交底内容:
    1加工成型的钢筋应按规格品种堆放整齐。当用垫木垫起时,需安放足够的垫木,保证钢筋不被压弯变形。
    2.成型钢筋的运输保护。成型钢筋在装车及卸车的过程应按注意保护,分类捆扎装车;当采用人工卸车时不能乱抛钢筋,造成变形。
    3.成型钢筋需堆放较长时间时,须注意防雨,防止钢筋锈蚀。
    4.由于采用逆作法施工,在往下输送钢筋时,不得采用人工抛掷,造成钢筋难以调整变形,影响钢筋的绑扎的质量。
    5.浇灌砼时,砼输送管应用钢筋凳支起,拆管时不得将管乱抛,应轻放。
 6.钢筋绑扎后,应尽快验收并浇筑砼,防止暴露时间过长,造成锈蚀或人为破坏。
Cards on the table contents:
    A processing specification forming species should be stacked neatly reinforced. When paving with skids, the skids to be placed sufficient to ensure the bar is not bending deformation.
    2. Shaping the transportation reinforced protection. Reinforcement steel in the process of loading and unloading should be attention to the protection, classification bundle loading; when the artificial can not throw when unloading steel, resulting in distortion.
    3. Forming stacked bar take a longer time, to pay attention to rain, to prevent steel corrosion.
    4. As a result of reverse construction, the down transmission reinforcement shall not use artificial throw, resulting in deformation of steel difficult to adjust, affecting the quality of steel for banding.
    5. Pouring concrete, the concrete application of bar stool branch duct, the tube may not be, removed litter, should light up.
 6. Steel banding soon as possible after acceptance, and pouring concrete, to prevent the exposure time is too long, resulting in corrosion or vandalism.
