技术交底——地下室钢筋绑扎工艺标准（Technical disclosure - basement reinforcement banding standard） Two, the reinforcement assembling and installation engineering Steel banding process standards 4-6 basement (406-1996) The range of 1 This technology is applicable to steel banding basement floor, wall of reinforced concrete. 2 construction preparation The 2.1 main materials and equipment: 2.1.1 bar: should have the certificate, according to the provisions for mechanical test. When the brittle fracture and other special circumstances occur during the machining process, the need for chemical composition analysis. There should be no old rust and dirt. 2.1.2 wire: can use 20 ~ 22 wire (fire wire) or galvanized wire (Qian Si). The wire cutting length to meet the requirement of operation. The protective layer of concrete with 2.1.3 control mortar pad, plastic card, hook or rod etc.. 2.1.4 tools: steel hook, crowbar, wrench, lashing wire rack, brushes, trolleys, chalk and rulers. 2.2 operating conditions: According to the provisions of 2.2.1 plan construction site location, reinforced yard clean, smooth. Ready to stow according to rebar order classification and cleaning, corrosion. 2.2.2 check the reinforcement level, type, shape, size and quantity are the same with the single design drawings and processing ingredients. 2.2.3 when the high underground water level construction site, must have drainage and dewatering measures. 2.2.4 familiar with the drawings, in order to determine the reinforcement with, and do the work in conjunction with the relevant types, such as formwork, pipeline, waterproof construction and assembling reinforcement relationship, construction method, make technical disclosure. 2.2.5 according to the basement waterproof construction scheme (by sticking plaster or construction), floor reinforcement binding finish bottom waterproof layer and a protective layer; a bottom end around the template (or end wall masonry protection, waterproof layer). When used in the basement wa
