The transverse connector 500 passes through the mounting groove 330 to transversely fix the first mounting plate 310 and the prefabricated outer wall 10, and since the mounting groove 330 has a certain length in the first direction, the transverse connector 500 has a larger adjustment space in the vertical direction, and can adapt to different elevations of the prefabricated outer wall 10.
The installation and fixing process of the whole fixing structure may be such that the cast-in-place structure 20 is constructed in situ, and the first fixing part 200 and the second fixing part 400 are pre-buried on the cast-in-place structure 20. Then, the prefabricated exterior wall 10 is hoisted, and the distance between the first vertical fixing member 100 and the first fixing portion 200 in the first direction is adjusted, thereby adjusting the elevation of the prefabricated exterior wall 10. The angle code 300 is then positioned between the cast-in-place structure 20 and the prefabricated exterior wall 10. The second mounting plate 320 is then fixedly coupled to the first fixing plate 410, and the first mounting plate 310 is fixedly coupled to the prefabricated exterior wall 10 in the second direction by the transverse connector 500. Of course, the order of the fixed connection of the first mounting plate 310 and the second mounting plate 320 may be exchanged.
The above-mentioned fixing structure for the prefabricated exterior wall 10 and the cast-in-place structure 20 includes the elevation adjusting assembly, the corner bracket 300, the second fixing portion 400, and the transverse connection 500. In use, the vertical elevation of the prefabricated exterior wall 10 may be adjusted by adjusting the distance of the first vertical mount 100 and the first mount 200 of the elevation adjustment assembly in a first direction. Then, the second mounting plate 320 of the corner bracket 300 is fixedly connected with the first fixing plate 410, so that vertical fixation is formed between the prefabricated outer wall 10 and the cast-in-situ structure 20, the mounting groove 330 of the first mounting plate 310 extends along the first direction, and the transverse fixation is formed between the prefabricated outer wall 10 and the cast-in-situ structure 20 through the transverse connecting piece 500 in a wide elevation range. In this way, the fixing effect between the prefabricated outer wall 10 and the cast-in-situ structure 20 is good, and the problem that the bottom of the prefabricated outer wall 10 is in a suspended state is solved by combining the diagonal bracing of the traditional outer wall.

The number of first fixing legs 420 may be 1 or more, such as 2, 3, 4. The first fixing leg 420 may be perpendicular to the second mounting plate 320, or may form an angle with the second mounting plate 320, such as 75 °,80 °, etc., so as to further increase the bonding area between the second fixing portion 400 and the cast-in-situ structure 20.
In some embodiments, referring to fig. 1-2, the first vertical fixing member 100 includes a first embedded portion 110 and a first connecting plate 120 connected to each other, the first embedded portion 110 is used for being embedded in a fixing structure, a plane of the first connecting plate 120 is perpendicular to the first direction, and the first connecting plate 120 has a second threaded hole extending therethrough along the first direction.

The second bolt 130 is engaged with the second screw hole, and the tail portion is in contact with the second fixing plate 210.
The head of the second bolt 130 is located above the first connecting plate 120, and the tail of the second bolt passes through the second threaded hole to abut against the second fixing plate 210. Thus, by screwing the second bolt 130, the distance between the first connection plate 120 and the second fixing plate 210 in the first direction, that is, the vertical elevation of the prefabricated exterior wall 10 can be adjusted by adjusting the length of the tail portion of the second bolt 130 passing through the second threaded hole.
In some embodiments, referring to fig. 1-2, the first vertical mount 100 is a steel corbel. The steel corbel is the structure commonly used in the building field, adopts the steel corbel as first vertical mounting 100, does not need the first vertical mounting 100 of customization, has saved the cost.
