Construction method of embedded steel bar connecting sleeve assembly
The invention discloses a construction method of an embedded steel bar connecting sleeve assembly, which comprises the following steps of: 1, before construction or in the construction process, assembling a connecting sleeve, a protective plug and a connecting steel bar into a whole; during bridge floor or tunnel base construction, it is guaranteed that the top face of the protection plug is flush with or slightly higher than the beam face or the concrete surface of the tunnel base; secondly, concrete surface layer milling treatment is conducted on the beam surface or the tunnel base, the milling depth is not smaller than 10 mm, all the protective plugs of the pre-buried connecting sleeves should be exposed after milling is completed, then the milled protective plugs are taken out, and then the rear connecting ribs are screwed in; the connecting sleeve is of an inverted-cone-shaped structure or a cylindrical structure with a fixing ring. According to the sleeve, the contact area between the sleeve and concrete can be increased, the cohesive force, the bond stress and the pulling resistance between the sleeve and the concrete are improved, and the stability of the sleeve embedded in the concrete is guaranteed.
本发明公开了一种预埋钢筋连接套筒组件的施工方法，包括步骤一：在施工前或施工过程中，将连接套筒、防护塞和连接钢筋组装为一体；在桥面或隧道基底施工中，保证防护塞顶面与梁面或隧道基底混凝土表面平齐或稍高；步骤二：对梁面或隧道基底进行混凝土表层铣刨处理，铣刨深度不小于10mm，铣刨完后应露出所有预埋连接套筒的防护塞，然后取出铣刨后的防护塞，然后旋入后连接筋；连接套筒为倒锥型结构或具有固定环的筒状结构。该套筒可增大与混凝土间的接触面积，提高套筒与混凝土之间的粘结力、握裹力和抗拔力，保证套筒预埋在混凝土中的稳定性。
