Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
As shown in fig. 1 to 3, the newly-added concrete beam connection structure for the existing concrete column comprises a steel plate 2 which is pre-embedded on the existing reinforced concrete column 1, and a plurality of first studs 5 are fixedly welded on the steel plate 2. The welding has a plurality of sleeves 4 on the steel sheet 2, and the grafting is fixed with construction reinforcing bar 10 on the sleeve 4 on upper portion, and construction reinforcing bar 10 is four, and the grafting is fixed with roof beam level armpit lower part reinforcing bar 8 on the sleeve 4 of lower part, the middle part of steel sheet 2 is fixed with accepts girder steel 3, and accepts girder steel 3 and is located between the construction reinforcing bar 10, accepts girder steel 3 and accepts the girder steel for the I-shaped, and the last face that the girder steel was accepted to the I-shaped has a plurality of second pegs 16 with the fixed welding of equipartition on the face down.
The second stirrups 13 are horizontally arranged between the construction bars 10.
