钢筋与砼成品保护措施施工技术交底.doc

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.楼板钢筋采用双面钢筋时，应加足够的钢筋凳以保护底、面网筋的间距，并用木板等物在钢筋面铺设必要的临时走道，施工人员须沿过道行走，必要时可沿梁位，尽量不要踩踏板筋，特别是支座负筋。
    6.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。
7.对于剪力墙钢筋，安装模板时，不能由于钢筋绑扎偏位或埋管件而随便割除钢筋，应经技术人员

    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. Slabs reinforced with double-sided bar, the bar stool should be added enough to protect the bottom and surface mesh reinforcement spacing, and reinforced with wood and other materials necessary temporary walkway paved surfaces, construction workers have to walk along the aisle, if necessary along the beam position, try not to pedal reinforcement, especially bearing negative reinforcement.
    6. Pouring concrete, the concrete application of bar stool branch duct, the tube may not be, removed litter, should light up.
7. The wall reinforcement, installation template, not as steel banding deviation readily removed or buried pieces of steel, shall be subject to technical staff
