Description

Technical Field

[0001] The invention relates to the technical field of steel structure auxiliary welding, in particular to an auxiliary structure for building steel structures of construction projects. Background Art

[0002] Steel structures have excellent strength and rigidity, and can withstand large loads and external forces, providing greater safety reserves for buildings and ensuring structural stability. In natural disasters such as earthquakes and wind disasters, steel structures show excellent earthquake and wind resistance, effectively ensuring the safety of buildings. Compared with traditional concrete structures, steel structures have a lighter weight, which reduces the overall weight of the building, thereby reducing the load on the foundation, reducing construction costs, and helping to improve construction efficiency. At the same time, steel structural components can be easily cut, bent, and welded, making steel structures more flexible and able to meet different building forms and functional requirements.

[0003] The roof is an important part of the building. It not only has the function of sheltering from wind and rain, but also affects the overall aesthetics of the building. Steel structure roofs have the advantages of light weight, high strength, and short construction period. They are often used in large public buildings, industrial plants, etc. Under the premise of geometric structure and mechanical properties, triangles are more stable than other shapes. Therefore, when welding steel structure roofs, the triangle fixed welding method can significantly improve the overall stability of the steel structure. In steel structures, triangular structures can effectively resist various external forces and deformations to ensure the stability and safety of the structure. In the prior art, strong magnetic fixtures are generally used for welding assistance for steel structure welding. The resulting disadvantage is that the strong magnetic fixture may generate magnetic field interference during the welding process, affecting the stability of the welding arc and the formation of the weld, and the angle of the strong magnetic fixture is a fixed angle. This may cause defects such as uneven welds, slag inclusions, pores, and mismatches between welding angles, reducing the strength and sealing of the weld. In addition, due to the need for inclined welding between steel structures, it may not be as efficient as other shapes during welding, so it is necessary for construction personnel to adjust the welding angles many times, causing inconvenience in construction.

DETAILED DESCRIPTION

[0020] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0022] like Figures 1 to 8 As shown, the present application provides an auxiliary structure for the construction of steel structures for construction projects, including: a base 1, which is the foundation of the entire structure, and provides a stable support surface to ensure that the upper steel structure can stand firmly on it. A steel structure 2 is arranged on the base 1, and the steel structure 2 is the main supporting member on the roof. Through one or more steel columns, which are used to bear the weight and load of the upper structure, a steel structure 2 3 is inclinedly arranged on the side wall of one side of the steel structure 2, and the steel structure 2 3 is inclinedly arranged on the side wall of one side of the steel structure 2, and a triangular geometry is formed by interconnecting with other steel structures. This inclined setting is used to increase the stability of the structure, or to meet specific space requirements to ensure coordinated work with the steel structure 2.

[0023] like Figures 1 to 8 As shown, an auxiliary structure for building steel structure of a construction project also includes: a fixing mechanism 4, the fixing mechanism 4 is arranged on the steel structure 2, the fixing mechanism 4 includes a support plate 5 arranged on the base 1, a fixing plate 6 is fixedly arranged on the support plate 5, a slide groove 7 is opened on the support plate 5, a slider 8 is slidably arranged in the slide groove 7, and the fixing mechanism 4 is used for vertical fixing of the steel structure 2; Through the design of the support plate 5 and the fixing plate 6 as well as the slide groove 7 and the slider 8, the auxiliary structure can flexibly fix and adjust the position of the steel structure 2 in the vertical direction, thereby improving the efficiency and accuracy of the construction. The overall design of the fixing mechanism 4 ensures the stability of the steel structure 2 during the welding process of the construction, and prevents safety problems caused by shaking or displacement. In the construction of high-rise steel structures, the auxiliary structure can be used to fix and adjust the position of steel structural parts to ensure the accuracy and safety of the construction process.

[0024] like Figures 1 to 8 As shown, an auxiliary structure for building a steel structure of a construction project, further comprising: a fixing mechanism 16, the fixing mechanism 16 is arranged on the steel structure 3, the fixing mechanism 16 comprises a supporting plate 17 arranged on a side wall of one side of the steel structure 3, a fixing plate 18 is fixedly arranged on the supporting plate 17, a sliding groove 23 is provided on the supporting plate 17, a sliding block 24 is slidably arranged in the sliding groove 23, and the fixing mechanism 16 is used for the inclined multi-angle fixing of the steel structure 3; Through the cooperation between the slide groove 23 of the fixing mechanism 216 and the slider 24, the steel structure 23 is fixed at multiple angles in the tilting direction, which increases the flexibility and adaptability of the construction. The setting of the fixing plate 218 strengthens the connection between the steel structure 23 and the support plate 217, and improves the overall stability of the structure. The sliding design of the slider 24 in the slide groove 23 allows the tilting angle of the steel structure 23 to be easily adjusted as needed, thereby improving the construction efficiency. The angle between the steel structure 23 and the steel structure 12 can be flexibly adjusted according to the construction requirements. This flexibility not only improves the construction efficiency, but also enables the auxiliary structure to be applied to various complex construction scenes.

