Description

Technical Field

[0001] This utility model relates to the field of irregular column steel frame technology, and in particular to an irregular column steel frame structure. Background Technology

[0002] Irregular column steel frame structure is a special steel structure system. Its core is to replace the conventional cross-section steel columns such as rectangular or I-shaped steel columns in the traditional steel frame with irregular steel columns with asymmetrical cross-sections. These irregular steel columns are then assembled with steel beams through welding, bolting and other methods to form an integral load-bearing frame.

[0003] For example, a type of irregular-shaped column steel frame structure with authorization announcement number "CN219863667U" uses a connecting mechanism to facilitate the assembly and disassembly of the lower and upper columns, reducing installation difficulty. It also allows for the disassembly of the irregular-shaped columns, minimizing space occupation. The core value of irregular-shaped column steel frames is reducing protruding columns indoors; however, traditional irregular-shaped column steel frame structures often leave small protrusions at the junction of the wall and steel beams due to loose connections between the steel beams and columns. Summary of the Invention

[0004] This utility model aims to solve the problems existing in the prior art by providing an irregularly shaped column steel frame structure, thereby reducing small protrusions at the junction of the wall and the steel beam.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This irregular column steel frame structure includes an irregular column and a first threaded hole. The inner wall of the irregular column is machined with the first threaded hole. The inner end of the irregular column is in contact with the vertical plate. The upper and lower sides of the inner wall of the vertical plate are machined with second threaded holes. The first threaded hole and the second threaded hole are both threadedly connected to the first bolt. The inner side of the vertical plate is provided with an irregular column steel frame structure.

[0006] To further improve the design, the irregular column steel frame structure includes a horizontal plate, the middle of which is fixedly connected to a first support plate, and a second support plate is fixedly connected to both sides of the horizontal plate. The inner wall of the second support plate is provided with a third threaded hole.

[0007] To further improve the design, a fourth threaded hole is machined in the middle of the inner wall of the vertical plate.

[0008] To further improve the design, the inner walls of both the third and fourth threaded holes are threadedly connected to the second bolt.

[0009] Further improvements were made, with both ends of the first support plate flush with the outer wall of the horizontal plate.

[0010] The beneficial effects of this utility model are as follows: Through the cooperation of the irregularly shaped column steel frame structure and the vertical plates, the horizontal plates are arranged horizontally, directly bearing the floor load on both the upper and lower sides. Second support plates are fixed on both sides, while the first support plate in the middle of the horizontal plate is perpendicular to the horizontal plate, enhancing its bending resistance and preventing it from protruding into the room. Furthermore, the thickness of the second support plate matches the vertical plate, and after installation, it is flush with the surface of the vertical plate without any additional protrusions. The irregularly shaped column transfers the vertical load to the irregularly shaped column steel frame structure through the vertical plates, and the floor load borne by the horizontal plates is transferred back to the irregularly shaped column through the second support plates and the vertical plates, forming a complete closed-loop force distribution. Throughout the process, all components are precisely aligned through threaded holes and tightly connected with bolts, achieving the connection between the "irregularly shaped column-vertical plate-steel frame," thereby reducing small protrusions at the junction of the wall and the steel beam.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings:

[0018] See attached document Figure 1-5In this embodiment, an irregularly shaped column steel frame structure includes an irregularly shaped column 1 and a first threaded hole 2. The inner wall of the irregularly shaped column 1 is machined with the first threaded hole 2. The inner end of the irregularly shaped column 1 is in contact with the vertical plate 3. The upper and lower sides of the inner wall of the vertical plate 3 are machined with second threaded holes 4. The first threaded hole 2 and the second threaded hole 4 are both threadedly connected to the first bolt 5. The first bolt 5 fixes the irregularly shaped column 1 and the vertical plate 3 together. An irregularly shaped column steel frame structure 6 is provided on the inner side of the vertical plate 3. A fourth threaded hole 8 is machined in the middle of the inner wall of the vertical plate 3. The inner walls of the third threaded hole 604 and the fourth threaded hole 8 are both threadedly connected to the second bolt 7. The second bolt 7 fixes the irregularly shaped column steel frame structure 6 and the vertical plate 3 together. Both ends of the first support plate 602 are flush with the outer wall of the horizontal plate 601. The width of the first support plate 602 is the same as that of the horizontal plate 601.

[0019] See attached document Figure 1-4 The irregular column steel frame structure 6 includes a horizontal plate 601, the middle of which is fixedly connected to the first support plate 602, and the two sides of the horizontal plate 601 are fixedly connected to the second support plate 603. The inner wall of the second support plate 603 is provided with a third threaded hole 604.

[0020] Working principle:

[0021] When using irregularly shaped column steel frame structures:

[0022] Fixing irregularly shaped columns to vertical plates;

[0023] The irregular column 1 is vertically arranged at the edge of the building wall, such as the corner. The first threaded hole 2 on its inner wall is aligned with the second threaded holes 4 on the upper and lower sides of the vertical plate 3. The first bolt 5 is screwed into the aligned threaded hole. The tightening force of the first bolt 5 makes the vertical plate 3 fit tightly against the inner end of the irregular column 1, forming a stable vertical bearing foundation. The surface of the vertical plate 3 is flush with the irregular column 1 to avoid step protrusions at the joint.

[0024] Installation of irregularly shaped column steel frame structure 6:

[0025] In this structure, the horizontal plate 601 is arranged horizontally, and its upper and lower sides can directly bear the floor load. The second support plate 603 fixed on both sides corresponds precisely to the fourth threaded hole 8 in the middle of the vertical plate 3. During installation, the third threaded hole 604 on the inner wall of the second support plate 603 is aligned with the fourth threaded hole 8 in the vertical plate 3, and then the second bolt 7 is inserted and tightened to make the irregular column steel frame structure 6 and the vertical plate 3 tightly connected. At the same time, the first support plate 602 in the middle of the horizontal plate 601 is perpendicular to the horizontal plate 601, which not only enhances the bending resistance of the horizontal plate 601, but also prevents it from protruding into the room. In addition, the thickness of the second support plate 603 is adapted to the vertical plate 3, and after installation, it is flush with the surface of the vertical plate 3 without any extra protrusion.

[0026] After the overall assembly is completed, the irregular column 1 transfers the vertical load to the irregular column steel frame structure 6 through the vertical plate 3. The floor load borne by the horizontal plate 601 is transferred to the irregular column 1 in the opposite direction through the second support plate 603 and the vertical plate 3, forming a complete closed loop of force. Throughout the process, the components are precisely aligned through threaded holes and tightly connected with bolts to achieve the connection of "irregular column-vertical plate-steel frame", thereby reducing the small protrusions at the junction of the wall and the steel beam.

[0027] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
