[0048] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0052] Figure 1 For a schematic diagram of the structure of a metal roof provided by an embodiment of the utility model, please refer to Figure 1 .

[0053] The present embodiment provides a metal roof surface, which is laid on the top of a steel structure building to protect against rain, wind and sun. Since the roof surface area of ​​a steel structure building is relatively large, in order to facilitate manufacturing, the metal roof surface includes a plurality of roof panels 20 arranged in sequence, and the two sides of the roof panels 20 have mutually matching male vertical edges 21 and female vertical edges 21, and the female vertical edges 21 of the upstream roof panel 20 are buckled on the male vertical edges 21 of the downstream roof panel 20 to achieve the connection between two adjacent roof panels 20. Since the area of ​​the metal roof surface is relatively large, it will be easily fallen off due to wind force, so the metal roof surface is often connected to the purlin keel through a fixed bracket, thereby improving the wind resistance of the metal roof surface. The more fixed brackets there are and the denser they are arranged, the higher the connection strength between the metal roof and the purlin keel, and the less likely it is to be blown up by the wind. Therefore, multiple fixed brackets are arranged at intervals on the purlin keel, and one end of the fixed bracket is connected to the purlin keel by screws to ensure the connection strength between the fixed bracket and the purlin keel. The adjacent vertical edges 21 of two adjacent roof panels 20 that are buckled together are covered and clamped on the other end of the fixed bracket, so as to not only ensure the wind resistance of the metal roof, but also avoid drilling holes in the roof panel 20 to achieve the connection between the two adjacent roof panels 20, thereby ensuring the waterproofness of the metal roof.

[0054] It is understandable that different regions have different wind levels, and the metal roof surfaces of steel structure buildings located in different regions need to meet different wind resistance requirements. When the steel structure building is constructed in an ultra-high wind pressure area, especially in an area where the wind force reaches 14KN / ㎡ or above, the metal roof panel 20 cannot resist the effect of wind force by only relying on the clip-on method.

[0055] Figure 2 for Figure 1 For the cross-sectional view of AA, please refer to Figure 1 and Figure 2 .

[0056] In order to solve the above problems, the metal roof surface of this embodiment also includes an anti-wind-uplift component 10, which is arranged along the width direction of the roof panel 20. The anti-wind-uplift component 10 can lock the adjacent vertical edges 21 of two adjacent roof panels 20 on the fixed bracket, thereby increasing the connection strength between the two adjacent roof panels 20 and increasing the anti-wind-uplift ability of the metal roof surface. Multiple anti-wind-uplift components 10 are arranged at intervals along the length direction of the roof panel 20, so that the strength of the connection between the entire metal roof surface and the purlin keel is higher, further increasing the anti-wind-uplift ability of the metal roof surface, and meeting the anti-wind-uplift requirements in ultra-high wind areas. In addition, compared with the method of continuously increasing the density of purlin keels to increase the fixed bracket, the cost is lower.

[0057] For more information, see Figure 1 and Figure 2The anti-wind-lift assembly 10 includes a plurality of pressure piece groups 100 and a fastening group 200, wherein the pressure piece group 100 is arranged along the width direction of the roof panel 20, and the two ends of the pressure piece group 100 are respectively abutted against the vertical edges 21 of the corresponding ends, and the fastening group 200 sequentially passes through the end of the upstream pressure piece group 100, the vertical edge 21 of the upstream roof panel 20, the fixing bracket, the vertical edge 21 of the downstream roof panel 20 and the end of the downstream pressure piece group 100 to lock the adjacent ends of two adjacent pressure piece groups 100 and the adjacent vertical edges 21 of two adjacent roof panels 20 with the fixing bracket, and the plurality of pressure piece groups 100 are sequentially connected through the plurality of fastening groups 200 to connect the entire metal roof surface in the width direction to form a pressure piece combination, thereby ensuring that the entire metal roof surface can be firmly connected to the purlin keel through the fixing bracket, thereby improving the anti-wind-lift capability. Since the pressing piece group 100 spans the roof panel 20 along the width direction of the roof panel 20, and the two ends are respectively locked with the vertical edges 21 of the roof panel 20 on the corresponding sides, the pressing piece group 100 can not only strengthen the roof panel 20 at the original fixing point, that is, the connection with the fixing bracket, but also limit the bulging height when the roof panel 20 is blown by strong wind, thereby avoiding excessive deformation of the roof panel 20 and the disengagement between adjacent vertical edges 21, thereby ensuring the integrity and waterproof effect of the roof panel. In more detail, since the fixing brackets are arranged at intervals on the purlin keel, the vertical edges 21 of the part of the roof surface between two adjacent fixing brackets are limited only by the vertical edges 21 of the upstream and downstream roof surfaces interlocking with each other. In windy weather, the interlocking force is far from enough to resist the wind force, so that the vertical edges 21 of the roof surface are easily affected by the wind when not locked by the pressure piece group 100, thereby destroying the interlocking and causing disengagement. The fixing point of the pressure piece group 100 that fixes the roof panel 20 is also at the fixing bracket. When the roof panel 20 is blown to a certain height by the wind, it will be restricted by the pressure piece group 100 to avoid the vertical edges 21 of the roof surface from opening and disengaging, thereby limiting the influence of wind force on the roof panel 20. Fixing the vertical edges 21 to the fixing brackets by the pressure piece group 100 can improve the wind resistance of the roof panel 20.

