Description

本発明の上記構成によれば、建築物は、柱及び梁が配置された構造躯体領域（β）においては、コンクリート構造体の外断熱工法に従って外断熱され、柱及び梁に囲繞された開口領域（α）は、鋼構造体の外張断熱工法に従って外張断熱され、従って、建築物は、外断熱工法及び外張断熱工法の複合的工法又はハイブリット工法により全体的に断熱される。 According to the above configuration of the present invention, in the structural skeleton area (β) where columns and beams are arranged, the building is externally insulated according to the external heat insulating method of the concrete structure, and the opening area surrounded by the columns and beams. (Α) is externally insulated according to the external heat insulating method of the steel structure, and therefore the building is totally insulated by the combined method of the external heat insulating method and the external heat insulating method or the hybrid method.

また、鋼構造壁部分Ｗａ及び内装壁部分Ｗｂの内部空間は、建築設備用の配線・配管空間として使用し得るので、建築設備工事の施工性が向上する。それにもかかわらず、外壁Ｗの壁厚（図３及び図４に示す壁厚［Ｔ０＋Ｔ１＋Ｔ２］）は、１５０～２５０mmであり、通常のコンクリート壁と壁厚と同等の壁厚に設計し得るので、有効利用可能な室内空間が大きく縮小することはなく、建築意匠設計上の不利は、生じ難い。加えて、鋼構造壁部分Ｗａ及び内装壁部分Ｗｂからなる二重壁構造の外壁Ｗは、所望の耐火性能（１時間耐火）を比較的容易に確保することができる。 Further, since the internal space of the steel structure wall portion Wa and the interior wall portion Wb can be used as a wiring / piping space for building equipment, the workability of building equipment construction is improved. Nevertheless, the wall thickness of the outer wall W (wall thickness [T0 + T1 + T2] shown in FIGS. 3 and 4) is 150 to 250 mm, and the wall thickness can be designed to be the same as that of a normal concrete wall. The effectively usable interior space is not significantly reduced, and disadvantages in architectural design are unlikely to occur. In addition, the outer wall W of the double wall structure composed of the steel structure wall portion Wa and the interior wall portion Wb can relatively easily secure the desired fire resistance (fire resistance for 1 hour).

図１０には、図８に示す外壁構造の応用例として、柱Ｃの柱形輪郭を建築物Ａの外壁面に表出させる形態の外壁構造が示されている。本発明に係る外壁構造は、このように柱形輪郭（及び／又は梁形輪郭）を外壁面に表出せしめる建築意匠設計においても同様に採用することができる。例えば、図１０に示すように柱Ｃが外壁Ｗに対して相対的に平面視外側に突出する設計においては、柱Ｃの外面に沿って断熱材２１を取付けるとともに、ＲＣ用アンカー２９、ブラケット２５、縦胴縁２６’及び留付金具２７を柱Ｃに固定し、外装材２２を留付金具２７に取付ける施工方法が採用される。また、柱Ｃの角部においては、縦胴縁２６”（例えば、C-75×45×15×1.6（mm）のＣ型鋼）をブラケット２５に固定し、Ｌ形断面に成形した外装材２２’を留付金具２７’によって縦胴縁２６”に固定すれば良い。このような外壁構造は、梁Ｂの梁形を外壁面に表出させる形態の外壁構造においても、同様に採用し得る。 As an application example of the outer wall structure shown in FIG. 8, FIG. 10 shows an outer wall structure in which the pillar-shaped contour of the pillar C is exposed on the outer wall surface of the building A. The outer wall structure according to the present invention can also be similarly adopted in an architectural design in which a pillar-shaped contour (and / or a beam-shaped contour) is exposed on an outer wall surface in this way. For example, in a design in which the pillar C projects outward in a plan view relative to the outer wall W as shown in FIG. 10, the heat insulating material 21 is attached along the outer surface of the pillar C, and the RC anchor 29 and the bracket 25 are attached. , The vertical furring strip 26'and the fastener 27 are fixed to the pillar C, and the exterior material 22 is attached to the fastener 27. Further, at the corners of the pillar C, the vertical furring strip 26 ”(for example, C-shaped steel having a size of C-75 × 45 × 15 × 1.6 (mm)) is fixed to the bracket 25, and the exterior material 22 is formed into an L-shaped cross section. 'It may be fixed to the vertical furring strip 26 ' by the fastening metal fitting 27' . Such an outer wall structure can also be similarly adopted in an outer wall structure in which the beam shape of the beam B is exposed on the outer wall surface.
