[0054] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments in the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the embodiments of the present invention.

[0055] The inventor discovered during the practice of the embodiments of the present invention that in the prior art, when the standing seam roof system is in use, the roof panels are often damaged by strong winds. For example, at the eaves of a roof with a parapet, under the action of a large wind load, the connection between the roof panel and the gutter is easily damaged, resulting in gaps, which then produce a chain-unfastening effect and cause the overall wind damage of the roof system. If the snow melts or heavy rain fails to drain water in time and the gutter in the eaves overflows, rainwater will flow back from the above gaps, causing roof leakage, affecting the use function of the building.

[0056] The reason is that the current national standards and standard drawings are not perfect in detail construction, which makes leakage and overall wind damage of the standing seam roof system occur frequently during use, and has become a problem in the industry. According to the "Technical Specifications for Portal Frame Lightweight House Steel Structure" GB51022-2015, the metal roof eaves are located in the edge area of ​​the roof system, and the wind suction it bears is 1.67 times that of the middle area of ​​the roof, and the wind pressure at the corner of the roof is 2.5 times greater than that of the middle area, which belongs to the high wind pressure area. However, in the current national standard "Technical Specifications for Engineering Application of Corrugated Metal Sheets" GB50896 and the national standard drawing "Architectural Structure of Corrugated Metal Sheets" 17J925-1, the connection method between the roof panel and the purlin at the eaves is the same as that in the middle area of ​​the roof panel. The same sliding support connection is used without any reinforcement. Although the roof panel and the gutter are reinforced and fixed with self-tapping screws (or bolts), the gutter is only placed on the gutter bracket below. This connection method is ineffective against wind lifting. Therefore, under the action of large wind loads, the roof will be damaged from the corners and eaves, and then a chain-unfastening effect will occur, causing the overall wind-lifting damage of the roof system. This kind of wind-lifting damage to metal roofs often occurs in the southeast coastal areas of my country during the typhoon season.

[0057] In view of the above problems, the embodiments of the present invention provide a roof eaves structure, a roof system and a construction method, which can effectively prevent the eaves from being damaged by wind and greatly improve the wind resistance of the eaves structure.

[0058] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention is clearly and completely described below in combination with the accompanying drawings and specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0061] Figure 1 is a schematic structural diagram of a roof eave structure in an embodiment of the present invention, Figure 2is a schematic cross-sectional structure diagram of a roof eave structure in an embodiment of the present invention, Figure 3 for Figure 2 The enlarged schematic diagram of point A in the figure is as follows: Figures 1 to 3 shown.

[0062] An embodiment of the present invention provides a roof eaves structure, including: a roof purlin 10, an eaves support member 20, a roof panel 30 and a gutter assembly 40.

[0063] Among them, see Figure 2 The roof purlin 10 includes a first connecting portion 11 and a first supporting portion 12. Figure 3 The eaves support member 20 includes a second connection portion 21 and a second support portion 22. The gutter assembly 40 includes a third connection portion 41 and a third support portion 42. The first connection portion 11 of the roof purlin 10 is fixed in position, and the first support portion 12 is connected to the second connection portion 21 of the eaves support member 20.

[0064] Continue to see Figure 3 The second supporting portion 22 of the eaves supporting member 20, the third supporting portion 42 of the gutter assembly 40 and the roof panel 30 are stacked, wherein the second supporting portion 22 is preset with a plurality of rivet bolts 221 arranged at intervals along the length direction and integrally formed with the second supporting portion 22, and the third supporting portion 42 and the roof panel 30 are provided with pre-punched holes for use with the rivet bolts 221, and each rivet bolt 221 passes through the third supporting portion 42 and the roof panel 30 in turn, and is respectively connected to the nut 222 to fix the second supporting portion 22, the third supporting portion 42 and the roof panel 30.

[0065] See also Figure 2 , the third connection portion 41 of the gutter assembly 40 is fixed in position.

