Description

A type of roof wind-resistant clamp structure Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a roof wind-resistant clamp structure. Background Technology

[0002] With economic and social development and increasing demand, large-span structural designs are becoming increasingly common. Standing seam metal roofing systems are now widely used in large-span spatial structures. Their unique roof construction makes them extremely sensitive to wind loads. Under strong winds, they are prone to tearing and bending, or even being directly blown off by the wind and suffering wind-induced damage.

[0003] Existing studies have shown that the fixing seat is the core part that provides wind resistance, and numerous accident cause analyses have also shown that the disengagement of the fixing seat causes it to be unable to provide load-bearing capacity, resulting in large areas of the roof panels being lifted off.

[0004] In related technologies, adding wind-resistant clips can effectively improve the wind load-bearing capacity of a roof system. However, in extreme weather conditions, the wind-resistant clips may still loosen or even fall off, leading to wind uplift damage to the roof system.

[0005] Therefore, it is necessary to develop a new type of wind-resistant roof structure to improve some of the problems existing in related technologies. Summary of the Invention

[0006] The purpose of this invention is to provide a roof wind-resistant clamp structure that has better anti-loosening ability.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] The roof wind-resistant clamp structure provided by this utility model includes at least two clamping members; each clamping member includes a clamping part and an interlocking part; the clamping parts are spaced apart to form a clamping structure for fixing the locking edge of the roof panel to resist wind load; the interlocking parts are fitted together to form an interlocking structure for fixing the clamping members to each other; wherein, the interlocking structure includes a groove, a protrusion, and a blocking part; the protrusion extends into the groove to resist the vertical displacement of the roof panel; the blocking part is disposed on the opposite side of the extension direction of the protrusion to prevent the protrusion from coming out and to resist the lateral displacement of the roof panel.

[0009] Furthermore, the clamping component also includes a connecting portion, the engaging portion being located at one end of the clamping portion away from the roof panel, and the connecting portion connecting the engaging portion and the clamping portion.

[0010] Furthermore, the groove and the protrusion are respectively disposed on different clamping parts, and the connecting part connects the clamping part and the protrusion, or connects the clamping part and the groove.

[0011] Furthermore, the occlusal portion includes occlusal plates, which are disposed at certain intervals on the connecting portion to form the groove portion; the first end of the protrusion extends into the space between the occlusal plates, the occlusal plates protrude from the second end of the protrusion, and the blocking portion is disposed at the end of the occlusal plates to abut against the second end of the protrusion.

[0012] Furthermore, the end of the blocking portion extends and covers the connecting portion, forming two connecting portions and the blocking portion arranged laterally on the roof panel.

[0013] Furthermore, the roof wind-resistant clamp structure also includes fasteners that pass through the two connecting parts and the blocking part to connect the three together.

[0014] Furthermore, the roof wind-resistant clamp structure also includes a pressure bar for connecting adjacent purlins, and the clamping fastener is disposed on the pressure bar.

[0015] Furthermore, the clamping component also includes a limiting part for connecting the pressure rod, and the limiting part and the engaging part are disposed opposite to each other at both ends of the clamping part.

[0016] Furthermore, the limiting part is a bent structure, and the end of the limiting part extends and connects to the bottom of the roof pressure bar.

[0017] Furthermore, the protrusion is inserted in a direction 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 clamp structure provided by this utility model enhances the connection reliability of the clamps by forming an interlocking structure between the interlocking parts of at least two clamping members, which helps to reduce the risk of the clamping members loosening under external forces. In addition, the interlocking of the two clamping members through the groove and the protrusion can resist the vertical displacement of the roof panel. Furthermore, the blocking part on the opposite side of the insertion direction of the protrusion can prevent the protrusion from loosening after interlocking. This not only enhances the vertical interlocking reliability but also achieves lateral interlocking, which can resist the lateral displacement of the roof panel and improve the overall load-bearing capacity of the roof wind-resistant clamp.

[0020] 2. The end of the locking edge that is far from the roof panel is the area most sensitive to wind load. This utility model uses a connecting part to set the interlocking part at the end of the clamping part that is far from the roof panel, so that the interlocking structure formed by the interlocking part is close to the end of the locking edge, which is beneficial to improving the wind load resistance.

[0021] 3. This utility model uses a blocking part located at the end of the biting plate to abut against the protrusion to prevent loosening, and the end of the blocking part extends to the connecting part below the protrusion. This allows the anti-loosening ability to be enhanced not only by the abutting between the end of the protrusion and the blocking part, but also by the abutting between the connecting part and the blocking part when resisting loosening.

[0022] 4. This utility model arranges the connecting part and the blocking part in the horizontal direction of the roof panel and connects them with fasteners, so that the three parts form a rigid whole and form 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, better adapt to complex wind load changes, and thus improve the overall load-bearing capacity and stability of the wind-resistant structure.

[0023] 5. This utility model connects the pressure bar to adjacent purlins, thereby improving the overall rigidity of the roof structure. The pressure bar is connected to the limiting part, so that the pressure bar and the interlocking part are positioned opposite each other at both ends of the clamping part. This allows the bottom of the wind-resistant clamp structure to be enhanced with anti-detachment performance through the pressure bar, and the top of the wind-resistant clamp structure to be enhanced with anti-detachment performance through the interlocking structure, so that both ends can better maintain the clamping effect under wind load.

[0024] 6. By designing the limiting part as a bent structure, since the vertical deformation of the roof system is dominant, the end of the limiting part extends and connects to the bottom of the pressure bar, which helps to limit the vertical deformation of the high rib part of the roof panel and improves the overall vertical rigidity.
