Detailed ways

The present invention will be further described below with reference to specific embodiments, but the protection scope of the present invention is not limited thereto.

As shown in Figures 1-6, the cornice backing plate 1 in the present invention comprises a first backing board 11, a second backing board 12, a third backing board 13 and a fourth backing board 14, the first backing board 22 and the The second backing plate 23 is vertically connected, the two ends of the third backing plate 13 are respectively connected with the second backing plate 12 and the fourth backing plate 14, and the included angle between the third backing plate 13 and the second backing plate 12 is an obtuse angle, The included angle between the third pad 13 and the fourth pad 14 is an obtuse angle, and the second pad 12 and the fourth pad 14 are parallel; the second pad 12 is provided with a number of openings 15 at equal intervals , the fourth backing plate 14 is provided with a number of openings 2 16 at equal intervals, and the spacing of the second openings 16 is greater than the spacing of the openings 15.

The cornice backing plate 1 of the present invention is installed under the roof panel 2. The roof panel 2 is provided with vertical reinforcing ribs 21, wind-resistant steps 22 and umbrella-shaped locking seam structures 23, and the wind-resistant steps 22 are located at the vertical reinforcing ribs 21. On both sides, the umbrella-shaped lock seam structure 23 is 465°-495° lock seam. When the lock seam is 465°, it has strong wind resistance, and when the lock seam reaches 495°, the wind resistance is stronger. The unique umbrella-shaped lock seam structure, the strength and stiffness of the lock seam are very superior, and the anti-damage against wind test provides sufficient strength and rigidity support, and the self-locking principle of the lock seam of the present invention can better prevent the fixed seat from the lock seam. Detach and improve wind resistance.

The wave height of the roof panel 2 in the present invention is greater than 75 mm, and the longitudinal direction wave crest of the roof panel is on a straight line and the transverse direction wave crest is on a plane during pressurization. In the case of no wind clip, it can successfully pass the air pressure strength test of 105psf (5.0Kpa), which is equivalent to a typhoon of level 17.

In order to further improve the wind resistance and tensile strength, the present invention is provided with a support 3 below the umbrella-shaped lock seam structure 23 . The support 3 includes a support piece 31 , a base 32 is arranged below the support piece 31 , a connection piece 33 is arranged above the support piece 31 , a force bearing piece 34 is arranged above the connection piece 33 , and there are two force bearing pieces 34 , and The two force-receiving members 34 are respectively located on both sides of the connecting member 33 . A reinforcing piece 35 is arranged between the support piece 31 and the base 32, a transition piece 36 is arranged between the support piece 31 and the connecting piece 33, the force receiving piece 34 is perpendicular to the connecting piece 33, the connecting piece 33 is perpendicular to the transition piece 36, and the transition piece 36 is perpendicular to the support 31, and the reinforcement 35 is perpendicular to the base 32. The base 32, the reinforcing piece 35, the support piece 31, the transition piece 36, the connecting piece 33 and the force-receiving piece 34 are all integrally formed, which avoids that the joint between the sliding piece and the base in the combined support is a weak place where the force is weak and the wind pressure is high. The disadvantage of easy separation, the one-piece bearing can give full play to the tensile properties of steel (8KN).

The structure of the cornice backing plate 1 of the present invention is very favorable for bonding with the roof panel 2, and the zero gap avoids the leakage of rainwater, and finally avoids the corrosion of the roof panel 2.

The above embodiments are only used to illustrate the inventive concept of the present invention, but not to limit the protection of the rights of the present invention.
