Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of assembling steel structure columns, in particular to a steel structure column that can be freely spliced and assembled. Background Art
[0002] An assembled steel structure column is a building component made of high-strength steel and is commonly used in frame structures, support systems, and bridge construction. They usually have the characteristics of standardization and modularity, and can be assembled and installed quickly and efficiently. The advantages of assembled steel structure columns lie in their excellent load-bearing capacity, durability, and construction speed. They can resist large bending, shear, and compressive forces, ensuring the stability and safety of the building structure. In addition, due to the diverse needs of modern architecture, steel structure columns need to have the characteristic of being freely splicable to adapt to different design, height, and load requirements. This flexibility makes steel structure columns indispensable in the modern construction industry, especially in large public buildings, high-rise commercial structures, and industrial facilities, where they can easily adjust and expand the structural layout according to the design intent of the architect and the engineering requirements.
[0003] When traditional freely spliced and assembled steel structure columns are in use, they usually involve the process of welding and splicing. This splicing method requires construction workers to precisely weld the prefabricated column components on-site to ensure the overall stability and safety of the structure. First, according to the design drawings and engineering requirements, prepare the corresponding steel materials and welding equipment in advance. Before splicing, ensure that the dimensions and shapes of the column components meet the design requirements to avoid welding quality problems caused by dimensional deviations. Secondly, during the welding process, follow the welding process specifications to ensure the welding quality and strength. To prevent the heat generated by welding from deforming the column, appropriate cooling measures need to be taken. At the same time, pay attention to the visual inspection and non-destructive testing of the welds to ensure that welding defects are repaired in a timely manner.
[0004] Traditional assembled steel structure columns usually use the processes of welding and bolt splicing. Such a setting not only requires special tools for operation but also takes a long time, resulting in difficult flexible combination and adjustment during on-site construction.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0026] Referring to Figure 1 - Figure 4 , an embodiment provided by the present invention: a steel structure column that can be freely spliced and assembled, including an I-beam column 1. The bottom of the I-beam column 1 is attached to an I-beam column 2. A support assembly is provided at the bottom of the I-beam column 2 for supporting the I-beam column 2. A second fixing plate 6 is fixedly connected to the outer wall of the I-beam column 1, and a first fixing plate 5 is fixedly connected to the outer wall of the I-beam column 2. A positioning sleeve 7 is fixedly connected to the inside of the second fixing plate 6. The outer wall of the positioning sleeve 7 slides inside the I-beam column 1. A first bearing 8 is fixedly connected to the inner wall of the positioning sleeve 7. A screw rod 9 is fixedly connected to the inner wall of the first bearing 8. A trapezoidal push block 10 is threadedly connected to the outer wall of the screw rod 9. The outer wall of the trapezoidal push block 10 slides inside the positioning sleeve 7. A triangular clamping block 11 slides on the outer wall of the trapezoidal push block 10. The outer wall of the triangular clamping block 11 slides inside the positioning sleeve 7 and the I-beam column 1. A telescopic rod 12 is fixedly connected to the inside of the triangular clamping block 11. A first spring 13 is sleeved on the outer wall of the telescopic rod 12. Both ends of the first spring 13 are fixedly connected to the inside of the triangular clamping block 11. The support assembly includes a bottom plate 3. The upper surface of the bottom plate 3 is fixedly connected to the bottom of the I-beam column 2. A support plate 4 is fixedly connected to the upper surface of the bottom plate 3. The outer wall of the support plate 4 is fixedly connected to the bottom of the I-beam column 2.
[0027] Specifically, first lift the fixing plate two 6 at the bottom of the I-beam column one 1 and the fixing plate one 5 at the top of the I-beam column two 2. At the same time, insert the positioning sleeve 7 into the inside of the fixing plate one 5. Then drive one end of the screw rod 9 to drive the screw rod 9 to rotate inside the positioning sleeve 7 through the bearing one 8. Due to the threaded relationship between the screw rod 9 and the trapezoidal push block 10, the trapezoidal push block 10 slides inside the positioning sleeve 7 as the screw rod 9 rotates. Thus, the two triangular clamping blocks 11 are pushed to slide inside the positioning sleeve 7 and the I-beam column one 1 through the inclined surfaces on both sides of the trapezoidal push block 10, realizing the connection between the I-beam column one 1 and the I-beam column two 2. At the same time, the spring one 13 is stretched. When the triangular clamping block 11 moves into the inside of the I-beam column one 1, due to the setting of the inclined surface of the triangular clamping block 11, the distance between the I-beam column one 1 and the I-beam column two 2 gradually decreases, and finally a fully fitted connection is achieved. During disassembly, only need to rotate the screw rod 9 in the reverse direction. At this time, the spring one 13 is no longer stressed and rebounds, thereby pulling the triangular clamping block 11 back into the inside of the positioning sleeve 7, realizing the installation and disassembly of the I-beam column one 1 and the I-beam column two 2.
