Embodiment Construction
[0031] The specific practice of the present invention is described in detail below. The technical requirements for the preparation and construction of the replacement support frame column, the technical requirements for the hoisting construction, the technical requirements for the rolling and welding construction of section steel, the technical requirements for the field grouting construction, etc., will not be repeated in the assembled replacement method of the frame structure column 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 in the figure, the assembled replacement method of the frame structure column includes the following construction steps:
[0033] 1) Construction preparation: prefabricate the supporting frame column 54 and the rigid connecting bar 44, and prepare the materials and devices required for the construction;
[0034] 2) Arrangement of the support...

The invention discloses an assembled replacement method for a frame structure column, comprising the following construction steps: construction preparation; arrangement of a support conversion system; removal of a frame column to be replaced; auxiliary support of the frame column to be replaced; The column is installed and fixed; the top of the column is constructed by grouting. The invention adopts the interlayer support column and the frame column to be replaced to jointly support the structural load, which saves the cost of engineering measures; replaces the frame column to be replaced with the replacement support frame column, and improves the construction efficiency; Connecting ribs, rib top chutes and side connecting falcons are provided with connecting reinforcing ribs and reinforcing angle ribs at the top, which improves the mechanical performance of the frame column for replacement.
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 of 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 the frame column, how to improve the integrity of the structure, improve the bearing performance of the structure, and reduce the difficulty of construction is often the focus and difficulty of engineering construction control. [0003] At present, increasing the cross-section or sticking steel method 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 the inter-story full hall support, then remove the concrete on the surface of the frame column, and th...
