Detailed Implementation
[0027] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.
[0028] With the advancement of science and technology, metal materials are widely used in the construction industry, and metal roofing has become a popular choice, especially integrated tile roofing systems. In related technologies, the junction between the parapet wall or gable wall and the roof is a weak point in waterproofing. Improper handling at this junction can allow rainwater to seep into the building, affecting indoor life and production. The parapet wall or gable wall, located at the edge of the building, easily accumulates debris and dirt, making it difficult to clean and potentially harboring grime. Furthermore, traditional methods for this junction are complex, making future leak repairs difficult. After a roof leak occurs, the complexity of traditional methods leads to high maintenance and repair costs. Traditional waterproofing measures at this junction involve hot-air welding a portion of the waterproof membrane to the integrated tile roof panel, then flipping up the other portion of the waterproof membrane and fixing it to the wall joists using self-tapping screws. This method is relatively complex, requires more manpower, and carries a significant risk of leakage.
[0029] Figure 1 A schematic diagram of the structure of a gable cover plate having a crest portion according to an embodiment of the first aspect of this application is shown. Figure 2 A schematic diagram of the structure of a gable cover plate having two crests is shown according to an embodiment of the first aspect of this application. Figure 3 A schematic diagram of a gable cover plate with three crests according to an embodiment of the first aspect of this application is shown. Figures 1 to 3 As shown, the gable cover 10 includes a first cover 11 and a second cover 12 with an integral structure.
[0030] The first cover plate 11 is used to seal and cover a portion of the adjacent roof panel 20 of the wall panel 30, thereby minimizing the size of the first cover plate 11 in the third direction and saving materials and costs. The first cover plate 11 has a certain length along the first direction and includes a plurality of troughs 111 that appear periodically in the first direction, and crests 112 that connect adjacent troughs 111. The crests 112 protrude from the troughs 111 in the second direction. For example, the first cover plate 11 has two, three, four, or five troughs 111 in the first direction, and correspondingly has one, two, three, or four crests 112. In this embodiment, the number of troughs 111 is multiple, which means at least two. Therefore, in addition to the number used as an example above, there can be other numbers of troughs 111 and crests 112. In this way, different numbers of crests and troughs of the gable cover plate 10 can be selected as needed, which can adapt to the wall panel 30 on the one hand, and avoid waste caused by cutting or increased installation costs caused by splicing and welding on the other hand. For example, the first cover plate 11 is a plate with uniform thickness. This makes the gable joint more aesthetically pleasing after installation, and the uniform wall thickness is beneficial for hot air welding construction.
[0031] The second cover plate 12 is used to seal and cover a portion of the adjacent wall panel 30 of the roof panel 20, thereby minimizing the size of the second cover plate 12 in the second direction and saving materials and costs. The second cover plate 12 is disposed at the third-direction end of the first cover plate 11 and on the side of the first cover plate 11 with the crest portion 112. The second cover plate 12 is integrally connected with the trough portion 111 and the crest portion 112. When the gable cover plate 10 is used in the gable node structure, the second cover plate 12 is located at the lower end of the first cover plate 11 in the third-direction. Exemplarily, the second cover plate 12 is a plate of uniform thickness, which makes the installed gable node more aesthetically pleasing and facilitates hot air welding construction. Exemplarily, the first cover plate 11 and the second cover plate 12 have equal thickness, which facilitates integral structure forming and reduces production costs.
[0032] It should be noted that the first direction is the length direction of the first cover plate 11. When the gable cover plate 10 is used in the gable node structure, the first direction refers to the extension direction of the gable node, that is, the extension direction of the gable and the roof joint, or the direction of the intersection line of the wall panel 30 and the roof panel 20. The second direction is the direction perpendicular to the trough 111, that is, the thickness direction of the trough 111 or the thickness direction of the peak plane of the crest 112. The third direction refers to the width direction of the first cover plate 11.
[0033] The one-piece molded gable cover plate 10, by setting a second cover plate 12 on the side of the first cover plate 11 with the crest 112, can be used as a base to sit on the roof panel 20 during construction, so that the first cover plate 11 can be directly attached to the wall panel 30. Unlike the use of waterproof membrane, there is no need to "flip up" part of it, nor is it necessary to use self-tapping screws for fixing. This simplifies construction, reduces labor, and improves the fit. With the help of hot air welding, it is durable and has a good sealing effect, effectively reducing the risk of water leakage. Whether it is the initial installation or the later replacement, it is simple and easy.
