The invention discloses a construction method of a prefabricated wallboard. The construction method of the prefabricated wallboard comprises the following steps of 1,
numbering the prefabricated wallboard after the wallboard is prefabricated in a factory, and transporting the prefabricated wallboard to
a site; 2, checking components and confirming the number; 3, before hoisting, constructing the bottom laying position of the prefabricated wallboard; 4, hoisting and installing the prefabricated wallboard, wherein before the prefabricated wallboard is hoisted, upper and lower supporting end bases of an inclined strut are firstly installed, after the prefabricated wallboard is hoisted, the prefabricated wallboard is adjusted in position and is connected with the inclined strut to be fixed, then a
tower crane hook is unhooked, the perpendicularity of the prefabricated wallboard is adjusted, finally, the periphery of the prefabricated wallboard is sealed, and a grouting sleeve is utilized to conduct
mortar injecting. By means of the construction method of the prefabricated wallboard, a component
assembly mode is adopted, a structural wallboard is divided into multiple blocks, after being prefabricated in the factory, the prefabricated wallboard is hoisted and installed on spot, and certain construction treatment is conducted, which helps to improve the construction quality, accelerate the
engineering progress, and improve the building quality.
