[0002] Building energy conservation refers to reducing energy consumption as much as possible while meeting the same needs or achieving the same purpose during the production of building materials, construction and use of houses and structures. Good thermal insulation performance of the building's exterior walls is the core of achieving building energy conservation.

[0003] Realizing the integration of wall insulation and structure, ensuring the insulation has the same lifespan as the building, and promoting the innovation of new wall materials and the pace of building energy conservation are not only major innovations in traditional building design and construction methods, but also meet the needs of building energy conservation development, and meet the needs of continuously improving building standardization, factory production of components, mechanized construction and efficient management, improving labor productivity, reducing project costs, improving project quality, and realizing the sustainable development of green buildings.

[0004] At present, the domestic energy-saving and heat-insulating exterior wall methods are: traditional lightweight masonry wall + external insulation (autoclaved aerated concrete wall masonry, external wall plastering, external wall insulation, thin plastering, and finally external decorative surface layer). The blocks used in the autoclaved aerated concrete wall masonry are autoclaved aerated concrete composite self-insulating blocks. In addition, new material walls also have disadvantages such as high cost, low material penetration rate and limited production.

[0005] Among them, the insulation block is the basic unit that constitutes the insulation wall. However, in the prior art, after the insulation block is installed, the insulation wall not only needs to be insulated, but also has many construction processes and a long construction period. In addition, the design life of the external insulation is short. At the same time, some external walls are easy to fall off after insulation, and the insulation effect is low, which increases the use cost and reduces the service life of the insulation block.

[0011] Further optimization: the first reinforcement component includes a first steel mesh, which is made by bundling first cold-rolled ribbed steel bars arranged in a criss-cross pattern, and the first steel mesh is integrally cast in the inner panel.

[0012] Further optimization: the second reinforcement component includes a second steel mesh, which is made by bundling second cold-rolled ribbed steel bars arranged in a criss-cross pattern, and the second steel mesh is integrally cast inside the outer panel.

[0013] Further optimization: the thermal insulation material layer is tightly wrapped by the inner panel, the outer panel and the two connecting ribs, and the thermal insulation material layer is integrally connected with the corresponding inner panel, the outer panel and the two connecting ribs respectively.

[0014] Further optimization: the third reinforcement component includes a plurality of corrugated steel bar trusses placed inside the connecting ribs, and the plurality of corrugated steel bar trusses are arranged in parallel and at intervals along the width direction of the corresponding connecting ribs.

The ELC polystyrene particle lightweight aggregate concrete has the advantages of light weight, high strength, and thermal insulation.

[0019] The supporting frame in the composite self-insulating building block of the present invention forms a thermal insulation structure, and the thermal insulation material filled in the supporting frame enables the wall to have light weight, high strength, thermal insulation, sound absorption and sound insulation performance.

[0020] The utility model has a composite self-insulating building block with high-efficiency thermal insulation material inside and has mature technology, which can completely solve the potential safety hazard of falling off and cracking of the outdoor thermal insulation layer, is conducive to extending the service life of the thermal insulation building block, and solves the worries of property maintenance and repair.
