Embodiment 3
[0041] Such as figure 1 As shown in -7, an installation method of a prefabricated pre-embedded thread transfer device is applied to the installation of the above prefabricated pre-embedded thread transfer device to realize the effective connection between support systems 6 such as hangers and structures, including the following steps:
[0042] Step 1: Combine the adapters 1, 3 of the assembled embedded thread adapter with the bases 2, 4;
[0043] Description: Insert the adapter 1 directly into the base 2 or use the matching threads of both the adapter 3 and the base 4 to turn the adapter 1 into the base.
[0044] Further, the inner threaded holes 111 , 311 of the adapters 1 , 3 are located in the vertical through holes 211 , 411 of the bases 2 , 4 .
[0045] Step 2: Fix and install the assembled pre-embedded thread adapter device on the structural formwork through the bases 2 and 4. The installation of the assembled embedded thread adapter device on the structural formwork is...
