Technical Field

[0001] The utility model relates to the technical field of thermal insulation wall panels, in particular to a thermal insulation wall panel for assembled building exterior walls. Background Art

[0002] External wall insulation is made of polymer mortar, glass fiber mesh, flame retardant molded polystyrene foam board (EPS) or extruded board (XPS) and other materials, and is bonded on site. The new thermal insulation decorative integrated board is produced through an assembly line, integrating thermal insulation, waterproofing, and finishing functions. It is the preferred material to meet the current energy-saving needs of housing construction and improve the thermal insulation level of industrial and civil buildings. It is also the preferred material for energy-saving renovation of existing buildings.

[0003] A Chinese utility model patent with publication number CN211714247U discloses an assembled building wall panel structure, including inner wall panels and outer wall panels, wherein an insulation layer is arranged between the inner wall panels and the outer wall panels, and a connecting strip section is arranged at one end of the insulation layer outside one end of the inner wall panels and the outer wall panels, and a connecting gap with a width equal to the connecting strip section and less than the width of the insulation layer is left at one end of the inner wall panels and the outer wall panels away from the connecting strip section, and the connecting strip section of the insulation layer is arranged in the connecting gap in the adjacent wall panel structure.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: when workers install prefabricated buildings, they need to connect adjacent insulation wall panels, and in the above-mentioned device, workers need to connect the connecting strip segments with the connecting gaps. In the actual installation process, due to the problem of material tolerance, the width of the connecting strip segment is easily slightly larger than the width of the connecting gap, which easily causes the connecting strip segment to get stuck in the connecting gap, which is not conducive to reducing the difficulty of operation for workers. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a heat-insulating wallboard for an assembled building exterior wall.

[0006] The above technical purpose of the utility model is achieved through the following technical scheme: an insulation wall panel for assembled building exterior walls, including a wall panel body, a mounting rod is fixed on the side wall on one side of the wall panel body, a mounting groove with a width greater than the width of the mounting rod is provided on the side wall on the other side of the wall panel body, a sliding groove is provided on the two side walls opposite to the mounting rod, a fixed plate is slidably arranged in the sliding groove, and a driving component for driving the fixed plate is provided on the mounting rod.

[0007] By adopting the above technical solution, when the staff needs to connect the wall panel bodies, the staff needs to keep one of the wall panel bodies stable and connect the mounting rod on the other wall panel body to the mounting groove. Since the width of the mounting rod is smaller than the width of the mounting groove, the probability of the mounting rod getting stuck during the installation process is reduced. Furthermore, the staff only needs to start the driving assembly to move the two fixing plates away from each other at the same time, so that the two fixing plates are respectively pressed against the two inner walls of the mounting groove, so that the two wall bodies remain stable.

[0008] Furthermore, a threaded groove is provided on the upper surface of the mounting rod, a fixing groove is provided on the inner bottom wall of the threaded groove, and connecting grooves that are interconnected with the fixing grooves are provided on the inner walls of the two sliding grooves.

[0010] By adopting the above technical solution, when the staff connects the installation rod and the installation groove to each other, the staff only needs to rotate the threaded rod to move the threaded rod and the fixed rod downward, and then make the fixed rod press against the inclined surface, so that the connecting rod moves away from the threaded rod under the action of the fixed rod, so that the fixed plate follows the movement of the connecting rod and presses against the inner wall of the installation groove, thereby reducing the operation difficulty of the staff.

[0011] Furthermore, a hexagonal groove is provided on the upper surface of the threaded rod to reduce the difficulty for workers to rotate the threaded rod.

After being melted at a high temperature of more than 1450℃, it is centrifuged into fibers by an internationally advanced four-axis centrifuge at high speed. At the same time, a certain amount of adhesive, dust-proof oil, and water-repellent agent are sprayed in, and then collected by a cotton collector, and solidified and cut after being spread by the pendulum method and three-dimensional cotton. It has good fireproof performance. KMPS fireproof insulation board is a hard non-combustible insulation material. It uses special lightweight fireproof materials as gelling materials, flame-retardant foaming particles as aggregates, and dozens of modifiers are added. It is a high-quality fireproof insulation material produced by an automated production line. The modified benzene board has good waterproof and thermal insulation properties, which is conducive to improving the thermal insulation performance of the insulation layer.

[0016] Furthermore, a ceramic facing layer is provided on the side wall of the exterior wall panel away from the interior wall panel.

[0017] Furthermore, the thickness of the ceramic finishing layer is 4-5.5 mm.

[0018] By adopting the above technical solution, the ceramic has good hardness and corrosion resistance, and the ceramic finishing layer made of ceramic has good oxidation resistance, thereby reducing the probability of damage to the surface pattern of the ceramic finishing layer, which is beneficial to improving the user experience of the staff.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. In this application, when the staff needs to connect the wall panel bodies, the staff needs to keep one of the wall panel bodies stable and connect the mounting rod on the other wall panel body to the mounting groove.
