Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to an auxiliary installation component for an ultra-long cantilevered steel structure pitched roof. Background Technology

[0002] In recent years, with the development of urban construction, the appearance of buildings has continued to evolve, and the design of roof decorations has become increasingly diversified. Among them, cantilevered pitched roofs are quite common, and they are often combined with lighting strips to make them aesthetically pleasing. However, the construction of cantilevered pitched roofs has become one of the major challenges in engineering construction.

[0003] In the existing technology, the construction of cantilevered pitched roofs generally requires the assembly and welding of various steel frames, steel rods and other parts. Since the welding position or the installation position of steel frames, steel rods and steel beams is sometimes high, workers need to bring ladders close to the wall and complete the welding operation with the cooperation of several workers. At the same time, when installing metal roof panels, it is often necessary to connect the metal roof panels and steel plates with aluminum alloy fixing supports in the middle, and the metal roof panels are fixed in sections with aluminum alloy clamps.

[0004] However, the welding and fixing installation work requires several workers to stabilize the ladder and several workers to perform the welding work, which wastes human resources and reduces construction efficiency. At the same time, the metal roof panel is connected to the steel plate with aluminum alloy fixing brackets, and the metal roof panel is fixed in sections with aluminum alloy clamps. This installation method is cumbersome and inconvenient to disassemble and install, thus reducing practicality. To address these issues, this invention proposes an auxiliary installation component for ultra-long cantilever steel structure pitched roofs. Summary of the Invention

[0013] Preferably, the pre-embedded steel plate is embedded in the main structure truss beam. The upper steel tie rod is welded and fixed to the pre-embedded steel plate, the main structure parapet wall, and the main structure column. A lower steel tie rod is provided on the lower side of the upper steel tie rod. One end of the lower steel tie rod is welded and fixed to the main structure truss beam and the main structure parapet wall, and the other end of the lower steel tie rod is welded and fixed to the bottom of the upper steel tie rod.

[0014] Preferably, one side of the fixed square tube is welded and fixed to the upper steel tie rod, and the other side of the fixed square tube is welded and fixed to the galvanized steel plate. A bent steel plate is provided on one side of the galvanized steel plate, and a water guide groove is welded and fixed on the other side of the galvanized steel plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. By moving the support plate to the bottom of the parapet wall of the main structure, the adjusting rod is rotated by turning the handle. The adjusting rod then drives the worm gear installed in the support base to rotate. The worm gear meshes with the worm wheel, and the rotation of the worm wheel drives the rotating shaft to rotate. Sleeves are fixedly fitted on both sides of the rotating shaft, so the rotating shaft drives the sleeves to rotate within the support frame. The sleeves then drive the short rod to rotate. One end of the short rod pushes the long rod to move through the connecting shaft. Thus, the long rod is rotated and connected to the fixed column, allowing the ladder frame to move away from the support frame under the rotational cooperation of the fixed rod and the roller. At the same time, the two sides of the ladder frame are stabilized during the movement by the rotational cooperation between the limiting rod installed on the fixed base, the fixed column, and the rotating rod. Finally, the upper edge of the ladder frame abuts against the upper surface of the support platform, completing the deployment of the ladder frame. This facilitates operation on the ladder frame, avoids the need for multiple operators to work together, simplifies operation, avoids waste of human resources, and improves construction efficiency.

[0019] 2. By fitting one end of the limiting screw into the mounting hole and passing through the metal roof panel, galvanized steel plate, and fixed square tube, and with the other end of the limiting screw abutting against the upper surface of the metal roof panel, the fastening sleeve is twisted. Due to the threaded engagement between the fastening sleeve and the fixing shell, the fastening sleeve will continuously descend within the fixing shell. Then, the forks at the upper end of the fastening clamp, which have tapered surfaces, engage with the inner tapered surface at the bottom of the fastening sleeve to continuously tighten, thereby clamping the limiting screw. Finally, a nut is threadedly connected to one end of the limiting screw, thus fixing the metal roof panel onto the galvanized steel plate under the tightening and limiting action of the limiting screw. This simplifies the installation and disassembly process of the metal roof panel, improves the efficiency of installation and disassembly, and enhances the overall practicality.

Furthermore, all embodiments can be used in combination with each other.

