【摘要】：建筑能耗在社會總能耗中占據(jù)了很大的比例，伴隨著我國經濟的飛速發(fā)展，人們對建筑領域的節(jié)能降耗提出了更高的要求。建筑外保溫技術作為一種重要的保溫節(jié)能手段被廣泛使用。以干掛石材幕墻為代表的外保溫層中通常存在的鋼連接件作為一種貫通式的熱橋，是熱量大量散失的通道，因此對此種建筑熱橋傳熱的研究十分重要。 我國目前設計普遍采用二維CAD技術作為輔助手段對熱橋傳熱進行計算和保溫補償設計，設計中建筑的平面和立面以及詳圖都是分開的，很難對具體的耗能部位及耗能狀況進行量化分析。而以三維建筑信息模型為中心的BIM技術利用三維繪圖工具，能夠對建筑設計的各個方面、各種部位進行詳細的描述，在準確描述節(jié)點構造的基礎上，提供不同形式的接口與各種分析軟件協(xié)同對接，，可進行建筑能耗模擬，實現(xiàn)建筑能耗的定量化分析�；谏鲜鰞�(yōu)點，BIM技術將是未來建筑設計與能耗模擬的一個重要途徑。 本文首先針對石材幕墻外保溫體系存在的貫通式熱橋，采用多回路熱橋傳熱測試儀，在現(xiàn)場進行冬季工況實測分析，獲得實際案例的溫度分布及傳熱實際數(shù)據(jù)作為下一步模擬的依據(jù)；并且，采用建筑能耗模擬技術的研究方法，以實際工程中采用的干掛石材幕墻金屬連接件和預埋件為原型，通過對建筑的精確建模，正確賦予建筑物模型材質以及環(huán)境參數(shù)，得到與實際建筑一致的建筑模型，依據(jù)IFC標準將模型導入模擬分析軟件進行傳熱模擬分析。通過實測和模擬，探索整套的BIM思維方式下的熱橋模擬方法。 本文的研究成果是使用BIM技術建立熱橋的傳熱模擬分析提供了一定的理論指導。通過深入研究建筑外圍護結構熱橋的傳熱過程，精確模擬石材幕墻熱橋傳熱為建筑節(jié)能提供一種新的研究方法。本文的工作將為落實環(huán)保低碳的設計理念，促進建筑節(jié)能設計具有一定的理論和實踐的指導意義。
[Abstract]:Building energy consumption occupies a large proportion in the total social energy consumption, along with the rapid development of our economy. People have put forward higher requirements for energy saving and consumption reduction in the field of building. As an important means of heat preservation and energy saving, the external insulation technology is widely used. The steel connection usually exists in the outer insulation layer represented by the dry hanging stone curtain wall. The connectors are used as a through type of hot bridge. It is important to study the heat transfer of this kind of thermal bridge because it is a channel with a large amount of heat loss. At present, two-dimensional CAD technology is widely used in the design of thermal bridge heat transfer calculation and thermal insulation compensation design, the design of the building's plane, facade and detail drawings are separated. It is difficult to analyze the specific energy consumption parts and energy dissipation status quantitatively, but the BIM technology, which takes the three-dimensional building information model as the center, can make use of the three-dimensional drawing tool to make use of the various aspects of the architectural design. On the basis of accurate description of node structure, various parts are described in detail, and different forms of interface are provided to coordinate with various analysis software, which can be used to simulate building energy consumption. Based on the above advantages, BIM technology will be an important way of building design and energy consumption simulation in the future. In this paper, first of all, in view of the existence of the stone curtain wall heat preservation system through the heat bridge, using multi-loop heat bridge heat transfer tester, on the spot to carry out the field analysis of the winter conditions. The actual data of temperature distribution and heat transfer are obtained as the basis of the next simulation. In addition, using the research method of building energy consumption simulation technology, taking the dry-hanging stone curtain wall metal connection and embedded parts as the prototype, through the accurate modeling of the building. According to the IFC standard, the model is imported into the simulation analysis software for heat transfer simulation analysis. To explore the whole BIM thinking mode of thermal bridge simulation method. The research result of this paper is that the heat transfer simulation analysis of the thermal bridge with BIM technology provides a certain theoretical guidance. Through in-depth study of the heat transfer process of the thermal bridge outside the building envelope structure. Accurate simulation of heat transfer of stone curtain wall provides a new research method for building energy saving. The work of this paper will be for the implementation of the design concept of environmental protection and low carbon. To promote the building energy-saving design has a certain theoretical and practical significance.
