[0002] A steel structure prefabricated building refers to a steel structure building in which steel structure components are prefabricated in a factory and assembled at a construction site. At the same time, steel structure prefabricated buildings are becoming more and more common in engineering applications. However, in the construction of steel structure buildings, it is usually necessary to connect the steel column bases. The existing connection method of the steel column base is to first embed the column base anchor bolts, then install the steel column, and finally carry out concrete pouring. However, since the existing building steel structures are usually relatively high, the required column base bending moment is large, and the existing steel column base structure cannot meet the requirements, thereby reducing the building safety. Content of the Utility Model

[0003] Therefore, the technical problem to be solved by the utility model is to overcome the defect in the prior art that the building safety is relatively low due to the large required column base bending moment.

[0005] A buried plate, which is arranged in the ground installation surface;

[0006] A pair of anchor plate assemblies, which are arranged at both ends of the buried plate and are connected to the bottom of the buried plate;

[0037] Embodiment

[0038] As Figures 1 to 4 shown, this embodiment provides a steel column base structure, including a buried plate 1, a pair of anchor plate assemblies 2, and anchor bars 3. The buried plate 1 is disposed in the ground mounting surface; the pair of anchor plate assemblies 2 are disposed at both ends of the buried plate 1 and are connected to the bottom of the buried plate 1; the anchor bars 3 are connected to the buried plate 1 and are located between the pair of anchor plate assemblies 2.

[0039] In the embodiment of the present utility model, first, an anchor member 21 is formed by welding steel plates, then the bottom plate 22 is welded to the bottom of the anchor member 21, and then the fasteners 23 are sequentially and evenly welded to the side wall of the anchor member 21 to form an anchor plate assembly. Then, the anchor plate assembly 2 is welded to the buried plate 1, and then the anchor bars 3 are welded to the buried plate 1 through the plug weld holes 12 to form a base structure.

[0040] In the construction of steel structure buildings, it is usually necessary to connect the steel column bases. The existing connection method of steel column bases is to first embed column base anchor bolts, then install the steel columns, and finally perform concrete pouring. However, due to the generally high height of existing building steel structures, the required base moment is large, and the existing steel column base structure cannot meet the requirements, thus resulting in relatively low building safety. In the embodiment of the present utility model, by providing the anchor plate assembly 2 and the anchor bars 3, the connection between the base and the concrete can be made more firm, and at the same time, the overall stress performance of the base is improved, thereby meeting the moment requirements for the base connection and enhancing the safety of the building structure.

[0041] Furthermore, as Figure 2As shown, the anchor plate assembly 2 includes an anchor 21, a base plate 22, and a fastener 23. The anchor 21 is connected to the embedded plate 1. The base plate 22 is disposed at the bottom of the anchor 21 and is welded to the anchor 21. The fastener 23 is disposed on the side wall end face of the anchor 21, and the fastener 23 is adapted to enhance the connection strength between the column base and the concrete. In the embodiment of the present utility model, by uniformly installing a plurality of the fasteners 23 on both sides of the side wall of the anchor 21, the connection strength between the anchor 21 and the concrete can be increased, thereby enhancing the overall mechanical properties of the column base.

[0042] Further, the anchor 21 has a C-shaped structure, and the C-shaped structure is formed by welding steel plates. That is, the anchor 21 has a groove-like structure. By pouring concrete into the groove of the anchor 21, the stability of the anchor 21 can be enhanced, thereby improving the overall performance of the column base structure.

[0043] Further, the fastener 13 is provided as a stud. In the embodiment of the present utility model, a plurality of studs are provided, and the distance between two studs is set to 200 mm. In addition, the length of the stud is set to 80 mm. Of course, this embodiment only gives an example of the length of the stud and the distance between the studs, and does not limit it. Those skilled in the art can change the length of the stud and the distance between the studs according to the actual situation, as long as the same technical effect can be achieved.

[0044] Further, a plurality of first through holes 24 are uniformly provided on the side wall of the anchor 21. The first through holes 24 are spaced apart from the fasteners 23. The first through holes 24 are adapted to allow air to pass through to ensure the density of the concrete. In the embodiment of the present utility model, the first through holes 24 are circular, and the diameter of the first through holes 24 is set to 16 mm. Of course, the first through holes 24 can also be set as square holes. This embodiment does not limit the diameter size and shape of the first through holes 24. Those skilled in the art can change the diameter size and shape of the first through holes 24 according to the actual situation, as long as the same technical effect can be achieved.

[0045] Further, as Figure 4 shown, a second through hole 11 is provided in the middle of the embedded plate 1. The second through hole 11 is adapted to allow air to pass through to ensure the density of the concrete. The second through hole 11 is circular, and the diameter ranges from 99 mm to 101 mm. In the embodiment of the present utility model, the diameter size of the second through hole 11 is set to 100 mm. Of course, this embodiment does not limit the diameter size of the second through hole 11. Those skilled in the art can change the diameter size of the second through hole 11 according to the actual situation, as long as the same technical effect can be achieved.

[0046] Further, a plurality of plug weld holes 12 are provided on the embedded plate 1, and the plug weld holes 12 are adapted for the anchor bars 3 to be inserted therein and welded to the anchor bars 3. The number of the plug weld holes 12 corresponds to the number of the anchor bars 3. In the embodiment of the present invention, six plug weld holes 12 are provided, and three are correspondingly provided at each end of the embedded plate 1. Of course, the number of the plug weld holes 12 in this embodiment is not limited, and those skilled in the art can change the number of the plug weld holes 12 according to the actual situation as long as the same technical effects can be achieved.

[0047] Further, as Figure 3 shown, the anchor bars 3 are bent at 90° and extend along the short side direction of the embedded plate 1. The bent anchor bars 3 are adapted to enhance the bending resistance of the column base. By pouring concrete on the bent anchor bars 3, the bending resistance performance of the column base structure can be improved, thereby enhancing the stability of the building. In the embodiment of the present invention, six anchor bars 3 are provided. In addition, the diameter of the anchor bars 3 is 32 mm and the length is 1667 mm. Of course, the dimensions of the anchor bars 3 in this embodiment are illustrated and not limited thereto. Those skilled in the art can change the dimensions of the anchor bars 3 according to the actual situation as long as the same technical effects can be achieved.

[0048] The specific working process of the steel column base structure provided by the present invention is as follows:

[0049] First, the bottom plate 22 and the fasteners 23 are respectively welded to the anchor member 21 to form the anchor plate assembly 2, then the anchor plate assembly 2 is welded to the embedded plate 1, then the anchor bars 3 are welded to the embedded plate 1 through the plug weld holes 12, then concrete is poured into the column base structure, and then the column base structure is connected to the building main body to complete the working process of the column base structure.

For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description.
