The specific thickness can be designed according to the actual building requirements. And the outer blade plate and the inner blade plate are respectively provided with a vertical grouting mother groove 1-4 on the same vertical splicing surface. The utility model adopts a composite process to carry out composite molding on the heat-insulating plate and the inner and outer blades, ensures the connectivity of the heat-insulating plate, forms a heat-insulating integrated structure and replaces the traditional externally-hung heat-insulating apron plate; the utility model adopts factory prefabrication molding, avoids some disadvantages brought by on-site pouring molding firstly, and combines the relevant regulations of the assembly type building; by adopting a grouting female slot technology, when the outer walls are spliced, after the adjacent enclosure plates are correspondingly spliced, a vertical grouting channel 2 is formed, mortar is densely filled in the grouting channel through a grouting process, the adjacent outer wall enclosure plates are bonded and connected through the mortar of the grouting channel, two secondary connecting bodies 3 are formed after the mortar is cured and have strong bonding force, the formed secondary connecting bodies are equivalent to a small structural column and are equivalent to a stressed member, the relative displacement and deformation between the adjacent outer wall enclosure plates caused by external forces such as wind pressure and the like are effectively prevented, the performance requirements of wind pressure resistance and earthquake resistance are met, the construction efficiency is high by matching with the grouting process, the filling compactness of the bonded mortar is high, and no gap exists;

preferably, edge sealing grooves 1-5 which are sunken towards the direction of the grouting mother groove are formed in the peripheral edges of the outer side plate surfaces of the outer blade plate and the inner blade plate, and the edge sealing grooves are of an open structure on the vertical splicing surface side. The edge sealing groove technology is adopted, so that the problem that cracks are easily generated at the joints of the existing internal and external wall enclosure guard plates is solved, namely, the joint strength and the compactness of the joints are improved by filling anti-crack mortar and grid cloth in the edge sealing groove, so that the edge sealing groove has the leveling effect and the waterproof effect, rainwater is prevented from penetrating through the joints, and primary water blocking is formed; the outer wall apron board has higher flatness after being integrally assembled, is favorable for the construction of a decorative surface layer and an inner layer at the later stage, and avoids the phenomena of water leakage, sound insulation and cold and hot bridges of the decorative surface layer due to insufficient flatness of the inner wall and cracking of abutted seams.

In example 2, referring to fig. 6, steel nets 1 to 6 are provided in both the outer blade plate and the inner blade plate. The compression resistance and the bending resistance of the plate body are improved, and the use safety is improved.

In embodiment 3, referring to fig. 7, tie bars 1 to 7 are arranged between the steel nets in the outer blade plate and the inner blade plate, the tie bars penetrate through the heat insulation layer to form a built-in steel skeleton structure, and the combined steel skeleton can also be a steel bar truss structure.
