Fabricated beam-beam section steel connecting joint and construction method thereof
The invention discloses a fabricated beam-beam section steel connecting joint and a construction method thereof. The fabricated beam-beam section steel connecting joint comprises a left prefabricated steel beam, a right prefabricated steel beam, a welding seam and high-strength friction type bolts, left pre-embedded section steel is arranged on the end part of the left prefabricated steel beam, and right pre-embedded section steel is arranged on the end part of the right prefabricated steel beam. The beams are connected through a connecting device to form a section of safe and reliable frame beam, the connecting device comprises upper longitudinal bars, lower longitudinal bars, stirrups, two sections of embedded section steel and high-strength friction type bolts, the upper longitudinal bars and the lower longitudinal bars are welded on a front side plate, a rear side plate and a web plate of the section steel in a lap joint mode, and the stirrups improve the reliability of a section steel structure in a densification mode. The two sections of embedded section steel are special section steel manufactured in advance in a factory, the two sections of prefabricated steel beams are connected through a bolt welding combination method, and then reliable beam connection is guaranteed. The dry operation construction is carried out in the whole course, post cast concrete is not needed, construction is simple, the period is short, on-site construction and assembly are convenient, the influence of the environment is small, and the fabricated beam-beam section steel connecting joint can be applied to construction in winter.
本发明公开了一种装配式梁梁间型钢连接节点及其施工方法。该连接节点包括左预制钢梁、右预制钢梁、焊缝、高强摩擦型螺栓，左预制钢梁的端部设置有左预埋型钢，右预制钢梁的端部设置有右预埋型钢。梁之间通过连接装置连接，形成一段安全可靠的框架梁，连接装置包括上部、下部纵筋、箍筋、两段预埋型钢以及高强摩擦型螺栓，上、下部纵筋搭焊在型钢前侧板、后侧板及腹板上，箍筋通过加密的方式提高型钢结构的可靠性，两段预埋型钢是工厂预先制作的特殊型钢，两段预制钢梁通过栓焊结合的方法连接，进而保证梁连接可靠。全程干作业施工，无需后浇混凝土，施工简单、周期短，便于现场施工组装，受环境的影响较小，可应用于冬季施工。
