Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to metal roof structures with built-in ventilation and noise reduction nets, as well as construction equipment and methods. Background Technology

[0002] Metal roofing is a structural enclosure formed by metal sheets, which meets the corresponding functional requirements and provides a suitable internal space environment for the building. Conventional metal roofing does not have requirements for airtightness. In existing technology, conventional standing seam metal roofing is composed of multiple layers of profiled steel sheets.

[0003] In the construction of metal roofing structures, the welding of roof purlins and galvanized square steel pipes is a crucial step. Traditional welding methods rely on manual operation, which is not only inefficient but also carries high risks due to working at heights. During the welding process, it is difficult to ensure a tight, vertical connection between the galvanized square steel pipes and the roof purlins, affecting the weld quality. Furthermore, traditional welding methods require multiple adjustments to the welding equipment position at the four edges of the connection between the roof purlins and the galvanized square steel pipes, making the operation cumbersome and further reducing welding efficiency. Simultaneously, existing welding equipment has limited functionality, is inconvenient to disassemble after welding, hindering equipment storage and relocation, and increasing construction costs and time.

[0004] Therefore, there is an urgent need for a construction equipment that can improve welding efficiency, reduce the risks of high-altitude operations, and is easy to disassemble and store. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing methods, such as difficulty in ensuring a tight vertical connection between galvanized square steel pipes and roof purlins, cumbersome operation of traditional welding methods, low welding efficiency, and inconvenience in storing and moving welding equipment after welding. The invention proposes a metal roof structure with built-in ventilation and noise reduction netting, as well as construction equipment and methods.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The metal roof structure with built-in ventilation and noise reduction netting includes: multiple roof purlins installed on the roof; multiple galvanized square steel pipes welded to the top of the roof purlins; a No. I galvanized steel plate bolted to the top of the roof purlins, the top of which is sequentially covered with waterproof coating and roofing rock wool; multiple Z-shaped steel secondary joists equidistantly fixed to the top of the roofing rock wool; and a No. II galvanized steel plate bolted to the top of the Z-shaped steel secondary joists, the top of which is sequentially covered with waterproof membrane. The structure consists of: a No. III galvanized steel sheet bonded with adhesive; multiple square tubes bolted to the top of the No. III galvanized steel sheet; a ventilation and noise reduction mesh bolted to the top of the square tubes; and a PFW integrated roofing tile installed on top of the ventilation and noise reduction mesh. The top of each galvanized square steel tube sequentially passes through a No. I galvanized steel sheet, waterproof coating, roofing rock wool, a No. II galvanized steel sheet, waterproof membrane, a No. III galvanized steel sheet, and the ventilation and noise reduction mesh. The PFW integrated roofing tile is bolted to the top of the galvanized square steel tube.

[0008] In one possible design, multiple Z-shaped steel frames are equidistantly arranged within the roof rock wool.

[0009] In one possible design, both the No. I galvanized steel sheet and the No. II galvanized steel sheet are provided with multiple punches.

[0010] Construction equipment for automatically welding roof purlins and galvanized square steel pipes in the aforementioned metal roof structure with built-in ventilation and noise reduction netting includes: a U-shaped connecting frame and an L-shaped support frame, which are fitted onto the outer wall of the roof purlins through the insertion and connection of insert plates and slots, and are fixedly connected by screws; a guide U-shaped frame bolted to the top of the U-shaped connecting frame and the L-shaped support frame, which is slidably fitted onto the outer wall of the galvanized square steel pipe; a butt joint structure located inside the guide U-shaped frame, including two rotating rubber wheels and a sliding baffle, wherein the rubber wheels apply downward pressure to the galvanized square steel pipe through friction when rotating; and welding structures for welding the four sides of the butt joint, including welding structure I and welding structure II.

[0011] In one possible design, the inner top wall of the U-shaped connecting frame and the inner top wall of the L-shaped support frame are both rotatably connected to multiple pulleys; a lifting plate is provided on one side of the U-shaped connecting frame, with a No. I threaded rod rotatably connected to its bottom and multiple electric wheels rotatably installed on its top; rotating the No. I threaded rod drives the lifting plate to move upward, so that the electric wheels and pulleys clamp the roof purlins.

