In modern construction projects, reinforced concrete structures have been widely used, and as a special building material, steel plays an extremely important role. In 2009, the total amount of steel used for construction in China exceeded 110 million tons, which is close to half of China's steel output. It is the largest user of metallurgical industry in China, and the consumption of threaded steel accounted for about 23% of the total amount of steel. However, the standard shape of rebar used for construction is messy, and the rebar material produced by rebar factories can not be directly used in engineering. Generally, it is required to pass the process according to the requirements of construction drawings.

　　現在大部分地區修建用鋼筋長期以來依托人力來進行加工，隨著一些鋼筋加工設備的呈現，才使之變為半機械化加工方法，加工地址主要在鋼筋銷售點或施工工地現場 進行加工，由于所運用的鋼筋加工機械技能功能、自動化程度和加工能力較低，嚴峻限制修建施工現代化的進步，給施工管理帶來很大的麻煩，而且這種加工方法具 有勞動強度大，加工質量難以控制，加工功率底，材料和能源浪費高，加工本錢高，隱患多，占地大，噪音大等缺陷。

　　At present, most of the construction of steel bars have been processed by manpower for a long time. With the appearance of some steel bar processing equipment, it has become a semi-mechanized processing method. The processing address is mainly processed at the steel bar sales point or construction site. Due to the low function, automation and processing ability of the steel bar processing machinery, the construction is severely restricted. The progress of modernization has brought great trouble to construction management, and this processing method has such defects as high labor intensity, difficult to control the processing quality, low processing power, high waste of materials and energy, high processing cost, many hidden dangers of safety, large occupation of land and large noise.

　　所謂修建鋼筋商品化加工配送，就是將工程所需求的各種不同類型的鋼筋依照修建結構的實際尺度，由自動控制機械加工成型（盤條鋼筋矯直、剪切，棒材鋼筋定尺剪切，鋼筋曲折成型,鋼筋網片成型，鋼筋接頭機械銜接加工；鋼筋籠、柱等大型預制鋼筋件成型等），以實際施工時刻運往修建工地直接運用。

　　The so-called commercial processing and distribution of construction reinforcement means that the various types of reinforcement required by the project are automatically controlled by mechanical processing according to the actual scale of the construction structure (straightening and shearing of wire bars, shearing of bar bars at fixed length, bending and bending of steel bars, forming of steel mesh, mechanical jointing of steel bars, forming of large prefabricated steel bars such as steel cages and columns, etc.). It is transported to the construction site for direct use at the actual construction time.

　　混凝土結構修建工程施工主要分為三個部分：混凝土、鋼筋和模板。這三個方面的開展情況反映了修建工業化和施工技能的開展水平。開展鋼筋商品化加工配送是為了 改變修建用鋼筋加工分散落后面貌，以技能手段和方法實現化、規?；\營，進步鋼筋加工質量，為施行的施工技能提供物質基礎，必然會進步工程質 量、下降工程本錢、進步機械化施工水平，添加經濟效益和社會效益，契合社會開展的需求。

　　The construction of concrete structure is mainly divided into three parts: concrete, steel bar and formwork. The development of these three aspects reflects the development level of construction industrialization and construction skills. The purpose of developing commercial processing and distribution of reinforcing bars is to change the backward situation of reinforcing bars in construction, to realize specialized and large-scale operation with advanced technical means and methods, to improve the quality of reinforcing bars processing and to provide material basis for implementing advanced construction skills, which will inevitably improve engineering quality, reduce engineering cost, improve the level of mechanized construction, and to add economic and social benefits. Benefits are in line with the needs of the society.

　　鋼筋加工配送是基本建造開展的需求。

　　Steel bar processing and distribution is the demand of basic construction.

　　修建業開展已被列為國民經濟開展四大支柱產業之一，“十五”期間出資仍然是基礎設施建造和住宅產業。房地產業在2010年以前將持續快速增長：2008年鄉鎮房屋修建竣工面積到達48.2萬，運用鋼材 1.83萬噸；2009年鄉鎮房屋修建竣工面積到達50.13萬，運用鋼材1.9萬噸；2010年鄉鎮房屋修建竣工面積估計可達60萬平米，運用鋼材2.28萬噸。大規模的建造工程為鋼筋加工制品提供了廣闊市場。

　　Construction industry has been listed as one of the four pillar industries of national economy. During the Tenth Five-Year Plan period, the focus of investment is still infrastructure construction and residential industry. The real estate industry will continue to grow rapidly before 2010: in 2008, the completed area of township houses reached 482,000 square meters, using 183,000 tons of steel; in 2009, the completed area of township houses reached 513,000 square meters, using 19,000 tons of steel; in 2010, the completed area of township houses in China is estimated to reach 600,000 square meters, using 22,800 tons of steel. Large-scale construction projects provide a broad market for steel bar processing products.
