The technical scheme adopted by the utility model for realizing the aim is as follows: a composite heat-insulating prefabricated outer leaf wallboard comprises a concrete outer leaf board and a heat-insulating board compounded on the inner surface of the concrete outer leaf board; a reinforcing mesh is poured inside the concrete outer leaf plate; a plurality of mutually matched connecting pieces in the width direction are uniformly welded on two sides of the reinforcing steel bar net rack in the width direction; the whole connecting piece is of a plate-shaped structure, one end of the connecting piece is provided with a hook-shaped protrusion part, and the other end of the connecting piece is provided with a hook-shaped groove which is matched with the hook-shaped protrusion part and used for inserting and combining the hook-shaped protrusion part; the outer page or leaf board outside is stretched out to the concrete to collude the form bulge of the connecting piece of concrete outer page or leaf board one side, and the outer mouth of colluding form recess and the outer side parallel and level of concrete outer page or leaf board of the connecting piece of opposite side.
Furthermore, a plurality of U-shaped connecting ribs are welded on two sides or one side of the metal net rack in the width direction, bent portions of the U-shaped connecting ribs are upwards bent and protruded, grooves are formed in positions corresponding to the side edges of the heat insulation board, and the bent portions of the U-shaped connecting ribs are exposed in the grooves.
Furthermore, a concrete boss is arranged at the center of one end of the concrete outer leaf plate in the length direction, and double M-shaped connecting steel bars are poured inside the concrete boss.
The principle and the beneficial effects of the utility model are as follows: the composite heat-insulating prefabricated outer-leaf wallboard integrates stress and heat insulation, and a method of pouring after a template is arranged on the inner side of the outer-leaf body can greatly improve the construction efficiency, save a large amount of manpower and material resources, enable the wall body to have better strength and heat-insulating durability than the existing heat-insulating wall body, and facilitate decoration due to good appearance flatness of the surface of the wall body; the utility model has little pollution to the environment because of adopting the prefabricated wall board without building rubbish basically.

Detailed Description
The present invention will be further described with reference to the accompanying drawings, wherein the technical solutions in the embodiments of the present invention are clearly and completely described, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments.
As shown in fig. 1-4, the composite heat-insulating prefabricated outer leaf wallboard of the embodiment includes a concrete outer leaf 2 and a heat-insulating board 1 compounded on the inner surface of the concrete outer leaf; a metal net frame is poured inside the concrete outer-leaf plate 2, and the metal net frame comprises a reinforcing mesh 8; a plurality of connecting pieces 7 which are matched with each other are uniformly welded on two sides of the reinforcing steel bar net rack in the width direction; the connecting piece 7 is integrally of a plate-shaped structure, one end of the connecting piece is provided with a hook-shaped convex part 7-1, and the other end of the connecting piece is provided with a hook-shaped groove 7-2 which is matched with the hook-shaped convex part 7-1 and is used for inserting and combining the hook-shaped convex part; the hook-shaped bulge 7-1 of the connecting piece at one side of the concrete outer leaf plate 2 extends outwards to the outside of the concrete outer leaf plate, and the outer opening of the hook-shaped groove 7-2 of the connecting piece at the other side is flush with the outer side surface of the concrete outer leaf plate. The horizontal connection in the outer page direction of the prefabricated wall panels is achieved by the combination of fig. 4, 7-1 and 7-2.
As shown in fig. 2, in this embodiment, a plurality of U-shaped connecting ribs 3 are welded on one side of the metal net rack in the width direction, bent portions of the U-shaped connecting ribs 3 are bent and protruded upwards, a groove 5 is formed in a position corresponding to a side edge of the heat insulation board 1, and the bent portions of the U-shaped connecting ribs 3 are exposed in the groove; the U-shaped connecting ribs exposed in the grooves facilitate the connection of special tie bars (replacing split bolts of the template). The connection solves the problem of partial horizontal connection in the direction perpendicular to the outer page, and the U-shaped connecting ribs 3 and the hook-shaped grooves 7-2 are welded together to ensure the accuracy in the process of factory prefabrication.
As shown in fig. 1-2, in this embodiment, a concrete boss 4 is disposed at a center of one end of the concrete outer leaf 2 in the length direction, and a double M-shaped connecting steel bar 6 is poured inside the concrete boss 4; the top bending part of the double M-shaped connecting steel bars 6 is exposed on the top surface of the concrete boss 4; when the wall body is constructed, the double M-shaped connecting steel bars exposed on the top surface of the concrete boss 4 can be used for connecting floor plates and can also be used for connecting steel bar cages of concrete beams when the concrete beams need to be poured, and can also be used as hoisting hook points. The connection can be considered as a prefabricated anchor, which acts to anchor and carry the load of the outer leaf wall.
