[0024] like Figure 1 and Figure 3 As shown, a building facade wall structure includes a building body, a floor slab 10 and an inner wall 11. The floor slab 10 is embedded and fixedly connected to the building body, and the floor slab 10 extends horizontally. The inner wall 11 is vertically arranged and embedded and fixedly connected to the floor slab 10. It also includes a movable groove 12, a connecting rod 13, a movable limit block 20, a threaded rod 21 and an outer wall panel 30. The movable groove 12 is opened on the floor slab 10 and opens toward the end of the floor slab 10 away from the building body. The movable limit block 20 is set in the movable groove 12 and slides toward the opening direction of the movable groove 12. The threaded rod 21 passes through the movable limit block 20 along the sliding direction of the movable limit block 20. One end of the threaded rod 21 extends through the inner wall of the movable groove 12 to the interior of the floor slab 10. The threaded rod 21 is rotatably connected to the floor slab 10 and is threadedly connected to the movable stopper 20. The end of the movable stopper 20 facing the opening of the movable groove 12 extends outside the movable groove 12. The exterior wall panel 30 is disposed on the side of the interior wall 11 away from the floor slab 10. The exterior wall panel 30 abuts the end of the movable stopper 20. One end of the connecting rod 13 passes through the exterior wall panel 30 and extends into the interior wall 11, where it is embedded and fixedly connected. A nut is provided at the end of the connecting rod 13 away from the interior wall 11, which limits the axial movement of the exterior wall panel 30 along the connecting rod 13. A gap is formed between the exterior wall panel 30 and the interior wall 11. An insulation board 32 is provided in the gap. The insulation board 32 is plugged into the connecting rod 13, and one end of the insulation board 32 abuts the end of the movable stopper 20 extending outside the movable groove 12.

[0025] like Figure 2-4As shown, a plurality of exterior wall panels 30 are provided. The plurality of exterior wall panels 30 are laid flat on a side of the inner wall 11 away from the floor 10. Space exists between vertically adjacent exterior wall panels 30, and horizontally adjacent exterior wall panels 30 are arranged in abutment with each other. Insertion slots 31 for passing through the exterior wall panels 30 are vertically provided on both sides of the exterior wall panels 30 facing the horizontal laying direction. The insertion slots 31 opened on vertically adjacent exterior wall panels 30 are aligned. Insertion rods 40 are provided in the insertion slots 31 in a mortise and tenon connection. The insertion rods 40 extend in the vertical direction and pass through the plurality of vertically laid exterior wall panels 30. A blocking plate 41 is provided between vertically adjacent exterior wall panels 30 to block the space between adjacent exterior wall panels 30. The blocking plate 41 has prefabricated holes 42 near both ends of the blocking rods 40. Bolt fasteners are provided in the prefabricated holes 42. The blocking plate 41 is fixedly connected to the blocking rods 40 by the bolt fasteners. A mounting groove 44 is vertically provided on one side of the plug rod 40 away from the inner wall 11, and mounting protrusions 43 are provided on the side of the sealing plate 41 with prefabricated holes 42 at both ends facing the inner wall 11. The mounting protrusions 43 are engaged with the mounting groove 44.

[0026] like Figure 2-3 As shown, the part of the movable limit block 20 extending to the outside of the movable groove 12 is vertically penetrated by a flow channel 22, and the part of the movable limit block 20 located in the movable groove 12 is provided with a guide groove 23, one end of the guide groove 23 is connected to the flow channel 22, and the other end of the guide groove 23 is connected to the movable groove 12, and a grouting hole 33 is vertically opened on the insulation board 32, and there is a gap between the insulation board 32 and the inner wall 11 and the outer wall panel 30.

[0027] By rotating the threaded rod 21, the movable limit block 20 slides in the movable groove 12 under the action of the threaded structure. At this time, the length of the movable limit block 20 extending from the movable groove 12 can be adjusted, and then the distance between the exterior wall panel 30 and the interior wall 11 can be adjusted, so that different thicknesses of insulation layers can be installed on the exterior wall of the building, which is conducive to improving the degree of freedom of installing the insulation layer in the building. Before installing the exterior wall panel 30, the insulation board 32 is installed on the connecting rod 13. After the insulation board 32 and the connecting rod 13 are plugged in, the exterior wall panel 30 is installed on the side of the insulation board 32 away from the interior wall 11. At this time, the insulation board 32 is located between the exterior wall panels 30 to insulate the building. When a fire occurs in the building, the flames will not come into contact with the insulation layer, thereby preventing the insulation layer from burning and expanding the fire, which is conducive to improving the fire resistance of the building.

[0028] When the installation of the exterior wall panels 30 is completed, concrete mortar is used to fill the gaps between the exterior wall panels 30 and the insulation panels 32, as well as the gaps between the insulation panels 32 and the inner wall 11. At this time, the mortar can be filled through the spaces between several vertically adjacent exterior wall panels 30. In this way, the mortar filling can be made more sufficient through layered filling, and the spaces between the vertically adjacent exterior wall panels 30 can be blocked by the sealing panels 41 to isolate the insulation panels 32 from the external environment, further reducing the probability of external flames contacting the insulation panels 32, and further improving the fire resistance of the building.

[0029] When installing the sealing plate 41, the lateral position of the sealing plate 41 can be quickly positioned by snapping together the assembly protrusion 43 and the assembly groove 44, and then the sealing plate 41 and the plug-in rod 40 are fixed by bolt fasteners to complete the installation of the sealing plate 41. This can avoid deviations in the installation of the sealing plate 41 and improve the installation efficiency of the sealing plate 41.

[0030] When the exterior wall panels 30 and the sealing panels 41 are fully installed, concrete mortar is filled inward from the highest point of the building body into the grouting holes 33 and into the gap between the inner wall 11 and the insulation panel 32. At this time, the concrete mortar can flow onto the movable limit block 20, and then flow into the movable groove 12 through the guide groove 23 to fill the movable groove 12, thereby sealing the movable limit block 20 and the threaded rod 21 together in the floor slab 10, thereby improving the structural strength of the side of the floor slab 10 close to the inner wall 11, and can completely isolate the insulation panel 32 from the external environment after installation, thereby ensuring the service life of the insulation panel 32 while further reducing the possibility of fire igniting the insulation panel 32.
