[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0023] See also Figures 1 to 3The utility model embodiment provides a steel structure wall column base quick connection structure, the steel structure wall column base quick connection structure comprises: a foundation embedded plate 1 embedded in the foundation and a wall column 3 installed on the foundation embedded plate 1.

[0024] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 and Figure 3 The foundation embedded plate 1 is fixedly embedded with an insertion column 2, and the insertion column 2 is provided with a plurality of annularly distributed and vertically arranged insertion grooves 2a, and the insertion column 2 at the bottom of each of the insertion grooves 2a is provided with an arc groove 2b connected with the insertion groove 2a, and the insertion groove 2a and the arc groove 2b form an L-shaped cavity structure, and the bottom of the foundation embedded plate 1 is fixedly embedded with a plurality of evenly distributed U-shaped steel bars 8, and the bottom of the wall column 3 is provided with an insertion cavity 3a, and the inner wall of the insertion cavity 3a is fixedly embedded with a plurality of annularly distributed limit sliders 4, and the limit slider 4 in the wall column 3 is inserted into the insertion groove 2a formed by the insertion column 2 and rotates around the arc groove 2b to the inner groove side of the arc groove 2b.

[0025] It should be noted that: the foundation embedded plate 1 is embedded in the installation area, and the U-shaped steel bar 8 is provided to improve the connection strength with the embedded concrete. Subsequently, the wall column 3 is inserted into the insertion column 2, and the limit slider 4 in the wall column 3 is kept corresponding to the insertion groove 2a at the top of the insertion column 2. Then, the wall column 3 slides down along the insertion column 2 to the lowest point, and then rotates around the arc groove 2b to the arc groove 2b, thereby completing the connection between the wall column 3 and the insertion column 2 on the foundation embedded plate 1, making it more convenient to install and fix, and avoiding wasting a lot of time and affecting the progress of the construction period during construction;

[0026] The insertion cavity 3 a in the wall column 3 is sleeved with a rubber sleeve, which improves the stability of the wall column 3 when inserted in the insertion column 2 .

[0027] In the embodiments of the present invention, please refer to Figure 2 and Figure 3 A plurality of annularly distributed threaded columns 5 are fixedly embedded on the foundation embedded plate 1, and a chassis 6 is fixedly embedded at the bottom of the wall column 3, and a plurality of annularly distributed arc-shaped sliding cavities 6a are opened on the chassis 6, and the arc-shaped sliding cavities 6a opened on the chassis 6 are inserted into the threaded columns 5 and fixedly connected by tightening nuts 7.

[0028] It should be noted that: when the wall column 3 slides down along the insertion column 2, the threaded column 5 is inserted into the arc-shaped sliding cavity 6a on the chassis 6. When the wall column 3 is subsequently rotated, the arc-shaped sliding cavity 6a on the chassis 6 slides along the threaded column 5, and then it is tightened by the fastening nut 7.
