本発明は、耐火壁構造及び耐火壁構造の施工方法に関する。 The present invention relates to a refractory wall structure and a method for constructing a refractory wall structure.

特許文献1の耐火被覆構造では、外壁に近接している鉄骨柱にコ字状に折曲げられた耐火ボードが巻付けられ、鉄骨柱の三面が覆われている。 In the fireproof coating structure of Patent Document 1, a fireproof board bent in a U shape is wound around a steel frame column adjacent to the outer wall, and three surfaces of the steel frame column are covered.

特開2015−63877号公報JP-A-2015-63877

一対の柱を連結するラチス材と外壁材との間に、吹付けを行わずに断熱材を設けた耐火壁構造がある。この耐火壁構造を施工する場合には、ラチス材で連結された一対の柱を立設した後で、断熱材をラチス材の屋外側に配置してから、外壁材を設ける施工方法が用いられている。しかし、この施工方法では、外壁材が設けられる前に断熱材を配置するので、外壁材の配置を考慮しながら断熱材を配置しなくてはならず、断熱材を配置する作業が煩雑になる。つまり、断熱材を有する耐火壁構造において、施工性を向上させるには、改善の余地がある。 There is a refractory wall structure in which a heat insulating material is provided between the lattice material connecting the pair of columns and the outer wall material without spraying. When constructing this refractory wall structure, a construction method is used in which a pair of columns connected by a lattice material are erected, a heat insulating material is placed on the outdoor side of the lattice material, and then an outer wall material is provided. ing. However, in this construction method, since the heat insulating material is arranged before the outer wall material is provided, the heat insulating material must be arranged while considering the arrangement of the outer wall material, and the work of arranging the heat insulating material becomes complicated. .. That is, in a refractory wall structure having a heat insulating material, there is room for improvement in order to improve workability.

本発明は、断熱材を有する耐火壁構造において、施工性を向上させることが目的である。 An object of the present invention is to improve workability in a refractory wall structure having a heat insulating material.

第1態様に係る耐火壁構造は、建物の外壁材に対する屋内側で該建物の内外方向と交差する交差方向に並んで立設された一対の鉄骨柱と、前記内外方向に貫通した貫通部を前記鉄骨柱とで形成すると共に、前記一対の鉄骨柱を連結するラチス材と、前記外壁材と前記ラチス材との間に配置され前記交差方向に延在されると共に弾性変形可能とされた断熱部と、該断熱部と一体に設けられると共に該断熱部から外側へ延出され前記一対の鉄骨柱に取付けられる取付部とを備え、前記貫通部を通過可能に形成された断熱材と、前記一対の鉄骨柱に前記取付部を取付ける取付手段と、を有し、前記取付手段は、前記一対の鉄骨柱とで前記取付部を挟むことで前記取付部を取付ける永久磁石を有するThe fireproof wall structure according to the first aspect comprises a pair of steel columns erected side by side in an intersecting direction intersecting the inside and outside directions of the building on the indoor side with respect to the outer wall material of the building, and a penetrating portion penetrating in the inside and outside directions. A heat insulating material formed of the steel frame columns and connecting the pair of steel frame columns, and a heat insulating material which is arranged between the outer wall material and the lattice material and extends in the intersecting direction and is elastically deformable. A heat insulating material formed integrally with the heat insulating portion and extending outward from the heat insulating portion and attached to the pair of steel frame columns so as to pass through the penetrating portion, and the heat insulating material. possess a mounting means for mounting said mounting portion to a pair of steel column, the said attachment means comprise a permanent magnet for mounting said mounting portion by sandwiching the mounting portion between the pair of steel columns.

