[0025] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The utility model embodiment is an adjustable steel structure base embedded part, which includes a bottom plate 1 and two connecting plates 6. The bottom of the bottom plate 1 is fixedly connected with a first support column 2 of a hollow structure, the inside of the first support column 2 is slidably connected with a second support column 3, the top of the second support column 3 is fixedly connected with a top plate 4, the top plate 4 is installed with a mounting plate 5, and the two connecting plates 6 are symmetrically fixedly connected to the top of the mounting plate 5; a pre-positioning component for fixing the second support column 3 is arranged inside the first support column 2, and the pre-positioning component includes a plurality of positioning holes 9, a first screw rod 7 and a first nut 8 that are equidistantly and symmetrically opened inside the first support column 2, and the first screw rod 7 is provided with an outer screw One end of the thread penetrates the interior of the first support column 2 and the second support column 3 and extends to the outside of the first support column 2, and the first nut 8 is threadedly connected to the end of the first support column 2 with an external thread; the first support column 2 is provided with a circulation port 10 around the bottom, specifically, the second support column 3 is moved according to the depth of the foundation pit or the adjustment of the steel structure building, and the overall length of the first support column 2 and the second support column 3 can be adjusted by moving the second support column 3, and the first screw rod 7 is inserted into the interior of the second support column 3 after being plugged into the positioning hole 9 at the corresponding position, and the first nut 8 is tightened on the outside of the first screw rod 7 to position the second support column 3. After the embedded part is placed in the foundation pit, concrete is filled into the foundation pit, and at the same time, the concrete flows into the interior of the first support column 2 through the circulation port 10. When the embedded part is fixed to the ground, the concrete flowing into the interior of the first support column 2 can support and fix the second support column 3 to ensure that the second support column 3 is tightly connected to the first support column 2, so that the embedded part has sufficient bearing capacity and stability, and the quality of the steel structure building is guaranteed.

[0026] The top plate 4 and the mounting plate 5 are fixedly connected by a connecting assembly, and the connecting assembly includes a plurality of second screws 11 equidistantly and symmetrically fixedly connected to the inside of the top plate 4 and a plurality of second nuts 12 attached to the top of the mounting plate 5. The tops of the plurality of second screws 11 all penetrate the inside of the mounting plate 5 and are threadedly connected to the second nuts 12. Specifically, the mounting plate 5 is fixed to the top plate 4 by the cooperation of the second screws 11 and the second nuts 12. The connection is stable and the movable connection is convenient for disassembly of the mounting plate 5, so that different types of connecting plates 6 can be replaced to connect to the bases of different steel structure buildings, and it is flexible to use.

[0027] The bottoms of the multiple second screw rods 11 all extend to a position flush with the bottom of the first support column 2 and are all arranged in an L-shaped structure. Specifically, when the second screw rod 11 with an L-shaped structure at the bottom extends into the interior of the foundation pit, the contact area with the concrete can be increased, thereby easily connecting and fixing the second screw rod 11 inside the foundation pit, increasing the stability of the connection between the top plate 4 and the foundation pit, thereby helping to improve the stability of the building.

[0028] There are two pre-positioning components, which are vertically arranged up and down. The two pre-positioning components can increase the stability of the connection between the second support column 3 and the first support column 2, thereby ensuring the stability of the building on the mounting plate 5.

[0029] A limiting plate with an annular structure is fixedly connected inside the first support column 2 and near the top of the flow port 10. When the second support column 3 moves up and down inside the first support column 2, the limiting plate can prevent the second support column 3 from moving to the bottom of the first support column 2 to block the flow port 10, so as to ensure the normal flow of concrete.

[0030] The first screw rod 7 is located between two adjacent second screw rods 11 , so that the second screw rod 11 can be prevented from interfering with the installation of the first screw rod 7 .

[0031] Working principle: Move the second support column 3 according to the depth of the foundation pit or the adjustment of the steel structure building. The overall length of the first support column 2 and the second support column 3 can be adjusted by moving the second support column 3. Insert the first screw 7 into the positioning hole 9 at the corresponding position and insert it into the inside of the second support column 3. Tighten the first nut 8 on the outside of the first screw 7 to position the second support column 3. After the embedded part is placed in the foundation pit, fill the foundation pit with concrete, and at the same time, the concrete flows into the first support column 2 through the flow port 10. When the embedded part is fixed to the ground, the concrete flowing into the first support column 2 can support and fix the second support column 3 to ensure that the second support column 3 is tightly connected to the first support column 2, so that the embedded part has sufficient bearing capacity and stability, ensuring the quality of the steel structure building;

[0032] When the embedded parts are poured, the second screw 1 with an L-shaped structure at the bottom can increase the contact area with the concrete, thereby easily connecting and fixing the second screw 11 inside the foundation pit, increasing the stability of the connection between the top plate 4 and the foundation pit, thereby further improving the stability of the steel structure building.

[0033] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
