Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to spliced ​​steel columns for prefabricated frame structures. Background Technology

[0002] In the field of building construction, steel columns, as a crucial component of load-bearing and supporting structures, are of paramount importance in terms of stability and connection reliability. Traditionally, steel column connections in buildings are typically achieved through welding or direct bolting. While welding offers high strength, it is complex to construct, requires specific on-site working conditions, and the thermal stress generated during welding can degrade material properties, affecting the overall structural durability. Direct bolting, on the other hand, lacks sufficient guiding and positioning mechanisms, making precise alignment difficult during installation, increasing installation difficulty and time costs. Furthermore, the connection area between the outer wall of the steel column and the flange often lacks adequate reinforcement, making these areas prone to deformation under stress, further impacting the structure's load-bearing capacity and safety.

[0003] Therefore, spliced ​​steel columns for prefabricated frame structures are proposed. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the present utility model.

[0032] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Reference Figures 1-4 This utility model provides splicing steel columns for prefabricated frame structures, including an upper steel column 1 and a lower steel column 2. A guide component is installed on the inner wall of the lower steel column 2, and the guide component is engaged with the inner cavity of the upper steel column 1.

[0034] The upper wing plate 3 is fixed to the bottom of the outer wall of the upper steel column 1, and the lower wing plate 4 is fixed to the top of the outer wall of the lower steel column 2. The upper wing plate 3 and the lower wing plate 4 are detachably connected by bolt assembly.

[0035] Reinforcing rib assemblies are installed between the upper flange 3 and the outer wall of the upper steel column 1, and between the lower flange 4 and the outer wall of the lower steel column 2.

[0036] Two symmetrically arranged positioning mechanisms are installed on the upper wing plate 3. Two symmetrically arranged first positioning through holes 5 are opened on the upper wing plate 3, and two symmetrically arranged second positioning through holes 6 are opened on the lower wing plate 4. The positioning mechanism passes through the first positioning through hole 5 and is inserted into the second positioning through hole 6.

[0037] With this configuration, the present invention achieves initial guidance of the upper steel column 1 and lower steel column 2 during installation by installing a guide component on the inner wall of the lower steel column 2 and engaging the guide component with the inner cavity of the upper steel column 1. By connecting the two positioning mechanisms to the two second positioning through holes 6 respectively, the upper steel column 1 and lower steel column 2 can be precisely positioned again during installation, thereby reducing installation difficulty and time cost, and improving installation efficiency and accuracy.

[0038] In this utility model, the upper wing plate 3 and the lower wing plate 4 are detachably connected by a bolt assembly. The reinforcing rib assembly significantly enhances the connection strength between the upper steel column 1 and the lower steel column 2, effectively preventing deformation under stress, improving the overall stability and load-bearing capacity of the structure, and enhancing the stability and reliability of the connection.

[0039] The plan has been further optimized, and the positioning institutions include:

[0040] Sleeve 7 is installed on the top surface of the upper wing plate 3;

[0041] Spring 8, the bottom of spring 8 is fixed to the inner bottom wall of sleeve 7, and the top of spring 8 extends out of sleeve 7;

[0042] Top plate 9, one side of the bottom surface of top plate 9 is fixedly connected to the top of spring 8;

[0043] Positioning rod 10 is fixedly installed at the bottom of top plate 9 via connecting rod 11. The first positioning through hole 5 and the second positioning through hole 6 are both inserted into the positioning rod 10.

[0044] Among them, the two sleeves 7 are symmetrically installed on the top surface of the upper wing plate 3;

[0045] By pulling up the top plate 9, the positioning rod 10 is raised. After adjusting the alignment of the first positioning through hole 5 and the second positioning through hole 6, the top plate 9 is released. Under the action of the spring 8, the positioning rod 10 descends and inserts into the first positioning through hole 5 and the second positioning through hole 6. The two positioning mechanisms achieve precise positioning of the upper wing plate 3 and the lower wing plate 4. The operation is simple and convenient.

[0046] The scheme is further optimized. The guide component includes a guide inner cylinder 12, which is fixedly installed on the top of the inner wall of the lower steel column 2, and the top of the guide inner cylinder 12 extends out of the lower steel column 2.

[0047] A limiting ring 13 is installed at the bottom of the inner wall of the upper steel column 1. The top of the guide inner cylinder 12 extends into the inner cavity of the upper steel column 1, and the top of the guide inner cylinder 12 abuts against the limiting ring 13. During the installation process, when the upper steel column 1 begins to descend, its inner cavity will contact the guide inner cylinder 12 and descend along its surface. The guiding effect of the guide inner cylinder 12 ensures that the upper steel column 1 can descend smoothly along the predetermined path until the limiting ring 13 abuts against the top of the guide inner cylinder 12, thus achieving the initial alignment of the upper steel column 1 and the lower steel column 2.

[0048] The scheme is further optimized. The bolt assembly includes several screws 14, several first threaded holes are opened on the upper wing plate 3, and several second threaded holes are opened on the lower wing plate 4. The screws 14, the first threaded holes and the second threaded holes are set in a one-to-one correspondence.

[0049] The screw 14 passes through the first threaded hole and the second threaded hole. Both the first threaded hole and the second threaded hole are threadedly connected to the screw 14. Two nuts 15 are threadedly connected to the screw 14. The two nuts 15 abut against the upper wing plate 3 and the lower wing plate 4 respectively.

[0050] During installation, the screw 14 is first passed through the first threaded hole and the second threaded hole, and then the nuts 15 are tightened on both sides of the screw 14. As the nuts 15 are tightened, the gap between the upper wing plate 3 and the lower wing plate 4 will gradually decrease until the predetermined fastening force is reached, thereby achieving a stable connection between the upper wing plate 3 and the lower wing plate 4.

[0051] Further optimization of the scheme: the reinforcing rib assembly includes several reinforcing rib bodies 16. Several reinforcing rib bodies 16 are installed between the upper wing plate 3 and the outer wall of the upper steel column 1, and between the lower wing plate 4 and the outer wall of the lower steel column 2.

[0052] The reinforcing rib body 16, the upper flange 3 and the outer wall of the upper steel column 1, and the reinforcing rib body 16, the lower flange 4 and the outer wall of the lower steel column 2 are firmly connected together to form an integral structure. This not only improves the overall stability of the structure, but also enhances its load-bearing capacity, enabling the spliced ​​steel columns of the prefabricated frame structure to better withstand various loads.

[0053] The scheme was further optimized by increasing the number of reinforcing rib bodies 16 to four, with the four reinforcing rib bodies 16 arranged symmetrically.

[0054] The design is further optimized so that the top hole diameter of the second positioning through hole 6 is larger than the bottom hole diameter of the second positioning through hole 6, which facilitates the insertion of the positioning rod 10.