[0025] The end of the steel structure 2 3 is attached to the side wall of the steel structure 1 2, and a rotating assembly 29 is also provided on the base 1, and the rotating assembly 29 is used to rotate the workpiece on the base 1 as a whole. The setting of the rotating assembly 29 enables the workpiece on the base 1 (including the steel structure 1 2 and the steel structure 2 3) to rotate as a whole. This design increases the flexibility of construction, allowing construction personnel to adjust the direction and angle of the workpiece as needed.

[0026] Please refer to Figures 1 to 3 as well as Figure 5The inner walls of the slide groove 17 and the slide groove 23 are fixedly provided with a limiting cylinder 19, and the outer surface of the limiting cylinder 19 is slidably connected to the limiting cylinder 210, and the end of the limiting cylinder 210 away from the limiting cylinder 19 is fixed to the side walls of the slide groove 17 and the slide groove 23, and the inner walls of the limiting cylinder 19 and the limiting cylinder 210 are provided with a spring 11. The support plate 15 is fixedly provided with a fixing bolt 12 and a fixing bolt 213, and the middle parts of the fixing bolt 12 and the fixing bolt 213 are threadedly connected with a screw rod 14, and one end of the screw rod 14 is fixedly provided with a rotating handle 15, and the end of the screw rod 14 away from the rotating handle 15 is in contact with the side wall of the slider 18.

[0027] By rotating the handle 15, the screw 14 can be driven to move in the fixing bolt 12 and the fixing bolt 2 13, thereby fixing or adjusting the position of the slider. This design enables the slider to accurately adjust its position in the slideway to meet different construction requirements. The fixing effect of the screw 14 enhances the connection strength between the slider and the support plate 5, and improves the stability of the overall structure. The design of the handle 15 makes the rotation operation of the screw 14 more convenient, reducing the construction difficulty and labor intensity.

[0028] In addition, the spring 11 provided on the inner wall of the limiting cylinder 1 9 and the limiting cylinder 2 10 can make the slider 1 8 and the slider 2 24 automatically reset when the welding is finished. When the slider 1 8 or the slider 2 24 slides to the desired position in the slide groove 1 7 and the slide groove 2 23 and is welded, the screw 1 14 and the screw 2 27 will squeeze the slider 1 8 and the slider 2 24 during the welding process, causing the spring 11 to deform and the slider may temporarily deviate from its final position. When the welding is finished and the squeezing force disappears, the spring 11 on the inner wall of the limiting cylinder 1 9 and the limiting cylinder 2 10 exerts its elastic effect, generating a certain thrust on the slider 1 8 and the slider 2 24, so that it can automatically reset to the predetermined position after the welding is completed.

[0029] Figures 1 to 3 as well as Figure 4 The support plate 17 is fixed with a fixing bolt 3 25 and a fixing bolt 4 26. The middle of the fixing bolt 3 25 and the fixing bolt 4 26 is threadedly connected with a screw rod 27. A rotating handle 28 is fixedly provided at one end of the screw rod 27. The end of the screw rod 27 away from the rotating handle 28 is in contact with the side wall of the slider 24. The fixing plate 1 6 is symmetrically provided with an arc groove 19 and an arc groove 20. The inner walls of the arc groove 19 and the arc groove 20 are rotatably connected with a rotating ring 21. When the rotating ring 21 rotates with the inner walls of the arc groove 19 and the arc groove 20, there is a resistance. A plurality of scale lines 22 are equidistantly provided on the rotating ring 21.

[0030] The arc groove 19 and the arc groove 20 provide a stable guide and limit function for the swivel 21, ensuring that the swivel 21 rotates smoothly on the fixed plate 16 and does not deviate from the predetermined trajectory. Similar to the fixing bolt 12, the fixing bolt 23 and the screw 14 on the support plate 15, the fixing bolt 3 25, the fixing bolt 4 26 and the screw 2 27 on the support plate 2 17 also constitute the fixing and adjustment mechanism of the slider 2 24. By rotating the handle 2 28, the screw 2 27 can be driven to move in the fixing bolt 3 25 and the fixing bolt 4 26, thereby realizing the precise adjustment and fixation of the position of the slider 2 24. The fixing effect of the screw 2 27 enhances the connection strength between the slider 2 24 and the support plate 2 17, and improves the stability of the overall structure.

