在钢筋混凝土结构中,为了保证构造物强度,改善密集的钢筋布置,广泛采用变形钢筋。变形钢筋在施工过程中将随着构造物的建造要进行接头间的连接。目前,钢筋连接的常用方法有搭接绑扎、搭接电弧焊、电渣压力焊,气压焊等。绑扎法简单,施工方便、但浪费钢材,不能承受由于轴向力偏心产生的附加
In the reinforced concrete structure, in order to ensure the strength of the structure and improve the dense steel arrangement, deformed steel bars are widely used. In the construction process, deformed rebars will be connected with the joints as the structures are constructed. At present, the common methods used for the connection of steel reinforcements are overlap bonding, overlap arc welding, electroslag pressure welding, and pressure welding. The tying method is simple, the construction is convenient, but the steel is wasted, and it cannot withstand the additional effect due to the eccentricity of the axial force.
