せることにより構成されている。 In the second manufacturing method of the heat storage building material manufacturing method of the present invention, the opening end 20A is placed in the extrusion molding die 10A of the inorganic kneaded material extrusion molding device 10 in the extrusion direction (arrow P), as shown in FIG. A double-tubular core body 20 for forming a hollow portion is provided, and when the inorganic kneaded material 1A is extruded from the extrusion molding die 10A, crystalline calcium chloride (CaCl 2 6H 2 O) is produced from the core body 20B. ) or a hydrated salt type latent heat storage material 2 such as crystalline sodium sulfate (Na 2 SO 4 .10H 2 O), and a water-resistant film-forming material 3A such as a thermoplastic synthetic resin that is thermally melted from the surrounding pipe portion 20C. It is constructed by reciprocating the entire core body 20 back and forth along the extrusion direction (arrow P) while simultaneously discharging the core body 20.
そして、上記により押出成形後、成形体は通常

を介して充満された押出成形体１A′が得られる。 In the above, the hydrated salt type latent heat storage material 2 is discharged from the core body 20 into the inorganic kneaded material 1A with the periphery covered with the water-resistant film forming material 3A, and the core body When the core body 20 moves in the opposite direction to the extrusion direction (arrow P) and comes out of the range of the molding die 10A (indicated by the chain line), the hollow hole is not molded by the core body 20. Therefore, as shown in FIG. 6, it has intermittent hollow holes 21, in which the hydrated salt type latent heat storage material 2 is inserted into the water-resistant layer 3.
A filled extrusion molded body 1A' is obtained.
なお、中子体２０と成形ダイ１０Ａとの位置関
係は相対的なものであるから、中子体２０を固定
し、成形ダイ１０Ａを押出方向（矢印Ｐ）に沿つ
て前後に往復動させる構成としても良い。 Note that since the positional relationship between the core body 20 and the molding die 10A is relative, the core body 20 is fixed and the molding die 10A is reciprocated back and forth along the extrusion direction (arrow P). It's good as well.

形したものに比し、上記節の存在により建物全体
の強度の向上も期待出来都合が良い。 In addition, in the case of the second invention, hollow holes 21 having knots are formed in the extrusion molded body 1A', and compared to the case where the hollow extrusion building material is molded by a core body, The presence of knots is convenient because it can be expected to improve the strength of the entire building.

有する潜熱によつて建材自体に蓄熱機能が付与さ

図れまた、耐凍害性も非常に良くなるのである。 As explained above, in this invention, a large number of hydrated salt type latent heat storage materials are dispersed and embedded in the form of bubbles in the cement matrix, which is an inorganic building material, through a water-resistant layer. The latent heat possessed by the hydrated salt type latent heat storage material imparts a heat storage function to the building material itself, which significantly improves the heat insulation properties and also greatly improves the frost damage resistance.

なくすることが出来るといつた効果を有するので
ある。 In addition, since the hydrated salt type latent heat storage material is protected from the cement matrix by a water-resistant layer, it is not only possible to reliably prevent it from penetrating into the cement matrix, but also to prevent it from penetrating into the cement matrix from the outside. Since the water permeable layer prevents the flow of moisture such as rainwater that has penetrated into the material, it has the effect of reducing the inherent water permeability of inorganic building materials. .
