Description

Technical Field

[0001] This utility model relates to the field of steel structure building technology, and in particular to roof opening node system and metal roof. Background Technology

[0002] Steel structure buildings are widely used in current factory construction due to their advantages such as short construction period, strong structure, and low cost. The roof surface of steel structure buildings typically features multiple protruding peaks at intervals to enhance the roof's strength.

[0003] To ensure good lighting conditions inside buildings, skylights are typically installed in the roof. However, the openings for these skylights require cutting into the roof surface, resulting in corrugated sections at the openings. This corrugation leads to complex structures at the openings, necessitating the use of materials such as stainless steel, galvanized steel sheets with color steel plates, and aluminum panels to facilitate rainwater diversion and drainage. However, this method presents a significant risk of leakage and requires substantial auxiliary materials, resulting in high costs. Utility Model Content

[0004] In view of the above problems, this utility model embodiment is proposed. The purpose of this utility model embodiment is to provide a roof opening node system that is simple in structure and operation, low in cost, and has good sealing.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A roof opening node system, wherein an opening is provided on the roof surface, and multiple wave peaks are spaced apart on the roof surface, with a gap between the wave peaks and the opening;

[0007] The roof opening node system includes:

[0008] The first and second overlapping panels cover and connect with each other;

[0009] The first and second ramps are located opposite each other at the distance, and the side of the first and second ramps that are opposite to each other is flush with the bottom edge of the crest of the corresponding side.

[0010] Alternatively, the first and second approach plates are integrally formed with the roof surface.

[0011] Optionally, it also includes:

[0012] A support plate is located below the first and second platform plates and is mechanically connected to the first and second platform plates.

[0013] Optionally, a sealant may be provided between the first or second mounting plate and the support plate.

[0014] Optionally, a sealant is provided between the first and second mounting plates.

[0015] Alternatively, two opposite sides of the opening may span at least one of the wave crests, and the other two opposite sides may be located between two adjacent wave crests at their respective locations.

[0016] Optionally, it also includes:

[0017] A base is provided around the perimeter of the opening, and the base has a through hole aligned with the edge of the opening. A structure covering the opening is connected to the base and covers the through hole.

[0018] Optionally, a water-blocking structure is provided between the higher side of the base and the wave crest.

[0019] Optionally, the water-blocking structure includes:

[0020] Two water-blocking plates are connected to each other, with one side of the water-blocking plate connected to the base and the other side connected to a portion of the roof surface at the first and second access plates;

[0021] The connection between the two water baffles protrudes in a direction away from the base.

[0022] Another objective of this utility model embodiment is to provide a metal roof with a simple structure, easy operation, and good sealing for the roof opening node system.

[0023] To achieve this objective, the present invention adopts the following technical solution:

In other words, the positions of the first and second overlapping plates correspond to the positions of the corrugated peaks. Because of the overlapping and interlocking first and second overlapping plates, the roof surface around the opening is flat and unaffected by the corrugated peaks, thus achieving better sealing. The structure is simple, requires minimal material, is low-cost, and easy to operate. Attached Figure Description

[0038] This application provides a metal roof, which includes a roof surface 2. The roof surface 2 covers the top surface of a building to provide rain and snow protection. Typically, the roof surface 2 has different openings to meet various needs. For example, to meet ventilation and lighting requirements, the roof surface 2 has windows, or it has holes for bracing rods to pass through, which increase the roof's load-bearing capacity and resistance to wind and snow. To increase its rigidity and strength, the roof surface 2 usually has multiple corrugations 21 at intervals. When these openings 22 are made on the roof surface 2, the corrugations 21 at the corresponding positions must be cut, resulting in a complex cross-sectional shape of the openings 22, making them difficult to seal or install sealing structures.

[0039] To solve the above problems, please refer to Figure 1 As shown, the metal roof of this application also includes a roof opening node system 1. There is a gap between the opening 22 on the roof surface 2 and the crest 21. The roof opening node system 1 is located at the gap and surrounds the opening 22 in the circumference. It can eliminate the problem of complex cross-sectional shape of the opening 22 caused by the crest 21, so that the cross-section of the opening 22 is a regular slit, thereby ensuring sealing performance.

[0040] The roof opening node system 1 of this application can be applied to openings 22 on different roof surfaces 2, and the roof opening node system 1 of the corresponding size can be matched according to the size of the opening 22. Therefore, please refer to Figure 1As shown, the dimensions of the roof opening node system 1 in this application are not fixed, but the structural methods are the same. This makes the roof opening node system 1 of this application more widely applicable, not limited to skylight openings 22 or through openings 22, etc., but applicable to any opening 22 on the roof surface 2.

[0041] Specifically, please refer to Figure 2 As shown in some embodiments of this application, one possible structure of the roof opening node system 1 includes a first overlapping plate 11 and a second overlapping plate 12 that overlap each other. The first overlapping plate 11 and the second overlapping plate 12 are located opposite each other at the gap and extend towards each other, thereby achieving mutual overlap. Corresponding to the position of the crest 21, the side of the first overlapping plate 11 and the second overlapping plate 12 that is away from each other is flush with the bottom edge of the crest 21 on the corresponding side. That is to say, the gap should originally be the position of the crest 21, but in order to eliminate the influence of the shape of the crest 21 on the cross-sectional shape of the opening 22, the original crest 21 is replaced by the first overlapping plate 11 and the second overlapping plate 12, thereby making the cross-section of the opening flat and eliminating the influence of the shape of the crest 21.

