The general method of connecting steel bar and concrete beam is 1) steel bar with a slope of 1:6 around the steel column wing, continuous placement of steel bar; 2) Steel bar welding connection of steel bone column flange (steel bone column flange can be divided into TWO types: H-section steel and T-section steel) steel bar welding sleeve of steel bone column flange, on-site mechanical connection.

One kind of treatment is the reinforcement processing, which can be applied to the narrow width of the wing plate and the small diameter of the steel bar, but in the case of the large diameter of the steel bar, the site construction is more difficult.

The second is the use of welding connection, this connection because of the shape of the leg, the difficulty of processing nodes is different; The third is the use of T-shaped steel leg, this connection mode of welding H-shaped steel connection node adopts T-shaped steel leg, its length and steel column outer concrete thickness and steel bar specifications.

Three is the use of casing connection, casing connection of the processing accuracy of equipment and the installation accuracy of the site have high requirements, for the upper and lower steel bars, the number of layers of concrete beams more than two layers, and the connection of the steel reinforced column using T-shaped steel leg and sleeve combination connection.

The general treatment of welding connection between steel bar and H-beam is as follows: 1 section steel column web factory reserved piercing holes, continuous arrangement of steel bars; Section 2 steel column web is provided with lap plate, welded with steel bar connection.

The first treatment method is to use reserved reinforcement holes, for the construction unit, this method saves time and effort, but in the web reserved reinforcement holes on the web section of steel column loss; In engineering structure design, the loss of web section should not exceed 15%. 

The second is the use of welding connection, the web area of the steel bar and the web on the reinforcement plate welding connection, this method is derived from the wing area welding connection, its premise is to meet the welding length of steel bar and weld quality.

Steel reinforced column deepening design relative to the pure steel structure, the difficulty will increase many, because the civil aspects of knowledge is the "short board" of many detail of engineers, many practical engineering of nodes at the same time, in the design, specification and images on did not give a specific node, hope this article can provide some help to you, in the structure of the reinforced column JinJie construction and deepening the design.