[0066] The technical solution provided by the embodiment of the present invention is to set an eaves support member 20, and realize the connection between the roof panel 30, the gutter assembly 40 and the roof purlin 10 through the eaves support member 20. The gutter assembly 40 and the roof panel 30 are positioned at the installation position by the rivet bolts 221 on the eaves support member 20 in cooperation with the pre-punched holes on the gutter assembly 40 and the roof panel 30, so that the installation position of the gutter assembly 40 and the roof panel 30 is accurate, and the components of the roof eaves structure are interlocked, and the structures are pressed and fixed, so as to avoid the loosening of the connection structure between the gutter assembly 40 and the roof panel 30, and the wind damage caused thereby, thereby greatly improving the overall wind resistance. At the same time, the third connection part 41 and the third support part 42 of the gutter assembly 40 are fixed, further improving the wind resistance.

[0067] It should be noted that the roof eaves structure provided in the embodiment of the present invention can be applied to the roof system, see Figure 2A feasible roof system includes a wall panel 100, a roof inner top plate 200 and a roof cornice structure. The roof cornice structure includes a plurality of roof panels 30, and two adjacent roof panels 30 are connected by a vertical lock seam structure. The first connection portion 11 of the roof purlin 10 is fixedly connected to the roof inner top plate 200, for example, it can be connected by a self-tapping screw. The third connection portion 41 of the gutter assembly 40 is fixedly connected to the wall panel 100, for example, it can be connected by a flat head self-tapping screw or a wall structure nail. Alternatively, the third connection portion 41 of the gutter assembly 40 and the wall panel 100 are both fixedly connected to the wall purlin 101, and the third connection portion 41 can be connected between the wall purlin 101 and the wall panel 100. After installation, a plug can be set in the nail hole on the wall panel 100. The plug can be used to prevent the nail head from being exposed, avoid corrosion, and be beautiful while performing waterproof treatment.

[0068] See also Figure 3 and Figure 4 In the embodiment of the present invention, one possible implementation of the eave support member 20 is that the eave support member 20 is formed by bending 1.6 mm thick S350 hot-dip galvanized Z275 high-strength structural steel. In order to further improve the bending rigidity of the eave support member 20, the second support portion 22 of the eave support member 20 is provided with a reinforcing fold 223, and the reinforcing fold 223 is bent away from the roof panel 30. For example, the reinforcing fold 223 and the second support portion 22 form an angle of approximately 90°, and the reinforcing fold 223 forms a stiffening rib of the second support portion 22. The height of the reinforcing fold 223 relative to the second support portion 22 can be 25 mm, that is, the reinforcing rib is 25 mm high, so as to improve the bending rigidity of the eave support member 20. Furthermore, in order to improve the bending rigidity of the second connection, in the embodiment of the present invention, the second connection portion 21 of the eave support member 20 is provided with a bending structure 211, and the bending structure 211 is bent away from the roof panel 30.

[0069] A plurality of rivet bolts 221 are arranged near the reinforcing fold 223 of the second support part 22. The rivet bolts 221 can be 304 stainless steel M6 flat head bolts, which are arranged on the second support part 22 by rivet. The rivet bolts 221 can be produced in the factory in advance and then taken to the construction site for use, which is convenient to use. In order to match the rivet bolts 221, a plurality of pre-punched holes are arranged at positions corresponding to the plurality of rivet bolts 221 on the roof panel 30, and the spacing between the plurality of rivet bolts 221 is consistent with the spacing between the plurality of pre-punched holes on the roof panel 30. A plurality of connection holes are arranged at intervals on the second connection part 21 on the eaves support 20, and the spacing between the plurality of connection holes is 300mm and the diameter is φ6.

[0070] When installing the roof panel 30 , the first connecting portion 11 of the roof purlin 10 is first fixed, for example, fixed on the inner top plate 200 of the roof.