[0012] In one possible design, the docking structure further includes: two rotating shafts, each fixing a rubber wheel and extending to the outside of the guide U-shaped frame; a gear fixed to the end of the rotating shaft; a rack slidably disposed on one side of the guide U-shaped frame and meshing with the gear; a connecting plate connecting the two racks; and a threaded rod of type II threaded through the connecting plate; rotating the threaded rod of type II drives the rack to move, and the gear drives the rubber wheel to rotate to apply pressure.

[0013] In one possible design, the No. I welding structure includes: a worm gear rotatably disposed on one side of the U-shaped connecting frame; a movable groove disposed on the top of the U-shaped connecting frame and the L-shaped support frame; a No. III threaded rod rotatably disposed in the movable groove and with a worm wheel fixed at its end, the worm wheel meshing with the worm gear; a movable base threadedly connected to the No. III threaded rod; and a No. I welding torch fixed to the bottom of the movable base; the rotation of the worm gear drives the No. III threaded rod to move and weld the No. I welding torch.

[0014] In one possible design, the No. II welding structure includes: a connecting rod that slides within the strip grooves on both sides of the L-shaped support frame; a No. II welding torch fixed to one end of the connecting rod; a rotating column with threaded rods at both ends fixed to the connecting rod; a limiting rod that slides through the L-shaped support frame and has a limiting groove at its bottom to restrict the movement of the connecting rod; after the rotating column rotates to adjust the distance between the connecting rods, the limiting rod and the limiting groove cooperate to allow the No. II welding torch to move linearly for welding.

[0015] In one possible design, it also includes a No. IV threaded rod rotatably connected to one side of the L-shaped support frame; a nut seat threaded onto the outer wall of the No. IV threaded rod; a connecting rod rotatably connecting the nut seat and the rotating column; and a retaining seat fixed to one side of the L-shaped support frame; the No. IV threaded rod rotates to drive the nut seat to move, and the connecting rod pulls the rotating column into the retaining seat for storage.

[0016] The construction method for the construction equipment in this application includes the following steps:

[0017] S1. Equipment Installation: Fit the U-shaped connecting frame onto the roof purlin, insert the insert plate into the slot, and fix the U-shaped connecting frame and L-shaped support frame with screws. The worm gear passes through the limit seat. Fix the guide U-shaped frame to the top of the U-shaped connecting frame and L-shaped support frame with bolts. The positioning block abuts against both sides of the roof purlin to center it.

[0018] S2. Equipment lifting and moving: Rotate threaded rod I to drive the lifting plate to move upward, so that the electric wheel and pulley cooperate to install the equipment on the roof purlin; run the electric wheel to move the equipment to the welding position;

[0019] S3. Square tube positioning: Insert the galvanized square steel tube into the guide U-shaped frame, with the bottom end abutting the top of the roof purlin, making it vertical;

[0020] S4. Square tube clamping: Rotate the No. II threaded rod to drive the connecting plate and rack to move down. The rack meshes with the gear to drive the rubber wheel to rotate. The two rubber wheels press against the galvanized square steel tube to make it tightly connected to the roof purlin.

[0021] S5, No. 1 welding: The motor drives the worm gear to rotate, the worm gear drives the worm wheel and No. 3 threaded rod to rotate, which drives the moving base and No. 1 welding gun to move and weld the two adjacent sides;

[0022] S6, No. 2 welding: The motor drives No. 4 threaded rod to rotate, which causes the nut seat to move down. The nut seat pulls the rotating column through the connecting rod. The rotating column drives the connecting rod and No. 2 welding gun through the screw to move and weld the remaining two sides.

