Description

Technical Field

[0001] This utility model belongs to the technical field of roof covering layer; skylight; eaves groove; roof construction tools, and particularly relates to a roof standing seam wind-resistant system. Background Technology

[0002] Metal roofing systems refer to a type of roofing that uses metal sheets as the roofing material and combines the structural layer and waterproofing layer into one.

[0003] Standing seam roofing systems, as one of the many mature metal roofing systems, have been widely used in the construction industry. Traditional standing seam roofing systems consist of multiple adjacent standing seam roof panels that are interlocked and fixed to the roof by fixed supports. The standing seam roof panel is formed by a base plate, standing seams, male and female fasteners, and interlocked as shown in the figure. However, after multiple adjacent standing seam roof panels are interlocked, the lack of clamps for reinforcement makes it easy for the male and female fasteners to fall off from the fixed supports. This results in a low pull-out force of the roof panels relative to the fixed supports, making the entire roofing system insufficient to withstand typhoons. Therefore, various wind-resistant clamps have emerged.

[0004] Chinese patent application number 2021228010071 discloses a roof wind-resistant system, such as... Figure 1 As shown, it includes a roof panel, which is formed by multiple adjacent roof panels interlocking and fixed to the roof at the interlocking points by fixing brackets; the outer sides of the interlocking points of two adjacent roof panels are clamped and fixed by clamps; a wind-resistant strip is set between the female and male vertical sides to prevent the roof panel from warping, bending, deforming, or breaking under negative wind pressure; this utility model, through the wind-resistant strip, can compress the roof panel, preventing the roof from warping, bending, deforming, or breaking under negative wind pressure, while not affecting the roof's drainage effect, thus improving the roof panel's wind resistance and service life. The wind-resistant strips utilize a four-bar structure. When the panel is subjected to negative wind pressure, the force transmission through the four-bar structure increases the clamping force of the roof panel clamps exponentially, thereby improving the clamping force and thus enhancing the wind resistance of the roof panel. Although the wind-resistant strip structure itself alters the wind resistance, the connection between the female and male vertical edges and the clamps uses a pair of upper fixing bolts. During strong winds, the stress is concentrated at the connection between the female and male vertical edges and the clamps, making this connection prone to deformation and ultimately leading to a decrease in strength.

[0005] Therefore, a new roof standing seam wind-resistant system needs to be designed to solve the above problems. Summary of the Invention

[0006] This utility model provides a roof standing seam wind-resistant system. This system features abutment posts at both ends of the clamp. After the left and right connecting plates are installed and connected to the clamp, the abutment posts press against the edges of the left and right connecting plates, creating multi-point stress distribution between the wind-resistant strip and the clamp. This prevents stress concentration at the connection points between the left and right connecting plates and the clamp, thus preventing deformation at these connection points and improving the strength of the wind-resistant strip.

[0007] To solve the above-mentioned technical problems, this utility model provides a roof standing seam wind-resistant system, including a roof panel, fixing seats arranged longitudinally at intervals on the roof panel, a clamp located on the fixing seat, a left connecting plate and a right connecting plate located on both sides of the clamp, and a wind-resistant pressure strip arranged transversely on the roof panel and connected to the left connecting plate and the right connecting plate at both ends to form an integral whole. The left connecting plate, the clamp, and the right connecting plate are fixedly connected by a pair of upper fixing bolts. The left connecting plate and the right connecting plate each include an upper plate, a lower plate, and an arc-shaped plate arranged between the upper plate and the lower plate. The bottom of the lower plate is connected to the wind-resistant pressure strip as an integral whole. The upper plate is attached to the upper part of the clamp, and the lower plate is attached to the lower part of the clamp. The arc-shaped plate is wrapped around the arc-shaped wall of the clamp. Abutment posts are provided on both sides of the arc-shaped wall of the clamp near the edge, which abut against the side walls of the lower plate near the edge.

[0008] Furthermore, the bottom of the arc-shaped wall of the clamp is provided with a threaded hole, the upper part of the abutment post is provided with a threaded connection part that mates with the threaded hole, the lower part of the abutment post is provided with a protruding ridge for abutting against the outer wall of the left connecting plate and the right connecting plate, and a rotating nut is provided at the threaded connection part of the abutment post.

[0009] Furthermore, a groove is provided at the lower edge of the arc-shaped plate for abutting the column through which it passes.

[0010] Furthermore, a lower fixing bolt is connected between the left connecting plate, the clamp, and the right connecting plate. The lower fixing bolt is located below a pair of upper fixing bolts and in the middle of the pair of upper fixing bolts.

[0011] Furthermore, a pair of lower fixing bolts are connected between the left connecting plate, the clamp and the right connecting plate, and the pair of lower fixing bolts are arranged one-to-one below a pair of upper fixing bolts.

