The technical solution adopted by the present invention to solve the technical problem is: steel-concrete composite structure without welded node connectors, including steel columns, ring plates and more than one corbel, the ring plates and steel columns are welded together, and more than one The corbels are respectively welded with the ring plate or processed as a whole, and the top plate and/or bottom plate of each corbel are designed with steel bar connectors for installing steel bars.

In the above technical solution, the steel bar connector includes a mounting plate on which more than one through hole for the steel bar to penetrate is designed; the steel bar connector includes more than two stiffening plates for force transmission, The stiffening plates are respectively welded with the mounting plates.

On each corbel, more than one hoop plate is designed to replace the beam stirrup; between the top plate of the corbel and the hoop plate, a backing plate for reinforcing and supporting is designed.

The steel column is welded with the connecting plate of the second row of ribs at the bottom of the beam, and the connecting plate of the second row of ribs at the bottom of the beam is welded with a steel bar connector for installing steel bars. For the case of multiple rows of beam bars, the welded connecting plate can also be used to add steel bars way of the connector.

The steel column is in the shape of a round tube, a square tube, an I-beam or other shapes.

The beneficial effect of the present invention is: because the present invention is designed with the reinforcing bar connector that is used to install reinforcing bar on the top board and/or the bottom plate of each corbel, so the present invention has following several advantages: 1, integrity is good: processing plant will The steel bar connector and the steel structure are welded together, and the steel bar and the steel structure are connected together by mechanical connection, and its integrity is good; 2. Saving materials: the steel bar connector does not need reinforcement and other measures, the length of the corbel is short, and the overall The amount of steel used is greatly reduced, and the materials used are small pieces of steel, and the leftovers from the processing plant can be used to process steel connectors; 3. Convenient construction: no welding at the construction site is required, and mechanical connections are used, which are not affected by weather and other factors , the construction is convenient and flexible, and the construction quality is easy to be guaranteed; 4. Clear force transmission: the mechanically connected steel bars directly act on the corbels, which will not cause additional local tearing force on the steel column wall, and the overall force is uniform; 5. Energy saving Emission reduction: reduce the workload of on-site welding and electricity consumption, thereby reducing the consumption during the construction process, saving construction costs, and reducing exhaust gas emissions, etc.
