[0076] Figure 5 It is a schematic diagram of a local structure after fluid casting and molding in an embodiment of the present invention;

[0077] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a cast-type prefabricated wall panel provided by the present invention includes a frame 110 and a first core material 300;

[0078] A first flow channel 310 is provided on the first core material 300 , and a second flow channel 1105 is provided between the first core material 300 and the frame 110 ;

[0079] The fluid 400 flows through the first flow channel 310 and the second flow channel 1105 so that the first core material 300 and the skeleton 110 form an integral structure.

[0080] Specifically, the inner surface wall of the frame 110 is provided with at least one second flow channel 1105, and the second flow channel 1105 is used for fluid circulation;

[0081] The first core material 300 has a plurality of through holes formed inside, and the plurality of through holes form a first flow channel 310 for the fluid 400 to flow;

[0082] The first core material 300 is used to make the wall panel 100 soundproof, heat-insulating, moisture-proof, fire-proof and corrosion-resistant, and is made of any material such as foamed polyurethane, aerogel insulation material, foamed ceramic board, phenolic board, glass wool board, rock wool board, etc.;

[0083] The fluid 400 includes concrete, magnesium sulfate, and magnesium oxysulfate, wherein the concrete is any one of ordinary fine stone concrete, lightweight aggregate concrete, foamed concrete, steel fiber and chopped fiber concrete, and recycled concrete;

[0084] The first core material 300 has holes formed at equal intervals inside, and the holes are circular through holes, so that the fluid 400 can flow through the through holes evenly;

[0085] It is worth noting that the shape of the holes opened on the first core material 300 can be a triangle, a rectangle, an ellipse, etc., or an irregular shape. In addition, the arrangement of the holes opened on the first core material 300 can be a ring array, a rectangular array, or an irregular arrangement. In this embodiment, circular through holes are opened in a rectangular array, which has better stability during use.

[0086] In addition, the second flow channel 1105 can be opened on the outer wall of the first core material 300, can also be opened on the inner surface wall of the frame 110, and can also be opened on the outer wall of the first core material 300 and the inner surface wall of the frame 110 at the same time;

[0087] In the embodiment of the present invention, a plurality of through holes are opened at equal intervals inside the first core material 300, and the plurality of through holes form a first flow channel 310, so that the fluid 400 can flow inside the first core material 300, and a second flow channel 1105 is opened between the first core material 300 and the skeleton 110, so that the fluid 400 can flow between the first core material 300 and the skeleton 110, and finally the fluid 400 fills the first flow channel 310 and the second flow channel 1105. After the fluid 400 is solidified, the first core material 300 and the skeleton 110 are cast into a whole, so as to enhance the overall structural strength of the prefabricated wall panel. The cast wall panel 100 can be used for building a mobile house, and can also be used as a building material for exterior walls, interior walls, floors, ceilings, etc. The cast integrated wall panel 100 has a stable structure, and improves the safety of use while realizing basic functions such as sound insulation, heat preservation and fire prevention.

[0088] Figure 6 A schematic diagram of the structure of a clamping member in an embodiment of the present invention;

[0089] like Figure 6 As shown, the cast-type prefabricated wall panel provided by the present invention further includes a clamping member 200 , and the clamping member 200 is used to limit the first core material 300 inside the frame 110 .

[0090] Figure 7 An exploded view of a clamping member in an embodiment of the present invention;

[0092] Specifically, the clamp 200 is a sheet-like grid structure for fluid 400 to penetrate.

