Description

Technical Field

[0001] This utility model relates to the field of steel structure building technology, specifically to a roof structure for a steel structure building. Background Technology

[0002] Steel structure buildings are frequently used due to their fast construction and low cost. The roof of a steel structure building includes a ridge, beams, and purlins. The ridge is located at the center of the roof, and beams and purlins are typically arranged in a crisscross pattern on both sides of the ridge. Specifically, multiple purlins are arranged at intervals, and beams are located at both ends of all purlins, fixing them in place. The beams and purlins are perpendicular to each other. Traditional steel structure buildings (usually factories) use roof structures made by splicing multiple corrugated steel sheets onto the roof purlins and then fastening them with screws. However, this method has the following problems: 1. The corrugated steel sheets are easily corroded at the screw holes; 2. Leakage occurs at the horizontal overlaps between the corrugated steel sheets.

[0003] To overcome the aforementioned water seepage and leakage problems, roof overlapping structures using concealed fixing seats have gradually emerged in the market. For example, the utility model patent with authorization announcement number CN201395897Y and authorization announcement date of February 3, 2010, discloses an arc-shaped interlocking joint structure for a light steel plant roof panel, including a roof panel and a fixing seat. The roof panel is installed on the roof purlin through the concealed fixing seat. The roof panel is composed of several overlapping panels, and the joint of adjacent roof panels is located at the crest of the roof panel. Furthermore, the male and female overlapping edges of adjacent roof panels are designed to be arc-shaped, and the two are connected as one unit by mechanical interlocking.

[0004] The technical solutions disclosed in the aforementioned patent documents still have certain limitations in practical operation, as follows:

[0005] The roof panels disclosed in the aforementioned patent documents are planar structures. Although such planar roof panels can fit closely to the roof purlins, they can be blown away or lifted up in strong winds. This is because the airflow impacts the roof panels from different angles. When the airflow comes into contact with the roof panels, since the bottom of the roof panels is flat, the airflow can directly impact the bottom of the roof panels. With small impacts, the roof panels may only sway, but once the impact is large, the center of the flat surface of the roof panels will bulge, and in severe cases, they may even detach from the roof purlins.

[0006] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0007] This utility model provides a roof structure for steel structure buildings, aiming to solve the technical problems mentioned in the background art.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is: a roof structure for a steel structure building, wherein the roof of the steel structure building includes longitudinally and transversely arranged beams and purlins, the upper surfaces of the beams and the purlins together forming a roof mounting surface, the roof structure being positioned and connected to the roof mounting surface, and the roof structure including roof panels and fixed supports.

[0009] Based on the top view projection of the roof structure, the long side of each roof panel is perpendicular to the purlin, and the end of the roof panel extends to overlap the ridge. Each roof panel is sequentially interlocked along the length of the purlin to form a tiled roof covering structure for covering the roof mounting surface. The fixing bracket is disposed on the roof mounting surface and is configured to position and connect the roof panel to the roof mounting surface.

[0010] Based on the cross-section of the roof panel;

[0011] The roof panel includes a steel plate with an upper arc surface and a lower arc surface arranged opposite to each other. The lower arc surface is an arc-shaped convex surface protruding towards the roof mounting surface, and the upper arc surface is an arc-shaped groove recessed towards the roof mounting surface. The arc bottom of the upper arc surface is directly opposite the arc bottom of the lower arc surface, so that the center of gravity of the steel plate converges at a point.

[0012] The relevant content in the above plan is explained as follows:

[0013] In the above scheme, the roof mounting surface refers to the upper surface of the roof, which is composed of beams and purlins. Therefore, the fixing brackets are set on the purlins of the roof.

[0014] In the above scheme, the fixing bracket can be a bolt or other fastener. Once multiple roof panels interlock to form a tile covering structure for covering the roof, they can be fixed with screws or other components.

[0015] In the above solution, the arc-shaped groove can also collect rainwater, so that when the rainwater flows, it will only come into contact with the bottom of the arc-shaped groove most of the time. During maintenance, only a targeted anti-corrosion coating needs to be sprayed onto the bottom of the arc.

[0016] In the above scheme, the combination of the arc-shaped convex surface and the arc-shaped groove can not only concentrate the center of gravity of the steel plate at one point to improve the impact resistance of the steel plate, but also disperse the incoming airflow due to the arc-shaped convex surface, so that it will not directly impact the bottom of the steel plate, reducing the chance of the steel plate being overturned.

