[0028] The core of the utility model is to provide a wall panel structure to improve the thermal insulation effect of the assembled exterior wall.

[0029] Another core of the utility model is to provide an exterior wall enclosure system having the above-mentioned wall panel structure.

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] like Figure 1 As shown, an embodiment of the utility model discloses a wall panel structure, including a control system 100 and a wall panel body 200. It should be noted that the prefabricated exterior wall is a new type of building material, which is a plate composed of various materials, which can be prefabricated in a factory and then installed on site. Prefabricated exterior walls are highly standardized and modular, which can greatly improve construction efficiency and quality, and are widely used in prefabricated buildings. It is well known that the thermal insulation performance of the exterior walls of buildings is crucial to reducing energy consumption. However, the traditional prefabricated exterior wall structure still has the problem of heat conduction, resulting in energy waste, which makes the thermal insulation effect poor. The wall panel structure disclosed in the embodiment of the utility model is achieved by arranging multiple chambers 201 in the wall panel body 200, and each chamber 201 is interconnected through a transmission duct 203 located in the wall panel body 200. The air in each chamber 201 is extracted through a control system 100 to form a vacuum area in each chamber 201, thereby improving the thermal resistance of the wall panel body 200, reducing the thermal conductivity of the wall panel body 200, achieving energy-saving effects, solving the heat conduction problem existing in traditional prefabricated exterior wall structures, and further improving the thermal insulation effect of the prefabricated exterior walls.

[0032] Among them, Figures 1 to 4 As shown, a plurality of chambers 201 are provided in the wall panel body 200, and the chambers 201 are interconnected through a transmission duct 203 located in the wall panel body 200. A connection port 2032 is provided on the transmission duct 203, and the connection port 2032 is connected to the control system 100 through a connecting branch pipe 102 located on the outside of the wall panel body 200. At the same time, the air in each chamber 201 is extracted through the control system 100 to form a vacuum zone in each chamber 201, thereby forming a vacuum environment with high thermal resistance inside the wall panel body 200, which reduces heat loss and reduces the weight of the wall panel body 200, so as to facilitate the installation of the prefabricated exterior wall, and improves the thermal insulation effect of the prefabricated exterior wall, thereby solving the heat conduction problem existing in the traditional prefabricated exterior wall structure.

[0033] Furthermore, if Figures 2 to 4 As shown, in a specific embodiment, as Figure 3 and Figure 4As shown, the wall panel body 200 has two oppositely arranged side surfaces. For ease of understanding, the two side surfaces of the wall panel body 200 are defined as a first side surface and a second side surface. The first side surface of the wall panel body 200 is located indoors, and an interior decorative panel 205 is laid on the first side surface of the wall panel body 200. The second side surface of the wall panel body 200 is located outdoors, and an exterior decorative panel 204 is laid on the second side surface of the wall panel body 200. Figure 1 and Figure 2 As shown, the connecting branch pipe 102 is located on the indoor side, and the connecting branch pipe 102 connects the connecting port 2032 of the transmission conduit 203 with the control system 100 on the indoor side. In addition, in order to improve the overall aesthetics, the connecting branch pipe 102 and the control system 100 can be arranged above the ceiling, so as to hide the exposed connecting branch pipe 102 and the control system 100, thereby ensuring the aesthetics of the assembled exterior wall. In addition, in order to ensure the fire resistance of the assembled exterior wall, in this embodiment, the outer decorative board 204 and the inner decorative board 205 are both made of Class A fireproof board, which is not only fire-resistant and flame-retardant, but also makes the assembled exterior wall have excellent stability and integrity after the outer decorative board 204 and the inner decorative board 205 are installed, and has good fire resistance, which can confine the fire and smoke and toxic gas in the fire area, prevent the fire from spreading, block the generation of toxic gas, and improve the safety of the assembled building.

