The use method further includes step S4: after the whole installation of the stone curtain wall is completed, the scaffold body 4 is dismantled, when the scaffold body 4 is dismantled to the position of the scaffold in-situ tie device, firstly, a right-angle fastener between the second tie member 30 and the scaffold body 4 is loosened, the tension of the second tie member 30 on the scaffold body 4 is released, the subsequent dismantling is facilitated, then, the bolt connection between the first tie member 20 and the second tie member 30 is loosened, the second tie member 30 is taken down, the first tie member 20 is slowly and horizontally slid towards the left side or the right side along the transverse joint 5, the first tie member 20 is made to slide out of the clamping groove of the wall-connected embedded part 10, the first tie member 20 is taken out through the transverse joint 5, the first tie member 20 and the second tie member 30 are made to be recycled, and the material cost is further reduced; or, the second connecting rod 26 of the first tie member 20 is rotated, so that the second connecting rod 26 can be hidden inside the vertical surface of the curtain wall unit plate 3, which is convenient for the secondary utilization of the scaffold in-situ tie device.

Step S4 includes joint caulking uniformly after the whole installation of the stone curtain wall, including cleaning water, mortar, dust, etc. between the gaps of two adjacent curtain wall unit plates 3, ensuring cleanness and dryness, embedding a polyvinyl chloride foam rod with a diameter of 7mm between the gaps, then sticking protective tapes on both sides of the gaps, injecting structural sealant into the gaps to make them uniformly full, removing the redundant glue on the surface of the glue joints after the glue is solidified, making the glue joints flat and smooth and consistent in depth, finally tearing off the protective tapes and wiping off the pollutants; wherein, reserve the not gluing region of width at least 100mm respectively in first drawknot piece 20 both sides, be convenient for follow-up first drawknot piece 20 along 5 horizontal sliding of horizontal seam and take out from this, treat scaffold frame body 4, second drawknot piece 30 and first drawknot piece 20 and demolish the back in proper order, again to the above-mentioned not gluing region carry out the construction of mending glue, both accelerated the on-the-spot installation progress of stone material curtain and promoted the installation quality again.

In step S1, the installation position of the in-situ tie device of the scaffold wall-linking system is located, and the steps are as follows: and popping a horizontal line parallel to the central line of the transverse joint 5 on the building outer wall 1, determining a vertical line between two adjacent vertical rods of the scaffold 4, wherein the intersection point of the horizontal line and the vertical line is the installation position of the in-situ drawknot device, namely a new drawknot point.

In step S2, after the buckling portion 22 of the first tie member 20 is buckled to the buckle groove of the wall-connected embedded part 10, it is necessary to check whether the position of the transverse joint 5 is aligned with the first tie member 20 again, if not, the position of the transverse joint 5 is finely adjusted in the horizontal direction by using the strip hole 14 of the wall-connected embedded part 10, or the first tie member 20 buckled in the buckle groove of the wall-connected embedded part 10 is finely adjusted in the vertical direction until the position of the transverse joint 5 is aligned with the first tie member 20, and then the second tie member 30 is installed, so that the first tie member 20 can horizontally penetrate through the transverse joint 5 between two adjacent curtain wall unit plates 3, thereby preventing the first tie member 20 from rubbing and colliding with the edge of the stone material at the transverse joint.

In step S2, one end of the second tie member 30 is bolted to the end of the first tie member 20 that extends to the outer side of the vertical surface of the curtain wall unit plate, and the bolt is screwed but not screwed, and after the other end of the second tie member 30 is connected and fixed to the vertical rod or/and the horizontal rod of the scaffold body 4 through the right-angle fastener, the bolt between the first tie member 20 and the second tie member 30 is screwed.

The above description is only for the purpose of describing the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention, so that any changes and modifications made by those skilled in the art according to the above disclosure are all within the scope of the appended claims.