[0032] Please see Figures 1 to 7 This invention provides a technical solution: an auxiliary installation component for an ultra-long cantilevered steel structure pitched roof, comprising:

[0033] The auxiliary installation component body 1 has a support plate 2 at its bottom, a support platform 3 on its upper side, an adjusting rod 4 on one side of the support platform 3, a ladder 5 on one side of the adjusting rod 4, a support frame 16 fixedly connected to the upper surface of the support plate 2, and the upper surface of the support frame 16 fixedly connected to the support platform 3. Four support frames 16 are provided and equidistantly arranged about the lower surface of the support platform 3. A fixed seat 17 is fixedly installed at the bottom of one side of the support frame 16, and a support base 18 is fixedly connected to the top of one side of the support frame 16. A worm gear 19 is fitted inside the support base 18, and the worm gear 19 is rotatably connected to the support base 18. One end of the worm gear 19 is fixedly connected to the adjusting rod 4. A handle 20 is fixedly fitted at one end of the adjusting rod 4. A worm wheel 21 meshes with one side of the worm gear 19, and a rotating shaft 22 is fitted inside the worm wheel 21. The rotating shaft 22 and the worm wheel... The ladder frame 5 is fixedly connected to the support frame 16 on both sides. The support frame 16 is fixedly fitted with sleeves 23 on one side and is rotatably connected to the support frame 16 on the other side. A short rod 24 is fixedly connected to the other side of the sleeve 23. A long rod 25 is provided on the lower side of the short rod 24. Fixed columns 26 are fixedly connected to both sides of the ladder frame 5. One end of the long rod 25 is rotatably connected to the short rod 24 through a connecting shaft 27. The other end of the long rod 25 is fitted on the fixed column 26 and is rotatably connected to the fixed column 26. A limiting rod 28 is fixedly fitted to one side of the fixed seat 17. The limiting rod 28 is rotatably connected to the fixed column 26 through a rotating rod 29. A roller 30 is provided at the bottom of the ladder frame 5. A fixed rod 31 is fitted inside the roller 30 and is rotatably connected to the fixed rod 31. The two ends of the fixed rod 31 are fixedly connected to the fixed column 26.

[0034] The support plate 2 facilitates the transfer of the ladder frame 5, thereby enabling installation and welding at different locations on the ultra-long cantilevered steel structure sloping roof. The support frame 16 provides fixed support for the support platform 3, thereby improving the stability of the ladder frame 5. When work needs to be performed on the ladder frame 5, the support plate 2 is moved to the bottom of the parapet wall 7 of the main structure. By turning the handle 20, the adjusting rod 4 is rotated, which in turn drives the worm gear 19 installed in the support base 18 to rotate. The worm gear 19 meshes with the worm wheel 21, and the rotation of the worm wheel 21 causes the worm wheel 21 to drive the rotating shaft 22 to rotate. Sleeves 23 are fixedly sleeved on both sides of the rotating shaft 22, so the rotating shaft 22 drives the sleeves 23 to rotate within the support frame 16, and the sleeves 23 drive the shaft 22 to rotate. The short rod 24 rotates, and one end of the short rod 24 pushes the long rod 25 to move through the connecting shaft 27. Thus, the long rod 25 is rotated and connected to the fixed column 26, causing the ladder frame 5 to move away from the support frame 16 under the rotational cooperation of the fixed rod 31 and the roller 30. At the same time, the two sides of the ladder frame 5 are rotated and cooperated with the fixed column 26 and the rotating rod 29 through the limiting rod 28 installed on the fixed seat 17, so that the ladder frame 5 is more stable during the movement. Finally, the upper edge of the ladder frame 5 abuts against the upper surface of the support platform 3, completing the unfolding of the ladder frame 5. This makes it easier for operators to work on the ladder frame 5, avoids the need for multiple operators to work together, simplifies the operation, avoids the waste of human resources, and improves construction efficiency.