[0017] In a further technical solution, the centers of the upper arc surface and the lower arc surface are at the same point, and the upper arc surface and the lower arc surface are formed by bending the steel plate downwards.

[0018] A further technical solution is that when the roof panel is positioned and connected to the roof mounting surface, the lower arc surface of the steel plate abuts against the roof mounting surface.

[0019] The above design ensures that the gap between the arc-shaped convex surface and the arc-shaped groove is not too large, which reduces costs without affecting the strength of the steel plate, achieving a good balance between the two.

[0020] A further technical solution is to take the cross-section of the roof panel as a reference, and provide a first edge structure and a second edge structure at both ends of the steel plate respectively. The first edge structure has an insertion part, and the second edge structure has an interlocking part. The interlocking part is located outside the upper arc surface, and the interlocking part has a groove that matches the insertion part.

[0021] When adjacent roof panels interlock, the interlocking portion on the preceding steel panel is configured to engage with the insertion portion on the following steel panel via a groove.

[0022] The above design allows adjacent roof panels to interlock quickly. Specifically, the interlocking part can be a vertical panel or a vertical P-shaped structure.

[0023] During the engagement operation, align the groove on the engagement part of the preceding steel plate with the insertion part on the following steel plate, and then insert the groove and the insertion part together to complete the engagement operation.

[0024] A further technical solution is to provide a plurality of fixed supports spaced apart along the length of the roof panel. The bottom end of the fixed support is positioned and connected to the purlin of the roof. The upper end of the fixed support has a bent portion. The bent portion is provided with a positioning groove that matches the insertion portion. When the fixed support is positioned on the roof, the positioning groove is configured to position the insertion portion on the first overlapping structure.

[0025] When adjacent roof panels interlock, the insertion part, the bending part, and the interlocking part are sequentially interlocked from bottom to top.

[0026] After adjacent roof panels interlock, they need to be fixed with brackets. If screws are used directly, the color steel plate at the screws and nail holes is prone to corrosion. Therefore, the above design ensures that the adjacent roof panels will not move freely after interlocking. Specifically, during the interlocking operation, once the groove on the interlocking part of the previous steel plate is aligned with the insertion part on the next steel plate, the guide bend is positioned between the groove and the insertion part. Then, they are engaged in sequence. That is to say, when adjacent roof panels interlock, the insertion part, the bend part, and the interlocking part are interlocked sequentially from bottom to top.

[0027] It should be noted that when adjacent roof panels interlock, the end of the interlocking part away from the steel plate extends beyond the insertion part and the bend. Then, a bending mechanism (such as a bending machine) is used to fold the extended end of the interlocking part to achieve further fixation.

[0028] A further technical solution, based on the cross-section of the roof panel, the first overlapping structure includes a first extension plate integrally connected to one end of the steel plate. The end of the first extension plate is provided with a curved section. The curved section is formed by bending the end of the first extension plate toward the inner side of the upper arc surface. The curved section and the first extension plate are combined to form a U-shaped structure with a cross-section. The U-shaped structure is the insertion part.

[0029] With the above design, the stability is higher when the plug-in part is fixed to the bending part. Although the plug-in part can be a vertical plate or a vertical P-shaped structure, its stability is not as good as that of the U-shaped structure. When the U-shaped structure is plugged into the positioning groove on the bending part, the inner sidewall of the positioning groove will abut against the two sides of the U-shaped structure to achieve full fixation.

[0030] A further technical solution, based on the cross-section of the roof panel, includes a second extension plate integrally connected to the end of the steel plate. The end of the second extension plate is integrally connected to the interlocking part and combined to form a frame structure that matches the shape of the U-shaped structure. The frame structure has an opening facing the roof mounting surface, and the groove is formed in the frame structure. The opening is the slot of the groove.

[0031] The above design enhances stability when the insertion, bending, and interlocking parts mesh together. For details, please refer to [reference needed]. Figure 1 , Figure 2 , Figure 5 and Figure 6 If the opening extends beyond the insertion part and the bend, the extended end of the engagement part can be flanged using a bending mechanism (such as a bending machine) to achieve further fixation.

