Detailed description of the invention
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
As Figure 1-4, in figure, mark 1-10 is respectively: base plate 1, vertical rib 2, pin thread 3, box 4, open slot 5, wrench 6, plate body center line 7, common reinforcing rib 8, hold 9 greatly, small end 10.
Embodiment: as shown in Figure 1, 2, in the present embodiment waist-drum-shaped metal roofing board by integrated base plate 1 with and the vertical rib 2 of both sides form, two common reinforcing ribs 8 are wherein set in order to increase the intensity of base plate 1 on base plate 1 length direction, vertical rib 2 is vertically installed in base plate 1 both sides.The free end of vertical rib 2 is bent into respectively clutch buckle, wherein the clutch buckle of an edge-on rib 2 is pin thread 3, the clutch buckle of opposite side is box 4, between two clutch buckles, form the size structure that cooperatively interacts, the size that is box 4 is greater than pin thread 3, pin thread 3 can be sleeved in box 4 and form and be fixed, and the opening direction of pin thread 3 and box 4 is all towards base plate 1.As shown in Figure 3, metal roofing board is the convex surface of curved arc shape in short transverse, and this convex surface forms base plate 1, vertical rib 2 plastic deformations by bending.
The waist-drum-shaped of the metal roofing board in the present embodiment refers to: as shown in Figure 4, it is small in ends for metal roofing board is formed, waist drum shape broad in the middle, on the length direction of base plate 1, be provided with twice open slot 5, open slot 5 is laid in the both sides of base plate 1 taking plate body center line 7 as symmetrical centre symmetry, open slot 5 has the two ends that vary in size, width of rebate is and dwindles gradually situation along the length direction of roof panel, wherein one end is large end 9, the other end is small end 10, small end 10 starts from respectively wrench 6 places, its width along the length direction (with the bearing of trend of open slot 5) of base plate 1 gradually geometric ratio amplify until identical with the width of large end 9, so, base plate 1 can the expansion to the contraction of small end 10 directions, small end 10 to large end 9 directions by the large end 9 of open slot 5, be shaped to swelling-waist shape small in ends, broad in the middle, the plate of plate both sides wrench 6 is wide to the middle gradual change amplification of plate body until identical with the width in the middle of plate body.
The present embodiment is in the specific implementation: the ratio that the plate plate wide and intermediate board body (in the plate body at plate body center line 7 places) of base plate 1 both sides wrench 6 is wide and the small end 10 of open slot 5 exist ratio corresponding with the width ratio between large end 9, be that width between small end 10 and large end 9 is than larger, cause from wrench 6 the expansion to intermediate board body less, so the wide ratio of wrench 6 and the plate of intermediate board body is also just less; Otherwise width between small end 10 and large end 9 is than less, cause from wrench 6 the expansion to intermediate board body larger, so the wide ratio of wrench 6 and the plate of intermediate board body is also just larger.
