Example Embodiment
[0015] The method for lifting prefabricated external wall panels of this embodiment uses the threaded holes of the lifting end of the lower prefabricated external wall panels to cooperate with flat-angle bolts to determine the elevation of the upper prefabricated external wall panels, which specifically includes the following steps:
[0016] A. Lift the lower prefabricated external wall panel to the designated position by a crane, and fix it;
[0017] B. Install flat-angle bolts in the threaded holes of the lifting end of the lower prefabricated external wall panel described in step A. In this embodiment, a total of two flat-angle bolts are installed;
[0018] C. Adjust the horizontal height of the upper end face of the flat-angle bolt, and measure it with a level to make the distance from the upper end face of the flat-angle bolt to the reference plane consistent with the predetermined elevation of the upper prefabricated external wall panel;
[0019] D. Lift the upper prefabricated e...

The invention discloses a method and structure for hoisting prefabricated external wallboards. The method for hoisting the prefabricated external wallboards aims to overcome the defects that in the prior art, in the elevation adjusting process of hoisting the prefabricated external wallboards, the prefabricated external wallboards are required to go up and go down together, due to the fact that the weight of the prefabricated external wallboards is large, going up and going down are difficult, and the construction efficiency is low. The elevation of the upper layer prefabricated external wallboard is determined by utilizing cooperation of hoisting end threaded holes of the lower layer prefabricated external wallboard and flat angle bolts. The structure for hoisting the prefabricated external wallboards is further provided and comprises the lower layer prefabricated external wallboard, the upper layer prefabricated external wallboard and the flat angle bolts, the hoisting end threaded holes are formed in the lower layer prefabricated external wallboard, the flat angle bolts are in threaded connection with the hoisting end threaded holes of the lower layer prefabricated external wallboard, the distance from the upper end faces of the flat angle bolts to a datum plane is the same as the predetermined elevation of the upper layer prefabricated external wallboard, and the bottom face of the upper layer prefabricated external wallboard is in contact connection with the upper end faces of the flat angle bolts. According to the method and structure for hoisting the prefabricated external wallboards, the adjusting process is simple and lightweight, and the method and structure for hoisting the prefabricated external wallboards is suitable for being used during hoisting of the prefabricated external wallboards.
Description
technical field [0001] The invention relates to the field of building industrialization, in particular to a method and structure for hoisting prefabricated exterior wall panels. Background technique [0002] In the process of hoisting prefabricated exterior wall panels, it is very critical to adjust the installation position. The existing level adjustment method is as described in the patent ZL201120255747.3. A special level adjustment fastener is fixedly installed on the prefabricated exterior wall panel, and the fastener and the prefabricated exterior wall panel are adjusted by rotating the adjusting bolt to adjust the height the height of. In this way, the prefabricated exterior wall panels need to be driven up and down together during the height adjustment process. Due to the heavy weight of the prefabricated exterior wall panels, it is difficult to lift and lower the construction efficiency. Contents of the invention [0003] The invention overcomes the disadvantage...
