Claims (5)

It is an external heat insulating structure of a building in which a heat insulating material (23) is interposed between the housing wall (21) and the exterior material (26) on the outdoor side of the housing wall (21), and is based on the base wall (21). The support bolt (22) embedded with (22a) is reinforced by the reinforcing member (27), and the heat insulating material (27) including the reinforcing member (27) is passed through the heat insulating material (23). 23) is pressed against the outdoor side surface of the frame wall (21), and the exterior of the heat insulating material (23) is projected to the front end (22b) of the support bolt (22) through the trunk edge (25). In the configuration to attach the material (26),
The reinforcing member (27) includes a tubular member for inserting the support bolt (22) (34), a plurality of blades body extending from the tubular member (34) to the skeleton wall (21) extends outwardly (35 ), And a fastening nut (39) screwed from the tip of the support bolt (22) in a state where the tip of the blade body (35) is in contact with the wall surface of the housing wall (21). 34) to be fixed by fastening to,
Further, the reinforcing member (27) forms a blade portion (36a) along the outer edge of the blade body (35) to gradually reduce the thickness of the blade body toward the outer edge, When the material (23) is pressed toward the outdoor surface of the housing wall (21), the blade (36a) cuts the heat insulating material (23), thereby causing the blade body (35) to enter the heat insulating material (23). An external heat insulating structure of a building, characterized by being configured as described above. The blade body (35 ) of the reinforcing member (27) includes a shoulder portion (36) extending outward from the cylindrical body (34) and a leg portion (37) extending from the shoulder portion (36) toward the housing wall (21). And at least the outer edge of the shoulder portion (36), the blade portion (36a) is formed to gradually reduce the thickness of the shoulder portion toward the outer edge , the shoulder portion (36) is a cylinder The exterior of the building according to claim 1, characterized in that it is arranged so as to incline downward from the body (34) and the leg (37) is arranged substantially parallel to the axis of the cylinder (34). Thermal insulation structure. The projecting length of the support bolt (22) extending from the outdoor side surface of the housing wall (21) to the tip (22b) is L, and the cylindrical body from the tip of the leg (37) contacting the outdoor side surface of the housing wall (21) The height of the reinforcing member (27) reaching the top end of (34) is H, and the thickness of the heat insulating material (23) is T, so that L> T> H. The exterior heat insulation structure of the building of Claim 1 or 2 to do. The reinforcing member (27) has three blade bodies (35) arranged at equal intervals in the circumferential direction of the cylindrical body (34), and the tips of the leg portions (37) of the three blade bodies (35) are arranged. The external heat insulating structure for a building according to claim 1, 2 or 3, characterized in that it is constructed so as to be supported at three points on the outdoor side surface of the frame wall (21) around the support bolt (22). The reinforcing member (27) is formed by integrally molding the cylindrical body (34) and the blade body (35) by any one of die-cast molding using a metal material, lost wax molding using a metal material, and injection molding using a hard synthetic resin material. The external heat insulating structure for a building according to claim 1, 2, 3, or 4.