[0034] In one embodiment, the gable end cap 10 is made of the same material as the waterproof layer of the wall panel 30 and / or the roof panel 20. For example, the waterproof layer of the roof panel 20 and / or the waterproof layer of the wall panel 30 is made of thermoplastic polyolefin or polyvinyl chloride, and correspondingly, the gable end cap 10 is made of thermoplastic polyolefin or polyvinyl chloride. The thermoplastic polyolefin material, specifically a novel waterproof material made from thermoplastic polyolefin (TPO) synthetic resin that combines ethylene propylene rubber and polypropylene using advanced polymerization technology, with the addition of antioxidants, anti-aging agents, and softeners, can be made into a reinforced waterproof material using polyester fiber mesh as the internal reinforcing material, and belongs to the category of synthetic polymer waterproof materials.
[0035] By designing the material of the gable cover plate 10 to be consistent with the material of the waterproof layer of the roof panel 20 and / or wall panel 30, it is easy to carry out welding operations of homogeneous materials, and ensure the seal between the gable cover plate 10 and the wall panel 30 and between the gable cover plate 10 and the roof panel 20.
[0036] In one embodiment, the trough portions 111 at both ends of the first direction are 0.5 times larger in the first direction than the trough portions 111 between two adjacent crest portions 112. For example, the trough portions 111 at both ends of the first direction are 50-80 mm longer in the first direction than the trough portions 111 between two adjacent crest portions 112. This makes the dimensions of the overlapping portions of adjacent gable end caps 10 more reasonable, ensuring the connection strength at the overlap.
[0037] Thus, during the installation of the gable cover plate 10, adjacent gable cover plates 10 can overlap, and the overlap is fixed by hot air welding, so that the adjacent gable cover plates 10 form a whole, with good structural stability, good waterproof effect and good heat insulation effect.
[0038] Figure 4 A cross-sectional schematic diagram of a gable joint structure according to an embodiment of the second aspect of this application is shown. Figure 4 As shown, the gable node structure includes a roof panel 20, a wall panel 30, and a gable cover plate 10 in any of the above embodiments.
[0039] The roof panel 20 is laid on the roof. In this embodiment, the roof panel 20 is located at the gable joint structure, so the roof panel 20 in this embodiment is adjacent to the gable. Exemplarily, the roof panel 20 may include a support layer and a waterproof layer covering one side of the support layer. The support layer may be a thermoplastic polyolefin metal sheet (fusion tile), and the material of the waterproof layer is consistent with the material of the gable cover 10, which can reduce the types of materials of the roof panel 20 assembly 10. After the roof panel 20 is installed, the support layer is located inside the roof system, and the waterproof layer is located outside the roof system, so that the waterproof layer can play its due waterproof role.
[0040] The wall panel 30 is installed on the side of the gable facing the roof panel 20. Exemplarily, the wall panel 30 may include a support layer and a waterproof layer covering one side of the support layer. The support layer may be a thermoplastic polyolefin metal sheet (fused tile), and the material of the waterproof layer is the same as that of the gable cover 10, which can reduce the types of materials in the roofing system. After installation, the support layer of the wall panel 30 is on the side facing the gable, and the waterproof layer is on the side away from the gable, so that the waterproof layer can perform its due waterproofing function.
[0041] The gable end cap 10 covers a portion of the roof panel 20 and a portion of the wall panel 30 on the outside. Specifically, the first end cap 11 covers a portion of the wall panel 30 near the roof panel 20, and the second end cap 12 covers a portion of the roof panel 20 near the wall panel 30. In this way, the amount of material used for the gable end cap 10 can be minimized, thus saving costs.
[0042] Thus, by setting a gable cover plate 10 at the junction of the gable wall and the roof (i.e., the angle between the roof panel 20 and the wall panel 30), and using the second cover plate 12 of the gable cover plate 10 to sit on the roof panel 20, the first cover plate 11 can be attached to the wall panel 30 without "flipping up" or nailing, which makes the joint treatment relatively simple and reduces labor costs. Moreover, the integrated gable cover plate 10 can effectively reduce the risk of water leakage after being sealed and fixed with the roof panel 20 and the wall panel 30.
[0043] In one embodiment, the gable node structure further includes a roof joist 40 and a first connector 50. The roof joist 40 is adjacent to the gable wall, and a portion of the roof panel 20 near the gable wall is laid on the roof joist 40. The first connector 50 is used to connect the roof panel 20 and the roof joist 40. A second cover plate 12 of the gable cover plate 10 covers the outer side of the roof panel 20 and at least covers the first connector 50. The edge of the second cover plate 12 is sealed and fixed to the roof panel 20. Exemplarily, the edge of the second cover plate 12 is fixed to the roof panel 20 by hot air welding. Exemplarily, the first connector 50 may include rivets, self-tapping screws, non-self-tapping screws, or other components that can serve a fixing connection function; preferably, the first connector 50 may use self-tapping screws for easy installation and good connection effect.
