Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. While the invention will be described in conjunction with the preferred embodiments, it will be understood that it is not intended to limit the invention to the described embodiments. On the contrary, the invention is to cover alternatives, modifications and equivalents, which may be included within the scope of the invention as defined by the appended claims.

[0028] Such as Figure 1~3 As shown, the present invention includes the original concrete column and the shaped steel column. The original concrete column 10 has a concrete label of C30, a diameter of 600mm, a longitudinal bar diameter of 18mm, and a protective layer thickness of 25mm. The shaped steel column 1 is Q235 H-shaped steel, with a height of 200mm, a width of 200mm, a web thickness of 8mm, and a thickness of the wing plate of 12mm.

[0029] The concrete at the top of the end of the ori...

Abstract

The invention relates to a construction method for connecting a steel pipe concrete column connection structure to a reinforced concrete column. The construction method is suitable for a floor raising and rebuilding project. A separation type tightening protection barrel is arranged at the end part of an original column, and three tightening rings are arranged on the protection barrel and are anchored by bolts; the bottom end of a section steel column is arranged at the middle part position of the separation type tightening protection barrel; a connection steel plate is arranged at the bottom of the section steel column, and two reinforcement ribs welded with the connection steel plate are symmetrically arranged on a web plate of the section steel column; a plurality of holes are pre-drilled in the connection steel plate, so that longitudinal ribs, which are exposed after concrete at a certain height is drilled off, of the original column can pass through and are welded with the connection steel plate through welding nuts. The construction method is high in construction speed and high in connection strength and has higher technical economical benefits.

Description

technical field [0001] The invention relates to a construction method of a reinforced concrete column top-connected steel column connection structure, which is suitable for floor heightening and reconstruction projects, and belongs to the technical field of house construction engineering. Background technique [0002] The shaped steel column is a composite member embedded in the concrete column, and the shaped steel column is used as the main load-bearing member of the building. Compared with ordinary reinforced concrete columns, although the amount of steel used is slightly larger, the steel column has good deformation and earthquake resistance. And in the construction process, the section steel has a large bearing capacity and can be used as a scaffold. At this stage, the commonly used steel column in my country is the steel concrete column, and the steel concrete column is poured concrete on the periphery of the steel. [0003] For floor heightening and reconstruction p...