[0042] The first slab 11 and the second slab 12 can be pre-fabricated during the construction of the roof surface 2, knowing the location of the opening 22 in advance. However, in many cases, the location of the opening 22 cannot be predicted in advance and must be cut on-site according to the actual situation. In such cases, please refer to... Figure 2 As shown, the structure of the first overlapping plate 11 and the second overlapping plate 12 can also be achieved by cutting off the top of the corrugated peak 21 that is 200mm away from the roof panel, and then manually flattening the remaining corrugated peaks 21 to achieve a flush state with the roof panel. This method offers greater flexibility. As long as the corrugated peaks 21 at the intervals have overlapping first overlapping plates 11 and second overlapping plates 12 at corresponding positions, this application does not impose specific limitations. The cut-off section of the original corrugated peak can be sealed with a sealant.

[0043] It should be noted that, please refer to Figure 2 As shown, the corrugations 21 are typically structures that bulge outwards from the roof panel. Therefore, by cutting off the top wall of the corrugations 21, the remaining length of the corrugations 21 must be greater than the length of the bottom of the corrugations 21. Thus, the remaining parts of the corrugations 21 can overlap each other after being flattened. In this case, the first overlapping plate 11, the second overlapping plate 12, and the roof surface 2 are integrally formed. There is no need to use other metal materials to seal the cross-section of the opening 22, which not only simplifies the structure but also reduces costs, and the structure at the opening 22 is more aesthetically pleasing.

[0044] Since the first slab 11 and the second slab 12 are separate rather than continuous, in order to ensure strength, in some embodiments of this application, the roof opening node system 1 further includes a support plate. The support plate is located below the first slab 11 and the second slab 12 and is mechanically connected to the first slab 11 and the second slab 12. The mechanical connection can be either screwed or riveted, thereby ensuring the structural strength at the opening 22.

[0045] Furthermore, in some embodiments of this application, please refer to Figure 2 As shown, a sealant 13 is provided between the first mounting plate 11 and the second mounting plate 12, and a sealant 13 or a sealant 13 tape or other sealing element is also provided between the support plate and the first mounting plate 11 or the second mounting plate 12 that are in contact with it, so as to ensure good sealing performance.

[0046] In some embodiments of this application, two opposite sides of the opening 22 span at least one wave crest 21, while the other two opposite sides are located between two adjacent wave crests 21 at their respective positions. This ensures that only one pair of opposite sides of the opening 22 is affected by the wave crest 21, while the other pair of opposite sides is unaffected. This reduces the impact of the wave crest 21 on the opening structure.

[0047] Furthermore, in some embodiments of this application, please refer to Figure 1 As shown, the roof opening node system 1 also includes a base 14, which surrounds the periphery of the opening 22 and has through holes aligned with the edge of the opening 22. The structure covering the opening 22 is connected to the base 14 and covers the through holes. The structure covering the opening 22 can be a window or a trim piece conforming to the shape of the tie rod, as long as it can achieve the sealing of the opening 22; this application does not impose specific limitations. The base 14 can provide support and installation for the structure sealing the opening 22, thereby simplifying installation. In other words, the roof opening node system 1 can serve as a standard structure at the opening to increase the strength of the opening structure and eliminate the influence of the complex cross-section of the opening 22, ensuring the continuity of the roof panel at the top of the opening 22, significantly reducing leakage points, improving aesthetics, and meeting the installation requirements of other components, thus promoting standardized operations.

[0048] It is understandable that the roof surface 2 is at a certain angle to facilitate the sliding of rain and snow. The crests 21 are set along the tilt direction of the roof surface 2, so the opening 22 cuts the opposite sides of the crests 21. One side is located at a higher position and the other side is located at a lower position. Since the side located at the higher position spans multiple crests 21, the opening 22 will obstruct the water diversion effect of the water diversion channel formed by two adjacent crests 21. The water diversion channel will lead the rainwater to the roof opening node system 1. Long-term erosion by rainwater will affect the sealing of the roof surface 2.

[0049] Therefore, in some embodiments of this application, please refer to Figure 1 As shown, the roof opening node system 1 also includes a water-blocking structure 15, which is located between the higher side of the base 14 and the crest 21. Rainwater flowing from the water inlet channel reaches the roof opening node system 1 and comes into contact with the water-blocking structure 15. The water-blocking structure 15 then diverts the rainwater to both sides of the opening 22, allowing it to exit through adjacent water inlet channels. This prevents the roof opening node system 1 from being subjected to prolonged rainwater impact, ensuring good sealing. Furthermore, the water-blocking structure 15 also strengthens the structural strength of the base 14.

[0050] Furthermore, in some embodiments of this application, the water-blocking structure 15 includes two water-blocking plates connected opposite to each other. One side of the water-blocking plate is connected to the base 14, and the other side is connected to a portion of the roof surface 2 at the first ramp 11 and the second ramp 12. The connection point of the two water-blocking plates protrudes in a direction away from the base 14. That is, the water-blocking structure 15 is equivalent to a rhombus, while the water-blocking plates are triangular, specifically isosceles triangles. One of the two longer sides is connected to the base 14, and the other is connected to a portion of the roof surface 2 at the first ramp 11 and the second ramp 12. The shorter side of the isosceles triangle is the side where the two water-blocking sides connect, and this side protrudes in a direction away from the base 14, thereby making the water-blocking plate a water-diverting plate that guides the flow of water.

[0051] It should be noted that all places requiring connection in this application embodiment need to have a sealing structure to ensure that the roof opening 22 node system 1 has good sealing performance.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
