钢筋混凝土钢管组合柱施工的质量控制

CONTROL ON CONSTRUCTION QUALITY OF RC STEEL PIPE COMPOSITE COLUMN

深圳诺德中心大厦为超高层建筑,其15层以下框架柱采用钢筋混凝土钢管组合柱。施工中采用拉线透视方法、吊线法进行质量控制,效果较好。组合柱的混凝土施工应先钢管内,再钢管外。钢管内混凝土施工应严格过程控制。施工组织应满足钢管内混凝土质量检查的要求。竖向构件水平施工缝留设的位置应避开钢管柱水平加劲肋,并应位于其下侧位置。

Shenzhen Norde Center Mansion is a pipe column is used as frame PoSt control quality in the construction, super-high-rise building where reinforced concrete steel in under floor 15. Perspective method achieving a good effect. The composite from inside the steel pipe to the outside. And the strictly controlled while the construction organization and plumbing method are used to column concrete should be placed construction process of concrete inside the pipe should be should satisfy the concrete quality inspection requirement inside the pipe. The horizontal joints in the vertical structure members should be arranged away from and under the horizontal ribs of the steel pipe column.
