Description
Technical Field
[0001] This invention relates to the field of wind-resistant roof structures, and more particularly to a large-span metal roof ridge structure that is resistant to strong winds. Background Technology
[0002] The level of construction technology for large-span spatial steel structures is an important indicator of a country's or region's architectural technology level and a reflection of its comprehensive national strength. In recent years, with the development of transportation, economy, and population, the construction of high-speed railway stations has become increasingly widespread, and people's pursuit of high-speed railway station construction has gradually shifted towards large spans, large spaces, and unique and beautiful shapes.
[0003] Metal roofing systems, as the external envelope of building structures, play a crucial role in ensuring structural safety. This safety primarily involves the roofing system's waterproofing, fire resistance, wind resistance, and durability. Because the panel connections in metal roofing systems typically employ mechanical interlocking connections, such as standing seam braces, rigid connections cannot be achieved. This leads to frequent incidents of metal roof panels being blown off by strong winds, severely impacting the normal operation of various large public buildings, especially transportation hubs, causing serious disasters, economic losses, and even casualties. Furthermore, due to the significant and prolonged effects of wind loads in coastal areas, and the frequent occurrence of typhoons, even if the metal roof is not instantly blown off by strong winds, the connections between metal roof panels and between the panels and the structure can loosen and fail due to long-term effects of temperature and wind loads, especially in wind-load-sensitive areas like the ridge. Damage to metal roof panels also directly leads to rainwater infiltration, damaging the waterproofing and insulation layers, resulting in high rework and repair costs, and affecting the normal functionality of the structure.
[0004] Therefore, how to develop a new type of large-span metal roof ridge structure resistant to strong winds has become an urgent problem for technicians in this field. Summary of the Invention
[0005] The purpose of this invention is to provide a large-span metal roof ridge structure that is resistant to strong winds, thereby solving the problem of poor wind and water resistance of existing metal roof ridge structures.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] This invention discloses a large-span metal roof ridge structure resistant to strong winds, comprising rectangular steel pipes, ridge support square pipes, ridge vertical square pipes, profiled square pipes, and edge sealing square pipes. Two rectangular steel pipes are respectively arranged on the left and right sides of the ridge splice joint, and the rectangular steel pipes are parallel to the ridge splice joint. A ridge support square pipe is welded between the two rectangular steel pipes. The upper surface of the ridge support square pipe is welded to the lower end face of the ridge vertical square pipe. The ridge vertical square pipe is vertically inserted into the ridge splice joint. Profiled square pipes are welded to the left and right sides of the upper end of the ridge vertical square pipe. An edge sealing square pipe is welded to the end of the profiled square pipe away from the ridge vertical square pipe. A metal roof structure is provided between the edge sealing square pipe and the rectangular steel pipes.
[0008] Furthermore, the metal roof structure, from bottom to top, consists of a main structural layer, a bottom roof layer, a sound-absorbing layer, an air-insulating layer, a thermal insulation layer, a waterproof layer, an isolation layer, and a top metal roof layer.
[0009] Furthermore, the main structural layer includes a purlin system, which includes an upper purlin structure and a lower purlin structure; the rectangular steel pipe is located inside the main structural layer and is connected to the purlin system by hexagonal head screws.
[0010] Furthermore, the roof subfloor includes a roof base plate, which is positioned above a rectangular steel pipe. A U-shaped support is positioned above the roof base plate, and the U-shaped support and the rectangular steel pipe are on the same straight line. The rectangular steel pipe, the roof base plate, and the U-shaped support are anchored together by hexagonal head screws. The roof base plate is integrally laid out, and a hole is opened at the middle surface of the ridge of the roof base plate to mate with the vertical square tube of the ridge.
[0011] Furthermore, the sound-absorbing layer includes ultra-fine glass fiber cotton and a Z-shaped support, the Z-shaped support being located directly above the rectangular steel pipe, and ultra-fine glass fiber cotton being laid on the upper end of the roof floor.
[0012] Furthermore, the air-barrier layer includes an air-barrier plastic sheet, which is laid on ultra-fine glass fiber cotton; the air-barrier plastic sheet is laid out as a whole, and a hole is opened at the middle surface of the ridge of the air-barrier plastic sheet to cooperate with the vertical square tube of the ridge.
[0013] Furthermore, the insulation layer includes a U-shaped purlin and insulation cotton. The U-shaped purlin is positioned directly above the U-shaped support and is fixedly connected to the U-shaped support by hexagonal head screws. The insulation cotton is laid on top of the air-tight plastic sheeting.
[0014] Furthermore, the waterproof layer includes a waterproof membrane, which is laid on top of the insulation layer. The waterproof membrane is laid out as a whole, and a hole is opened at the middle surface of the ridge of the waterproof membrane to cooperate with the vertical square tube of the ridge. The side of the vertical square tube of the ridge is wrapped with a layer of waterproof membrane, and the waterproof membrane is fixed to the side of the vertical square tube of the ridge by stainless steel clamps.
