A Method for Changing Floor-to-ceiling Frame Columns to Beam-on-Column Structures

Abstract

The invention relates to a method for changing a floor-standing frame column to a beam-on-column structure, which belongs to the technical field of house structure transformation. Aiming at the problem of difficulty in improving the load-bearing structure in existing methods, the technical solution is as follows: a method for changing a floor-to-ceiling frame column to a beam-on-column structure , including the following steps: Step 1, install the upper and lower encircling column supports; Step 2, install the tie structure; Step 3, remove the part to be cut; Step 4, make a new fixed structure: make a new floor slab and a new support beam; 5. Remove the rest of the structure. The method of the present invention changes the floor frame column into a beam-on-column structure, and the established tie structure shares the bearing weight of the floor frame column, so that the structure remains stable during the demolition process, and a new floor slab and a new support beam integrated with the anchoring steel bar are established to become a new structure. The load-bearing structure removes the original landing frame column under the floor, so that a larger space is obtained under the floor, and a relatively stable structure is always maintained in each operation step.

Description

technical field [0001] The invention belongs to the technical field of house structure transformation, and in particular relates to a method for changing a floor-to-ceiling frame column into a beam-on-column structure. Background technique [0002] With people's continuous pursuit of a better life, or the continuous changes in the use and function of old houses, it is often necessary to renovate old houses. But usually only the non-load-bearing structures such as enclosure walls, partition walls, and decorations are transformed. There are not many cases involving changes in the structural system, especially for the transformation of the load-bearing system of the frame columns of high-rise frame structures. There are few methods for reference. Case: In a 15-storey high-rise frame structure office building in the 1990s, the column spacing at the main entrance and exit is 3.6 meters. According to the current use requirements, the space feels crowded and the comfort is poor. T...
