Description

Plastic steel wave board structure improvement

The improved structural structure of the plastic steel wave plate is formed by one inner tapered rib extending from one side of the long steel plate body of the plastic steel, and an outer tapered rib extending from the other side, and the outer tapered rib is combined with the outer edge of the inner tapered rib of the upper pressing buckle to achieve the overlapping combination. By.

As shown in the first figure, the conventional plastic steel wave plate 10 is mainly formed in a long slab shape in which a continuous wavy or continuous tapered shape is formed in the cross section. First, the first wave plate 10a is fixed by the screw 11, and the second wave plate 10b is tapered. The mouthpieces are overlapped and covered with each other, and the two waves 10a, 10b are screwed from the outside of the tapered mouth by screws 11. Then, the third wave plate 10c is overlapped and covered with a tapered mouth, and the two waves 10b, 10c are screwed from the outside of the tapered mouth by the screw 11, so that the combination is circulated. However, it is checked that the two waves 10 are locked from the outer edge by the screw 11, and the water leakage is easily caused by the loose rust of the screw 11, and when the two adjacent waves 10 are overlapped by a tapered mouth, The gap between the two is easy to create a gap due to deformation, and the case of water leakage is caused by strong storm and rain.

The improved plastic steel wave plate structure is extended from the side of the long steel plate body of the plastic steel into an opening to the plate body and the downward groove, and then extends upward to form a trapezoidal inner tapered rib, and the inner tapered rib extends outwardly. A fixing plate, the outer edge of the fixing plate is further convexly provided with a convex rib. The other side of the plate body protrudes upwardly from the cover portion, and then extends upwardly with a trapezoidal outer tapered rib, and the outer edge edge of the outer tapered rib extends inwardly and upwardly by a hooking portion. When the combination is carried out, the screw is inserted through the fixing plate of the first wave plate. After the first wave plate is fixed, the outer rib of the first wave plate is fastened by the outer rib of the second wave plate, and the outer rib of the second wave plate is pressed upward. When the outer edge of the tapered rib is buckled in the first wave plate, the outer side of the outer tapered rib itself expands outwardly, and then completely covers the outer edge of the inner tapered rib to generate an elastic restoration effect, so that the outer tapered rib is hooked at the hooking portion In the groove of the inner tapered rib, the lap joint is thus achieved.

Referring to the embodiment of the second embodiment, the wave board 20 is integrally formed of plastic steel, and a trapezoidal reinforcing rib 210 is protruded upward in the middle of the single-layer long plate-shaped board body 21, and one side thereof extends upward to form an opening. The plate body 21 and the downward groove 22 are then extended upwardly to form a trapezoidal inner tapered rib 23, and the outer side of the inner tapered rib 23 extends outwardly to a fixing plate 24, and the outer edge of the fixing plate 24 is convexly convex upward. The rib 25 is. On the other side of the plate body 21, a cover portion 28 is protruded upwardly with respect to the trapezoidal reinforcing rib 210, and then a trapezoidal outer tapered rib 26 is extended upward, and an outer end edge of the outer tapered rib 26 extends inwardly and upwardly. 27 people.

As shown in the third figure, in combination, the screw 200 is inserted through the fixing plate 24a of the first wave plate 20a, and the first wave plate 20a is fixed first, and then the outer wave plate 26b of the second wave plate 20b is fastened to the first wave plate 20a. The inner tapered rib 23a (please refer to the fourth and fifth figures), when the outer rib 26b of the second wave plate 20b is pressed by the outer edge of the inner tapered rib 23a of the first wave plate 20a, the outer outer rib 26b outer plate The elastic action of the self-expansion is outwardly expanded (please refer to the sixth figure), and the outer edge of the inner tapered rib 23a is completely covered to generate an elastic restoration effect, so that the outer tapered rib 26b is hooked to the inner tapered rib 23a by the hooking portion 27b. In the groove 22a (please refer to the seventh figure), so as shown in the eighth figure, the first wave plate 20a is engaged with the second wave plate 20b, and then the third wave plate 20c is engaged with the second wave plate 20b, in order. Buckle to reach the lap group Together.

In summary, in the present combination, the outer tapered rib 26b is hooked into the recess 22a of the inner tapered rib 23a by the hooking portion 27b, thereby improving the adhesion tightness and reducing the water permeability, and the outer end of the fixing plate 24 The rib 25 also has a water-blocking function, and after the lap, the fixing screw 200 can be wrapped around the wave plate 20 by the cover portion 28, and the function of reducing the water seepage rate is achieved. In the implementation, after the outer tapered rib 26b overlaps the inner tapered rib 23a, it still has to be fixed directly from the top by the conventional fixing screw, and the bottom surface of the combined construction is fixed to the bracket as shown in the ninth figure to avoid the bird. Bird invasion. In addition, the inner tapered rib 23 also needs to be provided with a general power cord, a telephone line, and the like, and is formed by a multi-pushing technique on the wave board 20 with a layer of anti-UV or fluorescent or brightening effect. Functional layer, to enhance the use of performance.
