Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a deformation control device for box-type steel structures. Background Technology

[0002] In recent years, steel structures have been widely used in the construction industry. During the construction of steel structures, welding technology requires high temperatures to achieve the desired welding effect. During heating, the melting point of the metal to be welded must be reached first, and then the temperature must be lowered to room temperature to complete the welding process. When the temperature reaches the melting point, the metal expands rapidly, but the surrounding area does not reach the same temperature. The two fuse together, and the weld joint will deform due to uneven expansion. This phenomenon, which seems inevitable in welding, can greatly affect the progress and quality of the project. At the same time, the load-bearing capacity of the steel structure will also be greatly reduced.

[0003] Based on this, the present invention designs a deformation control device for box-type steel structures to solve the above problems. Summary of the Invention

[0025] Please see Figure 1-7 This invention provides a technical solution: a deformation control device for a box-type steel structure, characterized in that: it includes a base 1, which is composed of two finished square tubes with a cross-section of 600*600*20mm and a length of 1500mm, with a distance of 7500mm between the two square tubes; a 15m long 60-type H-beam is placed longitudinally on the top of the base 1 as an operating platform 2; the operating platform 2 is equipped with a clamping plate assembly and a limiting mechanism; the clamping plate assembly is used to position the box column, and the limiting mechanism is used to limit the side plate of the box column during welding.

[0026] like Figure 2 As shown, the clamping plate assembly consists of a positioning plate 3, a connecting plate 4, and a pressure plate 5. The positioning plate 3 is made of a steel plate with dimensions of 150*1000*20mm. Two holes with a diameter of 20mm are cut on the top of the steel plate, 40mm from the top, and 100mm apart, serving as bolt fixing holes. The positioning plate 3 is hinged to the connecting plate 4 by bolts. The connecting plate 4 is made of a steel plate with dimensions of 150*300*20mm. The pressure plate 5 is hinged to the connecting plate 4 by bolts. The pressure plate 5 is made of a steel plate with dimensions of 50*100*15mm.

[0027] like Figure 1 As shown, the clamping plate assembly consists of 11 sets, which are evenly arranged on the side wall of the operating table 2 at a spacing of 1500mm. The positioning plate 3 is fixed to the operating table by welding. The steel plate material selected for the positioning plate 3, connecting plate 4 and pressure plate 5 is Q235B or above.

[0028] like Figure 3As shown, the limiting mechanism includes a fixed pad 6, a fixed upright plate 7, and a fixed screw 8. The fixed pad 6 is made of a steel plate with dimensions of 150*400*12mm. A waist-shaped hole is opened in the middle of the fixed pad 6 as an adjustable hole. The fixed pad 6 is installed on the top of the operating table 2 and fixed by bolts to facilitate adjustment of the distance between the fixed pad 6 and the box column. The fixed upright plate 7 is welded and fixedly connected to the top of the fixed pad 6. The fixed upright plate 7 and the fixed pad 6 are reinforced by a triangular support. A nut is welded on the fixed upright plate 7, and the fixed upright plate 7 is threadedly connected to the fixed screw 8 through the nut.

[0029] like Figure 1 As shown, there are 11 sets of limiting mechanisms. The 11 sets of limiting mechanisms are evenly arranged on the top of the operating table 2 at a spacing of 1500mm. The limiting mechanisms are located on the side of the clamping plate assembly.

[0030] like Figure 3 As shown, the fixing pad 6 has a wedge-shaped surface at one end near the positioning plate 3, and a wedge block 9 that mates with the wedge-shaped surface is provided on the side of the fixing pad 6.

[0031] like Figure 3 As shown, a first handle 10 is installed at the end of the fixing screw 8 away from the fixing plate 7.