[0023] S7. Workstation Transfer: Remove the baffle inside the guide U-shaped frame; move the electric wheeled equipment to the new welding position;

[0024] S8. Repeat welding: Repeat steps S3 to S6 at the new location;

[0025] S9. Equipment disassembly: Remove the limit rod; rotate the rotating column to drive the screw to rotate and disconnect it from the connecting rod, and remove the connecting rod; rotate the rotating column to engage the mounting bracket; disassemble the U-shaped connecting frame, L-shaped support frame and guide U-shaped frame.

[0026] Beneficial effects: In this invention, a baffle slides inside the guide U-shaped frame, and a rotating shaft is rotatably connected to each of the two rectangular holes. A rubber wheel is fixedly sleeved on the outer wall of the rotating shaft, and a gear is fixed to one end of each of the two rotating shafts. Two racks are slidably connected to one side of the guide U-shaped frame. Through the cooperation of the U-shaped connecting frame, the L-shaped support frame, and the guide U-shaped frame, the galvanized square steel pipe can be made perpendicular to the top of the roof purlin. Rotating the No. II threaded rod drives the connecting plate and the rack to move down. The rack and gear cooperate to drive the rubber wheel to rotate. Since the two rubber wheels abut against the two sides of the galvanized square steel pipe, the friction between the rubber wheels and the galvanized square steel pipe applies downward pressure to the galvanized square steel pipe. Thus, the galvanized square steel pipe can be tightly connected to the roof purlin without manual operation, which is convenient for subsequent welding operations.

[0027] In this invention, a worm gear rotates on one side of the U-shaped connecting frame, and a No. III threaded rod is rotatably connected in each of the two moving slots. A moving base, threadedly connected to the corresponding No. III threaded rod, is slidably connected in each of the two moving slots. A No. I welding torch is fixed to the bottom of each of the two moving bases, and a worm wheel is fixed to one end of each of the two No. III threaded rods. The worm gear is driven to rotate by a motor, and the worm gear synchronously drives the two worm wheels and the No. III threaded rod to rotate. The No. III threaded rod drives the moving base to move, and the No. I welding torch welds two sides of the connection between the roof purlin and the galvanized square steel pipe. The operation is simple, which not only improves welding efficiency but also reduces the risk of working at height.

[0028] In this invention, connecting rods are slidably fitted within both of the two strip grooves, and a No. II welding gun is fixed to one end of each of the two connecting rods. Two limiting rods slide through the L-shaped support frame, and limiting grooves are provided at the bottom of each of the two limiting rods. A rotating column is provided on one side of the L-shaped support frame, and screws are fixed to both ends of the rotating column. The two screws are threaded through the corresponding connecting rods. The distance between the two connecting rods is limited by the rotation of the rotating column and the screws, which facilitates the cooperation between the limiting rods and the connecting rods. Subsequently, the rotating column drives the connecting rods to move back and forth to weld the roof purlins and galvanized square steel pipes, easily completing the welding operation.

[0029] In this invention, a No. IV threaded rod is rotatably connected to one side of the L-shaped support frame. A nut seat is threaded onto the outer wall of the No. IV threaded rod. A connecting rod is rotatably connected to one side of the nut seat. The connecting rod is rotatably connected to the rotating column. Two clamps are fixed to one side of the L-shaped support frame, and the clamps engage with the rotating column. The No. IV threaded rod is driven to rotate by a motor. The No. IV threaded rod drives the nut seat to move downward. The nut seat pulls the rotating column toward the L-shaped support frame through the connecting rod. Thus, the No. II welding torch can automatically weld the other two sides of the connection between the roof purlin and the galvanized square steel pipe, improving welding efficiency and reducing the risk of high-altitude operations. In addition, the connecting rod can be disassembled and the rotating column can be stored, making it easy to move the equipment.

[0030] In this invention, by optimizing the layout and connection method of each layer of materials, excellent sound insulation, ventilation and waterproof performance are achieved. At the same time, the construction equipment simplifies the construction process and improves the welding quality through automated and precise welding operations. This metal roof structure and its construction equipment have broad application prospects and are particularly suitable for building fields with high requirements for sound insulation, ventilation and waterproof performance.

