本发明的工作原理为：通过第一卡合部5和第二卡合部6将A板与B板进行组装，A板的宽度与B板的宽度相同，A板的厚度与B板的厚度相同，保证组装后第一混凝土面层2与第二混凝土面层8在同一水平面；第一卡合部5与第一铝合金空心板1一体成型，第二卡合部6与第二铝合金空心板7一体成型，使得A板与B板组装的组合板更牢固，不易损坏，延长使用寿命；多个A板、B板能够组装成大面积的组合板，以满足施工需求。合金板可以设置成0.5-1.2米宽，1.5-3.6米长，铝合金上下板的厚度可根据上述长宽尺寸及外荷载的大小变换，从2-10mm变化。铝合金空心板的高度可定为50-80mm，混凝土面层约30-50mm。如果A板的两边都设有第一卡合部5，B板的两边都设有第二卡合部6，多个A板、B板能够组装成更大面积的组合板。The working principle of the present invention is: board A and board B are assembled through the first engaging part 5 and the second engaging part 6, the width of board A is the same as that of board B, and the thickness of board A is the same as that of board B Same, ensure that the first concrete surface layer 2 and the second concrete surface layer 8 are on the same horizontal plane after assembly; Hollow plate 7 is integrally formed, which makes the combined plate assembled by plate A and plate B stronger, less prone to damage, and prolongs service life; multiple plates A and B can be assembled into a large-area combined plate to meet construction needs. The alloy plate can be set to be 0.5-1.2 meters wide and 1.5-3.6 meters long. The thickness of the aluminum alloy upper and lower plates can be changed from 2-10mm according to the above-mentioned length and width dimensions and the size of the external load. The height of the aluminum alloy hollow plate can be set at 50-80mm, and the concrete surface layer is about 30-50mm. If both sides of the A board are provided with the first engaging portion 5, and both sides of the B board are provided with the second engaging portion 6, multiple A boards and B boards can be assembled into a composite board with a larger area.