[0058] For further information, please refer to Figure 2 The pressure piece groups 100 are arranged one by one with the fixing brackets, so that a plurality of pressure piece groups are arranged at intervals along the length direction of the metal roof surface to further enhance the wind resistance of the entire metal roof surface.

[0059] In order to prevent the part of the vertical edge 21 between two adjacent fixing brackets from being affected by strong wind and causing the failure of the fastening between the vertical edge 21 of the upstream or downstream roof panel 20 and the resulting opening, in some embodiments of the utility model, the wind-resistant assembly 10 also includes a locking group 300. Along the length direction of the roof panel 20, a plurality of locking groups 300 are arranged between two adjacent pressure piece groups 100 at intervals. The locking group 300 can lock the adjacent vertical edges 21 of two adjacent roof panels 20. This increases the connection strength of the part of the adjacent vertical edges 21 of two adjacent roof panels 20 between two adjacent fixing brackets, avoids the occurrence of openings due to the influence of strong wind, thereby reducing the influence of wind on the metal roof surface, preventing the metal roof surface from being blown up by the wind, and improving the wind-resistant ability of the metal roof surface.

[0060] Figure 3 A schematic diagram of the structure of a pressure piece group is provided for an embodiment of the utility model. Figure 4 for Figure 2 The enlarged view of point B in the figure, please combine Figure 3 and Figure 4 , the pressure piece group 100 is described in detail.

[0061] In some embodiments of the present invention, a feasible structure of the pressure piece group 100 is that the pressure piece group 100 includes a pressure rod 110 and a connecting piece 120. The pressure rod 110 matches the width of the roof panel 20, thereby ensuring that the pressure piece group 100 can span the entire width of the roof panel 20 to achieve the limitation of the central part of the roof panel 20. The two ends of the pressure rod 110 are respectively connected to a connecting piece 120. The two connecting pieces 120 are arranged opposite to each other, and the connecting pieces 120 are abutted against the vertical edge 21. The length of the pressure rod 110 is adjustable to meet the different width requirements of the roof panel 20, so that the pressure piece group 100 can be applied to the roofs of more steel structure buildings. Specifically, the length of the pressure rod 110 can be cut according to the width of the roof panel 20 to adapt to the roof panels 20 of different metal roof surfaces, for example Figure 5 The width of the roof panel 20 is 300 mm, the height of the vertical edge 21 is 65 mm, and the length of the compression rod 110 can be cut to 290 mm. During installation, a 5 mm installation error is left on the left and right sides of the compression rod 110.

[0062] Due to the limited bearing capacity of the metal roof surface, in order to reduce the pressure on the metal roof surface, there is a certain distance between the compression rod 110 and the central part of the roof panel 20, and the weight of the compression rod 110 is transferred to the fixed bracket through the fastening group 200, so that the purlin keel bears the weight of the compression rod 110 through the fixed bracket, and the metal roof surface is prevented from directly bearing the weight of the compression rod 110. In addition, when the vertical edges of the roof panel 20 are locked on both sides, its own rigidity has a certain wind resistance. The gap can prevent the compression rod 110 from participating in the wind resistance when the wind force is small, thereby reducing the deformation degree of the compression rod 110. In addition, the setting of the spacing can also ensure that the compression rod 110 will not block the drainage channel, and the rainwater falling on the metal roof surface can be discharged in time when it rains. In addition, when it snows, the snow falling on the top surface of the metal roof can be blocked by the compression rod 110. At this time, the compression rod 110 is equivalent to a snow blocking rod, which can prevent snow blocks from sliding down and injuring people.

[0063] Since the strength of the top purlin keel is weaker than the bearing strength of the purlin keel on the surrounding side of the steel structure building, the compression rod 110 will not be too heavy, that is, the volume and material thickness of the compression rod 110 will not be too large, which will limit the strength of the compression rod 110.

