[0002] Steel structures are building structures made primarily of steel, connected by welding, bolting, or riveting. They include steel beams, steel columns, steel trusses, and other components. These components are connected together to form a complete structural system. Steel structures have many unique properties and advantages and are widely used in industrial and civil buildings, bridges, towers, and other fields. Temporary fixing devices to prevent steel structure overturning are key tools used during construction to ensure the stability and safety of steel structures, effectively preventing component overturning and ensuring construction safety.

[0003] Existing fixing devices typically weld components to the main column and then cut and dismantle them after completion. Since cutting tools are required to dismantle welded components, the time and cost of dismantling are increased. Furthermore, the cut components usually leave cutting marks and damage, which affects the reuse of the components and reduces the overall performance. Utility Model Content

This device requires cutting tools to dismantle welded components, increasing the time and cost of dismantling. Furthermore, the cut components usually leave cutting marks and damage, affecting their reuse and reducing the overall performance.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] Steel possesses exceptionally high tensile and compressive strength, meaning that steel structures can maintain stable performance under heavy loads. For example, in the construction of large bridges, steel structures can withstand complex loads including vehicles, pedestrians, and the weight of the structure itself, ensuring the long-term stability and safety of the bridge. Furthermore, steel structures have good toughness, allowing them to withstand significant deformation without brittle failure. This gives steel structures excellent earthquake and wind resistance in the face of natural disasters such as earthquakes and strong winds. In earthquake-prone areas, steel structures, due to their good ductility, can dissipate energy through deformation during earthquakes, reducing structural damage.

[0022] Steel structures are relatively lightweight. While steel has a higher density than concrete, its high strength allows for smaller cross-sectional dimensions to meet the same load-bearing requirements. This results in a lighter overall weight, a significant advantage in high-rise buildings and large-span structures. For example, in the roof structure of a large-span stadium, using a steel structure reduces the roof's weight, thereby lowering the foundation's load-bearing pressure and improving the structure's seismic performance. The lighter weight also makes steel structures easier to transport and install, reducing construction costs and complexity.

[0023] In terms of construction, steel structures are characterized by their rapid construction speed. Steel structure components are generally prefabricated in factories, ensuring high precision and quality. After being transported to the construction site, these prefabricated components are quickly assembled using welding, bolting, and other methods. This construction method significantly shortens the construction cycle. For example, in the construction of some industrial plants, the construction speed of steel structures is much faster than that of traditional concrete structures, enabling the main structure to be erected in a shorter time, creating favorable conditions for enterprises to start production ahead of schedule. Furthermore, steel structure construction is less affected by seasons and weather. In cold winters or rainy seasons, as long as appropriate protective measures are taken at the construction site, the installation of steel structures can still proceed normally, unlike concrete structures which are easily affected by low temperatures and rain, making construction impossible.

[0024] Steel structures have a wide range of applications. In the construction field, they are used in high-rise buildings, large-span stadiums, airport terminals, and large shopping malls. Using steel structures in high-rise buildings reduces the building's weight and increases usable floor space; steel structures in the roofs of large-span stadiums enable large-span column-free spaces, providing excellent views and activity areas for spectators. In bridge engineering, steel structure bridges have advantages such as strong spanning capacity and fast construction speed, making them suitable for bridge construction across rivers, canyons, and other complex terrains. Furthermore, steel structures are widely used in industrial plants, tower and mast structures, offshore platforms, and many other fields. Using steel structures in industrial plants allows for easy installation of crane beams and other equipment, meeting the needs of industrial production; steel structures in tower and mast structures, such as television towers and communication towers, ensure structural stability and height requirements; and steel structures in offshore platforms can withstand various loads in the marine environment, such as wave forces and wind forces.

[0025] Steel structures are a high-performance and widely used structural form. With their advantages such as high strength, light weight, fast construction speed, and good economy, they play a vital role in modern engineering construction. However, it is also necessary to take corresponding measures to address their shortcomings, such as corrosion resistance and fire resistance, in order to fully utilize the advantages of steel structures and ensure their safety and durability.

[0026] Temporary fixing devices to prevent steel structure overturning are safety devices used during steel structure construction to ensure structural stability and prevent overturning caused by external forces. They typically feature easy installation and reusability, effectively ensuring safety and stability during construction. Common devices include combined anti-tilting steel beam temporary fixing devices, which consist of a steel base, steel column brackets, and a steel beam. The bottom of the steel base has a reinforcement mechanism, and the outer wall of the steel beam has a support mechanism symmetrically distributed on both sides of the beam. These mechanisms are connected by ear plates and horse plates, and fixed using mounting bolts and fastening sleeves. This design effectively prevents lateral tilting and falling of the steel beam before welding, while reducing the amount of temporary connection measures and lowering construction costs. Other devices include steel structure support structure anti-tilting devices, used during steel structure construction. In particular, during the installation of steel columns and beams, reliable temporary fixing measures are required. For example, before the steel columns are properly aligned and fixed in place, the bottom of the steel columns must be temporarily fixed with bolts, welding, or wooden plugs, and the upper part must be fixed with guy ropes. This device can effectively prevent the steel columns and beams from overturning due to external forces during installation. I-beam anti-tipping devices are also a common type of temporary fixing device. Due to their high web and narrow flanges, I-beams are prone to overturning due to external forces on the construction site. By using steel structure limit frames and multiple support points, the overturning of the bridge during descent is prevented. These temporary fixing devices, through different design principles and technical means, effectively improve the stability and safety of steel structures during construction and reduce the risks caused by overturning accidents.

