Description

Technical Field

[0001] This invention relates to the field of building roofing technology, specifically to a modular assembled metal roof. Background Technology

[0002] Metal roofing is a type of roofing that uses metal sheets as the roofing material, integrating the structural layer and waterproofing layer into one unit. There are many types of metal sheets available, including galvanized steel sheets, aluminized zinc sheets, aluminum alloy sheets, aluminum-magnesium-manganese alloy sheets, titanium alloy sheets, copper sheets, and stainless steel sheets. Given the shortcomings of corrugated steel roofing in terms of waterproofing and durability, aluminum-magnesium-manganese alloy roofing is often a better choice for large public venues such as airports, stadiums, and theaters to meet their high-standard usage requirements.

[0003] As per existing technology, patent CN217326024U discloses a metal roof ridge cover, comprising joists spaced apart on the roof surface to be installed, multiple roof tiles, and a ridge plate that mates with the roof tiles. The multiple roof tiles are interconnected and respectively mounted on the joists on both sides of the ridge plate. Each roof tile has an installation notch, and both ends of the ridge plate are respectively positioned within the installation notches on the roof tiles on both sides. This type of metal roof ridge cover reduces the gap between the ridge plate and the roof surface by providing installation notches on the roof tiles, reducing the risk of the ridge plate being blown off in strong winds, effectively improving the roof's waterproofing performance. Furthermore, it eliminates the need for ridge waterproofing plugs, reducing construction costs and solving the problem of ridge waterproofing plug detachment. It is also simple to install, of high quality, and suitable for the installation of most similar aluminum-magnesium-manganese roof panels.

[0004] The metal roof in the aforementioned patent still has certain drawbacks:

[0005] In the aforementioned metal roof installation process, the installation of roof tiles needs to be carried out in steps. First, the brackets need to be fixed to the keel with bolts, and then the roof tiles are installed on the keel. However, since the brackets need to be securely connected to the keel with bolts, additional drilling is required after the keel is initially assembled to secure the brackets. This series of operations results in a long time spent working at height during the entire metal roof installation process, which not only increases the difficulty of construction but also brings significant safety hazards. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a modular, assembled metal roof, which reduces the time required for high-altitude operations and lowers safety hazards.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a modular assembled metal roof, comprising a main beam, keel, and purlins. Roofing tiles are provided on the top of the purlins, and hook blocks are provided at the bottom of the roofing tiles. The hook blocks are fixed to the roofing tiles by fixing bolts and are matched with the purlins. An anti-detachment component is connected to the side of the hook block away from the main beam. Connecting blocks are provided on both sides of the roofing tiles, and the connecting blocks are fixed to the roofing tiles by connecting bolts. Positioning blocks are provided below two adjacent roofing tiles, with both ends of the positioning blocks matching the connecting blocks and the middle position of the positioning blocks matching the keel. A ridge plate is fixed to the top of the main beam, and installation components are fixed to both ends of the bottom of the ridge plate. A reinforcing component is provided below the roofing tiles, and the reinforcing component matches the positioning block.

[0008] Furthermore, the roofing tile is composed of a top plate, a filling layer, and a bottom plate, with the top plate located on top of the bottom plate and the filling layer located between the top plate and the bottom plate.

[0009] Furthermore, the installation assembly includes a first side plate, a second side plate, and a positioning rod. The tops of both the first and second side plates are fixedly connected to the bottom of the ridge plate. The opposing surfaces of the first and second side plates abut against the two sides of the main crossbeam, respectively. The bottom of the second side plate is rotatably connected to the positioning rod, and the top of the positioning rod is in contact with the bottom of the main crossbeam. The lower end of the first side plate has a slot that matches the positioning rod.

[0010] Furthermore, a storage groove is provided on the side of the first side plate away from the main crossbeam, and a stop block is rotatably connected inside the storage groove.

[0011] Furthermore, guide blocks are fixed to both sides of the first and second side plates, and the guide blocks abut against the keel.

