Thereby, for example, the anchor bolts 14, 14, 15 having a diameter of 12 mm protrude between the floor panel 12 and the semi-bases 13, 13 and above.
As shown in FIG. 3, the floor panel 12 is formed by joining and integrating core materials 122, 123...

さて、本発明によれば、上述したコーナー柱30を布基礎10側に固定するにあたって、柱30の下端部に壁厚よりも薄い角柱形状をもつ小形部31を形成し、この小形部31を小形部と等しい厚さの固定金物20で布基礎10上の半土台13,13および床パネル12上に固定するとともに、壁パネル40と小形部31とで形成される凹部32、33に断熱材50,51を装填するように構成している。   Now, according to the present invention, when fixing the above-described corner column 30 to the fabric foundation 10 side, a small portion 31 having a rectangular column shape thinner than the wall thickness is formed at the lower end portion of the column 30, and this small portion 31 is formed. The fixing hardware 20 having a thickness equal to that of the small portion is fixed on the semi-bases 13 and 13 and the floor panel 12 on the cloth foundation 10, and the heat insulating material is provided in the concave portions 32 and 33 formed by the wall panel 40 and the small portion 31. 50 and 51 are loaded.

ここで、上述した小形部31は、柱30の下端部において該柱30の周囲2面を軸線方向に沿って所定深さだけ切り欠くことにより壁厚より薄い細角柱形状の小形部31として形成されている。   Here, the above-described small portion 31 is formed as a small rectangular column-shaped small portion 31 that is thinner than the wall thickness by notching two peripheral surfaces of the column 30 by a predetermined depth along the axial direction at the lower end portion of the column 30.

また、固定金物20は、布基礎10上に載せられた床(床パネル12や半土台13,13による)上に、基部に設けた側面視四角形状を呈する箱状部21を固定するとともに、該箱状部21から前記小形部31の厚さ分の間隔をおいて延設された一対の支持片22,23を備えて構成されている。   Further, the fixed hardware 20 fixes a box-shaped portion 21 having a quadrangular shape in a side view provided on the base portion on the floor (by the floor panel 12 and the semi-bases 13 and 13) placed on the cloth foundation 10, and A pair of support pieces 22 and 23 are provided so as to extend from the box-shaped portion 21 with an interval corresponding to the thickness of the small portion 31.

固定金物20の基部の箱状部21の内部には、布基礎11側から突設されたアンカーボルト15を固定するためのナット固定空間が形成されている。
なお、図中26はアンカーボルト15を締結するナットである。また、27は支持片22,23を柱30の小形部31に固定するための釘である。
A nut fixing space for fixing the anchor bolt 15 protruding from the cloth base 11 side is formed inside the box-shaped portion 21 at the base of the fixed hardware 20.
In the figure, reference numeral 26 denotes a nut for fastening the anchor bolt 15. Reference numeral 27 denotes a nail for fixing the support pieces 22 and 23 to the small portion 31 of the column 30.

これを詳述すると、前記コーナー柱30用の固定金物20は、図1ないし図4に示すように、壁厚と等しい太さを有する角材からなるコーナー柱30よりも細く形成されている小形部31に対応して、たとえば90mm角の大きさをもつ箱状部21と、この箱状部21上から上方に延設された隣接する2辺から垂直に各々起設されて一体化した、例えば、幅50mm程度で高さ200mm程度の平板による2片の支持片22,23とを備えている。   More specifically, as shown in FIG. 1 to FIG. 4, the fixed hardware 20 for the corner pillar 30 is a small portion formed thinner than the corner pillar 30 made of square material having a thickness equal to the wall thickness. Corresponding to 31, for example, a box-shaped part 21 having a size of 90 mm square and the two adjacent sides extending upward from the box-shaped part 21 are vertically installed and integrated, for example, , And two support pieces 22 and 23 by a flat plate having a width of about 50 mm and a height of about 200 mm.

ここで、上述した箱状部21は、水平方向の対向する面がねじ締め用の開口面とされている箱体形状で形成され、その上面部であって、前記開口面とは対応しない閉塞面の上部に前記支持片22,23が対向するようにして垂直方向に延設されている。   Here, the above-described box-shaped portion 21 is formed in a box shape in which a horizontally opposed surface is an opening surface for screw tightening, and is an upper surface portion that does not correspond to the opening surface. The support pieces 22 and 23 are extended in the vertical direction so as to face the upper part of the surface.

また、上述した箱状部21および支持片22,23は、たとえば厚さ9mm程度の鉄板により折り曲げ形成されるもので、箱状部21の底板の中央には、例えば、直径30mm程度の円形の取付孔(図2参照)が形成される一方、支持片22,23には、例えば、横2列で上下方向に6個ずつによる計12個の孔部が形成されている。   The box-shaped portion 21 and the support pieces 22 and 23 described above are formed by bending, for example, an iron plate having a thickness of about 9 mm, and a circular plate having a diameter of about 30 mm is formed at the center of the bottom plate of the box-shaped portion 21. While the mounting holes (see FIG. 2) are formed, the support pieces 22 and 23 are formed with a total of 12 holes, for example, 6 in the horizontal direction and 6 in the vertical direction.