[0012] Furthermore, the roof panel is formed by interlocking multiple adjacent roof panels and is fixed to the roof at the interlocking points by fixing seats; the roof panel includes a base plate and female and male vertical edges respectively located at the left and right ends of the base plate. Two adjacent roof panels are formed by interlocking the corresponding female vertical edge with the corresponding male edge, and the interlocking is correspondingly set in the arc-shaped wall of the clamp.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model discloses a roof standing seam wind-resistant system. By setting abutment columns at both ends of the clamp, after the left and right connecting plates are installed in place and connected to the clamp, the abutment columns press against the edges of the left and right connecting plates at both ends, so that the wind-resistant strip and the clamp form a multi-point force, avoiding stress concentration at the connection between the left and right connecting plates and the clamp, preventing deformation at the connection between the left and right connecting plates, and improving the strength of the wind-resistant strip.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figure 2-5This is a structural diagram of a roof standing seam wind-resistant system proposed in this utility model. The roof standing seam wind-resistant system of this utility model includes a roof panel 1, fixing seats 2 longitudinally spaced on the roof panel 1, clamps 5 located on the fixing seats 2, left connecting plates 3 and right connecting plates 7 located on both sides of the clamps 5, and wind-resistant pressure strips 4 transversely arranged on the roof panel 1 and connected to the left connecting plates 3 and right connecting plates 7 at both ends to form an integral whole. The left connecting plates 3, clamps 4 and right connecting plates 7 are fixedly connected by a pair of upper fixing bolts 8. The left connecting plates 3 and right connecting plates 7 each include an upper plate, a lower plate and an arc-shaped plate 17 arranged between the upper plate and the lower plate. The bottom of the lower plate is connected to the wind-resistant pressure strip 4 as an integral whole. The upper plate is attached to the upper part of the clamps 5 and the lower plate is attached to the lower part of the clamps 5. The arc-shaped plate 17 is wrapped around the arc-shaped wall 18 of the clamps 5. The arc-shaped wall 18 of the clamps 5 is provided with abutment posts 6 near the edges on both sides of the lower plate near the edges.

[0023] In this embodiment, abutment posts 6 are provided at both ends of the clamp 5. After the left connecting plate 3 and the right connecting plate 7 are installed in place and connected to the clamp 5, the abutment posts 6 are used to press against the edges of both ends of the left connecting plate 3 and the right connecting plate 7, so that the wind-resistant pressure strip 4 and the clamp 5 form multiple points of force, avoiding stress concentration at the connection between the left and right connecting plates and the clamp, avoiding deformation at the connection between the left and right connecting plates, and improving the strength of the wind-resistant pressure strip.

[0024] In a preferred embodiment, threaded holes are provided at the bottom of the clamp 5 near the edges on both sides. A threaded connection part 12 that mates with the threaded holes is provided on the upper part of the abutment post 6. A protruding rib 11 for abutting against the outer wall of the left connecting plate 3 and the right connecting plate 7 is provided on the lower part of the abutment post 6. A rotating nut 13 is provided at the threaded connection part of the abutment post 6. In this embodiment, the abutment post 6 is installed on the clamp 5. When it is necessary to press the left connecting plate 3 and the right connecting plate 7, the nut 13 is rotated by operating a small wrench to rotate the protruding rib 11 to the position between the abutment post 6 and the left connecting plate 3 or the right connecting plate 7. This causes the abutment post 6 to generate a pressing force on the two sides of the left connecting plate 3 or the right connecting plate 7, thus preventing the force on the wind-resistant pressure strip 4 from being concentrated at the upper fixing bolt 8 when the wind is blowing.

[0025] In a preferred embodiment, the lower edge of the arc-shaped plate 17 is provided with a groove 10 for the column 6 to pass through. In this embodiment, this structure facilitates the column 6 to abut against the side walls near the edge on both sides of the lower plate.

[0026] In a preferred embodiment, a lower fixing bolt 9 is connected between the left connecting plate 3, the clamp 5, and the right connecting plate 7. The lower fixing bolt 9 is located below a pair of upper fixing bolts and in the middle of the pair of upper fixing bolts. In this embodiment, the structure increases the bolt connection point, further dispersing stress concentration and improving the strength of the wind-resistant pressure strip 4.

[0027] In a preferred embodiment, a pair of lower fixing bolts 9 are connected between the left connecting plate 3, the clamp 5 and the right connecting plate 7. The pair of lower fixing bolts 9 are arranged one-to-one below a pair of upper fixing bolts. This embodiment solves the same problem as the previous structure. By adding two lower bolt connection points, stress concentration is further dispersed, which is beneficial to improving the strength of the wind-resistant pressure strip 4.

[0028] In a preferred embodiment, the roof panel 1 is formed by interlocking multiple adjacent roof panels and is fixed to the roof by fixing seats at the interlocking points; the roof panel includes a base plate and female and male vertical edges respectively provided at the left and right ends of the base plate. Two adjacent roof panels are formed by interlocking the corresponding female vertical edge with the corresponding male vertical edge. The interlocking points are respectively set in the arc-shaped wall 18 of the clamp 5.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