[0071] Then, use φ5.5 self-tapping screws with a spacing of 300mm to pass through the connecting holes, fix the second connecting part 21 of the eaves support member 20 on the first supporting part 12 of the roof purlin 10, and the second supporting part 22 with the reinforced folded edge 223 is cantilevered outward to support the third supporting part 42 of the gutter assembly 40 and the roof panel 30.

[0072] Then, the third support part 42 of the gutter assembly 40 is installed on the second support part 22 of the eaves support 20. For example, a pre-punched hole with a diameter of φ8 is preset on the third support part 42, and the hole spacing is the same as that of the rivet bolts 221 on the second support part 22. The pre-punched holes on the third support part 42 are fixed through the stainless steel rivet bolts 221 on the eaves support 20.

[0073] Finally, the pre-punched hole on the roof panel 30 is passed through the rivet bolt 221 exposed from the third support portion 42, and the nut 222 is connected to the rivet bolt 221 to complete the final installation of the roof eaves structure. The nut 222 includes but is not limited to an M6 stainless steel flange nut 222 with a locking notch.

[0074] The rivet bolts 221 on the eaves support 20 are consistent in spacing with the third support portion 42 of the gutter assembly 40 and the pre-punched holes on the roof panel 30, and act as a positioning device, so that the multiple roof panels 30 installed in the roof eaves structure are interlocked. For example, the effective width of each roof panel 30 can be controlled at 468 mm.

[0075] Combination Figure 1 , see Figure 5 In the embodiment of the present invention, one possible implementation of the gutter assembly 40 is that the gutter assembly 40 includes a gutter body 401 and a plurality of gutter brackets 402. The gutter body 401 includes a first U-shaped body 4011, and a first supporting fold 4012 is provided on one side of the first U-shaped body 4011. The gutter bracket 402 includes a second U-shaped body 4021 matching the first U-shaped body 4011, and a second supporting fold 4022 matching the first supporting fold 4012 is provided on one side of the second U-shaped body 4021. The plurality of gutter brackets 402 are arranged at intervals along the length direction of the gutter body 401, and the second U-shaped body 4021 is sleeved outside the first U-shaped body 4011. The first supporting fold 4012 and the second supporting fold 4022 serve as the third supporting portion 42, and the other side of the first U-shaped body 4011 and the other side of the second U-shaped body 4021 serve as the third connecting portion 41.

[0076] The gutter body 401 includes but is not limited to being made by bending stainless steel, and the gutter bracket 402 includes but is not limited to being made by bending galvanized sheet. It should be noted that a thermal insulation layer made of thermal insulation cotton is also provided in the corresponding area of ​​the roof eaves structure, such as thermal insulation cotton is laid on the gutter bracket 402 along the length direction of the gutter body 401. In order to make the arrangement of the components in the figure clearer, the thermal insulation layer is not shown in the figure.

[0077] When installing the gutter assembly 40, the first support fold 4012 on the gutter body 401 may overlap with or not overlap with the second support fold 4022 on the gutter bracket 402. A portion of the rivet bolts 221 on the eaves support member 20 may pass through the first support fold 4012 and the second support fold 4022, and another portion of the rivet bolts 221 may pass through the first support fold 4012 directly, thereby achieving the connection between the eaves support member 20 and the gutter assembly 40. That is, the position of the third support portion 42 of the gutter assembly 40 is fixed.

[0078] The other side of the first U-shaped body 4011 and the other side of the second U-shaped body 4021 serve as the third connecting portion 41 and can be fixed respectively. Figure 6 , the other side of the second U-shaped body 4021 can be connected to the roof purlin 10 by a flat head bolt, and the other side of the first U-shaped body 4011 can be installed on the wall purlin 101 by a self-tapping screw, and then the wall panel 100 is installed on the gutter assembly 40. Alternatively, the wall panel 100 can also be placed on the wall purlin 101, and then the gutter assembly 40 is installed. After the installation is completed, a plug can be set in the nail hole on the wall panel 100. The plug can be used to prevent the nail head from being exposed while performing waterproof treatment, avoid corrosion, and be beautiful. That is, the position of the third connecting portion 41 of the gutter assembly 40 is fixed. The third connecting portion 41 and the third supporting portion 42 of the gutter assembly 40 are both fixed, which further improves the wind resistance performance.