他方、コーナー柱30の下端部は、図1、図2に示すように、その2面が所定長さにわたって切り落とされており、これにより小形部31が形成されている。そして、この小形部31の2面に前記支持片22,23が釘27で固定され、この固定金物20がアンカーボルト15、ナット26で布基礎11側に固定されることにより、該柱30を布基礎11上の床パネル12上に立設させた状態で支持固定するようになっている。   On the other hand, as shown in FIG. 1 and FIG. 2, the bottom surface of the corner column 30 has its two surfaces cut off over a predetermined length, whereby a small portion 31 is formed. Then, the support pieces 22 and 23 are fixed to the two surfaces of the small portion 31 with nails 27, and the fixing hardware 20 is fixed to the cloth base 11 side with the anchor bolts 15 and nuts 26. It is supported and fixed in a state where it stands on the floor panel 12 on the fabric foundation 11.

以上の構成によれば、壁厚と等しい柱30の下端部に該壁厚よりも薄い小形部31を形成し、この小形部31を、該小形部31と等しい厚さの固定金物20で布基礎11側に固定するとともに、壁40と小形部31とで形成される凹部32,33内に、前記小形部31の外側と下端部に組み付けられている固定金物20を覆うような大きさと形状で形成されている断熱材50,51を装填するように構成しているから、簡単な構成であるにもかかわらず、以下に述べる種々優れた効果を奏する。   According to the above configuration, the small portion 31 thinner than the wall thickness is formed at the lower end portion of the column 30 equal to the wall thickness, and the small portion 31 is clothed with the fixed hardware 20 having the same thickness as the small portion 31. The size and shape are fixed to the base 11 side and cover the fixed hardware 20 assembled to the outside and the lower end of the small portion 31 in the recesses 32 and 33 formed by the wall 40 and the small portion 31. Since the heat insulating materials 50 and 51 formed in (1) are loaded, the following excellent effects can be obtained despite the simple structure.

すなわち、柱30の布基礎11側への結合用として固定金物20を用いた場合の熱橋対策、特に断熱材50,51の施工をきわめて容易に行える。   That is, it is possible to very easily carry out countermeasures against the thermal bridge when the fixed hardware 20 is used for coupling the pillar 30 to the cloth foundation 11 side, in particular, the heat insulating materials 50 and 51.

特に、柱30の下端部に小形部31により形成される凹部32,33を利用して断熱材50,51を装填して配設するようにしているから、従来のように柱や床パネルの周囲の平らな面に、断熱材を取り付ける場合等のように断熱材を手で押さえるといった面倒な作業は不要であり、断熱材50,51等の組み付け作業がきわめて簡単に行えるものであり、作業性の面で優れている。   In particular, since the heat insulating materials 50 and 51 are loaded and arranged using the concave portions 32 and 33 formed by the small portion 31 at the lower end portion of the column 30, as in the conventional case, the columns and floor panels are arranged. There is no need for the troublesome work of holding the heat insulating material by hand, such as when attaching the heat insulating material to the surrounding flat surface, and the work of assembling the heat insulating materials 50, 51, etc. can be performed very easily. Excellent in terms of sex.

これを詳述すると、本発明のように、柱30の下端部に設けた小形部31に対して固定金物20を固定し、これにより柱30の下端部において小形部31の周囲で隣接して配置される壁パネル40との間に形成される凹部32,33内に断熱材50,51を装填して組み込むようにしているから、断熱材50,51を所定位置に位置決めして装填することが可能となる。   More specifically, as in the present invention, the fixed hardware 20 is fixed to the small portion 31 provided at the lower end portion of the column 30, so that the lower end portion of the column 30 is adjacent to the periphery of the small portion 31. Since the heat insulating materials 50 and 51 are loaded and incorporated in the recesses 32 and 33 formed between the wall panel 40 and the wall panel 40 to be arranged, the heat insulating materials 50 and 51 are positioned and loaded at predetermined positions. Is possible.

また、この断熱材50,51の装填作業中にこれらの断熱材50,51を手で押さえて落下を防止するといった面倒な作業は不要となる。
特に、断熱材50,51等の形状を、凹部32,33の形状よりも大きくし、装填時において、圧縮した状態でそれぞれの凹部32,33内に装填すれば、より一層落下しにくくなるもので、その実用上での利点は大きい。
In addition, the troublesome work of holding the heat insulating materials 50 and 51 by hand during the loading operation of the heat insulating materials 50 and 51 to prevent them from falling is unnecessary.
In particular, if the shape of the heat insulating materials 50, 51, etc. is made larger than the shape of the recesses 32, 33 and loaded into the respective recesses 32, 33 in a compressed state, it will be more difficult to drop. The practical advantages are great.

なお、本発明は上述した実施の形態で説明した構造には限定されず、柱30の固定構造を構成する各部の形状、構造等を適宜変形、変更し得ることは言うまでもない。
たとえば布基礎11上への床パネル12等の配設構造、壁パネル40等の配設構造としては種々の変形例が考えられる。
Note that the present invention is not limited to the structure described in the above-described embodiment, and it is needless to say that the shape and structure of each part constituting the fixing structure of the pillar 30 can be appropriately modified and changed.
For example, various modifications can be considered as the arrangement structure of the floor panel 12 and the like on the cloth foundation 11 and the arrangement structure of the wall panel 40 and the like.

また、柱30として、コーナー柱を例示したが、これに限定されない。さらに、固定金具20としても、箱状部31と支持片32,33からなるほぼコ字状を呈する金具に限らず、適宜の変形例が考えられる。   Moreover, although the corner pillar was illustrated as the pillar 30, it is not limited to this. Furthermore, the fixing bracket 20 is not limited to a substantially U-shaped bracket made up of the box-shaped portion 31 and the support pieces 32 and 33, and an appropriate modification can be considered.