[0012] Furthermore, the anti-detachment component includes a rotating rod, a baffle, a limiting block, and a limiting plate. The lower end of the hook block away from the main crossbeam is fixedly connected to the rotating rod, and the upper end of the hook block away from the main crossbeam has an L-shaped limiting groove. The rotating rod is fitted with a baffle, which is rotatably connected to the rotating rod. The top of the baffle is fixedly connected to a limiting block that matches the limiting groove, and one side of the baffle is rotatably connected to a limiting plate.

[0013] Furthermore, the reinforcement component includes a reinforcement rod, a threaded rod, a rotating block, a pressing block, and a wedge-shaped locking block. Both ends of the reinforcement rod are slidably connected to wedge-shaped locking blocks, which match the purlins. Two symmetrically arranged pressing blocks are provided between the two wedge-shaped locking blocks. A threaded rod is threadedly connected to the middle position of the pressing block. The upper end of the threaded rod is rotatably connected to the reinforcement rod. The lower end of the threaded rod passes through the pressing block and the lower end of the reinforcement rod and extends to the outside of the reinforcement rod. A rotating block is fixedly connected to the lower end of the threaded rod.

[0014] Furthermore, sliders are fixed to both sides of the wedge-shaped block, and grooves are provided on both sides inside the reinforcing rod, with the sliders matching the grooves.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This type of modular assembled metal roof requires measuring various data, such as the purlin spacing, before fixing the roof tiles to the purlins. Then, the positions of the hook blocks and connecting blocks on the roof tiles are determined according to the installation position of the roof tiles. Subsequently, the hook blocks and connecting blocks can be fixed to the roof tiles on the ground. When fixing the roof tiles to the purlins, the roof tiles are first hoisted into place on the purlins using external hoisting equipment. Then, the roof tiles can be moved and hooked onto the purlins using the hook blocks. This greatly reduces the time spent working at height and lowers safety hazards.

[0017] 2. In this type of modular assembled metal roof, after the roof tiles are hooked onto the purlins by the hook blocks, the baffle is first slid to align the limiting block with the notch of the limiting groove. Then, the baffle is rotated so that the limiting block is in the limiting groove. Subsequently, the baffle is pushed to displace the limiting block from the notch of the limiting groove, and the limiting plate is moved so that the limiting plate abuts against the end of the groove where the rotating rod is located, thereby restricting the baffle and preventing the roof tiles from detaching from the purlins.

[0018] 3. In this type of modular assembled metal roof, after the roof tiles are fixed to the purlins by hook blocks, the positioning blocks are inserted into the connecting blocks to connect two adjacent roof tiles together. This allows multiple roof tiles to be connected into a whole, improving the overall stability of the metal roof. Attached Figure Description

[0030] 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.

[0031] Please see Figures 1 to 10A modular assembled metal roof includes a main beam 1, a keel 2, and purlins 3. Roofing tiles 4 are mounted on the top of the purlins 3, and hook blocks 9 are mounted on the bottom of the roofing tiles 4. The hook blocks 9 are fixed to the roofing tiles 4 by fixing bolts 8. The hook blocks 9 match the purlins 3. An anti-detachment component is connected to the side of the hook blocks 9 away from the main beam 1. Connecting blocks 23 are mounted on both sides of the roofing tiles 4, and the connecting blocks 23 are fixed to the roofing tiles 4 by connecting bolts 24. Positioning blocks 25 are located below two adjacent roofing tiles 4. The two ends of the positioning blocks 25 match the connecting blocks 23, and the middle position of the positioning blocks 25 matches the keel 2. A ridge plate 15 is fixed to the top of the main beam 1, and installation components are fixed to both ends of the bottom of the ridge plate 15. A reinforcing component is located below the roofing tiles 4, and the reinforcing component matches the positioning block 25.

