[0027] The present invention will be further described below in conjunction with the embodiments.

[0028] like Figure 1-6 As shown, the utility model provides a rigid column foot structure of a multi-story steel structure frame column, comprising a concrete block 1, a column foot boot beam 2, a steel column 3 and a support assembly 4, wherein a reinforcement frame 11 adapted to the end structure of the steel column 3 is pre-embedded in the middle of the concrete block 1, and a plurality of anchor bolts 12 are pre-embedded on both sides of the reinforcement frame 11 and located on the concrete block 1, and the bottom end of the steel column 3 is embedded in the reinforcement frame 11, and the column foot boot beam 2 and the steel column 3 are both in an "H"-shaped structure;

[0029] Specifically, the reinforcement frame 11 can more evenly distribute the load transmitted by the steel column 3 to the concrete block 1, reducing local stress concentration. The cavity in the reinforcement frame 11 is aligned with the bottom end of the steel column 3 and inserted, effectively preventing the horizontal displacement of the steel column 3, simplifying the construction process, and reducing the need for welding or bolting.

[0030] Furthermore, the column foot boot beam 2 is arranged through the web of the steel column 3, a through slot 31 adapted to the structure of the column foot boot beam 2 is provided at the bottom of the web of the steel column 3, and a plurality of reinforcement holes 32 are provided on the web of the steel column 3 and above the column foot boot beam 2;

[0031] Specifically, the through groove 31 provides a precise guiding and positioning channel for the column base shoe beam 2, ensuring that the column base shoe beam 2 can be correctly inserted into and centered on the steel column 3. Through the through groove 31, the column base shoe beam 2 can be tightly matched with the web of the steel column 3 to form a stable cross structure, thereby improving the stability of the overall structure, helping to improve the torsional performance of the structure, and resisting lateral loads and wind forces, etc.

[0032] Furthermore, the width of the wing plate of the column foot shoe beam 2 is equal to the spacing between the two wing plates of the steel column 3, and the column foot shoe beam 2 and the steel column 3 are perpendicular to each other;

[0033] Specifically, the vertical layout of the column shoe beam 2 and the steel column 3 provides a stable cross structure, which increases the rigidity and stability of the entire structure. By ensuring that the sizes of the column shoe beam 2 and the steel column 3 match, the load can be transferred and dispersed more effectively, thereby improving the bearing capacity of the entire structure.

[0034] Furthermore, a support assembly 4 is installed between the upper wing plate of the column foot boot beam 2 and the web plate of the steel column 3, and the lower wing plate of the column foot boot beam 2 is fixed with screws to the anchor bolts 12, and the support assembly 4 includes a bottom plate 41 attached to the upper side of the upper wing plate of the column foot boot beam 2, and a side plate 42 fixed to one side of the bottom end of the bottom plate 41, a triangular plate 43 is fixedly connected between the bottom plate 41 and the side plate 42, and a limiting plate 44 is fixedly connected to two opposite sides of the side plate 42, wherein a plurality of first connection holes 45 are opened on the bottom plate 41, and a plurality of second connection holes 46 are opened on the side plate 42;

[0035] Specifically, the second connecting hole 46 is connected to the reinforcement hole 32 by bolts and nuts, so that the support assembly 4 and the steel column 3 can be connected into an integrated structure. The triangular plate 43 is fixedly connected to the bottom plate 41 and the side plate 42 to form a stable triangular structure, which helps to enhance the connection strength of the entire support assembly 4. When subjected to force, the triangular plate 43 helps to disperse the load to a wider area and reduce local stress concentration. The limit plate 44 helps to achieve the coordinated work between the support assembly 4 and the column base boot beam 2 and the steel column 3, thereby enhancing the integrity of the entire structure.

[0036] Furthermore, a plurality of first assembly holes 21 are provided on the upper wing plate of the column foot shoe beam 2 and on both sides of the steel column 3, and a plurality of second assembly holes 22 are provided on the lower wing plate of the column foot shoe beam 2 and on both sides of the steel column 3;

[0037] Specifically, the first connecting hole 45 is connected to the first assembly hole 21 by bolts and nuts, so that the column base shoe beam 2 and the support assembly 4 can be connected into an integrated structure. The anchor bolt 12 passes through the second assembly hole 22 and is threadedly connected to the nut to limit the position of the column base shoe beam 2.

[0038] Further, the second connection hole 46 corresponds to the reinforcement hole 32, the first connection hole 45 corresponds to the first assembly hole 21, and the second assembly hole 22 corresponds to the anchor bolt 12;

[0039] Specifically, various structural components can be accurately aligned to ensure the geometric accuracy and integrity of the structure, and the connection strength between structural components can be improved to ensure the stability and safety of the structure.

[0040] Furthermore, the width of the side plate 42 is equal to the distance between the two wing plates of the steel column 3, and the angle between the side plate 42 and the bottom plate 41 is 90°;

[0041] Specifically, the width of the side panel 42 is equal to the spacing between the wing panels of the steel column 3, which helps to optimize space utilization and ensure that there are no unnecessary gaps between structural components. When the side panel 42 is tightly matched with the wing panels of the steel column 3, the load can be more effectively transferred from the column foot boot beam 2 to the steel column 3, achieving uniform stress transfer, and the design of the side panel 42 helps to enhance the bending resistance of the entire support assembly 4, which is very important for bearing lateral loads and providing lateral support.

[0042] The rigid column foot structure of the multi-story steel structure frame column, when used, comprises the following steps:

[0043] Step 1: Prefabricate the concrete casting template, locate the positions of the reinforcement frame 11 and the anchor bolts 12, pour concrete into the casting template, and remove it after the concrete solidifies, so as to obtain a concrete block 1 with an exposed reinforcement frame 11 and anchor bolts 12;

[0044] Step 2: insert the column foot boot beam 2 into the through groove 31 of the steel column 3, and adjust the column foot boot beam 2 to the center position so that the column foot boot beam 2 and the steel column 3 together form a cross structure;

[0045] Step 3: Place the support assembly 4 in the angle between the upper wing plate of the column foot boot beam 2 and the web of the steel column 3, connect the second connection hole 46 with the reinforcement hole 32 through bolts and nuts, and connect the first connection hole 45 with the first assembly hole 21 through bolts and nuts, so as to reinforce the cross structure;

[0046] Step 4: Align the bottom end of the steel column 3 with the cavity in the reinforcement frame 11 and insert it to prevent the steel column 3 from horizontal displacement. During this process, the anchor bolt 12 passes through the second assembly hole 22 and is threadedly connected to the nut, which can limit the height of the column foot boot beam 2 and fully fix the steel column 3.
