Wherein, the height direction refers to the "height direction" indicated by the arrow in fig. 15, and is the same direction as the "up and down" indicated by the arrow in fig. 14; the horizontal extending direction refers to the "horizontal direction" indicated by the arrow in fig. 15. It should be noted that, prefabricated coincide wall's height H is higher, through setting up a plurality of built-in fitting group along prefabricated coincide wall's direction of height interval, on the one hand can follow a plurality of built-in fitting group's arrangement direction evenly distributed atress at prefabricated coincide wall drawing of patterns and lifting by crane the in-process, avoid stress concentration, reduce the damage to the leaf board, on the other hand also be convenient for set up a plurality of supporting sites along the direction of height in prefabricated coincide wall installation work progress for it is more reliable to the support of prefabricated coincide wall, increases the security of work progress.

Specifically, as further shown in fig. 15, four embedded parts can be arranged along the height direction of the prefabricated laminated wall, and the first embedded part 121, the second embedded part 122, the third embedded part 123 and the fourth embedded part 124 are sequentially arranged from bottom to top, so that the prefabricated laminated wall can be prevented from being damaged in the stress process. The embedded assemblies 1 in the first embedded assembly 121 and the third embedded assembly 123 are the first embedded assemblies 111, and correspondingly, the side, far away from the cavity 204, of the second blade 202 can play a role in temporary support; the embedded assemblies 1 in the second embedded assembly 122 and the fourth embedded assembly 124 are the second embedded assemblies 112, and correspondingly, no temporary support is required to be arranged on the side, away from the cavity 204, of the second blade 202. Namely, when the embedded assembly 1 needs to play a temporary supporting role, the first embedded assembly 111 is combined; when the pre-buried component 1 does not need to play a temporary supporting role, the second pre-buried component 112 is used.

Preferably, all the embedded assemblies 1 are 500-1000 mm away from the edges of the blade, so that the embedded assemblies 1 are prevented from leaning against the edges too much, and reasonable stress of the blade is ensured.
