摘 要
掛籃作為懸臂灌筑施工的主要設(shè)備已有許多類型，有些國家如日本、法國等已有定型的系列化產(chǎn)品。我國從上世紀(jì)80年代開始使用這種技術(shù)以來，也已取得了巨大的成就。隨著我國現(xiàn)代化進(jìn)程的加快，基礎(chǔ)設(shè)施的建設(shè)飛速發(fā)展。高速公路、橋梁、隧道等基礎(chǔ)設(shè)施規(guī)模在不斷向大型化、大跨度方向發(fā)展。目前大型、大跨度橋梁的施工廣泛采用環(huán)境適應(yīng)性強(qiáng)的懸臂澆筑法。掛籃設(shè)備是進(jìn)行懸臂澆筑施工時必不可少的施工機(jī)具，其中菱形掛籃設(shè)備在大型橋梁施工中得到廣泛應(yīng)用。我國的掛籃設(shè)計制作已全部適應(yīng)懸臂施工的高強(qiáng)、輕型、大跨發(fā)展的需要，從PC連續(xù)梁或鋼構(gòu)的懸臂施工掛籃最初是平行桁架式，后來逐漸發(fā)展為多樣化，結(jié)構(gòu)越來越輕型，受力越來越合理，施工越來越方便，應(yīng)用也越來越廣泛。
本設(shè)計采用菱形掛籃，重點了解掛籃的構(gòu)造、設(shè)計方法及主要的分析計算步驟。其次，本設(shè)計主要是應(yīng)用MIDAS/Civil及OutCAD對掛籃進(jìn)行設(shè)計，需學(xué)習(xí)掌握MIDAS/Civil及OutCAD。
掛籃是懸臂施工的關(guān)鍵設(shè)備，掛籃的主要功能是支撐模板，承受新澆混凝土重量。掛籃通常都由以下幾個部分組成：承重系統(tǒng)、懸吊系統(tǒng)、模板系統(tǒng)、錨固裝置、走行系統(tǒng)和工作平臺。
掛籃的內(nèi)模、外模、底模及主桁架計算是掛籃設(shè)計的主要組成部分，本文進(jìn)行講解。從掛籃的受力計算開始分析，通過強(qiáng)度驗算、撓度檢算設(shè)計出最合適的掛籃截面尺寸，來滿足掛籃設(shè)計所要達(dá)到的要求。本設(shè)計中還有很多不足之處，望能提出寶貴意見，特此感謝。

Abstract
Basket as cantilever construction of major equipment, there are many types, some countries such as Japan and France have finalized a series of products. 80 years from the last century, China began using this technique has also made great achievements. Highways, bridges, tunnels and other infrastructure continue to scale in large, long-span direction. At present large-scale, long-span bridge construction widely used in environmental adaptability of the cantilever casting method. Hanging Cantilever construction equipment is carried out when necessary construction machinery, including a large diamond-shaped hanging basket device widely used in bridge construction. Hanging Basket Design China have all been adapted cantilever construction of high-strength, lightweight, long-span development, from a PC or a steel cantilever beam was initially parallel to the truss construction Hanging type, then gradually developed into a diversified structure increasingly The more light, more and more reasonable force, the construction more convenient, more and more widely applied.
This design uses Lozenge hanging basket, introduced the triangular cradle design principles, triangular cradle design, construction methods and the main calculation steps, described cantilever construction technique. The process of mapping and calculating the main use of MIDAS / Civil and OutCAD engineering software
Hanging is the cantilever construction of key equipment, Cradle main function is to support the template, to bear the weight of fresh concrete. Hanging usually by the following components: load-bearing system, suspension system, template system, anchoring devices, running the system and working platform
Hangs basket's cast, the outline templet, the bottom die and the principal truss computation is hangs the basket design the key component, this article carries on the explanation. From hangs basket's stress computation to start to analyze, through the intensity checking calculation, the amount of deflection examines calculated that designs appropriately hangs the basket section size, hangs the request which satisfiedly the basket design must achieve. In this design also has many deficiencies, looks can propose the valued suggestion, thanks specially.