[0079] Combination Figure 1 and Figure 5 , see Figure 3 In order to further improve the waterproof performance of the roof eaves structure, in the embodiment of the present invention, the roof eaves structure further includes a waterproof component 50, which is located between the roof panel 30 and the third support portion 42 and connected to the third support portion 42. The waterproof component 50 can seal the gap between the roof panel 30 and the third support portion 42 to prevent rainwater from entering the roof system. For example, when snow melts or heavy rain cannot be drained in time, causing the gutter component 40 in the roof eaves structure to overflow, the waterproof component 50 can prevent rainwater from flowing back from the gap between the roof panel 30 and the third support portion 42 to cause roof leakage.

[0080] In the embodiment of the present invention, one possible implementation of the waterproof component 50 is: Figure 1 and Figure 5 The waterproof assembly 50 includes a waterproof tape 51 and a plurality of waterproof plugs 52. Figure 1 and Figure 5 , see Figure 3 The waterproof tape 51 extends along the length direction of the third support portion 42 and is sleeved on a plurality of rivet bolts 221. A plurality of waterproof plugs 52 are arranged at intervals along the length direction of the third support portion 42 and connected to the third support portion 42. Each waterproof plug 52 is located at a connection position of two roof panels 30, and the shape of the waterproof plug 52 matches the shape of the connection position of the two roof panels 30.

[0081] The waterproof tape 51 includes but is not limited to a butyl tape. The size of the butyl tape can be adjusted according to different waterproof requirements. The size of a butyl tape can be 4.8 mm thick, 20 mm wide, and the length matches the length of the third support member. The waterproof plug 52 includes but is not limited to a rubber plug.

[0082] When installing the roof panel 30, after the third support portion 42 of the gutter assembly 40 is installed on the second support portion 22 of the eaves support member 20, a waterproof tape 51 is laid on the third support portion 42, and the center line of the length direction of the waterproof tape 51 coincides with the connection line of multiple rivet bolts 221. According to the width of the roof panel 30, multiple waterproof plugs 52 are installed at intervals of 468 mm. The connection position of the two roof panels 30 forms a plate rib, and the shape of the waterproof plug 52 matches the plate rib between the two roof panels 30. In order to further improve the waterproof performance, a waterproof layer is provided on the side of the waterproof plug 52 facing the roof panel 30. The waterproof layer includes but is not limited to butyl tape. After laying the waterproof tape 51 and the waterproof plug 52, the roof panel 30 is connected by the rivet bolts 221.

[0083] The shape of the waterproof plug 52 matches the shape of the connection position of the two roof panels 30, thereby ensuring that the ribs of the roof panel 30 are tightly fitted with the waterproof plug 52, and the waterproof plug 52 can provide corresponding support for the roof panel 30. The stacked structure formed by the roof panel 30, the waterproof assembly 50, the third support part 42 of the gutter assembly 40 and the eaves support member 20 is pressed and fixed to ensure absolute density, effectively solving the chronic problem of leakage at the roof eaves structure.

[0084] In the embodiment of the present invention, the roof panel 30 includes but is not limited to a cold-bent thin-walled member with a thickness of 0.6-0.8 mm and an opening. In order to avoid the situation where the cross-sectional shape is easily deformed due to its own low rigidity. Figure 1 and Figure 5The roof eaves structure also includes a reinforcing strip 60, which is sleeved on the rivet bolts 221 and connected to the roof panel 30 through nuts 222. When installing the roof panel 30, after the roof panel 30 is rivet on the bolts 221, the reinforcing strip 60 is sleeved on the rivet bolts 221 and pressed against the surface of the roof panel 30, and finally tightened and fixed with nuts 222. The reinforcing strip 60 can be used to press and fix the stacked structure formed by the roof panel 30, the waterproof component 50, the third support part 42 of the gutter component 40 and the eaves support member 20 to ensure absolute density. At the same time, the reinforcing strip 60 extends along the width direction of the roof panel 30, and can be used as a stiffening rib in the width direction of the roof panel 30 to increase the wind resistance and bending stiffness of the roof panel 30.

