Preferably, the heat insulation and warm keeping layer is made of a polyphenyl heat insulation board.

The utility model has the advantages that:

1. The triangular fixing frame can improve the stability of the hollow through hole by utilizing the most stable principle of a triangle, so that the firmness of the body is improved, the heat insulation layer adopts an internal heat preservation mode to arrange the heat insulation layer in the body to play a role in keeping warm, the sound insulation layer adopts high-efficiency sound absorption materials such as gradient sound absorption cotton and the like, and a cm or cm sound absorption layer is filled in the middle of the wall body during construction, so that the sound insulation layer has a better sound insulation effect;

2. Through setting up first opening, second opening, can avoid the gliding condition to appear at the in-process of handling at the body handling, thereby reduce the possibility that the incident takes place.
