As a result, the main exterior plate 5 is elastically fixed to the predetermined portions of the holders 2 and 9. At this time, since the heat insulating plate 6 of the exterior plate 5 is not present in the holder 2 portion, the attachment can be performed without any problem. Thereafter, in the same manner, the main exterior plate 5 is sequentially hooked and engaged with the holder 2 fixed in advance from the top to the bottom or from the bottom to the top,
Attaching and fixing the exterior plates 5 and 11 to the outer surface of the frame 1,
The exterior plate 5, which constitutes an exterior wall, can also be fitted and fixed by sliding in the longitudinal direction with respect to holders 2 and 11 that have been arranged and fixed in advance. In addition, at each joint in the longitudinal direction of the elongated bodies of the exterior plates 5 and 11, a joint plate of an appropriate width (not shown) is placed on the back side, and its lower end is placed on the back side of the folded portions 5a and 11e of the exterior plates 5 and 11. Fit the formed fitting protrusions 5d and 11d, and connect the upper part to the protrusion 5h of the exterior plate 5 and the exterior plate 11.
By engaging and fixing it to the distal end portion 11b, it is possible to prevent rainwater etc. from entering through the joint.

壁の形成方法は、上述の場合と同様である。 FIG. 5 is an enlarged longitudinal cross-sectional view of a main part of another example of the exterior plate of the present invention, but in this case, the exterior plates 5' and 11' having the same configuration as the exterior plates 5 and 11 described above are shown. , the lower ends of the heat insulating plates 6', 12' are the exterior plates 5', 1
1' is extended to the upper surface of the folded parts 5'a, 11'e, and is adhesively fixed to the upper surface of the folded parts.In this case, the hooked parts of the exterior plates 5', 11' 5f and the part connected thereto are formed intermittently, and the lower corresponding part of the heat insulating plate is cut out to form them intermittently. The method of forming the exterior wall in this case is the same as in the above case.

A gap is created between b, 11a and the hooked portion 5f, and air circulates as shown by arrows A and A in FIG. At the same time, a small amount of air flows through the gaps 7 and 13 through the ventilation holes 6a and 12a of the heat insulating plates 6 and 12.

となつている。つまり外装壁内面、躯体外面等は

ない。 The ventilation through the ventilation holes 6a and 12a is such that a slight convection of air occurs without impairing the heat insulation performance. In other words, the inner surface of the exterior wall, the outer surface of the frame, etc. are not sealed by the heat insulating board, and furthermore, the heat insulating performance is not inhibited by ventilation through the ventilation holes.

させる等の悪影響を防止することができる。 Therefore, a small amount of the air in the gap between the heat insulating board and the exterior board flows into the gap between the heat insulating board and the building frame, dissipating the high temperature in the gap between the heat insulating board and the exterior board due to radiant heat from the outside, especially in the summer. It can prevent the temperature from rising,
In addition, the heat insulating board can block heat transfer between the inside and outside with just a small amount of ventilation, and can maintain heat insulating performance, so the external heat insulation effect, which is effective against radiant heat, can be significantly improved. Furthermore, it is possible to prevent adverse effects such as warping or unevenness on the exterior plate caused by the difference in thermal expansion and contraction between the heat insulating plate and the exterior plate.

ことができる。 In addition, in winter, etc., the gap between the insulation board and the main body of the exterior plate is not filled with saturated moisture, so there is no condensation on the exterior plate surface, which is cooled the most.
In addition, the heat insulating board can block heat transfer between the inside and outside with just a small amount of ventilation, so it can maintain its heat insulating performance and provide both dew condensation prevention and heat insulation effects.
