In a preferred embodiment of the utility model, the assembled lightweight energy-saving expanded perlite composite wallboard is provided and can be divided into three parts, namely a filler wall, an inner heat-insulating composite structure and an outer anti-cracking composite structure. The expanded perlite composite wallboard is mainly used as a filling wall body in an assembly type building, and the filling wall body is not used as a load-bearing wall generally.
As shown in fig. 1, in this embodiment, the fabricated lightweight energy-saving expanded perlite composite wall panel adopts a multi-layer composite organic thermal insulation structure, which uses a concrete frame as a load-bearing structure, the main body of the composite organic thermal insulation structure is a filler wall filled in the concrete frame, the filler wall should completely fill the empty area of the wall panel required to be filled in the concrete frame, and the periphery of the filler wall should be spliced with the edge of the concrete frame to form a continuous closed wall structure. The concrete framework is generally composed of uprights and cross-members, only two of which are shown in fig. 1, namely a first upright a and a second upright B, but this is only by way of illustration and there are actually corresponding cross-members.
In this embodiment, in order to realize better heat preservation performance, the infilled wall is assembled by three-layer composite structure, wherein be located the middle be first polyphenyl board 1, and set up first wire net frame expansion perlite board 2 in the outside of first polyphenyl board 1, set up second wire net frame expansion perlite board 3 in the inboard of first polyphenyl board 1. Polyphenyl board and inflation perlite board all have better thermal insulation performance and fire behavior, and both inside all have the wire net frame moreover, in the wire net frame can imbed stand and crossbeam in advance before concrete frame concreting all around, after concrete placement shaping, the concrete frame can fasten and connect first polyphenyl board 1, first wire net frame inflation perlite board 2 and second wire net frame inflation perlite board 3, guarantee that the infilled wall is more firm with the splice position of concrete frame all around. Finally, the infilled wall is placed in the concrete frame in its entirety, and its indoor side surface should keep the parallel and level with the indoor side surface of concrete frame to follow-up in indoor side sets up corresponding interior heat preservation composite construction.
The inner heat-preservation composite structure and the outer anti-cracking composite structure are respectively arranged on the indoor side and the outdoor side of the filling wall in the concrete frame and respectively play a corresponding function protection role. The inner heat-insulating composite structure mainly plays a role in heat insulation and crack resistance at the indoor side, and the outer crack-resistant composite structure mainly plays a role in crack resistance at the outer side of the external wall panel, so that the service life of the whole external wall panel is prolonged.
In this embodiment, the outer anti-crack composite structure includes a first cement mortar render layer 4 and a first anti-crack mortar layer 5. Wherein, first cement mortar plastering layer 4 sets up in the outdoor side surface of infilled wall, is formed by cement mortar at the coating of 2 outdoor side surfaces of the first wire net frame inflation pearlite board of infilled wall, and in order to guarantee the reliable fixed of cement mortar, still need be connected fixedly through embedded connector 11 between first cement mortar plastering layer 4 and the concrete frame moreover.
