However, since the side surface of the connecting bracket and the side surface of the column are substantially flush, the heat insulating material attached to the side surface of the connecting bracket protrudes from the side surface of the column by the thickness. When the heat insulating material protrudes from the side surface of the column, when the outer wall panel used in a well-known panel method is joined to the side surface of the column, or when the exterior material is attached to the side surface of the column, the outer wall panel and the exterior material are insulated.

The floor panel 13 is constructed by assembling the eaves into a rectangular frame shape, assembling a reinforcing bar material inside the frame body, and further bonding a face material made of plywood or the like on the upper surface of the frame body.

前記半土台１２と床パネル１３の接合部の上方には、前記連結金具１が配置されており、この連結金具１の孔３にアンカーボルト１４の上端部が下方から挿通されている。アンカーボルト１４の上端部には、上下二つのナット１６，１７が螺合されており、下のナット１７は連結金具１の下壁の下面に当接し、上のナット１６は同下壁の上面に当接している。下のナット１７は、アンカーボルト１４の上端部を連結金具１の孔３に挿通する前に、該アンカーボルト１４に螺合され、上のナット１６はアンカーボルト１４の上端部を連結金具１の孔３に挿通した後に、連結金具１の開口部１ｂから挿入して螺合されている。そして、スパナやレンチ等の工具を前記開口部１ｂから連結金具１内に挿入して上のナット１６を締め付けるとともに、連結金具１の下壁と床パネル１３との間の隙間から挿入して下のナット１７を締め付けることによって、連結金具１がアンカーボルト１４の上端部に固定されている。   The connecting fitting 1 is disposed above the joint between the semi-base 12 and the floor panel 13, and the upper end of the anchor bolt 14 is inserted into the hole 3 of the connecting fitting 1 from below. Upper and lower nuts 16 and 17 are screwed to the upper end portion of the anchor bolt 14, the lower nut 17 abuts on the lower surface of the lower wall of the connection fitting 1, and the upper nut 16 is the upper surface of the lower wall. Abut. The lower nut 17 is screwed into the anchor bolt 14 before the upper end portion of the anchor bolt 14 is inserted into the hole 3 of the connecting fitting 1, and the upper nut 16 is connected to the upper end portion of the anchor bolt 14 of the connecting fitting 1. After being inserted into the hole 3, it is inserted through the opening 1b of the connecting fitting 1 and screwed. Then, a tool such as a spanner or a wrench is inserted into the connection fitting 1 from the opening 1b and the upper nut 16 is tightened, and the tool is inserted through the gap between the lower wall of the connection fitting 1 and the floor panel 13. By tightening the nut 17, the connecting fitting 1 is fixed to the upper end portion of the anchor bolt 14.

連結金具１の上壁には、棒状でかつ断面正方形状の構造部材としての柱２０が設置されている。連結金具１の孔２には固定ボルト２１が上方から挿通されており、当該固定ボルト２１の下端部にはナット２２が連結金具１の開口部１ｂから挿入されて螺合されている。また、柱２０の下端面の中央部には、取付孔２３が柱２０の軸方向に延在して形成されている。取付孔２３は固定ボルト２１より若干大径に形成されるとともに、接着剤が充填されている。
そして、取付孔２３に連結金具１の上壁から突出する固定ボルト２１が挿入されることによって、柱２０の下端面に連結金具１が取り付け固定されている。なお、前記接着剤が硬化した後、ナット２２を締め付けることによって柱２０の下端面に連結金具１が強固に固定されている。 A column 20 as a structural member having a rod shape and a square cross section is installed on the upper wall of the connection fitting 1. A fixing bolt 21 is inserted from above into the hole 2 of the connecting fitting 1, and a nut 22 is inserted into the lower end portion of the fixing bolt 21 from the opening 1 b of the connecting fitting 1 and screwed. A mounting hole 23 is formed in the center of the lower end surface of the column 20 so as to extend in the axial direction of the column 20. The mounting hole 23 is formed to have a slightly larger diameter than the fixing bolt 21 and is filled with an adhesive.
Then, by inserting the fixing bolt 21 protruding from the upper wall of the connection fitting 1 into the attachment hole 23, the connection fitting 1 is attached and fixed to the lower end surface of the column 20. In addition, after the said adhesive agent hardens | cures, the connection metal fitting 1 is firmly fixed to the lower end surface of the pillar 20 by tightening the nut 22.

前記連結金具１は、その横断面が正方形状に形成されたものであり、その横断面の大きさが柱２０の正方形状の横断面より小さくなっている。そして、連結金具１は柱２０の下端面に同軸に固定されている。これによって、連結金具１の全ての側面１ａ，１ａ，１ｃ，１ｃが柱２０の、前記側面１ａ，１ａ，１ｃ，１ｃと同じ方向を向くそれぞれの側面２０ａより内側に位置している。そして、これら側面１ａ，１ａ，１ｃ，１ｃがそれぞれ取付面１ａ，１ａ，１ｃ，１ｃとなっている。   The connecting metal fitting 1 is formed in a square cross section, and the size of the cross section is smaller than the square cross section of the column 20. The connecting fitting 1 is fixed coaxially to the lower end surface of the column 20. Thereby, all the side surfaces 1a, 1a, 1c, and 1c of the connecting metal fitting 1 are located on the inner side of the side surfaces 20a of the column 20 facing the same direction as the side surfaces 1a, 1a, 1c, and 1c. These side surfaces 1a, 1a, 1c, and 1c are mounting surfaces 1a, 1a, 1c, and 1c, respectively.

