Technical Field

[0001] This utility model belongs to the field of building wall panel design technology, and specifically relates to a prefabricated building insulation wall panel. Background Technology

[0002] Building insulation wall panels mainly include rock wool boards, polyurethane boards, and polystyrene foam boards. Among them, polyurethane insulation boards are boards with polyurethane insulation materials. They are mainly used as thermal insulation materials and are widely used in color steel sandwich panels, central air conditioning, building wall materials, cold storage, cold rooms, insulated boxes, chemical tanks and other fields.

[0003] Currently, Chinese patent with publication number CN222575794U and publication date of March 7, 2025 discloses a rapid assembly structure for polyurethane insulation boards, including a board body one, a snap-fit ​​plate one fixedly connected to the left part of the bottom end of the board body one, a snap-fit ​​groove one opened on both the left and right parts of the top end of the board body one, a limiting mechanism snapped into the right part of the top end of the board body one, a fixing mechanism inserted into the right part of both the front and rear ends of the board body one, and a board body two overlapping the right part of the board body one.

[0004] The rapid assembly structure of this type of polyurethane insulation board, which uses a limiting mechanism for assembly, is complex and difficult to process, thus preventing its widespread adoption in actual production. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated building insulation wall panel that facilitates convenient and stable assembly.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a prefabricated building insulation wall panel, comprising two wall panel bodies, each wall panel body comprising a hollow frame, a partition frame disposed within the frame, and a first polyurethane layer filled within the partition frame. A splicing assembly is provided between two adjacent wall panel bodies. The splicing assembly comprises two buckles with a cross-section in the shape of a "U", splicing plates disposed on both sides of the buckles, a through hole opened in the middle of the buckles, and a connecting bolt that passes through the through holes of the two buckles and is connected by a nut thread. An insert plate is provided on the side of the frame and embedded in the inner side of the splicing plate. Multiple fastening teeth are provided on the outer wall of the insert plate, and tooth grooves for the multiple fastening teeth to be embedded are provided on the inner wall of the splicing plate.

[0007] A further feature of this invention is that the cross-section of the plug-in plate is L-shaped, and a rubber sealing strip is provided on the side wall of the plug-in plate.

[0008] A further feature of this invention is that both sides of the buckle are provided with inclined surfaces for abutting against the rubber sealing strip.

[0009] A further feature of this invention is that a second polyurethane layer is provided on the side of the frame and in the position between the two plug-in plates.

[0010] A further feature of this invention is that a third polyurethane layer is provided between the two buckles for the connecting bolt to pass through.

[0011] A further feature of this invention is that the side of the third polyurethane layer is arc-shaped and is used to press against the second polyurethane layer after being subjected to extrusion pressure.

[0012] A further feature of this invention is that the first polyurethane layer includes a central polyurethane portion located at the center of the frame and side polyurethane portions located on the sides of the frame and distributed alternately with the central polyurethane portion.

[0013] In summary, this utility model has the following beneficial effects:

[0014] 1. When assembling two wall panels, insert the plug plate on the side of the frame into the inside of the splicing plate, and insert the snap-fit ​​teeth into the tooth groove. Then, use the connecting bolt to pass through the through holes of the two clips and connect them with the nut thread. At this time, the two clips can assemble and snap the sides of the two wall panels, which will facilitate the convenient and stable assembly of the two wall panels.

[0015] 2. The L-shaped cross-section of the plug-in plate, along with the rubber sealing strip on its side wall, seals the gap between the clip and the plug-in plate, thereby improving the sealing performance of the two wall bodies after assembly.

[0016] 3. By utilizing the inclined surfaces on both sides of the buckle, when the two buckles are locked together towards each other by the connecting bolts, the inclined surfaces will shift towards the rubber sealing strip and press against it, which will ultimately help to further improve the sealing performance of the two wall bodies after assembly.

[0017] 4. By utilizing the second polyurethane layer installed on the side of the frame and located between the two plug-in plates, the second polyurethane layer can fill the space between the two plug-in plates, thereby improving the thermal insulation performance at the splicing position of the two wall bodies.

[0018] 5. By using the third polyurethane layer between the two clips for the connecting bolts to pass through, the third polyurethane layer can fill the space between the two clips, thereby further improving the thermal insulation performance at the joint of the two wall bodies.

[0019] 6. When the two clips are locked together towards each other by the connecting bolts, the clips can exert pressure on the third polyurethane layer. Then the arc-shaped side of the third polyurethane layer can be squeezed outward and pressed against the second polyurethane layer, which is conducive to the stable contact between the third polyurethane layer and the second polyurethane layer.

[0020] 7. The first polyurethane layer includes a central polyurethane portion and side polyurethane portions. Since the central polyurethane portion and the side polyurethane portions are staggered, sufficient heat insulation effect can be ensured while reducing the amount of polyurethane material used, which ultimately helps to reduce the production cost of the wall panel body.
