Zusammenfassung: | The utility model discloses a wall panel with a convex-concave dovetail-groove type through-the-length border seam. The butt joint surface of the wall panel is provided with one or more through-the-length dovetail channel border seams. The wall panel dovetail channels filled with the butt joint master-batch have higher strength of linkage and better temperature protection and acoustic insulation effect. The utility model is characterized in that the through length of the butt joint surface of the wall panel 1 is provided with a raised butt joint edge 2 or a butt joint channel 3 fitted with the butt joint edge 2. The butt joint edge or the butt joint channel is a dovetail; the trapezoid long side of the butt joint edge is slightly shorter than the trapezoid short edge of the butt joint channel. Two seam crossings formed on the butt joint surface are provided with joggles 4 for filler. The center of the wall panel is a cavity body 5; two butt joint wall panel bodies are mutually communicated. |