第1態様に係る耐火壁構造では、外壁材に対する屋内側で立設された一対の鉄骨柱が、ラチス材で連結されている。そして、ラチス材と鉄骨柱とで貫通部が形成されている。なお、ラチス材とは、柱や梁などの間にジグザグ状に渡された補強材のことを意味する。この状態において、断熱材が、ラチス材に対する屋内側から貫通部を通過して外壁材とラチス材との間に配置される。さらに、断熱材の取付部が、取付手段によって一対の鉄骨柱に取付けられる。このように、外壁材、一対の鉄骨柱及びラチス材が設けられた後で、ラチス材に対する屋内側から、ラチス材と外壁材との間に断熱材を取付ける作業を行える。このため、外壁材が配置される前に、外壁材の配置を考慮しながら断熱材の配置を行う必要がなくなる。つまり、断熱材の配置作業を屋内側から簡単に行うことができるので、断熱材を有する耐火壁構造において、施工性を向上させることができる。
また、本態様では、取付部が、永久磁石と鉄骨柱とで挟まれることで、永久磁石と鉄骨柱との引合う力によって、鉄骨柱に取付けられる。言い換えると、鉄骨柱に取付部を接触させた状態で永久磁石を取付部に近づけるだけで、永久磁石と鉄骨柱とが引合って取付部が取付けられるので、一対の鉄骨柱に断熱材を取付ける作業を簡単に行うことができる。なお、永久磁石とは、外部から磁場や電流の供給を受けずに、磁石としての性質を保持し続ける物体を意味する。
In the refractory wall structure according to the first aspect, a pair of steel columns erected indoors with respect to the outer wall material are connected by a lattice material. Then, a penetrating portion is formed by the lattice material and the steel frame column. The lattice material means a reinforcing material that is passed in a zigzag shape between columns and beams. In this state, the heat insulating material is arranged between the outer wall material and the lattice material through the penetrating portion from the indoor side with respect to the lattice material. Further, the attachment portion of the heat insulating material is attached to the pair of steel columns by the attachment means. In this way, after the outer wall material, the pair of steel columns, and the lattice material are provided, the work of attaching the heat insulating material between the lattice material and the outer wall material can be performed from the indoor side with respect to the lattice material. Therefore, it is not necessary to arrange the heat insulating material while considering the arrangement of the outer wall material before the outer wall material is arranged. That is, since the work of arranging the heat insulating material can be easily performed from the indoor side, the workability can be improved in the refractory wall structure having the heat insulating material.
Further, in this embodiment, the attachment portion is sandwiched between the permanent magnet and the steel frame column, and is attached to the steel frame column by the attractive force between the permanent magnet and the steel frame column. In other words, simply by bringing the permanent magnet close to the mounting part with the mounting part in contact with the steel frame column, the permanent magnet and the steel frame column are attracted to the mounting part, so the heat insulating material is attached to the pair of steel frame columns. The work can be done easily. The permanent magnet means an object that keeps its properties as a magnet without being supplied with a magnetic field or an electric current from the outside.

第2態様に係る耐火壁構造には、前記外壁材、前記鉄骨柱及び前記断熱材に接触し、前記外壁材と前記鉄骨柱との間で断熱する補助断熱材が設けられている。 The refractory wall structure according to the second aspect is provided with an auxiliary heat insulating material that comes into contact with the outer wall material, the steel frame column, and the heat insulating material to insulate between the outer wall material and the steel frame column.

第2態様に係る耐火壁構造では、外壁材と鉄骨柱との間に補助断熱材が配置される。さらに、補助断熱材は、外壁材とラチス柱との間に配置された断熱材と接触する。これにより、外壁材と一対の鉄骨柱との間の空間に、断熱材及び補助断熱材が連続して配置されることになるので、補助断熱材を配置しない構成に比べて、耐火壁構造の断熱性能を高めることができる。 In the fireproof wall structure according to the second aspect, an auxiliary heat insulating material is arranged between the outer wall material and the steel frame column. In addition, the auxiliary insulation comes into contact with the insulation disposed between the outer wall material and the lattice columns. As a result, the heat insulating material and the auxiliary heat insulating material are continuously arranged in the space between the outer wall material and the pair of steel frame columns. Insulation performance can be improved.

