In this case, the slab of the main body portion and the slab of the external passage portion There is a problem that the thermal insulation effect is relatively lowered due to the thermal bridge phenomenon, and the defects in the insulation insulation work can be directly connected to the condensation.

In order to overcome such a problem, there has been proposed a conventional method in which a heat insulation method is interposed between an inner wall connected to a slab of a building body and an outer wall connected to a slab of an outer passage, and a heat insulating material is interposed between the inner wall and the outer wall (Japanese Unexamined Patent Application Publication No. 10-2001-0377134, FIG. 2, published on May 15, 2001), a precast floor slab of a specific shape such as a truss girder having a complicated structure and protruding upward is used, And the reinforcing bars projected from the precast wall are required to be connected to each other.

As another typical conventional method, a method using an insulating material such as 'isokorb' manufactured by SCHOCK BAUTEILE has been used frequently but it is applied mainly to balconies or eaves or parapets which are less burdened with load, And is not applied to a structure such as a public hallway or an outer corridor having a large area and weight, and the above-mentioned trade name 'isokorb' is composed of a central heat insulating block and a reinforcing bar extending through the heat insulating block EP 0 892 118 A1, EP 0 848 119 A1 (published on Jun. 17, 1998), EP 0 892 118 A1 (published on Apr. 18, 1998), and the like.
