[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0021] In order to make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0022] Refer to Figures 1-4The utility model discloses a pre-embedded positioning bolt device for an independent foundation steel column foot under a steel structure column, comprising a top plate 1, a plurality of bolts 3 being provided on the top plate 1, a plurality of connecting plates 6 being fixedly connected between two adjacent bolts 3, the connecting plates 6 being provided below the top plate 1, a supporting assembly being fixedly connected below the top plate 1 through a plurality of U-shaped frames 5, and the end of the supporting assembly away from the top plate 1 being fixedly connected to the foundation short column.

[0023] The connecting plate 6 is made of threaded steel.

[0024] The utility model fixes the support assembly to the foundation short column, and the support assembly is fixedly connected to the top plate 1 through a plurality of U-shaped frames 5. The positions of a plurality of bolts 3 are positioned by the top plate 1, and two adjacent bolts 3 are limited by a plurality of connecting plates 6, so that the position of the bolt 3 will not shake during the pouring of concrete, thereby effectively improving the positioning accuracy of the bolt 3.

[0025] In a further optimized solution, a through hole 4 is provided on the top plate 1, which effectively reduces the weight of the top plate 1.

[0026] In a further optimized solution, a plurality of bolts 3 are arranged around the through hole 4. The positions of the plurality of bolts 3 can be set according to design requirements.

[0027] To further optimize the solution, the two ends of the bolt 3 extending out of the top plate 1 are respectively threadedly connected with nuts 9. The nuts 9 provided on both sides of the top plate 1 not only make the length of the bolt 3 extending out of the top surface of the top plate 1 adjustable, but also enable the bolt 3 to be stably placed on the top plate 1.

[0028] As a further optimization solution, the U-shaped frame 5 includes a horizontal plate, both ends of which are fixedly connected to vertical plates, the ends of the two vertical plates away from the horizontal plate are fixedly connected to the top plate 1, and the ends of the horizontal plate away from the vertical plate are fixedly connected to the support assembly.

[0029] According to a further optimized solution, the support assembly includes an upper frame 2, the top surface of the upper frame 2 is fixedly connected to the horizontal plate, the corners of the bottom surface of the upper frame 2 are respectively fixedly connected to support rods 7, and the end of the support rods 7 away from the upper frame 2 is fixedly connected to the lower frame 8.

[0030] According to a further optimized solution, the outer wall of the lower frame 8 is fixedly connected to the foundation short column.

[0031] To further optimize the solution, angle steel is used for the horizontal plates, vertical plates, upper frame 2, support rods 7, and lower frame 8. By using angle steel, the horizontal plates, vertical plates, upper frame 2, connecting plates 6, support rods 7, and lower frame 8 are less likely to deform and shake during concrete pouring, effectively ensuring the accurate positioning of bolts 3.

[0032] Working process: Positioning holes for bolts 3 are drilled on the top plate 1 according to the design requirements. The bolts 3 are installed into the positioning holes through nuts 9, and the length of the bolts 3 protruding from the top surface of the top plate 1 is adjusted by the nuts 9. Then, a plurality of connecting plates 6 arranged in parallel are welded between two adjacent bolts 3 located below the top plate 1. Synchronously, the upper frame 2 and the lower frame 8 are fabricated according to the position of the foundation short column. The upper frame 2 and the lower frame 8 have the same structure. Then, the support rods 7 are welded between the upper frame 2 and the lower frame 8. Then, a plurality of cross plates are welded on the upper frame 2. Then, vertical plates are welded at both ends of the cross plates, and then the vertical plates are welded to the bottom surface of the top plate 1. Finally, the outer wall of the lower frame 8 is welded to the foundation short column.