[0037] The working principle and advantages of this utility model are as follows:

[0038] In this invention, the combination of the arc-shaped convex surface and the arc-shaped groove not only allows the center of gravity of the steel plate to be concentrated at one point, thereby improving the impact resistance of the steel plate, but also, due to the setting of the arc-shaped convex surface, the incoming airflow can be dispersed, preventing it from directly impacting the bottom of the steel plate and reducing the chance of the steel plate being overturned.

[0048] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0049] Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0050] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.

[0051] See appendix Figures 1-7 As shown, a roof structure of a steel structure building is provided. The roof of the steel structure building includes longitudinally and transversely arranged beams and purlins 101. The upper surfaces of the beams and purlins 101 together form a roof mounting surface 1. The roof structure is positioned and connected to the roof mounting surface 1. The roof structure includes roof panels 2 and fixed supports 3.

[0052] Based on the top view projection of the roof structure, the long side of each roof panel 2 is perpendicular to the purlin 101, and the end of the roof panel 2 extends to overlap the ridge 102. Each roof panel 2 is sequentially interlocked along the length of the purlin 101 to form a tile covering structure for covering the roof mounting surface 1. The fixing bracket 3 is set on the roof mounting surface 1 and is configured to position and connect the roof panel 2 to the roof mounting surface 1.

[0053] Based on the cross-section of roof panel 2;

[0054] The roof panel 2 includes a steel plate 4, which has an upper arc surface 5 and a lower arc surface 6 arranged opposite to each other. The lower arc surface 6 is an arc-shaped convex surface protruding towards the roof mounting surface 1, and the upper arc surface 5 is an arc-shaped groove 11 recessed towards the roof mounting surface 1. The arc bottom of the upper arc surface 5 is directly opposite the arc bottom of the lower arc surface 6 so that the center of gravity of the steel plate 4 converges at a point.

[0055] In this embodiment, the roof mounting surface 1 refers to the upper surface of the roof, which is composed of beams and purlins 101. Therefore, the fixing bracket 3 is set on the purlins 101 of the roof.

[0056] In this embodiment, the fixing bracket 3 can be a bolt or other fastener. Once multiple roof panels 2 interlock to form a tile covering structure for covering the roof, they can be fixed with screws or other components.

[0057] In this embodiment, the arc-shaped groove 11 can also collect rainwater, so that when the rainwater flows, it will only contact the bottom of the arc-shaped groove 11 most of the time, and only the anti-corrosion coating needs to be sprayed on the bottom of the arc during maintenance.

[0058] In this embodiment, the combination of the arc-shaped convex surface and the arc-shaped groove 11 not only allows the center of gravity of the steel plate 4 to be concentrated at one point, thereby improving the impact resistance of the steel plate 4, but also, due to the setting of the arc-shaped convex surface, the incoming airflow can be dispersed, preventing it from directly impacting the bottom of the steel plate 4 and reducing the probability of the steel plate 4 being overturned.

[0059] Preferably, the centers of the upper arc surface 5 and the lower arc surface 6 are at the same point, and the upper arc surface 5 and the lower arc surface 6 are formed by bending the steel plate 4 downwards.

[0060] When the roof panel 2 is positioned and connected to the roof mounting surface 1, the lower arc surface 6 of the steel plate 4 abuts against the roof mounting surface 1.

[0061] With the above design, the gap between the arc-shaped convex surface and the arc-shaped groove 11 is not too large, which reduces costs without affecting the strength of the steel plate 4, achieving a good balance between the two.

[0062] Preferably, taking the cross-section of the roof panel 2 as a reference, the two ends of the steel plate 4 are respectively provided with a first overlapping structure 7 and a second overlapping structure 8. The first overlapping structure 7 has an insertion part 9, and the second overlapping structure 8 has an interlocking part 10. The interlocking part 10 is located outside the upper arc surface 5, and the interlocking part 10 has a groove 11 that matches the insertion part 9.

[0063] When adjacent roof panels 2 interlock, the interlocking portion 10 on the preceding steel plate 4 is configured to engage with the insertion portion 9 on the following steel plate 4 via a groove 11.

[0064] With the above design, adjacent roof panels 2 can quickly interlock. Specifically, the interlocking part 9 can be a vertical plate or a vertical P-shaped structure.

[0065] During the engagement operation, the groove 11 on the engagement part 10 of the previous steel plate 4 is aligned with the insertion part 9 on the next steel plate 4, and then the groove 11 and the insertion part 9 are inserted to complete the engagement operation.