態様に係る耐火壁構造の施工方法は、第1態様又は様に記載の耐火壁構造の施工方法であって、前記断熱材を、前記ラチス材に対する屋内側から前記貫通部を通過させて前記外壁材と前記ラチス材との間に配置する第1工程と、前記外壁材と前記ラチス材との間に配置された前記断熱材の前記取付部を、前記永久磁石を用いて前記一対の鉄骨柱に取付ける第2工程と、を有する。 Construction method of the refractory wall structure in accordance with the third aspect is a method of installing the refractory wall structure according to the first aspect or the second state like, the heat insulating material, the through portion from the indoor side with respect to the lattice material Using the permanent magnet , the first step of passing the outer wall material and arranging the lattice material and the attachment portion of the heat insulating material arranged between the outer wall material and the lattice material are used. It has a second step of attaching to the pair of steel columns.

態様に係る耐火壁構造の施工方法では、外壁材に対する屋内側で立設された一対の鉄骨柱が、ラチス材で連結されている。この状態において、断熱材が、ラチス材に対する屋内側から貫通部を通過されて外壁材とラチス材との間に配置される(第1工程)。さらに、断熱材の取付部が、取付手段によって一対の鉄骨柱に取付けられる(第2工程)。このように、外壁材、一対の鉄骨柱及びラチス材が設けられた後で、ラチス材に対する屋内側から、ラチス材と外壁材との間に断熱材を取付ける作業を行える。このため、外壁材が配置される前に、外壁材の配置を考慮しながら断熱材の配置を行う必要がなくなる。つまり、断熱材の配置作業を屋内側から簡単に行うことができるので、断熱材を有する耐火壁構造において、施工性を向上させることができる。 In the method of constructing the refractory wall structure according to the third aspect, a pair of steel columns erected indoors with respect to the outer wall material are connected by a lattice material. In this state, the heat insulating material is placed between the outer wall material and the lattice material through the penetrating portion from the indoor side with respect to the lattice material (first step). Further, the heat insulating material attachment portion is attached to the pair of steel columns by the attachment means (second step). In this way, after the outer wall material, the pair of steel columns, and the lattice material are provided, the work of attaching the heat insulating material between the lattice material and the outer wall material can be performed from the indoor side with respect to the lattice material. Therefore, it is not necessary to arrange the heat insulating material while considering the arrangement of the outer wall material before the outer wall material is arranged. That is, since the work of arranging the heat insulating material can be easily performed from the indoor side, the workability can be improved in the refractory wall structure having the heat insulating material.

以上説明したように、本発明に係る耐火壁構造及び耐火壁構造の施工方法では、断熱材を有する耐火壁構造において、施工性を向上させることができる。 As described above, in the refractory wall structure and the method of constructing the refractory wall structure according to the present invention, the workability can be improved in the refractory wall structure having a heat insulating material.

<鉄骨柱>
図1に示す鉄骨柱22及び鉄骨柱24は、外壁パネル16に対するY方向の屋内側で、X方向に所定の間隔(長さL1)をあけて並び、Z方向に立設されている。また、鉄骨柱22及び鉄骨柱24は、一例として、角形鋼で構成されており、それぞれ大きさ及び形状が同様とされている。鉄骨柱22及び鉄骨柱24と外壁パネル16とのY方向の間隔の長さをL2とする。
<Steel column>
The steel frame columns 22 and 24 shown in FIG. 1 are arranged indoors in the Y direction with respect to the outer wall panel 16 at a predetermined interval (length L1) in the X direction, and are erected in the Z direction. Further, the steel frame column 22 and the steel frame column 24 are made of square steel as an example, and have the same size and shape, respectively. Let L2 be the length of the distance between the steel column 22 and the steel column 24 and the outer wall panel 16 in the Y direction.

鉄骨柱22は、Y方向の屋外側(外壁パネル16側)の側面22Aと、屋内側の側面22Bと、X方向の一方側(鉄骨柱24と対向する側)の側面22Cと、他方側(鉄骨柱24側とは反対側)の側面22Dとを有する。側面22Aから側面22BまでのY方向の長さをL3とする。また、側面22Cから側面22DまでのX方向の長さをL4とする。 The steel frame column 22 has a side surface 22A on the outdoor side (outer wall panel 16 side) in the Y direction, a side surface 22B on the indoor side, a side surface 22C on one side (the side facing the steel frame column 24) in the X direction, and the other side (the side facing the steel frame column 24).