[0085] The reinforcing bead 60 includes but is not limited to being made of aluminum alloy material, and the size of the reinforcing bead can be set according to different requirements, for example, it can be set to 3mm thick and 32mm wide, and the length can be set accordingly according to the width of the roof panel 30. The reinforcing bead 60 is made of aluminum alloy material, which itself will produce a dense oxide protective film after oxidation in the air, with excellent anti-corrosion performance, and will not produce electrochemical reaction with the roof panel 30, avoiding contact corrosion between the roof panel 30 and the reinforcing bead 60, and improving the durability of the roof system.

[0086] Further, in order to avoid water accumulation at the connection between the reinforcing strip 60 and the roof panel 30, see Figure 7 , a plurality of grooves 61 are arranged on the reinforcing strip 60 at intervals along the length direction, and are recessed in a direction away from the roof panel 30. The grooves 61 and the roof panel 30 enclose a drainage hole. The drainage hole is inclined along the slope of the roof panel 30, for example, inclined in the direction of the gutter assembly 40, so that the water on the roof panel 30 flows to the gutter assembly 40. The groove 61 structure can be used to guide water and act as a stiffening rib, increasing the bending rigidity of the reinforcing strip 60. After being fixed to the roof panel 30 with the M6 ​​stainless steel stop flange nut 222, the contact surface between the nut 222 and the roof panel 30 is increased, which plays a role in stress diffusion, and prevents the roof panel 30 from being torn and pulled off at the nut 222 under the action of strong wind, effectively solving the industry problem of wind damage to the roof panel 30 at the eaves. Furthermore, one roof panel 30 can be provided with one reinforcing strip 60, or multiple strips can be provided, which is not specifically limited here.

[0087] Continue to see Figure 7, the two opposite ends of the reinforcing strip 60 are respectively provided with warped edges 62, and the two warped edges 62 are respectively in contact with the male rib and the female rib of the roof panel 30. The warped edges 62 can strengthen the bending rigidity of the male rib and the female rib of the roof panel 30, and further prevent the connection between the two roof panels 30 from being damaged by wind. In the mode of providing the waterproof plug 52, the warped edges 62 on the reinforcing strip 60 and the waterproof plug 52 form a clamping structure, so that the male rib and the female rib of the roof panel 30 are more firmly connected, and the wind resistance is improved.

[0088] In the embodiment of the present invention, the roof eaves structure can be applied to the roof system, which solves the wind-uplift damage caused by the wind suction of the roof system, thereby greatly improving the overall wind-uplift resistance. It has high wind-uplift resistance and can be applied to high wind pressure areas or high wind pressure areas with high buildings, such as the strong typhoon areas in the southeast coastal area.

[0089] Accordingly, combined Figures 1 to 7 , see Figure 2 Accordingly, the embodiment of the present invention further provides a roof system, including: a wall panel 100, a roof inner top plate 200 and a roof cornice structure. The roof cornice structure can be implemented by the roof cornice structure described in the above embodiment. The specific scheme is as follows:

[0090] The embodiment of the present invention further provides a roofing system, comprising: a wall panel 100, a roof inner top plate 200 and a roof eaves structure.

[0091] The roof eaves structure includes: a roof purlin 10, an eaves support 20, a roof panel 30 and a gutter assembly 40. The roof purlin 10 includes a first connection portion 11 and a first support portion 12. The eaves support 20 includes a second connection portion 21 and a second support portion 22. The gutter assembly 40 includes a third connection portion 41 and a third support portion 42.