[0031] Please refer to Figures 6 to 8 The rotating assembly 29 includes a mounting groove 1 30 provided on the base 1, a worm wheel 31 is rotatably provided on the inner wall of the mounting groove 1 30, and a turntable 32 is also rotatably provided on the inner wall of the mounting groove 1 30. The worm wheel 31 is externally connected to an external drive, and the turntable 32 and the worm wheel 31 are fixedly connected to each other, and the turntable 32 and the worm wheel 31 are coaxial. A mounting groove 2 33 is also provided on the base 1, and the mounting groove 2 33 is connected to the mounting groove 1 30, and a fixing block 1 34 and a fixing block 2 35 are fixedly provided on the inner wall of the mounting groove 2 33, and a worm 36 is rotatably connected to the middle of the fixing block 1 34 and the fixing block 2 35, and the worm 36 is meshedly connected to the worm wheel 31.

[0032] After the worm 36 is started by external drive, it drives the worm wheel 31 to rotate. Since the worm wheel 31 is fixedly connected and coaxial with the turntable 32, the turntable 32 will also rotate accordingly. This transmission mode of the worm wheel 31 and the worm 36 has a large transmission ratio and self-locking property, that is, when the worm 36 stops rotating, the worm wheel 31 cannot rotate in the opposite direction by itself, thus ensuring the stability and reliability of the transmission. During welding, it ensures that the workpiece above the base 1 will not be displaced, and at the same time, it can realize accurate control of the construction process, thereby improving the construction efficiency and accuracy.

[0033] Through all the above embodiments, the working principle of the present invention is specifically as follows: First, place the device in an open operating area, and then place the steel structure 2 on the side wall of the support plate 5 above the turntable 32 and fit it with the fixed plate 6. At this time, rotate the handle 15 to cause the screw 14 to rotate and make a linear motion. The end of the screw 14 gradually fits and squeezes the slider 8 to slide in the slide groove 7. When the side wall of the slider 8 fits with the steel structure 2, it stops rotating. The steel structure 2 is stably fixed between the fixed plate 6 and the slider 8. Through the design of the support plate 5 and the fixed plate 6 and the slide groove 7 and the slider 8, the auxiliary structure can flexibly fix and adjust the position of the steel structure 2 in the vertical direction, thereby improving the efficiency and accuracy of the construction. The overall design of the fixing mechanism 4 ensures the stability of the steel structure 2 during the welding process and prevents safety problems caused by shaking or displacement. In the construction of high-rise steel structures, the auxiliary structure can be used to fix and adjust the position of steel structural members to ensure the accuracy and safety of the construction process; Further, rotate the rotating ring 21 on the fixed plate 16 and observe the scale line 22. After rotating to the appropriate position, place the steel structure 23 on the side wall of the support plate 217 and fit it with the fixed plate 218. At the same time, push the steel structure 23 to fit with the side wall of the steel structure 2. At this time, rotate the handle 28 to cause the screw 27 to rotate and make a linear motion. The end of the screw 27 gradually fits and squeezes the slider 24 to slide in the slide groove 23. When the side wall of the slider 24 fits with the steel structure 2, stop rotating. The steel structure 23 is stably fixed between the fixed plate 16 and the slider 18, and a certain angle is formed between the slider 2 and the steel structure 2, realizing the multi-angle fixation of the steel structure 23 in the inclined direction, increasing the flexibility and adaptability of the construction. The setting of the fixed plate 218 strengthens the connection between the steel structure 23 and the support plate 217, and improves the overall stability of the structure. The sliding design of the slider 24 in the slide groove 23 allows the inclination angle of the steel structure 23 to be easily adjusted as needed, thereby improving the construction efficiency. The angle between steel structure 2 3 and steel structure 1 2 can be flexibly adjusted according to construction requirements, thereby improving construction efficiency; Furthermore, after the welding of one side of the steel structure 1 2 and the steel structure 2 3 is completed, the worm 36 is started by external drive to drive the worm wheel 31 to rotate. Since the worm wheel 31 is fixedly connected and coaxial with the turntable 32, the turntable 32 will also rotate accordingly, so that the steel structure 1 2 and the steel structure 2 3 above the turntable 32 are displaced and rotated to the unwelded side for welding. The transmission method of the worm wheel 31 and the worm 36 has a large transmission ratio and self-locking property, that is, when the worm 36 stops rotating, the worm wheel 31 cannot rotate in the opposite direction by itself, ensuring the stability and reliability of the transmission. When welding, it is ensured that the workpiece above the base 1 will not be displaced, and at the same time, precise control of the construction process can be achieved.

[0034] A person skilled in the art should understand that the discussion of any of the above embodiments is only exemplary; within the scope of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.

[0035] The present invention is intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
