Technical Field

[0001] This utility model relates to the field of building fixing technology, and in particular to a roof reinforcement structure with strong wind resistance. Background Technology

[0002] When temporary sheds need to be erected during construction, easy-to-install components such as corrugated steel roofs are often used as the roofs of the sheds. However, these roofs are easily blown off by crosswinds in windy weather, resulting in insufficient reliability.

[0003] Existing technologies, such as patent CN217871981U, often involve arranging steel cables above the corrugated steel roof and then anchoring both ends of the cables to the ground. While this method can secure the roof, its fixing structure is relatively simple and crude, and there is room for improvement. Utility Model Content

[0011] Furthermore, the longitudinal rod is provided with snap-fit ​​components at both ends, which engage with the ends of the longitudinal rod, and a slot is constructed on the side away from the longitudinal rod, which is suitable for securing with the edge of the color steel sheet.

[0025] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] See Figures 1-4 This utility model provides a technical solution:

[0027] A wind-resistant roof reinforcement structure includes two fixing frames 100 adapted to be installed on a corrugated steel sheet 400.

[0028] refer to Figure 1 The diagram shows a case where a fixing bracket 100 is installed on a color steel tile 400. It can be understood that after two fixing brackets 100 are respectively installed on both sides of the color steel tile 400 and are snapped and fixed to the color steel tile 400, the two fixing brackets 100 fix the color steel tile 400 from both sides.

[0029] Specifically, one end of the fixing frame 100 extends out to the fixing section 111 for fixing the steel cable (not shown in the figure), the other end of the steel cable is anchored to the ground, and the fixing section 111 is adapted to extend beyond the color steel tile 400.

[0030] Thus, the fixing frame 100 uses slots 31 or clamping structures that match the waveform of the corrugated steel sheet 400. During installation, workers can directly push or snap the fixing frame 100 onto the side of the corrugated steel sheet 400 before or after it is laid onto the roof structure, so that the slots 31 or clamping structures tightly engage with the crests or troughs of the corrugated steel sheet 400. Compared to conventional techniques that require workers to laboriously arrange and tension the cable network covering the entire roof after the corrugated steel sheet 400 has been laid, the structure of this embodiment allows the fixing frame 100 to be easily snapped and fixed on the ground or at a low level before the corrugated steel sheet 400 is hoisted onto the roof or during its laying. This simplifies the complexity and danger of high-altitude operations, eliminating the need for workers to walk and operate over a large area on the already laid, relatively fragile roof to install fixing rigging, significantly improving construction efficiency and safety.

[0031] Furthermore, after the two fixing frames 100 are respectively snapped and fixed to the two sides of the color steel tile 400 plate, they are respectively connected and tensioned to the ground by independent steel cables through their respective extended fixing sections 111. This double-sided fixing structure provides the horizontal constraint force lacking in the traditional single-layer steel cable pressing method. The color steel tile 400 plate is firmly clamped between the two fixing frames 100, and the fixing frames 100 themselves form a stable connection with the ground anchor point through the oblique tension of the steel cables.

[0032] Thus, when encountering strong crosswinds, the 400-panel corrugated steel sheet tends to slide horizontally across the roof frame. However, the double-sided fixing frame 100 structure in this embodiment, through its interlocking points with the 400-panel corrugated steel sheet and the laterally arranged steel cables, effectively transmits and resists this horizontal shear force, suppressing the lateral displacement of the 400-panel corrugated steel sheet under wind load. This significantly enhances the overall roof's ability to resist strong winds, making it less susceptible to being destructively torn off or displaced.

[0033] Of course, the use of the fixing frame 100 to fix the color steel tile 400 in the above embodiment is only one implementation of the strong wind-resistant roof reinforcement structure in this application. In other implementations, it is not only applicable to color steel tiles, but also to other roof structures similar to color steel tiles, such as steel bar processing sheds.

[0034] refer to Figure 2 The specific structure of the fixing frame 100 is described as shown.

[0035] The fixing frame 100 includes: horizontal bars 110 and vertical bars 120 arranged vertically and alternately, the horizontal bars 110 and vertical bars 120 being connected at the intersection. For example, the horizontal bars 110 and vertical bars 120 are bound together by short steel cables. In this way, when manufacturing the fixing frame 100, multiple vertical bars 120 can be bound together based on two horizontal bars 110 or one horizontal bar 110 with a fixing section 111, so that different numbers of vertical bars 120 can be set according to different situations.

[0036] like Figure 1 As shown, the crossbar 110 is located below the longitudinal bar 120. The crossbar 110 is adapted to be disposed in the recess of the color steel sheet 400, and the longitudinal bar 120 is adapted to be fitted onto the protruding part of the color steel sheet, which can increase the fixing effect.

[0037] In detail, the horizontal bar 110 is positioned in the recessed area (trough) of the corrugated steel sheet 400, while the vertical bar 120 is tightly fitted onto the protruding portion (peak) of the corrugated steel sheet 400. This structure significantly enhances the mechanical interlocking and frictional locking effect between the fixing frame 100 and the corrugated steel sheet 400. The horizontal bar 110, embedded in the trough, provides a direct, upward restraint, similar to a mortise and tenon joint, effectively preventing the corrugated steel sheet 400 from detaching from the fixing frame 100 under wind force. At the same time, the vertical bar 120, fitted onto the peak, applies downward pressure, further pressing the corrugated steel sheet 400 against the roof support structure.

