The device can use the automatic guiding structure under gravity for precise positioning, thereby improving the efficiency of this type of connection, improving the overall assembly efficiency, and reducing the difficulty of installation quality control.

[0004] Although the above patent improves the efficiency of connecting steel columns and foundations, improves the overall assembly efficiency, and reduces the difficulty of installation quality control, in actual use, the guiding method of the cross connecting plate with an arc angle can improve the assembly efficiency of steel columns and foundation paper parts, but the cross groove on the steel column positioning plate needs to be adjusted when docking with the cross piece on the foundation, and the assembly efficiency can be further improved. Therefore, in response to the above problems, we propose a new type of introduction device for assembled steel column foundations. Utility Model Content

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides an introduction device for an assembled steel column foundation, including a steel column mechanism 1, a foundation mechanism 2 is arranged below the steel column mechanism 1, a plurality of connection mechanisms 3 are arranged inside the foundation mechanism 2, the steel column mechanism 1 includes a positioning plate 102, a guide column 105 is fixedly connected to the bottom center of the positioning plate 102, a guide head 106 is fixedly connected to the bottom of the guide column 105, the foundation mechanism 2 includes a concrete foundation 201, a guide groove 202 is opened at the top center of the concrete foundation 201, a contraction groove 203 is opened at the inner bottom of the guide groove 202, the guide head 106 and the guide column 105 are plug-in connected to the guide groove 202, the guide head 106 and the contraction groove 203 are plug-in connected, the guide column 105 is square in cross section and the upper and lower ends are of the same size, the guide head 106 is in cross section and is in a contracted state as a whole, the top size of the guide head 106 is consistent with the size of the guide column 105 and the bottom The end size is smaller than the top size, the guide groove 202 and the guide column 105 are matched in size, the contraction groove 203 and the guide head 106 are matched in size, and a plurality of mounting holes 103 are equidistantly provided at the top of the positioning plate 102 near the edge, and a steel column body 101 is fixedly connected at the top center of the positioning plate 102, and a plurality of reinforcing steel plates 104 whose positions are staggered with the mounting holes 103 are fixedly connected between the outer surface of the steel column body 101 and the top of the positioning plate 102, and the plurality of connecting mechanisms 3 all include steel bars 301, and the plurality of steel bars 301 are all pre-buried in the interior of the concrete foundation 201 and the top ends extend upward, and the outer surfaces of the steel bars 301 are symmetrically threaded with the first bolt 302 and the second bolt 305, and the outer surfaces of the plurality of steel bars 301 are respectively slidably fitted with the inner surface walls of the plurality of mounting holes 103, and the first bolt 302 is located below the positioning plate 102, and the second bolt 305 is located above the positioning plate 102.

[0024] The effect achieved by the entire embodiment 1 is that when assembling the steel column and the foundation, the first bolt 302 on the surface of the steel bar 301 is rotated as needed to adjust it to a suitable height, and then the steel column body 101 is lifted by a lifting device and moved to the top of the concrete foundation 201 and slowly lowered. Since the bottom of the guide head 106 is smaller than the guide groove 202 at the top of the concrete foundation 201, as the steel column body 101 falls, the guide head 106 can easily enter the guide groove 202, reducing the difficulty of alignment and insertion. When the guide head 106 continues to fall, the gradually thickened part can gradually contact the inner wall of the guide groove 202, providing a guide column 105 The guide and self-adjusting functions are certain. Even if there is a slight deviation during the initial insertion, as the insertion depth of the guide head 106 increases, the thicker part will be restricted and guided by the wall of the guide groove 202, thereby automatically correcting the deviation, so that the square guide column 105 can be smoothly inserted into the guide groove 202 at the top of the concrete foundation 201. At this time, the mounting hole 103 on the surface of the positioning plate 102 will just be penetrated by the corresponding steel bar 301. At this time, tightening the second bolt 305 can complete the assembly of the steel column and the foundation. No excessive adjustment is required, the operation is convenient, and the assembly efficiency is effectively improved. The reinforcing steel plate 104 is provided to improve the connection strength between the steel column body 101 and the positioning plate 102.

[0025] Embodiment 2, as Figure 1-Figure 4 As shown, the outer surface of the steel bar 301 is provided with a first anti-skid plate 303 and a second anti-skid plate 304 , the first anti-skid plate 303 is located between the first bolt 302 and the outer surface of the positioning plate 102 , and the second anti-skid plate 304 is located between the second bolt 305 and the outer surface of the positioning plate 102 .

[0026] The effect achieved by the entire embodiment 2 is that the first anti-skid plate 303 is set between the first bolt 302 and the positioning plate 102 to increase the friction between the two, and the second anti-skid plate 304 is set between the second bolt 305 and the positioning plate 102 to increase the friction between the two. Therefore, when the first bolt 302 and the second bolt 305 are tightened, it is difficult for them to rotate, thereby ensuring the fixing effect of the positioning plate 102 and improving the firmness of the steel column and foundation assembly.

[0027] Working principle: When assembling the steel column and the foundation, turn the first bolt 302 on the surface of the steel bar 301 as needed and adjust it to a suitable height. Then use the lifting equipment to lift the steel column body 101 and move it above the concrete foundation 201 and slowly lower it. As the steel column body 101 falls, the guide head 106 can easily enter the guide groove 202, reducing the difficulty of alignment and insertion. As the guide head 106 continues to fall, the gradually thickened part can gradually contact the inner wall of the guide groove 202, providing a certain amount of guidance and self-adjustment for the guide column 105. Even if there is a slight deviation during the initial insertion, as the insertion depth of the guide head 106 increases, the thicker part will be restricted and guided by the wall of the guide groove 202, thereby automatically correcting the deviation, so that the square guide The column 105 can be smoothly inserted into the guide groove 202 at the top of the concrete foundation 201. At this time, the mounting hole 103 on the surface of the positioning plate 102 will be just penetrated by the corresponding steel bar 301. At this time, tightening the second bolt 305 can complete the assembly of the steel column and the foundation. No excessive adjustment is required, the operation is convenient, and the assembly efficiency is effectively improved. In addition, a first anti-skid plate 303 is provided between the first bolt 302 and the positioning plate 102 to increase the friction between the two. A second anti-skid plate 304 is provided between the second bolt 305 and the positioning plate 102 to increase the friction between the two. Therefore, when the first bolt 302 and the second bolt 305 are tightened, it is difficult for them to rotate, thereby ensuring the fixing effect of the positioning plate 102 and improving the firmness of the assembly of the steel column and the foundation.
