The invention relates to a method for manufacturing a different color wave plate, in particular to a time difference between the first and second extruders for extruding plastics, respectively, to push plastics of different or the same color into the molding die, or to set up a third extruder to push out Soft plastic, and formed with a soft water stop strip on the forming wave plate, so that after the cooling molding equipment, it becomes a finished wave board, and is pulled forward by the traction device, and then cut by the cutting device to obtain the upper and lower sides. The wall is a wave board of different or the same color or structure.

The structure of the different color wave plate of the present invention is provided with different color upper and lower wall surfaces, and a connecting reinforcing rib is disposed between the upper and lower wall surfaces, and the connecting reinforcing rib has the same color as the lower wall surface, and is located on the wave board. The first and second overlapping portions are disposed on both sides, and the first and second overlapping portions have different structures, which are sufficient for the adjacent wave plates to be overlapped and joined to each other, and bolted to the steel at the peak of the wave plate by the bolting member On the shelf, as the roof or wall of a building.

According to the conventional plastic wave board, such as Taiwan's new type M319958 "Building sheet", or Taiwan's new type M329077 "double-layer hollow plastic steel heat wave board", or Taiwan's new type M323493 "combined siding", or Taiwan The new M380972 "wave plate device", or the invention of the patent No. I369435 "double-layer wave device" in Taiwan, the common feature is that the wave plate is provided with upper and lower walls, and the upper and lower walls are the same. The color, to the lap joints on both sides of the wave board, is such that one end is connected to the other end.

Thus, the common shortcoming of the prior art prior art is that the adjacent wave plates cannot be fully combined, and the problem of the detachment of the lap portion is easily caused during the construction process. Secondly, the various knowledge The prior art was made by extrusion from a single extruder. It was impossible to distinguish the upper and lower walls, and there was a lack of vividness that could not give the building roof a better visual effect.

To this end, the inventors have accumulated many years of manufacturing and design techniques related to the extrusion technology, and have studied the shortcomings of the prior art described above, and have created the case.

It is an object of the present invention to provide a plastic wave board capable of producing the same color or a different color, whereby the wave plate is formed with different or the same color above and the lower wall surface, thereby enhancing the aesthetic and practical value of the plastic wave board.

The second object of the present invention is to form a soft water stop strip at the same time when manufacturing a plastic wave board of the same color or a different color, thereby improving the water stopping effect of the plastic wave board.

Thus, after the forming wave plate is cooled and molded, the product becomes a finished wave board, and the aforementioned wave board is pulled forward for the traction device, and finally the cutting board is cut. The cutting device is cut according to the required specifications to obtain plastic wave plates with different color or structural strength on the upper and lower walls.

The structure of the different color extruding wave plate of the present invention comprises different color upper and lower wall surfaces, and connecting reinforcing ribs between the upper and lower wall surfaces, and first and second overlapping portions are arranged on both sides of the wave board, the first And the second lap joint has a different structure, which is sufficient for the adjacent wave plates to overlap each other.

The structure of the different color wave board of the invention is the second overlap of the wall below the wave board The part is provided with a soft water stop strip integrally formed, so that when the adjacent wave plates are overlapped with each other, the soft water stop strip can be combined with the water blocking groove of the first overlapping portion of the upper wall surface to prevent external Moisture creates a siphon effect by the lap joint of the wave plate, causing external moisture to enter the room.