前記連結金具１の側面１ａ，１ａ，１ｃ，１ｃと、柱２０の４つの側面２０ａを延長した面との間に、第１断熱材２５が設けられている。つまり、連結金具１の取付面１ａ，１ａ，１ｃ，１ｃには、第１断熱材２５，２５が取り付けられている。
第１断熱材２５は平板状の断熱材２５ａ，２５ａを平面視Ｌ型に接合して形成されたものであり、断熱板２５ａの上下の長さは、連結金具１の上下の長さより長くなっている。つまり、断熱材２５ａは、連結金具１の上下の長さに、連結金具１の下壁の下面と床パネル１３の上面との間の隙間Ｓの上下の長さを加えた長さとなっている。
また、断熱材２５ａの幅は、連結金具１の側面１ａ，１ｃの幅と等しくなっている。 A first heat insulating material 25 is provided between the side surfaces 1 a, 1 a, 1 c, 1 c of the connecting metal 1 and a surface obtained by extending the four side surfaces 20 a of the column 20. That is, the first heat insulating materials 25 and 25 are attached to the attachment surfaces 1a, 1a, 1c, and 1c of the connection fitting 1.
The first heat insulating material 25 is formed by joining flat heat insulating materials 25 a and 25 a in an L shape in a plan view, and the vertical length of the heat insulating plate 25 a is longer than the vertical length of the connection fitting 1. ing. That is, the heat insulating material 25 a has a length obtained by adding the vertical length of the gap S between the lower surface of the lower wall of the coupling metal 1 and the upper surface of the floor panel 13 to the vertical length of the coupling metal 1. .
Further, the width of the heat insulating material 25 a is equal to the width of the side surfaces 1 a and 1 c of the connection fitting 1.

そして、連結金具１の互いに直交する一方の側面（取付面）１ａ，１ｃに、一方のＬ型の第１断熱材２５がそれらの上端を合せて接着剤によって取り付けられ、互いに直交する他方の側面（取付面）１ａ，１ｃに、他方のＬ型の第１断熱材２５がそれらの上端を合せて接着剤によって取り付けられている。
したがって、連結金具１の開口部１ｂ，１ｂは第１断熱材２５の断熱材２５ａ，２５ａによって塞がれている。
また、第１断熱材２５は、連結金具１の取付面１ｃ（１ａ）と、柱２０の側面２０ａの段差分の厚さに形成されており、これによって、第１断熱材２５はその表面を柱２０の側面２０ａと面一にして取り付けられている。
また、連結金具１の下端から下方に突出する第１断熱材２５の下端部は半土台１２および床パネル１３の上面に当接されている。 Then, one L-shaped first heat insulating material 25 is attached to one side surface (mounting surface) 1a, 1c of the connecting metal fitting 1 orthogonal to each other with their upper ends aligned with each other, and the other side surface orthogonal to each other. (Mounting surfaces) The other L-shaped first heat insulating material 25 is attached to the mounting surfaces 1a and 1c by an adhesive with their upper ends aligned.
Accordingly, the openings 1 b and 1 b of the connecting metal fitting 1 are closed by the heat insulating materials 25 a and 25 a of the first heat insulating material 25.
Moreover, the 1st heat insulating material 25 is formed in the thickness for the level | step difference of the attachment surface 1c (1a) of the connection metal fitting 1, and the side surface 20a of the pillar 20, Thereby, the 1st heat insulating material 25 has the surface. The column 20 is mounted so as to be flush with the side surface 20a.
Further, the lower end portion of the first heat insulating material 25 protruding downward from the lower end of the connection fitting 1 is in contact with the upper surfaces of the semi-base 12 and the floor panel 13.

前記連結金具１の内部には、開口部１ｂから第２断熱材２６が充填されている。この第２断熱材２６はロックウールやガラスウール等で形成された柔軟なものであり、開口部１ｂを前記第１断熱材２５によって塞ぐ前に、開口部１ｂから連結金具１の内部に充填されている。
さらに、連結金具１の下壁の下面と床パネル１３の上面との間の隙間Ｓには、第３断熱材２７が充填されている。この第３断熱材２７はロックウールやガラスウール等で形成された柔軟なものであり、隙間Ｓを前記第１断熱材２５によって塞ぐ前に該隙間Ｓに充填されている。
なお、第２断熱材２６および第３断熱材２７を、連結金具１の内部および隙間Ｓに充填する場合、一方の第１断熱材２５を取り付けた後充填し、その後、他方の第１断熱材２５を取り付けるようにする。 The connecting metal fitting 1 is filled with a second heat insulating material 26 from the opening 1b.
