Description

Technical Field

[0001] This invention relates to the field of building construction, and in particular to a welding fixture for I-beams used in green building construction. Background Technology

[0002] I-beams, also known as steel beams, are long strips of steel with an I-shaped cross-section. They are classified into ordinary I-beams and lightweight I-beams. I-beams are mainly used in building structures, curtain wall projects, machinery manufacturing, and vehicle manufacturing. In construction projects, there are instances where an I-beam to be installed needs to be placed between two I-beams already fixed to the ceiling or a high location. Since the I-beams are of the same type, on-site manual cutting is required to partially remove the flanges of the I-beam to be installed, exposing part of the web. This allows the cut web of the I-beam to fit between the flanges of the two installed I-beams and be welded.

[0003] In existing technologies, after the I-beam flanges are cut, surface defects may exist in the cut area, making it impossible to embed the web plate into the two flanges. Grinding and repair are required, mostly done manually. After manual grinding, the flanges are spliced. Then, it is necessary to determine whether the joint is flush. If the joint is not flush, the I-beam flanges need to be ground a second time and spliced ​​again. This process requires the I-beams to be installed to be moved back and forth between the ceiling and the ground treatment area, resulting in excessively long installation time. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a welding fixture for I-beams used in green building construction.

[0005] The technical solution includes a frame that moves on an I-beam A. The frame includes a vertically arranged column, a support frame fixedly installed at the lower end of the column, a traveling wheel for moving on the I-beam on the support frame, and a set of fixing mechanisms for fixing the frame on the I-beam fixedly installed on both sides of the support frame.

[0006] The frame is also equipped with a positioning mechanism, and the positioning mechanism is detachably connected to an I-beam B.

[0007] Preferably, the positioning mechanism includes two parallel active rods, the upper ends of which are rotatably connected to the upper end of the frame, and the lower ends of the two active rods are rotatably connected by a lower connecting rod.

[0008] Each of the driving rods has a driven rod rotatably mounted at its lower end. The movable end of the driven rod is rotatably connected via an adapter frame. A connecting unit is fixedly mounted on the adapter frame, and an I-beam B is detachably mounted on the connecting unit.

[0009] An adjusting nut is rotatably mounted in the middle of one of the active rods on the side away from the frame. The adjusting nut is internally threaded to a lead screw, and the lower end of the lead screw is rotatably connected to the frame.

[0010] Preferably, a large gear is fixedly installed at the lower end of one of the drive rods located away from the frame, and a small gear is rotatably installed at the lower end of the other drive rod. The small gear is fixedly connected to the driven rod, and the large gear and the small gear mesh with each other.

[0011] Preferably, the number of teeth of the large gear is twice the number of teeth of the small gear.

[0012] Preferably, the connecting unit includes a crossbar fixedly mounted on the adapter frame, with slots opened at both ends of the crossbar, and a clamping block slidably mounted in each slot, with the two clamping blocks facing each other.

[0013] An adjusting screw is rotatably installed inside the crossbar. The two ends of the adjusting screw are respectively threaded, and the two threads of the adjusting screw are respectively threaded to one of the clamping blocks.

[0014] Preferably, the fixing mechanism includes a locking screw fixedly mounted on the frame, and a clamping arm is rotatably mounted at one end of the locking screw near the column;

A movable nut is rotatably installed in the middle of the sleeve, and the movable nut is threadedly connected to the locking screw.

[0016] Preferably, a groove is formed along the axis of the locking screw, and a boss is provided on the sleeve, the boss sliding within the groove.

[0017] Preferably, a support rod is rotatably provided at the end of the locking screw away from the clamping arm. The support rod is L-shaped, and the shorter end of the support rod is rotatably connected to the locking screw. The other end of the support rod is bent upward and rotatably provided with a control handle, which is rotatably connected to the upper end of the clamping arm.

[0018] A pry bar is also rotatably mounted in the middle of the handle, and the pry bar abuts against the support rod.

