鋼筋與砼成品保護措施施工技術交底.doc

交底內容:
    1加工成型的鋼筋應按規格品種堆放整齊。當用墊木墊起時，需安放足夠的墊木，保證鋼筋不被壓彎變形。
    2.成型鋼筋的運輸保護。成型鋼筋在裝車及卸車的過程應按注意保護，分類捆扎裝車；當采用人工卸車時不能亂拋鋼筋，造成變形。
    3.成型鋼筋需堆放較長時間時，須注意防雨，防止鋼筋銹蝕。
    4.由于采用逆作法施工，在往下輸送鋼筋時，不得采用人工拋擲，造成鋼筋難以調整變形，影響鋼筋的綁扎的質量。
    5.樓板鋼筋采用雙面鋼筋時，應加足夠的鋼筋凳以保護底、面網筋的間距，并用木板等物在鋼筋面鋪設必要的臨時走道，施工人員須沿過道行走，必要時可沿梁位，盡量不要踩踏板筋，特別是支座負筋。
    6.澆灌砼時，砼輸送管應用鋼筋凳支起，拆管時不得將管亂拋，應輕放。
7.對于剪力墻鋼筋，安裝模板時，不能由于鋼筋綁扎偏位或埋管件而隨便割除鋼筋，應經技術人員

    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
