Description

Technical Field

[0001] This application relates to a composite reinforced concrete structure. Background Technology

[0002] Due to its high strength and excellent mechanical properties, reinforced concrete structures are widely used in public and residential buildings. Beam-column structures are the most commonly used structural form for effectively transferring wall loads and internal loads. With the increasing variety of building structures, composite structures combining steel and concrete are becoming more popular. These structures not only possess the advantages of rapid assembly and strong seismic performance of steel structures but also fully utilize the advantages of reinforced concrete. However, existing structures have certain problems in the connection between steel beams and concrete columns, with the reinforcing bars prone to breakage. Therefore, structural improvements are needed to avoid these issues. Utility Model Content

[0003] To address the aforementioned problems, this application proposes a composite reinforced concrete structure, comprising a reinforced concrete column and a steel structural beam disposed on the side of the column. The reinforced concrete column includes several annularly arranged reinforcing bars, and the steel structural beam includes two opposing vertical steel plates, through which the annular reinforcing bars pass. This application achieves a better connection between the reinforced concrete column and the steel structural beam by connecting the annular reinforcing bars that make up the column to the steel structural beam. Due to this structural integration, the connection will not cause potential problems such as the reinforcing bars breaking during use.

[0004] Preferably, a central square steel bar is provided in the middle of the reinforced concrete column, and the vertical steel plate abuts against the outer side of the central square steel bar. A separating angle steel bar is provided between the annular steel bar and the central square steel bar, and the separating angle steel bar is vertically positioned within the gap formed by the annular steel bar between the central square steel bar and the vertical steel plate; the opening of the separating angle steel bar faces the central square steel bar and the vertical steel plate. This application provides a separating angle steel bar between the central square steel bar and the annular steel bar. The separating angle steel bar serves to ensure the overall strength of the framework, and while ensuring the strength of the framework, it also prevents deformation of the annular steel bar at this location, thus ensuring structural strength.

[0005] Preferably, the annular reinforcing bars are arranged at four corners, with vertical reinforcing bars at each of the four corners, and outer protective concrete blocks are provided on the outside of the annular reinforcing bars, with the isolation angle steel embedded in the outer protective concrete blocks.

[0006] Preferably, the vertical reinforcing bars are composed of a combination of several vertical bars.

[0007] Preferably, the inner side of the central square steel is fixedly provided with several inner reinforcing vertical plates.

[0008] Preferably, the vertical steel plate is provided with edge protrusions on its upper and lower sides respectively.

[0009] Preferably, a transverse connecting auxiliary beam is provided on the upper part of the vertical steel plate.

[0010] Preferably, transverse concrete blocks are provided between the vertical steel plates. This application forms transverse concrete blocks by pouring concrete between the vertical steel plates and provides auxiliary transverse reinforcing bars and transverse connecting beams, thereby forming an integrated structure and ensuring the structural strength and stability of the connecting beam portion.

[0011] Preferably, auxiliary transverse reinforcement bars are provided inside the transverse concrete block.

[0012] This application can bring the following beneficial effects:

[0013] 1. This application achieves a better connection between reinforced concrete columns and steel structure beams by connecting the ring-shaped reinforcing bars that make up the reinforced concrete column with the steel structure beam. Since the structure is integrated, the connection will not cause potential problems such as the rebar breaking during use.

[0014] 2. This application sets an isolation angle steel between the central square steel and the ring steel. The isolation angle steel plays a role in ensuring the overall strength of the skeleton. While ensuring the strength of the skeleton, it can also prevent the ring steel from deforming and ensure the structural strength.

[0015] 3. This application forms a transverse concrete block by pouring concrete between vertical steel plates and setting auxiliary transverse reinforcing bars and transverse connecting beams, thereby forming an integrated structure and ensuring the structural strength and stability of the connecting beam part.