It has a side surface 24D (on the side facing the steel column 22). The length from the side surface 24A to the side surface 24B in the Y direction is L3. Further, the length from the side surface 24C to the side surface 24D in the X direction is L4. The distance (length L1) between the steel frame column 22 and the steel frame column 24 means the length in the X direction from the side surface 22C to the side surface 24D.

図2に示す鉄骨柱22及び鉄骨柱24のZ方向の上端部には、既述のように、連結部材37が設けられている。連結部材37は、図示しないボルト及びナットにより、建物10の天井梁15に締結固定されている。また、鉄骨柱22及び鉄骨柱24のZ方向の下端部は、既述のように、建物10の基礎梁13に設けられた図示しないアンカーにボルトを用いて締結固定されている。 As described above, the connecting member 37 is provided at the upper end portion of the steel frame column 22 and the steel frame column 24 shown in FIG. 2 in the Z direction. The connecting member 37 is fastened and fixed to the ceiling beam 15 of the building 10 by bolts and nuts (not shown). Further, as described above, the lower ends of the steel column 22 and the steel column 24 in the Z direction are fastened and fixed to anchors (not shown) provided on the foundation beam 13 of the building 10 by using bolts.

<ラチス材>
図2に示すラチス材26は、一例として、丸鋼を曲げ加工することで形成されている。ラチス材26の形状は、Y方向から見た場合に、Z方向に連続する台形波状とされている。具体的には、ラチス材26は、鉄骨柱22側でZ方向に延びる複数の直線部26Aと、鉄骨柱24側でZ方向に延びる複数の直線部26Bと、直線部26A、26Bの端部に連続し直線部26A、26Bに対して斜め方向に延びる複数の傾斜部26Cとを有する。直線部26Bは、直線部26AよりもZ方向に短い。
<Lumber>
The lattice material 26 shown in FIG. 2 is formed by bending round steel as an example. The shape of the lattice material 26 is a trapezoidal wavy shape continuous in the Z direction when viewed from the Y direction. Specifically, the lattice material 26 includes a plurality of straight line portions 26A extending in the Z direction on the steel frame column 22 side, a plurality of straight line portions 26B extending in the Z direction on the steel frame column 24 side, and end portions of the straight line portions 26A and 26B. It has a plurality of inclined portions 26C that are continuous with the straight portions 26A and 26B and extend in an oblique direction with respect to the straight portions 26A and 26B. The straight portion 26B is shorter in the Z direction than the straight portion 26A.

直線部26Aには、ラチスコマ27が設けられている。ラチスコマ27は、一例として、X方向を板厚方向とする金属板状に形成されており、直線部26AのZ方向の中央部に対して鉄骨柱22側に配置されている。ラチスコマ27のZ方向の長さは、直線部26AのZ方向の長さよりも短い。ここで、ラチスコマ27が側面22Cに接合され、直線部26Bが側面24Dに接合されることにより、ラチス材26が鉄骨柱22と鉄骨柱24とをX方向に連結している。 A lattice coma 27 is provided on the straight line portion 26A. As an example, the lattice coma 27 is formed in a metal plate shape with the X direction as the plate thickness direction, and is arranged on the steel frame column 22 side with respect to the central portion of the straight line portion 26A in the Z direction. The length of the lattice piece 27 in the Z direction is shorter than the length of the straight line portion 26A in the Z direction. Here, the lattice piece 27 is joined to the side surface 22C, and the straight line portion 26B is joined to the side surface 24D, so that the lattice material 26 connects the steel frame column 22 and the steel frame column 24 in the X direction.

ラチス材26と鉄骨柱22とで囲まれた空間部、及びラチス材26と鉄骨柱24とで囲まれた空間部を貫通部31と称する。言い換えると、ラチス材26は、貫通部31を有する。貫通部31は、Y方向から見た場合に台形状の孔部として視認される部位である。また、貫通部31は、ラチス材26をY方向に貫通した部位である。 The space portion surrounded by the lattice material 26 and the steel frame column 22 and the space portion surrounded by the lattice material 26 and the steel frame column 24 are referred to as a penetration portion 31. In other words, the lattice material 26 has a penetrating portion 31. The penetrating portion 31 is a portion that is visually recognized as a trapezoidal hole when viewed from the Y direction. Further, the penetrating portion 31 is a portion that penetrates the lattice material 26 in the Y direction.