[0032] In this invention, the modular assembled metal roof is assembled by first installing and fixing the main beams 1, keels 2, and purlins 3 onto the roof. Then, the roof tiles 4 and ridge panels 15 can be installed. Before fixing the roof tiles 4 onto the purlins 3, various data are measured, such as the spacing of the purlins 3 and the spacing of the keels 2. Then, the positions of the hook blocks 9 and connecting blocks 23 on the roof tiles 4 are determined based on their installation positions. Subsequently, the hook blocks 9 and connecting blocks 23 are fixed to the roof tiles 4 on the ground using fixing bolts 8 and connecting bolts 24, respectively. After completing the above preparations, the roof tiles 4 can be fixed onto the purlins 3. When installing the roof tile 4, simply use external hoisting equipment to hoist the roof tile 4 onto the purlin 3, then move the roof tile 4 so that the hook block 9 hooks onto the purlin 3. This greatly reduces the time spent working at height and lowers safety hazards. After the roof tile 4 is fixed onto the purlin 3 by the hook block 9, insert the positioning block 25 into the connecting block 23. The end of the positioning block 25 abuts against the purlin 3, thereby connecting two adjacent roof tiles 4 together. This allows multiple roof tiles 4 to be connected into a whole, improving the overall stability of the metal roof. Furthermore, if the width of the roof tile 4 is equal to the spacing between the keel 2, the positioning block 25 can also be stuck at the bottom of the keel 2, thereby restricting the roof tile 4 and making the roof tile 4 more securely installed.

[0033] When installing the ridge panel 15, the first side panel 16 and the second side panel 17 are welded and fixed to the bottom of the ridge panel 15 on the ground according to the measured spacing of the keel 2. After the first side panel 16 and the second side panel 17 are fixed to the ridge panel 15, the ridge panel 15 is hoisted into position on the main beam 1 using external hoisting equipment, so that the first side panel 16 and the second side panel 17 are on both sides of the main beam 1. After the ridge panel 15 is hoisted into position, it is fixed using the installation components. At the same time, due to various connecting accessories (such as hooks) Block 9, connecting block 23, first side plate 16 and second side plate 17, etc. can all be connected and fixed on the ground. Their installation steps are staggered with those of the roof tile 4, so the two steps can be carried out simultaneously. That is, some workers fix the connecting parts and some workers install the roof tile 4, thereby improving the installation efficiency. After the ridge plate 15 is installed, sealant can be used to fill the gap between the roof tile 4 and the ridge plate 15. In addition, since the main beam 1, keel 2 and purlin 3 in this invention are all existing mature products, they will not be described in detail here.

[0034] As a preferred embodiment of the present invention, the roof tile 4 is composed of a top plate 5, a filling layer 6 and a bottom plate 7, with the top plate 5 located on top of the bottom plate 7 and the filling layer 6 located between the top plate 5 and the bottom plate 7.

[0035] Specifically, the filling layer 6 can be made of sound insulation material or heat insulation material. At the same time, the surfaces of the top plate 5 and the bottom plate 7 can be sprayed with waterproof coating or corrosion-resistant coating to improve the waterproof and corrosion-resistant performance of the roof tile 4.

[0036] As a preferred embodiment of the present invention, the installation assembly includes a first side plate 16, a second side plate 17, and a positioning rod 18. The tops of the first side plate 16 and the second side plate 17 are fixed to the bottom of the ridge plate 15. The opposite surfaces of the first side plate 16 and the second side plate 17 abut against the two sides of the main crossbeam 1. The bottom of the second side plate 17 is rotatably connected to the positioning rod 18. The top of the positioning rod 18 fits against the bottom of the main crossbeam 1. The lower end of the first side plate 16 is provided with a slot 19 that matches the positioning rod 18.

[0037] Specifically, after the ridge panel 15 is hoisted and positioned on the main crossbeam 1, the positioning rod 18 can be rotated to insert the positioning rod 18 into the slot 19. In this way, the positioning rod 18 can restrict the first side panel 16 and the second side panel 17, preventing the ridge panel 15 from detaching from the main crossbeam 1.

