The refractory heat insulating material 6 is used.

本実施例では、このように、溶接箇所wに対応した必要部のみ耐火断熱材6とした断熱材5を接合部材4に充填するものとしたが、例えば角柱状の耐火断熱材6のみで構成された断熱材を充填してもよい。   In this embodiment, the heat insulating material 5 in which only the necessary part corresponding to the welding location w is filled with the heat insulating material 5 is filled in the joining member 4 as described above. You may fill with the heat insulating material made.

なお、図1に示したように、上部の接合部材4に対しては、その下方のフランジ43に柱2の上端が溶接される。その場合、上部の接合部材4内に充填する断熱材5・6は、図示のように、下部の接合部材4内に充填する断熱材5・6と上下逆の関係になる。   As shown in FIG. 1, the upper end of the column 2 is welded to the lower flange 43 of the upper joining member 4. In this case, the heat insulating materials 5 and 6 filled in the upper bonding member 4 are in a reverse relationship with the heat insulating materials 5 and 6 filled in the lower bonding member 4 as shown in the figure.

図3は図1の下部の接合部材4と柱2とその柱2に挿入する断熱材5・6の一例を示したもので、図示のように、柱2に挿入する断熱材5の下端のみ耐火断熱材6としている。
すなわち、予め角柱状の断熱材5の下端を耐火断熱材6で形成しておく。
FIG. 3 shows an example of the joining member 4 and the column 2 at the bottom of FIG. 1 and the heat insulating materials 5 and 6 inserted into the column 2. As shown, only the lower end of the heat insulating material 5 inserted into the column 2 is shown. The fireproof heat insulating material 6 is used.
That is, the lower end of the prismatic heat insulating material 5 is formed in advance with the refractory heat insulating material 6.

このような下端を耐火断熱材6とした角柱状の断熱材5を、矢印で示すように、柱2の内部に挿入してから、柱2の下端を接合部材4のフランジ42に溶接する(図2(a)の溶接箇所w参照)。   A prismatic heat insulating material 5 having such a lower end as a refractory heat insulating material 6 is inserted into the column 2 as indicated by an arrow, and then the lower end of the column 2 is welded to the flange 42 of the joining member 4 ( FIG. 2 (a) shows a welding point w).

Cut in the intersecting orthogonal direction (see dotted line c).
That is, the prismatic heat insulating material 5 is cut in advance as shown by the dotted line c along the orthogonal direction intersecting the fiber direction indicated by the arrow Y direction in the square cross section.

このように、角柱状の断熱材5を、その角形断面において、矢印Y方向で示した繊維方向と交差する直交方向に沿って、点線cで示すように、切断してから、柱2内に挿入するため、断熱材5を繊維方向と交差する直交方向に圧縮変形させることにより、柱2内への断熱材5の挿入がスムーズに行える。   In this manner, the prismatic heat insulating material 5 is cut in the square cross section along the orthogonal direction intersecting the fiber direction indicated by the arrow Y direction, as indicated by the dotted line c, and then into the pillar 2. In order to insert, the heat insulating material 5 can be smoothly inserted into the pillar 2 by compressing and deforming the heat insulating material 5 in the orthogonal direction intersecting the fiber direction.

That is, in the example of the second floor plan as shown, for example, as in the first floor, all the hollow portions of the pillars 2 located on the outer wall side of each living room or the like are filled with the heat insulating materials 5 and 6, respectively.

具体的には、図示の2階プラン例において、201はホール、202は浴室・洗面所・トイレを有するサニタリー、203はバルコニー、204はキッチン、205はリビングルームとダイニングルームの機能を一室に併存させた部屋、206はバルコニー、207は主寝室、208はバルコニーである。
図示例においては、サニタリー202のバルコニー203に沿った外壁側、キッチン204の外壁側、リビングルームとダイニングルーム機能併存の部屋205のバルコニー206に沿った部分を含む外壁側、主寝室207のバルコニー208に沿った部分を含む外壁側の全ての柱2が、中空部に断熱材5・6を充填したものとなっている。
Specifically, in the example of the 2nd floor plan shown in the figure, 201 is a hall, 202 is a sanitary with a bathroom, washroom, and toilet, 203 is a balcony, 204 is a kitchen, and 205 is a living room and dining room function in one room. The coexisting room, 206 is a balcony, 207 is a master bedroom, and 208 is a balcony.
In the illustrated example, the outer wall side along the balcony 203 of the sanitary 202, the outer wall side of the kitchen 204, the outer wall side including the portion along the balcony 206 of the room 205 coexisting with the living room and dining room functions, the balcony 208 of the main bedroom 207 All the pillars 2 on the outer wall side including the portion along the line are filled with the heat insulating materials 5 and 6 in the hollow portion.

