Further, the grouting holes are distributed in square grids.
Further, the horizontal and vertical hole spacing H between the grouting holes is 30cm.
The beneficial effects of the utility model are as follows: the utility model comprises an AAC outer sheet wallboard, high thermal resistance low density polyurethane foaming, an AAC inner sheet wallboard, an interface mortar leveling layer and a facing layer, wherein the polyurethane board is blocked on the side surface of the inner sheet wallboard and the outer sheet wallboard, rectangular grid distributed grouting holes are arranged on the AAC inner sheet wallboard, the horizontal and vertical hole spacing between the grouting holes is 30cm, and the filled high thermal resistance low density polyurethane is compact and uniform and is applied to the outer wall of an ultra-low energy consumption building.
Compared with the existing hard foam polyurethane heat-insulating outer wall, the heat-insulating outer wall has the following structure:
1) All the operations are completed indoors and are not influenced by outdoor weather factors.
2) The hanging basket and the bracket of the outer wall are not needed, and the construction potential safety hazard is low.
3) The grouting holes are used for grouting polyurethane foaming with high thermal resistance and low density, flatness is not required to be considered, the generation of construction waste is reduced while compactness is guaranteed, a large number of liquid beads are avoided, air pollution is avoided, and the heat preservation effect is good.
For steel wire mesh combination heated board cast in situ concrete heat preservation outer wall, it has:
1) The self-compaction concrete pouring is not needed, a large amount of slurry is not easy to segregate and generate, and pollution is avoided while the strength of the frame node is influenced.
2) The construction is carried out without special fasteners, the difficulty is low, the construction can be carried out alternately, and key circuits are not occupied.
3) The AAC plate can be used for sizing, so that the loss is small, and the construction is convenient.
4) The polyurethane has good heat preservation integrity and air tightness.
