量化及び価格の上昇を来す問題を生じる。When constructing an exterior wall using wood-based panels, in order to have a highly fire-resistant exterior wall structure, it is conceivable to use a highly fire-resistant facing material, such as gypsum board, as the facing material of the wall panel. The use of such facing materials poses the problem of increasing the weight and cost of the wall panel.

ある。The present invention provides an external wall structure with high fire resistance without causing the above-mentioned problems. An exterior wall structure in which mortar is applied to the outdoor side of a single-sided wall panel that is joined together and has a heat insulating material inside through a lath (base material for applying mortar), and between the above-mentioned peripheral frame and the above-mentioned lath. It is characterized in that a fire-resistant gusset (fire-resistant reinforcing backing plate) is arranged, and an air space is formed between the single-sided wall panel and the lath, excluding the fire-resistant gusset.

However, the size of the outer periphery of the fire-resistant gusset 4 is made to approximately match the outer periphery of the outer peripheral frame 2 of the single-sided wall panel 1 so as not to hinder the joining of the single-sided wall panels. ′
The size of the inner periphery is made to match the inner periphery of the inner peripheral frame 2' so as not to adversely affect the opening 10.

Although it varies depending on the degree of filling of the heat insulating material 3, it is approximately fire-resistant gusset) with a thickness of 4.4', fire-resistant gusset) 4.4'
It extends over the entire outdoor side of the single-sided wall panel 1 except for.

のである。Since the outer wall structure of the present invention is configured as described above, most of the heat from the outside can be blocked by the air layer at a high rate, and the amount of heat conducted from the fire-resistant gusset part can also be reduced. Furthermore, by providing a ventilation section, the air heated in the air layer is discharged from the ventilation section into the air layer on the outdoor side of the other single-sided wall panel or outdoors, resulting in a heated single-sided wall panel. If the temperature rise in the air layer on the outside of the building can be alleviated, the fire protection performance can be further improved, which is far higher than when plywood is used as the exterior material. Furthermore, since fire-resistant gussets are used instead of external materials, it is possible to reduce the weight and cost of the panel, and it also has the effect of allowing moisture to be discharged from the vents. and
It is particularly valuable as an exterior wall structure for wooden prefabricated houses.