[0035] A main structural column 6 is installed on one side of the ladder frame 5. A main structural parapet wall 7 is fixedly connected to one side of the main structural column 6. A main structural pergola beam 8 is installed on the upper side of the main structural parapet wall 7. An upper steel tie rod 9 is fixedly connected to one side of the main structural pergola beam 8. A fixed square tube 10 is installed on the upper side of the upper steel tie rod 9. A pre-embedded steel plate 15 is embedded in the main structural pergola beam 8. The upper steel tie rod 9 is welded and fixed to the pre-embedded steel plate 15, the main structural parapet wall 7, and the main structural column 6. A lower steel tie rod 32 is installed on the lower side of the upper steel tie rod 9. One end of the lower steel tie rod 32 is welded and fixed to the main structural pergola beam 8 and the main structural parapet wall 7. The other end of the lower steel tie rod 32 is welded and fixed to the bottom of the upper steel tie rod 9. One side of the fixed square tube 10 is welded and fixed to the upper steel tie rod 9. The other side of the fixed square tube 10 is welded and fixed to the galvanized steel plate 10. 1. Welding and fixing: A bent steel plate 14 is provided on one side of the galvanized steel plate 11. A water guide channel 33 is welded and fixed on the other side of the galvanized steel plate 11. One side of the bent steel plate 14 is welded and fixed to the embedded steel plate 15. The other side of the bent steel plate 14 is fixedly connected to the galvanized steel plate 11 by self-tapping screws 34. A connecting plate 35 is provided on one side of the outer aluminum single panel 13. The connecting plate 35 is fixedly connected to the outer aluminum single panel 13 by high-strength bolts 36. A longitudinal steel frame beam 37 is provided on one side of the connecting plate 35. One side of the longitudinal steel frame beam 37 is welded and fixed to the embedded steel plate 15. The other side of the longitudinal steel frame beam 37 is fixedly connected to the connecting plate 35 by self-tapping screws 34. Steel bars 38 are fixedly welded to the bottom of the upper steel tie rod 9, the lower steel tie rod 32, and the water guide channel 33. One end of the steel bar 38 is welded and fixed to the main structure flower rack beam 8.

[0036] The connection of the steel plate 15 embedded in the main structural pergola beam 8 avoids the risks of insufficient positioning accuracy and leakage associated with pre-embedded bolt connections. The upper steel tie rod 9 is welded and fixed to the embedded steel plate 15, the main structural parapet wall 7, and the main structural column 6. The lower steel tie rod 32 is also welded and fixed to the upper steel tie rod 9, the main structural pergola beam 8, and the main structural parapet wall 7, thereby increasing the overall structural stability. The fixed square tube 10 is used for connection and fixing. The fixed square tube 10 is welded and installed between the upper steel tie rod 9 and the galvanized steel plate 11, thus supporting the metal roof panel 12 and facilitating its installation. The galvanized steel plate 11 and the bent steel plate 14 are connected by self-tapping screws 34. A water guide channel 33 is welded and fixed on one side of the galvanized steel plate 11 and the other side. The water guide channel 33 is used to divert water and prevent water from pooling on the cantilevered steel structure sloping roof. The steel strip 38 further stabilizes the bottom of the upper steel tie rod 9, the lower steel tie rod 32, and the water guide channel 33. The outer aluminum single panel 13 and the connecting plate 35 are connected by M20 high-strength bolts 36. The connecting plate 35 and the longitudinal steel frame beam 37 are connected by self-tapping screws 34. The galvanized steel plate 11 and the bent steel plate 14 are connected by self-tapping screws 34. The bent steel plate 14 and the main structure truss beam 8 are connected by welding.

[0037] A galvanized steel plate 11 is installed on the upper side of the fixed square tube 10. A metal roof panel 12 is installed on the upper side of the galvanized steel plate 11. An outer aluminum single panel 13 is installed on the upper side of the metal roof panel 12. A bent steel plate 14 is installed on the lower side of the outer aluminum single panel 13. A pre-embedded steel plate 15 is installed on one side of the bent steel plate 14. An installation hole 39 is opened on the upper surface of the metal roof panel 12 and the installation hole 39 passes through the fixed square tube 10. A fixed shell 40 is fixedly sleeved inside the fixed square tube 10. A fastening clip 41 is fixedly snapped at the bottom of the fixed shell 40. A fastening sleeve 42 is threadedly connected to the top of the fixed shell 40. A limiting screw 43 is sleeved inside the fastening clip 41. One end of the limiting screw 43 abuts against the surface of the metal roof panel 12. The other end of the limiting screw 43 is threadedly connected to a nut 44.

[0038] When installing the metal roof panel 12, place it on the upper surface of the galvanized steel sheet 11. Insert one end of the limiting screw 43 into the mounting hole 39, passing through the metal roof panel 12, the galvanized steel sheet 11, and the fixing square tube 10. The other end of the limiting screw 43 abuts against the upper surface of the metal roof panel 12. Then, twist the fastening sleeve 42. Due to the threaded fit between the fastening sleeve 42 and the fixing shell 40, the fastening sleeve 42 will continuously descend within the fixing shell 40. The forks at the upper end of the fastening clamp 41 are all tapered, and their tapered surfaces cooperate with the inner tapered surface at the bottom of the fastening sleeve 42 to continuously tighten, thereby clamping the limiting screw 43. Finally, the nut 44 is threadedly connected to one end of the limiting screw 43, and the metal roof panel 12 is fixedly installed on the galvanized steel plate 11 under the tightening and limiting action of the limiting screw 43. This simplifies the installation and disassembly process of the metal roof panel 12, improves the efficiency of disassembly and assembly, and enhances the overall practicality.