[0015] Furthermore, the isolation layer includes a T-shaped bracket and thermal insulation cotton. The lower surface of the T-shaped bracket is fixed to the purlin with hexagonal head screws. The top of the T-shaped bracket extends into the top layer of the metal roof. The height of the T-shaped bracket is equal to the sum of the thickness of the isolation layer and the top layer of the metal roof. Thermal insulation cotton is laid on top of the waterproof membrane.
[0016] Furthermore, the top layer of the metal roof includes metal roof panels, with metal roof panels laid on both sides of the ridge splice joint. The metal roof panels are wavy, with the inner layer of the crests locked into the upper part of the T-shaped brackets for edge locking and fixation. Hexagonal head screws are used to connect the metal roof panels and the T-shaped brackets. Wind-resistant clips are installed on the outer layer of the metal roof panels through connecting bolts. Drip edge is laid along the upper surface of the profiled square tube and the edge-sealed square tube. The drip edge covers the upper surface of the profiled square tube and the edge-sealed square tube, as well as the side surface and the left and right end faces of the edge-sealed square tube, and hangs down a certain distance. Pressure plates are laid on the upper surface of the wind-resistant clips and the drip edge. The pressure plates are anchored to the upper part of the wind-resistant clips by bolts.
[0017] Compared with the prior art, the beneficial technical effects of the present invention are as follows:
[0018] This invention relates to a large-span metal roof ridge structure resistant to strong winds. Rectangular steel pipes, Z-shaped supports, Z-shaped purlins, and T-shaped brackets are connected together using hexagonal head screws to form the central main connecting section. The bottom rectangular steel pipes are then connected to the main structural layer, and the upper metal roof panels are connected to the T-shaped brackets, achieving a connection between the top layer of the metal roof and the main structure, significantly increasing the wind resistance of the metal roof panels. Furthermore, this invention's large-span metal roof ridge structure welds rectangular steel pipes, vertical square tubes for the ridge, square tubes supporting the ridge, profiled square tubes, and edge-sealing square tubes into a single unit, known as an umbrella-shaped reinforcement layer. The drip edges and pressure plates laid on the surfaces of the profiled and edge-sealing square tubes at the top of the umbrella-shaped reinforcement layer extensively cover the gaps in the ridge splicing joints, improving the ridge's impermeability. Simultaneously, because the bottom rectangular steel pipes of the umbrella-shaped reinforcement layer are connected to the purlins of the main structural layer, the stability of the upper ridge components is increased. In summary, the wind-resistant, large-span metal roof ridge structure of this invention is ingeniously designed and practically functional, effectively solving the problem of poor wind and water resistance in existing metal roof ridge structures.

[0022] like Figure 1 As shown, a large-span metal roof ridge structure resistant to strong winds includes a metal roof structure and an umbrella-shaped reinforcement layer.
[0023] The umbrella-shaped reinforcement layer includes a rectangular steel tube 11, a ridge support square tube 10, a ridge vertical square tube 9, a profiled square tube 12, and an edge-sealing square tube 13.
[0024] Two rectangular steel pipes 11 are respectively installed on the left and right sides of the ridge splice joint. The rectangular steel pipes 11 are parallel to the ridge splice joint. A ridge support square tube 10 is welded between the two rectangular steel pipes 11. The distance between the left and right rectangular steel pipes 11 matches the length of the ridge support square tube 10, with an error between 3-5mm, to facilitate the welding of the ridge support square tube 10 as described later. The upper surface of the ridge support square tube 10 is welded to the lower end face of the ridge vertical square tube 9. The ridge vertical square tube 9 is vertically inserted into the ridge splice joint. A profiled square tube 12 is welded to the left and right sides of the upper end of the ridge vertical square tube 9. An edge-sealing square tube 13 is welded to the end of the profiled square tube 12 away from the ridge vertical square tube 9. The edge-sealing square tube 13 is parallel to the center seam of the ridge.
[0025] Since the umbrella-shaped reinforcement layer acts as a structural skeleton, supporting the installation of roof insulation and waterproofing structures, the welding between the umbrella-shaped reinforcement layers needs to be precise and the welding strength needs to meet the standards.
[0026] A metal roof structure is provided between the edge-sealed square tube 13 and the rectangular steel tube 11.
[0027] The metal roof structure consists of, from bottom to top, the main structural layer, the bottom layer of the roof, the sound-absorbing layer, the air-insulating layer, the thermal insulation layer, the waterproof layer, the isolation layer, and the top layer of the metal roof.