[0032] In practice, the assembled left, right, and front side panels and base plate of the box column are first placed on the top of the workbench 2, so that one side wall of the box column is in contact with the positioning plate 3. When welding the rear side panel of the box column, the rear side panel is placed against the rear of the box column. Then, the operator rotates the first handle 10 to drive the fixing screw 8 to rotate synchronously, and the fixing screw 8 will move closer to the box column. In actual use, the moving distance of the fixing screw 8 can be adjusted according to the model of the box column. The fixing screw 8 will press the rear side panel tightly against the rear of the box column. Then, the operator uses the wedge block 9 to continuously wedge inward. At this time, the fixing screw 8 and the wedge block 9 contact the rear side panel synchronously. Through the cooperation of the fixing screw 8 and the wedge block 9, it can be ensured that the rear side panel is in contact with the box column without bending, thus ensuring... The box column will not deform during welding; after the bottom plate and the rear side plate are welded, the top cover plate is put on, and then the connecting plate 4 and the pressure plate 5 are folded upwards, so that the pressure plate 5 is stuck on the top of the box column, thereby achieving the purpose of the top cover plate being unable to move. Then, the workers fix the top cover plate by spot welding. The present invention, through the setting of the clamping plate assembly and the limiting mechanism, can position the side plate when welding the side plate of the box column. At the same time, through the abutment of the wedge block 9, it can ensure that the side plate will not bend or deform during welding. When welding the top cover plate of the box column, the clamping plate assembly can press on the cover plate to prevent the cover plate from shifting or deforming. The device of the present invention is simple to manufacture, has no complexity, occupies a small area, has a high utilization rate, is safe and reliable, has good overall stress performance, and has low manufacturing cost.

[0033] As a further embodiment of the present invention, such as Figure 3 and Figure 4 As shown, a positioning frame 11 is provided above the fixing screw 8. The positioning frame 11 is U-shaped, and a rotating rod 12 is installed on the positioning frame 11. The rotating rod 12 is sleeved with the fixing plate 7. A first spring 13 is fitted on the rotating rod 12. The end of the first spring 13 away from the rotating rod 12 is fixedly connected to the fixing plate 7. A first push plate 14 is fixedly connected to the rotating rod 12. A second push plate 15 is provided on the side of the first push plate 14, which can push it to move. The second push plate 15 is rotatably connected to the fixing screw 8. The second push plate 15 is slidably connected to the fixing plate 7.

[0034] In practice, the positioning frame 11 is positioned above the fixing screw 8. After the rear side plate of the box column is placed in the welding position, before rotating the fixing screw 8, the operator first rotates the rotating rod 12, causing the rotating rod 12 to rotate the positioning frame 11 180°. After the positioning frame 11 rotates 180°, the opening of the positioning frame 11 faces downward, and the top of the box column side plate is located inside the opening of the positioning frame 11. The positioning frame 11 and the box column side plate are in clearance fit. The positioning frame 11 restricts the box column side plate so that it will not fall over after being placed in the welding position. It will tilt slightly due to the clearance fit, but the box column side plate can be inserted into the inside of the positioning frame 11. While the rotating rod 12 is rotating, it will drive the first push plate 14 to rotate synchronously, and the top of the first push plate 14 will rotate downward. When the worker rotates the fixing screw 8 to move it closer to the side plate of the column, the fixing screw 8 will drive the second push plate 15 to move synchronously. When the second push plate 15 moves to contact the first push plate 14, the fixing screw 8 moves to the position where it is in contact with the side plate of the column. At this time, the fixing screw 8 will push the inclined side plate of the column to a vertical position, and the side plate of the column will be in contact with the inner wall of the positioning frame 11. If the fixing screw 8 needs to be fed again due to production errors, the fixing screw 8 will drive the positioning frame 11 to move synchronously through the second push plate 15 and the first push plate 14. This can ensure that the side plate of the column always remains vertical between the fixing screw 8 and the positioning frame 11 and will not bend or deform. This makes it easier to fix and weld the side of the column.

[0035] As a further embodiment of the present invention, such as Figure 3 As shown, a second grip 16 is installed at the end of the rotating rod 12.

[0036] In actual operation, the second grip 16 makes it easier for the operator to rotate the lever 12.

[0037] As a further embodiment of the present invention, such as Figure 2 , Figures 4-6 As shown, a fixing plate 17 is fixedly installed on the fixing plate 7. A first sliding groove 18 is provided on the fixing plate 17. The first sliding groove 18 is inclined. A sliding column 19 is slidably installed in the first sliding groove 18. A second spring 20 is fixedly connected to the sliding column 19. The end of the second spring 20 away from the sliding column 19 is fixedly connected to the fixing plate 17. A pressure rod 21 is fixedly connected to the side wall of the pressure plate 5 near the sliding column 19. The top end of the pressure rod 21 is bent into a hook shape.

