Composite-concrete-steel double-wall hollow pipe column fabricated joint and construction method thereof
The invention relates to a composite-concrete-steel double-wall hollow pipe column assembly type joint which comprises a prefabricated column, a reinforced concrete foundation/cover beam and a high-strength non-shrinkage mortar layer. The prefabricated column comprises a composite pipe, a steel pipe and a concrete layer, the steel pipe is sleeved with the composite pipe, concrete is filled between the composite pipe and the steel pipe to form the concrete layer, and one end of the steel pipe extends out of one end of the composite pipe; a metal corrugated pipe is pre-buried in the reinforced concrete foundation/bent cap; the end, extending out of the composite pipe, of the steel pipe is inserted into the metal corrugated pipe, and high-strength non-shrinkage mortar is poured between the metal corrugated pipe and the steel pipe to form a high-strength non-shrinkage mortar layer. The invention further relates to a construction method of the composite-concrete-steel double-wall hollow pipe column assembly type joint. The combined structure fabricated building has the advantages of being clear in force transmission path, good in ductility, high in integrity, excellent in anti-seismic property and controllable in joint quality, and belongs to the technical field of combined structure fabricated buildings.
本发明涉及一种复材‑混凝土‑钢双壁空心管柱装配式节点，包括预制柱、钢筋混凝土基础/盖梁、高强无收缩砂浆层；预制柱包括复材管、钢管、混凝土层，复材管套在钢管外，复材管和钢管之间填充混凝土形成混凝土层，钢管的一端从复材管的一端伸出；钢筋混凝土基础/盖梁内预埋金属波纹管；钢管从复材管中伸出的一端插入金属波纹管中，金属波纹管和钢管之间灌注高强无收缩砂浆形成高强无收缩砂浆层。还涉及一种复材‑混凝土‑钢双壁空心管柱装配式节点的施工方法。本发明具有传力路径清晰、延性好、整体性高、抗震性能优良以及节点质量可控的优点，属于组合结构装配式建筑技术领域。
