Description
Technical Field

Background
Along with the popularization of the fabricated building, the prefabricated hollow wallboard of the concrete shear wall structure is gradually and widely applied, and in the industrialized construction mode, the large-area common wall body, the corners and the wall body provided with doors and windows are assembled by adopting prefabricated parts. Especially, the wallboard prefabricated component for installing doors and windows has high strength requirement of a connecting structure and complex installation and construction procedures.
As disclosed in CN201611181495.8 by the inventors, a concrete prefabricated wall panel and an assembled building and construction method thereof, wherein the construction method of the assembled building comprises the following steps: firstly, placing longitudinal steel bars; (2) placing a first wall panel; (3) Placing horizontal steel bars in the non-through transverse holes of the first wallboard; (4) Placing a second wallboard adjacent to the first wallboard; (5) Stirring the horizontal steel bars in the transverse holes to the direction of the second wallboard so that part of the horizontal steel bars extend into the transverse holes of the second wallboard; and (6) pouring concrete in all the holes.
The installation method of the step (1) and the step (2) is a process commonly adopted in the prior art at present, namely, longitudinal steel bars (namely, vertical steel bars) are installed in advance, then the wallboard is lifted by using lifting equipment and placed downwards from a high place, so that the installed longitudinal steel bars are accurately inserted into hollow holes of the wallboard. However, through a large amount of construction operations, the installation mode needs to lift the wallboard high, and when falling, constructors are required to stand under the wallboard to observe and even need manual assistance, so that all the reinforcing steel bars are ensured to be accurately inserted into the hollow holes of the wallboard. The method not only increases the personal safety risk of constructors, but also has high hoisting cost, low efficiency and long construction time. In addition, the gap between the wallboard and the floor slab is very small, and concrete poured in the later stage is difficult to flow in, so that the phenomenon of water seepage easily occurs at the wall root in the use process.
Therefore, how to improve such conventional construction methods is one of the difficulties that those skilled in the art are required to solve.
