Description

Technical Field

[0001] This utility model relates to the field of box-type column and beam technology, specifically a steel structure box-type column and beam. Background Technology

[0002] Steel structures possess numerous advantages, including high strength, light weight, good seismic resistance, batch prefabrication, prefabricated installation, high construction efficiency, and recyclability. With the rapid development of steel structures, their structural forms and shapes have undergone significant changes. Box-type column-beam structures are load-bearing structural systems with box-section steel as the main components, widely used in high-rise buildings, bridges, industrial plants, and other engineering fields. As vertical load-bearing components in buildings, box-type column-beams are responsible for supporting the weight of the entire structure. Especially in high-rise buildings and long-span bridges, their excellent load-bearing capacity and stability are particularly important, ensuring the safety and reliability of the building structure. The box-section design allows box-type column-beams to withstand large loads, including vertical loads, horizontal loads, and possible torsional forces, ensuring the stability and safety of the structure. However, traditional box-type column-beam welding often requires multiple bolts for initial connection between two columns, which is difficult and time-consuming during high-altitude operations. This method is cumbersome, time-consuming, and labor-intensive. Furthermore, under long-term vibration or load, the bolts are prone to loosening, which can affect the welding effect.

[0021] 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.

[0022] Please see Figure 1-6 As shown, this utility model is a steel structure box-type column beam, including a base 1, a lower column 2, and an upper column 3. Connecting grooves 4 are fixedly connected to both sides of the lower column 2 and the upper column 3. Two buffer pads 5 are fixedly connected to the inner walls of each of the four connecting grooves 4. A snap-fit ​​half-disc 6 is rotatably connected between the inner walls of two adjacent buffer pads 5. A handle 7 is fixedly connected to the surface of each of the four snap-fit ​​half-discs 6. The two connecting grooves 4 on the left and the two connecting grooves 4 on the right are symmetrically distributed on both sides of the upper column 3 and the lower column 2. By setting the connecting grooves 4, and then rotating each snap-fit ​​half-disc 6 within its adjacent two buffer pads 5 by holding the handle 7 to a vertical distribution, the locking force on both sides is increased after the lower column 2 and the upper column 3 are initially connected, making the connection between the lower column 2 and the upper column 3 more stable, facilitating welding, eliminating the need to tighten multiple bolts, saving time and effort, and providing convenience and speed.

[0023] Both the lower beam column 2 and the upper beam column 3 have adapter slots 8 and four positioning holes 9 at their tops. The bottom of the upper beam column 3 is fixedly connected to the adapter plug 10 and the positioning rod 11.

[0024] Four positioning rods 11 are provided and are arranged in a rectangular array at the bottom edge of the upper beam column 3.

[0025] A stabilizing block 12 is fixedly connected to the top of the base 1, and the lower beam column 2 and the stabilizing block 12 are compatible with each other.

[0026] The buffer layer 5 is made of nylon, which has good wear resistance, reducing wear between the snap-on half-disc 6 and the buffer layer 5 during rotation and extending its service life. The material also has a certain degree of friction, preventing the snap-on half-disc 6 from rotating on its own or providing cushioning when impacted, thus preventing it from spinning. Furthermore, nylon is corrosion-resistant and chemical-resistant, maintaining stability in harsh environments and resisting aging or deformation, ensuring the long-term performance of the buffer layer 5. Both the lower beam column 2 and the upper beam column 3 are made of steel. Steel has a high strength-to-weight ratio, allowing the lower beam column 2 and upper beam column 3 to reduce their weight while maintaining structural strength. This helps reduce the overall structural load, improves the building's load-bearing capacity, and may lower the requirements for the foundation. The steel structure can absorb energy when subjected to impact or vibration, reducing the risk of damage. This characteristic gives the lower beam column 2 and upper beam column 3 better seismic and wind resistance under dynamic loads such as earthquakes and wind loads, improving structural safety. The steel structure material is easy to cut, weld, and assemble, making the processing and installation of the lower beam column 2 and upper beam column 3 more efficient. This helps shorten the construction period, reduce construction costs, and improve construction flexibility. With appropriate anti-corrosion treatment (such as spraying anti-corrosion coatings, galvanizing, etc.), the steel structure material can be used for a long time without easily being damaged, which improves the durability of the lower beam column 2 and upper beam column 3, reduces maintenance costs, and extends the service life of the structure. Moreover, the steel structure material is recyclable, meeting the requirements of environmental protection and sustainable development. Using steel structure materials for the lower beam column 2 and upper beam column 3 helps reduce construction waste and reduce environmental impact. Although the initial investment in steel structure materials may be slightly higher than some other materials, its long-term benefits are significant. Due to the durability and low maintenance costs of steel structure materials, as well as the improved construction efficiency, from a total life-cycle cost perspective, steel structure materials often have a higher cost-effectiveness.

[0027] The adapter plug 10 and the adapter slot 8 are compatible with each other, and the four positioning rods 11 are slidably connected to the adjacent positioning holes 9 respectively.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] The working principle of this utility model is as follows: First, insert the four positioning rods 11 and the adapter plugs 10 into the inner walls of the four positioning holes 9 and the adapter slots 8 on the top of the lower beam column 2 to quickly install the upper beam column 3 on the lower beam column 2, achieving a preliminary connection. After establishing a preliminary connection between them, grasp the two handles 7 on the left and pull them up, causing the two handles 7 to drive the two snap-fit ​​half-discs 6 to rotate between the inner walls of the four buffer pads 5, so that the two snap-fit ​​half-discs 6 rotate from a horizontal distribution state to a vertical distribution state. Then, continue this operation by grasping the two handles 7 on the right and rotating them, so that the two snap-fit ​​half-discs 6 on the right also rotate to a vertical distribution state, allowing the four snap-fit ​​half-discs 6 to provide left and right locking force, further strengthening and stabilizing the connection between the lower beam column 2 and the upper beam column 3. The stable connection prevents the lower beam column 2 and the upper beam column 3 from loosening during welding. Then, the welding operation is performed. Finally, the positions of the four connecting slots 4 are cut off, and the original positions of the four connecting slots 4 are welded to achieve complete welding.
