etc. Large-span structures such as aircraft maintenance depots. At present, there are a variety of construction methods for large space truss structures, which make the complexity of the distribution of internal forces in the construction stage and the variability of the ultimate formed structure force. Whether the safety and forming state of long-span space truss structure can meet the design requirements is a problem that must be solved in the engineering field. At the same time, the selection of construction scheme involves a series of problems, such as construction difficulty, time limit and cost. Therefore, to the grid structure, a good installation method is very important. In this paper, the form classification of grid structure and the characteristics of all kinds of space truss are expounded, and the general construction methods of grid structure are discussed, including high altitude bulk method, partition (block) installation method, high altitude slip method, integral hoisting method, etc. The advantages and disadvantages of the whole lifting method and the whole lifting method are compared. This paper focuses on the whole lifting method of long-span space frame. From the production of components, the ground assembly of the grid to the hydraulic technology principle and synchronous computer control technology, taking the construction of Boeing hangar roof structure of Shanghai Pudong Airport as the research background, on the basis of the original integral lifting technology, In this paper, the solutions of some difficult problems in two or more integral lifting of the grid are proposed. At the same time, combined with the method of mechanical analysis in the construction stage of spatial large-span steel structure, the lifting process of the project is simulated and analyzed by using MIDAS/GEN software. The results of the analysis are in good agreement with the measured data. It is shown that the analytical method can be used as a reference for similar projects.