[0043] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0044] In one embodiment: Refer to Figure 1 and Figure 2 The roof structure, which relates to the field of building construction technology, achieves good sound insulation, ventilation and waterproofing performance by optimizing the layout and connection of materials in each layer.

[0045] Reference Figure 1 The roof purlin 1 serves as the basic supporting component of the roof structure, and multiple galvanized square steel pipes 2 are welded to its top. The specifications of the galvanized square steel pipes 2 are selected according to actual needs, generally with a length between 1 and 3 meters and a cross-sectional size between 50mm×50mm and 100mm×100mm. During welding, ensure that the galvanized square steel pipes 2 are perpendicular to the top of the roof purlin 1 to guarantee the stability of the subsequent structure.

[0046] Reference Figure 1 At the top of the roof purlin 1, a No. I galvanized steel sheet 3 is fixed with bolts. The thickness of the No. I galvanized steel sheet 3 is generally between 0.5 and 1.5 mm, and it has multiple perforations to increase ventilation. The top of the No. I galvanized steel sheet 3 is coated with a waterproof coating 4, which is between 1 and 2 mm thick, to ensure the waterproof performance of the roof structure.

[0047] Reference Figure 1 On top of the waterproof coating 4, roofing rock wool 5 is laid. The thickness of the roofing rock wool 5 is generally between 100 and 150 mm, and multiple Z-shaped steel frames 6 are evenly distributed inside it. The specifications of the Z-shaped steel frames 6 are selected according to actual needs to enhance the supporting performance of the roofing rock wool 5.

[0048] Reference Figure 1 and Figure 2 On top of the roof rock wool 5, multiple Z-shaped steel secondary joists 7 are fixed at equal intervals. The specifications of the Z-shaped steel secondary joists 7 are similar to those of the Z-shaped steel frame 6, but the size may be slightly smaller to accommodate different installation requirements. A No. II galvanized steel plate 8 is bolted to the top of the Z-shaped steel secondary joists 7. The thickness of the No. II galvanized steel plate 8 is similar to that of the No. I galvanized steel plate 3, and it also has multiple perforations to increase ventilation.

[0049] Reference Figure 1 A waterproof membrane 9 is laid on top of the No. II galvanized steel sheet 8. The thickness of the waterproof membrane 9 is generally between 1 and 2 mm, and its material has good waterproof performance. A No. III galvanized steel sheet 10 is glued to the top of the waterproof membrane 9. The thickness of the No. III galvanized steel sheet 10 is similar to that of the No. I and No. II galvanized steel sheets, and multiple square tubes 11 are bolted to its top. The specifications of the square tubes 11 are selected according to actual needs and are used to press the No. III galvanized steel sheet 10 to increase its stability.

[0050] Reference Figure 1Ventilation and noise reduction mesh 12 is bolted to the top of multiple square tubes 11. The ventilation and noise reduction mesh 12 is typically made of metal or plastic, with a mesh size between 5 and 10 millimeters to achieve good ventilation and noise reduction. A PFW integrated roofing tile 13 is installed on top of the ventilation and noise reduction mesh 12. The specifications of the PFW integrated roofing tile 13 are selected according to actual needs, and it is bolted to the top of the galvanized square steel tubes 2 to ensure the stability of the entire roof structure.

[0051] Reference Figures 3-11 Construction equipment is used for the automatic welding of roof purlins 1 and galvanized square steel pipes 2 in the aforementioned metal roof structure with built-in ventilation and noise reduction nets. The equipment includes a U-shaped connecting frame 14, an L-shaped support frame 15, and a guide U-shaped frame 25. The U-shaped connecting frame 14 and the L-shaped support frame 15 are connected by an assembly structure. The assembly structure includes a slot 16 on one side of the U-shaped connecting frame 14 and an insert plate 17 that slides within the slot 16 and is fixedly connected to the L-shaped support frame 15. The width of the insert plate 17 matches the width of the slot 16, and the length of the insert plate 17 is slightly greater than the depth of the slot 16 to ensure connection stability. Furthermore, the U-shaped connecting frame 14 and the L-shaped support frame 15 are equipped with multiple screws 18, one end of which extends into the U-shaped connecting frame 14 and is threadedly connected to it, for fixing the U-shaped connecting frame 14 to the L-shaped support frame 15.

