Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 3, a BIPV system includes a profiled metal roof 1 and a photovoltaic panel 2 disposed on the profiled metal roof 1. The profiled metal roof 1 is provided with supporting ribs 3 arranged at intervals, and the photovoltaic panel 2 is fixed on the supporting ribs 3 through frame fasteners 4.

As shown in fig. 1 and 2, the bezel fastening member 4 specifically includes a bezel main body 41 and lugs 42 provided on both end portions of the bezel main body 41. Wherein, the frame body 41 is provided with a fastening slot 411, and the fastening slot 411 is used for the end of the photovoltaic panel 2 to extend into, that is, when fixing the photovoltaic panel 2, two oppositely arranged frame fasteners 4 are needed to fix two ends of the photovoltaic panel 2 respectively; in addition, a row of fastening holes 4111 is formed in the upper groove wall of the fastening groove 411, and the fastening holes 4111 are used for fastening members to extend into the fastening grooves to fix the photovoltaic panel 2. The two lugs 42 of the frame fastening 4 are intended to be nested on adjacent support ribs 3 in order to fasten the frame fastening 4 with the photovoltaic panel 2 clamped thereto on the profiled metal roof 1.

In order to connect two adjacent frame fasteners 4 in the length direction of the frame main body 41 together, the positions of the support lugs 42 on the two adjacent frame fasteners 4 are arranged differently. In this embodiment, the bezel fastening member 4 includes two types, i.e., a first fastening bezel 100 and a second fastening bezel 200. Wherein, the journal stirrup 42 of the first fastening frame 100 is close to the side of the slot 411, and the journal stirrup 42 of the second fastening frame 200 deviates from the side of the slot 411, and when the two are fixed, the journal stirrups 42 on the two are just opposite and attached.

In this embodiment, the support lug 42 is specifically embedded in the support rib 3 through the outer limit ring 421 arranged on the support lug, and a gap is left at the bottom of the outer limit ring 421, so that the support lug 42 can be conveniently pushed into the support rib 3 to complete the embedding. Wherein, the diameter of the outer spacing ring 421 is slightly larger than the diameter of the top section of the supporting rib 3.

In order to ensure that the frame fastener 4 is locked on the supporting rib 3, the support lug 42 extends out of the boss 43 along the direction opposite to the support lug 42, the boss 43 is attached to the frame main body 41, the boss 43 is provided with an inner limiting ring 431 which has a common curved surface with the outer limiting ring 421, and the arc length of the inner limiting ring 431 is smaller than that of a semicircle of the ring where the inner limiting ring 431 is located. Like this, when two adjacent frame fasteners 4 are connected, the interior spacing ring 431 of both sides just will support the rib 3 and hold tightly, realize locking. In order to increase the friction with the support ribs 3, a flexible stop 44 is attached to the co-curved surface of the outer stop ring 421 and the inner stop ring 431. During specific atress, the inside on left side fastening frame right side, outer spacing ring and flexible stopper 44 can give and support 3 extrusion forces of rib right of rib, the left inside of right fastening frame, outer spacing ring and flexible stopper 44 can give and support 3 extrusion forces of rib left of rib, because interior spacing ring 431 on left side fastening frame right side and the left interior spacing ring 431 of right fastening frame are in same straight line, so support the extrusion force that rib 3 can receive two directions on the same straight line here, in addition flexible stopper 44's frictional force, make fastening frame and the spacing locking of support rib 3, the atress condition is as shown in figure 4.

In this embodiment, the two adjacent frame fasteners 4 are connected by a connecting structure disposed on the opposite support lug 42; specifically, the connecting structure is two fixing plates 45 correspondingly arranged on the opposite lugs 42, and the two fixing plates 45 are fixed through bolts 46.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
