A docking rod 6 is fixedly connected to the top of the connecting block 2. A docking groove 7 is opened on the side of the precast member 1. The top of the docking rod 6 is inserted into the inside of the docking groove 7. The number of the docking rods 6 and the docking grooves 7 is four. After the docking rod 6 is inserted into the docking groove 7, it can also support the precast member 1 and improve the stability of the precast member 1. An installation mechanism 8 is arranged at the bottom of the precast member 1. The installation mechanism 8 includes an L-shaped plate 81, an embedded part 82, a gasket 83, and a nut 84. The L-shaped plate 81 is fixedly installed at the bottom of the precast member 1. The embedded part 82 is fixedly connected to the top of the connecting block 2 and passes through the L-shaped plate 81 to be movably connected to the L-shaped plate 81. The embedded part 82 is pre-embedded during the casting of the connecting block 2. The gasket 83 is movably sleeved on the embedded part 82. The nut 84 is threadedly connected to the embedded part 82 and abuts against the gasket 83. An inclined rod 811 is fixedly connected inside the L-shaped plate 81. By setting the inclined rod 811, the strength of the L-shaped plate 81 can be improved. The number of the inclined rods 811 is multiple and they are equidistantly distributed. A slot 3 is opened on the top of the connecting block 2. A support plate 4 is fixedly connected to the bottom of the precast member 1, and the bottom of the support plate 4 is inserted into the inside of the slot 3. The number of the support plates 4 and the slots 3 is two. The bottom size of the support plate 4 matches the size of the slot 3, so that the support plate 4 is stably inserted into the slot 3. A triangular plate 5 is fixedly connected between the support plate 4 and the precast member 1. By setting the triangular plate 5, the strength of the support plate 4 for supporting the precast member 1 can be improved. The number of the triangular plates 5 is multiple and they are equidistantly arranged.

[0022] In this embodiment, after aligning the docking groove 7 with the docking rod 6, releasing the precast member 1 allows the top of the docking rod 6 to be inserted into the docking groove 7, and the bottom of the support plate 4 is automatically inserted into the interior of the slot 3, thus quickly completing the preliminary positioning and installation of the precast member 1. The operation is simple and convenient, improving the installation efficiency. After aligning the docking rod 6 and the docking groove 7, the embedded part 82 on the connecting block 2 will automatically pass through the L-shaped plate 81, then a gasket 83 is sleeved, and the nut 84 is tightened to complete the installation of the precast member 1. The setting of the two L-shaped plates 81 improves the installation stability, and a plurality of gaskets 83 and nuts 84 are equidistantly distributed on each L-shaped plate 81, and the two, supplemented by a plurality of embedded parts 82, further improve the firmness of the installation.
