The installation space of the composite wallboard A on the uppermost layer is insufficient, and the installation cannot be completed according to the installation mode, so that the structure and the installation mode of the wallboard A need to be adjusted for the two layers of composite wallboards A on the uppermost layer (the height dimension of the standard board is smaller than 2 times), and the method is specifically as follows:
The panel 1 of the wallboard A is fixed by four edges with the grooves 6 instead of three edges with the grooves 6, meanwhile, the profile frame 2 on the uppermost layer of the wallboard A is correspondingly adjusted to be matched with one side without the grooves 6, and the heights of the inner side panel and the outer side panel 1 are different, as shown in figure 10, the aluminum alloy profile for installing the top wallboard is used in a complete set with the standard profile, and the last wallboard at the top is not fixed in size and needs to be disassembled according to the actual height of a building, so that the flange 202 for fixing the panel is removed from the profile for the last wallboard at the top, and the wallboard with different widths can be applied, and although the panel 1 is fixed by three edges, the structural strength is not affected and the applicability is stronger;
The wall body and the main structure beam 14 are reserved with 15-25mm (such as 20mm, 21mm and 22 mm) installation gaps, the uppermost layer of wall body frame beam 8 is welded and fixed with the main structure beam 14 through a connecting plate 15, and after the installation side of the wall body frame beam 8 is blocked by the panel 1, the installation gaps are blocked by adopting a fireproof material 16;
The node installation is shown in fig. 11, the frame column 7 and the main structure beam column connection node concrete structure is characterized in that the frame column 7 is arranged at the vertical joint of two adjacent wallboards A, the top of the frame column 7 is connected with the embedded steel plate 13 of the main structure frame column 17 through a connecting steel plate 11, the bottom of the frame column 7 is sealed with the two adjacent wallboards A through weather-proof sealant 12, the composite wallboard A is connected with the main structure beam column and the short column 9 concrete structure is shown in fig. 12, the short column 9 is arranged at the vertical joint of the two adjacent wallboards A, the bottom of the short column 9 is sealed with the two adjacent wallboards A through weather-proof sealant 12, the yin-yang angle connection node concrete structure is shown in fig. 13, the two wallboards A are mutually perpendicular, the vertical wallboards A and the horizontal wallboards A are all provided with grooves 6 at four sides, the length of the outer side panel 1 is longer than the length of the inner side panel 1, the frame column 7 at the bottom of the vertical wallboard A is connected with the frame column 7 at the end of the horizontal wallboard A through the connecting steel plate 11, the top of the frame column 7 at the end of the horizontal wallboard A is connected with the embedded steel plate 13 of the main structure frame column 17 through the connecting steel plate 11, the outer side panel 1 is connected with the outer side panel 1 through weather-proof sealant 1, the weather-proof sealant is finished at the end of the outer side panel 1.
The above embodiments are merely examples of the present invention, and the scope of the present invention is not limited to the above embodiments, and any suitable changes or modifications made by those skilled in the art, which are consistent with the claims of the present invention, shall fall within the scope of the present invention.
