［摘要］提出了一種造樓機(jī)附墻裝置與剪力墻的連接構(gòu)造系統(tǒng)，該系統(tǒng)由造樓機(jī)軌道、剪力墻、連接軌道與剪力墻的螺桿及條形鋼板構(gòu)成。進(jìn)行了22個附墻裝置連接構(gòu)造試件的抗拉拔性能試驗(yàn)，試件變化參數(shù)包括墻體厚度、墻體配筋、墻體構(gòu)造、混凝土強(qiáng)度、墻體支點(diǎn)距離，其中墻體構(gòu)造包括預(yù)留圓孔貼靠正交分布鋼筋、預(yù)埋錨筋連接、附加鋼筋網(wǎng)片、預(yù)留圓孔不貼靠鋼筋，分析了其破壞特征、承載力、剛度和鋼筋應(yīng)變。結(jié)果表明：螺桿、錨筋及鋼板均未發(fā)生明顯損傷，試件的破壞形式為墻體彎剪破壞；提高混凝土強(qiáng)度，增加墻體厚度、墻體配筋，減小墻體支點(diǎn)距離均可提高試件的承載力和剛度；預(yù)留圓孔貼靠正交分布鋼筋試件的受力性能明顯好于預(yù)留圓孔不貼靠鋼筋試件；提出的造樓機(jī)附墻裝置與剪力墻的預(yù)留圓孔貼靠正交分布鋼筋連接構(gòu)造工作性能可靠。

Abstract:A connection structure system for the connection between the wall-attaching device of the building construction machine and the shear wall was proposed. The system consists of building construction machine track, shear wall, bolts and strip steel plates connecting track and shear wall. The anti-drawing performance test was conducted of 22 specimens with connection structure of wall-attaching device. Test parameters were the thickness of the wall, the reinforcement of the wall, the structures of the wall, the strength of the concrete, and the wall fulcrum distance. The structures of the wall include reserved round holes against orthogonally distributed steel bars, pre-embedded anchor bars connection, attached steel mesh, and reserved round holes far from steel bars. The failure characteristics, bearing capacity, stiffness and steel bars strain of specimens were analyzed. The results indicate that there is no obvious damage on the bolts, the anchor bars and the steel plates, and the failure mode of the specimens is bending-shear failure of wall; It can improve the bearing capacity and rigidity of the specimen by increasing concrete strength, increasing wall thickness, wall reinforcement, and reducing wall fulcrum distance; The mechanical performance of the specimen with the reserved circular hole attached to the orthogonally distributed steel bar is significantly better than the specimens with reserved round holes far from attached steel; The proposed building machine wall attachment device with the reserved round holes of the shear wall attached to the orthogonally distributed steel bars to connect the structure has reliable working performance.
