The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Refer to shown in Fig. 1, Fig. 1 is the perspective view of a kind of metal roofing structure the first angle of the utility model.This metal roofing structure is mainly used in the metal Roof of large span self-support type system is installed, a kind of metal roofing structure of the utility model is the problem that solution self-drilling screw cannot penetrate main purlin and almag plate, below the composition of a kind of metal roofing structure of the utility model is described.
As depicted in figs. 1 and 2, a kind of metal roofing structure comprises the main purlin 20 being installed in agent structure 10, is installed on the base plate 30 on main purlin 20, is arranged at the U-shaped groove 40 between main purlin 20 and base plate 30 and is installed on the inferior purlin 50 on base plate 30.Shown in Fig. 4, by self-drilling screw 60, inferior purlin 50 is anchored on to base plate 30 and U-shaped groove 40.
It is the framework of 6 millimeters that main purlin 20 adopts thickness, is anchored on agent structure 10 by purlin holder connector.Be installed on the perforation magnesium-aluminum alloy plate that base plate 30 on main purlin 20 adopts 1 millimeters thick, its surface is convex-concave structure.Be installed on a few font frameworks that inferior purlin 50 on base plate 30 adopts 4 millimeters thick, inferior purlin 50 comprises two wing plates 501 that outwards turnover forms respectively in end, two wing plates 501 on inferior purlin 50 fit in base plate 30, and are arranged in the concave structure of base plate 30.
