[0002] In the field of construction, wall panels are a commonly used building material. Traditional wall panels often have problems such as poor thermal insulation and flammability, which not only affects the energy-saving effect of the building, but also may bring safety hazards. Therefore, insulated sandwich wall panels with flame retardant functions have begun to appear on the market. The insulated sandwich wall panels are usually composed of two flame retardant exterior wall panels at the front and back, and an insulated sandwich panel in the middle. After the insulated sandwich wall panels are installed flat in the room, they can achieve excellent thermal insulation and flame retardant effects. However, the insulated sandwich wall panels are usually composed of different fireproof materials. When the insulated sandwich wall panels are in a humid environment for a long time, the insulated sandwich panel in the middle is susceptible to moisture and mold, resulting in a decrease in its thermal insulation and flame retardant properties. Therefore, management personnel are required to regularly disassemble the insulated sandwich wall panels to check whether the insulated sandwich panel in the middle is susceptible to moisture and mold. The entire disassembly and assembly steps are not only cumbersome, but also easily destroy the overall sealing effect of the insulated sandwich wall panels, resulting in the insulated sandwich panels being more susceptible to moisture and mold.

[0029] like Figure 2 and Figure 3 As shown, the assembly frame 1 is composed of a front frame 11 and a rear frame 12; the front frame 11 is slidably connected to the front flame retardant plate 2 through a front slide structure 1101; the rear frame 12 is slidably connected to the rear flame retardant plate 3 through a rear slide structure 1201; each strip cover 21 is also rotatably connected to two threaded locking rods 5; the rear ends of the threaded locking rods 5 on the strip cover 21 successively penetrate the front flame retardant plate 2 and the front frame 11, and are fixedly connected to the rear frame 12 through a threaded structure; the insulation core board 4 is clamped between the front frame 11 and the rear frame 12; a hexagonal hole structure 501 is respectively provided at the front end of each threaded locking rod 5.

[0030] The heat-insulating sandwich wall panel of the present invention is mainly composed of an assembly frame 1, a front flame-retardant panel 2, a rear flame-retardant panel 3 and a heat-insulating core panel 4. A fixing tube 41 is provided on the heat-insulating core panel 4. The strip cover 21 on the front flame-retardant panel 2 seals the fixing tube 41 through a plug rod 22 and a sealing ring 23 to form a closed wall panel as a whole. In the installation of the heat-insulating sandwich wall panel of the present invention, it is only necessary to arrange a plurality of the heat-insulating sandwich wall panels in sequence and lay them flat indoors, and fix the rear flame-retardant panel 3 between the indoor ceiling and the floor through bolt fixings, that is, The fixed installation of the thermal insulation sandwich wall panel can be completed. Since the surfaces of the front flame retardant panel 2 and the rear flame retardant panel 3 are coated with a layer of waterproof and moisture-proof hydrophobic coating, the front flame retardant panel 2 and the rear flame retardant panel 3 can isolate most of the external moisture in a humid environment. When the front flame retardant panel 2 and the rear flame retardant panel 3 are in a humid environment for a long time, the hydrophobic coating on the surface of the front flame retardant panel 2 and the rear flame retardant panel 3 will fail in local areas. Therefore, management personnel are required to regularly perform moisture detection on the thermal insulation core panel 4 located inside the thermal insulation sandwich wall panel.

[0031] During the periodic moisture detection of the heat-insulating sandwich wallboard of the present invention, the manager arbitrarily selects a strip cover 21 on the front flame-retardant board 2, and uses the hexagonal wrench carried by him to remove the threaded locking rod 5 from the assembly frame 1 and the front flame-retardant board 2 through the hexagonal hole structure 501 of the threaded locking rod 5, and then pulls out the strip cover 21 after the threaded locking rod 5 is disassembled from the card slot structure 201 of the front flame-retardant board 2. At the same time, the strip cover 21 will drive the plug rod 22 and the sealing ring 23 connected to it to be pulled out from the corresponding fixing tube 41. Since the sealing ring 23 is made of elastic rubber material, even if The diameter of the sealing ring 23 is larger than that of the plug rod 22. The sealing ring 23 can also use its elastic characteristics to be pulled out from the perforated structure 202 of the front flame retardant plate 2 along with the plug rod 22. Then the staff holds the humidity detector and inserts the detection probe of the humidity detector through the perforated structure 202 of the front flame retardant plate 2 and the fixed tube 41 into the fixed hole structure 401 of the insulation core board 4, and performs moisture detection on the corresponding position of the insulation core board 4. During this process, only the local area of ​​the insulation core board 4 aligned with the fixed tube 41 is exposed to the outside air, so only a small amount of external moisture will penetrate into the insulation core board 4.

