Prefabricated building cantilever scaffold steel beam fixing node construction device and construction method thereof
The invention discloses a prefabricated building cantilever scaffold steel beam fixing node construction device and a construction method thereof. The construction device comprises U-shaped pull ringsand counter-pressure steel beams, the counter-pressure steel beams press the inner anchoring end of a cantilever steel beam, the portions, at the fixing end of a cast-in-situ reinforced concrete beam, of the counter-pressure steel beams are fixed through the U-shaped pull rings embedded in the cast-in-situ reinforced concrete beam, external thread sections are arranged at the two ends of the U-shaped pull rings, sequentially penetrate through connecting holes in the counter-pressure steel beams at the inner fixing end and angle steel pressing plates and are connected to nuts, the portions, atthe fixing end of a cast-in-place shear wall, of the counter-pressure steel beams are anchored into reserved openings of the cast-in-place shear wall, and gaps between the cantilever steel beam and the U-shaped pull rings and a gap between the cantilever steel beam and the cast-in-place shear wall are filled with wood wedges. The construction device has the advantages that the structure is reasonable, a stress system is clear, and the structural integrity and the appearance quality of a prefabricated laminated plate are guaranteed. The construction method has the advantages that the materialutilization rate is high, the safety and reliability are achieved, the implementation is facilitated, the structural integrity and the appearance quality of the prefabricated laminated plate are guaranteed, the construction period is shortened, and the cost is saved.
本发明公开一种装配式建筑悬挑脚手架钢梁固定节点施工装置及其施工方法，施工装置包括U型拉环和反压钢梁，反压钢梁压设在悬挑钢梁的内锚固端上，反压钢梁在现浇钢筋混凝土梁的固定端处利用预埋在现浇钢筋混凝土梁内的U型拉环固定，U型拉环的两端具有外螺纹段、且分别依次穿过在内固定端上的反压钢梁与角钢压板上的连接孔，外螺纹段与螺帽连接，反压钢梁在现浇剪力墙的固定端处锚入现浇剪力墙的预留洞口内；悬挑钢梁与U型拉环及现浇剪力墙之间的缝隙内填充有木楔；其结构合理，受力体系明确，保证预制叠合板结构完整性及外观质量；其施工方法材料利用率高，安全可靠，利于实施，保证预制叠合板结构完整性及外观质量，节约工期、节省成本。
