Abstract

PURPOSE: To attain a harmony in design by providing a balcony type exterior expansion on the outside upper part of an entrance so as to provide a shielding body on the lower surface of an outer peripheral wall, and making the shielding body in the same plain cross-sectional shape as the outer peripheral wall in order to provide a raised shielding body in the inside of the outer peripheral wall. CONSTITUTION: An exterior expansion 2 is expanded semicircularly from a building frame body so that a floor 8 continuously set to a second floor at a middle part, and then a balcony B having the upper part of an outer peripheral wall 2a as a rail is formed, and further, an accommodation part 9 of the shielding body 3 is opened downward in its inside. Also, a semispherically recessed part 11 attached with an entrance light 10 is formed in a hollow shape at an inside lower surface of the outer peripheral wall 2a. Furthermore, a shielding body 3 having substantially the same plain cross-sectional shape as the outer peripheral wall 2a is formed between an lower surface of the outer peripheral wall 2a and the exterior side base surface 13 of an entrance to be subsequently formed into a curved lattice shape, both side end parts of which are joined to a roller 14 rotatably accommodated in the guide rail part 6 of a hollow support body 5. By this constitution an entrance space S can be opened and closed through the elevation of the shielding body 3 to make the entrance open.