[0052] Reference Figures 4-6 Multiple pulleys 19 are rotatably connected to the top inner wall of the U-shaped connecting frame 14 and the top inner wall of the L-shaped support frame 15, with the pulleys 19 located at the top of the roof purlin 1. A square groove 20 is provided on the top of one side of the U-shaped connecting frame 14, and a lifting plate 21 is slidably connected within the square groove 20. Multiple guide rods 24 are fixed to the bottom of the lifting plate 21, and the bottom ends of the guide rods 24 all slide to the bottom of the U-shaped connecting frame 14. A threaded rod 23 of No. I is rotatably connected to the bottom of the lifting plate 21, and the bottom end of the threaded rod 23 of No. I threaded rod 23 passes through the U-shaped connecting frame 14. Multiple electric wheels 22 are rotatably provided on the top of the lifting plate 21, with the electric wheels 22 located at the bottom of the roof purlin 1. By rotating the threaded rod 23 of No. I, the lifting plate 21 can be driven to move upward, so that the electric wheels 22 cooperate with the pulleys 19 to clamp the roof purlin 1, and so that the U-shaped connecting frame 14 and the L-shaped support frame 15 can move smoothly on the roof purlin 1.

[0053] Reference Figure 3 and Figure 4The guide U-shaped frame 25 is bolted to the top of the U-shaped connecting frame 14 and the L-shaped support frame 15. The guide U-shaped frame 25 is available in various sizes to accommodate galvanized square steel pipes 2 of different dimensions. The internal width of the guide U-shaped frame 25 is slightly larger than the width of the galvanized square steel pipe 2 to ensure smooth insertion. The guide U-shaped frame 25 also includes a butt joint structure to allow the galvanized square steel pipe 2 to be placed vertically on top of the roof purlin 1, facilitating subsequent vertical welding of the roof purlin 1 and the galvanized square steel pipe 2.

[0054] Reference Figure 3 , Figure 7 and Figure 8 The docking structure includes two rubber wheels 29 rotating within a guide U-shaped frame 25 and a baffle 26 sliding within the guide U-shaped frame 25 to limit the galvanized square steel pipe 2. The diameter of the rubber wheels 29 is between 50 and 80 mm, and their material has good wear resistance and elasticity. Multiple sliders are fixed on both sides of the baffle 26. Multiple sliding grooves are provided on the inner walls of the guide U-shaped frame 25 on both sides away from each other. The sliders slide in the sliding grooves to limit the galvanized square steel pipe 2 and facilitate the disassembly of the baffle 26 later. Rectangular holes 27 are provided on both sides of the guide U-shaped frame 25 away from each other. Rotating shafts 28 are rotatably connected to both rectangular holes 27, and the two rubber wheels 29 are respectively fixed to the outer walls of the two rotating shafts 28. One end of each of the two rotating shafts 28 extends rotatably to one side of the guide U-shaped frame 25 and is fixed with a gear 30. Two racks 32 are slidably connected to one side of the guide U-shaped frame 25, and the racks 32 mesh with the corresponding gears 30. A connecting plate 31 is fixed between the two racks 32, and the connecting plate 31 slides on one side of the guide U-shaped frame 25. A No. II threaded rod 33 is rotatably connected to one side of the guide U-shaped frame 25 via a base plate, and the No. II threaded rod 33 is threaded through the connecting plate 31. By rotating the No. II threaded rod 33, the connecting plate 31 and the racks 32 can be driven to move downward, thereby driving the rubber wheel 29 to rotate, applying downward pressure to the galvanized square steel pipe 2, so that it is tightly connected to the roof purlin 1.