[0019] The beneficial effects of the technical solution provided by the embodiments of the present invention are as follows: by cooperating with the adjustable positioning mechanism and the fixing mechanism, the in-situ adjustment and precise positioning of the I-beam in the air can be realized, simplifying the operation process that requires multiple hoisting in the traditional process into a single hoisting, shortening the processing time of a single piece, and improving construction efficiency.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] See Figures 1 to 7 The present invention provides a welding fixture for I-beams in green building construction, including a frame 1 that moves on an I-beam A26. The frame 1 includes a vertically arranged column 2, a support frame 3 fixedly arranged at the lower end of the column 2, a traveling wheel 4 for moving on the I-beam on the support frame 3, and a set of fixing mechanisms 5 for fixing the frame 1 to the I-beam on both sides of the support frame 3.

[0033] The frame 1 is also equipped with a positioning mechanism 6, on which a detachable I-beam B27 is connected.

[0034] The user moves the mobile frame 1 along the I-beam A26 until the target welding position. The frame 1 is fixed to the I-beam A26 by the fixing mechanisms 5 on both sides of the support frame 3. The I-beam B27 is connected to the positioning mechanism 6. After the flange of the I-beam B27 has been cut, there will be surface defects in the cut area, which will prevent the web from being embedded into the two flanges. It needs to be ground and repaired. Most of the time, manual grinding is used. After manual grinding, it is spliced. Then it is necessary to judge whether the connection is flush. If the connection is not flush, the I-beam flange needs to be ground again and spliced ​​again. This device only needs to adjust the position of the positioning mechanism 6 to adjust the state of the I-beam B27.

[0035] This device achieves in-situ aerial trimming through the dynamic adjustment of the positioning mechanism 6, reducing the number of hoisting operations to 1, improving work efficiency, and shortening the welding time of the I-beam.

[0036] The positioning mechanism 6 includes two parallel active rods 7, the upper ends of which are rotatably connected to the upper ends of the frame 1, and the lower ends of the two active rods 7 are rotatably connected through a lower connecting rod.

[0037] Each active rod 7 has a driven rod 8 rotatably mounted at its lower end. The movable end of the driven rod 8 is rotatably connected via an adapter frame 9. A connecting unit 10 is fixedly mounted on the adapter frame 9. An I-beam B27 is detachably mounted on the connecting unit 10.

[0038] An adjusting nut 11 is rotatably installed in the middle of an active rod 7 on the side away from the frame 1. The adjusting nut 11 is internally threaded to a lead screw 12, and the lower end of the lead screw 12 is rotatably connected to the frame 1.

[0039] The user fixes the frame 1 on the I-beam A26 and connects the I-beam B27 to the positioning mechanism 6. A handle is fixedly installed at the upper end of the lead screw 12. The user can rotate the lead screw 12 by turning the handle, thereby driving the adjusting nut 11 to move and causing the driving rod 7 to rotate around the upper end of the frame 1.

[0040] Since the driving rod 7, the lower connecting rod, and the driven rod 8 form a parallel four-bar linkage, the adapter 9 remains horizontal. The position of the I-beam B27 is adjusted so that it is far away from the I-beam A26, making it easier for the user to grind and repair the I-beam B27. After grinding and repair, the lead screw 12 is rotated in the opposite direction so that the I-beam B27 is inserted into the upper and lower flanges of the I-beam A26. After confirming that the alignment is correct, temporary spot welding is performed to ensure a stable connection of the I-beams. Finally, the I-beams are fully welded.

[0041] A large gear 13 is fixedly installed at the lower end of one of the drive rods 7 located away from the frame 1, and a small gear 14 is rotatably installed at the lower end of the other drive rod 7. The small gear 14 is fixedly connected to the driven rod 8, and the large gear 13 and the small gear 14 mesh with each other.

[0042] The number of teeth on the large gear 13 is twice the number of teeth on the small gear 14.

[0043] Because the gear ratio is 2:1, the rotation angle of the driven rod 8 is twice that of the driving rod 7. This transmission relationship ensures that the I-beam B27 moves in parallel, so that the horizontal height of the I-beam B27 and the I-beam A26 is always consistent, making it easy for the user to observe the docking situation.

[0044] The connecting unit 10 includes a crossbar 15 fixedly mounted on the adapter frame 9. The two ends of the crossbar 15 are respectively provided with slots, and a clamping block 16 is slidably arranged in each slot. The two clamping blocks 16 are arranged opposite to each other.

