Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building structures, in particular to a butt welded structure of a cross-shaped steel structure. Background Art
[0002] The unique shape of the cross-shaped steel structure enables it to effectively resist bending moments from two mutually perpendicular directions. In the building structure, when the building is subjected to horizontal wind loads or earthquakes, the columns can play a bending-resistant role in both main axis directions, thereby providing stable support for the building.
[0003] Cross-shaped steel structures are often the main vertical load-bearing components in buildings and engineering structures. Butt welding can effectively connect two sections of columns into a whole to ensure the continuity of the structure. The two cross-shaped steel structures need to be aligned and then fixed during welding. Therefore, we need to design a butt welding structure for cross-shaped steel structures. The use of a movable clamping structure and fixing measures can limit the free expansion and contraction of the columns during the welding process, thereby significantly reducing the deformation during welding and preventing the columns from bending or twisting at will during welding. It can ensure that after the weld cools, the geometric shape of the column still meets the design requirements, avoiding bending and twisting that affect the structural performance, and improving the quality of the cross-shaped steel structure during butt welding.

[0024] Hereinafter, embodiments of a butt-joint welding structure of a cross-shaped steel structure according to the present invention will be described with reference to the accompanying drawings.

A spring 9 is provided, and the two ends of the spring 9 are welded to the inner cavity of the fixed cover 3 and the right side of the connecting plate 5 respectively. Through the setting of the spring 9, the spring 9 can effectively absorb and buffer the impact force of the connecting plate 5 when sliding. The elastic restoring force of the spring 9 can make the connecting plate 5 return to its original position. The spring 9 can also play a buffering role in the inner cavity of the fixed cover 3, thereby maintaining the stability of the structure. The top of the connecting plate 5 is fixedly connected with a handle 10, which passes through the top of the fixed cover 3 and is slidably connected to the fixed cover 3. Through the handle 10, the connecting plate 5 drives the mounting block 11 to slide. The connecting plate 5 plays a guiding role, ensuring that the mounting block 11 will not have position deviation when sliding, thereby improving the stability of the mounting block 11 during the sliding process. The left side of the connecting plate 5 is fixedly connected to two symmetrical mounting blocks 11, which penetrate to the left side of the fixed cover 3 and are slidably connected to the fixed cover 3. A square groove is provided on the opposite side of the two mounting blocks 11, and a spring 2 12 is provided in the inner cavity of the square groove. A clamping plate 13 is slidably connected to the bottom of the inner cavity of the square groove. The two ends of the spring 2 12 are welded to the clamping plate 13 and the mounting block 11 respectively. The two clamping plates 13 are tightly connected to the cross-shaped steel structure 2 The limit blocks 14 are fixedly connected to the front and rear sides of the inner cavity of the fixed cover 3, and the two limit blocks 14 are slidably connected to the connecting plate 5 on the opposite side. Through the setting of the limit blocks 14, the limit blocks 14 limit the connecting plate 5 when the connecting plate 5 slides in the inner cavity of the fixed cover 3, ensuring that the connecting plate 5 will not shift its position when sliding, thereby improving the stability of the connecting plate 5 when sliding.

[0026] Working principle: When the present invention is used, the user aligns the two sides of the cross-shaped steel structures 2 that need to be welded, and then places the fixing cover 3 on one side of the cross-shaped steel structure 2. Then, the left side of the fixing cover 3 is tightly fitted with the right side of the cross-shaped steel structure 2. Then, the user pulls the handle 10, and the handle 10 drives the connecting plate 5 to slide in the inner cavity of the fixing cover 3, so that the connecting plate 5 drives the two sliding blocks 6 to slide in the inner wall of the track 4. At the same time, the connecting plate 5 drives the connecting rod 8 to slide in the inner cavity of the fixing sleeve 7 when sliding, and then the spring 9 of the connecting plate 5 will rebound when sliding. The property becomes longer inside the fixed cover 3, and at the same time, the connecting plate 5 will drive the two mounting blocks 11 to slide to the left when sliding, and then the mounting block 11 will drive the clamping plate 13 to slide on the surface of the cross-shaped steel structure 2. When the clamping plate 13 slides to the surface of the cross-shaped steel structure 2 and breaks away from the contact with the surface of the cross-shaped steel structure 2, the clamping plate 13 will slide at the bottom of the square groove opened in the mounting block 11, and the clamping plate 13 will fix the two clamping plates 13 to the cross-shaped steel structure 2. At this time, the butt joints of the two cross-shaped steel structures 2 are fixed, and finally the user will weld the butt joints of the cross-shaped steel structures 2.
[0027] To sum up: the butt-joint welding structure of the cross-shaped steel structure is achieved by aligning the two cross-shaped steel structures 2, fitting the fixed cover 3 tightly with the cross-shaped steel structure 2 on one side, and then using the connecting plate 5, the sliding block 6 and the spring 9 in combination, so that the connecting plate 5 will drive the two mounting blocks 11 to slide, and then the clamping plate 13 will fix the cross-shaped steel structure 2, so as to achieve the purpose of adopting a movable clamping structure and fixing measures, which can limit the free expansion and contraction of the column during the welding process, thereby significantly reducing the deformation during welding, so that the column cannot bend or twisted at will during welding, and can ensure that after the weld is cooled, the geometric shape of the column still meets the design requirements, avoiding bending and twisting that affect the structural performance, and improving the quality of the cross-shaped steel structure during butt-joint welding.
