SOLAR RADIATION HEAT CONTROL STRUCTURE

PROBLEM TO BE SOLVED: To enable solar radiation heat admitting indoors to be reduced and also to enable a heat quantity radiated to the exterior via a window part from the indoors to be reduced.SOLUTION: A solar radiation heat control structure 10 comprises an exterior wall 16 having window parts 18A and 18B and an opening-closing ventilating opening 26, a steel earthquake resisting wall 40 arranged on the indoor 14R side of the exterior wall 16 and opposed to the window parts 18A and 18B, an outside sliding screen 60X arranged on the exterior wall 16 side more than the steel earthquake resisting wall 40 and switchable to a shielding state of covering an outer surface 42X of the steel earthquake resisting wall 40 with relative movement with respect to the steel earthquake resisting wall 40 and an exposure state of exposing the outer surface 42X of the steel earthquake resisting wall 40 by being shifted in the width direction of the steel earthquake resisting wall 40 and an inside sliding screen 60Y arranged on the indoor 14R side more than the steel earthquake resisting wall 40 and switchable to a shielding state of covering an inner surface 42Y of the steel earthquake resisting wall 40 with the relative movement with respect to the steel earthquake resisting wall 40 and an exposure state of exposing the inner surface 42Y of the steel earthquake resisting wall 40 by shifting in the width-direction of the steel earthquake resisting wall 40.SELECTED DRAWING: Figure 2 【課題】本発明は、室内に入る日射熱を低減可能とし、かつ、室内から窓部を介して外部へ放熱される熱量を低減可能にすることを目的とする。【解決手段】日射熱制御構造１０は、窓部１８Ａ，１８Ｂと、開閉する換気口２６と、を有する外壁１６と、外壁１６の室内１４Ｒ側に配置され、窓部１８Ａ，１８Ｂと対向する鋼製耐震壁４０と、鋼製耐震壁４０よりも外壁１６側に配置され、鋼製耐震壁４０との相対移動に伴って鋼製耐震壁４０の外面４２Ｘを覆う遮蔽状態と、鋼製耐震壁４０の横幅方向にずれて当該鋼製耐震壁４０の外面４２Ｘを露出させる露出状態とに切り替えられる外側障子６０Ｘと、鋼製耐震壁４０よりも室内１４Ｒ側に配置され、鋼製耐震壁４０との相対移動に伴って鋼製耐震壁４０の内面４２Ｙを覆う遮蔽状態と、鋼製耐震壁４０の横幅方向にずれて当該鋼製耐震壁４０の内面４２Ｙを露出させる露出状態とに切り替えられる内側障子６０Ｙとを備える。【選択図】図２
