The outer periphery of the sleeve 201 is provided with a plurality of groups of support assemblies extending along the axial direction thereof, each group of support assemblies includes a plurality of support rods 204 hinged to the side wall of the sleeve 201 and parallel to each other, and the outer ends of the support rods 204 of each group of support assemblies are hinged with a connecting piece 205, and one end of the connecting piece 205 close to the prefabricated plate 100 is vertically connected to a limiting piece 206, and the limiting piece 206 is matched and embedded in the corresponding rectangular opening 102, and slides in the radial direction of the sleeve 201 in the rectangular opening 102, and a worm wheel 207 meshing and rotating with the worm 104 is coaxially fixedly sleeved on the rotating shaft 200; Among them, the diameter of each first hole is larger than the diameter of the corresponding sleeve 201, and the diameter of each first hole is smaller than the distance between the farthest ends of the two opposite rectangular openings 102, and the multiple groups of plug-in components 210 on one side of any prefabricated panel are correspondingly plugged into the multiple first holes of the adjacent prefabricated panels.

[0018] The assembled prefabricated composite panel described in the above technical solution includes a plurality of prefabricated panels 100 and a plurality of matching adjustment components. A plurality of first holes are drilled on one side edge of each prefabricated panel 100, and these holes provide necessary connection points for subsequent assembly. On the other side edge of the prefabricated panel 100, a plurality of second holes 101 are correspondingly opened, and a plurality of radially extending rectangular openings 102 are cut around these holes. A cavity 103 connected to the plurality of second holes 101 and the rectangular openings 102 is constructed inside the prefabricated panel 100. In this cavity 103, a worm 104 is installed, one end of which is connected to an inner side wall of the cavity 103 by a rotating connector to ensure that it can rotate smoothly; and the other end rotates out of the prefabricated panel 100 through a bearing, and is firmly connected to an operating rod 105 for easy operation. The axis direction of the worm 104 is perpendicular to the axis direction of the plurality of second holes 101, so that the worm 104 can effectively drive the worm wheel 207 meshing therewith when rotating. Each set of adjusting components comprises a rotating shaft 200, one end of which is connected to the inner side wall of the cavity 103 opposite to the second hole through a rotating connector, and the other end is rotated through the corresponding second hole 101 through a bearing to pass through the prefabricated board 100 and connect the plug-in component 210. The diameter of the second hole 101 matches the diameter of the rotating shaft 200 and is coaxially arranged. The plug-in component 210 is provided with a sleeve 201 coaxially sleeved with the end of the rotating shaft 200, the inner wall of the sleeve 201 is provided with an internal thread 203 matching the external thread 202, and the outer periphery of the sleeve 201 is provided with a plurality of support components extending along its axial direction, and each support component is composed of a plurality of support rods 204 that are rotatably connected to the side wall of the sleeve 201 and are parallel to each other.

This stopper 206 can accurately match the card embedded in the corresponding rectangular opening 102, and slide along the radial direction of the sleeve 201 in the rectangular opening 102. A worm wheel 207 that perfectly meshes and rotates with the worm 104 is also coaxially fixedly sleeved on the rotating shaft 200. When the operating rod 105 is rotated, the worm 104 will rotate accordingly, thereby driving the meshed worm wheel 207 to rotate, and the rotation of the worm wheel 207 will drive the rotating shaft 200 to rotate. The diameter of the first hole needs to meet the insertion of the plug-in component 210, and at the same time, it needs to leave space for the support rod 204 to rotate, and by adjusting the distance between the multiple support rods 204, the two adjacent prefabricated panels 100 can be kept flush. During the assembly process, the multiple groups of plug-in components 210 on one side of any prefabricated panel 100 can be correspondingly plugged into the multiple first holes coaxial with the second holes of the adjacent prefabricated panel 100 .By rotating the operating rod 105, the worm 104 and the multiple worm wheels 207 meshing therewith can be driven to rotate, thereby driving the multiple rotating shafts 200 to rotate, and at the same time, the sleeve 201 moves along the axis direction of the rotating shaft 200 toward the second hole 101, thereby driving the support assembly and the stopper 206 to slide radially, and the angle between the multiple supporting rods 204 and the sleeve 201 gradually increases until the multiple connecting members 205 are tightly fitted with the inner wall of the first hole, so that the rotating shaft 200 and the sleeve 201 are coaxially connected with the corresponding first hole, thereby completing the alignment of two adjacent prefabricated panels 100. The assembled prefabricated composite panel is not only compact in structure and strong in bearing capacity, but also easy to align and install, which greatly improves the construction efficiency and flexibility of the building structure.

[0019] In another technical solution, the rotating shafts 200 of the multiple adjustment components are parallel to each other and perpendicular to the worm 104. In this technical solution, the axis direction of the rotating shaft 200 is perpendicular to the axis direction of the worm 104, and the rotation of the worm 104 can drive the rotating shaft 200 to rotate, thereby improving the structural stability.

[0020] In another technical solution, the multiple connectors 205 are parallel to the shaft 200. In this technical solution, the length direction of the multiple connectors 205 is parallel to the axial direction of the shaft 200, ensuring that the multiple connectors 205 are symmetrically arranged on the periphery of the shaft 200, thereby improving structural stability.

[0021] In another technical solution, the two opposite side walls of each stopper 206 are provided with symmetrical ridges 208, the outer side wall of each ridge 208 is provided with a plurality of freely rotatable balls 209, the two opposite side walls of each rectangular opening 102 are provided with symmetrical slide grooves, each stopper 206 is matched and accommodated in the corresponding rectangular opening 102, so that the two ridges 208 are matched and inserted into the two corresponding slide grooves, and the stopper 206 slides along the slide groove. In this technical solution, ridges 208 are provided on both sides of the stopper 206, and slide grooves corresponding to the ridges 208 are provided in the rectangular opening 102, so that the stopper 206 can slide in the rectangular opening 102 along the slide groove, and a plurality of balls 209 are provided to ensure smooth sliding.

[0022] In another technical solution, the length directions of the plurality of ridges 208 and the plurality of slide grooves are perpendicular to the axis direction of the corresponding second hole 101, and the sliding directions of the plurality of stoppers 206 are perpendicular to the axis direction of the corresponding second hole 101. In this technical solution, the sliding of the plurality of stoppers 206 drives the distance between the plurality of connectors 205 to change, so that the distance between the plurality of connectors 205 matches the diameter of the first hole, thereby facilitating the adjustment of the flatness between adjacent prefabricated panels 100.

[0023] In another technical solution, a side wall of each prefabricated board 100 adjacent to the plurality of second holes 101 is provided with an operating groove 106 for accommodating the operating rod 105, and the depth of the operating groove 106 is greater than the thickness of the operating rod 105. In this technical solution, the operating rod 105 is arranged in the operating groove 106, which does not affect the installation of the composite board, and after the top surface of the composite board is adjusted to be flush, the operating groove 106 can be closed and decorated without affecting the use effect.

[0024] In another technical solution, a plurality of reinforcing ribs are evenly distributed in each prefabricated panel 100, and a steel mesh is commonly connected to the top of the reinforcing ribs, and the prefabricated panel 100 is filled with concrete. In this technical solution, reinforcing ribs and steel mesh are arranged in the prefabricated panel 100, and the prefabricated panel 100 is filled with concrete, which effectively improves the strength of the prefabricated panel 100.