[0034] Furthermore, if Figures 1 to 4As shown, in order to improve the strength of the assembled exterior wall, in a specific embodiment, a plurality of heat-insulating support areas 202 are provided in the wall panel body 200, and the heat-insulating support areas 202 and the vacuum areas are alternately arranged along the vertical direction of the wall panel body 200. Specifically, the wall panel body 200 includes a wall panel support frame, and a plurality of layers of grids are provided on the wall panel support frame along the vertical direction of the wall panel body 200, and the heat-insulating support areas 202 and the vacuum areas are alternately distributed in sequence on each layer of grids along the vertical direction of the wall panel support frame. In the grid layer of the vacuum zone, an extruded board is used to enclose a sealed chamber 201, and the grid layer of the heat-insulating support zone 202 is filled with extruded boards, and the extruded boards can be stacked and placed in the grid layer to improve the strength of the heat-insulating support zone 202, thereby improving the strength of the entire assembled exterior wall. Compared with setting the entire wall panel body 200 as a vacuum zone, the strength of the assembled exterior wall is higher, which can prevent damage to the wall during transportation and installation. At the same time, the use of extruded boards as filling materials to increase strength can not only reduce the weight of the wall panel body 200 (compared to filling with lightweight concrete), but also have the effect of heat insulation. In addition, the material of the wall panel body 200 can be high-strength glass, ceramics or metal alloys with higher strength. In this embodiment, the wall panel body 200 uses light steel components made of metal alloys to form a wall panel support frame, which improves the strength of the assembled exterior wall while reducing the dead weight of the assembled exterior wall. Of course, other materials can also be used, which will not be repeated here.

[0035] Furthermore, if Figure 2 As shown, the chamber 201 includes a top chamber and a middle chamber, and a heat insulation support area 202 is provided between the top chamber and the middle chamber, the top chamber and the middle chamber are connected through a transmission duct 203, a connection port 2032 is located in the top chamber, and an air extraction port 2031 is provided on the transmission duct 203, and the air extraction port 2031 is located in the middle chamber to extract the air in the middle chamber through the transmission duct 203. Specifically, there are multiple middle chambers, each of which is connected to the top chamber through the transmission duct 203, and the transmission duct 203 is provided with an air extraction port 2031 at the position of each middle chamber, and multiple air extraction ports 2031 are provided along the circumference of the transmission duct 203 to improve the efficiency of air extraction of the control system 100. At the same time, setting the connection port 2032 in the top chamber can facilitate hiding the connecting branch pipe 102 connected to the connection port 2032 in the ceiling, and since the air density is lighter and can flow upward, setting the connection port 2032 in the top chamber can speed up the air extraction speed and improve the air extraction efficiency of the control system 100.

[0036] Furthermore, if Figure 1As shown, in a specific embodiment, a branch pipe control valve 1021 and a connection port 1024 are provided on the connecting branch pipe 102, and the connection port 1024 can be sealed and connected to the connection port 2032 of the transmission conduit 203, and the air extraction state of the connecting branch pipe 102 is controlled by the branch pipe control valve 1021. Specifically, the speed of air extraction of the connecting branch pipe 102 can be controlled by the branch pipe control valve 1021. Of course, if the vacuum degree of the vacuum zone meets the preset value, the extraction of the connecting branch pipe 102 can also be closed by the branch pipe control valve 1021. In addition, a detection port 1023 is provided between the branch pipe control valve 1021 and the connection port 1024, and the vacuum degree of the vacuum zone in the wallboard body 200 can be detected by a detection instrument at the detection port 1023. Of course, a vacuum sensor 1014 can also be set at the position of the detection port 1023 to automatically detect the vacuum degree of the vacuum zone in the wall panel body 200. When the vacuum degree of the vacuum zone in the wall panel body 200 does not meet the preset value, an alarm is issued to remind the user that the vacuum degree is insufficient. At this time, air can be extracted through the control system 100, and the branch pipe control valve 1021 is opened at the same time until the vacuum degree of the vacuum zone in the wall panel body 200 meets the preset value. In order to prevent the gas from flowing back when the branch pipe control valve 1021 is closed, a branch pipe check valve 1022 is set between the detection port 1023 and the branch pipe control valve 1021 to limit the flow direction of the gas along the connecting branch pipe 102 to flow from the wall panel body 200 to the control system 100, thereby ensuring that when the branch pipe control valve 1021 is closed, the gas will not enter the vacuum zone of the wall panel body 200.