[0093] The first clamp 201, the second clamp 202 and the third clamp 203 are all sheet-like grid structures, having triangular, rectangular, polygonal or irregular grid shape characteristics. Preferably, the first clamp 201, the second clamp 202 and the third clamp 203 are made of a wire mesh with a triangular grid; wherein four second clamps 202 are provided, and the four second clamps 202 are all rectangular and their shape and size match the inner surface wall of the support rod 1101. During installation, the four second clamps 202 are respectively placed parallel to the inner surface walls of the four support rods 1101, and the first core material 300 is placed in the installation space 210 formed between the first clamp 201 and the third clamp 203 after the four second clamps 202 are connected end to end in sequence;

[0094] When producing large-sized prefabricated wall panels, the first clamping member 201 and the third clamping member 203 need to use steel wire mesh, which, in addition to the clamping function, also increases the structural strength of the entire prefabricated wall panel because it is contained inside the casting material; if it is a small-sized prefabricated wall panel, ordinary nylon mesh can be used, which is mainly connected with the second clamping member 202 to form a whole to wrap the first core material 300 and play a clamping role;

[0095] In the embodiment of the present invention, the first core material 300 is enclosed by a sheet-like grid-type first clamp 201, a second clamp 202 and a third clamp 203 to confine the first core material 300 within the skeleton 110. The sheet-like grid-type clamp 200 is made of steel wire, which not only meets the penetration requirements of concrete, but also provides rigid support for the first core material 300, thereby improving the overall strength of the wall panel 100.

[0098] Specifically, the sizes of the first clamp 201 and the third clamp 203 are larger than the inner diameter of the skeleton 110 and smaller than the outer diameter of the skeleton 110. Four second clamps 202 are provided. The four second clamps 202 are all rectangular and their shapes and sizes match the inner surface wall of the skeleton 110. During installation, the third clamp 203 is placed at the bottom of the skeleton 110 so that the upper surface of the third clamp 203 fits the lower surface of the skeleton 110 to provide support for the first core material 300 and the second clamp 202 to be inserted; the four second clamps 202 are placed parallel to the four inner surface walls of the skeleton 110, and the first core material 300 is placed in the four second clamps 202 connected end to end; then the first clamp 201 The first clamp 201 is placed on the upper part of the frame 110 so that the lower surface edge of the first clamp 201 is in contact with the upper surface of the frame 110, and the first clamp 201 is supported by the frame 110; the fixing member 500 passes through the first clamp 201, the first core material 300 and the third clamp 203 in sequence from top to bottom or from bottom to top to fix the three; it is worth noting that the fixing member 500 can also fix the first clamp 201 and the first core material 300, the second clamp 202 and the first core material 300, the third clamp 203 and the first core material 300, the first clamp 201 and the second clamp 202, the second clamp 202 and the third clamp 203, or the first clamp 201 and the third clamp 203 separately;

[0099] In addition, when fixing, the fixing member 500 should not block a large number of through holes opened on the first core material 300 for circulating the fluid 400. In this embodiment, the fixing member 500 is made of steel wire, and the diameter of the steel wire is smaller than the diameter of the through hole;

[0100] In order to improve the overall stability between the components, the clamping member 200 and the support rod 1101, and the first core material 300 and the support rod 1101 can also be fixed by a fixing member 500, which will not be described in detail here.

[0101] In the embodiment of the present invention, during the pre-installation process before pouring concrete, the clamps 200 and the clamps 200 and the first core material 300 are fixed by the fixing members 500 , thereby further improving the integrity of the wall panel 100 .

[0102] Fig. 9 It is a schematic diagram of the structure of the limiting groove in an embodiment of the present invention;

[0103] like Fig. 9 As shown, a limiting groove 1103 is provided on the upper side of the frame 110 along the opening direction of the frame 110, and the limiting groove 1103 is used to limit the first clamping member 201;

[0104] and / or

[0105] A limiting groove 1103 is provided below the frame 110 along the opening direction of the frame 110 , and the limiting groove 1103 is used to limit the third clamping member 203 ;

[0106] The upper surface wall of the frame is provided with a plurality of first anti-slip grooves;

[0107] and / or

[0108] The lower surface wall of the frame is provided with a plurality of first anti-slip grooves.

[0109] Preferably, a plurality of first anti-slip grooves are provided on the upper surface wall of the skeleton, and the plurality of first anti-slip grooves are used to increase the friction between the first clamping piece and the upper surface wall of the skeleton; a plurality of first anti-slip grooves are provided on the lower surface wall of the skeleton, and the plurality of first anti-slip grooves are used to increase the friction between the third clamping piece and the lower surface wall of the skeleton.