[0064] In order to ensure that the pressure rod 110 has sufficient rigidity under the premise of being as light as possible, in some embodiments of the present invention, the pressure rod 110 is made of aluminum alloy, which is not only light in weight but also can effectively avoid air corrosion, thereby ensuring the service life of the pressure rod 110. At the same time, in some embodiments of the present invention, please refer to Figure 3 A feasible structure of the compression rod 110 is that the compression rod 110 includes a compression panel 111 and a reinforcement edge 112, wherein the length of the compression panel 111 is adapted to the width of the roof panel 20, the connector 120 is connected to both ends of the compression panel 111, and both sides of the compression panel 111 have a reinforcement edge 112, and the reinforcement edge 112 is located on the side of the compression panel 111 away from the roof panel 20. The reinforcement edge 112 can strengthen the strength of the compression rod 110. In order to prevent rain and snow from falling and being stored on the compression panel 111 between the two reinforcement edges 112, as an optional solution, the compression panel 111 has a transparent drainage hole 1111 to facilitate liquid outflow. Furthermore, there is a drainage hole 1111 at each end of the compression panel 111, which can not only speed up the liquid discharge speed, but also ensure that the liquid accumulated on the compression rod is discharged in time even if the compression rod is slightly tilted during installation.

[0065] Further, in order to ensure the installation of the pressure rod 110, please refer to Figure 3 and Figure 4 The vertical edges 21 are all arranged along the direction of the compression rod 110 away from the roof panel 20, so as to avoid the compression rod 110 from abutting or interfering with the roof panel 20 and damaging the roof panel 20. In addition, it can also serve as a limit for the installation of the connecting piece 120.

[0066] Please refer to Figure 3 Since the compression rod 110 is parallel to the central part of the roof panel 20 and the vertical edge 21 is perpendicular to the central part of the roof panel 20, the compression rod 110 is perpendicular to the vertical edge 21. Therefore, the connector 120 for locking the compression rod 110 and the vertical edge 21 on the fixing bracket is in an "L" shape. Therefore, the connector 120 includes a locking portion 122 and a fitting portion 121 connected vertically at the ends. The locking portion 122 fits the vertical edge 21. The locking portion 122 has a through hole 1221. The fastening group 200 passes through the through hole 1221 to fix the end of the compression rod 110 on the fixing bracket. The fitting portion 121 is fixed to the fixing bracket. 21 is fitted with the pressure rod 110, and the fitting part 121 can be connected with the pressure rod 110 by welding. However, considering the error during welding, in order to avoid the relative movement of the fitting part 121 and the pressure rod 110 before or during welding, in some embodiments of the utility model, the fitting part 121 has a mounting hole, and the two ends of the corresponding pressure rod 110 are also provided with through holes matching the mounting holes. When the connector 120 is connected with the pressure rod 110, the mounting hole and the through hole are aligned with the coaxial center, and the connector 120 is locked to the end of the pressure rod 110 with bolts and nuts. The mounting hole and the through hole form a fool-proof structure, which limits the position of the connector 120 on the pressure rod 110, thereby ensuring the installation accuracy between the connector 120 and the pressure rod 110, that is, after the fitting part 121 is connected with the pressure rod 110, the locking part 122 can be accurately fitted with the vertical edge 21.

[0067] For further information, please refer to Figure 3 At least two mounting holes are arranged at intervals on the fitting portion 121, and the through holes and the mounting holes are opened on the pressure rod 110 in a one-to-one correspondence, which can further limit the position of the connecting member 120, prevent the connecting member 120 from rotating, ensure the installation accuracy of the connecting member 120, and the subsequent fitting with the vertical edge 21. In this embodiment, there are two mounting holes, which can not only limit the position of the connecting member 120 but also avoid using too many bolts and nuts, reduce the difficulty of assembly, and reduce costs.

[0068] In order to reduce the difficulty of installing the pressing piece group 100 on the metal roof surface, the pressing piece group 100 can be pre-assembled before leaving the factory to avoid on-site assembly and reduce the labor intensity of operators.

[0069] It is understandable that since the wind-resistant uplift assembly 10 acts on the vertical edge 21, it has no effect on the central part of the roof panel 20, and the vertical edge 21 extends upward, so the waterproofing of the entire metal roof surface is less affected. In order to improve the waterproofing ability of the entire roof surface, in some embodiments of the present invention, please refer to Figure 4The pressure piece assembly 100 further includes a waterproof gasket 130, which can not only buffer the pressure of the locking portion 122 on the vertical edge 21 to prevent the vertical edge 21 from being crushed, but also prevent water. Further, the waterproof gasket 130 is a rubber and metal composite gasket, and the waterproof gasket 130 is arranged around the circumference of the penetration hole 1221.

[0070] Next, combine Figure 4 , the fastening group 200 is described in detail.