[0037] Furthermore, if Figure 1As shown, in a specific embodiment, the control system 100 includes a main pipe 101 and a control box 1015, the connecting branch pipe 102 is connected to the main pipe 101, and the main pipe 101 is provided with an air pump 1011 for extracting air and a vacuum sensor 1014 for detecting the vacuum degree, and the air pump 1011 and the vacuum sensor 1014 are respectively electrically connected to the control box 1015. Specifically, the main pipe 101 can be connected to a plurality of connecting branch pipes 102, and each connecting branch pipe 102 is connected to a wall panel body 200 of an assembled exterior wall, so that a plurality of wall panel bodies 200 of the assembled exterior wall are concentrated in the control system 100, so that the user can control the vacuum area of ​​the entire assembled exterior wall through the control box 1015, and the vacuum area in each wall panel body 200 can be monitored and managed through each connecting branch pipe 102, thereby improving the controllability of the thermal insulation performance of the assembled exterior wall. In addition, a main control valve 1012 is provided between the air pump 1011 and the vacuum sensor 1014. The main control valve 1012 can control the state of air extraction of the main pipe 101, and a main check valve 1013 is provided between the main control valve 1012 and the vacuum sensor 1014 to prevent gas backflow. When an emergency occurs (such as maintenance of the assembled exterior wall), it is necessary to close the air extraction pipeline of the entire assembled exterior wall. At this time, the main control valve 1012 can be directly closed to cut off the air extraction of the vacuum area in each wall panel body 200 by the air pump 1011. Of course, the speed of air extraction of the main pipe 101 can also be controlled by the main control valve 1012. In order to prevent the gas from flowing back when the main control valve 1012 is closed, a main check valve 1013 is arranged between the main control valve 1012 and the vacuum sensor 1014 to limit the flow direction of the gas along the main pipe 101 from the wall panel body 200 to the air pump 1011, thereby ensuring that when the main control valve 1012 is closed, the gas will not enter the vacuum area of ​​the wall panel body 200.

[0038] The wall panel structure disclosed in the embodiment of the utility model is provided with a plurality of chambers 201 in the wall panel body 200, and each chamber 201 is interconnected through a transmission conduit 203 located in the wall panel body 200, and a connection port 2032 is provided on the transmission conduit 203, and the connection port 2032 is connected with the control system 100 through a connecting branch pipe 102 located outside the wall panel body 200, so that the control system 100 extracts the air from each chamber 201 through the connecting branch pipe 102, thereby forming a vacuum zone in each chamber 201. As is known to all, a vacuum environment has a high thermal resistance, which can reduce the loss of heat. By extracting the air from each chamber 201 in the wall panel body 200 to form a vacuum zone, the thermal resistance of the wall panel body 200 can be improved, the loss of heat can be reduced, and the weight of the wall panel body 200 can be reduced, which is convenient for the installation of the assembled exterior wall. At the same time, multiple insulation support areas 202 are arranged in the wall panel body 200 to improve the strength of the entire prefabricated exterior wall. Compared with setting the entire wall panel body 200 as a vacuum area, the prefabricated exterior wall structure has higher strength and can prevent wall damage during transportation and installation.

[0039] Compared with the prior art, the wall panel structure disclosed in the embodiment of the utility model is provided with a plurality of chambers 201 in the wall panel body 200, and each chamber 201 is interconnected through a transmission duct 203 located in the wall panel body 200, and the air in each chamber 201 is extracted through the control system 100 to form a vacuum zone in each chamber 201, thereby improving the thermal resistance of the wall panel body 200, reducing the thermal conductivity of the wall panel body 200, achieving energy saving, solving the heat conduction problem existing in the traditional assembled exterior wall structure, and further improving the thermal insulation effect of the assembled exterior wall. At the same time, by providing the thermal insulation support area 202, the strength of the wall panel structure is improved, thereby ensuring the strength of the assembled exterior wall structure.

[0040] It should be noted that the above embodiments are only explained and illustrated for the scenario of prefabricated exterior walls, but are not limited to this scenario. The wall panel structure can also be used for building roof panels, indoor floors, cold storage insulation, equipment insulation and other scenarios, which will not be repeated here.