[0066] Preferably, a plurality of fixed supports 3 are arranged at intervals along the length of the roof panel 2. The bottom end of the fixed support 3 is positioned and connected to the purlin 101 of the roof. The upper end of the fixed support 3 has a bent part 12. The bent part 12 is provided with a positioning groove 13 that matches the plug-in part 9. When the fixed support 3 is positioned on the roof, the positioning groove 13 is configured to position the plug-in part 9 on the first edge structure 7.

[0067] When adjacent roof panels 2 interlock with each other, the insertion part 9, the bending part 12 and the interlocking part 10 are sequentially interlocked from bottom to top.

[0068] After adjacent roof panels 2 interlock, they need to be fixed by a fixing bracket 3. If screws are used directly, there is a problem that the color steel plate 4 at the screws and nail holes is easily corroded. Therefore, with the above design, the adjacent roof panels 2 will not move freely after interlocking. Specifically, when the interlocking operation is performed, once the groove 11 on the interlocking part 10 on the previous steel plate 4 is aligned with the insertion part 9 on the next steel plate 4, the guiding bending part 12 is positioned between the groove 11 and the insertion part 9. Then, they are engaged in sequence. That is to say, when adjacent roof panels 2 interlock, the insertion part 9, the bending part 12, and the interlocking part 10 are interlocked in sequence from bottom to top.

[0069] It should be noted that the following provides a further fixing method for the insertion part 9, the bent part 12, and the engaging part 10, specifically, as follows: Figure 7 As shown, when adjacent roof panels 2 interlock, the end of the interlocking part 10 away from the steel plate 4 extends beyond the insertion part 9 and the bending part 12. Then, the overhanging end of the interlocking part 10 is further flanged by a bending mechanism (e.g., a bending machine) to achieve further fixation.

[0070] Preferably, based on the cross-section of the roof panel 2, the first overlapping structure 7 includes a first extension plate 14 integrally connected to one end of the steel plate 4. The end of the first extension plate 14 is provided with a curved section 15. The curved section 15 is formed by bending the end of the first extension plate 14 toward the inner side of the upper arc surface 5. The curved section 15 and the first extension plate 14 are combined to form a U-shaped structure with a cross-section. The U-shaped structure is the insertion part 9.

[0071] With the above design, the stability is higher when the plug-in part 9 is fixed to the bending part 12. Although the plug-in part 9 can be a vertical plate or a vertical P-shaped structure, its stability is not as good as that of the U-shaped structure. When the U-shaped structure is plugged into the positioning groove 13 on the bending part 12, the inner sidewall of the positioning groove 13 will abut against the two sides of the U-shaped structure to achieve full fixation.

[0072] Preferably, based on the cross-section of the roof panel 2, the second edge structure 8 includes a second extension plate 16 integrally connected to the end of the steel plate 4. The end of the second extension plate 16 is integrally connected to the interlocking part 10 and combined to form a frame structure that matches the shape of the U-shaped structure. The frame structure has an opening facing the roof mounting surface 1, and the groove 11 is formed in the frame structure. The opening is the slot of the groove 11.

[0073] The above design enhances stability when the insertion part 9, the bending part 12, and the engagement part 10 interlock. For details, please refer to... Figure 1 , Figure 2 , Figure 5 and Figure 6 The opening extends beyond the insertion part 9 and the bending part 12. At this time, the overhanging end of the engagement part 10 can be flanged by a bending mechanism (e.g., a bending machine) to achieve further fixation.

[0074] The working principle is to directly guide adjacent roof panels 2 to interlock with each other. During the interlocking operation, once the groove 11 on the interlocking part 10 of the preceding steel plate 4 is aligned with the insertion part 9 on the following steel plate 4, the guiding bending part 12 is positioned between the groove 11 and the insertion part 9. Then, they are engaged sequentially. That is, when adjacent roof panels 2 interlock with each other, the insertion part 9, the bending part 12, and the interlocking part 10 are interlocked sequentially from bottom to top. After the interlocking is completed, the opening extends beyond the insertion part 9 and the bending part 12. At this time, the extended end of the interlocking part 10 can be folded over and bent again by a bending mechanism (such as a bending machine) to achieve further fixation.

[0075] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
