[0029] With reference to the accompanying drawings, Figure 1 It is a schematic diagram of the front and cross-sectional structure of the EPS cavity module in the prior art; Figure 2 This is a schematic diagram of the main cross-sectional structure of the cavity wall module of the present invention; Figure 3 It is a schematic diagram of the top view of the structure of the cavity wall module of the present invention; Figure 4 It is a bottom view of the structure of the plug board of the present invention.

[0030] In a specific embodiment, Figures 2 to 4 As shown, the cavity wall module of the present invention comprises an inner insulation board 1, an outer insulation board 2 and a plug board 3. The inner insulation board 1 and the outer insulation board 2 are arranged in parallel and aligned up and down, and the plug board 3 is vertically detachably plugged between the inner insulation board 1 and the outer insulation board 2, and more than two plug boards 3 are arranged perpendicular to the inner insulation board 1 in the cavity.

[0031] The plug-in board 3 installed by detachable plug-in is installed between the inner insulation board 1 and the outer insulation board 2. When pouring concrete, the inner connector of the cavity ensures that the inner insulation board 1 and the outer insulation board 2 will not separate. Compared with the fixedly connected steel bars 3' in the prior art, the inner insulation board 1 and the outer insulation board 2 can be transported with the plug-in board 3 removed during transportation, saving the compartment space occupied by the cavity. During construction and installation, the inner insulation board 1 and the outer insulation board 2 are stacked on the lower module, and then the aligned plug-in board 3 is plugged in, and there is no need to insert it from the top of the building reinforcement, which saves time and effort. The cavity wall module of the present invention adopts a split insulation board and a plug-in board, which is easy to transport and install, reduces transportation costs and improves work efficiency.

[0032] In a specific embodiment of the present invention, Figure 2 and Figure 3 As shown, the narrow side walls around the inner insulation board 1 and the outer insulation board 2 are provided with grooves and protrusions for splicing with adjacent cavity modules. The adjacent modules are connected by this mortise and tenon structure, which improves the connection strength and ensures the flatness of the entire wall. The inner side walls of the inner insulation board 1 and the outer insulation board 2 are provided with a plurality of through vertical grooves at intervals. By setting a plurality of the vertical grooves, the bonding area between the cast concrete material and the insulation board is increased, and the connection strength between the insulation board and the concrete material is improved.

[0033] In a specific embodiment of the present invention, Figure 2 and Figure 3 As shown, the cavity wall module of the present invention further includes a plug rod 4, plug pipes 301 are vertically arranged at both ends of the plug board 3, and slots 302 with bottom ends passing through are vertically opened in the middle and bottom of the outer wall of the plug pipe 301. The plug rod 4 is vertically installed on the inner side wall of the inner insulation board 1 or the outer insulation board 2 through a connecting piece, and the plug pipe 301 can be sleeved onto the plug rod 4.

[0034] Specifically, if Figure 4 As shown, a heat insulating layer 303 is compounded on the inner wall of the inserting tube 301 , and the heat insulating layer 303 is a polyethylene plastic layer. The heat insulating layer 303 elastically clamps the outer wall of the inserting rod 4 .

[0035] Specifically, if Figure 2 and Figure 3 As shown, the insertion rod 4 is located in the vertical groove, and the outer wall of the insertion rod 4 does not protrude from the inner wall of the inner insulation board 1 or the outer insulation board 2.

[0036] Specifically, if Figure 2 As shown, the large surface of the plug board 3 is provided with a plurality of reinforcing holes 303, and the reinforcing holes 303 give way to horizontal reinforcing bars. The reinforcing holes 303 can be holes with bottom openings or can be closed rectangular holes.

[0037] By cooperating with the insertion rod 4 and the insertion tube 301, the plug board 3 can be conveniently inserted from top to bottom into the cavity between the arranged inner insulation board 1 and the outer insulation board 2; by arranging a non-through slot 302 at the top to accommodate the connecting piece of the insertion rod 4, the plug board 3 can be limited to prevent it from falling off downward; by compounding the thermal insulation layer 303 on the inner wall of the insertion tube 301, on the one hand, the insertion rod 4 can be elastically clamped to reduce the influence of the matching clearance on the assembly accuracy, and on the other hand, a thermal bridge is formed to reduce the heat transfer path and improve the thermal insulation performance; by arranging the insertion rod 4 in the vertical groove, the protrusion of the insertion rod 4 during transportation is prevented from being scratched and bent.

[0038] In a specific embodiment of the present invention, Figure 2 and Figure 3 As shown, the inner insulation board 1 is specifically made of foamed concrete. A steel frame 101 is also provided inside the inner insulation board 1, and the insertion rod 4 is connected to the steel frame 101 through a connecting piece.

[0039] Specifically, if Figure 2 As shown, the steel skeleton 101 is a steel frame welded with square tubes, and the connecting piece of the inserted rod 4 is directly welded to the outer side wall of the square tube.

[0040] By using foamed concrete to make the internal insulation board 1, compared with the polystyrene foam board used in the prior art, it has certain thermal insulation performance and also has higher strength. When hooks or hanging points are needed for interior decoration, ordinary anchor bolts can be installed without using extended anchor nails to connect to the cavity concrete material; the connecting piece of the plug rod 4 is directly welded to the steel frame 101, which improves the connection strength of the plug rod 4 and reduces the risk of deformation and falling off.

[0041] In a specific embodiment of the present invention, Figure 2 and Figure 3 As shown, the side wall of the inner insulation board 1 facing the interior of the building is prefabricated with a mortar layer 5 and an inner decorative panel 6. The inner decorative panel 6 can be a plastic board or a tile board, and the mortar layer 5 plays the role of leveling and bonding.

