[0105] A multi-condition coupled loading test method for an outdoor work scaffold comprises the following steps: when a multi-condition coupled loading test is required on the outdoor work scaffold, seat I11, seat III51, and seat II41 are placed on the foundation surface of the test site; a first set of U-shaped ground nails are placed in receiving holes VI52 and I13; a second set of U-shaped ground nails are placed in receiving holes VII53 and IV48; the upper end face of the inclined portion of the support leg 6 is placed between the middle of the outer side face of seat I11 and the lower end face of the block 12; and the U-shaped ground nails are hammered into the foundation. Thus, the support base 1, application assembly 4, intermediate base 5, and support leg 6 are installed together on the foundation surface of the test site. The upper end surface of the horizontal part of the seat part Ⅰ11 is used as the installation foundation, and the receiving hole body Ⅱ14 is used as the installation hole body. The external working scaffolding with super strong thin-walled steel pipe is installed on the seat part Ⅰ11. The telescopic cylinder 42 is in a contracted state, and the sleeve 22 is driven to move downward on the vertical portion of the frame 44 through the beam portion I 23, so that the rope portion I 43 and the rope portion II 46 are in a taut state. The screw portion II 47 is rotated in the receiving hole body V 49, and the indicator portion 45 is set to the initial value state. Place the beam portion III 31 on the loading area of ​​the external working scaffold, place the screw portion I 34 into the receiving hole III 25, and rotate the nut portion 33 on the screw portion I 34 so that the inner end surface edges of the disc portion 32 and the inner end surface edges of the nut portion 33 act on the plate portion 21 respectively, thereby installing the application rod 3 between the pressure wall 2 and the external working scaffold.

The pull rope is connected to the displacement measurement part of the external working scaffold, so that the screw portion III 82 on the displacement sensor 92 rotates in the receiving hole IX 73, so that the pull rope on the displacement sensor 92 is in a taut state, and the displacement sensor 92 is set to an initial value state. The screw portion III 82 on the pressure sensor 91 rotates in the receiving hole IX 73, so that the contact body of the pressure sensor 91 acts on the pressure measurement part of the external working scaffold, and the pressure sensor 91 is set to an initial value state.
