圓鋼的理論計算公式
分類
圓鋼是指截麵為圓形的實心長條鋼材。其規格以直徑的毫米數表示,如"50"即表示直徑為50毫米的圓鋼。
圓鋼分為熱軋、鍛制和
冷拉三種。熱軋圓鋼的規格為5.5-250毫米。其中:5.5-25毫米的小圓鋼大多以直條成捆供應,常用作鋼筋、
螺栓及各種機械零件;大於25毫米的圓鋼,主要用於制造機械零件或作
無縫鋼管坯
圓鋼與其它鋼筋的區別:1 外型不一樣,圓鋼外型光圓,無紋無肋,其它鋼筋表麵外型有刻紋或有肋,這樣就造成圓鋼與混凝土的粘結力小,而其它鋼筋與混凝土的粘結力大。 2 成份不一樣,圓鋼(一級鋼)屬於普通
低碳鋼,其它鋼筋多為合金鋼。3
強度不一樣,圓鋼強度低,其它鋼強度高,即直徑大小相同的圓鋼與其它鋼筋相比,圓鋼所能承受的拉力要比其它鋼筋小,但圓鋼的塑性比其它
鋼筋強,即圓鋼在被拉斷前有較大的變形,而其它鋼筋在被拉斷前的變形要小得多。
