[0037] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0039] The general working principle is as follows: before the wall is cast and formed, a foundation is first laid on the ground, and a certain length of steel bars are reserved on the top of the foundation, and at least three steel bars are reserved along the width of the wall, and the steel bars are arranged at equal intervals. When the wall is assembled, the stretching mechanism 4 is adjusted according to the set thickness of the insulation layer, and then the graphene insulation board 1 is vertically inserted into the middle steel bar, and the steel bar is inserted from the bottom end of the graphene insulation board 1 to the inside, the graphene insulation board 1 is positioned, and the stretching mechanism 4 is controlled, and then the outer frame plate 2 and the fine steel mesh 3 are expanded outward, and then according to the set thickness of the insulation layer, the graphene insulation board 1 is vertically inserted into the middle steel bar, and the steel bar is inserted from the bottom end of the graphene insulation board 1 to the inside, and ... then the graphene insulation board 1 is positioned, and the stretching mechanism 4 is controlled, and then the outer frame plate 2 and the fine steel mesh 3 are expanded outward, and then according to the set thickness of the insulation layer, the graphene insulation board 1 is vertically inserted into the middle steel bar, and then the graphene insulation board 1 is vertically inserted into the middle steel bar, and then the graphene insulation board 1 is vertically inserted into the middle steel bar, and then the graphene insulation board 1 is vertically inserted into the middle steel bar, and then the graphene insulation board 1 is vertically inserted into the middle steel bar, and then the graphene insulation board 1 is vertically inserted into the middle steel bar, and then the graphene insulation board 1 is vertically inserted into the middle steel bar, and then the graphene insulation board 1 is vertical According to the thickness requirement of the structural concrete, the length of the connecting mechanism 7 is adjusted, and then the exterior decorative panel 6 is installed and fixed. After the adjustment and installation of the wall outer frame is completed, the structural concrete is first injected between the reinforcing steel mesh 5 and the exterior decorative panel 6. Due to the presence of the fine steel mesh 3, the structural concrete can be blocked to a certain extent, and the structural concrete will not penetrate into the outside of the fine steel mesh 3 in large quantities. After the structural concrete solidifies, the foamed concrete is injected between the graphene insulation board 1 and the fine steel mesh 3. After the foamed concrete solidifies, it cooperates with the graphene insulation board 1 to form an insulation layer.

[0040] In this embodiment, the fine steel mesh 3 and the reinforcing steel mesh 5 are both welded to the inner side of the outer frame plate 2 , and welding spots are evenly arranged at the bonding surfaces of the fine steel mesh 3 and the reinforcing steel mesh 5 .

[0041] Partial working principle: The welding fixation method can ensure the stability of the positions of the fine steel mesh 3 and the reinforced steel mesh 5, and avoid deformation of the steel mesh caused by high pressure from the concrete.

[0042] In this embodiment, the extension mechanism 4 includes a strip groove 401, a horizontal plate 402, a vertical rod 403, a through groove 404, a support plate 405, a connecting rod 406, a hinge seat 407 and a positioning assembly. The strip groove 401 is opened at the inner bottom of the graphene insulation board 1 along the length direction of the graphene insulation board 1, and both ends of the strip groove 401 pass through the graphene insulation board 1. The inside of the strip groove 401 is horizontally provided with a horizontal plate 402, and the horizontal plate 402 slides vertically inside the strip groove 401. The top of the graphene insulation board 1 is evenly provided with through grooves 404 in a rectangular array. The through grooves 404 are arranged on the top of the graphene insulation board 1. 04 are horizontally opened in three rows, and vertical rods 403 are vertically slidably arranged on the horizontal plate 402. The number of vertical rods 403 and the through slots 404 is the same. The vertical rods 403 penetrate the through slots 404 in the same vertical column, and support plates 405 are vertically slidably arranged inside the through slots 404. The support plates 405 are fixedly connected to the vertical rods 403. Connecting rods 406 are hingedly installed on both sides of the support plates 405. Articulated seats 407 are installed at the ends of the connecting rods 406. The articulated seats 407 are fixed on the fine steel mesh 3. A positioning component for fixing the initial position of the horizontal plate 402 is provided on the horizontal plate 402.

[0043] Local working principle: when in use, according to the thickness requirement of the insulation layer, the horizontal plate 402 is controlled to slide inside the strip groove 401. The initial position of the horizontal plate 402 is located at the bottom end of the strip groove 401. As the initial position of the horizontal plate 402 is adjusted upward, the side push distance of the fine steel mesh 3 will be shortened, and the graphene insulation board 1 is inserted and fixed at the bottom. The steel bar is inserted into the interior of the graphene insulation board 1, which will exert an upward thrust on the horizontal plate 402. At this time, the horizontal plate 402 will drive the vertical rod 403 to move upward, and the upward movement of the vertical rod 403 will drive multiple groups of support plates 405 on the same vertical column to move upward. The upward movement of the support plate 405 controls the connecting rod 406 to expand outward, and the outer frame plate 2 contacts the top of the foundation, thereby pushing the fine steel mesh 3 on the outer frame plate 2 to move outward, thereby changing the distance between the graphene insulation board 1 and the fine steel mesh 3.

[0044] In this embodiment, support rods 408 are horizontally slidably installed on both sides of the top of the through groove 404, and the ends of the support rods 408 away from the graphene insulation board 1 are connected to the hinge seat 407.