[0039] In actual use, when work needs to be carried out on the ladder frame 5, the support plate 2 is moved to the bottom of the parapet wall 7 of the main structure. By turning the handle 20, the adjusting rod 4 is rotated, which in turn drives the worm gear 19 installed in the support base 18 to rotate. The worm gear 19 meshes with the worm wheel 21, and the rotation of the worm wheel 21 causes the worm wheel 21 to drive the rotating shaft 22 to rotate. Sleeves 23 are fixedly sleeved on both sides of the rotating shaft 22, so the rotating shaft 22 drives the sleeves 23 to rotate in the support frame 16. The sleeves 23 then drive the short rod 24 to rotate. One end of the short rod 24 pushes the long rod 25 to move through the connecting shaft 27, so that one end of the long rod 25 is rotated and connected to the fixed column 26. This causes the ladder frame 5 to move away from the support frame 16 under the rotational cooperation of the fixed rod 31 and the roller 30. The ladder frame 5 moves in the direction of movement, and at the same time, the two sides of the ladder frame 5 are rotated through the limiting rod 28 installed on the fixed seat 17 and the fixed column 26 and rotating rod 29, so that the ladder frame 5 is more stable during movement, until the upper edge of the ladder frame 5 abuts against the upper surface of the support platform 3, completing the unfolding of the ladder frame 5. This makes it easier for operators to work on the ladder frame 5, and avoids the need for multiple operators to work together. The operation is simple, avoids the waste of human resources, and improves construction efficiency. The connection of the steel plate 15 embedded in the main structure truss beam 8 avoids the risk of insufficient positioning accuracy and leakage of the pre-embedded bolt connection. The upper steel tie rod 9 is welded and fixed to the pre-embedded steel plate 15, the main structure parapet wall 7, and the main structure column 6. The lower steel tie rod 32 is connected to the upper steel tie rod 9 and the main structure. The truss beam 8 and the main structure parapet wall 7 are welded and fixed together to increase the overall structural stability. The fixed square tube 10 is used for connection and fixing. The fixed square tube 10 is welded and installed between the upper steel tie rod 9 and the galvanized steel plate 11, thus supporting the metal roof panel 12 and facilitating its installation. The galvanized steel plate 11 and the bent steel plate 14 are connected with self-tapping screws 34. A water guide channel 33 is welded and fixed to one side of the galvanized steel plate 11 and the other side to divert water and prevent water from pooling on the cantilevered steel structure pitched roof. Steel bars 38 further stabilize the bottom of the upper steel tie rod 9, lower steel tie rod 32, and water guide channel 33. The outer aluminum single panel 13 and the connecting plate 35 are connected with M20 high-strength bolts 36. The connecting plate 35 and the longitudinal steel frame beam 37 are connected with self-tapping screws. The galvanized steel plate 11 and the bent steel plate 14 are connected by self-tapping screws 34. The bent steel plate 14 is welded to the main structural truss beam 8 to strengthen the stability of the connection. Then, the metal roof panel 12 is placed on the upper surface of the galvanized steel plate 11. One end of the limiting screw 43 is fitted into the mounting hole 39 and passes through the metal roof panel 12, the galvanized steel plate 11, and the fixed square tube 10. The other end of the limiting screw 43 abuts against the upper surface of the metal roof panel 12. At this time, the fastening sleeve 42 is twisted. Since there is a threaded fit between the fastening sleeve 42 and the fixed shell 40, the fastening sleeve 42 will continuously descend within the fixed shell 40. Then, the forks at the upper end of the fastening clamp 41 are all tapered. The tapered surface of the clamp engages with the inner tapered surface at the bottom of the fastening sleeve 42 to continuously tighten it.This clamps the limiting screw 43, and then the nut 44 is threadedly connected to one end of the limiting screw 43. Under the tightening and limiting action of the limiting screw 43, the metal roof panel 12 is fixedly installed on the galvanized steel plate 11. This simplifies the installation and disassembly process of the metal roof panel 12, improves efficiency, and enhances overall practicality.