[0045] An adjusting screw 17 is also rotatably installed inside the crossbar 15. The two ends of the adjusting screw 17 are respectively threaded, and the two ends of the adjusting screw 17 are respectively threaded to one of the clamping blocks 16.

[0046] Each adjusting screw 17 has a knob fixedly installed at both ends;

[0047] Place the upper flange of the B27 I-beam between two opposing clamping blocks 16, rotate the adjusting screw 17, and drive the two clamping blocks 16 to move synchronously towards each other through the bidirectional thread. Continue to rotate the adjusting screw 17 until the clamping blocks 16 are in close contact with the upper flange of the I-beam. The threaded drive provides a stable clamping force to prevent positional displacement during welding. A single long screw controls the two clamping blocks 16, making clamping and releasing operations simple and quick, and it can be adapted to I-beams of different specifications.

[0048] Moreover, it ensures that the B27 I-beam remains in the center of the adapter frame 9, guaranteeing balanced force during clamping, preventing uneven weighting due to center of gravity shift, and improving the safety of high-altitude operations.

[0049] The fixing mechanism 5 includes a locking screw 18 fixedly mounted on the frame 1, and a clamping arm 19 is rotatably mounted at one end of the locking screw 18 near the column 2;

[0050] A sleeve 20 is fitted onto the locking screw 18, and a locking hook 21 is fixedly installed on the sleeve 20. The locking hook 21 is engaged with the upper flange of the I-beam A26. A movable nut 22 is rotatably installed in the middle of the sleeve 20, and the movable nut 22 is threadedly connected to the locking screw 18.

[0051] Move the frame 1 to the predetermined position of the I-beam A26, ensure that the traveling wheel 4 contacts the flange of the I-beam, rotate the moving nut 22, drive the sleeve 20 to move towards the column 2, so that the locking hook 21 is initially engaged with the upper flange of the I-beam;

[0052] A slot is formed along the axis of the locking screw 18, and a boss is provided on the sleeve 20, which slides in the slot.

[0053] The boss on the sleeve 20 moves linearly along the groove of the locking screw 18 to prevent the sleeve 20 from rotating during use.

[0054] A support rod 23 is rotatably mounted on the end of the locking screw 18 away from the clamping arm 19. The support rod 23 is L-shaped. The shorter end of the support rod 23 is rotatably connected to the locking screw 18. The other end of the support rod 23 is bent upward and rotatably mounted on a control handle 24. The control handle 24 is rotatably connected to the upper end of the clamping arm 19.

[0055] When the operator presses down the control handle 24, the clamping arm 19 is further tightened under the action of the support rod 23. When the rotation axis of the support rod 23 and the locking screw 18, the rotation axis of the support rod 23 and the control handle 24, and the rotation axis of the control handle 24 and the clamping arm 19 are in a straight line, the support rod 23, the control handle 24 and the clamping arm 19 are in the dead point position, and the fixing mechanism 5 can firmly clamp the I-beam A26.

[0056] A pry bar 25 is also rotatably mounted in the middle of the handle, and the pry bar 25 abuts against the support rod 23.

[0057] When it is necessary to unlock this device, press down on the movable end of the pry bar 25. The pry bar 25 pries the control handle 24, breaking the dead point state, releasing the clamp arm 19, and rotating it in the opposite direction to the moving nut 22, causing the sleeve 20 to move outward, and the locking hook 21 to disengage from the I-beam flange, thus completing the unlocking.

[0058] When using this invention, the user moves the mobile frame 1 along the I-beam A26 until the target welding position. The frame 1 is fixed to the I-beam A26 by the fixing mechanisms 5 on both sides of the support frame 3. The I-beam B27 is connected to the positioning mechanism 6. After the flanges of the I-beam B27 have been cut, there will be surface defects in the cut area, which will prevent the web from being embedded into the two flanges. It needs to be ground and repaired. Most of the time, manual grinding is used. After manual grinding, the joint is spliced. Then it is necessary to judge whether the joint is flush. When the joint is not flush, the I-beam flanges need to be ground again and spliced ​​again. This device only needs to adjust the position of the positioning mechanism 6 to adjust the state of the I-beam B27.

[0059] This device achieves in-situ aerial trimming through the dynamic adjustment of the positioning mechanism 6, reducing the number of hoisting operations to 1, improving work efficiency, and shortening the welding time of the I-beam.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