[0038] As a preferred technical solution of the present invention, a storage groove 20 is provided on the side of the first side plate 16 away from the main crossbeam 1, and a stop block 21 is rotatably connected inside the storage groove 20.

[0039] Specifically, when the positioning rod 18 enters the slot 19, the stop block 21 can be rotated to restrict the positioning rod 18 and prevent it from dislodging from the slot 19.

[0040] As a preferred embodiment of the present invention, guide blocks 22 are fixedly connected to both sides of the first side plate 16 and the second side plate 17, and the guide blocks 22 abut against the keel 2. The guide blocks 22 can play a guiding role, making the installation of the ridge plate 15 more convenient.

[0041] As a preferred embodiment of the present invention, the anti-detachment component includes a rotating rod 11, a baffle 12, a limiting block 13, and a limiting plate 14. The lower end of the hook block 9 away from the main crossbeam 1 is fixedly connected to the rotating rod 11. The upper end of the hook block 9 away from the main crossbeam 1 has an L-shaped limiting groove 10. The rotating rod 11 is fitted with a baffle 12. The baffle 12 is rotatably connected to the rotating rod 11. The top of the baffle 12 is fixedly connected to a limiting block 13 that matches the limiting groove 10. The limiting plate 14 is rotatably connected to one side of the baffle 12.

[0042] Specifically, after the roof tile 4 is hooked onto the purlin 3 by the hook block 9, first slide the baffle 12 to align the limiting block 13 with the notch of the limiting groove 10. Then rotate the baffle 12 to place the limiting block 13 in the limiting groove 10. Next, push the baffle 12 to displace the limiting block 13 from the notch of the limiting groove 10, and move the limiting plate 14 to abut against the end of the groove where the rotating rod 11 is located, thereby restricting the baffle 12. This will prevent the roof tile 4 from detaching from the purlin 3.

[0043] As a preferred embodiment of the present invention, the reinforcement assembly includes a reinforcement rod 26, a threaded rod 27, a rotating block 28, a pressing block 29, and a wedge-shaped locking block 30. Both ends of the reinforcement rod 26 are slidably connected to the wedge-shaped locking blocks 30, which are matched with the purlin 3. Two symmetrically arranged pressing blocks 29 are provided between the two wedge-shaped locking blocks 30. A threaded rod 27 is threadedly connected to the middle position of the pressing block 29. The upper end of the threaded rod 27 is rotatably connected to the reinforcement rod 26. The lower end of the threaded rod 27 passes through the pressing block 29 and the lower end of the reinforcement rod 26 and extends to the outside of the reinforcement rod 26. The rotating block 28 is fixedly connected to the lower end of the threaded rod 27.

[0044] Specifically, if the width of the roof tile 4 is not equal to the spacing between the keel 2, causing the positioning block 25 to fail to engage with the keel 2, the reinforcing rod 26 can be placed between the two connecting blocks 23. Then, the rotating block 28 is rotated to rotate the threaded rod 27. Since the two sides of the pressing block 29 abut against the two sides of the reinforcing rod 26, the pressing block 29, which is threadedly connected to the threaded rod 27, will move in the direction of the rotating block 28. The pressing block 29 pushes the wedge-shaped locking block 30, causing the wedge-shaped locking block 30 to engage with the purlin 3, thereby fixing the reinforcing rod 26 between the two keels 2. Then, the positioning block 25 can be inserted into the connecting block 23 from below the reinforcing rod 26 to restrict and fix the roof tile 4, making the roof tile 4 more stable.

[0045] As a preferred technical solution of the present invention, sliders 32 are fixedly connected to both sides of the wedge-shaped block 30, and grooves 31 are opened on both sides inside the reinforcing rod 26, with sliders 32 matching grooves 31.

[0046] Specifically, the wedge-shaped block 30 is restricted by the slider 32 and the groove 31, making it easier for the wedge-shaped block 30 to move.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.
