War Department On South Building Of The Qing Dynasty Construction Practice Research

This article selects in the Beijing area of modern architecture,with the War Department south building as the research object,on the basis of field investigation and related historical materials,the construction background,basic characteristics,the space form,the structure form,such as the material,practices,and build skills for carding and research,focusing on the War Department verandah parts of the south building for the construction of the computer model,analysis of reducing its adornment detail,building design method for the classification,and probes into the War Department south building repair and protection.This paper is divided into five parts.The first chapter is the introduction,on the background of the thesis,building location and historical situation are introduced,with the War Department south building related technologies of modern construction,the paper research content and the method of paper expounds the basic.The second chapter presents the basic features of the War Department south building and space construction.Analyzed from the perspective of the whole department of provincial construction overall layout,south tower of the symmetric planar space characteristics and symmetrical facade,and the profile of space form,the relationship between indoor and outdoor space,local Angle of 45 degrees symmetry and flexible adjustment is analyzed,and the brick structure of the south tower adopts types and characteristics,the use of advanced materials,brick structure with rich decoration integration system a brief overview and instructions.The third chapter mainly from the war department yamen south building brick wall,roof and floor of three basic study on segmental construction elements.In south building brick wall study,mainly analyzes the brick built material type,specification and laying mode of operation,and investigate the exterior and interior walls,both in the linear,concave,convex Angle in each layer of the building arrangement,at the same time verandah brick part of the voucher form type and manner of masonry are analyzed,the basic structure decoration integration of the facade of the brick,cornice mouldings way of set of build by laying bricks or stones are analyzed;In south tower roof study,this paper analyzes the typical triangle glyph of wooden frame components and overlapping each other way and nodes,analyzed the external Angle of convex and concave Angle within the main ShanJia and time(small)set up between roof truss,as well as the way of roofing detail structure,and analyses the two construction forms and main wall one parapet;Also for different location wood floor system,doors and Windows construction of the ceiling and handrail is studied.And demonstrated the whole construction process.The fourth chapter analyzes the verandah in close to reproduce parts of nine kinds of brick structure,the basic facade wall line,verandah part and the outer convex Angle of elevation in brick and overlapping relationship were studied.The fifth chapter probes into the War Department south building repair and protection.
