Construction method of section steel column concrete beam-column joint

Abstract

The invention discloses a construction method of a section steel column concrete beam-column joint. The construction method comprises the following steps: S1, the section sizes of section steel beamskeep consistent; S2, a drawing provided by design is deepened, and then design review is conducted; S3, a section steel skeleton of a column is mounted; S4, the section steel skeleton of the column ismachined; S5, the positions, encountering webs, of face bars are constructed; and S6, the beam-column joint and the lower parts of section steel flanges of the beams are constructed. The positions, encountering the webs, of the face bars, and the positions, encountering the flanges, of the face bars are constructed; the positions, encountering the webs, of the face bars are constructed accordingto the steps: stiffening plate welding, hole forming and penetrating of two/three rows of steel bars, and hole forming in the webs in a factory; the positions, encountering the flanges, of the face bars are constructed according to the steps: bracket welding, and machining of two/three rows of steel bars; bottom bars of the beam-column joint adopt steel bar anchor plates; and because of improvement of the construction method, on-site construction operation can be convenient, input of the construction amount and labor force is lowered, the total construction progress is accelerated, the construction period is shortened, and the construction cost is lowered.

Description

technical field [0001] The invention relates to the technical field of steel-reinforced concrete, in particular to a construction method for steel-column concrete beam-column joints. Background technique [0002] The steel reinforced concrete rigid structure can not only meet the stress requirements of high-rise and long-span structures, but also meet the fire protection requirements of buildings. However, the disadvantages of this type of structure are that the joints between the steel column and the concrete beam are complicated, the construction is difficult, and the construction quality is difficult to guarantee. Therefore, the connection between the steel bar and the steel bar in the rigid structure becomes the most important thing in the construction. [0003] The dense steel bars at the bottom of the beam are not suitable for construction, and the joints of the steel bone columns are deepened. In the actual construction site, there will be structural stress problems d...

Problems solved by technology

However, the disadvantages of this type of structure are that the joints between steel columns and concrete beams are complex, the construction is difficult, and the construction quality is difficult to guarantee. Therefore, the connection between steel bars and steel bars in rigid structures has become the top priority in construction.

[0003] The dense steel bars at the bottom of the beam are not suitable for construction, and the joints of the steel bone columns are deepened. In the actual construction site, there will be structural stress problems due to the insufficient connection and anchorage of the steel columns and beam steel bars.