[0092] The first connection part 11 of the roof purlin 10 is fixedly connected to the inner roof plate 200, and the first support part 12 is connected to the second connection part 21 of the eave support member 20. The second support part 22 of the eave support member 20, the third support part 42 of the gutter assembly 40 and the roof panel 30 are stacked, wherein the second support part 22 is preset with a plurality of rivet bolts 221 arranged at intervals along the length direction toward the third support part 42, and each rivet bolt 221 passes through the roof panel 30 of the third support part 42 in sequence and is connected to the nut 222 respectively, so as to fix the second support part 22, the third support part 42 and the roof panel 30. The third connection part 41 of the gutter assembly 40 is fixedly connected to the wall panel 100.

[0093] It should be noted that the roof eaves structure included in the roof system can refer to the contents in the above embodiments, and will not be described in detail here.

[0094] Accordingly, see Figures 1 to 4 The embodiment of the present invention further provides a construction method of a roof eave structure, comprising:

[0095] Step S101: The first connection portion 11 of the roof purlin 10 is fixedly connected to the inner roof top plate 200, and the first support portion 12 of the roof purlin 10 is connected to the second connection portion 21 of the eaves support member 20;

[0096] The first connection portion 11 of the roof purlin 10 can be connected to the roof inner top plate 200 by self-tapping screws. Further, the first connection portion 11 can also be fixed to other components according to different setting positions.

[0097] Step S102: stacking the second support portion 22 of the eave support member 20, the third support portion 42 of the gutter assembly 40, and the roof panel 30; wherein the second support portion 22 is provided with a plurality of rivet bolts 221 arranged at intervals along the length direction and integrally formed with the second support portion 22; each rivet bolt 221 passes through the third support portion 42 and the roof panel 30 in sequence, and is connected to the nut 222 respectively, so as to fix the second support portion 22, the third support portion 42, and the roof panel 30 together;

[0098] In order to better achieve the connection, pre-punched holes are provided on the gutter assembly 40 and the roof panel 30 for use with the rivet bolts 221. The rivet bolts 221 on the eaves support 20 cooperate with the pre-punched holes on the gutter assembly 40 and the roof panel 30 to achieve the positioning of the installation position of the gutter assembly 40 and the roof panel 30, so that the installation position of the gutter assembly 40 and the roof panel 30 is accurate, and the components of the roof eaves structure are interlocked, and the structures are pressed and fixed, so as to avoid the loosening of the connection structure between the gutter assembly 40 and the roof panel 30, and the resulting wind damage, thereby greatly improving the overall wind resistance performance.

[0099] Step S103 : fixing the third connection portion 41 of the gutter assembly 40 to the wall panel 100 .

[0100] The third connection part 41 of the gutter assembly 40 is fixedly connected to the wall panel 100, for example, it can be connected by a flat head self-tapping screw or a wall structure nail. Alternatively, the third connection part 41 of the gutter assembly 40 and the wall panel 100 are both fixedly connected to the wall purlin 101, and the third connection part 41 can be connected between the wall purlin 101 and the wall panel 100. After installation, a plug can be set in the nail hole on the wall panel 100. The plug can be used to prevent the nail head from being exposed, prevent corrosion, and be beautiful while performing waterproof treatment.

[0101] In order to further improve the bending rigidity of the eaves support member 20, in step S102, the first support portion 12 of the roof purlin 10 is connected to the second connection portion 21 of the eaves support member 20, before that, the method further includes:

[0102] A reinforcing fold 223 is provided at the second support portion 22 of the eave support member 20, and the reinforcing fold 223 is bent away from the roof panel 30. For example, the reinforcing fold 223 and the second support portion 22 form an angle of approximately 90°, and the reinforcing fold 223 forms a stiffening rib of the second support portion 22 to improve the bending rigidity of the eave support member 20. Furthermore, in order to improve the bending rigidity of the second connection, in the embodiment of the present invention, a bending structure 211 is provided at the second connection portion 21 of the eave support member 20, and the bending structure 211 is bent away from the roof panel 30.

