Description

Waterproof installation structure of daylighting panel Technical Field The invention relates to the technical field of building roof components, in particular to a waterproof installation structure of a daylighting panel. Background In metal roof systems of industrial or civil buildings, in order to meet indoor lighting requirements, lighting plates are often matched with a plated metal roof plate. At present, the widely adopted installation mode in the industry is that a support is fixed on a roof purline, then a self-tapping screw is utilized to directly penetrate through a convex edge part of a lighting board to fasten the lighting board on the support, and meanwhile, a water stop adhesive tape is arranged at a transverse lap joint part of the lighting board and a metal roof board and is matched with the self-tapping screw to carry out connection sealing. Lighting panels (e.g., FRP, PC, etc.) are often more brittle and less ductile than metals in their material properties. When the self-tapping screw is directly screwed on the convex edge with concentrated stress of the daylighting panel, micro cracks and even cracks are easily generated at the periphery of the fastening point due to the installation stress or structural deformation, wind load and temperature change in the use process. The cracks enable the fastening points to be potential water leakage points, the waterproof reliability of the roof is affected, and the hidden danger of long-term water leakage exists. Therefore, the existing daylighting panel waterproof installation structure has the problem of low waterproof reliability. Disclosure of Invention The invention aims to provide a waterproof installation structure of a daylighting panel, and aims to solve the problem that the existing waterproof installation structure of the daylighting panel is low in waterproof reliability. In order to achieve the aim, the invention adopts the following technical scheme that the waterproof installation structure of the daylighting panel comprises the daylighting panel and purline hanging pieces, wherein the daylighting panel is fixedly arranged on the upper surface of purlines through the purline hanging pieces; the daylighting panel is provided with a rib, and two sides of the rib are respectively provided with an inner hanging groove; The purline pendant comprises a strip-shaped pressing plate, a pull column and a locking component, wherein two ends of the strip-shaped pressing plate are respectively clamped in an inner hanging groove of the daylighting panel, one end of the pull column penetrates through a purline mounting hole to be in threaded connection with the strip-shaped pressing plate, the other end of the pull column is in threaded connection with the locking component, and the locking component is abutted to the lower surface of the purline so as to compress the daylighting panel on the purline. Further, the long axis direction of the inner hanging groove is parallel to the long axis direction of the convex rib. Further, the locking assembly comprises an external thread sleeve and a locking nut, the external thread sleeve is sleeved on the outer side of the pull column, the locking nut is in threaded connection with the external thread sleeve, the upper end of the locking nut is abutted to the lower surface of the purline, and the lighting board is tightly pressed on the purline by screwing the locking nut. Further, a hexagon head is arranged at one end of the pull column, which is not connected with the strip-shaped pressing plate. Further, a limiting table is arranged at one end of the pull column, which is not connected with the strip-shaped pressing plate, and the diameter of the limiting table is larger than the inner diameter of the external thread sleeve. Further, a gasket is arranged between the strip-shaped pressing plate and the locking nut, and the gasket is sleeved on the outer side of the external thread sleeve. Furthermore, the clamping surface of the strip-shaped pressing plate, which is contacted with the inner hanging groove, is provided with anti-skid convex lines. Further, a thread sleeve is arranged on the strip-shaped pressing plate, a connecting thread is arranged on the pull column, and the connecting thread is in threaded connection with the thread sleeve. Further, the thread sleeve is arranged at the center of the strip-shaped pressing plate and extends out towards the purline. Furthermore, the strip-shaped pressing plate is made of high-carbon steel. The invention discloses a daylighting panel waterproof mounting structure which comprises a daylighting panel and purline hanging pieces, wherein the daylighting panel is fixedly arranged on the upper surface of purlines through the purline hanging pieces, ribs are arranged on the daylighting panel, inner hanging grooves are respectively formed in two sides of each rib, the purline hanging pieces comprise strip-shaped pressing plates, pull columns and locking components,
