交底內(nèi)容:
1加工成型的鋼筋應(yīng)按規(guī)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(yīng)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(diào)整變形,影響鋼筋的綁扎的質(zhì)量。
5.澆灌砼時,砼輸送管應(yīng)用鋼筋凳支起,拆管時不得將管亂拋,應(yīng)輕放。
6.鋼筋綁扎后,應(yīng)盡快驗收并澆筑砼,防止暴露時間過長,造成銹蝕或人為破壞。
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.