[0027] like Figures 1-5 As shown, the temporary fixing device for preventing the steel structure from overturning includes a support column 1 and a connecting rod 2. The upper end of the support column 1 is equipped with a connecting rod 2 for supporting the load. A spherical support 7 is installed inside the upper end of the support column 1. Several sets of limiting pins 8 are circumferentially fixed at one end of the connecting rod 2. The spherical support 7 has connecting holes for accommodating the limiting pins 8. The connecting rod 2 is fixed to the spherical support 7 by inserting it through several sets of limiting pins 8. A connecting pipe 5 is installed inside the connecting rod 2. Several sets of positioning rods 4 are welded to one end of the connecting pipe 5. Multiple sets of limiting bolts 6 are provided on the outer wall of the connecting rod 2. The connecting pipe 5 has connecting holes for accommodating the limiting bolts 6. The connecting rod 2 is threadedly fixed to the connecting pipe 5 through multiple sets of limiting bolts 6.

[0028] Please see Figures 2-4Multiple sets of support rods 3 are welded to the outer wall of the connecting rod 2. The multiple sets of support rods 3 are welded and fixed to several sets of positioning rods 4. A crossbeam 9 is fixed inside the support column 1. Two sets of brackets 10 are installed at the lower end of the crossbeam 9 on the outer wall of the support column 1. Screws are installed inside the crossbeam 9. The crossbeam 9 is threadedly limited to the two sets of brackets 10 by the screws. A column 11 is symmetrically welded to the upper end of the crossbeam 9. Screws 12 are provided at the ends of the two sets of brackets 10 away from the crossbeam 9. The brackets 10 have limiting holes for accommodating the screws 12. The brackets 10 are fixedly connected to the support column 1 by the screws 12.

[0029] Please see Figures 3-5 The lower end of the support column 1 is provided with an adjusting rod 13. Both the adjusting rod 13 and the lower end of the support column 1 are welded with splicing columns 16. The upper end of the adjusting rod 13 is provided with a positioning hole to accommodate the splicing column 16. The support column 1 is connected to the adjusting rod 13 by the splicing column 16. The outer wall of the support column 1 is fitted with a clamp 14. The support column 1 is firmly attached to the adjusting rod 13 by the clamp 14. The lower end of the adjusting rod 13 is installed with a base 17. Both the base 17 and the adjusting rod 13 are provided with two sets of limiting rods 15. The adjusting rod 13 is connected and fixed to the base 17 and the support column 1 by the two sets of limiting rods 15.

[0030] When temporary fixed support is required for the steel structure, the base 17 is first moved to the designated area. Based on the support height of the steel structure, an adjustable rod 13 of suitable height is selected and inserted into the base 17 along with the splicing column 16. It is then fixed by screws 12 and limiting rods 15. After the adjustable rod 13 suitable for the temporary support height is installed, the connecting rod 2 is connected to the upper spherical support 7 of the support column 1 using limiting pins 8 for insertion and limiting. After the connecting rod 2 is installed, limiting bolts 6 are inserted into the connecting rod 2 and threadedly assembled with the support rod 3 and connecting pipe 5. Simultaneously, screws 12 and bolts are used to fix the bracket 10 to the support column 1 and the beam 9. After the support column 1 components are installed sequentially, the splicing column 16 is used to connect the support column 1 to... The adjusting rod 13 is inserted into the limiting position, and the limiting rod 15 is inserted into the adjusting rod 13 and connected to the splicing column 16. After the limiting rod 15 is inserted into the fixed support column 1, the clamp 14 is fitted onto the outer wall of the support column 1 to make it fit and position with the adjusting column. The connecting components are assembled and fixed in a prefabricated manner. The assembly is carried out according to certain rules, so that the temporary fixing work of the entire steel structure can be completed in a short time, which speeds up the construction progress. At the same time, the prefabricated installation support is installed, and no complicated cutting and destruction operations are required during dismantling, which realizes the rapid dismantling of components. Moreover, by dismantling the prefabricated components, the damage to the components can be reduced. After simple cleaning and inspection, the components can be reused, realizing the reuse of components.
