(2) The second mode of direct splicing of the traditional modularized prefabricating units adopts full prefabricating wall modules to be arranged back to back, a double-layer wall body is formed between each two modules, and the double-layer wall body cannot resist side force integrally, so that the thickness of the double-layer wall body is often too thick, and the effective use space of the building is also "occupied".
(3) When the hydropower pipeline is buried in the prefabricated modules in a direct splicing mode of the traditional modularized prefabricated units, gaps are hardly reserved between the modules, and the on-site pipeline is difficult to butt joint.
(4) The roof of traditional module unit adopts steel bar truss superimposed sheet, realizes the connection of each module roof of floor through post-cast superimposed layer concrete. On one hand, the top plate and the side wall are required to be prefabricated and assembled respectively in the production process of the modularized units, the production period is longer, and on the other hand, the maintenance time after the concrete pouring of the site floor slab also limits the further improvement of the installation speed.
(5) The traditional Chinese patent application with the application number of 2017106362012. X discloses an anti-seismic prefabricated floor slab and an anti-seismic splicing structure of the floor slab, wherein four sides of the prefabricated slab are completely connected by adopting butt dovetails, although effective transmission of forces in a plane of the floor slab can be ensured, effective connection measures of the floor slab and a wall body are not considered, when butt joints are arranged on four sides of the prefabricated slab with larger size, corners of the prefabricated slab are difficult to accurately position due to production and installation errors, and sometimes even partial dovetails need to be manually cut off for installation.
