Embodiment Construction

[0036] The technical solutions of the embodiments of the present invention will be explained and described below in conjunction with the accompanying drawings of the present invention, but the following embodiments are only preferred embodiments of the present invention, not all of them. Based on the examples in the implementation manners, other examples obtained by those skilled in the art without making creative efforts all belong to the protection scope of the present invention.

[0037] In the present embodiment, the ground frame column 1 is changed to a method of a beam-on-column structure, such as Figure 1 to Figure 6 shown, including the following steps:

[0038] Step 1, install the upper and lower encircling column supports 2, 3: make the upper and lower encircling column supports 2, 3, and fix the completed upper and lower encircling column supports 2, 3 on the floor frame column 1, so that the upper and lower encircling column supports 2, 3 The encircling column ho...

Abstract

The invention discloses a method for changing a floor frame column to an on-beam column structure, and belongs to the technical field of house structural transformation. Aiming at solving the problemthat an existing method has difficulty in improving a load-bearing structure, according to the following adopted technical scheme, the method for changing the floor frame column to the on-beam columnstructure comprises the following steps: 1, an upper encircling column holder and a lower encircling column holder are mounted; 2, a tie structure is mounted; 3, a to-be-cut part is removed; 4, a newfixing structure is manufactured, specifically, a new floor and a new supporting beam are manufactured; and 5, other structures are removed. According to the method, the floor frame column is changedto the on-beam column structure, the established tie structure shares the bearing weight of the floor frame column, and thus the structure keeps stable in the demolition process; and the new floor andthe new supporting beam which are connected with anchoring steel bars into a whole are established to become a new load-bearing structure, the original floor frame column below a floor is removed, thus the lower part of the floor has a large space, and the structure keeps stable all the time in all the operating steps.

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...