[0038] Therefore, the structure utilizes the undulating structure of the corrugated steel sheet 400 itself. When a strong wind attempts to lift the corrugated steel sheet 400, the force is directly transmitted to the crossbar 110. Since the crossbar 110 is wedged deep in the trough, it provides a stronger support point to resist the upward lifting force. The longitudinal bar 120 presses down on the crest, which increases the effective contact area and friction between the fixing frame 100 and the corrugated steel sheet 400, greatly reducing the possibility of relative sliding between the two.

[0039] refer to Figure 2 The structure shown, where the horizontal bars 110 and vertical bars 120 are perpendicularly intersecting and bound together by short steel cables, further enhances the overall stability. This grid-like frame structure, composed of multiple intersections (binding points), effectively distributes the load, which might otherwise be concentrated at a single point, across the entire frame. When wind loads act on the corrugated steel sheet 400, the pressure is transmitted through the multiple vertical bars 120 to the multiple horizontal bars 110, and then further distributed to their respective steel cables via the fixing sections 111 on these horizontal bars 110. This method of load distribution avoids excessive local stress, making the fixing device more uniform and reliable under strong winds, and less prone to local deformation or failure.

[0040] One end of the crossbar 110 extends into the fixing section 111, which includes a body section 11 and a fixing plate 12.

[0041] The main body section 11 is integrally connected to the crossbar 110. The fixing plate 12 is disposed on the main body section 11 and has a fixing hole 21 for passing through one end of the steel cable. In this way, a bolt can be installed at the end of the steel cable passing through the fixing hole 21, so that one side of the bolt abuts against one side wall of the fixing plate 12, thereby forming a pulling force on the crossbar 110.

[0042] In some examples, continue to refer to Figure 2 As shown, the fixing hole 21 includes a first hole 211 and a second hole 212. The first hole 211 and the second hole 212 provided on the fixing plate 12 provide two threading paths for the steel cable. During installation, the end of the steel cable passes through the first hole 211 in sequence, and then through the second hole 212. This design extends the actual contact path of the steel cable on the fixing plate 12 and forms an additional bend between the two holes.

[0043] The sequential passing of the steel cable through the two holes significantly enhances the frictional locking effect between it and the fixing plate 12. As the cable passes through the first hole 211 and turns to enter the second hole 212, multiple frictional contact points are generated on the hole walls. Especially when the cable is subjected to an oblique tension from the ground anchor point, this section of the cable located between the two holes is pressed tightly against the surface of the fixing plate 12, generating significant static friction. This multi-point friction effectively prevents the cable from sliding or loosening within the fixing hole 21.

[0044] Next, refer to Figures 3-4 The snap-fit ​​structure provided on the fixing frame 100 is described in detail.

[0045] In some embodiments, the longitudinal rod 120 is provided with snap-fit ​​members 300 at both ends, the snap-fit ​​members 300 are snap-fitted with the ends of the longitudinal rod 120, and a slot 31 is formed on the side away from the longitudinal rod 120.

[0046] The slot 31 is adapted to be secured to the edge of the corrugated steel sheet 400. In this way, the user can align the fixing bracket 100 with the corrugated steel sheet 400, then align the slot 31 of the snap-fit ​​component 300 with the edge of the corrugated steel sheet 400, and finally engage the snap-fit ​​component 300 with the longitudinal rod 120. Specifically, the snap-fit ​​component 300 includes: a snap-fit ​​section 310 that engages with the longitudinal rod 120, and a first plate 321 extending from the end of the snap-fit ​​section 310 parallel to the axial direction of the longitudinal rod 120. The first plate 321 is then bent to extend into a second plate 322 and a third plate 323.

[0047] Thus, the snap-fit ​​section 310 can engage with the end of the longitudinal rod 120, and the first plate 321, the second plate 322, and the third plate 323 together define the snap-fit ​​groove 31; so that after the snap-fit ​​groove 31 aligns with the edge of the color steel tile 400, the snap-fit ​​section 310 can be engaged with the end of the longitudinal rod 120 to fix the color steel tile 400 and the longitudinal rod 120.

[0048] Working principle: The snap-fit ​​component 300 typically has a snap-fit ​​section 310 at one end (near the longitudinal bar 120), for example... Figure 3 The column structure shown or Figure 4 The through-hole structure is shown. The snap-fit ​​section 310 needs to be precisely matched with the corresponding structure pre-set at the end of the longitudinal rod 120.

[0049] During installation, the worker first aligns the snap-fit ​​interface of the snap-fit ​​part 300 with the end of the longitudinal rod 120.

[0050] Then, the entire fixing frame 100, with the still-unpressed snap-fit ​​component 300 attached, is moved onto the corrugated steel sheet 400 plate. The snap-fit ​​groove 31 is then aligned with the edge of the corrugated steel sheet, and a certain axial pressure is applied to firmly engage or lock the snap-fit ​​section 310 with the end of the longitudinal rod 120. During this process, the edge of the corrugated steel sheet 400 naturally embeds into the snap-fit ​​groove 31 of the snap-fit ​​component 300; the inner wall of the snap-fit ​​groove 31 tightly fits and snaps onto the wave-like structure of the edge of the corrugated steel sheet 400, and the shape of the snap-fit ​​groove 31 is usually designed to match the specific wave-like edge of the corrugated steel sheet 400.

[0051] In some examples, one end of the longitudinal rod 120 is provided with a boss 121, and the other end is provided with a through hole 122 adapted to mate with the boss 121. In this way, multiple longitudinal rods 120 can be sequentially mated together, and correspondingly, the snap-fit ​​section 310 includes... Figure 3 and Figure 4 The two exemplary cases shown are, in one example, the snap-fit ​​section 310 is constructed as a boss, and in the other example, it is a through hole, adapted to mate with the boss and through hole of the longitudinal bar 120.

It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
