[0002] Building roof wind-resistant supports are key components to ensure the safety and stability of building structures under wind loads.

[0003] The building roof wind-resistant bearing serves as the connection basis between the metal roof panel and the main structure, and directly affects the wind-resistant ability of the roof system. The traditional stamped bearing is limited by the single-layer steel plate structure, has insufficient bending section modulus, and lacks an effective lateral restraint mechanism. It is prone to instability and failure under the action of dynamic wind pressure. The stress concentration at the connection node leads to local plastic deformation. Its exposed installation causes the metal parts to be directly exposed to the corrosive environment, affecting its durability. The bearing requires multi-component assembly, resulting in low efficiency.

The U-shaped support is manufactured through an integral stamping and folding molding process. The double-standing edge inward-folded reinforcement ribs eliminate lateral instability, and the plate surface incision realizes embedded shear fixation of the roof panel, eliminating external corrosion, thereby solving the problems of low strength and external corrosion of traditional wind-resistant devices.

The cross seat 22 is used to enhance the strength of the bottom plate 11 and prevent the bottom plate 11 from being subjected to excessive force, which may cause the bottom plate 11 to bend.

[0032] A first mounting seat 23 is mounted on the top of the cross seat 22 and is used to mount the support unit 3; The support plate 24 is fixedly connected to the bottom end of the first mounting seat 23. The support plate 24 is inserted between the first reinforcing rib 13 and the second reinforcing rib 14. The thickness of the support plate 24 is 2 to 3 mm, and it fits the gap formed by the first reinforcing rib 13 and the second reinforcing rib 14 with a fitting tolerance of ±0.5 mm.

The support plate 24 is located between the two double vertical edge plates 12. The support plate 24 is used to increase the strength of the double vertical edge plates 12 and prevent the double vertical edge plates 12 from bending.

[0034] The mounting frame 21 is provided with a second mounting hole 211 , which is arranged corresponding to the first mounting hole 19 . The second mounting hole 211 cooperates with the first mounting hole 19 to mount the mounting frame 21 and the U-shaped support 1 .

[0035] Furthermore, by docking the mounting frame 21 with the base plate 11, the second mounting hole 211 and the first mounting hole 19 are used to install the mounting unit 2 and the U-shaped support 1 through self-tapping screws, and at the same time, the mounting unit 2 and the U-shaped support 1 are fixed to the building base.

[0036] According to the attached Figure 1 and Figure 8 As shown, a support unit 3 is mounted on the first mounting base 23, and the support unit 3 includes: A second mounting seat 31, which is mounted on the first mounting seat 23; A support frame 32 is provided on the second mounting base 31; Two sliders 33 slidably connected to the inner wall of the support frame 32 ; The connecting frame 34 is mounted on the two sliders 33 , and the sliders 33 are used to adjust the position of the connecting frame 34 on the supporting frame 32 .

[0037] It should be particularly emphasized that the support unit 3 is installed on the mounting unit 2 by installing the second mounting seat 31 and the first mounting seat 23. By installing the second mounting seat 31 on the first mounting seat 23, the lateral position of the support unit 3 on the first mounting seat 23 can be adjusted, and the adjusting slider 33 slides on the support frame 32 to adjust the longitudinal position of the connecting frame 34, thereby completing the position adjustment of the plywood 4 installed on the support unit 3, which is convenient for positioning the roof panel 5 through the plywood 4.

[0042] It should be particularly emphasized that the connecting frame 34 has an inclined surface corresponding to the third mounting hole 341, which facilitates the insertion of bolts into the third mounting hole 341 and the threaded groove on the slider 33. The connecting frame 34 and the slider 33 are installed by threading the bolts into the slider 33. Furthermore, the bottom end of the bolt contacts the support frame 32, and the bolt is rotated to separate from the support frame 32, so that the slider 33 and the support frame 32 are not squeezed. At this time, the slider 33 and the connecting frame 34 can be adjusted to slide on the support frame 32, and the longitudinal position of the bonding plate 4 installed on the support unit 3 is adjusted to facilitate the corresponding setting of the bonding plate 4 and the roof panel 5 to ensure the positioning of the roof panel 5. Then, the bolt is rotated to contact the bottom of the support frame 32, so that the slider 33 is squeezed against the inner wall of the support frame 32, and then the slider 33 is fixed to the support frame 32, and then the connecting frame 34 is fixed on the support frame 32.

The pressure is controlled at 80-100 tons. ③ A multi-pass progressive bending process is used to form the first reinforcing rib 13 and the second reinforcing rib 14, with the bending angle increasing by 15° each time, ultimately forming a reinforcing rib structure perpendicular to the plate surface.

A fourth mounting hole (351) is provided on the oblique edges of the mounting plate (35), and a bonding plate (4) is mounted on the mounting plate (35) through the fourth mounting hole (351).

9. A high-strength wind-resistant roof support according to claim 8, characterized in that: The bottom end of the bonding plate (4) is bonded to the two side bevels of the mounting plate (35), the top end surface of the bonding plate (4) is bonded to the bottom of the web of the roof panel (5), the two sides of the bonding plate (4) are provided with bevels, and the bevels of the bonding plate (4) are bonded to the bevels of the bottom of the web of the roof panel (5).

10. A method for manufacturing a high-strength wind-resistant roof support, according to claim 1-9, characterized in that: The following steps are involved: S1. Laser cutting blanking: A CNC laser cutting machine is used to cut the thick steel plate to form an expanded profile with a plate surface cutout (18), and the burrs on the cutout edges are polished with a sanding machine; S2. Punching process: Punching a first mounting hole (19) on the bottom plate (11) using a hydraulic punching machine in conjunction with a multi-station die; S3. Bending forming: The CNC bending machine is used for forming in three steps: ① Fix the bottom plate (11) on the workbench of the bending machine, use the 90° V-shaped upper die to fold the double vertical edge plate (12), and maintain the pressure for 3 seconds to eliminate springback; ② Switch the R5 arc upper die to press the double reinforcing ribs (15) at the connection between the bottom plate (11) and the double vertical edge plate (12), and simultaneously form the corresponding first pressing groove (16) and second pressing groove (17); ③ A multi-pass progressive bending process is used to form the first reinforcing rib (13) and the second reinforcing rib (14), with the bending angle increasing by 15° each time, ultimately forming a reinforcing rib structure perpendicular to the plate surface.