[0042] Specifically, a protective film layer 7 is also provided on the outer side of the inner decorative panel 6. The protective film layer 7 is a thin plastic film and is attached to the inner decorative panel 6. After the construction is completed, it can be peeled off.

[0043] By prefabricating the mortar layer 5 and the interior decorative panel 6 in the factory on the side wall of the inner insulation board 1 facing the interior of the building, the construction of the interior surface can be completed at the same time as the main construction is completed, reducing the on-site construction time and labor, and greatly improving the construction efficiency; a protective film layer 7 is used to protect the interior decorative panel 6 to prevent the interior decorative panel 6 from being scratched during the main construction process.

[0044] In a specific embodiment of the present invention, Figure 2As shown, an embedded plate 201 is arranged inside the outer insulation board 2, and the plug rod 4 is connected to the embedded plate 201 through a connecting piece. The embedded plate 201 can be a plastic plate or a carbon steel plate. The outer insulation board 2 adopts a flame retardant polystyrene foam board.

[0045] By adding the embedded plate 201, the connection strength between the insertion rod 4 and the outer insulation board 2 is increased, thereby preventing the insertion rod 4 on the outer insulation board 2 from falling off during transportation or installation.

[0046] In a specific embodiment of the present invention, Figure 2 and Figure 3 As shown, the outer wall of the outer insulation board 2 facing outward is prefabricated with an adhesive layer 8 and an outer facing layer 9. The adhesive layer 8 is specifically made of adhesive mortar, and the outer facing layer 9 can be made of stone board, ceramic tile board or painted metal board.

[0047] By prefabricating the adhesive layer 8 and the exterior finishing layer 9 on the outward side wall of the exterior insulation board 2 in the factory, the exterior finishing construction can be completed at the same time as the main body construction is completed, reducing on-site construction time and labor and improving construction efficiency.

[0048] The use process of the cavity wall module of the present invention: the inner insulation board 1, the outer insulation board 2 and the plug board 3 are loaded and transported to the construction site in a separated state. Because the plug rod 4 is located in the vertical groove, no scratching will occur, and the plug rod 4 generally will not be deformed by impact. When constructing the building wall, first install the relative inner insulation board 1 and outer insulation board 2 above the lower module through the mortise and tenon structure, and pay attention to the alignment of the position of the plug rod 4. Insert the plug board 3, align the plug pipe 301 with the round head at the top of the plug rod 4 from top to bottom, and press down until the top edge of the slot 302 is crimped on the top edge of the connecting piece of the plug rod 4. After completing the installation of all the plug boards 3 on the module, the concrete can be poured in layers, or it can be poured as a whole after all the modules are completed, depending on the construction method. After the main construction of the building is completed, the protective film layer 7 of the inner decorative panel 6 is peeled off, and the seam treatment is performed to complete the interior wall finishing construction. Similarly, after the main construction of the building is completed, it is only necessary to point the adjacent exterior finishing layers 9 to complete the exterior finishing construction, which greatly saves the on-site construction period.

[0049] In summary, the cavity wall module of the present invention is installed between the inner insulation board 1 and the outer insulation board 2 through the plug-in board 3 that can be detachably plugged in. When pouring concrete, it acts as an internal connector in the cavity to ensure that the inner insulation board 1 and the outer insulation board 2 will not separate. Compared with the fixedly connected steel bars 3' in the prior art, the inner insulation board 1 and the outer insulation board 2 can be transported with the plug-in board 3 removed during transportation, saving the compartment space occupied by the cavity. During construction and installation, the inner insulation board 1 and the outer insulation board 2 are stacked on the lower module, and then the aligned plug-in board 3 is plugged in, without having to be inserted from the top of the building reinforcement, saving time and effort. The cavity wall module of the present invention adopts a split insulation board and a plug-in board, which is easy to transport and install, reduces transportation costs and improves work efficiency. In addition, through the cooperation of the plug rod 4 and the plug tube 301, the plug board 3 can be conveniently inserted from top to bottom into the cavity between the arranged inner insulation board 1 and the outer insulation board 2; by setting a non-through slot 302 at the top to accommodate the connecting piece of the plug rod 4, the plug board 3 can be limited to prevent it from falling down; by compounding the heat insulation layer 303 on the inner wall of the plug tube 301, on the one hand, the plug rod 4 can be elastically clamped to reduce the influence of the matching clearance on the assembly accuracy, and on the other hand, a thermal bridge is formed to reduce the heat transfer path and improve the insulation performance; by setting the plug rod 4 in the vertical groove, the plug rod 4 is prevented from being protruded and scratched and bent during transportation. By using foamed concrete to make the inner insulation board 1, compared with the polystyrene foam board used in the prior art, it has a certain insulation performance and a higher strength. When the interior decoration needs a hook or a hanging point, ordinary anchor bolts can be installed, and there is no need to use extended anchor nails to connect to the cavity concrete material; the connecting piece of the plug rod 4 is directly welded to the steel frame 101, which improves the connection strength of the plug rod 4 and reduces the risk of deformation and falling off. By prefabricating the mortar layer 5 and the inner decorative panel 6 on the side wall of the inner insulation board 1 facing the interior of the building, the construction of the inner surface can be completed at the same time as the main construction is completed, reducing the on-site construction time and labor, and greatly improving the construction efficiency; the protective film layer 7 is used to protect the inner decorative panel 6 to avoid scratching the inner decorative panel 6 during the main construction. By adding the embedded plate 201, the connection strength between the plug rod 4 and the outer insulation board 2 is increased, and the plug rod 4 on the outer insulation board 2 is avoided from falling off during transportation or installation. By prefabricating the adhesive layer 8 and the outer finishing layer 9 on the outward side wall of the outer insulation board 2, the construction of the outer finishing can be completed at the same time as the main construction is completed, reducing the on-site construction time and labor, and improving the construction efficiency.