[0028] The space formed between the rectangular steel pipe 11 and the profiled square pipe 12 is used to lay the roof bottom layer, sound-absorbing layer, air-barrier layer, heat-insulating layer, waterproof layer, isolation layer and metal roof top layer. The distance between the rectangular steel pipe 11 and the profiled square pipe 12 is approximately the sum of the heights of each layer, with an error not exceeding 5mm.
[0029] The main structural layer includes a purlin system 19, which includes an upper purlin structure and a lower purlin structure; the rectangular steel pipe 11 is located inside the main structural layer and is connected to the purlin system 19 by hexagonal head screws 18.
[0030] The roof subfloor includes a roof base plate 20, which is positioned above a rectangular steel pipe 11. A U-shaped support 3 is located above the roof base plate 20, and the U-shaped support 3 and the rectangular steel pipe 11 are aligned on the same straight line. The rectangular steel pipe 11, the roof base plate 20, and the U-shaped support 3 are anchored together by hexagonal head screws 18. The roof base plate 20 is integrally laid out, and a hole for mates with the vertical square tube 9 of the ridge is opened at the middle surface of the roof base plate 20. The thickness of the roof base plate 20 is 0.8 mm.
[0031] The sound-absorbing layer includes ultra-fine glass fiber cotton 1 and a Z-shaped support 3. The Z-shaped support 3 is located directly above the rectangular steel pipe 11. After the Z-shaped support 3 is installed, ultra-fine glass fiber cotton 1 is laid on the upper end of the roof base plate 20. The thickness of the ultra-fine glass fiber cotton 1 is 50mm.
[0032] The air-barrier layer includes an air-barrier plastic veneer 2, which is laid on top of ultra-fine glass fiber cotton 1. The air-barrier plastic veneer 2 is integrally laid out, and a hole is opened at the middle surface of the ridge of the air-barrier plastic veneer 2 to mate with the vertical square tube 9 of the ridge. The thickness of the air-barrier plastic veneer 2 is between 0.25mm and 0.3mm. During construction, avoid sharp objects that could damage or destroy the integrity of the veneer.
[0033] The insulation layer includes a Z-shaped purlin 5 and insulation cotton 4. The Z-shaped purlin 5 is positioned directly above the Z-shaped support 3 and is fixedly connected to the Z-shaped support 3 by hexagonal head screws 18. The insulation cotton 4 is laid tightly and evenly on top of the air-tight plastic sheeting 2 and has a thickness of 50mm.
[0034] The waterproof layer includes a waterproof membrane 6, which is laid on top of the insulation layer. The waterproof membrane 6 is laid out as a whole, and a hole is opened at the middle surface of the ridge of the waterproof membrane 6 to cooperate with the vertical square tube 9 of the ridge. The side of the vertical square tube 9 of the ridge is wrapped with a layer of waterproof membrane 6, and the waterproof membrane 6 is fixed to the side of the vertical square tube 9 of the ridge by stainless steel clamps 16.
[0035] The isolation layer includes a T-shaped bracket 17 and thermal insulation cotton 4. The lower surface of the T-shaped bracket 17 is fixed to the purlin 5 by a hexagonal head screw 18. The top of the T-shaped bracket 17 extends into the top layer of the metal roof. The height of the T-shaped bracket 17 is equal to the sum of the thickness of the isolation layer and the top layer of the metal roof. Thermal insulation cotton 4 is laid on top of the waterproof membrane 6. The thickness of the thermal insulation cotton 4 is 50mm.
[0036] The top layer of the metal roof includes metal roof panels 7. Metal roof panels 7 are laid on both sides of the ridge splice joint. The metal roof panels 7 are wavy. The inner layer of the wave crest is locked into the upper part of the T-shaped bracket 17 for edge locking and fixation. Hexagonal head screws 18 are used to connect the metal roof panels 7 and the T-shaped bracket 17. The outer layer of the wave crest of the metal roof panels 7 is provided with wind-resistant clips 8 by connecting bolts 21. Drip edge 14 is laid along the upper surface of the profiled square tube 12 and the edge-sealed square tube 13. The drip edge 14 covers the upper surface of the profiled square tube 12 and the edge-sealed square tube 13, as well as the side surface and the left and right end faces of the edge-sealed square tube 13, and hangs down a certain distance, about 30mm.
[0037] The upper surfaces of the wind-resistant clamp 8 and the water-repellent plate 14 are covered with pressure plates 15, which are anchored to the upper part of the wind-resistant clamp 8 by bolts.
[0038] The construction process of this invention is as follows:
[0039] S1. Roof base construction: Based on the shape and size of the main roof structure, the roof base plate 20 is laid on site. The thickness of the roof base plate 20 is about 0.8mm. The roof base plate 20 is located between the rectangular steel pipe 11 and the Z-shaped support 3. The rectangular steel pipe 11, the roof base plate 20 and the Z-shaped support 3 are anchored together using hexagonal head screws 18. In addition, the roof base plate 20 is laid as a whole. A hole is opened on site in the middle of the ridge for the vertical square tube 9 of the ridge to pass through. The size of the hole is slightly larger than the cross-sectional size of the vertical square tube 9 of the ridge to facilitate the insertion of the vertical square tube 9 of the ridge. Due to size issues, the broken parts of the roof panel at other locations are anchored by overlapping to make the structure integrated.