なお、図示しないが、接合部材4についても、外壁側に位置する全てに断熱材5・6がそれぞれ充填される。
また、本実施形態の梁3は、上述のように断面コ字状の溝形鋼が用いられているが、外壁側に位置する梁3を、柱2と同様に中空鉄骨とし、その中空部に断熱材5・6を充填してもよい。
その場合、上下何れの接合部材4に対しても、その直交方向に位置する梁接合部45・46の各々に、柱2と同様、予め断熱材5・6を充填した梁3がそれぞれ溶接されるため、角柱状の断熱材5の端部を耐火断熱材6で形成しておく。
In addition, although not shown in figure, also about the joining member 4, all the heat insulating materials 5 and 6 are filled in the outer wall side.
The beam 3 of the present embodiment uses a U-shaped cross section steel as described above, but the beam 3 positioned on the outer wall side is a hollow steel frame like the column 2 and the hollow portion Insulating materials 5 and 6 may be filled.
In that case, the beam 3 preliminarily filled with the heat insulating materials 5 and 6 is welded to each of the beam joints 45 and 46 positioned in the orthogonal direction to any of the upper and lower joining members 4. Therefore, the end of the prismatic heat insulating material 5 is formed with the fireproof heat insulating material 6.

以上、実施形態によれば、建物ユニットの骨組構成部材2・3・4の中空部内に充填した断熱材5・6を、工場での骨組構成部材の溶接の際に焦がすことがない。
これによって、断熱材5・6による断熱効果を十分に発揮できる。
As described above, according to the embodiment, the heat insulating materials 5 and 6 filled in the hollow portions of the frame structural members 2, 3, and 4 of the building unit are not burned when the frame structural members are welded at the factory.
Thereby, the heat insulation effect by the heat insulating materials 5 and 6 can fully be exhibited.

すなわち、柱2または梁3の端部内において、接合部材4に対する溶接箇所wに沿って耐火断熱材6を設けたため、工場での接合部材4に対する溶接の際に柱2または梁3内の断熱材5・6を焦がすことがない。   That is, since the refractory heat insulating material 6 is provided along the welded portion w with respect to the joining member 4 in the end portion of the pillar 2 or the beam 3, the heat insulating material in the pillar 2 or the beam 3 is welded to the joining member 4 at the factory. Do not burn 5.6.

さらに、略ボックス状の接合部材4内において、そのウェブ41、フランジ42・43、鉄板44及び鉄板47の溶接箇所wに沿って耐火断熱材6を設けたため、工場でのウェブ41、フランジ42・43、鉄板44及び鉄板47の溶接の際に接合部材4内の断熱材5・6を焦がすことがない。   Furthermore, since the refractory heat insulating material 6 is provided along the welded portion w of the web 41, the flanges 42 and 43, the iron plate 44 and the iron plate 47 in the substantially box-shaped joining member 4, the web 41 and the flange 42. 43, the iron plate 44 and the iron plate 47 are not burned when the heat insulating materials 5 and 6 in the joining member 4 are welded.

また、角柱状の断熱材5を、その角形断面において繊維方向と交差する直交方向で切断して、柱2または梁3内に挿入するため、断熱材5を繊維方向と交差する直交方向に圧縮変形させることにより、柱2または梁3内への断熱材5の挿入がスムーズに行える。   In addition, the prismatic heat insulating material 5 is cut in the orthogonal direction intersecting the fiber direction in the square cross section and inserted into the column 2 or the beam 3, so that the heat insulating material 5 is compressed in the orthogonal direction intersecting the fiber direction. By deforming, the heat insulating material 5 can be smoothly inserted into the pillar 2 or the beam 3.

そして、建物ユニットの外壁側に位置する柱2、梁3及び接合部材4にのみ中空部内に断熱材5・6を充填するため、特に外壁側で問題となるヒートブリッジ対策が効果的に行え、しかも、外壁側以外の柱2、梁3及び接合部材4には断熱材を必要としないことから、コストを抑制できる。   And since the heat insulating materials 5 and 6 are filled in the hollow portion only in the pillar 2, the beam 3 and the joining member 4 located on the outer wall side of the building unit, the heat bridge countermeasure which becomes a problem particularly on the outer wall side can be effectively performed. And since the heat insulating material is not required for the pillar 2, the beam 3, and the joining member 4 other than the outer wall side, the cost can be suppressed.
