Partially prefabricated high-strength steel reinforced concrete cross-shaped column
The invention discloses a partially prefabricated high-strength steel reinforced concrete cross-shaped column. The partially prefabricated high-strength steel reinforced concrete cross-shaped column comprises a partially prefabricated high-strength steel reinforced concrete cross-shaped column shell and internal cast-in-place concrete, wherein the shell comprises prefabricated concrete and a cross-shaped steel-steel reinforcement framework; the cross-shaped steel-steel reinforcement framework comprises cross-shaped steel surrounded by stirrups and longitudinal bars; side wing steel plates are connected to the end parts of cross-shaped steel webs; the two sides of the side wing steel plates are connected through pattern steel plates and are welded at intersection nodes; and the internal cast-in-place concrete is poured in an internal cavity of the partially prefabricated high-strength steel reinforced concrete cross-shaped column shell. The partially prefabricated high-strength steel reinforced concrete cross-shaped column solves the problems of difficult hoisting and transportation and environmental pollution, reduces cracks generated by strength difference between the cast-in-place concrete and the prefabricated concrete, enhances the bonding structural strength and durability of post-poured concrete and a prefabricated part, is better in anti-seismic performance, and prominently improves the bearing capacity and the ductility.
本发明公开了一种部分预制装配的高强型钢混凝土十字形柱，包括部分预制装配的高强型钢混凝土十字形柱外壳和内部现浇混凝土；外壳包括预制混凝土和十字形型钢‑钢筋骨架；十字形型钢‑钢筋骨架包括箍筋和纵筋包围的十字形型钢，侧翼钢板连接在呈十字形的型钢腹板的端部，侧翼钢板两侧通过花纹钢板连接，并在交汇节点处焊接，内部现浇混凝土浇筑在部分预制装配的高强型钢混凝土十字形柱外壳内部空腔内。本发明解决了吊装运输困难、污染环境的问题；减少现浇与预制混凝土强度差产生的裂缝，增强后浇混凝土与预制部分的黏结结构强度和耐久性，抗震性能更好，柱的承载能力和延性得到显著提高。
