[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0025] This application provides a connection structure between a waterproof ALC wall panel and a main body, mainly used to solve the problem that there is a joint seam at the splicing of ALC wall panels, the interfaces between ALC wall panels and upper and lower beams and columns, making it difficult to handle the water seepage of the exterior wall, which affects the aesthetics and use of the building, and provides the following technical solutions, which will be described in detail below in combination with Figures 1-5 for a detailed description:

[0026] A connection structure between a waterproof ALC wall panel and the main body mainly includes several wall panel bodies 1, two frame columns 2 and two frame beams 3. The several wall panel bodies 1 are horizontally arrayed. A number of reserved perforations 11 arranged in an array are penetrated through the wall panel body 1. The reserved perforations 11 are horizontally arranged, and an integral tie bar 12 is inserted into the interiors of the reserved perforations 11 located on the same horizontal line. The diameter of the tie bar 12 is 10 mm, and the adjacent two tie bars 12 are spaced 500 mm apart. A post-cast strip is formed between two adjacent wall panel bodies 1, and post-cast strip concrete body 4 is poured. The thickness of the post-cast strip concrete body 4 is 100 mm. The several wall panel bodies 1 and the several post-cast strip concrete bodies 4 constitute a precast wall panel. The two frame columns 2 are respectively located on the vertical sides opposite to the two outermost wall panel bodies 1. The two ends of the tie bar 12 are respectively inserted into the interiors of the two frame columns 2. The two frame beams 3 are respectively installed on the top side and the bottom side of the several wall panel bodies 1. The specific installation process of this connection structure is as follows: First, horizontally array and fix the several wall panel bodies 1 at the predetermined positions according to the design requirements. Insert the integral tie bar 12 into the reserved perforations 11. The diameter of the tie bar 12 is set to 10 mm, and ensure that the center distance between two adjacent tie bars 12 is 500 mm. A post-cast strip is formed between two adjacent wall panel bodies 1, and then pour the post-cast strip concrete body 4 with a thickness of 100 mm to fill the gap between the wall panel bodies 1 and enhance the stability of the overall structure. Then, place the two frame columns 2 respectively on the vertical sides opposite to the two outermost wall panel bodies 1 to ensure that the two ends of the tie bar 12 can be inserted into the interiors of the frame columns 2. Finally, install the two frame beams 3 respectively on the top side and the bottom side of the wall panel body 1 to ensure the firm connection between the frame beam 3 and the wall panel body 1. Through the above steps, the several wall panel bodies 1 and the several post-cast strip concrete bodies 4 jointly constitute a precast wall panel. In this solution, through the use of the tie bar 12 and the post-cast strip concrete body 4, the connection between the wall panel bodies 1 is enhanced, and the stability of the overall structure is improved. The use of the post-cast strip concrete body 4 effectively reduces the gap between the wall panels, significantly improves the waterproof performance of the wall. The design of the precast wall panel simplifies the construction process, speeds up the construction speed, and improves the construction efficiency. Due to the improvement of the structural stability and waterproof performance, the maintenance cost caused by problems such as water seepage in the later stage is reduced.

[0027] In this embodiment, please refer to Figure 3 and Figure 4, notches 13 are constructed on both the top side and the bottom side of the precast wall panel. Lugs 31 are fixed on both of the two frame beams 3. The two lugs 31 correspond to the two notches 13 respectively. The lug 31 is movably inserted into the corresponding notch 13, and a rabbet 14 is formed between the outer wall of the lug 31 and the inner wall of the corresponding notch 13. The interior of the rabbet 14 is filled with cement mortar; the grade of the cement mortar is C30. During specific operation, first, accurately measure and mark the position of the notch 13 at the predetermined position of the wall panel body 1, and use appropriate tools and techniques to process the notch 13 on the wall panel to ensure accurate dimensions and regular shapes. Then, fix the lug 31 at the accurate position on the frame beam 3 to ensure its correct position and alignment with the wall panel notch 13. Then, insert the lug 31 into the corresponding notch 13, adjust the position of the lug 31 to ensure the formation of the rabbet 14. Finally, fill the prepared C30 cement mortar into the interior of the rabbet 14 to ensure dense filling without voids. Through the design of the notch 13 and the lug 31, the connection stability between the frame beam 3 and the wall panel body 1 is enhanced. The C30 cement mortar filled in the interior of the rabbet 14 provides an additional waterproof layer, effectively preventing water penetration.

[0028] Further, please refer to Figure 5 , two vertical connecting bars 41 are arranged inside the post-cast strip concrete body 4. The two connecting bars 41 are connected by a plurality of stirrups 42; the diameter of the connecting bar 41 is 12 mm, the diameter of the stirrup 42 is 8 mm, and the distance between adjacent two stirrups 42 is 200 mm. During specific operation, first, accurately measure the position of the post-cast strip and mark it. Cut the connecting bar 41 and the stirrup 42 according to the required length, and use appropriate binding techniques to bind and connect the stirrup 42 with the connecting bar 41 to ensure the stability of the structure. Then, install the formwork at the position of the post-cast strip to form the required shape of the post-cast strip concrete body 4. Then, pour the concrete into the formwork while ensuring that the steel bars do not displace. Finally, after the concrete reaches a certain strength, remove the formwork and carry out curing. By arranging the connecting bar 41 and the stirrup 42 inside the post-cast strip concrete body 4, the integrity and structural stability of the post-cast strip concrete body 4 are enhanced. The reasonable arrangement of the stirrup 42 helps to reduce the cracking risk of the concrete body, reducing the cost of later maintenance and repair.
