Description

Technical Field

[0001] The invention relates to the technical field of building engineering, and in particular to a roof wind-resistant clip structure. Background Art

[0002] With the development of economy and society and the increase of demand, the design of long-span structure is becoming more and more common. Standing seam metal roof system has been widely used in long-span space structure. Its special roof structure makes it extremely sensitive to wind load effect. Under strong wind, it is easy to tear and bend first, or directly cause the panel to be lifted by wind and damaged by wind.

[0003] Existing studies have pointed out that the fixing seat is the core part that provides wind resistance. Many accident cause analyses have also shown that the disengagement of the fixing seat causes it to be unable to provide bearing capacity, resulting in a large area of ​​the roof panel being lifted up.

[0004] In the related art, the wind resistance of the roof system can be effectively improved by adding wind-resistant clips. However, in extreme weather, the wind-resistant clips may still become loose or even fall off, thus causing wind damage to the roof system.

[0005] Therefore, it is necessary to develop a new type of roof wind-resistant clip structure to improve some of the above-mentioned problems existing in the relevant technology. Summary of the invention

[0006] The object of the present invention is to provide a roof wind-resistant clip structure which has a better anti-loosening capability.

[0007] The purpose of the present invention can be achieved by the following technical solutions:

[0008] The roof wind-resistant clamp structure provided by the present invention includes at least two clamps; the clamps include a clamping portion and a bite portion; the clamping portions are arranged at intervals to form a clamping structure for fixing the locking edge portion of the roof panel to resist wind loads; the bite portions are engaged with each other to form a bite structure for fixing the clamps to each other; wherein the bite structure includes a groove portion, a protrusion portion and a blocking portion; the protrusion portion extends into the groove portion to resist the vertical displacement of the roof panel; the blocking portion is arranged on the opposite side of the extension direction of the protrusion to prevent the protrusion from falling out and resist the lateral displacement of the roof panel.

[0009] Furthermore, the clamping member further comprises a connecting portion, the engaging portion is located at an end of the clamping portion away from the roof panel, and the connecting portion connects the engaging portion and the clamping portion.

[0010] Further, the groove portion and the protrusion portion are respectively provided on different ones of the clamping members, and the connecting portion connects the clamping portion and the protrusion portion, or connects the clamping portion and the groove portion.

[0011] Further, the engaging portion includes an engaging plate, and the engaging plate is provided on the connecting portion at a certain interval to form the groove portion; the first end of the protrusion portion extends between the engaging plates, and the engaging plate protrudes from the second end of the protrusion portion, and the blocking portion is provided at the end of the engaging plate to abut against the second end of the protrusion portion.

[0012] Further, the end of the blocking portion extends and covers the connecting portion, and the two connecting portions and the blocking portion are arranged side by side in the transverse direction of the roof panel.

[0013] Further, the roof wind-resistant clip structure further includes a fastener, and the fastener passes through the two connecting portions and the blocking portion to connect the three to each other.

[0014] Further, the roof wind-resistant clip structure further includes a pressure bar for connecting adjacent purlins, and the clamping member is provided on the pressure bar.

[0015] Further, the clamping member further includes a limiting portion for connecting the pressure bar, and the limiting portion and the engaging portion are oppositely arranged at both ends of the clamping portion.

[0016] Further, the limiting portion is a bent structure, and the end of the limiting portion extends and is connected to the bottom of the roof pressure bar.

[0017] Further, the embedding direction of the protrusion portion is parallel to the roof panel.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The roof wind-resistant clip structure provided by the present invention forms an engaging structure between the engaging portions of at least two clamping members to enhance the connection reliability of the clamping members, which is beneficial to reducing the risk of loosening of the clamping members under external forces. In addition, the two clamping members are mutually engaged through the groove portion and the protrusion portion to resist the vertical displacement of the roof panel, and the blocking portion is also provided on the opposite side of the embedding direction of the protrusion portion to prevent the protrusion portion from loosening after engagement, which not only enhances the vertical engagement reliability but also realizes the lateral engagement, can resist the lateral displacement of the roof panel, and improves the comprehensive load resistance of the roof wind-resistant clip.

[0020] 2. The end of the edge-locked part away from the roof panel is the area most sensitive to wind loads. In the present invention, the engaging part is arranged at one end of the clamping part away from the roof panel through the connecting part, so that the engaging structure formed by the engaging part is close to the end of the edge-locked part, which is beneficial to improving the wind load resistance.

[0021] 3. In the present invention, the blocking part is arranged at the end of the engaging plate to abut against the protruding part to prevent loosening, and the end of the blocking part extends to the connecting part below the protruding part, so that when preventing loosening, not only can the end of the protruding part abut against the blocking part, but also the abutment between the connecting part and the blocking part can enhance the anti-loosening ability.

[0022] 4. In the present invention, the three parts of the connecting part and the blocking part are arranged side by side in the transverse direction of the roof panel, and fasteners are used to pass through the three parts for connection, so that the three parts form a rigid connection as a whole, forming a more stable structural system. By increasing the number of connecting parts and connection points, it is beneficial to disperse stress and reduce local stress concentration, and better adapt to complex wind load changes, thereby improving the overall bearing capacity and stability of the wind-resistant clip structure.

[0023] 5. In the present invention, the strut is connected to adjacent purlins, the overall rigidity of the roof structure is improved through the strut, and the strut is connected through the limiting part, so that the strut and the engaging part are relatively arranged at both ends of the clamping part, realizing that the bottom of the wind-resistant clip structure enhances the anti-detachment performance through the strut, and the top of the wind-resistant clip structure enhances the anti-detachment performance through the engaging structure, so that both ends can better maintain the clamping effect under the action of wind loads.

[0024] 6. In the present invention, by designing the limiting part as a bent structure, since the vertical deformation of the roof system is the main factor, its end extends and is connected to the bottom of the strut, which is beneficial to limiting the vertical deformation of the high rib part of the roof panel and at the same time enhancing the overall vertical rigidity.
