Reducing energy consumption during and after the construction process is of great significance to improving the efficiency of buildings. With the development of the construction industry in today's society, the application of thermal insulation walls is becoming more and more extensive, and its performance requirements are becoming higher and higher. The wall self-insulation system refers to a building wall insulation and heat insulation system that uses energy-saving wall materials and supporting special mortars according to a certain building structure to make the thermal performance and other physical performance indicators meet the corresponding standards.

[0032] The embodiment of the utility model provides an ultra-low energy consumption building insulation wall, comprising an insulation base layer 1, a prefabricated board layer 2 and a concrete base layer 3, wherein the concrete base layer 3 is arranged on both sides of the surface of the insulation base layer 1, and the insulation base layer 1 is sandwiched by two layers of concrete base layers 3, and the prefabricated board layer 2 is arranged on the outside of the concrete base layer 3. The insulation base layer 1 adopts a plate material with thermal insulation effect such as a polyurethane board, a polystyrene board, a rock wool board, a foamed ceramic board, etc., and the insulation base layer 1 has a good insulation effect, and can ensure that the insulation wall has ultra-low energy consumption and environmentally friendly pollution-free characteristics. The prefabricated board layer 2 is a plate material such as a cement casting board that is cast in advance, and the concrete base layer 3 is formed by pouring concrete, mortar, cement, etc. on site and solidifying.

[0033] The side surface of the precast panel layer 2 close to the concrete base layer 3 is defined as its inner side surface, and the side surface away from the concrete base layer 3 is defined as its outer surface. A plurality of embedded components are provided on the inner side surface of the precast panel layer 2 close to the concrete base layer 3, each of which includes an embedded chassis 4 and a connector. The embedded chassis 4 is arranged inside the precast panel layer 2, one end of the connector is connected to the embedded chassis 4, and the other end of the connector passes through the inner side surface of the precast panel layer 3 and extends to the concrete base layer 3. Specifically, when preparing the precast panel layer 2, the embedded chassis 4 is embedded into the required depth position (such as the inner middle area) when the precast panel is not completely dry, and the connector is fixed to keep it vertically upward. After the precast panel is completely dry, the embedded chassis can be fixed inside the precast panel layer 2, and the connector passes through its surface.

[0034] In some preferred embodiments of the utility model, in order to strengthen the connection stability between the prefabricated panel layer 2 and the concrete base layer 3, a plurality of first reinforcing ribs 5 and a plurality of second reinforcing ribs 6 are further provided in the prefabricated panel layer 2, wherein the first reinforcing ribs 5 and the second reinforcing ribs 6 intersect vertically and horizontally to form a reinforcing net having a plurality of grids 7, preferably, the reinforcing net is located in the middle position of the prefabricated panel layer 2 to provide sufficient pulling force. The reinforcing net is fixed inside the prefabricated panel layer 2 in the same manner as the embedded chassis 4.

[0035] In the embodiment of the utility model, the first reinforcing rib 5 and the second reinforcing rib 6 are perpendicular to each other, so the formed grid 7 is a square grid; the area of ​​the embedded chassis 4 is larger than the area of ​​the grid 7, so that there is a contact area between the embedded chassis 4 and the first reinforcing rib 5 and the second reinforcing rib 6, so that the first reinforcing rib 5 and the second reinforcing rib 6 are connected to the embedded chassis 4; in addition, from the overall point of view, a plurality of embedded chassis 4 are evenly distributed on the reinforcing net. In specific implementation, a plurality of clamps 8 are provided on the surface of the embedded chassis 4 close to the concrete base layer 3, and the first reinforcing rib 5 can be connected to the embedded chassis 4 by passing the first reinforcing rib 5 through the clamp 8. Similarly, the second reinforcing rib 6 is connected to the embedded chassis 4 through the clamp 8. The center of the embedded chassis 4 coincides with the center of the grid 7, so that the connecting member passes through the grid 7.