[0110] Optionally, a plurality of anti-slip protrusions are provided on the upper surface wall of the skeleton, and the plurality of anti-slip protrusions form a first anti-slip pattern for increasing the friction between the first clamping piece and the upper surface wall of the skeleton; a plurality of anti-slip protrusions are provided on the lower surface wall of the skeleton, and the plurality of anti-slip protrusions form a first anti-slip pattern for increasing the friction between the third clamping piece and the lower surface wall of the skeleton; the first anti-slip pattern is composed of a plurality of strip-shaped protrusions or a plurality of strip-shaped grooves, and the plurality of strip-shaped protrusions and the plurality of strip-shaped grooves are spread along the length direction of the skeleton; a plurality of first anti-slip patterns are provided at the bottom of the limiting groove 1103; a plurality of first anti-slip patterns are provided at the inner side of the support rod 1101 along the length direction and at the position where the second clamping piece 202 fits together.

[0111] Specifically, the skeleton 110 includes a plurality of support rods 1101, and the upper wall and / or the lower wall of each support rod 1101 is provided with at least one first protrusion 1102 along the height direction of the support rod 1101, and the first protrusions 1102 are sequentially connected end to end to form a limiting groove 1103 for limiting the first clamping member 201 and / or the second clamping member 202; the inner surface wall of each support rod 1101 is provided with at least one second protrusion 1104 along the thickness direction of the support rod 1101, and the second clamping member 202 is tightly fitted with the second protrusion 1104, so that a second flow channel is formed between the second clamping member 202 and the support rod 1101, and the second flow channel is used for the fluid 400 to flow;

[0112] Specifically, the four support rods 1101 are connected end to end through angle brackets to form a rectangular frame 110. The upper walls of the four support rods 1101 are each provided with a first protrusion 1102 upwardly along the height direction of the support rod 1101. The length of the first protrusion 1102 is equal to the length of the support rod 1101. Therefore, there are four first protrusions 1102 on the top of the rectangular frame 110. The four first protrusions 1102 are connected end to end in sequence to form a rectangular limiting groove 1103. The rectangular limiting groove 110 3 matches the shape and size of the first clamping member 201, is used to place the first clamping member 201, and plays the role of limiting the position of the first clamping member 201 to prevent the first clamping member 201 from being displaced along the thickness direction of the support rod 1101; it is worth noting that the height of the first protrusion 1102 is slightly greater than the height of the first clamping member 201, and the limiting groove 1103 formed by the four first protrusions 1102 connected end to end in sequence is also used to prevent the fluid 400 from overflowing and facilitate the formation of a horizontal surface after the fluid material is solidified;

[0113] Furthermore, the first protrusion 1102 is arranged at the edge of the support rod 1101, and its outer wall is in the same plane as the outer wall of the support rod 1101.

Therefore, there are four first protrusions 1102 at the bottom of the rectangular skeleton 110. Like the four first protrusions 1102 provided on the top of the support rod 1101, the four first protrusions 1102 located at the bottom of the skeleton 110 are connected end to end in sequence to form a rectangular limiting groove 1103. The positioning groove 1103 matches the shape and size of the first clamping member 201, and is used to place the third clamping member 203, and plays a role in limiting the position of the third clamping member 203, preventing the third clamping member 203 from being displaced along the thickness direction of the support rod 1101; it is also worth noting that the height of the first protrusion 1102 is slightly greater than the height of the third clamping member 203, and the limiting groove 1103 formed by the four first protrusions 1102 at the bottom of the frame 110 connected end to end in sequence is also used to prevent the fluid 400 from overflowing;

[0115] Furthermore, the first protrusion 1102 located at the lower part of the skeleton 110 is arranged at the lower edge of the support rod 1101, and its outer wall is in the same plane as the outer wall of the support rod 1101. The first protrusion 1102 and the support rod 1101 are integrally formed. The first protrusion 1102 is a long strip with a length consistent with the length of the support rod 1101 and a thickness much smaller than the thickness of the support rod 1101.
