[0023] Working principle:

[0024] Before installation, the U-shaped transfer bracket 5 is first connected to the main steel structure 2 or the reinforcing rib plate of the main steel structure 2 by welding or fastening; when the wall panel is to be installed on site, the connecting section of the U-shaped load-bearing hanger 3 on the inner side of the UHPC outer wall 1 is first extended into the U-shaped cavity of the U-shaped transfer bracket 5. In this embodiment, the surface of the connecting section of the U-shaped load-bearing hanger 3 is provided with a downwardly opening mounting notch 8, and the connecting section of the U-shaped load-bearing hanger 3 is movably connected to the outer surface of the load-bearing bolt group 4 through the mounting notch 8. Therefore, the connecting section of the U-shaped load-bearing hanger 3 can be inserted into the outer surface of the load-bearing bolt group 4 through the mounting notch 8, and then the axial position of the U-shaped load-bearing hanger 3 on the load-bearing bolt group 4 can be adjusted by sliding, so as to realize the precise positioning and adjustment of the position of the entire UHPC outer wall 1 in the left and right directions. When the position of the UHPC outer wall 1 in the left-right direction is adjusted appropriately, the load-bearing bolt group 4 can be locked and fixed by matching with the nut to achieve the supporting effect of the U-shaped load-bearing hanger 3 in the height direction.

[0025] Afterwards, the height adjustment bolt group 7 can be rotated so that the lower end of the height adjustment bolt group 7 contacts the upper surface of the load-bearing bolt group 4, thereby adjusting the axial position of the height adjustment bolt group 7 relative to the threaded sleeve 6 to achieve micro-adjustment of the entire UHPC outer wall 1 in the height direction. This can effectively solve the problem of installation failure caused by the construction accuracy error of the main structure, improve the fault tolerance of the prefabricated UHPC outer wall 1, and bring convenience to on-site construction.

[0026] Embodiment 2, as a further preferred embodiment of embodiment 1, a bell mouth is provided at the lower end of the mounting notch 8. The bell mouth enables the connecting section of the U-shaped load-bearing hanger 3 to be guided and positioned when it is clamped to the outer surface of the load-bearing bolt group 4, so as to achieve a quick clamping effect between the connecting section of the U-shaped load-bearing hanger 3 and the load-bearing bolt group 4.

[0027] Embodiment 3, as a further preferred solution of embodiment 1, the fixed section of the U-shaped load-bearing hanger 3 is connected to the UHPC outer wall 1 through an embedded sleeve connecting assembly 9, the embedded sleeve connecting assembly 9 includes an embedded sleeve and a connecting bolt, the embedded sleeve is fixedly embedded in the UHPC outer wall 1, and a through hole is provided on the surface of the fixed section of the U-shaped load-bearing hanger 3, and the threaded end of the connecting bolt passes through the through hole and is connected to the embedded sleeve through a thread.

[0028] When producing and casting the UHPC outer wall 1, an embedded sleeve can be pre-embedded on the inner side of the UHPC outer wall 1, so that during installation, the U-shaped load-bearing hanger 3 can be effectively fixed by directly connecting the bolts and the threaded connection relationship of the embedded sleeve, thereby effectively ensuring the stability of the connection between the U-shaped load-bearing hanger 3 and the UHPC outer wall 1.

[0029] Embodiment 4, as a further preferred solution of embodiment 1, a grooved mounting plate 10 is further installed on the main steel structure 2, one end of the L-shaped transfer angle code 11 is connected to the grooved mounting plate 10 by a connecting bolt 16, one end of the U-shaped constraint hanger 12 is fixedly connected to the inner side of the UHPC outer wall 1, the other end of the U-shaped constraint hanger 12 is provided with a constraint notch 13 opening downward, and the other end of the L-shaped transfer angle code 11 is clamped in the constraint notch 13. When the wall panel is constructed and installed on site, the constraint notch 13 of the U-shaped constraint hanger 12 can be clamped with one end of the L-shaped transfer angle code 11 to achieve a constraint effect on the position of the entire UHPC outer wall 1.

[0030] In addition, in this embodiment, a left and right adjustment groove 14 is opened on the surface of the groove-type mounting plate 10, and a front and rear adjustment groove 15 is opened on the surface of one end of the L-shaped transfer angle code 11. The front and rear adjustment grooves 15 and the left and right adjustment grooves 14 are arranged perpendicular to each other, and the connecting bolts 16 pass through the front and rear adjustment grooves 15 and the left and right adjustment grooves 14 in sequence and are connected and fixed to the main steel structure 2.

[0031] Therefore, when installing the L-shaped transfer angle bracket 11, the left and right adjustment slots 14 can be used to adjust the L-shaped transfer angle bracket 11 in the left and right direction relative to the main steel structure 2, and the front and rear adjustment slots 15 can be used to adjust the L-shaped transfer angle bracket 11 in the front and rear direction relative to the main steel structure 2, so that the L-shaped transfer angle bracket 11 can be accurately positioned in the restraint notch 13 of the U-shaped restraint hanger 12. This also effectively improves the fault tolerance of the prefabricated UHPC modular exterior wall.

[0032] Embodiment 5, as a further preferred solution of embodiment 1, the U-shaped restraint hanger 12 is connected to the UHPC outer wall 1 through the embedded sleeve connection assembly 9.
