用いる手段があった。[Prior Art] Walls having heat insulating properties are used for walls such as side surfaces, floors, and ceilings of buildings such as general buildings and residences in order to provide heat insulation and prevent condensation. Conventionally, in order to impart heat insulation properties to walls, methods using organic heat insulating materials such as Styroform, inorganic heat insulating materials such as glass wool and rock wool, or inorganic lightweight aerated concrete as one of the constituent layers of the wall were used. There was a means to use it.

Further, although heat insulating materials such as glass wool and raw wool are nonflammable, once water leaks due to rainwater, condensation, etc., it is difficult to remove water and the heat insulating properties are significantly reduced. Also,
The heat insulation properties of conventional lightweight aerated concrete (with a specific gravity of about 0.5 to 0.9), which is made by mixing air bubbles into cement and solidifying it, roughly depend on the amount of air bubbles mixed in, and the compressive strength and If practical strength such as bending strength is taken into account, there is a limit to the increase in the amount of bubbles mixed in.

。FIG. 2 shows an example in which the highly heat-insulating lightweight cellular concrete 1 of the present invention is used in an external heat-insulating wall structure made of cement or concrete. That is, when manufacturing a PC panel 5 in which a suitable exterior material 7 such as tiles is integrally fixed with a hydraulic material 6 such as mortar or concrete, highly insulating lightweight cellular concrete 1 is further placed on top of the PC panel. The PC panels 5 and highly insulating lightweight cellular concrete 1 are placed on the outdoor side, and the structural concrete 8 is placed on the indoor side to form an external insulation wall. This prevents heat transfer between the outside and outside, effectively prevents dew condensation on the inner wall, and improves the constancy of indoor temperature, heat retention, etc., as the concrete frame 8 acts as a heat storage body. In addition, since all of the materials are made of the same material, such as cement or concrete, the adhesion between the materials in each layer is extremely good.