[0044] Thus, the roof joists 40 and the first connector 50 can firmly fix the edge of the roof panel 20 near the gable wall, preventing the roof panel 20 from warping at this location and thus avoiding damage to the welded gable cover plate 10; the second cover plate 12 covers the first connector 50 to prevent the first connector 50 from rusting; the edge of the second cover plate 12 is sealed and fixed to the roof panel 20 to prevent rainwater and dust and other impurities from entering the house or the interior of the roof structure through the gap between the first cover plate 11 and the roof panel 20.
[0045] In one embodiment, the gable node structure further includes a first gable joist 60 and a second connector 70. The first gable joist 60 is disposed on the gable and higher than the roof panel 20. The second connector 70 is used to connect a portion of the wall panel 30 near the roof panel 20 to the first gable joist 60. A first cover plate 11 of the gable cover plate 10 covers the outer side of the wall panel 30 and at least covers the second connector 70. The edge of the first cover plate 11 is sealed and fixed to the wall panel 30. Exemplarily, the edge of the first cover plate 11 is fixed to the wall panel 30 by hot air welding. Exemplarily, the second connector 70 may include rivets, self-tapping screws, non-self-tapping screws, or other components that can serve a fixing connection function; preferably, the second connector 70 may use self-tapping screws for easy installation and good connection effect.
[0046] Thus, the first gable joist 60 and the second connector 70 can firmly fix the edge of the wall panel 30 near the roof, preventing the wall panel 30 from lifting at this location and thus avoiding damage to the welded gable cover plate 10; the edge of the first cover plate 11 is sealed and fixed to the wall panel 30, preventing rainwater and dust and other impurities from entering the house or roof structure through the gap between the second cover plate 12 and the wall panel 30; the first cover plate 11 covers the second connector 70, preventing the second connector 70 from rusting.
[0047] In one embodiment, the gable joint structure further includes purlins 80, a third connector 90, and a first cover plate 100. A portion of the roof panel 20 is laid on the purlins 80. The third connector 90 connects the roof panel 20 and the purlins 80. The first cover plate covers the roof panel 20 and the third connector 90, and the edge of the first cover plate is sealed and fixed to the roof panel 20. Exemplarily, the third connector 90 may include rivets, self-tapping screws, non-self-tapping screws, or other components that can provide a fixed connection. Preferably, the third connector 90 may use self-tapping screws for easy installation and good connection. Exemplarily, the material of the first cover plate 100 is the same as that of the gable cover plate 10, which reduces the types of materials used in the roofing system. The edge of the first cover plate 100 is hot-air welded to the roof panel 20.
[0048] Thus, the roof panel 20 is fixed to the purlin 80 by the third connector 90, preventing the roof panel 20 from shifting and thus avoiding affecting the welded gable cover plate 10; the third connector 90 is covered by the first cover to prevent the third connector 90 from being corroded by rainwater; the edge of the first cover is sealed and fixed to the roof panel 20 to prevent rainwater, dust, etc. from entering the interior through the gap between the first cover and the roof panel 20, thus avoiding affecting the third connector 90.
[0049] In one embodiment, the gable joint structure further includes a roof insulation support layer 110 and a roof insulation layer 120. The roof insulation support layer 110 is disposed below the roof panel 20, a portion of which is supported on the purlin 80 and fixed by the third connector 90. The roof insulation layer 120 is disposed between the roof panel 20 and the roof insulation support layer 110. For example, the roof insulation support layer 110 may include wire mesh, and the roof insulation layer 120 may include expanded foam; both are conventional materials, saving costs.
[0050] Thus, by setting the roof insulation layer 120, the thermal insulation performance of the roof system can be effectively improved; by setting the roof insulation support layer 110, the roof insulation layer 120 can be prevented from falling off, thereby ensuring the thermal insulation performance.
[0051] In one embodiment, the gable node structure further includes a second gable joist 130, a fourth connector 140, and a second cover plate 150. The fourth connector 140 connects the wall panel 30 and the second gable joist 130. The second cover plate 150 covers the side of the wall panel 30 facing away from the gable and at least covers the fourth connector 140. The edge of the second cover plate 150 is sealed and fixed to the wall panel 30. Exemplarily, the fourth connector 140 may include rivets, self-tapping screws, non-self-tapping screws, or other components that can provide a fixed connection. Preferably, the fourth connector 140 may use self-tapping screws for easy installation and good connection. Exemplarily, the material of the second cover plate 150 is the same as that of the gable cover plate 10, which reduces the types of materials used in the roofing system. The edge of the second cover plate 150 is hot-air welded to the wall panel 30.
[0052] Thus, the wall panel 30 is fixed to the second gable joist 130 by the fourth connector 140, preventing the wall panel 30 from shifting and thus avoiding affecting the welded gable cover plate 10; the fourth connector 140 is covered by the second cover to prevent it from rusting due to rainwater; the edge of the second cover is sealed and fixed to the roof panel 20 to prevent rainwater, dust, etc. from entering the interior through the gap between the second cover and the wall panel 30, thus avoiding affecting the fourth connector 140.
