In addition, as a device to make the finding surface of the overhanging part such as a collar thin, for example, it is conceivable to reduce the formation of the beam that supports the overhanging part, but when you want to increase the overhanging dimension of the overhanging part Since it is necessary to form a beam according to the acting load, it is difficult to cope with it. In particular, if the building is an industrialized house, the dimensions and fit of the components used are standardized (standardized) and built based on that standard. It is not realistic to use different beams according to the thickness. On the other hand, according to the building 1 according to the present embodiment, the thickness of the finding surface of the overhanging portion such as the collar portion 13 can be suppressed without changing the beam formation according to the design demand. .

  In the present embodiment, the floor panel 11 is not simply installed on the upper end portion 13d of the nose tip beam 13, but is installed in a state of being dropped inside the nose tip beam 13, so that the slab 5 The height of the upper surface 5a can be suppressed. As a result, it is possible to reduce the bulk of the rising portion 9 that dams rainwater that has fallen on the upper surface 5a of the slab 5, and it becomes easier to clear the oblique line restriction. Moreover, since it leads also to suppressing the height level of the upper end part 7b of the short exterior panel 7, it is effective also in suppressing the thickness of a finding surface.

  Furthermore, in this embodiment, since the drainage metal 41 which covers from the rising part 9 to the exterior panel 7 is provided, it is possible to prevent rainwater from entering. In particular, the drainage metal 41 is provided from the upper end part 9a of the rising part 9 to the exterior. Since it is arrange | positioned along the virtual inclined surface F2 which connects to the upper end part 7b of the panel 7, it becomes easy to arrange | position the draining metal object 41 along the oblique line which receives restrictions, and becomes easy to clear oblique line restrictions.
