Large-section stiff steel beam reverse construction method
The invention discloses a reverse construction method for a large-section stiff steel beam, and belongs to the technical field of building construction. The installation of the steel reinforced concrete beam is prior to the pouring of the steel reinforced concrete, namely, the construction is performed by adopting the reverse construction method, on one hand, the installation of the steel reinforced concrete beam is not influenced by the steel reinforced concrete column, so that the installation precision of the steel reinforced concrete beam is effectively ensured; and on the other hand, by taking the installed steel reinforced concrete beam as a reference, the column main reinforcements of the steel reinforced concrete column can accurately penetrate through the flange preformed holes of the steel reinforced concrete beam in the installation process, so that the positioning of the column reinforcements and the control of the distance between the column reinforcements can be ensured.
本发明公开了一种大截面劲性钢梁逆作法施工方法，属于建筑施工技术领域。将型钢混凝土梁的安装先于型钢混凝土的浇筑，即采用逆作法进行施工，一方面，型钢混凝土梁的安装不受型钢混凝土柱的影响，从而有效保证了型钢混凝土梁的安装精度；另一方面，以安装完成的型钢混凝土梁为基准，型钢混凝土柱的柱主筋在安装过程中能够精准穿过型钢混凝土梁翼缘预留孔，有利于保证柱筋定位及柱筋间距的控制。
