[0116] like Figure 11 and Figure 12 As shown, this embodiment provides a wall 2, including at least two Figures 4 to 6 The exterior wall composite thermal insulation block structure 1 is recorded in, wherein the first protrusion in one exterior wall composite thermal insulation block structure 1 is embedded in the first groove in another exterior wall composite thermal insulation block structure 1, thereby forming a wall 2.

[0117] Furthermore, in the two exterior wall composite thermal insulation block structures 1 , steel bars 5 are provided in each grouting area.

[0118] In each exterior wall composite insulation block structure 1, the shape of each grouting area is roughly rectangular. When two exterior wall composite insulation block structures 1 are assembled, the two adjacent grouting areas are connected to form a roughly rectangular shape, and two steel bars 5 are arranged in the rectangular grouting area.

[0119] exist Figures 9 to 12 When installing the wall 2, first, the ground 4 is leveled to form a leveling layer 3; finally, after the leveling layer 3 is completed, the exterior wall composite insulation block structure 1 is fixed with mortar to ensure the verticality of the bottom layer of the exterior wall composite insulation block structure 1 before the subsequent blocks can be assembled. After the pouring is completed, the installation of the wall 2 is completed.

[0120] The utility model also has the following advantages:

[0121] 1. It has the effects of heat preservation, fire prevention and sound insulation;

[0122] 2. Prefabricated concrete panels can use industrial waste, which is low-cost, energy-saving and environmentally friendly;

[0123] 3. Light weight and large-size block structure are easy to install and the construction speed is fast;

[0124] 4. After the ground is leveled, it can be assembled directly without mortar masonry, reducing special work and reducing costs;

[0125] 5. The block structure has no extra cavities and low transportation costs.

[0126] The above description is merely a preferred embodiment of the present invention and is intended to be illustrative rather than restrictive of the present invention. Those skilled in the art will appreciate that many changes, modifications, and even equivalents may be made to the present invention within the spirit and scope of the claims, and all of these changes will fall within the scope of protection of the present invention.