ラチス材26では、直線部26A、26Bと傾斜部26Cとが交わる部位である屈曲部が塑性ヒンジ部とされている。この塑性ヒンジ部は、地震力などの外力が作用した場合に曲げ変形して振動エネルギーを吸収するエネルギー吸収部に相当し、荷重により断面が降伏することで塑性ヒンジが形成される部位である。また、ラチス材26では、ラチスコマ27が設けられていることで、塑性ヒンジ部の曲げ変形領域が確保されている。 In the lattice material 26, the bent portion, which is a portion where the straight portions 26A and 26B and the inclined portion 26C intersect, is a plastic hinge portion. This plastic hinge portion corresponds to an energy absorption portion that bends and deforms to absorb vibration energy when an external force such as a seismic force is applied, and is a portion where a plastic hinge is formed by yielding a cross section due to a load. Further, in the lattice material 26, the bending deformation region of the plastic hinge portion is secured by providing the lattice piece 27.

<耐火被覆材>
図1に示す耐火被覆材36は、一例として、ロックウールを含んで構成されている。また、耐火被覆材36は、Z方向から見た場合に、Y方向の屋外側に向けて開口するU字状に配置されている。さらに、耐火被覆材36は、Z方向に沿って、重ならずに接触した状態で複数並べられている。加えて、耐火被覆材36は、外壁パネル16と共に、鉄骨柱22、鉄骨柱24及びラチス材26(補助断熱材34、35及び断熱材28を含む)を囲んでいる。そして、耐火被覆材36の一部は、図示しない溶接ピンを用いて鉄骨柱22及び鉄骨柱24にスタッド溶接により固定されると共に、図示しないビスを用いて外壁パネル16に固定されている。
<Fireproof coating material>
The refractory coating material 36 shown in FIG. 1 is configured to contain rock wool as an example. Further, the fireproof coating material 36 is arranged in a U shape that opens toward the outdoor side in the Y direction when viewed from the Z direction. Further, a plurality of refractory coating materials 36 are arranged in contact with each other along the Z direction without overlapping.

補助断熱材34は、外壁パネル16と鉄骨柱22との間に配置されており、一例として、外壁パネル16、鉄骨柱22、断熱材28及び耐火被覆材36に接触している。これにより、補助断熱材34は、外壁パネル16と鉄骨柱22との間で断熱するようになっている。また、補助断熱材34のX方向の長さL9は、一例として、鉄骨柱22の長さL4よりも長い。補助断熱材34におけるX方向の他方側(断熱材28側とは反対側)の側面34Aは、Z方向から見た場合に、鉄骨柱22の側面22DとY方向にほぼ揃えられている。つまり、補助断熱材34は、Z方向から見た場合に、鉄骨柱22に対して断熱材28側に突出された状態で、断熱材28と接触している。 The auxiliary heat insulating material 34 is arranged between the outer wall panel 16 and the steel frame column 22, and is in contact with the outer wall panel 16, the steel frame column 22, the heat insulating material 28, and the fireproof coating material 36 as an example.

〔作用〕
次に、本実施形態の作用について説明する。
[Action]
Next, the operation of this embodiment will be described.