[0071] Please refer to Figure 4 In some embodiments of the utility model, a structure that can be realized of the fastening group 200 is that the fastening group 200 includes a penetration piece 210, a fastener 220 and a flat gasket 230, wherein one end of the penetration piece 210 is a head end 211, and the other end is a penetration rod 212, the diameter of the head end 211 is larger than the diameter of the penetration rod 212, the penetration rod 212 passes through the adjacent ends of two adjacent pressure piece groups 100 and the adjacent vertical edges 21 of two adjacent roof panels 20 and a fixed bracket, the head end 211 is limited to the outside of the end of the upstream pressure piece group 100, the penetration rod 212 has a thread, and the fastener 220 has an internal thread that engages with the penetration rod 212, so that the fastener 220 can be screwed on the penetration rod 212 and abut against the end of the downstream pressure piece group 100, thereby realizing that the adjacent vertical edges 21 and the ends of the adjacent pressure piece group 100 are locked on the fixed bracket. In order to protect the fastening group 200 and the pressure piece group 100 from damaging the coating on the outer surface during connection and ensure good corrosion resistance, the fastening group 200 also includes a flat gasket 230, and a flat gasket 230 is provided between the head end 211 and the end of the upstream pressure piece group 100 and between the fastener 220 and the end of the downstream pressure piece group 100. The flat gasket 230 can also adjust the gap, defect or deviation caused by the uneven installation surface to improve the tightness of the connection. In addition, it can also disperse the stress caused by the fastening to ensure that the fastening group 200 and the pressure piece group 100 are not damaged during connection. In addition, the flat gasket 230 can also increase the connection area and improve the friction coefficient to prevent the fastening group 200 from loosening and ensure the reliability of the connection locking. As an optional solution, the piercing member 210 and the fastener 220 can be a common bolt and nut combination, or a tension bolt and nut combination, which has a good effect of bearing side pressure.

[0072] For further information, please refer to Figure 4 In order to further prevent the fastening group 200 from loosening and ensure the stability of the connection of the pressure piece group 100, in some embodiments of the present invention, the fastening group 200 also includes an elastic gasket, which is located between the locking portion 122 and the fastener 220. After the fastener 220 is tightened, a force is applied to the fastener 220 and the locking portion 122 to increase the friction between the locking portion 122 and the fastener 220 to prevent the fastener 220 from loosening.

[0073] Figure 6 for Figure 1 The cross-sectional view at CC in the middle, then combined with Figure 6 , the locking group 300 is described in detail.

[0074] Please refer to Figure 6 Since the locking group 300 is only used to lock the adjacent vertical edges 21 of two adjacent roof panels 20, the locking group 300 can be a common bolt and nut combination, or a tension bolt and nut. There are waterproof gaskets 130 between the bolts and the vertical edges 21 and between the nuts and the vertical edges 21 to improve the waterproof ability of the metal roof. As an optional solution, there is also an elastic gasket between the nuts and the vertical edges 21 to prevent the nuts from loosening, so as to ensure the reliability of locking the adjacent vertical edges 21 of the two adjacent roof panels 20.

Figure 8 A schematic diagram of the structure of punching holes in a metal roof surface at the location where the locking group is installed, provided in one embodiment of the utility model.

[0076] Please refer to Figure 7 and Figure 8 Some steel structure buildings have been built. In order to increase the wind-resistant ability of the metal roof, an anti-wind-resistant component 10 is added. At this time, when installing the anti-wind-resistant component 10, a hole can be directly punched at the fixed bracket to allow the fastening group 200 to pass through. For steel structure buildings under construction, holes can be punched at the fixed bracket and the vertical edge 21 of the roof panel 20 before leaving the factory to increase the assembly speed at the subsequent construction site. Or because the fixed bracket is a standard part, before the anti-wind-resistant component 10 is installed, multiple roof panels 20 can be snapped and covered on the corresponding fixed bracket in sequence, and then a through hole 101 can be punched at the fixed bracket. One punching can achieve the hole opening work on three parts, and because the holes on different parts are opened coaxially, there will be no assembly error, which reduces the difficulty of assembly. Similarly, before the anti-wind-resistant component 10 is installed, multiple roof panels 20 are snapped and covered on the corresponding fixed bracket in sequence, and multiple through holes 301 are punched between two adjacent fixed brackets to facilitate the assembly of the locking group 300.

[0077] In order to reduce the danger of workers working at heights, the metal roof can be assembled in the factory and transported to the construction site for direct lifting, which not only ensures a high safety factor for the workers, but also reduces the difficulty of assembling the metal roof.

[0078] Compared with the method of adding fixing brackets or using wind-resistant clips, the wind-resistant uplift resistance assembly 10 provided in this embodiment is used to increase the overall wind-resistant uplift resistance of the metal roof surface, which not only has higher connection strength but also lower cost.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