[0103] A plurality of rivet bolts 221 are arranged near the reinforcing fold 223 of the second support part 22. The rivet bolts 221 can be 304 stainless steel M6 flat head bolts, which are arranged on the second support part 22 by rivet. The rivet bolts 221 can be produced in the factory in advance and then taken to the construction site for use, which is convenient to use. In order to match the rivet bolts 221, a plurality of pre-punched holes are arranged at positions corresponding to the plurality of rivet bolts 221 on the roof panel 30, and the spacing between the plurality of rivet bolts 221 is consistent with the spacing between the plurality of pre-punched holes on the roof panel 30. A plurality of connection holes are arranged at intervals on the second connection part 21 on the eaves support 20, and the spacing between the plurality of connection holes is 300mm and the diameter is φ6.

[0104] When installing the roof panel 30 , the first connecting portion 11 of the roof purlin 10 is first fixed, for example, fixed on the inner top plate 200 of the roof.

[0105] Then, use φ5.5 self-tapping screws with a spacing of 300mm to pass through the connecting holes, fix the second connecting part 21 of the eaves support member 20 on the first supporting part 12 of the roof purlin 10, and the second supporting part 22 with the reinforced folded edge 223 is cantilevered outward to support the third supporting part 42 of the gutter assembly 40 and the roof panel 30.

[0106] Then, the third support part 42 of the gutter assembly 40 is installed on the second support part 22 of the eaves support 20. For example, a pre-punched hole with a diameter of φ8 is preset on the third support part 42, and the hole spacing is the same as that of the rivet bolts 221 on the second support part 22. The pre-punched holes on the third support part 42 are fixed through the stainless steel rivet bolts 221 on the eaves support 20.

[0107] Finally, the pre-punched hole on the roof panel 30 is passed through the rivet bolt 221 exposed from the third support portion 42, and the nut 222 is connected to the rivet bolt 221 to complete the final installation of the roof eaves structure. The nut 222 includes but is not limited to an M6 stainless steel flange nut 222 with a locking notch.

[0108] The rivet bolts 221 on the eaves support 20 are consistent in spacing with the third support portion 42 of the gutter assembly 40 and the pre-punched holes on the roof panel 30, and act as a positioning device, so that the multiple roof panels 30 installed in the roof eaves structure are interlocked. For example, the effective width of each roof panel 30 can be controlled at 468 mm.

[0109] Furthermore, combined with Figure 1 and Figure 5 , see Figure 3 In S102, the second support part 22 of the eaves support member 20, the third support part 42 of the gutter assembly 40 and the roof panel 30 are stacked, and the waterproof assembly 50 is also provided between the roof panel 30 and the third support part 42. The waterproof assembly 50 can seal the gap between the roof panel 30 and the third support part 42 to prevent rainwater from entering the roof system. For example, when snow melts or heavy rain cannot be drained in time, causing the gutter assembly 40 in the roof eaves structure to overflow, the waterproof assembly 50 can prevent rainwater from flowing back from the gap between the roof panel 30 and the third support part 42 to cause roof leakage.

[0110] Furthermore, in order to avoid the situation that the cross-sectional shape of the roof panel is easily deformed due to its own low rigidity. In step S102, each rivet bolt 221 is connected with a nut 222, and before that, it also includes: a reinforcing strip 60 is sleeved on the rivet bolt 221, and the reinforcing strip 60 is connected to the roof panel 30 through the nut 222. When installing the roof panel 30, after the roof panel 30 is rivet on the rivet bolt 221, the reinforcing strip 60 is sleeved on the rivet bolt 221 and pressed on the surface of the roof panel 30, and finally tightened and fixed with the nut 222. The stacked structure formed by the roof panel 30, the waterproof component 50, the third support part 42 of the gutter component 40 and the eaves support member 20 can be compressed and fixed by the reinforcing strip 60 to ensure absolute density. At the same time, the reinforcing strip 60 extends along the width direction of the roof panel 30, and can be used as a stiffening rib in the width direction of the roof panel 30 to increase the wind resistance and bending stiffness of the roof panel 30.
