【摘要】：建筑師與結(jié)構(gòu)工程師一直在尋求解決空間整體結(jié)構(gòu)問題的新思路，隨著現(xiàn)代世界工業(yè)化的發(fā)展，對大跨度結(jié)構(gòu)的功能要求也越來越強(qiáng)烈，基于空間網(wǎng)格的一系列優(yōu)點(diǎn)如載荷分?jǐn)�、設(shè)備安裝、堅(jiān)固性、模數(shù)單元組件、支座位置選擇有很大的自由度、規(guī)則的幾何形狀和便于安裝等。空間網(wǎng)格結(jié)構(gòu)無疑是建筑師和結(jié)構(gòu)工程師們探索開拓這些新結(jié)構(gòu)形式的有效工具。本文介紹了空間網(wǎng)格結(jié)構(gòu)最常用的結(jié)構(gòu)形式：大跨度鋼網(wǎng)架結(jié)構(gòu)。 隨著空間網(wǎng)格結(jié)構(gòu)的發(fā)展，其安裝施工工藝也逐步成為了人們重點(diǎn)研究的對象，目前，一般的施工方法包括：高空散拼法、整體提升法、整體頂升法、分段吊裝法、滑移法等。整體提升法的適用性和靈活性相比較其他施工方法其適用范圍更廣，是本文重點(diǎn)研究的施工方法。 由于大跨度鋼網(wǎng)架結(jié)構(gòu)極其復(fù)雜，涉及桿件的種類繁多，若能結(jié)合建筑信息模型BIM的應(yīng)用，能大大提高施工效率。BIM由三部分內(nèi)容組成：BIM具體表現(xiàn)為在三維模型構(gòu)件屬性中能包含尺寸、造價(jià)、時(shí)間及其他信息等；能夠利用BIM技術(shù)建立一個(gè)包含項(xiàng)目全生命周期各項(xiàng)資料的資源共享平臺，為決策、設(shè)計(jì)、施工、竣工、投產(chǎn)運(yùn)營過程中的各項(xiàng)決策提供依據(jù)；在工程項(xiàng)目運(yùn)行的不同階段，各個(gè)單位可通過BIM平臺實(shí)現(xiàn)協(xié)同作業(yè)。 本文首先介紹了整體提升原理及提升系統(tǒng)組成。其次，以廣州白云機(jī)場某維修機(jī)庫項(xiàng)目為例，，研究了大跨度鋼網(wǎng)架結(jié)構(gòu)在整體提升方案編制階段、網(wǎng)架拼裝階段、提升施工階段出現(xiàn)的影響較大的問題及解決措施，有利于以后類似項(xiàng)目參考本文，重點(diǎn)對易出現(xiàn)問題的地方進(jìn)行嚴(yán)格把握。最后，BIM作為一門新技術(shù)，已逐步開始被人們接受和認(rèn)可，必定會成為替代CAD技術(shù)，成為發(fā)展趨勢。本文利用大跨度鋼網(wǎng)架結(jié)構(gòu)項(xiàng)目及建筑信息模型BIM，研究了網(wǎng)架結(jié)構(gòu)以下方面的內(nèi)容：基于BIM的鋼網(wǎng)架結(jié)構(gòu)建模及應(yīng)用研究；基于BIM的施工技術(shù)資料集成研究；基于BIM的三維施工模擬研究；基于BIM的在各個(gè)階段的成本管理研究，為類似結(jié)構(gòu)體系應(yīng)用BIM技術(shù)提供了一定的參考依據(jù)。
[Abstract]:Architects and structural engineers have been looking for new ideas to solve the problem of integral space structures. With the development of industrialization in the modern world, the functional requirements of long-span structures are becoming more and more intense. A series of advantages based on spatial grid such as load allocation, equipment installation, firmness, module and digital unit components, support position selection have a great degree of freedom, regular geometry and easy to install and so on. Spatial grid structure is undoubtedly an effective tool for architects and structural engineers to explore and exploit these new structural forms. In this paper, the most commonly used spatial grid structure, long span steel grid structure, is introduced. With the development of space grid structure, the installation and construction technology has gradually become the focus of research. At present, the general construction methods include: high altitude dispersion spelling, integral lifting, subsection hoisting, sliding, etc. Compared with other construction methods, the applicability and flexibility of the whole lifting method is wider, which is the construction method which is studied in this paper. Because the large span steel grid structure is extremely complex and involves many kinds of members, if we can combine the application of building information model BIM, It can greatly improve the construction efficiency. BIM is composed of three parts: BIM can include dimension, cost, time and other information in the attribute of 3D model component. Can use BIM technology to set up a resource sharing platform which contains all the information in the whole life cycle of the project, which can provide the basis for the decision making, design, construction, completion and operation of the project in the different stages of the project operation. Each unit can realize cooperative operation through BIM platform. This paper first introduces the whole lifting principle and the composition of the lifting system. Secondly, taking a maintenance hangar project of Guangzhou Baiyun Airport as an example, this paper studies the problems and solutions of the large span steel grid structure in the stage of overall lifting scheme preparation, the construction stage of grid installation and the stage of hoisting construction. In the future, similar projects refer to this article, focusing on the easy problems to be strictly grasped. Finally, as a new technology, BIM has been gradually accepted and recognized by people, and will certainly become a substitute for CAD technology and become a trend of development. In this paper, the following aspects of grid structure are studied by using long span steel grid structure project and building information model BIM,: modeling and application research of steel grid structure based on BIM, construction technical data integration research based on BIM, and construction technology data integration based on BIM. The research on 3D construction simulation based on BIM and cost management in each stage based on BIM provides a certain reference for the application of BIM technology in similar structure system.
