[0002] In the building structure system, reinforced concrete structure is currently the most commonly used structural form. In order to avoid the frame column being too large and affecting the effective use area in the design, steel-concrete columns are often used. This raises the problem of how to conveniently connect the beam reinforcement at the node and the steel section in the column. The commonly used methods are to transfer through a steel bar connector or by welding the steel bars to the steel corbels set on the steel columns.

This structure solves the problem of poor welding conditions on site that the welding quality cannot be guaranteed by connecting the second row of steel bars of the steel plate strip concrete beam.

[0027] This embodiment provides a connection structure between a concrete beam and a steel reinforced concrete column, including an embedded part 1 provided on the steel reinforced concrete column a and a bracket structure 2 installed on the embedded part 1.

[0028] In this embodiment, the steel reinforced concrete column a is a circular concrete column or a square concrete column.

[0029] In this embodiment, the embedded part 1 includes a base body 101, a side groove 102 provided on the base body 101, and a plurality of first connection holes 103 provided on the side groove 102.

Such an installation method can, on the basis of ensuring the strength of the base body 101, also select the installation position of the base body 101 according to the installation position of the concrete beam, so as to determine the fixing position of the bracket structure. That is, after installing the threaded steel bars in all directions of the steel reinforced concrete column, then determine the position where the bracket structure needs to be installed according to the on-site situation, and the redundant threaded steel bars can be directly cut off to ensure the flatness of the surface of the steel reinforced concrete column.

[0035] The two side plates 206 adopted in this embodiment can enclose the gap between the upper and lower connecting plates and the web raised by the block body to form a sealed cavity, and a filler such as concrete slurry is injected into the sealed cavity through the pouring hole, so as to reinforce the connection strength between the seat body and the web and between the web and the connecting plate.

[0036] As a further preference of this embodiment, both the upper connecting plate 203 and the lower connecting plate 204 protrude from the end of the web 201 and are welded to the steel reinforced concrete column a to form a first welding point b.

[0037] As a further preference of this embodiment, the end of the side plate 206 away from the block body is welded to the steel reinforced concrete column a to form a second welding point c.

[0038] The construction process of the connection structure provided by this embodiment is as follows: S1. Embed the threaded steel bars in a manner perpendicular to the surface of the steel reinforced concrete column during the pouring of the steel reinforced concrete column; S2. Simulate and position the bracket structure, and then install the seat body and the bracket structure in sequence; S3. Determine the welding position, and clean the slag, oil stain, dust, and floating rust at this position before welding to ensure the welding quality; S4. Inject the filler into the pouring hole and wait for the filler to solidify to complete the installation of the connection structure; S5. Cut off the corresponding threaded steel bars on the surface of the concrete column and polish them to ensure the surface is flat.

[0039] The connection structure provided by this embodiment, compared with the existing device, only needs to embed the threaded steel bars during the pouring stage, the number of components to be embedded is small, and the construction is relatively simple; when installing the bracket structure, the installation steps are simple, and the number of welding points is greatly reduced, further simplifying the construction process and avoiding the problem that the strength of the device is affected due to the difficult control of welding quality. It has the advantages of strong practicability and simple process.