[0036] In order to enhance the connection stability between the first reinforcing rib 5 and the second reinforcing rib 6, a locking piece (not shown in the figure) is provided at the intersection of the first reinforcing rib 5 and the second reinforcing rib 6, wherein the locking piece can adopt an existing locking buckle, or can also be locked by wrapping a steel wire, so that the structure of the reinforcing net is more stable.

[0037] The thermal insulation base layer 1 is provided with a plurality of connecting rods 9 distributed in an array, and the two ends of the connecting rods 9 penetrate the concrete base layer 3 and are detachably connected to the connecting piece. In specific implementation, a plurality of through holes distributed in an array are opened on the thermal insulation base layer 1, and the connecting rods 9 are connected to the through holes, and sealing pads 10 are arranged on the outer sides of the two ends of the through holes to prevent concrete mortar from entering the through holes and causing damage to the thermal insulation base layer 1. The two ends of the connecting rod 9 penetrate the sealing pads 10 and are connected to the connecting piece. A spring 11 is sleeved on the outside of the connecting rod 9 located in the through hole, and the two ends of the spring 11 are respectively connected to the sealing pads 10 at the two ends of the through hole. The sealing pads 10 at the two ends of the through hole are connected together by the spring 11 so that they fit tightly to the port of the through hole. When the thermal insulation base layer 1 expands or contracts due to heat, causing the thickness of the layer to increase or decrease, the spring 11 can also use its own elastic deformation to make corresponding adjustments, stretching as the thickness of the layer increases or shrinking as the thickness of the layer decreases, so that the sealing gaskets 10 at both ends of the through hole are always tightly attached to their ports.

[0038] Specifically, the connecting piece includes a threaded column 12 and a threaded sleeve 13, the threaded column 11 is connected to the embedded chassis 4 and passes through the inner side of the prefabricated board layer 2, and the threaded sleeve 13 is threadedly connected to the outside of the threaded column 12; both ends of the connecting rod 9 are provided with external threads adapted to the internal threads of the threaded sleeve 13, so that the end of the connecting rod 9 is threadedly connected to the threaded sleeve 13. Further, the end of the connecting rod 9 is provided with a conical head, so that the end of the connecting rod 9 can be smoothly inserted into the threaded sleeve 13.

[0039] Furthermore, positioning protrusions 14 and positioning recesses 15 for mutual cooperation and connection are respectively provided on the two sides of the thermal insulation base layer 1. An adhesive layer is provided between the positioning protrusions 14 and the positioning recesses 15 of two adjacent thermal insulation base layers 1, wherein the adhesive layer is formed after the adhesive solidifies, and is used to strengthen the connection between the two adjacent thermal insulation base layers 1.

[0040] The preparation principle of the utility model is as follows: first, multiple thermal insulation base layers 1 are spliced ​​together using positioning protrusions 14 and positioning recesses 15, and then the prefabricated board layers 2 are respectively fixed on both sides of the thermal insulation base layer 1, wherein the required thickness of the concrete base layer 3 is reserved between the prefabricated board layer 2 and the thermal insulation base layer 1, and then the end of the connecting rod 9 is aligned with the corresponding threaded sleeve 13, and the threaded sleeve 13 is screwed out from the threaded column 12 for a distance, so that the other end of the threaded sleeve 13 is threadedly connected to the end of the connecting rod 9, thereby connecting the end of the connecting rod 9 to the threaded column 12 through the threaded sleeve 13. After each connecting rod 9 is connected to the connecting piece, concrete mortar is poured into the area between the prefabricated board layer 2 and the thermal insulation base layer 1, and it becomes the concrete base layer 3 after it solidifies. The utility model tightly connects the prefabricated board layers on both sides of the exterior of the thermal insulation base layer with the concrete base layer through pre-embedded components and connectors, thereby enhancing the overall stability of the wall and avoiding separation or cracking between different base layers after long-term use.

[0041] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. A person with ordinary knowledge in the technical field to which the present invention belongs may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the definition of the claims.