[0055] Reference Figures 3-5 and Figure 9The No. I welding structure includes a worm gear 39 that rotates on one side of the U-shaped connecting frame 14 via a base. A limit seat 40 is fixed to one side of the L-shaped support frame 15, and one end of the worm gear 39 passes through the limit seat 40 to support the worm gear 39. The top inner walls of both the U-shaped connecting frame 14 and the L-shaped support frame 15 are provided with moving grooves 34, and each of the two moving grooves 34 is rotatably connected to a No. III threaded rod 35. Each of the two moving grooves 34 is slidably connected to a moving base 36 that is threaded to the corresponding No. III threaded rod 35. A No. I welding torch 37 is fixed to the bottom of each of the two moving bases 36 for welding two opposite sides of the connection between the roof purlin 1 and the galvanized square steel pipe 2. One end of each of the two No. III threaded rods 35 extends to one side of the U-shaped connecting frame 14 and the L-shaped support frame 15, and each is fixed with a worm wheel 38, which meshes with the worm gear 39. The worm gear 39 is driven by a motor to rotate, which in turn drives the two worm wheels 38 and the No. III threaded rod 35 to rotate, thereby moving the movable base 36 so that the No. I welding gun 37 can weld two sides of the connection between the roof purlin 1 and the galvanized square steel pipe 2.

[0056] Reference Figure 3 , Figure 4 , Figure 10 and Figure 11 The No. II welding structure includes two strip grooves 41 on both sides of the L-shaped support frame 15. Connecting rods 42 are slidably fitted within each of the two strip grooves 41, and a No. II welding torch 43 is fixed to one end of each connecting rod 42. The two No. II welding torches 43 are used to weld the other two opposite edges at the connection between the roof purlin 1 and the galvanized square steel pipe 2. Two limiting rods 50 slide through the L-shaped support frame 15, and each limiting rod 50 has a limiting groove 51 at its bottom. The connecting rod 42 slides through the limiting groove 51. The limiting groove 51 cooperates with the strip groove 41 to limit the connecting rod 42, allowing it to move linearly. A rotating column 44 is provided on one side of the L-shaped support frame 15, and screws 45 are fixed to both ends of the rotating column 44. The two screws 45 are threaded through the corresponding connecting rods 42. By rotating the rotating column 44 and the screw 45, the distance between the two connecting rods 42 can be limited, which facilitates the cooperation between the limiting rod 50 and the connecting rod 42.

[0057] In another embodiment, refer to Figure 10 and Figure 11The L-shaped support frame 15, away from the U-shaped connecting frame 14, is rotatably connected to a threaded rod 46 (No. IV) via a base. A nut seat 47, which is slidably connected to the L-shaped support frame 15, is threaded onto the outer wall of the threaded rod 46. A connecting rod 48 is rotatably connected to one side of the nut seat 47, and the top of the connecting rod 48 is rotatably connected to a rotating column 44. Driving the threaded rod 46 via a motor causes the nut seat 47 to move downwards, which in turn pulls the rotating column 44 towards the L-shaped support frame 15 via the connecting rod 48. The rotating column 44, via a screw 45, moves the connecting rod 42 and the welding torch 43 (No. II) towards the center, allowing the welding torch 43 to weld the other two sides of the connection between the roof purlin 1 and the galvanized square steel pipe 2.

[0058] After welding is completed, the limiting rod 50 is removed from the L-shaped support frame 15, releasing the limiting effect on the connecting rod 42. Rotating the rotating column 44 drives the screw 45 to rotate, disengaging the connecting rod 42 from the slot 41, thus disassembling the connecting rod 42 from the L-shaped support frame 15. The rotating column 44 rotates and then engages with the retaining seat 49, limiting its position. Afterwards, the U-shaped connecting frame 14, L-shaped support frame 15, and guide U-shaped frame 25 are disassembled, allowing the equipment to be stored and moved.