図5(A)に示すように、ラチス材26により連結された鉄骨柱22及び鉄骨柱24が、Z方向に沿って立設される。また、外壁パネル16が、図示しない外壁フレームに取付けられることで、鉄骨柱22、ラチス材26及び鉄骨柱24に対する屋外側にZ方向に沿って配設される。これにより、鉄骨柱22、ラチス材26及び鉄骨柱24と、外壁パネル16との間に空間部29が形成される。さらに、補助断熱材34及び補助断熱材35が、X方向の外側から外壁パネル16と鉄骨柱22との間、及び外壁パネル16と鉄骨柱24との間に挿入されることで、配置される。 As shown in FIG. 5A, the steel frame columns 22 and the steel frame columns 24 connected by the lattice material 26 are erected along the Z direction. Further, by attaching the outer wall panel 16 to an outer wall frame (not shown), the outer wall panel 16 is arranged along the Z direction on the outdoor side with respect to the steel frame column 22, the lattice material 26, and the steel frame column 24. As a result, the space portion 29 is formed between the steel frame column 22, the lattice material 26 and the steel frame column 24, and the outer wall panel 16. Further, the auxiliary heat insulating material 34 and the auxiliary heat insulating material 35 are arranged by being inserted between the outer wall panel 16 and the steel frame column 22 and between the outer wall panel 16 and the steel frame column 24 from the outside in the X direction. ..

続いて、図5(B)に示すように、断熱材28が、ラチス材26に対する屋内側から貫通部31を通過して、外壁パネル16(図5(A)参照)とラチス材26との間(空間部29)に配置される(第1工程の一例)。 Subsequently, as shown in FIG. 5 (B), the heat insulating material 28 passes through the penetrating portion 31 from the indoor side with respect to the lattice material 26, and the outer wall panel 16 (see FIG. 5 (A)) and the lattice material 26 It is arranged in the space (space 29) (an example of the first step).

続いて、図5(C)に示すように、断熱材28の第1取付部46が、永久磁石32を用いて鉄骨柱22の側面22Cに取付けられ、第2取付部47が、永久磁石32を用いて鉄骨柱24の側面24Dに取付けられる(第2工程の一例)。これらの工程は、複数の断熱材28のそれぞれについて行われる。 Subsequently, as shown in FIG. 5C, the first mounting portion 46 of the heat insulating material 28 is mounted on the side surface 22C of the steel frame column 22 using the permanent magnet 32, and the second mounting portion 47 is the permanent magnet 32. Is attached to the side surface 24D of the steel frame column 24 (an example of the second step). These steps are performed on each of the plurality of insulation materials 28.

続いて、図1に示すように、鉄骨柱22、24、ラチス材26、補助断熱材34、35及び断熱材28が、耐火被覆材36により屋内側から覆われる。耐火被覆材36の一部は、図示しない溶接ピンを用いて鉄骨柱22及び鉄骨柱24にスタッド溶接される。そして、耐火被覆材36のX方向の両端部(第3耐火部36C)が、外壁パネル16の屋内側に図示しないビスにより固定される。このようにして、耐火壁構造20が出来上がる。なお、耐火被覆材36を設けた後で、耐火被覆材36に対する屋内側に石膏ボード38が設けられる。 Subsequently, as shown in FIG. 1, the steel frame columns 22, 24, the lattice material 26, the auxiliary heat insulating materials 34, 35, and the heat insulating material 28 are covered with the fireproof coating material 36 from the indoor side. A part of the refractory coating material 36 is stud welded to the steel column 22 and the steel column 24 using a welding pin (not shown). Then, both ends of the fireproof coating material 36 in the X direction (third fireproof portion 36C) are fixed to the indoor side of the outer wall panel 16 by screws (not shown). In this way, the refractory wall structure 20 is completed. After the fireproof coating material 36 is provided, the gypsum board 38 is provided on the indoor side of the fireproof coating material 36.

以上、説明したように、耐火壁構造20及び耐火壁構造20の施工方法では、外壁パネル16、鉄骨柱22、24及びラチス材26が設けられた後で、ラチス材26に対する屋内側から、ラチス材26と外壁パネル16との間に断熱材28を取付ける作業を行える。このため、外壁パネル16が配置される前に、外壁パネル16の配置を考慮しながら断熱材28の配置を行う必要がなくなる。つまり、断熱材28の配置作業をラチス材26に対する屋内側から簡単に行うことができるので、断熱材28を有する耐火壁構造において、施工性を向上させることができる。 As described above, in the method of constructing the refractory wall structure 20 and the refractory wall structure 20, after the outer wall panel 16, the steel frame columns 22, 24 and the lattice material 26 are provided, the lattice material 26 is viewed from the indoor side. The work of attaching the heat insulating material 28 between the material 26 and the outer wall panel 16 can be performed. Therefore, it is not necessary to arrange the heat insulating material 28 while considering the arrangement of the outer wall panel 16 before the outer wall panel 16 is arranged. That is, since the work of arranging the heat insulating material 28 can be easily performed from the indoor side with respect to the lattice material 26, the workability can be improved in the refractory wall structure having the heat insulating material 28.