[0038] In practice, after the side plate of the box column is welded to the bottom plate, the worker rotates the rotating rod 12 to rotate the positioning frame 11 to the position with the opening facing upwards; then the worker puts on the top cover plate, and then folds the connecting plate 4 and the pressure plate 5 upwards. The pressure plate 5 will drive the pressure rod 21 to rotate synchronously. When the end of the pressure rod 21 rotates to contact the sliding column 19; Figure 6 As shown, since the end of the pressure rod 21 is designed with a beveled hook shape, when the pressure rod 21 is pressed down, it will drive the sliding column 19 to slide in the first sliding groove 18. When the pressure rod 21 is flipped to the horizontal position, the sliding column 19 will be engaged in the hook-shaped groove of the pressure rod 21 under the elastic force of the second spring 20, and the second spring 20 will apply a downward pressure to the pressure rod 21 through the sliding column 19; this can make the pressure rod 21 cooperate with the pressure plate 5 to press the top cover plate tightly. It should be noted that in actual operation, the operator can choose whether to work with all the pressure plates 5 according to the actual bending state of the cover plate. When the cover plate is relatively flat, the operator can choose any 2 to 3 pressure plates 5 to work. When the cover plate is bent at a certain position, the operator can flip multiple pressure plates 5 around the bend to cooperate with the sliding column 19. The pressure plates 5 can flatten the cover plate, which can ensure that the box column cover plate will not be bent or deformed after subsequent welding.

[0039] As a further embodiment of the present invention, such as Figure 6 As shown, the positioning frame 11 and the rotating rod 12 are slidably connected in the vertical direction. A third spring 23 for resetting is fixedly connected to the positioning frame 11. A pressure column 22 is fixedly connected to the positioning frame 11, and the pressure column 22 is located on the side of the pressure rod 21.

[0040] In actual operation, after the pressure rod 21 flips to contact the pressure column 22, the pressure rod 21 will push the positioning frame 11 downward and stretch the third spring 23 by pressing the pressure column 22. When the pressure rod 21 rotates to the horizontal position, the bottom surface of the positioning frame 11 presses on the top of the box column cover plate, which can make the cover plate better maintain a flat state during welding.

[0041] Working Principle: First, place the assembled left, right, and front side panels and bottom plate of the box column on the top of the operating table 2, ensuring one side wall of the box column is flush with the positioning plate 3. When welding the rear side panel of the box column, place the rear side panel against the rear of the box column. Then, the operator rotates the first handle 10 to drive the fixing screw 8 to rotate synchronously, causing the fixing screw 8 to move closer to the box column. In actual use, the movement distance of the fixing screw 8 can be adjusted according to the model of the box column. The fixing screw 8 will press the rear side panel tightly against the rear of the box column. Then, the operator uses the wedge block 9 to continuously wedge inward. At this time, the fixing screw 8 and the wedge block 9 simultaneously contact the rear side panel. Through the cooperation of the fixing screw 8 and the wedge block 9, it can be ensured that the rear side panel is flush with the box column without bending, thus ensuring the box column's stability. The column will not deform during welding; after the bottom plate and the rear side plate are welded, the top cover plate is put on, and then the connecting plate 4 and the pressure plate 5 are folded upwards, so that the pressure plate 5 is stuck on the top of the box column, thereby achieving the purpose of the top cover plate being unable to move. Then the workers fix the top cover plate by spot welding. The present invention, through the setting of the clamping plate assembly and the limiting mechanism, can position the side plate when welding the side plate of the box column. At the same time, through the abutment of the wedge block 9, it can ensure that the side plate will not bend or deform during welding. When welding the top cover plate of the box column, the clamping plate assembly can press on the cover plate to prevent the cover plate from shifting or deforming. The device of the present invention is simple to manufacture, has no complexity, occupies a small area, has a high utilization rate, is safe and reliable, has good overall stress performance, and has a low manufacturing cost.
