[0006] The control unit includes an aluminum strip and a self-tapping screw. The aluminum strip is arranged on the top side of the composite plate and extends outward a predetermined distance. Through holes are arranged at intervals on the aluminum strip. The self-tapping screw passes through the through holes and is fixed to the composite plate. The aluminum strips between two adjacent composite plates are connected to each other.

[0007] In one example, in two adjacent aluminum strips connected to each other in the composite plates, a groove is provided at the end of one aluminum strip, and a protrusion is provided at the end of the other aluminum strip, and the protrusion is inserted into the groove.

[0008] In one example, a baffle is provided at the middle of the bottom surface of the aluminum strip along the length direction, and the baffle is used to abut against the side of the composite plate to limit the movement of the aluminum strip relative to the composite plate.

[0009] In one example, the aluminum strip is provided with strip openings at intervals along the length direction, the length direction of the strip openings is consistent with the width direction of the aluminum strip, and the strip openings extend inwardly by a predetermined distance from the position of the baffle.

[0020] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0021] See also Figures 1 to 4 , this embodiment provides a composite plate joint control device, including a plate unit and a control unit.

[0022] The plate unit includes a plurality of composite plates 11 installed on a support system. The control unit includes an aluminum strip 21 and a self-tapping screw 22. The aluminum strip 21 is installed on the top side of the composite plate 11 and extends outward by a predetermined distance. Through holes are provided at intervals along the length direction on the aluminum strip 21. The self-tapping screw 22 passes through the through hole and is screwed into the composite plate 11, thereby fixing the aluminum strip 21 to the composite plate 11. The aluminum strip 21 between two adjacent composite plates 11 is connected to each other, thereby limiting the movement of the composite plate 11 on the one hand and making the connection between the composite plates 11 tighter on the other hand. In the utility model, the thickness of a single piece of the aluminum strip 21 is 2 mm, which will not affect the safety of the structure. After the concrete is poured, the surface can be directly plastered later. The self-tapping screw 22 is screwed into the composite plate 11 by 18 mm, and the decorative layer can be directly constructed at the bottom, and the exposed part of the surface layer is poured together with the concrete.

[0023] In order to improve the docking effect, in the two aluminum strips 21 connected to the two adjacent composite plates 11, a groove 24 is provided at the end of one aluminum strip 21, and a protrusion 23 is provided at the end of the other aluminum strip 21. The protrusion 23 is inserted into the groove 24, so that the two aluminum plates are connected more tightly, which can further avoid the occurrence of leakage problems.

[0024] In order to improve the fixing effect, a stop bar 25 is provided in the middle of the bottom surface of the aluminum strip 21 along the length direction. The stop bar 25 is close to the side of the laminated plate 11 to limit the movement of the aluminum strip 21 relative to the laminated plate 11.

[0025] In order to facilitate the adjustment of the fixed position of the aluminum plate strips 21, strip openings 26 are provided at intervals along the length direction of the aluminum plate strips 21. The length direction of the strip openings 26 is consistent with the width direction of the aluminum plate strips 21, and the strip openings 26 extend inward by a predetermined distance from the position of the baffle 25. When the baffle 25 is abutted against the side of the composite plate 11, the position of one of the aluminum plate strips 21 can be adjusted, and a pad can be placed into the side of the composite plate 11 through the strip openings 26, so that after the position of the aluminum plate strips 21 is adjusted, the pad can still be inserted through the strip openings 26 to ensure the effective limiting of the aluminum plate strips 21.

[0026] Construction method: First, place the composite board 11 into the support system according to the design requirements, and make the joints neat; then lay the aluminum strips 21 flat along the length direction of the composite board 11, and make the two adjacent aluminum strips 21 face each other, and insert the corresponding protrusions 23 into the grooves 24; finally, fix the aluminum strips 21 on the composite board 11 by self-tapping screws 22, and smooth the joints between the composite boards 11 below after demolding. Compared with the prior art, the composite board joint control device of the utility model is a key component for connecting the joints between the composite boards 11 without demolding, which can make the connection between the composite boards 11 tighter, form a closed whole, avoid the displacement of a single template, and eventually cause the template joints to be too large, and cause quality risks such as leakage. The aluminum strips 21 in the utility model are easy to install, and the required tools are relatively common, and the operability is strong, which greatly reduces the difficulty of construction, can significantly increase the template installation efficiency, and save labor and construction period costs. The use of aluminum strips 21 to connect adjacent composite panels 11 can play a fixing and sealing role, reducing deformation and displacement caused by concrete pouring; the aluminum strips 21 play a vital role in the construction of ultra-thin prefabricated thermal insulation composite panels 11, and at the same time have the advantages of low cost, convenient construction, and green environmental protection, and are suitable for promotion in the construction of ultra-thin prefabricated thermal insulation composite panels 11 in construction projects.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