また、耐火壁構造20では、外壁パネル16と鉄骨柱22、24との間に補助断熱材34、35が配置される。さらに、補助断熱材34、35は、外壁パネル16とラチス材26との間に配置された断熱材28と接触する。これにより、外壁パネル16と鉄骨柱22、24との間の空間に、断熱材28及び補助断熱材34、35が、X方向に沿って連続して配置されることになるので、補助断熱材34、35を配置しない構成に比べて、耐火壁構造20の断熱性能を高めることができる。 Further, in the refractory wall structure 20, auxiliary heat insulating materials 34 and 35 are arranged between the outer wall panel 16 and the steel frame columns 22 and 24. Further, the auxiliary heat insulating materials 34 and 35 come into contact with the heat insulating material 28 arranged between the outer wall panel 16 and the lattice material 26. As a result, the heat insulating material 28 and the auxiliary heat insulating materials 34 and 35 are continuously arranged along the X direction in the space between the outer wall panel 16 and the steel frame columns 22 and 24. The heat insulating performance of the fireproof wall structure 20 can be improved as compared with the configuration in which 34 and 35 are not arranged.

さらに、耐火壁構造20では、取付部44が、永久磁石32と、鉄骨柱22、24とで挟まれることで、永久磁石32と鉄骨柱22、24との引合う力(磁力)によって、鉄骨柱22、24に取付けられる。言い換えると、鉄骨柱22、24に取付部44を接触させた状態で、永久磁石32を取付部44に近づけるだけで、永久磁石32と鉄骨柱22、24とが引合って、取付部44が取付けられる。これにより、鉄骨柱22、24に断熱材28を取付ける作業を簡単に行うことができる。 Further, in the fireproof wall structure 20, the mounting portion 44 is sandwiched between the permanent magnet 32 and the steel frame columns 22 and 24, and the steel frame is generated by the attractive force (magnetic force) between the permanent magnet 32 and the steel frame columns 22 and 24. It is attached to columns 22 and 24. In other words, when the permanent magnet 32 is brought close to the mounting portion 44 with the mounting portion 44 in contact with the steel frame columns 22 and 24, the permanent magnet 32 and the steel frame columns 22 and 24 are attracted to each other, and the mounting portion 44 is moved. Can be installed. As a result, the work of attaching the heat insulating material 28 to the steel frame columns 22 and 24 can be easily performed.

なお、本発明は上記の実施形態に限定されない。 The present invention is not limited to the above embodiment.

耐火壁構造20において、補助断熱材34、35を設けずに、断熱材28の一部を外壁パネル16と鉄骨柱22、24との間に押込むように構成してもよい。また、鉄骨柱22、ラチス材26及び鉄骨柱24を単位ユニットとして、この単位ユニットをX方向に2つ以上設けて、それぞれの単位ユニット毎に断熱材28を配置してもよい。さらに、耐火壁構造20において、外壁パネル16、鉄骨柱22、ラチス材26及び鉄骨柱24が並ぶ方向は、X方向に限らず、Y方向であってもよい。 In the refractory wall structure 20, a part of the heat insulating material 28 may be pushed between the outer wall panel 16 and the steel frame columns 22 and 24 without providing the auxiliary heat insulating materials 34 and 35. Further, the steel frame column 22, the lattice material 26, and the steel frame column 24 may be used as unit units, and two or more of these unit units may be provided in the X direction, and the heat insulating material 28 may be arranged for each unit unit. Further, in the refractory wall structure 20, the direction in which the outer wall panel 16, the steel frame column 22, the lattice material 26, and the steel frame column 24 are arranged is not limited to the X direction, but may be the Y direction.