[0028] Refer to Figure 1 , Figure 5 and Figure 6 , limit holes 21 are opened inside both the I-beam column one 1 and the I-beam column two 2. Sliding columns 14 are slidably connected to the outer walls of both the I-beam column one 1 and the I-beam column two 2. A sliding plate 15 is fixedly connected inside the sliding column 14. A fixing rod 16 is slidably connected inside the sliding plate 15. The outer wall of the fixing rod 16 is slidably connected inside the limit hole 21. A sliding rod 17 is slidably connected inside the fixing rod 16. A spring two 18 is sleeved on the outer wall of the sliding rod 17. Both ends of the spring two 18 are fixedly connected to the outer wall of the fixing rod 16. A rack 19 is fixedly connected to the outer wall of the fixing rod 16. A gear 20 is rotatably connected inside the sliding plate 15. The rack 19 meshes with the gear 20. A limit block 22 is fixedly connected to the outer wall of the sliding plate 15. The outer wall of the limit block 22 is slidably connected inside the I-beam column one 1 and the I-beam column two 2;
[0029] Specifically, by pressing the fixing rod 16 to slide inside the preset limit hole 21 inside the I-beam column one 1 and the I-beam column two 2, the movement of the fixing rod 16 will drive the rack 19 to slide inside the sliding plate 15. Due to the meshing of the rack 19 and the gear 20, the gear 20 is driven to rotate, and then the rack 19 on the other side is driven to move synchronously in the opposite direction, so that the fixing rods 16 on both sides move synchronously. Then, the movement of the fixing rods 16 on both sides drives the spring two 18 to contract. When the fixing rod 16 completely moves into the inside of the I-beam column one 1 and the I-beam column two 2, the sliding column 14 can be pulled to adjust the height. When it moves to the appropriate position, the fixing rod 16 is pushed by the rebound of the spring two 18 to move back into the limit hole 21 for fixation, achieving the effect of position adjustment.
[0030] Working principle: When it is necessary to use the steel structure columns that can be freely spliced and assembled, first align the bottom fixing plate II 6 of the I-beam column I 1 with the top fixing plate I 5 of the I-beam column II 2, insert the positioning sleeve 7 into the inside of the fixing plate I 5, and then rotate the screw 9. The bearing I 8 rotates within the positioning sleeve 7. Due to the thread fit between the screw 9 and the trapezoidal push block 10, the trapezoidal push block 10 slides within the positioning sleeve 7, pushing the triangular locking block 11 to slide within the positioning sleeve 7 and the I-beam column I 1 to achieve the connection of the two columns. At the same time, the spring I 13 is stretched. When the triangular locking block 11 moves into the I-beam column I 1, due to the inclined surface design of the triangular locking block 11, the distance between the two columns gradually decreases and finally fits completely. During disassembly, rotate the screw 9 in the reverse direction, the spring I 13 rebounds, and the triangular locking block 11 is pulled back into the positioning sleeve 7 to achieve rapid installation and disassembly;
[0031] In addition, press the fixing rod 16 to slide within the preset limit holes 21 of the two columns, drive the rack 19 to slide within the slide plate 15. The meshing of the rack 19 and the gear 20 causes the gear 20 to rotate, driving the other side rack 19 to move synchronously, and the fixing rod 16 moves synchronously. The movement of the fixing rod 16 causes the spring II 18 to contract. When it completely moves into the two columns, pull the sliding column 14 to adjust the height. After adjusting to the appropriate position, the spring II 18 rebounds, and the fixing rod 16 moves back into the limit hole 21 to be fixed, achieving height adjustment.
[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