[0045] Local working principle: The use of the support rod 408 ensures that the outer frame plate 2 can only move horizontally, and limits the state of the outer frame plate 2. The bottom end of the outer frame plate 2 and the bottom of the graphene insulation board 1 are always in a horizontal state.

[0046] In this embodiment, the positioning assembly includes a screw 409, a sliding hole 4010, a mounting rod 4011 and an extrusion block 4012. The screw 409 is threadedly installed at one end of the horizontal plate 402. The sliding holes 4010 that cooperate with the vertical rods 403 are evenly opened on the horizontal plate 402. The vertical rods 403 all vertically pass through the inside of the sliding holes 4010. The interior of the horizontal plate 402 is slidably provided with mounting rods 4011 along the length direction. Extrusion blocks 4012 are fixed on the mounting rods 4011. The extrusion blocks 4012 are all located on the sides of the sliding holes 4010. The end of the screw 409 is rotatably connected to the extrusion block 4012 at the end of the mounting rod 4011.

[0047] Local working principle: During the upward adjustment of the horizontal plate 402, the horizontal plate 402 moves upward along the vertical rod 403. After moving to the specified position, the screw 409 is rotated, and the screw 409 moves toward the inside of the horizontal plate 402. The screw 409 applies a thrust to the mounting rod 4011 and the extrusion block 4012. The extrusion block 4012 will be tightly attached to the surface of the vertical rod 403, thereby fixing the position of the horizontal plate 402.

[0048] In this embodiment, mounting holes 4072 are provided at positions of the fine steel mesh 3 corresponding to the hinge seats 407, threaded holes 4071 are provided on the mating surfaces of the hinge seats 407 and the fine steel mesh 3, and bolts 4073 are evenly provided on the side of the fine steel mesh 3 away from the hinge seats 407. The bolts 4073 pass through the mounting holes 4072 and are threadedly installed into the interior of the threaded holes 4071.

[0049] Partial working principle: When connecting the fine steel mesh 3 and the hinge seat 407, first align the threaded hole 4071 on the hinge seat 407 with the mounting hole 4072, then pass the bolt 4073 through the mounting hole 4072, and then thread it into the inside of the threaded hole 4071 to complete the fixation of the fine steel mesh 3.

[0050] In this embodiment, the connecting mechanism 7 includes a socket 701, a sliding rod 702, a fixing block 703, a hanging hole 704 and a limiting assembly. The socket 701 is evenly fixed on the outside of the reinforcing steel mesh 5. The ends of the socket 701 are slidably installed with sliding rods 702. The ends of the sliding rods 702 away from the socket 701 are fixed with fixing blocks 703. The exterior panels 6 are provided with hanging holes 704 that cooperate with the fixing blocks 703. The interior of the socket 701 is provided with limiting assemblies for limiting the sliding rods 702.

[0051] Local working principle: During the assembly process, first control the length of the connecting mechanism 7 according to the requirement of the thickness of the structural concrete, slide the sliding rod 702 inside the sleeve 701, and the distance between the fixed block 703 at the end of the sliding rod 702 and the far end of the sleeve 701 is the thickness of the structural concrete. After the length adjustment of the connecting mechanism 7 is completed, align the hanging hole 704 with the fixed block 703, and then push the exterior panel 6 toward the direction of the graphene insulation board 1. When the fixed block 703 enters the interior of the hanging hole 704, the exterior panel 6 is released, the exterior panel 6 moves down, and the fixed block 703 is inserted into the interior of the exterior panel 6 to limit the exterior panel 6.

[0052] In this embodiment, the bottom end of the hanging hole 704 is circular, and the inner diameter of the bottom end of the hanging hole 704 is larger than the outer diameter of the fixing block 703 , the top end of the hanging hole 704 is rectangular, and the width of the top end of the hanging hole 704 is the same as the diameter of the sliding rod 702 .

[0053] Partial working principle: when the outer decorative panel 6 moves downward, the sliding rod 702 is stuck at the top of the hanging hole 704, and the fixing block 703 is limited inside the outer decorative panel 6 to ensure that the position of the outer decorative panel 6 is stable.

[0054] In this embodiment, the limiting assembly includes an annular groove 705, a connecting groove 706 and a protrusion 707. The annular groove 705 is evenly arranged on the outer side of the sliding rod 702 along the circumferential direction. A connecting groove 706 is arranged between adjacent annular grooves 705. A protrusion 707 is fixed to the inner end of the sleeve 701, and the protrusion 707 slides inside the annular groove 705 and the connecting groove 706.

[0055] Partial working principle: When adjusting the position of the slide rod 702, rotate the slide rod 702, align the position of the protrusion 707 with the connecting groove 706, and then pull the slide rod 702 horizontally. When the extended length is reached, rotate the slide rod 702 again, and insert the protrusion 707 into another annular groove 705 to fix the position of the slide rod 702.

[0056] In this embodiment, a filling hole 708 is formed at one end of the plug sleeve 701 close to the fixing block 703 , and the filling hole 708 penetrates to the inner side of the plug sleeve 701 .

[0057] Partial working principle: After the structural concrete is poured between the reinforcing steel mesh 5 and the exterior panel 6, the structural concrete will enter the interior of the sleeve 701 through the filling hole 708, and fix the position of the sliding rod 702 again, ensuring the stability of the wall.