[0032] When the manager detects that the moisture content in the current insulation core board 4 is high, it means that the insulation core board 4 is damp and moldy and needs to be replaced. At this time, the manager only needs to use the hexagonal wrench he carries to remove all the threaded locking rods 5 on the assembly frame 1 corresponding to the insulation core board 4, and then separate the front frame 11 together with the front flame retardant board 2 from the rear frame 12. After that, the manager can directly pull out the insulation core board 4 that is damp and moldy and remain in the rear frame 12 for replacement. The overall operation is simple and convenient.

[0033] Example 2

[0034] On the basis of Example 1, Figure 1-Figure 9 As shown, in the present embodiment, a water-absorbing cotton ring 42 is fixedly connected to each fixed cylinder 41; each water-absorbing cotton ring 42 is respectively wrapped around the outer surface of the corresponding plug rod 22; a rubber block 43 is inserted into each water-absorbing cotton ring 42; a compression spring 44 is fixedly connected between each rubber block 43 and the corresponding fixed cylinder 41, and the plug rod 22 initially pushes the rubber block 43 outward from the water-absorbing cotton ring 42 to put the compression spring 44 in a compressed state; a cross socket structure 430 adapted to the detection probe structure of the humidity detector is provided in the middle of each rubber block 43.

[0035] After the thermal insulation sandwich wall panel is installed, the water-absorbent cotton ring 42 is tightly attached to the outer surface of the plug rod 22. Even if a small amount of external moisture can pass through the perforated structure 202 of the front flame retardant plate 2 and enter the fixed tube 41 along the outer surface of the plug rod 22, the moisture will be absorbed by the water-absorbent cotton ring 42 wrapped on the outer surface of the plug rod 22, and the rubber block 43 tightly attached between the plug rod 22 and the water-absorbent cotton can also block the small amount of moisture that continues to penetrate, preventing the moisture from further passing through the fixed tube 41 and entering the thermal insulation core panel 4.

[0036] During the regular maintenance and inspection of the thermal insulation sandwich wall panel, when the manager removes the strip cover 21 and the plug rod 22 from the front flame retardant plate 2, in the process of the plug rod 22 leaving the fixed tube 41, the compression spring 44 which is initially in a compressed state pushes the rubber block 43 upward and completely inserts it into the absorbent cotton. Then the manager holds the humidity detector and inserts the cross-shaped structure detection probe of the humidity detector through the perforated structure 202 of the front flame retardant plate 2 and the cross-hole structure 430 of the rubber block 43 into the fixed hole structure 401 of the thermal insulation core plate 4, and performs moisture detection on the corresponding position of the thermal insulation core plate 4. At this time, the detection probe of the humidity detector will be blocked by the rubber block 43 and will not contact the absorbent cotton, thereby avoiding the phenomenon of erroneous detection results due to the detection probe of the humidity detector contacting the moisture absorbed by the absorbent cotton.

[0037] Example 3

[0038] On the basis of Example 1, Figure 1-Figure 9 As shown, in this embodiment, an air pipe 6 is fixedly connected inside the front frame 11 ; a plurality of air jet hole structures 601 are provided on the air pipe 6 ; a plurality of through channel structures 402 aligned with the air jet hole structures 601 are provided on the heat insulation core plate 4 .

[0039] In the installation of the thermal insulation sandwich wall panel, it is necessary to connect the air pipes 6 on the two adjacent thermal insulation sandwich wall panels to each other, and then connect the air pipes 6 on the thermal insulation sandwich wall panel at the end to an external dryer. When the manager uses a handheld humidity detector to detect that the indoor humidity is high, a large amount of water droplets are easily condensed on the surface of the front flame retardant board 2 and the rear flame retardant board 3 in this high humidity environment. The manager turns on the external dryer to transport hot air to the connected air pipes 6. The hot air flows through the jet hole structure 601 of each air pipe 6 and blows into the corresponding thermal insulation core board 4. In the channel structure 402, the hot air flow is diffused to various areas of the insulation core board 4, and the hot air flow heats each insulation core board 4 and the front flame retardant board 2 and the rear flame retardant board 3 connected thereto, thereby accelerating the evaporation rate of condensed water droplets on the surfaces of the front flame retardant board 2 and the rear flame retardant board 3, and avoiding the failure of the hydrophobic coating on the surfaces of the front flame retardant board 2 and the rear flame retardant board 3 due to excessive condensation of water droplets on the surfaces of the front flame retardant board 2 and the rear flame retardant board 3 for a long time, so that a large amount of moisture penetrates the front flame retardant board 2 and the rear flame retardant board 3 and contacts the insulation core board 4, causing the insulation core board 4 to become damp and moldy.

[0040] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