[0059] The construction method for the construction equipment includes the following steps:

[0060] S1. Place the U-shaped connecting bracket 14 onto the roof purlin 1, insert the insert plate 17 into the slot 16, and fix the U-shaped connecting bracket 14 and the L-shaped support bracket 15 with screws 18. During connection, one end of the worm gear 39 passes through the limiting seat 40 to support the worm gear 39. Then, fix the guide U-shaped bracket 25 to the top of the U-shaped connecting bracket 14 and the L-shaped support bracket 15 with bolts. The initial installation is completed. In addition, the positioning blocks 52 on the U-shaped connecting bracket 14 and the L-shaped support bracket 15 respectively abut against the roof purlin 1. The two sides of the roof purlin 1 are used to position the roof purlin 1 at the center of the U-shaped connecting frame 14 and the L-shaped support frame 15. Then, the No. I threaded rod 23 is rotated to drive the lifting plate 21 to move upward. The electric wheel 22 cooperates with the pulley 19 in the U-shaped connecting frame 14 and the L-shaped support frame 15 to install the U-shaped connecting frame 14 and the L-shaped support frame 15 on the roof purlin 1. Then, the operation of the electric wheel 22 drives the U-shaped connecting frame 14 and the L-shaped support frame 15 to move to the designated position, which facilitates the subsequent welding of the roof purlin 1 and the galvanized square steel pipe 2.

[0061] S2. Next, insert the galvanized square steel pipe 2 into the guide U-shaped frame 25, with its bottom end abutting against the top of the roof purlin 1. Through the cooperation of the U-shaped connecting frame 14, the L-shaped support frame 15 and the guide U-shaped frame 25, the galvanized square steel pipe 2 can be made perpendicular to the top of the roof purlin 1. In order to facilitate the vertical welding of the roof purlin 1 and the galvanized square steel pipe 2 later, rotate the No. II threaded rod 33 to drive the connecting plate 31 and the rack 32 to move down. The rack 32 cooperates with the gear 30 to drive the rubber wheel 29 to rotate. Since the two rubber wheels 29 abut against the two sides of the galvanized square steel pipe 2, the friction between the rubber wheels 29 and the galvanized square steel pipe 2 applies downward pressure to the galvanized square steel pipe 2. Thus, the galvanized square steel pipe 2 can be tightly connected to the roof purlin 1 without manual operation.

[0062] S3. During welding, the worm gear 39 is driven to rotate by the motor. The worm gear 39 synchronously drives the two worm wheels 38 and the No. III threaded rod 35 to rotate. The No. III threaded rod 35 drives the moving base 36 to move. The No. I welding gun 37 welds two sides of the connection between the roof purlin 1 and the galvanized square steel pipe 2. Then, the No. IV threaded rod 46 is driven to rotate by the motor. The No. IV threaded rod 46 drives the nut seat 47 to move down. The nut seat 47 pulls the rotating column 44 towards the L-shaped support frame 15 through the connecting rod 48. The rotating column 44 drives the connecting rod 42 and the No. II welding gun 43 to move towards the middle through the screw 45. Then, the No. II welding gun 43 can weld the other two sides of the connection between the roof purlin 1 and the galvanized square steel pipe 2, thus easily completing the welding operation of the roof purlin 1 and the galvanized square steel pipe 2.

[0063] S4. When welding is required at other locations on the roof purlin 1, pull the baffle 26 upward from the guide U-shaped frame 25 to release the restriction on the galvanized square steel pipe 2. Then, the electric wheel 22 drives the U-shaped connecting frame 14, the L-shaped support frame 15, and the guide U-shaped frame 25 to the designated position. Repeat the operation to complete the welding of the roof purlin 1 and the galvanized square steel pipe 2, improving welding efficiency and reducing the risk of workers working at height. After the welding operation is completed, move the limit rod 50 from the L-shaped support frame 25 to the guide U-shaped frame 25. Remove the U-shaped support frame 15, release the limiting position on the connecting rod 42, rotate the rotating column 44 to drive the screw 45 to rotate, the screw 45 to release the connection to the connecting rod 42, and the connecting rod 42 to move out of the strip groove 41, completing the disassembly of the connecting rod 42 from the L-shaped support frame 15. The rotating column 44 rotates and then gets into the card seat 49, limiting the rotation column 44. Then, the U-shaped connecting frame 14, the L-shaped support frame 15 and the guide U-shaped frame 25 are disassembled, so that the equipment can be stored and moved.