[0040] S2. Sound-absorbing layer construction: Lay the Z-shaped support 3 on the roof base plate 20. The Z-shaped support 3 is positioned directly above the rectangular steel pipe 11. After the Z-shaped support 3 is installed, lay ultra-fine glass fiber cotton 1 tightly and evenly on the upper part of the roof base plate 20 with a thickness of about 50mm. The Z-shaped support 3 should also be filled with ultra-fine glass fiber cotton 1 to better achieve the sound absorption effect.
[0041] S3. Construction of the vapor barrier layer: After the sound absorption layer is completed, the vapor barrier plastic sheet 2 is laid on the top of the sound absorption layer. A hole is made on site in the middle of the ridge for the vertical square tube 9 of the ridge to pass through. The size of the hole is slightly larger than the cross-sectional size of the vertical square tube 9 of the ridge to facilitate the insertion of the vertical square tube 9 of the ridge. For other parts where the vapor barrier plastic sheet 2 is broken due to size issues, the structure can be integrated by overlapping and anchoring. In addition, the thickness of the vapor barrier plastic sheet 2 is between 0.25mm and 0.3mm. During construction, avoid sharp objects to damage or destroy the integrity of the sheet.
[0042] S4. Insulation layer construction: Above the air barrier layer, according to the dimensions in the construction drawing, install the Z-shaped purlins 5 one by one above the Z-shaped supports 3. Use connecting bolts 21 to fix the Z-shaped purlins 5 and the Z-shaped supports 3, thereby achieving the effect of force transmission and making the structure more stable. After the Z-shaped purlins 5 are fixed, lay the insulation cotton 4 tightly and evenly on the air barrier plastic sheet 2, with a thickness of about 50mm. The gaps of the Z-shaped purlins 5 should also be filled with insulation cotton 4 to better play the role of insulation.
[0043] S5. Waterproofing layer construction: The waterproof membrane 6 is laid along the surface of the insulation layer. A hole is made in the middle of the ridge for the vertical square tube 9 of the ridge to pass through. The size of the hole is slightly larger than the cross-sectional size of the vertical square tube 9 of the ridge to facilitate the insertion of the vertical square tube 9 of the ridge. For the remaining parts of the waterproof membrane 6 that are broken due to size issues, the structure can be integrated by overlapping and anchoring. A layer of waterproof membrane 6 is wrapped around the surface of the vertical square tube 9 of the ridge in the middle of the ridge. At the same time, stainless steel clamps 16 are used to fix the waterproof membrane 6 to the vertical square tube 9 of the ridge to achieve a better waterproofing effect.
[0044] S6. Isolation layer construction: According to the construction drawings, locate the position of the Z-shaped purlin 5 installed in the insulation layer above the waterproof membrane 6. Fix the lower surface of the T-shaped bracket 17 above the Z-shaped purlin 5 with hexagonal head screws 18. The upper part of the T-shaped bracket 17 extends into the top layer of the metal roof. The height of the T-shaped bracket 17 is approximately the sum of the height of the isolation layer and the top layer of the metal roof. In addition, lay the insulation cotton 4 tightly and evenly on top of the waterproof membrane 6, with a thickness of approximately 50mm.
[0045] S7. Construction of the top layer of metal roof: Integral metal roof panels 7 are laid on both sides of the splicing seam of the ridge. Due to size issues, the broken parts of the metal roof panels 7 are installed by overlapping. At the same time, the metal roof panels 7 are wavy, with the inner layer of the crests inserted into the upper part of the T-shaped brackets 17. Hexagonal head screws 18 are used to connect the metal roof panels 7 and the T-shaped brackets 17. After the metal roof panels 7 are laid, wind-resistant clips 8 are clamped on the outer layer of the crests of the metal roof panels 7 and fixed with connecting bolts 21, thereby fixing the metal roof panels 7 to the T-shaped brackets 17. At the same time, due to the layered connection of the lower connectors of the metal roof panels 7, the metal roof panels 7 are indirectly fixed to the main structural layer, improving wind resistance. A layer of pressure plate 15 is laid along the upper surface of the wind-resistant clips 8 and the drip edge 14, and the pressure plate 15 is anchored to the upper part of the wind-resistant clips 8. On the one hand, the pressure plate 15 plays a role in sealing the entire structure, and on the other hand, the pressure plate 15 can also block wind and water, improving the wind resistance and impermeability of the structure.
