Embodiment Construction
[0031] The specific practice of the present invention is described in detail below. The technical requirements for frame column replacement preparation, construction technical requirements for hoisting, technical requirements for section steel rolling and welding construction, technical requirements for on-site grouting construction, etc. will not be repeated in the frame structural column assembly replacement method of the present invention. The following focuses on the implementation cases of the methods involved in the present invention.
[0032] like figure 1 As shown, the frame structure column assembly replacement method includes the following construction steps:
[0033] 1) Construction preparation: Prefabricate frame columns 54 and rigid connecting bars 44, and prepare materials and devices required for construction;
[0034] 2) Arrangement of the support conversion system: set the lower brace 4 and the upper brace 5 on the lower frame column 2 and the upper frame colu...

The invention discloses a frame structure column assembly type replacement method. The method comprises the following construction steps that construction preparation is conducted; laying a support conversion system; removing the frame column to be replaced; frame column auxiliary supports to be replaced; arranging stiff connecting ribs; support changing frame columns are installed and fixed; and the column top grouting body is constructed. The interlayer supporting columns and the to-be-replaced frame columns are used for jointly supporting the structural load, and the engineering measure cost is saved; the to-be-replaced frame column is replaced by the support replacing frame column, so that the construction efficiency is improved; stiff connecting ribs, rib top sliding grooves and side face connecting tenons are arranged at the bottom ends of the support changing frame columns, connecting reinforcing ribs and reinforcing angle ribs are arranged at the top ends of the support changing frame columns, and the stress performance of the support changing frame columns is improved.
Description
technical field [0001] The invention relates to a construction method of a frame structure column in a building construction project, in particular to an assembled replacement method for a frame structure column. Background technique [0002] In the process of building construction or use, the problem of insufficient bearing capacity of frame columns is often encountered. In the process of improving the bearing capacity of frame columns, how to improve the integrity of the structure, improve the load-bearing performance of the structure, and reduce the difficulty of construction are often the focus and difficulty of engineering construction control. [0003] At present, the method of increasing the cross-section or sticking steel is usually used in the project to improve the bearing capacity of the active frame column, which usually includes the following construction steps: first set up the full support between the floors, then remove the concrete on the surface of the fram...
