一、前言 随着我国建筑业的发展,现浇钢筋混凝土框架结构迅速增加,传统的钢筋连接方法——绑扎和搭接焊已远不能适应建筑工程的需要,因此,近年来一些地方和单位进行了探索,有的采用了钢筋电渣焊接方法,有的采用了钢筋气压焊技术,使得钢筋连接方法有所改进。气压焊虽然具有不用电、横向竖向都能焊接的特点,但所需辅助设备多,钢筋端都要求较高,工效低,而且对操作者经验的依赖性大。 I. INTRODUCTION With the development of China’s construction industry, the cast-in-place reinforced concrete frame structure has rapidly increased. The traditional method of reinforcing steel connections—ligation and lap welding—is far from meeting the needs of construction projects. Therefore, in recent years, some localities and units have conducted In the exploration, some have adopted the electroslag welding method of reinforced steel, and some have adopted the steel bar pressure welding technology, which has improved the connection method of steel bars. Although gas pressure welding has the characteristics of no electricity and horizontal and vertical welding, it requires many auxiliary equipments, high rebar requirements, low work efficiency, and great dependence on operator experience.
